Pi Pie
Pi Day is today (3.14)! Larry Shaw started Pi Day in 1988 when he was a physicist at the San Francisco Exploratorium. Today schools across the country will host Pi Day activities and then students might eat slices of pie. Pi is the relationship of a circle’s circumference divided by its diameter. An irrational number, pi has been calculated to 62.8 trillion decimal places. Several wonderful websites are devoted to Pi Day, but probably the best one is the Exploratorium site at: Pi Day.
