Rant time: The End of Theory? (Updated)

This one’s already been passed around the blogosphere like a cheap bottle of wine, but I feel the urge to comment on it myself. A recent issue of Wired Magazine has an essay by Chris Anderson with the very provocative title, “The End of Theory: The Data Deluge Makes the Scientific Method Obsolete.” The argument, in short, is that computers have gotten so good at processing massive amounts of data that we don’t have to understand the underlying processes that produce the data anymore: we can just let computer algorithms sort through the data and give us explanations. Anderson labels this new, model-free age “the Petabyte Age.”

This article and this attitude really irks me, and not just because I am a theorist by trade: the attitude presented here is, to my mind, so wrong-headed that it is actually hurtful to the progress of science. Let’s take a look at some of the claims.

Richard Marsh’s The Magnetic Girl

I thought I’d do a post on one more book by Richard Marsh that I’ve read, The Magnetic Girl (1903), currently only available on Google books.

The Magnetic Girl is significantly different than the other books by Marsh that I’ve discussed previously (The Beetle, The Joss, The Goddess, Curios). Although it is still undeniably a ‘weird tale’, with an unexplained supernatural element about it, it is not a horror story or a mystery: nobody is killed and no crimes are committed. The Magnetic Girl is, in fact, Marsh’s take on a comedic novel, with just a smidgen of social commentary thrown in for good measure. I give some details below the fold…

Lawn chair ballooning lives on!

Via CNN, I learn today that Kent Couch of Bend, Oregon managed to fly 200 miles from Oregon to Idaho in a lawn chair ‘powered’ by helium balloons.

Such stories have long been ‘urban legend’ fodder, ever since the first lawn chair enthusiast, Larry Walters, took off in 1982 in the Los Angeles area.  Walters ended up drifting some 16,000 feet above Long Beach, flew into the flight path of the Long Beach Municipal Airport, and ended up landing in some high-voltage power lines.  The FAA fined him heavily for the feat, but that didn’t stop other enthusiasts from taking up the chair.  The full details, including Walters’ tragic suicide later in life, can be found at Snopes.

Couch, who had obviously been inspired to do his flight by Walters’ feat, had made two previous balloon trips.  He had declared previously that he wouldn’t stop until he met his goal of getting out of state.

What sort of equipment does one take for an interstate lawn chair ride?  According to CNN,

…he carried a Red Ryder BB gun and a blow gun equipped with steel darts. He also had a pole with a hook for pulling in balloons, a parachute in case anything went wrong, a handheld Global Positioning System device with altimeter, a satellite phone, and two GPS tracking devices. One was one for him, the other for the chair, which got away in the wind as he landed last year.

For food he carried some boiled eggs, jerky and chocolate.

The final part of the story that didn’t surprise me comes at the end:

Couch flew hang gliders and skydived before taking up lawn-chair flights. He estimated the rig cost about $6,000, mostly for helium. Costs were defrayed by corporate sponsors.

Emphasis mine.  We skydivers are known for figuring out new ways to risk injury or death.

At least Couch planned for the legal logistics better than he predecessor.  Not only did he not get fined for his trip, he actually had corporate sponsorship!

What a drag: Arago’s Experiment (1810)

Note: This post is my contribution to the first-ever edition of The Giant’s Shoulders, a new blog event compiling posts concerning classic science papers.

I’ve been meaning to get back to my series of posts on relativity, but things have gone slower than I expected because of my obsessive desire to truly understand the historical scientific issues that were prevalent at the time.

In the meantime, I’ve been thinking about an interesting, infrequently-discussed topic in special relativity: the behavior of light on propagation through moving matter. This question was inspired by a comment on Uncertain Principles some time ago. In fact, one of the earliest hints of special relativity came from an experiment performed by François Arago in 1810 on ‘stellar aberration’, nearly 100 years before Einstein’s landmark 1905 paper! In this post I’ll discuss Arago’s experiment, its historical context, and the conclusions that were drawn from it.

Metropolis, complete at last (?)

Via Blake at Science After Sunclipse, I learn that a complete version of Fritz Lang’s silent masterpiece Metropolis has been found in Buenos Aires.

I’m quite excited about this.  For those who haven’t seen it, Metropolis is arguably the greatest silent film of all time, a science fiction film about a futuristic city separated into the ‘haves’ who live in glorious skyscrapers, and the ‘have-nots’ who toil underground to keep the city working.  I only got around to seeing the film perhaps 5-10 years ago, and was moved both by the amazing imagery and the surprising depth of the story.  One of the most amazing things to realize while watching the film is that all the special effects were done without the aid of CGI!

An old, old die…

As long as I’ve got dice on my mind, I should point out this glass 20-sided die that dates back to 2nd century Rome:

But $17,925 for it? I have old Dungeons and Dragons dice that look to be in the same condition. 🙂

How well do YOU know Africa?

Via The Carpetbagger Report, we learn that McCain confused Somalia with Sudan in a discussion with reporters several days ago.  This was probably him misspeaking, but he’s been doing that a lot lately and it isn’t an encouraging sign.

This report got me thinking, though: how well do I know African countries?  A  quick Google search on ‘africa countries quiz‘ brought me immediately to this interactive applet which quizzes you on the names of various African countries.

I didn’t do very well.  The first time through, I got a 65 out of 165.  The second time, i got 84.  Only a few more times through and I’ll know them all, I’m sure!

I was able to distinguish between Somalia and Sudan, though.

Very odd odds: Unusual dice

I’m still in the midst of a massive move into a new house, but everything has at least been moved from point A to point B; now the unpacking, organizing and fixing of things begins. I’ll hopefully get back to some normal blogging next week.

In the meantime, I happened across (well, ‘Stumbled Upon’) a few sets of very interesting dice for sale: Sicherman Dice and non-transitive dice. Both of these have some rather surprising and interesting aspects, and are new to me, anyway, so I thought I’d do a post!

Still moving…

Whew!  The fiancée and I are finally in the new house, after about four days of continuous work.  I’ll try and get back into the blogging swing o’ things in a couple of days, though of course we’ve still got to do a lot of unpacking in order to make the place vaguely habitable.

In the meantime, the fiancée has set a new record:  within 48 hours of moving into the new house, she’s already had to yell at kids to get off our lawn!

(In her defense, the kids were trying to slide down the sloping hill in our backyard on cardboard boxes, apparently not noticing, or caring, that netting had been stapled into the ground to prevent erosion of the hill.)

“You realize, of course, that chaos theory predicts that your criminal plans will fail.”

This one’s a shocker:  Chris Noth is leaving Law & Order: Criminal Intent, to be replaced by…

Jeff Goldblum.

On the other hand, Goldblum does have experience playing in a disturbing, psychological drama (and I don’t mean Independence Day).
