Its a picture of three scientists, thats it. I did not get convinced about the over arching argument.
There is a lot of scene building about each scientist and the book which is not going towards making the point.

Stylistically the book is written with a lot of flourish, the flourish distracts from the point. There is a lot of detail that is unneeded.

Skip reading this book, read the three scientists wikipedia pages instead.

Could also have been edited to an essay.
