Principle
A principle is a proposition or value that is a guide for behavior or evaluation. In law, it is a Legal rule, rule that has to be or usually is to be followed. It can be desirably followed, or it can be an inevitable consequence of something, such as the laws observed in nature or the way that a system is constructed. The principles of such a system are understood by its users as the essential characteristics of the system, or reflecting system's designed purpose, and the effective operation or use of which would be impossible if any one of the principles was to be ignored. A system may be explicitly based on and implemented from a document of principles as was done in IBM's IBM System/360 architecture, 360/370 ''Principles of Operation''. Examples of principles are, entropy (other), entropy in a number of fields, least action in physics, those in descriptive comprehensive and fundamental law: doctrines or assumptions forming normative rules of conduct, separation of chur ...

Precautionary Principle
The precautionary principle (or precautionary approach) is a broad epistemological, philosophical and legal approach to innovations with potential for causing harm when extensive scientific knowledge on the matter is lacking. It emphasizes caution, pausing and review before leaping into new innovations that may prove disastrous. Critics argue that it is vague, self-cancelling, unscientific and an obstacle to progress. In an engineering context, the precautionary principle manifests itself as the factor of safety, discussed in detail in the monograph of Elishakoff. It was apparently suggested, in civil engineering, by Belindorde Bélidor, Bernard Forest, La science des ingénieurs, dans la conduite des travaux de fortification et d'architecture civile, Paris: Chez Claude Jombert 1729 in 1729. Interrelation between safety factor and reliability is extensively studied by engineers and philosophers. The principle is often used by policy makers in situations where there is the poss ...

Anthropic Principle
The anthropic principle, also known as the "observation selection effect", is the hypothesis, first proposed in 1957 by Robert Dicke, that there is a restrictive lower bound on how statistically probable our observations of the universe are, because observations could only happen in a universe capable of developing intelligent life. Proponents of the anthropic principle argue that it explains why this universe has the age and the fundamental physical constants necessary to accommodate conscious life, since if either had been different, we would not have been around to make observations. Anthropic reasoning is often used to deal with the notion that the universe seems to be finely tuned for the existence of life. There are many different formulations of the anthropic principle. Philosopher Nick Bostrom counts them at thirty, but the underlying principles can be divided into "weak" and "strong" forms, depending on the types of cosmological claims they entail. The weak anthropic p ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Reality Principle
In Freudian psychology and psychoanalysis, the reality principle (german: Realitätsprinzip) is the ability of the mind to assess the reality of the external world, and to act upon it accordingly, as opposed to acting on the pleasure principle. Allowing the individual to defer (put off) instant gratification, the reality principle is the governing principle of the actions taken by the ego, after its slow development from a "pleasure-ego" into a "reality-ego": it may be compared to the triumph of reason over passion, head over heart, rational over emotional mind, human values over animal instinct. History Freud argued that “an ego thus educated has become ‘reasonable’; it no longer lets itself be governed by the pleasure principle, but obeys the reality principle, which also, at bottom, seeks to obtain pleasure, but pleasure which is assured through taking account of reality, even though it is pleasure postponed and diminished”. In his introductory lectures of 1915, at t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Least Action
The stationary-action principle – also known as the principle of least action – is a variational principle that, when applied to the '' action'' of a mechanical system, yields the equations of motion for that system. The principle states that the trajectories (i.e. the solutions of the equations of motion) are ''stationary points'' of the system's ''action functional''. The term "least action" is a historical misnomer since the principle has no minimality requirement: the value of the action functional need not be minimal (even locally) on the trajectories. The principle can be used to derive Newtonian, Lagrangian and Hamiltonian equations of motion, and even general relativity (see Einstein–Hilbert action). In relativity, a different action must be minimized or maximized. The classical mechanics and electromagnetic expressions are a consequence of quantum mechanics. The stationary action method helped in the development of quantum mechanics. In 1933, the physicist ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Principle Of Relativity
In physics, the principle of relativity is the requirement that the equations describing the laws of physics have the same form in all admissible frames of reference. For example, in the framework of special relativity the Maxwell equations have the same form in all inertial frames of reference. In the framework of general relativity the Maxwell equations or the Einstein field equations have the same form in arbitrary frames of reference. Several principles of relativity have been successfully applied throughout science, whether implicitly (as in Newtonian mechanics) or explicitly (as in Albert Einstein's special relativity and general relativity). Basic concepts Certain principles of relativity have been widely assumed in most scientific disciplines. One of the most widespread is the belief that any law of nature should be the same at all times; and scientific investigations generally assume that laws of nature are the same regardless of the person measuring them. These ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Archimedes Principle
Archimedes' principle (also spelled Archimedes's principle) states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces. Archimedes' principle is a law of physics fundamental to fluid mechanics. It was formulated by Archimedes of Syracuse. Explanation In ''On Floating Bodies'', Archimedes suggested that (c. 246 BC): Archimedes' principle allows the buoyancy of any floating object partially or fully immersed in a fluid to be calculated. The downward force on the object is simply its weight. The upward, or buoyant, force on the object is that stated by Archimedes' principle above. Thus, the net force on the object is the difference between the magnitudes of the buoyant force and its weight. If this net force is positive, the object rises; if negative, the object sinks; and if zero, the object is neutrally buoyant—that is, it remains in place without either rising o ...

