Tau and Doubt

[deckardcanine]

The number pi’s been championed from ancient times to now,
But many people say that we’d do better using tau,
Which equals twice the pi amount. The letter stands for “turn,”
A unit of tau radians, as I was glad to learn.
The rationale for using it: For nearly all occasions,
We multiply the pi by 2 in circle-based equations.
Circumference is noted as πd or 2πr.
Diameter gets measured less than radius by far,
And tau can surely speed us up in finding a solution
To areas of other shapes and normal distribution.
The trouble is, most formulae where tau makes sense to choose
Are ones that only certain math’maticians often use.
Most people never calculate reactance of inductors.
For areas of circles, tau is more of an obstructor.
What’s more, we know a lot of tricks for calculating pi,
From centuries of thought; with tau, they’re harder to apply.
And then, of course, to western mindsets, pi is just more fun:
We treat ourselves with pastries to enjoy a cutesy pun.
