Mini-Challenge: Popular Science- 6 Books In 2009

For anyone who has an interest in popular science and wants to post about their science reading. Your list can be retroactive to the beginning of 2009 or you can start from today. Install your user name in the thread title so it's easier to find your own thread and easier for others to find your thread. It's a smallish challenge that shouldn't overwhelm participants. Read more or less in the subject if you wish. All branches of science welcome. Have fun. It's not a job or a required course of studies.
