Usage examples of feedback.

I should have done was to attack the problem from the beginning and develop on my own initiative a fairly comprehensive theory of feedback mechanisms.

Those tangible engineering practicalities forced Wiener and Bigelow to confront the enigmatic feedback process and the thorny problems Wiener did not tend to in his project with Lee in China.

Now, once again, in the push to translate his prediction theory into a viable production prototype, feedback emerged as the focal point and final obstacle in his war work with Bigelow.

The Greeks invented automatic wine dispensers and water clocks controlled, like modern plumbing, by the feedback action of a float.

But, as it had been with electronic circuits for decades after their first practical applications, there was scant theory beneath those diverse feedback inventions, and scarcely an inkling among engineers that one form of feedback had anything to do with another.

Wiener, the discovery of feedback was tantamount to the discovery of fire.

Wiener drew the connections between feedback in the technical sense, in the physiological sense, and the innumerable feedback loops wired into the living electrical networks of the brain and nervous system.

And he made one more link that brought the feedback process fully into focus.

Bigelow built into their prototype predictor the feedback circuits needed to incorporate the tracking data derived from radar signals reflecting off enemy warplanes, and to feed that stream of new inputs to the computers targeting apparatus.

Yet, once again, he found that the complexities of feedback would not be so easily resolved in practice.

Rosenblueth told his audience about messages, feedback, and the surprising similarities he and Wiener and the engineer Julian Bigelow were finding in the actions of electronic devices, automatic machines, and human nervous systems.

Among the brain scientists, his notions of feedback and circularity struck a resonant chord.

Its results were checked by the fastidious error-correction circuitry von Neumann had prescribed in his design, and Bigelow was the perfect person to implement those archetypal feedback mechanisms.

Iatmul tribe of New Guinea, which, as Bateson noted, played a stabilizing feedback role when aggressive urges among male tribesmen threatened to break out in internal warfare.

In 1789, Watt first used that term in a technical context to describe the flyball feedback apparatus that controlled the speed of his steam engine.
