National Numbers Hall of Fame

The National Museum of Mathematics is pleased to announce the new National Numbers Hall of Fame!

MoMath’s National Numbers Hall of Fame aims to recognize numbers for their truly outstanding contributions to society — from their roles in groundbreaking mathematical research and applications, to their influences on mathematical recreation and the public perception and dissemination of mathematics.

Numbers will be recognized for their ubiquity in mathematical formulae; popularity in society over sustained periods; and ability to inspire people to play, experiment, and smile.

Each year, the Hall of Fame will induct three new honorees, showcasing numbers that have radically transformed the world in which we live, or have simply charmed us with their remarkable properties and inspired us to step back and think.


Any number that has exhibited at least one of the following five attributes will be eligible:

  1. Profound influence on mathematical research
  2. Profound influence on recreational mathematics
  3. Sustained popularity in the public discourse
  4. Role in important mathematical formulae
  5. Remarkable, thought-provoking characteristics that inspire play and creative thought

Only those numbers whose value can be explained clearly to a general audience of non-specialists will be considered for inclusion.

National Number Hall of Fame — Nomination and Selection Process

The public is invited to nominate numbers online through the National Numbers Hall of Fame website,, through June 30, 2021.  Each year, an international team of experts who exemplify creativity and commitment to the field, including mathematicians, math educators, and those who specialize in mathematical outreach, will review the submitted nominations and select 12 numbers that best meet the criteria for selection to be designated as finalists.  Final selections will be made by an internal Museum advisory committee.

The inaugural class of three numbers will be inducted in September 2021.

Nominate a number by June 30
