Peter Lamont had been two years old when Hallam had picked up his altered tungsten for the first time. When he was twenty-five, he joined Pump Station One with the print on his own doctoral dissertation still fresh and accepted a simultaneous appointment on the Physics faculty of the university.
It was a remarkably satisfactory achievement for the young man. Pump Station One was lacking in the glisten of the later stations but it was the granddaddy of them all, of the entire chain that girdled the planet now even though the entire technology was only a couple of decades old. No major technological advance had ever caught hold so rapidly and so entirely and why not? It meant free energy without limit and without problems. It was the Santa Claus and the Aladdin's lamp of the whole world.
Lamont had taken the job in order to deal with problems of the highest theoretical abstraction and yet he found himself interested in the amazing story of the development of the Electron Pump. It had never been written up in its entirety by someone who truly understood the theoretical principles (in so far as they could be understood) and who had some ability in translating the complexities for the general public. To be sure, Hallam himself had written a number of articles for the popular media, but these did not represent a connected, reasoned history - something Lamont yearned to supply.
He used Hallam's articles to begin with, other reminiscences in published form - the official documents so to speak - carrying them through to Hallam's world-shaking remark, the Great Insight, as it was often called (invariably with capital letters).
Afterward, of course, when Lamont had experienced his disillusionment, he began digging deeper, and the question arose in his mind as to whether Hallam's great remark had really been Hallam's. It had been advanced at the seminar which marked the true beginning of the Electron Pump and yet, as it turned out, it was extraordinarily difficult to get the details of that seminar and quite impossible to get the voice recordings.
Eventually, Lamont began to suspect that the dimness of the footprints left on the sands of time by that seminar was not entirely accidental. Putting several items ingeniously together, it began to seem that there was a reasonable chance that John F.X. McFarland had said something very nearly like the crucial statement Hallam had made - and had done so before Hallam.
He went to see McFarland, who was featured not at all in the official accounts, and who was now doing upper-atmosphere research, with particular reference to the Solar wind. It was not a top-echelon job, but it had its perquisites, and it had more than a little to do with Pump effects. McFarland had clearly avoided suffering the fate of oblivion that had overtaken Denison.
He was polite enough to Lamont and willing to talk on any subject except the events of that seminar. That he simply didn't remember.
Lamont insisted, quoted the evidence he had gathered.
McFarland took out a pipe, filled it, inspected its contents thoroughly, and said, with a queer intentness. "I don't choose to remember, because it doesn't matter; it really doesn't. Suppose I laid claim to having said something. No one would believe it. I would look like an idiot and a megalomaniac one."
"And Hallam would see to it that you were retired?"
"I'm not saying that, but I don't see that it would do me any good. What's the difference, anyway?"
"A matter of historical truth!" said Lamont
"Oh, bull. The historical truth is that Hallam never let go. He drove everyone into investigating, whether they wanted to or not. Without him, that tungsten would eventually have exploded with I don't know how many casualties. There might never have been another sample, and we might never have had the Pump. Hallam deserves the credit for it, even if he doesn't deserve the credit, and if that doesn't make sense, I can't help it, because history doesn't make sense."
Lamont wasn't satisfied with that, but he had to make it do, for McFarland would simply say no more.
Historical truth!
One piece of historical truth that seemed beyond question was that it was the radioactivity that pulled "Hallam's tungsten" (this is what it was called as a matter of historical custom) into the big time. It didn't matter whether it was or was not tungsten; whether it had or had not been tampered with; even whether it was or was not an impossible isotope. Everything was swallowed up in the amazement of something, anything, which showed a constantly increasing intensity of radioactivity under circumstances that ruled out the existence of any type of radioactive breakdown, in any number of steps, then known.
After a while, Kantrowitsch muttered, "We'd better spread it out. If we keep it in sizable lumps it will vaporize or explode or both and contaminate half the city."
So it was powdered and scattered, and mixed with ordinary tungsten at first and then, when the tungsten grew radioactive in its turn, it was mixed with graphite, which had a lower cross-section to the radiation.
