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.

On the other hand, the theory of infinite abelian groups is an area of current research.

The theory of adaptive expectations can be applied to all previous periods so that current inflationary expectations equal:

The difficulty in conceiving of or describing an object without also conceiving of or describing its properties is a common justification for bundle theory, especially among current philosophers in the Anglo-American tradition.

Much of the current work in cosmology includes understanding how galaxies form in the context of the Big Bang, understanding the physics of the Universe at earlier and earlier times, and reconciling observations with the basic theory.

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.

For example, in the 19th century, the Sun appeared to be no more than 20 million years old, but the Earth appeared to be no less than 300 million years ( resolved by the discovery of nuclear fusion and radioactivity, and the theory of quantum mechanics ); or current attempts to resolve theoretical differences between quantum mechanics and general relativity.

Darwinism also is used neutrally by historians to differentiate his theory from other evolutionary theories current around the same period.

Arnauld's theory was current until the middle of the nineteenth century.

The source of Einstein's proposal that light was composed of particles ( or could act as particles in some circumstances ) was an experimental anomaly not explained by the wave theory was the photoelectric effect, by which light striking a metal surface ejected electrons from the surface, causing an electric current to flow across an applied voltage.

Notable developments in this century include the work of Georg Ohm, who in 1827 quantified the relationship between the electric current and potential difference in a conductor, Michael Faraday, the discoverer of electromagnetic induction in 1831, and James Clerk Maxwell, who in 1873 published a unified theory of electricity and magnetism in his treatise Electricity and Magnetism.

Ohm's law is a basic law of circuit theory, stating that the current passing through a resistance is directly proportional to the potential difference across it.

EP is closely linked to sociobiology, but there are key differences between them including the emphasis on domain-specific rather than domain-general mechanisms, the relevance of measures of current fitness, the importance of mismatch theory, and psychology rather than behaviour.

General relativity, or the general theory of relativity, is the geometric theory of gravitation published by Albert Einstein in 1916 and the current description of gravitation in modern physics.

However, this conclusion is based on the assumption that current evolutionary theory and intelligent design are the only two valid models to explain life, a false dilemma.

Unlike the short-term business cycle, the long wave of this theory is not accepted by current mainstream economics.

This theory states that new knowledge cannot be told to students, but rather the students ' current knowledge must be challenged.

Many current and recent philosophers — e. g., Daniel Dennett, Willard Van Orman Quine, Donald Davidson, John Rogers Searle, and Jerry Fodor — operate within a broadly physicalist or materialist framework, producing rival accounts of how best to accommodate mind — functionalism, anomalous monism, identity theory, and so on.

He created current algebra in the 1960s as a way of extracting predictions from quark models when the fundamental theory was still murky, which led to model-independent sum rules confirmed by experiment.

Its current name was coined by Charles L. Bouton of Harvard University, who also developed the complete theory of the game in 1901, but the origins of the name were never fully explained.

) also allows a reconciliation of the horizontal demand curve facing each firm according to the theory, with the feeling of businessmen that " contrary to economic theory, sales are by no means unlimited at the current market price " ( Arrow 1959 p. 49 ).

The current set of fundamental fields and their dynamics are summarized in a theory called the Standard Model, therefore particle physics is largely the study of the Standard Model's particle content and its possible extensions.

But Morgan did not leave before he had written a letter to a William Pickman in Salem, Massachusetts, apparently an acquaintance, praising Washington and saying that the slanders propagated about him were `` opposed by the general current of the people to exalt General Gates at the expense of General Washington was injurious to the latter.

`` I am worried about the current meanings of the word funny.

All three are purposely kept small, with a current total enrollment of about two hundred.

The current monthly payroll comes to about $15,000,000.

The current coastline dates back to about 4000 BC.

Lord Dufferin, the current Governor General, expressed early misgivings about a stonemason taking over government.

The current flows at a rate of about four km per hour.

However, there is no consensus, and according to Raymond E. Brown, the current opinion concerning Lukan authorship is " about evenly divided.

Guthrie also saw traces of Acts in Polycarp's letter to the Philippians ( written between 110-140 ) and one letter by Ignatius († about 117 ) and thought that Acts probably was current in Antioch and Smyrna not later than c. 115, and perhaps in Rome as early as c. 96.

What most troubles me now is the instability of the balance, the extreme peril of the current situation, the appalling waste of the arms race ... Each of us has a responsibility to think about this in global terms, with tolerance, trust, and candor, free from ideological dogmatism, parochial interests, or national egotism.

Hipparcos also suggested that Arcturus is a binary star, with the companion about twenty times dimmer than the primary and orbiting close enough to be at the very limits of our current ability to make it out.

The standard example is the stock of a company, undervalued in the stock market, which is about to be the object of a takeover bid ; the price of the takeover will more truly reflect the value of the company, giving a large profit to those who bought at the current price — if the merger goes through as predicted.

Based on this definition, the drain efficiency cannot exceed 25 % for a class A amplifier that is supplied drain bias current through resistors ( because RF signal has its zero level at about 50 % of the input DC ).

It generates about 90 % of export revenues, making the country particularly vulnerable to terms of trade shocks: the current account deficit in 2007 ran at 15 % of GDP.

In 1880, the French government awarded Bell the Volta Prize of 50, 000 francs ( approximately US $ 10, 000 at that time, about $ in current dollars ) for the invention of the telephone, which he used to found the Volta Laboratory, along with Sumner Tainter and Bell's cousin Chichester Bell.

When the cube is centered, the player about to roll may propose that the game be played for twice the current stakes.

No large earthquake has occurred on the Hayward Fault near Berkeley in historic times ( except possibly in 1836 ), but seismologists warn about the geologic record of large temblors several times in the deeper past, and their current assessment is that a quake of 6. 5 or greater is imminent, sometime within the next 30 years.

The Zebra Fish Information Network provides up-to-date information about current known wild-type ( WT ) strains of D. rerio, some of which are listed below.

Of the current total, only about 50 percent of the roads and highways were covered with asphalt and were in good condition ; about 50 percent of the roads were made of crushed stone, gravel, or improved earth ; and the remaining approximately 30 percent were unimproved earth or were little more than tracks.

Even with no external electric field applied, these electrons move about randomly due to thermal energy but, on average, there is zero net current within the metal.

The first known reference to the site of the current city of Chicago as " Checagou " was by Robert de LaSalle around 1679 in a memoir written about the time.

For example, sales representatives need to know about current issues and relevant marketing promotions before attempting to cross-sell to a specific client.
