...Physicist Murray Gell-Mann's theory, "The Eight-Fold Way." Gell-Mann lumped the known resonances together in orderly octets; their snowflake-like symmetries left slots for particles that were still unknown. But one octet seemed out of kilter. Unless, predicted Gell-Mann, a particle designated the phi-meson was found...

...Faculty of Sciences have exerted fully as power as the president; since resigned, internal affairs have on momentum he supplied. President Pusey and Edward S. Mason have at different times served as acting dean neither in any real sense "replaced" Bundy. In this "acting-only" capacity, for example, Meson was understandably hesitant about broad planning in educational policy--a field of obvious importance and a primary responsibility of the Dean of the Faculty...
...will ever see the little particle, but theoretical physicists-those mystic prophets of science-calculated several years ago that an unknown heavy meson probably can exist. Like the neutron, they figured, it would have no electric charge, so it would leave no track in a cloud or bubble chamber. They were sure it would disintegrate so quickly that other signs of its brief career would be hard to find. But the theoreticians considered the undiscovered particle so important that they named it omega in advance, implying that it might be the last unknown particle left in nature's locker...
