Not bad, all things considered. Beautiful wife, two amazing kids, home in a town I love, a fecund backyard garden.<br />
<div>
<br /></div>
<div>
As I roll over another zero into the units digit of the odometer of life, something interesting happened that has caused me to reconnect with - and think about - a lot of the people I went to high school with.</div>
<div>
<br /></div>
<div>
That something interesting is <a href="http://www.facebook.com/nick.noodlebook">Facebook</a>. Over the the span of two years, my entire graduating class from Davis Senior High School seemed to suddenly show up and start friending each other. I kept in touch with very few people from home and so I've been reconnecting, after twenty years, with the people I grew up with. I've learned about their lives and seen photos of their kids and read about their travels.</div>
<div>
<br /></div>
<div>
And I mean <i>your</i> lives and <i>your</i> kids and <i>your</i> travels: because I'm talking to you, graduating class of 1989. And, to be fair, a few of you who graduated a year or two earlier or later who I was close enough with that I think of you as part of my class.</div>
<div>
<br /></div>
<div>
Back then we were, with apologies to <a href="http://www.imdb.com/title/tt0088847/">John Hughes</a>, brains, musicians, jocks, partiers, and goths. We hung out in our cliques and did our different activities. We crossed social boundaries sometimes, uneasily and tentatively. But it was high school and we all had our domains and our coteries. But we were also all a bunch of kids growing up in a reasonably affluent university town on the edge of some very good farmland.</div>
<div>
<br /></div>
<div>
We didn't know it then, but we were all so damn alike that the only thing we could focus on was our differences.</div>
<div>
<br /></div>
<div>
Fast forward twenty years or more.</div>
<div>
<br /></div>
<div>
What are we now? Who are we now?</div>
<div>
<br /></div>
<div>
We are fathers, we are mothers, we are married, we are single, we are divorced.</div>
<div>
<br /></div>
<div>
We are gay, we are straight, we are flexible.</div>
<div>
<br /></div>
<div>
We are conservative, we are liberal, we are undecided.</div>
<div>
<br /></div>
<div>
We are project managers, we are musicians, we are farmers, we are entrepreneurs, we are artists, we are lawyers, we are restauranteurs, we are law enforcement officers, we are opera singers, we are bartenders, we are writers, we are programmers, we are veterinary pathologists.</div>
<div>
<br /></div>
<div>
A staggering number of us are teachers.</div>
<div>
<br /></div>
<div>
Some of us are expatriates, some of us never left town, some of us have come back home.</div>
<div>
<br /></div>
<div>
At least one of us has been to war.</div>
<div>
<br /></div>
<div>
A very few of us have died.</div>
<div>
<br /></div>
<div>
So much diversity, so much variety of experience and outcome. And yet today I feel closer to a broader range of the people that made up my graduating class than I ever have.</div>
<div>
<br /></div>
<div>
What happened?<br />
<br />
We all went on that strange, crooked pathway called life. No one took a path that quite matched what they expected or what anyone else expected for them. Some paths were radically surprising, some merely crooked. Some triumphant, some quotidian.</div>
<div>
<br /></div>
<div>
If there had been a yearbook category "Most likely to play in a major symphony orchestra," I think the predictions might have been pretty good. But I doubt that the eventual winners of "Most likely to raise backyard chickens" or "Most likely to post photomicrographs to Facebook" or "Most likely to become the leading academic authority on American Idol" would have been so obvious back in 1989.</div>
<div>
<br /></div>
<div>
In 2011, we all sit down at the end of the day and try to unwind from the stresses of an adult life, whatever form that life might take. We might worry about the economy or climate change or health care or school selection or taxes or bills or the future. We might have a glass of beer or wine or bourbon or tea or coffee to help us relax. We might unwind playing a LARP or watching a show or hitting a round of golf or going for a run or pushing through a Crossfit WOD.</div>
<div>
<br /></div>
<div>
But it is the journey, from a small town on the outskirts of Sacramento to here, wherever here is and whatever waypoints passed on the way, that has brought us closer. We've learned about ourselves and about each other, about what it means to be a man or a woman in the world.</div>
<div>
<br /></div>
<div>
Twenty years on, we are all now so different that all we can do is focus on our similarities.</div>
<div>
<br /></div>
<div>
Hello again, graduating class of 1989, it is a real pleasure to get to know you.</div>
<div>

Fields of them ringed the town. Cropdusters buzzed low keeping them pest and disease free. Trucks of them drove in to town, to the local cannery and processing factory.</div><div><br /></div><div>Every summer, tomatoes, spilled off the top of overloaded trucks, lay rotting in the gutters all through the July and August heat.</div><div><br /></div><div>When someone says "the smell of boiling tomatoes" to you, it may conjure up the image of a nice tomato sauce or soup, simmering away on the stove. To me it conjures up months of steamy emissions from the plant, drifting in to town, an indecisive miasma, unsure if it was sweet or savory.</div><div><br /></div><div>Sometimes, when money for our family was tight, my mom would take seasonal work at the factory, working on the line and later at their paste processing facility. She came home redolent of tomatoes, the smell impregnated into her clothing.</div><div><br /></div><div>So perhaps I have a love/hate relationship with the tomato. It, after all, brought in a non-trivial part of my family's income through some tough years. My grandmother was a bookkeeper at the plant, and my grandfather flew some of those cropdusters for many years until he wrecked and was relegated to golfing and reading about the Civil War.</div><div><br /></div><div>Out in my own garden, while <a href="http://nwedibles.blogspot.com/2011/02/heat-lovers-in-cool-clime-tomato-dreams.html">we try our best to raise a decent crop</a>, I'll rail against their overly-hybridized fussiness. I'll complain about their sprawling untidiness. I'll jump on any excuse to get these unnatural things, never meant for the maritime northwest, out of the garden.</div><div><br /></div><div>But I must be honest with myself and acknowledge a couple of things about the tomato. First off, it is all those things - hybridized to the point of absurdity and totally ill suited for where we grow it. But these very characteristics are the source of the challenge, a sort of backyard agronomic "because it is there" factor, that forces all of us gardeners west of the Rain Shadow to test their mettle against this thing.</div><div><br /></div><div>Because <i>if</i> you can grow it, get your crops to ripen up into something more than pickled, fried, or salsafied green tomatoes, then you have truly shown what you are worth.</div><div><br /></div><div>You are a <i>gardener</i>, you have not shirked from the greatest of challenges but embraced them. And you have come away the champion.</div><div><br /></div><div>And after a few years of perseverance (or of head-into-wall-beating, if you prefer) a good crop <i>will</i> come up. Tomatoes are a heartbreak crop, in the words of my brother in law - they reward you just on the edge of abandonment, dole out a good harvest to keep you going. Those good crops, when they happen, are<i> </i>so good and so worth it. Romas, big slicers, cherries and grapes, crazy heirlooms in all variety of colors from tacky lipstick pink to the deepest of purples. The thousand and one flavors, not the giant soggy slicers of supermarket burger filling fame.</div><div><br /></div><div>So remind me of this, next time I'm standing ankle deep in rotting tomato flesh, pulling fungus dappled vines out of the ground, raising my fist at the sky and reliving every tomato-stinking summer of my youth. Remind me that sometimes they <i>do</i> work out and when it happens, the rewards are rich!</div><div><br /></div><div>Footnote: while researching this post and looking for photos, I found out that the <a href="http://daviswiki.org/Hunt_Wesson_Plant">factory in question was demolished</a>. I knew <a href="http://articles.latimes.com/1999/oct/14/business/fi-22065">it had closed</a>, and good riddance at this point, but as much as my memories of it are of bad smells, night-shift-working-mom, and traffic snarling trucks, a part of my youth is now gone.</div>Just Nickhttp://www.blogger.com/profile/01845987547854457407noreply@blogger.com0tag:blogger.com,1999:blog-5333608194352082143.post-4299259324544146722011-02-20T18:36:00.000-08:002011-02-21T07:52:30.431-08:00My Urban Homesteads<div>I live in at least two different Urban Homesteads.<div><br /></div><div>One of them is the one that I return to, every night, at the end of a dead end street in a small town just north of Seattle. It is the homestead that grows most of our vegetables, that does not yet have chickens, that often smells of slowly simmering stews or reducing sauces. <a href="http://nwedibles.blogspot.com/">Erica writes about it</a>, I brew beer in it, we raise our family in it.</div><div><br /></div><div>It is home.</div><div><br /></div><div>But I have another urban homestead. It is somewhere on the banks of a fast moving river, a couple of acres of fields growing organic garlic to sell on the farmer's market circuit, some raised beds for our own veggies, a stand of hop vines trellising a dozen or so feet into the air, chickens running underfoot, a detached garage for the tractor.</div><div><br /></div><div>At this second homestead, nothing ever breaks or needs maintenance, not even the John Deere. The weather is always just challenging enough to test our agricultural mettle but never so threatening as to actually spoil a crop. At this homestead, I've traded my high rise job for something virtual - perhaps I've finally sold a novel or parleyed my occasional speaking gigs to some sort of guru position in the business intelligence world and now sell online consulting time and the occasionally well compensated keynote.</div><div><br /></div><div>By now you may realize that this second urban homestead doesn't really exist - not anywhere you can find, at least. And isn't all that urban, come to think of it. It is the homestead of my dreams, my escape and my folly, a happy place that sustains me when the here and the now bring their dull, unrewarding, tedious best to bear.</div><div><br /></div><div>That first homstead, the one with an address, the one you can spot on Google Earth, is a great place and every night it welcomes me home.</div><div><br /></div><div>But when I can't be there, the other homestead that helps me through, the fantasy homestead. So when the conference calls are particularly boring, the traffic across the bridge particularly tedious, or the speaker meandering on far too long, there is always something to do:</div><div><br /></div><div><a href="http://www.deere.com/en_US/ProductCatalog/FR/category/FR_TRACTORS.html">Shopping for tractors</a> on the John Deere website.</div><div><br /></div><div>Reviewing <a href="http://attra.ncat.org/attra-pub/garlic.html">organic garlic production techniques</a> put out by the NSAIS.</div><div><br /></div><div>Choosing favorite breeds from <a href="http://www.ithaca.edu/staff/jhenderson/chooks/chooks.html">Hnderson's Chicken Breed Chart</a>.</div><div><br /></div><div>Planning <a href="http://www.bergey.com/pages/excel_info">alternative energy systems</a>.</div><div><br /></div><div>Catching up on reading from the <a href="http://extension.wsu.edu/agriculture/Pages/default.aspx">local agriculture extension program</a>.</div><div><br /></div><div>Yes, I'm a dreamer. But anyone chasing the urban homestead dream is almost by definition a dreamer. Even my real urban homestead has a place for dreams - chickens, more cheese making, more trees, the next batch of beer I'm brewing, tree selection for the expanded orchard, a rainwater recycling system. So dream on, urban homesteaders. Dreams go with the territory.</div></div>Just Nickhttp://www.blogger.com/profile/01845987547854457407noreply@blogger.com2tag:blogger.com,1999:blog-5333608194352082143.post-11119127135571969592011-02-17T15:10:00.000-08:002011-02-19T10:08:16.587-08:00An Open Letter to the Dervaes'<p class="MsoNormal"><span class="Apple-style-span" style="font-size: medium; ">Well it is a mighty fine <a href="http://nwedibles.blogspot.com/2011/02/i-am-urban-homesteader-nyah-nyah.html">mess you have created</a>. Yes, Dervaes family, urbanhomestead.org, you have really managed to do something profound to the community you helped create.</span></p><p class="MsoNormal"><span class="Apple-style-span">You have chosen to <a href="http://www.thecrunchychicken.com/2011/02/urban-homesteaders-cease-and-desist.html">trademark a whole host of terms</a>, ostensibly seeking to protect them from those who would misuse and abuse them for their own profit. I’ve got some respect for this – after all, it is easy enough to imagine the Monsanto Urban Homesteader collection of seeds or the Lowe’s Urban Homesteader Twice-A-Year Sale.</span></p><p class="MsoNormal"><span class="Apple-style-span">Unfortunately, there are a couple of problems with this.</span></p><p class="MsoNormal"><span class="Apple-style-span">First off, you weren’t there first. A quick bit of online research finds the phrase “urban homestead” in some variation or the other dating back to the 1970s or before. But the legitimacy of your claim isn't the greatest issue here.</span></p><p class="MsoNormal"><span class="Apple-style-span">The urban homesteading movement (by whatever name you wish it to go by) is a tenuous thing. We are decentralized. We come from a range of social, political, and moral backgrounds. We’ve come to this for a variety of reasons: health, environment, economics, survival, enjoyment. We practice in varied ways as suit our varied natures and regions: poultry, fruit, vegetables, livestock, dairy.</span></p><p class="MsoNormal"><span class="Apple-style-span">We run the risk of appearing as freaks and finding ourselves further marginalized just as we are gaining traction and awareness.</span></p><p class="MsoNormal"><span class="Apple-style-span">So here we stand, not on the cusp of victory by any means, but on the cusp of moving to a greater playing field. The values we espouse are being picked up by authors, chefs, and social commentators and spreading to an ever broader audience. The tools and supplies we need are available more easily as more and more people show an interest in a backyard orchard or some raised beds or a chicken coop. Laws are making it easier for us to practice what we believe in (I’m talking about how my town repealed a ban on backyard poultry last year…but I’m sure there are others).</span></p><p class="MsoNormal"><span class="Apple-style-span">Just as things start to take off, do we really want to risk going from respect to mockery? Think of it this way: which headline would you rather see CNN or The New York Times run next week?<br /><o:p></o:p></span></p><p class="MsoNormal"><span class="Apple-style-span" style="font-size: medium; "></span></p><blockquote><span class="Apple-style-span">In yards around the nation, Urban Homesteading taking off!</span></blockquote><p></p><p class="MsoNormal"><span class="Apple-style-span">Or</span></p><p class="MsoNormal"><span class="Apple-style-span" style="font-size: medium; "></span></p><blockquote><span class="Apple-style-span">Urban gardens taking off, but don’t call them homesteads!</span></blockquote><p></p><p class="MsoNormal"><span class="Apple-style-span">Do we want to risk drifting into that part of the news day usually called “the lighter side” where mainstream America pokes fun (often deservedly) at people who lie just a little too far outside the bell curve or normality?</span></p><p class="MsoNormal"><span class="Apple-style-span">Perhaps even more critically, do we want to see the common idea that binds us together torn asunder because of the lack of a word, an all important linguistic thread that weaves between all of our diverse backgrounds, motivations, and interests? For words have meaning and power well beyond their superficial sounds and definitions. They provide identity, meaning, and community. They define and establish boundaries of inclusion and exclusion. Their proper use is a Shibboleth demarking true believers from tourists and pretenders.</span></p><p class="MsoNormal"><span class="Apple-style-span">Do we want to risk Balkanizing ourselves into urban homesteaders, city farmers, metropolitan agronomists, backyard growers, and the hundreds of other permutations I could devise, each one separated by a shade of meaning, a subtlety of belief or background or motivation? “Oh no, I’m not a city farmer, those are people with apartments. I’m a metropolitan agronomist because I practice square-foot techniques outside of the city core.”</span></p><p class="MsoNormal"><span class="Apple-style-span">Hyperbole on my part? Yes, but exaggeration and humor to make a point.</span></p><p class="MsoNormal"><span class="Apple-style-span">So perhaps, Derveases, we misunderstood you and your intentions were pure if ill communicated. Personally, I don’t think you were trying to shut down the use of the words Urban and Homesteading. I think you were trying to drive site (and store) traffic by intimidating bloggers, libraries, and authors into offering you a credit and a link. But my suspicious are beside the point.</span></p><p class="MsoNormal"><span class="Apple-style-span">Your blog posts and tweets profess surprise at the community’s reaction and accuse those of us with some spleen to vent of misunderstanding your intentions. They read accusingly, saying that this misunderstanding is our fault. They make us feel bad for the hurt they have caused your family, the tears brought on by our impassioned words.</span></p><p class="MsoNormal"><span class="Apple-style-span" style="font-size: medium; ">Then why, I ask, were your first attempts to control the use of these terms targeted at a library and a blogger? Why do you respond with a series of defensive tweets and a blog update that cries out how hard this has been on you?</span></p><p class="MsoNormal"><span class="Apple-style-span">Welcome to the big time, Urban Homestead. Success is a bitch, that high profile you’ve worked to build up means there are a lot of people watching you – but that’s what you wanted, right? You came across as the big bad, swinging a legal claim, no matter how indefensible it may be, to get your way and get your due credit. People reacted in a way you didn't expect (really?), in a way that hurt you.</span></p><p class="MsoNormal"><span class="Apple-style-span">And the result has been bad, very bad. Whether you intended to deny use of these terms to the community at large or not, that is how we have understood your actions. And that is what is driving our reaction.</span></p><p class="MsoNormal"><span class="Apple-style-span">The point is that your actions, however they were intended, have jeopardized the movement you helped spawn. Your intentions are irrelevant. The results of your implementation and the broader community’s perception of that implementation are what matter – and the perception of that perception, but I risk losing my way. You have children and so know that intentions count for only so much. Results, whether those intended or expected or not, are what matter. And so you must choose your future actions based not around your professed or actual intent but around the reality in which you find yourself – an unpleasant reality with no easy choices.</span></p><p class="MsoNormal"><span class="Apple-style-span">And it is by those actions that the rest of us urban homesteaders, who owe you so much, will judge you and assess your intentions.</span></p><p class="MsoNormal"><span class="Apple-style-span">How should you react now that you’ve enraged a good portion of the community? Your blog and tweets profess surprise at this reaction, accuse us of misunderstanding your intentions.</span></p><p class="MsoNormal"><span class="Apple-style-span">I’m going to assume that you genuinely believe in the movement of which you have been such a part and that you have the best interest of that movement at heart – and you should, for to try to put your own business success ahead of that of the movement at large is to jeopardize not only your relationship with the movement but the very success of the movement itself. And I hope that you recognize this relationship and do what is best not for your own short-sighted gain but rather for the continued growth of this community and your relationship with it.</span></p><p class="MsoNormal"><span class="Apple-style-span">What you need to do is take charge of this situation. Yes, I said take charge. After accusing you of heavy handedness (intentional or not) why do I say you should take charge?</span></p><p class="MsoNormal"><span class="Apple-style-span">Because you have a window of opportunity to try and save some face. You will never regain the full respect you had in the community, but that’s done. Time for damage control, time for clear words and clear actions. Time to do things that will not be misunderstood (again).</span></p><p class="MsoNormal"><span class="Apple-style-span">Cede the word to the community.</span></p><p class="MsoNormal"><span class="Apple-style-span">Stand up and in clear simple words admit that you erred:</span></p><p class="MsoNormal"><span class="Apple-style-span">Say “we never intended to deny the broader use of these words.”</span></p><p class="MsoNormal"><span class="Apple-style-span">Say “but unfortunately our actions were misunderstood.”</span></p><p class="MsoNormal"><span class="Apple-style-span">Say “we never anticipated the depth of feeling our actions would arouse.”</span></p><p class="MsoNormal"><span class="Apple-style-span">Say “but observing the passion of the community we helped foster is as gratifying as it has been troubling.”</span></p><p class="MsoNormal"><span class="Apple-style-span">Say “and so we waive our claim to these trademarks.”</span></p><p class="MsoNormal"><span class="Apple-style-span">Say “we recognize that these phrases are something larger than our family and our farm.”</span></p><p class="MsoNormal"><span class="Apple-style-span">Say “these words are our movement and they are your movement.”</span></p><p class="MsoNormal"><span class="Apple-style-span">And then shut the hell up.</span></p><p class="MsoNormal"><span class="Apple-style-span">We will have our community. There is the risk that these words will get misused, co-opted. But we do not need your protection and we know what an urban homestead really is without your oversight and editing.</span></p><p class="MsoNormal"><span class="Apple-style-span">As it stands right now, <a href="http://urbanhomestead.org/journal/2011/02/17/we-are-urban-homesteaders/">your website</a> leaves you an opening. Make that promised press release a thing of nobility, of admission, and of generosity. Play it right and you might even come out looking pretty good.</span></p><p class="MsoNormal"><span class="Apple-style-span"><span>I fear that you will take one of the easier paths. Perhaps you will take the easiest, that of stepping away from the issue, never following up on your letters, of hoping that things die down. And they might. Your reputation will never rebuild, not with those of us who live at the core of this movement. We’ll make jokes. We’ll refer to someone as “pulling a </span><span class="apple-style-span"><span>Dervaes” when they try a petty trade marking or some cheesy legal intimidation.</span></span></span></p><p class="MsoNormal"><span class="Apple-style-span">There is another path I fear, one that is harder for you and worse for the community. It is the path of pride, of stonewalling and digging in. Of perceiving the community’s response as some sort of a threat to some position of hierarchy that you believe you deserve. This is the path that leads to mockery of our movement, of factionalized collapse into urban homesteaders vs. metropolitan farmers vs. city gardeners. This is the path that leads to a legal fight you will not win, that will only drain your finances and threaten your very livelihood.</span></p><p class="MsoNormal"><span class="Apple-style-span">So I ask you, think it through. Make a decision, a tough decision. Retake what you can of the leadership you had in this community. Give us that community, without a fight, without shame, and without guilt.<o:p></o:p></span></p><p class="MsoNormal"><span class="Apple-style-span">As I write this, your latest blog entry is "<a href="http://urbanhomestead.org/journal/2011/02/17/we-are-urban-homesteaders/">we are urban homesteaders</a>." I do not deny that. But so are we.</span></p><p class="MsoNormal"><b>UPDATED 2/18/2011</b></p><p class="MsoNormal">For starters I want to thank everyone for their kind comments. I'm glad I could help lend some voice to everyone's emotions.</p><p class="MsoNormal">I deliberately tried to keep the issue of the legitimacy of the Dervaes' claims - whether legal or moral - out of this. For starters the two are quite different - they might <i>legally</i> be able to maintain control over a trademark that we do not feel they <i>morally</i> should be able to. But more than that, I'm no lawyer and while my experience around issues like this gives me some opinions and expectations, I don't want to put my foot in it by delving into idle speculations.</p><p class="MsoNormal">In the meantime, as well, the <a href="http://news.yahoo.com/s/usnw/20110218/pl_usnw/DC50891">promised press release is out</a>. It offers (a little) more information about their intentions, but generally continues the theme of "we didn't do what you are saying we did" that permeated the output from urbanhomestead.org on 2/17. Granted, it is in nicer language and they fixed some of the grammar problems (yes, I get irritated at tweets with grammar or vocabulary mistakes, that's one of the side effects of having a BA in English).</p><p class="MsoNormal">It still, however, misses a crucial point: what do you INTEND to do. They deny filing legal actions, however "informational letters" are typically a prelude to some other sort of action. They do not mention the DMCA requests to Google. It continues a disingenuous attempt to portray them as victims of a disproportionate response to innocent actions. It will do little, if anything, to quell the communities reaction.</p><p class="MsoNormal">What is made clearer is that the Dervaes family views the growing popularity of this movement as a threat to their perceived position of leadership. Too soon, guys, too soon. Yes, the time will come for squabbling and internecine fighting, but that time is not now. We are still in the "a rising tide lifts all boats" stage where supporting the greater cause will build the market. This attempt to gain control<i> </i>may help build <i>market share</i> but controlling a larger portion of a smaller or more slowly growing market is not advantageous in an absolute sense.</p><p class="MsoNormal"><a href="http://en.wikipedia.org/wiki/Pyrrhic_victory">Pyhrric victory</a>, anyone? A scorched earth retreat across the burning fields of urban homesteads is not the way to maintain position.</p><p class="MsoNormal">Right now we are still growing, still need to build community and identity. I work in an industry that is at market saturation and so we see <a href="http://www.eweek.com/c/a/Mobile-and-Wireless/Nokias-Apple-Lawsuit-Deepens-A-LongRunning-Conflict-606927/">crazy legal actions</a> all the time, companies claiming too have invented whole ideas. Why? Because everyone already wants a cell phone. Every one knows what they are. Everyone wants one. So the bickering begins. </p><p class="MsoNormal">But imagine if, in the 1970's Bell Labs had trademarked the phrase "Cell Phone" and variants and then, in the 1980's when the devices started to become popular, chosen to protect that trademark. Things might have turned out differently if we had lacked a common phrase to describe that thing that we hold up to our ear to talk on when we aren't at home. Granted, there are dozens of synonyms (including bizarre new ones like "converged device"...I mean...really?) but the term "cell phone" got us started.</p><p class="MsoNormal">On Facebook, I've contrasted the Dervaes' attempted actions with <a href="http://en.wikipedia.org/wiki/Charlie_Papazian">Charlie Papazian</a>, one of the founders of the American homebrewing movement.

Papazian is revered as a guru, a founder, an inspiration. I actually don't particularly care for his writing (a little too 1970's "relax and have a homebrew for me...I like a little more microbiology in my beer books) but if I ran into him at a convention (and if I could get through the rings of people looking for his autograph, opinion, photo op, etc.) I'd shake his hand and know I'd touched someone without whom my hobby may not exist.</p><p class="MsoNormal">Yet he, despite having at least as much right to claim ownership of homebrewing as the Dervaes' do of urban homesteading, never made any move to protect that claim. Perhaps it was that 1970's "relax and have a homebrew" attitude. Instead he threw his weight into growing the movement as a whole, founding organizations, writing books, promoting the entire idea. And now, like I said, guru status and a million books out there.</p><p class="MsoNormal">Compare and contrast. And remember, a rising tide lifts all boats. Take care of those around you and they will take care of you.</p><p class="MsoNormal">You, Dervaes' are in the unenviable position of needing to react to a situation that is now well and truly out of your control.

