It's a fascinating and entertaining book. The way it highlights connections among individuals, historical events and scientific discoveries is remarkable, and I haven't read anything like it before. There was one thing that bothered me. It seemed to me that, for the most part, women were treated as props and mentioned only briefly (e.g., wives, mothers, daughters, students, lovers, innkeepers, etc.). For example, Clara Immerwhar was a scientist herself - a seemingly interesting person who had a stronger moral compass than her husband Fritz Haber - and she got about one paragraph in the book. As the book frequently veered into related characters and stories, sometimes in great detail, the fact that it largely avoided doing this with the women stood out to me. One exception later in the book was Miss Herwig, who - despite being primarily portrayed as the object of Schrodinger's sexual fantasies - was given a voice to express some important thoughts.
