Closely linked to these cohomology theories, he originated topos theory as a generalisation of topology ( relevant also in categorical logic ).

Areas relevant to cosmology include particle physics experiments and theory, including astrophysics, general relativity, and plasma physics.

Although Story was highly intelligent and familiar with all the relevant English precedents, he merely summarized them in a confused fashion because he " could not conceive of a modern function or a coherent theory for representative litigation: why?

According to the theory that knowledge is justified true belief, in order to know that a given proposition is true, one must not only believe the relevant true proposition, but one must also have a good reason for doing so.

The relevant theoretical concepts may purportedly be part of the structure of the human mind ( as in Kant's theory of transcendental idealism ), or they may be said to exist independently of the mind ( as in Plato's theory of Forms ).

Although most of the relevant tissues and endocrine glands had been identified by early anatomists, a more humoral approach to understanding biological function and disease was favoured by the ancient Greek and Roman thinkers such as Aristotle, Hippocrates, Lucretius, Celsus, and Galen, according to Freeman et al., and these theories held sway until the advent of germ theory, physiology, and organ basis of pathology in the 19th century.

Even circuit theory may not be relevant to a person designing telecommunication systems that use off-the-shelf components.

If confirmed, this would imply special relativity is an approximation to a more general theory, but since the relevant comparison would ( by definition ) be outside the observable universe, it is difficult to imagine ( much less construct ) experiments to test this hypothesis.

A 2012 book titled The Julian Jaynes Collection gathers together many of the lectures and articles by Jaynes relevant to his theory ( including some that were previously unpublished ), along with interviews and question and answer sessions where Jaynes addresses misconceptions about the theory and extends the theory into new areas.

He rejected the theory of class struggle and the Marxist concern with labor, instead claiming, according to Leszek Kołakowski, that since " all questions of material existence have been solved, moral commands and prohibitions are no longer relevant.

The results of the research showed that after 12 sessions the rhesus monkeys acquired a fear to the evolutionary relevant stimuli and not to the evolutionary irrelevant stimuli ; furthermore, the experiment also revealed that when they exposed monkeys to other monkeys that interacted with snakes without showing fear, this group did not acquire the fear which supports the theory of vicarious conditioning through modeling.

To a certain extent, general relativity can be seen to be a relational theory, in which the only physically relevant information is the relationship between different events in space-time.

That is, strict rational choice theory would not see a criminal's self-punishment by inner feelings of remorse, guilt, or shame as relevant to determining the costs of committing a crime.

This along with the beginning of two can be taken to be the relevant parts of Wittgenstein's metaphysical view that he will use to support his picture theory of language.

Thus, although the current standard model of particle physics " in principle " predicts all known non-gravitational phenomena, in practice only a few quantitative results have been derived from the full theory ( e. g., the masses of some of the simplest hadrons ), and these results ( especially the particle masses which are most relevant for low-energy physics ) are less accurate than existing experimental measurements.

Nevertheless, more recently, with the rise of the density functional theory and other methods like molecular mechanics, the range of application has been extended to chemical systems which are relevant to other fields of chemistry and physics like biochemistry, condensed matter physics, nanotechnology or molecular biology.

However, both moral and natural goods are equally relevant to goodness and value theory, which is more general in scope.

This theory assumes a general deficit in old age in the ability to inhibit irrelevant, or no-longer relevant, information.

Burke goes on to describe symbols as also being derived from Sigmund Freud's work on condensation and displacement further stating that they are not just relevant to the theory of dreams, but also to " normal symbol systems ".

Nevertheless many other considerations of pitch are relevant to the music, its theory and its structure, such as the complex system of Rāgas, which combines both melodic and modal considerations and codifications within it.

In some fields, noise means unwanted information or data that is not relevant to the hypothesis or theory being investigated or tested.

Of course it had always been of European origin in fact, but it had maintained a universal outlook under the natural law theory.

Other theories of origin are compatible with the formulaic theory: Beowulf may contain a design for terror, and The Iliad may have a vast hysteron-proteron pattern answering to a ceramic pattern produced during the Geometric Period in pottery.

The discovery and confirmation of the cosmic microwave background radiation in 1964 secured the Big Bang as the best theory of the origin and evolution of the cosmos.

The BCS theory, however, requires only that the potential be attractive, regardless of its origin.

However, the results of BCS theory do not depend on the origin of the attractive interaction.

One theory is the origin of such terminology is from the Mayan temple Chichen Itza in the Yucatan Peninsula, a ruin of an ancient MesoAmerican civilization about 1, 500 years ago.

Unlike the related gray wolf, which is Eurasian in origin, evolutionary theory suggests the coyote evolved in North America during the Pleistocene epoch 1. 81 million years ago ( mya ) alongside the dire wolf.

