I have tried to study the UDA but lack sufficient understanding to see how the UDA could compute an infinite number of paths or universes as in the diffraction example I discussed.

I will remind this in later explanations. Dovetailing is a technic allowing to emulate digital parallelism with a single processor. The basic idea is that you can back again and again on the initial programs. You go through the programs p1, p2, p3, ... in that way:


p1, p2, p1, p2, p3, p1, p2, p1, p2, p3, p4, p1, p2, p1, p2, p3, p4, p5, p1, ...

and each time you emulate for some finite time the activity, and you save the "continuation" to resume that computation at the next meeting in that listing.

In that way, you will run all programs, even all those which never stop.

If you wait long enough, you will get the emulation of the linear evolution of the rational heisenberg matrix describing the Milky Way Observable, at all substitution level possible, and thus emulating notably many diffraction processes.

Church thesis ensures that you do enumerate all programs with the pi, once you have chosen a Turing universal system (like LISP, or the game- of-life pattern, or just some degree 4 diophantine polynomial).

Telmo,

I can only give you my opinion. You are of course referring to the double slit experiment where one photon can follow at least two different paths, and potentially an infinite number of paths.

But even diffraction of a single photon will do that: in the simplest case send a photon on to a semi-infinite metallic plane and the photon potentially scatters into an infinite number of paths from the edge of the plane. We only know which path when the photon reaches a detector plane on the far side. The actual deterministic diffraction pattern only emerges when the number of photons sent approaches infinity in plane waves. The actual path of a single photon is random within the constraints of the infinite- photon diffraction pattern.

So I say the way to deal with that is to propagate a large number of photons or do an EM wave calculation for the diffraction pattern.

I wonder how comp treats such single photon instances. Does it use algorithms that are random number generators?

No, it uses the first person indeterminacy in self-multiplication, which explains where the quantum wave comes from. I have explained this on this list and published it a long time ago. That is why I told you that if you take comp into consideration, you must derive QM and perhaps string theory (if it is correct) from addition and multiplication of the natural numbers. I see you have not yet studied or grasped the UDA :)

Hi Richard,

Ok, but in that case physics is deterministic, just hard to compute.
How do we then deal with the fact that two photons under the precise
same conditions can follow two different paths (except for some hidden
variable we don't know about)? I'm not a physicist and way over my
head here, so this is not a rhetorical question.
