Oceanic

  Their days were full of small challenges, and small discoveries. To cross a mountain range required skill and judgment as well as stamina; to understand the origins of each wind-blasted outcrop took careful observation and a strong visual imagination, as well as a grasp of the basic geological principles.

  Still, even as they clambered down one treacherous, powdery cliff-face, Ikat wondered soberly if they’d reached the high-tide mark of human exploration. The Orchid Seed’s modest speed and reach had never been exceeded; the giant telescopes had found no hints of life out to a hundred light years, offering little motivation to launch a new probe. The shift to software was becoming cheaper every year, and if that made travel to the stars easier, there were a thousand more alluring destinations closer to home. When you could pack a lifetime of exotic experiences into a realtime hour, capped off with happiness by fiat, who would give up decades of contemporaneity to walk on a distant world? There were even VR games, based on telescope imagery, where people fought unlikely wars with implausible alien empires on the very ground she was treading.

  “What are you planning to do when you get home?” she asked Qing that night. They had brought nothing with them from the base camp, so they simply slept on the ground beneath the stars.

  “Back to work, I suppose.” He ran his own successful engineering consultancy; so successful that it didn’t really need him. “What else is there? I’m not interested in crawling up a computer’s arse and pretending that I’ve gone to heaven. What about you?”

  “I don’t know. I was retired, happily enough. Waiting for death, I suppose.” It hadn’t felt like that, though.

  Qing said, “These aren’t the highest mountains on the planet, you know. The ones we’ve just crossed.”

  “I know that.”

  “There are some that reach into a pretty good vacuum.”

  Duty’s atmosphere was thin even on the ground; Ikat had no reason to doubt this assertion. “What’s your point?” she asked.

  He turned to her, and gave her his strangest robot smile. “From a mountain like that, a coil gun could land a package of nanomachines on Patience.”

  Patience was a third the mass of Duty, and had no atmosphere to speak of. “To what end?”

  Qing said, “High vacuum, relativistic launch speeds. What we started doesn’t have to stop here.”

  She searched his face, unsure if he was serious. “Do you think the Flower would give us what we needed? Who knows how Khamoush have programmed it?”

  “I tested the nanoware, back on Procellarum. I know how to make it give us whatever we ask.”

  Ikat thought it over. “Do we know how to describe everything we’ll need? To identify a new target? Plan a whole new mission?” The Orchard Seed had taken thousands of people decades to prepare.

  Qing said, “We’ll need telescopes, computing resources. We can bootstrap our way up, step by step. Let’s see how far we get in three months. And if we solve all the other problems, maybe we can go one step further: build a seed that will self-replicate when it reaches its destination, launching a couple of new seeds of its own.”

  Ikat rose to her feet angrily. “Not if you want my help! We have no right to spew mindless replicators in all directions. If someone from Earth wants to follow the seed we launch, and if they make their own decision when they get there to reach out further, then that’s one thing, but I’m not starting any kind of self-sustaining chain reaction that colonizes the galaxy while everyone sits at home playing VR games.”

  Qing stood up, and made a calming gesture. “All right, all right! I was just thinking out loud. The truth is, we’ll be struggling to launch anything before it’s time to go home. But better to try, than spend three months taking in the scenery.”

  Ikat remained wary for a moment, then she laughed with relief. “Absolutely. Let the real geologists back on Earth fret about these rocks; I’ve had enough of them already for a lifetime.”

  They didn’t wait for dawn; they headed back for the base camp immediately.

  As they approached the mountains, Qing said, “I thought it would give me some great sense of accomplishment, to come here and see with my own eyes that this thing I helped to start was finally complete. But if I could wish my descendants one blessing now, it would be never to see the end, never to find completion.”

  Ikat stopped walking, and mimed a toast. “To the coming generations. May they always start something they can’t finish.”

  SINGLETON

  2003

  I was walking north along George Street toward Town Hall railway station, pondering the ways I might solve the tricky third question of my linear algebra assignment, when I encountered a small crowd blocking the footpath. I didn’t give much thought to the reason they were standing there; I’d just passed a busy restaurant, and I often saw groups of people gathered outside. But once I’d started to make my way around them, moving into an alley rather than stepping out into the traffic, it became apparent that they were not just diners from a farewell lunch for a retiring colleague, putting off their return to the office for as long as possible. I could see for myself exactly what was holding their attention.

  Twenty meters down the alley, a man was lying on his back on the ground, shielding his bloodied face with his hands, while two men stood over him, relentlessly swinging narrow sticks of some kind. At first I thought the sticks were pool cues, but then I noticed the metal hooks on the ends. I’d only ever seen these obscure weapons before in one other place: my primary school, where an appointed window monitor would use them at the start and end of each day. They were meant for opening and closing an old-fashioned kind of hinged pane when it was too high to reach with your hands.

  I turned to the other spectators. “Has anyone called the police?” A woman nodded without looking at me, and said, “Someone used their mobile, a couple of minutes ago.”