The Valentinian theory elaborates that from Achamoth ( he káta sophía or lower wisdom ) three kinds of substance take their origin, the spiritual ( pneumatikoí ), the animal ( psychikoí ) and the material ( hylikoí ).

These modern organisms with endosymbiotic relationships with aerobic bacteria have verified the endosymbiotic theory, which explains the origin of mitochondria and chloroplasts from bacteria.

This migration and origin theory is usually referred to as the recent single origin or Out of Africa theory.

This Germanic origin theory was also shared by William Stubbs in the nineteenth century.

Another theory by Alauddin Samarrai suggests an Arabic origin, from fuyū ( the plural of fay, which literally means " the returned ", and was used especially for ' land that has been conquered from enemies that did not fight ').

Samarrai, however, also advises to handle this theory with care, as Medieval and Early Modern Muslim scribes often used etymologically " fanciful roots " in order claim the most outlandish things to be of Arabian or Muslim origin.

Cantor's work between 1874 and 1884 is the origin of set theory.

The fusion of the ideas coming from mathematics with those coming from chemistry is at the origin of a part of the standard terminology of graph theory.

The works of Ramsey on colorations and more specially the results obtained by Turán in 1941 was at the origin of another branch of graph theory, extremal graph theory.

Harkins believes the most credible theory of the term's origin is that it derives from the linkage of two older Scottish expressions, " hill-folk " and " billie " which was a synonym for " fellow ", similar to " guy " or " bloke ".

Following criticism, especially the arguments from Richard Kirwan who thought Hutton's ideas were atheistic and not logical, Hutton published a two volume version of his theory in 1795, consisting of the 1788 version of his theory ( with slight additions ) along with a lot of material drawn from shorter papers Hutton already had to hand on various subjects such as the origin of granite.

Locke's theory of mind is often cited as the origin of modern conceptions of identity and the self, figuring prominently in the work of later philosophers such as Hume, Rousseau and Kant.

Dr. Bonnor begins with a discussion of the relativistic theories of the universe, based on the general theory of relativity.

Dr. Lyttleton backs the theory that we live in an electric universe and this theory starts with the behavior of protons and electrons.

In classical Greece, Anaxagoras asserted that a divine reason ( mind ) gave order to the seeds of the universe, and Plato extended the Greek belief of ideal forms to his metaphysical theory of forms ( ideai: ideas ).

Sometimes slightly stronger theories such as Morse-Kelley set theory or set theory with a strongly inaccessible cardinal allowing the use of a Grothendieck universe are used, but in fact most mathematicians can actually prove all they need in systems weaker than ZFC, such as second-order arithmetic.

Thus, the Big Bang theory cannot and does not provide any explanation for such an initial condition ; rather, it describes and explains the general evolution of the universe going forward from that point on.

Inflation and baryogenesis remain more speculative features of current Big Bang models: they explain important features of the early universe, but could be replaced by alternative ideas without affecting the rest of the theory.

At the time, Einstein believed in a static universe, but found that his original formulation of the theory did not permit it.

There is no definite or clear way to define the total energy of the universe due to the most widely accepted theory of gravity, general relativity.

Both the problems of baryogenesis and cosmic inflation are very closely related to particle physics, and their resolution might come from high energy theory and experiment, rather than through observations of the universe.

Big Bang Nucleosynthesis is the theory of the formation of the elements in the early universe.

It was used for many years as a probe of physics at the time of the Big Bang, as the theory of Big Bang nucleosynthesis connects the abundances of primordial light elements with the features of the early universe.

Cosmological perturbation theory, which describes the evolution of slight inhomogeneities in the early universe, has allowed cosmologists to precisely calculate the angular power spectrum of the radiation, and it has been measured by the recent satellite experiments ( COBE and WMAP ) and many ground and balloon-based experiments ( such as Degree Angular Scale Interferometer, Cosmic Background Imager, and Boomerang ).

* the equivalence principle, whether or not Einstein's general theory of relativity is the correct theory of gravitation, and if the fundamental laws of physics are the same everywhere in the universe.

* Doughnut theory of the universe

His theory attempted to explain the universe in terms of basic forces in nature: the complementary agents of yin ( dark, cold, female, negative ) and yang ( light, hot, male, positive ) and the Five Elements or Five Phases ( water, fire, wood, metal, and earth ).

Research on these geometries led to, among other things, Einstein's theory of general relativity, which describes the universe as non-Euclidean.

The theory is said to assume many aspects of how the universe came to be without scientific analysis, and assumes a monotheistic religious outlook.

The arguments of the lattice theory operations meet and join are elements of some universe A.

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.

In string theory, Eric G. Gimon and Petr Hořava have argued that in a supersymmetric five-dimensional Gödel universe, quantum corrections to general relativity effectively cut off regions of spacetime with causality-violating closed timelike curves.
