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

*: 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.

The calculation of ephemerides also requires a consideration of the effects of general relativity.

The 1976 definition of the astronomical unit was incomplete, in particular because it does not specify the frame of reference in which time is to be measured, but proved practical for the calculation of ephemerides: a fuller definition that is consistent with general relativity was proposed, and " vigorous debate " ensued until in August 2012 the International Astronomical Union adopted the current definition of 1 astronomical unit = 149597870700 meters.

The theory of special relativity predicts that any such device would allow communication from the future to the past, which raises problems of causality, unless the device used general relativistic curved spacetimes as an integral part.

The framework for the Big Bang model relies on Albert Einstein's general relativity and on simplifying assumptions such as homogeneity and isotropy of space.

Extrapolation of the expansion of the Universe backwards in time using general relativity yields an infinite density and temperature at a finite time in the past.

This singularity signals the breakdown of general relativity.

Dark energy in its simplest formulation takes the form of the cosmological constant term in Einstein's field equations of general relativity, but its composition and mechanism are unknown and, more generally, the details of its equation of state and relationship with the Standard Model of particle physics continue to be investigated both observationally and theoretically.

Also, general relativity has passed stringent tests on the scale of the Solar System and binary stars while extrapolation to cosmological scales has been validated by the empirical successes of various aspects of the Big Bang theory.

Ten years later, Alexander Friedmann, a Russian cosmologist and mathematician, derived the Friedmann equations from Albert Einstein's equations of general relativity, showing that the Universe might be expanding in contrast to the static Universe model advocated by Einstein at that time.

The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole.

The first modern solution of general relativity that would characterize a black hole was found by Karl Schwarzschild in 1916, although its interpretation as a region of space from which nothing can escape was not fully appreciated for another four decades.

Long considered a mathematical curiosity, it was during the 1960s that theoretical work showed black holes were a generic prediction of general relativity.

In 1915, Albert Einstein developed his theory of general relativity, having earlier shown that gravity does influence light's motion.

These results came at the beginning of the golden age of general relativity, which was marked by general relativity and black holes becoming mainstream subjects of research.

Physical cosmology, as it is now understood, began with the twentieth century development of Albert Einstein's general theory of relativity and better astronomical observations of extremely distant objects.

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

In 1916, Albert Einstein published his theory of general relativity, which provided a unified description of gravity as a geometric property of space and time.

It was later realized that Einstein's model was just one of a larger set of possibilities, all of which were consistent with general relativity and the cosmological principle.

The cosmological solutions of general relativity were found by Alexander Friedmann in the early 1920s.

One consequence of this is that in standard general relativity, the universe began with a singularity, as demonstrated by Stephen Hawking and Roger Penrose in the 1960s.

The general acceptance of the idea of governmental ( i.e., societal ) responsibility for the economic well-being of the American people is surely one of the two most significant watersheds in American constitutional history.

I was having lunch not long ago ( apologies to N. V. Peale ) with three distinguished historians ( one specializing in the European Middle Ages, one in American history, and one in the Far East ), and I asked them if they could name instances where the general mores had been radically changed with `` deliberate speed, majestic instancy '' ( Francis Thompson's words for the Hound Of Heaven's Pursuit ) by judicial fiat.

The riotous onrush of industrialism after the War for Southern Independence and the general secular drift to the Religion of Humanity, however, prepared the way for a reception of the French Revolution's socialistic offspring of one sort of another.

I had long since begun to lose my general innocence when I lost my trust in you, but this special innocence I lost before ever I loved, through my discovery that one could tremble with desire and even experience a flaming delight that had nothing, nothing whatever to do with friendship or liking, let alone with love.

Its truth is illustrated by the skill, sensitivity, and general expertise of the English professor with whom one attends the theatre.

In a symposium and general exploration of the field of Personal Perception and Interpersonal Behavior the discussion does not touch upon this aspect of the subject, with one possible exception ; ;

But, in general, we may argue that the student can direct the primary emphasis of his attention toward one or the other.

Out of Saxony rode the Prince of Anhalt-Bernburg, one of the Czarina's cousins and a lieutenant general in her armies, a frank, sensitive, popular soldier whose kindnesses Littlepage would `` always recall with the sincerest gratitude ''.

But there was one thing that he had to stress, and that was that the contribution to the general church expenses, the dollar money, had been seriously falling behind in this church, and that must be looked after immediately.

This problem of fair and equitable assessment of value is a difficult one to solve in that the determination of fair valuation is dependent on local assessors, who in general are non-professional and part-time personnel taking an individualistic approach to the problem.

and ( C ) to finance, for not more than three years beyond the end of said period, such activities as are required to correlate, coordinate, and round out the results of studies and research undertaken pursuant to this Act: Provided, That funds available in any one year for research and development may, subject to the approval of the Secretary of State to assure that such activities are consistent with the foreign policy objectives of the United States, be expended in cooperation with public or private agencies in foreign countries in the development of processes useful to the program in the United States: And provided further, That every such contract or agreement made with any public or private agency in a foreign country shall contain provisions effective to insure that the results or information developed in connection therewith shall be available without cost to the United States for the use of the United States throughout the world and for the use of the general public within the United States.

While there should be no general age limit or restriction to one sex, there will be particular projects requiring special maturity and some open only to men or to women.

While this may well be true in general, I believe it is also important to keep in mind that some recent developments suggest that over the next year or so military electronics may be one of the most strongly growing areas in an economy which is not expanding rapidly in other directions.

It seems reasonable that if general nuclear war is not to be one cataclysmic act of burning each other's citizens to cinders, we must have a manned strategic force of long-endurance aircraft capable of going into China or Russia to find and destroy their strategic forces which continued to threaten us.

Some general things to look for in a site, if you haven't already bought one, are accessibility, water drainage, and orientation.

By that, one feels that magnetic forces are as general as electrical forces.

This can only be for one of two reasons: either the two are quite different and will require totally different theory ( and hence techniques ), or our existing theories are insufficiently general.

`` We were brought up that way '' was one statement which won general assent.

`` This is one of the major items in the Fulton County general assistance program '', the jury said, but the State Welfare Department `` has seen fit to distribute these funds through the welfare departments of all the counties in the state with the exception of Fulton County, which receives none of this money.

In spite of the increase in numbers and prestige brought about by the conversions of Newman and other Tractarians of the 1840's and 1850's, the Catholic segment of England one hundred years ago was a very small one ( four per cent, or 800,000 ) which did not enjoy a gracious hearing from the general public.

* branched ( general formula, n > 3 ) wherein the carbon backbone splits off in one or more directions

An alphabet is a standard set of letters ( basic written symbols or graphemes ) which is used to write one or more languages based on the general principle that the letters represent phonemes ( basic significant sounds ) of the spoken language.
