Quote from: Spring Theory on 03/04/2022 01:07:58Sufficient to say that it is generally accepted that the electron (or its wave function) has a velocity around the proton in a hydrogen atom.Not since 1925. How old are you? QuoteWhen describing what temperature is, it is easier to think of a single hydrogen atom. Beware! The journey to disaster begins with a single step in the wrong direction. Temperature is an ensemble statistic and is not defined for a single atom or particle. You'll add confusion by attempting to "describe" a mathematical function that has a clear definition. Two steps in the wrong direction..... Quote The farther the distance, the lower the potential energy. That's the inverse of the conventional description of potential, and rather surprising coming from a spring theorist.

I'm right on the other points though.
How would you explain magnetic moments without a velocity?
Quote from: Spring Theory on 04/04/2022 00:35:03I'm right on the other points though.NoYou are not.You are using an idea that died a hundred years ago.Quote from: Spring Theory on 04/04/2022 00:35:03How would you explain magnetic moments without a velocity?Good question; but the wrong one.The right question is "how can magnetic moments be produced by velocity when, for an electron, teh velocity required would exceed the speed of light?".The answer is "well- it can't be the velocity then.And there is, as I pointed out, still the problem with the uncertainty principle.Do the maths.Calculate the uncertainty of the velocity of an electron which is confines within the radius of a hydrogen atom.

Laser cutting is a technology that uses a laser to vaporize materials, resulting in a cut edge.
So we usually say that this energy transfer is not a thermal radiation, which raise the question, what is?

Quote from: Spring Theory on 03/04/2022 01:18:54This is a point of debate and speculation (proper for this directory). I would consider the hydrogen atom at its ground state as absolute zero. The next step lower would be to knock the electron off the hydrogen atom, but you're adding energy to the system.Is temperature a quantized value?

It could be quantized as the number of photons (and absorbed photons) in a volume of space.
Thermal radiation is the continuum spectrum of electromagnetic radiation emanating from the random movement of electrons in a hot body. Laser radiation is a narrow spectrum arising from coordinated quantum transitions.

We can filter out some wavelengths from a black body radiation.
How much spectra can be added to a narrow laser spectrum until it starts being a thermal radiation?