I blame streaming network television, of course, and the Biggest Looser marathon I indulged in while stuck home sick.<br /><br />But seriously, every twelve minutes I was inundated with an advertisement proclaiming a new beer offering the refreshing taste of wheat with the drinkability of Bud Light.<br /><br />Ok, I have some idea of what the refreshing taste of wheat is. Wheat in beer, of course, because last time I sat down with a mug full of freshly husked wheat and tried to drink it I severly lacerated my moutn. Well not really. But you get the idea.<br /><br />In a true beer (a statement that seems to imply that Bud Light Golden Wheat is not a true beer), wheat adds a slightly sweet graniness. I always find that beers with a high wheat content posess a slightly astringent quality, similar to the dryness of a very highly fermented beer. I don't know what causes this sensation, but it seems to naturally balance the malty sweetness that comes from the wheat malt itself.<br /><br />Anyway, I don't as a rule go for beers with a very high wheat content, but have really enjoyed working with it as a component to add a little "something special" to everything from IPA's to light ales.<br /><br />But I digress.<br /><br />This was about bashing Budweiser.<br /><br /></div><div>And this idea of "drinkability." What is "drinkable?" Are they saying that their beer can be consumed in liquid form, in exactly the whay that a cup full of ground wheat cannot? Perhaps that it is relatively thin, low in viscosity, and therefore can be consumed more readily than, say, molasses.<br /><br />But I don't think so. I think that what they are saying is this:<br /><br /></div><div>"Don't worry, you won't be asked to take a risk when you consume this beer!"<br /><br />Yes, "drinkability" is essentially a statement of conformity to the general flavor profile of what we hombrewer's like to call ALL's -- American Light Lagers.<br /><br /></div><div>"Don't worry, you won't be challenged to try something unfamiliar and don't need to risk not liking it."<br /><br />Trying new things always carries a risk. Because, after all, if we spend the energy (time, money, emotional cost) to do something out of the ordinary (say trying a new beer or throwing ourselves out of an airplane with only a rolled up piece of nylon stuffed into a backpack to slow us down), we are investing in that experience. In general, people tend to prefer favorable experiences. It takes a fairly dedicated person to have an unplesant experience and then want to go back for more.<br /><br />Take, for example, the movie Avatar. I didn't like it. After seeing it, while I was glad that I'd done so (and therefore gotten to partake in the whole <i>big deal</i>). But I did look back on that evening and think that perhaps something better might, ultimately, have been a better way to go. On the way home, my wife and I ended up stopping at a Red Robin and consuming a large amount of spicy chicken wings just so we'd be able to point to <i>something</i> enjoyable about the evening.<br /><br />So perhaps the same thing could apply to beer. "Hey," says Joe Sixpack, "I've heard of these new craft brews. I should try one." So Joe goes out and buys a sixer of something tasty. Who knows what...let's assume he isn't really into the subtle (or not so subtle) differences between a Maibock and an IIPA. Perhaps he ends up with a few bottles of Old Rasputin or Dogfish 120 or perhaps with something as prosaic as a Mirror Pond. Let us suppose that Joe dislikes this beer. I wouldn't be surprised if this were to happen -- no disrespect to Joe -- because the entire drinking experience would be wildly different from what he'd expect. Hell, a bottle of Dogfish 120 has been known to send experienced beer aficionados to therapy for weeks. Even if he chose something less extreme it would probably not be a light, thirst quenching, (dare I say) "drinkable" beer. Probably something meant to be consumed more slowly, to be savored.</div><br /><div> </div>And so our Joe Six Pack, for his daring and courage, would be rewarded with five bottles of something he can't stand sitting there in his fridge. He'd tuck back into the turtle shell of macro-brews and never go outside again.<div> </div><div><br /></div><div>Until along comes Golden Wheat and loudly says "yes, you can deviate from the dull tired routine of your life and yet take no risk at all that you'll be surprised by change." Yes, Golden Wheat promises change without change.</div><div><br /></div><div>And that's what this whole blog, that started off talking about beer and detoured through James Cameron's latest overblown film, is about. It is about fear of change. It is about a cowardly refusal to try new experiences (or to stick with them long enough to see if they work out). In a saturated market (let us assume that the macro-brew market is saturated), the only way to gain customer share is to promise that nothing is going to change. And as in macro-brews, so also in so many other areas.</div><div><br /></div><div>And that is sad.</div>Just Nickhttp://www.blogger.com/profile/01845987547854457407noreply@blogger.com1tag:blogger.com,1999:blog-5333608194352082143.post-31869927008907603992009-07-17T11:26:00.000-07:002009-07-17T11:36:29.183-07:0040 years ago...So as we sit in the midst of the 40th anniversary of the Apollo 11 flight (I prefer to think of the anniversary, like the mission itself, as a multi-day event, not just this single moment of “The Eagle has landed”), CNN ran the following article:<br /><br /><a href="http://www.cnn.com/2009/TECH/space/07/17/moon.landing.hoax/index.html">http://www.cnn.com/2009/TECH/space/07/17/moon.landing.hoax/index.html</a><br /><br />And incidentally, as I write this, this article has been moved to the prime spot on cnn.com. Read into that exactly what you want to.<br /><br />The article is a relatively good review of the moon-landing-hoax phenomena. Best of all, it includes a link to the YouTube video of Buzz Aldrin punching a leading conspiracy pusher. You’ve got to love a 72 year old guy who can still lay on one some crank’s chin. Glorious moment.<br /><br />Anyway, what I find kind of depressing about this whole phenomena isn’t the fact that this amazing piece of history (by the way, I DO believe that we landed on the moon) is being attacked. Fine, go ahead, people, and believe your conspiracies. I can go on at great length about why I think people love conspiracies and so on, and will always recommend Foucault’s Pendulum as a good work about the appeal of such ideas (though the book is kind of a typical Umberto Eco slog at times).<br /><br />What gets me, about the moon landing conspiracies in particular, is that they so dramatically discount our (humanity’s) ability to do something extraordinary. They are, in other words, profoundly depressing to me.<br /><br />Most conspiracies, I find, seek to explain titanic events that were actually the result of small actions (e.g. a series of individually minor intelligence failures prevents detection of the attack on Pearl Harbor) as the product of grand and titanic forces (F.D.R. allowed/encouraged the attacks because he needed a way to motivate the American populace). I can get this – we all like someone/thing we can blame. And hanging thousands of lives on a series of minor events just doesn’t have the impact of One Dude Who Did It.<br /><br />Similar theories about regarding the 9/11 attacks. All of them seem predicated on the idea that No One Could Screw Up That Bad. And they replace the series of minor errors with a Grand Conspiracy.<br /><br />There is a theme here – an ugly, mundane, chaotic reality is replaced with something dramatic and populated by super-capable heroes or villains.<br /><br />The moon landing theorists go the other way – and this is what I find so depressing. Instead of a massive, concentrated effort by thousands, pushing technical and human limits, the conspiracy theorists would drag that success down to the level of some 2nd rate work on a sound stage.<br /><br />It is a sad rejection of the capabilities of humanity to take such an achievement and, in the face of all evidence, reject it.<br /><br />It is a sad, mediocre mind that can only find a sense of worth by bring others down to their level.<br /><br />It is a sad commentary that (some) people find it easier to subscribe to a "vision" of mediocrity than to a reality of audacious achievement. Is that number increasing (as the article claims it is) because time is passing and a younger generation (understandably) finds it hard to imagine a world, 40 years gone, where humans could walk on the moon? Or is it increasing out of a gradual settling of goals and visions, a drooping of expectations and efforts from struggling for grand, shared visions to a selfish assumption of ease and entitlement?<br /><br />Yours, in hope of audacity, that we may remember and recognize what we all (and all of us) are capable of.<br /><br /> --NickJust Nickhttp://www.blogger.com/profile/01845987547854457407noreply@blogger.com0tag:blogger.com,1999:blog-5333608194352082143.post-52791710682869799952009-05-17T10:40:00.001-07:002009-05-17T10:40:56.510-07:00Boldly going...or is it going boldly?<strong>Top fifteen things I like about the new Star Trek </strong>(and please note that the following list <em>may</em> contain spoilers but will do so somewhat incidentally and is not a plot summary):<br /><br />15) Has the courage to <a href="http://en.wikipedia.org/wiki/Split_infinitive">split the infinitive</a> and go with the original "to boldly go" construction. FYI, I am with that faction of writers and grammarians (probably because I am more writer than grammarian) that accepts that in certain situations a spit infinitive is an entirely acceptable thing to do and may, in fact, have dramatic, narrative, or stylistic advantages (such as here, where "boldly" gets more emphasis by virtue of its placement).<br /><br />14) <a href="http://en.wikipedia.org/wiki/Christopher_Pike_(Star_Trek)">Captain Pike</a> shows Kirk up as a girly man. More seriously, I liked the contrast between the old (but somewhat free thinking) commander and the young (and entirely free thinking) commander. Pike is what Kirk will become after he cooks for a few years...and Pike I suspect sees Kirk as what he was like before he'd had a chance to cook himself.<br /><br />13) No Borg. I was afraid that they'd try to have some Borg backstory going on -- they are a fantastic enemy but are very much a product of the latter instances of the show. And besides, <em>First Contact</em> already did a pretty strong time-travel-Borg themed story (and did it very well).<br /><br />12) The alternate-history reboot meant that I actually thought some of the principle characters might die. Gone was the easy ability to predict which characters would live and which would die.<br /><br />11) Speaking of alternate histories, they avoided the "and the boy woke up" conceit and decided to stick with the new history that they created, rather than having some dramatic event result in a bright flash of light and a cut to some scene that made it clear that we were <em>back</em> in the traditional Star Trek history (e.g. Kirk graduating from the Academy with his father proudly looking on).<br /><br />10) Speaking (more) of alternate histories, I applaud the decision to "reboot" the show. Just as <em>Casino Royal</em> did for the Bond franchise, it is sometimes necessary to clear the decks and start from scratch. The Star Trek timeline had grown so polluted with interpretations, inconsistencies, and conflicts that this was an almost essential move. I know many old school Trekkies were displeased (and I know some of those old school Trekkies who I know were displeased), but (don't take this the wrong way, old school Trekkies) I think there is a degree of curmudgeonly resentment, as if new Trek fans haven't "served their time" dealing with the hideous stretch polyester costumes and Shatner's bizarre speech patterns.<br /><br />9) Finally breaks the "naval combat" two-dimensionality of the Star Trek space combat scenes. Granted, <em>Star Trek II</em> had the "he only things in two dimensions" moment, but notice that the "descending Enterprise" that ambushes Kahn was settling like some sort of blimp, and not really utilizing the third dimension. Prior to this point, the only true excursion into that wacky third dimension is in the wonderful <em>All Good Things</em> wrap up to The Next Generation when the refitted Enterprise is seen "flying" 90 degrees out of plane to the Klingons.<br /><br />8) I honestly liked the blue collar villain. I know some weren't as taken, but for starters the guy looks and sounds remarkably like Kevin, one of the trainers at the gym where Erica and I work out (great guy, Kevin). But I really felt for this character -- here he is, some Romulan miner who'd rather just head home, have a few pints of Romulan Ale, and spend time with his family. Instead, an unspeakable tragedy (and a very human-like desire to focus his rage and loss on a single object) drives him mostly-mad and on a quest for vengeance that drives him the rest of the way mad. Quite a change from Christopher Plumber's wonderful Shakespeare-quoting Klingon General to have this plain-talking "Joe the Romulan Miner" character.<br /><br />7) I was very pleased to see many of the "background" members of the principle cast get stronger stories. E.g. Uhura is now portrayed as a brilliant linguist and Checkov as a math whiz. The Original Show was pioneering for including a black woman <em>and</em> a Russian in the crew. Now we can actually give them some skills. And I thought that Checkov the 17 year old math whiz was actually played relatively well as a 17 year old math whiz -- somewhat geeky but not entirely so. But then again, we live in an age when even geekdom is socially acceptable.<br /><br />6) I can't possibly express how pleased I am that the Beastie Boy's <em><a href="http://en.wikipedia.org/wiki/Sabotage_(song)">Sabotage</a></em> continues to exist in the 23rd century and to serve as an anthem for rebellious midwestern youth.<br /><br />5) Played with a lot of humor -- and a good balance of action and humor. Star Trek is not an action movie franchise, but it has always incorporated action into the stories. Primarily it has been about ingenuity and clever escapes and the power of friendship and loyalty -- something that is harder to think of and harder to execute than a good shoot-em-up sequence. All was well balanced here. And the humor was, I thought, quite wonderfully played, for Star Trek has always possessed a real wry sense of "eyebrow raising" humor. From the slapstick Dr. Strangelove homage of Kirk's "puffy hands" sequence to the generally well played "signature moment" taglines for each crew member to the dry wit of Spock, the humor was great.<br /><br />4) No Shatner. 'Nuff said.<br /><br />3) My favorite moon, <a href="http://en.wikipedia.org/wiki/Titan_(moon)">Titan</a>, played a significant role. The background shot of Jupiter in that sequence is, I presume, based on a <a href="http://www.boston.com/bigpicture/2009/04/cassinis_continued_mission.html">Cassini shot</a> that has often been my little MacBook's desktop background.<br /><br />2) in their characterization of the original actors. Some, such as Chris Pine's portrayal of Kirk, stopped short of going all the way (e.g. avoided the speech patterns). Others, such as Karl Urban's McCoy ran with the original and gave it some added depth. <br /><br />1) And the number one thing I liked about the new <em>Star Trek</em>: it breaks the "odd number curse" of the Star Trek films.<br /><br /><strong>Top five things I don't like about the new Star Trek:<br /></strong><br /><br />5) While most of the "young" characters had a pretty good physical resemblance to their "old" originals (this is starting to sound like the "New Originals" scene in <em>Spinal Tap</em>), Sulu was a pretty wide miss. It turns out (thank you Wikipedia) that John Cho (young Sulu) is Korean-American, which goes some way to explaining the differences of physical build. I'm willing to run with George Takei (old Sulu, if you are ignorant of such things) and his logic that since Sulu was stuck representing for all of Asia in TOS (and, as it would turn out, all of the GLBT community, a group for which I think Takei is one of their finest spokespeople), it was OK to show a little license there.<br /><br />4) Age, a decade or so of obscurity, and a painkiller habit have not been kind to Winona Ryder.<br /><br />3) The conceit of having most of the Federation fleet away fighting some action in some other chunk of space, thereby allowing for the convenient crew-of-academy-punks was a little convenient. But, then again, this is Star Trek and such convenient conceits seem to be a integral part of this universe.<br /><br />2) While I generally really liked the way that the technology was portrayed (generally a little clunkier than in the "later" shows, lots of warning labels, etc., I did think that there were some points where it looked like the bowls of the Enterprise had been converted into a brewery or a winery. I actually seriously think that one scene <em>was</em> shot in a winery, one of those big ones with lots of stainless steel for making low grade white wine. <br /><br />1) Just one too many of "Dammit, Jim, I'm a doctor, not a..."<br /><br /><strong>Overall?</strong><br /><br />Fifteen points in favor, five against...most of which are moderated to some degree. I'll make it easy and just come out and say that I loved it. A very well balanced film, two hours that passed quickly and have produced a lot of good musing, thinking, and discussion afterwards. Recommended, and worth the theater trip to see it in the full spectacle.

He's got a tough job at a tough time and is really taking a big bull by the horns in some of his efforts to reform the defense acquisitions process and push right-now tools out to the warfighters rather than sexy, slow to mature, high ticket programs that make for nice Popular Science covers. As a further footnote, something that he's doing that I think is absolutely brilliant is taking this agenda to the junior offices of the military. There are a lot more Lieutenants or Captains out there getting ready to lead their platoons or companies patrol somewhere in The Suck than there are queuing up for spots to fly an F-22. And while those smaller voices have a lot less individual pull than the Generals at the top, there are a <em>lot</em> of those smaller voices, and as they rotate through staff or Pentagon assignments, those voices start to wield some weight.<br /><br />But I digress from a point I have not yet started to make.<br /><br /><div style="text-align:center;"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhLhkHM4u02iFVtON1Tq9JvO-uVsPiOThgy5pU_HJxIWvqJxBWzMRfcxAWI5pLPnBJOPK0z3Wc2Ok1ySWamURQAG1KBt7qBlIn1hKXzXsdwJyRiR5wnCdkenp525BA_NmrNYro-jW4Sds9n/?imgmax=800" alt="Picture 8.jpg" border="0" width="634" height="271" /></div>This is to be about the Navy, and about naval strategy. One of Gates' favored programs is something called the Littoral Combat Ship, or LCS. Undeniably, it is sexy and dramatic vessel. A fast, agile sort of mini-warship, half Cigarette Boat, half special operations watercraft, half guided missile destroyer. It looks (and here is where I get a little mean) great on the cover of Popular Science. The LCS is a ship for the current war -- a fast and agile vessel designed to fight in close in to enemy shores, coping with "popup" threats, supporting SOF types and Marines, and clearing the way for the regular deep water navy. Peel the skin back on one and it reveals as a remarkable amount of empty space -- designed to be filled with mission kits for anti-sumbarine warfare, minehunting, inland strike, or covert operations.<br /><br />Conceptually, the LCS is clever. It is designed to offer a game changing degree of modularity, and this modularity allows for a striking range of capabilities to fit in a single hull -- without that hull getting so large that it grows unwieldy and incapable of the in-shore mission. And (perhaps more importantly these days) without having to buy enough gear to equip every hull equally. The math, at this point, seems entirely sound -- the chances of needing to simultaneously land a SEAL team, sweep for mines, and hunt submarines are pretty slim. So build a bunch of ships that <em>can't</em> do all of these things at once and just enough gear to go around, one kit per vessel. You cross-deck the sonar arrays depending on which ship is tasked with sub hunting. Cross-deck the minehunting robots to the needed ships, the special ops kit, etc. all as needed.<br /><br />The modularity carries with it a drawback -- the fact that these modules need to be changed. I mean, what if you <em>do</em> suddenly need to hunt submarines? Fine, go in to port, swap out the launching ramp and the rubber boats, and the gym and barracks for the SEALS. Load aboard the towed array sonar kit. Fly off the MH-60's that were doing the special ops work and land a couple of SH-60's to drop torpedos and do sonar dips. Let the SEALS go drink some beer and bring on board some mine warfare experts. Lather, rinse, and repeat of the mission changes again.<br /><br />Great plan, provided you have a <em>friendly port</em> nearby. And, with a bit of a flourish, the drawback to the whole LCS falls in to place. It truly <em>is</em> designed for the current war. By which I mean the Persian Gulf -- a place where it is never too far from a friendly port where it can meet up with a tender for supply and conversion between roles. Which also means, of course, that though capable on paper of some fantastic speeds, the LCS' <em>true</em> speed of deployment is limited by the rate at which logistic support can be brought over to resupply and re-role the vessel when needed.<br /><br />Now modern navy's have always depended on supply lines -- and since the US Navy perfected underway replenishment during and after World War Two, the need for friendly foreign bases has been much reduced. I fear that the LCS will only take us back a stage, back to the era of the coal fired navy when allied ports were needed every few thousand miles, ready to refill the hungry bunkers of those early, inefficient vessels. Commodore Perry, anyone?<br /><br />I am as optimistic as the next person that the Obama administration's policies will see a return towards the coalition building that dominated the war fighting of the past few decades -- when the US was working as a member (all be it a dominant one) of a team and could, therefore, pretty reliably count on friendly ports for its efforts. But even so, this reliance has its costs and risks. Does the <a href="http://en.wikipedia.org/wiki/USS_Cole_bombing">USS Cole</a> bring back any memories?<br /><br />Or, to bring up a more timely situation, what about Somalia and the shindiggery going on in the waters of East Africa? More on that later.<br /><br />Much of naval warfare is about maintaining presence. That is the thing, in this globalized world, that navies can do better than any other branch of the services. A ship can, in a way that no other weapon system can, simply <em>be</em>. It can hang out, outside the twelve mile limit and in international waters, just saying a friendly "hi." The sort of "hi" that can carry Tomahawk missiles (and therefore reach just shy of 1,000 nautical miles inland in the <a href="http://www.deagel.com/Land-Attack-Cruise-Missiles/Tactical-Tomahawk_a001146005.aspx">latest version</a>), soak up radio and radar signals and send them back home to the NSA boffins, keep track of hostile or suspect shipping. It is the very epitome of "speak softly and carry a big stick," it is the reason the phrase "gunboat diplomacy" has not been replaced with the phrase "uncrewed air vehicle diplomacy." A warship, or a collection of them, can maintain free passage of the sea lanes that carry the overwhelming majority of the world's commerce...or close them off when blockade and embargo is the order of the day.<br /><br />The United States Navy currently possess the most capable and versatile floating big sticks in the military world -- the largest fleet of (and the largest) air craft carriers in the world. There are also dozens of <a href="http://en.wikipedia.org/wiki/Ticonderoga_class_cruiser">CG-47</a> and <a href="http://en.wikipedia.org/wiki/Arleigh_Burke_class_destroyer">DDG-51</a> class cruisers and destroyers, all with exactly the sort of staying power and strike capability that I'm talking about. Boo-ya. Fly Navy.<br /><br />But these are big assets -- and many are tied up in the odd sort of self-escorting that is the devil of all deployed military operations. The cruisers are busy escorting the carriers, protecting them, tending to them. All of these vessels are also forward deployed, with their unique and amazing capabilities, around countries like North Korea that have a disturbing to just go ballistic one day (pardon the pun) or fighting the couple of active wars in which we are currently embroiled. Not a lot of these high-ticket ships are left to fill in the little cracks in US foreign policy.<br /><br />Like Somalia.<br /><br /><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj_5T94nhFBG9Ix0fdsxA-d_cK2_CagPq1fVnQvR-Iq0dy0aHNr74RRdEpZI6EKCvvU0gKZtEOhJWS_MZSyskVv1yPuz4hj7nsfDJgny7lPeL6Zf2fN6xMAbNkiiwSyuPUHLB_Nyes1enTj/?imgmax=800" alt="Picture 13.jpg" border="0" width="248" height="193" align="left" />There was once a great and noble fleet of <a href="http://en.wikipedia.org/wiki/Oliver_Hazard_Perry_class_frigate">Perry class frigates</a> (a different Perry, not the Commodore who opened up Japan), but these little and versatile ships are rapidly disappearing and now less than half of those built remain in US Navy service. Just to give you an idea of the sort of missions that these ships are tasked with, let me relate the history of one particular Perry class frigate, the <a href="http://en.wikipedia.org/wiki/USS_Nicholas_(FFG-47)">USS Nicholas</a>, during Gulf War Senior. Now I don't want you to think that I'm disrespecting the contributions of the decks launching strike missions or the cruisers launching Tomahawks. But while these "big guns" stood back and did their deeds from a distance, the Nicholas found herself:<br /><br />1) recapturing the first piece of Kuwait, an oil platform, and in the process capturing the first Iraqi prisoners of the war.<br />2) detecting and (in cooperation with a Royal Navy frigate of similar size and their embarked helicopters) sinking about a dozen Iraqi patrol boats.<br />3) rescuing a downed USAF pilot<br />4) accidentally being shot at by another USAF pilot (no harm done)<br />5) destroying several Iraqi laid mines<br />6) escorting the battleships Missouri and Wisconsin on gunfire missions.<br /><br />During much of this conflict she was operating <em>70 miles</em> closer to enemy shores than any other "regular" US Navy vessel. Since then she's kept on with the busy agenda. Read the <a href="http://en.wikipedia.org/wiki/USS_Nicholas_(FFG-47)">Wiki page</a>. Oh, and just to brag, ships that share my name have a bit of a history. If you really want a busy naval career, look at the <a href="http://en.wikipedia.org/wiki/USS_Nicholas_(DD-449)">2nd USS Nicholas</a> (the one I was just writing about was the third).<br /><br />Now here's where I get to my point -- that list of accomplishments, from Iraq to Bosnia, is a litany you will find on few vessels twice her size. It is an irony of naval history that very often the <em>big</em> ships do not get the <em>big</em> missions.<br /><br /><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi1LMrCataLv2neECNZPMrv_o7siN_Sh_sdqNWU-DDKX4bG6iGNoPyUHDsKbEZcOjH6fbxzOq1MdRdUVh1XGvmHNskplBQsvyYaXTShRDzinMO1X9Zbg_b6PSryAt0rm6C1I9iNAnwZvVlS/?imgmax=800" alt="Picture 11.jpg" border="0" width="268" height="180" align="left" />As the Perrys fade away, proving too expensive to update and too expensive to crew, the LCS' are supposed to be coming online to fill the gap. Well, the <a href="http://en.wikipedia.org/wiki/Zumwalt_class_destroyer">Zumwalt</a> is supposed to be as well -- but did anyone catch the price tag there? $3.3 billion. Yes, and perhaps more. That's the reason the big ships don't do exciting things. They cost too much. The Zumwalt is also easily the ugliest warship that anyone has ever contemplated building. Just say "no" to tumblehome, people.<br /><br />But the little ships -- the new ones, the LCS -- run the risk of simply creating <em>more</em> trouble by requiring more basing, more supply lines, and more reasons to maintain a presence in the first place. It is just a return to the problem of spending so many of your resources protecting and supporting your resources that we you have no resources left to actually <em>do</em> anything.<br /><br />Do I have a solution, or am I just a crank?<br /><br />Actually, I have a solution. At one level, this solution is simply "more Perrys." More medium sized vessels, handy enough to operate in the <a href="http://en.wikipedia.org/wiki/Littoral">littorals</a>, large enough to play a role in a deep ocean fight and to help with the escort needs of the 1st class navy (carriers, cruisers, amphibious vessels), affordable enough to be built in quantities sufficient to send them where needed, large enough to be self supporting for a reasonable length of mission. Part of what made the Perrys such versatile vessels was that they were <em>just</em> big enough to take on all sorts of odd adjuncts for their interesting missions. During her Gulf War stint, the Nicholas was carrying a Navy SH-60B helicopter, two Army OH-58D helicopters, an add-on infrared sight system (such things are now common), a kluged together minehunting sonar, and a handful of Navy SEALs to do the dirty work that occasionally came along. It had to have been a crowded ship...but it held up.<br /><br />Currently US shipbuilding is leaving this size range empty. The overly-small LCS hulls are being built, production slowly ramping up to speed. And the fugly Zumwalts are out there, somewhere, presumably striking fear and nightmares into shipyard workers forced to build them.<br /><br />So for my solution I am going to turn to the French. Yes, the French. Mocked in American military circles for so many reasons (many of which are undeserved, or at least more reasonable when explored in some depth...e.g. why did the French accumulate such a reputation for capitulation and inaction...it might have something to do with a reaction to loosing 1.4 million dead and 4.3 million wounded in World War One while pursuing a strategy of "offensive above all else"...but that is a topic for another blog). But they are a nation of increasingly competent engineering -- even if it is occasionally different in art and concept than that produced by this nation.<br /><br />The French are facing a similar problem, actually, their own need to maintain a sustained global presence. Ever since the days of de Gaulle, France has styled herself as a "mini superpower," wanting all of the trappings and abilities of the United States and the Soviet Union, all be it in miniature. And so France is one of the few countries of Europe that has always sought to maintain a global capability of power projection. This goal has not always been successful and many struggling deployments exposed weaknesses (much as the Falklands campaign exposed in the English).<br /><br />As touches mid-size naval combatants (which is the point of this now much diverted blog), France had some interesting and moderately successful experiments with not-quite-warships in the form of the <a href="http://en.wikipedia.org/wiki/Floréal_class_frigate">Floreal class</a>, an odd sort of mini-frigate with a disproportionally large helicopter hangar (actually a normal size helicopter hangar on a ship that was by conventional measure "too small" to support it). The resulting package was perfect for low-level flag showing, cooperative work, blockading, etc. But it didn't quite have the chutzpa do really rumble with the real warships and only six were built. The Floreal was <em>half</em> of what I'm looking for -- sustained presence and enforcement, but not enough warfighting.<br /><br />But facing the obsolescence of several other frigate-sized vessels, and an almost dramatically unsuccessful Franco-Enlish alliance to build an anti-aircraft destroyer, the French got together with the Italians (similar needs, if not quite of the same scale) and produced the FREMM. That stands for something, FREMM, presumably in French but possibly in Italian, that roughly means "European Multi-Mission Frigate." I have found, by the way, that French acronyms are often very nearly (and occasionally exactly) opposite the same acronym in English. So perhaps it is actually "Multi Mission European Frigate" and they kept the R from FRigate in there so it wouldn't be named "femm" which would be too close to "femme" for everyone's comfort. I'm not sure.<br /><br />The first hull of these new ships to be built for the French is to be the <em>Aquitaine</em> which is a truly beautiful word and much easier to say that "FREMM" and so, even if it is harder to type, I will hereafter call these ships the Aquitaine class.<br /><br /><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjk7Hcg9keok6Rj2JgWnu_8nIKrTilc1sBL_1fdZ1QV9XXHkQ7zqD4mh9u5YVh4TxUAbea9O_mlwVQF0oO4IJUrKMkZAbDpgnwIGee01C1lKJKzck9Ezv66iuRTnxzE2mAcsEh3bvMNp9uI/?imgmax=800" alt="Picture 12.jpg" border="0" width="472" height="331" align="left" />Now for starters, the Aquitaine is beautiful in a way that very few modern warships are. Boxy, yes, but somewhat less so than many of her peers. The long low foredeck gives a nice pointy look, not quite as Cigarette Boat as the LCS, but perhaps more evocative of the WWII era battleships and cruisers with their long gun covered bows. In a <a href="http://en.wikipedia.org/wiki/Walter_Mitty">Walter Mitty</a> sort of way, I can picture North (or South) Atlantic (or Pacific) seas dashing back as the bow buries itself in a wave, spray flying aft against the pilothouse windows (and of course, there is Commander Nick, cup of coffee in hand, standing on the heaving deck, scanning the horizon...).<br /><br />Ahem, back to my morning train ride.<br /><br />And besides, this is about naval strategy and procurement and <em>not</em> about romanticized places-I'd-rather-be...<br /><br />At this point I am going to consciously avoid the trap of rattling off a catalog of meaningless statistics about what sorts of missiles are tucked where and how many shells the gun can fire in a minute's time. Generally, these are academic details. In nutshell-land, it would break down like this, going from fore to aft:<br /><br />Gun for protection against aircraft or, even more critically, small/medium sized boats as are so often used by developing nations and terrorists.<br /><br />Bank of missiles, some anti-aircraft for self protection and some strike for targeting deep inland.<br /><br />Bundle of anti ship missiles.<br /><br />A few odd smaller guns for defense against more of the small-random-boat sort of threat.<br /><br />LOTS of decoys against missiles, torpedos, etc.<br /><br />A couple of torpedos to deal with sneaky submarines.<br /><br />A big hanger and helicopter pad for all the wonderful versatility that helicopters bring to medium-sized warships.<br /><br />Tucked away is a surprisingly competent sonar system, on par with the best in the world. I say "surprising" because anti-submarine warfare is generally out of fashion among the navies of the West -- and has been so ever since the evaporation of the Soviet threat. That sonar is an important part of why I so like the Aquitaine -- a respectful inclusion of anti-submarine capability. Right now, the US Navy is letting much of its ASW capability go. Granted, the big-bad Soviet submarine force is in decay (with a tendency to catch fire, sink, or sit on the stocks for a decade or two half completed) and their new-building programs have tended to produce more ominous news reports than completed submarines.<br /><br />But there are other threats out there, and in coastal waters a small submarine, such as those that are proliferating in the developing world, can be a potent force of ambush if well handled. And the proliferation of AIP's means that the sustained submerged endurance that was long the sole province of the nuclear navies (US, UK, France, China, Russia, and occasionally India) has spread. So another highly capable ASW hull is a (sorry Martha) Good Thing.