"But," the psychiatrist pointed out, "you don't know which isotope blew up."

"Nor care," Harper supplemented. "Maybe it was both, taken together. But we will know-this business is cracked now; we'll soon have it open." He gazed happily around at the wreckage.

In spite of Superintendent King's anxiety, Lentz refused to be hurried in pa.s.sing judgment on the situation. Consequently, when be did present himself at King's office, and announced that he was ready to report, King was pleasantly surprised as well as relieved. "Well, I'm delighted," he said. "Sit down, doctor, sit down. Have a cigar. What do we do about it?"

But Lentz stuck to his perennial cigarette, and refused to be hurried. "I must have some information first: how important," he demanded, "is the power from your plant?"

King understood the implication at once. "If you are thinking about shutting down - the plant for more than a limited period, it can't be done."

"Why not? If the figures supplied me are correct, your power output is less than thirteen percent of the total power used in the country."

"Yes, that is true, but we also supply another thirteen percent second hand through the plutonium we breed here-and you haven't a.n.a.lyzed the items that make up the balance. A lot of it is domestic power which householders get from sunscreens located on their roofs. Another big slice is power for the moving roadways-that's sunpower again. The portion we provide here directly or indirectly is the main power source for most of the heavy industries-steel, plastics, lithics, all kinds of manufacturing and processing.

You might as well cut the heart out of a man-"

"But the food industry isn't basically dependent on you?" Lentz persisted.

"No ... Food isn't basically a power industry though we do supply a certain percentage of the power used in processing. I see your point, and will go on, concede that transportation, that is to say, distribution food, could get along without us. But good heavens, Doctor, you can't stop atomic power without causing the biggest panic this country has ever seen. It's the keystone our whole industrial system."

"The country has lived through panics before, and we got past the oil shortage safely."

"Yes because sunpower and atomic power had to take the place of oil. You don't realize what would mean, Doctor. It would be worse than a war; in system like ours, one thing depends on another. If you cut off the heavy industries all at once, everything else stops too."

"Nevertheless, you had better dump the pile." The uranium in the pile was molten, its temperature bell greater than twenty-four hundred degrees centigrade. The pile could be dumped into a group of small containers when it was desired to shut it down. The ma.s.s into one container would be too small to maintain progressive atomic disintegration.

Icing glanced involuntarily at the gla.s.s-enclosed relay mounted on his office wall, by which he, as well as the engineer on duty, could dump the pile, if need be. "But ~ couldn't do that ... or rather, if I did, the plant wouldn't stay shut down. The directors would simply replace me with someone who would operate it."

"You're right, of course." Lentz silently considered the situation for some time, then said, "Superintendent, will you order a car to fly me back to Chicago?"

"You're going, doctor?"

"Yes." He took the cigarette holder from his face, and, for once, the smile of Olympian detachment was gone completely. His entire manner was sober, even tragic.

"Short of shutting down the plant, there is no solution to your problem-none whatsoever!"

"I owe you a full explanation," he continued, presently.

"You are confronted here with recurring instances of situational psychoneurosis. Roughly, the symptoms manifest themselves as anxiety neurosis, or some form of hysteria.

The partial amnesia of your secretary, Steinke, is a good example of the latter. He might be cured with shock technique, but it would hardly be a kindness, as he has achieved a stable adjustment which puts him beyond the reach of the strain he could not stand.

"That other young fellow, Harper, whose blowup was the immediate cause of you sending for me, is an anxiety case. When the cause of the anxiety was eliminated from his matrix, he at once regained full sanity. But keep a close watch on his friend, Erickson- "However, it is the cause, and prevention, of situational psychoneurosis we are concerned with here, rather than the forms in which it is manifested. In plain language, psychoneurosis situational simply refers to the common fact that, if you put a man in a situation that worries him more than he can stand, in time he blows up, one way or another.

"That is precisely the situation here. You take sensitive, intelligent young men, impress them with the fact that a single slip on their part, or even some fortuitous circ.u.mstance beyond their control, will result in the death of G.o.d knows how many other people, and then expect them to remain sane. It's ridiculous-impossible!"

"But good heavens, doctor!-there must be some answer- There must!" He got up and paced around the room. Lentz noted, with pity, that King himself was riding the ragged edge of the very condition they were discussing.

