Replace pi with tau?

Michael Hartl and Bob Palais want people to stop using pi and start using their constant tau (or τ). Tau is defined as the ratio of the circumference of a circle to its radius, while pi is the ratio of the circumference to the diameter. Hartl’s argument is that since the radius is a more important number for a circle than a diameter, the circle constant should rely on the more important number.

    fools. tau cannot replace pi. how would tou accurately double an amount that never ends? it is done in some equations but not others. these fools just want publicity and fame for changing the history of mathematics. do what a real mathematician would do and start trying to discover equations to explain things we dont know yet. these men are a waste of money and time in the scientific and mathematical world
