"As an undergraduate math major, I studied various areas of mathematics as if under a sequence of microscopes. I had no clear picture of what mathematics as a whole was about. Here is a book, based on ten great puzzles, that provides that much needed view from 40,000 feet. Big concepts such as topology, combinatorics, logic, the infinite, and many others come into clear view at this altitude. For those seeking more detail, there is always the option to land and explore a host of mathematical issues, puzzles and related references. Danesi’s approach to relating difficult material is seductive."
