...electrons and were multiplied by a billion and again by a billion, all those electrons would weigh just about one ounce avoirdupois. And yet one of those almost weightless electrons, a negative charge of electricity, as it shoots from the cathode of an X-ray tube or from the filament of a radio tube engraves its path on metal...
...joined three of his vacuum tubes in tandem and in the connecting necks placed hollow metal cylinders. From a tungsten filament cathode in the first tube, 300,000 volts of electricity shot cathode rays into the first metal cylinder, which functioned as anode to the first and cathode to the second. There 300,000 more volts kicked the speeding electrons into the next similarly acting cylinder, where 300,000 more volts gave a final kick. The rays cascaded out of the apparatus at 175,000 miles per second-almost as fast as light, 350,000 times faster than a rifle...
Last week, Professor Karl T. Compton reported that he had put molecular hydrogen into a tungsten tube, heated it to 2,800 degrees Centigrade, thereby dissociating it into atomic hydrogen, and shot into this a current of electrons from a hot filament similar to those used in a radio tube. The energy of this current was readily reckoned in volts, and as the voltage was increased things began to happen to the hydrogen atoms it encountered. Suddenly they began to emit radiation of a definite wavelength, measurable as a single line in a light spectrum. The hydrogen atoms had been...
There lay the significance of an announcement last week by Physicist Ralph C. Hartsough of Columbia that he had perfected a set of mirror-scales capable of weighing, distinctly and faithfully, down to one 280-billionth of an ounce. Gossamer quartz filaments balance the scales, the slightest titillation of which is reflected from their gold-mirrored surfaces by a ray of light. The ray is split by two half-mirrors, being reunited on the scale-mirrors, where any disparity between the wavelengths of the reunited portions is clearly seen as shadow bands. Thus, when the object weighed (1/29...
...country and England. "If the United States and Great Britain cannot live together in peace and harmony", he declared, "what chance is there for the rest of the world. These nations should go side by side through the years with one mind and thought. In such a full filament lies the future hope of the human race...
