Mathematicians. If you let them use the concept of infinity, there’s almost nothing they won’t be able to prove. Case in point: the Turing machine. The idea is that with an infinite length of tape, ...

A mathematical model of computation. Named after English scientist Alan Turing, a Turing machine is a finite state machine that reads a tape divided into cells. The Turing machine examines the symbol ...

Alan Turing's simple thought experiment, a human in a box following a book of instructions, redefined what it means to think ...

Alan Turing was one of the most influential British figures of the 20th century. In 1936, Turing invented the computer as part of his attempt to solve a fiendish puzzle known as the ...

Turing machines are widely believed to be universal, in the sense that any computation done by any system can also be done by a Turing machine. In a new article, researchers present their work ...