"No," he said slowly. "No ... let me explain. You don't dare entrust control to less sensitive, less socially conscious men. You might as well turn the controls over to a mindless idiot. And to psychoneurosis situational there are but two cures. The first obtains when the psychosis results from a misevaluation of environment. That cure calls for semantic readjustment. One a.s.sists the patient to evaluate correctly his environment. The worry disappears because there never was a real reason for worry in the situation itself, but simply in the wrong meaning the patient's mind had a.s.signed to it.

"The second case is when the patient has correctly evaluated the situation, and rightly finds in it cause for extreme worry. His worry is perfectly sane and proper, but he cannot stand up under it indefinitely; it drives him crazy. The only possible cure is to change the situation. I have stayed here long enough to a.s.sure myself that such is the condition here. You engineers have correctly evaluated the public danger of this thing, and it will, with dreadful certainty, drive all of you crazy!

"The only possible solution is to dump the pile-and leave it dumped."

King had continued his nervous pacing of the floor, as if the walls of the room itself were the cage of his dilemma. Now he stopped and appealed once more to the psychiatrist. "Isn't there anything I can do?"

"Nothing to cure. To alleviate-well, possibly."

"How?"

"Situational psychosis results from adrenalin exhaustion. When a man is placed under a nervous strain, his adrenal glands increase their secretion to help compensate for the strain. If the strain is too great and lasts too long, the adrenals aren't equal to the task, and he cracks. That is what you have here.

Adrenalin therapy might stave of a mental breakdown, but it most a.s.suredly would hasten a physical breakdown. But that would be safer from a viewpoint of public welfare-even though it a.s.sumes that physicists are expendable!

"Another thing occurs to me: If you selected any new watch engineers from the membership of churches that practice the confessional, it would increase the length of their usefulness."

King was plainly surprised. "I don't follow you."

"The patient unloads most of his worry on his confessor, who is not himself actually confronted by the situation, and can stand it. That is simply an ameliorative, however. I am convinced that in this situation, eventual insanity is inevitable. But there is a lot of good sense in the confessional," he mused. "It fills a basic human heed. I think that is why the early psychoa.n.a.lysts were so surprisingly successful, for all their limited knowledge." He fell silent for a while, then added, "If you will be so kind as to order a stratocab for me-"

"You've nothing more to suggest?'

"No. You had better turn your psychological staff loose on means of alleviation; they're able men, all of them."

King pressed a switch, and spoke briefly to Steinke. Turning back to Lentz, he said, "You'll wait here until your car is ready?"

Lentz judged correctly that King desired it, and agreed.

Presently the tube delivery on King's desk went "Ping!"

The superintendent removed a small white pasteboard, a calling card. He studied it with surprise and pa.s.sed it over to Lentz. "I can't imagine why he should be calling on me," he observed, and added, "Would you like to meet him?"

Lentz read: THOMAS P. HARRINGTON.

Captain (Mathematics) United States Navy Director U.S. Naval Observatory

"But I do know him," he said. "I'd be very pleased to see him."

Harrington was a man with something on his mind. He seemed relieved when Steinke had finished ushering him in and had returned to the outer office. He commenced to speak at once, turning to Lentz, who was nearer to him than King.

"You're King? Why, Doctor Lentz! What are you doing here?"

"Visiting," answered Lentz, accurately - but incompletely, as he shook hands. "This is Superintendent King over here. Superintendent King-Captain Harrington."

"How do you do, Captain-it's a pleasure to have you here."

"It's an honor to be here sir."

"Sit down?"

"Thanks." He accepted a chair, and laid a briefcase at a corner of King's desk. "Superintendent, you are ent.i.tle to an explanation as to why I have broken in on you Ilk this-"

"Glad to have you." In fact, the routine of formal politeness was an anodyne to King's frayed nerves.

"That's kind of you, but that secretary chap, the one that brought me in here, would it be too much to as for you to tell him to forget my name? I know it seem strange-"

"Not at all." King was mystified, but willing to grab any reasonable request of a distinguished colleague in science. He summoned Steinke to the interoffice visiphone and gave him his orders.

Lentz stood up, and indicated that he was about to leave. He caught Harrington's eye. "I think you want private palaver, Captain."

King looked from Harrington to Lentz, and back at Harrington. The astronomer showed momentary indecision, then protested, "I have no objection at all myself it's up to Doctor King. As a matter of fact,"

he added," might be a very good thing if you did sit in on it."

