Life of Pi: World’s most famous irrational number hailed (and explained) on Pi Day (VIDEOS)
Even those who have long blocked out all traces of Algebra classes from their minds probably still remember that Pi or π, equals 3.14, taken to two decimal places.
Pi Day has been trending on Twitter as people from all over the globe have been recognizing the mathematical constant’s special day.
Pi Day originated 28 years ago when physicist Larry Shaw introduced the initiative at the San Francisco Exploratorium.
The event became recognized officially in the US as National Pi Day in 2009, when the US House of Representatives passed a nonbinding resolution on the proposal. The move aimed to engage children in maths and science studies.
Today also marks legendary theoretical physicist Albert Einstein’s birthday, who recently had his theory of gravitational waves confirmed by scientists a century after he first suggested it.
This year, Pi Day is particularly special as 3.1416 is the most accurate approximation of pi to five decimal digits (rounded up).
