Martin Gardner's Mathematical Recreations columns in "Scientific
American" virtually defined the genre of popular mathematics writing for
a generation. In this, the final collection of these columns, covering
the few years before his retirement from the magazine in 1986, he once
again uses his famously lucid style to bring cutting- edge mathematical
ideas within the grasp of the lay reader. This book will delight
Gardner's legions of fans as well as anyone with an interest in
mathematics.
