Good to have a good chunk of the Feynman lectures on physics online: I read a book version of the lectures at the tender age of 16 and they were what kept me going through the slightly dull physics course we had at school. I was talking about this with my mum yesterday and we agreed that tere are very few communicators that can describe complex topics as effectively in the present era. Let’s find some more.
[Update: looks like pieces of the lectures are on YouTube.]
Richard Feynman is a personal hero of mine. You´re right, he has an amazing ability to communicate. There´s a brilliant Horizon episode with him called "The Pleasure of Finding Things Out"
