If you ask for a source, you are probably not thinking.

A source is nothing more than the opinions of another. They could be right or wrong, just as any other making an argument.

Yes...even if they are professional scientists.

An argument is reasonable (or not) no matter its source.

We use sources to make our arguments because it is totally impractical to derive every new argument from scratch. Do you think, for example, that aircraft engineers feel the need to explicitly derive Newton's laws of motion every time they propose a new wing design?

In addition, for definitions and such, sources are necessary to show that at least one other person uses the definition you are claiming is the only true meaning.

In science, we're all wrong. Nobody can predict perfectly, and our theories are probably only shadows of the truth. But the accepted models and theories tend to be closer to the truth than anything that came before.

But unless you perform the experiments yourself or refer to the work of others, you'll never know what is science (your definition) and what isn't.

Take, for example, your assumption that gases emit radiation in accordance with Planck's Law. You believe this to be science, when just a little research indicates that this isn't the case. How can you know whether you are right or wrong in believing that something is science unless you perform a suitable experiment yourself or trust the experimental results of someone else?

True. What any person accepts as science is up to that individual.

To qualify as science there are some base, absolute requirements:
1. A falsifiable model
2. It must predict nature
3. It must have endured the testing of the scientific method to some extent, with internal and external consistency having been validated and some amount of direct testing of the model's predicting veracity.

On point 3, the extent to which any model has been tested might be insufficient for some people. No one can mandate what anyone is to "accept."

A great example is radiometric dating. Many Christians don't accept it because it is entirely based on an assumption that they are not ready to accept, i.e. that there is always zero decay material at inception.

The fact is that radiometric dating returns the maximum age an artifact can be based on the assumption of zero inception decay material. Any artifact that had some nonzero quantity of decay material at "inception" will be much younger than indicated.

Is radiometric dating science? It meets the base requirements. Unfortunately, the underlying assumption of "zero inception decay material" is itself unfalsifiable. We cannot travel back in time to measure the amount of decay material at the artifact's inception.

On the one hand, I accept radiometric dating as science; however, I cannot fault anyone who does not for the above reason.

If jwoodward48 were to announce that he doesn't accept Stefan-Boltzmann as science then he would be within his right ... but he would be resonponsible for identifying the shortcomings in the work that has been accomplished.

That is not my stated assumption. You are intentionally or otherwise falling for jwoodward48's blatant miswording/mischaracterization/misrepresentation/weaseling of my position.

Planck's law applies to bodies. It applies to all bodies, even those with gaseous atmospheres.

All substances radiate per their temperature (this is where you start to weasel yourself).

All substances have differing absorption signatures.

All substances have differing emission signatures.

Then you are quite simply wrong.

Gases do not radiate according to Planck's law; they radiate at wavelengths specific to the nature of the gas. For example, astrophysicists can determine the nature (as well as the temperature) of interstellar gas clouds by studying the radiation that they emit. Hydrogen, for example, emits strongly at a wavelength of 21 cm, and this fact has been used by radio astronomers to map the distribution of hydrogen in our galaxy.

Planck's says that all substances will radiate differently, that no substance acts as an ideal black body.

Planck's law does not apply to everything; it applies to black bodies.

Solids usually emit light approximately as a black body would, that is, roughly according to Planck's law. This means that, when heated, they emit light over a continuous range of wavelengths. If you shine this light through a prism, you get a continuous spectrum, like this:



Gases, on the other hand, do not emit light according to Planck's law when heated. Instead, they emit light at a series of specific wavelengths. These wavelengths depend on the gas emitting the light. If you shine this light through a prism, you get line spectrum. This is the line spectrum for neon:

I don't know what you mean by mixed apples and oranges here.

That was simply a comparison of what you actually see when you disperse the light from a hot solid and from a hot gas. You can see for yourself how different the spectra look. But yes, here's how the radiated light looks in terms of intensity (power per unit area) vs. wavelength.

This graph shows intensity vs. wavelength for black bodies at different temperatures, from Planck's law:



Most solids will give emission curves looking something like this. You can see how the intensity is a continuous function of wavelength and so gives a continuous spectrum.

While this graph shows the intensity vs. wavelength for neon:



In this case, the intensity has large peaks at wavelengths specific to neon. The large spike at 5852.49 angstroms corresponds to the bright yellow line you can see in the line spectrum in my earlier post. Both the absolute and relative intensities of these spikes change with the temperature of the gas, but their wavelengths remain constant.

Does that make sense?

Of course you wouldn't. You were educated in the UK. You apparently were never taught that a spectrograph shows different things from a graph of wavelength vs. power.

Different things.

...or perhaps you weren't taught the meaning of "apples and oranges."

Different things.

Anyway, I shouldn't have to spell it out for you but you still have not shown how the power per frequency changes as temperature changes for any gas, much less for various different gases, nor have you shown how any violate Planck's law.

Can you find a video, perhaps, of power vs. wavelength of a gas as temperature is changed? i.e. a realtime observation of how the power distribution over the wavelengths changes per the change in temperature?

That would be an interesting discussion. Obviously any single graph/chart that doesn't show what you are trying to conclude is of little concern to me and I'm not going to simply accept your WACKY conclusion based solely on your insistence.

I would be very much interested in a discussion of the power distribution per T that I mentioned above.

The first and second pair of images showed the same thing.

The gases violate Planck's Law because they don't emit black body radiation. I can post an explanation on the quantum level later. But the gas and the black body spectra are obviously different.

Are you working on learning how to cut-n-paste it? The good news is that once you learn that, you can cut-n-paste just about everything.

Of course you wouldn't. You were educated in the UK. You apparently were never taught that a spectrograph shows different things from a graph of wavelength vs. power.

Different things.

...or perhaps you weren't taught the meaning of "apples and oranges."

Different things.

The graph of intensity vs. wavelength that I just posted for neon illustrates that neon does not radiate according to Planck's law. There is no temperature for which Planck's law can give a graph of intensity vs. wavelength consisting of a set of peaks of various heights. Ask a mathematician if you don't believe me.

No it does not. Your graph does not support your wild conclusion, despite your insistence.

Why do you not acquire what I described?

On the topic, what "climate" science have you reviewed and understand convinced you that "greenhouse effect" is real and active in our lives?

I love proofs. That would be great.

Of course it does. How could the continuous function that constitutes Planck's law possibly give the series of peaks making up the neon spectrum? That's possibly the daftest thing you've come out with yet.
