WebThe difference between the Church-Turing thesis and real theorems is that it seems impossible to formalize the Church-Turing thesis. Any such formalization would need to formalize what an arbitrary computable function is, which requires a model of computation to begin with.

This was done by Alonzo Church in 1935 with the concept of "effective calculability" based on his λ-calculus, and by Alan Turing the next year with his concept of Turing machines. Turing immediately recognized that these are equivalent models of computation.
