I am pleased to learn that Java 19 introduced a built-in constant for 𝜏 (tau), the better circle constant

@lambdasierra I've been dealing with angles in code a lot recently, omg is tau so much simpler to think about. Using pi is like saying "There are two 180 degrees in a circle"
My theory is that pi only got popular because measuring the diameter of a physical circle is easier than measuring the radius
@dotjayne in my head I think I assumed 𝜋 got popular because of the pun on "pie" but obviously that does not make any sense if I think about if for 5 seconds
