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.
As mathematicians discovered new algorithms, and computers became available, the number of known decimal digits of π increased dramatically. The vertical scale is logarithmic . For most numerical calculations involving π , a handful of digits provide sufficient precision.
Simon Plouffe (born June 11, 1956) is a French Canadian mathematician who discovered the Bailey–Borwein–Plouffe formula (BBP algorithm) which permits the computation of the nth binary digit of π, in 1995. [1] [2] [3] His other 2022 formula allows extracting the nth digit of π in decimal. [4] He was born in Saint-Jovite, Quebec.
Calculation made in Philadelphia, Pennsylvania, giving the value of pi to 154 digits, 152 of which were correct. First discovered by F. X. von Zach in a library in Oxford, England in the 1780s, and reported to Jean-Étienne Montucla, who published an account of it.

William Shanks (25 January 1812 – June 1882) [1] was an English amateur mathematician. He is famous for his calculation of π to 707 places in 1873, which was correct up to the first 527 places. [ 2 ]
Carl Louis Ferdinand von Lindemann (12 April 1852 – 6 March 1939) was a German mathematician, noted for his proof, published in 1882, that π (pi) is a transcendental number, meaning it is not a root of any polynomial with rational coefficients.
Like many great mathematical conundrums, Ramsey problems are easy to understand but devilishly difficult to solve.However, after 90 years left unsolved, mathematicians from the University of ...
Zu Chongzhi, along with his son Zu Gengzhi, wrote a mathematical text entitled Zhui Shu (綴述; "Methods for Interpolation"). It is said that the treatise contained formulas for the volume of a sphere, cubic equations and an accurate value of pi. [5] This book has been lost since the Song dynasty. His mathematical achievements included
