A Deepness in the Sky (32 page)

The babies seemed to sense his distaste, and retreated shyly from sight. "

Never mind," said Sherkaner, in that oblivious way of his. "They'll come out and play once we're indoors."

Sherkaner led him inside, talking all the way about how much he had to show him, how good it was that Hrunkner was finally visiting. The years had changed Underhill, physically at least. Gone was the painful leanness; he had been through several molts. The fur on his back was deep and paternal, strange to see on anyone in this phase of the sun. The tremor in his head and forebody was a little worse than Unnerby remembered.

They walked through a foyer big enough for a hotel, and down a wide spiral of steps that looked out upon wing after wing of Sherkaner's "little hillhouse." There were plenty of other people here, servants perhaps, though they didn't wear the livery that the super-rich usually demanded. In fact, the place had the utilitarian feel of corporate or government property. Unnerby interrupted the other's nonstop chatter with, "This is all a front, isn't it, Underhill? The King never sold this hill at all, just transferred it." To the Intelligence Service.

"No, really. I do own the ground; I bought it myself. But, um, I do a lot of consulting, and Victory—I mean Accord Intelligence—decided that security was best served by setting up the labs right here. I have some things to show you."

"Yeah. Well, that's the point of my visit, Sherk. I don't think you're working on the right things. You've pushed the Crown into going all out for—I assume we can talk freely here?"

"Yes, yes, of course."

Ordinarily, Unnerby wouldn't have accepted such a casual assertion, but he was beginning to realize how thoroughly secure the building was. There was plenty of Sherkaner design, the logarithmic spiral of the main rooms for instance, but there was also Victory's touch, the—guards, he now realized—lurking everywhere, the crisply clean nature of the carpets and walls. This place was probably as safe as Unnerby's labs inside Lands Command. "Okay. You've pushed the Crown into going all out for atomic power. I'm managing more men and equipment than a billionaire, including several people almost as smart as you are." In fact, though Hrunkner Unnerby was still a sergeant, his job was about as far from that rank as one could get. His life these days was beyond his wildest contractor's dream.

"Good, good. Victory has a lot of faith in you, you know." He led his guest into a large and peculiar room. There were bookcases and a desk, all overflowing with reports, randomly piled books, and notepaper. But the bookcases were fastened to a cobblie jungle gym, and children's books were mixed with the arcana. His two babies hopped from his back and scuttled up the gym. Now they peered down upon them from the ceiling. Sherkaner pushed books and magazines off a lower perch and waved for Unnerby to seat himself. Thank God he didn't try to change the subject.

"Yeah, but you haven't seen my reports."

"Yes, I have. Victory sends them to me, though I haven't had time to read them."

"Well, maybe you should!"Deep Secret reports are sent to him and hedoesn't have time to read them—and he's the cobber who started it all. "Look, Sherkaner, I'm telling you it's not working out. In principle, atomic power can do everything we need. In practice—well, we've made some really deadly poisons. There are things like radium but a lot easier to produce in bulk. We've also got one isotope of uranium that's very hard to isolate, but I think if we do, we can make a hell of a bomb: we can give you the energy to keep a city warm through the Dark, but all in less than a second!"

"Excellent! That's a start."

"That excellent start may be as far as it gets. I've had three labs taken over by the bomb cobbers. Trouble is, this is peacetime; this technology is going to leak out, first to mining interests, then to foreign states. Can you imagine what will happen once the Kindred and the Old Tiefers and God knows who else starts making these things?"

That seemed to penetrate Underhill's durable armor of inattention. "...Yes, that will be very bad. I haven't read your reports, but Victory is up here often. Technology gives us wonders and terrible dangers. We can't have one without the other. But I'm convinced we won't survive unless we play with these things. You're seeing just one part of it all. Look, I know Victory can get you more money. Accord Intelligence has a good credit rating. They can go beyond the tithe for a decade without having to show a profit. We'll get you more labs, whatever you want—"

"Sherkaner, have you heard of ‘forcing the learning curve'?"

"Well, uh—" Clearly he had.

