gasped Morton, the chemist, as they reached safety. "It's exorthermic—but it formed there!"
IN that instant, Kendall grasped the meaning of the choking fumes carried. "Molecular uncertainty!" he decided. "We're going back—we're getting there—"
He altered the apparatus again, added another atostor in series, reduced the size of his sphere of forces—of strange chaos of uncertainty. Within—little was certain. Without—the laws of nature applied as ever.
Again the apparatus was started, cautiously this time. Only a strange jumbled ionization appeared this time, then a slow, rising blue flame began to creep up, and burn hot and blue. Buck looked at it for a moment, then his face grew tense and thoughtful. "Devin—give me a half-dollar." Blankly, Devin reached in his pocket, and handed over the metal disc. Cautiously Buck Kendall tossed it toward the sphere of force. Instantly there was a flash of flame, soundless and soft-colored. Then the silver disc was outlined in light, and swiftly, inevitably crumbling into dust so fine only a blue haze appeared. In less than two seconds, the metal was gone. Only the dense blue fog remained. Then this began to go, and the leaping blue flame grew taller, and stronger.
"We're on the track—I'm going to stop here, and calculate. Bring the data—"
Kendall shut off the machine, and went to the calculation room. Swiftly he selected already prepared graphs, graphs of the math, he had worked on. Devin came soon, and others. They assembled the data and with tables and arithmetical machines turned it into graphs.
Then all these graphs were fed into the machine. There were curves, and sine-curves, abrupt breaking lines—but the answer that came but when all were compounded was a perfect diagram of a flight of four steps, decending in unequal treads to zero.
Kendall looked at it for long minutes. "That," he said at length, "is what I expected. There are four degrees of uncertainty, we generated 'Uncertainty of the First Degree,' 'Mass Uncertainty' when we started. That, as here shown, takes little energy concentration. Then we increased the energy concentration and got 'Uncertainty of the Second Degree,' 'Molecular Uncertainty.' Then I added more power, and reduced the field, and got 'Uncertainty of the Third Degree'—'Atomic Uncertainty.' There is 'Uncertainty of the Fourth Degree' It is barely attainable with our atostors. It is—utter uncertainty."
"In the First Degree, the laws of mass action fail, the great broad-reaching laws. In the Second Degree, the laws of the molecules, a finer organization, break down, and anything can happen in chemistry. In the Third Degree, the laws of atomic physics break down slowly. The atom is tough. It is very compact, and we just barely attained the concentration needed with that apparatus. But—in the Third Degree, when the Atomic Laws break down into utter uncertainty, the atoms break, and only hydrogen can exist. That was the blue flame."
"But the Fourth Degree—there is no law whatsoever, nothing in all the Universe can exist. It means—the utter destruction and release of the energy of matter!" Kendall paused for a moment. "We have won, with this. We need only make up this apparatus—and maybe make it into a
