(I am amazed that list of useful symbols at the top of the page doesn't include pi!)

tau = 2 pi, the measure of a full circle. There are those who argue that tau would be a better choice than pi, but I haven't found that their arguments hold much water. For every calculation it simplifies, it makes another more complex.

exactly! hence my suggestion of a dual system, or at least using tau for angles.

Tau is the name given to a constant which is twice pi, I think.

no. far from it...

it isn't. however, my maths teacher's birthday is on pi day, so i must remove her bragging rights somehow. joking aside, i believe that we should us tau for angles and pi for areas.

It should be more advertised!

Happy pi day to you a well!

May pi give us happiness in life and math!

Just a thought...Why doesn't anyone celebrate e day? 27th of January.
