This professor is passionate, obviously engaged with his subject, clear and accessible. This survey moves across many big books full of ideas pretty quickly, so naturally it does not get into the more abstract and technical fine points. But to readily get a good basic feel for these ideas and thinkers (and their writing, which is critiqued a bit, and explained in light of the prevalent ideas of their times), one couldn't start at a better place.
This was a well-written and well-read book that did not drag in the least. It will particularly appeal if you enjoy science and experimental design. I think it would be almost as good even if you have other bends. The human side of the story is enjoyable while the significance of the medical breakthrough against Polio is noteworthy. The tie-ins with history events in the US with FDR and other issues in the 30's, 40's, and 50's brought the book home to me.
