Pi Approximation Day 2021: 10 Fun Jokes About The Mathematical Constant

Pi enthusiasts have another excuse to celebrate the mathematical constant today as July 22 marks Pi Approximation Day.

Known in some form for almost 4,000 years now, this irrational number is the ratio of the circumference of a circle to its diameter. One of the things that make it rather popular is the fact that it essentially goes on forever. It is, however, approximated to be 3.14.

The occasion is quite like Pi Day, which is celebrated on March 14 (3/14) each year, but it is celebrated using a different date format. Instead of 3.14, Pi Approximation Day celebrates pi on 22/7, the other approximation of pi.

Also known as Casual Pi Day, the idea is to celebrate math that this special number has allowed people to do in its long history, on this holiday.

Simple Ways To Celebrate Pi Approximation Day

To celebrate the infinite number, people can try memorizing as many digits of pi and perhaps challenging their friends to see who can memorize more. So far, the Guinness World Record for the most pi decimal places memorized is a whopping 70,000 digits. It was achieved by Rajveer Meena of Vellore Institute of Technology (VIT) in India.

Those who are quite skilled in the kitchen may also bake a pie to celebrate and perhaps even decorate it with the Greek letter denoting pi on top. Others may also want to research the many ways NASA uses pi.