Less than two months after Hallam had noticed the change in the bottle's contents, Kantrowitsch, in a communication to the editor of Nuclear Reviews, with Hallam's name appended as co-author, announced the existence of plutonium-186. Tracy's original determination was thus vindicated but his name was not mentioned, either then or later. With that Hallam's tungsten began to take on an epic scale and Denison began to note the changes that ended by making him a non-person.
The existence of plutonium-186 was bad enough. To have been stable at the start and to display a curiously increasing radioactivity was much worse.
A seminar to handle the problem was organized. Kantrowitsch was in the chair, which was an interesting historical note, for it was the last time in the history of the Electron Pump that a major meeting was held in connection with it that was chaired by anyone but Hallam. As a matter of fact, Kantrowitsch died five months later and the only personality with sufficient prestige to keep Hallam in the shade was removed.
The meeting was extraordinarily fruitless until Hallam announced his Great Insight, but in the version as reconstructed by Lamont, the real turning point came during the luncheon break. At that time, McFarland, who is not credited with any remarks in the official records, although he was listed as an attendee, said "You know, what we need is a little bit of fantasy here. Suppose - "
He was speaking to Diderick van Klemens, and Van Klemens reported it sketchily in a kind of personal shorthand in his own notes. Long before Lamont had succeeded in tracking that down, Van Klemens was dead, and though his notes convinced Lamont himself, he had to admit they would not make a convincing story without further corroboration. What's more, there was no way of proving that Hallam had overheard the remark. Lamont would have been willing to bet a fortune that Hallam was within earshot, but that willingness was not satisfactory proof either.
And then, suppose Lamont could prove it. It might hurt Hallam's egregious pride, but it couldn't really shake his position. It would be argued that to McFarland, the remark was only fantasy. It was Hallam who accepted it as something more. It was Hallam who was willing to stand up in front of the group and say it officially and risk the derision that might be his. McFarland would surely never have dreamed of placing himself on official record with his "little bit of fantasy."
Lamont might have counter-argued that McFarland was a well-known nuclear physicist with a reputation to lose, while Hallam was a young radiochemist who could say anything he pleased in nuclear physics and, as an outsider, get away with it.
In any case, this is what Hallam said, according to the official transcript:
"Gentlemen, we are getting nowhere. I am therefore going to make a suggestion, not because it necessarily makes sense, but because it represents less nonsense than anything else I've heard . . . We are faced with a substance, plutonium-186, that cannot exist at all, let alone as an even momentarily stable substance, if the natural laws of the Universe have any validity at all. It follows, then, that since it does indubitably exist and did exist as a stable substance to begin with, it must have existed, at least to begin with, in a place or at a time or under circumstances where the natural laws of the Universe were other than they are. To put it bluntly, the substance we are studying did not originate in our Universe at all, but in another - an alternate Universe - a parallel Universe. Call it what you want.
"Once here - and I don't pretend to know how it got across - it was stable still and I suggest that this was because it carried the laws of its own Universe with it. The fact that it slowly became radioactive and then ever more radioactive may mean that the laws of our own Universe slowly soaked into its substance, if you know what I mean.
"I point out that at the same time that the plutonium-186 appeared, a sample of tungsten, made up of several stable isotopes, including tungsten-186, disappeared. It may have slipped over into the parallel Universe. After all, it is logical to suppose that it is simpler for an exchange of mass to take place than for a one-way transfer to do so. In the parallel Universe, tungsten-186 may be as anomalous as plutonium-186 is here. It may begin as a stable substance and slowly become increasingly radioactive. It may serve as an energy source there just as plutonium-186 would here."
The audience must have been listening with considerable astonishment for there is no record of interruption, at least until the sentence last recorded above, at which time Hallam seemed to have paused to catch his breath and perhaps to wonder at his own temerity.
