"Fermat's Engima", by Simon Singh (First Anchor Books Edition, Oct 1998)
One Sentence Summary: Several hundred years of math gossip, now with layman's proof of Fermat's Last Theorem!
What I Liked About It: Does a good job of slowly building up to the layman's explanation of the proof of Fermat's Last Theorem ; Really interesting to see the 'human side' of math history
What I Disliked About It: It took a while to sink in that the book was slowly building up to the proof on purpose, as opposed to merely being distracted by tangents.
"My Life As A Quant", by ??? (????)
One Sentence Summary: I coulda been a (physics) contender!
What I Liked About It: Fascinating autobiography of someone who initially wanted to go into physics, but then realized he wasn't going to ever join the pantheon of great physicists.
What I Disliked About It: After a while it has kind of a 'slide show' feel to it - I think it almost has too much of a 'diary' feel to it, without enough insightful commentary.
