Time

And she wondered if that was exactly what she had found here in Africa.

She stepped onto her balcony.

Looking up at the stars, Michael’s stars, she could tell she was far from home. She recognized Ursa Major. But the familiar childhood panhandle shape was upside down, and its pointer stars were pointing below the horizon. And when the Moon rose, it climbed straight up into the sky, heading for a point somewhere over her head. Not only that, it was tipped up sideways; the Man in the Moon’s forehead was pointing north.

But it wasn’t the Moon that was tipped; it was herself. She had flown around the belly of the planet, which was thereby proven to be round. It was a startling thought.

I should travel more, she thought.

How was it possible for a kid on the fringe of the African bush to figure out so much fundamental physics?

If she and Malenfant had had kids, she supposed, she might have a better instinct on how to handle this situation. But they hadn’t, and the whole world of children, damaged or super-intelligent or otherwise, was a mystery to her.

On a whim, she unfolded her softscreen and looked up the properties of gold.

She learned that relativistic effects, the strange and subtle effects of very high speeds and energies, determined the color of gold.

In light elements, electrons orbited the nuclei of atoms at a few hundred miles per second — fast, but only a few percent of the speed of light. But in elements with massive nuclei — like uranium, lead, or gold — the electrons were dragged around at a large fraction of the speed of light, and relativity effects became important.

Most metals had a silvery luster. But not gold. And that was because of the strange high-speed phenomena Michael seemed intuitively to understand: relativity time-dilation effects operating deep within the gold atoms themselves.

She took off her ring and put it on the balcony before her. The stars were reflected in its scuffed surface. She wondered what Michael had seen as he stared into her ring.

When she got back to the States she discovered that Malenfant had found out about the accelerator project clearances and had holed himself up at Fermilab — where Dan Ystebo claimed, almost immediately, to have results.

She flew straight on to Illinois.

New York Times:

From an unpromising grade school in a run-down neighborhood at the heart of New York City has come what may prove to be the most striking example yet of the recent wave of brilliant children ‹background›.

A group of children here — average age just eight — seem to have come up with a proof of the mathematical statement called the Riema

The result has electrified, terrified, astonished, according to temperament. The children at this New York school may the first to attract serious attention from the academic and business communities and the federal government as a potential national resource.

And they have also become the first to require round-the-clock armed guards.

The news of this obscure mathematical result has crystallized the fear some people seem to be forming over these superkids. Police were forced to head off a mob that marched out to the school: angry, scared, evidently with ugly intent, a mob that had even included some of the parents and older brothers and sisters of the children themselves.

Emma Stoney:

Fermilab turned out to be thirty-five miles west of Chicago, close to a town called Batavia. From the air Illinois was a vast emptiness studded by lost-looking little towns. Disoriented, jet-lagged, she glimpsed Fermilab itself, the perfect circle of the collider ring set amid green tallgrass prairie, presumably replanted.

She wasn’t sure what she had expected of a superscience lab like this. Something futuristic, maybe: a city of glass and platinum where steely eyed men in white suits made careful notes on super-advanced softscreens. What she found was an oddly parklike campus littered by giant constructions, like the abandoned toys of some monster child.

This artificial landscape, the huge constructions, made a startling contrast with the bare bleakness of Africa. But the concrete was cracked and streaked with rust and mold. This was an aging, underfunded place, she thought, a lingering dream of a more expansive age.

But here and there she saw the sleek, cool curves of the Teva-tron itself, a three-mile-wide torus within which subatomic particles were accelerated to a substantial fraction of the speed of light.

The main hall was called Wilson Hall, a surreal sixteen-story sculpture of two towers co

“It’s a technocrat’s wet dream.”

“They rebuilt the prairie afterward, you know. They even have a herd of buffalo here.”

“We’re not here for the buffalo, Malenfant. Shall we get this over with?”

He gri

He led her deeper into the complex, and into the cramped and jumbled technical areas. She found herself squirming past gigantic, unrecognizable pieces of apparatus. There were steel racks everywhere, crammed with badly packed electronic instrumentation, and cable bunches over the floor, walls, and ceilings; in some places the cables were bridged by little wooden ladders. There was a smell of oil, shaved metal, cut wood, cleaning solvents, and insulation, all overlaid by a constant, clamoring, metallic noise. There was none of the controlled cool and order she’d expected.

Malenfant brought her to what he called the muon laboratory. This was some way away from the accelerator ring itself; it seemed that beams of high-speed protons were drawn off from the ring and impacted into targets here.

And here they found Dan Ystebo, wearing a smeared white coat over a disreputable T-shirt, hunched over softscreens spread out on a trestle table. The screens were covered with particle-decay images and charts of counts, none of which Emma could understand.

Dan’s broad face split into a grin. “Yo, Emma. Have you

heard?”

“One step at a time,” Malenfant said. “Tell her what you’re

doing here, Dan.”

Dan took a breath. “Making neutrinos. We’re slamming the

Tevatron’s protons into a target to make pions.”

“Pions?”

“A pion is a particle, a combination of a quark and its antiquark, and it is unstable. Pions decay into, among other things, neutrinos. So we have our neutrino source. But it should also be a source of advanced neutrinos, neutrinos coming from the future, arriving in time to make our pions decay.” “Backward ripples,” Emma said.

“Exactly — hopefully modified, and containing some signal.”

“How do you detect a neutrino?”

Malenfant grunted. “It isn’t easy. Neutrinos are useful to us in the first place because matter is all but transparent to them. But we have a full-scale neutrino detector: a ton of dense photographic emulsion, the stuff you use on a camera film. When charged particles travel through this shit they leave a trail, like a jet contrail.”

“I thought neutrinos had no charge.”

“They don’t,” Dan said patiently. “So what you have to look for is a place where tracks come out but none go in. That’s where a Tevatron neutrino has hit some particle in our emulsion. You get it? You have a mass of counters and magnets downstream of the emulsion, and you measure the photons with a twenty-ton lead-glass detector array, and the results are storedon laser discs and analyzed by the data-acquisition software.”
