"MacCluer's book ... is calculus 'done right.' And in a mere 162 pages and 1.1 lb! ... The approach is axiomatic, but the writing style is breezy and inviting. The student will see right away that this is not simply a rehash of material seen in high school--there are some genuinely new ideas here. These include topology, compactness, quantum mechanics, differential equations, and a host of other fascinating topics... This could be an exciting book from which to teach. This is a book that will allow the instructor to build a fascinating course in a variety of different ways. Teaching from this book should be a joy for all."--Steven G. Krantz, UMAP Journal
