PART TWO Areophany

To Sax it looked like that least rational of conflicts, civil war. Two parts of a group shared many more interests than disagreements, but fought anyway. Unfortunately it was not possible to force people to study cost-benefit analysis. Nothing to be done. Or – possibly one could identify a crux issue causing one or both sides to resort to violence. After that, try to defuse that issue.

Clearly in this case a crux issue was terraforming. A matter with which Sax was closely identified. This could be viewed as a disadvantage, as a mediator ought ideally to be neutral. On the other hand, his actions might speak symbolically for the terraforming effort itself. He might accomplish more with a symbolic gesture than anyone else. What was needed was a concession to the Reds, a real concession, the reality of which would increase its symbolic value by some hidden exponential factor. Symbolic value: it was a concept with which Sax was trying hard to come to grips. Words of all kinds gave him trouble now, so much so that he had taken to etymology to try to understand them better. A glance at the wrist: symbol, ‘something that stands for something else’, from the Latin symbolum, adopted from a Greek word meaning throw together. Exactly. It was alien to his understanding, this throwing together, a thing emotional and even unreal, and yet vitally important.

The afternoon of the battle for Sheffield, he called Ann on the wrist and got her briefly, and tried to talk to her, and failed. So he drove to the edge of the city’s wreckage, not knowing what else to do, looking for her. It was very disturbing to see how much damage a few hours’ fighting could do. Many years of work lay in smoking shambles, the smoke not fire – ash particulates for the most part but merely disturbed fines, old volcanic ash blown up and then torn east on the Jetstream. The cable stuck out of the ruins like a black line of carbon nanotube fibres.

There was no sign of any further Red resistance. Thus no way of locating Ann. She was not answering her phone. So Sax returned to the warehouse complex in East Pavonis, feeling balked. He went back inside.

And then there she was, in the vast warehouse, walking through the others toward him as if about to plunge a knife in his heart. He sank in his seat unhappily, remembering an overlong sequence of unpleasant interviews between them. Most recently they had argued on the train ride out of Libya Station. He recalled her saying something about removing the soletta and the annular mirror; which would be a very powerful symbolic statement indeed. And he had never been comfortable with such a major element of the terraforming’s heat input being so fragile.

So when she said, ‘I want something for it,’ he thought he knew what she meant, and suggested removing the mirrors before she could. This surprised her. It slowed her down, it took the edge off her terrible anger. Leaving something very much deeper, however – grief, despair – he could not be sure. Certainly a lot of Reds had died that day, and Red hopes as well. ‘I’m sorry about Kasei,’ he said.

She ignored that, and made him promise to remove the space mirrors. He did, meanwhile calculating the loss of light that would result, then trying to keep a wince off his face. Insolation would drop by about twenty per cent, a very substantial amount indeed. ‘It will start an ice age,’ he muttered.

‘Good,’ she said.

But she was not satisfied. And as she left the room, he could see by the set of her shoulders that his concession had done little if anything to comfort her. One could only hope her cohorts were more easily pleased. In any case it would have to be done. It might stop a civil war. Of course a great number of plants would die, mostly at the higher elevations, though it would affect every ecosystem to some extent. An ice age, no doubt about it. Unless they reacted very effectively. But it would be worth it, if it stopped the fighting.

It would have been easy just to cut the great band of the annular mirror and let it fly away into space, right out of the plane of the ecliptic. Same with the soletta: fire a few of its positioning rockets and it would spin away like a Catherine wheel.

But that would be a waste of processed aluminium silicate, which Sax did not like to see. He decided to investigate the possibility of using the mirrors’ directional rockets, and their reflectivity, to propel them elsewhere in the solar system. The soletta could be located in front of Venus, and its mirrors realigned so that the structure became a huge parasol, shading the hot planet and starting the process of freezing out its atmosphere; this was something that had been discussed in the literature for a long time, and no matter what other plans for terraforming Venus one had, this was the standard first step. Then having done that, the annular mirror would have to be placed in the corresponding polar orbit around Venus, as its reflected light helped to hold the soletta/parasol in its position against the push of solar radiation. So the two would still be put to use, and it would also be a gesture, another symbolic gesture, saying, Look here – this big world might be terraformable too. It wouldn’t be easy, but it was possible. Thus some of the psychic pressure on Mars, ‘the only other possible Earth’, might be relieved. This was not logical, but it didn’t matter; history was strange, people were not rational systems, and in the peculiar symbolic logic of the limbic system, it would be a sign to the people on Earth, a portent, a scattering of psychic seed, a throwing together. Look there! Go there! And leave Mars alone.

