80 People Who Don’t Mess Around When It Comes To Pi Day

There’s never a bad time to eat pie, but the best time is probably on Pi Day! Today, March 14th (or 3/14 in some countries), is the perfect time to channel your inner mathematician, wear some pi-themed clothing, and of course, bake a delicious pie with the pi symbol on top!

Pictolic has scoured the internet to find photos of some of the cutest and most creative ways people have celebrated Pi Day, so we’ve gathered the best pics below. Whether you plan on baking pie today or not, we hope you enjoy scrolling through these wholesome pics, and keep reading to find conversations with Anthony Persico, Founder of Mashup Math, and Candice Walker, creator of Proportional Plate!

Pi is something we all learned about in school, but if you need a refresher, don’t worry, we've got you. Pi is simply a circle’s circumference (the distance around a circle) divided by its diameter (double the length of any point on the circle to its center). It’s an irrational number that goes on forever without ever repeating itself, but most of us know it as 3.1415926535897, or simply 3.14.

Pi Day is celebrated on March 14th because, in some nations, such as the United States, dates are often written as month/day. As far as the origins of pi, mathematicians have been trying to estimate the number for thousands of years. And Babylonians and Ancient Egyptians came quite close to figuring it out. But it wasn’t until Greek mathematician Archimedes and Chinese mathematician Zu Chongzhi started working on pi that we came to our most accurate approximations (without using calculus or computers).

Pi Day also happens to be Albert Einstein’s birthday, so it’s the perfect day for math lovers around the world to celebrate the beauty of mathematics. And while the United States Congress first recognized National Pi Day in 2009, the holiday can be traced back to 1988.

Three years after Frank Oppenheimer’s death, the staff of Exploratorium, which Oppenheimer founded, met at a retreat in California to soul search and brainstorm. During this retreat, former staff physicist Larry Shaw made the connection that March 14th could be linked to the famous number pi. Larry and his wife decided to then fill the Exploratorium museum with pies on tea to celebrate the very first Pi Day.

To learn more about the importance of Pi Day, we reached out to Anthony Persico, Founder of Mashup Math, who was kind enough to have a chat with Pictolic. “Pi (π) is a fundamental constant in mathematics, representing the ratio of a circle's circumference to its diameter,” Anthony shared. 

“This relationship is significant because it applies to all circles, large and small, making pi incredibly useful in the fields of mathematics and engineering. And, since pi is an irrational number, its decimal representation is infinite, making it a fascinating concept beyond mathematics,” he explained.
