The Tau Manifesto

Is Pi wrong? continued...

The Pi Manifesto defends the value of Pi @ 3.14. 

Is Pi wrong?

Recently a movement called Tau has argued that Pi as 3.14 is incorrect.  Their belief stems around the idea using the radius of a circle to define the circle constant rather than it's diameter.  By using the diameer, mathematicians calculate Pi to be 3.14; since there are two radi per diameter the Tauists argue Pi to be 3.14 x 2 = 6.28.
