It's twice the mathematical constant Pi is.

Every March 14th (Pi Day) we get tons of feedback from the Tau folks, so we thought it was time we made the Tau people a shirt that is both literally and figuratively (for Tau enthusiasts) correct.

Now, we're not necessarily fans of what's been called "the sensational vilification of a number," but we are strong proponents of intelligent discussion in all its forms. So y'all have at it in the comments (because we know you will no matter what we say up here). Just please play nice. Remember that those people you're arguing with also love math, which makes them awesome, too. Just possibly wrong.

The lowercase Greek letter Tau, the greater than symbol, and the lowercase Greek letter Pi emblazoned in white ink on the front of this black, 100% cotton t-shirt.
