What is Pi (π)?

Let us divide the circumference of a circle by its diameter. The answer will always be 3.14, a number that represents the Greek letter π. The result of the calculation literally has no other pattern and can go on like this forever. 

History of Pi Day

It was in 1988 that people celebrated the earliest official celebration of Pi Day. This celebration was organized at the San Francisco Exploratorium, by physicist Larry Shaw. The people, joined by the other staff of the Exploratorium, marched around the structure while eating pies made of fruit. As of today, the Exploratorium still celebrates Pi Day in the same manner. 

Later on, in March 2009, the House of Representatives in the United States of America passed a resolution that recognized March 14th as Pi Day. Moreover, in 2010, on this day, Google celebrated this day by showing a Google Doodle, with the word “Google” lying over images of circles and Pi symbols. 

Pi Day Observations

People observe Pi Day in many different ways. Some eat pie of various different flavors on this day. Yet there are others who play with pies and throw them at each other and discuss the significance of the number 3.14 and the Greek letter π. This is because the words “pi” and “pie” are homophones and have a lot of puns based on them. Many schools across the United States also hold competitions related to Pi.
