Endogeneity can be the result of simultaneity, where causality flows back and forth between both the dependent and independent variable.

* Physics ( The idea of simultaneity has many difficulties, both in practice and theory.

In Western jurisprudence, concurrence ( also contemporaneity or simultaneity ) is the apparent need to prove the simultaneous occurrence of both actus reus (" guilty action ") and mens rea (" guilty mind "), to constitute a crime ; except in crimes of strict liability.

At a 1997 conference on " Globalization and Indigenous Culture ," Robertson said that glocalization " means the simultaneity --- the co-presence --- of both universalizing and particularizing tendencies.

In relativity, simultaneity is relative to each observer and thus the ladder can fit into the garage in both instances.

The principle it works on, the constant of simultaneity, is analogous in some ways to gravity ... One point has to be fixed, on a planet of certain mass, but the other end is portable.

This is true not only with syntagmatic succession in relation with paradigmatic simultaneity, but also, in a broader sense, between diachronic succession in History related with synchronic simultaneity inside a " system of distinct signs ".

This theory has a wide range of consequences which have been experimentally verified, including counter-intuitive ones such as length contraction, time dilation and relativity of simultaneity, contradicting the classical notion that the duration of the time interval between two events is equal for all observers.

* In marketing, simultaneity is one of the characteristics of a service which differentiates it from a product.

The problem can be understood in terms of the relativity of simultaneity in special relativity, which says that different inertial reference frames will disagree on whether two events at different locations happened " at the same time " or not, and they can also disagree on the order of the two events ( technically, these disagreements occur when spacetime interval between the events is ' space-like ', meaning that neither event lies in the future light cone of the other ).

If one of the two events represents the sending of a signal from one location and the second event represents the reception of the same signal at another location, then as long as the signal is moving at the speed of light or slower, the mathematics of simultaneity ensures that all reference frames agree that the transmission-event happened before the reception-event.

This technique of representing simultaneity, multiple viewpoints ( or relative motion ) is pushed to a high degree of complexity in Gleizes ' monumental Le Dépiquage des Moissons ( Harvest Threshing ), exhibited at the 1912 Salon de la Section d ' Or, Le Fauconnier ’ s Abundance shown at the Indépendants of 1911, and Delaunay's City of Paris, shown at the Indépendants in 1912.

Pitch simultaneity in particular is rarely a major consideration.

* 1898 – Henri Poincaré states that simultaneity is relative

The special theory of relativity can be viewed as the introduction of operational definitions for simultaneity of events and of distance, that is, as providing the operations needed to define these terms.

Special relativity suggests that the concept of simultaneity is not universal: according to the relativity of simultaneity, observers in different frames of reference can have different perceptions of whether a given pair of events happened at the same time or at different times, with there being no physical basis for preferring one frame's judgments over another's ( though in a case where one event A happens in the past light cone of another event B, all frames will agree that A happened in the past of B ).

However, there are some, such as Dean Zimmerman, who have argued that it is possible to accept the physical predictions of relativity while adopting an alternative interpretation of the theory ( For instance, see Lorentz ether theory ) in which there is a single privileged frame whose judgments about length, time and simultaneity are the " true " ones, even though there would be absolutely no empirical way to distinguish this frame from other frames, and no real experience could identify it.

Eternalism takes its inspiration from physics, especially the Rietdijk-Putnam argument, in which the relativity of simultaneity is used to show that each point in the universe can have a different set of events that are in its present moment.

In music the linear aspect is succession, either intervals or melody, as opposed to simultaneity or the vertical aspect.

To speak of " the shape of the universe ( at a point in time )" is ontologically naive from the point of view of special relativity alone: due to the relativity of simultaneity we cannot speak of different points in space as being " at the same point in time " nor, therefore, of " the shape of the universe at a point in time ".

Marie-Louise von Franz, a colleague of the eminent psychiatrist Carl Jung, noted that in these unconscious scientific discoveries the " always recurring and important factor ... is the simultaneity with which the complete solution is intuitively perceived and which can be checked later by discursive reasoning.

The idea of the need for simultaneity of sovereign state action is not itself a new idea-it is the basis of treaty and United Nations initiatives that nothing can be done on certain problems, such as disarmament, until all major players agree to a common timetable of implementing solutions.

