While Jorgensen explicitly says in the preface this is not a history of science book, those portions of the book are the most interesting (particularly those sections that take place more than 20 years ago). A close second are the sections on biological electrical systems, which is the author's area of research. Unfortunately this is marred by sections playing executions for laughs, excursions into neuroscience that add little and significantly misrepresent the science, and a final chapter that leads off lauding a certain rich fascist. If you restrict yourself to the early chapters it's decent, but unless it's from the library as it was for me I wouldn't recommend it.
