Humble Pi: When Math Goes Wrong in the Real World

A great bedside table book - the kind you pick up after you get in bed, read a few sections of, then fall asleep. Matt read this book first, of course, and I kind of scoffed when he told me I'd enjoy it. But then, the first story was about a Pepsi advertising campaign foiled by math, so. I guess he wins. Reading about math fails was more fun than I thought it would be - but there are also some really heartbreaking stories about people who died when bridges collapsed, when there were errors in the medical field, etc.