Someone from the audience (presumably Antoine-Jerome Lapin, though the record is not clear) asked if Professor Hallam were suggesting that an intelligent agent in the para-Universe had deliberately made the exchange in order to obtain an energy source. The expression "para-Universe," inspired apparently as an abbreviation of "parallel-Universe," thus entered the language. This question contained the first recorded use of the expression.
There was a pause and then Hallam, more daring than ever, said - and this was the nub of the Great Insight - "Yes, I think so, and I think that the energy source cannot be made practical unless Universe and para-Universe work together, each at one half of a pump, pushing energy from them to us and from us to them, taking advantage of the difference in the natural laws of the two Universes."
Hallam had adopted the word "para-Universe" and made it his own at this point. Furthermore, he became the first to use the word "pump" (since invariably capitalized) in connection with the matter.
There is a tendency in the official account to give the impression that Hallam's suggestion caught fire at once, but it did not. Those who were willing to discuss it at all would commit themselves no farther than to say it was an amusing speculation. Kantrowitsch, in particular, did not say a word. This was crucial to Hallam's career.
Hallam could scarcely carry through the theoretical and practical implications of his own suggestion all by himself. A team was required and it was built up. But none of the team, until it was too late, would associate himself openly with the suggestion. By the time success was unmistakable, the public had grown to think of it as Hallam's and Hallam's alone. It was Hallam, to all the world, and Hallam alone, who had first discovered the substance, who had conceived and transmitted the Great Insight; and it was therefore Hallam who was the Father of the Electron Pump.
Thus, in various laboratories, pellets of tungsten metal were laid out temptingly. In one out of ten the transfer was made and new supplies of plutonium-186 were produced. Other elements were offered as bait and refused . . . But wherever the plutonium-186 appeared and whoever it was that brought the supply to the central research organization working on the problem, to the public it was an additional quantity of "Hallam's-tungsten."
It was Hallam again who presented some aspects of the theory to the public most successfully. To his own surprise (as he later said) he found himself to be a facile writer, and he enjoyed popularizing. Besides success has its own inertia, and the public would accept information on the project from no one but Hallam.
In a since famous article in the North American Sunday Tele-Times Weekly, he wrote, "We cannot say in how many different ways the laws of the para-Universe differ from our own, but we can guess with some assurance that the strong nuclear interaction, which is the strongest known force in our Universe, is even stronger in the para-Universe; perhaps a hundred times stronger. This means that protons are more easily held together against their own electrostatic attraction and that a nucleus requires fewer neutrons to produce stability.
"Plutonium-186, stable in their Universe, contains far too many protons, or too few neutrons, to be stable in ours with its less effective nuclear interaction. The plutonium-186, once in our Universe, begins to radiate positrons, releasing energy as it does so, and with each positron emitted, a proton within a nucleus is converted to a neutron. Eventually, twenty protons per nucleus have been converted to neutrons and plutonium-186 has become tungsten-186, which is stable by the laws of our own Universe. In the process, twenty positrons per nucleus have been eliminated. These meet, combine with, and annihilate twenty electrons, releasing further energy, so that for every plutonium-186 nucleus sent to us, our Universe ends up with twenty fewer electrons.
"Meanwhile, the tungsten-186 that enters the para-Universe is unstable there for the opposite reason. By the laws of the para-Universe it has too many neutrons, or too few protons. The tungsten-186 nuclei begin to emit electrons, releasing energy steadily while doing so, and with each emitted electron a neutron changes to a proton until, in the end, it is plutonium-186 again. With each tungsten-186 nucleus sent into the para-Universe, twenty more electrons are added to it.
"The plutonium/tungsten can make its cycle endlessly back and forth between Universe and para-Universe, yielding energy first in one and then in another, with the net effect being a transfer of twenty electrons from our Universe to their per each nucleus cycled. Both sides can gain energy from what is, in effect, an Inter-Universe Electron Pump."
The conversion of this notion into reality and the actual establishment of the Electron Pump as an effective energy source proceeded with amazing speed, and every stage of its success enhanced Hallam's prestige.