If this sounds indulgent, it allows simultaneity, absolute space and time and a deterministic universe ( along with decoherence theory ) whilst the status-quo permits time travel / causality paradoxes, subjectivity in the measurement process and multiple universes.

Because spacetime diagrams incorporate Einstein's clock synchronization, there will be a requisite " jump in time " in the calculation made by a " suddenly returning astronaut " who inherits a " new meaning of simultaneity " in keeping with that clock synchronization ( with its lattice of clocks methodology ) as explained in Spacetime Physics by John A. Wheeler.

Léger ’ s The Wedding, also shown at the Salon des Indépendants in 1912, gave form to the notion of simultaneity by presenting different motifs as occurring within a single temporal frame, where responses to the past and present interpenetrate with collective force.

The conjunction of such subject-matter with simultaneity aligns Salon Cubism with early Futurist paintings by Umberto Boccioni, Gino Severini and Carlo Carrà ; themselves made in response to early Cubism.

The episode depicts Xander single-handedly saving the school, and potentially the world ( given the Hellmouth beneath it ) from an explosion in simultaneity against glimpses of the other Scoobies ' struggles with the hydra demon.

Within the framework of the theory and its terminology there is a relativity of simultaneity that affects how the specified events are aligned with respect to each other by observers in relative motion.

But there has not always been agreement as to how the writings of Metzinger and Gleizes should be interpreted, with respect to ' simultaneity ' of multiple view-points.

The common denominator between the special relativistic notions — the lack an absolute reference frame, metric transformations of the Lorenzian type, the relativity of simultaneity, the incorporation of the time dimension with three spatial dimensions — and the Cubist idea of mobile perspective ( observing the subject from several view-points simultaneously ) published by Jean Metzinger and Albert Gleizes was, in effect, a descendant from the work of Poincaré and others, at least from the theoretical standpoint.

Yet in relativity theory the constancy of light velocity in all inertial frames in connection with the relativity of simultaneity destroys this equality.

This is true not only with syntagmatic succession in relation with paradigmatic simultaneity, but also, in a broader sense, between diachronic succession in History related with synchronic simultaneity inside a " system of distinct signs ".

In Beethoven, the notes ' simultaneity may be considered to consist partly of nonchord tones ; it is not a chord or harmonic entity in itself.

His Shops Windows can be considered a personal interpretation of Delaunay's Windows, combined with the simultaneity of images found in Italian Futurism.

Only the simultaneity and presence of events are considered.

Next, the work discusses five senses wherein a thing may be considered prior to another, followed by a short section on simultaneity.

So the relativity of simultaneity has to be considered as well.

The United Nations defines the essential features of population and housing censuses as " individual enumeration, universality within a defined territory, simultaneity and defined periodicity ", and recommends that population censuses be taken at least every 10 years.

He declared simultaneity only a convenient convention which depends on the speed of light, whereby the constancy of the speed of light would be a useful postulate for making the laws of nature as simple as possible.

* In criminal law, for a criminal violation to be established, it usually must be shown that there was simultaneity of actus reus and mens rea.

* In physics, see Relativity of simultaneity.

* Relativity of simultaneity: Two events, simultaneous for one observer, may not be simultaneous for another observer if the observers are in relative motion.

The notion of simultaneity depends on the frame of reference ( see relativity of simultaneity ), so switching between frames requires an adjustment in the definition of the present.

If one imagines a present as a ( three-dimensional ) simultaneity plane in Minkowski space, then switching frames results in changing the inclination of the plane.

Blue lines show the planes of simultaneity for the traveling twin during the first leg of the journey ; red lines, during the second leg.

In a sense, during the U-turn the plane of simultaneity jumps from blue to red and very quickly sweeps over a large segment of the world line of the Earth-based twin.

One of the major innovations made by the Salon Cubists, independently of Picasso and Braque, was that of simultaneity, drawing to greater or lesser extent on theories of Henri Poincaré, Ernst Mach, Charles Henry, and Henri Bergson.

With simultaneity, the concept of separate spatial and temporal dimensions was comprehensively challenged.
