I've seen the lectures that are available online; I don't know if I caught all of them; probably not. But what I've seen is fantastic, and he is a man to be experienced. Still, barring all else, there's reading. If my TARDIS wasn't lost across the street, Chameleon circuit functioning... I'd love to go see Michael Faraday's Christmas Lectures. I have a feeling it would be a lot like Feynman.
