University of California Television

I’ve stumbled onto perhaps the most astounding collection of videos since TEDTalks: the “University of California” channel on YouTube.  Fully 3,575 videos are posted at the moment on topics ranging from psychology to science fiction to poetry and music.  Bill Clinton, Noam Chomsky, Ray Bradbury, and the Dalai Lama are all featured giving talks or interviews, along with countless others I have yet to even discover.

With most videos about an hour long, this trove will take some time to explore.

I’ll recommend first a talk by Stephen Wolfram, inventor of Mathematica and Wolfram Alpha:

I’ve watched only the first 15 minutes or so of this to verify it looks like the same talk I saw Mr. Wolfram give in person about five years ago.  At the time, it was the single most astonishing idea I’d ever heard.

Starting with a very simple rule for how to color in a row of boxes based on how the previous row of boxes was covered — i.e., a cellular automaton — one can obtain a “pattern” so sophisticated that it produces what, by any known measure, appears to be completely random data.  It’s so random, in fact, that “Rule 30” is used as the basis for random number generation in Mathematica.

And this talk by Douglas Adams is similarly enthralling.  He discusses several journeys he took to find and study endangered species, and what we humans can learn from them — and he does it in a speaking style that anyone who’s read Hitchhiker’s Guide will find oddly familiar:

I’ve just spent an entire hour clicking through the photography on his site, not knowing whether to be more amazed at Earth’s capability to produce weather like this, or man’s ability to capture such absolutely stunning imagery of it.

Paris: Up Close and Personal

Paris 26 Gigapixels took 2,346 pictures of Paris from atop the tower of Saint Sulpice and stitched them together into a 354,159 x 75,570 pixel panorama of the city.  Pan and zoom at your leisure.

Like in Google Earth, the zoom feature is blurry at first.  Give it a second to crisp up and you’ll be absolutely astonished at how much detail is there.  Zoom to the absolute far reaches of the image and you’ll still be able to see individual people walking around.

Special challenge: find the bright green “3:14π” sign and identify what the adjacent shop most likely sells.

Fear of Ice

The JetBlue blog is a mixture of press releases, behind-the-scenes anecdotes, corporate culture, and occasional bragging. It won some major points on February 11th, when JetBlue canceled its flights in the Northeast in advance of the latest big storm to hit the region.

With the forecast calling for icy conditions throughout the day, we decided to cancel flights rather than wait-and-see with our customers in the airports.  Why?  Because on the suckiness scale, getting a call that your flight is canceled while you’re still at home, at a hotel, or at your family or friend’s house is a lot better than getting up early, going to the airport and waiting for hours with the possibility of flight cancellation to come. Still sucks. Just a little less.

I liked in particular this explanation for why aircraft are out of position at the beginning of the day:

That would work if we could park aircraft overnight in the cities affected by weather, but we try to avoid that.  Ice would build up on the wings overnight and it would take hours to deice all of the aircraft we normally start the day with at New York’s JFK, let alone Boston, Washington’s Dulles and the Mid-Atlantic cities.  So we put those planes in warmer weather ports for the night to get them to the frozen North first thing in the morning the day after the storm, then start the operation from that point.

I love logistical challenges like this, and I’d probably enjoy figuring out how to reposition aircraft in this manner to have the least impact on operations.  I don’t envy the planners who have to endure (albeit indirectly) the ire of stranded travelers who are entirely too willing to blame their airline for the weather, though.

Food, Shelter, and Internet

Google generously sponsored free wireless Internet access at 54 airports during last year’s holiday season, including Boston’s Logan International.  This made hectic holiday travel a little more fun, and surely got Google a metric boatload of ad impressions on all the “wireless jail” pages we see when first connecting.

I don’t mind terribly paying for the resources I consume, as a general rule, but the pricing model for Internet access at airports is a terrible fit for most people.  At Logan, the cost was $7.95 for 24 hours of access.  On its face, that’s not bad.  But of course, most people aren’t spending 24 hours in the airport; they’re just checking their e-mail in the one hour buffer surrounding their flight.

Well, good news, citizens of Boston: Massport has arranged to keep the Internet free at Logan — indefinitely!  Unsurprisingly, use of the wireless network grew sixfold during Google’s sponsored access, and Massport is finally ready to continue offering the third basic element of human survival at no cost.  Excellent decision.

Logan Wireless Internet

I love the number of shared libraries that appear in iTunes at the airport.  My favorite selection this time: “Stud Beefpile.”  I didn’t dare look to see what was in that one.

The Four Quarters

I stumbled upon The Four Quarters on YouTube this morning and immediately had to play every video they’ve made.  Among my favorites: Downtown, Lullaby of Broadway, and the “Teenager in Love, Lollipop, Earth Angel, Sh-Boom” medley.

