The word cybernetics refers to the theory of message transmission among people and machines. The thesis of the book is that: society can only be understood through a study of the messages and the communication facilities which belong to it; and that in the future development of these messages and communication facilities, messages between man and machines, between machines and man, and between ...
In An Introduction to Cybernetics, Ashby used set cardinality, or variety, as a measure of information. With this he formulated his Law of Requisite Variety. Mathematically, the law is a statement about how "in a two-person game the variety possible is determined by the number of possible choices open to the two players". [14]
Cybernetics is the transdisciplinary study of circular causal [1] processes such as feedback and recursion, where the effects of a system's actions (its outputs) return as inputs to that system, influencing subsequent action. [2]
Reviews of An Introduction to Cybernetics were mostly positive, [2] [4] [6] alongside some mixed opinions. [7] [8] Positive reviews highlighted Ashby's clear explanations of complex concepts, as well as his inclusion of examples and exercises. Detractors were critical of Ashby's marked new vocabulary, replacing the usual terminology even when ...
The opening passage illustrates the effect of faulty feedback mechanisms by the example of patients with 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 ...
Pickering considers Cybernetics as a type of nomad science that, instead of seeking to dominate reality as its modern counterpart (thus leading to processes of enframing, following Heidegger) rather develops an ontological theatre between humans and non-humans. In this book, Pickering explores projects that intertwine, for instance, technology ...
Cybernetical physics is a scientific area on the border of cybernetics and physics which studies physical systems with cybernetical methods. Cybernetical methods are understood as methods developed within control theory, information theory, systems theory and related areas: control design, estimation, identification, optimization, pattern recognition, signal processing, image processing, etc ...
Another example is Stir Fry Texts, by Jim Andrews, which is a cybertext where there are many layers of text, and as you move your mouse over the words, the layers beneath them are 'dug' through. [15] The House is another example of a cybertext where one might assume a description of the piece as follows: It is an unruly text, the words don't ...
