The entropy of systems

GD, It would be good to avoid chicken/egg questions like where light or energy comes from-like matter it just is. But, there is hope that more can be learned about it. There is energy and matter and they co-exist in what we call the universe. It seems matter interacts with energy in many ways having many effects. Heat and motion are effects of the interaction and light is pure energy. Energy also appears as radio waves, microwaves, infrared radiation, ultraviolet light, x-ray radiation and lots of other names-its all energy that is observed outside of matter. Heat and motion are effects of an interaction observed in matter. The point is these concepts are not clearly understood in science and using rules that apply to one of these concepts in a careless way leads to false answers. Heat clearly is not energy for example and using the rules that work very well where heat exists on energy problems is wrong. There are many examples of this being done in science and it leads to confusion.

Hi Jim,

For all the inventions that humans have produced over the last 100 years, would you say that these were made using physical laws which also apply to nature (or do they apply only to humans?)
For example: you mentioned that the definition of "work" seem to apply only to humans.

Heat and entropy, according to you, are human terminology which have no consequence in certain physical phenomena ?

In which subjects do heat and entropy not apply?

In a previous post, there was a mention that entropy is a physical characteristic of energy. Are you saying that it is not the case for matter?

Gd, Its clear you have more problems understanding me that I have understanding me. So lets say you are better at this and I can stop trying to explain stuff that you know better than I.

Jim,

I think energy transfer within matter is what causes a system to evolve. Without energy transfer motion would not be possible (from electron motion to planetary motion)

How else could nature cause motion? The energy has to come from matter itself. It seems the more massive the body is, the quicker the energy transfer takes place (example: the sun)

Therefore I think energy (light... etc.) comes from matter.

Does this sound right?

hello Jim,
I found this on the web:

"The production of energy ... is the reason why stars shine so brightly..."

The production of energy from what? Is this what we are questioning?

GD, How stars work is yet another detail that makes me take a dim view of common beliefs. As you know everyone knows stars use a fusion model designed by some guy in 1940 of so. But, I don't believe stars work that way. Nature would not use that poor design. Of course thats just me-I really do not think nature follows the rules setup by someone just because everyone else believes it does. I don't what to get into an "is too/is not" debate any more about it so I never try to present a different idea about how stars work.
