Using mathematics, computations and symbols; human embodied

observations of the physical universe and its processes.
This assumes that the actual observable physical universe is
exemplified by, and is, instantiations of, mathematics and
computations.
Why not assume that model is different from what is modeled?
That is usually the case. But this does not mean that it is always the
case. In particular digital "processes", or relations, can be emulated
exactly, so if you assume the brain is a natural computer, there are
possible "exact model", like a digital brain and its corresponding
relative state in arithmetic. From the 1p-view, those cannot be
distinguished in any immediate way.
If I simulate a typhoon on a computer in front of you, you will never
become wet by it. But if I read and cut you, and simulate with that
computer "you + the typhoon" at the right comp level (assuming it
exists) then you will, in that case, feel to be wet due to the
simulated typhoon. Likewise, the arithmetical typhoons can make wet
the relative arithmetical entities (with comp).

For example the impedance model of a Li-ion battery
http://www.unibw.de/eit8_2/forschung-en/projekte/battery/battery
is not the Li-ion battery. Even the Newman model of a Li-ion battery
http://www.cadfem.de/uploads/pics/EMobilitaet-01_w530.jpg
is not the Li-ion battery.
By the way, when you talk about a representation, you come to the
territory of semiotics (the world of signs)
http://plato.stanford.edu/entries/peirce-semiotics/
"What we see here is Peirce's basic claim that signs consist of
three interrelated parts: a sign, an object, and an interpretant."
From such a viewpoint, simulation as such represents nothing.

1) Does this mean that mathematics is *en-coded* as formulas in
matter and energy?
2) If so, are models, simulations, emulations, depictions,
replications, representations, a mathematical computational
*decoding* of an *en-coded* mathematical physical reality?
Thanks
