Since the late 1960s, the views the nucleons and mesons might be complex system of more fundamental point-like particles had gained momentum. Available at http://www.edge.org/conversation/the-making-of-a-physicist (retrieved December 1 2013)

Starting from 1960, Gell-Mann realized that the last question was the fundamental one and found a promising response. Was it possible to find a deeper symmetry of strongly interacting particles that included isospin and hypercharge (then defined as the sum Y=B+S), and which could unify strange and non-strange particles?

The particles that had S different from zero were later called “strange” particles. 2). Simultaneously with, and independently from, Israeli theoretical physicist Yuval Ne’eman, Gell-Mann developed the view that strongly interacting particles might be classified by extending the isospin group SU(2) to an approximate SU(3) symmetry.

In 1961 and 1962, Gell-Mann published the two papers “The Eightfold Way: A Theory of Strong Interaction Symmetry”, and “Symmetries of Baryons and Mesons”, which contain the theoretical framework for the classification of strongly interacting particles, including the “Gell-Mann matrices” of the infinitesimal generators of the group SU(3) and a formula that accounted for the difference of mass among baryons as well as among mesons.

There, the Physics Department counted on several prestigious members as well as bright postdocs and graduate students. “For his theory for critical phenomena in connection with phase transitions,” Wilson was awarded the 1982 Nobel Prize in Physics.

In 1956, following the discovery that parity was violated in weak interactions, Gell-Mann and R.

Feynman developed the V-A theory of weak interactions, simultaneously proposed by Robert Marshak and George Sudarshan. Everyone who can is playing the Common Knowledge Game as a Missionary. Gell-Mann stayed at the Institute one year. Gell-Mann began collaborating with Marvin “Murph” Goldberger on the quantum field theory of the pion-nucleon interaction. Gell-Mann christened this classification the “eightfold way,” as an ironical reference to the Eightfold Path of Buddhism.

In this period, he developed insights in the application of novel theoretical tools - such as the Feynman diagrams - and directed his attention to the most problematic theoretical issues. (I refer to it by this name because I once discussed it with Murray Gell-Mann, and by dropping a famous name I imply greater importance to myself, and to the effect, than it would otherwise have.)

Briefly stated, the Gell-Mann Amnesia effect is as follows.


The situation completely changed at the end of the 1960s, when observations of the inelastic scattering of electrons on protons as well as of neutrinos on nucleons suggested that nucleons were made of point-like constituents. These observations soon sparked many questions: Which was the difference between short-lived resonances and the group of already known strongly interacting particles formed by pions, nucleons, and strange particles?

He has been bringing many of these topics together by furthering the study of complex adaptive systems. Crichton pretty much invented the techno-thriller genre of books and film, starting with The Andromeda Strain, which is one of the most influential books in my life, for sure.
