PI IS MILES BETTER
Tau is better than Pi

Maimonides has a brilliant take on pi,
"The ratio cannot be known. Since it is impossible to arrive at a perfectly accurate ratio, they [authors of kings] assumed a round number."

Tau naturally appears from the angle measure system called radians, in which the angle theta (Θ) is defined as the length of the arc (a) divided by radius (r). When you take the angle measure of a full circle, you divide circumference by radius, yielding tau. This means that the "Special Angles" like π/2 (a quarter of a circle) or 3π/2 (three quarters of a circle) no longer require memorization, because all you have to do to get the radian measure of the arc of a circle is take the fraction of the circle that the arc traces out, and multiply it by τ (e.g. 1/4 circle is τ/4, two thirds circle is 2τ/3), and this makes radians much much simpler. Tau is a better number because it relates a circle's circumference directly to its radius, and since a circle is defined by its radius, tau is the more natural constant.

As Tau Day continues to near, we must remind ourselves of the mistakes of the past; pi. Pi is a geometrically illogical constant because, as you likely know, the diameter of a circle has no real geometric significance. Pi is an unnatural constant which does not easily arise out of geometry. Tau, on the other hand, naturally appears from the radian angle measure system, making it a natural and logical circle constant. Another big mistake is one that most τists are guilty of: advertising tau as equal to two pi. While, numerically, it is, saying "Tau equals two pi" makes people new to tau not understand its significance. Pi alone only occurs in formulas through the division of tau by two. In the formula for area of a circle, for example, integrating circumference with respect to diameter yields (1/2)τr^2, only then can you simplify to get pi r squared. So, to correct this mistake, whenever you introduce tau to someone, say "Tau is equal to circumference divided by radius, which means that (1/2)τ equals pi". Tau is simply superior to pi in every respect.

This parable about tau provides a great analogy of how using pi instead of tau is like using a thine (which is the time between equinoxes, or a half of a year) instead of a year.
