Spacetime Donuts by Rudy Rucker Page B

Space-Head Show . . . Tuesday mornings at nine. Yeah. Now that I remember that, I can't see the electrons. That's really weird, as soon as you reminded me it got all cloudy . . . what is this?"
    But Vernor had no answer. The electron cloud had now grown to the size of a cathedral. The glowing nucleus was a pearl of light in the center. The atom seemed to be moving towards them. As with the plastic molecule before, he had the strange illusion that the atom's behavior was purposeful, that it was moving towards them because it sensed their presence. Was everything they met going to try to eat them?
    Vernor covered his eyes with his hands to think. How could the atom's appearance depend on what he expected to see? When he put the Uncertainty Principle out of his mind he saw a miniature solar system . . . like now . . . he watched the sixteen electrons circling around the oxygen nucleus. Mick and Vernor were so small now that their time-scale was on a par with that of the atom, so it was easy to watch the electrons as long as you believed in them . . . there was one dropping down to a lower orbit . . . a photon went wriggling away from this event. With a start Vernor realized that his hands were still over his eyes. He opened his mouth, but Mick was already talking.
    "Vernor, I can see with my eyes closed! It's like when I took my first acid trip. I just sense where everything is . . . feel it with my brain!" Without turning his head, Vernor could see that Mick was lying on the floor of the scale-ship with his eyes closed . . . and he could easily hear him yell, "Oh, yes!" to the approaching nucleus.
    Vernor observed the nucleus only superficially and grappled with the problem of how they could be seeing without their eyes. It must be some type of field acting directly on his brain, he reasoned. Conceivably a field could produce mental images . . . the brain's memory storage was basically holographic, so perhaps the interference pattern between his memory field and some external field could produce these slightly hallucinatory images he was observing . . . the nucleus seemed to glow approvingly . . . but what kind of field would it be? The nuclear boson forces could not reach this far, the electromagnetic field was too coarse, so that left gravitation . . . but, no, gravitational effects would be flattened out by the Virtual Field before they could reach him here. Suddenly the answer popped into his mind. "Probability amplitudes!" Vernor shouted. "The pure quantum field!"
    "Man, stop trying to explain it," Mick said quietly. "Get loose while you still can. Look at it."
    It was something to look at all right. The oxygen atom had grown to an immense size, and they were drifting in through the electron cloud. The specificity of their presence was introducing violent turbulence and instability in the atom. One minute they were in a swirling probability fog; the next, electrons were rumbling past them like trucks. Several electrons spiraled down into the nucleus, emitting a variety of smaller particles on the way.
    Their progress through the electron shells was uneven; they proceeded in jumps, and each jump was accompanied by crashes and showers of sparks.
    Suddenly they were through the electrons' domain and the bare nucleus blazed ahead of them, perhaps half the size of the scale-ship. It was growing rapidly as they drifted towards it. A deep rumbling filled their tensegrity sphere, and the smell of sulfur and burnt earth filled their nostrils. Vernor was not surprised . . . if the quantum mechanical probability field could act directly on the memory structure of his brain to produce visual images, there was no reason it couldn't produce the sounds and smells as well. Intellectually he was hardly surprised . . . but on the gut level he was as scared as he'd ever been.
    The nucleus was a dusky red interspersed with patches of black and threads of glowing white. Its shape, although roughly
