Who invented pi( π )
Pi is the ratio of a circle’s circumference to its diameter in mathematics. The symbol was created in 1706 by British mathematician William Jones to symbolise the ratio, and it was later popularised by Swiss mathematician Leonhard Euler.
History behind the pi day
Pi Day is a day to honour the mathematical constant (pi), 3.141592653… Pi is the circumference to diameter ratio of a circle. The circumference of a circle is defined as its arc length, whereas the diameter is defined as the circle’s longest chord. Pi is a unique number since it is limitless and has no pattern. This indicates that the digits after the decimal point never repeat in a predictable way.
Physicist Larry Shaw founded Pi Day in 1988. Shaw worked at the San Francisco Exploratorium, where the inaugural Pi Day was held. It happened on March 14th (3/14), since the first digits of Pi are 3.14. On March 12, 2009, the United States House of Representatives declared March 14 to be National Pi Day.
For practical computations, ancient civilizations such as the Egyptians and Babylonians required reasonably accurate approximations of. Archimedes, a Greek mathematician, developed a technique to approximation with arbitrary precision in 250 BC. Chinese mathematics estimated to seven digits in the fifth century AD, whereas Indian mathematics approximated to five digits, both employing geometrical principles. The first computational formula for, based on infinite series, was developed a millennium later by the Kerala school of astronomy and mathematics, as reported in the Yuktibh, written around 1530
