This leads to the most interesting question: what is geometry?
A lot of people, like Lucien Hardy or Russell Standish try to "derive" QM
from basic assumptions but most such attempts take some geometry for granted.
In some sense Descartes tried to make arithmetical foundation
for geometry and this has lead to the well known coordinate systems, and then
physics look like finding invariant for coordinate systems changes...
Coordinates give indeed number-representations of things, but we
better should not take those things for granted. In any case the comp
hypothesis forces us
to generalise Klein program for geometry (reducing it to symmetry (group)
theory), making the logical structure of
reality invariant for any change of point of view ...
  With comp the UDA shows we
must go from number to consistent comp histories then measure (and statistic
on those histories, and only then we can hope to find a way toward ...
What? commutative geometry above our common level of substitution, non
commutative below. I bet.

You cannot be serious. Most quantum weirdness can be described with
two dimensional real vector space and their products.

Perhaps you are dreaming about building a non abelian anyonic quantum
computing machine through some fractional quantum Hall effect?
This is less elementary.

Hold on I feel myself belonging to the Reality view as you know. I
do indeed not quite belong to the" Physical Reality" view cause I think
Physical and Psychological are two internal views of number theoretical truth.
That does not mean I don't believe in the physical laws, it means only that I
don't believe physical laws are necessarily the fundamental laws.

I showed comp force us to derive (aspect of) the laws of
physics from a measure on the consistent machine "dreams".
I should get QT from the other side. I find indeed firstly
the many worlds, then, thanks to the consistency requirement
a sort of abstract geometry appears and I compare
it with the quantum for just verifying comp, or perhaps measuring
some sort of local degree of falsity of comp, who knows?

Even if Freedman or Calude are right and that it exists some
analogical quantum universal machine that would not entail the falsity
of comp. Only if we find evidence that we are ourself such analogical universal
machine then comp would be false. I would not bet on that ... today.

I read Piaget and Oliver Sacks too. It is interesting and inspiring but
remember I talk on the psychology of the sound universal machine. Actually
I just interview such machine (thanks to Solovay) *about* those different
possible (consistent) points of view.

Please wait I write a longer english paper but I have still some work
to finish before.

But I don't start from QT and, in fine, my "philosophy of mind" is just
classical logic, remember Boole called his book "the laws of thought".
Since Godel Lob we know that that psychology has much more intricateness
due to powerfull self-reference capacity.



>A. ASKING THE OLD AND WRONG QUESTION IN QT

I don't ask any question in QT. Only in computer science and self-reference
logic.

Please I do not *assume* that I can get physical context from math
but I do *prove* that if comp is taken seriously then comp is wrong or the
physical modalities does come from the math. (And I extract a little non
trivial bit of those modalities).

Y're welcome. But remember I am not proposing a theory but only a theorem.
(I could be wrong but please tell me where!)
Ant it comes from a very well shared "theory" (comp). It is Everett's
and David Deutsch's theory of mind BTW.
It is not a matter of choice.
Comp implies the laws of physics MUST be derivable from numbers. Not in the
trivial way that QM can be formally related to the relation between *some*
numbers but in the non trivial way that QM emerges from all possible relations
between *all* numbers.
I don't know and don't really care if comp is true or not.

Curious. I don't believe any theories can fill fully the number realm (and that
is a consequence of Godel).
But concerning the physical I would bet on some deep completeness of QT, this
mainly for statistical reason. I would bet QT complete and more than
universal, multiversal actually.

??? I talk a lot about that in my thesis and paper. It is the building
block of the reasoning. Although I prefer to duplicate the whole brain
for making the split perfectly symmetrical. It is the root of the first
person comp indeterminacy which eventually force us aknowledging our
ignorance about which sheaves of computations we belong.

Ok the 99% argument is bad, but I was not really pretending the community
  believes in bivalent logic just that bivalent logic is the simplest
frame for communicating propositions on fundamental questions including
those on non bivalent logics and their models.
I said once classical logic is just the most polite logic. Probably
because it can take into account that very non constructive notion: the
other.
