A graduate level text based partly on lectures in geometry, mechanics, and symmetry given at Imperial College London, this book links traditional classical mechanics texts and advanced modern mathematical treatments of the subject. Throughout the text the exposition is very clear, and this is in big part due to the extensive use of detailed examples, which is probably one of the strongest pedagogical points of this text when compared with other text books with similar subjects and targets...This makes this text the starting point for any researcher interested in getting started in the field of geometric models for continuum systems.
