"This book provides an introduction to geometric algebra as a unified language for physics and mathematics. It containes extensive applications to classical mechanics in a textbook format suitable for courses at an intermediate level. The text is supported by more than 200 diagrams to help develop geometrical and physical intuition. Besides covering the standard material for a course on the mechanics of particles and rigid bodies, the book introduces new, coordinate free methods for rotational dynamics and orbital mechanics, developing these subjects to a level well beyond that of other textbooks."--BOOK JACKET.
