New Theories / Re: what is temperature?

They show that the concept of temperature is not as well defined as some of us might have thought.

No. It shows that the source of the quotation doesn't understand the definition. Probably a "philosopher of science".

The articles I quoted show different versions of temperature.

What's temperature?
Quote
Temperature is a physical quantity that quantitatively expresses the attribute of hotness or coldness. Temperature is measured with a thermometer. It reflects the average kinetic energy of the vibrating and colliding atoms making up a substance.

https://en.m.wikipedia.org/wiki/Temperature
The article above also mention kinetic temperature and internal temperature.
In contrast,
Quote
Thermodynamic temperature is a quantity defined in thermodynamics as distinct from kinetic theory or statistical mechanics.

The same object may have different temperature, based on which method is used to measure it.

That doesn't mean we don't understand temperature.
It means that we understand that there are things to which it does not apply.

Can you describe what those things are?

The question is, which object is the hottest?

The electrons in the LED with an energy of a few electron volts, corresponding to a temperature of tens of thousands of kelvin.

Does it melt?

Whenever I want to

Whatever is under my control

Ignore them or kill them.

Getting them under control is the problem.

And it's going to get worse, the question being if you're going to notice, so stuck in your visions.

It's pretty easy to see how our 'visions' becomes a result of our own living standards, way of life, as when talking about how to live longer and healthier, in the West. The Guardian no exception. Presuming that this is a global golden standard.

In a way it is though, everyone playing the same game, wanting the same as what we have. But it is still a lie.

Agreed. You know my obsession with pedanticism(pedantry?). I think we can now close this question with your last sentence.

That's a bit like saying that, because you can't divide by zero, we don't understand division.
We can't say what the temperature of a non thermal system is.
That doesn't mean we don't understand temperature.
It means that we understand that there are things to which it does not apply.

We can't tell you the thermodynamic temperature of the inside of a fluorescent light bulb when it's running.
We can't tell you the temperature of love or Thursday either.
That's not because we don't understand temperature.
It's because we understand it well enough to realise when it does not apply.
