Did you know that π is short for περιφέρεια 'periféreia', which is Greek for periphery? Wow! The best time to celebrate today is on 3:92 pm in 2015 Bit late for that? and περιφέρεια derives from περιφερειν, which is a mix of περι- 'peri-' which means 'around' and φερειν 'ferein' which means 'to bear'. So it's 'carrying around'?
