All right, I can concede that in higher math, the use of tau doesn't greatly impact anything (although it still does). The point though, is that pi is fundamentally incorrect as the so-called circle constant. Furthermore, the use of tau would significantly change teaching. Trigonometry and radians would become so, so much easier to grasp. For example: sin 2t. Well, that's 2 revolutions of a circle, which means we're back where we started. Hence, 0. Logically sound: it's much easier for a student to grasp that t=1 revolution than 2pi=1 revolution

I can't believe it ... they're right!

It also applies to Buffon's needle: it's not 2/π; it's 1/τ, or τ^-1! Tau makes the world so much simpler!

Too bad it's already used to represent torque.

And to that argument, I say, what about e? No one seems to have issues with the fact that e represents both Euler's number and the charge of an electron

e (the number) is italicized, e (an electron) is not
