They did rewrite the second law at Georgia State.It is no longer big news. It was rewritten over 100 years ago in terms of entropy. Tell me how the second law written in terms of entropy disallows radiation from a colder body to a warmer body. (Note that the warmer body radiates more to the colder body so the net energy is from the warmer to the colder.)Like I said goober...you be sure to tell me when they rewrite the second law of thermodynamics to relate energy transfer in terms of net as opposed to gross energy movement....it will be big news...but let me know anyway.
Lying doesn't make it true...if it were as you say, surely as respected a physics department as that of Georgia State would be aware and write it properly...
Science wins over pseudoscience. Because of the misunderstanding SSDD had on the second law of thermodynamics, I wrote a letter some time ago to Georgia State concerning their hyperphysics site. This is correspondence I had with Georgia State:

Dear XXXXX,
There is a difficulty with the hyperphysics site that you are probably not aware of. Many people quote it as an authoritative source, including me.
However some people try to prove back radiation in greenhouse gases doesn't exist because photons (which have energy) cannot travel from a cold object to a warm object. They conclude global warming is a hoax. They get that from the page:
Second Law of Thermodynamics
There is a statement, under "Second Law: Refrigerator."
"Energy will not flow spontaneously from a low temperature object to a higher temperature object."
That statement is true for refrigerators, but they interpret it to mean photons can't back radiate from a cold atmosphere to a warmer earth.
It would really help if you made a very simple change ....
Thank you

I got got a reply from them. I didn't ask permission to quote them, so I won't. He apologized for the long delay in his response and told me that he added a brief statement.
Here is their updated site. Note the added paragraph that clearly spells out the fact that there is a two way flow of energy for radiation and particles, and the site refers to net energy of that two way flow.This illustrates a gross misunderstanding of SSDD and his minions of what the second law means. And that allows back-radiation.
