Great book. The author start with the idea that what would happen if suddenly all people disappeared. The authors uses Manhattan quite often, specially to link decay processes into real cases.

A brilliant idea, but very much "inflated". What I mean is that it is the case of a great idea, that the authors inflates into 100 pages or more. This book should have been 50 at most. The nice thing is that the author kept the general idea in the first part fo the book, so you can just read until you hit your limit for density of information. Mine was roughly half the book.
