A great mix of science, history, and human insight.
The scientific treatment is understandably light, hopefully if anything that just encourages the reader to pursue their own studies; certainly, sufficient references are given.
The choice of feuds is interesting. Some are classic and expected, others surprising (e.g. Freeman v.s. Mead). In some cases it seemed the author was leaning slightly toward one side of an issue with his wording -- not just in terms of the science, but in terms of preference towards personality. The language was also occasionally overly colloquial, which made it difficult to take the book seriously at those moments.
Overall, however, this book is an enjoyable, and certainly educational read. I was introduced to fresh aspects of historical science I thought I knew well.
Definitely one for the bookshelves of any science lover, even if it isn't meet for a display case.
