Abstract And Concrete Wikipedia

Abstract and concrete - Wikipedia.

In metaphysics, the distinction between abstract and concrete refers to a divide between two types of entities. Many philosophers hold that this difference has fundamental metaphysical significance. Examples of concrete objects include plants, human beings and planets while things like numbers, sets and propositions are abstract objects. There is no general consensus as to ....

Abstract data type - Wikipedia.

In computer science, an abstract data type (ADT) is a mathematical model for data types.An abstract data type is defined by its behavior from the point of view of a user, of the data, specifically in terms of possible values, possible operations on data of this type, and the behavior of these operations.This mathematical model contrasts with data structures, which are ....


Object (computer science) - Wikipedia.

The object-oriented approach is an evolution of good design practices that go back to the very beginning of computer programming. Object-orientation is simply the logical extension of older techniques such as structured programming and abstract data types. An object is an abstract data type with the addition of polymorphism and inheritance..


Determinant - Wikipedia.

In mathematics, the determinant is a scalar value that is a function of the entries of a square matrix.It allows characterizing some properties of the matrix and the linear map represented by the matrix. In particular, the determinant is nonzero if and only if the matrix is invertible and the linear map represented by the matrix is an isomorphism.The determinant of a product of ....


Absolute music - Wikipedia.

Absolute music (sometimes abstract music) is music that is not explicitly 'about' anything; in contrast to program music, it is non-representational. The idea of absolute music developed at the end of the 18th century in the writings of authors of early German Romanticism, such as Wilhelm Heinrich Wackenroder, Ludwig Tieck and E. T. A. Hoffmann but the term was not ....


Zero-knowledge proof - Wikipedia.

In cryptography, a zero-knowledge proof or zero-knowledge protocol is a method by which one party (the prover) can prove to another party (the verifier) that a given statement is true while the prover avoids conveying any additional information apart from the fact that the statement is indeed true. The essence of zero-knowledge proofs is that it is trivial to prove that one possesses ....


Matrix (mathematics) - Wikipedia.

is a matrix with two rows and three columns. This is often referred to as a "two by three matrix", a "2x3-matrix", or a matrix of dimension 2x3.Without further specifications, matrices represent linear maps, and allow explicit computations in linear algebra.Therefore, the study of matrices is a large part of linear algebra, and most properties and operations of abstract linear algebra can be ....


Abstract art - Wikipedia.

Abstract art uses visual language of shape, form, color and line to create a composition which may exist with a degree of independence from visual references in the world. Western art had been, from the Renaissance up to the middle of the 19th century, underpinned by the logic of perspective and an attempt to reproduce an illusion of visible reality. By the end of the 19th ....


Factory method pattern - Wikipedia.

In the above code you can see the creation of one interface called IPerson and two implementations called Villager and CityPerson.Based on the type passed into the Factory object, we are returning the original concrete object as the interface IPerson.. A factory method is just an addition to Factory class. It creates the object of the class through interfaces but on the other ....


Data structure - Wikipedia.

In computer science, a data structure is a data organization, management, and storage format that is usually chosen for efficient access to data. More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the data, i.e., it is an algebraic structure about data.


Symbol - Wikipedia.

A symbol is a mark, sign, or word that indicates, signifies, or is understood as representing an idea, object, or relationship.Symbols allow people to go beyond what is known or seen by creating linkages between otherwise very different concepts and experiences.All communication (and data processing) is achieved through the use of symbols.Symbols take the form of words, sounds, ....


Neo-Dada - Wikipedia.

Neo-Dada was a movement with audio, visual and literary manifestations that had similarities in method or intent with earlier Dada artwork. It sought to close the gap between art and daily life, and was a combination of playfulness, iconoclasm, and appropriation. In the United States the term was popularized by Barbara Rose in the 1960s and refers primarily, although not ....


Mathematics - Wikipedia.

Mathematics (from Ancient Greek u???u?; mathema: 'knowledge, study, learning') is an area of knowledge that includes such topics as numbers (arithmetic and number theory), formulas and related structures (), shapes and the spaces in which they are contained (), and quantities and their changes (calculus and analysis). Most mathematical activity involves the use of pure ....


Waiting for Godot - Wikipedia.

Waiting for Godot (/ ' g ? d o? / GOD-oh) is a play by Samuel Beckett in which two characters, Vladimir (Didi) and Estragon (Gogo), engage in a variety of discussions and encounters while awaiting the titular Godot, who never arrives. Waiting for Godot is Beckett's translation of his own original French-language play, En attendant Godot, and is subtitled (in English only) "a ....


A New Kind of Science - Wikipedia.

A New Kind of Science is a book by Stephen Wolfram, published by his company Wolfram Research under the imprint Wolfram Media in 2002. It contains an empirical and systematic study of computational systems such as cellular automata.Wolfram calls these systems simple programs and argues that the scientific philosophy and methods appropriate for the study of ....


Personality type - Wikipedia.

An early form of personality type indicator theory was the Four Temperaments system of Galen, based on the four humours model of Hippocrates; an extended five temperaments system based on the classical theory was published in 1958.; One example of personality types is Type A and Type B personality theory.According to this theory, impatient, achievement-oriented people are ....


Piaget's theory of cognitive development - Wikipedia.

Piaget's theory of cognitive development is a comprehensive theory about the nature and development of human intelligence.It was originated by the Swiss developmental psychologist Jean Piaget (1896-1980). The theory deals with the nature of knowledge itself and how humans gradually come to acquire, construct, and use it. Piaget's theory is mainly known as a ....


Category theory - Wikipedia.

The study of categories is an attempt to axiomatically capture what is commonly found in various classes of related mathematical structures by relating them to the structure-preserving functions between them. A systematic study of category theory then allows us to prove general results about any of these types of mathematical structures from the axioms of a category..


Open–closed principle - Wikipedia.

In object-oriented programming, the open-closed principle states "software entities (classes, modules, functions, etc.) should be open for extension, but closed for modification"; that is, such an entity can allow its behaviour to be extended without modifying its source code.. The name open-closed principle has been used in two ways. Both ways use generalizations (for instance ....
