One of the biggest examples of the power of symmetry is the derivation of the quark model, by Murray Gell-Mann, which used two observed properties of seemingly unrelated composite particles to be brought into an organized relationship with each other. After probing the particles making up the Nucleus of particles, they stumbled upon Pions, Kaons, Sigma Particles, and more. Gell-Man brought order to this particle rumpus, and then pushed it one step further, as it began to dawn on scientists that these particles themselves were not the last level of structures to be observed, leading him to predict an entirely new class of particles, called quarks. He too, was swayed by beauty, saying that "...a beautiful or elegant theory is more likely to be right than a theory that is inelegant."

Part of the belief for beauty is that, the beautiful things that have been discovered, are the only way for things to be- such as the one to relationship of quark's and lepton's.

The big win of symmetry, was in deriving the quark model - particle collisions revealed a large number of smaller particles, which seemed to have no relation to each other.
