I have noticed that on this site, people who are well versed in philosophy and/or science often revert to speech that could be (or is) inaccessible to others... — dan0mac

All subjects have specialist terminology that only a subset of general speakers of the language (English in our case) will understand without further research. If the terminology is standard enough, and is being used in a standard enough sense by the writer that it can easily be looked up by the reader, I see no problem. For the sake of brevity, and avoiding unnecessarily bloated posts containing lots of explanations that are direct duplicates of other easily accessible sources, I think this kind of accurate use of specialist terminology is useful.

The reason why physics, in particular, has had an impact on philosophical thought is that physics, probably more than any other branch of science, has yielded empirical results which are directly relevant to philosophical questions about such things as the nature of reality, the concepts of objectively and subjectivity, what it means to accumulate knowledge via observation (epistemology), the place of humans in the universe, and so on.
