Now on ScienceBlogs: Spirited Debate with Ray and Kirk
Physics, Politics, Pop Culture
"Uncertain Principles" features the miscellaneous ramblings of a physicist at a small liberal arts college. Physics, politics, pop culture, and occasional conversations with his dog.
You've read the blog, now try the book: How to Teach Physics to Your Dog will be published December 22nd by Scribner.
"Prof. Orzel gives the impression of an everyday guy who just happens to have a vast but hidden knowledge of physics." (anonymous student evaluation comment)

Via Swans On Tea, an article in the Telegraph about the Greatest Experiments in Science.
Been there, done that, picked a winner. Over two years ago. Way to go, Torygraph.
OK, fine, they did all of science, while I was only looking for the greatest experiment in physics. But, really, can any of those stamp collectors hold a candle to Michelson and Morley? I didn't think so.

Michelson-Morley were sensitive to 10^(-8) relative in 1887. 2007 touched 10^(-16) relative. Two simultaneous interferometers observed for a year: Optical in Berlin, Germany at 52°31'N 13°20'E and microwave in Perth, Australia at 31°53'S 115°53E. An aether background could never be at rest relative to both of them and the fixed stars (e.g., ground-based star positions and via Hipparcos in space).
