The Church-Turing Thesis Explained: What it is, and When it Was Formed

In simple terms, the Church-Turing Thesis, formerly known as “Church’s Thesis,” states that any computable function performed on natural numbers can be calculated by an effective method if, and only if, a Turing machine can perform the function.

The Church-Turing Thesis: Exact Definition

The Church-Turing Thesis states that a computational method can only be considered effective if a Turing machine can complete it.

How Does the Church-Turing Thesis Work?

– The method terminates (finishes) after a finite number of steps. – The method always produces a correct answer. – In principle, the solution must be achievable using nothing but writing materials. (This does not have to carry into practice).Description

The First Definition: Lambda Calculus

The history of the Church-Turing thesis takes us back to the 1930s. Then, when the most critical issue in theoretical mathematics was the potential introduction of a mechanical way of separating mathematical truths from mathematical falsehoods.
