The Science of Discworld III: Darwin's Watch, by Terry Pratchett, Jack Cohen and Ian Stewart

ISBN: 978-0091898243

The first book explained physics of the planets. The second explained how culture evolved, and this one discusses time travel and evolution. The basic premise is that the Discworld wizards have created Roundworld, and they try and figure out how things work inside and how to fix it. In this one they try to make sure Darwin writes the right book in order to make technology evolve (sic) properly. A chapter of science is followed by a chapter of story and humour, which keeps the pace interesting. I like reading books about science ( I loved the Science of Star Trek when I was a kid ).
