Mlodinow's book is more about himself than about Feynman, whom he admits he hardly knew. There are no insights here into Feynman's character, or his personality, or the incredible story of his marriage to Arline. Nope, this book is mostly the author boasting about graduating early, writing a well-respected thesis, and being expected to excel. It should have been called "Mlodinow's Rainbow" but I guess that wouldn't have sold as many copies, would it?Don't get me wrong. The book is entertaining enough, and short enough (171 pages of large type) to be quickly devoured in a single sitting. Just don't expect there to be anything of substance about the name in the title, which is obviously a marketing ploy.
