What remains amazing is the negative amplitude of probability, but then that is what I show being still possible thanks to the presence of an arithmetical quantization in arithmetic, at the place we need the probabilities.

I don't recall you having shown that.  Can you repeat it.




By a result of Goldblatt, you have that QL proves A iff the modal logic B proves some transformation T(A), defined by

T(p) = []<>p (Which Rawling and Selesnick called the quantization of p), p atomical sentence (that is arithmetical sentence without quantifier and variable, like s(s(0) + s(0) = s(s(s(0))).
T(A & B) = T(A) & T(B)
T(~A) = [] T(~A)

This makes the modal logic B a classical modal rendering of quantum logic, a bit llike Gödel and others saw that S4 was a classical epistemological rendering of intuitionist logic. The Kripke semantics of B is symmetry and reflexivity: B's main axiom are A -> []<>A, and []A -> A, the accessibility relation is symmetrical and reflexive. Note that the complement relation with alpha R beta iff NOT (alpha R beta) gives a proximity relation, and an abstract orthogonality condition. If the arithmetic material hypostases, defining "the probability one" for the FPI on the sigma_1 sentences (roughly, the UD*) dis not have such an abstract orthogonality conditions, then classical comp as I defined it (in AUDA) would be refuted. Now, I showed that the arithmetical hypostases (S4Grz1, X1*, Z1*) does verify that orthogonality conditions, on the sigma_1 sentences, despite the modal logic is bot a weakening of B (we loss the closure for the necessitation rule), and a strengthening we get new axioms (like we get the new Grz for the internal solipsist, the first person, or Pltinus' universal soul).

Those logic verifies the two main axiom of B, and suggest that the bottom physics, which sums on all sigma_1 sentences, is indeed symmetrical, linear, reflexive, ... let us say that we can hope for some "Gleason theorem" there, which would determine entirely the measure on the directly accessible sigma_1 state.



Do you show that the Hilbert space of QM must be over the complex numbers? Or does your proof allow quaternion or octonion QM?

You know I share with Ramanujan (and thanks to him) some love for the number 24, so I would be happy if the Octonion, a famous divisor of 24 could play some rôle, but that, I would say, has to wait for the "Gleason theorem" of the introspective physics of the universal, and Löbian, machine.

I do have argument for octonions playing some key role, but I keep them for myself, because if the number theorist find physics before the theologians, theology could sleep again for one millennium or more. I can imagine a number theoreticalism capable of eliminating consciousness too (thats' why I am reassured that David Nyman avoided that trap consciously or explicitly so).

Come on, Brent, the greeks discovered the Automobile of "Science", to explore deep questions, they use it from -500 to +500. After that it was declared illegal in Occident, so to speak. We get half of it back at the enlightenment period, and I am just pointing that computer science + the computationalism offers the second half, or at least a second half. I am only the guy who tries to restart the Automobile, that is science including theology, the mother of math and physics (before the political pseudo-religious recuperation).

You ask me if QM is octonionic ? There are now two questions: what does nature say? and what does the universal machine see in arithmetic from inside. And we can compare, even if today it requires "hard math" like the modal logic of arithmetical (and non arithmetical) self- references. Good textbooks exists, as I have given references.

Keep in mind we try to figure what happens, not how to make bombs and rockets. We want just a coherent picture of the possible whole, and this without eliminating persons, consciousness, etc.
