...Anderson's 50,000,000-volt rays prove him right, reasoned Dr. Millikan last week. He figures that at the interstellar birth of a helium atom 70,000,000 volts would be released; for oxygen 116,000,000 volts; for silicon 216,000,000 volts; for iron 450,000,000. Those are, he is convinced, the only elements floating between the stars in sufficient quantities to produce radiation effective on earth. Radiations from helium, oxygen and silicon do not reach the earth because the atmosphere damps them. It is iron's radiation which Dr. Millikan believes his adherents and opponents...
...flask of pyrex glass of 22-litre capacity, with a stem two metres long and 70 millimetres in diameter. He pumped out the air and moisture, filled the flask with nitrogen gas, sealed it. Around the stem he wrapped a wire, touched the wire to a 25,000-volt high-frequency generator. There was a flash, then the bulb began to glow with a bright yellow light. It continued to glow for 35 minutes after the shock had been administered. Four months later, Professor Knipp repeated the procedure. For no reason that he could see the bulb remained bright...
...transmutation are the alpha particles of electricity which unstable atoms emit and which unsettle other atoms upon collision. Radium emits alpha particles naturally (also betas and .gammas, the latter helpful in cancer). Artificial streams of alpha particles have been produced from vacuum tubes carrying as high as 650,000 volts. But the production of such voltages is expensive. 'The significance of Dr. Van de Graaff's purchase at the 5f/ & 10^ store ribbon counter was that he had discovered how to produce a current of electricity with light-ning-like force at a cost (for a small...
...Graaff demonstrated his machine last week in a dark laboratory at Princeton, a soft crackling sound was heard, electricity "spilling" from the copper balls in a "corona" effect. Before spilling, each ball had stored 750,000 volts from the whizzing ribbons. The hair of everyone in the room slowly rose and stood on end in the galvanized atmosphere. Then came a sharp report and the spectators' hair fell back into place as a bright i.500,000-volt shaft of lightning shot from one ball to the other, the overflowing positive and negative charges rushing together. Significance was that this...
...Graaff turned up the lights and smiled into a circle of marveling faces. A few nights later he was to demonstrate his $90 lightning to the American Institute of Physics in Manhattan. After that he was to build a bigger, 10,000,000-volt model of his ribbon-&-copperball generator at M. I. T. He believes 50,000,000 volts may be possible...
