Title One Two Three . . . Infinity: Facts and Speculations of Science
Author George Gamow
Short description While not limited to mathematics, this is a great book which presents some subtle mathematical ideas in an intuitive non-technical way. I especially like the presentation of Cantor's infinite cardinality theory, which can be followed by anyone. Unfortunately, there are some mistakes. I seem to recall his presentation implicitly assumes the continuum hypothesis, but maybe he did that for clarity. It doesn't really detract from the book.
