This book was one of the handiest and dandiest things I've ever read. It's extremely interesting, so long as you know what you're talking about. If you're not in a high level of mathematic capabilities, a lot of this will seem like junk that is interesting, but you have no clue how it works. It reveals some of the most interesting phonomena I've ever heard of, such as the flicker noise. Scaling fractals, harmonies of the worlds. This is what got me interested in astrophisics. It's a great book. Read it, live it, love it.
