I defined "computation" above as Turing-computation. It's the only useful & rigorous definition I know of.
What does the equality of computation & physics even mean? What is physics? To me, physics consists of a number of large scale models of the world that remain incomplete. Also: if you consider the possibility of radical emergence (new rules coming into play at particular transitions in the history of the universe: eg nucleosynthesis, origin of life, and so on) then there is..

@kendmiller@qoto.org ... no closure to physics (it remains forever incomplete) & is therefore not formalizable in a way the term "computation" suggests. This is why I find any broad & vague application of the term misleading & restricting. By considering physics as computation, you limit yourself to the syntactic, symbolic realm (a small world where everything is well-defined), but the world we actually live in is full of ill-defined problems, ambiguity, & relevant cues are hard to come by.
