The title is a bit misleading, but Jim Holt runs through so many of the great philisophical questions that science has pondered for years. short chapters get to the point and offered references to thinkers and scientists I had not heard of (and I like to think I read a lot of science and philsophy books!). Essays on creativity, the possible demise of the universe, gravity theories, mathematical conundrums and the mis-naming of phenomenon are all just fascinating. I found it hard to put down and wanted to tell friends about it. The narrator is great too – has a good way with jokes to lighten some of the heavy going.
