Chad Orzel is a physics professor at Union College in Schenectady, NY, and has written How To Teach Physics to Your Dog, which will be published later this month. He’s also the author of a weblog called Uncertain Principles, where he published an 18 minute long video called The Bohr-Einstein debates, with Puppets. It’s well worth watching and really entertaining, although I have to agree with Orzel that the fake German accent of Albert Einstein really is atrocious (compare to the real Albert Einstein‘s accent). I’m sure I could fake a German accent better than Chad Orzel. ;-)
