Negation (other)
Negation is a connective in logic and an operation computing that maps true to false and false to true. Negation may also refer to: * Negation (linguistics), a grammatical operation by which a proposition is replaced by one that states the opposite, as by the addition of ''not'' * ''Negation'' (comics), a CrossGen comic * ''The Negation'', a 2004 album by the Polish metal band Decapitated * Negationism, an illegitimate historical revisionist process that minimizes, denies or ignores essential facts * Negation (poem), a 1918 poem by Wallace Stevens * Negation (algebra), negation proper in various algebraic structures * Negation (arithmetic), the operation in mathematics that maps positive numbers to negative numbers and vice versa, also known as sign change and opposite number ** Negative number ** Minus sign See also * Negative (other) Negative may refer to: Science and mathematics * Negative number * Negative mass * Negative energy * Negative charge, one of t ...

Negation
In logic, negation, also called the logical complement, is an operation that takes a proposition P to another proposition "not P", written \neg P, \mathord P or \overline. It is interpreted intuitively as being true when P is false, and false when P is true. Negation is thus a unary logical connective. It may be applied as an operation on notions, propositions, truth values, or semantic values more generally. In classical logic, negation is normally identified with the truth function that takes ''truth'' to ''falsity'' (and vice versa). In intuitionistic logic, according to the Brouwer–Heyting–Kolmogorov interpretation, the negation of a proposition P is the proposition whose proofs are the refutations of P. Definition ''Classical negation'' is an operation on one logical value, typically the value of a proposition, that produces a value of ''true'' when its operand is false, and a value of ''false'' when its operand is true. Thus if statement is true, then \neg P (pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Negation (linguistics)
In linguistics and grammar, affirmation (abbreviated ) and negation () are ways in which grammar encodes positive and negative polarity into verb phrases, clauses, or other utterances. An affirmative (positive) form is used to express the validity or truth of a basic assertion, while a negative form expresses its falsity. For example, the affirmative sentence "Jane is here" asserts that it is true that Jane is currently located near the speaker. Conversely, the negative sentence "Jane is not here" asserts that it is not true that Jane is currently located near the speaker. The grammatical category associated with affirmatives and negatives is called polarity. This means that a clause, sentence, verb phrase, etc. may be said to have either affirmative or negative polarity (its polarity may be either affirmative or negative). Affirmative is typically the unmarked polarity, whereas a negative statement is marked in some way. Negative polarity can be indicated by negating words or pa ...

Negation (comics)
''Negation'' was a comic book series published from CrossGen. Tony Bedard was the writer for the entire run. Paul Pelletier was the artist for most of the issues, with an occasional fill-in artist on some issues. The series started with the ''Negation Prequel'' in late 2001. 27 regular issues followed the prequel. The series concerned a group of different alien races that had been taken prisoner and brought to the Negation universe. A number of the prisoners had innate superhuman powers while many, like Obregon Kaine, were ordinary humans. His tactical military experience made him able to lead the prisoners. He masterminded the plan that allowed a number of his fellow prisoners to escape the prison planet all of them were being held in. The series details the adventures which Kaine and the rest had in Negation space. The series ended with issue #27. CrossGen tried to wrap up all the dangling storylines in the '' Negation: War'' mini-series. CrossGen had to declare bankruptcy before ...

The Negation
''The Negation'' is the third studio album by the death metal band Decapitated from Poland. It was released on 9 March 2004, through Earache Records. It is Decapitated's final album to feature vocalist Wojciech "Sauron" Wąsowicz. Critical reception After its release, ''The Negation'' received mixed reviews from music critics. William York of AllMusic praised the production saying ..is far better than on most of the big-name death metal albums released in the early 2000s. It's clear and full sounding, yet without being overly slick or digitally sanitized." While Jill Mikkelson of Exclaim! praised songwriting "All ten songs are delivered with debilitating momentum and quirky time changes, humiliating most contemporary metal outfits. Slower grooves paired with bludgeoning drumming create a crisp but exceptionally intense sound that has developed into their own."