"Right now, if I had all the wealth in the world, I could give you a city heating unit, maybe. It would suffer catastrophic failure every few years, and even when it was working ‘properly,' its transfer fluid—superheated steam, say—would be so radioactive that your city's residents would all be dead before the Dark was even ten years old. Beyond a certain point, throwing more money and technicians at a problem just doesn't help."

Sherkaner didn't answer immediately. Unnerby had the feeling that his attention was roaming around the top of the jungle gym, watching his two babies. This room was a truly bizarre combination of wealth, the old Underhill intellectual chaos, and the new Underhill paternity. Where the floor wasn't piled with books and knickknacks, he could see plush carpet. The wall covering was one of those superexpensive delusional patterns. The windows were quartz-paned, extending all the way to the high ceiling. They were cranked open now. The smell of ferns in the cool morning floated in past wrought-iron trellises. There were electric lamps by Underhill's desks and by the legholds of the bookcases, but they were all turned off now.

The only light was the green and near-red that filtered through the ferns. That was more than enough to read the titles on the nearest books. There were psychology, math, electronics, an occasional astronomy text—and lots of children's storybooks. The books were stacked in low piles, filling most of the space between toys and equipment. And it wasn't always clear which were Underhill's toys and which were the children's. Some of the stuff looked like travel souvenirs, perhaps from Victory's military postings: a Tiefer leg polisher, dried flowers that might have been an Islander garland. And over in the corner...it looked like a Mark 7 artillery rocket, for God's sake. The warhead hatch had been removed, and there was a dollhouse installed in place of the customary high explosives.

Finally Underhill said, "You're right, money alone won't make progress. It takes time to make the machines that make the machines, and so on. But we still have another twenty-five years or so, and the General tells me you are a genius at managing something this large."

Hrunkner felt an old pride in hearing that, more pride than for all the medals he had collected in the Great War; but if it hadn't been for Smith and Underhill, he never would have discovered he had such talents. He replied grumpily, careful not to give away how much such praise meant to him: "Thank you so much. But what I'm telling you is that none of that is enough. If you want this done in less than twenty years, I need something more."

"Yes, what?"

"You, damn it! Your insight! Since the first year of the project, you've been hidden away up here in Princeton, doing God knows what."

"Oh....Look Hrunkner, I'm sorry. The atomic power stuff just isn't very interesting to me anymore."

Knowing Underhill for all these years, Unnerby should not have been surprised by the comment. Nevertheless, it made him want to chew on his hands. Here was a fellow who abandoned fields of endeavor before others even knew they existed. If he were simply a crank, there'd be no problem. As it was, sometimes Unnerby would have cheerfully killed the cobber.

"Yes," continued Underhill, "you need more bright people. I'm working on that, you know; I have some things I want to show you. But even so," he said, obliviously pouring fuel on the fire, "my intuition is that atomic power will turn out to be relatively easy, compared to the other challenges."

"Such. As. What?"

Sherkaner laughed. "Such as raising children, for example." He pointed at the antique pendulum clock on the side wall. "I thought the other cobblies would be here by now; maybe I should show you the institute first." He got off his perch, began waving in that silly way parents do to small children. "Come down, come down. Rhapsa, stay off the clock!" Too late: the baby had scuttled off the gym, made a flying leap onto the pendulum, and slid all the way to the floor. "I've got so much junk here, I'm afraid something will fall on the babies and squash them." The two ran across the floor, hopped into their appointed places in their father's fur. They were scarcely bigger than woodsfairies.

Underhill had gotten his institute declared a division of Kingschool. The hillhouse contained a number of classrooms, each occupying an arc of the outside perimeter. And it wasn't Crown funds that paid for most of it, at least according to Underhill. Much of the research was simply proprietary, paid for by companies that had been very impressed by Underhill. "I could have hired away some of Kingschool's best, but we made a deal. Their people continue to teach and do research downtown, but they get time up here, with a percentage of our overhead getting fed back to Kingschool. And up here, what counts is results."

"No classes?"

When Sherkaner shrugged, the two little ones bobbed up and down on his back and made excited littlemeeping, sounds that probably meant, "Do it again, Daddy!"

