Probing the Atom,) who gave us our first modern atomic theory. Despite his great contribution to science, Dalton was, oddly enough, not a highly skilled scientist; he was actually quite inept in the laboratory. But it is, after all, ideas that count—not how you arrive at them. He never married, perhaps because he ne

Particle Accelerators,tic particles from outer space, mostly protons, collided with the particles of our upper atmosphere. But we had no control over these collisions. And it soon became evident that if further progress was going to be made we would have to produce our own energetic particles. To do this we would need ac

Adding Color,were now understood. But searches were made for isolated quarks and none were found. Why? Perhaps they were forever confined to the interior of the hadrons as Gell-Mann had suggested. Many physicists were skeptical of the whole idea, yet the predictions of the theory were amazingly accurate. And the

Adding Charm,r. They occur in neutrino reactions. Most neutrino reactions involve “charged currents”; in these reactions the neutrino changes into an electron and in the process there is a transfer of charge. But according to the Weinberg-Salam theory there should also be cases where there is no transfer of char

Adding More Dimensions,were convinced that a way around the difficulties would eventually be found—a variation in which the problems would miraculously disappear. So far no such variation has appeared, but an important breakthrough has occurred. And most theorists believe that it is an important step in the right directio
