A Quote by Johannes Stark
We have learnt through experience that when an electrical ray strikes the surface of an atom, an electron, and in some circumstances a second and even a third electron, can be detached.

The removal of an electron from the surface of an atom - that is, the ionization of the atom - means a fundamental structural change in its surface layer.
In size the electron bears the same relation to an atom that a baseball bears to the earth. Or, as Sir Oliver Lodge puts it, if a hydrogen atom were magnified to the size of a church, an electron would be a speck of dust in that church.
Crystallographers believed in X-ray results, which are of course very accurate. But the x-rays are limited, and electron microscopy filled the gap, and so the discovery of quasicrystals could have been discovered only by electron microscopy, and the community of crystallographers, for several years, was not willing to listen.
There was a time when we wanted to be told what an electron is. The question was never answered. No familiar conceptions can be woven around the electron; it belongs to the waiting list.
The rigid electron is in my view a monster in relation to Maxwell's equations, whose innermost harmony is the principle of relativity... the rigid electron is no working hypothesis, but a working hindrance. Approaching Maxwell's equations with the concept of the rigid electron seems to me the same thing as going to a concert with your ears stopped up with cotton wool. We must admire the courage and the power of the school of the rigid electron which leaps across the widest mathematical hurdles with fabulous hypotheses, with the hope to land safely over there on experimental-physical ground.
Can a physicist visualize an electron? The electron is materially inconceivable and yet, it is so perfectly known through its effects that we use it to illuminate our cities, guide our airlines through the night skies and take the most accurate measurements. What strange rationale makes some physicists accept the inconceivable electrons as real while refusing to accept the reality of a Designer on the ground that they cannot conceive Him?
The electron is first of all your concept of the electron.
The magnetic cleavage of the spectral lines is dependent on the size of the charge of the electron, or, more accurately, on the ratio between the mass and the charge of the electron.
An electron is an electron, but you can decide where to send your electric-bill payment. You can't redirect the electrons, but you can your dollars. The dollars will drive generation choices.
The electron, as it leaves the atom, crystallises out of Schrodinger's mist like a genie emerging from his bottle.
The laws of science, as we know them at present, contain many fundamental numbers, like the size of the electric charge of the electron and the ratio of the masses of the proton and the electron .... The remarkable fact is that the values of these numbers seem to have been finely adjusted to make possible the development of life.
According to well-known electrodynamic laws, an electron moving in a magnetic field is acted upon by a force which runs perpendicular to the direction of motion of the electron and to the direction of the magnetic field, and whose magnitude is easily determined.
But it is necessary to insist more strongly than usual that what I am putting before you is a model-the Bohr model atom-because later I shall take you to a profounder level of representation in which the electron instead of being confined to a particular locality is distributed in a sort of probability haze all over the atom.
When I was 16 years old, I assembled a 2.3 million electron volt beta particle accelerator. I went to Westinghouse, I got 400 pounds of translator steel, 22 miles of copper wire, and I assembled a 6-kilowatt, 2.3 million electron accelerator in the garage.
I always imagined myself somehow as an electron around some atom, and you're just, like, bouncing around and spinning. There was a never-ending supply of places to go, people to see, things to do, and fitting it all in became kind of an art.
It would be great if you could cool the water and immobilise the molecules, though keeping the structure, because when it's frozen, when it's immobilised, you can have it in the electron microscope and the water will not evaporate because in the electron microscope, it must be under vacuum, and water at normal temperature evaporates.
