Dhvongh the davk of night, and the heat of day, America’s plane spotters hate kept they lonely watch. Theirs ts @ Job without recompense, without glory, without even the thrill of darger==yet they have kept to thery posts. But theve ave times, when the fog volls tn ov the shies ave dark, that even the deemest human eyes ave wot enough, Then, along our shoves and about our cities, we can depend on electrons semtries to scam the skis,

What is Electronics, Anyway?

1. What is an electron?

The electron is one of the fundamental particles of matter and electricity. Electrons are part of atoms; atoms make up molecules. And molecules, in tur, make up all the matter in the world, and in the unis verse of which the world is but a small part. The eleetron is far too small to be seen, even with the best microscopes. Thirty thousand trillion trillion electrons would weigh less than one ounce! Electronics is the science of electrons.

. Who discovered electronics?

No one person. Electronics has grown as the result of the work of many scientists, in many countries, over the past 60 years. It is growing faster today than ever before, as scientists learn more about electrons and how to use them.

. What is the difference between an electronic

tube and a radio tube?

A radio tube is one of the many kinds of electron tubes. They are as varied as the jobs they do. Some are small as a thimble, others big as a man. Some are vacuum tubes, others contain rare gases. Some are made of glass, others of steel. New types are being developed all the time,

Is television an electronic development?

Yee. So is the radio, the X-ray, radar. Electronic tubes work in the long-distance telephone; they control important processes in industry; they count and sort and safeguard. New uses are being found almost every day,

. What does electronics promise for the future?

Many things. New products and services, new medical tools to help safeguard human health. Perhaps equally important, it will give us a tool by which we can make things faster, better, and cheaper, so that we can all afford more of them.

RA DAR is America’s best plane spotter. Like the bat, which is equipped by nature with one of the most remarkable sets of blind-flying “instruments” known to man, radar can operate “blind” in night and fog. Waves from electronic tubes, incessantly scanning the skies, can “feel” through the dark the approach of an enemy plane. Radar, and the Spitfires, stopped the Stukas in the skies over England in 1940. Radar, helping to direct the fire of an American warship in the Pacific, enabled it to hit a Japanese warship 8 miles away in pitch darkness, Yet radar is no more mis raculous than your radio set, It is simply the application of principles discovered many years ago. Many scientists and engineers=in this country and in Britain, some working alone, some in the Army and Navy, many in college and industrial research laboratories—played a part in its development. And Gene eral Electric was oneof the first and most active in this field. This was only natural. For, when in 1940 the Navy re quested G.E. to begin the manufacture of radar equip« ment, we had been for more than 20 years engaged in the development and manufacture of the kind of electron tubes, circuits, and apparatus that makes radio, and radar, possible. Additional manufacturing facilities were started at once. And today, General Electric is supplying this equipment in quantity for the Army and the Navy,

nga 3 Electronics is a Peacetime Science: We know it best through radio, a great and essential industry, But electronics works in almost every other industry, too measuring in millionths of an inch, converting electric current to heat steel furnaces and to refine aluminum and magnesium, seeing through inches of steel, protecting property and human lives, regulating lighting. And electroni¢ controls enable women to do many complex jobs in industry, releasing men for war. ) But the destiny of elecs AN tronics is not to replace=it is to add to the products and services we enjoy, and to make easier our ways of obtaining them. Things like television merely await the war's end. And in the elec tronic laboratories of today are the seeds of other, of new and undreamed-of benefits for tomorrow.
