Not to mention that they seem to have chosen one of the worst possible symbols: the one that happens to represent torque. Further, it looks a lot like t, which is often used to represent turns (== cycles == 2pi radians).
There are alphabets out there other than the Latin and Greek ones, with plenty of untapped symbols.
- loup-vaillant 16y ago> it looks a lot like t, which is often used to represent turns I see that as an asset. It makes the correspondence between 2Pi and one cycle even more obvious.
- amalcon 16y agoThis is something I can't quite wrap my head around. Why would I want the symbol for a unit to be similar to a constant that I will very often use in the same calculations? That has a good chance of ruining my dimensional analysis if I finish up a calculation later. A bathroom break could convert 2 * pi radians into 1 cycle * radian, or 1 cycle into a unitless 2 * pi.
- loup-vaillant 16y agoAnd these conversions would be correct, wouldn't they? Radians are length ratios, and as such dimensionless anyway.
- amalcon 16y agoWhile not technically required, it's pretty convenient to treat radians as their own "angle" dimension. This lets you distinguish an angular velocity from a simple periodic repetition. The latter happen to rarely (never?) occur naturally, but I run into artificial ones often enough.