"I don't know what it is, Captain," observed Kin~ "that you want to see me about, but Doctor Lentz is a ready here in a confidential capacity."

"Good! Then that's settled .. I'll get right down I business. Doctor King, you know Destry's mechanics infinitesimals?"

"Naturally." Lentz c.o.c.ked a brow at King, who chose to ignore it.

"Yes, of course. Do you remember - theorem six, an the transformation between equations thirteen and fourteen?"

"I think so, but I'd want to see them." King got up and went over to a bookcase. Harrington stayed him with a hand.

"Don't bother. I have them here." He hauled out a key, unlocked his briefcase, and drew out a large, much thumbed, loose-leaf notebook. "Here. You, too, Doctor Lentz. Are you familiar with this development?"

Lentz nodded. "I've had occasion to look into them."

"Good-I think it's agreed that the step between thirteen and fourteen is the key to the whole matter.

Now the change from thirteen to fourteen looks perfectly valid and would be, in some fields. But suppose we expand it to show every possible phase of the matter, every link in the chain of reasoning."

He turned a page, and showed them the same two equations broken down into nine intermediate equations. He placed a finger under an a.s.sociated group of mathematical symbols. "Do you see that? Do you see what that implies?" He peered anxiously at their faces.

King studied it, his lips moving. "Yes. .. . I -believe I do see. 'Odd... I never looked at it just that way before- yet I've studied those equations until I've dreamed about them." He turned to Lentz. "Do you agree, Doctor?"

Lentz nodded slowly. "I believe so ... Yes, I think I may say so."

Harrington should have been pleased; he wasn't. "I had hoped you could tell me I was wrong," he said, almost petulantly, "but I'm afraid there is no further doubt about it. Doctor Destry included an a.s.sumption valid in molar physics, but for which we have absolutely no a.s.surance in atomic physics. I suppose you realize what this means to you, Doctor King?"

King's voice was a dry whisper. "Yes," he said, "yes it means that if the Big Bomb out there ever blows up, we must a.s.sume that it will all go up all at once, rather than the way Destry predicted ... and G.o.d help the human race!"

Captain Harrington cleared his throat to break the silence that followed. "Superintendent," he said, "I would not have ventured to call had it been simply a matter of disagreement as to interpretation of theoretical predictions-"

"You have something more to go on?"

"Yes, and no. Probably you gentlemen think of the Naval Observatory as being exclusively preoccupied with ephemeredes and tide tables. In a way you would be right-but we still have some time to devote to research as long as it doesn't cut into the appropriation. My special interest has always been lunar theory.

"I don't mean lunar ballistics," he continued, "I mean the much more interesting problem of its origin and history, the problem the younger Darwin struggled with, as well as my Ill.u.s.trious predecessor, Captain T. J. J. See. I think that it is obvious that any theory of lunar origin and history must take into account the surface features of the moon-especially the mountains, the craters, that mark its face so prominently."

He paused momentarily, and Superintendent King put in, "Just a minute, Captain-I may be stupid, or perhaps I missed something, but-is there a connection between what we were discussing before and lunar theory?"

"Bear with me for a few moments, Doctor King," Harrington apologized; "there is a connection-at least, I'm afraid there is a connection-but I would rather present my points in their proper order before making my conclusions." They granted him an alert silence; he went on: "Although we are in the habit of referring to the 'craters' of the moon, we know they are not volcanic craters. Superficially, they follow none of the rules of terrestrial volcanoes in appearance or distribution, but when Rutter came out in 952 with his monograph on the dynamics of vulcanology, he proved rather conclusively that the lunar craters could not be caused by anything that we know as volcanic action.

"That left the bombardment theory as the simplest hypothesis. It looks good, on the face of it, and a few minutes spent throwing pebbles in to a patch of mud will convince anyone that the lunar craters could have been formed by falling meteors.

"But there are difficulties. If the moon was struck so repeatedly, why not the earth? It hardly seems necessary to mention that the earth's atmosphere would be no protection against ma.s.ses big enough to form craters like Endymion, or Plato. And if they fell after the moon was a dead world while the earth was still young enough to change its face and erase the marks of bombardment, why did the meteors avoid so nearly completely the dry basins we call the seas?

