Query: Not a recommended book for students.

I find this book quite difficult to follow. The mathematical derivation is too tedious to follow. Standard symbols are not the same found in other books, which adds to the difficulties in concentrating on the concepts the author is trying to convey. Furhtermore, you'd have to flip and back forth to understand what the symbols represent, because the author does not reiterate what they are. Bottom line: too much math CRAP!! and not enough verbal explanations. Don't be surprise if you find yourself falling asleep while reading the book.
