What’s more, Gell-Mann noticed a pattern in all particle interactions: The total strangeness number of all particles involved in any interaction is always conserved; that is, it’s the same before and after the interaction. Physicists liked this because it illustrated that a kind of symmetry was at work (which nature often displays—so these results seemed plausible). The conservation of the strangeness number in interactions could also be described in quantitative terms (which physicists always like—as quantitative terms are more readily verified than subjective observations).

The conservation of the strangeness number in interactions could also be described in quantitative terms (which physicists always like—as quantitative terms are more readily verified than subjective observations). Also, Gell-Mann’s observation could be used to explain the unexpectedly long life of the The Realm of Quarks 33 strange particles. Both Gell-Mann and the Nakano-Nishijima team published their ideas along these lines in 1953.
Lee and Yang crossed paths again for a time at the Institute for Advanced Study in Princeton, New Jersey, where Yang stayed to become professor of physics in 1955, while Lee accepted a position at Columbia University in 1953. For New Jerseyites, New York is always just a train ride away, and the two generally got together once a week to compare notes. The topic of conversation on that particular afternoon at the White Rose Café was the “strange particles” called K-mesons, which seemed to break down in two different ways—one, a sort of righthanded way, and the other, a sort of left-handed way.
