The Best of E E 'Doc' Smith

"Sure. Then, having everything set for zero time, and assuming that the activity is somewhere near my postulated value... ."

  "Assume that it isn't-it probably won't be"" the Chief grunted.

  "I accelerate or decelerate-"

  "Solving new equations all the while?"

  "Sure-don't interrupt so-until at zero time the activity, extrapolated to zero time, matches one of my bombs. I cut that bomb loose, shoot myself off in a sharp curve, and Z-W-E-E-E-T-POWIE! She's out!" With an expressive, sweeping gesture.

  "You hope," the Lensman was frankly dubious. "And there you are" right in the middle of that explosive, with two duodec bombs outside your armor-or just inside your flitter."

  "Oh, no. I've shot them away several seconds ago, so that they explode somewhere else, nowhere near me."

  "I hope. But do you realize just how busy a man you are going to be during those ten or twelve seconds?"

  "Fully." Cloud's face grew somber. "But I will be in full control. I won't be afraid of anything that can happen -anything. And," he went on, under his breath, "that's the hell of it."

  "QX," the Lensman admitted finally, "you can go. There are a lot of things you haven't mentioned, but you'll probably be able to work them out as you go along. I think I'll go out and work with the boys in the lookout station while you're doing your stuff. When are you figuring on starting?"

  "Now long will it take to get the flitter ready?"

  "A couple of days. Say we meet you there Saturday morning?"

  "Saturday, the tenth, at eight o'clock. I'll be there."

  And again Neal Cloud and Babe, the big blue ox, hit the road. And as he rolled, the physicist mulled over in his mind the assignment to which he had set himself.

  Like fire, only worse, intra-atomic energy was a good servant, but a terrible master. Man had liberated it before be could really control it. In fact, control was not yet, and perhaps never would be, perfect. Up to a certain size and activity, yes. They, the millions upon millions of self-limiting ones, were the servants. They could be handled, fenced in, controlled; indeed, if they were not kept under an exciting bombardment and very carefully fed, they would go out. But at long intervals, for some one of a dozen reasons-science knew so little, fundamentally, of the true inwardness of the intra-atomic reactions-one of these small, tame, self-limiting vortices flared, nova-like, into a large, wild, self-sustaining one. It ceased being a servant then, and became a master. Such flare-ups occurred, perhaps, only once or twice in a century on Earth; the trouble was that they were so utterly, damnably permanent. They never went out. And no data were ever secured for every living thing in the vicinity of a flare-up died; every instrument and every other solid thing within a radius of a hundred feet melted down into the reeking" boiling slag of its crater.

  Fortunately, the rate of growth was slow-as slow" almost, as it was persistent-otherwise Civilization would scarcely have had a planet left. And unless something could be done about loose vortices before too many years, the consequences would be really serious. That was why his laboratory had been established in the first place.

  Nothing much had been accomplished so far. The tractor beam that would take hold of them had never been designed. Nothing material was of any use, it melted. Pressors worked, after a fashion: it was by the use of these beams that they shoved the vortices around, off into the waste places-unless it proved cheaper to allow the places

  where they had come into being to remain waste places. A few, through sheer luck, had been blown into self-limiting bits by duodec. Duodec-aplylatomate, the most powerful" the most frightfully detonant explosive ever invented upon all the known planets of the First Galaxy. But duodec had taken an awful toll of life. Also, since it usually scattered a vortex instead of extinguishing it, duodec had actually caused far more damage than it had cured.

  No end of fantastic schemes had been proposed" of course; of varying degrees of fantasy. Some of them sounded almost practical. Some of them had been tried; some of them were still being tried. Some" such as the perennially-appearing one of building a huge hemispherical hull in the ground under and around the vortex, installing an inertialess drive, and shooting the whole neighborhood out into space, were perhaps feasible from an engineering standpoint. They were, however" potentially so capable of making things worse that they would not be tried save as last ditch measures. In short, the control of loose vortices was very much an unsolved problem.

