TURING MACHINE - Essay Example In spite of its minimalism, a Turing machine could be modified to reproduce the logic of some computer algorithm, as well as this machine is mainly useful in illuminating the operations of a CPU within of a computer (Suber, 2002). This paper will present deep analysis of the different functionalities, operations, and uses of Turing machine. According to Weisstein (2009) the concept of the Turing machine was initially presented by Alan Turing in 1937. He also invented the initial Turing machine that was presented like an idealized model intended for mathematical computation. A Turing machine composed of a line of cells acknowledged as a "tape" that can be moved back as well as forth. In a Turing machine there is an active component "head" that has a feature acknowledged as "state" that is capable to transform the attribute recognized as "color" of the active cell below it, and also a set of commands for how the head needs to be adjusted by the active cell as well as shift the tape. In addition, the machine can transform the color of the Turing machine active cell at any step. Also, it can transform the position of the head, and moving the tape one step towards right or left (Weisstein, Turing Machine, 2009; Sipser, 2005). Copeland (2000), discusses about Universal Turing Machine (UTM), which is a Turing machine that is capable to replicate other Turing machine. An additional mathematically-oriented description by a related "universal" nature was presented by Alonzo Church, whose effort on lambda calculus linked with Turing in a prescribed hypothesis of computation identified as the Church–Turing theory. The theory presents that a Turing machines certainly holds the informal view of useful technique in mathematics as well as in logic, and also offers an accurate explanation of a mechanical procedure or algorithm (Copeland, 2000). According to Aanderaa (2006), a

An analysis and commentary - Essay Example The main cause for Scotland splitting ways with Britain is the unfair treatment they have regularly received from the queen, bankruptcy of the nation, and isolation. The number of Scottish people wanting independence in the last 40 years has sharply increased. 40 years ago, the number who proposed was only 25%. This number has risen lately according to recent polls conducted around Scotland to nearly half the electorate. These numbers can only predict that the Scottish people are craving to regain their identity, at least politically. If Scotland votes â€Å"yes,† this would affirm the need and the power of political identities. Scots will have a country of their own. In my opinion, Scotland separating from England will help to realize the identity of Scotland as a nation and seclude itself from the unfair treatment from England. This article is particularly relevant to political identity since the concerns of Scotland are primarily based on political identity.
