I happened to see a few chapters online but it isn't completed. Then I try hard to find this book. I am attracted by the way of thinking and analyzing problems in this book. It starts with phenomena,then it leads you to think about it and try to understand it based on some successful and reasonable methods. You will experience how to discover the knowledge not just accept the knowledge what human beings have. I like this kind of book.  I feel like a detector when I read it.. They try to find out the truth from pieces of information. This book really inspired my interest in physical science. Science for me is more like a puzzle game. I like to unravel the mysterity of the nature. I am really happy to have it. I treat it as my favorite novel and put aside my pillow.
