Learning the World

A Scientific Romance

A Note on Translation

For convenience, some numbers used by characters who count in an octal system

have occasionally been rendered in decimal. Terms derived from a dead schol-arly

language are rendered as if from Latin. There is an explanation for this.

Population will mightily increase, and the earth will be a garden. Governments

will be conducted with the qui-etude and regularity of club committees. The

interest which is now felt in politics will be transferred to sci-ence; the latest news

from the laboratory of the chemist, or the observatory of the astronomer, or the

experimenting room of the biologist will be eagerly discussed. [...] Disease will be

extirpated; the causes of decay will be removed; immortality will be in-vented. And

then, the earth being small, mankind will migrate into space, and will cross the

airless Saharas which separate planet from planet, and sun from sun. The earth

will become a Holy Land which will be vis-ited by pilgrims from all the quarters of

the universe. Finally, men will master the forces of Nature; they will become

themselves architects of systems, manufactur-ers of worlds.—Winwood Reade, The

Martyrdom of Man, 1872

1—The Ship Generation

Learning the World

14364:05:1217:24 The world is four thousand years old. I was eight years old when I

found that out for myself. My name is Atomic Discourse Gale and this is the first

time I have written something that anyone in the world can read. It is strange and

makes me feel a little self-conscious, but I reassure myself that not many people will

read it anyway.

14364:05:1318:30

That was a joke. I see I have a few readers. J—— wants to know how I found out

the age of the world. It was six years ago now but I remember it quite well. I was

very young then and didn't understand everything that happened, but looking back I

can see that it was a significant event in my life. That is why I mentioned it. So this is

what happened.

"How old is the world?"

I asked my caremother. "I don't know," she said. "Why don't you look it up?"

"I've looked it up," I said. "I don't believe it."

"Why not?"

"Seventeen billion years?" I said. "That's impossible."

"Ah," she said. "That's the universe. Well ... every-thing we can see. The stars and

galaxies."

I went off and formed a more careful query. Nothing came back. I returned to my

caremother. "This world," I said. "I can't find anything about that."

"All right," she said. She pointed up to the sky. "See up there ... where the sunline

enters the wall? Inside there, in the forward cone, you'll find what is called the keel."

"Like the bottom of a boat?"

"In a way, yes. It's really the base of the engine, and it's the first part of the ship to

be put in place. You will find the date of the final assembly there. And from that you

can work out the age of the world."

"You don't know what it is?"

"No," she said. She frowned, in the way adults have when they're searching. "It isn't

in memory."

"All right," I said. "I'll go and have a look."

"Good for you," she said. "I'll help you pack." So thirty minutes later I hitched my

little rucksack, heavy with a litre of water and a kilo of sandwiches, onto my

shoulders and set off to climb into the sky. I walked out of the estate and after a

while I found a lad-der at the edge of a dense and ancient clump of trees. The ladder

had been familiar to me since I was much smaller, but none of us had ever climbed

more than a few score steps on it. It soared into the sky like a kite string, the kinks of

its zigzag flights smoothing into a pale line and then disappearing. You couldn't

easily fall off it—it had close-spaced rings around it, and every thirty metres or so

there was a small platform and another flight. The first day I climbed a kilometre,

found a big platform, ate my sandwiches and drank my water, and pissed in a far

corner like an untrained kit-ten. I sat and watched the shadowline creep across the

land towards me. It reached me in what seemed a final rush, and the sunline turned

black. The land below was dim and beautiful in the farlight from the other side of the

world, and within minutes lights pricked on all across that shaded scene. After a

while I curled up and went to sleep. When I woke the sunline was bright again. It

seemed as far away as ever, and the ground a long way below. I was just thinking of

setting off back down when a crow landed on the platform, carrying a package.

"Breakfast," said the bird. "And dinner. Your ma says hi."

"Tell her thank you," I said.

