    Seriously, it's just \(2\pi\). Is there a need to call it something else?

    from these pages, it looks like tau, but not 100% on that myself http://constitutionclub.org/2011/07/02/even-math-is-changing/ http://math-blog.com/2010/06/28/forget-pi-here-comes-tau/

    Also 'full circle' / '1 complete period of sine or cosine function,' etc.

    Steve is a good name too. I think Tau might have an advantage - still being a Greek letter and all that. You know how mathematical constants can be . . .

    Why do we use \(2\pi r\) when \(\pi d\) is perfectly satisfactory - except that it is not a natural result of the calculus derivation. \(\dfrac{d}{dr}\pi r^{2} = 2\pi r\). It would be counter productive to replace either \(2r = d\) or \(2\pi = \tau\)

    How about angles around the unit circle? Quarter circle: π/2 or τ/4?
