The Machine That Floats by Joe Gibson (bill gates books recommendations .txt) 📕

was the closest Einstein could come to explaining that!

Still, a word could be invented for it, Morrow supposed. Not that he understood what the new word was supposed to define—but then, had Edison known what electricity was? No! He had merely experimented and learned what it would do, and then designed mechanisms which would utilize it.

Morrow didn't know what "gravity and magnetic moment" was, either—nor "angular momentum"—but he had discovered what it would do. It, not they—it was all the same thing. And he designed a mechanism. And the mechanism worked.

It defied "gravity."

With its volume turned up, it could very probably lift him to any height above the Earth he desired, with its ability growing weaker only as it rose out of the Earth's gravity and magnetic field. And it would keep him suspended, if he desired, until its batteries burned out.

There would be limitations, of course. Perhaps the Earth's gravity and magnetic fields would be too weak at, say, an altitude of fifty miles for the mechanism to function. There were probably limits to the mass and weight it could lift. There would have to be extensive tests—

And a cellar workshop was no place to conduct them!

He straightened up from the workbench and moved forward on the balls of his feet. He spread his arms wide as he approached the mechanism, like a basketball player approaching a wary opponent who had the ball. Smoke from the cigarette dangling out of the corner of his mouth streamed up and stung his eye. He wished he had left it back on the workbench.

At first, the little mechanism ignored him. Then, almost instinctively, it seemed to notice him. It went sliding away from him, toward the wall.

Morrow moved forward, cautiously.

It glided close to the wall, then rebounded gently. It came drifting back toward him—then hesitated, started off in a tangent—and he grabbed for it. A faint, tingling shock went up his arm as he clawed at the shiny metal loops, but that was all. He hung on grimly as it tugged at his fingertips; then, as its influence swept through him and attuned his body to it, it snuggled up to him, suddenly friendly.

He snapped it off and felt its inert weight settle down familiarly in his hands. He carried it back to the workbench, set it down, and threw a rag over it.

Then he pulled off his coveralls, went upstairs to the kitchenette, and washed his hands.

There were other factors to consider, of course. Especially the ones he didn't want to think about—the frightening ones—

He stared down at his hands, feeling the cool water run pleasantly over them. Strong, supple hands. Well-proportioned, muscular. A little bit like the rest of him. Not fat or skinny, not soft-muscled nor, again, as bulgingly muscular as a wrestler. Just firm flesh, strong and not too much of it, on a strong-boned skeleton frame. Nerves well-coordinated, reflexes good. But tired. Mentally fatigued, the psycho-therapists said, from living in a world of raw tensions. According to them, ninety percent of the American public suffered mental fatigue. There had been a slew of magazine articles and several books about it.

The Cold War, the war that wasn't a war. The Russkies.

Morrow turned off the cold-water tap and glanced at his image in the shaving mirror. A slender face, a good nose, a firm mouth with slightly too much jaw. Dark hair tumbled in comfortable looseness over a lined forehead. Gray eyes that mocked him as he mocked himself.

He dried his hands and got a couple of cans of beer out of the refrigerator. Grabbing a can-opener and a glass, he strolled in through the small, dark bedroom to the front living room and sprawled himself out in the deep chair beside the television set. It was a small home, a comfortable home, and he enjoyed prowling around in it in his socks, loafers, and shorts. He scratched his left leg and opened a can of beer.

He was, Morrow concluded, the product of an age of terror. East was Russia and west was the Allied Nations, and in between was a veritable No Man's Land. Radar blanketed the skies, rocket missiles stood on their firing-racks, long-range bombers waited to deliver atomic death and swift jet-fighters waited to do battle with them. The diplomats called it a balance of power; the military strategists, a balance of forces, wherein neither side could launch an atomic war without suffering complete annihilation by the other.

And so, said the statesmen, there would be no atomic war.

The only trouble was, they couldn't convince the people. Too many self-minded individuals saw the world situation as two sticks of dynamite rubbing against each other. At any moment, both might explode. Massive war industry and compulsory military training for their youngsters didn't make the public feel any more secure.