<br /><br />There is the usual complement of radars and a very capable electronic warfare suite (that IS a lot of antennas you see). I'm not barreling into details because the exact make and model of each piece of hardware is frankly boring. The overall picture, the synergy, is what counts. And here is what that synergy is:<br /><br />A medium sized, versatile warship. One capable of providing world-class anti-sumbarine efforts from deep ocean escort to hunting diesel boats in the shallows. One capable of protecting itself from air threats and of minimally extending that protection to other vessels. One capable of projecting its sphere of influence and observation beyond the horizon (fancy way of saying "carrying a helicopter"). And, uniquely for its size, one capable of projecting the big-stick-factor several hundred miles inland, for the Scalp Naval will have capabilities not too far removed from the well known Tomahawk cruise missile. So take that persistence I've talked about and notch it up one.<br /><br />An Americanized Aquitaine would obviously show changes. Swap missiles around (out go ASTERS and Scalp Naval, in go ESSMS and TacTom). Fiddle the radars so you have guidance for the ESSMS'. Whatever. Gain a bit here, loose a bit there. I'm not <em>even</em> going to get involved in the holy war that is medium calibre gun selection. Pick your favorite. The US is gravitating towards Swedish 57mm's, the Aquitaine has an Italian 76mm. Personally, there ain't no replacement for displacement (which is NASCAR for "bigger guns are better").<br /><br />I'd (and this is a controversial one) actually not replacing the Exocet anti ship missiles with their American counterparts (a weapon called Harpoon). I'm actually only aware of a Harpoon being fired in anger twice, once in the 1980's and once in 1991's original Gulf War. Tac-Tom has a nominal moving target capability and I'd rely on that, saving a few bucks of purchase cost, hours of maintenance, and tons of displacement.<br /><br />The big helicopter deck is a crucial asset -- the no-hanger DDG-51's taught the US Navy to never again build a large combatant without helicopter capabilities. Particularly in today's small-to-medium size wars, the ability to extend the ship's horizon by anything from a few dozen to a hundred miles provides much of the reach necessary for patrolling and enforcement.<br /><br />This is, in a very real sense, a return to the role of the Frigate as it was two hundred years ago. A ship capable of holding its own in battle, of fighting amongst and supporting the larger vessels when the conflict reaches "large" size. But a ship optimized for cruising, for endurance at sea and for flexibility in employment. A ship that could support a low level conflict off the coast of a nascent African nation (my Somalia riff again) or anywhere else without requiring controversial or vulnerable ports. A ship capable of maintaining a presence, for purposes of force or policy, of acting when necessary in offense or defense, of protecting interests at sea or on land.<br /><br />Now I'm not insisting that, right now, the DoD slap down 500-600 million US$ for each of thirty or forty of these ships. I'm a blogger, and therefore have little power to actually insist <em>anything</em>. But here's how things stand -- the LCS was supposed to run about $240 million each and is currently about 100% over budget (and swelling). The Aquitaines are supposed to cost $510 million each. Given the lower technical risk of the less "game changing" design, I'd estimate the chances of cost growth on the FREMM project to be a lot less, say 20%. And the LCS bugs will get ironed out until they cost, say, $350 million each. That would allow for building roughly 32 Aquitaine class vessels for the cost of the planned 55 LCS vessels. 32 vessels with much greater staying power, versatility, adaptability, and utility. And 32 vessels that will not hamstring the navy with increased basing requirements, shorter endurances, and yet more vulnerable and expensive supply lines. Furthermore, with sufficient size, crew, endurance, and capability, the Aquitaine would free up some big DDG-51 and CG-47 vessels, allowing them to operate at somewhat reduced tempos or to focus on global crisis states such as North Korea and its nascent ballistic missile capability.<br /><br />I don't care how this is implemented. The Aquitaine is pretty and presents <em>exactly</em> the sort of blend that I think a vessel of this class needs (the strategic strike role is genius). But I do know what one of the major hurdles will be -- the submarine force. Facing the same threat of "why do we have them" as other cold war naval assets (reference above on decline of Big Red's submarine forces), the sub guys have pointed out three roles for which they are excellently suited: anti-submarine warfare, strategic strike, and special operations. These are all true -- these are <em>excellent</em> roles for a submarine. But the wonderful nuke boats are expensive to operate, a limited asset numerically, but worst of all their ace card, their stealth, denies them the ability to provide <em>presence</em>. But an Americanized Aquitaine would threaten two (actually all three) of these roles and therefore face opposition from the silent service. Well, no good idea ever went unopposed, and if Gates is willing to face down The Admirals and The Generals over some of the other elements of his agenda, perhaps he can fight this one for me. Besides, there are a lot more naval officers who are going to see surface commands (and therefore have a vested interest in a surface navy) than will ever see an undersea command.<br /><br />The result of all of this?<br /><br />Not, perhaps a <em>potential</em> game changer, but a solid and adaptable performer. Something perfectly suited to the crucial need for naval <em>presence</em> in times and places of peace, crisis, and war.<br /><br />A ship that would enable more projection, and less dependance.<br /><br />A classic frigate for the 21st century.Just Nickhttp://www.blogger.com/profile/01845987547854457407noreply@blogger.com0tag:blogger.com,1999:blog-5333608194352082143.post-74010850302278041372009-04-18T14:50:00.001-07:002009-04-18T15:37:56.777-07:00Linear Feedback Shift Registers and The Playing Card CipherSo I was looking for a name for my <a href="http://noodlebook.blogspot.com/2009/04/playing-card-cipher.html">playing card cipher that I described a few days ago</a>. I'd go with that, call it PCC for short, but that is the name of a local <a href="http://www.pccnaturalmarkets.com/">market chain</a> and therefore has already been taken.<br /><br />I'd thought of a few more. Realize, please, that ciphers often have acronym names and, particularly for not-so-serious ones like this, the name involves a degree of punning. Hence the following candidates:<br /><br />CARD: Cipher Algorithm with Randomized Deck<br />DECK: Deniable Encryption with Card-based Keystream<br /><br />Personally, I like DECK. And so DECK it shall be known as. At least for the length of this post.<br /><br />Now, after writing up the initial description, I thought it might be a good idea to expand on the underlying design and design rational. And, by way of that, to talk a little about stream cipher design.<br /><br />First off, I know that this is by no means the first attempt to produce a cipher based around playing cards. At the very least "<a href="http://www.schneier.com/solitaire.html">Solitaire</a>," developed by Real Cryptologist and crypto-guru Bruce Schneier got there first.<br /><br />But I think that my Clever Idea is the use of playing cards as indicators of binary state, therefore enabling the translation of <em>any</em> cipher into playing card form -- it is just a matter of producing one that blends simplicity and security in a way as to produce a reasonable amount of security for a reasonable amount of effort.<br /><br />For various reasons, when I was putting together DECK this "reasonableness requirement" drove me to focus on stream ciphers. In a nutshell, a stream cipher is one where the cipher mechanism operates <em>independently</em> of the plaintext. The output of this independently running stream then modifies the cipher text one bit (in the case of a binary cipher like mine) at a time. Most older stream ciphers are bit-oriented because they were intended to be implemented in dedicated hardware (military radios, bulk encryption hardware, cell phones). Many newer ones are designed to produce 8-bit bytes, 32-bit words, or other chunks of keystream all at once, as ciphers are increasingly expected to run on general purpose computing systems.<br /><br />But we're dealing with playing cards and need to keep it simple -- so a bitwise stream cipher it was to be.<br /><br />The most well understood mechanism of stream cipher design is something called a Linear Feedback Shift Register or <a href="http://en.wikipedia.org/wiki/Linear_feedback_shift_register">LSFR</a>. If you look at DECK, you will see that it has three of them -- each of the three rows of six, seven, and eleven cards constitutes an LSFR.<br /><br />An LSFR consists of a certain number of registers (each card is a register). An LSFR steps, as described in CARD, by pushing the contents of the register one to the right (from the input side to the output), discarding the rightmost bit, and using a combination of bits in the register's previous state to produce a new input bit going in to the new state.<br /><br />The input bit is produced by XOR of the contents of several specified bits in the register. If the specified bits are chosen correctly (technically they must be primitive polynomials, which is something I don't really understand, but is something I can look up <a href="http://en.wikipedia.org/wiki/Linear_feedback_shift_register#Some_polynomials_for_maximal_LFSRs">here</a> or <a href="http://www.physics.otago.ac.nz/px/research/electronics/papers/technical-reports/lfsr_table.pdf">here</a> or <a href="http://www.amazon.com/Applied-Cryptography-Protocols-Algorithms-Source/dp/0471117099">here</a>) then your LSFR will produce a sequence of output bits (based, say, on the rightmost bit of the register, the one we "discard" with each shift) that does not repeat for 2^n-1 steps (where, predictably, n is the length of the register).<br /><br />In other words, a properly designed 6-bit LSFR will produce a unique sequence of bits for 63 steps. A properly designed 7-bit LSFR will produce a unique sequence of bits for 127 steps. And a properly designed 11-bit LSFR will produce a unique combination of bits for 2,047 steps. It also means that there are 2n unique patters that each LSFR can produce.<br /><br />Now I could simply use an LSFR to produce a sequence of bits -- and indeed this approach can be used when a non-secure cipher is needed (e.g. when randomizing an electrical signal to reduce RFI or for some spread-spectrum transmission techniques). But I want to produce a <em>secure</em> cipher and for that a simple LSFR is not going to work.<br /><br />Here's why:<br /><br />A Linear Feedback Shift Register has, unsurprisingly given its name, a linear output. That means that the output of the LSFR depends in a simple and obvious way on the contents of the LSFR. If I had a simple LSFR and I recorded the output for a period of time equal to its length, then I would know what the register contents were at the point I started. <br /><br />Since an LSFR is also <em>deterministic</em>, that is to say that given the state of the register at any given time it is possible to determine the state of the register at any other time, once you know the register at one point in time any future or past output can be determined.<br /><br />A simple known-plaintext attack then makes breaking a simple LSFR child's play.<br /><br />Some complications are needed. One option is to combine a single LFSR with some sort of nonlinear stage to generate the output.<br /><br />This would mean instead of taking the keystream off the right-hand-edge of the cipher I'd do something more complex. Typically this would involve grabbing not just the end value but several values from within the register and combining them together in a more complex way.<br /><br />At first this was the approach I pursued.<br /><br />The original draft of DECK (which may yet see some life in a mildly altered form) was a 24-bit (24-card) LFSR. The reason for 24, by the way, was the purely arbitrary decision that the 16-million possible keys to a 24-bit keyspace would produce enough security for my application.<br /><br />I then developed a simple non-linear function (by flipping a coin during that epic conference call) that took four input bits from the LFSR and used them to determine a single output bit. I had the idea that which four bits in the LFSR were tapped to feed the non-linear function could be part of the keyspace and therefore increase the complexity of the cipher.<br /><br />This is inspired by a late-cold-war cipher called KEA that was used in some exportable radio equipment that was sold under various Foreign Military Sales efforts. Exact details of KEA (which I believe stands for "Kinetic Encryption Algorithm) are not known, but the variable-taps-to-non-linear-combiner idea comes from there.<br /><br />Anyhow, it turned out to be rather more difficult to keep track of those 24 cards, stepping all of them every round, then I expected. And, while I'm sure I'd eventually have memorized it, I kept having to consult a table written on a sticky note ("Stick Together!") to produce the output bit.<br /><br />This lead to a phase of introspection and review. There is, fortunately, <em>another</em> way to generate a less-guessable output from a LFSR. This involves combining the output of several registers together. Several registers with regular stepping can be mixed by a non-linear function, as is done in the <a href="http://en.wikipedia.org/wiki/E0_(cipher)">E0</a> cipher used in Bluetooth devices.<br /><br />While this might break up the stepping from one titanic effort of 24 cards at a time, I'd still be dealing with some sort of memorized nonlinear function (and the one in E0 is a bear, so I'd have to simplify it a lot for my purposes).<br /><br />Another approach for adding nonlinearity to cipher consisting of several LFSR's is to step them irregularly but combine them simply. This is done in a lot of simple (and theoretical) bitstream ciphers. Read Applied Cryptography to read about them. This is also the approach taken by A5/1, the much mocked GSM cipher.<br /><br />A5/1 isn't really mocked so much as it is broken. Which, in cryptanalytic circles, is the same thing. It has several known flaws and a sufficiently small keyspace as to make them practical for exploitation. But before we get all cranky about it, let's remember that A5/1 was developed in 1987 -- 22 years ago, an eternity in cipher years and was, if you buy the conspiracy theories, deliberately kept somewhat weak at the request of European police and security agencies. Though much of that intentional weakening is in the key setup, which is out of scope for this discussion.<br /><br />Despite this, I've always found A5/1 to be a very pleasing cipher. Let's take a look at it:<br /><br /><div style="text-align:center;"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEikhqy_mdv_fBXD3rfqhtmVCeot6uRNZKmwrU4DFZQ_Sty5jljjJXWQ1nXK5JP_HF7BSP4LCwCq8EeljdRaA5KJTblemkwSG260AH1KXP-G8LYbDN40tx2l1YrlA42jYzhdeLXN6sipzuYq/?imgmax=800" alt="Picture 11.jpg" border="0" width="398" height="140" /></div><br /><br />Note that Wikipedia has very much more attractive illustration of A5/1 <a href="http://en.wikipedia.org/wiki/File:A5-1.png">here</a> but the diagram runs from RIGHT-to-LEFT, the reverse of all of my other descriptions. My brain must work from left-to-right, the opposite of French cryptologists (A5/1 is French). So I found this image, which I pwned, but since I got it from a ppt about breaking A5/1, I don't feel too naughty. <br /><br />If you think back to the <a href="http://noodlebook.blogspot.com/2009/04/playing-card-cipher.html">description of DECK</a>, you may already see similarities. Note the three LFSR's: upper, middle, and lower. The plus-in-a-circle stands for XOR, so you may be able to figure out the three feedback lines, one for each register. The upper and bottom are tapped in four places, the central one in two places. The output is generated by simply XOR'ing the rightmost bits of each of the three registers.<br /><br />None of this is fancy -- and in fact none of it is particularly secure. Where A5/1 gets interesting is how it clocks the three registers. Look at the three center(ish) bits, C1, C2, and C3. Just like DECK, A5/1 clocks whichever registers have the same value as the majority of the center bits. Two or three registers clock.<br /><br />What drew me to this construction is that 3/4 of the time, only two registers have to clock. So, when it comes time to flip the playing cards, instead of having to deal with 24 of them every round, there is a chance that our DECK-using agent will only have to flip 13, 17 or 18 cards. On average, that means flipping 18 cards. Labor saving!<br /><br />To get the numbers down, for DECK, I reduced the contents of all three registers. I also changed the feedback polynomials and tapped all three registers at only two places each. Both have a negative security impact, I'm sure, but also simplify the user's job. The fact that the taps for the shorter two registers work out to the last two positions helps. So the only extra number that needs to be memorized is that the long register taps at the 9th and final spots.<br /><br />So that is, roughly put, the evolution of DECK. All of the other discussion points of developing a good binary language that were mentioned in the original posting apply.<br /><br />Now I'm still playing with this playing-card-cipher idea. I still hold out some potential for the single-register version. I also have some thoughts about a "short but wide" cipher that uses five bit values for each stage of the shift register, thereby producing enough output to encipher one "letter" worth of information at a time.<br /><br />I also wonder if there would be a way to mix a couple of techniques to produce "reasonable" security with greater convenience. Perhaps a fixed permutation (shuffling but not flipping) of a set number of bits at a time (probably five) combined with a more simply generated keystream. This might vaguely resemble Phillip Rogaway's <a href="http://www.cs.ucdavis.edu/~rogaway/ocb/">OCB</a> block cipher construction which I'm rather partial to (and not just because he's a prof at Davis, my home town). The permutation could be keyed but constant across a given message. Not sure about the security implications of that, or how much additional convenience it would give.<br /><br />More musings...likely...<br /><br />It would get away from the genesis of DECK, which was to use playing cards to implement well understood modern cipher techniques. But hey, its all in fun anyway, isn't it?Just Nickhttp://www.blogger.com/profile/01845987547854457407noreply@blogger.com0tag:blogger.com,1999:blog-5333608194352082143.post-66967732396249097312009-04-16T21:39:00.001-07:002009-04-18T14:52:57.935-07:00The Playing Card Cipher<div>UPDATE: I have added an expanded discussion of the thought process behind this cipher and some of the underlying technologies: <a href="http://noodlebook.blogspot.com/2009/04/linear-feedback-shift-registers-and.html">Linear Feedback Shift Registers and the Playing Card Cipher</a>. Happy reading!</div><div><br /></div>The following post describes a cipher, one with a few unusual properties. First off, it is not intended to be implemented with any of the usual technologies of computers, custom integrated circuits, or even electro-mechanical rotors. <br /><br />It is intended to be implemented with playing cards.<br /><br />It was born during an epic conference call (the total call ran to 14 hours, though my role it it lasted just around 12) when I occasionally found myself with little to do but listen and wait for an opportunity to contribute. It proceeded to evolve over several days of tweaking and (I hope) improvement until finally reaching the form I outline below.<br /><br />In addition to the unusual form of implementation, this cipher was constrained by some equally unique requirements:<br /><br />1) It should be possible to implement it using the technology of the 17th century.<br /><br />2) It should require no tools or objects that could arouse suspicion.<br /><br />3) Ideally, it should be easy to "hide" efforts at using the cipher if discovered<br /><br />4) It should be possible for a person of slightly above average intelligence, if taught and given opportunity to practice, to implement the cipher from memory.<br /><br />5) It should possess sufficient security for the times.<br /><br /><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjcZIW0rriCGoIfmBanxhf20OEI0o7AytC3zAwsU27eDW9lTwu9WelOIsMlVQGPCe6SowKWGzviwMPyeAqDwWFL1PbeBMLPnQ1mExwWR7WkbvxkNoK3rVuJQGCxKF7q2f24XQ8Fx9hip590/?imgmax=800" alt="Picture 1.jpg" border="0" width="196" height="293" align="left" />The inspiration was the cryptographic subplots of Neal Stephenson's <em>Baroque Cycle</em> and, in particular, the exploits of spy/courtesan Eliza. I'd also recently discovered Sony's very elegant <a href="http://www.sony.net/Products/cryptography/clefia/about/index.html">Clefia cipher</a> and found myself in a crypto-mood.<br /><br />Not being a cryptographer, but rather a <em>fan</em> of cryptography, I chose to base this cipher on a fairly well know and reasonably simple href="http://en.wikipedia.org/wiki/Stream_cipher">stream cipher. For various technical reasons related to complexity of implementation, I chose a stream cipher rather than the more complex (but potentially more secure) block cipher approach.<br /><br />My basis was <a href="http://en.wikipedia.org/wiki/A5/1">A5/1</a>, the cipher used to encrypt voice channels in GSM telephones. A5/1 is pretty broadly regarded as completely broken, but is well described and gloriously simple. I simplified it more. And, I'd like to mention, <em>broken</em> has very different meanings in 2009 and 1779. Rather than getting into a lot of design theory and the evolution (which I think <em>is</em> rather interesting...) let's dive in to the beast itself.<br /><br />I will assume that before producing the cipher that the message to be enciphered has been translated into some sort of binary notation. There is some discussion of this later, but it could be as simple as saying that the pattern 00001 = A, 00010 = B, 00011 = C, 00100 = D, etc. at five bits per character.<br /><br />But now here is now the cipher works...<br /><br />Throughout the following, I use the notation that face <em>up</em> cards have the binary value of 1 and face <em>down</em> cards the binary value of 0. The entire cipher is, then, implemented using playing cards in place of binary registers.<br /><br />Lay out three rows of cards.<br /><br />The uppermost has (in this version of the cipher) six cards, the next seven cards, and the bottom row eleven cards. I find it easy to "right justify" these rows so that the rightmost cards are all aligned vertically. These three rows constitute the shift registers of the cipher. The leftmost card in each row constitutes the "first" position in that shift register and the rightmost the "last." Binary values will migrate from left to right across each shift register. Face up cards represent binary "1" values and face down cards represent binary "2" values. The arrangement of up and down cards constitutes the initial key of the cipher.<br /><br />With this arrangement, there are 24 cards, equivalent to a keyspace of 24 bits. Paltry by modern security standards, but remember that we are doing this with playing cards! The intent here is to produce a cipher using modern design concepts but that an 18th century spy could have implemented. Note that I do not specify the method of "keying" the cipher. I have some speculations on that later, but suffice it to say that some scheme for inputting the initial pattern of cards is essential -- and that the decoder be able to produce the <em>same</em> initial state.<br /><br />To the left of each row of cards, place a single card. This card is not actually part of the keyspace, but is used as a mnemonic to store the new first value before it is fed into the register.<br /><br />It may also be helpful to place a few markers on the layout to facilitate the stepping of the cipher. The actual marker is up to the individual depending on circumstances of availability, epoch, cover story, personal preference, etc. Think poker chip, other card, pretzel, pen, Post-It note, etc (I used matches because they were handy). Each marker should be set above or below the designated card so that it does not interfere with the manipulation of the card. It will also help to have two different types of markers. Use the first kind, which we will call red, to mark the last (right-most) two cards of the upper two rows (cards 5 and 6 of the upper and cards 6 and 7 of the lower) as well as the last and next-to-las (cards 9 and 11) of the last row. Note that in the illustrations I used matches placed <em>below</em> the indicated cards. Then use the second kind of mark, which we will call black, to mark the 3rd, 4th, and 8th cards in the top, middle, and bottom rows respectively. Note that these cards should all lie in a vertical column if the layout was set up as I suggest. Here I simply placed a pair of matches at the top and bottom of this column.<br /><br />Now begins the process of "stepping" the cipher and generating the output.<br /><br />The cipher executes through a series of "rounds," each of which produces one bit of output. Each row consists of three phases (this is starting to sound like some <a href="http://en.wikipedia.org/wiki/German_style_game">German style board game</a>, isn't it?).<br /><br />Phase One<br /><br />During the first phase we produce one bit (one binary value) of cipher output.<br /><br />Look at the last (rightmost) cards. If there is an even number of 1 (face up) cards then the cipher outputs a 0. If there is an odd number of 1 cards, then the cipher outputs a 1. Note that zero is an even number. Technically this mathematical function is called an <a href="http://en.wikipedia.org/wiki/Xor">XOR</a> and is a very big deal in modern cipher design.<br /><br />This output (called the keystream) will be combined with the plaintext message bit-by-bit using the same function. If the plaintext and the keystream are both 1's or both 0's, then the ciphertext is a 0. If <em>either</em> the plaintext <em>or</em> the keystream is a 1, then the ciphertext is a 1.<br /><br />Phase Two<br /><br />Now we need to step the cipher forward to prepare for the next round. Look at each row's red highlighted spaces (5th and 6th, 6th and 7th, or 9th and 11th). Based on the values in these spots, we will select the <em>new</em> first value of that row. The extra cards laid to the left of the cipher spaces will serve as memory aids in this process.<br /><br />Again, use an XOR. If the two highlighted spaces are both 1 or both 0, the extra card sets to 0. If exactly one of the highlighted spaces is 1, then the extra card sets to 1.<br /><br />Phase Three<br /><br />Finally we will actually step the cipher forward. This is the most time-consuming step in the process and actually involves two sub-phases.<br /><br />In the first sub-phase we decide which rows will step. The result will either be two or three. Look at the black highlighted column. Based on the three cards in this column, either 1's or 0's will have a majority. If 1's have the majority, step whichever rows have 1's in this column. If 0's have the majority, step whichever rows have 0's in this column.<br /><br />For example, if the top most row has a 0 in the black highlighted column, the middle row has a 1, and the bottom row has a 1, then the bottom two rows would step and the upper row would remain unchanged for this round.<br /><br />Note that if all three cards are the same then all three rows step.<br /><br />To actually step each row, simply start with the right most card and set it to the value of the card immediately to its left. This means that the rightmost value is lost and the "new" value is fed in from the extra cards that we set up in step two.<br /><br />That's it.<br /><br />That whole process produces one bit of output. It takes (about) five of those to encipher one letter.<br /><br />Back then, people had a lot more time.<br /><br />A few notes:<br /><br />To decipher, simply start with the same initial setup and repeat this process. The beauty of the XOR is that it is self-reversing. XOR plaintext and keystream together to produce cipher text. XOR cipher text with keystream and the plain text magically reappears.<br /><br />The use of the cards to represent bits by face up/down state removes any dependancy on the particular variety of card deck in use (such things have not always been as standardized as they are today). One could use Tarot cards, for example.<br /><br />It may be helpful to run the cipher for some time while noting down the output on a piece of paper and then doing the xor to transform the plaintext into the cipher text. I use the extra cards of the deck to store a batch of output, stacking them face up or face down depending on each step's output.<br /><br />I make no effort to define the method of key setup. Any of several strings of numbers could be used, sourced in any of several ways. Information from a newspaper, translated into binary could be used. It would, in any case, be very advisable to run the cipher a cycle or two to mix in the new key before starting to actually use the output.<br /><br />I also make no guarantees of security. Let's face it, this was developed based on a flawed and broken cipher with modifications performed by a guy with little mathematical understanding of cryptology beyond the most shallow and conceptual level (that's me). The value here is purely as an exercise, a game, and a period piece.<br /><br />One of the obvioius sources of tedium in this cipher is the inefficiency of binary for sending information. Versatile, yes, but it takes more than five symbols to represent the same amount of information contained in one english letter. A carefully chosen scheme for representing the text (assuming the message is in text) in binary is therefore important. Obviously ASCII with its irritatingly liesurely 8-bits per character pace is out, since there is no need to represent upper, lower, and a whole host of wacky special symbols.<br /><br />Instead, since this is for secret communication, pare down to the minimums.<br /><br />For starters, I suggest a five-bit code that would allow for the sending of 32 characters. Beyond the basic 26, the extras could represent common words or phrases, punctuation, or a shift character to swap to a different binary alphabet for numbers.<br /><br />Six-bit characters would allow for the representation of all the numbers even more cleanly and then some (probably a short hand for common words and phrases) since it would allow for 64 possible values. Keep in mind that this binary alphabet must be memorizable.<br /><br />This is a whole separate discussion, but there are countless options for optimizing the encoding process. A Huffman code is another option, of course, but I have not had the opportunity to see how effective of a Huffman code I can build and if it ends up as more effective than the shorthand I propose above.<br /><br />To conclude, here is a basic example:<br /><br />I wish to encode the message "GOOD NIGHT."<br /><br />I encode this message using this simple binary code:<br /><br /><span class="Apple-style-span" style="font-family:'courier new';">A: 00001<br />B: 00010<br />C: 00011<br />D: 00100<br />E: 00101<br />F: 00110<br />G: 00111<br />H: 01000<br />I: 01001<br />J: 01010<br />K: 01011<br />L: 01100<br />M: 01101<br />N: 01110<br />O: 01111<br />P: 10000<br />Q: 10001<br />R: 10010<br />S: 10011<br />T: 10100<br />U: 10101<br />V: 10110<br />W: 10111<br />X: 11000<br />Y: 11001<br />Z: 11010<br />Space: 11011<br />Period: 11100</span><br /><br />I get:<br /><br /><span class="Apple-style-span" style="font-family:'courier new';">00111 01111 01111 00100 11011 01110 01001 00111 01000 10100</span><br /><br />I will key my cipher with the day's close of the Jow Jones Industrials which happened to be 8125.43 today (not bad, by today's standards!). Since that won't give me quite enough digits, I will concatenate it with the absolute value of the day's change, 95.81. I will ignore any 0's or 9's that come up and encode these digits in a simple three-bit binary where:<br /><br /><span class="Apple-style-span" style="font-family:'courier new';">1: 000<br />2: 001<br />3: 010<br />4: 011<br />5: 100<br />6: 101<br />7: 110<br />8: 111</span><br /><br />This set of digits 8125439581 sets my key as:<br /><br /><span class="Apple-style-span" style="font-family:'courier new';">111 000 001 100 011 010 100 111 000</span><br /><br />I actually have extra, so I won't end up using the last three bits. The rest I put into the cipher, starting at the upper left and loading the three rows from left to right, top to bottom. The starting position is, then:<br /><br /><span class="Apple-style-span" style="font-family:'courier new';"> X 111000<br /> B RR<br /> X 0011000<br /> B RR<br />X 11010100111<br /> BR R</span><br /><br />Note the highlighted spots in the rows.<br /><br />The first step of the cipher produces a "1" as output since the rightmost spots have two 0's and a 1.<br /><br />The intermediate phase of this step sets the extra cards (initially shown as X's) to 0, 0, 0.<br /><br /><span class="Apple-style-span" style="font-family:'courier new';"> O 111000<br /> B RR<br /> O 0011000<br /> B RR<br />O 11010100111<br /> BR R</span><br /><br />Since the upper and middle rows both have 1's in the black highlighted space, they step forward, producing this:<br /><br /><span class="Apple-style-span" style="font-family:'courier new';"> 0 011100<br /> B RR<br /> 0 0001100<br /> B RR<br />0 11010100111<br /> BR R</span><br /><br />The next step produces another 1 for output (which will, either now or later, be XOR'd with the 2nd bit of the plaintext just as the first output was with the 1st bit of the plaintext).<br /><br />The cipher then advances:<br /><br /><span class="Apple-style-span" style="font-family:'courier new';"> 0 001110<br /> B RR<br /> 0 0000110<br /> B RR<br />0 11010100111<br /> BR R</span><br /><br />The third step produces another 1 and the cipher advances:<br /><br /><span class="Apple-style-span" style="font-family:'courier new';"> 1 001110<br /> B RR<br /> 1 1000011<br /> B RR<br />0 01101010011<br /> BR R</span><br /><br />It produces a 0 and advances...<br /><br />And so on and so on.<br /><br />Enjoy. Use it -- with due warnings of security. If you <em>are</em> a 17th century secret agent, please let me know. If you find this interesting, please do so as well. I have done much thinking on this topic and hope to do more.<br /><br />Oh yes, and it needs a name...I'm working on that. Perhaps at the next conference call?Just Nickhttp://www.blogger.com/profile/01845987547854457407noreply@blogger.com0tag:blogger.com,1999:blog-5333608194352082143.post-86694288122199971382009-03-25T08:41:00.001-07:002009-03-25T08:41:54.840-07:00AnathemThis blog entry was conceived as a review of Neal Stephenson's new novel <em>Anathem</em>. I say that because half way through you may think that you've wandered into a discussion of the phenomena known as the "<a href="http://en.wikipedia.org/wiki/Sense_of_wonder">sense of wonder</a>" by science fiction pundits, my own personal thoughts on the motivations that keep us reading a given book, my equally personal thoughts about writing and authorship, and the scientific and philosophical viewpoints of <a href="http://en.wikipedia.org/wiki/Roger_Penrose">Roger Penrose</a>. Despite this potential perceived digression, this entry <em>remains</em> a discussion of <em>Anathem</em> -- and of the train of emotional and philosophical musings that book set into action.<br /><br />And this brief introductory paragraph serves, also, as an example of something that <em>Anathem</em> lacked -- perhaps inevitably so. More on that later.<br /><br />Back to the book. And beware, that spoilers are going to occur. Not plot description spoilers. If you want those, google "Anathem" or just go to the book's <a href="http://en.wikipedia.org/wiki/Anathem">Wikipedia page</a> which contains a passable plot summary. My spoilers will be more in the way of indirect references to the events and concepts in the book.<br /><br /><em>Anathem</em> is a book that I believe all science fiction authors are drawn to, at some point in their careers, write. Some get to it right away, others dance around the topic for decades. For Stephenson, known for his near-term post-cyberpunk and historical fiction, this was not the most obvious direction for his writing to take. But, as I said, it is an almost inevitable draw.<br /><br />A draw to what? <br /><br />To first contact.<br /><br />To the first meeting of two races, peoples, biologies, civilizations, or whatever. Sometimes it is humans and bug-eyed monsters, sometimes long lost worlds, or any of a thousand other variations. But the thought of meeting life from <em>elsewhere</em> is an endemic and driving force among us who read, write, or think about science fiction. The reasons should be obvious, and so not need themselves be explored.