Words matter. These are the best Electron Quotes from famous people such as Pieter Zeeman, Tom Freston, Bill Callahan, Sam Kean, Dan Shechtman, and they’re great for sharing with your friends.
On the basis of Lorentz’s theory, if we limit ourselves to a single spectral line, it suffices to assume that each atom (or molecule) contains a single moving electron.
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.
You know how on Christmas day, the day feels different, even if you’re just sitting in your chair waiting for your girlfriend to put her face on and you haven’t even started any of the festivities yet, the day still feels different. The electrons are fatter and pushier.
Atoms of Element 118 fill an outer shell with electrons, creating a special type of element called a noble gas. Noble gases are natural turning points on the table, ending one row and pointing to the next.
On April 8, 1982, I was alone in the electron microscope room when I discovered the Icosahedral Phase that opened the field of quasi-periodic crystals.
Atoms consist of a positive nucleus and negative electrons flying around outside it. Electrons closest to the nucleus feel a strong negative-on-positive tug, and the bigger atoms get, the bigger the tug. In really big atoms, electrons whip around at speeds close to the speed of light.
We may say that a basic substance is one which has a lone pair of electrons which may be used to complete the stable group of another atom, and that an acid is one which can employ a lone pair from another molecule in completing the stable group of one of its own atoms.
Nevertheless, all of us who work in quantum physics believe in the reality of a quantum world, and the reality of quantum entities like protons and electrons.
My project was radiation damage of Si and Ge by energetic electrons, critical for the use of the recently developed semiconductor devices for applications in outer space.
The uncertainty relation does not refer to the past; if the velocity of the electron is at first known and the position then exactly measured, the position for times previous to the measurement may be calculated.
We have shown that it is possible to create a radioactivity characterized by the emission of positive or negative electrons in boron and magnesium by bombardment with alpha rays.
In the early 1950s, during the near avalanche of discoveries, rediscoveries, and redefinitions of subcellular components made possible by electron microscopy, those prospecting in this newly opened field were faced with the problem of what to do with their newly acquired wealth.
What the ultrafast laser does is that because it doesn’t have to just cut from the surface, it’s only at the intense focal point that it does this damage where the electrons come off the atoms, you could actually put your laser and scan it over your cornea and it would cut underneath that.
I have never seen a proton or electron spinning around it. I have never actually seen a chromosome. I trust that they exist because people who I trust tell me they do.
If you had to sum up chemistry in one sentence, it might be this: Atoms need to have full shells of electrons to feel satisfied, and different elements steal, shed, or borrow different numbers of electrons to achieve a full shell.
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.
You’d need a very specialized electron microscope to get down to the level to actually see a single strand of DNA.
In the 1920s, a generation before the coming of solid-state electronics, one could look at the circuits and see how the electron stream flowed. Radios had valves, as though electricity were a fluid to be diverted by plumbing. With the click of the knob came a significant hiss and hum, just at the edge of audibility.
We appear to have form, but we are like a whirlpool. We appear to have form, but we are just whirling electrons.
While classical mechanics correctly predicts the behavior of large objects such as tennis balls, to predict the behavior of small objects such as electrons, we must use quantum mechanics.
Supersymmetry is a theory which stipulates that for every known particle there should be a partner particle. For instance, the electron should be paired with a supersymmetric ‘selectron,’ quarks ought to have ‘squark’ partners, and so on.
Boron is carbon’s neighbor on the periodic table, which means it can do a passable carbon impression and wriggle its way into the matrix of a diamond. But it has one fewer electron, so it can’t quite form the same four perfect bonds.
If we are ever to cross the 100-nano barrier in electronics, we need to develop nano structures that let electrons move through, as they do through wires and semiconductors. And these structures must survive in the real world of air, water, boiling temperatures.
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.
Now if this electron is displaced from its equilibrium position, a force that is directly proportional to the displacement restores it like a pendulum to its position of rest.
We had to understand things like why the top quark was so heavy and the electron is so light. The Higgs is a big, important step.
In 1956 we observed the electron antineutrino.
When, in 1949, I decided to join the little band of early explorers who had followed Albert Claude in his pioneering expeditions, electron microscopy was still in its infancy.
Now all oscillatory movements of such an electron can be conceived of as being split up into force, and two circular oscillations perpendicular to this direction rotating in opposite directions.
Among advocates for life after death, nobody even tries to sit down and do the hard work of explaining how the basic physics of atoms and electrons would have to be altered in order for this to be true. If we tried, the fundamental absurdity of the task would quickly become evident.
In the absence of a magnetic field the period of all these oscillations is the same. But as soon as the electron is exposed to the effect of a magnetic field, its motion changes.
Words can have no single fixed meaning. Like wayward electrons, they can spin away from their initial orbit and enter a wider magnetic field. No one owns them or has a proprietary right to dictate how they will be used.
In basic research, the use of the electron microscope has revealed to us the complex universe of the cell, the basic unit of life.
Electrons are the carriers for electricity, but they are also carriers for thermal energy. This means thermal conductivity is increased when the carrier density is increased.
It seems to me, thinking of it, that there must be some universal plan which set in motion the orbiting of the electrons about the nucleus and the slower, more majestic orbit of the galaxies about one another to the very edge of space.
