If other electrons follow the first within a wire, their passage along the wire will be what is called an electric current. Cf. Sir Oliver Lodge, Electrons, London, 1906, p. 200. When the electron is subjected to an acceleration, a transverse wave is produced, and an electromagnetic radiation is generated, of which the character may naturally change with the manner in which the speed varies.
Then the electron telescope revealed a stubby, rotund cargo-ship, about to land on Mekin. Bors swore. It would be days before this tub reached Mekin on solar-system drive. But it must not report that an armed vessel had inspected it in remoteness. "We haul alongside," said Bors angrily. "Boarding-parties ready in the space-boats."
The Med Ship was only planetary diameters from Orede, now, and the electron telescope showed shining stars in leisurely motion across its screen. Then a huge, gibbous shining shape appeared, and there were irregular patches of that muddy color which is seabottom, and varicolored areas which were plains and forests. Also there were mountains. Calhoun steadied the image, and squinted at it.
An atom will repel an atom when its equilibrium is disturbed by the approach of an additional electron; the physicist even follows the movement of the added electron, and describes it revolving 2200 billion times a second round the atom, to escape being absorbed in it. The difference between good and bad conductors of electricity becomes intelligible.
Most of the weight was on the outside; a dazzlingly bright plating of collapsium collapsed matter, the electron shell collapsed onto the nucleus and the atoms in actual physical contact and absolutely nothing but nothing could get through it.
That the instrument used to measure the position of the electron must inevitably move the electron; and the greater the attempt at precise measurements, the greater the error produced by the measurements. "It was my hope," he went on, "to provide greater accuracy of measurement, by use of statistics over the vast number of electrons in orbit around the hydrogen atoms within the test mass.
They are present in a free condition in metallic conductors. Each electron carries an electric charge of electrostatic units and produces a magnetic field in a plane perpendicular to the direction of its motion.
He wrote many papers on geometrical optics and on molecular physics, but his great claim to remembrance is that he first suggested, "on the basis of Faraday's law of Electrolysis, that an absolute unit of quantity of electricity exists in that amount of it which attends each chemical bond or valency and gave the name, now generally adopted, of electron to this small quantity."
Now before leaving the atom please note that it is as much smaller than the diagram as the latter is smaller than our solar system. What Is Meant by Ionization. A hydrogen atom is not only lighter but it is smaller than the atom of any other element while an electron is more than a thousand times smaller than the atom of which it is a part.
Each proton and electron fitted itself more snugly against the north pole face and pushed with the entire force of its newly-imposed inertial pattern. Forty pounds to the square inch six hundred forty pounds over the surface of the block, the plastic did its best to assume the motion that the warped laws of its existence said that it already had.
