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:

Storm Photography

These photographs come from Mike Hollingshead, a storm chaser in Nebraska:

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.

Danger! Hula Hoops!

It’s an interesting week for me and crosswalks.  I caught this sign in front of Terminal E at Logan Airport this afternoon:

Hula Hoop Crosswalk

Hula Hoop Crosswalk

I’m not sure if this means drivers need only stop for passengers using a hula hoop, or that pedestrians not using one are forbidden from crossing here.

(While the cynical among you will surely dub this vandalism — and my cell phone camera seems to lend credence to the theory — it looks awfully convincing up close.)

Beware of Curb

I like this sign down by the Boston College T stop, aimed directly at the trains leaving the yard:

Beware of Curb

Beware of Curb

I’m not a railroad engineer, but I image that simply refraining from building any curbs across the tracks in the first place would alleviate the need for such signage.

The Boston College station was renovated last year. While the shiny new platform and shelter are a welcome change from the aging infrastructure they replaced, the logistics of the whole affair are just embarrassing.

Outbound trains stop just short of the sidewalk (or crosswalk, more properly) cutting across the mouth of the rail yard, affording easy access to passengers running west to catch their trains.

The new design erected a short railing ostensibly blocking direct access to trains, and forcing passengers to overshoot the station and backtrack down steps (or a ramp) to the platform. This is almost certainly meant to be a safety measure keeping harried commuters from running in front of trains that are about to move, but realistically a small segment of railing will do little to prevent that.
