...last week the reflecting surface of Mount Wilson Observatory's 100-inch glass mirror, world's largest telescope reflector in use, was covered with a thin film of silver. If it were coated with aluminum, as all Mount Wilson astronomers have long wished, it would quickly acquire a protectively oxidized surface, it could be cleaned with ordinary soap and water and it would seldom if ever have to be removed from the telescope tube...
Last week Mount Wilson's big mirror got its first coat of aluminum, a film .00001 in. thick. The method of application was developed by Dr. John Donovan Strong and others from a plating process first hit upon by Thomas Edison. The glass disk is first thoroughly cleaned with blasts of electrons. It is then placed in a big sealed tank from which pumps suck almost all the air. Within the tank is a coil of tungsten wire covered with aluminum. When the wire is electrically heated the aluminum boils off as a vapor which, when it strikes...

...obvious from her output. The problem remained how to evaluate the bull's transmitting capacity. The Prentice group chose the method of systematically comparing the yield of bulls' daughters with the yield of their dams. In such wise Mr. Prentice's geneticist-in-chief arrived at Mount Hope's crowning achievement-the Mount Hope Bull Index...
First bull index published in any trade paper, the Mount Hope formula appeared in 1928. It was in two forms. The Commercial Form, for dairymen unwilling or unable to deal with fractions, simply placed the milk ability of the progeny halfway between the inheritances of the parents. Thus if the dam's production was 8,000 lb. and the daughter's 10,000, the bull's index was 12,000. The index was of course computed on the basis of as many dam-daughter comparisons as possible...
