Tau, which is also known as τ, is a mathematical constant that is 2 times π:

These are irrational numbers and each of the above trailing ellipses (…) represent an unending patternless sequence of digits.

In mathematics and science, 2π (τ) occurs in a lot of formulas. For example: In a circle of radius r, the circumference is 2πr or τr.

Another example is Cauchy’s Integral Formula:

which, if you replace 2π with τ, can also be written as:

Because τ simplifies a lot of formulas, there is a movement to make it — rather than π — one of the fundamental constants of mathematics.

Analogous to Pi Day, which is March 14, is Tau Day, which is June 28. I hope you enjoy this and all Tau Days!🥧🥧
