Flipping through it the book seems a bit lacking in substance? It is more like a picture book or encyclopedia, like "look, there all sorts of strange phenomena in physics", without being very helpful for understanding. For example, the chapter "classical mechanics" is a mere 16 pages, and contains sections like "free will".<p>If I find the time to read 1600 pages of a physics book, I think I'll rather approach the Feynman Lectures again. On the other hand, they also seem quite verbose at times - maybe some better physics book can be suggested?<p>Edit: the Feynman lectures are great, of course, a great joy to read. But they are a <i>lot</i> of text, too.
