Pi Approximation Day 2021

Happy Pi Approximation Day!

Pi

Pi is a famous irrational number!

π = 3.1415926535…

3.14

The real Pi Day is on March 14th, so what’s with today?

Since Pi is an irrational number, that means it goes on forever, and ever… Such a long number is a little unwieldy to use in calculations. Now we have a π symbol on a calculator for easy use – but that wasn’t always the case! A popular approximation is the short and convenient fraction 22/7.

22/7 ≈ 3.142

The usage of this fraction is said to date back to Greek mathematician Archimedes.

July 22nd, when written in the in the day/month format, 22/7, looks just like the fraction!
