Over at TPM Cafe, Josh has had some cool threads with readers suggesting favorite books in a genre.  I'm going to copy him.  This week, finals end.  When they end, I'm going on a week of vacation (but, if all goes well, you folks will have some sweet guest bloggers keeping you entertained) that, if I have my way, will be about as unpolitical as possible.  With that in mind, what're your favorite nonpolitical nonfiction books?  I'm talking quirky history books (though not epic, governments-and-wars history), sociology studies, biographies (nonpolitical ones, though), and so forth. 

To get things started, I've always loved Jeffrey Schwartz's The Mind and The Brain, but best recent read has to go to  Jon Ronson's Them: Adventures With Extremists. Your turn.

Incidentally, on the off chance this conversation gave you a burning desire to set me up for the Summer, my Amazon wish list is right this way.
