Quote from: Bored chemist on 14/12/2024 23:27:48I see that, for example, you still think that quoting chatGPT is somehow useful.By asking them the same question at different times, we can see how they learn. Or how mainstream science shift its paradigm over time.

That's nothing to do with the topic, is it?
Thermodynamics hasn't changed much in 50 years.The definition of temperature is essentially even older.
The interpretation of probability is a disputed topic in philosophy. But shouldn't physics, as an objective study of nature, be devoid of terms like probability at the fundamental level? Surprisingly, this is not the case. Probability plays a fundamental role even at the level of classical physics. In this video, we explore how Maxwell and Boltzmann brought probability to explain thermodynamic concepts such as entropy, pressure, and temperature. Since then, physics hasn't been the same.

Planck's approach to Blackbody Radiation was to analyze the entropy as a function of energy. To make both high-frequency and low-frequency data consistent with the Second Law of Thermodynamics, he included an additional "guess" term proportional to the frequency (hf); this results in Planck's Law which is strictly Classical. Planck's subsequent application of Boltzmann's Statistical Mechanics to justify his guess then led to his revolutionary conclusion that the material of the walls emit and absorb radiation in discrete quanta. A paper titled "Planck?s Route to the Black Body Radiation Formula and Quantization" by Michael Fowler (7/25/2008) gives a nice discussion. "Theoretical Concepts in Physics: An Alternative View of Theoretical Reasoning in Physics" (1984) by Malcolm S. Longair contains more details.
Surprisingly, this is not the case.
. AI models will be the first reference for most people to get their information when they need it.

It will be important to know their differences and similarities.

If they are not all talking about the same thing, then some of them are wrong.
As the term is borrowed from thermodynamics, it should be used in inverted commas and specifically redefined for any other use.

The term temperature was already widely used before thermodynamics.
Aside from the fact that you just proves that they are not sources of information (The references are the sources), why don't you ask then?And then you can quote those sources and we can judge them.
Quote from: hamdani yusuf on 16/12/2024 15:17:55The term temperature was already widely used before thermodynamics.I very much doubt is its use in telecommunications derives directly from the physiological phenomenon or the etymology of the word, but has a lot more to do with statistics and entropy.
In summary, antenna temperature is a key concept in understanding the amount of radiation an antenna receives, which can represent either signal or noise, depending on the application. It helps quantify the effective power of this radiation by linking it to the temperature concept, facilitating better analysis and system design in both astronomy and communications.

A thing that makes up nonsense is not a source.
