Feynman should have practiced the Feynman Method
This is a very good book. It's a great reminder to not take any information at face value and to make sure you understand the root of the information you're trying to learn. I also liked being reminded of the concept that, to really understand something, you should be able to teach it or explain it to a non-specialist (like a child).
These ideas are attributed to Richard Feynman. I've never really studied or read about Feynman, but he is often mentioned in certain circles as being a genius, and I was curious about him. However, whenever Feynman is actually quoted here, or excerpts of his writing are presented, they're incomprehensible jibberish. It's a stream of consciousness ramble - certainly not 'a clear exposition of information that even a child would understand.' After reading this book, I'm not impressed with Feynman at all. It's as if the concepts that people tend to attribute to him are not really things that he actually practiced. It's more like a myth. That said, my lack of being impressed with Richard Feynman doesn't detract from the key points conveyed here. It's still a very good book.
But the fifth chapter was filler (I think the author would admit that). That's why I dinged it one star.