Don’t be surprised when you open the “National Anthem” video and hear an off-key “Oh” at first.  It’s actually on key, it’s just followed by “Canada” instead of “say can you see.”  (That was a discouraging little realization of some intrinsic assumptions I apparently make about the universe.)

Roxxxy the Robot

In the Business section of this morning’s Boston Globe is this blurb from the Associated Press:

A New Jersey company says it has developed “the world’s first sex robot,” a life-size rubber doll that’s designed to engage the owner with conversation rather than lifelike movement.

So many punch lines and so little time!  Reading on:

The dark-haired, negligee-clad robot said “I love holding hands with you” when it sensed that its creator touched its hand.  Another action, this one unprintable, elicited a different vocal response from Roxxxy the robot.

Oooh.  Saucy.  Now, talk to us about the “sex” part of “sex robot” a little:

It has sensors at strategic locations and can sense when it’s being moved.  But it can’t move on its own, not even to turn its head or move its lips.

No further questions, your honor.

The Robotic Waggle Dance Phenomenon

I’m reading You Are Here: Why We Can Find Our Way to the Moon, but Get Lost in the Mall by Colin Ellard.  It’s a fascinating study of how humans and other animals navigate, from simple tasks like moving across a crowded room to complex feats of worldwide and celestial navigation.

One section describes Karl von Frisch’s research with bees in the 1920s.  After finding food, bees return to the hive and perform a “waggle dance,” which von Frisch deduced was a way of communicating the food’s location to other bees.  Perhaps understandably, some skepticism met this claim.  Ellard writes:

[O]nly very recently have advances in technology enabled researchers to provide what seems like ironclad evidence for the key role of the waggle dance in bee navigation.

In 1989 a team of researchers at the University of Odense in Denmark built a dancing robotic bee.

I love my chosen profession, but I do sometimes think meetings would be more fulfilling if, when someone disagreed with my point of view, I could say something like, “You’re wrong, as I shall now demonstrate with this dancing robotic bee.”

Citizen Soldiers

I recently finished Stephen Ambrose’s Citizen Soldiers about World War II.  It’s an interesting read throughout, but my absolute favorite story comes from the introduction.  Ambrose describes the Lieutenant Waverly Wray of Company D, 505th Parachute Infantry Regiment, 82nd Airborne Division, commanded by Colonel Ben Vandervoot.

Lt. Waverly Wray

Lt. Waverly Wray

After jumping into Normandy, he began crawling through the sunken lanes to reconnoiter the German positions surrounding them.  He came upon a group of eight German officers surrounding a radio — officers who turned out to be leading the counterattack.  Wray jumped through the hedgerow and ordered them to surrender.

Seven instinctively raised their hands.  The eighth tried to pull a pistol from his holster; Wray shot him instantly, between the eyes.  Two Germans in a slit trench 100 meters to Wray’s rear fired bursts from their Schmeisser machine pistols at him.  Bullets cut through his jacket; one cut off half of his right ear.

Wray dropped to his knee and began shooting the other seven officers, one at a time as they attempted to run away.  When he had used up his clip, Wray jumped into a ditch, put another clip into his M-1, and dropped the German soldiers with the Schmeissers with one shot each.

Wray made his way back to the company area to report on what he had seen. At the command post he came in with blood down his jacket, a big chunk of his ear gone, holes in his clothing.  “Who’s got more grenades?” he demanded.

Vandervoot later recalled that when he saw the blood on Wray’s jacket and the missing half-ear, he had remarked, “They’ve been getting kind of close to you, haven’t they Waverly?”

With just a trace of a grin, Wray had replied, “Not as close as I’ve been getting to them, Sir.”

Ambrose’s Band of Brothers (on which the HBO series of the same name was based) is more compelling overall, but because it tells the story primarily of a single company of paratroopers it necessarily offers a limited view of the war.  Citizen Soldiers gives a more complete overview, but naturally at the cost of some finer detail.  Clearly the only reasonable plan is to read both.

The picture of Lt. Wray comes from The U.S. Airborne During WW II, which came up in a Google search for Wray’s name, and which I now must absolutely explore in greater depth.

Jim Denevan

Jim Denevan carves enormous art pieces in the sand of deserts and beaches.  On a canvas that nature is prepared to wipe clean with wind or water the moment it’s been filled, he creates artwork so large it can only be appreciated from the air (at least in a lot of cases).

One basic example is this pattern on a beach with a tiny person poised in the center:

The Art of Jim Denevan

Other pieces are abstract, simple, or just daunting.  My favorite has to be this one.
