Tilting the Balance

None of your business, Nazi, she thought. With the first smile of genuine amusement she’d worn since she flipped her aircraft, she said, “Shall we be off, comrades?” The rest of the trek back to the airstrip was liable to be interesting.

Along with the rest of the physicists, Jens Larssen watched tensely as Enrico Fermi manipulated the levers that raised the cadmium control rods from the heart of the rebuilt atomic pile under the University of Denver football stadium.

“If we have the design correct, this time the k-factor will be greater than one,” Fermi said quietly. “We will have our self-sustaining chain reaction.”

Beside him, Leslie Groves grunted. “We should have reached this point months ago. We would have, if the damned Lizards hadn’t come.”

“This is true, General,” Fermi said, though Groves still wore colonel’s eagles. “But from now on work will be much faster, partly because of the radioactives we have stolen from the Lizards and partly because they have shown us that what we seek is possible.”

Larssen thought about Prometheus stealing fire from the gods and bringing it down to mankind. He thought about what happened to Prometheus afterwards too: chained to a rock somewhere, with an eagle gnawing his liver forever. He suspected a lot of his colleagues had had that image at one time or another.

Unlike most of them, of course, he didn’t need the Met Lab to have a feel for the myth of Prometheus. Every time he saw Barbara hand in hand with that Sam Yeager, the eagle took another peck at his liver.

The project was an anodyne of sorts, though the pain never left him, not entirely. He watched the instruments, listened to the growing chatter and then the steady roar of the Geiger counter as it let the world know about the growing cloud of neutrons down in the heart of the pile. “Any second now,” he breathed, more than half to himself.

Fermi drew out the rods another couple of centimeters. He too glanced at the dials, worked his slide rule, scrawled a quick calculation on a scrap of paper. “Gentlemen, I make the k-factor here to be 1.0005. This pile produces more free. neutrons than it consumes.”

A few of, the physicists clapped their hands. More just nodded soberly. This was what the numbers predicted. All the same, it remained a solemn moment. Arthur Compton said, “The Italian navigator has discovered the New World.”

“Gentlemen, this means you can now produce the explosive metal we need to make bombs like the ones the Lizards use?” Groves said.

“It means we are a long step closer,” Fermi said. With that, he lowered the control rods back into the pile. Needles swung to the left on the instrument board beside him; the rhythm of the Geiger counter’s clicks slowed. Fermi let out a small sigh of relief. “And, it seems, we can control the intensity of the reaction. This is also of some considerable importance.”

Most of the scientists smiled; Leo Szilard laughed out loud. Larssen had the urge to yank the cadmium rods all the way out of the pile and leave them out until the uranium spat radiation all over, the stadium, all over the university, all over Denver. He fought it down, as he had other lethal, but less spectacular, impulses over the past weeks.

“What do we do next?” Groves demanded. “What exactly do we have to accomplish to turn what we’ve got here into a bomb?” The big man was not a nuclear physicist, but he had more determination than any four Nobel Prize winners Jens could think of. If anybody could drive the project to, success by sheer force of will, Groves was probably the one.

Leo Szilard, on the other hand, had his own sort of practicality. “There is in my office a bottle of good whiskey,” he remarked. “What we do next, I say, is to have a drink.”

The motion passed by acclamation. Jens trooped over to the science building with everyone else. It was good whiskey; it filled his mouth with the taste of smoke and left a smooth, warm trail down to his stomach. The only thing it couldn’t do was make him feel good, which was why people had started distilling whiskey in the first place.

Szilard raised the bottle. A couple of fingers’ worth, coppery bright like a new penny, still sloshed there. Jens held out his glass (actually, a hundred-milliliter Erlenmeyer flask he devoutly hoped had never held anything radioactive) for a refill.

“You have earned it,” Szilard said, pouring. “All that work on the pile-”

Jens knocked back the second shot. It hit hard, reminding him he hadn’t had any lunch. It also reminded him he didn’t have any business celebrating; no matter how well his work was doing, his life was strictly from nowhere.

“Good booze,” said one of the engineers who’d worked under him. “Now we all oughtta go out and get laid.”
