Paulibus said:Uneasily, I can't agree with Marcus' statements (e.g. post # 59) along the lines of "There is no one unique official mathematical description of reality". Instead, I maintain that the very purpose of physics is to devise such storied descriptions, quantified with the invented language of mathematics, which cleverly includes the statistical concept of quantified probability.
Certainly physics has (so far) sought a unique structure that accounts for the disparate observations of all observers. In fact, the symmetries of the unique structure that we base so much of our physics upon are the result of precisely the demand for this accommodation. And, as I said earlier, QM uses the unique structure from classical physics to apply its formalism. Without such a common reference structure, I don't see how you can verify anyone else's experimental results. So, again, I'm left to wonder how the QBist sees the common set of worldtubes in M4 of classical physics resulting from quantum events when the quantum events themselves defy placement in such a unique structure.
