Simon Plouffe

Simon Plouffe (born June 11, 1956) is a 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] He was born in Saint-Jovite, Quebec.

He co-authored The Encyclopedia of Integer Sequences, made into the web site On-Line Encyclopedia of Integer Sequences dedicated to integer sequences later in 1995. In 1975, Plouffe broke the world record for memorizing digits of π by reciting 4096 digits, a record which stood until 1977.[4]

His "Inverter" web site contained 11.3 billion[5][failed verification] mathematical constants as of August 15, 2017.[6]
