The Golden Age Of Science Fiction Vol V Part 10

"I am seventy-five years of age. I have, in this year 2004, been studying 'time' for thirty of those years. I have completed the first time machine ever built-and thus far, its construction, even the fact that it has been constructed, is my own secret.

"You have just partic.i.p.ated in the first major experiment. It will be your responsibility to decide whether there shall ever be any more experiments with it, whether it should be given to the world, or whether it should be destroyed and never used again."

End of the first page. You look up for a moment, hesitating to turn the next page. Already you suspect what is coming.

You turn the page.

"I constructed the first time machine a week ago. My calculations had told me that it would work, but not how it would work. I had expected it to send an object back in time-it works backward in time only, not forward-physically unchanged and intact.

"My first experiment showed me my error. I placed a cube of metal in the machine-it was a miniature of the one you just walked out of-and set the machine to go backward ten years. I flicked the switch and opened the door, expecting to find the cube vanished. Instead I found it had crumbled to powder.

"I put in another cube and sent it two years back. The second cube came back unchanged, except that it was newer, s.h.i.+nier.

"That gave me the answer. I had been expecting the cubes to go back in time, and they had done so, but not in the sense I had expected them to. Those metal cubes had been fabricated about three years previously. I had sent the first one back years before it had existed in its fabricated form. Ten years ago it had been ore. The machine returned it to that state.

"Do you see how our previous theories of time travel have been wrong? We expected to be able to step into a time machine in, say, 2004, set it for fifty years back, and then step out in the year 1954 ... but it does not work that way. The machine does not move in time. Only whatever is within the machine is affected, and then just with relation to itself and not to the rest of the Universe.

"I confirmed this with guinea pigs by sending one six weeks old five weeks back and it came out a baby.

"I need not outline all my experiments here. You will find a record of them in the desk and you can study it later.

"Do you understand now what has happened to you, Norman?"

You begin to understand. And you begin to sweat.

The I who wrote that letter you are now reading is you, yourself at the age of seventy-five, in this year of 2004. You are that seventy-five-year-old man, with your body returned to what it had been fifty years ago, with all the memories of fifty years of living wiped out.

You invented the time machine.

And before you used it on yourself, you made these arrangements to help you orient yourself. You wrote yourself the letter which you are now reading.

But if those fifty years are-to you-gone, what of all your friends, those you loved? What of your parents? What of the girl you are going-were going-to marry?

You read on: "Yes, you will want to know what has happened. Mom died in 1963, Dad in 1968. You married Barbara in 1956. I am sorry to tell you that she died only three years later, in a plane crash. You have one son. He is still living; his name is Walter; he is now forty-six years old and is an accountant in Kansas City."

Tears come into your eyes and for a moment you can no longer read. Barbara dead-dead for forty-five years. And only minutes ago, in subjective time, you were sitting next to her, sitting in the bright sun in a Beverly Hills patio ...

You force yourself to read again.

"But back to the discovery. You begin to see some of its implications. You will need time to think to see all of them.

"It does not permit time travel as we have thought of time travel, but it gives us immortality of a sort. Immortality of the kind I have temporarily given us.

"Is it good? Is it worth while to lose the memory of fifty years of one's life in order to return one's body to relative youth? The only way I can find out is to try, as soon as I have finished writing this and made my other preparations.

"You will know the answer.

"But before you decide, remember that there is another problem, more important than the psychological one. I mean overpopulation.

"If our discovery is given to the world, if all who are old or dying can make themselves young again, the population will almost double every generation. Nor would the world-not even our own relatively enlightened country-be willing to accept compulsory birth control as a solution.

"Give this to the world, as the world is today in 2004, and within a generation there will be famine, suffering, war. Perhaps a complete collapse of civilization.

"Yes, we have reached other planets, but they are not suitable for colonizing. The stars may be our answer, but we are a long way from reaching them. When we do, someday, the billions of habitable planets that must be out there will be our answer ... our living room. But until then, what is the answer?

"Destroy the machine? But think of the countless lives it can save, the suffering it can prevent. Think of what it would mean to a man dying of cancer. Think ..."

Think. You finish the letter and put it down.

