'Rarely does one come across a mathematics book with such breadth and insight. Dr. Benson's book contains valuable information--not only for curious students and laypeople --but also for seasoned researchers. Particularly fascinating is the curious range of topics, from fractals and fiendishly difficult games to the mathematics of precariously-leaning brick towers! All the topics are sure to stimulate readers' imagination and sense of wonder at the incredible vastness of our mathematical universe.' --Dr. Clifford Pickover, author of Time: A Traveler's Guide'A useful book, offering a rich collection of interesting and enjoyable mathematics.' --Reuben Hersh, author of What is Mathematics, Really?'Donald Benson shows what mathematicians mean when they speak of the beauty of mathematics -- an artistic beauty of logical elegance and occasionally surprise.' --Keith Devlin, author of The Language of Mathematics: Making the Invisible Visible and Life by the Numbers
