As many of you may know, I am a Feynman addict. This is a wonderful video...I also highly recommend the many books on him--probably my favorite is Gleick's Genius: The Life and Science of Richard Feynman.

I'll second that recommendation PG, although 'Genius' is maybe best left unread by those who resent the humbling of one's ego.

Freeman Dyson was in awe of him, and Gleick pretty much sums up the difference between Feynman and Gell-Mann in just a few words:

"Physicists kept finding new ways to describe the contrast between them. Murray makes sure you know what an extraordinary person he is, they would say, while Dick is not a person at all but a more advanced life form pretending to be human to spare your feelings."

I'd love to get his take on the state of the world today.