"Yes, we have classes...sort of. The main thing is, people get to talk to other people, across many specialties. Students take a risk because things are so unstructured. I've got a few who are having a good time, but who aren't bright enough for this to work for them."

Most of the classrooms had two or three persons at the blackboards, and a crowd watching from low perches. It was hard to tell who was the prof and who the student. In some cases, Hrunkner couldn't even guess the field being discussed. They stopped for a moment by one door. A current-generation cobblie was lecturing a bunch of old cobbers. The blackboard scratching looked like a combination of celestial mechanics and electromagnetics. Sherkaner stopped, waved a smile at the people in the room. "You remember the aurora we saw in Dark? I have a fellow here who thinks that maybe it was caused by objects in space, things that are exceptionally dark."

"They weren't dark when we saw them."

"Yes! Maybe they actually have something to do with the start of the New Sun. I have my doubts. Jaybert doesn't know much celestial mechanics yet. Hedoes know E&M. He's working on a wireless device that can radiate at wavelengths of just a few inches."

"Huh? That sounds more like super far-red than radio."

"It's not something we could ever see, but it's going to be neat. He wants to use it as an echo finder for his space rocks."

They walked farther down the hall. He noticed that Underhill was suddenly silent, no doubt to give him time to think on the idea. Hrunkner Unnerby was a very practical fellow; he suspected that was the reason he was essential to some of General Smith's wilder projects. But even he could be brought up short by an idea that was spectacular enough. He had only the vaguest notion how such short wavelengths would behave, though they should be highly directional. The power needed for echo detection would vary as the inverse fourth power of the range—they'd have effective ground uses for it before they ever had enough juice to go looking for rocks in outer space. Hmm. The military angle could be more important than anything this Jaybert was planning...."Has anyonebuilt this high-frequency transmitter?"

His interest must have shown; Underhill was smiling more and more. "Yes, and that's Jaybert's real work of genius, something he calls a cavity oscillator. I've got a little antenna on the roof; it looks more like a telescope mirror than a radio mast. Victory installed a row of relays down the Westermost Range to Lands Command. I can talk to her as reliably as over the telephone cable. I'm using it as a test bed for one class's crypto schemes. We'll end up with the most secure, high-volume wireless you can imagine."

Even if Jaybert's stargazing never works out.Sherkaner Underhill was as crazy as ever, and Unnerby was beginning to see what he was getting at, why he refused to drop everything and work on atomic power. "You really think this school is going to produce the geniuses we need at Lands Command?"

"It's going to find them, anyway—and I think we're bringing out the best in what we find. I've never had more fun in my life. But you have to be flexible, Hrunk. The essence of real creativity is a certain playfulness, a flitting from idea to idea without getting bogged down by fixated demands. Of course, you don't always get what you thought you were asking for. From this era on, I think invention will be the parent of necessity—and not the other way around."

That was easy for Sherkaner Underhill to say. He didn't have to engineer the science into reality.

Underhill had stopped at an empty classroom; he peeked in at the blackboards. More gobbledegook. "You remember the cam-and-gear devices that Lands Command used in the War, to figure ballistic tables? We're making things like that with vacuum tubes and magnet cores. They're a million times faster than the cam gadgets, and we can input the numbers as symbol strings instead of vernier settings. Your physicists will love it." He chuckled. "You'll see, Hrunk. Except for the fact that the inventions are first-patented by our sponsors, you and Victory will have more than enough to keep you happy... ."

They continued up the long spiral stair. It opened finally onto an atrium near the top of the hill. There were higher hills around Princeton, but the view from here was spectacular enough, even in a cool drizzle. Unnerby could see a trimotor coming in at the airport. Tracts of late-phase development on the other side of the valley were the colors of wet granite and just-laid asphalt. Unnerby knew the company on that job. They had faith in the rumors that there would be power available to live long into the next Dark. What would Princeton be like if that were so? A city under the stars and hard vacuum, yet not asleep, and its deepnesses empty. The biggest risks would be late in the Waning Years, when people must decide whether to stock up for a conventional Dark, or gamble on what Hrunkner Unnerby's engineers thought they could do. His nightmares were not of failure, but of partial success.