You think of Barbara dead for forty-five years. And of the fact that you were married to her for three years and that those years are lost to you.

Fifty years lost. You d.a.m.n the old man of seventy-five whom you became and who has done this to you ... who has given you this decision to make.

Bitterly, you know what the decision must be. You think that he knew, too, and realize that he could safely leave it in your hands. d.a.m.n him, he should have known.

Too valuable to destroy, too dangerous to give.

The other answer is painfully obvious.

You must be custodian of this discovery and keep it secret until it is safe to give, until mankind has expanded to the stars and has new worlds to populate, or until, even without that, he has reached a state of civilization where he can avoid overpopulation by rationing births to the number of accidental-or voluntary-deaths.

If neither of those things has happened in another fifty years (and are they likely so soon?), then you, at seventy-five, will be writing another letter like this one. You will be undergoing another experience similar to the one you're going through now. And making the same decision, of course.

Why not? You'll be the same person again.

Time and again, to preserve this secret until Man is ready for it.

How often will you again sit at a desk like this one, thinking the thoughts you are thinking now, feeling the grief you now feel?

There is a click at the door and you know that the time lock has opened, that you are now free to leave this room, free to start a new life for yourself in place of the one you have already lived and lost.

But you are in no hurry now to walk directly through that door.

You sit there, staring straight ahead of you blindly, seeing in your mind's eye the vista of a set of facing mirrors, like those in an old-fas.h.i.+oned barber shop, reflecting the same thing over and over again, diminis.h.i.+ng into far distance.

WEAK ON SQUARE ROOTS.

by Russell Burton

Does your wife call you Pumpkinhead? Well, maybe it's not an insult; it might be a pet name. Ah--but whose pet name?

As his coach sped through dusk-darkened Jersey meadows, Ronald Lovegear, fourteen years with Allied Electronix, embraced his burden with both arms, silently cursing the engineer who was deliberately rocking the train. In his thin chest he nursed the conviction that someday there would be an intelligent robot at the throttle of the 5:10 to Philadelphia.

He carefully moved one hand and took a notebook from his pocket. That would be a good thing to mention at the office next Monday.

Again he congratulated himself for having induced his superiors to let him take home the company's most highly developed mechanism to date. He had already forgiven himself for the little white lie that morning.

"Pascal," he had told them, "is a little weak on square roots." That had done it!

Old Hardwick would never permit an Allied computer to hit the market that was not the absolute master of square roots. If Lovegear wanted to work on Pascal on his own time it was fine with the boss.

Ronald Lovegear consulted his watch. He wondered if his wife would be on time. He had told Corinne twice over the phone to bring the station wagon to meet him. But she had been so forgetful lately. It was probably the new house; six rooms to keep up without a maid was quite a ch.o.r.e. His pale eyes blinked. He had a few ideas along that line too. He smiled and gave the crate a gentle pat.

Corinne was at the station, and she had brought the station wagon. Lovegear managed to get the crate to the stairs of the coach where he consented to the a.s.sistance of a porter.

"It's not really heavy," he told Corinne as he and the porter waddled through the crowd. "Actually only 57 pounds, four ounces. Aluminum casing, you know ..."

"No, I didn't ..." began Corinne.

"But it's delicate," he continued. "If I should drop this ..." He shuddered.

After the crate had been placed lengthwise in the rear of the station wagon, Corinne watched Ronald tuck a blanket around it.

"It's not very cold, Ronald."

"I don't want it to get bounced around," he said. "Now, please, Corinne, do drive carefully." Not until she had driven half a block did he kiss her on the cheek. Then he glanced anxiously over his shoulder at the rear seat. Once he thought Corinne hit a rut that could have been avoided.

Long after Corinne had retired that night she heard Ronald pounding with a bra.s.s hammer down in his den. At first she had insisted he take the crate out to his workshop. He looked at her with scientific aloofness and asked if she had the slightest conception of what "this is worth?" She hadn't, and she went to bed. It was only another one of his gestures which was responsible for these weird dreams. That night she dreamed Ronald brought home a giant octopus which insisted on doing the dishes for her. In the morning she woke up feeling unwanted.

