13. Art + Communication : WAVES 7 Wikipedia about Church Turing Thesis http//en.wikipedia. org/wiki/ChurchTuring_Thesis 8 I am sharing this current position to some degree having not http://rixc.lv/06/en/txt02.html

WAVES - an introduction The Genesis of the Idea The Art and Science of WAVES Based on this premise, making the WAVES exhibition and event happen is research into one half of what I consider the fundamentals or basics of contemporary practice in art and technology. Waves are literally the medium of media art, on the deepest material level as well as conceptually. Electromagnetic waves occur naturally, they exist, they are everywhere, constantly passing through our bodies, yet with our natural senses we can only perceive heat and light. "what is thought of as "light" is actually a propagating oscillatory disturbance in the electromagnetic field, i.e., an electromagnetic wave. Different frequencies of oscillation give rise to the different forms of electromagnetic radiation, from radio waves at the lowest frequencies, to visible light at intermediate frequencies, to gamma rays at the highest frequencies." Wikipedia It can surely be no coincidence that this iconoclastic artistic "statement" entered the debate about the nature of the world just as the revolutions in linguistics, physics, psychology and commerce were exploding the rationalist certainties of the 19th century. Robert Adrian 1996 This new situation has been preceded by Gaston Bachelards writing on the Formation of the Scientific Spirit (1934) where he reflected on the consequences of the paradigm change initiated by Einstein, Heisenberg and Bohr. The new scientific worldview is capable of incredible and horrific things, such as taming the atom or unleashing the atomic force in the shape of nuclear explosions. Yet in explaining wave/particle dualism science has still nothing much better to offer than the Copenhagen Interpretation.

Physics Help and Math Help - Physics Forums PF Lounge General Discussion Philosophy ... PDA View Full Version : Is Mathematics Discovered or invented? ComputerGeek It is classic, but I would like to know what you all think. invented. but its not as invented as chemistry - damn thats made up! (yes i am a student) selfAdjoint It is classic, but I would like to know what you all think. I b3elieve it's invented, but it FEELS like discovery. And I believe this is so (I have posted this before) because mathematical ideas are by definition WELL-DEFINED. That is they each have a limited and explicit definition agreed on by all, which gives them a sharp-edged character, just like our sensations of a rock or a chair in our environment. So the mind treats them that way and they feel like discoveries. Pengwuino I feel it is a discovery because any invention can be modified to do anything. We don't invent F=ma for example, we discover it... or else we would be perfectly capable of saying F=2ma. Who would be to say we're wrong if its just an invention? Inventions are never "wrong", some are just better then others. Rade I agree with Ayn Rand on this point..."a vast part of higher mathematics...is devoted to the task of discovering methods by which various shapes can be measured" (e.g., integral calculus used to measure area of circles as one example). In this way, the mental process of "concept formation" and "applied mathematics" have a similar goalidentfying relationships to perceptual data.

Bad Astronomy and Universe Today Forum Space and Astronomy General Science PDA View Full Version : Odd computing question ASEI 09-June-2007, 03:51 PM I've read statements before about non-Turing-machines being able to solve problems that Turing machines (pretty much encompassing all computers we know of) cannot. But I'm having a hard time understanding what is meant by a non-turing machine: Wouldn't it be possible to simulate any sort of computer on a computer using some sort of state-variable simulation? (Doesn't matter if it's arbitrarily complex). It always seemed to me that computers were general in this way. 09-June-2007, 05:44 PM Wouldn't it be possible to simulate any sort of computer on a computer using some sort of state-variable simulation?

This paper investigated mathematical systems in which an oracle was available, which could compute a single arbitrary (non-recursive) function from naturals to naturals. He used this device to prove that even in those more powerful systems, undecidability is present. Turing's writing made it clear that oracle machines were only mathematical abstractions, and were not thought of as physically realisable.

Realistic Benefits of Quantum Computing, by the end of year 2008 (techdo.com) 1 point posted 3 months ago by 6 comments info comments related details [deleted] (0 children) [+] [deleted] 3 points 3 months ago The article seems way over-hyped for my tastes, but interesting stuff nonetheless permalink tomashark (5 children) [+] tomashark 1 point 3 months ago Flaming BS. permalink (4 children) [+] 1 point 3 months ago Sorry? permalink parent tomashark (3 children) [+] ... tomashark 1 point 3 months ago The article makes numerous blatantly false claims. It generally misleads the audience into thinking that quantum computing is much more powerful than current science understands it to be. It's a joke: Unlike bits, qubits can represent more than one number at a time, One isolated qubit can store no more than one classical bit of information. That its state can take on a continuum of values is, for storing bits, no more different than saying a weighted coin can take on a continuum of head/tail probabilities p in [0,1]. Quantum computing is very subtle - a lot of things which look quantum are actually also found in classical probabilistic computers.

