Pi Day 2022: Date, history and significance

Any day that includes fun, learning, and pie is one to remember. 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 on this day, so it's a mathematician's dream come true.

On National Pi Day, which falls on March 14 every year, mathematicians all across the world commemorate the constant Pi.

PI DAY 2022: DATE

For millennia, mathematicians have enjoyed calculating Pi's record digits. These calculations were done by hand until the 1900s, and they reached records in the 500s.

PI DAY 2022: HISTORY

To understand Pi, we must travel 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 compute the value of Pi.

However, it was initially given the name Greek letter by William Oughtred in a book published in 1647 and it was later adopted by the scientific community when Leonhard Euler used the sign in 1737.

Pi, the ratio of any circle's circumference to its diameter, is one of the world's oldest and most well-known mathematical constants.

It has a value of about 3.14159265. It is an irrational number, meaning that it cannot be stated as a ratio of whole numbers and that its decimal representation never stops or repeats.
