Cybernetics
Cybernetics is a field of systems theory that studies circular causal systems whose outputs are also inputs, such as feedback systems. It is concerned with the general principles of circular causal processes, including in ecological, technological, biological, cognitive and social systems and also in the context of practical activities such as designing, learning, and managing. The field is named after an example of circular causal feedback—that of steering a ship (the ancient Greek κυβερνήτης (''kybernḗtēs'') means "helmsperson"). In steering a ship, the helmsperson adjusts their steering in continual response to the effect it is observed as having, forming a feedback loop through which a steady course can be maintained in a changing environment, responding to disturbances from cross winds and tide. Cybernetics' transdisciplinary character has meant that it intersects with a number of other fields, leading to it having both wide influence and diverse interp ...

Cybernetics
Cybernetics is a wide-ranging field concerned with circular causality, such as feedback, in regulatory and purposive systems. Cybernetics is named after an example of circular causal feedback, that of steering a ship, where the helmsperson maintains a steady course in a changing environment by adjusting their steering in continual response to the effect it is observed as having. Cybernetics is concerned with circular causal processes such as steering however they are embodied,Ashby, W. R. (1956). An introduction to cybernetics.

Gregory Bateson
Gregory Bateson (9 May 1904 – 4 July 1980) was an English anthropologist, social scientist, linguist, visual anthropologist, semiotician, and cyberneticist whose work intersected that of many other fields. His writings include '' Steps to an Ecology of Mind'' (1972) and ''Mind and Nature'' (1979). In Palo Alto, California, Bateson and colleagues developed the double-bind theory of schizophrenia. Bateson's interest in systems theory forms a thread running through his work. He was one of the original members of the core group of the Macy conferences in Cybernetics (1941–1960), and the later set on Group Processes (1954–1960), where he represented the social and behavioral sciences. He was interested in the relationship of these fields to epistemology. His association with the editor and author Stewart Brand helped widen his influence. Early life and education Bateson was born in Grantchester in Cambridgeshire, England, on 9 May 1904. He was the third and youngest son ...

Governor (device)
A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow of steam. History Centrifugal governors were used to regulate the distance and pressure between millstones in windmills since the 17th century. Early steam engines employed a purely reciprocating motion, and were used for pumping water – an application that could tolerate variations in the working speed. It was not until the Scottish engineer James Watt introduced the ''rotative'' steam engine, for driving factory machinery, that a constant operating speed became necessary. Between the years 1775 and 1800, Watt, in partnership with industrialist Matthew Boulton, produced some 500 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Clerk Maxwell
James Clerk Maxwell (13 June 1831 – 5 November 1879) was a Scottish mathematician and scientist responsible for the classical theory of electromagnetic radiation, which was the first theory to describe electricity, magnetism and light as different manifestations of the same phenomenon. Maxwell's equations for electromagnetism have been called the " second great unification in physics" where the first one had been realised by Isaac Newton. With the publication of "A Dynamical Theory of the Electromagnetic Field" in 1865, Maxwell demonstrated that electric and magnetic fields travel through space as waves moving at the speed of light. He proposed that light is an undulation in the same medium that is the cause of electric and magnetic phenomena. (This article accompanied an 8 December 1864 presentation by Maxwell to the Royal Society. His statement that "light and magnetism are affections of the same substance" is at page 499.) The unification of light and electrical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arturo Rosenblueth
Arturo Rosenblueth Stearns (October 2, 1900 – September 20, 1970) was a Mexican researcher, physician and physiologist, who is known as one of the pioneers of cybernetics. Biography Rosenblueth was born in 1900 in Ciudad Guerrero, Chihuahua. He began his studies in Mexico City, then traveled to Berlin and Paris where he obtained his medical degree. Returning to Mexico City in 1927, he engaged in teaching and research in physiology. In 1930 he obtained a Guggenheim Scholarship and moved to Harvard University, to the department of Physiology, then directed by Walter Cannon. With Cannon he explored the chemical mediation of homeostasis. Rosenblueth cowrote research papers with both Cannon and Norbert Wiener, pioneer of cybernetics. Notably he was the lead author for the 1943 article 'Behavior, Purpose and Teleology' that was co-written by Wiener and Julian Bigelow and which was published in Philosophy of Science. Rosenblueth was an influential member of the core group at the Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Governance
Governance is the process of interactions through the laws, social norm, norms, power (social and political), power or language of an organized society over a social system (family, tribe, formal organization, formal or informal organization, a territory or across territories). It is done by the government of a state (polity), state, by a market (economics), market, or by a social network, network. It is the decision-making among the actors involved in a collective problem that leads to the creation, reinforcement, or reproduction of social norms and institutions". In lay terms, it could be described as the political processes that exist in and between formal institutions. A variety of entities (known generically as governing bodies) can govern. The most formal is a government, a body whose sole responsibility and authority is to make binding decisions in a given geopolitical system (such as a sovereign state, state) by establishing laws. Other types of governing include an o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helmsman
A helmsman or helm (sometimes driver) is a person who steering, steers a ship, sailboat, submarine, other type of maritime vessel, or spacecraft. The rank and seniority of the helmsman may vary: on small vessels such as fishing vessels and yachts, the functions of the helmsman are combined with that of the skipper (boating), skipper; on larger vessels, there is a separate officer of the watch who is responsible for the safe navigation of the ship and gives orders to the helmsman, who physically steers the ship in accordance with those orders. In the merchant navy, the person at the Ship's wheel, helm is usually an able seaman, particularly during ship arrivals, departures, and while maneuvering in restricted waters or other conditions requiring precise steering. An ordinary seaman is commonly restricted to steering in open waters. Moreover, military ships may have a Seaman (rank), seaman or quartermaster at the helm. A professional helmsman maintains a steady course, properly ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Alcibiades
The ''First Alcibiades'', also referred to as ''Alcibiades Major'' and abbreviated as ''Alcibiades I'' ( el, Ἀλκιβιάδης αʹ), is a dialogue depicting Socrates in conversation with Alcibiades. It is ascribed to Plato, although scholars are divided on the question of its authenticity. Content In the preface Alcibiades is described as an ambitious young man who is eager to enter public life. He is extremely proud of his good looks, noble birth, many friends, possessions and his connection to Pericles, the leader of the Athenian state. Alcibiades has many admirers and had many lovers but they have all run away, afraid of his coldness. Socrates was the first of his lovers but he has not spoken to him for many years. Now the older man tries to help the youth with his questions before Alcibiades presents himself in front of the Athenian assembly. For the rest of the dialogue Socrates explains the many reasons why Alcibiades needs him. By the end of ''Alcibiades I'', the yo ...

Republic (Plato)
The ''Republic'' ( grc-gre, Πολῑτείᾱ, Politeia; ) is a Socratic dialogue, authored by Plato around 375 BCE, concerning justice (), the order and character of the just city-state, and the just man. It is Plato's best-known work, and one of the world's most influential works of philosophy and political theory, both intellectually and historically. In the dialogue, Socrates discusses the meaning of justice and whether the just man is happier than the unjust man with various Athenians and foreigners.In ancient times, the book was alternately titled ''On Justice'' (not to be confused with the spurious dialogue of the same name). They consider the natures of existing regimes and then propose a series of different, hypothetical cities in comparison, culminating in Kallipolis (Καλλίπολις), a utopian city-state ruled by a philosopher-king. They also discuss ageing, love, theory of forms, the immortality of the soul, and the role of the philosopher and of poe ...
