...science scratches below the surface of the physical universe, it turns up more & more mysterious matters. A very small ghost, much smaller than an electron, now haunts modern physics. Its name, for want of something better, is the "neutrino." No one has ever seen a neutrino, or any trace which one has left behind it, but physicists are pretty certain that neutrinos are real. Just possibly, they may be the most important things in the physical universe...
...current issue of Physics Today, Dr. George Gamow tells why he thinks that neutrinos are as real as electrons or protons. Physicists, he says, invented neutrinos because they needed something to explain why electrons, shot out of the same atomic nuclei under the same conditions, do not all have the same energy. One way to account for this discrepancy is to imagine a very small, uncharged particle that departs at the same time as the electron, carrying with it some of the energy...
Neutrinos are perhaps two-thousandths the mass of an electron, and have no electric charge by which they can be influenced electrically. They pass right through matter as if it weren't there. Physicists have calculated, says Dr. Gamow, that it would take a lead shield 200 million million miles thick to stop speeding neutrinos...
...marbles. The atomic debris cascades toward the earth, some of the pieces with enough energy to crack atoms on their own. Occasionally one of these "extensive showers" covers an area 1,000 meters wide. The total energy in a shower runs up to 10 18 (one billion billion) electron-volts...
...result is an electric current which fluctuates rapidly to match the picture. This current is amplified and sent by a radio transmitter to the television receiver, where it controls the strength of a second electron beam in a rather similar tube...