So he talked it over with the Da Vinci space scientists, who had effectively taken over control of the mirrors. The lab rats, people called them behind their backs, and his (though he heard anyway); the lab rats, or the saxaclones. Serious young native Martian scientists, in fact, with just the same variations of temperament as grad students and post-docs in any lab anywhere, any time; but the facts didn’t matter. They worked with him and so they were the saxaclones. Somehow he had become the very model of the modern Martian scientist; first as white-coated lab rat, then as full-blown mad scientist, with a crater-castle full of eager Igors, mad-eyed but measured in manner, little Mr Spocks, the men as skinny and awkward as cranes on the ground, the women drab in their protective non-coloration, their neuter devotion to Science. Sax was very fond of them. He liked their devotion to science, it made sense to him – an urge to understand things, to be able to express them mathematically. It was a sensible desire. In fact it often seemed to him that if everyone were a physicist then they would be very much better off. ‘Ah, no, people like the idea of a flat universe because they find negatively curved space difficult to deal with.’ Well, perhaps not. In any case the young natives at Da Vinci Crater were a powerful group, strange or not. At this point Da Vinci was in charge of a lot of the underground’s technological base, and with Spencer fully engaged there, their production capability was staggering. They had engineered the revolution, if the truth were told, and were now in de facto control of Martian orbital space.

This was one reason why many of them looked displeased or at least nonplussed when Sax first told them about the removal of the soletta and annular mirror. He did it in a screen meeting, and their faces squinched into expressions of alarm: Captain, it is not logical. But neither was civil war. And the one was better than the other.

‘Won’t people object?’ Aonia asked. ‘The Greens?’

‘No doubt,’ Sax said. ‘But right now we exist in, in anarchy. The group in East Pavonis is a kind of proto-government, perhaps. But we in Da Vinci control Mars space. And no matter the objections, this might avert civil war.’

He explained as best he could. They got absorbed in the technical challenge, in the problem pure and simple, and quickly forgot their shock at the idea. In fact giving them a technical challenge of that sort was like giving a dog a bone. They went away gnawing at the tough parts of the problem, and just a few days later they were down to the smooth polished gleam of procedure. Mostly a matter of instructions to AIs, as usual. It was getting to the point where having conceived a clear idea of what one wanted to do, one could just say to an AI, ‘please do thus and such’ – please spin the soletta and annular mirror into Venusian orbit, and adjust the slats of the soletta so that it becomes a parasol shielding the planet from all of its incoming insolation; and the AIs would calculate the trajectories and the rocket firings and the mirror angles necessary, and it would be done.

People were becoming too powerful, perhaps. Michel always went on about their godlike new powers, and Hiroko in her actions had implied that there should be no limit to what they tried with these new powers, ignoring all tradition. Sax himself had a healthy respect for tradition, as a kind of default survival behaviour. But the techs in Da Vinci cared no more for tradition than Hiroko had. They were in an open moment in history, accountable to no one. And so they did it.

Then Sax went to Michel. ‘I’m worried about Ann.’

They were in a corner of the big warehouse on East Pavonis, and the movement and clangour of the crowd created a kind of privacy. But after a look around Michel said, ‘Let’s go outside.’

They suited up and went out. East Pavonis was a maze of tents, warehouses, manufactories, pistes, parking lots, pipelines, holding tanks, holding yards; also junkyards and scrap-heaps, their mechanical detritus scattered about like volcanic ejecta. But Michel led Sax westward through the mess, and they came quickly to the caldera rim, where the human clutter was put into a new and larger context, a logarithmic shift that left the pharaonic collection of artefacts suddenly looking like a patch of bacterial growth.

