I am a retired person who is interested in philosophical matters. My interest in this book was to improve my mathematics beyond vector analysis so that I could better appreciate the philosophical implications of cosmological theories. After reading this book I now feel that I can approach books on cosmology such as those of Penrose, e.g., with more confidence and understanding. The book is written in such a clear and thorough manner that I can follow Schaum's Tensor Analysis with ease. The transition from vectors to tensors is, of course, the fundamental grasp of dual base vectors and contravariant and covariant components. These are all thoroughly analysed in the text. I would recommend this book to anyone having difficulty making this transition. Students of mathmatics, engineering, or physics will find the applications very helpful, as did I. This book will save students many headaches and will substitute for much reading and effort. An excellent introduction to the subject.