"I want to cut this short; you'll find the data and the mathematical investigations from the data here in my notes. There is one other major objection to the meteor bombardment theory: the great rays that spread from Tycho across almost the entire surface of the moon. It makes the moon look like a crystal ball that had been struck with a hammer, and impact from - outside seems evident, but there are difficulties. The striking ma.s.s, our hypothetical meteor, must have been smaller than the present crater of Tycho, but it must have the ma.s.s and speed to crack an entire planet."

"Work it out for yourself-you must either postulate a chunk out of the core of a dwarf star, or speeds such as we have never observed within the system. It's conceivable but a far-fetched explanation"

He turned to King. "Doctor, does anything occur to you that might account for a phenomenon like Tycho?"

The Superintendent grasped the arms of his chair, then glanced at his palms. He fumbled for a handkerchief, and wiped them. "Go ahead," he said, almost inaudibly.

"Very well then-" Harrington drew out of his briefcase a large photograph of the moon-a beautiful full-moon portrait made at Lick. "I want you to imagine the moon as she might have been sometime in the past. The dark areas we call the 'Seas' are actual oceans. It has an atmosphere, perhaps a heavier gas than oxygen and nitrogen, but an active gas, capable of supporting some conceivable form of life.

"For this is an inhabited planet, inhabited by intelligent beings, beings capable of discovering atomic power and exploiting it!"

He pointed out on the photograph, near the southern limb, the lime-white circle of Tycho, with its shining, incredible, thousand-mile-long rays spreading, thrusting, jutting out from it. "Here ... here at Tycho was located their main atomic plant." He moved his finger to a point near the equator, and somewhat east of meridian-the point where three great dark areas merged, Mare Nubium, Mare Imbriwn, Ocea.n.u.s Procellarum-and picked out two bright splotches surrounded also by rays, but shorter, less distinct, and wavy. "And here at Copernicus and at Kepler, on islands at the middle of a great ocean, were secondary power stations."

He paused, and interpolated soberly, "Perhaps they knew the danger they ran, but wanted power so badly that they were willing to gamble the life of their race. Perhaps they were ignorant of the ruinous possibilities of their little machines, or perhaps their mathematicians a.s.sured them that it could not happen.

"But we will never know ... no one can ever know. For it blew up, and killed them-and it killed their planet.

"It whisked off the ga.s.sy envelope and blew it into outer s.p.a.ce. It may even have set up a chain reaction, in that atmosphere. It blasted great chunks of the planet's crust Perhaps some of that escaped completely, too, but all that did not reach the speed of escape fell back down in time and splashed great ring-shaped craters in the land.

"The oceans cushioned the shock; only the more ma.s.sive fragments formed craters through the water. Perhaps some life still remained in those ocean depths. If so, it was doomed to die-for the water, unprotected by atmospheric pressure, could not remain liquid and must inevitably escape lit time to outer s.p.a.ce. Its life blood drained away. The planet was dead-dead by suicide!

He met the grave eyes of his two silent listeners with an expression almost of appeal. "Gentlemen-this is only a theory I realize ... only a theory, a dream, a nightmare- But it has kept me awake so many nights that I had to come tell you about it, and see if you saw it the same way I do.

As for the mechanics of it, it's all in there, in my notes. You can check it-and I pray that you find some error! But it is the only lunar theory I have examined which included all of the known data, and accounted for all of them."

He appeared to have finished; Lentz spoke up. "Suppose, Captain, suppose we check your mathematics and find no flaw-what then?"

Harrington flung out his hands. "That's what I came here to find out!"

Although Lentz had asked the question, Harrington directed the appeal to King. The superintendent looked up; his eyes met the astronomer's, wavered, and dropped again. "There's nothing to be done," he said dully, "nothing at all."

Harrington stared at him in open amazement. "But good G.o.d, man!" he burst out. "Don't you see it?

That pile has got to be disa.s.sembled at once!"

"Take it easy, Captain." Lentz's calm voice was a spray of cold water. "And don't be too harsh on poor King, this worries him even more than it does you. What he means is this; we're not faced with a problem in physics, but with a political and economic situation. Let's put it this way: King can no more dump his plant than a peasant with a vineyard on the slopes of Mount Vesuvius can abandon his holdings and pauperize his family simply because there will be an eruption someday.

"King doesn't own that plant out there; he's only the custodian. If he dumps it against the wishes of the legal owners, they'll simply oust him and put in someone more amenable. No, we have to convince the owners."
