Quotes edit

  • If there is no connection between quarks and leptons, since quarks make up the proton, then the balance of the proton and electron charge is just a remarkable coincidence. It seems impossible for any thinking person to be satisfied with coincidence as an explanation. Some principle must relate the charges of the quarks and the leptons. What is it? A fancier way of saying it, and more or less equivalent, is that for the electroweak theory to make sense up to arbitrarily high energies, the symmetries on which it is based must survive quantum corrections.
  • Each second, some 1014 neutrinos made in the Sun and about a thousand neutrinos made by cosmic rays in Earth's atmosphere pass through your body.
  • Neither quarks nor leptons exhibit any structure on a scale of about 10-16 cm, the currently attained resolution. We thus have no experimental reason but tradition to suspect that they are not the ultimate elementary particles. Accordingly, we idealize the quarks and leptons as pointlike particles, remembering that elementarity is subject to experimental test.
