General Weider interrupted him sharply. "Let's see that."
Aub passed him the paper, and Weider said, "Well, it looks like the figure seventeen."
Congressman Brant nodded and said, "So it does, but I suppose anyone can copy figures off a computer. I think I could make a passable seventeen myself, even without practice."
"If you will let Aub continue, gentlemen," said Shuman without heat.
Aub continued, his hand trembling a little. Finally he said in a low voice, "The answer is three hundred and ninety-one."
Congressman Brant took out his computer a second time and flicked it, "By Godfrey, so it is. How did he guess?"
"No guess, Congressman," said Shuman. "He computed that result. He did it on this sheet of paper."
"Humbug," said the general impatiently. "A computer is one thing and marks on paper are another."
"Explain, Aub," said Shuman.
"Yes, Programmer. -Well, gentlemen, I write down seventeen and just
underneath it, I write twenty-three. Next, I say to myself: seven times three-"
The congressman interrupted smoothly, "Now, Aub, the problem is seventeen times twenty-three."
"Yes, I know," said the little Technician earnestly, "but I start by saying seven times three because that's the way it works. Now seven times three is twenty-one."
"And how do you know that?" asked the congressman.
"I just remember it. It's always twenty-one on the computer. I've checked it any number of times."
"That doesn't mean it always will be, though, does it?" said the congressman.
"Maybe not," stammered Aub. "I'm not a mathematician. But I always get the right answers, you see."
"Go on."
"Seven times three is twenty-one, so I write down twenty-one. Then one times three is three, so I write down a three under the two of twenty-one."
"Why under the two?" asked Congressman Brant at once.
"Because-" Aub looked helplessly at his superior for support. "It's difficult to explain."
Shuman said, "If you will accept his work for the moment, we can leave the details for the mathematicians."
Brant subsided.
Aub said, "Three plus two makes five, you see, so the twenty-one becomes a fifty-one. Now you let that go for a while and start fresh. You multiply seven and two, that's fourteen, and one and two, that's two. Put them down like this and it adds up to thirty-four. Now if you put the thirty-four under the fifty-one this way and add them, you get three hundred and ninety-one and that's the answer."
There was an instant's silence and then General Weider said, "I don't believe it. He goes through this rigmarole and makes up numbers and multiplies and adds them this way and that, but I don't believe it. It's too complicated to be anything but homswoggling."
"Oh no, sir," said Aub in a sweat. "It only seems complicated because you're not used to it. Actually, the rules are quite simple and will work for any numbers."
"Any numbers, eh?" said the general. "Come then." He took out his own computer (a severely styled GI model) and struck it at random. "Make a five seven three eight on the paper. That's five thousand seven hundred and thirty-eight."
"Yes, sir," said Aub, taking a new sheet of paper.
"Now," (more punching of his computer), "seven two three nine. Seven thousand two hundred and thirty-nine."
"Yes, sir."
"And now multiply those two."
"It will take some time," quavered Aub.
"Take the time," said the general.
"Go ahead, Aub," said Shuman crisply.
Aub set to work, bending low. He took another sheet of paper and another. The general took out his watch finally and stared at it. "Are you through with your magic-making, Technician?"
"I'm almost done, sir. -Here it is, sir. Forty-one million, five hundred and thirty-seven thousand, three hundred and eighty-two." He showed the scrawled figures of the result.
General Weider smiled bitterly. He pushed the multiplication contact on his computer and let the numbers whirl to a halt. And then he stared and said in a surprised squeak, "Great Galaxy, the fella's right."
The President of the Terrestrial Federation had grown haggard in office and, in private, he allowed a look of settled melancholy to appear on his sensitive features. The Denebian war, after its early start of vast movement and great popularity, had trickled down into a sordid matter of maneuver and countermaneuver, with discontent rising steadily on Earth. Possibly, it was rising on Deneb, too.
And now Congressman Brant, head of the important Committee on Military Appropriations, was cheerfully and smoothly spending his half-hour appointment spouting nonsense.
"Computing without a computer," said the president impatiently, "is a contradiction in terms."
"Computing," said the congressman, "is only a system for handling data. A machine might do it, or the human brain might. Let me give you an example." And, using the new skills he had learned, he worked out sums and products until the president, despite himself, grew interested.
"Does this always work?"
"Every time, Mr. President. It is foolproof."
"Is it hard to learn?"
"It took me a week to get the real hang of it. I think you would do better."
"Well," said the president, considering, "it's an interesting parlor game, but what is the use of it?"
"What is the use of a newborn baby, Mr. President? At the moment there is no use, but don't you see that this points the way toward liberation from the machine. Consider, Mr. President," the congressman rose and his deep voice automatically took on some of the cadences he used in public debate, "that the Denebian war is a war of computer against computer. Their computers forge an impenetrable shield of counter-missiles against our missiles, and ours forge one against theirs. If we advance the efficiency of
