What is Pi Day? Why is it celebrated?

 Pi Day is an annual celebration that takes place on March 14th (3/14) to commemorate the mathematical constant pi (π). Pi is a mathematical constant that represents the ratio of a circle's circumference to its diameter, which is approximately 3.14159. Pi is an irrational number, which means that it has an infinite number of decimal places, and its digits never repeat.

Pi Day is celebrated by mathematicians, scientists, and math enthusiasts all around the world. The day is marked with various activities, such as reciting the digits of pi, hosting math-related competitions, enjoying pies, and participating in other events that celebrate math and pi.

Pi Day is celebrated on March 14th because the first three digits of pi are 3, 1, and 4, which correspond to the date. The celebration of Pi Day was first organized by Larry Shaw, a physicist at the San Francisco Exploratorium, in 1988. Since then, Pi Day has become an international event and is celebrated by millions of people each year.
