Happy Pi Approximation Day

pi pronounced as pie (though a bit more dryly and geekly - yes dear, i know it's geeky but it doesn't rhyme with dryly), and not to be mixed up with the darren aronofsky's identically named psychological thriller from 1998, is a very important number.
how important i have forgotten but good old wikipedia knows. hurraa! :)
