You mean pi should have been defined as the ratio of the circumference of a circle to the radius, instead of to the diameter? Probably, yeah :)
Better yet, I think the unit of angle we should use is the 'full rotation' ('rot'?)
So instead of 360 degrees, or 2pi radians, we say 1 rot.
The many factors of 2pi in common equations imply we got this wrong.
- martincmartin 7y agoI think OP is suggesting that we change the definition of radian, not Pi.
- Ono-Sendai 7y agoit's a bit ambiguous. Of course the radian has that definition for a particular reason, 1 radian being the angle such that the arc length equals the radius.
- SamBam 7y agoI don't believe substituting tau for 2-pi requires redefining either pi or radians. Rather it simply changes what you say you are multiplying by: instead of a circle being 2-pi radians, it's tau-radians. These are both saying the same thing, without changing pi or radians.

- Ono-Sendai 7y agoYeah my proposal differs a bit from the tau proposal, although there are some similarities.
- amelius 7y agoI like this idea of "rot" more than "tau", except "rot" is already a stand-in for "∇⨯" in mathematics.
- Ono-Sendai 7y agoMaybe calling it a 'turn' instead.
- SamBam 7y agoThat has been a proposal, and is part of the nice aspects of using τ instead of π. > The second reason is that τ corresponds to one turn of a circle, and you may have noticed that “τ” and “turn” both start with a “t” sound. https://tauday.com/tau-manifesto#sec-one_turn https://tauday.com/tau-manifesto#sec-one_turn
- Archit3ch 7y agoBut where do you stop? Do we need a name for pi/2? How about pi/12?
