Turing machine

A Turing machine is an abstract machine that manipulates symbols on a strip of tape according to a table of rules; to be more exact, it is a mathematical model of computation that defines such a device. Despite the model's simplicity, given any computer algorithm, a Turing machine can be constructed that is capable of simulating that algorithm's logic.

The machine operates on an infinite memory tape divided into cells. The machine positions its head over a cell and "reads" (scans) the symbol there. Then per the symbol and its present place in a finite table of user-specified instructions the machine (i) writes a symbol (e.g. a digit or a letter from a finite alphabet) in the cell (some models allowing symbol erasure and/or no writing), then (ii) either moves the tape one cell left or right (some models allow no motion, some models move the head), then (iii) (as determined by the observed symbol and the machine's place in the table) either proceeds to a subsequent instruction or halts the computation.

The Turing machine was invented in 1936 by Alan Turing, who called it an a-machine (automatic machine). With this model Turing was able to answer two questions in the negative: (1) Does a machine exist that can determine whether any arbitrary machine on its tape is "circular" (e.g. freezes, or fails to continue its computational task); similarly, (2) does a machine exist that can determine whether any arbitrary machine on its tape ever prints a given symbol. Thus by providing a mathematical description of a very simple device capable of arbitrary computations, he was able to prove properties of computation in general - and in particular, the un computability of the Hilbert Entscheidungsproblem ("decision problem").

Thus, Turing machines prove fundamental limitations on the power of mechanical computation. While they can express arbitrary computations, their minimalistic design makes them unsuitable for computation in practice: real-world computers are based on different designs that, unlike Turing machines, use random-access memory.

Turing completeness is the ability for a system of instructions to simulate a Turing machine. A programming language that is Turing complete is theoretically capable of expressing all tasks accomplishable by computers; nearly all programming languages are Turing complete.

Turing Machine (band)

Turing Machine is an instrumental rock band formed in New York City in 1998 by Justin Chearno and Scott DeSimon, late of DC's noise-rockers Pitchblende and Gerhardt 'Jerry' Fuchs, who had moved to New York to play with Bitch Magnet guitarist Jon Fine's new band, Vineland. Their music has been described as "Angular instrumental indie rock," that has "influences as vast as vintage prog, Krautrock and post-punk."

On November 7, 2009, drummer Fuchs died in an elevator shaft accident. The last of Fuchs' studio work with Turing Machine was included posthumously in the 2012 album, What Is The Meaning of What. Some of the friends of the band such as Pat Mahoney of LCD Soundsystem and Brian Chase helped to complete the unfinished album after Fuchs' death.

The name comes from the hypothetical device defined by Alan Turing with the same name.
