This is a great physics primer for the lay reader. Feynman's verve shines through here, and his explanations of physics, its problems, and how it relates to the world are lucid. While physics has progressed quite a ways since the 1960s, this book primarily deals with the foundations and fundamentals of physics, which haven't changed in hundreds of years.<br><br>The only criticism I can lay against this work is that Feynman's physicalist bias shines through, especially in the chapter regarding physics' connections and implications to other subjects. Here, like any staunch physicist, Feynman lauds physics as the one true science, revealing his fundamental physicalist nature. One would do well to contrast this chapter against a work like "What Makes Biology Unique" by Ernst Mayr, where you will find a very critical refutation of this physicalist mentality