"Will do," said the crow, and flew off. Crows don't have much conversation. I

unwrapped the package and found, to my great delight, hot coffee and hot

berry-bread for breakfast, and a fresh bottle of water and an-other pack of

sandwiches for later. As I ate my breakfast I let my clothes clean me. Normally I

would have washed. The clothes did a reasonable job but made my skin feel crawly

and tickly. After I had eaten I chewed a tooth-cleaner and gazed around. The estate

looked tiny, and I could see a whole sweep of other es-tates and towns, lakes and

hills and plains, along and around. I was almost level with the tops of the slag heaps

piled against the forward wall. Between me and the sunline a few clouds drifted: far

away, I could see rain falling from one, onto a town. It was strange to see rain from

the outside, as a distinct thing rather than a condition. More interesting was to see

aircraft flying high above me, and a few below, taking off or landing. I faced

resolutely upward, and continued my climb.

Of course I did not climb all the way. I was a tough and determined person, but it

would have taken a month even if the ladder had extended all the way there, which it

did not. What happened, about halfway through my second day, was that a small

aircraft landed on a large platform a few hundred metres above me, and when I

reached it, a man stood waiting for me. He even reached over and took my hand and

hauled me up the last few steps, which I thought was unneces-sary, but I made no

objection. He then backed away and we looked at each other for a few seconds. He

was wearing a loose black suit, and his skin was not a lot lighter. His features might

have been carved out of mahogany, with deep lines scored in it around the eyes and

mouth. "My name is Constantine the Oldest Man," he said. The name meant nothing

to me but seemed suitable.

"Mine is Atomic Discourse Gale," I said, sitting down on the platform.

"I know," he said. "Your caremother asked me to meet you." He jerked his head

back, indicating the aeroplane. "I can take you to the keel, if you like."

I had been determined to reach the keel myself; but I saw the man and the aircraft as

part of my adven-ture, and therefore within my resolution rather than as a weakening

or dilution of it. Besides, I now had a much better idea of how long it would take to

climb all the way.

"All right," I said. "Thank you."

He stepped over and peered into my eyes. I noticed a tiny shake of his head, as if

something that might have been in my eyes wasn't there (a nictitating mem-brane, I

now realise). He led me over to the aircraft, motioned me to sit in the front and lower

seat, showed me how to strap up, and passed me a set of wrap-arounds, transparent

and tinted. I slipped them on. He climbed in behind me and started the engine. The

pro-peller was behind us both, the wing above. After the engine had built up some

power the little machine shook and quivered, then shot to the edge of the plat-form

and dropped off. I may have squealed. It dipped, then soared. My stomach felt

tugged about. Wind rushed past my face. The collar of my jacket crept up over the

top and sides of my head, and stiffened. I hadn't known it had that capability.

We flew in an irregular spiral, perhaps to avoid stair-ladders and other obstacles

invisible to me, but always up. I looked down, at the ground. I could see houses and

vehicles, but not people. Other small aircraft buzzed about the sky, at what seemed

frighteningly short clearances. The air felt thinner as we climbed. As we levelled out I

could feel the sunline hot on my shoulders, bright out of the corners of my eyes.

Ahead loomed the forward wall. Featureless from the dis-tances at which I had

always seen it, it now looked complex, with gigantic pipes snaking across it and

great clusters of machinery clamped to it. Wheels turned and pistons and elevators

moved up and down. Rectangular black slots became visible, here and there on the

surface, and we flew towards one. As naively as I'd thought I could climb to the

sunline, I'd imagined we would fly to it, but we flew into the slot—it was two

hundred metres wide by at least thirty high—and landed. Other small aircraft were

parked in the artificial cavern. It was in fact a hangar. Constantine helped me out of

the seat. My memory may be playing tricks, but I fancy I felt slightly lighter.

"I thought we were going to fly all the way," I said, trying not to sound querulous.

"The air doesn't go all the way to the sunline," Constantine told me. "So we will take

the lift."

