El Angulo de Devlin Marzo de 2001 Claude Shannon El matemático Claude Shannon murió el Sábado 22 de Febrero, a los 84 años de edad, luego de una larga lucha contra el mal de Alzheimer. Pero su legado intelectual perdurará mientras la gente se comunique usando el teléfono y el fax, la Internet, o simplemente hablando de "información" como un recurso que puede ser medido en "bits" y enviado de lugar en lugar. Sigue aún vigente el enfoque de la información y la comunicación que Shannon estableció en su revolucionario trabajo "A Mathematical Theory of Communication" (Una Teoría Matemática de la Comunicación) publicado en el Bell System Technical Journal (Revista Técnica de los Sistemas Bell) en 1948, y vuelto a publicar virtualmente exacto en el panfleto "The Mathematical Theory of Communication" (La Teoría Matemática de la Comunicación), que escribió junto a Warren Weaver el año siguiente (publicado por la Universidad de Illinois). (Observe el cambio de artículo -"La" por "Una"- de la versión Shannon-Weaver). Shannon nació en Michigan en 1916. Luego de obtener títulos en Matemáticas e Ingeniería en la Universidad de Michigan, ingreso al MIT (Massachussets Institute of Technology) para continuar estudios de postgrado en Matemáticas. Aqui hizo contacto con muchos de los hombres que estaban creando las bases para revolución de la información que explotaría a finales de la Segunda Guerra Mundial, en especial, con el matemático Norbert Wiener (quien más adelante acuñaría el término "cibernética" para parte del trabajo que el mismo, Shannon y otros en el MIT y otras partes), y Vannevar Bush, el decano de Ingeniería en el MIT (cuya máquina conceptual "Memex" prefiguró la moderna World Wide Web y entre cuyos logros subsecuentes se incluye el establecimiento de la "National Science Fundation" -Fundación Nacional de la Ciencia-).

Supplementary: toc ... to restore theology to the mainstream of science Claude Shannon Shannon founded the mathematical theory which underlies the current revolution in communication. He first defined information, and then showed how to transmit information fautlessly over a noisy channel by suitable encoding. The requirements for a good code have guided the search for codes ever since, and we can see that communication in the natural world is governed by the same model. Information is defined as 'that which removes uncertainty'. The measure of an item of information is the amount of uncertainty it removes. Shannon chose entropy as his measure of uncertainty. Entropy had entered physics through the thermodynamics of heat engines. In thermodynamics it serves as a measure of disorder, complexity, or the quality of energy. The second law of thermodynamics tells us that entropy does not decrease. The mathematical expression of entropy goes beyond its physical origins. We now see it as a measure of the size of a space. The information necessary to specify a point in any space is equal to the entropy of the space. So, if we think of the english language as a space of, say, one million words, we may say that the entropy of english is one million per word, and the transmision of one english word conveys one million units of information.

Home Page Informática Criptologia História ... RALA CUCA CLAUDE ELWOOD SHANNON Claude Elwood Shannon A capacidade de transmitir digitalmente a voz, as imagens e os dados usando bits e bytes e enviando-os através de linhas telefônicas, cabos, satélites e da Internet, deve-se a um gênio criador que, há pouco mais de 50 anos, lançou as bases de uma teoria matemática da comunicação. Em 1948, Claude Elwood Shannon conseguiu um feito raramente repetido na história da ciência: com um trabalho intitulado Uma Teoria Matemática da Comunicação , publicado na revista Bell System Technical Journal , abriu uma área nova e inédita na matemática. Esta área surgiu essencialmente completa, com as definições e conceitos básicos formulados, com os teoremas e resultados fundamentais já estabelecidos e, o mais espantoso, sem precedentes visíveis na literatura existente na época. Raras vezes isso acontece, pois os avanços da ciência, mesmo que geniais, podem habitualmente se referir a problemas há muito discutidos, a teorias em gestação e a descobertas precedentes. O próprio Newton, ao criar a física moderna, disse ter podido ver mais longe por ter-se alçado aos ombros de gigantes. Referia-se assim às descobertas e aos trabalhos de Copérnico, Galileu, Kepler e outros. O trabalho que Shannon publicado em 1948 apareceu de forma totalmente inesperada e veio a ter um alcance que os seus contemporâneos, e talvez até o próprio Shannon, não conseguiram vislumbrar naquele momento. Foi um dos raros passos decisivos, inesperados e globais que até hoje se registaram na história da ciência.

Class Bios of Claude Shannon Bio 1... by Julie Chen: Introduction Humble beginnings Education Theoretical contributions Information source Transmitter Signal + Received signal Receiver Destination (message sent) (message received) Furthermore, Shannon developed an explanatory concept of balancing entropy and redundancy to achieve efficiency in the communication process. This would be the other half of his climactic achievements. The concept of entropy, as noise in a channel, and its effect on communications aided the understanding of and the progress towards improving information transmission. Basically, the increase in noise causes a greater need for redundancy, which reduces the relative entropy of the message. However, redundancy in turn reduces the amount of information that can be transmitted in a given time. The idea, then, is to somehow balance the two antagonizing elements to achieve utmost efficiency from the total system. Here is my non-scientific analogy: Compare the communication system mentioned above to the classroom setting, perhaps J363 at the University. The more conversational dialogue (

