Art of EuropeThe art of Europe, also known as Western art, encompasses the history of visual art in Europe. European prehistoric art started as mobile Upper Paleolithic rock and cave painting and petroglyph art and was characteristic of the period between the Paleolithic and the Iron Age. Written histories of European art often begin with the Aegean civilizations, dating from the 3rd millennium BC. However a consistent pattern of artistic development within Europe becomes clear only with Ancient Greek art, which was adopted and transformed by Rome and carried; with the Roman Empire, across much of Europe, North Africa and Western Asia.
Hilbert spaceIn mathematics, Hilbert spaces (named after David Hilbert) allow the methods of linear algebra and calculus to be generalized from (finite-dimensional) Euclidean vector spaces to spaces that may be infinite-dimensional. Hilbert spaces arise naturally and frequently in mathematics and physics, typically as function spaces. Formally, a Hilbert space is a vector space equipped with an inner product that induces a distance function for which the space is a complete metric space.
Periods in Western art historyThis is a chronological list of periods in Western art history. An art period is a phase in the development of the work of an artist, groups of artists or art movement. Minoan art Ancient Greek art Roman art Medieval art Early Christian 260–525 Migration Period 300–900 Anglo-Saxon 400–1066 Visigothic 415–711 Pre-Romanesque 500–1000 Insular 600–1200 Viking 700–1100 Byzantine Merovingian Carolingian Ottonian Romanesque 1000–1200 Norman-Sicilian 1100–1200 Gothic 1100–1400 (International Gothic) Renaissance c.
Map symbolA map symbol or cartographic symbol is a graphical device used to visually represent a real-world feature on a map, working in the same fashion as other forms of symbols. Map symbols may include point markers, lines, regions, continuous fields, or text; these can be designed visually in their shape, size, color, pattern, and other graphic variables to represent a variety of information about each phenomenon being represented.
Urban plannerAn urban planner (also known as town planner) is a professional who practices in the field of town planning, urban planning or city planning. An urban planner may focus on a specific area of practice and have a title such as city planner, town planner, regional planner, long-range planner, transportation planner, infrastructure planner, environmental planner, parks planner, physical planner, health planner, planning analyst, urban designer, community development director, economic development specialist, or other similar combinations.
Vector spaceIn mathematics and physics, a vector space (also called a linear space) is a set whose elements, often called vectors, may be added together and multiplied ("scaled") by numbers called scalars. Scalars are often real numbers, but can be complex numbers or, more generally, elements of any field. The operations of vector addition and scalar multiplication must satisfy certain requirements, called vector axioms. The terms real vector space and complex vector space are often used to specify the nature of the scalars: real coordinate space or complex coordinate space.
Map layoutMap layout, also called map composition or (cartographic) page layout, is the part of cartographic design that involves assembling various map elements on a page. This may include the map image itself, along with titles, legends, scale indicators, inset maps, and other elements. It follows principles similar to page layout in graphic design, such as balance, gestalt, and visual hierarchy. The term map composition is also used for the assembling of features and symbols within the map image itself, which can cause some confusion; these two processes share a few common design principles but are distinct procedures in practice.
Normed vector spaceIn mathematics, a normed vector space or normed space is a vector space over the real or complex numbers on which a norm is defined. A norm is a generalization of the intuitive notion of "length" in the physical world. If is a vector space over , where is a field equal to or to , then a norm on is a map , typically denoted by , satisfying the following four axioms: Non-negativity: for every ,. Positive definiteness: for every , if and only if is the zero vector.
Space (mathematics)In mathematics, a space is a set (sometimes called a universe) with some added structure. While modern mathematics uses many types of spaces, such as Euclidean spaces, linear spaces, topological spaces, Hilbert spaces, or probability spaces, it does not define the notion of "space" itself. A space consists of selected mathematical objects that are treated as points, and selected relationships between these points. The nature of the points can vary widely: for example, the points can be elements of a set, functions on another space, or subspaces of another space.
Chinese artChinese art is visual art that originated in or is practiced in China, Greater China or by Chinese artists. Art created by Chinese residing outside of China can also be considered a part of Chinese art when it is based on or draws on Chinese culture, heritage, and history. Early "Stone Age art" dates back to 10,000 BC, mostly consisting of simple pottery and sculptures. After that period, Chinese art, like Chinese history, was typically classified by the succession of ruling dynasties of Chinese emperors, most of which lasted several hundred years.
