Had William at the doctor today for a booster shot. Some waiting around, as usual, but uneventful. He's started reading "The Disappearing Spoon: And Other True Tales of Madness, Love, and the History of the World from the Periodic Table of the Elements" by Sam Kean. I read it a couple of years ago and it was very interesting. It mixes historical anecdotes about scientists with descriptions of the relevance of their science. He has such great retention that this sort of book will really change the way he enters science.
