...Caltech is dedicated to science and engineering, it is only natural that its laboratories should outnumber classrooms about five to one. And out of these laboratories have come some major revolutions in knowledge. The terms that Caltech has made important -cosmic ray, Badger's rule, alpha helix, Neurospora, positron, meson and mumeson-may not be exactly household words, but they have become standard parts of science's vocabulary...
...peculiar track was made by enormously powerful gamma rays that created electron-positron pairs as they streaked away from the site of the collision...
Normal matter is organized into tight little worlds-atoms-with positive protons in their nuclei and negative electrons revolving around them. There is also a homeless waif, the positron (positive electron), that seems to have no place in this orderly scheme. Born in atomic catastrophes, it lives only until it hits a normal electron. Then the two "annihilate" one another, turning into gamma rays...
...Energy Commission physicists, Frederick L. Reines and Clyde Cowan Jr., gathered an erudite task force at Los Alamos Scientific Laboratory and went hunting neutrinos. Theory told them that if a neutrino hits a proton, as may happen on very rare occasions, the reaction should yield a neutron and a positron (positive electron). If this happens in a liquid that scintillates in the proper manner, both particles will give flashes of light...
...physicists agree that negative protons are possible, but some like to speculate on the properties of reversed matter. It may turn into energy as soon as it encounters atoms of normal matter (when a positron hits an electron, they annihilate each other, leaving gamma rays as an X to mark the spot. All such possibilities, says Auger, are on "the frontiers of science." Only the 30 billion-volt cosmotron can test their reality...
