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 ...

This week we’ll venture in the realm of theory for a change, starting with Turing machines. In case some of you don’t know what a Turing machine is, here is the Wikipedia definition: “A theoretical ...

The goal of the “busy beaver” game is to find the longest-running computer program. Its pursuit has surprising connections to some of the most profound questions and concepts in mathematics.

On June 23, we commemorate the birth of Alan Mathison Turing, a visionary whose profound contributions laid the very groundwork for modern computing and artificial intelligence. Often hailed as the ...

Everything about this Turing machine is absolutely brilliant. A Turing machine uses a strip of material to record, calculate, and change data. [Mike Davey] built this one using servo motors, a ...
