The Skylark of Space by E. E. Smith (books like beach read .TXT) 📕

“I have various ways of getting information. I know Dick Seaton better than you do⁠—better than he knows himself. I have known all about every man who ever looked at you twice. I have been afraid once or twice that I would have to take a hand, but you saw them right, just as you see Seaton right. For some time I have been afraid of the thought of your marrying, the young men in your social set are such a hopeless lot, but I am not any more. When I hand my little girl over to her husband next October I can be really happy with you, instead of anxious for you. That’s how well I know Richard Seaton⁠ ⁠… Well, good night, daughter mine.”

“Good night, Daddy dear,” she replied, throwing her arms around his neck. “I have the finest Dad a girl ever had, and the finest⁠ ⁠… boy. Good night.”

It was three o’clock the following afternoon when Seaton appeared in the laboratory. His long rest had removed all the signs of overwork and he was his alert, vigorous self, but when Crane saw him and called out a cheery greeting he returned it with a sheepish smile.

“Don’t say anything, Martin⁠—I’m thinking it all, and then some. I made a regular fool of myself last night. Went to sleep in a chair and slept seventeen hours without a break. I never felt so cheap in my life.”

“You were worn out, Dick, and you know it. That sleep put you on your feet again, and I hope you will have sense enough to take care of yourself after this. I warn you now, Dick, that if you start any more of that midnight work I will simply call Dorothy over here and have her take charge of you.”

“That’s it, Mart, rub it in. Don’t you see that I am flat on my back, with all four paws in the air? But I’m going to sleep every night. I promised Dottie to go to bed not later than twelve, if I have to quit right in the middle of an idea, and I told her that I was coming out to see her every other evening and every Sunday. But here’s the dope. I’ve got that missing factor in my theory⁠—got it while I was eating breakfast this afternoon.”

“If you had eaten and slept regularly here and kept yourself fit you would have seen it before.”

“Yes, I guess that’s right, too. If I miss a meal or a sleep from now on I want you to sandbag me. But never mind that. Here’s the explanation. We doped out before, you know, that the force is something like magnetism, and is generated when the coil causes the electrons of this specially-treated copper to vibrate in parallel planes. The knotty point was what could be the effect of a weak electric current in liberating the power. I’ve got it! It shifts the plane of vibration of the electrons!”

“It is impossible to shift that plane, Dick. It is fixed by physical state, just as speed is fixed by temperature.”

“No, it isn’t. That is, it usually is, but in this case it may be shifted. Here’s the mathematical proof.”

So saying, Seaton went over to the drafting table, tacked down a huge sheet of paper, and sketched rapidly, explaining as he drew. Soon the two men were engaged in a profound mathematical argument. Sheet after sheet of paper was filled with equations and calculations, and the table was covered with reference books. After two hours of intense study and hot discussion Crane’s face took on a look of dawning comprehension, which changed to amazement and then to joy. For the first time in Seaton’s long acquaintance with him, his habitual calm was broken.

“By George!” he cried, shaking Seaton’s hand in both of his. “I think you have it! But how under the sun did you get the idea? That calculus isn’t in any of the books. Where did you get it? Dick, you’re a wonder!”

“I don’t know how I got the idea, it merely came to me. But that Math is right⁠—it’s got to be right, no other conclusion is possible. Now, if that calc. is right, and I know it is, do you see how narrow the permissible limits of shifting are? Look at equation 236. Believe me, I sure was lucky, that day in the Bureau. It’s a wonder I didn’t blow up the whole works. Suppose I hadn’t been working with a storage cell that gave only four amperes at two volts? That’s unusually low, you know, for that kind of work.”

Crane carefully studied the equation referred to and figured for a moment.

“In that case the limit would be exactly eight watts. Anything above that means instant decomposition?”

“Yes.”

Crane whistled, a long, low whistle.

“And that bath weighed forty pounds⁠—enough to vaporize the whole planet. Dick, it cannot be possible.”

“It doesn’t seem that way, but it is. It certainly makes me turn cold all over, though, to think of what might have happened. You know now why I wouldn’t touch the solution again until I had this stuff worked out?”

“I certainly do. You should be even more afraid of it now. I don’t mind nitroglycerin or T.N.T., but anything like that is merely a child’s plaything compared to this. Perhaps we had better drop it?”

“Not in seven thousand years. The mere fact that I was so lucky at first proves that Fate intended this thing to be my oyster. However, I’ll not tempt the old lady any farther. I’m going to start with one millionth of a volt, and will use a piece of copper visible only under a microscope. But there’s absolutely no danger, now that we know what it is. I can make it eat out of my hand. Look at this equation here, though. That being true, it looks as though you could get the same explosive effect by taking a piece of copper which had once been
