"Thanks," said Dr. Frank as the door closed behind the Navy man.
As soon as it closed, President Cannon struggled to get up.
"Don't try it, kid," the doctor said, "those muscles are paralyzed, even if you aren't sick. Here, let me help you."
"How did it come off?" Cannon asked as his brother propped him up.
"Perfectly. No one doubts that it's a stroke. Now what?"
"Give me a cigarette."
"All right, but watch it. Use your right hand, and smoke with the right side of your mouth. Here." The doctor lit a cigarette and handed it to his brother. "Now, what's the next step?"
"The next step is to tell Matthew Fisher," said the President.
* * * * *
Dr. Frank Cannon scowled. "Why? Why not just go through with the thing and let him be fooled along with the rest? It seems to me he'd be ... well, more secure in his own position if he didn't know."
"No." The President hunched himself up on his pillows. "Can't you raise the head of this bed?"
Dr. Frank touched a button on the bedside panel, and the upper portion of the bed rose smoothly at an angle. "Better?"
"Fine. Much better."
"You were saying--"
"Yeah. About Matt Fisher. He has to know. He'll guess eventually, in the next four years, anyway--unless I hide away somewhere. And I have no intention of doing that.
"Oh, I'm not trying to show Matt what a great guy I am, Frank. You know better than that, and so will he. But Matt will have to have all the facts at hand, if he's to do his job right, and it seems to me that this is a pretty important fact. What do you say, Frank?"
The doctor nodded slowly. "I think you know more about the situation than I do. And I trust your judgment, kid. And Matt's, too, I guess."
"No." President Cannon's voice was firm as he looked at his brother with one bright eye. "Don't trust Matt's judgment, because he doesn't have any."
Dr. Frank looked astonished. "Then what--?" He stopped.
"Matthew Fisher," said President Cannon authoritatively, "doesn't need judgment any more than you need instinct. No more so, and no less. I said he doesn't have any judgment, but that's not exactly true. He has it, but he only uses it for routine work, just as you or I use instinct. We can override our instinctive reactions when we have to. Matt can override his judgment when he has to.
"I don't pretend to know how Fisher's mind works. If I did, I wouldn't be doing this. But I do know that Matt Fisher--by some mental process I can't even fathom--almost invariably knows the right thing to do, and he knows it without using judgment."
"And you're still convinced that this is the only way out?" Dr. Frank asked. "Couldn't you stay in office and let him run things under cover?"
"We discussed all this months ago, Frank," Cannon said wearily. "My reasons remain the same. Matt couldn't possibly operate efficiently if he had to go through me every time. And I am human, too; I'd have a tendency to impose my own judgment on his decisions.
"No, Frank; this is the only way it can work. This country needs Matthew Fisher as President, but he could never have been elected. Now I've done my job; now it's time for me to get out of the way and turn the Presidency over to a man who can handle the office far better than any other man I know."
"You make him sound like some sort of superman," said Dr. Frank with a wry grin.
"Hell," said President Cannon, "you don't think I'd turn this job over to anything less, do you?" He chuckled. "Call him in, will you?"

HANGING BY A THREAD
By Randall Garrett
It's seldom that the fate of a shipful of men literally hangs by a thread--but it's also seldom that a device, every part of which has been thoroughly tested, won't work....
Jayjay Kelvin was sitting in the lounge of the interplanetary cargo vessel Persephone, his feet propped up on the low table in front of the couch, and his attention focused almost totally on the small book he was reading. The lounge itself was cozily small; the Persephone had not been designed as a passenger vessel, and the two passengers she was carrying at the time had been taken on as an accommodation rather than as a money-making proposition. On the other hand, the Persephone and other ships like her were the only method of getting to where Jayjay Kelvin wanted to go; there were no regular passenger runs to Pluto. It's hardly the vacation spot of the Solar System.