I followed him across the broad floor to an incon-spicuous door. Behind it was an

empty lift, big enough to hold about a dozen people. Its walls were transpar-ent,

giving a view of a dark chasm within which gigan-tic shapes moved vertically,

illuminated by occasional random lights. The doors hissed shut and the lift began to

ascend. So rapid was its acceleration that my knees buckled. Constantine grasped

my shoulder.

"Steady," he said. "It doesn't get worse than carry-ing someone piggyback."

Vaguely affronted, I straightened up and stared out. Looking down made me dizzy,

so I looked up. The space in which we moved was in fact quite shallow in relation to

its size. We were headed for a bright spot above, which I knew to be some

manifestation of the sunline. The lift decelerated far more gradually and gently than it

had accelerated. As it did so, I found that I was becoming lighter. An experimental

downward thrust of the toes sent me a metre into the air. I yelled out, startled and

delighted, as I fell back.

Constantine laughed. "Hold the bar," he said.

The lift halted, as if hesitating, then shot upward again. We passed through a hatch

or hole. For a mo-ment I was pressed against the wall of the lift; then I found myself

weightless. Constantine glided over my head, twisting and somersaulting at the same

time. I let go of the bar, flailing. The sensation of falling was for a moment terrifying.

My stomach heaved, then settled.

"It's all right," he said. "We're in the forward cone now." The teeth of his smile were

a vivid white. He caught my elbow and swung me onto his back. I gripped fistfuls of

fabric at his shoulders and clung. He grinned sideways at me and kicked off. The

door of the lift hissed open. My eardrums clicked. We skimmed above the floor of a

long tube. Shafts of light stabbed down from small holes or windows above us; my

eyes adjusted quickly to the dimness, not darker, in truth, than indoor lighting. About

three metres high by two wide, the tube ran straight into the distance as far as I could

see. Within it, as we moved along, I noticed many other corridors branching off.

Constantine's foot flicked at a wall and we hurtled into one of these side corridors.

There was a smell of earth and ozone, of plant and animal and machine. Rapidly and

bewilderingly, we passed through a succession of corridors and chambers, within

which I glimpsed machinery and in-struments, gardens hanging in midair, glowing

lights and optical cables, and many people flying or floating or scuttling like

monkeys along tubes or flimsy lad-ders. And what strange people they were, long of

limb and lithe of muscle and wild of hair. Naked as the day they were born, lots of

them; or looking similar, but in bright-coloured skintight suits; others crusted with

stiff sculptured garments, like the camouflage of a leaf insect, or swathed in silky

balloon sleeves and pants. Their indifference to orientation was for me disorient-ing;

looking at their antics I felt a resurgence of unease in my belly.

I closed my eyes, and when I opened them again we had reached our destination.

We floated near the floor of the biggest enclosed space I'd ever been in, apart from

the world itself. The floor was smooth, and ex-tended far ahead of us, and curved

up on either hand like a smaller version of the curve of the world. Up and down had

in a manner been restored. The thing that I craned my neck to look at, from my

vantage on Constantine's back, was unmistakably up. Above us it vanished into

shadows, ahead it stretched and tapered into distance. A thousand or more metres

long, hun-dreds of metres high, it was complex, flanged, fluted and voluted, yet

seemed cast from a single block of metal, ancient and pitted as an iron asteroid.

There was one piece of metal, however, that shone bright and dis-tinct from the rest:

a metre-long rectangle of burnished brass, on which some writing was engraved. We

hung in the still, rust-scented air not an arm's length from it. The inscription was as

follows:

Sunliner But the Sky, My Lady! The Sky!

Forged this day 6 February 10 358 AG.

Constantine reached around and disengaged me from his back. We drifted for a few

minutes, hand in hand.

"I never knew the world had a name," I said.

"I named it," said Constantine.

"Why did you call it that?" I asked.

He swung me and caught my other hand, like a dancer, and once again gazed into

my face as if look-ing for something.

"You'll know one day," he said.

I know now.

