Communion Of Dreams


Gun geekin’.

OK, this post is about guns. In particular the M1911 .45. You’ve been warned.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Recently a friend passed along this quote:

“A society of sheep must in time beget a government of wolves.”
Bertrand de Jouvenal

I’ve frequently talked about guns, and several times explicitly mentioned that my basically liberal/libertarian political philosophy is completely comfortable with understanding the 2nd Amendment of the US Constitution as being an individual right. Part of this is in realizing that the world is a dangerous place and that you have to make reasonable preparations to take care of yourself. And part of it is understanding that one check on the abuse of governmental power is a population which is armed and prepared to defend its civil liberties.

No, I have no illusions that I, with a few pistols and shotguns (or my flintlock), am any kind of a challenge to a modern police force, let alone an actual army. And that is the way it should be – no individual should be outside the law. But collectively, a populace armed with tens of millions of such weapons presents a real check on tyranny. The calculus of trying to use military-level force against the population of the US would have to take this into account; either overwhelming mass destruction (and I’m not saying it would have to include WMDs) would have to be employed, or such a military force would have to be willing to suffer significant casualties. This is a substantial disincentive to anyone who might be willing to attempt such a thing.

Not that I can’t imagine possible scenarios where this may come to pass. In fact, one such is part of the ‘history’ of Communion of Dreams, following the initial Fire Flu of the backstory. I may get around to writing some of that one of these days, though there is already a fair amount of literature with that setting available.

Anyway, this rumination was prompted by my friend’s quote, and on a nice post that I came across on MeFi that linked to a cool animation of assembling an M1911 .45:

If you would like to see an even better animation of how a 1911 functions, which allows you to hide or show various components as it operates, then go check out this site. I had shot a fairly standard 1911 a good deal when I was young, but was never particularly enamored of that style of gun, preferring more ‘modern’ semi-auto pistols. Until I was gifted with a very nice one from a friend’s collection early this year – a modification on the standard design which provides for the additional safety of a double-action trigger. It is perhaps the sweetest-shooting pistol I have, even while being one of the most powerful ones. There is a lot to be said for the venerable design of the 1911, a gun said to be designed by a genius for use by morons, with ballistic performance suitable for service in four wars . Works for me.

Well, as I’ve said before, I know a lot of people don’t want a gun in their home. Fine, don’t have one. But if you are going to have one, learn to use it and store it safely. And if you’re going to have one, you certainly could do a lot worse than have a 1911 model .45 of some variation.

Oh! Lookit the purty pictures!

Do you like APOD? Dig great shots of space? Love to poke around the various and sundry sites where NASA has images?

Then boy, are you in luck:

NASA AND INTERNET ARCHIVE LAUNCH CENTRALIZED RESOURCE FOR IMAGES

WASHINGTON — NASA and Internet Archive, a non-profit digital library based in San Francisco, made available the most comprehensive compilation ever of NASA’s vast collection of photographs, historic film and video Thursday. Located at www.nasaimages.org, the Internet site combines for the first time 21 major NASA imagery collections into a single, searchable online resource. A link to the Web site will appear on the www.nasa.gov home page.

The Web site launch is the first step in a five-year partnership that will add millions of images and thousands of hours of video and audio content, with enhanced search and viewing capabilities, and new user features on a continuing basis. Over time, integration of www.nasaimages.org with www.nasa.gov will become more seamless and comprehensive.

“This partnership with Internet Archive enables NASA to provide the American public with access to its vast collection of imagery from one searchable source, unlocking a new treasure trove of discoveries for students, historians, enthusiasts and researchers,” said NASA Deputy Administrator Shana Dale. “This new resource also will enable the agency to digitize and preserve historical content now not available on the Internet for future generations.”

How many images are we talking about? Over 100,000 at present. Completely searchable. The homepage is broken down into several categories (Universe, Solar System, Earth, Astronauts) and contains an interactive timeline of the space program going back 50 years. Each search generates a page of thumbnail images – Titan calls up almost 1,500 – leading to photos, animations, audio files, and artist’s renderings.

Wow. Just wow.

Damn, and I have work I need to get done this afternoon . . .

“Doom, DOOM, I say!!”

A good friend sent me a link to a longish piece in the latest edition of The Atlantic titled Is Google Making Us Stupid? by author Nicholas Carr. It’s interesting, and touches on several of the things I explore as future technologies in Communion of Dreams, and I would urge you to go read the whole thing.

Read it, but don’t believe it for a moment.

