ry. However, Gross and Wilczek recognized the natural candidate was the Yang-Mills theory that Greenberg and others had posited was neces- sary for Gell-Mann's quark hypothesis to explain the observed nature of elementary particles. In this theory each quark carries one of three 2P_Glealer-StoryEverTold_At

pointlike particles. Feynman then interpreted these objects as real particles, which he dubbed partons, and suggested they could be identified with Gell-Mann's quarks. This picture had a big problem, however. If all strongly interact- ing particles were composed of quarks, then quarks should surely be stro

ported to the physics community by Murray Gell-Mann at the 1960 Rochester meeting, as Gell-Mann had by then recruited Glashow to Caltech to work in Gell-Mann's group. Glashow's paper on the subject, submitted in 1960, appeared in 1961 in print. Yet, no sudden stampede occurred in response. After all, two
