National Pi Day is here, offering a chance to celebrate both a mathematical constant and, for many, a delicious slice of pie – or pizza!
What is pi?
Observed on March 14 (referencing 3.14), Pi Day commemorates the mathematical constant π, which represents the ratio of a circle’s circumference to its diameter. According to Guinness World Records, the most accurate value of Pi calculated to date is more than 62 trillion digits – 62,831,853,071,796 – as of August 2021, determined by the University of Applied Sciences in Switzerland.
Beyond the mathematical significance, Pi Day has become a popular occasion for businesses to offer deals on pies and pizzas.
