Psionic Cybernetics

Cybernetics is a term coined in the 1940s. It is a system of understanding, prediction, and controlling space-time events. The scope of cybernetics extends into many different fields and its dynamics works exceptionally well in each field. Last Updated: November 2, 2021 Introduction Cybernetics is a transdisciplinary and "antidisciplinary" approach concerned with regulatory and purposive systems—their structures, constraints, and possibilities. The core concept of the discipline is circular causality or feedback—that is, where the outcomes of actions are taken as inputs for further action. The word “Cybernetics” was first defined by Norbert Wiener who wrote a book with the same title in 1948. It stemmed from the conditions of World War I and his involvement as a scientist and weapons engineer using the concepts of Brownian motion and the Wiener Filter. Brownian motion is the random motion of particles suspended in a medium that can be a liquid or a gas. It suggest that the pattern of motion is random fluctuations, followed by relocation to another location, based upon the previous movements. The pattern continues as the substance and particles seek thermal equilibrium, which is defined by the temperature as the independent variable. The Wiener Filter is a filter that produces an estimate of either a desired process or a random process. They are linear time-invariant filtering systems which mean that the event is independent of the time of occurrence or when the input was applied. This is applied to observed noise processes which include: known stationary signal and noise spectra, and additive noise, where interference is added to the signal during the communication. The Wiener filter minimizes the mean square error between the estimated random process (random variable) and the desired process (range or parameter of sample) as either the predictor or the estimator. Wiener's Cybernetics thus he termed as the study of control and communication in the animal and the machine. He used the Greek κυβερνήτης (kybernētēs, steersman, governor, pilot, or rudder). This understanding of control and communication is one of his greater contributions to humanity, blending abstract science with the sociological science and engineering and apply them…
