As Pi Day approaches, math enthusiasts join pizza and pie lovers to celebrate a surprisingly fun holiday. But what exactly makes this number so special?
Pi Day is celebrated every year on March 14 (3/14) because 3.14 represents the first three digits of the mathematical constant pi (π). Pi is the number used to represent the ratio of a circle’s circumference to its diameter, making it a fundamental part of geometry and mathematics.
The celebration was first organized in 1988 by physicist Larry Shaw at the Exploratorium science museum in San Francisco. Today, the day has grown so popular that it was officially recognized by Congress, turning a mathematical concept into a creative and interactive learning opportunity.
Fun fact: March 14, 1879 is also the birthday of Albert Einstein, one of the most influential physicists in history.
