COUNTDOWN TO TAU DAY!!!

yes

do you guys like tau now? Have i been successful?

you like tau?!?!

join my club Tau -- The Better Constant

whats that?

ok

a forum counting down to tau day

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.

Tau Day continues to approach! Today I will provide a rebuttal to a very common argument against tau; the formula for the area of a circle. We all know the famous πr^2, but, when we use tau (remember, π = (½)τ), the formula becomes (½)τr^2, the opponents of tau often argue that this key feature makes tau inferior to pi. However, this argument is flawed. To see why, we must revisit how the formula is derived. Let the function that takes as input radius r, and outputs circumference C, be defined such that C(r) = 2πr, which can be simplified to C(r) = τr. Now, to find the area of a circle with radius r, we must integrate C(r) with respect to r. This yields (Through application of the power rule), (½)τr^2, only now can we simplify to get πr^2. This example clearly shows that even when π appears alone in a formula, it still comes from τ. Also, since π = C/D, then we can plug in C/D for pi in our formula: A=(C/D)r^2, but, to maintain consistency, we must replace r with (½)D, which makes the final formula (after re-substituting pi for C/D), A=(¼)πD^2, we have to use this formula, since pi is defined in terms of diameter, this is more consistent with how pi is defined. Therefore, this argument against tau has a clear and easy rebuttal.

To continue yesterday's rant about the area of a circle, I will talk about getting the area directly from the circumference, and here is how it is possible: We know that the area of a circle is (1/2)τr^2, but what is the radius? Well, the radius is just the circumference divided by τ, so we can substitute (C/τ) for r. What we get then is A=(1/2)τ(C/τ)^2. This seems super messy, but I will clean it up in a second. To do this, we simplify (C/τ)^2 into [(C^2)/(τ^2)], but the τ^2 in the denominator cancels with the tau that is multiplying that fraction. and then we distribute the (1/2) to get A=(C^2)/(2τ). Both the calculation to get this equation and the final result are simpler using tau instead of pi. This is yet another rebuttal to the claim that tau makes circular area more complicates. TAU FOR THE WIN!!!
