The Invisible X-Flyers
The following is a semi-technical description of the operation of the invisible X-flyers used in "Jetta of the Lowlands" as compiled by Philip Grant in the year 2021 from official records of the Anti-War Department of the United States of North America, and discovered recently by Ray Cummings.
The attainment of mechanical invisibility reached a state of perfection in the year 2000 sufficient to make it practical for many uses. For a century this result had been sought. It came, about the year 2000, not as a single startling discovery, but as the culmination of the patient labor of many men during many years. The popular mind has always considered that science advances by a series of "great scientific discoveries"; "unprecedented"; "revolutionary." That is not so. Each step in the progress of scientific achievement is built most carefully upon the one beneath it. And generally the "revolutionary, unprecedented discovery" has very little of itself that is new; rather it is a new combination of older, perhaps seemingly impractical knowledge. Every scientific theory, every device, is the offspring from a large and varied family tree of many scientific ancestors, each of whom in his day was a remarkable personage.
Thus it is, with the principles of mechanical invisibility. I deal here with the famous X-flyers. The operation of the plane itself is immaterial; its motors; its wing-spread surfaces; its aerial controls. I am concerned only with the scientific principles underlying its power of invisibility.
Three scientific factors are involved: First, the process known as de-electroniration; second, the theories of color absorption; third, the material, inevitable deflection (bending) of light rays when passing through a magnetic field.
I take each of the three in order. The forerunners of de-electroniration were the Martel effects—the experiments of Charles Martel, in Paris, in 1937. A new electric current, of a different character—now called the oscillating current as distinct from the alternating and direct—was developed. Metallic plates were electro-magnetized to produce an enveloping magnetic field of somewhat a different character from any field formerly known.
Dr. Norton Grenfell followed this in 1946 by using the Martel oscillating current to obtain a reverse effect. A similar disturbance of electrode balance. But not a surcharge. An exhaustion. An anti-electrical state, instead of a state of magnetism. A metallic mass so treated—and with a constant flow of oscillating current holding its subnormal electronic balance—was then said to be de-electronired.
Scientific "discoveries" are largely made by the trial and error system. The scientist takes what he finds. Generally he does not know, at first, what it means. Martell took his oscillating current and "discovered" the Martel Magnetic Levitation, whereby gravity was lessened, and then completely nullified. Grenfell, with his de-electroniration, increased the power of gravity. The two were combined by Grenfell and his associates—and the secret of interplanetary flight was at hand.
But there was a host of other workers not interested in space flyers; they probed in other directions. It was found that the subnormal magnetic field surrounding a metallic substance in a state of de-electroniration had two unusual properties: its color absorption was high; and it bent light rays from their normal straight path into a curve abnormally great. Yet, though it absorbed the color of the rays emanating from the de-electronired metal (the metal itself increasing this result), the magnetic field, while bending the rays passing through it from distant objects behind it, nevertheless left their color and all their inherent properties unchanged.
The principles of color absorption are these:—a pigment—a paint, a dye, if you will—is "red" because it absorbs from the light rays of the sun all the other colors and leaves only red to be reflected from it to the eye. Or "violet" because all the rest are absorbed, and the violet is reflected. Or "black" because all are absorbed; and "white" the reverse, all blended and reflected. Color is dependent upon vibratory motion. The solar spectrum—its range of visibility through the primary colors from red to violet—can be likened to a range of radio wave-lengths; vibration frequencies; and when we eliminate them all save the "violet"—that is what we have left, in the radio to hear, in color absorption to see.
