Book #512: The Magic Of Reality (2011, Richard Dawkins)
Turned out to be a kid's book. However, it's been a long time since I learnt any science so it was a good refresher course. Dawkins is always entertaining but don't hold your breathe while you wait for this to show up as a textbook in a school near you. Dawkins starts each chapter with what people used to think was behind each subject (from rainbows and earthquakes to evolution) before he reveals what science has discovered is the real truth. Since many people don't believe in science, this would make a hard sell as a textbook.
