The Disappearing Spoon: And Other True Tales of Madness, Love, and the History of the World from the Periodic Table of the Elements - Sam Kean Three plus.

I wondered, while reading it, who he thought his audience is. It's a bit too focused on the fun stories to interest serious science geeks, but the science is a bit too in-depth to appeal to the light reader. I'm guessing it probably appeals primarily to those interested in the history of science.

An of course I always enjoy stories about Luis Alvarez. And I got to understand more about his bubble chamber, so I appreciated that bit.
