losely surround the negative charge, and so at a distance the physical effects of the initial negative charge are reduced. This meant, according to Landau, that the closer you get to an elec- tron, the larger its actual charge will appear. If we measure the electron charge to be some specific value at

s would leave only the photon left over as a massless gauge boson. But there's more. By virtue of the gauge symmetry he introduced, Weinberg's new Higgs particle would also interact with electrons, and when the condensate formed, the effect would be to give electrons a mass as well as the W and Z pa

a revolutionary. But reluctant revolutionary he was, although, due to some shortsighted journal editors, he almost didn't get the chance. In 1960 Higgs had just taken up his post and had been asked to serve on the committee that coordinated the first Scottish Universities Summer School in Physics.
