Celebrate Tau Day, June 28 (6.28 in American format)

when I used to do programing one always had to change degrees to radians, and then back again if you needed it for display.

If Pi is wrong, then why is Tau defined as 2pi? Pi came first, right or wrong it's here forever.

Never forget for even a moment, this is a popular culture thing and has nothing to do with mathematics, it doesn't matter if this can slightly simplify some equations in their notation, skip calling it Tau and defining it as a 'revolution' and just use the current equivalent notation which would be 2pi or even pi2

This entire 'movement' is a pointless waste of time that could be better spent actually doing something useful.
