Oh, and I guess I was meaning that the literal definition of the term "physics" was what I am blabbering about... I think it should be considered as the grandaddy of all physical forms of science (the head) and then chemistry, biology, etc would be the "body parts". Like, they should have proper names like Chemistry Physics, but just Chemistry for short. Chemistry is a specialized field of physics, at least in my mind, despite what the dictionary says or fails to say. LOL. Words aren't important to me as long as I understand the semantics of what's said, so no worries.

And yeah I understand what you mean, like how you can't deduce how a person's brain will function just by studying their ears nose and throat.
A weird analogy pops into my mind like... general doctor is to physics as neurologist is to chemistry. Gen doc is limited to just a broad overview of how the body works, while the neuro is also a doctor but specializes in brain functions. Am I sounding crazy yet?
