## What is Pi Day?

Pi Day is an annual celebration of the mathematical constant pi (π), which is approximately 3.14159. It is observed on March 14th (3/14), which corresponds to the first three digits of pi. Pi Day was first celebrated in 1988 by physicist Larry Shaw and has since become a popular holiday among mathematicians, scientists, and math enthusiasts around the world.

Pi is a mathematical constant that represents the ratio of a circle’s circumference to its diameter. It is an irrational number, which means it cannot be expressed as a finite decimal or fraction. Pi has been studied for thousands of years and has many applications in mathematics, science, engineering, and technology.

Pi Day is often celebrated by eating pie, participating in math competitions or quizzes, attending pi-themed parties, and engaging in other activities that promote an appreciation for mathematics and its many applications.

## What is the History of Pi Day?

The history of Pi Day dates back to 1988 when physicist Larry Shaw organized the first Pi Day celebration at the San Francisco Exploratorium, a museum of science, art, and human perception. Shaw chose March 14th (3/14) as the date for the celebration to coincide with the first three digits of pi, 3.14.

The first Pi Day celebration at the Exploratorium included a circular parade, pi-themed exhibits, and the serving of actual pies. Since then, Pi Day has become an annual event, celebrated by math enthusiasts, students, and educators worldwide.

In 2009, the US House of Representatives passed a resolution recognizing March 14th as National Pi Day in the United States. The resolution encourages schools and educators to observe the day with appropriate activities and lessons about pi and mathematics.

Pi Day has also become a popular event on social media, with people sharing pi-related memes, jokes, and facts using the hashtag #PiDay.
