Jobs from Research
By Everett S. Lee Engineer-in-Charge, General Engineering Laboratory, General Electric Company FIFTEEN million Americans are at work today in jobs that did not exist in 1900. These jobs exist today because, through research, industry has been able to develop hundreds of new products and to make them so inexpensive that people have been able to buy them, thus creating a demand for more of the products. The recent report of over 1,700 distinct research groups in this country, affording employment to some 50,000 workers, with an annual expenditure of from 150 to 200 million dollars, with an existence dating back some forty years indicates the importance of research.

The "TALKING MACHINE" Comes Back
HOW would you like to make a record of your favorite radio program to play on your phonograph? Or reproduce an historic radio speech, or the voice of a friend singing to the accompaniment of a world-famous orchestra? You can do all that and more with the latest all-purpose musical instrument, the combination radio, phonograph, and home recorder. Using the recorder attachment, you can collect and save the voices of children, reproduce music from the radio or from other phonograph records, and create music and dialogue for home movies. Your records will have almost the same quality as professional recordings and you can play them back on the phonograph as soon as you have made them. The disks cost as little as fifteen cents for a size that plays one and one-half minutes. Each record may be played a hundred times or more before it wears out.

War the Destroyer
Mighty machines of destruction are razing homes, churches, schools, factories and other buildings of Europe's warring nations, converting the struggle into a contest of civilian stamina, rather than a meeting of armed forces. Air armadas, heavily laden with bombs, attack the enemy's principal cities, sometimes in raids lasting virtually around the clock, and leave horrible trails of desolation; yet the civilian population rises from the ruins and begins a never-ending task of clearing away the debris and repairing the damage even before the roar of departing raiding planes vanishes. And so the battle for air supremacy goes on. Above, a home "somewhere in England'9 with bathroom caved in by bomb explosion. An air-raid officer removes articles from the home and hands them to the girls standing on debris. Right, wheeling up a torpedo to be fixed in rack beneath a British bombing plane that will take off to strike in retaliation at some German city. Below, concussion from a bursting bomb hurled this huge bus against a building in London. Its occupants had time to seek shelter before the bus was upset. Here air-raid workers are lowering the vehicle to the street. Scenes like this have been common in raided cities

Electrons in Overalls
WHILE millions of men throughout the world have been frantically engaged in destructive warfare waged by new and secret devices, during the last few years, several hundred earnest American scientists have been just as busy training an army of their own and perfecting a weapon which may go a long way toward making a better civilization tomorrow. The army of the scientists is an army of electrons, countless billions strong. The weapon is the electronic tube—no secret weapon, to be sure, because among the common types are the tubes in your radio.

Uncle Sam's School for Sailors
WHEN you march through the main gate of the Naval Training Station at San Diego, Calif., as a raw recruit you leave the land behind. You will spend two months learning to be a sailor before you are assigned to the battle fleet but even though you are still on dry land, things are a lot like they are at sea. In a couple of days you will know that a floor is really a deck and you'll not make the mistake of calling a bulkhead a wall. You will ask whether the smoking lamp is lit instead of whether you may smoke and you will be telling time by ship's bells instead of by hours.
