Very weak science
I agree completely with M J Edelman's review. He gave it 3 stars; but, despite skillful writing, I can't give it more than 2. I'm a mathematician with a strong background in physics, and very much agree with Edelman that Ferris is simply repeating a lot of what he has absorbed, much without understanding it well. I was led to believe from the Amazon profile of Ferris that he was a scientist -- that's a natural conclusion when he is credentialed as an emeritus professor from U of C Berkeley, who has taught astronomy at 4 universities. But he isn't a scientist at all; he has only a bachelor's degree in journalism.
