Neither of those links contain credible information, which is one reason you are receiving downvotes.

The book on Amazon was interesting. I clicked through and had a look at the reviews. Startlingly, it appeared to be rated exceptionally well, with an average of four and a half stars over two hundred votes.

The first comment on the page was a glowing review from someone who claimed to be an electrical engineer with an understanding of science.

Really?

The reviews on Amazon used to be good. Now, it's difficult to trust them. I don't think you can explain the Book rating solely through the scientifically illiterate nodding along.