OK, Carr starts out with the basic premise that the human mind is a remarkably plastic organ, and is capable of reordering itself to a large degree even well into adulthood. Fine. Obvious. Anyone who has learned a new language, or mastered a new computer game, or acquired any other skill as an adult knows this, and knows how it expands one’s awareness of different and previously unperceived aspects of reality. That, actually, is one of the basic premises behind what I do with Communion, in opening up the human understanding of what the reality of the universe actually is (and how that is in contrast with our prejudices of what it is).

From this premise, Carr speculates that the increasing penetration of the internet into our intellectual lives is changing how we think. I cannot disagree, and have said as much in several of my posts here. For about 2/3 of the article he is discussing how the hyperlinked reality of the web tends to scatter our attention, making it more difficult for us to concentrate and think (or read) ‘deeply’. Anyone who has spent a lot of time reading online knows this phenomenon – pick up an old-fashioned paper book, and you’ll likely find yourself now and again wanting explanatory hyperlinks on this point or that for further clarification. This, admittedly, makes it more difficult to concentrate and immerse yourself into the text at hand, to lose yourself in either the author’s argument or the world they are creating.

But then Carr hits his main point, having established his premises. And it is this: that somehow this scattered attention turns us into information zombies, spoon-fed by the incipient AI of the Google search engine.

Huh?

No, seriously, that’s what he says. Going back to the time-motion efficiency studies pioneered by Frederick Winslow Taylor at the turn of the last century, which turned factory workers into ideal components for working with machines, he makes this argument:

Taylor’s system is still very much with us; it remains the ethic of industrial manufacturing. And now, thanks to the growing power that computer engineers and software coders wield over our intellectual lives, Taylor’s ethic is beginning to govern the realm of the mind as well. The Internet is a machine designed for the efficient and automated collection, transmission, and manipulation of information, and its legions of programmers are intent on finding the “one best method”—the perfect algorithm—to carry out every mental movement of what we’ve come to describe as “knowledge work.”

Google’s headquarters, in Mountain View, California—the Googleplex—is the Internet’s high church, and the religion practiced inside its walls is Taylorism. Google, says its chief executive, Eric Schmidt, is “a company that’s founded around the science of measurement,” and it is striving to “systematize everything” it does. Drawing on the terabytes of behavioral data it collects through its search engine and other sites, it carries out thousands of experiments a day, according to the Harvard Business Review, and it uses the results to refine the algorithms that increasingly control how people find information and extract meaning from it. What Taylor did for the work of the hand, Google is doing for the work of the mind.

The company has declared that its mission is “to organize the world’s information and make it universally accessible and useful.” It seeks to develop “the perfect search engine,” which it defines as something that “understands exactly what you mean and gives you back exactly what you want.” In Google’s view, information is a kind of commodity, a utilitarian resource that can be mined and processed with industrial efficiency. The more pieces of information we can “access” and the faster we can extract their gist, the more productive we become as thinkers.

Where does it end? Sergey Brin and Larry Page, the gifted young men who founded Google while pursuing doctoral degrees in computer science at Stanford, speak frequently of their desire to turn their search engine into an artificial intelligence, a HAL-like machine that might be connected directly to our brains. “The ultimate search engine is something as smart as people—or smarter,” Page said in a speech a few years back. “For us, working on search is a way to work on artificial intelligence.” In a 2004 interview with Newsweek, Brin said, “Certainly if you had all the world’s information directly attached to your brain, or an artificial brain that was smarter than your brain, you’d be better off.” Last year, Page told a convention of scientists that Google is “really trying to build artificial intelligence and to do it on a large scale.”

Such an ambition is a natural one, even an admirable one, for a pair of math whizzes with vast quantities of cash at their disposal and a small army of computer scientists in their employ. A fundamentally scientific enterprise, Google is motivated by a desire to use technology, in Eric Schmidt’s words, “to solve problems that have never been solved before,” and artificial intelligence is the hardest problem out there. Why wouldn’t Brin and Page want to be the ones to crack it?

Still, their easy assumption that we’d all “be better off” if our brains were supplemented, or even replaced, by an artificial intelligence is unsettling. It suggests a belief that intelligence is the output of a mechanical process, a series of discrete steps that can be isolated, measured, and optimized. In Google’s world, the world we enter when we go online, there’s little place for the fuzziness of contemplation. Ambiguity is not an opening for insight but a bug to be fixed. The human brain is just an outdated computer that needs a faster processor and a bigger hard drive.

Do you see the pivot there? He’s just spent over a score of paragraphs explaining how the internet has degraded our ability to concentrate because of hyperlinked distractions, but then he turns around and says that Google’s increasing sophistication at seeking out information will limit our curiosity about that information.