  Number One vortex, the oldest and worst upon Tellus, had been pushed out into the Badlands; and there, at eight o'clock on the tenth" Cloud started to work upon it.

  The "lookout station," instead of being some such ramshackle structure as might have been deduced from the Lensman's casual terminology, was in fact a fully-equipped observatory. Its staff was not large-eight men worked in three staggered eight-hour shifts of two men each-but the instruments! To develop them had required hundreds of man-years of time and near miracles of research, not the least of the problems having been that of developing shielded conductors capable of carrying truly through fiveply screens of force the converted impulses of the very radiations against which those screens were most effective. For the observatory" and the long approach to it as well, had to be screened heavily; without such protection no life could exist there.

  This problem and many others had been solved, however" and there the instruments were. Every phase and factor of the vortex's existence and activity were measured and recorded continuously, throughout every minute of every day of every year. And all of these records were summed up"

  integrated, into the "Sigma" curve. This curve, while only an incredibly and senselessly tortuous line to the layman's eye, was a veritable mine of information to the initiate.

  Cloud glanced along the Sigma curve of the previous forty-eight hours and scowled, for one jagged peak, scarcely an hour old, actually punched through the top line of the chart.

  "Bad, huh, Frank?" he grunted.

  "Plenty bad, Storm, and getting worse," the observer assented. "I wouldn't wonder if Carlowitz were right, after all-if she ain't getting ready to blow her top I'm a Zabriskan fontema's maiden aunt."

  "No periodicity-no equation, of course." It was a statement, not a question. The Lensman ignored as completely as did the observer, if not as flippantly, the distinct possibility that at any moment the observatory and all that it contained might be resolved into their component atoms.

  "None whatever," came flatly from Cloud. He did not need to spend hours at a calculating machine; at one glance he knew, without knowing how he knew, that no equation could be made to fit even the weighted-average locus of that wildly-shifting Sigma curve. "But most of the cycles cut this ordinate here-seven fifty-one-so I'll take that for my value. That means nine point nine or six kilograms of duodec basic charge, with one five per cent over and one five per cent under that for alternates. Neocarballoy casting, fifty-three millimeters on the basic, others in proportion. On the wire?"

  "It went out as you said it," the observer reported. "They'll have 'em here in fifteen minutes."

  "QX-I'll get dressed, then."

  The Lensman and the observer helped him into his cumbersome, heavily-padded armor. They checked his instruments, making sure that the protective devices of the suit were functioning at full efficiency. Then all three went out to the flitter. A tiny speedster, really; a torpedo bearing the stubby wings and the ludicrous tail-surfaces, the multifarious driving-, braking-, side-, top-, and under-jets so characteristic of the tricky, cranky, but ultra-maneuverable breed. But this one had something that the ordinary speedster or flitter did not carry; spaced around the needle beak there yawned the open muzzles of a triplex bomb-thrower.

  More checking. The Lensman and the armored Cloud both knew that every one of the dozens of instruments upon the flitter's special board was right to the bair; nevertheless each one was compared with the master-instrument of the observatory.

  The bombs arrived and were loaded in; and Cloud, with a casually-waved salute, steppe
d into the tiny operating compartment. The massive door-hitters have no airlocks" as the whole midsection is scarcely bigger than an airlock would have to be-rammed shut upon its fiber gaskets" the heavy toggles drove home. A cushioned form closed in upon the pilot, leaving only his arms and lower legs free.

  Then, making sure that his two companions had ducked for cover, Cloud shot his hitter into the air and toward the seething inferno which was Loose Atomic Vortex Number One. For it was seething, no fooling; and it was an inferno. The crater was a ragged, jagged hole a full mile from lip to lip and perhaps a quarter of that in depth. It was not, however, a perfect cone, for the floor, being largely incandescently molten, was practically level except for a depression at the center, where the actual vortex lay. The walls of the pit were steeply, unstably irregular, varying in pitch and shape with the hardness and refractoriness of the strata composing them. Now a section would glare into an unbearably blinding white puffing away in sparkling vapor. Again, cooled by an in rushing blast of air, it would subside into an angry scarlet, its surface crawling in a sluggish flow of lava. Occasionally a part of the wall might even go black, into pock-marked scoriae or into brilliant planes of obsidian.

