But as the very slightest expenditure of energy is sufficient to produce the commencement of electrolysis, it is necessary to suppose that these two ions are not united by any force. Thus the two ions are, in a way, dissociated.
THE HE-ANCIENT. It imprisons us on this petty planet and forbids us to range through the stars. ACIS. But even a vortex is a vortex in something. You cant have a whirlpool without water; and you cant have a vortex without gas, or molecules or atoms or ions or electrons or something, not nothing.
We are thus dealing with rather large ions, but according to Mr Wilson, this condensation phenomenon does not affect the number of ions produced by dissociation. In proportion as the temperature rises, the molecules condensed round the nucleus disappear, and, as in all other circumstances, the negative ion tends to become an electron, while the positive ion continues the size of an atom.
Here in the lower air, where ions would be so plentiful, Thett did not try to break down the screens, for the air would aid the defenders. Finally, as Thett's forces had planned, they came to one of the ionized layer ray-screen stations that was still projecting its cone of protective screening to the layer above.
Here Arrhenius comes once more with his hypothesis of negative corpuscles, or ions, driven away from the sun by light-pressure a hypothesis which seems to explain so many things and offers it also as an explanation of the way in which the sun creates the Aurora. He would give the Aurora the same lineage with the Zodiacal Light.
I think I can explain it best by a simile I use with my classes. It is as though you had a ballroom in which the dancers in couples represent the neutral molecules. There are a certain number of isolated ladies and gentlemen dissociated ions " "Who don't know these new dances?" I interrupted. "They all know this dance," he laughed.
In certain kinds of scientific argument any attempt at persuasion as such would be an impertinence: whether heat is a mode of motion, whether there are such infinitesimal bodies as the ions which physicists of to-day assume to explain certain new phenomena, whether matter consists of infinitesimal whirls of force in all such questions an argument appeals solely to the reason; and in such Bacon's favorite apophthegm has full sway, Dry light is ever the best.
A few moments later he withdrew the positive electrode. Both it and the meat under it were blue! "What has happened?" he asked. "The iodine ions have actually passed through the beef to the positive pole and the paper on the electrode. Here we have starch iodide." It was a startling idea, this of the introduction of a substance by electrolysis.
The beam was evidently swung at random intervals, and the phenomenon lasted for an hour and a half. Anyone but Lockley behind a cloud of ions would have been reduced to shivering hysteria. Then, suddenly, the beamings stopped. But Lockley left his device in operation.
It's scattered until it simply doesn't penetrate!" Lockley suddenly seemed indignant at his own failure to see something that had been so obvious all along. "If we could make a cloud of ions, it should stop the terror beam as clouds stop light! We could " Again he stopped short, and Jill's expression changed. She looked confident again.