No. If anything, the ability to access a broader selection of possible references quickly, the ability to see a wider scope of data, will allow us to better use our human ability to understand patterns intuitively, and to delve down into the data pile to extract supporting or contradicting information. This will *feed* our curiosity, not limit it. More information will be hyperlinked – more jumps hither and yon for our minds to explore.

The mistake Carr has made is to use the wrong model for his analogy. He has tried to equate the knowledge economy with the industrial economy. Sure, there are forces at play which push us in the direction he sees – any business is going to want its workers to concentrate on the task at hand, and be efficient about it. That’s what the industrial revolution was all about, from a sociological point of view. This is why some employers will limit ‘surfing’ time, and push their workers to focus on managing a database, keeping accounts balanced, and monitoring production quality. While they are at work. But that has little or nothing to do with what people do on their own time, and how the use the tools created by information technology which allow for much greater exploration and curiosity. And for those employees who are not just an extension of some automated process, those who write, or teach, or research – these tools are a godsend.

In fairness, Carr recognizes the weakness in his argument. He acknowledges that previous technological innovations on a par with the internet (first writing itself, then the development of the printing press) were initially met with gloom on the part of those who thought that it would allow for the human mind to become lazy by not needing to hold all the information needed within the brain itself. These predictions of doom proved wrong, of course, because while some discipline in holding facts in the brain was lost, increasing freedom with accessing information needed only fleetingly was a great boon, allowing people to turn their intellectual abilities to using those facts rather than just remembering them.

Carr ends his essay with this:

I’m haunted by that scene in 2001. What makes it so poignant, and so weird, is the computer’s emotional response to the disassembly of its mind: its despair as one circuit after another goes dark, its childlike pleading with the astronaut—“I can feel it. I can feel it. I’m afraid”—and its final reversion to what can only be called a state of innocence. HAL’s outpouring of feeling contrasts with the emotionlessness that characterizes the human figures in the film, who go about their business with an almost robotic efficiency. Their thoughts and actions feel scripted, as if they’re following the steps of an algorithm. In the world of 2001, people have become so machinelike that the most human character turns out to be a machine. That’s the essence of Kubrick’s dark prophecy: as we come to rely on computers to mediate our understanding of the world, it is our own intelligence that flattens into artificial intelligence.

Wrong. Wrong, wrong, wrong. This is a complete misreading of what happens in the movie. Kubrick’s vision was exactly the opposite – HAL was quite literally just following orders. Those orders were to preserve the secret nature of the mission, at the expense of the lives of the crew whom he murders or attempts to murder. That is the danger in allowing machinelike behaviour to be determinant. Kubrick (and Arthur C. Clarke) were, rather, showing that it is the human ability to assess unforeseen situations and synthesize information to draw a new conclusion (and act on it) which is our real strength.

*Sigh*

“…we were not alone…”

I mentioned in passing last week that I was working on all my care-giving posts for a book. Here’s a bit more about that project, as it is tentatively shaping up.

Sometime last year, when I cross-posted one of those entries on Daily Kos, I discovered that there was someone else there who was in pretty much the exact same situation: caring for a beloved mother-in-law. For a variety of reasons, it is fairly unusual to find a man caring for a mother-in-law with dementia. We didn’t strike up what I would call a friendship, since both of us were preoccupied with the tasks at hand, but we did develop something of a kinship, commenting back and forth in one another’s diaries on that site. Our paths diverged – he and his wife eventually needed to get his mother-in-law into a care facility, whereas my wife and I were able to keep Martha Sr home until the end. But the parallels were made all the more striking by those slight differences. In the end, his “Mumsie” passed away about six weeks before Martha Sr died.

Recently this fellow and I picked up the thread of our occasional conversation once again. And discovered that both of us, independently, had been thinking of writing up a book about the experience of care giving. It didn’t take long before we realized that together we could produce a more comprehensive book, and a lot more easily, drawing on our individual experiences to show similarities and different choices. A few quick emails sorted out the pertinent details – basic structure of the book, that all proceeds from it will go to the Alzheimer’s Association (or them and other related organizations), some thoughts on publishing and promotion – and we were off and running.

For now, I’ll just identify him by his screen name: GreyHawk. By way of introduction, check out this excellent post of his at ePluribus Media, where he very neatly explains the *why* of our decision to write this book:

Special thanks to Jim Downey for the supplying the links to the video and to his blog, and just for being him; my wife and I took comfort from the fact that we were not alone in our situation, and that we knew at least one other couple who were going through a very similar experience to our own.

