Pi Day is celebrated every year on March 14 to honor the mathematical constant Pi (Ï€), which represents the ratio of a circle’s circumference to its diameter. The date 3/14 reflects the first three digits of Pi (3.14), making it a special day for mathematicians, students, and science enthusiasts around the world.
What is Pi?
Pi is an irrational number, meaning its decimal representation goes on forever without repeating. It is widely used in mathematics, engineering, physics, and many scientific calculations involving circles and curved shapes.
The value of Pi begins with 3.14159, but it continues infinitely with no repeating pattern.
History of Pi Day
Pi Day was first celebrated in 1988 by physicist Larry Shaw at the Exploratorium. Over time, the celebration gained popularity among schools and science communities.
In 2009, the United States Congress officially recognized March 14 as National Pi Day in the United States.