On the other side of the table, Jeffry Hull was working industriously with pencil and paper. Jayjay kept his nose buried in his book--not because he was deliberately slighting Hull, but because he was genuinely interested in the book.
"Now wait," said Masterson, looking thoughtfully at the footprints on the floor of the cabin where Jed Hooker had died. "Jest take another look at these prints, Charlie. Silver Bill Greer couldn't have got much more than his big toe into boots that small! Somethin' tells me the Pecos Kid has...."
"... Traveled nearly two billion miles since then," said Hull.
Jayjay lifted his head from his book. "What?" He blinked. "I'm sorry; I wasn't listening. What did you say?"
The younger man was still grinning triumphantly. "I said: We are approaching turnover, and, according to my figures, nine days of acceleration at one standard gee will give us a velocity of seventeen million, five hundred and fifty miles per hour, and we have covered a distance of nearly two billion miles." Then he added: "That is, if I remembered my formulas correctly."
Jayjay Kelvin looked thoughtfully at the ceiling while he ran through the figures in his head. "Something like that. It's the right order of magnitude, anyway."
Hull looked a little miffed. "What answer did you get?"
"A little less than eight times ten to the third kilometers per second. I was just figuring roughly."
Hull scribbled hastily, then smiled again. "Eighteen million miles an hour, that would be. My memory's better than I thought at first. I'm glad I didn't have to figure the time; doing square roots is a process I've forgotten."
That was understandable, Jayjay thought. Hull was working for his doctorate in sociology, and there certainly wasn't much necessity for a sociologist to remember his freshman physics, much less his high-school math.
Still, it was somewhat of a relief to find that Hull was interested in something besides the "sociological reactions of Man in space". The boy had spent six months in the mining cities in the Asteroid Belt, and another six investigating the Jovian chemical synthesis planes and their attendant cities. Now he was heading out to spend a few more months observing the "sociological organization Gestalt" of the men and women who worked at the toughest job in the System--taking the heavy metals from the particularly dense sphere of Pluto.
Hull began scribbling on his paper again, evidently lost in the joys of elementary physics, so Jayjay Kelvin went back to his book.
He had just read three words when Hull said: "Mr. Kelvin, do you mind if I ask a question?"
Jayjay looked up from his book and saw that Jeffry Hull had reverted to his role of the earnest young sociologist. Ah, well. "As I've told you before, Mr. Hull, questions do not offend me, but I can't guarantee that the answers won't offend you."
"Yes; of course," Hull said in his best investigatory manner. "I appreciate that. It's just that ... well, I have trained myself to notice small things. The little details that are sometimes so important in sociological investigations. Not, you understand, as an attempt to pry into the private life of the individual, but to round out the overall picture."
Jayjay nodded politely. To his quixotic and pixie-like mind, the term overall picture conjured up the vision of a large and carefully detailed painting of a pair of dirty overalls, but he kept the smile off his face and merely said: "I understand."
"Well, I've noticed that you're quite an avid reader. That isn't unusual in a successf
ul businessman, of course; one doesn't become a successful businessman unless one has a thirst for knowledge."
"Hm-m-m," said Jayjay.
"But," Hull continued earnestly, "I noticed that you've read most of the ... uh ... historical romances in the library...."
"You mean Westerns," Jayjay corrected quietly.
"Uh ... yes. But you don't seem to be interested in the modern adventure fiction. May I ask why?"
"Sure." Jayjay found himself becoming irrationally irritated with Hull. He knew that the young sociologist had nothing to do with his own irritation, so he kept the remarks as impersonal as possible. "In the first place, you, as a sociologist, should know what market most fiction is written for."
"Why ... uh ... for people who want to relax and--"
"Yes," Jayjay cut in. "But what kind? The boys on Pluto? The asteroid slicers? No. There are four billion people on Earth and less than five million in space. The market is Earth.
"Also, most writers have never been any farther off the surface of Earth than the few miles up that an intercontinental cruiser takes them.
