It seems no one mentioned the purpose of this book in the first place and I believe it's one of the important dimensions. Here is part of my review on Amazon: When I started to read the book, I only paid attention to the facts and thoughts the author provides. After a while, I found it is a book that gives readers more questions to pull them from the world they are familiar with so that they may be able to begin to discover a different world. That's the real purpose of this book. The author did a great job on this. I guess he put a lot of thoughts to prepare for the book. And this is what the original materials is for in the first place, lectures for students.
