...three years ago 58 solar elements had thus been recognized. Then Dr. Charlotte Emma Moore, 38-year-old Princeton astronomer, was able with the help of two colleagues to announce phosphorus...
Results of this experiment are extremely interesting to the observer. Rubber loses its elasticity and becomes a translucent, horny material; paper is similarly affected. Red phosphorus is turned permanently black. The electrical resistance of some metals was found to be abnormally high under this treatment...
...California's Lawrence and Italy's Fermi. Dr. Lawrence obtained 5,000,000-volt gamma rays from salt, evoked the possibility of injecting harmless but radioactivated salt compounds into the human body as a cancer remedy. Dr. Fermi has coaxed radiations of beta particles (fast electrons) from phosphorus, iron, silicon, aluminum, chlorine, vanadium. copper, arsenic, silver, tellurium, iodine, a dozen others...
...ordinary exhibitions, a sabre match in the dark with phosphorus-treated hilts; and an epee match, in which the two contestants had balloons attached to their ankles and throats, added to the interest...
...radio-silicon. They foresaw the use in cancer therapy of packets of artificial radio-elements, which, because they disintegrate as the radiation dwindles, would not have to be withdrawn from the body after treatment as radium seeds must be. They told of experiments presaging the production of a radio-phosphorus which would emit neutrons (emitted by no natural radioactive substance). And they spoke of work indicating the existence of the neutrino, an ultimate particle lacking electrical charge like the neutron, but small in mass like the electron. Many a physicist has held the neutrino's existence called...
