Celebrated each year on March 14th (3.14), Pi Day commemorates the irrational, transcendent, and never-ending ratio that’s used to represent a mathematical constant. This infinite number is crucial when describing circles because no matter how big or small, the ratio of a circle’s circumference to its diameter will always equal to pi.
In 2009, pi day, also written π or 3.14, was declared an official national holiday–one that’s worth celebrating! We’ll help you kick things off with 3 fun facts, 1 joke, and 4 activities that are certain to get you in the Pi Day spirit.

What will you be doing on 3/14/15 at precisely 9:26:53? Twice the clocks will align with the first few digits of my favorite irrational and transcendental number (3.141592653…) or π. Over 1 trillion digits to the right of the decimal point have been calculated, and they still go on, never making a pattern, never repeating.
Take any circle, that blueberry pie that your grandmother baked would be a good choice. Measure the circumference and divide by the diameter and you will have Pi, the mathematical constant that represents the ratio of circumference to diameter in a circle. You probably encountered Pi in your early mathematics education when learning the formula for the area of a circle (2πr2).
In celebration of Pi, here are a few Pi diversions to brighten your day. Continue reading “Get Ready to Celebrate Pi!”
