Critical discussion of string theory and the academic system

The first part is dedicated to quickly trace the history of physics and of the problems facing modern physics and the various attempts that have been made to solve -out quantum theories of gravitation.
The second part is a critique of string theory and its lack of results.
The third presents the other quantum theories of gravitation.
The fourth is a critique of the American academic system in the way of doing science.

Being an avid reader of Brian Greene, one is led by his enthusiasm. But after reading this book, one realizes that he does not dwell much on the black spots of the string theory.
Smolin trying to show everything that is wrong and it is very interesting to have a critical view on this theory.

I enjoyed this book and, even if there is no mathematical equations, the debate is quite technical at times. So if one is not too familiar with certain concepts, we risk losing -prévoyez several readings!

In any case, I advise you and I look forward to his new book because I discovered an author readable.
