Everyone knew the existence of those robots and there is no record of any attempt at theft, ever.
And then, of course, there was her light-sculpture. How Mrs. Lardner discovered her own genius at the art, no guest at her many lavish entertainments could guess. On each occasion, however, when her house was thrown open to guests, a new symphony of light shone throughout the rooms; three-dimensional curves and solids in melting color, some pure and some fusing in startling, crystalline effects that bathed every guest in wonder and somehow always adjusted itself so as to make Mrs. Lardner"s blue-white hair and soft, unlined face gently beautiful.
It was for the light-sculpture more than anything else that the guests came. It was never the same twice, and never failed to explore new experimental avenues of art. Many people who could afford light-consoles prepared light-sculptures for amus.e.m.e.nt, but no one could approach Mrs. Lardner"s expertise. Not even those who considered themselves professional artists.
She herself was charmingly modest about it. "No, no," she would protest when someone waxed lyrical. "I wouldn"t call it "poetry in light." That"s far too kind. At most, I would say it was mere "light verse."" And everyone smiled at her gentle wit.
Though she was often asked, she would never create light-sculpture for any occasion but her own parties. "That would be commercialization," she said.
She had no objection, however, to the preparation of elaborate holograms of her sculptures so that they might be made permanent and reproduced in museums of art an over the world. Nor was there ever a charge for any use that might be made of her light-sculptures.
"I couldn"t ask a penny," she said, spreading her arms wide. "It"s free to all. After all, I have no further use for it myself." It was truer She never used the same light-sculpture twice.
When the holograms were taken, she was cooperation itself. Watching benignly at every step, she was always ready to order her robot servants to help. "Please, Courtney," she would say, "would you be so kind as to adjust the step ladder?"
It was her fashion. She always addressed her robots with the most formal courtesy.
Once, years before, she had been almost scolded by a government functionary from the Bureau of Robots and Mechanical Men. "You can"t do that," he said severely. "It interferes with their efficiency. They are constructed to follow orders, and the more clearly you give those orders, the more efficiently they follow them. When you ask with elaborate politeness, it is difficult for them to understand that an order is being given. They react more slowly."
Mrs. Lardner lifted her aristocratic head. "I do not ask for speed and efficiency," she said. "I ask goodwill. My robots love me."
The government functionary might have explained that robots cannot love, but he withered under her hurt but gentle glance.
It was notorious that Mrs. Lardner never even returned a robot to the factory for adjustment. Their positronic brains are enormously complex, and once in ten times or so the adjustment is not perfect as it leaves the factory. Sometimes the error does not show up for a period of time, but whenever it does, u. S. Robots and Mechanical Men, Inc., always makes the adjustment free of charge.
Mrs. Lardner shook her head. "Once a robot is in my house," she said, "and has performed his duties, any minor eccentricities must be borne with. I will not have him manhandled."
It was the worse thing possible to try to explain that a robot was but a machine. She would say very stiffly, "Nothing that is as intelligent as a robot can ever be but but a machine. I treat them as people." a machine. I treat them as people."
And that was that!
She kept even Max, although he was almost helpless. He could scarcely understand what was expected of him. Mrs. Lardner denied that strenuously, however. "Not at all," she would say firmly. "He can take hats and coats and store them very well, indeed. He can hold objects for me. He can do many things."
"But why not have him adjusted?" asked a friend, once.
"Oh, I couldn"t. He"s himself. He"s very lovable, you know. After all, a positronic brain is so complex that no one can ever tell in just what way it"s off. If he were made perfectly normal there would be no way to adjust him back to the lovability he now has. I won"t give that up."
"But if he"s maladjusted," said the friend, looking at Max nervously, "might he not be dangerous?"
"Never," laughed Mrs. Lardner. "I"ve had him for years. He"s completely harmless and quite a dear."
Actually he looked like all the other robots, smooth, metallic, vaguely human but expressionless.
To the gentle Mrs. Lardner, however, they were all individual, all sweet, all lovable. It was the kind of woman she was.
How could she commit murder?
The very last person anyone would expect to be murdered would be John Semper Travis. Introverted and gentle, he was in the world but not of it. He had that peculiar mathematical turn of mind that made it possible for him to work out in his mind the complicated tapestry of the myriad positronic brain-paths in a robot"s mind.
He was chief engineer of U.S. Robots and Mechanical Men, Inc.
But he was also an enthusiastic amateur in light-sculpture. He had written a book on the subject, trying to show that the type of mathematics he used in working out positronic brain-paths might be modified into a guide to the production of aesthetic light-sculpture.
His attempt at putting theory into practice was a dismal failure, however. The sculptures he himself produced, following his mathematical principles, were stodgy, mechanical, and uninteresting.
