I give this book 4 stars, but soon, I changed my mind. It deserved 5 stars on my second thought. Because I may need to read it again some day.
The author Weigang.Wan, according to himself, is an ex-physicist and the author of "100 thousands of why"(new version), which determins his words are mostly convinced by real and dependable datum. I think write articles based on effective datum is a basic requirement if the book could be decided as a benifit for human. But besides of this basic factor, Mr Wan's word are also full of new ideas, new insight. For the same and common occurrence, he may provide a totally new perspective to anaylze and reinterpret.
Just because of the first several articles of this book, I booked his special column in "igetget"(Chinese name is 得到) app. And found there he read more books and provide more ideas which are full of new veiwpoints.
I like his idea of "Deep reading"(Chinese saying is 强力研读), that is a efficient way to read a series of books, but may be tired since you have to devote more attentions and efforts.
