Theories of Flight

He waited all of half a second for a reply before seizing the trolley in his free hand and trying to tip it over. Some of the transformers were big ferrite ones, and he couldn’t manage it one-handed. McNeil and the man— Petrovitch’s mind was too full to remember his name—looked at each other.

“You,” he said to the man, “catch.”

He threw the sphere and, without waiting to see if it had a safe arrival, wedged his foot under one of the trolley’s castors and heaved. The contents slid and fell, collecting in a blocky heap on the fifties lino.

He righted the trolley and looked around for what he needed. “Power supply there,” he pointed, and McNeil scurried to get it. “That bundle of leads there. Multimeter, any, doesn’t matter. And the Mukhanov book.”

The other student was frozen in place, holding the sphere like it was made of crystal. Hugo Dominguez, that was it. Had problems pronouncing his sibilants.

“You all right with that?”

Dominguez nodded dumbly.

The quantum gravity textbook was the last thing slapped on the trolley, and Petrovitch took the handle again.

“Right. Follow me.”

McNeil trotted by his side. “Doctor Petrovitch,” she said.

And that was almost as strange as being married. Doctor. What else could the university have done, but confer him with the title as soon as was practically possible?

“Yeah?”

“Where are we going?”

“Basement. And pray to whatever god you believe in that we’re not over a tube line.”

“Can I ask why?”

“Sure.” They’d reached the lift. He leaned over the trolley and punched the button to go down.

“Okay,” she said, twisting a strand of hair around her finger. “Why?”

“Because what I was doing before wasn’t working. This will.” The lift pinged and the door slid aside. Petrovitch took a good long look at the empty space before gritting his teeth and launching the trolley inside. He ushered the two students in, then after another moment’s hesitation on the threshold, he stepped in.

He reached behind him and thumbed the stud marked B for basement.

As the lift descended, they waited for him to continue. “What’s the mass of the Earth?” he said. When neither replied, he rolled his eyes. “Six times ten to the twenty-four kilos. All that mass produces a pathetic nine point eight one meters per second squared acceleration at the surface. An upright ape like me can outpull the entire planet just by getting out of a chair.”

“Which is why you had us build the mass balance,” she said.

“Yeah. You’re going to have to take it apart and bring it down here.” The door slid back to reveal a long corridor with dim overhead lighting. “Not here here. This is just to show that it works. We’ll get another lab set up. Find a kettle. Stuff like that.”

He pushed the trolley out before the lift was summoned to a higher floor.

“Doctor,” said Dominguez, finally finding his voice, “that still does not explain why we are now underground.”

“Doesn’t it?” Petrovitch blinked. “I guess not. Find a socket for the power supply while I wire up the rest of it.” He took the sphere from Dominguez and turned it around until he found the two holes. His hand chased out a couple of leads from the bird’s nest of wires, spilling some of them to the floor. The lift disappeared upstairs, making a grinding noise as it went.

They worked together. McNeil joined cables together until she’d made two half-meter lengths. Dominguez set up the multimeter and twisted the dial to read current. Petrovitch plugged two jacks into the sphere, and finally placed Mukhanov and Winitzki’s tome on the floor. He set the sphere on top of it.

“Either of you two worked it out yet?” he asked. “No? Don’t worry: I’m supposed to be a genius, and it took me a week. Hugo, dial up four point eight volts. Watch the current. If it looks like it’s going to melt something, turn it off.”

The student had barely put his hand on the control when the lift returned. A dozen people spilled out, all talking at once.

“Yobany stos!” He glared out over the top of his glasses. “I’m trying to conduct an epoch-making experiment which will turn this place into a shrine for future generations. So shut the huy up.”

One of the crowd held up his camera phone, and Petrovitch thought that wasn’t such a bad idea.

“You. Yes, you. Come here. I don’t bite. Much. Stand there.” He propelled the young man front and center. “Is it recording? Good.”

All the time, more people were arriving, but it didn’t matter. The time was now.

“Yeah, okay. Hugo? Hit it.”

Nothing happened.

“You are hitting it, right?”

“Yes, Doctor Petrovitch.”

“Then why isn’t the little red light on?” He sat back on his heels. “Chyort. There’s no yebani power in the ring main.”

There was an audible groan.

Petrovitch looked up again at all the expectant faces. “Unless someone wants to stick their fingers in a light socket, I suggest you go and find a very long extension lead.”

Some figures at the back raced away, their feet slapping against the concrete stairs. When they came back, it wasn’t with an extension lead proper, but one they’d cobbled together out of the cable from several janitorial devices and gaffer tape. The bare ends of the wire were live, and it was passed over the heads of the watching masses gingerly.

It took a few moments more to desleeve the plug from the boxy power supply and connect everything together. The little red light glimmered on.

Petrovitch looked up at the cameraman. “Take two?”

“We’re on.”

Petrovitch got down on his hands and knees, and took one last look at the inert black sphere chased with silver lines. In a moment, it would be transformed, and with it, the world. No longer a thing of beauty, it would become just another tool.

“Hugo?” He was aware of McNeil crouched beside him. She was holding her breath, just like he was.

Dominguez flicked the on switch and slowly turned the dial. The digital figures on the multimeter started to flicker.

Then, without fuss, without sound, the sphere leaped off the book and into the air. It fell back a little, rose, fell, rose, fell, each subsequent oscillation smaller than the previous one until it was still again: only it was resting at shin-height with no visible means of support.

Someone started clapping. Another joined in, and another, until the sound of applause echoed, magnified, off the walls.

His heart was racing again, the tiny turbine in his chest having tasted the amount of adrenaline flooding into his blood. He felt dizzy, euphoric, ecstatic even. Here was science elevated to a religious experience. Dominguez was transfixed, motionless like his supervisor. It was McNeil who was the first of the three to move. She reached forward and tapped the floating sphere with her fingernail. It slipped sideways, pulling the cables with it until it lost momentum and stopped. She waved her hand under it, over it.

She turned to Petrovitch and grinned. He staggered to his feet and faced the crowd. “Da! Da! Da!” He punched the air each time, and found he couldn’t stop. Soon he had all of them, young and old, men and women, fists in the air, chanting “Da!” at the tops of their voices.

He reached over and hauled Dominguez up. He held his other hand out to McNeil, who crawled up his arm and clung on to him in a desperate embrace. Thus encumbered, he turned to the camera phone and extended his middle finger—not his exactly, but he was at least its owner. “Yob materi vashi, Stanford.”
