The iconic number Pi has its own holiday, Pi Day. Fans around the world celebrate him with pi contests, poetry and even pi music. Physicist Larry Shaw launched Pi-Day in 1987 at the Exploratorium in San Francisco, the world’s first museum of applied science. His fascination with all kinds of rotations gave rise to the idea of ​​celebrating Pi Day with special events such as circling a sign with the first hundred digits of Pi and reading it aloud.

3.14 times the diameter is the circumference of the circle

The number pi has fascinated people since ancient times. The Greek physicist Archimedes (287-212 BC) calculated it to two decimal places. 3.14, like 3/14, with the US spelling of March 14. Therefore, this date is considered Pi Day.

An Indian knows the 70,000 digits of Pi by heart

The circular number pi is fascinating because the numbers after the comma are not repeated regularly. This is how Pi-Sport evolved: Who can remember the most numbers? Rajveer Meena entered the Guinness Book of Records on March 21, 2015, ten hours later. The Indian knows the 70,000 digits of the district number by heart.

22.4 bill decimal places are now calculated

While he knew only 100,000 decimal places in 1961, on November 11, 2016, Swiss Peter Trüb broke the current trillionth record on a computer. To verify this number, the software needs 105 days of computing time.

Exciting facts about the PI number

The combination of numbers is used to calculate the circumference of a circle, so pi is also called the “circular number”.

Pi was first described by Archimedes.

Swiss mathematician Leonard Euler popularized the number again in the 18th century. Euler was the first to use the Greek numeral π for the number. π means circle in the Greek alphabet.

Pi is an infinite number. The world record for calculating pi is five trillion digits after the decimal point.

Since pi is infinite, the “true” circumference is never calculated, only the approximate circumference.

In America, March 14 is written as 3.14, so the number of circles is celebrated on this day. Because pi and “pie” are pronounced the same, people eat round cakes on “Pie Day.”

On the first Pi Day (1988) there was only a small party among colleagues but even then there was cake. For the 30th anniversary of Pi Day (2018), Google commissioned pastry chef Dominique Ansel to pay homage to Pi from the dough. This can be found on Doodle’s website.
