Dear Telmo
(I suppose a 'freer mind than several nat.-scientist listers) allow me some musings (not that I want to hide them from the rest of the List). Thinking of Bruno's integer-restricted arithmetics with addition and subtraction only:

addition and multiplication (actually, just a detail).



it is the World Of ONE, multiplied as much as you wish (two ways: + and -). Numerals? So we elevated to some understanding of the "ONE" (unit?) and our uncontrollable mind made out of it the Entire World. Or we don't understand even that 'one'; Bruno applied his extremely educated (and disciplined) mind to elevate this 'one' into sophisticated logical systems (what I never studied, sorry to say).

I derived it from the computationalist *assumption*.



There are also opinionated remarks about 'physical' (etc.?) laws with fancy conclusions. In my opinion a physical law is the summation of observations WITHIN limits of our so far achieved knowledge and the 'majority' seems to be the "norm" ('law'). Then comes the condiment: lots of math and similar deductions and voila: our conventional sciences. Extend the limits (of our observations? or knowledge?) and the "laws" change. That happened in our (cultural? human?) history continually. I do not appreciate the level at which we are today: it will change as it changed from the past. Societal (communal?) 'law' is different: it is a compromise between interests of diverse classes of members of a society including the powerfuls' as giving the overtone.

Reality is beyond our (human) mental capabilities to detect,

It is beyond all machine's ability, not just the humans (I assume comp, of course). All machine believing in a reality can discover that indeed most of it will transcend his capacity, even when assuming comp. The ontology becomes very simple (only 0 and its successor, or only the combinators K and S, with their applications, ...), but the epistemology, which include the physics, get infinitely complex and rich.



I humbly disregard the "Slanted Realities" like mathematical, or religious, etc. partial views. Same with truth. I like to talk about my 'agnosticism' and MY beliefs based in it: the 'infinite copmp[lexity' beyond our (limited) model of knowables (because I cannot comprehend "infinite" - or - "complexity" as a simple-minded human).

We agree on this. The nice point is that absolutely all machines, when correct, agrees with this, and discover it by themselves.




So after having passed an old fashioned rigorous Ph.D. at a 5century old Universitas in chemistry, physics and math, published ~100 papers (both in research and technical implementation of own results mostly in the polymer-field) lectured on 3 continents and having gotten 38 patents to my inventorship, I do not believe in 'atoms' (molecules?)

Nor do any correct machine when introspecting enough.



and consider the physical world a 'human' makeup

It is a "machine" or "number" make up. Assuming comp. In that case the reasoning is constructive, which means that the physical laws can be deduced from the machine's (mathematical) points of view, and this makes computationalism refutable. (That is the main point).



for ever changing and poorly understood phenomena as their synthesis into a 'scientifically balanced' conventional view which, however, produced lots of (almost perfect?) practical results into our lives.

Have a prosperous 2014 and then more to come

Happy New Year 2014!

Bruno,

I think I (perhaps naively) understand what you mean. My understanding
is that, if comp is true, then the relationship between comp and the
physical laws we observe is not a simple one. Even QM would be at a
high level of abstraction in relation to raw reality. In this case,
the recursive definition of integers would be the simplest possible
expression of a fundamental building block that is responsible for
time -- although the time we experience is a much more complex
phenomena.

It makes sense to me that time is strongly related to recursivity
(maybe because of a CS background). I imagine moments being "copied
forward" and changed in some fashion.

Would you agree with these intuitions?
