The CODATA recommended values of fundamental physical constants are published at the NIST Reference on Constants, Units, and Uncertainty.

Diffraction Limit The detail of a physical object that an optical instrument can reproduce in an image has limits that are mandated by inviolate laws of physics, whether formulated by the diffraction equations in the wave theory of light or the Uncertainty Principle for photons in quantum mechanics.

Complementarity and Uncertainty dictate that all properties and actions in the physical world are therefore non-deterministic to some degree.

He easily bests Spider-Man in a physical confrontation at their first meeting, in which he did display superhuman strength and reflexes, catching and crushing a pool ball with a single hand, seems unconcerned about being killed in a bomb blast — even helping Spidey look underneath tables for the Green Goblin's " special " explosive — and takes several of Green Goblin's razor-bats through his back seemingly without pain in " The Uncertainty Principle ".

Uncertainty and variable crop yields led to major settlement reorganizations.

He also uses brass knuckles as weapons, unlike other interpretations of the character, but retains his usual strength, as seen in " The Uncertainty Principle ".

Uncertainty overcoming itself is the precondition of the quest for new and more precise information about the world.

Ian Barbour in his book Issues in Science and Religion ( 1966 ), p. 133, cites Arthur Eddington's The Nature of the Physical World ( 1928 ) for a text that argues The Heisenberg Uncertainty Principles provides a scientific basis for " the defense of the idea of human freedom " and his Science and the Unseen World ( 1929 ) for support of philosophical idealism " the thesis that reality is basically mental ".

The World Wide Web Consortium ( W3C ) Incubator Group for Uncertainty Reasoning for the World Wide Web ( URW3-XG ) final report lumps these problems together under the single heading of " uncertainty ".

Uncertainty in the law is a serious problem, insofar as the published precedent of courts in a common law system is supposed to constitute " a clear guide for the conduct of individuals, to enable them to plan their affairs with assurance against untoward surprise.

Arrow analysed this issue for medical care ( a 1963 paper entitled " Uncertainty and the Welfare Economics of Medical Care ", in the American Economic Review ); later researchers investigated many other markets, particularly second-hand assets, online auctions and insurance.

The most commonly used procedure for calculating measurement uncertainty is described in the Guide to the Expression of Uncertainty in Measurement ( often referred to as " the GUM ") published by ISO.

A derived work is for example the National Institute for Standards and Technology ( NIST ) publication NIST Technical Note 1297 " Guidelines for Evaluating and Expressing the Uncertainty of NIST Measurement Results " and the Eurachem / Citac publication " Quantifying Uncertainty in Analytical Measurement " ( available at the Eurachem homepage ).

< li > Uncertainty has been a common theme in art, both as a thematic device ( see, for example, the indecision of Hamlet ), and as a quandary for the artist ( such as Martin Creed's difficulty with deciding what artworks to make ).</ li ></ ul >

The term Copenhagen interpretation of quantum mechanics was often used interchangeably with and as a synonym for Heisenberg's Uncertainty Principle by detractors ( such as Einstein and the physicist Alfred Landé ) who believed in determinism and saw the common features of the Bohr-Heisenberg theories as a threat.

The Uncertainty Principle states that for a pair of conjugate variables such as position / momentum and energy / time, it is impossible to have a precisely determined value of each member of the pair at the same time.

In it he integrates Gödel's Incompleteness Theorem, Heisenberg's Uncertainty principle, and the Second Law of Thermodynamics to provide a context and rationale for the development of the OODA Loop.

Akerlof is perhaps best known for his article, " The Market for Lemons: Quality Uncertainty and the Market Mechanism ", published in Quarterly Journal of Economics in 1970, in which he identified certain severe problems that afflict markets characterized by asymmetrical information, the paper for which he was awarded the Nobel Prize.

The Cone of Uncertainty explains some of this as the planning made on the initial phase of the project suffers from a high degree of uncertainty.

In his seminal work Risk, Uncertainty, and Profit University of Chicago economist Frank Knight ( 1921 ) established the important distinction between risk and uncertainty:

* Uncertainty avoidance is the coping with uncertainty about the future.

* Uncertainty models, uncertainty quantification, and uncertainty processing in engineering

* Guide to the Expression of Uncertainty in Measurement ( ISO ), see Measurement uncertainty

His most influential work was Risk, Uncertainty and Profit ( 1921 ) from which was coined the term Knightian uncertainty.

Uncertainty and Sensitivity Analysis offer valid tools for characterizing the uncertainty associated with a model.

Uncertainty analysis ( UA ) quantifies the uncertainty in the outcome of a model.

Uncertainty arising from different sources — errors in the data, parameter estimation procedure, alternative model structures — are propagated through the model for uncertainty analysis and their relative importance is quantified via sensitivity analysis.

:* Uncertainty node ( corresponding to each uncertainty to be modeled ) is drawn as an oval.

Knightian uncertainty is named after University of Chicago economist Frank Knight ( 1885 – 1972 ), who distinguished risk and uncertainty in his work Risk, Uncertainty, and Profit:

Uncertainty Reduction Theory discusses the processes through which individuals go to reduce uncertainty about one another when placed in an unknown or unfamiliar environment ( Berger & Calabrese, 100 ).

Expectation Violations Theory has its roots in Uncertainty Reduction research, which attempts to predict and explain how communication is used to reduce the uncertainty among people involved in conversations with one another the first time they meet.

Uncertainty reduction theory focuses on when and why individuals use communication to reduce the uncertainty they have about others.

Kellerman and Reynolds ( 1990 ) pointed out that sometimes there are high level of uncertainty in interaction that no one wants to reduce ( Miller, 180 – 183 ). As a result of the critique, researchers formed the Uncertainty Management theory.

While temporarily at the University of Copenhagen, German physicist Werner Heisenberg formulated his famous Uncertainty principle, and, with Max Born and Pascual Jordan, accomplished the first complete and correct definition of quantum mechanics, through the invention of Matrix mechanics.

In that sense the behavior of light in this apparatus is deterministic, but there is no way to predict where in the resulting interference pattern any individual photon will make its contribution ( although, there may be ways to use weak measurement to acquire more information without violating the Uncertainty principle ).

* Uncertainty principle

The Uncertainty Principle is a mathematical principle that follows from the quantum mechanical definition of the operators of momentum and position ( namely, the lack of commutativity between them ) and that explains the behavior of the universe at atomic and subatomic scales.
