Considering that most science books focus on pointing out the errors in SF, you can see how novel this book is in its approach to explaining the science of SF.

Separate from the review, let me talk about my personal experience. This is also the book that gave me the dream of becoming a physicist. I read this book so enjoyably when I was in elementary school, and when I checked who the author was, the author's occupation was written in the author's introduction as a 'theoretical physicist.' That's when I started telling other people that my dream was to become a physicist, and considering that I didn't know much about physics at the time, it's really funny. lol
