Book excerpt: Have you ever wondered why everything in the Universe fits together the way it does? Or why we're the fortunate inheritors of a very rare planetary oasis that has the amazing ability to create, evolve and support lifeforms such as ours? Given that human life only started 200,000 years ago, how have we been able to make such giant strides in our knowledge of actions throughout the Universe from the largest to the smallest scale? Knowledge that has enabled us to put people on the Moon, look inside atoms and given us all the technological goodies that we take for granted. 18 Holes is the amazing story of how we built that knowledge over the last 2,600 years starting with Thales in the Greek City-State of Miletus right up to our current understanding by way of Galileo, Newton, Einstein and many other deep thinkers. Unlike most popular science books. the story's told in a chatty, humorous way during a round of golf by two senior citizens who've been best pals since their first day at primary school. If you're looking for a simple, non-technical insight of how far physics has taken us and why 90% of the physicists who have ever lived are alive today then this is the book for you.
