Chad Orzel's competition to choose the Greatest Physics Experiment -- via the magic of the ballot box -- is almost coming to close, so go vote soon. Nominees include Galileo, Roemer, Newton, Cavendish, Faraday, Michelson and Morley, Hertz, Rutherford, Hubble, MÃ¶ssbauer, and Aspect. I totally think Galileo should win, for discovering the moons of Jupiter -- it's not every day you simultaneously demonstrate the value of perhaps the single most useful instrument in the physical sciences (the telescope), but also show that the Earth is not the center of the universe. Meanwhile, coturnix of Science and Politics, guest-blogging at Majikthise, points to his growing list of science blogs. Who knew there were so many? Remember, if you have a physics- or astronomy-oriented blog that is not manifestly crazy, we're happy to put it on the "Physics and Astronomy Blogs" list here at CV.
