A Turing machine is a mathematical model of computation describing an abstract machine that manipulates symbols on a strip of tape according to a table of rules. Despite the model's simplicity, it is
A physical Turing machine model constructed by Mike Davey. A true Turing machine would need to be provided more memory (tape) if and when required; physical models can only have a finite amount.

…computer program, it is possible for a Turing machine to go into an infinite loop which will never halt. The Turing machine was invented in 1936 by Alan Turing, who called it an "a-machine" (automatic machine). It was Turing's doctoral advisor, Alonzo Church, who later coined the term "Turing machine" in a…
