Like a good magic trick, a clever puzzle can inspire awe, reveal mathematical truths and prompt important questions. At least that is what Martin Gardner thought. His name is synonymous with the legendary Mathematical Games column he wrote for a quarter of a century in Scientific American. Thanks to his own mathemagical skills, Gardner, who would have celebrated his 100th birthday in October, presented noteworthy mathematics every month with all the wonder of legerdemain and, in so doing, captivated a huge readership worldwide. Many people—obscure, famous and in between—have cited Mathematical Games as informing their decisions to pursue mathematics or a related field professionally.
