Pi is the ratio of a circle's circumference to its diameter – apple pie is a delicious pastry that comes in many different shapes and flavors.So, why do we celebrate one and not the other?
Well, it turns out you can celebrate all types of Pi(e) on Pi Day. From strawberry pie & pizza pie to those first digits of our favorite irrational number, Pi has been long celebrated as one of the most important symbols and discoveries in mathematical history.
The Greek letter “π” is a symbol that represents the mathematical constant Pi (circle's circumference to diameter), which comes out to around 3.14159 – give or take a few. There are over 50 trillion digits of Pi, which continues infinitely without repetition or pattern.
The first Pi Day was run and celebrated by physicist Larry Shaw, who was the first to connect March 14th to the famous symbol. He held the event at San Francisco Exploratorium with fruit pies and tea in 1988.
In 2009, the House of Representatives officially marked March 14 asNational Pie Day.Shaw would continue to lead Pi Day celebrations and parades until his passing in 2017.
Why all the focus on the symbol? Well, for starters: it's ancient! Ancient Greek mathematician Archimedes is credited with first calculating the estimated value of Pi.
We have him to thank for discovering a mathematical constant that has been crucial to the engineering world, as it made modern construction possible all because of what those first three digits (and the other 50 trillion) represent to the constant circumference of a circle's diameter.
Celebrations often include consuming fruit pies or having pi reciting contests. Just like a writer needs to perform spoken word poems, lovers of pi recite as many digits of the beautiful symbol as possible.
As for the consumption of pies, most math nerds gravitate towards the basics: apple, strawberry, rhubarb, and cherry pie are some of the most popular pies to chow down on Pi Day.
The significance of March 14th goes beyond Pi Day – it's also Albert Einstein's birthday! Pi Day celebrations run side by side on the renowned scientist's birthday, a delight to math lovers everywhere. So, in between the numbers of Pi, everyone leaves a little room for a round of "Happy Birthday" to commemorate another wonder of the mathematics world.
Okay, we know we said we had 3.14 ways to celebrate Pi Day, but we felt that was a little short (great math joke, though). Instead, we found 5 ways to celebrate National Pi Day that will get your calculator running!
Want to get spooky and smart this Pi Day? Although Halloween is a little far away from March 14th, there's nothing wrong with celebrating early in this versatile holiday tee.
A traditional Pi Day classic. Show off your love of great food and even greater geekdom with this cheesy tee. Be sure to get a photo of yourself eating a slice of pizza the size of your face while wearing it!
Tastes so good it'd make a grown mancry! Cherry pie might not be for everyone, but this gorgeous red fruit represents your love of the underdog.
Nothing beats a classic. Remember the smell of Grandma's kitchen during the cold autumn months? How did she always let you have the first piece of pie before anyone else? Nostalgia is a beautiful thing, and you should wear it proudly.
Cut yourself a slice of life this Pi Day and put it on your t-shirt. Pi INSIDE a pie – pieception, anybody?
Celebrating Pi Day is as easy as...well, pie! Enjoy nerding out over everyone's favorite number and stuff your face full of every type of pie imaginable. The hardest choice you'll have to make on March 14th will be between apple and pumpkin.
