Pure physics is a branch of mathematics. But without evidence that the real world actually behaves that way, it's worthless. Applied physics is the search for that evidence.

I find, however (like Dawn, I think), that most proponents of relational theory treat it purely as mathematics, and are almost offended when I try to say "where is the SCIENCE of 'applied relational theory'?". Without that, there is no evidence that relational theory actually has any relevance to the real world.

I'm used to trying to explain myself to non-computing people. I'm often complimented on how I make myself understandable by using analogies. My use of "nouns and adjectives", and Newton, etc etc, is simply an attempt to make my point using such analogies.

(And I'm not against maths. It's just that science is all about fuzzy logic, uncertainty, and statistics. But (a) my grasp of the fundamental theory behind that is very poor, and (b) it seems to be a lot better than anybody else who might be inclined to debate with me. I'm just looking for *scientific* proof, not mathematical, that relational theory works, and nobody seems willing to try to prove it.)