  For always, somewhere, there was an enormous volume of air pouring into that crater. It rushed in as ordinary air. It came out, however, in a ragingly-up rushing pillar, as -as something else. No one knew-or knows yet, for that matter-exactly what a loose vortex does to the molecules and atoms of air. In fact, due to the extreme variability already referred to, it probably does not do the same thing for more than an instant at a time.

  That there is little actual combustion is certain; that is" except for the forced combination of nitrogen, argon, xenon, and krypton with oxygen. There is, however, consumption: plenty of consumption. And what that incredibly intense bombardment impinges up is ... is altered. Profoundly and obscurely altered, so that the atmosphere emitted from the crater is quite definitely no longer air as we know it. It may be corrosive, it may be poisonous in one or another of a hundred fashions, it may be merely new and different; but it is no longer the air which we human beings are used to breathing. And it is this fact, rather than the destruction of the planet itself, which would end the possibility of life upon Earth's surface.

  It is difficult indeed to describe the appearance of a loose atomic vortex to those who have never seen one; and, fortunately, most people never have. And practically all of its frightful radiation lies in those octaves of the spectrum which are invisible to the human eye. Suffice it to say, then, that it had an average effective surface temperature of about fifteen thousand degrees absolute-two and one-half times as hot as the sun of Tellus-and that it was radiating every frequency possible to that incomprehensible temperature, and let it go at that.

  And Neal Cloud, scurrying in his flitter through that murky, radiation-riddled atmosphere, setting up equations from the readings of his various meters and gauges and solving those equations almost instantaneously in his mathematical-prodigy's mind, sat appalled. For the activity level was, and even in its lowest dips remained, far above the level he had selected. His skin began to prickle and burn. His eyes began to smart and to ache. He knew what those symptoms meant; even the flitter's powerful screens were not stopping all the radiation; even his suit-screens and his special goggles were not stopping what leaked through. But he wouldn't quit yet; the activity might-probably wouldtake a nose-dive any instant. If it did, he'd have to be ready. On the other hand, it might blow up at any instant, too.

  There were two schools of mathematical thought upon that point. One held that the vortex, without any essential change in its physical condition or nature, would keep on growing bigger. Indefinitely, until, uniting with the other vortices of the planet, it had converted the entire mass of the world into energy.

  The second school, of which the aforementioned Carlowitz was the loudest voice, taught that at a certain stage of development the internal energy of the vortex would become so great that generation-radiation equilibrium could not be maintained. This would, of course, result in an explosion; the nature and consequences of which this Carlowitz was wont to dwell upon in ghoulishly mathematical glee. Neither school, however, could prove its point-or, rather, each school proved its point, by means of unimpeachable mathematics-and each hated and derided the other, loudly and heatedly.

  And now Cloud, as he studied through his almost opaque defenses that indescribably ravening fireball, that esuriently rapacious monstrosity which might very well have come from the deepest pit of the hottest hell of mythology, felt strongly inclined to agree with Carlowitz. It didn't seem possible that anything could get any worse than that without exploding. And such an explosion, he felt sure, would certainly blow everything for miles around into the smitheriest kind of smithereens.

  The activity of the vortex stayed high" way too high. The tiny control room of the Hitter grew hotter and hotter. His skin burned and his eyes ached worse. He touched a communicator stud and spoke.

  "Phil? Better get me three more bombs. Like these" except up around... ."

  "I don't check you. If you do that, it's apt to drop to a minimum and stay there," the Lensman reminded him. "It's completely unpredictable, you know."

  "It may, at that ... so I'll have to forget the five per cent margin and hit on the nose or not at all. Order me up two more, then-one at half of what I've got here, the other double it"" and he reeled off the figures for the charge and the casing of the explosive. "You might break out a jar of burn-dressing, too. Some fairly hot stuff is leaking through."

  "We'll do that. Come down, fast!"

