A Very Convincing Case Against Pi [Video]


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!

    I couldn’t follow all of it because I’m a girl and when Barbie tells me math is hard I believe her (kidding) but this was a really well done video. Also the need to eat Cherry Pie now dominates my every thought. Thanks.

    I love this girl. All her doodle-math videos are enjoyable and charming if not always within my realm of understanding. I’m all about Tau Day now!
