We want to understand the subatomic phenomena, the nuclear force and the subatomic particles, the many different mesons. Gell-Mann has been very productive in bring order into this chaos, and we have by the collaboration of many people, now what is known as the Standard Model of Nuclear Interactions which comprises all the mesons, comprises the nucleon and its many excited states. And also the way nuclear matter behaves at enormously high energy, in which again my friend Gerry Brown is deeply involved, where you get the transition from normal matter, nucleons and mesons to something... the Quark Gluon Plasma. And as far as we can tell at this point, again the standard model seems to be correct, though experimenters have tried to disprove it, and so far they have not succeeded. But one can hope that maybe some new insight may be obtained by the higher energies which... which are available now at CERN, their Proton Accelerator which will get us into the trillion electron volt region and maybe new phenomena will then occur which will better elucidate the interaction of all the particles that we know, and elucidate that standard model.
