 | | The charm quark was discovered in 1974, for instance, before the evidence for the existence of quarks was really in hand -- before physicists were really convinced that experimentally we knew for sure there were quarks. |
 | | But from a physicist's point of view, I say that it's very likely that the vast underlying object is Nature, because of the fact that all these different classification schemes that have been, so far, brought into the "A-D-E" set-up, relate to physics: they're all important mathematical-physics objects. |
