Happy Pi Day!

 Happy Pi Day, everyone! 

This day is called Pi Day because March 14 can be written out as 3/14, and the first three digits in the mathematical constant known as pi (𝝅) is 3.14. What is pi, you may ask? Well, pi is the ratio of a circle's circumference (the distance around a circle) to its diameter (the distance between two edges of a circle going through the center). It's been found by measuring circles that the circumference is always a little more than 3 times its diameter. No matter how big the circle is, this ratio applies.

For example, if a circle is 3 inches in diameter, then the circumference will be a bit more than 9 inches. This ratio applies to any circle of any size. Also, the symbol for pi is a lowercase Greek letter that is the first letter in the Greek word "perimetros", which loosely translates to "circumference".

The first Pi Day was celebrated in 1988. It was created by the late physicist Larry Shaw, who was working at the Exploratorium in San Francisco at the time. He was inspired by conversations he had with his co-workers about mathematical constants. In 2009, the US House of Representatives passed a non-binding resolution recognizing March 14 as Pi Day. And in November 2019, UNESCO designated Pi Day as the International Day of Mathematics. 

Eating pie is considered part of the tradition of celebrating Pi Day. Get it? 

Anyway, I hope you had a wonderful Pi Day!