That’s it right there. Millions of Americans are facing this situation today, and millions more will in coming years as the baby-boomer generation ages. I’m not a scientist who can help find a cure to the diseases of age-related dementia. I’m not wealthy and able to make a significant difference in funding such research. But I can perhaps help others to understand the experience. GreyHawk and I are going to try, anyway. I know that my wife and I found comfort in knowing that we were not alone in this. So did he and his wife. If we can share that with others, and make their experience a little more understandable, a little easier, then that will be a worthy thing.

Wish us luck.

Where were you?

Do you recognize these words?

“HOUSTON, TRANQUILITY BASE HERE.
THE EAGLE HAS LANDED.”

Of course you do. That’s the transmission sent to NASA Mission Control from the Moon on this date in 1969.

I was at a Boy Scout camp outside of St. Louis when it happened. That night, we all sat around a big firepit, and tried to watch a small black and white portable television with bad reception as Neil A. Armstrong and Edwin (Buzz) E. Aldrin, Jr. made the first human steps onto the Lunar surface and spoke these words (links to audio file on Wikipedia):

“That’s one small step for (a) man, one giant leap for mankind.”

And the world was changed forever.

So, where were you?

Wasn’t that a plot point . . . ?

I just came across an interesting idea from Michael Benson in the Washington Post last weekend:

Send It Somewhere Special

Consider the International Space Station, that marvel of incremental engineering. It has close to 15,000 cubic feet of livable space; 10 modules, or living and working areas; a Canadian robot arm that can repair the station from outside; and the capacity to keep five astronauts (including the occasional wealthy rubbernecking space tourist) in good health for long periods. It has gleaming, underused laboratories; its bathroom is fully repaired; and its exercycle is ready for vigorous mandatory workouts.

The only problem with this $156 billion manifestation of human genius — a project as large as a football field that has been called the single most expensive thing ever built — is that it’s still going nowhere at a very high rate of speed. And as a scientific research platform, it still has virtually no purpose and is accomplishing nothing.

* * *

Send the ISS somewhere.

The ISS, you see, is already an interplanetary spacecraft — at least potentially. It’s missing a drive system and a steerage module, but those are technicalities. Although it’s ungainly in appearance, it’s designed to be boosted periodically to a higher altitude by a shuttle, a Russian Soyuz or one of the upcoming new Constellation program Orion spacecraft. It could fairly easily be retrofitted for operations beyond low-Earth orbit. In principle, we could fly it almost anywhere within the inner solar system — to any place where it could still receive enough solar power to keep all its systems running.

Like I said, interesting. But problematic – the ISS wasn’t constructed to provide adequate protection from radiation (the orbit it occupies is within the Earth’s protective magnetosphere), and therefore would need to be retrofitted extensively to protect inhabitants on a long-distance voyage. It would likely also need retrofitting to reinforce the many joints where components have been mounted together, since these were not designed to withstand significant stress from propulsion.  I think Mr. Benson may have underestimated these problems and costs.

But it is still an interesting idea.  Unfortunately, it’s not original.  Well, not exactly.  Like so many things related to our early exploration in space, something similar was proposed by Arthur C. Clarke over 25 years ago.  Yes, about 15 before construction began on the ISS.   It is a plot point in his novel 2010: Odyssey Two (the book differs significantly from the movie 2010, so you may not have come across it).  In the book, a Chinese space station under construction in LEO surprisingly reveals itself to be an interplanetary craft, and takes off for Jupiter, getting the jump on both the American and Soviet missions planned to investigate the monolith in orbit there.

Just a little factoid for a Sunday morning.

9.35% Return.

Last Friday we crossed 10,000 downloads of Communion of Dreams.  By Monday we had another 500 downloads.   By this morning it was another 435.  That’s 935 downloads in a week.  Or, put it another way, that’s a 9.35% increase.  Sorta like a return on investment.  Let’s see . . . a simple interest calculation . . . 10,000 (base) x 0.0935 (% increase) x 52 (weeks per year) . . . in one year, another 48,620 people will have downloaded Communion at this rate.  Of course, if we *compound* the increase (saying that we’ll not have 935 downloads each week, but rather a 9.35% increase each week) then that results in over a million downloads (check it yourself).

Woo-hoo!  Time to get a publisher – who wouldn’t want a million-seller book?

Big-time, here I come!

More tears.

(This post has been expanded and rewritten.)

