Last workweek , YouTube ’s resident mathematical idea - cetacean , Vi Hart , bring in many of us to the topological wonder that is the hexaflexagon . If you have n’t ensure it yet , get your life in guild and go hold in it out . In fact , even if you have fancy it , go ahead and watch it again . Then reconvene with us here for troll two of hexaflexagons !

Back with us ? Excellent — then you know that last week , Hart dub October “ The Month of the Flexagon , ” and we told you we ’d keep you post on any next flexagon motion picture . This is us realize good on our discussion . In this newly release picture , Hart takes us on an diachronic journeying through some of the hexaflexagon ’s more insidious properties . For instance : why is it that different face of the hexaflexagon can be reached by passing through some surfaces and not others , and what is the immediate way to get from one side of the multi - faceted flexagon to any of its many other side of meat ?
And to all the fellow physics nerds scratching their heads over the term “ Feynman Diagram ” : no , Hart is not come to to the physicist ’s famedrepresentations of subatomic particles . As it turns out , the term “ Feynman Diagram ” was first used to report the behavior of mad bit - newspaper topographic anatomy projects . Go figure .
The Month of the Flexagon continues ! Do n’t forget to observe the annualWorldwide Celebration of Mindon Oct. 21st , in accolade of the flexagon , Martin Gardner and his Mathematical Games pillar . you could read Gardner ’s column on hexaflexagons , first published in 1956,here .
