A Very Convincing Case Against Pi [Video]
hold on to your butts
It may be Pi Day, but this brilliant and thoroughly enjoyable girl maintains that π is wrong. Not because of the actual number — π still equals 3.1415 … — but when applied to circle constants (and the equation used to calculate them, C/r, or circumference divided by radius), the more elegant constant is actually 2π, or τ. Are you ready for a lesson in radians? How about one with actual pie?
Seriously, someone get this girl her own podcast, TV show, anything — She has made the case for Tau Day!
