Vi Hart (previously) is the fast-talking, doodling, hyper-charming mathematical vlogger whose Pi Day videos are consistently the best of the season, even when she’s pooping on Pi, she always manages to fascinate and delight.
Having comprehensively demolished Pi, Hart devotes this year’s video to building it up by baking a series of Venn Pi-a-grams that challenge the fundamental assumptions we have about pies, carbs, and pizza, and give new meaning to the idea of intersectionality.
