Cover Girl HP-65

[Frozen North]

No one enjoyed Gardener's Mathematical Games monthly column more than I. I've got all his books, too. It is somewhat ironic that so many of those who were attracted to his work were also pioneers of personal computing which in turn helped end Mathematical Games by using exhaustive calculation to spoil the joys of cleverness and intuition, formerly the only ways to solve the problems Gardner posed.
