Doesn't get useful unti Chapter 4, after which it's great . . . but there's only six chapters.
Reviewed in the United States on November 30, 2018
This book consists of the first six chapters of Feynman's (pronounced Fine-man's) lectures on physics. The introduction and prefaces are all historically of interest. In the first chapter, he goes into a lot of discussion about atoms and, frankly, it seems more like a chemistry intro rather than one for physics. When he gets to Chapter 2, he talks about "basic physics" but most of the time is spent on quantum physics which might be a little overwhelming for someone new to physics. Kind of glosses over Isaac Newton and all those others and starts talking about leptons and such. Chapter 3--"The Relation of Physics to Other Sciences"--is of tangential interest but doesn't really get to the heart of anything. However, 69 pages in, he really gets going and becomes instructive. His explanation of conservation of energy is clear and sound, but his discussions of gravitation (Chapter 5) and quantum behavior (Chapter 6) are the best I've read and worth the price of the book. Note that Chapter 6 is essentially about the wave-particle nature of light and Heisenberg's uncertainty principle.
