Norbert Wiener, a child prodigy and a great mathematician, coined the term ' cybernetics' to characterize a very general science of 'control and communication in. Cybernetics or Communication and Control in the Animal and the Machine - Norbert Wiener. Cybernetics is the study of human/machine interaction guided by the Norbert Wiener founded the field with his in his book Cybernetics: or Control and.

In other words, this concept concern the control of process between human and machine could be able to influence the entropy of the natural world by the humans, especially in the the quality of man's life, and cybernetics ameid at this result.

For this reason the fundamental concept that Weiner scientists but also by the 'average man'. In this except Weiner identify in Cybernetics is the mechanism of feedback. Permission to make digital or hard copies of all or part of this work for 4.

He started from the analysis of copies bear this notice and the full citation on the first page. Although these organs communicate our reaction to the muscles.

Weiner points that these informations, received through 6. Is that we communication technology from mechanical to digital, in this text call memory.

Wiener says that we call information the content of Norbert Weiner define that the most strinking topic is the analysis the what we exchange with the external world and what we adjust and definition of the concept of feedback. Today, of course, this that to it.

The interesting thing is 4. Our derived his ideas. Weiner comes to concept of cybernetics after a society, said Weiner, is characterized by a greater amount of profound and detailed analysis of the processes of process of information never seen before.

The fact that we are communication between human beings and between them and increasingly surrounded by machines -that allow us to both send their environment.

With this Weiner define not only the basics for and receive information- not only mean that the quality of that a useful discipline for the design of machines that are more informations affect the quality of our life.

Weiner noted that if similar and related to the mechanisms of human beings. He entropy is a measure of disorganization, the information can be comes to a better understanding of these mechanisms through a carried by a set of messages, that became a measure of comparison between two things that permeate the current society. If the messages are the modalities by which men But we must't overlook the fact that Weiner has developed impart order to the envrionment, we can use messages can also for cybernetics within a context dominated by the production and communicate with the machines.

Weiner noted that modern control of man over machine and then the man on his machines like electronic calculators have some receptors for environment. This perspective I think today has been largely understand the messages coming from the outside, like a human overcome, as evidenced by contemporary physics and ecology.

This chapter lays down the foundations for the mathematical treatment of negative feedback in automated control systems. The opening passage illustrates the effect of faulty feedback mechanisms by the example of patients suffering from various forms of ataxia. He then discusses railway signalling, the operation of a thermostat , and a steam engine centrifugal governor. The rest of the chapter is mostly taken up with the development of a mathematical formulation of the operation of the principles underlying all of these processes.

More complex systems are then discussed such as automated navigation, and the control of non-linear situations such as steering on an icy road. He concludes with a reference to the homeostatic processes in living organisms.

This chapter opens with a discussion of the relative merits of analog computers and digital computers which Wiener referred to as analogy machines and numerical machines , and maintains that digital machines will be more accurate, electronic implementations will be superior to mechanical or electro-mechanical ones, and that the binary system is preferable to other numerical scales.

After discussing the need to store both the data to be processed and the algorithms which are employed for processing that data, and the challenges involved in implementing a suitable memory system, he goes on to draw the parallels between binary digital computers and the nerve structures in organisms. Among the mechanisms that he speculated for implementing a computer memory system was "a large array of small condensers [ie capacitors in today's terminology] which could be rapidly charged or discharged", thus prefiguring the essential technology of modern dynamic random-access memory chips.

Virtually all of the principles which Wiener enumerated as being desirable characteristics of calculating and data processing machines have been adopted in the design of digital computers, from the early mainframes of the s to the latest microchips.

This brief chapter is a philosophical enquiry into the relationship between the physical events in the central nervous system and the subjective experiences of the individual.

It concentrates principally on the processes whereby nervous signals from the retina are transformed into a representation of the visual field. It also explores the various feedback loops involved in the operation of the eyes: The chapter concludes with an outline of the challenges presented by attempts to implement a reading machine for the blind.