Negationism
Historical negationism, also called denialism, is falsification or distortion of the historical record. It should not be conflated with '' historical revisionism'', a broader term that extends to newly evidenced, fairly reasoned academic reinterpretations of history."The two leading critical exposés of Holocaust denial in the United States were written by historians Deborah Lipstadt (1993) and Michael Shermer and Alex Grobman (2000). These scholars make a distinction between historical revisionism and denial. Revisionism, in their view, entails a refinement of existing knowledge about an historical event, not a denial of the event itself, that comes through the examination of new empirical evidence or a re-examination or reinterpretation of existing evidence. Legitimate historical revisionism acknowledges a 'certain body of irrefutable evidence' or a 'convergence of evidence' that suggest that an event – like the black plague, American slavery, or the Holocaust – did in fact ...

Negation (poem)
"Negation" is a poem from Wallace Stevens's first book of poetry, ''Harmonium''. It was first published in 1918, so it is in the public domain.Bates, p. 133 This poem was Section VII of the poem—sequence "Lettres d'un Soldat" (1918). It was extracted as "Negation" for inclusion in the second edition of ''Harmonium''. It may reflect Stevens's reading of ''Thus Spoke Zarathustra'', according to Bates. The poem's image of God as bungling potter recalls Zarathustra's dialogue with the last pope, in which God is similarly characterized. Another ''Harmonium'' poem that clearly reflects Stevens's reading of Nietzsche is " The Surprises of the Superhuman", which was also extracted from "Lettres d'un Soldat" for inclusion in the second edition. The poem is notable for its arch wit and the anti-poetical salutation, "Hi!", rather than as a solution to the problem of evil The problem of evil is the question of how to reconcile the existence of evil and suffering with an omnipote ...

Negation (arithmetic)
In mathematics, the additive inverse of a number is the number that, when added to , yields zero. This number is also known as the opposite (number), sign change, and negation. For a real number, it reverses its sign: the additive inverse (opposite number) of a positive number is negative, and the additive inverse of a negative number is positive. Zero is the additive inverse of itself. The additive inverse of is denoted by unary minus: (see also below). For example, the additive inverse of 7 is −7, because , and the additive inverse of −0.3 is 0.3, because . Similarly, the additive inverse of is which can be simplified to . The additive inverse of is , because . The additive inverse is defined as its inverse element under the binary operation of addition (see also below), which allows a broad generalization to mathematical objects other than numbers. As for any inverse operation, double additive inverse has no net effect: . Common examples For a number (and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Negative Number
In mathematics, a negative number represents an opposite. In the real number system, a negative number is a number that is less than zero. Negative numbers are often used to represent the magnitude of a loss or deficiency. A debt that is owed may be thought of as a negative asset. If a quantity, such as the charge on an electron, may have either of two opposite senses, then one may choose to distinguish between those senses—perhaps arbitrarily—as ''positive'' and ''negative''. Negative numbers are used to describe values on a scale that goes below zero, such as the Celsius and Fahrenheit scales for temperature. The laws of arithmetic for negative numbers ensure that the common-sense idea of an opposite is reflected in arithmetic. For example, −(−3) = 3 because the opposite of an opposite is the original value. Negative numbers are usually written with a minus sign in front. For example, −3 represents a negative quantity with a magnitude of three, and is pronounced "min ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minus Sign
The plus and minus signs, and , are mathematical symbols used to represent the notions of positive and negative, respectively. In addition, represents the operation of addition, which results in a sum, while represents subtraction, resulting in a difference. Their use has been extended to many other meanings, more or less analogous. ''Plus'' and ''minus'' are Latin terms meaning "more" and "less", respectively. History Though the signs now seem as familiar as the alphabet or the Hindu-Arabic numerals, they are not of great antiquity. The Egyptian hieroglyphic sign for addition, for example, resembled a pair of legs walking in the direction in which the text was written (Egyptian could be written either from right to left or left to right), with the reverse sign indicating subtraction: Nicole Oresme's manuscripts from the 14th century show what may be one of the earliest uses of as a sign for plus. In early 15th century Europe, the letters "P" and "M" were generally u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
