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 WebSep 9, 2004 · Alan Turing was one of the most influential thinkers of the 20th century. In 1935, aged 22, he developed the mathematical theory upon which all subsequent stored-program digital computers are modeled. At the outbreak of hostilities with Germany in September 1939, he joined the Government Codebreaking team at Bletchley Park, …

Notoriously, quantum computation shatters complexity theory, but is innocuous to … In computability theory, the Church–Turing thesis (also known as computability thesis, the Turing–Church thesis, the Church–Turing conjecture, Church's thesis, Church's conjecture, and Turing's thesis) is a thesis about the nature of computable functions. It states that a function on the natural numbers can be calculated by an effective method if and only if it is computable by a Turing machine. The thesis is named after American mathematician Alonzo Church and the British math… shutter tv show