At the very edge of the rim, the blackish speckled basalt cracked down in several concentric ledges, each lower than the last. A set of staircases led down these terraces, and the lowest was railed. Michel led Sax down to this terrace, where they could look over the side into the caldera. Straight down for five kilometres. The caldera’s large diameter made it seem less deep than that; still it was an entire round country down there, far, far below. And when Sax remembered how small the caldera was proportional to the volcano entire, Pavonis itself seemed to bulk under them like a conical continent, rearing right up out of the planet’s atmosphere into low space. Indeed the sky was only purple around the horizon, and blackish overhead, with the sun a hard gold coin in the west, casting clean, slantwise shadows. They could see it all. The fines thrown up by the explosions were gone, everything returned to its normal telescopic clarity. Stone and sky and nothing more – except for the thread of buildings cast around the rim. Stone and sky and sun. Ann’s Mars. Except for the buildings. And on Ascraeus and Arsia and Elysium, and even on Olympus, the buildings would not be there.

‘We could easily declare everything above about eight kilometres a primal wilderness zone,’ Sax said. ‘Keep it like this forever.’

‘Bacteria?’ Michel asked. ‘Lichen?’

‘Probably. But do they matter?’

‘To Ann they do.’

‘But why. Michel? Why is she like that?’

Michel shrugged.

After a long pause he said, ‘No doubt it is complex. But she was mistreated as a girl, did you know that?’

Sax shook his head. He tried to imagine what that meant.

Michel said, ‘Her father died. Her mother married her stepfather when she was eight. From then on he mistreated her, until she was sixteen, when she moved to the mother’s sister. I’ve asked her what the mistreatment consisted of, but she says she doesn’t want to talk about it. Abuse is abuse, she said. She doesn’t remember much anyway, she says.’

‘I believe that.’

Michel waggled a gloved hand. ‘We remember more than we think we do. More than we want to, sometimes.’

They stood there looking into the caldera.

‘It’s hard to believe,’ Sax said.

Michel looked glum. ‘Is it? There were fifty women in the First Hundred. Odds are more than one of them was abused by men in their lives. More like ten or fifteen, if the statistics are to be believed. Sexually violated, struck, mistreated … that’s just the way it was.’

‘It’s hard to believe.’

‘Yes.’

Sax recalled hitting Phyllis in the jaw, knocking her senseless with a single blow. There had been a certain satisfaction in that. He had needed to do it, though. Or so it had felt at the time.

‘Everyone has their reasons’ Michel said, startling him. ‘Or so they think.’ He tried to explain – tried, in his usual Michel fashion, to make it something other than plain evil. ‘At the base of human culture,’ he said as he looked down into the country of the caldera, ‘is a neurotic response to people’s earliest psychic wounds. Before birth and during infancy people exist in a narcissistic oceanic bliss, in which the individual is the universe. Then some time in late infancy we come to the awareness that we are separate individuals, different from our mother and everyone else. This is a blow from which we never completely recover. There are several neurotic strategies used to try to deal with it. First, merging back into the mother. Then denying the mother, and shifting our ego ideal to the father – this strategy often lasts forever, and the people of that culture worship their king and their father god, and so on. Or the ego ideal might shift again, to abstract ideas, or to the brotherhood of men. There are names and full descriptions for all these complexes – the Dionysian, the Persean, the Apollonian, the Heraclean. They all exist, and they are all neurotic, in that they all lead to misogyny, except for the Dionysian complex.’

‘This is one of your semantic rectangles?’ Sax asked apprehensively.

‘Yes. The Apollonian and the Heraclean complexes might describe Terran industrial societies. The Persean its earlier cultures, with strong remnants of course right up to this day. And they are all three patriarchal. They all denied the maternal, which was connected in patriarchy with the body and with nature. The feminine was instinct, the body, and nature; while the masculine was reason, mind, and law. And the law ruled.’

Sax, fascinated by so much throwing together, said only, ‘And on Mars?’

‘Well, on Mars it may be that the ego ideal is shifting back to the maternal. To the Dionysian again, or to some kind of post-Oedipal reintegration with nature, which we are still in the process of inventing. Some new complex that would not be so subject to neurotic over-investment.’

Sax shook his head. It was amazing how floridly elaborated a pseudo-science could get. A compensation technique, perhaps; a desperate attempt to be more like physics. But what they did not understand was that physics, while admittedly complicated, was always trying very hard to become simpler.

