...years later that somebody else had had the idea before him, but had not pursued it.) Why not make use of some of the techniques of nuclear physics and inject into the patient a carefully measured dose of heavy water (D20, the oxide of deuterium, the nonradioactive isotope of hydrogen)? When the D20 and the body's ordinary water (H2O) were thoroughly mixed, the dilution of the heavy water would show the body's total water volume. All this was easier said than done; it took 2½ years to get results that satisfied Moore's meticulous...
Brookhaven-Syracuse University study last summer in Geneva. Last week experimental teams on opposite coasts of the U.S. confirmed its existence. They used two of the world's largest atom smashers, Brookhaven's Synchrotron and Berkeley's Bevatron, to fire negatively charged K mesons into a hydrogen bubble chamber. After the mesons collided with hydrogen nuclei, the scientists found two K mesons that were the decay products of an even more ephemeral particle. It has a life span of just 2/1 0,000th of a billionth of a billionth of a second-or just long enough...
...ultraviolet spectrometer, about the size and shape of a window box, will provide new information about the solar flares that erupt now and then from the sun's atmosphere, appearing as tongues of luminous gas flicking outward around sun spots. During a flare, clouds of ionized hydrogen gas--protons and electrons--shoot out, filling interplanetary space with intense radiation. When these clouds encounter the earth and pass through the earth's magnetic field into the polar regions, they produce the northern lights, and cause short-wave radio transmission to fade or black...
...science of radio astronomy, which has added to knowledge of the universe through radio telescopes tuned to various frequencies at the radio end of the electromagnetic spectrum. (The Harvard 60-foot radio telescope, for example, listens to 21-centimeter waves, the wavelength of emissions from neutral hydrogen gas. Hydrogen is the most abundant element in the universe...
Miss Arendt's realistic pessimism about the prospects for revolutions that will "constitute freedom" is the keystone of a world view which postulates the disappearance of war. She thinks that the destructive power of hydrogen bombs precludes their use in "rational" conflicts. When war has disappeared from the political landscape, revolution will remain as the only violent catalyst of social change...
