If someone wrote a book claiming to have a "mathematical proof" that "1 + 1 = 3", and put a picture of god on the cover, would you buy it and promote it?
The book you disparaged is written by a real scientist and published by Oxford Uni Press. They are smarter than you, and if it were 1 + 1 = 3, OUP wouldn't have published it. Even if we disregard all this, the fact that you judged a book without reading it says a lot about your critical thinking skills.
