Best ResponseYou've already chosen the best response.0Steve 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 . . .

Best ResponseYou've already chosen the best response.0Why 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 \(2\pi = \tau\)
