[math-fun] A Plea for Pi

People, please put the pi back in Pi Day. Somehow, it has lost its meaning in the commercialism of the aggressive baking industry, and people just gorge themselves on pie instead of thinking about how it all started. One day, a small number, rejected by the cabal of rationals, stood up on its wobbly two legs and announced to the world "I am the Ratio". Tell people that today you celebrate the number and not the pastry. Hilarie