It was the only reason for unhappiness in his quiet, introverted, and secure life, and yet it was reason enough for him to be very unhappy indeed. He knew knew his theories were right, yet he could not make them work. If he could but produce his theories were right, yet he could not make them work. If he could but produce one one great piece of light-sculpture. great piece of light-sculpture.
Naturally, he knew of Mrs. Lardner"s light-sculpture. She was universally hailed as a genius, yet Travis knew she could not understand even the simplest aspect of robotic mathematics. He had corresponded with her but she consistently refused to explain her methods, and he wondered if she had any at all. Might it not be mere intuition? -but even intuition might be reduced to mathematics. Finally he managed to receive an invitation to one of her parties. He simply had to see her.
Mr. Travis arrived rather late. He had made one last attempt at a piece of light-sculpture and had failed dismally.
He greeted Mrs. Lardner with a kind of puzzled respect and said, "That was a peculiar robot who took my hat and coat."
"That is Max," said Mrs. Lardner.
"He is quite maladjusted, and he"s a fairly old model. How is it you did not return it to the factory?"
"Oh, no," said Mrs. Lardner. "It would be too much trouble."
"None at all, Mrs. Lardner," said Travis. "You would be surprised how simple a task it was. Since I am with U. S. Robots, I took the liberty of adjusting him myself. It took no time and you"ll find he is now in perfect working order."
A queer change came over Mrs. Lardner"s face. Fury found a place on it for the first time in her gentle life, and it was as though the lines did not know how to form.
"You adjusted him?" she shrieked. "But it was he he who created my light-sculptures. It was the maladjustment, the who created my light-sculptures. It was the maladjustment, the maladjustment, maladjustment, which you can never restore, that-that-" which you can never restore, that-that-"
It was really unfortunate that she had been showing her collection at the time and that the jeweled dagger from Cambodia was on the marble tabletop before her.
Travis"s face was also distorted. "You mean if I had studied his uniquely maladjusted positronic brain-paths I might have learned-"
She lunged with the knife too quickly for anyone to stop her and he did not try to dodge. Some said he came to meet it-as though he wanted wanted to die. to die.
The Feeling of Power
Jehan Shuman was used to dealing with the men in authority on long-embattled Earth. He was only a civilian but he originated programming patterns that resulted in self-directing war computers of the highest sort. Generals consequently listened to him. Heads of congressional committees, too.
There was one of each in the special lounge of New Pentagon. General Weidef was s.p.a.ce-burnt and had a small mouth puckered almost into a cipher. Congressman Brant was smooth-cheeked and clear-eyed. He smoked Denebian tobacco with the air of one whose patriotism was so notorious, he could be allowed such liberties.
Shuman, tall, distinguished, and Programmer-first-cla.s.s, faced them fearlessly.
He said, "This, gentlemen, is Myron Aub."
"The one with the unusual gift that you discovered quite by accident," said Congressman Brant placidly. "Ah." He inspected the little man with the egg-bald head with amiable curiosity.
The little man, in return, twisted the fingers of his hands anxiously. He had never been near such great men before. He was only an aging low-grade Technician who had long ago failed all tests designed to smoke out the gifted ones among mankind and had settled into the rut of unskilled labor. There was just this hobby of his that the great Programmer had found out about and was now making such a frightening fuss over.
General Weider said, "I find this atmosphere of mystery childish."
"You won"t in a moment," said Shuman. "This is not something we can leak to the firstcomer. -Aub!" There was something imperative about his manner of biting off that one-syllable name, but then he was a great Programmer speaking to a mere Technician. "Aub! How much is nine times seven?"
Aub hesitated a moment. His pale eyes glimmered with a feeble anxiety. "Sixty-three," he said.
Congressman Brant lifted his eyebrows. "Is that right?"
"Check it for yourself, Congressman."
The congressman took out his pocket computer, nudged the milled edges twice, looked at its face as it lay there in the palm of his hand, and put it back. He said, "Is this the gift you brought us here to demonstrate? An illusionist?"
"More than that, sir. Aub has memorized a few operations and with them he computes on paper."
"A paper computer?" said the general. He looked pained.
"No, sir," said Shuman patiently. "Not a paper computer. Simply a sheet of paper. General, would you be so kind as to suggest a number?"
"Seventeen," said the general.
"And you, Congressman?"
"Twenty-three."
"Good! Aub, multiply those numbers and please show the gentlemen your manner of doing it."
"Yes, Programmer," said Aub, ducking his head. He fished a small pad out of one shirt pocket and an artist"s hairline stylus out of the other. His forehead corrugated as he made painstaking marks on the paper.
General Weider interrupted him sharply. "Let"s see that."
Aub pa.s.sed 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 pa.s.sable 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 G.o.dfrey, 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?"
