Review title: Feeble attempt at classical mechanics text
Product review: Drs. Barger and Olsson need to consider explaining themselves more clearly, especially when dealing with advanced mathematical topics. Simply stating "this is a tensor" does not adequately explain the concept. An appendix of mathematical concepts is *needed*. The standard flaw of obscure derivations is included, often skipping steps or presupposing knowledge of advanced mathematics. In addition Drs. Barger and Olsson need to adopt innovations used by better textbooks, such as problems relevant to material covered, clearly worded explanations and questions, and the example.
