On Thursday, March 14th, math enthusiasts of all ages and occupations, ranging from college students to rocket scientists, observe Pi Day. This date, written as 3/14, represents the first three digits of Pi, an infinitely long number with numerous practical applications.

Many individuals worldwide will celebrate this day by enjoying a slice of pie – whether it be a sweet, savory, or even pizza variety.

Pi is a fundamental numerical value that represents the proportion between a circle’s circumference and its diameter. This mathematical constant has been incorporated into numerous equations in fields such as physics, astronomy, and engineering, with its origins dating back thousands of years to ancient civilizations like Egypt, Babylon, and China.

The origin of Pi Day can be traced back to 1988, when physicist Larry Shaw initiated festivities at the Exploratorium science museum in San Francisco. However, it wasn’t until twenty years later that the holiday gained widespread recognition. In 2009, Congress officially declared March 14 as the designated day, with the intention of promoting greater interest in math and science. Interestingly, this date also happens to be Albert Einstein’s birthday.

Additional information about the origins of the holiday and its current celebrations can be found below.

The value of pi, represented as 3.14, can be used to determine the circumference of a circle by multiplying it by the diameter (the distance across the middle of the circle).

Pi is a constant and infinite number, making it mathematically irrational. Prior to the digital age, figures like Isaac Newton manually calculated decimal points for many hours. Today’s advanced technology has allowed for trillions of digits of pi to be computed, yet there is no finite end.

The term was not bestowed upon it until 1706, when it was utilized by Welsh mathematician William Jones as the Greek symbol representing the numerical value.

What’s the significance of that particular letter? It’s the initial letter of the Greek words “periphery” and “perimeter,” and pi represents the relationship between a circle’s perimeter (or circumference) and its diameter.

The numerical value is crucial in precisely aligning an antenna towards a satellite. It aids in determining various measurements, such as the required diameter of a large cylinder for refinery machinery or the dimensions of paper rolls for printers.

The value of pi can help calculate the appropriate size for a tank used in heating and air conditioning systems for buildings of different dimensions.

Pi is a fundamental tool for NASA in their daily operations. It plays a crucial role in calculating orbits, determining the positions of planets and other celestial bodies, and is utilized in various aspects of rocket propulsion, spacecraft communication, and even the proper deployment of parachutes during splashdown on Earth or landing on Mars.

By utilizing a limited sequence of pi, experts state that it is capable of determining the exact measurement of the Earth’s circumference with a margin of error of only 0.6 centimeters per 25,000 miles (40,000 kilometers).

Each year, the museum in San Francisco that created the holiday plans various activities such as a parade around the round plaque known as the Pi Shrine, with a circumference of 3.14, and celebratory events featuring plenty of pie.

Various events are now being held on college campuses throughout the country. An instance of this is Nova Southeastern University in Florida, which will be hosting a range of activities such as “Mental Math Bingo” and also offering free pizza during the event, with traditional pie for dessert.

Jason Gershman, the chair of NSU’s math department, stated that Pi Day is an occasion to commemorate math, enjoy ourselves, and acknowledge its significance in our daily lives.

According to Stephen Jarrett, the manager of Michele’s Pies in Norwalk, Connecticut, it is one of their busiest days of the year.

In an interview, Jarrett stated that on Thursday, we will be sending out numerous pie orders to businesses, schools, and individuals. Pi Day is an enjoyable and playful holiday centered around a beloved mathematical number. It’s a chance for people to turn something ordinary into something delightful and tasty. People often indulge in sweet and savory pies to celebrate Pi Day, making it a perfect excuse for a little treat.

Every year, NASA hosts the “Pi Day Challenge” on the internet which features a variety of games and puzzles. Some of these activities are taken from NASA’s own folder, such as determining the orbit of an asteroid or the daily distance a moon rover must travel to survey a specific area on the moon.

Einstein, a renowned scientist, was born on March 14, 1879 in Germany. He utilized the infinite number Pi in several pivotal theories and now, Pi Day serves as an additional occasion to commemorate his accomplishments.

On March 14, 2018, at the age of 76, renowned physicist Stephen Hawking passed away, creating a mathematical symmetry. Despite this, Pi remains an imperfect number. Hawking famously expressed this idea.

The fundamental principle of the universe is that there is no such thing as perfection. It is simply an unattainable concept. If everything was flawless, neither of us would be able to exist.