The source document, which specifies a Turing machine , is an XML document that conforms to the Turing Machine Markup Language (TMML). The input tape for the Turing machine is "199". http://www.unidex.com/turing/utm.htm (914 words) Tools for Thought by Howard Rheingold: Chapter One Turing proved that his hypothetical machine is an automated version of a formal system specified by the starting position (the pattern of Os and Xs on the tape at the beginning of the computation ) and the rules (the instructions given by the instruction tables). Turing 's theoretical machine was both an example of his theory of computation and a proof that a certain kind of computing machine could, in fact, be constructed.

IIDB IIDB Philosophical Forums Philosophy PDA View Full Version : Essay on CRA, advice appreciated. Jneale February 2, 2005, 05:48 PM John Searle and the Chinese Room: A Defence of Turing and Behaviourism We are entering or indeed are already upon one of the most exciting periods of epistemic history. Epistemology concerns issues that were always considered to be suited to the realm of philosophy, essentially that the concepts it discussed were too abstract in their nature to be considered science. Today these issues are no longer involved in purely philosophical debate but in cognitive science and its derivatives also. I shall refer to the mind as if I was advocating substance dualism, normally associated as part of Descartes meditations; however I don’t wish to enter into a debate over monism, dualism, as it really has no effect on the issues I want to deal with. Every psychological attribute has now, due to considerable recent advances in neuro-anatomical science, been associated with a specific location in the brain. The ability to assimilate visual input with the occipital lobe, the process of sorting objects into categories with the temporal lobe, Intentionality with the parietal lobe and reasoning with the frontal lobe. Even semantics have been associated with activity in parts of the brain. Semantics is a frequently used term in cognitive science and it is important for me to clarify what I intend by the term. Language has two levels, syntax and semantics. Syntax is the sound, series of letters the symbol I use to represent the semantics behind language. When I read this essay you hear the symbols, syntax, and interpret its semantic meaning, when you ask questions at the end you will do so through syntax and I shall be interpreting with semantics. Despite this relationship being made slightly more complex by the presence of an internal monologue the concept remains the same.

Information Delight Church-turing Thesis The Thesis claims that any calculation that is possible can be performed by an Algorithm running on a computer, provided that sufficient time and storage space are available. It is generally assumed that an algorithm must satisfy the following requirements: #The algorithm consists of a finite set of simple and precise instructions that are described with a finite number of symbols. #The algorithm will always produce the result in a finite number of steps. #The algorithm can in principle be carried out by a human being with only paper and pencil. #The execution of the algorithm requires no intelligence of the human being except that which is needed to understand and execute the instructions. The Euclidean Algorithm for determining the Greatest Common Divisor of two Natural Number s is an example of such an algorithm. This description of algorithm is intuitively clear but lacks formal rigor, since it is not exactly clear what a "simple and precise instruction" is, and what exactly the "required intelligence to execute these instructions" is. (See, for example, Effective Results In Number Theory for cases well beyond the Euclidean algorithm.)

[Proginoskes] [Eric Gisse] Why is the number of algorithms countable as opposed to uncountable? Yes, I know the difference between 'countable' and 'uncountable'. It's for the same reason that the set of all possible books in any given human language is countable: the set of all finite strings composed of symbols from a finite alphabet is countable. An algorithm has to be /specified/ somehow, right? Whether you pick English or a formalism like Turing machines, all possible finite strings from the alphabet you pick are countable. If you allow algorithm specifications of infinite length, you can worm around that but then few would agree that you're still talking about what /they/ mean by "algorithms".

This is why computing is a real, separate discipline, and why it's so hard to get those from other disciplines to believe that it is. permalink diamond (1 child) [+] diamond 40 points 3 months ago Yes it will. permalink wazzadoin (0 children) [+] ... wazzadoin 7 points 3 months ago You are smart.

Home Article Index Church-Turing thesis The Church-Turing thesis is an idea in computer science named after the mathematicians Alonzo Church and Alan Turing . In its most common form, it states that every effective computation or algorithm can be carried out by a Turing machine . Any computer program in any of the conventional programming languages can be translated into a Turing machine, and any Turing machine can be translated into most programming languages, so the thesis is equivalent to saying that the conventional programming languages are sufficient to express any algorithm. The thesis, which is now generally assumed to be true, is also known as Church's thesis or Church's conjecture and Turing's thesis Table of contents 1 Equivalent forms of the thesis 2 Origins of the thesis 3 Success of the thesis 4 Philosophical implications ... 7 See also Equivalent forms of the thesis The thesis might be rephrased as saying that the notion of effective or mechanical method in logic and mathematics is captured by Turing machines. It is generally assumed that such methods must satisfy the following requirements: The method consists of a finite set of simple and precise instructions that are described with a finite number of symbols.
