This result has since become known as Church’s Theorem or the Church-Turing Theorem (which should not be confused with Church’s Thesis, also known as the Church-Turing Thesis2). WebThe Church-Turing Thesis is that anything that we can reasonably call calculation can be performed on a Turing machine (or in lambda calculus, or anything equivalent). Since nobody's come up with an exception, it's pretty generally accepted, but it's obviously impossible to prove. – David Thornley Sep 23, 2010 at 19:52 2
