Sure, but before having that future science we must use some terms.

As I said in the first UDA posting http://www.escribe.com/science/theory/m1726.html, it is really the

proof that "physics is a branch of psychology" which provides the

explanation of such terms. Basically machine psychology is given by all

true propositions that machine or collection of machine can prove

or bet about themselves.

Eventually it is given by the Godel Lob logic of provability with

their modal variants. I take the fact that a consistent machine

cannot prove its own consistency as a psychological theorem.

Consciousness can then be approximated by the unconscious (automated,

instinctive) anticipation of self-consistency.

Perhaps. I guess a sort of adjunction, or a Chu transform? I don't know.

You can click on "proof of LASE" in my web page, and on Modal Logic

if you need. The technical part of my thesis relies on the

work of Godel, Lob, Solovay, Goldblatt, Boolos, Visser. Precise

references are in my thesis (downloadable, but written in french).

You can also look at the paper "Computation, Consciousness and the Quantum".

When I will have more time I can provide more explanations.

Let me insist that that technics makes much more sense once you get

the more informal, but nevertheless rigorous, UDA argument.

Regards,

Bruno
