I cannot explain what "hurluberlu" means, except that it means
crackpot. Sort of total fantasy ...

Math is math, but is physic math? By a concrete UD I was meaning a real
actual one, like the one I have implemented on a macintosh SE/30, and
which
has been running during two weeks in 1990 at Brussels.

Of course I postulate here some "physical universe" as a local decor.

Look, to be sure we are using "impIementation" in the same sense, I quote
yourself (from http://hammer.prohosting.com/~mathmind/cwia.htm#II3)
<<In turn, a computation is
associated with a physical system only if it has been implemented
by that system. Implementation is usually taken to mean that there is
some direct correspondence between the formal states of that computation,
and the states of the physical system, which can be described
mathematically.>>

So either you believe there is only math (including computer science and
all computations), then "implementation" is a emerging concept, as are
anything linked to physical predicates.
Or you believe there exists something "physical" per se. Then indeed
you can defined implementation in a sense relative to that physicalness.
In either case you need to define it. And you *know* in either case it is
a problem: mine and your's.

Actuality is a first person concept. 3rd person view is everything
you can communicate in a scientific manner without taking into account
the subjective view of a person.

You are not the only one. It's part of the game.

Crap means "merde" according to my dictionnary. Is it true "crap" means
"shit"?
You know "merde", isn't it?, The famous word used by the general Cambrone
during the Napoleonian wars ...
