This is one of the best books I've ever read. I am re-reading it and it has been long enough since I first read it that it's new all over again. You know that's a good book. I bought it at O'Hare years ago because I forgot to bring a book for the plane ride to Oregon. I didn't know who Mr Feynman was then but took a chance on the title and that it was on the best seller list - not that that necessarily means anything. Also, I like true stories of "curious charachter"s. He was the physicist that discovered that the "O" rings were the cause of the Challenger blowing up. But, he was more than that. He was an adventurer, an instigator, a prankster, and indeed, a very "curious charachter". This book and his other one, "What Do You Care What Other People Think?" made me aware again as an adult, that it is good to be yourself and tell the truth. It's very interesting, full of fascinating science explained for the layman, and very entertaining.
