Discover the date, history, meaning, importance and interesting facts of Pi Day 2022.
Any day that includes fun, learning, and pie is unforgettable. Pi is a Greek letter and a mathematical constant that expresses the ratio of a circle’s circumference to its diameter. Not only that, but it’s also Albert Einstein’s birthday that day, so it’s a mathematician’s dream come true.
PI DAY 2022: DATE
On National Pi Day, which falls on March 14 each year, mathematicians around the world commemorate the constant Pi.
For millennia, mathematicians had fun calculating the record numbers of Pi. These calculations were done by hand until the 1900s, and they hit record highs in the 500s.
PI DAY 2022: HISTORY
To understand Pi, you have to go back a few thousand years and study this enigmatic number. Archimedes of Syracuse, one of the greatest mathematicians of the ancient world, was the first to calculate the value of Pi.
However, William Oughtred originally gave it the Greek letter name in a book published in 1647, and it was later adopted by the scientific community when Leonhard Euler used the sign in 1737.
Math nerds around the world now commemorate this day. Pi Day has become a pop-cultural phenomenon, with people all over the world participating in events, pranks, sightings and eating as much pie as they can.
PI DAY 2022: MEANING
Pi, the ratio of the circumference of any circle to its diameter, is one of the oldest and best-known mathematical constants in the world.
It has a value of approximately 3.14159265. It is an irrational number, which means that it cannot be stated as a ratio of whole numbers and its decimal representation never stops or repeats.