"And yet, the modern 'adventure' novel invariably takes place in space.
"I can read Westerns because I neither know nor care what the Old American West was really like. I can sit back and sink into the never-never land that the Western tells about and enjoy myself because I am not forced to compare it with reality.
"But a 'space novel' written by an Earthside hugger is almost as much a never-never land, and I have to keep comparing it with what is actually going on around me. And it irritates me."
"But, aren't some of them pretty well researched?" Hull asked.
"Obviously, you haven't read many of them," Jayjay said. "Sure, some of them are well researched. Say one half of one per cent, to be liberal. The rest don't know what they're talking about!"
"But--"
"For instance," Jayjay continued heatedly, "you take a look at every blasted one of them that has anything to do with a spacecraft having trouble. They have to have an accident in space in order to disable the spaceship so that the hairy-chested hero can show what a great guy he is. So what does the writer do? He has the ship hit by a meteor! A meteor!"
Hull thought that over for a second. "Well," he said tentatively, "a ship could get hit by a meteor, couldn't it?"
Jayjay closed his eyes in exasperation. "Of course it could! And an air-ship can run into a ruby-throated hummingbird, too. But how often does it happen?
"Look: We're hitting it up at about one-fortieth of the velocity of light right now. What do you think would happen if we got hit by a meteor? We'd be gone before we knew what had happened.
"Why doesn't it happen? Because we can spot any meteor big enough to hurt us long before it contacts us, and we can dodge it or blast it out of the way, depending on the size.
"You've seen the outer hull of this ship. It's an inch thick shell of plastic, supported a hundred feet away from the steel hull by long booms. Anything small enough to get by the detectors will be small enough to burn itself out on that hull before it reaches the ship. The--"

Jayjay Kelvin was not ordinarily a man to make long speeches, especially when he knew he was telling someone something that they already knew. But this time, he was beating one of his favorite drums, and he went on with his tirade in a fine flush of fury.
Alas ... poor Jayjay.
Actually, Jayjay Kelvin can't be blamed for his attitude. All he was saying was that it was highly improbable that a spaceship would be hit by a meteor. In one way, he was perfectly right, and, in another, he was dead wrong.
How small must a piece of matter be before it is no longer a meteor?
Fortunately, the big hunks rarely travel at more than about two times ten to the sixth centimeters per second, relative to Sol, in the Solar System. But there are little meteors--very tiny ones--that come in, hell-bent-for-leather, at a shade less than the velocity of light. They're called cosmic rays, but they're not radiation in the strict sense of the word. A stripped hydrogen atom, weighing on the order of three point three times ten to the minus twenty-second grams, rest mass, can come galumping along at a velocity so close to that of light that the kinetic energy is something colossal for so small a particle. Protons with a kinetic energy of ten to the nineteenth electron volts, while statistically rare, are not unusual.
Now, ten million million million electron volts may be a wee bit meaningless to the average man, so let's look at it from another angle.
Consider. According to the well-known formula E = mc^2, a single gram of matter, if converted completely into energy, would yield some nine hundred million million million ergs of energy. An atomic bomb yields only a fraction of that energy, since only a small percentage of the mass is converted into energy.
If all of the mass of an atomic bomb were converted into energy, the test in Alamogordo, New Mexico, 'way back in 1945, would probably have been the last such test on Earth; there wouldn't have been anyone around to make a second test.
So what does this have to do with cosmic ray particle? Well, if that atomic bomb had been moving at the velocity with which our ten-to-the-nineteenth-electron-volts proton is moving, it could have been made of sand instead of U^235. It would have produced ten thousand million times as much energy as the total disintegration of the rest mass would have produced!
Kinetic energy, my children, has a great deal more potential than atomic energy.
But we digress.
What has all this to do with Jayjay Kelvin?
If Jayjay had been a detective story addict instead of a Western story addict, he would have heard of the HIBK or "Had I But Known" school of detective writing. You know: "Had I But Known that, at that moment, in the dismal depths of a secret underground meeting place, the evil Chuman-Fu was plotting...."
