...that the experiment works", was the reply which Professor E. L. Chaffee G. '11, Associate Professor of Physics at the University, made to a CRIMSON reporter last night, when interviewed concerning the work which is being carried on by the United States Government to determine whether or not electrified sand scattered by airplanes will cause clouds and fog banks to disappear...
...Warren, he is not a Doctor, has no official relations with the University. Mr. Warren though of the original idea and came to ask Professor Chaffee's advice. The Government became interested in the proposition and undertook to finance it. Professor Chaffee then began research work to determine if sand particles could be electrically charged, and if so what was the most practicable method of obtaining this charge. All of these experiments were carried on by Professor Chaffee at the Cruft Laboratory at the University with the help of Mr. R. O. Chaffee '17. the two brothers invented a revolving...
...work is based on the assumption that visible forms of moisture in the air, such as mists, clouds, and fogs, are a form of colloidal suspension in gases and should be governed by the same general laws that prevail in colloidal action in liquids and solids. The sand tanks on the airplanes are flied with 120 mesh silica sand. When a cloud in found to have a negative charge positively charged particles are scattered at the extreme top; when the cloud has a positive charge negatively charged sand particles are scattered at the extreme top; and if the cloud...
...closing Professor Chaffee said that, although it might be possible to cause rain to fall by the use of the electrified sand, no real proof of this had as yet been obtained. He said it might be possible to produce rain in regions where large moisture clouds were present at fairly low altitudes, but that it would be absolutely impossible to produce rain under any other condition
...Severus. The city, 100 miles east of Tripoli, and about five miles from the sea at the present time, was formerly a seaport as the discovery of elaborate wharves proves. It was almost two miles square and the ruins are now buried in from 10 to 50 ft. of sand. A great palace, several statues and baths have been uncovered, and a series of columns nine metres high...