Search MAA Online MAA Home Devlin's Angle March 2001 Claude Shannon Mathematician Claude Shannon died on Saturday February 22, aged 84, after a long struggle with Alzheimer's disease. But his intellectual legacy will live on as long as people communicate using phone and fax, log on to the Internet, or simply talk about "information" as a commodity that can be measured in "bits" and shipped from place to place. The approach to information and communication Shannon laid out in his groundbreaking paper "A Mathematical Theory of Communication," published in the Bell System Technical Journal in 1948, and republished virtually unchanged in the pamphlet The Mathematical Theory of Communication he wrote with Warren Weaver the following year (published by the University of Illinois Press) remain current to this day. (Note how the "a" of his paper became "the" in the Shannon-Weaver version.) Shannon was born in Michigan in 1916. After obtaining degrees in both mathematics and engineering at the University of Michigan, he went to MIT to pursue graduate studies in mathematics. There he came into contact with some of the men who were laying much of the groundwork for the information revolution that would take off after the Second World War, notably the mathematician Norbert Wiener (who later coined the term cybernetics for some of the work in information theory that he, Shannon, and others did at MIT and elsewhere) and Vannevar Bush, the dean of engineering at MIT (whose conceptual "Memex" machine foretold the modern World Wide Web and whose subsequent achievements included the establishment of the National Science Foundation).

hi-res full release Claude Shannon produced one of the great conceptual breakthroughs of his generation with the publication of his seminal work, A Mathematical Theory of Communication. It laid the foundations of information theory, explaining that binary digits - which he first called ``bits'' - could carry information in a digital form. This radical idea led directly to the wide range of digital inventions so common today, from cell phones and CDs to cameras and computers. By showing how information could be manipulated in a precise, mathematical way, he gave engineers what experts have called ``a blueprint for the digital age.'' Shannon was born in Gaylord, Michigan. He earned his B.S. degree from the University of Michigan in 1936; he then went on to MIT, where he received an M.S. in electrical engineering and a Ph.D. in mathematics. While at MIT, he worked under Vannevar Bush on the differential analyzer, an early analog device that was the most powerful computer of its day, but ultimately made obsolete by the more powerful digital devices envisioned by Shannon. He was the recipient of many honors, including the Institute of Electrical and Electronics Engineers Medal of Honor, the Kyoto Prize and the National Medal of Science.

73. Shannon-Weaver Model claude shannon and Warren Weaver produced a general model of communication This is now known after them as the shannonWeaver Model. http://www.cultsock.ndirect.co.uk/MUHome/cshtml/introductory/sw.html

The Shannon-Weaver Model Please note: The Shannon-Weaver model is typical of what are often referred to as transmission models of communication. For criticisms of such models, you should consult the section on criticisms of transmission models If you have looked through the examples of typical everyday forms of communication , you will have noticed that some of the examples refer to less immediate methods of communication than face-to-face interaction, e.g. using the radio, newspapers or the telephone. In these cases, technology is introduced. When, for instance, the telephone is used, you speak, the phone turns the sound waves into electrical impulses and those electrical impulses are turned back into sound waves by the phone at the other end of the line. Claude Shannon and Warren Weaver produced a general model of communication This is now known after them as the Shannon-Weaver Model. Although they were principally concerned with communication technology The Shannon-Weaver Model (1947) proposes that all communication must include six elements: a source an encoder a message a channel a decoder a receiver These six elements are shown graphically in the model. As Shannon was researching in the field of information theory, his model was initially very technology-oriented. The model was produced in 1949, a year after Lasswell's and you will immediately see the similarity to the

Claude Elwood Shannon April 30, 1916 - February 24, 2001 Claude Elwood Shannon was born in Petoskey, Michigan, on April 30, 1916. He graduated with a B.S. in mathematics and electrical engineering from the University of Michigan in 1936. Shannon earned both a master's degree and a doctorate in 1940 as a student of Vannevar Bush at the Massachusetts Institute of Technology. At that time Vannevar Bush was vice president of M.I.T. and dean of the engineering school, and actively conducting research on his invention the differential analyzer, the first reliable analog computer that solved differential equations. Shannon's electrical engineering master's thesis "A Symbolic Analysis of Relay and Switching Circuits" has been described as one of the most important master's theses ever written. In it Shannon applied George Boole's binary (true-false) logic algebra found in Russell and Whitehead's Principia Mathematica to the problem of electronic (on-off) switching circuits. At the time, Boolean arithmetic was little known or used outside the field of mathematical logic. Because of Shannon's work, Boolean arithmetic is the basis for the design and operation of every computer in the world. For his Ph.D. dissertation in mathematics, Shannon applied mathematics to genetics. This work was influenced by Norbert Wiener, one of his coworkers with Vannevar Bush at MIT. Wiener studied how the nervous system and machines perform the functions of communication and control, and as acknowledged by Shannon, Wiener made some early contributions to the field of information theory.

Shannon Claude Elwood Shannon , Donner Professor of Science at the Massachusetts Institute of Technology, has, in a long and celebrated career, developed the mathematical theories and techniques that make possible the analysis of switching circuits, computers and communications. His most significant piece of work is "A Mathematical Theory of Communication," published in two parts in the Bell System Technical Journal in 1947-48. With this paper, Shannon laid down the theoretical foundation for communications engineering-a kind of "thermodynamics of communications" which, up to that time had been missing. In opening a new mathematical field for engineering applications, Shannon's work compares only to that of Norbert Wiener in the theory of time series and to that of Von Neumann and Morgenstern in the theory of games. Of equal importance has been the impact of Shannon's definitions, his model of the communications process and his theory on scientists and engineers concerned with human communications. In particular, Shannon's measure of information has found wide use in experimental psychology.
