# Simon Plouffe

Simon Plouffe is a Quebec mathematician born on June 11, 1956 in Saint-Jovite, Quebec. 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.

In 1975, Plouffe broke the world record for memorizing digits of Pi by reciting 4096 digits, which stood until 1977.

Plouffe discovered an algorithm for the computation of π in any base in 1996. He has expressed regret for having shared credit for his discovery of this formula with Bailey and Borwein.[1]

Plouffe's Inverter is a web site that contains 3932000000 mathematical constants as of August 3, 2010.
