Tau is a cool circle constant. However, wouldn't it be nicer to keep pi, but switch to an angle unit based on the diameter? Pi diameters around the circle is the full rotation, just like tau diameters.
The fundamental problem with pi and radians is that pi is based on the diameter while radians are based on the radius. We don't _have_ to throw out pi to get nice angles, we just have to either base both on the diameter or base both on the radius.
@mort Radians are fundamental. sin' = cos etc., but only with radians.
@wizzwizz4 Well, that sucks. I suppose we'll just have to live with it then.
@mort It's actually pretty cool. If you play around with that kind of thing some more, you'll have fun.
If you want a non-radians-based system, use fractions of a circle. 360° = 1* (or whatever symbol you're using for it).
@wizzwizz4 @mort tau, pi, diameters, radians, degrees, pfft... get rid of angles all together!
