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 π
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.

Mathematical constant
A mathematical constant is a special number, usually a real number, that is "significantly interesting in some way". Constants arise in many different areas of mathematics, with constants such as and occurring in such diverse contexts as geometry, number theory and calculus.What it means for a...
