For Pi Day 2010, Google presented a Google Doodle celebrating the holiday, with the word Google laid over images of circles and pi symbols; [12] and for the 30th anniversary in 2018, it was a Dominique Ansel pie with the circumference divided by its diameter. [13] Some observed the entire month of March 2014 (3/14) as "Pi Month".
The number π (/ p aɪ / ⓘ; spelled out as "pi") is a mathematical constant, approximately equal to 3.14159, that is the ratio of a circle's circumference to its diameter. It appears in many formulae across mathematics and physics , and some of these formulae are commonly used for defining π , to avoid relying on the definition of the length ...
In 1988, physicist Larry Shaw decided this enigmatic number deserved its own holiday and started Pi Day, choosing March 14 to represent the first three digits of pi—and because it also happens ...
National Pi Day, the holiday that recognizes the mathematical constant that is π, is on Thursday, March 14. Also known as pi, the most commonly recognized digits are 3.14, which is why the ...
A History of Pi was originally published as A History of π in 1970 by Golem Press. This edition did not cover any approximations of π calculated after 1946. A second edition, printed in 1971, added material on the calculation of π by electronic computers, but still contained historical and mathematical errors, such as an incorrect proof that there exist infinitely many prime numbers.

Although rough estimates for pi were given in the Zhou Li (compiled in the 2nd century BC), [29] it was Zhang Heng who was the first to make a concerted effort at creating a more accurate formula for pi. Zhang Heng approximated pi as 730/232 (or approx 3.1466), although he used another formula of pi in finding a spherical volume, using the ...

William Jones, FRS (1675 – 1 July 1749 [1]) was a Welsh mathematician best known for his use of the symbol π (the Greek letter Pi) to represent the ratio of the circumference of a circle to its diameter. He was a close friend of Sir Isaac Newton and Sir Edmund Halley.
