Thanks for joining us for Pi Day in 2022!
National Pi Day, also known as March 14th, is when math lovers around the world celebrate Pi, the ratio of a circle’s circumference to its diameter. Often approximated to 3.14, Pi is a number that appears everywhere in our daily life. It's used in calculations for building and construction, communications, music theory, medical procedures, air travel, and space flight, to name a few. It's encoded into everything from a zebra's stripes to a leopard's spots.
