A while back in a non-fiction post, someone recommended An Underground Education -- I read it and it was fucking fantastic. I just StumbledUpon 50 Facts that Should Change the World and plan to get it out after work because it looks awesome. In a similar but more narrowly focused vein, I got around to reading Spook: Science Tackles The Afterlife and Steal This Book and enjoyed those too.
Anyone got more good recommendations for these sorts of books? Collections of interesting facts/tips/etc?
