Selena’s On-Air Debut — Mar 17, 2009

My sis­ter Selena had her on-air debut on NPR Morn­ing Edi­tion yes­ter­day, as the trans­la­tor voice of a Chi­nese woman whose fam­ily recently sought asy­lum in the United States. Lis­ten in at about 0:55.

Where did she get that excep­tional radio voice? It couldn’t have been here. Or here. Hmm… It must have been here:

This is Canine Public Radio Morning Edition, I'm Tasha.  Grrr... Ruff.  Achoo! That's my bone!

This is Canine Pub­lic Radio Morn­ing Edi­tion, I’m Tasha. Grrr… Ruff. Achoo! That’s my bone!

Con­grat­u­la­tions, Selena! You’re fol­low­ing in Tasha’s foot­steps. And you’ll pull ahead as soon as she stops to sniff something.

Singing With Blue Heron — Mar 14, 2009

linderpix-20599jpg

Tonight I had the amaz­ing expe­ri­ence of singing a con­cert with Blue Heron, one of the pre­mier early music choirs in the country.

I had an unusual week, attend­ing lec­tures on topo­log­i­cal field the­ory and writ­ing about neu­tri­nos by day, get­ting into the 1430’s groove in rehearsals by night. And the music wasn’t easy. Many of the pieces were thick with cross-relations, rhyth­mi­cally com­pli­cated, and gen­er­ally funky. I’ve had a few night­mares where I stop con­cen­trat­ing, and either I sing an incor­rect B-flat, or the see­saw mech­a­nism stops work­ing. Con­tinue reading »

Redesigning Flight Patterns — Mar 07, 2009

ff_airspace_fjpg

Wired Mag­a­zine has an inter­est­ing arti­cle about redesign­ing North Amer­i­can flight paths to improve effi­ciency. (via Rachel Mad­dow)

It’s sort of what you’d expect: flight pat­terns were orig­i­nally drawn up decades ago, and have been added to hap­haz­ardly and chaot­i­cally since then, like the streets in Boston.

The redesign cre­ates a kind of air­borne sub­ur­bia, paving the skies far out into what was the coun­try­side. The idea is that the con­trollers can get planes off the inter­city high­ways sooner, keep­ing them clear for through-traffic.

The YouTube Symphony and Bach on Speed — Feb 22, 2009

On a 5 minute break (read pro­cras­ti­na­tion vaca­tion) from prepar­ing for my oral exam next week, I came across the inter­est­ing YouTube Sym­phony: “The world’s first col­lab­o­ra­tive orchestra.”

ytso

YouTube explains:

We have invited musi­cians from around the world to audi­tion for the YouTube Sym­phony Orches­tra. The video entries will be com­bined into the first ever col­lab­o­ra­tive vir­tual per­for­mance, and the world will select the best to per­form at New York City’s Carnegie Hall in April 2009.

Musi­cians “audi­tioned” by post­ing on YouTube a video of them­selves play­ing one of a few des­ig­nated audi­tion pieces. From there, YouTube picked a few dozen final­ists and has invited us view­ers to vote on the ones we like (or give thumbs down to the ones we don’t). Con­tinue reading »

The Real Theorem Generator: a Context Free Grammar — Jan 20, 2009

I should prob­a­bly doc­u­ment the real ori­gin of the The­o­rem of the Day and Phi­los­o­phy of the Day. Cof­fee and Henry David Thoreau are per­haps less involved than orig­i­nally indicated.

nothoreauThe the­o­rem gen­er­a­tor was writ­ten by a good friend of mine, Matt Gline, as a project for CS51: Abstrac­tion and Design in Com­puter Pro­gram­ming, which we took together as freshmen.

The assign­ment was to use LISP to imple­ment a con­text free gram­mar — basi­cally a set of rules for computer-generated mad libs. The sub­ject was what­ever we wanted. Good ones from past years include computer-generated mys­tery novel­las, course-guide reports, and per­for­mance art direc­tions. Every year there’s a con­test, and Matt’s the­o­rem gen­er­a­tor was hys­ter­i­cal enough to win him lunch at the fac­ulty club. Con­tinue reading »

Dangers — Dec 26, 2008

On Jan­u­ary 13, 2008, the won­der­ful web­comic xkcd posted this car­toon.

dangers

Within hours, the comic ren­dered itself spec­tac­u­larly inac­cu­rate. Rec­og­niz­ing that it’s impor­tant that the pub­lic prop­erly under­stand the dan­gers of this mod­ern world, we pro­vide here some more recent research. Con­tinue reading »

Honda Needs a Tune-Up — Dec 23, 2008

This is the story of how Honda engi­neers screwed up a big expen­sive project with a sim­ple arith­metic mis­take, tried to fudge their result with sound edit­ing soft­ware, and con­grat­u­lated them­selves for being totally awesome.

When I was a kid, my fam­ily used to drive up to The Pin­ery in Ontario, a beau­ti­ful park by Lake Huron. Very scenic. My favorite part, though, was a stretch of road a half-hour out­side of the park. To dis­cour­age reck­less Cana­di­ans from bar­rel­ing past the houses and barns, the local gov­ern­ment carved five sets of grooves in the road before every stop sign. Drive over them, and the car would vibrate: “vbvb­vbvb… vbvb­vbvb… vbvb­vbvb… vbvb­vbvb… vbvb­vbvb.” The faster you drive, the higher the pitch.

My Dad is a musi­col­o­gist, with a par­tic­u­lar inter­est in tun­ing. So there was no way he was going to pass up the chance to exper­i­ment with this instru­ment. Every time we approached some grooves, he’d start fast over the first set, and try to slow down by the last set, to play a descend­ing scale: G-F-E-D-C. If there was no oncom­ing traf­fic after the stop sign, he’d swing over to the other side of the road and play an ascend­ing scale as we sped up. Con­tinue reading »

Hello world! — Dec 21, 2008

I’m often frus­trated by not hav­ing a canon­i­cal place to write things down, but what really pushed me over the edge is the sub­ject of the sec­ond post here. It’s nerdy. It’s kind of hilar­i­ous. I know peo­ple who will def­i­nitely appre­ci­ate it. So this blog exists for that.

How­ever, I don’t expect to be writ­ing those kinds of posts very often. I’d also like to write some notes on high energy physics sub­jects that are widely mis­un­der­stood (at least among us grad stu­dents), or not often spo­ken about, but actu­ally impor­tant. Half my life these days is fig­ur­ing out such things. I guess this blog could save some peo­ple the same trou­ble. But it’s just as much for me, since my mem­ory isn’t great, and I’d like to be able to look up answers instead of fig­ur­ing them out all over again.

Visu­als

The cur­rent theme for this blog is a slightly hor­ri­ble mash-together of my old web­site and the default word­press theme. Web design is one of my hob­bies, so expect that I’ll find some time to fix things up around here.