Michel, however, was continuing to elaborate. Correlated to patriarchy was capitalism, he was saying, a hierarchical system in which most men had been exploited economically, also treated like animals, poisoned, betrayed, shoved around, shot. And even in the best of circumstances under constant threat of being tossed aside, out of a job, poor, unable to provide for loved dependants, hungry, humiliated. Some trapped in this unfortunate system took out their rage at their plight on whomever they could, even if that turned out to be their loved ones, the people most likely to give them comfort. It was illogical, and even stupid. Brutal and stupid. Yes. Michel shrugged; he didn’t like where this train of reasoning had led him. It sounded to Sax as if the implication was that many men’s actions indicated that they were, alas, fairly stupid. And the limbic array got all twisted in some minds, Michel was going on, trying to veer away from that, to make a decent explanation. Adrenalin and testosterone were always pushing for a fight-or-flight response, and in some dismal situations a satisfaction circuit got established in the get hurt/hurt back axis, and then the men involved were lost, not only to fellow feeling but to rational self-interest. Sick, in fact.

Sax felt a little sick himself. Michel had explained away male evil in several different ways in no more than a quarter of an hour, and still the men of Earth had a lot to answer for. Marsmen were different. Although there had been torturers in Kasei Vallis, as he well knew. But they had been settlers from Earth. Sick. Yes, he felt sick. The young natives were not like that, were they? A Marsman who hit a woman or molested a child would be ostracized, excoriated, perhaps beaten up, he would lose his home, he would be exiled to the asteroids and never allowed back. Wouldn’t he?

Something to look into.

Now he thought again of Ann. Of how she was: her manner, so obdurate; her focus on science, on rock. A kind of Apollonian response, perhaps. Concentration on the abstract, denial of the body and therefore of all its pain. Perhaps.

‘What would help Ann now, do you think?’ Sax said.

Michel shrugged again. ‘I have wondered that for years. I think Mars has helped her. I think Simon helped her, and Peter. But they have all been at some kind of distance. They don’t change that fundamental no in her.’

‘But she – she loves all this,’ Sax said, waving at the caldera. ‘She truly does.’ He thought over Michel’s analysis. ‘It’s not just a no. There’s a yes in there as well. A love of Mars.’

‘But if you love stones and not people,’ Michel said, ‘it’s somehow a little … unbalanced? Or displaced? Ann is a great mind, you know—’

‘I know—’

‘—and she has achieved a great deal. But she does not seem content with it.’

‘She doesn’t like what’s happening to her world.’

‘No. But is that what she truly dislikes? Or dislikes the most? I’m not so sure. It seems displaced to me, again. Both the love and the hate.’

Sax shook his head. Astounding, really, that Michel could consider psychology any kind of science at all. So much of it consisted of throwing together. Of thinking of the mind as a steam engine, the mechanical analogy most ready to hand during the birth of modern psychology. People had always done that when they thought about the mind: clockwork for Descartes, geological changes for the early Victorians, computers or holography for the twentieth century, AIs for the twenty-first … and for the Freudian traditionalists, steam engines. Application of heat, pressure build-up, pressure displacement, venting, all shifted into repression, sublimation, the return of the repressed. Sax thought it unlikely steam engines were an adequate model for the human mind. The mind was more like – what? – an ecology – a fellfield – or else a jungle, populated by all manner of strange beasts. Or a universe, filled with stars and quasars and black holes. Well – a bit grandiose, that – really it was more like a complex collection of synapses and axons, chemical energies surging hither and yon, like weather in an atmosphere. That was better – weather-storm fronts of thought, high pressure zones, low pressure cells, hurricanes – the jetstreams of biological desires, always making their swift powerful rounds … life in the wind. Well. Throwing together. In fact the mind was poorly understood.

‘What are you thinking?’ Michel asked.

‘Sometimes I worry,’ Sax admitted, ‘about the theoretical basis of these diagnoses of yours.’

‘Oh no, they are very well supported empirically, they are very precise, very accurate.’

‘Both precise and accurate?’

‘Well, what, they’re the same, no?’

‘No. In estimates of a value, accuracy means how far away you are from the true value. Precision refers to the window size of the estimate. A hundred plus or minus fifty isn’t very precise. But if your estimate is a hundred plus or minus fifty, and the true value is a hundred and one, it’s quite accurate, while still being not very precise. Often true values aren’t really determinable, of course.’

Michel had a curious expression on his face. ‘You’re a very accurate person, Sax.’

‘It’s just statistics,’ Sax said defensively. ‘Every once in a while language allows you to say things precisely.’

‘And accurately.’

‘Sometimes.’

