This book is a testament to how unorthodox thinking has often been at the forefront of science and the development of humanity. How some of the people regarded as our "greatest mind" had many crazy theories: some that brought innovation, and some that were arguably "bat shit" and maybe taken too far. Where would the world be without these eccentric thinkers? Dan is well-known from the "no such things as a fish" podcast, where he is often explores crazy theories with his fellow hosts. In this book he takes a very factual and complete approach, but with all of the passion that he puts forward in the podcast. Different from the "audiobook of the year" series, the audiobook is very different from the podcast, and requires a bit more attention to not lose the plot. I do, however, recommend the audiobook for anyone who does enjoys the podcast. You will enjoy the subject matter, and will be pleasantly surprised how amusing the book is.
