  • Ed Regis??? book Nano (a great read if you???re into this stuff) points out Feynman got half the talk from a Robert Heinlein story and half of it from a materials scientist, Arthur von Hippel, at MIT. That said, it is a pretty good speech ??? he says some really interesting things, especially about the relationship between physics and biology.
