For years, links between entropy and information of a system have been proposed, but their changes in time and in their probabilistic structural states have not been proved in a robust model as a unique process.

Information Theory and its Applications to Fundamental Problems in Physics

Information theory is a branch of applied mathematics, electrical engineering, and computer science which originated primarily in the work of Claude Shannon and his colleagues in the s. It deals with concepts such as information, entropy, information transmission, data compression, coding, and related topics. Paired with simultaneous developments in cybernetics, and despite the criticism of many, it has been subject to wide-ranging interpretations and applications outside of mathematics and engineering. This page outlines a bibliographical genealogy of information theory in the United States, France, Soviet Union, and Germany in the s and s, followed by a selected bibliography on its impact across the sciences.

In information theory and statistics , negentropy is used as a measure of distance to normality. Buckminster Fuller tried to popularize this usage, but negentropy remains common. In a note to What is Life? It is the more familiar notion in this context. But this highly technical term seemed linguistically too near to energy for making the average reader alive to the contrast between the two things.

This is a very remarkable point of view, and it opens the way for some important generalizations of the notion of entropy. Wiener introduces a precise mathematical definition of this new negative entropy for a certain number of problems of communication, and discusses the question of time prediction: when we possess a certain number of data about the behavior of a system in the past, how much can we predict of the behavior of that system in the future? In addition to these brilliant considerations, Wiener definitely indicates the need for an extension of the notion of entropy. We certainly must be prepared to discuss the extension of entropy to scientific knowledge technical know-how, and all forms of intelligent thinking.

Negentropy (and entropy) in thermodynamics and information theory

By Leon Brillouin. In the first chapter it was shown that the measure of information as the amount of uncertainty which existed before a choice was made, was precise, but necessarily restrictive. Thus, for example, the Value of the information could not be included in such a measure. It was also shown that if unequal a priori probabilities existed for the possible choices, then these a priori probabilities may be interpreted as being constraints on our choice, the end result being a decrease in the amount of information. Thus, if the a priori probabilities are p 1, p2, …, pj , … for symbols 1 , 2 ,…, j , …, respectively, then the amount of information per symbol was shown to be [Eq. This equation was obtained, in effect, from the formula for information per symbol, when the choice had no constraints :. Thus, we used Eq.

За мгновение до того, как они сомкнулись, Сьюзан, потеряв равновесие, упала на пол за дверью. Коммандер, пытаясь приоткрыть дверь, прижал лицо вплотную к узенькой щелке. - Господи Боже мой, Сьюзан, с тобой все в порядке. Она встала на ноги и расправила платье. - Все обошлось.

Вскоре путь ей преградила кабина голосового сканирования, табличка на которой гласила: АГЕНТСТВО НАЦИОНАЛЬНОЙ БЕЗОПАСНОСТИ (АНБ) ОТДЕЛЕНИЕ КРИПТОГРАФИИ ТОЛЬКО ДЛЯ СОТРУДНИКОВ С ДОПУСКОМ Вооруженный охранник поднял голову: - Добрый день, мисс Флетчер. - Привет, Джон. - Не ожидал, что вы придете. - Да, я.  - Она наклонилась к микрофону и четко произнесла: - Сьюзан Флетчер. Компьютер немедленно распознал частоту ее голоса, и дверь, щелкнув, открылась. Сьюзан проследовала .

How is it possible to formulate a scientific theory of information? The first requirement is to start from a precise definition. Science begins when the meaning of the.

Беккер молча ждал выстрела, который должен оборвать его жизнь. ГЛАВА 89 Лучи утреннего солнца едва успели коснуться крыш Севильи и лабиринта узких улочек под. Колокола на башне Гиральда созывали людей на утреннюю мессу. Этой минуты ждали все жители города. Повсюду в старинных домах отворялись ворота, и люди целыми семьями выходили на улицы.

Эта светящаяся клавиатура управляла его личным лифтом. Стратмор и его высокопоставленные посетители попадали в шифровалку и уходили незаметно для остальных сотрудников. Лифт спускался на пятьдесят ярдов вниз и затем двигался вбок по укрепленному туннелю еще сто девять ярдов в подземное помещение основного комплекса агентства. Лифт, соединяющий шифровалку с основным зданием, получал питание из главного комплекса, и оно действовало, несмотря на отключение питания шифровалки. Стратмору, разумеется, это было хорошо известно, но даже когда Сьюзан порывалась уйти через главный выход, он не обмолвился об этом ни единым словом.

 Видишь? - спросил Бринкерхофф, наклоняясь над ней и показывая цифру.  - Это СЦР. Миллиард долларов.
