It's you who's begging the question, first define what is a
computation with physics first, without relying on abstract
mathematical notion.
A computation with physics is what is happening in the computer I am
currently working on. I can describe this in mathematical notation if
you wish, but the process is not the notation. Any process that takes
input and produces output is a computation. All physical objects do
this. And physical objects do not know any mathematics.

But that does not prove that the computation does not run on
a physical computer. I take JC's point to be that your
assumption of the primacy of the abstract computation is
unprovable. We at least have experience of physical
computers, and not of non-physical computers. (Whatever you
say to the contrary,
You're making an ontological commitment and closing any
discussion on it...
All I am asking for is a demonstration of the contradiction that
you all claim exists between computationalism and physicalism -- a
contradiction that does not simply depend on a definition of
computationalism that explicitly states "physicalism is false". In
other words, where is the contradiction? A demonstration that
does not just beg the question.
