I can't seem to keep a copy of this book, as I'm continually lending them to friends and not getting them back. It becomes a favorite of any science-minded reader, always sublime and never dull. I don't dole out five-star reviews for books too easily, but this is maybe the best biography or autobiography I've ever read.<br><br>The discussion of scientific ideas is always light but insightful, never tedious nor glossed to the point of meaninglessness. Feynman is full of interesting stories as well, always tying in his perspective on them and their perspective on his subsequent decisions. I'm neither a physicist nor a Feynman fanboy, but I was immediately fascinated by his personality and, more so, his view of the world.<br><br>This book is, ultimately, light reading. You won't get a much deeper understanding of physics from reading it. I did feel, however, that it was a lesson on how to think about things colorfully, from first principles, without pretense or fear. How to take something like mental calculations of logs and exponents and use it as a platform for creativity, cleverness, and mischief rather than intelligence or prowess. If you're having trouble understanding what I mean by that, I suggest even more that you read Surely You're Joking.
