Currently I'm reading "Surely You're Joking, Mr. Feynman! (Adventures of a Curious Character)".
And this book rocks. Really. Unique mix of enormous amount of knowledge, curiosity, humor... And
everything else you wouldn't expect from a Nobel-winner physicist.
And yeah, this is recommended reading.
The next one I'd like to read is
"Reminiscences of Los Alamos 1943-1945 (Studies in the History of Modern Science)".
