Pi Day is observed every year on March 14th. The date 3/14 resembles the first few digits of pi (3.14), hence March 14th is always Pi Day. Global mathematicians, educators, and individuals came together to celebrate this unique occasion honoring the mathematical constant π (pi). The fact that this year’s celebrations included new elements due to developments in education and technology made them especially significant. People of all ages were interested in learning more about the intriguing field of mathematics through virtual events, live-streamed lectures, and interactive online activities. National Pi Day 2024 highlighted the enduring attraction of mathematics and its capacity to unite people in celebration of the beauty of numbers through pi-themed art displays and online pie-baking competitions. As individuals shared their love for Pi on social media, the day served as a reminder of the importance of fostering curiosity and appreciation for mathematics in our communities.

At Universe Public School, teachers and students were excited for a day full of mathematical celebration and wonder on National Pi Day 2024. The school has organized a series of engaging activities to immerse students in the exploration of the mathematical constant π. Students engaged in pi-related activities, challenges, and competitions that focused on making math fun and engaging in the classroom, creating a buzz of excitement. The math department at the school arranged virtual tours, and guest lecturers, and held special workshops to help kids better grasp the importance of pi in a variety of professions.

Pi Day is a yearly celebration of the mathematical constant π.  Over thirty years ago, in 1988, physicist Larry Shaw organized Pi Day’s inaugural large-scale celebration at San Francisco’s Exploratorium. Since then, the celebration has only gained momentum. In 2017, the US House of Representatives recognized Pi Day, and in 2019, the UN recognized it as well, making it an international celebration. Today, Math teachers around the country celebrate Pi Day in the classroom.

What is Pi (π)

The mathematical constant pi (π), which is pronounced “pie,” represents the ratio of a circle’s circumference to its diameter. It’s a special number because, no matter how big or small the circle, this ratio will always be the same. This makes it a fundamental constant in various fields like Physics, Mathematics, even art and engineering. 

Here are Some Key Things to Know About π

  • It’s an Irrational Number: This indicates that it cannot be stated as a straightforward fraction and that there are no repetitions in its decimal representation. 
  • Its Value is Approximately 3.14159, often remembered as “Pi to the third power.”
  • It’s Used in Countless Formulas and Calculations: π appears frequently in science and engineering, from determining the area and volume of circles to comprehending wave dynamics and planet motion. 
  • It’s Celebrated on March 14th (3/14) as Pie Day, a fun day to appreciate Math and indulge in circular treats like pies.

History of Pi Day

A fascinating blend of mathematical interest and good ol’ American fun is the history of Pi Day! This is how it happened:

1. Early Seeds 

  • Pi Day wasn’t even the beginning of the preoccupation with π. Calculations utilizing approximations of π were already utilized by ancient civilizations such as the Egyptians and Babylonians. 
  • In 1706, an important development in mathematical notation was made when William Jones employed the Greek letter “π” for the first time to express the ratio of a circle’s circumference to its diameter.

2. The Birth of Pi Day 

  • The credit for Pi Day’s origin goes to physicist Larry Shaw. when he was employed at the San Francisco Exploratorium in 1988, he discovered that March 14th (3/14) coincided exactly with the first three digits of π (3.14).
  • Shaw observed the day by marching around a circular exhibit and then indulging in fruit pies. This playful event marked the first official celebration of Pi Day.

3. Spreading the Pi-Love 

  • The Exploratorium was not the only place that Pi Day became popular. Social media, internet discussion boards, and news stories all contributed to the day’s awareness-raising efforts and math appreciation theme.
  • Museums,  libraries, and science centers started hosting Pie Day events with workshops, lectures, and fun activities for all ages. 
  • The most delectable way to remember a circular constant is with pie, and pie-baking became a daylong custom.

4. Pi Day Goes Global

  • Today, Pi Day is celebrated worldwide, with events taking place in universities, schools, research institutions, and even government buildings. 
  • Today, the day has become a platform for encouraging youth to seek jobs in math and science and for promoting STEM education.
  • Online communities and social media continue to play a vital role in spreading the pie-love, with puns, countless memes, and educational resources shared around the globe.
