Richard Feynman's "The Pleasure Of Finding Things Out"
I picked up the above, literally, for free, at Pittsford Community Library, as a six-cassette audio book among paperbacks that were being given away. (Not above is the dissenting physicist Freeman Dyson's forward.) Richard Feynman was introduced to me by the nerds I taught at the Pohang University of Science and Technology, who loved the man "this side idolatry." He taught down the road at another good school, Cornell University.
