Pi !!!

Introduction:

Pi (π) is an irrational number and a Greek alphabet that represents the ratio of the circumference and diameter of a circle. It is a mathematical constant with an approximate value of 3.1416.

Pi is a very important constant in both mathematics and physics, and many formulas in these subjects are based on pi. As pi is an irrational number, its decimal representation never ends, and the digits are randomly distributed without following any pattern.Pi is a matter of curiosity for every mathematician and every person who loves math.

History:

The concept of pi is ancient, starting from the Babylonians who used pi to calculate the area of a circle with a value of 3. In 250 BC, popular Greek mathematician Archimedes invented an algorithm to find the value of pi. Chinese mathematicians found the value of pi to seven digits after the decimal point, while Welsh mathematician William Jones used the Greek letter π to represent the ratio of a circle's circumference and diameter for the first time in 1706. After the invention of calculus, people found the value of π to 100 digits after the decimal point, and with the invention of computers, the value of π has been calculated to many trillion digits after the decimal point. Currently, the unofficial record holder for reciting the digits of pi is Akira Haraguchi, who recited 100,000 digits after the decimal point.

Pi day:

Pi day is observed by mathematicians around the world on 14th March, which corresponds to the American date system's shortest approximate value of π as 3.14. For mathematicians, the word pi is a word of love, making pi day an important celebration for them.