Horrocks Mathematical blinked away the girl's biolog. It seemed that like all of the

ship generation she was maturing on schedule. He himself had gone through

adolescence, five or six years ago now, without any such epiphany. The

Mathematical were tenth-generation crew and Horrocks had never had to suffer a

grounded upbringing. Although born in the ship he did not con-sider himself or his

cohort part of the ship generation. They were among the youngest members of the

crew, that was all. Through the foliage of the air-tree and the skin of the bubble in

which he floated he could see the land twenty-five kilometres below—its parks and

copses, rivers and lakes, estates and towns an ideal of savannah and suburbia that

was said to be a hard-wired part of the human evolutionary heritage, though only

manifested among flatfooters. As a free-flyer, Horrocks felt that his was a more

evolved biophilia.

The air-tree, growing from a hydroponic tank, its branches grafted to form an open

wickerwork sphere, was about fifty metres in diameter and five years older than he

was. Horrocks pushed through the lianas that crisscrossed its interior and thrust

himself out into the greater confinement of the bubble. He had work to do. The

bubble was one of scores strung on a circular ca-ble around the sunline like beads

on a bangle. The ca-ble contra-rotated the ground, putting the bubbles in an

approximation of free fall. Only the slight intermittent backward tug of the small jets

that countered the effect of the ship's deceleration broke the spell, but that was all

they broke.

On the other side of the bubble, making a rocky counterpart to the air-tree, hung a

tethered lump of as-teroid clinker about a hundred metres across. A thrust of his feet

took Horrocks towards it. As he drifted he tugged on his cuffs. The fabric slid over

his hands and fingers, to form tough gloves by the time he impacted the rock's side.

He worked his way over and around the rock, checking each of the scores of

machines he'd spent the past few days bolting to its surface. They jut-ted out a metre

or so; their display and control panels—some of them simple touch screens, others

elaborate but rugged arrangements of knobs, push buttons, and dials, and a few

remote brain interfaces—were already filmed or crusted with dust. All in order,

however. The tenebrific shade had passed over him many times, and half the

morning had passed, before he was satisfied with that.

Ready for the kids to play with. Horrocks tweaked a final bolt and took a deep

breath. He pulled his collar up over his head and down over his face until it sealed

under his chin, and launched himself towards the bub-ble's airlock. The scooter on

the other side of it took him, on a spiralling trajectory that would have dizzied and

sickened a flatfooter, around and along the sunline to the airlock of the forward wall.

Once inside, he pulled his hood off his face, gasped a couple of times, and relaxed

into his own world, the world of the for-ward cone.

Immediately the corner of his eye filled with mes-sages. It was not that they were

unavailable outside, but that they were easier to ignore. He blinked through them

rapidly, discarding most as routine. One from his friend Awlin Halegap, a speculator,

urged him to check one of the latest observations of the new system into which the

ship was decelerating.

Horrocks smiled—Awlin's speculations were often indeed speculative, and had

already cost Horrocks and other acquaintances almost as much credit as they had

profited them in the last couple of years—but tuned in to the list anyway. Most of

the observations were of the first tranche of asteroids detected, and of the moons of

the ringed gas giant and the waterworld that were the most prominent bodies in the

system, and a few of the planets. The one Awlin had tagged was of the least

immediately usable of the planets: the habitable-zone terrestrial. When he expanded

the data he could see nothing of note; its amount and resolution, from a distance of

several light-hours, were sparse. He made contact with Awlin.

"What's the big deal?" Horrocks asked.

"Lightning spikes," replied Awlin.

"Thank you," said Horrocks. He concentrated on the section of the data on the

relevant portion of the electromagnetic spectrum. There it was: a recurring surge of

activity that suggested an agitated atmosphere, in which a great deal of interesting

stuff was going on. Research claims on the planet were sure to become a lucrative

proposition. So Awlin thought, at any rate.

Horrocks considered it for a moment, then patched to his broker and unloaded a

hundred in waterworld phytochemicals for a thousand in terrestrials: blue-sky

investments. As he worked his way through the capil-laries of corridor to the main

hollows he checked their progress by the minute. Their rating barely twitched. He

sent a copy of the flat wavy line to Awlin, with a querying tic.

