...farm he had tinkered with wires and electrical apparatus. At 27, he had designed the first open coil dynamo, following this with an arc lamp, the "ring clutch," in which the carbon is clutched by a ring attached to an armature which automatically keeps the light steady. This not only solved a long standing difficulty but brought the price to street level. Three years later (1879) the Public Square in Cleveland glowed under the first public arc lights...
Only in 1873, at Vienna, was it discovered that one electric dynamo could make another rotate. The second became a motor, and the electric transmission of power came within the possibilities of engineering. A Russian, Paul Jablochkov, invented the arc light in 1876; Thomas Edison the incandescent light in 1879. In 1881 Thomas Edison opened the first public electric supply station. And only five years later Tokyo, for more than two centuries secluded from European and U. S. science, also had its electric light system. The Tokyo Electric Light Co. was the innovation. It first served current for 75 lamps...
...have a look at Russia." Of course the news of his impending visit had elicited from Soviet Commissar of Education Anatoly Vasilievich Lunacharsky a formal invitation and an expression of enthusiasm that the Second Confucius was coming. Comrade Lunacharsky is a Red, but he knows his Deweys. A dynamo of energy, he not only directs the Commissariat (Ministry) for Education, but writes plays, is President of the Moscow Society of Dramatic Writers & Composers, and acts as supervising editor of three Moscow publications: Novy Mir (The New World), Krestyanka (The Peasant Woman), and Iskusstvo Trudyaschimsya (Art for the Workers). Lastly Comrade...
...dimes and quarters, squat. In turn, they use their quarters to try to flick their dimes into the ashtray in a graceful arc. It is a game requiring firm thumbs, keen eyes. It was invented by that skillful player, John Cowles, 29, who is to Des Moines what a dynamo is to a powerhouse...
...spot influence, Professor Stetson states, is that a sun-spot is nothing less than a gigantic solar cyclone, of the same nature as those which occur in the United States, but characterized by terrific electrical charges. These bodies are set in rotation during a storm, forming a veritable dynamo. The powerful magnetic field thus developed extends out into space and often disturbs radio, cable, and telegraph lines of the earth. Within recent years it has become possible to actually measure the field strength of these solar storms by means of a careful analysis of the spectrum of the sun spots...
