"…a very impressive book."-Australian and New Zealand Physicists"The clarity of the presentation is enhanced by explicit calculations and diagrams; the proof of a theorem is given only when it is instructive and not very technical. There is also a large number of exercises and problems, and last but not least, an index … superb layout…"- Zentralblatt fur Mathematick un ihre Grenzgebiete"I believe that the book will not only boost modernization of the traditional courses of theoretical physics but will prompt the specialist in topology and differential geometry to have a closer look at the applications. So I welcome this second edition."-Christopher Gilmour
