THIS is Paul J. Ovando, one of the thousands of science students whose careers were interrupted by the war. After service in the Navy, he is now back at Columbia. It will be 1950 before he gets his degree in medicine. Understandably, such members of the lost generation of young scientists are working long and hard to make up for time lost.

Sir: I noticed an article in a recent issue concerning the athodyd jet and its application to small planes. This article shows the jet placed in the tip of the propeller in conventional style. I have thought of a design which places these jets closer to the hub, in the form of an engine, in order to get more power for larger planes, etc.

IN GENERAL ELECTRIC'S High Voltage Laboratories, at Pittsfield, Mass., lightning crashes across 30-foot gaps to lest FM radio sets under thunder-shower reception. Man-made lightning-up to 10,000,000 volts-is created when capacitors, each storing 100,000 volts, are stacked in two groups several feet apart, fully charged, and then short-circuited.

WILLIAM P. VOGEL
THIS month television starts its postwar campaign for public acclaim. After years in the laboratory and months of limited commercial operation, it is now out to conquer an audience. Those who already own television sets (at a guess, about 10,000 families) will get at least four hours of sight-and-sound each week this month.

PILOTS without radar experience, or a lot of special equipment, can land safely in the thickest fog when guided by the Navy’s mobile GCA (Ground Controlled Approach) system. To use this war-born technique for radar landings, a pilot needs only a twoway radio, basic knowledge of instrument flying — and confidence.

A $250,000 HOUSE with every available postwar convenience, and some not yet for sale, has been built by a Los Angeles contractor to show how much scientific luxury a home can offer. Fritz B. Burns, who with Henry J. Kaiser plans to produce 10,000 moderately priced prefabricated houses for crowded Californians by next June, knows that his palace of improvements is way out of the average house hunter’s reach.

THANKS to a young Yankee inventor, the average weather enthusiast will soon be able to tell how hard the wind is blowing and from what direction without stirring from his comfortable chair by the fire. John A. Hastings, of Bass River, Mass., has devised an inexpensive anemometer-weather vane that uses simple electrical circuits to transmit information about the wind from the roof to a dial anywhere in the house.

CHESS players who are also workshop enthusiasts will derive double enjoyment from this project. Craftsmen not adept at chess will still find interest in the turning, and the set will make an ideal gift. Use of 1" maple doweling simplifies the job of turning if the stock is close-grained and free from blemishes.

IN THESE streamlined times, George Washington’s coach may look like an ornate relic of a distant age. But on close examination even the modern eye will be struck by the simplicity of its lines. Perhaps this simplicity appealed to America’s first President; certainly the rude roads of the times demanded a vehicle both light and sturdy.

When it is used on the bench, a block is slipped under the crank-housing end, and a block may likewise be put under the dolly bar for additional support on large-diameter work.

GEORGE O. SMITH
FILTERS are electronic circuits that have frequency selectivity. At the will of the designer, they can be made to pass or block frequencies below, above, between, or around certain specified limits. The names of the four major types are self-explanatory; they are low-pass, high-pass, band-pass, and band-elimination filters.

THE film in your camera is thinly coated with one of the most unstable chemicals known to man.

The intricate and far-reaching changes brought to silver bromide by that flash of light are in part still secrets of nature.

THE Editor’s Easy Chair at Popular Science Monthly is a varied seat. It may be a lounge chair in a new air liner or the hard, cold metal “bucket” of a military transport, a Pullman bedroom or standing room in a day coach on an early train. Sometimes it is a swivel chair in the editorial offices.
