Missing Gnarl. Peng Parasims.

Wednesday, March 28th, 2007

Here’s today’s idea for Hylozoic, second volume in my forthcoming cyberpunk trilogy. Having written chapter one, I’m reworking the outline. Dig this, dear reader.

The Missing Gnarl. This is where I want to end up: the birdlike alien Peng are siphoning off the gnarly computation from Earth’s matter. As a result, our clouds, waves, fire, wind, plants and minds behave more simply. What are the Peng using the gnarl for, and how are they stealing it?

[Me with my friend Gary on the roof the SF Opera house after he gave us a backstage tour after the ballet on Sunday. Scanning the sky for UFOs.]

The Peng use the missing gnarl to simulate individual Peng that thereby acquire a physical presence on Earth. These “parasims” are much stronger form of emulation than a simulation that lives within a virtual reality. Parasims have mass and physical presence. They’re the output of a heavy-duty distributed quantum computation spanning the decillion or so particles on the parasims’ “ranch.” The parasim Peng fall apart without a steady influx of computation. They’re like ice-sculptures in a blast furnace, being kept together by a zillion gnats with trowels and Slushy cones.

[At the opera there’s a prop area with for instance every kind of staff they might need for staging a show. People use staves a lot in opera-land. Keeping the actorly persona together like a parasim.]

Here’s the kicker. Due to certain inefficiencies of the emulation procedure, maintaining the physical presence of a single Peng family’s parasims requires every bit of the gnarly computation contained within a patch that covers some ten thousand square kilometers of Earth’s surface. That’s a million hectares. Putting it another way, parasimulating a small Peng family requires the resources of Peng ranch which is a square that’s roughly sixty miles on a side, like a large county. And the parasims soak up the computation in a mile of the air above the Peng ranch as well as a mile’s worth of the Earth’s crust below.

[The Los Gatos fountain wouldn’t look like this anymore. It’d be simple parabolic arcs.]

A Peng has to be very wealthy to become an Earth-based parasim. It’s the final big pay-off for a prosperous Peng life, it’s like immortality. Our Earth is like a heaven for the Peng. Although their planet Penga is forested, it’s a cooled-off, senescent, uninteresting world—like the Peng civilization itself. Earth is a Pengese post-retirement paradise. We marginalized humans are like natives bitterly squinting at a McMansion development that takes up most of our island.

[We’ll still have our bakery, but all the shapes will be perfectly simple and smooth. It’ll be hard to mix things with no chaos or gnarl working for you.]

Talk about conspicuous consumption! Huge areas of Earth are to be drained of interest to support a few smelly, pecking Peng. There’s just the one dot of bright, happy Peng gnarly amid a million hectares of dullness.

How many Peng does Earth have room for? Suppose the Peng want to live on land, not water. Earth’s surface has 150 million square kilometers of land, that is, 1.5 * 10^8 square kilometers. And I’m supposing that a Peng (or a small Peng family) requires the computational resources of a land area that’s a hundred kilometers by a hundred kilometers, a Peng ranch of, once again, 10^4 square kilometers. Doing the math, on Earth’s whole land surface we’d have room for some fifteen thousand Peng ranches. Only the cream of Pengese society need apply! Announcing the Wigfalls of West Philadelphia! Assuming the Peng won’t be moving into the intrinsically dull zones, Earth’s developers will only have room for maybe five to ten thousand Peng ranches.

Wow. I’m thinking of some great possibilities here. Peng realtors! Sell-out Earth developers!

Dot Patterns for Birthday Cards

Friday, March 23rd, 2007

So yesterday was my 61st birthday. I had some fun getting out the trusty old ruler and compass and making a Pythagorean-style pattern with 61 dots. Note that it consists of six “tetractys” patterns whirling around a central dot. Tetractys was what the Pythagoreans called the familiar bowling-alley pattern of 1+2+3+4. One can also speak of 61 as a hexagonal number.

I figured all this stuff out in 1985 and 1986; that is, how to represent many of the “birthday numbers” (from 1 – 100) as nice patterns of dots. I uploaded a very useful file about this for the world today:

Dot Patterns for Birthday Cards

[The file is the Adobe Reader PDF format; I found that with my latest version of Firefox, I needed to install the new free Adobe Reader 8.0.]

The material is drawn from my book MIND TOOLS: The Five Levels of Mathematical Reality (Houghton Mifflin, Boston 1987). Twenty years ago! I think it’s out of print but there’s used copies on Amazon.

For the last twenty years, I’ve been putting these dot patterns on almost every birthday card I’ve signed—and now you can do it too!

