You might think, “One more science book. Ho hum.” But you’d be missing out on a very entertaining book full of bits of knowledge worth knowing. This is written in a light, almost silly tone. In fact, at first I thought it was written with a 10-year-old audience in mind, which irritated me a bit. But as I got into it, I realized it presented some sophisticated ideas and science in very accessible ways for anyone. It consists largely of anecdotes of discovery which can be fascinating, like the woman who discovered she could smell Parkinson’s disease or the border guards who learned too late that they were training dogs to detect plastic wrap instead of the contraband inside the wrap.
