MEDICAL SOLDIERS of our Army are up against a big job in carrying on their work of mercy in the rapid tempo of modem mechanized war. How they are meeting the challenge with new methods and equipment is an interesting story—illustrated by comparisons with the methods and equipment of the last war.

ENGLAND’S TRADITION of always being able to “muddle through” her difficulties is again indicated by the news that she has found a substitute source for vitamin A. Prior to the war, she found it in the usual places—tomatoes, oranges, and other fruits.

PAPER GETS TOUGH
SPOT-WELDING ITS FIBERS GIVES IT GREAT STRENGTH AND RESISTANCE TO WATER
[no value]

KENNETH M. SWEZEY
BY INTERLOCKING the fibers and “spotwelding” them to each other, industrial scientists now produce paper that is amazingly strong when wet—a property which permits it to compete in many uses with burlap and cloth, releasing these materials for more urgent war needs.

FIRING live shells at real planes gives realistic practice to antiaircraft gunners, without danger to the friendly pilots, in a system devised by James C. Karnes of Buffalo, N. Y. The fire-control officer tracks the plane through the left eyepiece of a special binocular telescope, giving gun data that are exactly correct as to elevation but 180 degrees wrong as to horizontal direction.

DO YOU know how to see in the dark? New scientific tricks enable you to do it better, and more swiftly. If you step from the street into a dark movie theater, it will take several minutes to see your way around, and half an hour before your eyes’ “dark adaptation" is complete.

GOLD, THEY SAY, is where you find it. A man may discover it or he may miss it; either way he has nothing to do with creating it. Plastics are just the opposite. Plastics are what you make them. You can make them hard or soft, light or heavy, rigid or flexible, opaque or transparent.

MALARIA, which kills more than 3½ million persons every year, is an aerial blitz inflicted on man by the Anopheles mosquito. It has a higher sickness and death rate than any other disease. Tropical medicine, operating against it in its favorite haunts, the Orient and the tropics, has developed scientific methods of prevention and cure.

WILLIAM S. FRIEDMAN
ARMCHAIR AVIATORS, high-altitude radio commentators, and literary strategists have, in the last few months, managed to throw the public mind into a dither of doubt as to the value of our military aircraft. Their chief weapon has been comparison—the quotation of figures which have made some of our planes appear third-rate.

HERBERT L. STAHNKE
OF THE 40-odd species of scorpions found in the United States, two are dangerously virulent to man; their venom can, and frequently does, cause death. As far as is known, the lethal varieties of these eight-legged little monsters, which are not insects, are confined to Arizona, principally the southern half of the state, although recent reports indicate that a few, or perhaps a new species, live in Texas and California.

NATURE makes rubies and sapphires by fusing aluminum oxide in her own laboratory, the volcano, under terrific heat and pressure. Man can do the same job by dribbling aluminum oxide into an extremely hot flame formed by the union of oxygen and hydrogen, and catching the melted droplets on the end of a pointed stick.

CHAMPION weigher of the earth, Dr. Paul R. Heyl of the National Bureau of Standards, has just rechecked his last figure of 1930 with improved apparatus and slightly greater precision. By timing the swings of a horizontal or torsion pendulum between two heavy cylinders of known mass, he and an associate, Peter Chrzanowski, measured the constant of gravitation, which scientists call “g” for short.

PHOSPHORESCENT PAINT for the rims of the many dials needed in the steering and fire control of a ship is being advocated by Westinghouse engineers for use by the Navy. Prime value of this kind of paint is that it glows under black-light radiations — and would continue to glow of its own accord for several hours after an enemy bomb or torpedo had knocked out the lighting system.

AN ELECTRON is a subatomic particle of negative electricity so small that a billion billion billion would weigh less than an ounce. Singly, its power is insignificant; more than two million million million electrons must pass a given point in the filament of a 100-watt lamp each second in order to heat the lamp to normal brightness.

CELESTIAL YARDSTICK
Solves a 300-Year-Old Problem

DR. DONALD H. MENZEL
TEN YEARS of mathematical calculation, following more than a year of extensive observation by astronomers of 15 countries, have established the distance from the earth to the center of the sun at 93,005,000 miles. The new determination, which replaces the previous best value of 92,900,000 miles, was obtained by methods basically similar to the triangulation used by mundane surveyors, and is accurate within 9,000 miles, an uncertainty which corresponds to the apparent breadth of a human hair at 10 miles.

What You Should Know About Fixed Guages

This article is based upon one of a series of 16-mm. sound films prepared by the U. S. Office of Education for training war workers and distributed for the Government by Castle Films. For the machine-shop student or beginner, the value of these motion pictures cannot be overstated. They explain in the simplest and most graphic manner the operation of the standard tools and machines used in industry. Make every effort to see these films if they are being shown in your community or in the plant where you work. IF YOU were building a machine and accidentally bored a hole in a certain part .010" oversize, you could perhaps save the part from the scrap pile by turning the shaft or other piece that is to fit the hole also .010" oversize. However, if the shaft were to be made by another operator, working from a blueprint, he would presumably turn it to the size specified, and it would not fit.
