But if you know how to make a computation without a physical device then do so; and I look forward to reading about you in the Wall Street Journal about how you became the world's first trillionaire by starting a computer hardware business with zero production costs. >>> Church's thesis is not related to physics at all > > >> I see.

From Wolfram Mathworld, the makers of Mathematica: "The Church-Turing thesis (formerly commonly known simply as Church's thesis) says that any real-world computation can be translated into an equivalent computation involving a Turing machine. In Church's original formulation (Church 1935, 1936), the thesis says that real-world calculation can be done using the lambda calculus, which is equivalent to using general recursive functions." > >> As I said, Bruno Marchal is not an expert on logic. > > > > Ah, it is you, the guy who stop at step 3.
