Pi (π) Day has been celebrated every year on March 14th (3/14) since 1988. On this day people around the world celebrate the uniqueness of the mathematical term of Pi.
What is π anyway?
The π symbol, a Greek letter, is universally recognized as being Pi. Here’s the amazing fact about Pi. If you divide any circle’s circumference by its diameter; the answer (whether it’s a pie plate or a planet) is always approximately 3.14.
Don’t Believe It? 3 Steps to Give it a Try
- Take a string and place it on the outside of a paper plate. You just measured the circumference.
- Take a second piece of string and put it across the middle of the paper plate. You just measured the diameter.
- Compare the 2 pieces of string. Notice that you will need ABOUT 3.14 pieces of the diameter string to equal the circumference of the plate. Try it on other circles around the house. Neat, right?
Pi is a homophone of pie: the 2 words are pronounced similarly but are spelled differently and mean different things. This first celebration featured participants marching around a large circle and consuming fruit pies. Over the years, PI Day celebrations have become very popular and involve many different activities.
Take some time today to celebrate Pi Day and enjoy a piece of pie!
