Historical Note: This video is based on a true story. Arthur H. Stone really did invent the hexaflexagon after playing with the paper strips he’d cut off his too-wide British paper, and really did start a flexagon committee (which we’ll hear more about in the next video). The details and dialogue, however, are my own invention.This video is based on, and in honor of, Martin Gardner’s first Mathematical Games column from 1956, “Hexaflexagons.”
October 21st is Martin Gardner’s birthday, which is why every October the recreational mathematics community celebrates his life and work. | Source: Vi Hart
