Gell-Mann's work in the [[1950s]] involved the understanding of a class of then newly discovered [[elementary particles]] which came to be called [[kaon]]s and [[hyperon]]s. Classifying these particles led to the idea of a new [[quantum number]] called [[strangeness]]. One of Gell-Mann's triumphs is the [[Gell-Mann–Nishijima formula]], which was, initially, a formula from empirical results, but was later explained by the quark model. Gell-Mann and [[Abraham Pais]] were involved in explaining many puzzling aspects of the physics of these particles.
In [[1961.]], this led him (and [[Kazuhiko Nishijima]]) to introduce a classification of elementary particles called [[hadron]]s (also independently proposed by [[Yuval Ne'eman]] at around the same time). This scheme is now explained by the [[quark model]]. Gell-Mann's own name for the classification scheme was the ''[[Eightfold way (physics)|eightfold way]]'', because of the ''octets'' of particles in the classification, and also after the [[Noble Eightfold Path|eightfold way of Buddhism]] — a choice that is reflective of Gell-Mann's interests.{{Fact|date=February 2007}}
Gell-Mann, and, independently, [[George Zweig]], then went on, in 1964, to postulate the quark model. This introduced [[quark]]s, the particles of which the [[hadron]]s were composed, a name coined by Gell-Mann through a reference to the book ''[[Finnegans Wake]]'', written by [[James Joyce]] ("Three quarks for Muster Mark!" - book 2, episode 4). Zweig had referred to the particles as "aces" but Gell-Mann's name caught on.
