I agree it is faith, but it is less faith than any scientists. Especially that 
we need only a tiny part of the arithmetical truth. 

Did you have heard about someone taking back his/her children from primary 
school when they are taught the laws of addition and multiplication, by 
claiming they have not that faith?

The approach just study the necessary logical consequence of assuming our 
bodies to be digitalisable.  I predicted all the quantum weirdness from this 45 
years ago. But then it took me 30 years to get precise mathematical 
predictions, which until now fits with the fact, when physicalism needs a 
brain-mind identity thesis which has been shown inconsistent. 
I am not sure why you say that Mechanism cannot work for physical and 
biological issues. You might confuse the computable (like automata), and the 
semi-computable (like the universal Turing machine).

What do you mean by “real world”?
I agree Euclid geometry is in our head. The whole physical reality is indeed 
shown to be “in the head” of *any* universal machine or universal number, etc.

For a logician; Everett is the Herbrand model of the Schroedinger equation, 
that is QM without the unintelligible “collapse” of the wave. Put simply: the 
“many-world” is just literal quantum mechanics without collapse.
Everett did not propose a new speculative theory: he just showed that we don’t 
need the collapse axiom, as QM + mechanism recovers it phenomenologically. Then 
my work shows this can work only if we recover also the wave itself from 
arithmetic (or Turing equivalent).

It is the collapse which is bad and unclear, and not needed, untestable,

What I did has been peer reviewed and verified by many people. Have you read my 
Did you find a problem, or are you just criticising the assumption/theory? Ask 
specific question, but normally all this has been clearly proofed.

I prefer to invoke the physical reality only for the testing. There is some 
possible analogy here, which might be interesting, but Mechanism is an 
hypothesis in psychology, or theology, not in physics, which needs to be 
entirely recovered from arithmetic (or Turing equivalent). For this type of 
Mechanist (Neo)platonism: looking at the physical universe is … cheating.

I have decided to study Mathematics for just that. My thesis is a PhD in 
mathematics and theoretical computer science. All what I say has been 
translated entirely in arithmetic, by using Gödel’s technic of arithmetisation 
of metamathematics. I got testable quantitative result which have been tested. 
I am not sure you have study my work, which is usually criticised for being …

? I predicted the non-cloning theorem 30 years before the physicist get it, and 
much more. 

Please study my papers before judging(*)

The logicians are the one who discovered the universal machine (computer), 
before it was build. You are using one just now. You seem to ignore Gödel’s 
contribution, which in my opinion is, when we assume mechanism (the older 
metaphysical/theological assumption)  the most important result ever discovered 
by the humans.

> Sorry again! 

You don’t need to be sorry, but my feeling is that you are not aware of the 
result that I got. It is science, which means that it is not a question of 
agreeing or disagreeing, but of understanding or refuting.
Maybe you could study the following papers (if interested):

Biophys Mol Biol; 2013 Sep;113(1):127-40