  The assailants must have realized that the police were on their way, but it seemed they were too committed to their task to abandon it until that was absolutely necessary. They were facing away from the crowd, so perhaps they weren’t entirely reckless not to fear identification. The man on the ground was dressed like a kitchen hand. He was still moving, trying to protect himself, but he was making less noise than his attackers; the need, or the ability, to cry out in pain had been beaten right out of him.

  As for calling for help, he could have saved his breath.

  A chill passed through my body, a sick cold churning sensation that came a moment before the conscious realization: I’m going to watch someone murdered, and I’m going to do nothing. But this wasn’t a drunken brawl, where a few bystanders could step in and separate the combatants; the two assailants had to be serious criminals, settling a score. Keeping your distance from something like that was just common sense. I’d go to court, I’d be a witness, but no one could expect anything more of me. Not when thirty other people had behaved in exactly the same way.

  The men in the alley did not have guns. If they’d had guns, they would have used them by now. They weren’t going to mow down anyone who got in their way. It was one thing not to make a martyr of yourself, but how many people could these two grunting slobs fend off with sticks?

  I unstrapped my backpack and put it on the ground. Absurdly, that made me feel more vulnerable; I was always worried about losing my textbooks. Think about this. You don’t know what you’re doing. I hadn’t been in so much as a fist fight since I was thirteen. I glanced at the strangers around me, wondering if anyone would join in if I implored them to rush forward together. But that wasn’t going to happen. I was a willowy, unimposing eighteen-year-old, wearing a T-shirt adorned with Maxwell’s Equations. I had no presence, no authority. No one would follow me into the fray.

  Alone, I’d be as helpless as the guy on the ground. These men would crack my skull open in an instant. There were half a dozen solid-looking office workers in their twenties in the crowd; if these weekend rugby players hadn’t felt competent t
o intervene, what chance did I have?

  I reached down for my backpack. If I wasn’t going to help, there was no point being here at all. I’d find out what had happened on the evening news.

  I started to retrace my steps, sick with self-loathing. This wasn’t Kristallnacht. There’d be no embarrassing questions from my grandchildren. No one would ever reproach me.

  As if that were the measure of everything.

  “Fuck it.” I dropped my backpack and ran down the alley.

  I was close enough to smell the three sweating bodies over the stench of rotting garbage before I was even noticed. The nearest of the attackers glanced over his shoulder, affronted, then amused. He didn’t bother redeploying his weapon in mid-stroke; as I hooked an arm around his neck in the hope of overbalancing him, he thrust his elbow into my chest, winding me. I clung on desperately, maintaining the hold even though I couldn’t tighten it. As he tried to prize himself loose, I managed to kick his feet out from under him. We both went down onto the asphalt; I ended up beneath him.

  The man untangled himself and clambered to his feet. As I struggled to right myself, picturing a metal hook swinging into my face, someone whistled. I looked up to see the second man gesturing to his companion, and I followed his gaze. A dozen men and women were coming down the alley, advancing together at a brisk walk. It was not a particularly menacing sight – I’d seen angrier crowds with peace signs painted on their faces – but the sheer numbers were enough to guarantee some inconvenience. The first man hung back long enough to kick me in the ribs. Then the two of them fled.

  I brought my knees up, then raised my head and got into a crouch. I was still winded, but for some reason it seemed vital not to remain flat on my back. One of the office workers grinned down at me. “You fuckwit. You could have got killed.”

  The kitchen hand shuddered, and snorted bloody mucus. His eyes were swollen shut, and when he laid his hands down beside him, I could see the bones of his knuckles through the torn skin. My own skin turned icy, at this vision of the fate I’d courted for myself. But if it was a shock to realize how I might have ended up, it was just as sobering to think that I’d almost walked away and let them finish him off, when the intervention had actually cost me nothing.

  I rose to my feet. People milled around the kitchen hand, asking each other about first aid. I remembered the basics from a course I’d done in high school, but the man was still breathing, and he wasn’t losing vast amounts of blood, so I couldn’t think of anything helpful that an amateur could do in the circumstances. I squeezed my way out of the gathering and walked back to the street. My backpack was exactly where I’d left it; no one had stolen my books. I heard sirens approaching; the police and the ambulance would be there soon.

  My ribs were tender, but I wasn’t in agony. I’d cracked a rib falling off a trail bike on the farm when I was twelve, and I was fairly sure that this was just bruising. For a while I walked bent over, but by the time I reached the station I found I could adopt a normal gait. I had some grazed skin on my arms, but I couldn’t have appeared too battered, because no one on the train looked at me twice.

  That night, I watched the news. The kitchen hand was described as being in a stable condition. I pictured him stepping out into the alley to empty a bucket of fish-heads into the garbage, to find the two of them waiting for him. I’d probably never learn what the attack had been about unless the case went to trial, and as yet the police hadn’t even named any suspects. If the man had been in a fit state to talk in the alley, I might have asked him then, but any sense that I was entitled to an explanation was rapidly fading.

  The reporter mentioned a student “leading the charge of angry citizens” who’d rescued the kitchen hand, and then she spoke to an eye witness, who described this young man as “a New Ager, wearing some kind of astrological symbols on his shirt”. I snorted, then looked around nervously in case one of my housemates had made the improbable connection, but no one else was even in earshot.

