"Tom Maddox - Gravity's Angel" - читать интересную книгу автора (Maddox Tom)тАЬTell me what this is all about,тАЭ I said. тАЬSo IтАЩll know what weтАЩre looking at when this stuff runs.тАЭ тАЬSure,тАЭ she said. While we waited for QUARKER, she drew equations and plots on my whiteboard in red, green, black, and yellow, and she explained that she was postulating the existence of a new kind of attractor that came into being in a region of maximum chaos, its physical result an impossible region of spacetime, where an infinite number of particle events occupied a single, infinitesimal point. Mathematically and otherwise, it is called a singularity, and in cosmology something like it is assumed to be at the center of black holes. There were all sorts of theorems about singularities, few of which I knew, none rigorously. Why would I? This stuff went with astrophysics and the gravitational forces associated with huge chunks of mass. When she finished her explanations and turned from the whiteboard, I could see that she was wired and sleepy at once. Mostly, though, she was exultant: she felt sheтАЩd hit the jackpot. And of course she had, if any of this made sense ... it couldnтАЩt, I thought. The Thing gonged, to tell us we had our results. I pulled up a canvas-backed chair beside her as she sat at the console. тАЬWeтАЩll walk through the simulation,тАЭ she At first there were just cartoon schematics of the detectors; line drawings of the big central detector and its surrounding EM boxes, hadron calorime-ters, and gas chambers. Then the beam shots started coming, and in a small window at the top of the screen, the beam parameters reeled by. Running Monte Carlos is one hell of a lot easier than doing an actual run; you donтАЩt have the actual experimental uncertainties about good beam, good vacuum, reliable detector equipment; itтАЩs a simulation, so everything works right. As we watched, the usual sorts of events occurred, particles and antiparticles playing their spear-carrying roles in this drama, banging together and sending out jets of energy that QUARKER dutifully calculated, watching the energy-conservation books the whole time, ready to signal when something happened it couldnтАЩt fit into the ledger. Complex and interesting enough in its own way, all this, but just background. QUARKER shifted gears all of a sudden, signaling it had so many collisions it could not track them accurately. The screen turned into what we called a тАЬhedgehog,тАЭ a bristly pattern of interactions too thick to count. тАЬWe donтАЩt care,тАЭ Carol Hendrix whispered. тАЬDo it.тАЭ And she forced QUARKER to plunge ahead, made it speed up the pictures of events. She didnтАЩt care about the meanings of the individual events; she was looking for something global and, I thought, damned unlikely. |