They looked down into the country of the caldera.

‘I want to help her,’ Sax said.

Michel nodded. ‘You said that. I said I didn’t know how. For her, you are the terraforming. If you are to help her, then terraforming has to help her. Do you think you can find a way that terraforming helps her?’

Sax thought about it for a while. ‘It could get her outdoors. Outdoors without helmets, eventually without even masks.’

‘You think she wants that?’

‘I think everyone wants that, at some level. In the cerebellum. The animal, you know. It feels right.’

‘I don’t know if Ann is very well attuned to her animal feelings.’

Sax considered it.

Then the whole landscape darkened.

They looked up. The sun was black. Stars shone in the sky around it. There was a faint glow around the black disc, perhaps the sun’s corona.

Then a sudden crescent of fire forced them to look away. That was the corona; what they had seen before had probably been the lit exosphere.

The darkened landscape lightened again, as the artificial eclipse came to an end. But the whole sun that returned was distinctly smaller than what had shone just moments before. The old bronze button of the Martian sun! It was like a friend come back for a visit. The world was dimmer, all the colours of the caldera one shade darker, as if invisible clouds obscured the sunlight. A very familiar sight, in fact – Mars’s natural light, shining on them again for the first time in twenty-eight years.

‘I hope Ann saw that,’ Sax said. He felt chilled, although he knew there had not been enough time for the air to have cooled, and he was suited up in any case. But there would be a chill. He thought grimly of the fellfields scattered all over the planet, up at the four or five kilometre elevation, and lower in the mid and high latitudes. Up at the edge of the possible, whole ecosystems would now start dying. Twenty per cent drop in insolation: it was worse than any Terran ice age, more like the darkness after the great extinction events – the KT event, the Ordovician, the Devonian, or the worst one of all, the Permian event two hundred and fifty million years ago, which killed up to ninety-five per cent of all the species alive at the time. Punctuated equilibrium; and very few species survived the punctuations. The ones that did were tough, or just lucky.

Michel said, ‘I doubt it will satisfy her.’

This Sax fully believed. But for the moment he was distracted by thinking how best to compensate for the loss of the soletta’s light. It would be better not to have any biomes suffering great losses. If he had his way, those fellfields were just something Ann was going to have to get used to.

It was Ls 123, right in the middle of the northern summer/southern winter, near aphelion, which along with higher elevation caused the south’s winter to be much colder than the north’s; temperatures regularly dipped to 230° K, not much warmer than the primal colds that had existed before their arrival. Now, with the soletta and annular mirror gone, temperatures would drop further still. No doubt the southern highlands were headed for a record winterkill.

On the other hand, a lot of snow had already fallen in the south, and Sax had gained a great respect for snow’s ability to protect living things from cold and wind. The subnivean environment was quite stable. It could be that a drop in light, and subsequently in surface temperature, would not do that much harm to snowed-over plants, already shut down by their winter hardening. It was hard to say. He wanted to get into the field and see for himself. Of course it would be months or perhaps years before any difference would be quantifiable. Except in the weather itself, perhaps. And weather could be tracked merely by watching the meteorological data, which he was already doing spending many hours in front of satellite pictures and weather maps, watching for signs. As were many other people, particularly meteorologists. It made for a useful diversion when people came by to remonstrate with him for removing the mirrors, an event so common in the week following the event that it became tiresome.

Unfortunately weather on Mars was so variable that it was difficult to tell if the removal of the big mirrors was affecting it or not. A very sad admission of the state of their understanding of the atmosphere, in Sax’s opinion. But there it was. Martian weather was a violent, semi-chaotic system. In some ways it resembled Earth’s, not surprising given that it was a matter of air and water moving around the surface of a spinning sphere: Coriolis forces were the same everywhere, and so here as on Earth there were tropical easterlies, temperate westerlies, polar easterlies, Jetstream anchor points and so on; but that was almost all one could say for sure about Martian weather. Well – you could say that it was colder and drier in the south than in the north. That there were rainshadows downwind of high volcanoes or mountain chains. That it was warmer near the equator, colder at the poles. But this sort of obvious generalization was all that they could assert with confidence, except for some local patterns, although most of those were subject to lots of variation – more a matter of highly analysed statistics than lived experience. And with only fifty-two M-years on record, with the atmosphere thickening radically all the while, with water being pumped onto the surface, etc, etc, it was actually fairly difficult to say what normal or average conditions might be.

