In this test for use at the introductory graduate level, Johns (physics, San Francisco State University) provides a mathematically sound treatment of the foundation of analytical mechanics and the relation of classical mechanics to relativity and quantum theory. A distinguishing feature of the book is its integration of special relativity into the teaching of classical mechanics. The book will also be useful to those who study analytical mechanics to prepare for a critical exploration of quantum mechanics. Comparisons to quantum mechanics appear throughout the text.
