Collider Physics

Why is it interesting?

Is Mr. Lindley right? He concludes: "We are already at the point where experiments are becoming impossible for technological reasons and unthinkable for social and political reasons. An accelerator bigger than the supercollider would be a vast technical challenge. . . . Experiments to test fundamental physics are at the point of impossibility." Physicists, he says, seem to be returning to the days of the ancient Greeks, who did physics "by means of thought alone." Maybe he doesn't know about the Livingston curve. Mr. Lindley, I'm sure, would hate the Livingston curve. It's one of those mathematical curiosities that are probably meaningless. In the 1950's, a physicist named Stanley Livingston drew a line on a graph that plotted the energy available in laboratories from the time of J. J. Thomson (circa 1897) to his own era, then extended it into the future. He found a logarithmic relationship: the energy increased by roughly a factor of 10 every 10 years. The Livingston curve has accurately predicted accelerator energies in the 1960's, 70's, 80's and 90's. Extrapolated to the future, it predicts that we'll have what is called Planck-scale energy in the lab by the year 2150. A Planck-scale accelerator would be powerful enough to prove one of the most popular unified theories, superstring theory.

Explanations in this section should contain no formulas, but instead colloquial things like you would hear them during a coffee break or at a cocktail party.

Student

In this section things should be explained by analogy and with pictures and, if necessary, some formulas.
