Simon Plouffe

From Wikipedia, the free encyclopedia

Simon Plouffe is a Quebec mathematician born on June 11 1956 in St-Jovite. He discovered the formula for the BBP algorithm (the Bailey-Borwein-Plouffe formula) which permits the computation of the nth binary digit of π, in 1995. Plouffe is also the co-author of the Encyclopedia of Integer Sequences, made into the web site (On-Line Encyclopedia of Integer Sequences) dedicated to integer sequences later in 1995.

Plouffe discovered an algorithm for the computation of π in any base in 1996. Plouffe's Inverter is a web site that contains over 200 million mathematical constants. In 1975, Plouffe broke the world record for memorizing digits of Pi by reciting 4096 digits, which stood until 1977.
