Avant-gardeIn the arts and in literature, the term avant-garde (advance guard and vanguard) identifies a genre of art, an experimental work of art, and the experimental artist who created the work of art, which usually is aesthetically innovative, whilst initially being ideologically unacceptable to the artistic establishment of the time. The military metaphor of an advance guard identifies the artists and writers whose innovations in style, form, and subject-matter challenge the artistic and aesthetic validity of the established forms of art and the literary traditions of their time; thus how the artists who created the anti-novel and Surrealism were ahead of their times.
Russian avant-gardeThe Russian avant-garde was a large, influential wave of avant-garde modern art that flourished in the Russian Empire and the Soviet Union, approximately from 1890 to 1930—although some have placed its beginning as early as 1850 and its end as late as 1960. The term covers many separate, but inextricably related, art movements that flourished at the time; including Suprematism, Constructivism, Russian Futurism, Cubo-Futurism, Zaum, Imaginism, and Neo-primitivism.
Cubo-FuturismCubo-Futurism (also, Kubo-Futurizm) was an art movement, developed within Russian Futurism, that arose in early 20th century Russian Empire, defined by its amalgamation of the artistic elements found in Italian Futurism and French Analytical Cubism. Cubo-Futurism was the main school of painting and sculpture practiced by the Russian Futurists. In 1913, the term ‘Cubo-Futurism’ first came to describe works from members of the poetry group ‘Hylaeans’, as they moved away from poetic Symbolism towards Futurism and zaum, the experimental “visual and sound poetry of Kruchenykh and Khlebninkov”.
Cultural studiesCultural studies, also called the cultural sciences, is an interdisciplinary field or scientific branch that examines the dynamics of contemporary culture (including its politics and popular culture) and its historical foundations. Cultural studies researchers generally investigate how cultural practices relate to wider systems of power associated with, or operating through, social phenomena. These include ideology, class structures, national formations, ethnicity, sexual orientation, gender, and generation.
ArchitectureArchitecture is the art and technique of designing and building, as distinguished from the skills associated with construction. It is both the process and the product of sketching, conceiving, planning, designing, and constructing buildings or other structures. The term comes ; ; . Architectural works, in the material form of buildings, are often perceived as cultural symbols and as works of art. Historical civilizations are often identified with their surviving architectural achievements.
Architecture of IndiaIndian architecture is rooted in the history, culture, and religion of India. Among several architectural styles and traditions, the best-known include the many varieties of Hindu temple architecture and Indo-Islamic architecture, especially Rajput architecture, Mughal architecture, South Indian architecture, and Indo-Saracenic architecture. Early Indian architecture was made from wood, which did not survive due to rotting and instability in the structures.
DeconstructivismDeconstructivism is a movement of postmodern architecture which appeared in the 1980s. It gives the impression of the fragmentation of the constructed building, commonly characterised by an absence of obvious harmony, continuity, or symmetry. Its name is a portmanteau of Constructivism and "Deconstruction", a form of semiotic analysis developed by the French philosopher Jacques Derrida.
CritiqueCritique is a method of disciplined, systematic study of a written or oral discourse. Although critique is commonly understood as fault finding and negative judgment, it can also involve merit recognition, and in the philosophical tradition it also means a methodical practice of doubt. The contemporary sense of critique has been largely influenced by the Enlightenment critique of prejudice and authority, which championed the emancipation and autonomy from religious and political authorities.
Chinese architectureChinese architecture is the embodiment of an architectural style that has developed over millennia in China and has influenced architecture throughout East Asia. Since its emergence during the early ancient era, the structural principles of its architecture have remained largely unchanged. The main changes involved diverse decorative details.
N-sphereIn mathematics, an n-sphere or a hypersphere is a topological space that is homeomorphic to a standard n-sphere, which is the set of points in (n + 1)-dimensional Euclidean space that are situated at a constant distance r from a fixed point, called the center. It is the generalization of an ordinary sphere in the ordinary three-dimensional space. The "radius" of a sphere is the constant distance of its points to the center. When the sphere has unit radius, it is usual to call it the unit n-sphere or simply the n-sphere for brevity.
3-sphereIn mathematics, a 3-sphere, glome or hypersphere is a higher-dimensional analogue of a sphere. It may be embedded in 4-dimensional Euclidean space as the set of points equidistant from a fixed central point. Analogous to how the boundary of a ball in three dimensions is an ordinary sphere (or 2-sphere, a two-dimensional surface), the boundary of a ball in four dimensions is a 3-sphere (an object with three dimensions). A 3-sphere is an example of a 3-manifold and an n-sphere.
Riemann sphereIn mathematics, the Riemann sphere, named after Bernhard Riemann, is a model of the extended complex plane: the complex plane plus one point at infinity. This extended plane represents the extended complex numbers, that is, the complex numbers plus a value for infinity. With the Riemann model, the point is near to very large numbers, just as the point is near to very small numbers. The extended complex numbers are useful in complex analysis because they allow for division by zero in some circumstances, in a way that makes expressions such as well-behaved.
SphereA sphere () is a geometrical object that is a three-dimensional analogue to a two-dimensional circle. Formally, a sphere is the set of points that are all at the same distance r from a given point in three-dimensional space. That given point is the centre of the sphere, and r is the sphere's radius. The earliest known mentions of spheres appear in the work of the ancient Greek mathematicians. The sphere is a fundamental object in many fields of mathematics. Spheres and nearly-spherical shapes also appear in nature and industry.
Exotic sphereIn an area of mathematics called differential topology, an exotic sphere is a differentiable manifold M that is homeomorphic but not diffeomorphic to the standard Euclidean n-sphere. That is, M is a sphere from the point of view of all its topological properties, but carrying a smooth structure that is not the familiar one (hence the name "exotic"). The first exotic spheres were constructed by in dimension as -bundles over . He showed that there are at least 7 differentiable structures on the 7-sphere.
Homology sphereIn algebraic topology, a homology sphere is an n-manifold X having the homology groups of an n-sphere, for some integer . That is, and for all other i. Therefore X is a connected space, with one non-zero higher Betti number, namely, . It does not follow that X is simply connected, only that its fundamental group is perfect (see Hurewicz theorem). A rational homology sphere is defined similarly but using homology with rational coefficients.