"See?" Awlin flashed back. "You got in ahead of the rush!"

Horrocks tried for a moment to compose a thinkable reply, gave up, and zapped a

rude burst of static to the speculator. He hesitated over dropping the terrestrials,

looking hard at his portfolio. His claims in mercurials—the tiny planet near the sun

might someday be a power-beam construction site—were sound and edging

upward. Bids were coming in for time on the training habitat he'd just completed. He

could afford to gamble. He kept the claims.

2—Aeronautical Research

Darvin placed his chin on the strap in front of him, and slid his feet into the stirrups

behind him. The other straps of the harness pressed across his hips and the lower

part of his rib cage. Ropes from all of them converged to a hook in the ceiling. The

concrete floor was not far beneath him, but in this position it could be nothing but

too close. He forced himself to look straight ahead at the blank concrete wall. The

bright lights hurt his eyes. The glare was increased by reflection from the white paper

sheets crisscrossed with black ribbon tapes tacked to the wall on his right.

"Comfortable?" Orro asked, from off to his left.

"No!"

"Too bad. Oh well." The Gevorkian made some minute adjustment to the

tripod-mounted kinematographic apparatus over which he stooped. Apparently

satisfied, he looked up with an encouraging grin and a thumbs-up. His other thumb

was poised over the mo-tor switch.

"Ready?"

Darvin stretched out his wings and folded back his ears.

"Yes."

Thumbs went down, the switch clicked, clockwork whirred.

"Flap!" shouted Orro.

Darvin beat his wings up and down, imagining him-self in level flight, facing into an

imagined slipstream.

"Flap harder!"

Darvin realised he'd been subconsciously afraid of his wing tips hitting the floor.

They were in fact well clear. He flapped harder, almost rising out of the har-ness,

until a much faster flapping sound told him the reel of film had run out.

"All right, stop," said Orro. He dismounted the film from the camera, placed it in a

round flat can and la-belled it before stalking over to help Darvin out of the harness.

Orro's toe-claws, as usual overgrown, made scratching sounds on the floor that set

Darvin's teeth on edge.

"How did it look?" asked Darvin, folding his wings behind his elbows and flexing his

hands.

"A start," said Orro. "I can't say it looked terribly realistic, but at least I got half a

minute of wingbeats. We may have to try something else."

Darvin glanced sidelong at the harness. "As you say," he said, "a start."

He walked out of the test area and into the main part of the lab. The walls, in

between shelving, were almost covered with tacked-up pieces of paper scrawled

with calculations or sketches of several failed designs. The long table was cluttered

with hand tools, among the crumpled wings, smashed noses and cannibalised

en-gines of at least a dozen crashed model chiropters. The smells of wood glue and

solder hung over it like a mi-asma. In a corner lay the engine nacelle of a dirigible.

The propeller was as wide as a human wingspan. Gods knew from where Orro had

scrounged that piece of ex-pensive junk. A fugitive thought stirred in Darvin's mind

as he gazed at it. Then the insight, whatever it had been, was gone. He shook his

head. No doubt it would come back. He had a vague disquiet at the prospect.

"When do I see the result?" he asked.

Orro straightened, thrusting the can into his belt satchel. "Tomorow," he said. "If I

take it straight to the development lab."

"Oh," said Darvin. He had forgotten that part of the kinematographic process. "All

right. Give me a bell when you get it back."

"Of course," said Orro. His face brightened. "It is just a start, but it's a historic

start."

"I wouldn't want to miss it," Darvin said, as they left the lab. Orro locked the door.

The frosted wired glass bore, in barbed Gevorkian script, the legend Depart-ment of

Aeronautical Research. KEEP OUT. There was no Department of Aeronautical

Research, and Orro had not known that Gevorkian script was, in the cartoons and

playbills of Seloh's Reach, a conventional signifier of the at once scientific and

sinister. Probably, Darvin reflected, he still didn't. The exiled physicist still af-fected

surprise at encountering journals and discourses written in Selohic.