Downstairs Ronald had already put on the coffee. He was wearing his robe and the pinched greyness of his face told Corinne he had been up half the night. He poured coffee for her, smiling wanly. "If I have any commitments today, Corinne, will you please see that they are taken care of?"

"But you were supposed to get the wallpaper for the guest room...."

"I know, I know, dear. But time is so short. They might want Pascal back any day. For the next week or two I shall want to devote most of my time ..."

"Pascal?"

"Yes. The machine--the computer." He smiled at her ignorance. "We usually name the expensive jobs. You see, a computer of this nature is really the heart and soul of the mechanical man we will construct."

Corinne didn't see, but in a few minutes she strolled toward the den, balancing her coffee in both hands. With one elbow she eased the door open. There it was: an innocent polished cabinet reaching up to her shoulders. Ronald had removed one of the plates from its side and she peeped into the section where the heart and soul might be located. She saw only an unanatomical array of vacuum tubes and electrical relays.

She felt Ronald at her back. "It looks like the inside of a juke box," she said.

He beamed. "The same relay systems used in the simple juke box are incorporated in a computer." He placed one hand lovingly on the top of the cabinet.

"But, Ronald--it doesn't even resemble a--a mechanical man?"

"That's because it doesn't have any appendages as yet. You know, arms and legs. That's a relatively simple adjustment." He winked at Corinne with a great air of complicity. "And I have some excellent ideas along that line. Now, run along, because I'll be busy most of the day."

Corinne ran along. She spent most of the day shopping for week-end necessities. On an irrational last-minute impulse--perhaps an unconscious surrender to the machine age--she dug in the grocery deep freeze and brought out a couple of purple steaks.

That evening she had to call Ronald three times for dinner, and when he came out of the den she noticed that he closed the door the way one does upon a small child. He chattered about inconsequential matters all through dinner. Corinne knew that his work was going smoothly. A few minutes later she was to know how smoothly.

It started when she began to put on her ap.r.o.n to do the dishes. "Let that go for now, dear," Ronald said, taking the ap.r.o.n from her. He went into the den, returning with a small black box covered with push b.u.t.tons. "Now observe carefully," he said, his voice pitched high.

He pushed one of the b.u.t.tons, waited a second with his ear c.o.c.ked toward the den, then pushed another.

Corinne heard the turning of metal against metal, and she slowly turned her head.

"Oh!" She suppressed a shriek, clutching Ronald's arm so tightly he almost dropped the control box.

Pascal was walking under his own effort, considerably taller now with the round, aluminum legs Ronald had given him. Two metal arms also hung at the sides of the cabinet. One of these rose stiffly, as though for balance. Corinne's mouth opened as she watched the creature jerk awkwardly across the living room.

"Oh, Ronald! The fishbowl!"

Ronald stabbed knowingly at several b.u.t.tons.

Pascal pivoted toward them, but not before his right arm swung out and, almost contemptuously, brushed the fishbowl to the floor.

Corinne closed her eyes at the crash. Then she scooped up several little golden bodies and rushed for the kitchen. When she returned Ronald was picking up pieces of gla.s.s and dabbing at the pool of water with one of her bathroom towels. Pascal, magnificently aloof, was standing in the center of the mess.

"I'm sorry." Ronald looked up. "It was my fault. I got confused on the b.u.t.tons."

But Corinne's glances toward the rigid Pascal held no indictment. She was only mystified. There was something wrong here.

"But Ronald, he's so ugly without a head. I thought that all robots--"

"Oh, no," he explained, "we would put heads on them for display purposes only. Admittedly that captures the imagination of the public. That little adapter shaft at the top could be the neck, of course...."

He waved Corinne aside and continued his experiments with the home-made robot. Pascal moved in controlled spasms around the living room. Once, he walked just a little too close to the floor-length window--and Corinne stood up nervously. But Ronald apparently had mastered the little black box.

With complete confidence Corinne went into the kitchen to do the dishes. Not until she was elbow deep in suds did she recall her dreams about the octopus. She looked over her shoulder, and the curious, unwanted feeling came again.

The following afternoon--after Ronald had cancelled their Sunday drive into the country--Pascal, with constant exhortations by Ronald at the black box, succeeded in vacuum cleaning the entire living room. Ronald was ecstatic.
