Physicists Stephen Hawking and Leonard Mlodinow bring the latest thinking about the nature of reality to the general, non-scientific public in this interesting and entertaining book. The Grand Design (2010) traces mankind's progress from mythology to science. And do we really have free will? Observer created reality, quantum, string, and M theory are presented. The big bang and multiple universes are discussed.
There is no math in this book, which helps by making the theoretical concepts accessible to those without a masters in physics. The authors have presented much to think about in a very brief book (200 pages or 4.5 hours). In the end, the explanations of our reality in The Grand Design are only theories. And those theories are, so far, unprovable.
