The New SAT, Reading, Gaming, and Jargon

Given the academic circles I run in, it’s not surprising that one of the most repeated stories crossing my social media feeds yesterday had to do with the changes to the SAT. Starting in 2015, the essay section will no longer be mandatory, and they’re going to reconfigure the reading and math sections to emphasize… Continue reading The New SAT, Reading, Gaming, and Jargon

Struggling With Sincerity

In October 1988, I trashed my parents’ basement in order to get into college. OK, the causal connection is a little indirect, but it’s there. I was applying to college that fall, and needed to write an essay to go with my application. I’ve always been able to write stuff with very little effort, so… Continue reading Struggling With Sincerity

On the Steering of Sleds

In the previous post about luge, I mentioned that there was one thing that came up when Rhett and I were talking about this, namely why there are differences in times between racers. The toy physics model I set up last time suggests that the difference between riders is only a matter of aerodynamics– two… Continue reading On the Steering of Sleds

In the Uncertain Dots hangout the other day, Rhett and I went off on a tangent about the physics of the Olympics, specifically the luge. If you’re not familiar with this, it’s basically psycho sledding: people riding tiny little sleds down a curved track at 80mph. The “featured image” above shows Erin Hamlin of the… Continue reading The Physics of Crazy Sleds

The Social Construction of Gravity

Frank Noschese's demo showing that Flappy Bird's title pixel-blob falls at the same rate as real objects.

One of the more annoying points of contention back in the days of the Sokal hoax and the “Science Wars” was an argument over social construction. This is, loosely speaking, the idea that our understanding of the world is not strictly rational and objective, but is heavily influenced by interactions with other people, and the… Continue reading The Social Construction of Gravity

Work. Finish. Publish.

A couple of days ago, John Scalzi posted a writing advice open thread, asking people to share the best advice they’d gotten on the craft of writing. There’s a lot of good stuff in there, much of it fairly specific to fiction writing– stuff about plotting, the use of synonyms for “said,” how to keep… Continue reading Work. Finish. Publish.
