What do you get when you divide the circumference of the sun by it's diameter?

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.

I used the one philosophy that has got me this far in life: You can do anything, as long as you hold your tongue right and use the right swearwords.

Very good point. I got all my jobs based on who I know.

I guess that it would be impolite to ask how many people you know then?

Why is pi day wrong? mad

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.

The backtrack quote?

Yes, your school is wise not to appoint me to do anything. I am a difficult employee. I have difficulty relating to younger people. Some are intimidated and call me sir, this is annoying. Others call me gramps, which makes me violent. Others try to mug me which also makes me violent.

And yet, you wonder why no school has hired you?

Please allow me to correct you. you should be saying happy half tau day.