Wiener opens this chapter with the disclaimers that he is neither a psychopathologist nor a psychiatrist, and that he is not asserting that mental problems are failings of the brain to operate as a computing machine. However, he suggests that there might be fruitful lines of enquiry opened by considering the parallels between the brain and a computer.

He employed the archaic-sounding phrase "computing machine", because at the time of writing the word "computer" referred to a person who is employed to perform routine calculations. He then discussed the concept of 'redundancy' in the sense of having two or three computing mechanisms operating simultaneously on the same problem, so that errors may be recognised and corrected.

Starting with an outline of the hierarchical nature of living organisms, and a discussion of the structure and organisation of colonies of symbiotic organisms, such as the Portuguese Man o' War , this chapter explores the parallels with the structure of human societies, and the challenges faced as the scale and complexity of society increases.

The Chapter closes with speculation about the possibility of constructing a chess-playing machine , and concludes that it would be conceivable to build a machine capable of a standard of play better than most human players but not at expert level. Such a possibility seemed entirely fanciful to most commentators in the s, bearing in mind the state of computing technology at the time, although events have turned out to vindicate the prediction — and even to exceed it. Starting with an examination of the learning process in organisms, Wiener expands the discussion to John von Neumann 's theory of games , and the application to military situations.

He then speculates about the manner in which a chess-playing computer could be programmed to analyse its past performances and improve its performance. This proceeds to a discussion of the evolution of conflict, as in the examples of matador and bull, or mongoose and cobra, or between opponents in a tennis game. He discusses various stories such as The Sorcerer's Apprentice , which illustrate the literal-minded nature of "magical" processes, the context being the drawing of attention to the need for caution in delegating to machines the responsibility for warfare strategy in an age of Nuclear weapons.

The chapter concludes with a discussion of the possibility of self-replicating machines and the work of Professor Dennis Gabor in this area. This chapter opens with a discussion of the mechanism of evolution by Natural Selection , which he refers to as " phylogenetic learning ", since it is driven by a feedback mechanism caused by the success or otherwise in surviving and reproducing; and modifications of behaviour over a lifetime in response to experience, which he calls " ontogenetic learning ".

He suggests that both processes involve non-linear feedback, and speculates that the learning process is correlated with changes in patterns of the rhythms of the waves of electrical activity that can be observed on an electroencephalograph. After a discussion of the technical limitations of earlier designs of such equipment, he suggests that the field will become more fruitful as more sensitive interfaces and higher performance amplifiers are developed and the readings are stored in digital form for numerical analysis, rather than recorded by pen galvanometers in real time - which was the only available technique at the time of writing.

He then develops suggestions for a mathematical treatment of the waveforms by Fourier analysis , and draws a parallel with the processing of the results of the Michelson-Morley experiment which confirmed the constancy of the velocity of light , which in turn led Einstein to develop the Theory of Special Relativity.

As with much of the other material in this book, these pointers have been both prophetic of future developments and suggestive of fruitful lines of research and enquiry. The book provided a foundation for research into electronic engineering , computing both analog and digital , servomechanisms , automation , telecommunications and neuroscience.

It also created widespread public debates on the technical, philosophical and sociological issues it discussed. And it inspired a wide range of books on various subjects peripherally related to its content. Maxwell Maltz titled his pioneering self-development work " Psycho-Cybernetics " in reference to the process of steering oneself towards a pre-defined goal by making corrections to behaviour. Much of the personal development industry and the Human potential movement is said to be derived from Maltz's work.

Cybernetics became a surprise bestseller and was widely read beyond the technical audience that Wiener had expected. In response he wrote The Human Use of Human Beings in which he further explored the social and psychological implications in a format more suited to the non-technical reader. In , Marie Neurath produced a children's book Machines which seem to Think [1] , which introduced the concepts of Cybernetics , control systems and negative feedback in an accessible format.

Weiner claims that the Lebesgue integral had unexpected but important implications in establishing the validity of Gibbs' work on the foundations of statistical mechanics. Weiner noted that if similar and related to the mechanisms of human beings.

It also recognises substantial work of a cybernetic nature applied outside the field itself.
