СКАЧАТЬ bond dissociation energy.”

      “But why?”

      Blinking ever harder: “Well, that’s just a matter of physics.” He diagrammed vigorously on the blackboard: “Covalent bonds are formed when two atomic orbitals merge to form a single bond orbital, occupied by electrons from both atoms. Breaking the bond releases thirty to a hundred k cals of stored energy.”

      Several of them asked, in chorus, “But why?”

      This got him into sub-atomic physics, where the chain of whys and becauses could go on for a half hour without him ever once saying something they could understand. Finally they would sense they were near the endgame. “But why?”

      “Well,” beginning to go cross-eyed, “atoms want to get to their stable number of electrons, and they’ll share electrons when they have to.”

      “But why?”

      Now he was looking trapped. “That’s just the way atoms bond. One of the ways.”

      “But WHY?”

      A shrug. “That’s how the atomic force works. That’s how things came out—”

      And they all would shout, “in the Big Bang!”

      They would howl with glee, and Sax’s forehead would knot up as he realised that they had done it to him again. He would sigh, and go back to where he had been when the game began. But every time they started it again, he never seemed to remember, as long as the initial why was plausible enough. And even when he did recognise what was happening, he seemed helpless to stop it. His only defence was to say, with a little frown, “Why what?” That slowed the game for a while; but then Nirgal and Jackie got clever at guessing what in any statement most deserved a why, and as long as they could do that, Sax seemed to feel it was his job to continue answering, right on up the chains of because to the Big Bang, or, every once in a while, to a muttered “We don’t know.”

      “We don’t know!” the class would exclaim in mock dismay. “Why not?”

      “It’s not explained,” he would say, frowning. “Not yet.”

      And so the good mornings with Sax would pass; and both he and the kids seemed to agree that these were better than the bad mornings, when he would drone on uninterrupted, and protest, “This is really a very important matter” as he turned from the blackboard and saw a crop of heads laid out snoring on the desktops.

      One morning, thinking about Sax’s frown, Nirgal stayed behind in the school until he and Sax were the only ones left, and then he said, “Why don’t you like it when you can’t say why?”

      The frown returned. After a long silence Sax said slowly, “I try to understand. I pay attention to things, you see, very closely. As closely as I can. Concentrating on the thisness of every moment. And I want to understand why it happens the way it does. I’m curious. And I think that everything happens for a reason. Everything. So, we should be able to tease these reasons out. When we can’t … well, I don’t like it. It vexes me. Sometimes I call it—” he glanced at Nirgal shyly, and Nirgal saw that he had never told this to anyone before— “I call it the great unexplainable.”

      It was the white world, Nirgal saw suddenly. The white world inside the green, the opposite of Hiroko’s green world inside the white. And they had opposite feelings about them. Looking from the green side, when Hiroko confronted something mysterious, she loved it and it made her happy—it was viriditas, a holy power. Looking from the white side, when Sax confronted something mysterious, it was the Great Unexplainable, dangerous and awful. He was interested in the true, while Hiroko was interested in the real. Or perhaps it was the other way around—those words were tricky. Better to say she loved the green world, he the white.

      “But yes!” Michel said when Nirgal mentioned this observation to him. “Very good, Nirgal. Your sight has such insight. In archetypal terminologies we might call green and white the Mystic and the Scientist. Both extremely powerful figures, as you see. But what we need, if you ask me, is a combination of the two, which we call the Alchemist.”

      The green and the white.

      Afternoons the children were free to do what they wanted, and sometimes they stayed with the day’s teacher, but more often they ran on the beach or played in the village, which lay nestled in its cluster of low hills, halfway between the lake and the tunnel entrance. They climbed the spiralling staircases of the big bamboo treehouses, and played hide and seek among the stacked rooms and the daughter shoots and the hanging bridges connecting them. The bamboo dorms made a crescent which held most of the rest of the village inside it; each of the big shoots was five or seven segments high, each segment a room, getting smaller as they got higher. The children each had rooms of their own in the top segments of the shoots—windowed vertical cylinders that were four or five steps across, like the towers of the castles in their stories. Below them in the middle segments the adults had their rooms, mostly alone but sometimes in couples; and the bottom segments were living rooms. From the windows of their top rooms they looked down on the village rooftops, clustered in the circle of hills and bamboo and greenhouses like mussels in the lake shallows.

      On the beach they hunted shells or played German dodgeball, or shot arrows across the dunes into blocks of foam. Usually Jackie and Dao chose the games, and led the teams if there were teams. Nirgal and the younger ones followed them, cycling through their various friendships and hierarchies, which were honed endlessly in the daily play. As little Frantz once crudely explained it to Nadia, “Dao hits Nirgal; Nirgal hits me; I hit the girls.” Often Nirgal got tired of that game, which Dao always won, and for better fun he would take off running around the lake, slowly and steadily, falling into a rhythm which seemed to encompass everything in the world. He could circle the lake for as long as the day lasted when he got in that rhythm. It was a joy, an exhilaration.

      Under the dome it was always cold, but the light was perpetually changing. In summer the dome glowed bluish white all the time, and pencils of lit air stood under the skylight shafts. In winter it was dark, and the dome flared with reflected lamplight, like the inside of a mussel shell. In spring and autumn the light would dim in the afternoon to a grey and ghostly dusk, the colours only suggested by the many shades of grey, the bamboo leaves and pine needles all ink strokes against the faint white of the dome. In those hours the greenhouses were like big fairy lamps on the hills, and the kids would wander home criss-crossing like gulls, and head for the bathhouse. There in the long building beside the kitchen they would pull off their clothes and run into the steamy clangour of the big main bath, sliding around on the bottom tiles feeling heat buzz back into their hands and feet and faces as they splashed friskily around the soaking ancients, with their turtle faces and their wrinkled hairy bodies.

      After that warm wet hour they dressed, and trooped into the kitchen, damp and pink-skinned, queuing up and filling their plates, sitting at the long tables scattered among the adults. There were one hundred and twenty-four permanent residents, but usually about two hundred people there at any given time. When everyone was seated they took up the water pitchers and poured each other’s water, and then they tore into the hot food with gusto, downing potatoes, tortillas, pasta, tabouli, bread, a hundred kinds of vegetables, occasionally fish or chicken. After the meal the adults would talk about crops or their Rickover, an old integral fast reactor they were very fond of, or about Earth—while the kids cleaned up and then played music for an hour and then games, as everyone began the slow process of falling asleep.

      One day before dinner a group of twenty-two people arrived from around the polar cap. Their little dome had lost its ecosystem to what Hiroko called spiralling СКАЧАТЬ
