Temperature is only one facet of the total energy state and is simply insufficient on its own to get the job done. I know, we thought the same thing and burned the crap out of ourselves in the shower.

We can't alter the universe's laws for our convenience - we tried, doesn't work. :)

And from the universe's perspective, a temperature scale that's built off a particular kind of matter within a certain range that's convenient for weird ape-people on a specific planet on a specific star is no way to run an entire universe.

Now I'm sad the free awards disappeared. Great answer 🏅

Thank you for the clarification on those being numbers for people whose viral load is not suppressed. And the data.

Very interesting, thanks this is helpful! Yes, I suppose in the real world there are a lot of additional factors that need to be considered as well (such as the actual uniformity of the glass, etc.)

Most studies just use ART usage as a proxy for viral load but it makes a huge (>90%) risk reduction.

Another quality reply, thank you.

So… if you’re in the mood, what do you rank as the #1 plausible reason for QM/particle behavior when observed? Have you heard of the many worlds theory?

I have no clue but it is thought provoking. Lots of discussion about how it isn't a physical phenomenon. But what I find interesting is that when interfacing with the electromagnetic wave the length of your antenna matters a great deal. When talking about wavelength, it certainly has some correlation with a measurable physical property.

Kind of interesting stuff.

Well, the person I was replying to was talking about light in general, not a single photon. This is something I only have basic knowledge about.

Interactions with stuff does change it in one way or another. The way the sky is blue is light interacting with air, and tinted glass changes the light going through it. I don't know the mechanics, but that's a change in the photons without changing total speed.

Most of the time: using computer programs based on quantum-mechanical equations to predict the outcome of chemical reactions. You can also predict the properties of molecules and materials.

Quantum mechanics is best understood with a solid grasp of classical wave mechanics.

If there were two water waves in different locations, it's easy to keep track of them, even if they momentarily cross. But if there were two travelling together in the same direction -- is that still two waves? If they then separate, which one is which? This is what indistinguishability means.

Photons are fundamentally just bumps in the global electromagnetic field. When the bumps are well-separated, we can say this is bump 'A' and this is bump 'B'. When they are close, or moving together, or interfering ... those labels are not possible.

> A quality answer and even some better added mystery. Nice! Well done. So, why do physicists fight about that? Is it actually unsettled science?

It's not as mysterious or unsettled as portrayed -- rather it is a case of using non-specific language when trying to simplify for students or laypeople, leading to confusion. The math is exact and well tested. Have a look at my direct reply.

As for interpretations of quantum mechanics -- that one is unsettled. We know the math of QM works very well, but we have little idea what physical meaning (if any) to assign to a lot of the intermediate operations we do in a calculation. Ars Technica recently published a decent article on the topic.

Right, and I didn't contradict you on that, I'm adding to your answer there. The only mistake you made here was you have confused GR and SR.

Hi, I am the owner of those videos and a new member of this forum. I will analize it more. It is strange effeck and works with any metal around the radio. So I think it is not the coating doing this effect.Looks like it is not static electricity effet, The time is too short in between sparks to get it re-charged.

As far as I understand you, you're asking two different questions.

> So if photons travel through a non-vaccum medium by being absorbed and re-emitted, how the heck does the information travel through that medium? Who tells the emitting atom to generate photons of exactly this frequency and polarisation in exactly that direction? How does it actually generate that frequency, e.g. the 432.1THz of a ruby laser when passing through a pane of glas?

This is the wrong type of "absorbed and re-emitted". Photons are not completely absorbed and then re-emitted by a single atom, like you get when you cause fluorescence or something. See my longer explanation. So while you are correct to worry about random direction or energy in the case of classical particle absorption and re-emission, that's not what's happening.

> If one adds unspecific energy to the same piece of glass, i.e. melts it, it glows in yellow or white. Is there any way to make that glass emitting photons of a certain frequency except shining the right frequency into it?

If you had just a tiny amount, like a few atoms, of glass, you would pretty much only see photon emissions at their characteristic energy levels (associated with electron shells, vibrational modes, etc). But as you add more and more atoms, the modes get washed out and photons get absorbed and re-emitted within the glass itself many times before finally emerging (here I am talking about complete absorption and re-emission) such that the final spectrum always looks like black-body radiation. That's why objects of a certain temperature end up looking like certain colors.

I specifically talked about how there are models where the photon becomes a quasiparticle in my original answer to the question, I was simply explaining to the person who asked why there are complications when viewing EM waves moving slower.
