 say the _exact_ same thing using tau and
it's simpler:

Tau is a simple, straight line, and stretches the entire length of a circle,
starting from the x-axis in the positive x direction, and ending at the x-axis
from the negative x direction. So Tau / 2 is the amount of turning needed to
go half-way around the circle. Tau / 4 is the amount of turning needed to go a
forth of the way around the circle, IE. a right square.

Pi might seem easier or obvious to you because you've already been dealing
with it for years, but it still creates a situation that is more complex then
it needs to be. Tau creates a simpler unit-circle, because Tau uses the
_radius_, and we're talking about _radians_. Using something that's
calculated using the diameter, when you're talking about a unit that's
measured in radius's is asking for a mess.

say the _ exact _ same thing use tau and 
 it's bare: 

 Tau is a simple, straight line, and stretch the entire length of a r-2, 
 begin from the x - bloc in the incontrovertible x direction, and end at the x - axis 
 from the minus x commission. So Tau / 2 is the sum of turning needed to 
 move half - way around the circle. Tau / 4 is the sum of turning needed to go a 
 away of the way around the r-2, IE. a right square.
