Title: There are errors in this book.
Review: The book seemed intriguing at first. However, on page 44 there is a very, very trouble mathematical error regarding the number "e" and logarithms. Namely, the author states that if y=e^x then x=log(y) (it should be x=ln(y)) which is so completely wrong that I stopped reading it. Well, I then decided that since I paid for the book, I should try again. I e-mailed the author about the error I found but he sent me a nonsensical response. I wonder about his credibility now. I wouldn't buy this book, not after such the author got such a basic math principle wrong.