Been a long week.  I mentioned the other day that it had been a rough day for me personally.  That was the 37th anniversary of my mom’s death in a car accident.  It’s always an emotional day, but it hit me harder this year than it has for a long time, probably because of Martha Sr’s death early this year.

In addition to that, we’re in the midst of doing a massive re-arranging of the house, following the division of the household possessions.  It’s more than a bit of a juggling act, because at the same time we’re having to deal with things still here that no one in the family wanted.  The chaos of having my home environment thus disrupted is hard on me, but the whole thing is harder on my wife, who now has the unenviable task of going through all her mom’s remaining things and deciding what to do with it all.  Because with each dress, each photograph, each trinket, there is emotion, made tangible. To shed these things feels a little bit like abandoning the memory of her mom.

* * * * * * *

Whew.

I just finished going through and editing all the posts related to caring for Martha Sr, up to her death. It’s something I’ve been working on the last couple of days, part of the preparation for getting that material in shape to be a book I am collaborating on with someone else (more on that later).

Almost a hundred posts. Something like 40,000 words.

And an untold number of tears.

Wow.  She was a remarkable woman. It was a phenomenally rewarding experience. I hope that I am able to convey that.  I hope that what I have to say will help others get through, perhaps even to cherish, the time they spend caring for a loved one this way.

But for now, I’ll have a drink, and cry.

Orange windows?
July 16, 2008, 7:17 am
Filed under: MetaFilter, MIT, Predictions, Science, tech

Currently, there are two fundamental problems with solar power:

1. Manufacturing. Photovoltaics are difficult and expensive to manufacture, with exacting quality standards. Minor imperfections can ruin the electrical circuit of a cell or even a whole panel of cells.

2. Efficiency. To get maximum efficiency from solar panels, they should be mounted so as to be optimally oriented towards the sun. Ideally, they would track the sun across the sky during the course of the day, and account for seasonal variation in the sun’s path. Such tracking mechanisms are expensive to build and maintain.

Well, researchers at MIT seem to have come up with a simple way of addressing both problems.

MIT opens new ‘window’ on solar energy

Cost effective devices expected on market soon

Imagine windows that not only provide a clear view and illuminate rooms, but also use sunlight to efficiently help power the building they are part of. MIT engineers report a new approach to harnessing the sun’s energy that could allow just that.

The work, to be reported in the July 11 issue of Science, involves the creation of a novel “solar concentrator.” “Light is collected over a large area [like a window] and gathered, or concentrated, at the edges,” explains Marc A. Baldo, leader of the work and the Esther and Harold E. Edgerton Career Development Associate Professor of Electrical Engineering.

As a result, rather than covering a roof with expensive solar cells (the semiconductor devices that transform sunlight into electricity), the cells only need to be around the edges of a flat glass panel. In addition, the focused light increases the electrical power obtained from each solar cell “by a factor of over 40,” Baldo says.

(Video here.)

What they have done is to solve a basic problem with using a flat pane of glass to concentrate light around the edges of the pane, thanks to research done on lasers and LEDs. The difficulty with this approach in the past was that light energy would be ‘lost’ in passing through the glass, making such a system inefficient. But Baldo and his fellow researchers discovered that a simple application of dye or paint – they literally used orange automotive paint – on the surface of the glass did the trick. The light is absorbed by the color on the surface, then re-emitted within the pane at a particular wavelength which passes easily through the glass matrix to the edges of the pane.

This innovation is exciting for several reasons. First off, it is fairly cheap to apply such a dye to the surface of the glass, and it really doesn’t matter if there are imperfections – they’ll just disrupt the light absorption at that point, not interfere with the functioning of the photovoltaic cells. Secondly, it eliminates the need for elaborate tracking systems – any light which hits the glass is concentrated at the edges of the pane. So all you need to do is rim the edges of the glass with photovoltaic cells, and you maximize your energy gain.

A side benefit will be that the application of this technology to large buildings will generate electricity while at the same time reducing the heat load from solar radiation through windows. Say you make your windows such that they allow 25% of the light striking them to enter the building, the rest being captured for electricity generation (this can be done by controlling the amount of dye on the surface of the glass – such as is done today with tinted windows). That 25% is still plenty sufficient to help with natural illumination, but means that you won’t need to run air conditioning systems nearly as much to offset the heat load. (I just picked 25% at random – I think that the actual amount needed for illumination would be less – architects and engineers would be be able to factor this into any building’s design specs).

Of course, it could well mean that windows in our near-term future show up as being orange. Maybe I’ll need to drop such descriptions into Communion of Dreams next time I do some editing . . .