  Cloud landed. He stripped to the skin and the observer smeared his every square inch of epidermis with the thick" gooey stuff that was not only a highly efficient screen against radiation, but also a sovereign remedy for new radiation burns. He exchanged his goggles for a thicker, darker, heavier pair. The two bombs arrived and were substituted for two of the original load.

  "I thought of something while I was up there," Cloud informed the observers then. "Twenty kilograms of duodec is nobody's firecracker, but it may be the !east of what's going to go off. Have you got any idea of what's going to become of the energy inside that vortex when I blow it out?"

  "Can't say that I have." The Lensman frowned in thought. "No data."

  "Neither have I. But I'd say that you better go back to the new station-the one you were going to move to if it kept on getting worse."

  "But the instruments . . :' the Lensman was thinking" not of the instruments themselves, which were valueless in comparison with life, but of the records those instruments would make. Those records were priceless.

  "I'll have everything on the tapes in the flitter," Cloud reminded.

  "But suppose... ."

  "That the flitter stops one, too--or doesn't stop it, rather? In that case, your back station won't be there, either, so it won't make any difference." How mistaken Cloud was!

  "QX," the Chief decided. "We'll leave when you do just in case."

  Again in air, Cloud found that the activity, while still high, was not too high" but that it was fluctuating too rapidly. He could not get even five seconds of trustworthy prediction, to say nothing of ten. So he waited, as close as he dared remain to that horrible center of disintegration.

  The flitter hung poised in air, motionless, upon softly hissing under-jets. Cloud knew to a fraction his height above the ground. He knew to a fraction his distance from the vortex. He knew with equal certainty the density of the atmosphere and the exact velocity and direction of the wind. Hence, since he could also read closely enough the momentary variations in the cyclonic storms within the crater, he could compute very easily the course and velocity necessary to land the bomb in the exact center of the vortex at any given instant of time. The hard part the thing that no one had as yet succeeded in doing-was to predict, for a time far enough ahead to be of any use" a usably close approximation to the vortex's quantitative activity. For, as has been said, he had to o
ver-blast, rather than under-, if he could not hit it "on the nose:" to underblast would scatter it all over the state.

  Therefore Cloud concentrated upon the dials and gauges before him; concentrated with every fiber of his being and every cell of his brain.

  Suddenly, almost imperceptibly, the Sigma curve gave signs of flattening out. In that instant Cloud's mind pounced. Simultaneous equations: nine of them, involving nine unknowns. An integration in four dimensions. No matter-Cloud did not solve them laboriously, one factor at a time. Without knowing how he had arrived at it, he knew the answer; just as the Posenian or the Rigellian is able to perceive every separate component particle of an opaque, three-dimensional solid, but without being able to explain to anyone how his sense of perception works. It just is, that's all.

  Anyway, by virtue of whatever sense or ability it is which makes a mathematical prodigy what he is, Cloud knew that in exactly eight and three-tenth seconds from that observed instant the activity of the vortex would be slightly-but not too far-under the coefficient of his heaviest bomb. Another flick of his mental trigger and he knew the exact velocity he would require. His hand swept over the studs, his right foot tramped down, hard, upon the firing lever; and, even as the quivering flitter shot forward under eight Tellurian gravities of acceleration" he knew to the thousandth of a second how long he would have to hold that acceleration to attain that velocity. While not really long-in seconds-it was much too long for comfort. It took him much closer to the vortex than he wanted to be; in fact, it took him right out over the crater itself.

  But he stuck to the calculated course, and at the precisely correct instant he cut his drive and released his largest bomb. Then, so rapidly that it was one blur of speed, he again kicked on his eight G's of drive and started to whirl around as only a speedster or a flitter can whirl. Practically unconscious from the terrific resultant of the linear and angular accelerations, he ejected the two smaller bombs. He did not care particularly where they lit, just so they didn't light in the crater or near the observatory, and he had already made certain of that. Then" without waiting even to finish the whirl or to straighten her out in level flight, Cloud's still-flying hand darted toward the switch whose closing would energize the Bergenholm and make the flitter inertialess.
