Google Doodle: What is Pi day?

On International Pi Day, Google creates formula using apple 'Pie'; watch how they did it

March 14 is quite a day!

Historically, the first Pi Day was held at a San Francisco Science Museum in 1988 when the physicist looked at the calendar and chose to pay homage to the mathematical entity.

Today's Google doodle pays homage to Pi Day by using an image of a salted caramel apple pie. If you were curious, the National Pi Day official website has expanded it to a million places. As to why a Google Doodle is celebrating the 30th anniversary of Pi, it is because the mathematical constant touches infinity in numerous ways.

Pi represents the ratio between a circle's circumference (perimeter) to its diameter (distance from side to side passing through the center), and is a fundamental element of many mathematical fields, most significantly Geometry.

Pi is a mathematical constant, meaning it isn't changed by the size of the numbers it's used to equate, and it is irrational, meaning it has an infinite number of digits that never repeat. The doodle has been created by award-winning pastry chef Dominique Ansel.

How Many Numbers Are in Pi?

Pi Day is celebrated every year March 14 as the first three digits of pi are three, one and four, representing the date. The ancient Babylonians calculated pi roughly 4,000 years ago. Pi is also celebrated by some on July 22 (22/7) instead of today and it's called Pi Approximation Day. The topics this year include calculations for Martian earthquakes, helium rain on Jupiter, and the rotation rate of the first interstellar visitor ever discovered, asteroid 'Oumuamua.
