Tom,
I think we are getting to the heart of the problem. You make two statements that I find incredible:
1) "If numbers map 1 to 1 with time intervals, as you say, there is absolutely no difference between the number sequence and the time sequence. They are identical. Particularly, as you claim that "physical logic underlies math." Things that are not differentiable are identical in physics; e.g., the vacuum and the ether."
and
2) "Physics absolutely does support contradictions -- all the time. The most fundamental contradiction is between quantum theory and general relativity."
Perhaps I have been careless and said "physics" when I meant "physical reality". I try to maintain the distinction. I don't care that "physics" is contradictory, since it is clear from the state of today's physics that all of the current models, from the Standard Model to General Relativity are in big trouble. Lev thinks it's because of problems in math, I think it's because of problems with physical concepts.
I've remarked in several comments that the dividing line as I see it is between Unitarists and Dualists, loosely defined as those who believe in one physical substance from which the world self-evolves, and those who believe in some Platonic world of math that replaces God in governing the physical world.
Those who believe in the Platonic world of math can make statements such as yours, that if two entities map into each other, 1-to-1, they are identical. Mathematically perhaps true, physically false.
I have come to believe that those who live in the 'mental' world of math and logic have, to a serious degree, actually lost touch with the physical world. Drastic, I know, but it's the only thing that I can comprehend that explains the general view which I think you are expressing.
So when you say "Physics absolutely does support contradictions -- all the time" you should notice that I said: "the most basic property of the physical universe is logic, in the sense that physical contradictions do not exist." Either you are not paying attention to the words, or else you do not distinguish between "physics" and "physical reality". Contradictions do not exist in *physical reality*. The fact that they may exist in physics should simply be considered as proof that physics is off the mark.
I don't know whether we have a language problem or, as I suspect, a more serious perceptual problem, which I believe is reflected in both these fqxi discussions, and in the wider world of politics, where there appears to be a large percentage of humans who cannot (or do not) distinguish between abstractions and reality. Math is abstraction, physical reality is not.
I do appreciate your comments,
Edwin Eugene Klingman
