An excellent book about a unique man who can be called genius without any exaggeration. At first I was afraid the book will be not much more than a retelling of Feynman's own stories from "Surely You Are Joking, Mr Feynman" and "What Do You Care What Other People Think". But it is not so -- the book puts the stories into a historical and scientific context and also tells about events in Feynman's life he does not mention. Feynman's personal letters give a precious insight into his personality. The book explains Feynman's scientific endeavors and achievements, as well as numerous other areas and ideas he ventured into along the way. After reading this book, I admire Richard Feynman even more.