<br /><br /><em>Anathem</em> also reminds me fiercely of one of my absolute personal favorite books, Umberto Eco's masterful <em>The Name of the Rose</em> (if you want a more detailed discussion, and some backstory on my reading tastes, please check out my <a href="http://noodlebook.blogspot.com/2008/08/desert-island-books.html">Desert Island Books</a> post). Some similarities are almost immediately obvious. Both books are set in monasteries (of a sort). Both feature first person narratives written, ostensibly, as journals by monks living within said monasteries-of-a-sort. Both involve sub-plots investigating the relationship between cloistered and secular life. Both possess complex stories with interwoven plots and gradually unfolding layers of mystery. And both possess patient pacing that slowly build from a sedentary opening to a violent climax.<br /><br />There is something interesting in this pacing, for both books, so methodical and conversational and almost plodding. Some books are page-turners. Each page, each scene, each chapter throws something new and electrifying, drawing you onward and onward toward the finish. But some books require tolerance and devotion to finish. They draw you on more subtly and more provocatively: there may be tedious periods of exposition to endure, plot twists to absorb, obtuse narrative to decipher. What keeps us reading, then?<br /><br />Remember, I promised you this diversion!<br /><br />I posit that there are four <em>good</em> reasons that keep us reading a book. There are also some less sophisticated (or less healthy) motivations -- bull-headedness, peer pressure, assignments, etc. But as for the reasons that are worth our discussion:<br /><br /><strong>Excitement:</strong> This is perhaps the "simplest" reason. The book is compelling by virtue of what happens. The scenes are graphic and fast paced and transporting, by virtue of the moment-to-moment action, to another time and place. Movies do this easily and do it well, and books can muster the same sense of excitement and urgency when the fur is flying. But what if, as happens in the opening scenes of both <em>Anathem</em> and <em>The Name of the Rose</em>, the excitement just isn't there, replaced with philosophical musing or detailed backstory?<br /><br /><strong>Mystery:</strong> We humans, at least those of us who enjoy science fiction, are inevitable lovers of mysteries. We want to <em>know</em> and <em>understand</em> what is going on. If we are faced with an puzzle we want to know the solution. It does not matter if the puzzle is complex (what is up with the machinations of the evil warlord?), simple (who killed the monk?), or very complex (what is the very nature of space-time?), we want an answer. Note -- one of those three is from <em>The Name of the Rose</em>, one from <em>Anathem</em>, and the warlord thing I totally made up. A book that poses a sufficiently interesting mystery -- and keeps us interested and following along with clues on the way -- can maintain interest as surely as one that as a rolling series of smack-down fight scenes. Note that I do not just mean mysteries in the sense of an episode of <em>CSI</em> or <em>Matlock</em>, but also the more general sense of "an unknown" that beckons exploration.<br /><br /><strong>Threat:</strong> Once we are invested in a character or characters, we want to know that they are OK. If there is a threat of danger -- of death or injury or banishment or whatever other peril is appropriate -- we will keep reading to make sure that threat passes or is defeated. Naturally, threats and mysteries can interweave -- and good bit of excitement can be built up while illustrating the threat. And should be, since a threat must feel real to the reader, just as it does to the characters. And us fickle readers need reminding, every so often, of what perils are out there.<br /><br /><strong>Sense of Wonder:</strong> Finally we get to the somewhat cryptic "sense of wonder." This is a term often used in science fiction and fantasy circles to refer to that wonderful moment in a book (or movie) when the reader/audience suddenly realizes that "It looks like we're not in Kansas any more." And there you have it -- one of cinema's most well known "sense of wonder" moments. Another inevitable classic is "That's no moon, that's a space station." Got it?<br /><br />"Sense of wonder" moments (which I will henceforth call "moments of wonder") nicely pair with mysteries. Think "Jurassic Park": where are we, what is going on? Cut to Laura Dern's reaction shot (and John Williams' rather cliche score) as she sees the grazing dinosaurs. Sometimes (like Jurassic Park) the moment of wonder hits us with the grace of a sledgehammer. Sometimes it creeps in more gently (if you haven't seen <em><a href="http://en.wikipedia.org/wiki/Jacob's_Ladder_(film)">Jacob's Ladder</a></em>, do so, but do so early in the day in a well lighted room while surrounded by a group of close friends who will accompany you everywhere you go for the next 96 hours).<br /><br />Sense of wonder is a powerful thing. It is in so many ways the opposite of a mystery -- it is a moment of revelation and often explanation. But if done right it is also a moment that opens up even further moments of mystery and wonder -- and that does so by playing on our sense of curiosity and desire to explore the unknown.<br /><br />Now back to <em>The Name of the Rose</em>, <em>Anathem</em>, and a third book, <em>Jonathan Strange and Mr. Norrell</em>, Susanna Clark's wonderful and fantastic (archaic and modern meanings of both words, please) alternative history that truly deserves a review of its own but must be patient and enjoy this brief appearance in a supporting role. All three are books with (depending on your viewpoint) charmingly or lumberingly methodical paces. All three are books that occasionally "go off" on tangents that seem, at the time, of little or no importance. All three rely, then, on some degree of Mystery, Threat, or Sense-of-Wonder to keep the reader going. <br /><br /><em>The Name of the Rose</em> opens with a mystery -- a dead monk. That alone is interesting and good for a few pages. But when monks continue to die, that mystery deepens. New ones are added as the heroes pursue the responsible party. The inquisition is about to show up, and things are going to get ugly (add Threat). Someone soon tries to eliminate the nosy investigators...more threat... Eco even manages to work in a few Moments-of-Wonder, taking advantage of the 14th century setting. In the end, the sometimes tedious slog through the boring bits proves worth it -- for only by accepting and learning from the philosophical debates and discussions can the motivations behind the crimes truly be understood.<br /><br /><em>Jonathan Strange and Mr. Norrell</em> relies much more on a sense of wonder, of a dreamy floating journey through an alternate and magic-infused England. The book leans on willfully archaic language and a Jane Austen look-and-feel that is interrupted by moments of wonder and magic to propel the reader along like a punt along the Thames (and that really is the image I have in mind). There is also threat -- the brooding malevolence of "The Gentleman with the Thistledown Hair" and the foreshadowing of Clark's many footnotes. <br /><br /><em>Anathem</em> is at least as needing of such invigorating motivations as the other books. Perhaps even more so, since its first 500 pages include a free lesson on physics and metaphysics. Normally, the chance to learn is more than enough to keep me reading. And Stephenson, I want to say clearly and loudly, is a brilliant teacher. If he wrote a non-fiction physics textbook I'd buy it in a second and probably read it twenty times. Some of my favorite moments in <em>The Diamond Age</em> are the allegorical tales from The Young Lady's Illustrated Primer. Stephenson works analogy as an instructional tool like no one I have ever read, heard, or known (and this is an area in which I am no slouch myself). And the educational moments in <em>Anathem</em> are as fine as any he has ever written. <br /><br />There are just too many of them.<br /><br />When setting a book in a monastery, even one located on an alien world, it is all too easy to fall into the trap of making every scene a dialog between two characters. That is, after all, a large part of what appears to take place in the cloistered world. Discussion. Teaching. Debate. Musing. You can muse with total focus, muse while pruning grapes, muse while eating, muse while perming penance, muse while participating in rites and rituals. And Anathem pretty much works all of these possible musing-settings. <br /><br />Until I, for one, was pretty well mused out. Because, you see, these wonderfully clear moments of instruction and debate were not discussing the Earthly science and philosophy that I know. They were discussing that of Arbe, the world on which the book is set. Yes, Stephenson has the audacity to teach cosmology, physics, orbital dynamics, configuration space mathematics, cognitive psychology, and a fair bit of <em>meta</em>physics all while using about 50% made up words. This is what finally got me to the hands-in-the-air point of frustration. How was I to know if a given passage, which I found interesting, was something that I could bring up in conversation with a reasonably well educated and intelligent person and have a reasonable chance that they'd know what I was talking about?<br /><br />Now don't get me wrong -- Stephenson wasn't making this shit up. It was all dead-to-right academically derived thinking -- mostly that of fox (and not hedgehog) <a href="http://en.wikipedia.org/wiki/Roger_Penrose">Roger Penrose</a>. But just <em>enough</em> of it was changed that I knew it was different. So why, I kept asking myself, should I invest the energy necessary to put all of this together when it is only good within the context of this <em>one</em> novel (all be it a long novel)? If I wanted to take any of my knowledge home with me, if I wanted any of that <em>transfer</em> that us adult educators crow about so much, I'd have to build a key translating terms, concepts, and theoreticians between the lingo of Arbe and that of 21st century Earth.<br /><br />Finally, of course, I did reach the throw-my-hands-up point. I didn't literally throw them up, but I began reading a little faster. I'd go into turbo mode -- skim whole pages at one glance looking to see if things had moved on. If they hadn't, I'd kick it forward another page and repeat until I saw some variety.<br /><br />This was, I know, a morally reprehensible way of acting. But for someone with a family, a career, a house to take care of, and the crowing distractions of Google and Wikipedia present at every turn, sometimes those precious thirty or forty five minutes on the train or in bed at the end of the day feel so oppressively short that the relentless push of the clock forces us to do things we don't want to. Like skip ahead a few pages. And because of this, I know I must accept some of the blame for what follows. But some of that blame must fold back onto the author. For if the traveler is lost, it may not be that they didn't read the map, but that the map is unreadable.<br /><br />What Stephenson seems to have expected would keep us going was the Sense of Wonder. Anathem is full of little moments where the differences between Arbe and Earth, and the interesting complexities of Arbe's civilization, show up. Each of these was a little kick in the backside, a boost good for a few more pages. There was also threat, brooding, quiet, indistinct, and all together insufficiently threatening. For the first few hundred pages. <br /><br />Things do start to stiffen up, a little, as the book moves on but it really isn't until almost page three hundred that we start to get the good payoffs. The possibility of aliens. But we still have to noodle around another two hundred or so for things to get concrete and solid and the threat to, rather slowly, materialize. Namely, that the alines Might Not Be Nice.<br /><br />By that point, however, things have gotten good and solid and there is less and less time to dawdle around with tedious discussions about science and philosophy using made up words. Instead, we have migrated into a pretty good aliens vs. humans (except that the humans aren't <em>really</em> humans, but rather residents of the planet Arbe, and some of the aliens, as we eventually learn, are humans) story. It kept vaguely reminding me of the old Niven/Pournelle book <em>Footfall</em>.<br /><br />You know the schtick, an overwhelmingly powerful but aloof force is defeated by the element of surprise and cleverness by scrappy not-quite-humans. It was well implemented, and involved a few clever tricks. An almost excessively detailed deviation into orbital dynamics was part of it. And the quantum fuzziness of the multiple-worlds-theory that was so pervasive an object of discussion throughout the rest of the book kept cropping up and providing a waking-dream level of what-narrative-do-I-trust interest.<br /><br />It was good, quite good. It was compelling and page turning, devoid of excessive musing and discussion. A great deal of conspiracy, potential conspiracy, and just plain confusion kept every one guessing. And it ended with a gratifying tightness and evenness of pace that is wildly out of character for Stephenson. But it wasn't quite worth the investment that I perceived as expected of me, the reader, through the first few hundred pages.<br /><br />The interesting thing, in retrospect, is that if I <em>had</em> stuck through it and gotten full value out of Stephenson's education in the first 500 pages, I would have found the payoff in the second half of the book, and in particular over the last 150 pages, much more compelling. Instead of a "decent aliens vs. not-quite-humans story" it would have been a much more clever, tightly woven, and possibly even slightly profound aliens vs. not-quite-humans story.<br /><br />So there is a lesson here, regarding the path we take when the map is nearly unreadable. Sometimes it is, perhaps, intentionally so, and the wandering journey is part of the experience. So with that said, I look forward to re-reading <em>Anathem</em> the next time I truly have a Great Deal of time to kill. I might pursue the audiobook, since that format is much less conducive to "yeah-whatever" fits of page turning. Audible has one, though it appears to be a full-cast recording and I am rather notorious for disliking full-cast recordings.<br /><br />It is also interesting to note that my immediate reaction, after finishing <em>Anathem</em> was not to foreswear Stephenson as a tedious hack and to run away from any of the ideas that he was considering. No, instead I went and started googling those scientists, philosophers, and scientist/philosophers that clearly influenced the book. And, on my way out the door the following morning, I grabbed <em>Quicksilver</em>, book one of his vast "Baroque Cycle" trilogy. I'd started Quicksilver some time ago, and recalled liking it, but had put it down (as it turns out, based on a receipt from Bouchon that I found pressed into service as a bookmark, the interrupting factor was returning home after a few days vacation).<br /><br />As I read through Wikis about Roger Penrose and his ideas I kept having retroactive "moments of wonder" -- points where I would flash back to some element in the fast paced final few hundred pages of <em>Anathem</em> and suddenly <em>get</em> it. Understand how it fit into the tangled web that Stephenson had been weaving over those first 500-700 pages. And that is why I now realize that, had I been more patient and methodical (and had Stephenson thrown me some more breadcrumbs to keep the motivation alive), the whole thing might have been much more worth the wait.Just Nickhttp://www.blogger.com/profile/01845987547854457407noreply@blogger.com0tag:blogger.com,1999:blog-5333608194352082143.post-49290468427049942952009-02-05T12:00:00.001-08:002009-02-05T12:15:25.636-08:00Captain CollectedSo I assume you've all been listening to Christian Bale's <a href="http://www.aolcdn.com/tmz_audio/020209_christianbale.mp3">much publicized rant</a> against the director of photography on the new Terminator movie. I think that, in addition to betraying a certain lack of impulse control, it may indicate a lack of understanding about how movies are made. Let me lay it out for you, Mr. Bale.<br /><br />You see, there are these things called <em>cameras</em> that you might have heard of. They, together with those bright, glowing objects called <em>lights</em> are under the control of a man called, variously, the cinematographer or director of photography. The important thing to realize, Mr. Bale, is that this is not a live stage play. The audience doesn't see you in all your glory. They see pictures. Pictures that the DP takes. So, you see, it is best to treat him with respect. Unless you want to find your nose hair the best lit and in-focus part of a close up, one day.<br /><br />Now the DP didn't walk into the shot and spoil a take. He walked around in the background. Perhaps it was a slack-ass move on his part, perhaps he was trying to get the next shot set up so that Mr. Bale wouldn't have to wait or the movie could stay on time or within budget. Who knows.<br /><br />Today I found another piece of audio. Now you all know that I since the events of US Airways flight 1549, I (along with the rest of the aviation community) have been doing everything possible to hallow Captain Sullenberger and his crew. Well, here is another way to do so: compare temperaments between Capt. Sullenberger and Mr. Bale. Here is an <a href="http://www.avweb.com/podcast/podcast/AudioPodcast_USAirwaysFlight1549_Audio_199716-1.html?kw=AVwebAlert">audio recording of the (brief) flight</a>. Don't worry if you don't understand the combination of New York accent and aviation-speak going on for most of the recording. The important parts are clear enough.<br /><br />Ok, so let's compare Bale with Sullenberger.<br /><br />One is irritated because some one moved around on set. Now granted, I'm sure this threw off his acting, but you know, it happens all the time that I'm at work and someone comes over and talks to me, throwing off my mojo just when I'm really in the zone. <br /><br />Now listen to the airplane. They are going to crash. It is not a "we might crash" situation, but a "how bad will we crash?" situation. Will we all freeze/drown in the river? Will we be burned to death in a fireball? Smushed in the impact? Or some sort of more graceful crash?<br /><br />Do we hear "What the F&*^ are you doing, geese? What are you doing flying in my way? I mean F*&(^, you call yourselves professional?" No. We hear "unable..." repeated over and over.<br /><br />Someone should take cool lessons, I think. On the other hand, there might be a sort of "Dark Knight" curse. Like Poltergeist had. Or not. Bale could just be a jackass.<br /><br />Oh, and going back to the airplane, I have a few amusing notes:<br /><br />I like the guy (he's the tower controller at LGA) who asks for confirmation of which engines failed. What part of "both" don't you understand?<br /><br />I also wonder if, at some point when the main controller asks "what do you need to land" or some variation, the thought occurred to one of the men in the cockpit "two new engines!"<br /><br />And even though the controllers get a little confused (briefly talking about flight 15<em>2</em>9), it is remarkable that, for all they know, this airplane just ended up a smoking hole in the ground, but they keep shuffling the rest of the airtraffic around. <br /><br />One final Flight 1549 note -- this incident has been <em>big</em> news in the aviation community. It is rather interesting to think about why. Why do I think everyone is so interested? Because <em>no one died</em>. Since everyone made it off, and the overall tone was one of heroism and miracle, there is no finger pointing going on. <br /><br />A normal crash investigation is very much of a blame attribution situation. And if there was any serious loss of life or property, then that blame could end up having huge financial and legal consequences. If the NTSB or other investigative agencies report that an engine or aircraft component was substandard, or that maintenance was ill performed, then that report will have obvious influence on the inevitable post-crash legal actions.<br /><br />But this time, everyone was OK. Some luggage was lost, or at least ended up quite wet, but I don't hear anyone whining about that. <br /><br />And since the results of the investigation are free of any legal consequence (and therefore there is much, much less of a place for political and industrial pressures to enter into the investigation), those working to understand what happened can focus on understanding what happened. What worked, what didn't, what should be done the same next time and what should be changed.<br /><br />Besides, it is a hell of a lot less morbid!Just Nickhttp://www.blogger.com/profile/01845987547854457407noreply@blogger.com0tag:blogger.com,1999:blog-5333608194352082143.post-80217419812071672222009-01-16T06:41:00.001-08:002009-01-16T08:42:50.946-08:00How do you dead-stick an Airbus?Well, for starters, you have Cap' "Sully" Sullenberger at the controls. From what I can tell, yesterday's amazing A320 ditching in the Hudson was a case of having the right guy (Sully) in the right place (left hand seat of flight 1549) at the right time (shortly after the impact of a large number of Canadian Geese).<br /><br />Oh, and regarding those geese, I knew I never liked those things...<br /><br />Anyhow, as the relevant authorities do their investigative work and aviation-centric press writes its stories (with more insightful information that the one observer, quoted on CNN, who seemed to take pains to point out that it "was not a seaplane.") I thought I'd put a little guidance out there for anyone who wants to try to ditch an 'Bus of their own. You know, on Microsoft Flight Simulator, X-Plane, or the like. If you hold a current ATP certificate and are carrying people in the back, please do not attempt these procedures unless you have recently made the acquaintance of a large number of geese.<br /><br />Actually, in all seriousness, these are the dual engine failure and ditching drills from a real A320 flight manual -- the drills that would have come in to play yesterday at about 3,000 feet over NY. If you look at Flight International's <a href="http://www.flightglobal.com/articles/2009/01/15/321166/us-airways-a320-crash-lands-in-the-hudson-river.html">reconstruction of the aircraft's flight path</a>, it looks like the following unfolded over the span of about four minutes time, beginning at an altitude of about 3,200 feet.<br /><br />TO help set the scene, he's a snap of the relevant sectional chart, courtesy of the fantastic <a href="http://www.airnav.com/airport/KLGA">http://www.airnav.com/airport/KLGA</a> and <a href="http://skyvector.com/">skyvector.com</a>.<br /><br /><div style="TEXT-ALIGN: center"><img height="167" alt="Picture 6.jpg" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEji_VHPmJmRLUhYjJPIRMLpI4RpJp77epHrsvlef5AMGgh88Kv8f_QEtrq8BmfvDUquNujL4Wu8jsAssCuHYPl98bCVYuaF7gcOHnWsJO9Q0vjmkuJR-EPzu_Sj1FV_O-seeKoMcua13RLO/?imgmax=800" width="283" border="0" /></div><br /><br />Flight 1549 took off from LGA heading to the Northwest. It is easy to see why Captain Sullenberger chose to head to TEB -- it was more-or-less a straight shot with no need to turn. But given the alignment of the Teterboro runways, he'd have had to aim for a point quite a bit to the South or Northeast before turning to align with the runway (just making it to the relevant dot on the map doesn't count when you've got an aircraft to land). All that maneuvering takes energy, which is exactly what he <em>didn't</em> have.<br /><br />Anyhow, the Hudson proved conveniently close and full of helpful (in, I'm sure, a gruffly New Yorkish sort of way) ferry boat captains.<br /><br />And, as promised, the relevant procedures and hopefully a little (if coldly technical) snapshot of what was going on in the cockpit. Airbus' manuals are dry, technical, and descriptive. More Germanic than Gallic, I find, lacking the sort of wry humor that occasionally pervades the worst-case sections of flight manuals (the Space Shuttle manual is, oddly, a great example of such humor). I do, however, like the blunt statement of the obvious at the top of the dual engine failure list: LAND ASAP.<br /><br /><div style="TEXT-ALIGN: center"><img height="382" alt="Picture 1.jpg" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiI6-V4qmlpsTrqBc0hYwdHxkKt0HBn4VMI_6p1s-X_VzaVjNJLm7gyQjTSjjJ5oN4JGwyKo9aPoG2Sb0W_vDWQ5RPYMdebdlPtuMFCHtEJhzf76ExEjImoK-Oz31TfS7OWN98IoEMhOpcw/?imgmax=800" width="369" border="0" /></div><br /><br /><div style="TEXT-ALIGN: center"><img height="422" alt="Picture 2.jpg" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgLbOqeikHIKTQUJsGZzmO0eiEPSUpK8-HpbkcKNVDkwAnyorRdIL37ZnzED16yBMJoCa_D_iq1hxEvsOGGLR5NorMQy4Syr0zd1SI3lgh3wCOawKcJjZVmneexAAO8SrPM0GALY5XitybW/?imgmax=800" width="367" border="0" /></div><br /><br /><div style="TEXT-ALIGN: center"><img height="423" alt="Picture 3.jpg" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgcAsRtwOgZb7LGg1M5_ta-MvuHyPA4_D1obUUsY7f46lt3uqcu_1ofiPM1ud55fMMc8t-7DBSOg6RtBkp1nBBxrdLW3ycCEYAy8CIGhnhI8DDx3L42rwDvNwBNH1LYW9OtyME4Xz4tdwmg/?imgmax=800" width="366" border="0" /></div><br /><br /><div style="TEXT-ALIGN: center"><img height="406" alt="Picture 4.jpg" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh8nvbwAJ6Hs5JT_2gIYe7VMo1xk7LB0w9c0Bl1ZTDdTSLWvpIWOe5Es1mXa1Kxan8f1EAG0rDjtg-Rfiyju1O1DCCdAuES4LmBr-kFzITSSOVRejmdB9kM3A3exd9cNG82bdSpRi8e6Hb4/?imgmax=800" width="367" border="0" /></div><br /><br /><div style="TEXT-ALIGN: center"><img height="178" alt="Picture 5.jpg" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhntMIDzY69C1E8f9kaxIzREimD_HT5G5iKiePDCXLHQemT1A7v-ZCj69hJLGzIUcr3XrDyrqSuOuuBB6hDj9s8Bi__9LhR3_TctVgTSYRCZ8nQcfLZbjj5dESVYPDg8ZEuVaDV4jBUxhds/?imgmax=800" width="368" border="0" /></div><br /><br />Questions and comments, if you got 'em, to the blog or to strauss(dot)nick(at)gmail(dot)com.

First off, the multi-part thing just didn't fit the open letter format. I mean, did I really think Obama would read my blog? And more than one entry, particularly at the current pace of production? No way.<br /><br />Secondly, I wanted to make it clear from the outset that this wasn't a political entry. Not really, at least. It wasn't going to have anything to do with cabinet posts, inauguration day speakers, or any of the other stuff about which people seem inclined to express their opinions at the president elect.<br /><br />Oh, and I find the phrase "president elect" horribly ungainly. Which, given my sentence structures, is probably saying something.<br /><br />What this blog <em>is</em> about is space science. And, therefore, at least a little bit about politics. Because, while I will generally steer clear of the whole Griffin-at-NASA thing, a certain degree of politicality is inevitable. But more on that later. <br /><br />This blog is a suggestion, a plea even, for a well thought out, science based space program. I have some very specific thoughts on what this means -- right down to what missions should get funded. And, frankly, I'd like to be put in charge of this project. Just give me $24 billion. I'll lay the plan out.<br /><br />As I worked on this entry, I realized that if I wanted it to avoid turning in to a space geek's fantasy laundry list of rocket launches and space missions, I'd need to make the underlying rational clear. And that forced me into a length that well exceeded the patience of even my most devoted readers (who are family members, so you should get the idea I could go on about this for a very, very long time, particularly if whiskey is involved). So today we begin with Part One: what exactly do I mean when I talk about a <em>science based</em> space program.<br /><br />Well, and I say this partially because I love building suspense, it'll take some time to get there.<br /><br />I posit that there are <strong>five</strong> reasons for space exploration. These reasons could apply globally, to an entire national space program or effort, or to a single launch or mission. They can mix and combine and share the drive behind a particular project. An given project can see its genesis in one reason but bear fruit along another axes. Things are complicated. But five reasons is a nice place to start with.<br /><br /><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhooVcAUQuMG59jZeJNA-FIf846pHwGqhtnHITtU_ZB9mp8sABNWIXbjvAokXqa61rhycpCCUeeWSoDPki_Jq4YbRmrmVsn8VrJ9PE3NqPgi70s6zNjAyYBr_xFdC6010l3oSqVYJoJUQVg/?imgmax=800" alt="images.jpg" border="0" width="126" height="150" align="left" /><strong>Number One: Achievement</strong><br />John Kennedy invoked the sense of challenge when he commissioned the high point of American space flight, the Apollo moon landings. The reason was simple: the moon was there, landing a man there was (barely) achievable, and it was a great way to try and compete with the then surging Soviet space effort. The result was a galvanizing technical (and emotional) effort, a great deal of national pride, and a moderate amount of science. Apollo was great. But it was done (to paraphrase Sir Edmond Hillary) "because it was there."<br /><br /><strong>Number Two: Function</strong><br />Spy satellites, communications satellites, weather satellites all do useful things. They may not be glamorous, and they rarely break tremendous new ground, but they get the job done. Workmanlike, they bring home the results, civilian, military, public sector or private sector.<br /><br /><strong>Number Three: Enabling</strong><br />Sometimes you do something so that you can actually do something else. Sometimes you spend a great deal of effort building a jig. The jig itself is uninteresting, but the chair that it yields is beautiful. The American Gemini program did this in space -- it taught us how to fly, spacewalk, maneuver, and troubleshoot in the vacuum of space. The Space Shuttle was marketed as a utility truck much along these lines once, and the current International Space Station is often sold as a tool to help us learn how to survive and construct in space.<br /><br /><strong>Number Four: Exploration</strong><br />Gene Roddenberry, this is your moment. The bold going. Or going boldly. The Pioneers and Voyagers, heading off into regions unknown, to see what has never been seen before. Details are not important -- for every byte of returned information contains precious sights of the here to fore unknown.<br /><br /><strong>Number Five: Science</strong><br />The explorers set forth with no questions, only open eyes. The scientists set forth with questions, ideas, and theories. They seek explanation and understanding, they want verification or refutation, they require detail and precision. They may find the unknown or unexpected, but they set off not with an empty mind, but a mind full of questions.<br /><br />Alright, so those are my five. It once started as three, but Enabling and Function appeared as late additions. None of these descriptions are intended to be praising or critical, merely descriptive. For all things can be good in the right time and place. And what, then, is good at <em>this</em> time and place?<br /><br />Well, let's take a look at Achievement. That one, basically, is politics. It is about doing something (or doing something before someone else does it) for reasons related to motivation, goal setting, national pride, international relations. I am not a politician and do not pretend to a degree of competence or awareness of the full complexities of the international arena beyond that of the average moderately well read adult. And so I check out of this one. Politicians, make your choices. But this is not an area where I will make the call.<br /><br />And with that goes manned space flight. Sorry, everybody. People aren't part of my program. They are too expensive for what you get back. Great thrills, beautiful video, and a truly motivating and empowering feeling when done right. But the price and the risks are too great to justify human space flight for any reason other than that of Achievement (or politics).<br /><br />Function is pretty good -- but not with people. I'm tired of the circular logic of a manned space program that justifies its own existence with the endless loop of providing more understanding of how to allow humans to fly in space. Why? What is the point? What is the point of learning how to get people to survive in space for two or five years unless you are <em>really</em> going to Mars. And let's get real. Not happening, that one. <br /><br />But functional <em>unmanned</em> space flight is doing great. It is very well established by government, military, and commercial agencies.<br /><br />Exploration is another noble reason that struggles in today's reality. Exploration is about the low hanging fruit in some senses -- you have so little information about something that you are excited to get even a basic glimpse. The implication is that the technological act of <em>getting there</em> is where the challenge lies. Problem is, we've got all the good getting in this regard. Except Pluto and, thank you Allan Stern, New Horizons is on the way and doing great. <br /><br />Which leaves us <em>science</em>. The serious quest to understand our universe (and a few other things). Not helter-skelter pursuit of goals that look or sound good. But the systematic quest for the deep, subtle, and profound knowledge of how things work. The universe, life, and our planet.<br /><br />And so from that final remaining reason, we must move on. But first, to review:<br /><br />Achievement: too political, too expensive (if manned)<br />Function: already well handled by others<br />Enabling: only worthwhile if stepping stone to legitimate goals<br />Exploration: most reachable stuff has been done<br />Science: bingo!<br /><br /><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjRZYUiX3iEJ4WTcZLZNPhb21gzDjpn8ZQgDWoqHqxpYfc3tFN1upX6yvS1F-vO21PWB2i8oFKBCduiflhasLx7uywmTS5s-8mkH05skvcJ81VleDRXANvU9cJ0w7tbrqPvsjj5tLOoIh3w/?imgmax=800" alt="images-1.jpg" border="0" width="150" height="150" align="left" />So what is this science based program supposed to be about, then? How do we make sure we stay on that particular target and don't go wandering into another one. Well, for starters, some wandering is going to happen. Apollo, while a clearly achievement based project proved to be very enabling and did a great deal of exploring. So we accept that.<br /><br />Secondly, devise a clear definition of what sort of goals we want to achieve. Write these goals down in large letters. And make sure that anything you pick fits within this charter.<br /><br />Now, for my sake, I admit that this was a case of backing into a definition. Because honestly, I found this was one of those things that, like the old joke about pornography, I may not be able to define, but I know it when I see it. But I wrangled and experimented and finally defined myself a set of three goals that express the ideals of the rational, science based space program. In forming this definition I wanted to avoid the trap of forming a laundry list, a long rambling list of commas and (God forbid) semicolons. I wanted a single, elegant, coherent statement. If you can't break it down (<em>whatever</em> it happens to be) into a single sentence, then you have a problem.<br /><br /><span class="Apple-style-span" style="font-family:'courier new';">To understand our <strong>universe</strong>, our <strong>planet</strong>, and the place of <strong>life</strong> in the cosmos.</span><br /><br />And there you have it. One sentence and with fairly few commas. It works better with three, though:<br /><br />Understand our <strong>universe</strong>, its origin, evolution, and nature.<br />Understand our <strong>planet</strong>, the forces acting on it, and the changes it is undergoing.<br />Understand the origins of <strong>life</strong>, life-bearing systems, and the potential for life to exist elsewhere in the cosmos.<br /><br />I also gave myself a tidy (if arbitrary) limit of <em>ten</em> missions that I could fly. They should all be achievable by the end of the next decade (2020). And they should fit within a budget of $20 billion ($2 billion each, on average) including launch, support services, margins, and a well crafted outreach and education program.<br /><br />The resulting ten missions span a range of deep space explorers and earth orbiting environmental probes. They include telescopes, radars, balloons, and sample return capsules. They are based on missions that NASA or ESA has studied or is studying for implementation within my timeframe.

