"The author takes care to introduce the new concepts in a gradual manner to make it accessible to a reader accustomed only with the standard perspective. This makes the book very suitable for self-study. ... A good list of references is provided for further exploration of each topic. This is a book which will greatly benefit a serious curious student of the subject. It deserves to be in any good library and also in the bookshelves of experts."
