Science geek porn (no pictures)
When I was in undergrad at the esteemed Wayne State College (okay, you can stop laughing now), I would frequently sit in the library and read whatever I could find that interested me under the auspices of studying some boring chemistry text or other. Most of what I know about Linux is a result of those halcyon days but that is another (incredibly fucking boring) story altogether.
One of my favorite books from that time was Surely you're joking Mr. Feynman! I've always found scientists fascinating people but was never smart or patient enough to read their desiccated prose. Richard Feynman excluded.
If you're a science geek but aren't that smart (like me) you'll love Bill Bryson's A Short History of Nearly Everything. It's like the book version of the most absorbing A&E Biography you've ever seen except you'll learn more than your average episode about John Stamos.