Now I don't want to go saying that aforsaid economic crisis is some sort of small time setback, but I'd like to make the point that when the going gets tough, the tough had better have decent business plans. And when you have a fundamentally flawed model -- and are selling a fundamentally flawed product -- and have fundamentally flawed management and customer relations practices -- you are basically screwed no matter what happens.<br /> <br /><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgRdAz2vIl99b46PyPOPzXedcwiy_feIj0rn8cZ0jgZl7ywf791qJHdPQyZTT14zaUuh3m0hAjZPJVvzfD0ehGtvQw7Rjcit0MhMbV7w1GVu785b24qATm6Q6LpwmhmsoLiyu6-Kqez5vMU/?imgmax=800" alt="Eclipse1.jpg" border="0" width="270" height="180" align="left" />Eclipse was a company that might have survived a few more years had the original timing worked out. They'd have launched towards the beginning of the boom and managed to get a few hundred products delivered before the carpet was so cruelly yanked out from under them. Odds are a lot of those little jets would have been repo'd, but that's another story. But I think that a longer life (and more sales) would only have lead to their death by other means -- the fundamental design, production, QA, QC, and customer services issues would have had enough time to come (further) to light and killed Eclipse off just as surely, all be it more slowly, than the economy tanking appears to have.<br /> <br />It is a bit like the arguments that circulate around assisted suicide or on nighttime crime dramas: if you take a life of someone who is going to die soon enough anyway, how much of a murder is it, really?<br /> <br />The missed payroll two weeks ago was the final warning bell, the tocsin announcing that the end was mere days away. I am sad for those employees of Eclipse who were toughing it out until the end, hoping that the dream had been built upon firmer footings. But I've been part of a business plagued by systemic strategic, ethical, operational, and managerial issues just like Eclipse. And you could sort those of us at that operation into two camps: those of us who knew the place was a s&*% hole and were looking for a way out and those of us who knew the place was a s&*% hole and were too scared to take action. Either way, each person's destiny was came down to their own active or passive decisions and pointing at the company's flaws will only get you so much pity, not when the writing is on the wall for anyone to see.<br /> <br />So my best wishes to those of you at Eclipse who were trying to keep the dream alive -- and when things rebound and lessons are learned, I hope to see a new product of your efforts in the air. And before anyone goes pointing this out to me -- I know that Chap'11 isn't the true death of a company. Many concerns have emerged, successful and vibrant, from protection. But it is such a dramatic indicator of failure at so many levels that in this case, I do think, it spells the end of Eclipse as we have known it.<br /> <br />But in the meantime, as ever, <a href="http://noodlebook.blogspot.com/2008/08/aerospace-is-harsh-mistress.html">aerospace remains a harsh mistress</a>.<br /><br />Just Nickhttp://www.blogger.com/profile/01845987547854457407noreply@blogger.com0tag:blogger.com,1999:blog-5333608194352082143.post-89168187444365958282008-11-24T12:29:00.001-08:002008-11-24T12:29:46.589-08:00The fun of bringing light to the dark -- metaphoricallySo I decided it was time to give politics a rest. This isn't, after all, a political blog. It is a blog about odd, rambling things like wind tunnels and cocktails and cipher systems. And so, after the quiescent period following the election, as I slowly bring The Noodlebook back to life, I thought I'd get it going with a little science.<br /><br /><a href="http://en.wikipedia.org/wiki/Dark_energy">Dark energy</a>, to be precise.<br /><br />And not even dark energy as such because, let's face it, both my own small skill as an elucidator and the period of time I have available for this endeavor are dramatically inadequate for tackling so deep a mystery. Instead, in the classic talk-about-the-talking postmodernism of blogs, my attention turns to the investigations seeking to understand this phenomena rather than the phenomena itself.<br /><br />I have, after all, always been much more of an experimentalist than a theoretician.<br /><br />But to recap, dark energy is a postulated force that would explain some rather odd behavior of the universe. The oddity in question (for there are several oddities about our universe that require postulated things to explain them) is that the universe seems to be expanding at an ever increasing rate. Now that the universe is expanding is not at all odd. We've known about this since Edwin Hubble, a man brilliantly characterized as a "large mass of ego" by Bill Bryson, noticed that all the galaxies in the universe are expanding away from each other. Subsequently, a series of theories beginning with the "big bang" and moving on to modern inflationary cosmology have homed in on the idea of the universe originating at some sort of very small beginning (there are a few variations) and expanding outward from some sort of initial impulse (again, there are a few variations).<br /><br />This is all fine and good and if you want some ideas about the how/why on that it won't surprise anyone that I now recommend Brian Greene's <em><a href="http://www.pbs.org/wgbh/nova/elegant/program.html">The Fabric of the Cosmos</a></em>. But this expansion should be slowing -- as the shared gravitational attraction of all the, well, stuff in the universe gathers together and pulls on itself. And for a few billion years, it appears that it did. But then a few billion years ago, the rate of expansion began accelerating again. There is no good reason for this, not with the rule that we've been playing by.<br /><br /><div style="text-align:center;"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgk92pnuegkYYs9i3a40_HbLrYdt08SbKyo0-M8_xfNfirIuAywxdjcl3hIhOsnJ2w50YOve3Xhv020OVvdQQfLDym2SefJaqQd6SN44xdgWOF9Fx0vZqhA55SOQEJ_WK6Bz8lQSEUJBmIQ/?imgmax=800" alt="dark_energy_diagram.jpg" border="0" width="381" height="400" /></div><br /><br />It is as if, to invoke a classic Feynmanism, we were watching a chess game, thought we'd got the rules and moves pretty much figured out, and then someone castled. Uh-oh, what the hell was that?<br /><br />Since then, cosmologists, astrophysicists, particle physicists, and plain old ordinary physicists have all gotten in on the bandwagon to try and explain why. The lure of being the first to explain a new (or dramatically revised) physical force is a pretty big one!<br /><br />Alright, enough of that back-explanation. I said that actually trying to <a href="http://www.scholarpedia.org/article/Dark_energy">explain dark energy</a> was beyond me. Oh, but it is different from <a href="http://en.wikipedia.org/wiki/Dark_Matter">dark matter</a>. I know. They could have come up with some more varied names. Like "The Smuckers Effect" or perhaps "The Universal Choo-Choo." Either one might have been better.<br /><br />So this dark energy stuff, whatever it is, is suddenly pushing the universe apart faster and faster. Or not so suddenly. Or it remains constant or decreases as a quadratic function while gravity decreases as a cubic function. Sorry. Got distracted again. The point is, we have no idea what this force, this dark energy, is. We can only observe what it <em>does</em>. And that makes it a wonderful place to study and understand the interplay between observation (experiment, if you like) and theory.<br /><br />Science proceeds, in an idealized and perfect world, as a series of iterative steps. Someone observes a phenomena (say the increased rate of expansion of the universe). That person (and a few others) say "Damn, we didn't expect that!" Everyone then retires to their chalkboards and starts thinking of <em>theories</em> to explain what is causing this phenomena. The theories will span a broad range. Some might involve zero point energy, others extra dimensions, still others giant turtles. As the theorists theorize, the experimenters begin to contemplate the next round of experiment or observation (I think of experiment as an active act -- where we <em>do</em> something, such as at a particle collider -- while observation is a passive act where we take data on what the universe is already up to -- as with a telescope).<br /><br />Theorists and experiments/observers are different. The former are the ones with the unkempt hair, the latter the ones with the dirty clothes and coffee addictions (particularly in astronomy).<br /><br />Anyhow, while the theorists are using their imaginations and running the numbers, the experimenters/observers are doing their thing and building the next generation of machines. What proceeds then is something like a lottery. Or perhaps a reality TV show, though I doubt "Survivor: CERN" or "America's Next Top Scientists" or "Theorizing with the Stars" will take off anytime soon.<br /><br />Any good theory brings a few ingredients to the table. It must offer an explanation for <em>why</em> the phenomenon under consideration occurs. It ideally should offer a mechanism to explain <em>how</em> it occurs. And it should provide some sort of mathematical formula that can fit the observed data to a high degree of accuracy. Lastly, that mathematical rigor should allow for some degree of prediction of as yet unobserved phenomena that can test the accuracy of the theory. This prediction might simply involve taking the measured predictions to a few orders of magnitude more precision. Or it might involve a wholly new physical manifestation. Either way, it provides some way of telling if the theory will have the winning number come lottery time -- the return of experimental results.<br /><br />We go round and round like this. The results from each round of experiment feed the next round of theory. The predictions of a given round of theory guide the direction in which the experimenters/observers turn their searching. Rarely, however, are things so precisely beautiful as this, like turns in a board game. Usually, after a while, everything gets all out of synch and the experimental and theoretical processes get all overlapped.<br /><br />But dark energy is new. It was accidental in a wonderful way, and the demands of further experiment have allowed for a long and fruitful phase of theoretical contemplation. And now the experimenalists are about to have their day. And by now I mean in about eight years, because that is how long it takes to get a space mission from budgetary contemplation to launch pad. And then a few more years of taking data.<br /><br />Science is for the patient, these days.<br /><br />This whole process of theory-experiment (or observation) is crucial to the scientific quest for understanding. It always galls me when people talk about how scientists don't actually know anything -- they just have a bunch of guesses. This points to a fundamental misunderstanding of what a <em>theory</em> is. It isn't a guess. If it was, there might be some credence to the idea of giant turtles playing a role in dark energy. Rather, a theory is an educated attempt to explain a phenomena. It is a look by a very experienced observer at a set of behaviors, an assessment of what those behaviors might mean, and an attempt to predict what they might mean for the future.<br /><br />We all form theories all the time. When we spot a car swerving erratically while driving at 2am, we say "Woah, look how that dude is driving. I betcha' he's drunk. Look out, he might miss that turn..." We observed phenomena, offered an explanation, and attempted a prediction. The depth of prediction can be tricky. If we only say "This driver will keep swerving around" it may not eliminate other possibilities such as looking for something he dropped, having an epileptic seizure, or making out with the passenger. But it is entirely possible that a drunk <em>will</em> in fact make that next turn too. Or never intend to take it.<br /><br />The scientific process is nothing different. It is not (and does not pretend to be) a fixed rulebook. It is an evolving set of understanding of the universe. Science is not a set series of answers as it is so often (and so wrongly) presented. Rather it is a <em>process</em>, a pursuit of those answers.<br /><br />And so when more accurate measurements gave rise to results that disagreed with the predictions inspired by Hubble's results, the result was not joy and frustration, but excitement at the opportunity to solve a new puzzle. An Asimov quote that those who have read email coming from my work address will recognize summarizes this mood better than anything:<br /><br /><blockquote>The most exciting phrase in science, the one that heralds new discoveries, is not "Eureka!" but "That's funny..."</blockquote><br /><br />And now the prospect of dark energy is out there, proposing a grand enough prize and an exciting enough pursuit that seemingly everyone is getting into the game. Established scientists, cranks, those hawking ideas from the fringe, conspiracy theorists, random posters on the Internet: each one has some idea, spun slightly to reflect individual specialities and biases, for what might be at work.<br /><br />The observational guys have been at it just as enthusiastically, constantly devising new approaches to reflect the latest ideas of the theorists and the latest technological developments in measurement apparatus. Dark energy isn't something we can test in a laboratory with a dark-energy-ometer or create with a steel cased apparatus connected to several thick cables. It acts, by all accounts, over vast distances and only manifests to a measurable degree when other forces (namely gravity) are at their most feeble. And so an earth-bound measurement (even if we knew what to look for) seems doomed to be swamped by noise.<br /><br />This results in observatories. For various reasons, these would be observatories best sited in space, at the L2 point about a billion miles from earth, where it is dark and cold and not much gets in the way. The idea would be to observe, with great precision, the distances and recessional velocities of several thousand (or million) objects in the middle distance of the universe, the distances over which dark energy starts to manifest -- out to about twenty billion light years (117,580,000,000,000,000,000,000 miles).<br /><br />A few approaches have shown up. The first involved hunting for something called Type 1A supernovae. These moderately rare explosions function through a well understood mechanism that has the handy feature of producing a reliably predictable brightness. The result is something called a "standard candle" -- an object of known intrinsic brightness which allows the estimation of its distance by comparing that source brightness with the observed brightness. That's good -- and Type 1A's are how this whole dark energy thing got started -- but it turns out it is not good enough.<br /><br />Clouds of gas and dust can get in the way and it always is possible that we don't understand the Type 1A quite as well as we thought we did. So more recent approaches to understanding dark energy have tried to invoke several different techniques of measurement. Acoustic Baryonic Oscillations (I'm still trying to figure out what those are, but they sound really interesting), weak lensing, and a few others have all surfaced. The result is that any dark energy space mission that actually gets flown will end up as a fantastic multi-disciplinary observatory, quite different from the specialist that was originally envisioned. <br /><br /><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh_eKrCDHJBInps5nWofb5zRvnuXt5WzrCOcPBe8wCbYypRo-zmdrp076SKcocz3u7ltH0VhKNwFzwRaZhVN2CNjQ0F8NcL2wF7yqSS6rV-w6IF8EPOiWB6NiQMRYIVx1hgUeajuEN4Xn7G/?imgmax=800" alt="Picture 14.jpg" border="0" width="222" height="348" align="left" />The glory of all of these approaches, and of all of the missions that seek to imlement them, is that they will conduct their work through massive "wide and deep" surveys. Taking vast numbers of long exposure images across a large area of the sky, in other words. This is the advantage of a dedicated mission -- Hubble or the James Webb could do the same science, but are general purpose instruments contended over by the entirity of the vast astronomic (and astrophysic) community. But a dedicated mission, running a pre-planned scheme of observation, can produce the staggering amount of data that is necessary for the statistical analysis upon which dark energy studies must be based.<br /> <br />But this vast survey, while intended to specifically test a signle scientific concept, will also have enormous implications for the rest of the community. Currently, we stare through straws, looking across the vast night sky to find things that are interesting. Sometims we do so by chance, but more often we do so by looking at areas that we've already identified as interesting. The terabytes of data coming back from SNAP, DESTINY, ADEPT, JDEM, SPACE, Euclid, or whatever mission or missions end up flying will end up producing an astronomic and astrophysic legacy ready for the picking. A generation or more of astronomers and astrophysicists will mine this legacy to confirm and clarify their theories and hypotheses. And, here and there, they might discover something completely new, something entirely unexpected, something funny, and start the whole glorious process over again.Just Nickhttp://www.blogger.com/profile/01845987547854457407noreply@blogger.com0tag:blogger.com,1999:blog-5333608194352082143.post-73194439781336340732008-09-12T16:35:00.001-07:002008-09-12T16:35:25.801-07:00Beamlines and Black HolesCollisions happen -- world fails to end.<br /><br /><img src="http://lh6.ggpht.com/strauss.nick/SMr8kubN5OI/AAAAAAAAAP8/tEBWnFtY2kA/180px-SLAC_entrance_sign.jpg?imgmax=800" alt="180px-SLAC_entrance_sign.jpg" border="0" width="180" height="115" align="left" />That's pretty much all the fame and fortune that the most powerful (and expensive) single high energy physics experiment in history has received. I'm not going to go into the whole history or controversy surrounding the amazing new atom smasher (I <em>love</em> that phrase!) down by Geneva, LHC. But rather to relate the events at the Large Hadron Collider to some of my own experiences working at the Stanford Linear Accelerator Center -- SLAC. Everyone's favorite string theorist, Brian Greene, wrote a <a href="http://www.nytimes.com/2008/09/12/opinion/12greene.html?em">wonderful piece</a> for the New York Times that better explains the search for the Higgs and the whole tiny-black-hole scare way better than I could.<br /><br />My time at SLAC, to move on, is one of those crazy things on my resume that has, unfortunately, rolled off below the fold and so I don't get to talk about it at job interviews anymore. Along with my time at Amazon, my time at SLAC has the feel of being part of something more than my immediate job. At one, we changed the way people looked at business and commerce. At another, we added to the depth of our understanding of the universe.<br /><br /><img src="http://lh6.ggpht.com/strauss.nick/SMr8oPaTDyI/AAAAAAAAAQA/zG7hX-c1L0M/180px-SLAC_long_view.jpg?imgmax=800" alt="180px-SLAC_long_view.jpg" border="0" width="180" height="120" align="left" />Whereas at Amazon we may all have been acolytes following the word of The Bezos, at SLAC we were all acolytes performing arcane rituals of devotion and sacrifice to a multi-mile long vacuum filled tube and a collection of magnets, giant RF amplifiers called klystrons, and the associated cast of power supplies, measuring systems, controls, pumps, and all the rest. Electrons were hurled down the pipe, hammered along my enormous amounts of radio energy, looped through a heart-shaped half-circle and slammed into a corresponding beam of their antimatter counterparts, positrons. When these teensy particles are accelerated, thanks to some clever connections in the fundamental ground rules of the universe, they actually increase in mass/energy. So the resulting collision released an enormous amount of energy -- and in all kinds of interesting particles. A massive cryogenically cooled detector could track these heavyweight fragments and provide data on their behavior.<br /><br />These behaviors served to confirm, refute, or inspire the work of theorists. Science works (in theory) like this: a phenomena is observed. Scientists devise a theory that explains the cause and behavior of the phenomena. Scientists use this theory to predict some as-yet-unseen phenomena. Experimenters then go looking for this new phenomena to verify the veracity of the theory -- or to force a re-examination.<br /><br />At SLAC, we were poking at some odd asymmetries in particle production. Simple theory says that at the point of the creation of the universe -- the big bang -- equal numbers of "conventional" and "anti-matter" particles should have been produced. Anti-matter is nothing like as weird as they make it sound in <em>Star Trek</em>. Any given particle just has the opposite charge of its normal partner (incidentally, this means there are no anti-neutrons). And if examples of the two ever meet, they annihilate each other in a total conversion of mass into energy, but that's no big deal. When we talk about "massive" amounts of energy we are talking about massive for the scale of the objects colliding. SLAC collisions produced less energy than the impact of a settling grain of dust. LHC collisions are on par with two mosquitos ramming each other head on. <br /><br />Remember Churchill's classic quote that Russia was an enigma wrapped inside a mystery wrapped inside a pierogi or something like that? SLAC was much the same way -- though the wrappings were not nearly so clear cut or tasty.<br /><br />The old 1960's vintage technology has been updated countless times in 40 years of physics life. And when I say "updated" I don't necessarily mean "replaced." When I was working there, at a facility merely thirty years old, traces of the original control system remained. Buried in a dusty room somewhere was the original control console for the two mile linac. The console was dusty too -- but an amazing artifact of that era of engineering that I find so fascinating. Entirely electromechanical it had some absolutely crazy things going on -- one that I remember was a series of potentiometers (knobs) about 2/3 of an inch around that had the readout gauge for some corresponding parameter built into the face of the knob. My undergraduate brain marveled (and still does marvel) at the complexity of creating such a system. No touch-screen-and-slider back then...<br /><br />But back to this console, it a dusty room. It was a big room, stacked with semi-discarded gear, and the console had been shoved over to one side of it, pretty much out of the way. But it was clearly still active -- several fat bundles of cable came out of the back and snaked across the short distance from floor to wall. Turns out that when the SLAC control system had been updated as part of the SLD project (or perhaps sooner) the hadn't actually <em>replaced</em> the old control system. They'd just spliced the new computerized system onto it. This control panel was still active! Inputs came in to it from the computerized system and then back out again to actually run the system.<br /><br />I pictured the machine running something like this: engineer makes parameter changes on a DEC Station or whatever kind of UNIX boxes we were using for the front end. That uses our 10BASE2 Ethernet to talk to the big VAX 11/780 that was sitting in a glass-paneled room in the Main Control Center looking <em>very</em> much like the WOPR from <em>Wargames</em>. That communicates by some arcane variable voltage or pulse counting analogue signal to the mysterious control console which passively relays the engineer's request out to the actual magnet or power supply or pulse generator.<br /><br />From what I remember, that old console's gone now, junked alongside the SAGE consoles and all the other detritus of 1960's engineering. And SLAC is undoubtedly better for it: more reliable, simpler, and easier to keep running. <br /><br />But the point is that that old machine was a <em>living thing</em>. And I'm not talking about the mutant cockroaches that would sometimes call up from the higher rad parts of the beamline. The machine was moody, irritable, frustrating, and occasionally satisfying. When people in the Sacramento Valley turned on their air conditioners in the summer and our power supply wiggled about, parameters on the machine would start to waiver and falter. When large trucks drove by (or for that matter tiny earthquakes -- we were a more sensitive seismograph than anything the USGS possessed) the beam would waver. Actually the beam didn't waver -- it kept going still -- the machine wavered around it.<br /><br />My point is that we needn't expect the universe to end anytime soon. I'm sure that CERN has, with the LHC, put together an extremely well engineered and carefully planned machine. One that will, I hope, suffer from few of the artifacts of kluging that beset SLAC. That said, the LHC does rely on the existing SPS for initial acceleration, but in a much less critically integrated way. Instead I'm sure they will face the challenges typical of an entirely new system -- challenges of converting the theory and plan of operation in to practice. <br /><br /><img src="http://lh5.ggpht.com/strauss.nick/SMr8uSrRmWI/AAAAAAAAAQE/iRXF_VZQVrE/300px-First_Gold_Beam-Beam_Collision_Events_at_RHIC_at_100_100_GeV_c_per_beam_recorded_by_STAR.jpg?imgmax=800" alt="300px-First_Gold_Beam-Beam_Collision_Events_at_RHIC_at_100_100_GeV_c_per_beam_recorded_by_STAR.jpg" border="0" width="300" height="231" align="left" />At SLAC that moment finally happened late one night when an operator off the late shift decided to experiment with some beam parameters in an unconventional way. For months the LEP collider (footnote -- the LHC is built in the tunnel originally constructed for LEP) had been providing a good deal more luminosity than us -- working in the same energy range but producing a LOT more collisions. Particle physics is, to a very great extent, a statistical science and it takes a good sample of behaviors to understand how you need to plot the graph. Our individual collisions produced cleaner data, but they were winning in a quantity-over-quality fight.<br /><br />We'd been struggling to get the machine to do what it was <em>supposed</em> to be doing. On paper, our luminosity figures were good enough to return some really nice science -- but reality wasn't corresponding with paper. I don't remember the exact story anymore, but for some reason, one night, this operator had an excuse to get a little creative with the settings on our two-mile-plus electron gun. She tweaked things in a way that I recall being, in retrospect, very intuitive but entirely opposite of the "party line" for how the thing was supposed to be set up. Suddenly we got a spike in collisions and the luminosity figures were trending towards what they were supposed to (and needed to) be.<br /><br />From nightshift operator to hero, in just a few key parameters.<br /><br />I'm sure that LHC will have its similar moments where you realize that either the individual protons or antiprotons aren't quite doing what you thought they would (and wrangling protons offers a whole host of different challenges from electrons). Or moments where it is realized that the phenomenally complex system of machine and detectors interacts in ways that no one quite expected them to.<br /><br />In the meantime, I hope that the ignorant doom-criers will take a break. I understand that the ethereal reaches of physics are neither easily comprehensible nor of immediate appeal. But I find the fact that every single article I've read on the LHC startup has focused on the fringe element's efforts to spread fear or to shut the project down.<br /><br />People repeat the overused phrase "God particle" like physicist are either a bunch of blaspheming heretics or else expect Yahweh to a appear over the CERN campus near Geneva in all of his billowing-cloud Old Testament wrath. People talk about the whole black-hole thing in a way that implies their only knowledge of a black hole is from the <a href="http://en.wikipedia.org/wiki/The_Black_Hole">Disney movie</a> and that they expect Maximillian Schell and a homicidal robot to pop out of the beams and start sucking the entire planet, Anthony Perkins, Earnest Borgnine, and all, to their doom.<br /><br />To get slightly political, I find this yet another symptom of a creeping acceptance of ignorant mediocrity that has spread to the point that we, at least in this nation, appear to consider flawed normality more valuable and noble than educated eloquence. This anti-intellectualism may well be a globally creeping trend, for all I know, and the anti-LHC ranters are certainly not confined to this nation and much of the outcry over the "Deep Impact" comet probe arose from outside our borders.<br /><br />But this is all beside the point -- if you've been reading this for any time you know my feelings about the conservatism of space exploration (read the <a href="http://noodlebook.blogspot.com/2008/09/my-friends-in-space.html">New Horizons blog</a>!) and pursuit of "safe" solutions rather than ones that run the risk of producing dramatic advances.<br /><br />I want to end on a cheerful and optimistic note so, as I wrap up, let me say this. To all the scientists and engineers at CERN, now the undisputed world center of experimental high-energy physics, I have to tip my hat for your perseverance in getting this thing built and wish you the best of luck in getting it tuned up, fully operational, and producing vital science. I'm <em>very</em> curious to see the results start coming out and, even more, to see Brian Greene write another book about it!Just Nickhttp://www.blogger.com/profile/01845987547854457407noreply@blogger.com0tag:blogger.com,1999:blog-5333608194352082143.post-15567277079215574992008-09-11T07:27:00.001-07:002008-09-11T07:27:50.793-07:00Bike Commuter!As of this morning, I have reached the ultimate level of hippie-do-gooder-earth-loving-corporate-tool: the bike commuter.<br /><br />Now granted, I'll tell you right now that I didn't schlep my wheels onto the train and ride across I90. That's on the plan for spring (or perhaps sooner if some very nice day comes along when I'm feeling adventurous and don't have anything on my calendar at work). What I did was go downhill from my house (which is at an elevation of approximately 250 feet above sea level) to the Edmond's train station which is, for all practical purposes, at se level. The total trip was about a mile, which means an average of a 5% downslope. I probably pedaled about twenty times until I reached the parking lot.<br /><br />But damn you all, I'm going to wear my ankle strap with pride today!<br /><br />That's ankle strap as in reflective-velcro-tie-to-keep-right-pant-cuff-clean and not ankle bracelet as in under-house-arrest-Martha-Stewart.<br /><br />So, from my one mile bike commute, I have the following observations:<br /><br />The Edmonds train station needs a bike rack. I am currently chained to a AC power conduit attached to a phone pole. It works, but feels rather makeshift in this day of REI specialty gear for every application. I figure, however, that the "massive electrical voltage and instant death inside" sticker affixed to the power conduit (I paraphrase) effectively acts as a theft deterrent.<br /><br />Someone would be well advised to make nice dress shoes with Shimano compatible cleats in the bottom. Since it was a short (downhill) ride I just rode on my little stubby pedals rather than bring a change of footwear. We'll see how that goes on the uphill.<br /><br />I need a new coffee mug. The disposable I brought with me from home kept spurting out over bumps despite my best efforts to seek stability. But when you're doing 22mph down a bumpy road coming up on a six lane intersection, coffee (amazingly) takes second priority. I was afraid that my left arm was going to look like the oil stained cowling of some World War Two bomber, what with all the coffee blow back, but in the end the damage was unnoticeable. What's more is how can I claim to my bike commuter green if I'm tossing out my beverage container every day? So now I need a closable, reusable, thermal mug (Erica, should you read this, I'd like to mention the wonderful collection of thermal mugs with witty sayings on them at the new PCC).<br /><br />Riding (on the aforementioned 22mph bumpy downhill and other parts) with my laptop bag over my shoulder and my insulated lunch bag clipped to it turned out to be much easier than I expected. I <em>haven't</em> lost all of that Davis California growing-up-on-a-bike ease that I once had. That felt good.<br /><br />The morning downhill was one of the most peaceful and relaxing times I've had recently. Gulls cawing, ferry boats tooting, the sun gently reflecting off of the clouds. And hardly a car on the road.<br /><br />Cutting the one mile car ride out of my day may not seem like its doing <em>that</em> much for the pocketbook, the carbon debt in particular or the environment in general, the dependance on foreign oil, or any of those other hot buttons. But my dad always taught me that the toughest part of a car's life, from the maintenance, efficiency, and lifespan points of view is that initial startup and first few miles. So though it only saves a little bit, it saves <em>a little bit</em>.<br /><br />If I keep this up (and by that I mean "actually ride back up the hill") I'll start to get in shape in no time -- and then yeah, I90 will be on the menu. Then I'll be sporting the the replica Discovery Channel team jersey and taking advantage of the new company provided bike locker and shower facilities and really putting the package together. Until then, I'm happy to be doing my own little thing, making my own little difference and having some fun on the way.Just Nickhttp://www.blogger.com/profile/01845987547854457407noreply@blogger.com0tag:blogger.com,1999:blog-5333608194352082143.post-82662895222372769482008-09-10T18:02:00.001-07:002008-09-11T06:17:22.337-07:00My Friends (in space)So feel free to hum "My Friends" from <em>Sweeny Todd</em> if you like, but this has nothing to do with homicidally vindictive barbers or straight razors. It is actually a little look at one of my favorite things (if you go over to the right hand section of the blog you'll notice things like favorite calculators and favorite elements and, yes, a favorite space probe).<br /> <br />Today is New Horizon's day in the sun. Which is good, because out beyond Saturn there is less and less Sun to go around. Today we focus on a biography and an explanation of this one little project and its journey to flight and why, exactly, I choose it above and beyond all other comers for the title of "favorite space probe."<br /> <br />I don't want to start by drowning this whole blog in a sea of specifications and technical data -- if you really care about how many milliradians the ifov of the LORRI imager is, look it up. Rather I'd like to start by recounting a rejected name from the day's of New Horizon's development. Apparently naming the damn thing was proving quite a challenge. As I've heard it told, it was almost a case of analysis paralysis, and some interesting candidates were circulating around, mostly tongue-in-cheek. One that actually made a big impression on me was FARR: Finally A Return to Reconnaissance.