I really liked this until the last chapter. It’s a great book where the reader is introduced to a variety of scientists who are interviewed by the author. It’s a good introduction to their ideas and work. Unfortunately the last chapter is the author pretending to interview Leonardo Da Vinci in a very hammy manor. The author adores him and has written another book about him, but after a bunch of well put together interviews this pretend interview dragged the entire book down for me, it wasn’t enlightening or entertaining, just annoying and embarrassing.
