Phyfe has a new scrap of metal with inscriptions, and they've found something that almost looks as if it might have been an electron tube five hundred thousand years ago.
In a discussion of how the tunnel diode works, one of the scientists pointed out that if an electron could be brought to absolute rest, its position according to Heisenberg Uncertainty would be completely ambiguous.
Between narrow limits, the voltage bias is correct to upset the ambiguity of Mr. Heisenberg, making the electron nominally found on one side of the junction more likely to be found on the other.
Let us see about this latest theory--the Corpuscle or Electron Theory.
So far the Corpuscles are known only as charged with Electricity, and the Electron only as a tiny charge of Electricity with which the Corpuscle is charged.
Electric waves are produced wherever electrons are accelerated or retarded, that is, whenever the velocity of an electron is changed or accelerated positively or negatively.
Each electron is a point-charge of negative electricity equal to 3.
The size of the electron is to that of an atom roughly in the ratio of a pin's head to the dome of St Paul's cathedral.
The electron is always associated with the unit charge of negative electricity, and it has been suggested that its inertia is wholly electrical.
When a current passes from an electrolyte to a metal, the electron must be detached from the atom it was accompanying and chemical action be manifested at the electrode.
He asserts that: "The electron isolated presents itself as electricity of the negative kind; and in combination with co-electrons and other electrons it forms the atoms of ponderable matter.
He also considers it as a refined matter and the electron as the atom of electricity, in the "Popular Science Monthly" of June, 1903.
As it is, we have to use an electron microscope to see the larger molecules; the wave length of visible light is too coarse-grained to show anything that small.
Phil peering into the electron microscope, and the warm sun lay across Katherine's lap.
Sounds pretty convincing to me," Phil said, and went back to the electron microscope.
The chlorine atoms move away independently accompanied by an extra satellite or electron, and the sodium atoms move away also but with their electron strength one below par.
There is an electronbeam that writes to the surface of the screen, the phosphor coated one.
So, the phosphor coating gets hit with a strong electron beam, full of high voltage energy, and the phosphor glows, just for a few milliseconds.
Lorentz so as to take account of the atomic structure of electricity, are fundamental in modern electrodynamics and the electron theory of matter.
The electron at rest gives rise to the phenomena of electrostatics; in motion, it gives rise to electrical currents, electromagnetism and electric radiation.
Efforts are being made to apply the electronic theory to the various phenomena of electrostatics, the electron being the smallest particle of electricity that can have separate, individual existence.
When radiation interacts with atoms, energy is deposited resulting in ionization (electron excitation).
This action is very slight; moreover, it changes sign in the current of the period; nevertheless, the mean action is not null if there is a difference of phase between the vibrations of the electron and those of the ether.
An electron in motion is analogous to a convection current; therefore every magnetic field, in particular that due to the luminous perturbation itself, must exert a mechanical action upon this electron.
And then it is natural to think that this difference is explained by the positive electron having, besides its fictitious mass, a considerable real mass; which takes us back to the first hypothesis.
Each electron is more sensitive to the field created by the electrons of contrary name than to the field created by the electrons of the same name.
The perturbation is propagated with a finite velocity; it, therefore, reaches the second electron only when the first has long ago entered upon its rest.
In fact, if it absorbs energy, this is because the vibration of the ether impels the electron; the electron must therefore be slower than the ether.
But we may just as well suppose that the real mass is null for these as for the others, but that the fictitious mass of the positive electron is much the greater since this electron is much the smaller.
Just so, if for any cause an electron be put in motion, it would trouble the ether around it and would give rise to luminous waves, and this would explain the emission of light by incandescent bodies.
Looking forward to a time when man will be able to measure even smaller things than the electron and larger than the greatest star system, Prof.
Shapley said, occupies a very small place in all this system, although, beside an electron or an atom, he is not so negligible, at that.
The calculation of this emission from the standpoint of the electron theory alone is a very complex problem which takes us deeply into the structure of matter and which has probably not yet been satisfactorily resolved.
Footnote 115: This fact is so important and at the same time so surprising to the layman, that a quotation from The Electron Theory of Matter by O.
On the kinetic theory, temperature is a measure of the violence of the motion of the ultimate particles; and we have seen that on the electron theory, electromagnetic radiation is a consequence of their acceleration.
It gives a sketch of modern conceptions of the composition of matter, the electron theory, and the recent experimental work on the magnitude of molecules and electrons.
But natural matter does have a tendency to let the electron fall into the proton.
It is true that in mass or weight the electron is a thousand times smaller than the hydrogen atom, yet at the same time it may be conceived that the limits of space which the electron occupies are indefinitely large.
Here we have, then, material for the generation of the electrical current, if some means could be found to induce the chlorine atom to give up the surplus electronwhich from time to time it carries.
The modern theorist goes one step farther, and explains the negative properties of the chlorine atom by assuming the presence of one negative electronor electricity in excess of the neutralizing charge.
We can visualize the ultimate constituent of electricity as an electron one thousand times smaller than the hydrogen atom, which has mass and inertia, and which possesses powers of attraction and repulsion.
Yet it should be understood that the hypothesis of the magnetic electron as the basis of matter, has received an amount of experimental support that has raised it at least to the level of a working theory.
The assumption is, that the sodium atom has lost this negative electron and thus has become positively electrified.
In thus escaping an electron takes away its charge of negative electricity, and the previously neutral atom becomes positively electrified.
Meanwhile the free electron may hurtle about with its charge of negative electricity, or may combine with some neutral atom and thus give to that neutral atom a negative charge.
To an individual particle the name electron was given; and the interesting fact developed that the mass of an electron is only about one-thousandth that of an atom of hydrogen.
To continue the example, the electron may be something much more complex than either a wave or a particle, since it behaves at times like either or both.
From this distance, though, even with an electron telescope, Calhoun could see no movement of any sort.
He'd watched the ground through the electron telescope and he had a mental picture of the city from the sky.
Thomson conceives of a free electron as dashing about from one atom to another at a speed so great as to change its location forty million times a second.
The disproportion between the size of an atom and the size of an electronis vastly greater than that between the sun and the earth.
In the electron we have matter dematerialized; the electron is not a material particle.
The Theory of Ionization and the Electron Theory of Electricity and of Matter.
We may imagine such a double [p065] charge to be produced by the movement of one electron of the nitrogen atom to a position in that atom which would make one point of the atom negative and the other positive.
The loss of one electron by an atom leaves a ‹unit positive charge› on the particle.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "electron" in a variety of sentences. We hope that you will now be able to make sentences using this word.