By the way, you’ll notice that some numbers don’t seem to have any nice dot patterns. For these difficult birthdays (or anniversaries), I turn to Plan B:

David Wells, The Penguin Dictionary of Curious and Interesting Numbers.

(I always get a chuckle out the picture on the cover because the guy looks like such a complete pinhead.)

This valuable, nay, indispensable book has an entry for—well, not all—but lots of numbers. Though, let it be said, many of the entries describe properties that are not exactly box-office gold. Like, “1/61 has decimal period 60 which includes 6 occurrences of each of the digits 0 to 9, the smallest reciprocal whose period has this property.”

The Mathematician Godfather makes you an offer you can’t understand… The virtue of my Dot Patterns for Birthday Cards is that most of them are visual patterns you can readily fasten onto. Patterns for a cheerful, uncomplicated Birthday Pig.

By the way, I first heard about Wells’s book from the mathematician Richard Guy when I jokingly asked him what, in his opinion, was the first uninteresting number. He said it would the first number I would not find in the Penguin Dictionary of Curious and Interesting Numbers.

The reason my question wasn’t entirely serious is that asking about the first uninteresting number poses a paradox (related to the Berry Paradox in the philosophy of mathematics). For the first uninteresting number is, hmm, kind of interesting.

Wells, too, is aware of the paradox, and he lists 51 as being the first number with no interesting properties, and duly notes that this makes it interesting.

The first number so truly dull that Wells doesn’t even list it all is—drum roll—54. But if you’re 54, don’t despair. It’s meta-interesting!

Rudy Video on Parallel Universes

Wednesday, March 21st, 2007

More video of me on the Ten Zen Monkey’s video site, http://10zm.blip.tv/.

Talking to R.U.Sirius about parallel universes and the infinite universe.

One thing about the blip.tv player is that at first it was popping up an ugh blinking ad! But now 10ZM has kindly turned off the ad feature for me.

To muse upon my remarks at leisure, see the Ten Zen Monkeys print site www.10zenmonkeys.com . Or, even better, see the version, carefully re-edited at my leisure, in my cumulative interviews document. As a writer, I firmly believe I should be allowed repeated edits of my life—a theme that comes up in Mathematicians in Love.

Good news, I finished the first draft of the first chapter of Hylozoic today! Only seven more chaps to go (according to current outline plan).

Last week, when I was complaining about being left out of some random anthology, I was feeling sorry for myself and even thinking thoughts like, “Why bother? Why not just quit? I’m tired of p*ssing into the wind. They don’t deserve my books!”

But then I realized that I can’t just sulk and stop writing. If I do that, I’m only punishing myself. If I quit, then “they” win, don’t they? I can’t give in to envy and resentment. Forget about the biz and enjoy the fun. I wrote something today, for instance, that made me laugh out loud for a minute.

It’s all good. And it’s spring. And tomorrow’s my birthday!

Permalink Problem. Now Pretty! Rudy and Bruce Videos.

Monday, March 19th, 2007

When I started this post, on March 19, 2007, many of the links on my blog were screwed up because I was blundering around trying to fix what I perceive as a problem with the way WordPress handles Permalinks—by default they use the “?p” method of labeling by post number instead of the more sensible “?m” method of labeling by dates. The bad thing about using post numbers instead of dates is that if a link stops working you can figure out what a date-containing link actually refers to.

But WordPress does have a “pretty permalink” option where you can use a nice format for the permalinks with year, month, day and post name. For instance, now that I’ve got this working (I am re-editing this post on March 21), this post has the pretty permalink https://www.rudyrucker.com/blog/2007/03/19/permalink-problem.

At first whenever I tried this, my site would go down. Finally I figured out that I needed to tell the genial and intrepid director of www.monkeybrains.net to put the Apache mod_rewrite service on my blog server. Those “pretty” directories don’t actually exist; mod_rewrite munges them into actual data-base code to pull the right posts out of the blog archive. Lightbulb?

Yawn, snore, hm? Is he still talking about code?

The whole issue came up because someone wrote me about a bad link into my site from the Wikipedia entry on Transrealism. For the record here’s the correct pretty link to Rudy writing about transrealism at an airport. Does anyone have the energy to fix that on Wikipedia? I don’t feel like wrestling with that, too.

On another front,

Rudy Rucker video about computation, from San Francisco. Filmed talking to R. U. Sirius. Thanks to Jeff Diehl for putting this together for the Ten Zen Monkeys site.

Bruce Sterling video about architecture from Belgrade. This is a very well made piece, with two camerapersons and an editor. Nice white out fades, and a good soundtrack. Bruce is having fun. Would be nice to see his face on, like the little video screens on gas pumps and in elevators. Like the ubiquitous dictator of Half-Life Two, but in a good way.
