Why do we make such a big deal out of pi? Because pi is a big deal. This irrational number that begins with 3.14 and goes on forever helps us understand so much about our universe. We first learn about pi when measuring circles, but pi is also used to talk to satellites, to measure how fast and powerful a computer is, and even to study the structure of an eye. Pi is used every day to make calculations in physics, engineering, modern construction, space exploration, and so much more. Pi is all around us, and it helps the world go ‘round (and ‘round).

Pi is so beloved that it has its own holiday: Pi Day. Observed each year on March 14 (3.14), Pi Day celebrations honoring this important mathematical constant include “pi-themed,” circle-shaped food such as pizza, fruit pies, cookies, cupcakes, crackers, etc., activities featuring circular shapes, and pi digit memorization contests.