If Jayjay Kelvin had known what was going on a few million miles away from the Pluto-bound Persephone, he would have kept his mouth shut.
* * * * *
The cargo-ship Mordred was carrying a cargo of heavy metals sunward. In her hold were tightly-packed ingots of osmium-iridium-platinum alloy, gold-copper-silver-mercury alloy, and small percentages of other of the heavy metals. The cargo was to be taken to the Asteroid Belt for purification and then shipped Earthward for final disposition. The fact that silver had replaced copper for electrical purposes on Earth was due to the heavy-metals industry on Pluto. Because of Pluto, the American silver bloc had been broken at last.
The Mordred was approaching turnover.
Now, with a gravito-inertial drive, there is really no need to turn a ship over end-for-end as she approaches the mid-point of her trajectory. Since there is no rocket jet to worry about, all that is really necessary is to put the engine in reverse. In fact, the patrol ships of the Interplanetary Police do just that.
But the IP has been trained to take up to five standard gees in an end-to-end flip, and the ships are built to take the stress in both directions. An ordinary cargo ship finds it a lot easier to simply flip the ship over; that way, the stresses remain the same, and the ceiling-floor relationship is constant.
The Mordred had been having a little trouble with her Number Three drive engine, so the drive was cut off at turnover, while the engineer replaced a worn bearing. At the same time, the maintenance officer decided he'd take a look at the meteor-bumper--the plastic outer hull. Since the ship was in free fall, all he had to do was pull himself along one of the beams that supported the meteor-bumper away from the main hull. The end of one of the beams had cracked a part of the bumper hull--fatigue from stress, nothing more, but the hull might as well be patched while the drive was off.
It was a one-man job; the plastic was dense, but under null-gee conditions it was easy to maneuver. The maintenance officer repaired the slight crack easily, wiped the sticky pre-polymer from the fingers of his spacesuit gloves, and tossed the gooey rag off into space. Then he pushed himself back across the vacuum that separated the outer hull
from the inner, entered the air lock, and reported that the job was finished. Five minutes later, the Mordred began decelerating toward the distant Asteroid Belt.
Forget the Mordred. The ship is no longer important. Keep your eyes on that rag. It's a flimsy thing, composed of absorbent plastic and gooed up with a little unpolymerized resin, weighing about fifty grams. It is apparently floating harmlessly in space, just beyond the orbit of Uranus, looking as innocuous as a rag can look. But it is moving sunward at eight hundred million centimeters per second.
* * * * *
The Persephone was approaching turnover. The ship's engineer reported that the engines were humming along smoothly, so there was no need to shut them off; the ship would simply flip over as she ran, making her path a slightly skewed, elongated S-curve--a sort of orbital hiccup.
Except that she never quite made it through the hiccup. The ship was almost perpendicular to her line of flight when she was sideswiped.
Her meteor detectors hadn't failed; they were still functioning perfectly. But meteor detectors are built to look for solid chunks of metal and rock--not thin, porous bits of cloth.
The rag had traveled a good many millions of miles since it had been cast overboard; it was moving sunward with almost the same velocity with which the Persephone was moving Plutowards. The combined velocities were such that, if it had hit the Persephone dead on, it would have delivered close to seventeen thousand kilowatt-hours of energy in one grand burst of incandescence.
Fortunately, the tip of the rag merely gave the ship a slap on the tail as it passed. The plastic meteor-bumper wasn't built to take that sort of thing. The plastic became an expanding cloud of furiously incandescent gas in a small fraction of a second, but the velocity of that bit of rag was so great that the gas acted as a solid block of superheated fury as it leaped across the hundred feet of vacuum which separated the bumper hull from the inner hull.
A rocket-driven missile carrying a shaped-charge warhead weighing several hundred pounds might have done almost as much damage.
