This, of course, results from the non-systematic, ' cellular ' character of Ptolemaic theory.

The theory behind this is, of course, fundamentalist in character.

Of course, the current state of technology at any given time can put limitations on what can be achieved experimentally and theoretically so it may take considerable time for theory to be refined.

Moreover, some of Dutton's categories seem too broad: a physicist might entertain hypothetical worlds in his / her imagination in the course of formulating a theory.

It is also worth noting that part of the original motivation of the search for stellar parallax was to test the Copernican theory that the Earth revolves around the Sun, but of course the existence of aberration also establishes the truth of that theory.

This is totally spurious, since no matter who measured first the other will measure the opposite spin despite the fact that ( in theory ) the other has a 50 % ' probability ' ( 50: 50 chance ) of measuring the same spin, unless data about the first spin measurement has somehow passed faster than light ( of course TI gets around the light speed limit by having information travel backwards in time instead ).

In the course of studying the problem, Church and his student Stephen Kleene introduced the notion of λ-definable functions, and they were able to prove that several large classes of functions frequently encountered in number theory were λ-definable.

Students of control engineering may start with a linear control system course dealing with the time and complex-s domain, which requires a thorough background in elementary mathematics and Laplace transform ( called classical control theory ).

Hilbert's work had started logic on this course of clarification ; the need to understand Gödel's work then led to the development of recursion theory and then mathematical logic as an autonomous discipline in the 1930s.

Utilitarianism is a hedonistic ethical theory that argues the proper course of action is one that maximizes overall " happiness ".

A theory of electromagnetism, known as classical electromagnetism, was developed by various physicists over the course of the 19th century, culminating in the work of James Clerk Maxwell, who unified the preceding developments into a single theory and discovered the electromagnetic nature of light.

It is an ethical theory holding that the proper course of action is the one that maximizes the overall " good " of the society.

Any undergraduate course in trade theory includes a presentation of Ricardo's example of a two-commodity, two-country model.

* Fundamentals of Flight, Richard S. Shevell, Prentice-Hall International Editions, ISBN 0-13-332917-8 – This book is primarily intended as a text for a one semester undergraduate course in mechanical or aeronautical engineering, although its sections on theory of flight are understandable with a passing knowledge of calculus and physics.

A concurrent theory would be that supply and demand would cause media to attain a neutral balance because consumers would of course gravitate towards the media they agreed with.

Of course this theorem is considered irrelevant by economists who do not believe that general equilibrium theory correctly predicts the functioning of market economies ; but it is given great importance by neoclassical economists and it is the theoretical reason given by them for combating monopolies and for antitrust legislation.

" His theory was that an underground water course may flow under " haunted " locations and that after heavy rainfall the stream could cause structural movement of the property, possibly causing the house to vibrate and move objects.

" It may be utilized only when the circumstances of the incident, without further proof, are such that, in the ordinary course of events, the incident could not have happened except on the theory of negligence ..."

Frisch also started lecturing a course on production theory, introducing a mathematization of the subject.

Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection.

The Rusk belief in balanced defense, replacing the Dulles theory of massive retaliation, removes a grave danger that has existed.

Falling somewhere in a category between Einstein's theory and sand fleas -- difficult to see but undeniably there, nevertheless -- is the tropical green `` city '' of Islandia, a string of offshore islands that has almost no residents, limited access and an unlimited future.

Nevertheless, the theory that the determining influence of the hypothalamic balance has a profound influence on the clinical behavior of neuropsychiatric patients has not yet been tested on an adequate number of patients.

We should expect that general phonologic theory should be as adequate for tone as for consonants and vowels, but it has not been.

Social theory has no more right to expect results from meaningless questions, than physics has the right to expect a theological solution to the wave-particle controversy.

This theory has been put so clearly and precisely that it deserves criticism of the same kind, and this I will do my best to supply.

-- On the basis of a differentiability assumption in function space, it is possible to prove that, for materials having the property that the stress is given by a functional of the history of the deformation gradients, the classical theory of infinitesimal viscoelasticity is valid when the deformation has been infinitesimal for all times in the past.

-- The theory of elasticity of Gaussian networks has been developed on a more general basis and the equations of state relating variables of pressure, volume, temperature, stress and strain have been precisely formulated.

Modern physics has developed the theory that all matter consists of minute waves of energy.

Group selection theory has criticized by many other evolutionary scientists.

Connes has applied his work in areas of mathematics and theoretical physics, including number theory, differential geometry and particle physics.

Tylor also theorized about the origins of religious beliefs in human beings, proposing a theory of animism as the earliest stage, and noting that " religion " has many components, of which he believed the most important to be belief in supernatural beings ( as opposed to moral systems, cosmology, etc .).

Later in the 1960s and 1970s, Edmund Leach and his students Mary Douglas and Nur Yalman, among others, introduced French structuralism in the style of Lévi-Strauss ; while British anthropology has continued to emphasize social organization and economics over purely symbolic or literary topics, differences among British, French, and American sociocultural anthropologies have diminished with increasing dialogue and borrowing of both theory and methods.

Anthropology has been used in Britain to provide an alternative explanation for the Financial crisis of 2007 – 2010 to the technical explanations rooted in economic and political theory.

Brønsted-Lowry acid-base theory has several advantages over Arrhenius theory.

*: The article on Whorf states " Drawing on Nietzsche's ideas of perspectivism Alfred Korzybski developed the theory of general semantics which has been compared to Whorf's notions of linguistic relativity.

A common theory about the building is that the rounded feature to the left of centre, terminating at the top in a turret and cross, represents the lance of Saint George ( patron saint of Catalonia, Gaudi's home ), which has been plunged into the back of the dragon.

It occupies a central place in modern mathematics and has multiple conceptual connections with such diverse fields as complex analysis, topology and number theory.

Within algebraic geometry itself, his theory of schemes has become the universally accepted language for all further technical work.

His construction of new cohomology theories has left deep consequences for algebraic number theory, algebraic topology, and representation theory.

His creation of topos theory has had an impact on set theory and logic.
