For 10 points, identify this physicist who developed the Eightfold Way and the quark model.
Like Sudarshan and Marshak, and with Feynman, this man posited a vector-minus axial Lagrangian for weak interactions. This man classified kaons and hyperons by positing the idea of strangeness, and charge is equal to one-half the hypercharge plus the isospin in a formula named for him and a Japanese physicist.  One system developed by this man was vindicated by the discovery of the omega-minus baryon. That idea arranged the spin-3/2 baryons into a decuplet and the spin-1/2 baryons into an octet, from whence it got its Buddhist-sounding name. That theory led to the idea that nucleons were composed of a triplet of strongly-bound color-charged particles.
