Relativity   Listen
noun
relativity  n.  
1.
The state of being relative; as, the relativity of a subject.
2.
One of two theories (also called theory of relativity) proposed by Albert Einstein, the special theory of relativity, or the general theory of relativity. The special theory of relativity or special relativity is based on the proposition that the speed of light is a constant no matter how observed, and is independent of the motion of the observer. From this follows several principles, such as the increase of mass with velocity (which has been confirmed: see relativistic mass equation) and the impossibility of acceleration to a speed greater than that of light; the equivalence of mass and energy, expressed by the famous equation E = mc^(2); and time dilation, which is the apparent slowing of a clock in a system, as observed by an observer in a system moving relative to the clock. The general theory of relativity is based on the proposition that there is no physical difference between gravitational force and the force produced by acceleration. From this follow several results, of which the bending of light rays in a gravitational field and the equivalence of the inertial and gravitational masses have been verified. The possible existence of black holes (believed by many astronomers to have been adequately proven) is another consequence of the theory.

... Hillbridge circle, where rapture ran the highest, he was accepted on what was at best but an indirect valuation; and now and then she had a frightened doubt as to the independence of her own convictions. That innate sense of relativity which even East Onondaigua had not been able to check in Claudia Day had been fostered in Mrs. Keniston by the artistic absolutism of Hillbridge, and she often wondered that her husband remained so uncritical of the quality of admiration accorded him. Her husband's uncritical attitude ...

... always new wonderful mornings and still cool twilights at the end of day; and ever a thousand interests claimed him, and his interests were shared by her. More thoroughly than he knew, had he come to a comprehension of the relativity of things. In this new game he played he found in little things all the intensities of gratification and desire that he had found in the frenzied big things when he was a power and rocked half a continent with the fury of the blows he struck. ...

... found that presently he himself could handle the facts of life with the light dexterity which had so amazed him; but through it all he preserved (as he could see that those about him did not) his sense of the relativity of things. He perceived, always, the dependence of the facts of life upon the ideas underlying them, and thrusting them forward as manifestations or utterances. With his undissipated energy, his curious frugality in the matter of self-revelation, and his instinctive ...

... the 'wormhole' singularities hypothesized in some versions of General Relativity theory] 1. obs. A location in a monitor which contains the address of a routine, with the specific intent of making it easy to substitute a different routine. This term is now obsolescent; modern operating systems use clusters of wormholes extensively (for modularization of I/O handling ...

... Russell and Mr. Moore, even as it stands; and one trembles to think what it may become in the mouths of their disciples. Intolerance itself is a form of egoism, and to condemn egoism intolerantly is to share it. I cannot help thinking that a consciousness of the relativity of values, if it became prevalent, would tend to render people more truly social than would a belief that things have intrinsic and unchangeable values, no matter what the attitude of any one to them may be. If ...

... phenomenon of the opposition to Anarchism is that it brings to light the relation between so-called intelligence and ignorance. And yet this is not so very strange when we consider the relativity of all things. The ignorant mass has in its favor that it makes no pretense of knowledge or tolerance. Acting, as it always does, by mere impulse, its reasons are like those of a child. "Why?" "Because." Yet the opposition of the uneducated to Anarchism deserves the same consideration as that ...

... prove that the phenomena represent objects, or find out what the relation of phenomena to objects is. There is no criterion to tell us which one is true of all the different representations of the same object, and of all the varieties of sensation that arise through the many phases of relativity of the conditions which control the character ...

... purchasing power. Since the armistice prices have moved upwards and downwards with unprecedented violence; and it would be very rash to prophesy the precise level at which they will ultimately settle (using that word with considerable relativity). But, for reasons for which the reader is referred to Volume II in this series, it is safe enough to say that the general level of post-war will greatly exceed that of pre-war prices. Now this will apply not only to consumers' goods like milk and clothes, or to raw ...

... rationalism and much so-called liberal Christianity, Schleiermacher contended that Christianity is not a new set of propositions periodically brought up to date and proclaimed as if these alone were true.

... abstraction. This abstraction is the far-off heaven on which the eye of the mind is fixed in fond amazement. The unity of truth, the consistency of the warring elements of the world, the enthusiasm for knowledge when first beaming upon mankind, the relativity of ideas to the human mind, and of the human mind to ideas, the faith in the invisible, the adoration of the eternal nature, are all included, consciously or unconsciously, in Plato's doctrine ...
