Excellent reasoning.I just disagreed with your final caveat that it is only a modeling and no representation of actual reality; or is it the usual PR necessary to do physics? Even General Relativity is said not to represent reality,so why bother!

Hi Anon,

Thanks for the feedback. I do not get much and appreciate it.

"Why Bother?" I think would make a good essay question for the next contest and is as fundamental as it gets. Personally I wonder why I dapple as an amateur in physics. I think it is a mixture of ego, wanting to help others, and it just comes with the package that is human.

As I see it we humans seem to make models of "what is" and then defend these models against the models of "others". This seems to enhance our survival as a species. And "why bother" is a very good question.

"Is PR needed to do Physics?" is also an excellent question. I think so, but many do it without a sense of ethics and give PR a bad name. As an example I would point out the current essay contest in which a lot of self promotion goes on, some of it skillful some not.

Thanks again,

Don L.