At the end of the corridor the two scientists paused at the ledge.

"See you tomorrow, then," said Darvin.

Orro nodded. "Or tonight, perhaps."

"Perhaps," said Darvin, with mild surprise. No doubt the usually sombre Gevorkian

felt he had some-thing to celebrate. "After you," he added.

Orro nodded again and stepped to the edge. He raised his arms and unfolded his

wings and dived forward, swooping away down about a hundred feet and banking

around and back in to the lower floor where the technical labs were located. Darvin

sprang harder from the ledge and with vigorous downbeats lifted himself higher,

rid-ing the Physics Building's updraft and soaring over the Modern Languages

Tower, on whose flat roof idle stu-dents sunned themselves or groomed each other.

He climbed higher; the midafternoon air was static and hot, caught between the sea

and the mountains, from which the morning and evening breezes respectively came.

Over the town it was trapped between the beach and the cliffs. Darvin ascended a

few hundred feet to clifftop height, catching a cooler current as he gazed across

miles of yellow grassland to the deeper ochre of the higher cliffs that marked the

broader tableland of the ul-terior. Pylons bearing transport and telephone cables

marched across that distance like a single file of giants. Prey herds grazed the grass,

great patches of dark like the shadows of absent clouds, clustered around the

wa-terways that meandered across the plain to tumble into the five ravines which

gave the town its name.

He wheeled. The blue of the Broad Channel re-freshed his sight as much as the high

air cooled his skin. Sullied by steamship smoke, spotted by the black of sails, the

Channel was still an immense and sooth-ing body of water which even at this height

went clear to the horizon. Darvin wondered whether Orro ever climbed high

enough—thousands of feet—to see all the way across it to the Realm of Gevork. It

struck him as unlikely. Nostalgia, to the best of Darvin's knowl-edge, was not among

his colleague's pains. Glancing upward, to that fancied height, Darvin noted the dark

speck of a dirigible of Seloh's Right, patient in its pa-trol. An obscure sense that he

had trespassed troubled him. It was not a feeling he associated with, or wished to

have in, the sky. He dropped.

From the top of his downward spiral, Five Ravines looked like a freak regular

woodland, a vast elabora-tion of an abandoned enclosure on the grasslands where

trees sprouted because their saplings could not be cropped by the prey. Trees lined

its streets and filled its parks and gardens: fruit trees for the most part, not so much

from deliberate planting as from seeds spat or (in ruder times) shat by people on the

wing. Trudges hauled carts along the streets, here and there making way for the

noisy, fuming motor vehicles. The town was divided by the watercourses of the

rivers from the ravines, united by its roads and bridges and sky-wires. The ravines

converged, the streams diverged; from a sufficient height they showed a pattern like

outspread wings. Expensive roosting and offices covered the ver-dant cliffs of the

ravines; cheaper and more recent buildings crowded the riversides to the shore, like

wooden gulleys. Among such were the university's faculties and departments; its

charter, centuries old, was younger by far than that of the borough.

Darvin's own office was in the Faculty of Impracti-cal Sciences, whose five-floor

wooden building was little different from the town roosts on either side of it. Darvin

skimmed the topmost branches of one of the street's trees and swooped to the

fourth-floor landing platform signboarded University of Five Ravines. De-partment

of Astronomy. Sweating and panting from his exertions and the renewed heat, he

strolled to the entranceway's array of wicker baskets and checked his post. A broad

and thick package awaited him. He hefted it with satisfaction as he hurried to his

room. An eight-nights' worth of photographic plates, despatched from the

observatory in the high desert. Each night usually afforded at least eight plates.

Checking them all could take up most of his working time for eight days, and then

the next set would arrive by the cable-car post, just as impatiently awaited.

A year's accumulation of such packages and their plates made up a small proportion
