[sdiy] Is everything digital?

[xmurz at gmx.de]

maybe some interesting further reading:

"Simulating Physics" by Richard P.Feynman 1981
"Quantum Theory, the Church-Turing principle and the universal quantum computer" by D. Deutsch 1984

I have both articles here (scanned in and as a copy).

As some have pointed out, "analogue" and "digital" are only "models" which
are simplifications which are true only to a certain extend (a certain "space").
Nothing truely "is"  analogue or "digital". 
We use models such as quantum theory to describe what we otherwise don't 
know how to talk about in a scientific manner.

But all models we have are only models. Even mathematics.
We can prove things but we use models again. 
The only real judge is nature. But even nature can be inconsistent.

When I got to know quantum computing / quantum theory, I thought
now we finally get a system where we can't say "digital" or "analogue" anymore,
we can end that digital vs analogue war :)
