A book about Riemann hypothesis and its author

I am reading Prime Obsession: Bernhard Riemann and the Greatest Unsolved Problem in Mathematics. It is about Riemann hypothesis, a famous mathematical problem. I found the book quite interesting. I want to learn more about the author, Derbyshire. The following is a quote of him from Wikipedia.

Derbyshire summed up his view of American society by saying that it is "slipping into totalitarianism: into a state of affairs where to hold certain opinions is to be excluded from normal society, to be unemployable.

I read Riemann’s original paper. I now understand how the prime counting function F(x) is integrated into the equation (Page 5). But the rest of the technical details remain to be worked out.
