This segment on David Suzuki’s The Nature of Things features Martin Gardner, a math and science writer who wrote a regular column for twenty-five years in Scientific American and published over seventy books. Gardner’s influence in these fields at applying recreational mathematics, magic, puzzles and games is absolutely fascinating. The episode covers everything from the math involved in the tiled pattern forms of M.C.. Escher’s work to perfectly shuffling cards in a sequence that brings you back to where you started.