Pleasure Principle (psychology)
In Freudian psychoanalysis, the pleasure principle (german: Lustprinzip) is the instinctive seeking of pleasure and avoiding of pain to satisfy biological and psychological needs. Specifically, the pleasure principle is the driving force guiding the id. Precursors Epicurus in the ancient world, and Jeremy Bentham in the modern, laid stress upon the role of pleasure in directing human life, the latter stating: "Nature has placed mankind under the governance of two sovereign masters, ''pain'' and ''pleasure''". Freud's most immediate predecessor and guide however was Gustav Theodor Fechner and his psychophysics. Freudian developments Freud used the idea that the mind seeks pleasure and avoids pain in his ''Project for a Scientific Psychology'' of 1895, as well as in the theoretical portion of ''The Interpretation of Dreams'' of 1900, where he termed it the 'unpleasure principle'. In the ''Two Principles of Mental Functioning'' of 1911, contrasting it with the reality principle, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Mediocrity Principle
The mediocrity principle is the philosophical notion that "if an item is drawn at random from one of several sets or categories, it's more likely to come from the most numerous category than from any one of the less numerous categories". The principle has been taken to suggest that there is nothing very unusual about the evolution of the Solar System, Earth's history, the evolution of biological complexity, human evolution, or any one nation. It is a heuristic in the vein of the Copernican principle, and is sometimes used as a philosophical statement about the place of humanity. The idea is to assume mediocrity, rather than starting with the assumption that a phenomenon is special, privileged, exceptional, or even superior. Extraterrestrial life The mediocrity principle suggests, given the existence of life on Earth, that should life exist elsewhere in the universe, it will typically exist on Earth-like planets. Measurement of distance to stars The mediocrity principle was ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Legal Rule
Law is a set of rules that are created and are law enforcement, enforceable by social or governmental institutions to regulate behavior,Robertson, ''Crimes against humanity'', 90. with its precise definition a matter of longstanding debate. It has been variously described as a Social science#Law, science and as the art of justice. State-enforced laws can be made by a group legislature or by a single legislator, resulting in statutes; by the executive through decrees and regulations; or established by judges through precedent, usually in common law jurisdictions. Private individuals may create legally binding contracts, including arbitration agreements that adopt Alternative dispute resolution, alternative ways of resolving disputes to standard court litigation. The creation of laws themselves may be influenced by a constitution, written or tacit, and the rights encoded therein. The law shapes politics, economics, history and society in various ways and serves as a mediator of ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Homestead Principle
The homestead principle is the principle by which one gains ownership of an unowned natural resource by performing an act of original appropriation. Appropriation could be enacted by putting an unowned resource to active use (as with using it for produce some product), joining it with previously acquired property or by marking it as owned (as with livestock branding). Proponents of intellectual property hold that ideas can also be homesteaded by originally creating a virtual or tangible representation of them. Others argue that since tangible manifestations of a single idea will be present in many places, including within the minds of people, this precludes their being owned in most or all cases. Homesteading is one of the foundations of Rothbardian anarcho-capitalism and right-libertarianism. In political philosophy John Locke In his 1690 work '' Second Treatise of Government'', Enlightenment philosopher John Locke advocated the Lockean proviso which allows fo ...

Territorial Principle
The territorial principle (also territoriality principle) is a principle of public international law which enables a sovereign state to exercise exclusive jurisdiction over individuals and other legal persons within its territory. It includes both the right to prosecute individuals for criminal offences committed within its borders, as well as the right to arrest and apprehend individuals within its territory. Its corollary bars states from exercising jurisdiction within the territory of other states without their express consent, unless such an exercise can be based on other principles of jurisdiction, such as the principle of nationality, the passive personality principle, the protective principle, and possibly, the principle of universal jurisdiction. The ''Lotus'' case was a key court ruling on the territoriality principle. In 1926, a French vessel collided with a Turkish vessel, causing the death of several Turkish nationals.
