Skylark Three by E. E. Smith (free children's ebooks online TXT) 📗

[A] J. Am. Chem. Soc. 51: 3, 750.

Seaton strode into the control room with a small oblong box in his hand. Crane was seated at the desk, poring over an abstruse mathematical treatise in Science. Margaret was working upon a bit of embroidery. Dorothy, seated upon a cushion on the floor with one foot tucked under her, was reading, her hand straying from time to time to a box of chocolates conveniently near.

"Well, this is a peaceful, home-like scene—too bad to bust it up. Just finished sealing off and flashing out this case, Mart. Going to see if she'll read. Want to take a look?"

He placed the compass upon the plane table, so that its final bearing could be read upon the master circles controlled by the gyroscopes; then simultaneously started his stop-watch and pressed the button which caused a minute couple to be applied to the needle. Instantly the needle began to revolve, and for many minutes there was no apparent change in its motion in either the primary or secondary bearings.

"Do you suppose it is out of order, after all?" asked Crane, regretfully.[Pg 400]

"I don't think so," Seaton pondered. "You see, they weren't designed to indicate such distances on such small objects as men, so I threw a million ohms in series with the impulse. That cuts down the free rotation to less than half an hour, and increases the sensitivity to the limit. There, isn't she trying to quit it?"

"Yes, it is settling down. It must be on him still." Finally the ultra-sensitive needle came to rest. When it had done so, Seaton calculated the distance, read the direction, and made a reading upon Osnome.

"He's there, all right. Bearings agree, and distances check to within a light-year, which is as close as we can hope to check on as small a mass as a man. Well, that's that—nothing to do about it until after we get there. One sure thing, Mart—we're not coming straight back home from 'X'."

"No, an investigation is indicated."

"Well, that puts me out of a job. What to do? Don't want to study, like you. Can't crochet, like Peg. Darned if I'll sit cross-legged on a pillow and eat candy, like that Titian blonde over there on the floor. I know what—I'll build me a mechanical educator and teach Shiro to talk English instead of that mess of language he indulges in. How'd that be, Mart?"

"Don't do it," put in Dorothy, positively. "He's just too perfect the way he is. Especially don't do it if he'd talk the way you do—or could you teach him to talk the way you write?"

"Ouch! That's a dirty dig. However, Mrs. Seaton, I am able and willing to defend my customary mode of speech. You realize that the spoken word is ephemeral, whereas the thought, whose nuances have once been expressed in imperishable print is not subject to revision—its crudities can never be remodeled into more subtle, more gracious shading. It is my contention that, due to these inescapable conditions, the mental effort necessitated by the employment of nice distinctions in sense and meaning of words and a slavish adherence to the dictates of the more precise grammarians should be reserved for the print...."

He broke off as Dorothy, in one lithe motion, rose and hurled her pillow at his head.

"Choke him, somebody! Perhaps you had better build it, Dick, after all."

"I believe that he would like it, Dick. He is trying hard to learn, and the continuous use of a dictionary is undoubtedly a nuisance to him."

"I'll ask him. Shiro!"

"You have call, sir?" Shiro entered the room from his galley, with his unfailing bow.

"Yes. How'd you like to learn to talk English like Crane there does—without taking lessons?"

Shiro smiled doubtfully, unable to take such a thought seriously.

"Yes, it can be done," Crane assured him. "Doctor Seaton can build a machine which will teach you all at once, if you like."

"I like, sir, enormously, yes, sir. I years study and pore, but honorable English extraordinary difference from Nipponese—no can do. Dictionary useful but ..." he flipped pages dexterously, "extremely cumbrous. If honorable Seaton can do, shall be extreme ... gratification."

He bowed again, smiled, and went out.

"I'll do just that little thing. So long, folks, I'm going up to the shop."

Day after day the Skylark plunged through the vast emptiness of the interstellar reaches. At the end of each second she was traveling exactly twenty-six feet per second faster than she had been at its beginning; and as day after day passed, her velocity mounted into figures which became meaningless, even when expressed in thousands of miles per second. Still she seemed stationary to her occupants, and only different from a vessel motionless upon the surface of the Earth in that objects within her hull had lost three-sixteenths of their normal weight. Acceleration, too, had its effect. Only the rapidity with which the closer suns and their planets were passed gave any indication of the frightful speed at which they were being hurtled along by the inconceivable power of that disintegrating copper bar.

When the vessel was nearly half-way to "X," the bar was reversed in order to change the sign of their acceleration, and the hollow sphere spun through an angle of one hundred and eighty degrees around the motionless cage which housed the enormous gyroscopes. Still apparently motionless and exactly as she had been before, the Skylark was now actually traveling in a direction which seemed "down" and with a velocity which was being constantly decreased by the amount of their negative acceleration.

A few days after the bar had been reversed Seaton announced that the mechanical educator was complete, and brought it into the control room.

In appearance it was not unlike a large radio set, but it was infinitely more complex. It possessed numerous tubes, kino-lamps, and photo-electric cells, as well as many coils of peculiar design—there were dozens of dials and knobs, and a multiple set of head-harnesses.

"How can a thing like that possibly work as it does?" asked Crane. "I know that it does work, but I could scarcely believe it, even after it had educated me."

"That is nothing like the one Dunark used, Dick," objected Dorothy. "How come?"

"I'll answer you first, Dot. This is an improved model—it has quite a few gadgets of my own in it. Now, Mart, as to how it works—it isn't so funny after you understand it—it's a lot like radio in that respect. It operates on a band of frequencies lying between the longest light and heat waves and the shortest radio waves. This thing here is the generator of those waves and a very heavy power amplifier. The headsets are stereoscopic transmitters, taking or receiving a three-dimensional view. Nearly all matter is transparent to those waves; for instance bones, hair, and so on. However, cerebin, a cerebroside peculiar to the thinking structure of the brain, is opaque to them. Dunark, not knowing chemistry, didn't know why the educator worked or what it worked on—he found out by experiment that it did work; just as we found out about electricity. This three-dimensional model, or view, or whatever you want to call it, is converted into electricity in the headsets, and the resulting modulated wave goes back to the educator. There it is heterodyned with another wave—this second frequency was found after thousands of trials and is, I believe, the exact frequency existing in the optic nerves themselves—and sent to the receiving headset. Modulated as it is, and producing a three-dimensional picture, after rectification in the receiver, it reproduces exactly what has been 'viewed,' if due allowance has been made for the size and configuration of the different brains involved in the transfer. You remember a sort of flash—a[Pg 401] sensation of seeing something—when the educator worked on you? Well, you did see it, just as though it had been transmitted to the brain by the optic nerve, but everything came at once, so the impression of sight was confused. The result in the brain, however, was clear and permanent. The only drawback is that you haven't the visual memory of what you have learned, and that sometimes makes it hard to use your knowledge. You don't know whether you know anything about a certain subject or not until after you go digging around in your brain looking for it."