Nor, of course, did the generals want them to feel secure. The Allied generals moved their armies in threatening maneuvers near critical borders to increase the fear of the peoples in communist-dominated countries; the Russian generals did likewise to increase the fear of people in the Allied Nations. And the diplomats hurled threats back and forth in the United Nations' assemblies to achieve the same purpose.

Militarily, the two sides had reached a stalemate. The final weapon was the people. Each side hoped the people of the other side would rise up in revolt, thus breaking the deadlock and winning the struggle, but humanity is notoriously stubborn. It was, nonetheless, rather hard on the people.

Individual lives were deeply affected, sometimes for better and sometimes for worse.

Morrow's life had, so far, been for the better. In high school, certain aptitude tests had placed him in advance physics classes; upon graduation, at seventeen, he had spent a year in a government-sponsored engineering school. At eighteen, further tests had placed him in the Air Force, assigned as radar-operator to the rear cockpit of a sleek, all-weather jet-fighter. He spent two years patrolling the stratosphere over the vast, white expanse of the Arctic Ocean. At twenty, he was reassigned to engineering school and spent four years studying electronics, during which time he was returned to civilian status. He was placed at Western Electronics as a production engineer; by the time he was twenty-seven, he had worked his way up to the Research Division. His flying experience helped considerably, but it wasn't all. He was deeply in love with electronics. He had studied Einstein's equations, for example, and got something out of them that most of the others missed. No one knew exactly what it was—neither did Morrow—but he began to have "hunches" that often paid off.

In electronics, that was a priceless faculty. A great deal of it, especially in the research department, was still pretty much of a hit-or-miss affair. There still wasn't a man who knew exactly what electricity was!

Now, at twenty-nine, he had gotten another of those "hunches." It worked, too! The machine floated!

He gazed thoughtfully out the broad picture window at the stretch of green lawn, the sidewalks, the trees along the street and the other little prefab houses of his neighbors. The evening shadows were cool and deepening as night approached. Warm, yellow light poured from the windows across the street.

He was comfortable here in his little, company-owned bachelor's home. Most of the town of Westerton was owned by Western Electronics, with its huge, sprawling plant buildings on the other side of the small valley, across the railroad tracks. Like most of the bachelor engineers, he ate most of his meals over at the company cafeteria. A cleaning-woman came twice a week to tidy up his little house, though he was a fairly conscientious housekeeper himself.

And like practically all the engineers, he had a small workshop patched together in his cellar, built from odds and ends salvaged from the company's junk-pile of rejected parts, a few pieces scrounged from the laboratories, and some odd bits made in the machine-shop over the protests of its foreman. There were nine amateur radio-hams sharing the wave-bands in Westerton and vicinity, and no office-clerk's housewife ever had any difficulty getting a recalcitrant dishwasher or electric iron fixed.

It was here, in his private workshop, that he had developed his "hunch" to startling reality. Working in his spare time, figuring out its mathematical components, then working those components into theoretical diagrams, then designing and building the machine to fit the diagrams—and it worked!

Also, it was fantastic. It had been a little too fantastic for him to mention it to any of the others at the labs. His fellow-engineers—some of whom were considerably older than he was—were a little too staid for that. They, too, were products of the age; their entire efforts and, indeed, most of their interests were tied up in the one, basic problem of making better electronic devices for better weapons for the Armed Forces. They couldn't be blamed for that, the world situation being what it was, but it did make them somewhat hide-bound.

The idea of controlling the pull of gravity was a little too fanciful for them, Morrow feared—or if they had any interest in the idea at all, it would be in the possible uses of it as a military weapon. That was the way to get ahead as a scientist, these days!

Morrow shuddered involuntarily.

There was the thing he actually feared!

He drew it into his thoughts, slowly, and analysed it. Item: he had discovered a means of controlling gravity. Item: he had developed a mechanism which worked on that principle. Addenda: the mechanism could lift a human being, quite possibly as much mass as a heavy tank, and it might even open the way to interplanetary travel.

Quite obviously, it had terrific potentialities as a weapon of war.

And it was his patriotic duty, as a citizen of the United States, to turn his
