Celebrate Pi Day 2022 with these epic NASA math challenges for March 14

If you ever feel like you’re spinning in circles, the annual pi day is a great moment to remind yourself of the power of such thinking.

NASA celebrates the famous mathematical ratio each year on March 14 (3/14), which is meant to represent the 3.14 constant that results when you divide a circle’s circumference by its diameter. (The actual number is infinite, but two decimal places works for most of us.)
