Science friends! If you were stocking the science section of a book store, what popular (as opposed to academic) titles would you put on the shelves? What books, in your opinion, are absolute essentials?
(To keep things manageable, let's say from the last ten years.)
@mcnees I liked Matter of everything - twelve experiments that changed our world by Susie Sheehy. Good balance between being clear to general and still explaining the subject matter.
