I hope to resolve this dispute once and for all.

But before we do that, let’s introduce our competitors:

Prominent tauists Michael Hartl, argues for the irrationality of pi in his seminal piece “The Tau Manifesto.” His principal argument goes something like this:

“When measuring angles in radians, a full circle is an ugly 2π, while it could be a clean (one) τ. This fact percolates through mathematics, depositing a 2π into various equations, and defaces our normally-elegant subject. It also makes angle measures counter-intuitive, like a quarter of a circle actually being π/2 radians.”

Pi supporters, on the other hand, are “very comfortable with pi, and multiplication by two.”2
