Wheels, life, and other mathematical amusements
Martin Gardner
W.H. Freeman
Gardner has penned another whimsical, informative and totally amusing book (again).  The entire thing is a MENSA member's dream come true - a work equally at home in the entertainment and education fields.  <p>This is not just one dreary problem after another.  Instead, Gardner offers commentary on subjects as far-ranging as time, molecules, chess, cards and electricity.  And always he manages to pause for a quick puzzle or two (or three).  Terrific read.
