There's a mistake on almost every page! (Probably typeset by Mr. McGoo.) If it wasn't for all the mistakes, this book would be very promising. The chapter on relativity is real bad though, so be careful. Also, it's very obvious that Dr. Chow copied many sections from Marion and Thornton almost verbatim. The chapter on Lagrange's method needs some improvement, especially on its coverage of the calculus of variations and Hamilton's principle. Hopefully, Dr. Chow will significantly improve the second edition. Wait until then
