Extractions: Version for printing Alan Turing was born at Paddington, London. His father, Julius Mathison Turing, was a British member of the Indian Civil Service and he was often abroad. Alan's mother, Ethel Sara Stoney, was the daughter of the chief engineer of the Madras railways and Alan's parents had met and married in India. When Alan was about one year old his mother rejoined her husband in India, leaving Alan in England with friends of the family. Alan was sent to school but did not seem to be obtaining any benefit so he was removed from the school after a few months. Next he was sent to Hazlehurst Preparatory School where he seemed to be an 'average to good' pupil in most subjects but was greatly taken up with following his own ideas. He became interested in chess while at this school and he also joined the debating society. He completed his Common Entrance Examination in 1926 and then went to Sherborne School. Now 1926 was the year of the general strike and when the strike was in progress Turing cycled 60 miles to the school from his home, not too demanding a task for Turing who later was to become a fine athlete of almost Olympic standard. He found it very difficult to fit into what was expected at this public school, yet his mother had been so determined that he should have a public school education. Many of the most original thinkers have found conventional schooling an almost incomprehensible process and this seems to have been the case for Turing. His genius drove him in his own directions rather than those required by his teachers.

Extractions: This person built a Turing Machine out of Lego, and has posted extensive build-notes. Well, this Turing machine is not entirely mechanical... I used the RCX to store the transition table. Since the symbols are bar codes read with a light detector, it would have been very difficult to continue with a physical mechanism. Three subroutines are required, one to select which symbol to provide on top of the memory, one to turn the provider one quarter of a turn, and one to pull out one symbol from the bottom of the memory (reading it on the way).

Extractions: The Failings of Functionalism and Related Theses February, 2002 Submitted to JETAI Chris Eliasmith Dept. of Philosophy University of Waterloo eliasmith@uwaterloo.ca The properties of Turings famous universal machine has long sustained functionalist intuitions about the nature of cognition. Here, I show that there is a logical problem with standard functionalist arguments for multiple realizability. These arguments rely essentially on Turings powerful insights regarding computation. In addressing a possible reply to this criticism, I further argue that functionalism is not a useful approach for understanding what it is to have a mind. In particular, I show that the difficulties involved in distinguishing implementation from function make multiple realizability claims untestable and uninformative. As a result, I conclude that the role of Turing machines in philosophy of mind needs to be reconsidered. The Myth of the Turing Machine

http://www.daviddarling.info/encyclopedia/T/Turing_machine.html

Extractions: An abstract model of computer execution and storage introduced in 1936 by Alan Turing to give a mathematically precise definition of algorithm . A Turing machine can be thought of as a black box that carries out a calculation of some kind on an input number. If the calculation reaches a conclusion, or halts, then an output number is returned. Otherwise, the machine theoretically carries on forever. There are an infinite number of Turing machines, as there are an infinite number of calculations that can be done with a finite list of rules. A Turing machine that can simulate any other Turing machine is called a universal Turing machine . The concept of Turing machines is still widely used in theoretical computer science, especially in complexity theory and the theory of computation.

These texts need not be in a traditional literary form, although for the purposes of this discussion they will be assumed to be in a common style familiar to a human reader, such as a monologue, poem, letter, short story etc. The machine itself need not be a computer although as with many large and complicated problems of the past century, the computer is currently the only machine capable of manipulating the rules and components of language in anything approaching the complexity used by human writer.

Extractions: Turing machine Cool LEGO creation. Although it is composed of pretty simple capabilities, Turing argued that this simple machine could performed any computation, that is, could realize anything that results from operations. In 1950, he discussed that the mind is itself the results of operations (at the neural level) and thus is the creator of the artificial intelligence studies.

A Turing machine is conceived to be a box with a tape and a tape head. The tape consists of an infinite number of cells stretching in both directions, with the tape head always located over exactly one of these cells. Each cell has symbol from written on it. At the beginning of its computation, is in state and a finite string (the input string) over the alphabet is written on the tape, with the tape located over the first letter of

http://arxiv.org/abs/math.LO/0209332

Extractions: Due to common misconceptions about the Church-Turing thesis, it has been widely assumed that the Turing machine provides an upper bound on what is computable. This is not so. The new field of hypercomputation studies models of computation that can compute more than the Turing machine and addresses their implications. In this report, I survey much of the work that has been done on hypercomputation, explaining how such non-classical models fit into the classical theory of computation and comparing their relative powers. I also examine the physical requirements for such machines to be constructible and the kinds of hypercomputation that may be possible within the universe. Finally, I show how the possibility of hypercomputation weakens the impact of Godel's Incompleteness Theorem and Chaitin's discovery of 'randomness' within arithmetic.

Extractions: Introduction to Computing Science An algorithm is a computational process that takes a problem instance and in a finite amount of time produces a solution. . . . It is hard to make the definition of algorithm more precise except by saying that a computational process is anything that can be done by a program for a computing machine, and in that case one must accept that a human being with paper and pencil is a kind of computing machine. (Floyd and Beigel, The Language of Machines , Computer Science Press, W.H. Freeman, 1994, p. 444.) Problems which are intended to be solved by a computational process may be stated in a variety of ways: Decision Problems A decision problem is stated as a question with a "yes" or "no" answer, such as: If the problem is stated as a Boolean statement - an assertion which is either true or false - we call the statement a predicate If there is an effective procedure for answering the question or evaluating the assertion, we say that the problem is

Extractions: Turing Machine Markup Language (TMML). Robert C. Lyons of Unidex Inc. has created an XML-based Turing Machine Markup Language (TMML) for describing Turing machines. "Just for fun," he says in the XML-DEV announcement... "I created TMML and the Universal Turing Machine stylesheet to have some fun and to learn more about the XSLT language; I designed this site to share what I learned about Turing machines and XSLT. A language is Turing complete if it is powerful enough to implement any Turing machine. It is widely believed that Turing machines are powerful enough to perform any calculation that can be performed by a modern computer program." Lyons' TMML web site "provides sample TMML documents and an XSLT 1.0 stylesheet that interprets ( i.e. , executes) the Turing machine that is described in a TMML document. This XSLT stylesheet, which is a Universal Turning Machine, is an existence proof that XSLT 1.0 is Turing complete. The stylesheet, which is available in HTML format and as an XSLT document, has been run with SAXON and Xalan. It does not use any extension functions or proprietary features. The stylesheet does use the xsl:key instruction and the XPath function."
