Church's thesis

Church's thesis, also known as the Church-Turing thesis, suggests that any function or problem that can be effectively computed or solved by an algorithm can be performed by a Turing machine, a theoretical model of computation. In simpler terms, it proposes that the set of problems solvable by any means of effective calculation is exactly those that can be addressed by a standard, well-defined step-by-step procedure. This idea helps define the limits of what computers and algorithms can achieve, establishing a foundational understanding of computation's capabilities and boundaries.
