Photoelectric Follies

I spent most of yesterday helping out with an on-campus workshop for high school teachers and students. Seven high school physics teachers and seventeen high school students spent the day doing a half-dozen experiments to measure various physical constants. I was in charge of having them measure Plack’s constant using the photoelectric effect. The actual… Continue reading Photoelectric Follies

Grading Medical Students (and More on Grade Inflation) — Crooked Timber "But, if grade inflation is supposed to be analogous with price inflation, rising grades do not, in themselves, constitute inflation. Rather, grade inflation occurs when grades rise relative to the quality of the academic performance of the students. And because we do not keep… Continue reading links for 2008-12-07

Yesterday, one of the big stories was CNN axing its entire science unit, such as it was, which drew comments from lots of blogs (and more whose links I can’t be… Continue reading Science Is Interested in You

She enjoys being held upright in a standing position,… Continue reading Thursday Baby Blogging 120408

If Wishes Were Horses We’d All Be Eatin’ Steak

There’s a kind of tradition in theoretical physics of wacky “what if” papers. The whole “wormhole” thing is an example of this in action– somebody noticed that the structure of General Relativity would allow you to make tunnel-like structures between points in space, and then asked what you would need to make such a structure.… Continue reading If Wishes Were Horses We’d All Be Eatin’ Steak
