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 mechanically. This video traces how that insight set the boundaries of what ...

It is the height of the Second World War. A group of codebreakers stands in a dimly lit warehouse 50 miles northwest of London, a giant machine composed of spinning drums and wires looms in front of ...

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 ...