<br /> <br />Ok, no space probe is ever going to have a name beginning with "Finally" and the crankiness it implies. But there is a message in that name -- for decades we've been going back to revisit worlds already explored to gather more data. Missions have grown more focused on particular themes ("Follow the Water!") or areas of understanding. The approach reminds me a bit of what Hollywood has been doing of late -- remakes, sequels, and adaptations. Don't take the risk (the studios and executive producers seem to think) of going into completely new territory because you might gaffe it entirely and end up with an expensive flop. Instead, pick a relatively well known subject with a somewhat predictable audience and go for that. <br /> <br />There's some legitimacy. I'll go see Ocean's 14 or whatever they are up to now. At least I'll rent the video. My daughter will definitely go see <em>Shreck the 4th</em>. But you know, that first <em>Matrix</em> movie could have been one hell of a flop. And with film budgets what they are now, that thinking is going to force a real drive to conservatism. Plan (1) says you could make $200 million or loose $100 million. Plan (2) says you are almost guaranteed to make $150 million. Bottom line choices make that easy. Balls-out risk takers are rare, now a days.<br /> <br />Spaceflight's gotten the same way, to an extent. We're revisiting worlds we know. We're looking at the details, following exploratory themes. This is great science, and a lot is learned from it. There is, I think, some extra conservatism even within this overall trend to avoid looking directly at the big issues (exobiology is what I'm talking about here) because as long as the big questions are unanswered there is still a chance of flying more missions and learnign plenty about the interesting but undramatic other stuff.<br /> <br />Don't get me wrong. I love this thorough understanding of our neighborhood. I'm more of a deep-space astrophysics guy myself, but Titan, comets, Venus, Mars, Jupiter, Io, all of 'em are fascinating places. And I'm certinly not a fan of the overly-cowboy manned spaceflight program promoted under the Bush administration. But that's another issue.<br /><br />I was raised, however, on the pioneering flights of the Pioneers and Voyagers. I remember staying up until unusual (for a nine year old) hours to watch episodes of Nova or other specials on PBS (channel six!) as the probes encountered Jupiter, Saturn, Uranus, and finally Neptune. I remember that feeling of seeing new worlds and new moons for the first time. The Saturnian system (apparently it <em>is</em> technically accurate to call it Kronian but unnecessarily arrogant to do so) was the most vivid memory, because it really was a special event for a precocious 9 year old with a space infatuation. The rings, beautiful and so much more complex than ever imagined, moons, moons, and more moons, from shrouded and active Titan to icy <br /><br />The robotic engineers at the Jet Propulsion Laboratory were my idols, and the planetary scientists gathering and interpreting the results that these probes brought back filled my imagination the way the tales of Lewis and Clark filled the imagination of boys generations ago. But with that one titanic act of exploration, that once in a zillion chance alignment of the great gas giant and ice giant planets, it was done. We'd been everywhere. It was like the scene in <em>The Truman Show</em> where young Truman tells his class he wants to be an explorer and the teacher quashes his dreams by pulling down a world map and saying (I paraphrase) "It's all been explored!"<br /><br />From this point on, Lewis and Clark could rest at home, take it easy. Follow-on explorers would set about to filling in the details, trading with the natives, exploiting whatever resources they could find, and finally building shopping malls. No wonder Lewis killed himself in the end.<br /><br /><div style="text-align:left;"><img src="http://lh5.ggpht.com/strauss.nick/SMhsxbkLjAI/AAAAAAAAAPU/tgnVbVN4WjQ/pluto_stamp_03.jpg?imgmax=800" alt="pluto_stamp_03.jpg" border="0" width="250" height="177" /></div>But then along comes the chance to go out and explore a new world. One so distant, so remote, and superficially so boring that it had never really been considered for exploration. The gung-ho "faster better cheaper" 1990's begat a few sketches, edge-of-the-envelope designs that pulled out all the stops in an effort to get an ultra-lightweight spacecraft out on a flyby trajectory. PFF, the Pluto Fast Flyby was a poster child for (yet another set of) plans to develop a common set of instruments and back end technologies to facilitate missions to all sorts of cool and exotic places -- Europa, Comets, Neptune, you name it.<br /><br />None flew.<br /><br />Through the fast moving space policy shifts of Reagan-Bush-Clinton-Bush (and a couple of dramatic economic cycles thrown in for the bargain), Pluto missions were on and off and on again in a half dozen different variations. International missions launched by Russian Proton boosters...ultralight weight "twin" missions launched by Titan IV boosters to catch both sides of the planet...and then death. Complete and total demise of the whole Pluto mission thing.<br /><br />In the meantime the planet itself kept getting more interesting. It had an atmosphere. It had a moon. It might have meteorologic or prebiotic processes. We mapped some of its surface features (crudely). Suddenly this pinpoint of light in the distance was a solid world with features of, well, a real planet.<br /><br />Soon the letters started coming in. <a href="http://en.wikipedia.org/wiki/Alan_Stern">Alan Stern</a>, long time Plutophile (read his book!) and a few earnest space enthusiasts kept the dream alive and via the newest tool for space science outreach organized an Internet campaign to revive a Pluto mission. It worked. Congressional fiat inserted (and mandated) funding for a competitively selected Pluto mission. The folks at the Johns Hopkins Applied Physics Lab put forward a proposal -- headed by Stern. JPL put forward a proposal of their own, but I suspect it was mostly just to keep the APL honest. This was Stern's baby, and everyone knew it.<br /><br />He finally settled on a name -- New Horizons -- and so the mockingly appropriate FARR was retired to the mists of history and blogging. New Horizons works -- I grant them that -- and is a proper name and not just an acronym. But I miss something of the spirit of FARR.<br /><br />It took a few years -- and a few near fatal setbacks -- to get the thing on the way. A security scare shut down processing of the Plutonium fuel pellets necessary to keep NH warm and powered. Scrambling managed to get enough Plutonium together to ensure a successful mission. Anti-nuke protesters made desultory threats at preventing the launch -- but other than a few ill-informed crazies and a pacifist grandmother or two, the public failed to mobilize to their cause. The Boeing strike season meant that the workers who would have prepared the 3rd stage motor were walking the picket lines so salaried managers pitched in to ready the motor -- and the protests of the strikers went generally unheard except by the anti-nuke crazies. Winds delayed the first launch attempt. A freakish power outage prevented day two. And clouds almost shut down day three -- until luck and a hole in the weather resulted in one of the most spectacular unmanned launches I've ever seen.<br /><br />Aviation Week's <a href="http://www.aviationweek.com/aw/generic/story_generic.jsp?channel=awst&id=news/010906p1.xml">wonderful article</a> tells the details of the complexity of supporting this little spacecraft's journey. I find the final part of the article -- the throttling profile of the RD-180 first stage engine -- to be particularly telling. Most flights bang the throttle to the stops until the very end when you might start to go easy to avoid pulling parts off. But this flight pushed the profile optimization for every meter per second of delta-V it could generate.<br /><br />Roll back to my <a href="http://noodlebook.blogspot.com/2008/09/why-we-put-rockets-there.html">Why'd We Put the Rockets There</a> post for a video of the NH launch in all of its glory. More thrust than any other current US launcher save the Shuttle. Off the pad like a bat out of hell and from then on, no looking back. <br /><br /><div style="text-align:left;"><img src="http://lh3.ggpht.com/strauss.nick/SMhgSiQgz0I/AAAAAAAAAPQ/MFRtzNeE6eM/New_Horizons_Launch_11.jpg?imgmax=800" alt="New_Horizons_Launch_11.jpg" border="0" width="640" height="426" /></div><br /><br />I'll save the "gee whiz" statistics and <a href="http://www.boulder.swri.edu/pkb/">detailed instrument descriptions</a> for the team's fantastic web presence. In a nutshell the probe is a piano attached to a satellite dish -- a compact body designed to keep heat in and minimize mass attached to the largest dish antenna cheaply available. The radioisotope generator (home of the pesky Plutonium) sticks off to one side to keep its temperature manageable. Gold foil provides much needed insulation so that the waste heat from the electronics and the RTG can keep the vital systems warm, including preventing the propulsion systems propellent from freezing.<br /><br />The science instruments are like the eyes of a lemur, oversize and blinded by daylight, carefully tuned instead to the dark distance of Pluto. A telephoto camera, a multicolor camera, and infrared and ultraviolet spectrometers comprise the primary remote sensing suite. Three instruments record the nature and intensity of dust and heavy and light charged particles as the craft drifts by Jupiter, through deep space and, later, through the Pluto system. Finally the onboard radios play a part by enabling careful trajectory tracking that reveals in detail the mass of objects in the Pluto system and by a clever bit of passive microwave radiometry that helps determine surface temperature. <br /><br /><div style="text-align:left;"><img src="http://lh3.ggpht.com/strauss.nick/SMhtKcuV13I/AAAAAAAAAPY/MtWkYImZ6lE/Picture%202.jpg?imgmax=800" alt="Picture 2.jpg" border="0" width="321" height="225" /></div>The engineering inside the little thermos box of New Horizons is capable of greater autonomy and endurance than any spacecraft before. Indeed it must be -- for the decade long journey would tax the budget and patience of ground crews if controlled in a traditional manner. Electronic and mechanical components would also wear out sooner, so the NH team devised a scheme of "hibernation" where the probe spends the majority of the inflight time with the majority of systems powered down, emitting a low power beacon tone to either reassure controllers that everything is ok or to alert them that there is a problem -- and the need for an intervention.<br /><br /><div style="text-align:left;"><img src="http://lh4.ggpht.com/strauss.nick/SMhtRL3PQ-I/AAAAAAAAAPc/ng4gJ5rD4D8/Picture%201.jpg?imgmax=800" alt="Picture 1.jpg" border="0" width="153" height="323" /></div>Back on Earth, Stern's team has run a model of outlook. Perhaps spurred by the grassroots campaign that helped win the mission its day on the launch pad, they have kept their eye on those of us who follow spaceflight with passion and interest. Pluto's very enigma and extremism helps -- everyone likes a mystery. Members of the team -- right up to Dr. Stern himself -- have made frequent appearances on space news boards like my favorite <a href="http://www.boulder.swri.edu/pkb/">UMSF</a>. In one of the most phenomenal acts of public outreach ever, the team actually accepted the contributions of Internet supporters to the science program.<br /><br />Approaching their encounter with Jupiter, the official science team was busy doing official science -- planning the aspects of the Jupiter swingby that would generate the most compelling scientific data return. Several enthusiasts on the UMSF boards, however, used trajectory information provided by the NH team to simulate in great detail the probe's journey through the complex Jovian system. Using these simulations, they were able to identify a number of "Kodak Moments" as space probe types call them -- the beauty shots of crescent moons, ring systems, and extraterrestrial volcanic eruptions that actually make it in to the newspaper.<br /><br />Since the science team actually had more spacecraft resources than they had time to plan for, they accepted these amateur contributions and, instead of sneering at the part-timers, added the suggestions in to the flyby mission plan. And you can bet which images appeared on the newspaper covers -- not the dull-but-scientific ones, but the glamour shots that those of us out on the Internet came up with.<br /><br />The New Horizons team has also done all the standard things -- a CD carrying names of supporters who registered on the Internet is mounted on the probe (and you can bet that my name -- and the names of those closest to me -- are on there). Podcasts, email updates, and well maintained websites too. And some of the most easily available detailed documentation of a current vehicle I've ever found. They've got the now obligatory Twitter presence (NewHorizons2015, if you want to get the updates) which is pretty chatty right now since the team is working one of the annual checkout periods that will lie between long sessions of hibernation.<br /><br />For these efforts and others, Stern's gone on to become something of a hero (and <em>very</em> occasional email correspondent) of mine, not least for his brief stint as head of NASA's space science division -- a stint that was oddly parallel to my own stint with my most recent employer in timing and apparent motivations for departure. But now he's back at the APL, flying space probes when he can and getting instruments of his aboard nearly a half dozen other flights. NH is the largest ever PI (Primary Investigator -- as opposed to a NASA laboratory) managed space project NASA's ever flown -- you libertarians can think of PI managed missions as sort of like the charter schools of space exploration. Through blunt perseverance, clever engineering, shrewd campaigning, and tight management, it is bringing a little bit of the mystery back in to space exploration.<br /><br />And out there, a billion kilometers away and just beyond the orbit of Saturn, finally flies the return to reconnaissance.<br /><br />By the way, if you want to see some absolutely spectacular photography of not just the New Horizons launch, but several others as well, check out <a href="http://www.launchphotography.com/Launch_Photos.html">launchphotography.com</a>.<br /><br />Just Nickhttp://www.blogger.com/profile/01845987547854457407noreply@blogger.com0tag:blogger.com,1999:blog-5333608194352082143.post-11561747594856139052008-09-05T17:44:00.001-07:002008-09-05T17:44:34.473-07:00Why'd We Put the Rockets There?It happens every Atlantic hurricane season: news reports on all of the popular spaceflight websites about how Hurricane So-and-So delayed the rollout of the Space Shuttle or damaged this rocket on the pad or that important piece of ground equipment. And every year, right around the Atlantic hurricane season, I find myself facing the question: why did the United States put its space launch facilities right in the path of the typical storm track? So every year, just to remind myself that it wasn't a completely ludicrous decision, I go through the physics of the thing.<br /><br />And physics is exactly why the United States sited its primary national launch site on the south coast of Florida. It wasn't that the land was cheap or that a Floridian senator was on the committee or such (these things may or may not have been true, but even if so, they were not the overriding reason).<br /><br />One of the reasons for the birth of the Space Coast down there in Florida is safety. Launching rockets was, and indeed remains, a tricky business. The occasionally go...wrong. Even successful flights shed parts (sometines unintentionally but more often intentionally as spent stages and fairings are jettisoned) And for that reason, it is nice to have a large chunk of empty land that your launches can fly over. And, for reasons that we will shortly discuss, most space launches fly to the East, more or less. That would confine a United States launch facility to the East Coast. Conceivably Hawaii could be used as well, since by the time a vehicle launched from that location reaches any significant land mass, it will be flying high enough as to pose no threat. But flying from Hawaii would raise infrastructure and transportation challenges, particularly in the 1950's when the Space Coast was first evolving. One could argue that the wastes of far northern Canada would be safe to fly over and that Alaska would make a reasonable launch facility -- but in addition to the dangerous politics of arguing that anyone's land mass is insignificant there are some good reasons why far Northern launch sites are not the best to pick.<br /><br />And so now we enter the physics discussion. Before we can go too far, let's pause and think about what a vehicle in <em>orbit</em> is doing. It is going <em>around</em> the Earth at a rate just fast enough to offset gravity's attraction. Objects in orbit are still attracted by the Earth's gravity. It is an easy misconception to imagine that they are some how "beyond" the force of G, but achieving that feat requires a great deal more distance (theoretically an infinite one) and a great deal more velocity. It is just that their motion is such that as gravity relentlessly tries to pull them down to the surface, their own motion offsets the tug -- just like when you whirl a bucket of water, the water's own momentum (as manifested in that handy engineer's shortcut of centrifugal force) holds it in place. In orbit, your whirling velocity around the planet wants to push you off into deep space -- but the attractive force of the massive planet holds you neatly balanced. It is a beautiful thing, really.<br /><br />The operative point, in case you don't want to spend too much time on the bucket-is-like-a-satellite analogy, is that putting something in space really is all about getting it to go <strong>sideways</strong>. Not up. Next time you have occasion to watch a space launch on TV (or in person, if you are so lucky) notice the trajectory. It can be a bit hard to follow since the camera guys always zoom way in, but the Shuttle (or whatever) does not go straight up. After just a few seconds, the vehicle begins to pitch over and fly ever more horizontally.<br /><br />There is a bit of subtlety in the details of the trajectory design, degree of lofting, etc. But the key issue is that a rocket rises <em>a little bit</em> but goes sideways <em>a lot</em>. The first segment of flight is a gradual transition from the vertical (handy for setting things up) where you are climbing out of the irritatingly thick atmosphere to a horizontal motion where you are building up the speed necessary to get your bucket whirling fast enough to offset the planet's gravitational attraction.<br /><br /><object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/ReH5UshnE8o&hl=en&fs=1"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.youtube.com/v/ReH5UshnE8o&hl=en&fs=1" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="344"></embed></object><br /><br />Watch this video of the New Horizons launch and notice how the big Atlas V appears to be pitching over to an increasingly horizontal trajectory. It is hard to notice second-to-second, but over the course of a minute of flight it becomes pretty apparent. For a real dramatic illustration, watch for the jettison of the solid rocket boosters just about 2:20 into the video. Then at about 2:36 the rocket executes a <em>very</em> dramatic pitch-down maneuver to bring the direction of its flight increasingly horizontal. Apparently this pitch down was even more noticeable to observers watching the launch in person -- enough so that it caused some moments of real worry for those who did not know to expect it!<br /><br />As a rule of thumb, it takes a velocity of around 7,800 meters per second (I'm going Metric on you for this one!) relative to the Earth to get something in the lowest possible sustainable orbit (any lower and you will start bumping into enough of the molecules of ethereal atmosphere at that altitude that you'll slow down...and once you start slowing down you hit more atmosphere...slow down more...and the result is obvious). That's awfully fast, and one of the reasons it takes such gargantuan rockets to loft even small payloads is that building up that much velocity takes a <em>lot</em> of energy. As a brief footnote, I'll mention that with practical considerations taken into place, it takes 9,300 to 9,800 m/s of velocity to actually make it to LEO -- the extra is accounted for by aerodynamic drag (100-200 m/s), control and steering losses (200-250m/s), and the losses spent overcoming gravity (the rest).<br /><br />In such a situation, engineers will try to take advantage of any asset they can. Rockets are built light, fueled with the most desperately energetic propellants possible (and historically some very, very exotic and toxic combinations have been experimented with), and shed unneeded mass at any chance possible. They are also almost always launched to the East. Why? Because the Earth turns.<br /><br />Picture a sunrise: in the East. A sunset? In the West. Our planet, in addition to a whole complex series of motions relative to various other bodies in nearby space, rotates around its own axis, turning from West to East at a rate such that it completes one full rotation in 24 hours. At the equator, on the surface, that works out to a speed of about 465 meters per second (just about 1,000 mph). Why don't we feel this? Because <em>everything else</em> around us (air, water, train tracks, laptop computers, coffee cups) shares this motion. Actually, there is an important subtlety at work here: at the poles, we have zero velocity due to rotation, we'd just turn in place. Spin a globe. The equator is blurry fast, the middle latitudes (North or South) move at a moderate pace, and the poles barely seem to move at all. The velocity, at a given latitude, is proportional to the distance around the globe <em>at that latitude</em>. Amongst other things, this causes the swirling interactions of atmosphere responsible for no small part of the global weather patterns.<br /><br />It also provides a powerful incentive for launching rockets to the East, near the Equator. The Earth gives you a boost equal to the rotation-induced velocity of the surface at the latitude of your launch site. At the equator, that amounts to 465 meters per second. At Kennedy Space center, about 28 degrees latitude (of 28/90ths of the way from the equator to the North Pole) this boost is still 450 meters per second. But were I to build a launch pad here in Seattle, at 49 degrees latitude, the boost is only 305 meters per second. If you are curious, the degree of kick varies with the cosine of the latitude.<br /><br />Given the skin-of-your-teeth challenge of getting something into orbit at all, it is not remarkable that engineers have sought to site launch facilities to take maximum advantage of this simple bit of physics. Now a word of warning -- and clarification for any <em>real</em> rocket scientists who stumble across this: I am ignoring polar orbits, sun-synchronus orbits, non-due-east launches, and the complexities of plane change maneuvers. I know. <br /><br /><img src="http://lh6.ggpht.com/strauss.nick/SMHSXVOf0sI/AAAAAAAAAPI/-4dyoaefBJk/atlantisready.jpg?imgmax=800" alt="atlantisready.jpg" border="0" width="210" height="210" align="left" />Launching from Kennedy, at 28 degrees North, provides a boost of 450 meters per second -- about 5% of our total rule-of-thumb velocity increment. For a hypothetical rocket I've been doodling out in the form of a Numbers spreadsheet, this works out to a payload (to low Earth orbit) launching from KSC allows the payload to increase from 7000kg (for a mythical zero-velocity launch site) to 8500kg! This happens for no increased launch vehicle mass, no increased cost, just a willingness to put up with a few hurricanes.<br /><br />I know that I have a good time ripping NASA a new one in this blog (except Alan Stern, and he's no longer with NASA). But this is one area in which I have to say they chose well. Kennedy is effectively the southernmost point in the continental US that has a clear space to the east. It is interesting, however, to look at some other launch facilities in light of this information and to try and understand the rational behind their selection.<br /><br /><img src="http://lh3.ggpht.com/strauss.nick/SMHSbanwytI/AAAAAAAAAPM/dwczuUzDv-A/610x.jpg?imgmax=800" alt="610x.jpg" border="0" width="610" height="421" align="left" />For starters, look at Russia. Devoid of a "space safe" site to the East (almost any Russian East coast launch site would have to fly over Japan), they are forced to launch from the West side of the nation, taking advantage of the vast reaches of emptiness that fill the middle part of Russia. This approach isn't without very serious drawbacks -- spent 1st stages from Russian Proton launchers litter the steppes of Kazakhstan. The toxic traces of the NTO/UDMH propellant that Proton uses have begun leaching into the groundwater supplies with, well, predictable results.<br /><br />Their other launch facilities are all in the far (for a launch site) North and get even less help from the Earth than my mythical Spaceport Seattle. To make matters worse, even when launching Zenit or Soyuz boosters (which generally avoid the toxic-waste-dump problem of Proton) decent range safety practice dictates narrow and oddly positioned corridors through which launches can fly -- dramatically restringing the orbital options available to Russian flight planners.<br /><br />Other launch sites face some even more interesting challenges. Japanese launches often must contend with the fishing season. Plentiful fishing grounds to the East of the launch sites mean that, in an island nation that eats a lot of seafood, space launches must wait until the fishing boats get out of the way rather than imposing an exclusion zone is is done off Florida.<br /> <br />Israel faces perhaps the most challenging geographical launch constraints of anyone. Located around 31 degrees North latitude, things wouldn't seem too bad (not as good as Florida, better than Russia) until the political climate of the region is taken into account. Raining debries from a launch (successful or failed!) down on hostile neighbors to the east poses a grave political risk, and a potential security challenge should any piece fall into the hands of hostile intelligence agencies. There is also the risk of a launch, even announced, over hostile territory being seen as an aggressive act. <br /> <br />What all of this means is that, alone among the space capable states, Israel must launch her satellites DUE EAST -- exactly the wrong direction. Not only do Israili launch vehicles get no assist from the Earth's rotation, but they must actually work to overcome it first! The result is a penalty of about 450 m/s beyond the basic 7,800 m/s required for LEO insertion. Another amusing effect are the unique orbits occupied by satellites launched in this manner.<br /><br />The European Space Agency launches from French Guiana -- from a point only 310 miles north of the equator. This supplies something like 463 m/s of velocity increment. Compared to the launch site in Plesetsk, a Russian Soyuz rocket launched from the ESA spaceport picks up 1200kg of payload to a geostationary transfer orbit. That is an increase of 80% -- though in all fairness the launch azimuths of Plesetsk are particularly poorly suited to this trajectory and the difference for other orbits range down to only 20% -- but still significant!<br /><br />Similarly close to the equator is the very clever Sea Launch platform and rocket. This is essentially a Russian Zenit rocket mounted on a converted oil platform that migrates down to sit <em>right</em> on the equator for launch. The result is the full 465 meters per second of possible rotational kick -- and freedom to launch on whatever azimuth or pathway is wanted!<br /><br />So hurricanes are not, I suppose, such a bad price to pay.<br />Just Nickhttp://www.blogger.com/profile/01845987547854457407noreply@blogger.com0tag:blogger.com,1999:blog-5333608194352082143.post-39450030636179192822008-09-05T06:55:00.000-07:002008-09-05T17:43:59.303-07:00Whither the Rifleman?Ever notice how often I start things with <em>whither</em>? Great word. Technically it is an interrogative meaning "to where" or "to what state" but the fact that it sounds so much like <em>wither</em> gives this wonderful sense of mood and foreboding.<br /><br />A couple of recent events, globally and personally, got me applying wither to war and to the role of the rifleman, the guy with the gun, the man on the front lines. They got me thinking on this topic not in a "build a world beyond war" sort of sense -- I'm much too practical and cynical to believe that conflict, armed or otherwise, will ever cease between people, peoples, and nations. And I appreciate the value of a strong and solid defense, that much is for sure. Instead my musings were (and still are) in an operational sense -- given the current and projected future political and economic climate in the world, what sort of conflicts are likely and what sort of roles should we expect our military to play in them? And, taking it to the next and (personally) more interesting derivative, how do we organize and equip our military to respond to those challenges?<br /><br /><img src="http://lh4.ggpht.com/strauss.nick/SMHGqMd6N1I/AAAAAAAAAO8/omjgZ4O9IlM/800px-MQ-9_Reaper_in_flight_%282007%29.jpg?imgmax=800" alt="800px-MQ-9_Reaper_in_flight_(2007).jpg" border="0" width="400" height="265" align="left" />The first thing that got these musings started was an article in Aviation Week that a <a href="http://www.aviationweek.com/aw/generic/story_channel.jsp?channel=defense&id=news/MQ9082508.xml&headline=Unmanned-On-Unmanned%20Combat%20Emerging%20In%20Iraq">USAF Reaper UAV</a> (drone, if you're not down with the aerospace lingo) dropped a bomb on an explosive carrying remote controlled car in Iraq. The first thought, based on the remote controlled car thing, was of the two brothers from the cast of <em>Ocean's Eleven</em>. But then the story percolated and the true point of it hit: one robot attacked another.<br /><br />Now let's be far and stop preparing for the Rise of the Machines. Both vehicles were <em>remote controlled</em> -- that's a far cry from SkyNet and the Terminators. A crew, probably in Langley Virginia, was controlling the Reaper via a satellite link and another crew, probably standing by the side of the road, was controlling the bombed-up Iraqi SUV. Come to think of it, this has got nothing at all on <em><a href="http://en.wikipedia.org/wiki/BattleBots">Battlebots</a></em>. Well, except for the fact that the one remote control robot thingy was trying to kill people and the other remote control robot thingy was linked via satellite to a station half way around the world and dropped a 500lb laser guided bomb on the first remote control robot thingy.<br /><br /><img src="http://lh3.ggpht.com/strauss.nick/SMHHZH4lbUI/AAAAAAAAAPE/YMNsILL10R8/Picture%201.jpg?imgmax=800" alt="Picture 1.jpg" border="0" width="386" height="434" align="left" />Never the less, this illustrates one of the projected directions of modern air war. Un-crewed (we don't say "unmanned" any more) air vehicles have the wonderful ability to stay on scene for hours and hours and hours -- days even. A Reaper can loiter for NN hours, a Global Hawk for 40 to 48, and that latter figure after flying a 3,000nm round trip from home field to target area. This kind of sustained presence is invaluable in brining the areal perspective to the kind of fight going on in Iraq and Afghanistan. The traditional fast mover can offer little but <em>responsive</em> firepower -- heading in from a loitering point when called for by guys on the ground and depending on them for direction and guidance. Even maintaining that kind of ability -- a "cab rank" of close air support -- requires a couple of dozen aircraft in the field, tankers, and a rotating (and expensive) presence.<br /><br />Given the proliferation of MANPADS (MAN Portable Air Defense Systems -- here it is OK to be sexist and assume the shooter is a guy) there is also a vast risk in having a two of four ship of F-16's hanging around in the skies near target-land, even if the airspace is nominally under friendly control. This is particularly true when the airspace is more heavily defended, less nominally under friendly control, or is airspace that isn't supposed to have any of our guys operating over it in the first place.<br /><br />Right now, the use of UAV's as a surveillance and targeting tool (robot vs. robot or robot vs. human) is confined to the tactical -- to supporting troops on the ground, watching convoy routes, and patrolling cities looking for characteristic acts of bad-guy behavior. The weapons employed have typically been in the "lightweight" category: Hellfires and 500lb bombs and a lot of attention is going to even lighter weight weapons like the very clever Viper Strike to enable close-in drops.<br /><br />But many analysts (including myself) see a future where persistent uncrewed surveillance and targeting assets mix with stand-of missiles to combine near-real-time covert operation with the sort of hard-hitting punch traditionally associated with manned aircraft and, in particular, strategic assets. Which is talk-around speak for B-52's, B-1B's, and B-2's. Granted, a single B-2 can drop something like 16 2,000lb bombs -- and it'll take a lot of missiles to equal that kind of warload. And I'm not going to get into the economic argument of 1 B-2 bomber vs. 200 Tomahawks or such -- because that sort of argument will go back and forth until the cows come home since the numbers inevitably involve a considerable amount of speculation and how-much-a-human-life and where-do-you-draw-the-line logic (which allows them to be tweaked to say whatever you want them to...).<br /><br />And that's not the point of this blog entry, either. The point -- or at least a stepping stone -- is that I see air combat increasingly the domain of the uncrewed vehicle. Some roles will remain crewed: big assets (bombers), for example, will long continue to have people in them -- putting someone inside an asset of that power (and expense) creates a warm fuzzy feeling of control and responsibility. But you get the point.<br /><br />The second thing that got me musing on this particular path was the long-delayed fruition of some Internet research. Sometimes things on that fabulously interconnected collection of information go that way: you start looking for something, fail to find it, give up, and three months later find it purely by accident. Perhaps it got posted while you weren't looking. Perhaps someone else found it and put a link someplace you just happened to be looking. Perhaps you subtly shifted your Google search terms just enough to get the right result this time. Anyway, because of this phenomena, I sometimes go back and start tossing out a few searches for questions I'd been trying to answer but had to give up on.<br /><br />A couple of weeks ago one of these bore fruit. I've long had a fascination with military organizations -- the structuring of military forces to cope with the expected (and unexpected) trials and tribulations of deployment and combat. It is an optimization puzzle -- given a constrained number of people (and money and other assets), how do you best arrange things to bring effective, robust, and sustainable combat power to bear? Philosophies on these organizations shift about every decade or so as the conflicts underway in the world shift from one sort to another. As the NATO armies began to see their roles changing from that of a Cold War roadblock against the Soviet Union to that of flexible, transportable intervention forces, they had to do some hard re-examination of force structures. As the U.S. Army increasingly found itself fighting a long-lasting counterinsurgency as opposed to a fast-moving war of maneuver, it had to do some equally dramatic re-examination of force structures.<br /><br />As you can imagine, this is a big time of self-examination for the world's armies. Those not directly involved in a fight somewhere are watching and learning lessons and trying to forecast the next fight and therefore, the next round of organization and equipment. So a lot of armed forces are going through periods of structural change -- and change is always disturbing for the changee but interesting and illuminating for the observer. Different organizational approaches and different concepts of restructuring can reveal a lot about the underlying philosophies of the force in question and the operational history through which it has evolved.