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]
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 ...
Having decided it should be a number, he tried to think what an "ordinary number" should be. He ruled out non-integers, then he remembered having worked as a "prop-borrower" for John Cleese on his Video Arts training videos. Cleese needed a funny number for the punchline to a sketch involving a bank teller (himself) and a customer (Tim Brooke ...
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 ...

The video Alvarez captured that day shows the alligator from the view of the tower. The alligator slithers through the water holding a bloated snake with the ends missing in its mouth. "That's so ...
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]
The hourlong program provides a mix of heartfelt reflection and levity or, as Foxx himself put it, "If I can stay funny, I can stay alive." What Had Happened Was. Jamie Foxx at the Alliance ...
