Information and chance to win a book

What’s the most informative book you’ve read recently?

Goodness, what book worth reading isn't informative, doesn't expose the reader to something new - either in its content or in the way it treats a subject I thought I knew already? Iris Murdoch's novel The Nice and the Good informed me about the experience of judging others while questioning one's own moral sense. The setting of the novel Little Boy Lost informed me about post World War II France. If by informative you mean "packed with facts," then any of the text books I have read for school qualify for that. Take Principles of Neural Science by Kandel, Schwartz and Jessell (I should say - take it, please!). It's about 10 pounds, 1400 pages on the electrical and chemical make-up of neurons and glia, their communicative properties, and how those result in behaviors such as motor movements, remembering, paying attention, perceiving the world. It's a feast of information and an aerobic workout all in one.

Anyone who can guess what the picture has to do with the question will be entered in a drawing to win a book! One answer each, through Friday evening. One winner will be drawn from any multiple correct answers randomly. Actually I didn't really handle that properly, since once one person wrote the answer in the comments, anyone could copy it! So I am going to close the contest and declare the person who gave the first right answer to be the winner in order to be fair to her. Congratulations Isabella! I'll be in touch.
