Reduced to simplest terms, the machine has ten "integrators," each of which is set by a hand dial to compute the effect of a variable quantity on the problem to be solved. Each dial sets two movable parts -an 8-in. stainless steel disk, mirror-smooth, and a smaller wheel with a knife edge in contact with the disk. Governed by precisely controlled friction, the speed of the small wheel is the crucial factor in solving any problem. A bevel gearing delivers that factor to the "answer table" where the factors from all the integrators are combined and the final...

...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...
Titian's Toilet of Venus came from the Hermitage Museum, too, and cost Mr. Mellon $544,320. Painted about 1565, showing a half-nude, buxom Venetian blonde gazing into a mirror supported by cupids, it is supposed to be a portrait of Artist Titian's daughter Lavinia...
