Pi Day is an annual celebration of the mathematical constant π (pi). Pi Day is observed on March 14 (the 3rd month) since 3, 1, and 4 are the first three significant figures of π, and was first celebrated in the United States. [2][3] It was founded in 1988 by Larry Shaw, an employee of a science museum in San Francisco, the Exploratorium.

[215] [216] Pi Day in 2015 was particularly significant because the date and time 3/14/15 9:26:53 reflected many more digits of pi. [ 217 ] [ 218 ] In parts of the world where dates are commonly noted in day/month/year format, 22 July represents "Pi Approximation Day", as 22/7 = 3.142857.

Machin-like formula. In mathematics, Machin-like formulas are a popular technique for computing π (the ratio of the circumference to the diameter of a circle) to a large number of digits. They are generalizations of John Machin 's formula from 1706: which he used to compute π to 100 decimal places. [1][2] Machin-like formulas have the form.
The purpose of the proof is not primarily to convince its readers that 22 7 (or 3 1 7 ) is indeed bigger than π; systematic methods of computing the value of π exist. If one knows that π is approximately 3.14159, then it trivially follows that π < 22 7 , which is approximately 3.142857. But it takes much less work to ...