Meanwhile, Sax found it hard to concentrate there on East Pavonis. People kept interrupting him to complain about the mirrors, and the volatile political situation lurched along in storms as unpredictable as the weather’s. Already it was clear that removing the mirrors had not placated all the Reds; there were sabotages of terraforming projects almost every day, and sometimes violent fights in defence of these projects. And reports from Earth, which Sax forced himself to watch for an hour a day, made it clear that some forces there were trying to keep things the way they had been before the flood, in sharp conflict with other groups trying to take advantage of the flood in the same way the Martian revolutionaries had, using it as a break point in history and a springboard to some new order, some fresh start. But the metanationals were not going to give up easily, and on Earth they were entrenched, the order of the day; they were in command of vast resources, and no mere seven-metre rise in sea level was going to push them off stage.

Sax switched off his screen after one such depressing hour, and joined Michel for supper out in his rover.

‘There’s no such thing as a fresh start,’ he said as he put water on to boil.

‘The Big Bang?’ Michel suggested.

‘As I understand it, there are theories suggesting that the – the dumpiness of the early universe was caused by the earlier-dumpiness of the previous universe, collapsing down into its Big Crunch.’

‘I would have thought that would crush all irregularities.’

‘Singularities are strange – outside their event horizons, quantum effects allow some particles to appear. Then the cosmic inflation blasting those particles out apparently caused small clumps to start and become big ones.’ Sax frowned; he was sounding like the Da Vinci theory group. ‘But I was referring to the flood on Earth. Which is not as complete an alteration of conditions as a singularity, by any means. In fact there must be people down there who don’t think of it as a break at all.’

‘True.’ For some reason Michel was laughing. ‘We should go down there and see, eh?’

As they finished eating their spaghetti Sax said, ‘I want to get out in the field. I want to see if there are any visible effects of the mirrors going away.’

‘You already saw one. That dimming of the light, when we were out on the rim …’ Michel shuddered.

‘Yes, but that only makes me more curious.’

‘Well – we’ll hold down the fort for you.’

As if one had physically to occupy any given space in order to be there. ‘The cerebellum never gives up,’ Sax said.

Michel grinned. ‘Which is why you want to go out and see it in person.’

Sax frowned.

Before he left, he called Ann.

‘Would you like to, to accompany me, on a trip to South Tharsis, to, to, to examine the upper boundary of the areobio-sphere, together?’

She was startled. Her head was shaking back and forth as she thought it over – the cerebellum’s answer, some six or seven seconds ahead of her conscious verbal response: ‘No.’ And then she cut the connection, looking somewhat frightened.

Sax shrugged. He felt bad. He saw that one of his reasons for going into the field had to do with getting Ann out there, showing her the fellfields himself. Showing her how beautiful they were. Talking to her. Something like that. His mental image of what he would say to her if he actually got her out there was fuzzy at best. Just show her. Make her see it.

Well, one couldn’t make people see things.

He went to say goodbye to Michel. Michel’s entire job was to make people see things. This was no doubt the cause of the frustration in him when he talked about Ann. She had been one of his patients for over a century now and still she hadn’t changed, or even told him very much about herself. It made Sax smile a little to think of it. Though clearly it was vexing for Michel, who obviously loved Ann. As he did all his old friends and patients, including Sax. It was in the nature of a professional responsibility, as Michel saw it – to fall in love with all the objects of his ‘scientific study’. Every astronomer loves the stars. Well, who knew. Sax reached out and clasped Michel’s upper arm, who smiled happily at this unSaxlike behaviour, this ‘change in thinking’. Love, yes; and how much more so when the object of study consisted of women known for years and years, studied with the intensity of pure science – yes, that would be a feeling. A great intimacy, whether they co-operated in the study or not. In fact they might even be more beguiling if they didn’t co-operate, if they refused to answer any questions at all. After all if Michel wanted questions answered, answered at great length even when they weren’t asked, he always had Maya, Maya the all-too-human, who led Michel on a hard steeplechase across the limbic array, including throwing things at him, if Spencer was to be believed. After that kind of symbolism, the silence of Ann might prove to be very endearing. ‘Be careful,’ Michel said: the happy scientist, with one of his areas of study standing before him, loved like a brother.
