This work will become a master piece. However, it didn't get the appreciation it deserves nowadays. Yes this book is full of mathematical equations. However, if u go through the book carefully, u will notice that the author put a lot of efforts on the presentation. Given the topics and the depth covered, the book is very well organized: Big picture is frequently highlighted; deep insights r often shared around with each discussion; the proofs r crystal clean.
To ppl who comments this book as crap, the best response is given by the author himself in Page 684 the last second paragraph! (Don't be afraid, no math there:))