<br /><br />This isn't an examination of different TOE organizations or what they mean about the culture of a nation or a military. Suffice it to say that I was having fun looking some over. The unavoidable realization is the continued presence of infantry. Tanks have grown from odd curiosities through charging Blitzkrieg cavalry to indispensable support weapons. Missiles, machine guns, and mortars have expanded to populate units ever more thoroughly and diversely at the squad, platoon, company, battalion, and brigade levels. But there at the heart of it remains a collection of guys with rifles.<br /><br /><img src="http://lh6.ggpht.com/strauss.nick/SMHGidwTu7I/AAAAAAAAAO4/qkHs093sKkk/mt_newirr_700_070326_287.jpg?imgmax=800" alt="mt_newirr_700_070326_287.jpg" border="0" width="287" height="195" align="left" />Only the guy-with-rifle can clear a stairwell without blowing up the building. Only the guy-with-rifle can rifle through the papers in a bomb-maker's hide looking for contacts. Only the guy-with-rifle can snap interconnected zip-ties across someone's wrists and send him back across the lines. Only the guy-with-rifle can man a roadblock or walk the streets on a dismounted patrol. Only the guy-with-rifle can use his wits and his skill in their purest form to go, see, and report with an intimacy with which no sensor package can compete. And, in the nicer side of the military, only the man-with-rifle can put down that gun and unload supplies or build schools or clear rubble or help the wounded or any of those humanitarian moments.<br /><br />Only he possesses that unique flexibility and adaptability of the human.<br /><br /><img src="http://lh6.ggpht.com/strauss.nick/SMHG6o1mCSI/AAAAAAAAAPA/WtPNmdKwU28/unitprofile1a.jpg?imgmax=800" alt="unitprofile1a.jpg" border="0" width="300" height="180" align="left" />Any given guy-with-rifle might now carry a personal radio and GPS receiver, a laser rangefinder, night vision gear, and a short range guided missile -- all gear inconceivable as personal equipment even twenty years ago. His rifle might have a laser spot projector for nighttime target marking, a flashlight, a grenade launcher, and a 4-power scope clamped and strapped to it. He may wear protective gear offering protection unheard of to previous generations of soldiers. But all of this goes to underscore not his budding obsolescence at the hands of impending robotic marvels but rather continued -- or even increased -- importance.<br /><br />All these marvels have served to distribute the fight in ways never before imagined, each rifle team's scope of responsibility filling an ever larger circle of geography and threat. And as the infantryman finds himself lugging ever more equipment to confront ever more diverse threats, he is again forming the heart of the world's armed forces.<br /><br />Reviewing the new organizational structures -- either in place or in the works -- all show a shift in the expected focus of the fight from the rolling armored warfare of a NATO vs. Warsaw Pact fight or Operation Desert Storm style towards a tighter grinding battle more akin to what was seen in Bosnia or Iraq. The expected degree (and nature) of cooperation between those long time rivals of the ground fight, the tanks and the infantry, is an interesting thread to follow in trying to understand these shifts.<br /><br />These military organizations that are heading into the second decade of the 21st century each show some degree of revision in the thinking about how these arms should cooperate. You don't have to be a military analyst to see how awkward a tank can be moving down a city street and yet how devastating a single shot from a 120mm main gun is when confronted with a sandbagged machine gun post that could hold a company of infantry off for hours. And so the armies of the world progressively push the armor-infantry cooperation ever further down the chain of command.<br /> <br />The rifle platoon has long been the sacrosanct heart of the United States Marines, and that particular force cross-attaches so vigorously that a platoon commander could well find himself with tanks, armored transport, heavy machine guns, ATGMs, snipers, or mortars seconded to his direct control. Nothing here is changing -- conditioned by the intimate island fighting of the Pacific, the Marines have never lost sight of their vision as a rifleman-centered force. Tank and Amtrak battalions have always expected (and trained) to be carved up and subordinated to other units for employment in battle. This particular willingness to play mix-and-match with forces from widely separated branches of the force has long been a uniquely Marine style of operation. Coming from the mindset of an intervention force, rather than an anti-Warsaw-Pact roadblock, they have long fostered creativity and versatility. And, it almost goes without saying, a foundation based on the small unit of riflemen.<br /> <br />The new "square" organization and increasingly "combined arms" structure of the US Army's Armored Brigades shows a clear migration towards a infantry-armor balance. In the brigade, two identical combined arms battalions each contain two tank companies and two mechanized infantry companies. The US Army has never regularly brought the combined arms of armor and infantry together in a unit as small as a battalion before (excepting cavalry organizations, by the way). The two-by-two structure also displays an expectation of the tank and infantry forces as a fighting team, mutually supporting each other to deal with urban obstacles, enemy fighting vehicles, close-in threats, and the maneuver fight.<br /> <br />The French army's new structure looks positively gothic and incomprehensible -- and trust me, I've spent plenty of time trying to wrap my thoughts around it. In addition to a smorgasbord of tactical options at every level, it showcases a unique in-between regimental structure for the Leclerc tank force. Thin on support and supporting arms at the upper level, this structure seems to push reconnaisance, fire support, and combined arms down to the company level in a way that defies understanding. Until, that is, the armored regiment is viewed alongside the two infantry battalions that join it to make up a French battalion (I told you it was almost incomprehensible!). Then the thin-at-the-top, heavy-at-the-bottom structure makes sense. The tank regiment itself is a skeleton force that exists only for training and administrative purposes (plus the rare open-field engagement, one could suppose). When deployed, it would be expected to disperse under the operational control of the two rifle battalions, taking its decentralized supply and maintenance resources with it.<br /> <br />Even the Germans, long a panzer-centric force of armored mobility, are starting to change. The Heeresstrukturs of old emphasized infantry as a supporting arm, screening for the armored spearheads, holding territory after an advance, playing at ambush in withdrawal. But now, increasingly aware of NATO's role as a stabilizing and intervention force, the Bundeswehr is fattening its rifle platoons from a scarecly usable eighteen dismounted troops to an at least marginally effective twenty four. Tank and rifle companies now follow exactly identical structures, intended at least partially to enable routine cross attachment down to the platoon level. The equipping of a significant percentage of their fabulous Leopard 2 tanks with dozer attachment further leads to an expectation that the armored arm would accompany the infantry as an integrated anti-obstacle force. Furthermore, the latest couple of iterations of German army structure (going back to the 1990's) have shifted from the three-tank platoon in their armored units to the four tank platoon. The former has been found optimum for use in tank-on-tank engagements (particularly in open terrain). The latter, incidentally long used by both the US Army and Marines) is much better in a supporting role or urban fight -- the four tanks split into two pairs and can continue to provide mutual support where a three tank unit would either be overkill and hingly cumbersome or leave one orphan tank off (and highly vulnerable) on its own.<br /><br /><img src="http://lh5.ggpht.com/strauss.nick/SMHGHIdzRYI/AAAAAAAAAO0/aFKjnkIn9DI/LAND_M1s_3-ID_Iraq_Tal_Afar_lg.jpg?imgmax=800" alt="LAND_M1s_3-ID_Iraq_Tal_Afar_lg.jpg" border="0" width="400" height="265" align="left" />All of this makes one thing clear -- the rifleman is here to stay. The reasons for this emphasis shift are obvious -- increasing expectation of urban fighting, prevalance of counter-insurgency fighting, peacekeeping operations where forces work close to the civilian populations rather than in an open field battle -- are obvious and clear to anyone who watches the news. Tanks are retreating from their role as the unstoppable bohemouth's of the battlefield back to the role of supplying escort, protection, and covering fire for the infantry for which they were originally concieved. Air power is threatening to obsolete itself, metamorphosing (at least partially) from resplendant knights of the air into remote control spotters sitting in air-conditioned control vans thousands of miles from conflict.<br /> <br />And through all of it, the most intimate core of combat remains.<br /> <br />Two quotes. One is a half-remembered paraphrase from (I believe) a former commandant of the US Marines. The other is from Mick Jagger. Go figure.<br /> <br /><em>The most powerful force on the battlefield is a single man with a rifle.</em><br /><br /><em>Say a prayer for the common foot soldier.</em><br /> Just Nickhttp://www.blogger.com/profile/01845987547854457407noreply@blogger.com0tag:blogger.com,1999:blog-5333608194352082143.post-37629444796126516752008-08-27T22:09:00.001-07:002008-08-28T16:56:13.811-07:00BarstoolsThis post is going to make me sound like an alcoholic if I'm not careful. But the thing to remember is that this is not a blog about drinking, or indeed about bars. Rather it is a blog about a particular arrangement of people, furniture, and objects.<br /><br />That said, drinking <em>will</em> figure in to it, but feel free to make that coffee, water, or a smoothie if you prefer. Move it out of a drinking establishment and into a coffee house or <br /><br /><img src="http://lh4.ggpht.com/strauss.nick/SLYq4o7X4qI/AAAAAAAAAN4/sB2DiRHGC1I/Picture%203.jpg?imgmax=800" alt="Picture 3.jpg" border="0" width="129" height="231" align="left" />What, in my roundabout way, I am trying to get to is this: I love sitting on a barstool, at a bar, watching the world go by (or participating in it -- barstool does not mandate or even imply passivity). The personal geography of the stool and the bartop are nearly perfect. A great height (if it is not too tall) for working on laptop. A great height for a book or magazine or some old fashioned pen-and-ink notepaper. There is enough space to spread out -- but not so much as to enable uncontrolled sprawling. A plate, a drink, and a book/laptop/magazine fit perfectly. This forces a tidy work habit and the selection of essential resources. The height of the surface also enables a pleasant multitasking -- the sharing of time between food and drink and whatever form of work (or recreation -- for a laptop computer or a book or some notepaper could imply either for me) is at hand.<br /><br /><img src="http://lh6.ggpht.com/strauss.nick/SLYvU_rgn8I/AAAAAAAAAOE/5E25w7B5r4E/Picture%205.jpg?imgmax=800" alt="Picture 5.jpg" border="0" width="110" height="70" align="left" />But almost all of this could happen at a table. The relationship between the tabletop and the body is not too different from that between the bartop and the body. But it is a significant difference. The bartop encourages a leaning, relaxed, elbows-on-the-table mood. The <em>table</em> is a rigorous place, both by arrangement and psychology, where posture must be maintained, children should be seen but not heard, and knife and fork must be used properly.<br /><br />There is something else about the bar that works well, and that is the back bar and the (almost) inevitable TV playing the news or a sports show. First, the back bar, that glorious collection of multicolored, multistyled bottles against a mirrored backdrop. Cognacs, Scotch whiskies, and super-premium vodkas and bourbons on the top row. Then the blended whiskies, the more commonplace vodkas and bourbons and a necessary range of tequila. Finally, one step above the well, the more ordinary vodkas and rums as well as the additives: the vermouths and the liquors. <br /><br />I'll admit, right now, that <em>your</em> favorite bar may not exactly mirror that arrangement. This is just (roughly) how I'd do mine.<br /><br />It is a wonderful visual stimulus -- something to gaze at when you need to look up. Unlike other diners across (or at an adjacent) table, it never looks back (if it ever does, seek help). Unlike an office wall, it is more than eighteen inches away and gives your eyes <em>some</em> sort of a break from the relentlessly myopic staring of the modern knowledge worker.<br /><br />The TV plays the same role. A quick look away to Larry King or Wolf Blitzer or Keith Olbermann can refresh a stuck thought process or just provide a break from a monotonous task. The intermezzo of a highlight reel can provide a quick break between catching up on work email and diving into the framework of an intricately planned project.<br /><br /><img src="http://lh3.ggpht.com/strauss.nick/SLYrdaivc1I/AAAAAAAAAOA/hwBawtMzAd0/Picture%204.jpg?imgmax=800" alt="Picture 4.jpg" border="0" width="139" height="346" align="left" />And here, for the first time, we will also encounter the alcohol. From ancient Sumer on, people have found that properly treated fermented grains can produce a relaxed state, inducing of creativity, conversation, risk taking, and even, in the right situations, considerable productivity. In the classic pattern of the "if you mean whisky" fallacy, it can also produce excessively abrupt emails, poor proofreading, a tendency for summary resignations, misuse of Britney Spears crotch shots in PowerPoint presentations, and worst of all corporate Karaoke. But a little self restraint, here, and the benefits out weigh the risk of accidentally showing board members a photograph of Brit's underwear.<br /><br />Here is a place where you can sit and work and take a moment to rest and someone will bring you (almost) everything you need. What, then, of the noise and the other people there? For starters, I'm the kind of guy who has no problem grabbing a spot at the bar, pulling out his laptop, ordering a beer, and getting to work. If the rest of the patrons are all meeting up and actually <em>watching</em> the game or flirting, so what! If they think I'm an oddball, then that is <em>their</em> problem and not mine -- and if you are uncomfortable with this sort of attitude then you might actually find this whole working-at-a-bar thing isn't for you. But read on, we'll get on to this interpersonal contact stuff soon enough.<br /><br />The crowd, though, becomes another optional distraction, something to take your interest away when you need (or choose) to let it do so. The rest of the time, it is white noise. Stare at an overly complex scene -- say one of those ultra-hard German crossword puzzles based around an oil painting of a cluttered used bookstore or else a day care center. Then let your eyes loose focus for a moment and suddenly the visual stimulus retreats to manageability. Crowd noise does the same thing. It <em>helps</em> focus by forcing you into yourself. And when you want to, look at the bored girl and the desperate guy hitting on her, or the bachelor party group, or the silent couple, or the would-be executives or... And if you catch enough of one of the conversations, and it should be sufficiently close by, say hi, drop in, offer some advice, tell them the easiest way to the freeway or what you thought of <em>Mama Mia</em>. It is (to gracefully paraphrase <em>Fight Club</em>) a single serving friendship. If you laugh and they laugh, great, everyone wins. If you laugh and they laugh -- at you -- then at least you brought a little joy to the world and you will <strong>never meet these people again</strong>.<br /><br />But we do not always come to bars solitary, with laptop. Sometimes we come with another person or even a people. And then the whole barstool thing takes on a new role. It is splendidly isolating -- the crowd noise again. You can say anything, things you wouldn't say at a quiet restaurant, things about each other and what you'd like to do later, things about your friends, things about your co-workers, the economy, or the Large Hadron Collider. Which, by the way, will completely fail to destroy the Earth or even the universe when it switches on. The Large Hadron Collider, that is. But when the things to say run out or need refreshing, there is the full spectrum of human drama there, from the TV screens to the other patrons (tastefully watched in the back bar mirror if there is one). Take a break, look around. <br /><br />The posture -- remember the posture? Perch in couples holding hands, turn your wonderfully swivelable barstools towards each other for intimacy, turn back to the bartop for food or to read the menu or new magazines or to stare at the liquor bottles. If you are there in a group, lean in, lean out, arrange yourself as needed to talk to the person next to you, or n+1 spaces away. Raise your voice if necessary, scrum together as four for a laughing and shouting shared comment. Its all good, it all goes.<br /><br />When you're on a barstool.Just Nickhttp://www.blogger.com/profile/01845987547854457407noreply@blogger.com0tag:blogger.com,1999:blog-5333608194352082143.post-18640825630337602122008-08-26T16:52:00.001-07:002008-08-26T16:52:03.003-07:00(Aero)space is a Harsh MistressQ3 has not been pretty for the little guys in aerospace.<br /><br />First Space-X looses their third Falcon 1 rocket.<br /><br />Thilert proves that corrupt and fraudulent management and leaving your creditors and customers in the lurch is not an American speciality but rather that the Germans can do quite well at that game too.<br /><br />Grob, to absolutely no one's surprise, files for insolvency and protection after managing to fatally crash the prototype of an already underfunded and overambitious project.<br /><br />Columbia Aircraft's subsumation into Cessna (or did that happen in Q2?).<br /><br />A few other dreamers fell by the wayside, too, unnamed and already forgotten.<br /><br /><img src="http://lh3.ggpht.com/strauss.nick/SLSV8Y3pY0I/AAAAAAAAANk/0tMd_1x80wA/Eclipse500_credit_Declan_540x359.jpg?imgmax=800" alt="Eclipse500_credit_Declan_540x359.jpg" border="0" width="270" height="180" align="left" />And then finally there has been the slow, bitter meltdown of Eclipse Aviation. At some point, I stopped believing and saw this as something that was bound to come. But not always. Five years ago, Vern's promises sounded good. Revolutionary, almost. A personal jet, a family flivver of the air. At long last Lewis Black and I would have our flying cars.<br /><br />The marketing materials made that little jet seem so much like that vision of the future. Not quite <em>The Jetsons</em> but pretty damn good. In the post 9/11 world of increased aviation security it seemed like a great idea to get the heck out of the controlled gate-check world and start flying via air taxi or personal jet. The milage was even pretty good -- and the price? Fantastic.<br /><br />The prototype flew -- did about one turn through the pattern from what I gather, and promptly landed. The engine, Vern insisted, was to blame. I'm willing to believe them. If Williams had, in fact, not completely failed to produce a viable super-mini turbofan then someone else would be trying to put that powerplant back into the air. How's that for a sentence construction, eh? But the FJ22 appears entirely moribund, off the website, almost a memory. Like Keyser Söze, perhaps the FJ22 is now a spook story that jet propulsion engineers tell their kids. Over reach the state of the art...and the FJ22 will get you!<br /><br />It would not be fair to forget about this debacle of the powerplant. Ever revolution in aircraft design has been preceded or accompanied by a similar advance in engine technology. Without Williams' promised miracle, a quick substitution had to be performed in the form of Pratt & Whitney Canada's glorious little PW610. This was also a baby -- not quite the super-midget of the rejected motor, but still going deeper in to miniature-jet-engine technology than anyone (certainly anyone with the cred of P&W) had gone before. The timing was perfect, even though the fuel consumption, weight, and cost were all going to be higher.<br /><br />Now I'm not going to let anyone start to toss a bunch of blame onto Pratt & Whitney. There's a genetic thing at work -- my grandfather would pretty much only fly things with P&W motors in them, possibly for superstitious reasons, but the point is the same. They build tanks. P&W Canada's been building miniature turbines in the form of helicopter engines since the 1950's and probably has more operational experience with this size class of jet than all the rest put together. So they know of what they speak and, while the end result may not have been quite as spectacular as was hoped for, it remains an excellent motor.<br /><br />And perhaps more to the point, the press out of Eclipse was confident and smooth. The new engine would have greater thrust (a feature!) and only slightly higher fuel consumption (a bug) requiring tip tanks (that, I believe, had been planned anyway). No problem, a bit of a delay, just a flesh wound, everything is fine. Flight testing pretty much ground to a halt until a series of design revisions produced more production-like prototypes. These, in due time flew, obtained certification, and appeared on a lot of magazine covers.<br /><br />And then things started to get a little icky. Customers were obtaining their jets, but with some of the much-vaunted Eclipse features omitted. FIKI (Flight Into Known Icing) certification seemed to draw on forever. Avionics features were placarded <em>off</em>. Blown tires started to become a frequent occurrence (Eclipse blamed operator error but I don't need to spend much time pointing out that a systemic spike in a particular sort of operator error can point to a design flaw that encourages this error...). <br /><br />Then things got weird. Eclipses were going to be built in Russia. The single engine Eclipse 400 started playing the air show circuit. The hyped avionics architecture was being scrapped in favor of a less integrated system including a couple of off-the-shelf Garmin units. Blogs and chat rooms populated by frustrated, venting customers faced unprecedented legal threats. You'd think that one of the landmark cases on Internet anonymity would revolve around some huge megacorp, but apparently Amazon and Microsoft and General Motors and Delta Air Lines know well enough to let cranky customers have their space and not try to shut them down.<br /><br />I wonder if they'll try to shut down this blog?<br /><br />Then, in a so-shocking-it-wasn't-shocking move, Vern Raburn the founder, mouthpiece, and driving force of Eclipse was gone. Forced out by investors. He was to be in charge of "internationlization of production" or something like that. The Russia thing, in other words. Then 100 temps got pink-slipped. Then Vern was gone -- completely. Then a few hundred more got their thank-you-and-goodby (and not all of them temps, I hear).<br /><br />Now the FAA is conducting a review of the certification process to ensure that the E500 is, indeed, fit to fly and (perhaps more to the point) that the agency followed its own procedures and didn't, like a lot of us, get a bit too excited reading the marketing white papers.<br /><br />Alright now, this isn't a history lesson or a debrief. I'm not an aerospace engineer or a business analyst but I know a little about both fields. I <em>am</em> a blogger, and therefore have staked out my little piece of the Internet, opinions and all. Eclipse may pull itself together. God knows, when I was among the 25% of Amazon.com staff who got their notice one February afternoon seven years ago, I knew that they were making a necessary move. So this double-pass downsizing at Eclipse may be just such a necessary consolidation of forces. But Amazon was a hugely successful company -- one that had built success by throwing resources (mostly people) at problems and which needed to adapt to a sustainable, profitable architecture. They made the hard choices and <em>did</em> re-architect into something that is doing very well now.<br /><br />Well, this is a history lesson and a debrief in another sense. I find myself, for the second time in less than a month, writing about over-promising aerospace revolutionaries. I find myself thinking about the seduction of a "better way to do things" and the danger of ignoring the lessons of history. Vern and Elon both <em>knew</em> that the established players were doing things wrong and that they could do it in a different way. So they built teams of like-minded individuals -- doubtless very talented teams with excellent theoretical and practical backgrounds.<br /><br />I've been part of such teams -- and the Amazon.com thing is going to have to come up again. They/we were a team of folks with brilliant qualifications -- vastly over qualified in many cases -- but just little enough experience to <em>not</em> know that we couldn't do what we are doing. Yes, by the way, I know I'm really working the multiple-negatives here. And yet there was a solid business plan and vision lying on top of all of that. There was a solid financial base -- willing to give enough rope (particularly early on) to run at a staggering loss for a staggeringly long (but ultimately necessary) time.<br /><br />I used to have a little saying, back in those days, about why Amazon survived when so many struggled and died: some Internet startups were begun by people with good business plans but little grasp of the technology. Others were the products of people with good technological backgrounds and innovative ideas -- but a flawed understanding of the business world. Naturally, there were a few that failed in both regards -- but they didn't usually make it long enough to discuss. Amazon, by contrast, was one of the first (and now the few) to combine a solid business plan with solid technology. Through ups and downs, bad decisions and good decisions, they held close (enough) to the original vision, adapted when necessary, and managed to make it work.<br /><br /><img src="http://lh3.ggpht.com/strauss.nick/SLSWz0Q7L4I/AAAAAAAAAN0/EmGvRsk_sCg/800px-Eclipse_aviation.jpg?imgmax=800" alt="800px-Eclipse_aviation.jpg" border="0" width="800" height="600" align="left" />And now back to Eclipse (and perhaps Space-X). Where is the flaw? Business plan? Technology? Both? Neither? I lean to both -- a technological product that was designed with enough giddy naivety as to be brittle and intolerant of setback and failure -- the failure of the FJ22 and the original avionics system -- and enough cut corners as to generate problems once in service. A business plan that depended on successes in volume production and demand generation that have, so far, eluded them. Eclipse isn't the first to fall to this error -- of assuming or expecting a demand that fails to appear. McDonnell (now Boeing) made the same sad error in planning the Delta IV rocket. Externally a beautiful vehicle, the Delta's approach to cost-effective launch pricing was based around generating a large demand and benefitting from economies of scale in production and launch. For various unfortunate reasons, this failed to appear.<br /><br />So now how do I wrap this up? Eclipse has problems -- big problems. I don't think that their layoffs are that sort of "thinning the herd" that can bring a troubled company back. They made big promises and generated and promulgated a lot of enthusiasm. So should we fear companies or products that generate too much enthusiasm? "Woah, there, let's not get too excited..." Should we mistrust companies that promise great change and revolution? <br /><br />Any of these ideas are naive and simplistic. The reality is, yet again, <em>caveat emptor</em>. When dramatic promises are made -- read the fine print and run your own numbers. When someone promises just a little <em>too</em> much more than everyone else -- make sure you understand how they plan to (or already have) achieved this.<br /><br />And be sad, at least a little sad, that promise has once again faded into cynicism, layoff, and frustration.<br /><br /><img src="http://lh4.ggpht.com/strauss.nick/SLSWg8IwZ8I/AAAAAAAAANs/JcMTJ_PmpTA/SJ50_2.jpg?imgmax=800" alt="SJ50_2.jpg" border="0" width="250" height="133" align="left" />Cirrus is out there, with a successful line of piston singles and a sexy little jet on the drawing board. Cessna's managed to keep true to their word and move from strength to strength -- including the wonderful little Mustang that just might have contributed more than a little to Eclipse's troubles. Orbital is building a larger-yet rocket from their well understood and consolidated base. So the startups can continue and grow secure. The big guys can show some flexibility and innovation.<br /><br />So a little sad, but not too much.Just Nickhttp://www.blogger.com/profile/01845987547854457407noreply@blogger.com2tag:blogger.com,1999:blog-5333608194352082143.post-64820536101428549452008-08-22T14:37:00.001-07:002008-08-22T14:37:48.711-07:00Desert Island BooksThis goes back to the style of 105 Things About Me -- a self-indulgent look at, well, myself. Not quite myself -- but instead at one of the best ways I've ever found of getting a look at a person from the outside: the books I read. It is, then, half self-indulgence and half suggested reading.<br /><br />I used to listen to a radio station that played the seminal "Desert Island Discs" program. Well known (or as the show wore on, progressively less well known) artists would list the ten disks that they would, if trapped on a desert island, want to have with them. I don't listen to all that much music, and my tastes are with little exception confined to relatively mainstream singer-songwriter stuff.<br /><br />If trapped on a desert island, then, what ten books would I take? I'll admit to a certain degree of practicality: I've opted for long books and books with a high "contemplation" value. I've kept in mind the idea that this reading list will potentially have to tide me over for a while and have included a bit of variety even if that action meant I'd have to leave a couple of strong favorites at home. There are, however, a couple of emotional inclusions, books in there because they should be or because I know they bring me an odd sort of comfort.<br /><br />I'd also like to apologize to the people at Amazon.com for, in some cases, borrowing their cover art in order to make this article have some visual appeal. For what its worth, those pictures all link back to Amazon if you are interested in exploring one of the titles a little further.<br /><br /><strong>Neuromancer</strong><br /><img src="http://lh3.ggpht.com/strauss.nick/SKV7-mvPUQI/AAAAAAAAALo/FvkRy42Kd3w/51A1HJ0GVYL._SL500_BO2%2C204%2C203%2C200_PIsitb-dp-500-arrow%2CTopRight%2C45%2C-64_OU01_AA240_SH20_.jpg?imgmax=800" alt="51A1HJ0GVYL._SL500_BO2,204,203,200_PIsitb-dp-500-arrow,TopRight,45,-64_OU01_AA240_SH20_.jpg" border="0" width="240" height="240" align="left" />You knew this would be in here. This is, without a doubt, <em>my book</em>. It is the book I take with on airplanes, read about every year just to keep in touch, write essays about when I can't think of anything else. It is the drug soaked future vision of techno-hippie-curmugeon William Gibson. As the product of a man with more experience with psychedelics than CPUs, it is in many ways a shockingly prophetic vision of the future. Granted, the Rise of the East that so dominated future visions of that era (anyone remember Crichton's hideous <em>Rising Sun</em>?) has generally failed to come to pass. Neither did World War Three. Nor did the space colonies, for that matter.<br /><br />But what makes <em>Neuromancer</em> interesting as a work of vision are the computers. Artificial intelligences and neural connections may still be the stuff of sci-fi dreams, but Gibson saw perhaps more dramatically than anyone the rise of <em>pervasive</em> computing and connectivity. While everyone else was preoccupied with hard science fiction -- precisely understanding how the things o their future would work -- Gibson ignored the details and painted with his broad noir brush strokes. As a result, he was one of the few to look far enough ahead to see what would come to pass in a few decades. Granted, there are anachronisms such as the bank of pay phones that are essential to the book's most creepy moment or the non-standard multi-pin connectors that briefly frustrate Case just shy of the climax. But overall Gibson offers no clue as to how things work (how exactly are Molly and Case able to stay in touch during the Straylight run, for example?), but just lets them happen. And as a result, he saw (in some senses quite literally) the future in a way few others ever did.<br /><br />The writing is as dark and imagistic as is the universe. The crumbling derelicts of Western Civilization are described not through sweeping panoramas but through isolated, vivid scenes. Sometimes the prose rambles on -- particularly towards the end, during the <em>2001: A Space Odyssey</em>-like descriptions of Case's final hallucinatory flight through the joint defenses of the Wintermute and Neuromancer AI's. As I said, sometimes I think Gibson really did <em>see</em> his future... <br /><br /><br /><strong>The Diamond Age</strong><br /><img src="http://lh5.ggpht.com/strauss.nick/SKV8DhfVegI/AAAAAAAAALs/_dFTg_p9tpE/eb17c060ada04410bdb79110._AA240_.L.jpg?imgmax=800" alt="eb17c060ada04410bdb79110._AA240_.L.jpg" border="0" width="240" height="240" align="left" />A stark contrast from Gibson's seat-of-the-plants imagination, <em>The Diamond Age</em> is a product of the methodical, well informed, and carefully considered work of Neal Stephenson. Here is a future cast deep into a vision of nanotechnology and digital divide. In many ways it is starkly different from Gibsons -- certainly much more of a post-Cold War work, steeped more in Huntington than in Reagan. Where <em>Neuromancer</em> presents it's future with a damn-the-details disregard for implementation and infrastructure, <em>Diamond Age</em> very nearly presents a complete course in the ideas of Alan Turing. Indeed, some of the book's most charming passages are those excerpts from the <em>Primer</em> devoted to Nell's technological education (I've actually done "<em>Primer</em> only" readings of the book -- skipping the mainline action in favor of that belonging to Princess Nell.<br /><br />It is a much more hopeful book that <em>Neuromancer</em>, even though the social and technological divide is, if anything, more dramatic than in the earlier book. Whereas <em>Neuromancer</em> presented an undeniably <strong>dark</strong> vision of humanity, <em>Diamond Age</em> somehow shows a future where, while there may be crime and corruption and war and poverty, and while the seemingly limitless power of nanotechnology has failed to fulfill more than a fraction of its promise (at least for most of the world!), the better angels of our nature still seem to have a fighting chance and the reader is left believing in heroes (and even more so in heroines, since Stephenson is just about the most feminist of science fiction authors).