the pi manifesto

A long overdue post. The Pi manifesto was written in defense of Pi and in response to

1. The original article π is wrong written by Bob Palais (published in 2000/2001).
2. The Tau Manifesto written by Michael Hartl (launched on June 28th, 2010).
3. The video Pi is (still) wrong by Vi Hart (uploaded on March 14th, 2011).

see how elegant it is to use Pi rather than Tau in Euler's..
