Pi Day (March 14th, or 3/14) celebrates the mathematical constant π (3.14159…) and its infinite nature, but did you know that Pi is much more than just a number in mathematics? It’s a symbol that stretches across science, art, history, and even pop culture! To mark the occasion, here are 10 fun and quirky facts about Pi and Pi Day that you might not know!
1. Pi is an Irrational Number… and Transcendental!
Pi is often called an irrational number, which means it cannot be expressed as a simple fraction. Its decimal representation goes on forever without repeating (3.14159265358979…). But it’s even more special – Pi is transcendental, meaning it’s not the root of any non-zero polynomial equation with rational coefficients. Essentially, Pi is a number that’s beyond the reach of algebra!
2. Pi Appears in Nature
Pi is more than just a mathematical curiosity – it pops up in the natural world too! Pi’s value is used to calculate the circumference of any circle. Many natural objects and phenomena form circles or arcs – from the shape of a tree ring, to the orbits of planets, to the spiral of galaxies. Even hurricanes and water droplets often form circular or spiral patterns that reflect Pi’s influence.
3. Pi Day Was First Celebrated in 1988
Pi Day has been around for a while, but it wasn’t until 1988 that the first Pi Day celebration was held. Physicist Larry Shaw at the Exploratorium in San Francisco organized the first Pi Day celebration, which included a Pi recitation contest and, of course, lots of pie! Since then, Pi Day has become a global tradition.
4. March 14th Is Also Albert Einstein’s Birthday!
Pi Day shares its date with the birthday of one of the most famous mathematicians and physicists in history: Albert Einstein (born on March 14, 1879). This makes Pi Day a perfect occasion to celebrate not just the number Pi, but also the contributions of Einstein to the world of science and mathematics.
5. Pi Has Been Calculated to Over 50 Trillion Digits!
You might think Pi’s decimal expansion is endless – and it is! In fact, Pi has been calculated to over 50 trillion digits by modern computers. While we’ll never reach the end (since Pi is infinite), mathematicians continue to challenge themselves by pushing the limits of Pi’s computation.
6. Pi is Found in Art and Architecture
Pi isn’t confined to math and science – it has also found its way into art and architecture. Some architects use Pi to design structures that involve curves and circles, like domes or bridges. Additionally, Pi art has been created, where the digits of Pi are turned into stunning visual representations. In fact, Pi Day art exhibitions and Pi-themed paintings are held in museums and galleries around the world!
7. Pi Was Known to Ancient Civilizations
Pi isn’t a modern discovery. Ancient civilizations, including the Egyptians and Babylonians, had approximations of Pi. The Babylonians used the approximation 3.125 (which is quite close), while the Egyptians used an approximation of 3.16. However, the true nature of Pi wasn’t fully understood until much later.
8. Pi Day Is a Perfect Day for Pie!
The word “Pi” is a homophone for “pie”, which makes Pi Day a perfect opportunity to enjoy delicious pies! Pi Day celebrations often include pie-eating contests, pie baking, and even pie-themed crafts. In fact, Pi Day enthusiasts will often bake Pi-shaped pies, or decorate them with Pi’s digits!
9. Pi Day Was Declared National Pi Day in 2009
In 2009, the U.S. House of Representatives passed a resolution declaring March 14th to be National Pi Day. This official recognition helped spread the word about Pi Day and led to even more celebrations across the country. The day now includes everything from Pi-related contests to math education activities, and even parties!
10. The Pi Song Helps People Remember Digits of Pi
Memorizing Pi’s digits can be a daunting task, but there’s a fun way to remember them. Some Pi enthusiasts use a special Pi song to memorize Pi’s digits. The song turns the numbers into a melody, making it easier to recall Pi’s infinite digits. There’s even a fun version of the Pi song on YouTube that recites Pi up to 100 digits or more!
Conclusion
Pi is a fascinating number that goes beyond just being a mathematical constant. From its presence in nature to its influence on art and pop culture, Pi Day is the perfect occasion to celebrate the quirky and surprising ways that Pi impacts our world. Whether you’re calculating the circumference of a circle, eating a slice of pie, or watching Pi-themed movies, Pi Day is a great way to appreciate the infinite wonder of Pi!

These are good to know. Thank you for sharing about the facts about Pi. I had no idea that March 14 is also Albert Einstein’s birthday.
Honestly I completely forgot about Pi Day. These are some great random facts for an math aficionados, thanks for sharing!! -AJ
I had honestly never heard of any of these facts about PI! What a fun idea having a song to memorize it, and I did not know it had been celebrated for so long.
I didn’t know there was a Pi Song! I always get stuck on like the 8th digit! I’ll have to look it up!
I love posts like these where I learn something and enjoyed it.