<br /><br />Granted, the book does occasionally suffer from logical inconsistencies, but I am willing to put this off to my incomplete understanding of the world (one could, for example, look at an incomplete narrative of events in our world and wonder why some people have amazing handled directions that instantly supply them with directions to any point on Earth...and others don't). The book (and Stephenson's work in general) has also been widely criticized for its abrupt ending. I agree -- it sometimes feels as if Stephenson felt like "alright, I'm done here, let's get this thing wrapped up" and pushed the pace in the final few dozen pages. But the fact is, the events of those pages are told with what I think is a deliberately synopsizing style. We know the characters, we know the action. In a sense, the main stories have ended. The last chapter (or two) is more like those wrap-up title cards that used to be popular in movies (and still are for docudramas) which tell the audience what characters went on to do hard time and what characters went on to found successful aerospace firms. I'm picturing the end of HBO's superlative rendition of <em>Band of Brothers</em>, by the way, where just about everyone ended up doing something amazing -- except for Dick Winters who I guess pretty much returned to farming and then quietly retired and I vaguely believe may not live too far from here. So if you view it as a wrap up, of a realization that the story is over, we're just tying off a few loose ends -- and that the story <em>isn't</em> over -- then it feels a lot better.<br /><br />I also recommend the audiobook, superbly read by Jennifer Wiltsie (incidentally that controvertial ending flows very nicely in her reading). The voice is primarily that of Princess Nell, though the characterizations are all superbly done without any of the drama or histrionic over-acting that some readers seem compelled to include.<br /><br /><br /><strong>The Name of the Rose</strong><br /><img src="http://lh4.ggpht.com/strauss.nick/SKV8KHEGP8I/AAAAAAAAALw/OzZPorq5hII/512MGT2T21L._SL500_BO2%2C204%2C203%2C200_PIsitb-dp-500-arrow%2CTopRight%2C45%2C-64_OU01_AA240_SH20_.jpg?imgmax=800" alt="512MGT2T21L._SL500_BO2,204,203,200_PIsitb-dp-500-arrow,TopRight,45,-64_OU01_AA240_SH20_.jpg" border="0" width="240" height="240" align="left" />Those of you who know me <em>knew</em> this was going to be here. It has to be, after all. It is the only medieval (I hope I spelled that right) mystery about codebreaking written by a semiotics professor I know of. It is also without a doubt the peak of Umberto Eco's willfully obtuse and esoteric writing. The very conceit of the book -- that it is a translated reconstruction of a manuscript written by a dying monk hundreds of years ago -- is pure Eco. And with his absurd range of knowledge (and feel for the styles of that age), he pulls the trick off as convincingly as Rob Reiner and Christopher Guest do in <em>This is Spinal Tap</em> (which is a great deal funnier, by the way).<br /><br /><em>The Name of the Rose</em> is a book to submit to. Before picking it up (and periodically during the reading process, whenever one of Eco's page long comma-laden sentences threatens to drive you to drink) repeat this special variation on the serenity prayer to yourself:<br /><br />Grant me the intelligence to understand the parts that can be understood.<br />Grant me the patience to make it through the parts that cannot be understood.<br />And the wonderment to enjoy it all anyway.<br /><br />(And, if necessary, go ahead and drink)<br /><br />Once you decide to take this ride, it is a little bit like a hiking trip through a strange and exotic land (right now, Erica is reading a book about someone's adventure of just this sort in China). There will be times you have no idea what is going on, but eventually frantic hand-waving will help you find the bathroom or the teahouse or the place you can buy DVD's really cheap. There will be times you are lost, confused, and worried the train that just left was the last one out for the winter. There will be times you will follow a group of people who look similar to you (and therefore must know what is going on) only to discover they are from the Ukraine and are also lost. But in the end, the trip and its memories will be an amazing collection of thoughts and experiences so rich that they have to lie in your head for months or years -- and be revisited through photographs, storytelling, and dreams -- before they form a coherent picture and their full impact is felt. <br /><br />This is how <em>The Name of the Rose</em> feels. It is a trip back to a time so different from our own that it is, in many ways, nearly incomprehensible. An Italian monastery during the time of the Papal Schism, as seen by a young boy apprenticed to a mysterious (and intentionally Sherlock-Holmes-like) monk. A mystery that explores murders that weave the most base of human desires with the most erudite. A code that, while ultimately not-so-difficult, forms one of the diverse hearts of the story. And everywhere, the complex and layered symbolism not just of Eco's own mind but that which permeated the 14th century itself. Roll with those overly-long descriptions and witch off the hyper-paced superficiality of the modern age, when beauty is just beauty and function just function. Instead get yourself thinking about the symbolism that is inherent in any object (and I take a broad definition of object, essentially using it as a postmodernist would use <em>text</em>). Today, we rarely plan symbolism, it tends to just happen as a side effect of more banal choices. Back then, it was the essential and driving design consideration.<br /><br /><br /><strong>Smiley's People</strong><br /><img src="http://lh4.ggpht.com/strauss.nick/SKV8VMMCibI/AAAAAAAAAL4/DeLtndiOYlQ/51%2BRiThlCaL._SL500_BO2%2C204%2C203%2C200_PIsitb-dp-500-arrow%2CTopRight%2C45%2C-64_OU01_AA240_SH20_.jpg?imgmax=800" alt="51+RiThlCaL._SL500_BO2,204,203,200_PIsitb-dp-500-arrow,TopRight,45,-64_OU01_AA240_SH20_.jpg" border="0" width="240" height="240" align="left" />Welcome to the 20th century. The year is, well, sometime in the late 1970's (the book was written in 1979). The cold war is at its peak, rising to a final dramatic crescendo that, though no one knows it, will suddenly flare into stillness and the end of that movement of the symphony of history. The spy game is the sweaty place of men working alone, relying on cool wit and awareness. The men who were honed in the tumult of the Second World War are now at that time in their lives when they are either pensioned retirees or string-pulling masters. John Le Carre wraps up a long and wonderful thread of two such men -- George Smiley and his Soviet foe Karla -- in a book that is, I believe, the single finest piece of spy fiction ever written.<br /><br />If you are thinking of picking it up, don't worry that you need to go back and pick up the two other books of the "main" Smiley/Karla trilogy (or the two prelude books that introduce Smiley or any of the other books in which me makes bit or major appearances). <em>Smiley's People</em> stands on its own as a single and wonderful work. I actually consider it to be significantly superior to any of the other Smiley books, to be honest. One of the joys of the book <em>is</em> the reunion value. To put it in a nutshell (I've deliberately avoided plot summaries here, but need to do a little one for this to make sense), retired and somewhat defeated British spymaster George Smiley is dragged out of his somewhat head-in-the-sand retirement for one final battle against his seemingly victorious rival from the Soviet Union (that's why I avoid plot summaries -- they always sound like that "back of the book" prose). Along the way, Smiley brings together an entire cast of characters from the old books, from the obvious (Toby Esterhase) to the obscure (Inspector Mendel). The result is a book that resonates with a "let's see what this old girl still has in her" sort of drama that I'm an admitted sucker for. It's part of what makes some of the Star Trek franchise so appealing (the Enterprise speeding away from the sabotaged Excelsior, for example, or the refitted Enterprise coming to the rescue in that glorious final episode of TNG, <em>All Good Things</em>). But you needn't actually know those stories to appreciate this aspect of the book. Indeed, I read them out of sequence since, when I picked each of them up, I had no idea the book was part of a larger whole.<br /><br />Narratively, Le Carre does one of the most masterful jobs of perspective management that I have ever seen. He shifts his focus from that of a marginally omniscient narrator to an internal monologue from a mentally troubled Russian girl with such grace that the dramatic changes in tone are entirely seamless. Some of the book has a delightful dramatic irony, where the narrator almost seems to be the author of an official Circus history looking back on the event with the perspective of months or years, breaking aside for discussions of events taking place <em>after</em> the conclusion of the mainline story and limited in knowledge by official records. At times the narrator seems to know Smiley's deepest thoughts and musings, but at times those same thoughts are protected and only accessible through observation and speculation. Throughout runs a dry and very English wit, the wry observations of a narrator as world-weary and cynically perspicacious as is his protagonist. The result is one of the most unique and entertaining narratives I have ever read. I suspect a purist would complain that it was gimmicky, inconsistent, and unprofessional. But I am not a purist and enjoy a good story, well told, by any appropriate means.<br /><br />The moments when the book does give is a look into Smiley's mind are a fantastic look into the mind of a man with (to use the book's own phrase), "many heads under his hat": retiring academic, veteran spy, civil servant, conscientious leader, failed husband, defeated warrior, and finally and most tellingly, a man who is in a position after years of frustration, failure, and inadequacy to finally gain the upper hand over his foe.<br /><br /><br /><strong>The Lord of the Rings</strong><br /><img src="http://lh5.ggpht.com/strauss.nick/SKV8wVymbFI/AAAAAAAAAMQ/mq1t7FvzWII/51ZYNQ93JZL._SL500_BO2%2C204%2C203%2C200_PIlitb-dp-500-arrow%2CTopRight%2C45%2C-64_OU01_AA240_SH20_.jpg?imgmax=800" alt="51ZYNQ93JZL._SL500_BO2,204,203,200_PIlitb-dp-500-arrow,TopRight,45,-64_OU01_AA240_SH20_.jpg" border="0" width="240" height="240" align="left" /><br />There are, in sports such as diving and gymnastics, certain obligatory moves that must be displayed during a competition or a routine. And, for some people, there are certain obligatory books that must be put on lists such as this one. <em>Lord of the Rings</em> is one of those. If I didn't include it, I'd have to hand in my Science Fiction & Fantasy Fan card and walk away in shame. But the thing is, it <em>is</em> a good inclusion. I've never been quite the fan that some become. I never tried to make my own dictionary of the Elvish language or write a fanfic (footnote: the spell checker on my blogging software, presumably the one built into OS-X 10.5, knows the word "fanfic." Tells you something, doesn't it?) or draw maps of Middle Earth. But I'm not necessarily given to such acts of devotion. <br /><br />But for richness of world, complexity of narrative, and degree of unspoken backstory, it is hard to beat Tolkien. One of the things that really does make all of his work so enjoyable is the feeling that it isn't a work of fiction, but a work of history. And just as even the most thorough of historic works can touch only a fraction of what went on (be it in a day or a few hundred years), <em>The Lord of the Rings</em> clearly touches only a fraction of what went on during those final days before the fall of Sauron. Tolkien's vast and very English scholars mind created a depth of detail that one can revel in.<br /><br />It is also the wellspring of all other "quest" books. The fellowship gathers, embarks, divides, divides again, bifurcating into multiple anfractuous plot lines. Indeed, after <em>Fellowship of the Ring</em> it is entirely possible to read LotR (I just did it, I used the fanboy shorthand, sorry) as several concurrent novels, picking and choosing story lines. "Hm...today I think I will read just the story of Pippen..." But, gloriously, everything comes together at the end as, through nearly independent action (or the smooth hand of fate) the principles come back together, one at a time, until the final tearful reunion.<br /><br />The dialogue may, at times, be heavy handed. I find Tolien's insistence on those interminable songs profoundly irritating (granted, he's trying to build a viking-like character, but this didn't need to turn so Wagnerian!). Sometimes the exclusion of backstory can leave the new reader staggering along for a few dozen or a few hundred pages (but you always know that exclusion is deliberate and not the product of the author not <em>knowing</em> what happened outside the story). The number of named characters defies counting, and little guidance is initially provided as to the potential importance of a newcomer. <br /><br />But for all that, for all of the flaws it <em>does</em> possess, the work is a true epic. Sweeping, grand, and beautiful in scope.<br /><br /><br /><strong>The Codebreakers</strong><br /><img src="http://lh5.ggpht.com/strauss.nick/SKV8fEaLM9I/AAAAAAAAAMA/04oIdi-bf1c/51EJ2XMYMEL._SL500_AA240_.jpg?imgmax=800" alt="51EJ2XMYMEL._SL500_AA240_.jpg" border="0" width="240" height="240" align="left" /><br />Somewhat tongue-in-cheekishly, I credit this book with my marriage to Erica. To give it full credit is obviously absurd, my willingness to eat the deep fried shrimp heads clearly counted for something. But despite later culinary adventures, our shared ownership of this book was one of the first "hey, this guy/gal looks interesting!" moments. At least we knew we'd have <em>one</em> thing to talk about on a date.<br /><br />Simply put, <em>The Codebreakers</em>is a seminal work that has yet to be even remotely equaled. It is, without a doubt, the best single volume telling of the history of code-making and code-breaking up through the first third of the 20th century. Later than that and it starts to run into the constraints of secrecy -- the Enigma decrypts of the Second World War weren't made public until several years after its first publication -- and of a slapdash effort by Kahn to update the text with such modern technologies as the DES standard. But he is out of his element here, and that's why <em>Applied Cryptography</em> is on the list in any case. For the eras when ciphers were produced by men laboring with pencils, paper, typewriters, and perhaps primitive collections of wheels and rods (he does a decent job with technology up to about the Hagelin machines), for the era when the field was more intuition and art than the rigorous solving of equations that XXXX turned it into, this is simply <em>the</em> text. <br /><br />As many historians do, Kahn does sometimes write for his time, implying that the reader should have familiarity with events and people now rendered obscure by the three and a half decades since the text was produced. There is also a definite conservatism in the work, something that the eccentric nature of those drawn to cryptography inescapably draws out. But for telling the human tale of an intensely technical field, Khan's book is without equal (just ignore the moments when his reporting turns to judging). To hear how Georges Painvin broke ADGVX through a single immense act of will, loosing a dozen or more pounds in the process, <em>The Codebreakers</em> is the book. To hear about eccentric Victorian gentlemen-scholars inventing cipher systems between dabbling in natural philosophy and at attending hunts, it is the book.<br /><br /><br /><strong>A Distant Mirror</strong><br /><img src="http://lh3.ggpht.com/strauss.nick/SKV8sHcpvqI/AAAAAAAAAMM/Q3ATCzD0zQ4/51i-FeNgY5L._SL500_BO2%2C204%2C203%2C200_PIsitb-dp-500-arrow%2CTopRight%2C45%2C-64_OU01_AA240_SH20_.jpg?imgmax=800" alt="51i-FeNgY5L._SL500_BO2,204,203,200_PIsitb-dp-500-arrow,TopRight,45,-64_OU01_AA240_SH20_.jpg" border="0" width="240" height="240" align="left" />You're probably starting to realize how much I enjoy history. I read, at least partially, for a sense of escape. I want to get away from my corporate day job where people feel the need to invent replacements for perfectly good words (e.g. saying "we'll go ahead of the ask succeeds and we get funding" rather than the perfectly good and well seasoned word <em>request</em>). But I digress. No world is more bizarre and alien than the 14th century. And given that I just pushed through a few science fiction novels, that is saying something!<br /><br />In all seriousness, Tuchtman writes a great history here. It is a history of a time so distant in time and values that it really does feel, at some times, <em>alien</em>. She brilliantly structures the work around the armature of a single man's life, using this structure to organize the background and the primary narrative. Instead of <em>only</em> giving us the distant, dispassionate perspective of typical histories, she illustrated the sweep of the times through what is essentially a massive and recursive work of biography, always sweeping aside to cover a tangent and then flying back to the main story, grounding the dramatic events of that age in the life of a single blading man. <br /><br />And what a collection of events the 14th century provides us with. I've already talked about <em>A Distant Mirror</em> in regards to its totemistic value as a perspective provider ("It can't be that bad...") whenever the nightly news gets a little depressing. And it was indeed a motivation similar to this that inspired Ms. Tuchtman to write the book. But here, in one book, we have the papal schism, the black death, and the hundred years war. It is enough tumult to satisfy a millennium's worth of tragedy, all packed into a hundred years. Given the drama (and most of it bad) contained in this history, it could easily turn maudlin and depressing. But the pervasive perspective is the ability of humanity to adapt and survive. It is, as such, a profoundly motivating and reassuring book, in addition to being densely informative.<br /><br /><br /><strong>The Fabric of the Cosmos</strong><br /><img src="http://lh3.ggpht.com/strauss.nick/SKV8p24-XeI/AAAAAAAAAMI/3VC9H3SnZo4/510ED66FD8L._SL500_AA240_.jpg?imgmax=800" alt="510ED66FD8L._SL500_AA240_.jpg" border="0" width="240" height="240" align="left" />One day, before I die, I would like to understand <em>everything</em> in this book. I suspect that, when that happens, I will quietly dissolve into a vaporous cloud of disassociating particles. Fortunately, it will take quite a long time for that to occur.<br /><br />Brian Greene, everyone's favorite vegetarian string theorist, tackles not his particular specialty (and despite Roger Penrose's characterization of him as a hedgehog, Greene certainly knows enough of a breadth of physics to pull this off) but rather the entire scope and wonder of the leading edge of physical understanding. Several ingredients contribute to ming <em>Fabric of the Cosmos</em> so wonderful to read. Greene's brilliant analogies (usually involving The Simpsons) not only clarify concepts but are amusing in their own right (the whole book has a dry and subtle wit). The physics discussed is profoundly interesting, even disturbing if you don't accept the idea that our reality may well be quite a bit more subtle and bizarre than generally expected. But finally, and perhaps most significantly, is Greene's own fascination with the material he is coming. The book brims with his own energy and enthusiasm, sense of wonder and amazement. In many ways, despite the enormity of the material covered, the book is very personal, opening as it does with an anecdote from the author's childhood and moving on to discuss the very researches that fill his day job (and what a day job) at Columbia University. This comes through most clearly in the final chapters when Greene quite admittedly takes the current state of the known and speculative art and plunges headlong into the visionary realms of where this knowledge could take us. <br /><br />The entire book is set as a wide-ranging tour, a grand sweep across the most fundamental infrastructure of the universe. The big bang, inflation, the kinky activities inside the Planck limit, the quantum and the Einsteinean, all get some time. Unlike <em>The Elegant Universe</em>, Greene's first book, this is not an evangelism of String Theory. Obviously this approach to answering the fundamental questions and contradictions that currently arise in physics figures prominently, being Greene's area of research and specialization. But the book only graces this area when appropriate and necessary. I actually wish that it spent more time here -- I truly <em>like</em> the ideas of String Theory (as much as it might currently be caught in a physical backlash), but can always pick up the adjacent and equally well thumbed copy of <em>Elegant Universe</em> when I need to.<br /><br /><br /><strong>On Food and Cooking</strong><br /><img src="http://lh4.ggpht.com/strauss.nick/SKV8ZF3aNLI/AAAAAAAAAL8/KFpo5PUs3HY/51K2FNA72QL._SL500_BO2%2C204%2C203%2C200_PIsitb-dp-500-arrow%2CTopRight%2C45%2C-64_OU01_AA240_SH20_.jpg?imgmax=800" alt="51K2FNA72QL._SL500_BO2,204,203,200_PIsitb-dp-500-arrow,TopRight,45,-64_OU01_AA240_SH20_.jpg" border="0" width="240" height="240" align="left" />What could be better than a book that is simultaneously about science <em>and</em> cooking? Very few things, I tell you that, when the book has the lucid explanations, beautiful production, and sweeping scope of <em>On Food and Cooking</em>. As an aside, you many have noticed just how often the word <em>sweeping</em> shows up as a word of praise in this entry (at least I think it does!). I tend to like my non-fiction that way: broad, epic, profound. I'm a generalist, I suspect, and like situations that let me see as broad a scope as possible. I also relish the moment of connection when seemingly disparate threads merge into a single coherent story.<br /><br />Part of the appeal of <em>On Food and Cooking</em> is its fearless willingness to actually tackle some organic chemistry. I've often characterized this branch of the sciences as the one that I simply don't get. And it is true. Those who understand it tell me its easy, I just need to memorize few things. I think they possess some strange gift. Organic chem (or "Orgo") isn't like, say, the way-out-there physics of <em>The Fabric of the Cosmos</em>. That's like reading a complicated story that is in a language you know. Organic chemistry is like reading a complicated story in a language you've never seen before. For me at least! McGee manages to tackle the fundamentals of orgo pretty clearly -- probably partially because he has a clearly defined upper bound of complexity and partially because the topic he's working with (food) is more motivating than that of most organic chemistry texts. The explanations are also lucid and engaging, trust me, so it is not entirely the appeal of the topic that is at hand.<br /><br />But beyond the orgo, this is a book about food, abut how food happens, about what food does, and about why all of these things happen. The popularization of food science owes a lot to Alton Brown, The Food Network's geek-cook extraordinaire (though I will say that I've liked Alton's shows less and less -- as he seems to rebrand from a geek into more of a welding-glove-wearing-man's-man-chef character). Now it doesn't take much exploration to realize that Alton learned everything he knows about food science from periodic guest Shirley Corriher and her fantastic book <a href="http://www.amazon.com/Cookwise-Secrets-Revealed-Shirley-Corriher/dp/0688102298">CookWise</a>. This book is, in its own turn, a more conversational and applied version of <em>On Food and Cooking</em>. I've obviously chosen to go straight to the most pure source I know, skipping the intermediates.<br /><br /><em>On Food and Cooking</em> is as endlessly interesting (and entertaining) as is the world's unending variety of food.<br /><br /><br /><strong>Applied Cryptography</strong><br /><img src="http://lh6.ggpht.com/strauss.nick/SKV8ivO6RoI/AAAAAAAAAME/1aXYCLFU6Z0/417CCGH2GKL._SL500_BO2%2C204%2C203%2C200_PIsitb-dp-500-arrow%2CTopRight%2C45%2C-64_OU01_AA240_SH20_.jpg?imgmax=800" alt="417CCGH2GKL._SL500_BO2,204,203,200_PIsitb-dp-500-arrow,TopRight,45,-64_OU01_AA240_SH20_.jpg" border="0" width="240" height="240" align="left" /><br />I keep trying to replace <em>Applied Cryptography</em> in my collection. It is, after all, more than a decade old in a field that has seen shockingly rapid advancement in that time. Most of the algorithms discussed in the book are obsolescent in today's security world. Perhaps even more critically, an awareness of system design now permeates security thinking, and not just a building-block approach. But nothing, and I mean <em>nothing</em> that has come out since 2001 has offered more than the slimmest threat to Schnier's classic. <em>Practical Cryptography</em> comes close, really close. And, if a second edition were to come out that updated <em>it</em> to include the latest and greatest, it would stand a real shot at taking the crown of Modern Cryptography Book On Nick's Island.<br /><br />But enough about its superficial obsolescence, what has <em>Applied Cryptography</em> done so well that it still shows up on the list? The answer is that, like no other book on the topic, it builds an actual understanding of how the processes of security work. It contains <em>both</em> the mathematical rigor required to construct (or deconstruct) a security system and even more profoundly an ability to explain...to <em>clarify</em>...how these mathematical components operate. It takes the time to step, conceptually, through the now iconic cases of Alice, Bob, Mallory, and the various other characters of Schnier's explanations. It backs these cases up with some of the underlying constructs and mathematics. The recently maligned weak point is that the focus is on explaining individual systems and not on overall processes -- but as someone who does not intend to actually design a cryotpsystem, the clarity of these explanations makes their omissions entirely forgivable.<br /><br />Much of the content, then, is timeless. Most of the great message passing schemes remain unchanged, or at least still valid. The ciphers discussed may not be fighting in the front lines anymore, but that does not make them unworthy of study. The knowledge in this book has not been replaced, merely supplemented. Now if I were heading off to a desert island, I'd like to take my copy with me just as it is -- broken spine and all -- for the sake of the half dozen printouts I've stuck in between various pages, updating the content with some current state-of-the-art examples of cipher algorithm design. Let me stick in a few sheets of paper and, no reservations at all, <em>Applied Cryptography</em> will beat all comers, hands down and no reservations: Rijndael/AES, of course, the flawed but endemic mobile communications ciphers of A5/1, E0, and KASUMI, the fascinating but flawed Roo/Py and Phelix, the phenomenal elegance of Trivium and Grain, and the enigmatic Don Coppersmith's suspiciously rotor-like Scream. That's nine ciphers...might as well make it ten and throw in Camellia for a look at Japan's stylings in the area.<br /><br />But this is the sort of book that <em>should</em> have a busted spine, dog-eared pages, notes and highlights, and random pieces of paper sticking out of it. In the way that comic book readers show their love in a carefully bagged-and-boarded book, readers of <em>Applied Cryptography</em> should show their love love in a manner more akin to that scene in the sauce stained, water wrinkled, footnoted pages of cook books.<br /><br /><br />Just Nickhttp://www.blogger.com/profile/01845987547854457407noreply@blogger.com0tag:blogger.com,1999:blog-5333608194352082143.post-57378472954612228632008-08-18T18:15:00.001-07:002008-08-18T20:09:31.947-07:00The Reunion BookSo something interesting arrived in today's mail. It was sitting at the door (so it may actually have arrived by UPS, I don't know, I didn't pay attention) in a big fat fluffy envelope. The kind with the irritating tendency to emit small clouds of a substance that appears visually and texturally similar to blow-in insulation. As, in fact, this one did.<br /><br /><img src="http://lh5.ggpht.com/strauss.nick/SKoaR_wvpnI/AAAAAAAAAMU/mdNGvGAJeBE/images.jpeg?imgmax=800" alt="images.jpeg" border="0" width="146" height="146" align="left" />It was stickered as coming from the Stanford Alumni association and turned out to contain an interesting object called a "Reunion Book." I'd never heard of one of these before, so I assume that some of you are as ignorant as I was. It is a sort of reverse-yearbook, a "where are we now" of all the people you entered college with. Or graduated with. Or should have graduated with. I haven't really explored the details. <br /><br />Everyone got a little one page spread of a then-and-now photo pair, a brief bio, a personal timeline, and a photo of their choosing. It turns out that if I'd done the conventional thing I would have graduated from college fifteen years ago. Wowsers. So I couple of interesting things: I'm not in it. I feel vaguely resentful that the alumni association apparently was able to track me down to get me a copy of the book but didn't get in touch with me in time to fill out my form or whatever was required to get my own page. Now, in all honesty, this omission was probably my fault. I tend to regard mail from the alumni association with a sort of irritated inevitability. I tend not to open it. I assume, based on my sample of the times I actually <em>do</em> open and read mail from them, that they want me to subscribe to something or donate something or attend an event.<br /><br />It may shock those of you with a great deal of college pride that could do something so profoundly heretical. But the reality is that I regard college as sort of "a place I was for a while." This wasn't some sort of chemically induced stupor at work. I didn't discover alcohol until a few years into my education and even then played fairly lightly. And I never decided to pursue studies in Advanced Controlled Substances or anything.<br /><br />College just wasn't the earthshaking, life changing event, for me, that it was for some others. No comment or criticism on either perspective, by the way. I actually wish I'd gotten a little more out of Stanford academically than I did. I pretty much treated the place as a big, hard high-school. I took my classes, did my work, and called it at that. By contrast, it amazes me how much Erica got out of her studies, capturing absolutely everything that school could provide. And sometimes I wonder what I could have gotten out of the Stanford experience if I'd had the realization (a) what an amazing place it was and (b) college <em>isn't</em> just a big, hard high school.<br /><br />I also didn't graduate on time, but took a winding and indecisively exploratory path from start to finish. So I ended up loosing track with a lot of those freshman year friends that everyone tells you you'll never forget. I made new friends on the way, but by that time was living off campus and separated by a few crucial years (at that age) from most of those I was in classes with. Then, after spending too long there, I bolted for the Pacific Northwest and an all consuming few years at Amazon. I really only took two good friends from those days with me -- and neither of them from the freshman gaggle. It occurs to me, now that I think about it, that I might have dropped off the radar. And I suppose that'd be a fair thing to say.<br /><br />I've tracked a few folks down from high school and Amazon via my Facebook presence, but had little luck with people from the college years. To at least some extent it was too large of a pool, and too long ago, to bring up any names. I knew I was missing something of this opportunity to reconnect, but could think of no way to drag all those names back from the dust laden vaults.<br /><br />And then this giant book arrives, full of (almost) everyone from my freshman year. Now granted, all of those transitory friends from later aren't covered -- but this is at least a break in the case! I've just flipped through it a little and have yet to embark on some great quest, going page-by-page and launching Facebook/Internet searches for everyone who looks or sounds familiar. But here are a few interesting observations.<br /><br />None of the people I looked at have gotten divorced -- in many cases they are still married to people they were dating when I knew them.<br /><br />At least one person from my freshman class included a photo posing between Barack Obama and Oprah. I do not, however, think she was someone I knew.<br /><br />Most of the people I looked at have families (kids) now. The rest have pets.<br /><br />Almost everyone I looked at listed "hiking" or something similar as an interest.<br /><br />Based on the photos, if I met most of them, now, I'd probably do a better job recognizing them that I would have expected.<br /><br />How did we ever think the hair styles of that era looked good? Particularly the women's hair...<br /><br />I really want to track some folks down and say hi...<br /><br />Memories can come back when given a proper trigger.<br /><br />Everyone seems to be doing well -- practicing in whatever profession or field I recall them as interested in when the left, and practicing successfully and at a fairly (or very) high level.<br /><br />By and large, I found the lives to be pleasantly (and to some extent surprisingly) similar to my own. I'm not quite sure what I expected, but I think I harbored this belief that everyone I'd gone to school with had gone on to found startups, cure diseases, found countries, or win Nobel Prizes or Oscars or Olympic medals or Booker Book prizes. I think it is a continuing thread of insecurity I suffer whenever I look at some of the people I worked with at Amazon -- the ones who really got the bug and leveraged that experience and those contacts to remain (and climb) in the aggressive startup-founding-mandhouse of entrepreneurship. Whenever that hits me I have to remind myself <em>that's not me</em>. I'm a guy who works because he has to -- to provide for himself and his family and to enable the things that we really want to do. I don't fight the fight because I love the fight. I do what I have to -- and I'm fortunate enough to enjoy what I do and be good at it and to have the opportunity to work very hard and be well rewarded. And then I look at (and think of) those one-time co-workers of mine who went down the other path, my path, and raised families, went to school, traveled, and worked when they had to. Again, no judgement. Thank god for the compulsive entrepreneur. They are there to build companies, take risks, hang it on the line day after day. The world would be a very dull place without them.<br /><br />But yet again, dear Reunion Book, I am pleased to see the world populated with (extremely) intelligent, hard working people who are out there doing what they do. And, I hope, loving what they do and finding themselves well rewarded for it. And, I hope, finding the time to go hiking or traveling or back to school or to write books or to make par at Pebble Beach or to chase down all of the extraordinary and wonderful dreams and goals that people should have. If you found a few companies, cure a disease, or win a couple of prizes on the way, then more power to you! But if you're working the day job, doing something fun on the side, and coming home to share nap time with your kids, congratulations just the same.<br /><br />I'm a guy who loves nothing more than to come home and sit on the back patio with a glass of whisky, a laptop computer, and a cool breeze blowing by. And that's just exactly what I'm doing. Now I just need to start going page by page and searching Google and Facebook for everyone who looks or sounds familiar... See you soon, I've missed you more than I realized.<br /><br />If you got here first (I can't be the only person with the "I'll Google people!" brainstorm), then leave a comment or drop me a line (strauss.nick@gmail.com).Just Nickhttp://www.blogger.com/profile/01845987547854457407noreply@blogger.com0
