397 had been suggested by others two or three years before۔I felt that I was getting nearer to the present۔۔۔۔۔۔However Salam was skeptical۔He proposed another subject, and when I insisted on trying to classify the hadrons he said: "I wanted to assign you an easier problem, on the assumption that it would be better for you to produce a complete work during one year of leave from the army۔However, since your mind is made up, do it your way, but you should know that you are embarking on a highly speculative search۔If indeed you have already decided, at least do it properly۔Learn group theory thoroughly۔" So he recommended Dynkin book۔I learnt Dynkin's work and was now able to define what I was looking for: a rank two Lie group which would permit the classification of hadrons according to isospin and strangeness, in a manner that would fit the properties of the observed particles۔I found that only four groups might do the job, and began to examine each of these separately۔I remember that one of them (called (G2)) yielded diagrams in the shape of the Star of David, and I hoped that it might be the correct one- but it was not۔On the other hand SU (3) gave a perfect fit۔I finished my work in December 1960, and discussed it with Salam۔I then submitted a paper for publication early in 1961, and it appeared shortly after۔Excerpt from the book The Particle Hunters, by Yuval Neeman, Prof۔Emeritus, University of Texas, Austin, 1983,
