The Tao of Tau

The Tau Manifesto by Michael Hartl

Welcome to The Tau Manifesto. This manifesto is dedicated to one of the most important numbers in mathematics, perhaps the most important: the circle constant relating the circumference of a circle to its linear dimension. For millennia, the circle has been considered the most perfect of shapes, and the circle constant captures the geometry of the circle in a single number. Of course, the traditional choice of circle constant is π—but, as mathematician Bob Palais notes in his delightful article “π Is Wrong!”, π is wrong. It’s time to set things right.

Nice! I always hated that it was related to diameter not radius as well, all the maths revolving round the unit circle (excuse the pun) is about radius and as such there's 2π's crop up everywhere. Unfortunately though I'm also one of those "sad sacks" that knows pi to a few hundred dp :-( --nad 14:38, 3 July 2011 (PDT)