  Then the story was over.

  I felt flat for a moment, cheated of the minor rush that fifteen seconds’ fame might have delivered; it was like reaching into a biscuit tin when you thought there was one more chocolate chip left, to find that there actually wasn’t. I considered phoning my parents in Orange, just to talk to them from within the strange afterglow, but I’d established a routine and it was not the right day. If I called unexpectedly, they’d think something was wrong.

  So, that was it. In a week’s time, when the bruises had faded, I’d look back and doubt that the incident had ever happened.

  I went upstairs to finish my assignment.

  Francine said, “There’s a nicer way to think about this. If you do a change of variables, from x and y to z and z-conjugate, the Cauchy-Riemann equations correspond to the condition that the partial derivative of the function with respect to z-conjugate is equal to zero.”

  We were sitting in the coffee shop, discussing the complex analysis lecture we’d had half an hour before. Half a dozen of us from the same course had got into the habit of meeting at this time every week, but today the others had failed to turn up. Maybe there was a movie being screened, or a speaker appearing on campus that I hadn’t heard about.

  I worked through the transformation she’d described. “You’re right,” I said. “That’s really elegant!”

  Francine nodded slightly in assent, while retaining her characteristic jaded look. She had an undisguisable passion for mathematics, but she was probably bored out of her skull in class, waiting for the lecturers to catch up and teach her something she didn’t already know.

  I was nowhere near her level. In fact, I’d started the year poorly, distracted by my new surroundings: nothing so glamorous as the temptations of the night life, just the different sights and sounds and scale of the place, along with the bureaucratic demands of all the organizations that now impinged upon my life, from the university itself down to the shared house groceries subcommittee. In the last few weeks, though, I’d finally started hitting my stride. I’d got a part-time job, stacking shelves in a supermarket; the pay was lousy, but it was enough to take the edge off my financial anxieties, and the hours weren’t so long that they left me with no time for anything but study.

  I doodled harmonic contours on the notepaper in front of me. “So what do you do for fun?” I said. “Apart from complex analysis?”

  Francine didn’t reply immediately. This wasn’t the first time we’d been alone together, but I’d never felt confident that I had the right words to make the most of the situation. At some point, though, I’d stopped fooling myself that there was ever going to be a perfect moment, with the perfect phrase falling from my lips: something subtle but intriguing slipped deftly into the conversation, without disrupting the flow. So now I’d made my interest plain, with no attempt at artfulness or eloquence. She could judge me as she knew me from the last three months, and if she felt no desire to know me better, I would not be crushed.

  “I write a lot of Perl scripts,” she said. “Nothing complicated; just odds and ends that I give away as freeware. It’s very relaxing.”

  I nodded understandingly. I didn’t think she was being deliberately discouraging; she just expected me to be slightly more direct.

  “Do you like Deborah Conway?” I’d only heard a couple of her songs on the radio myself, but a few days before I’d seen a poster in the city announcing a tour.

  “Yeah. She’s great.”

  I started thickening the conjugation bars over the variables I’d scrawled. “She’s playing at a club in Surry Hills,” I said. “On Friday. Would you like to go?”

  Francine smiled, making no effort now to appear world-weary. “Sure. That would be nice.”

  I smiled back. I wasn’t giddy, I wasn’t moonstruck, but I felt as if I were standing on the shore of an ocean, contemplating its breadth. I felt the way I felt when I opened a sophisticated monograph in the library, and was reduced to savoring the scent of
the print and the crisp symmetry of the notation, understanding only a fraction of what I read. Knowing there was something glorious ahead, but knowing too what a daunting task it would be to come to terms with it.

  I said, “I’ll get the tickets on my way home.”

  To celebrate the end of exams for the year, the household threw a party. It was a sultry November night, but the back yard wasn’t much bigger than the largest room in the house, so we ended up opening all the doors and windows and distributing food and furniture throughout the ground floor and the exterior, front and back. Once the faint humid breeze off the river penetrated the depths of the house, it was equally sweltering and mosquito-ridden everywhere, indoors and out.

  Francine and I stayed close for an hour or so, obeying the distinctive dynamics of a couple, until by some unspoken mutual understanding it became clear that we could wander apart for a while, and that neither of us was so insecure that we’d resent it.

  I ended up in a corner of the crowded back yard, talking to Will, a biochemistry student who’d lived in the house for the last four years. On some level, he probably couldn’t help feeling that his opinions about the way things were run should carry more weight than anyone else’s, which had annoyed me greatly when I’d first moved in. We’d since become friends, though, and I was glad to have a chance to talk to him before he left to take up a scholarship in Germany.

  In the middle of a conversation about the work he’d be doing, I caught sight of Francine, and he followed my gaze.

  Will said, “It took me a while to figure out what finally cured you of your homesickness.”

  “I was never homesick.”

  “Yeah, right.” He took a swig of his drink. “She’s changed you, though. You have to admit that.”

  “I do. Happily. Everything’s clicked, since we got together.” Relationships were meant to screw up your studies, but my marks were soaring. Francine didn’t tutor me; she just drew me into a state of mind where everything was clearer.
