Example text

The top quark, for example, still was not experimentally confirmed as of mid-1994. No one had yet found the tau neutrino, either. Do neutrinos have a rest mass? No one had been able to tell. Other inconsistencies have also required some patchwork (always a bad sign for a theory or model). Secondly, this model is extremely complicated—usually another bad sign. Physicists tend to think that simplicity, not complexity, is the rule, and wherever they have explored this idea thoroughly, nature has proven to prefer simplicity.

These names are merely figurative; quarks don't literally have color as we know it. But when quarks combine in groups of three, they always combine one each: red, blue and green. It's just a way to talk in threes. The red, blue and green cancel each other out to produce colorlessness (as the three primary colors do on a color wheel when you spin it). 32 Of course, quarks also combine in pairs to form mesons, and in that case, for example, a red quark will combine with an antired quark. The red and antired cancel each other out and you get a colorless result.

21 C H A P T E R 2 THE REALM OF QUARKS athways through the chaotic subatomic particle jungle have not been easy to find. But to one multitalented physicist goes much of the credit for blazing those pathways—ingeniously sensing the topography and insightfully mapping it out, while marking the complicated trail with whimsical names and literary allusions. Murray Gell-Mann, whose father had left Austria to settle in New York, was born in New York City in 1929. He entered Yale University on his 15th birthday, and that fact alone tells a lot.
