March 14 is Pi Day, an annual celebration of the mathematical constant of pi, representing the ratio of a circles circumference to its diameter.
The holiday is observed on March 14 or 3/14 because 3.14 are the first three digits of the infinite number pi â 3.14159 … and on and on.
The celebration of Pi Day was the brainchild of physicist Larry Shaw and was first observed in 1988 at San Franciscos Exploratorium, a science museum, and has since grown into an international event.
At that first simple salute to pi in 1988, Shaw and his wife, Catherine, took â guess what? â pies â and tea to the museum for the celebration of the infinite number. Shaw became known as the Prince of Pi and reigned over the museums annual honoring of the never-ending number for years, until his death in 2017.
Pi Day festivities grew to include the honoring of mathematical genius Albert Einstein because he was born on March 14.
The U.S. House of Representatives officially designated March 14 as National Pi Day in 2009.
The Exploratorium posted on its website that this years observance of pi would include the annual Pi Procession, which the museum described as being executed by a high spirited crowd through the museum and would circle the museums Pi Shrine 3.14 times, while waving the digits of pi and dancing along to a brass band.
And, of course, all participants in the revelry would be rewarded with a free slice of pie.
Pi Day is now celebrated around the world by pi lovers and is viewed as a way to arouse interest in the sciences among young people.
Pi lovers had a special treat in 2015, History.com reports. That year Pi Day was celebrated on 3/14/15 at 9:26:53 a.m. The combined numbers of the date and time represent the first 10 digits of pi â 3.141592653.
