...William LeRoy Emmet of the General Electric Co. told of the development of the mercury vapor turbine, explaining that he believed it would prove 40% more efficient than the steam turbine...
Professor Miethe's reported discovery that quicksilver could be transformed into gold, an apparent solution of an age-old problem and a realization of the dream of ancient alchemists, was an accident, as were many other scientific discoveries. Using a quartz lamp and quicksilver vapor, he was endeavoring to determine the effect of ultra violet rays upon certain materials. An electric current of 170 volts and of a comparatively low amperage was passed through the lamp...
Some months ago, Prof. Adolf Miethe of the Charlottenburg Technical College, Berlin, was experimenting to determine the effect of violet electric rays upon mercury vapor. Using a quartz lamp, a current of about 170 volts and a low amperage and about half an ounce of mercury vapor, he was surprised to find, after about 200 hours of operation, that the mechanism was out of order. He opened the lamp and found that the inside was coated with a thin, black film. Scraping off some of the film, he analysed it and discovered it to be gold. The experiment was repeated...
...Bovie G. '13, professor of biophysics at the Medical School, acting in conjunction with President C. C. Little '10 of the University of Maine, demonstrated yesterday at the University of Maine laboratories that ultraviolet rays obtained by the use of a fused quartz mercury vapor arc lamp are beneficial to health. These two scientists have been conducting a series of experiments with chickens, and their findings reveal important medical properties of this light...
...There's really nothing much to it," he added. "I intend merely to weigh the water vapor which is present in every breath we exhale. It's the same vapor that we see on a cold...
