Today is Pi Day! This annual celebration is always on March 14th and commemorates the mathematical constant of Pi (π). It is celebrated on 3/14, as it signifies the three most significant digits of Pi in the decimal form – 3, 1, and 4.
Pi Day is celebrated in many ways, including eating pie, throwing pies, and discussing the significance of the number. Schools may hold competitions to see which students can recite Pi to the highest number of decimal places.
Fun fact – MIT (Massachusetts Institute of Technology) has often mailed its application decision letters to prospective college students for delivery on Pi Day! Starting in 2012, MIT has posted its application decisions on a private website on Pi Day, exactly at 6:28 pm. They have deemed this “Tau Time”, in honor of the rival numbers Pi and Tau.
Pi has been mathematically calculated to over one trillion digits beyond its decimal point! Pi’s infinite nature makes it a fun concept to celebrate and study. Spend today learning about its origins or trying to memorize as much of it as you can.
