Quotes About Electron

In the early days of atomic physics [before quantum field theory revealed the true meaning of the fine structure constant to be the strength of the coupling between the electron and photon], it was thought to have a value so close to being precisely 1/137 that numerologists started to establish cultish associations with the number 137.

The solution to Schrödinger's equation shows that a small portion of the electron probability wave exists on the far side of an impenetrable barrier.

Fine Structure Constant: Fundamental numerical constant of atomic physics and quantum electrodynamics, defined as the square of the charge of the electron divided by the product of Planck's constant and the speed of light.

Quantum mechanics has a similar problem, a problem related to the zero-point energy. The laws of quantum mechanics treat particles such as the electron as points; that is, they take up no space at all. The electron is a zero-dimensional object, and its very zerolike nature ensures that scientists don't even know the electron's mass or charge.

And there is the fact that what matters is not how things are, but rather how they interact. Spin networks are not entities; they describe the effect of space upon things. Just as an electron is in no place-is diffused in a cloud of probability in all places-space is not actually forned by a single specific spin network, but rather by a cloud of probabilities over the whole range of all possible spin networks.

Ama bütün çocuklar gibi kuram da kendi yoluna gitti, Einstein da onu art?k tan?yamaz oldu. 1910'lar ve 1920'ler boyunca büyümesine yön verense Danimarkal? Niels Bohr oldu. I??k enerjisi gibi atomlardaki elektronlar?n belirli bir enerjiyle yaln?zca bir atom yörüngesinden di?erine "s?çrayabilece?ini", bunu yaparken de bir foton sald???n? veya so?urdu?unu anlayan odur.

Tanto los protones como los neutrones están hechos de partículas aún más pequeñas, que el físico estadounidense Murray Gell-Mann bautizó con el nombre de «quarks», inspirándose en una palabra sin sentido en una frase sin sentido —«Three quarks for Muster Mark!»— que aparece en el Finnegans Wake de James Joyce. Todas las cosas que tocamos están hechas, pues, de electrones y de estos quarks.

The probability of finding an electron or any other particle at one point or another can be imagined as a diffuse cloud, denser where the probability of seeing the particle is stronger. Sometimes it is useful to visualize this cloud as if it were a real thing. For instance, the cloud that represents an electron around its nucleus indicates where it is more likely that the electron appears if we look at it. If you have encountered them at school, these are the atomic orbitals.

The "quantum leaps" from one orbit to another constitute their way of being real: an electron is a combination of leaps from one interaction to another.

The theory also gives information on which value of the spectrum will manifest itself in the next interaction, but only in the form of probabilities. We do not know with certainty where the electron will appear, but we can compute the probability that it will appear here or there.

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.

The leptons most familiar to the non-physicist are the electron and perhaps the neutrino; and the most familiar quarks are . . . well, there are no familiar quarks.

All molecules pulse with vibrations. They shimmer and wiggle and sing with the vibrations of the electron strings that hold them together, which means molecules are, oddly enough, a sort of musical instrument.

two atoms are walking along. One of them says, 'Oh, no, I think I lost an electron.' 'Are you sure?' says the other. 'Yes, I'm positive.

atoms change their charge from negative to positive when they lose an electron.

In 1956 we observed the electron antineutrino.

But, even if the quantum state gives us only probabilities for what we observe, once we get a result, there is something that is definite, because afterward you know exactly what the state is. It is the state corresponding to the result obtained by the measurement. Suppose we measure an electron's momentum, and get the result that the electron is moving north with momentum 17 (in some units). Then, just after the measurement we know that the

com o correr dos séculos perdi o segredo do Egito, quando eu me movia em longitude, latitude e altitude com ação energética dos elétrons, prótons, nêutrons, no fascínio que é a palavra e sua sombra". Isso que te escrevi é um desenho eletrônico e não tem passado ou futuro: é simplesmente já.

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 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.

All of the lightest stable quarks and leptons have heavier replicas. No one knows why they are there, or what they are good for. When physicists first realized that the muon, a particle first seen in cosmic rays, was nothing other than a heavier version of the electron (200 times heavier), the physicist I.I. Rabi asked, "Who ordered that?

I think that a particle must have a separate reality independent of the measurements. That is an electron has spin, location and so forth even when it is not being measured. I like to think that the moon is there even if I am not looking at it.

Fat, such as olive oil, can be stored on your body within minutes, without costing the body any caloric price; it is just packed away (unchanged) on your hips and waist. If we biopsied your waist fat and looked at it under an electron microscope, we could actually see where the fat came from. It is stored there as pig fat, dairy fat, and olive oil fat—just as it was in the original food. It goes from your lips right to your hips. Actually
