If you haven’t read the Tau Manifesto, you really should. It may very well shatter your preconceived convictions about π and introduce you to a better, truer circle constant. It’s called tau.
Tau Angles - See the truth
There was a story once and it become the center point of tau: it makes sense. Instead of being silly and using incorrect fractions to denote parts of a circle, tau can be divided and when it is, it represents that fraction of a circle. In other words, 1/2 tau is half a circle in radians. How much is 1/2 pi? It’s a quarter of a circle. It’s ridiculous and it always has been.
So, I hope you explore the wonderful world of Tau and eat 2π! And now watch the video below, it’s fantastic!
Update
I shared this video on Facebook and I’d like to share it here too. Listen to the righteous beauty that is Tau, the true circle constant!
