Webbquence, any physically realizable super-Turing machine must be non-deterministic. Turing proposed this idea when discussing how to make a machine behave like a brain by making "its behavior depend on something like a roulette wheel or a supply of radium" [7].

A function is considered to be computable if and only if it is computable on Turing’s model of computation. Since our notion of computable is informal and Turing’s model gives a precise definition of computable, we cannot prove the two equivalent.
