I've wanted to try this place for years
I used to do physics and biology for a living. Now I am the director of engineering at Posterous where I code.
As any elementary school kid can tell you, pi is 3.14 ... and has
something to do with circles and their areas. Most people can even
recite A equals pi-r-squared, but their relationship to pi ends
shortly after that. As a physicist, pi was a routine part of my life
for so many years, gracing pages of problem sets and papers. Most
mathematicians and physicists can scrawl pi with a few casual strokes,
along with any number of other physical constants: e, omega, h-bar,
etc..
