Have people here seen the "Symphony of Science" videos? I was turned on to them last year, and love them. The guy who puts them together takes different scientists and science-folks speaking to music, like Carl Sagan and Jill Bolte Taylor--two of my faves. (Jill is in the new one on the brain). My favorite one is "Our Place in the Cosmos,"
