If you want to read a great book, his autobiography, "Surely You are Joking, Mr. Feynman" is a real treat. He writes very conversationally and down to earth.
I took a course from him in 1985. Dr. Feynman was able to reduce some pretty complicated physical concepts down to something more understandable. Not everything in physics can be in some way simplified, but he did what he could to provide analogies in other branches of the subject. This made various topics come to life in a manner other professors I had never could accomplish.
I had meant to say earlier, the other hilarious story (poignant too) from the book was the story of how (right after the Manhattan Project) he failed his draft physical for (get this) mental reasons!
