Service economyService economy can refer to one or both of two recent economic developments: The increased importance of the service sector in industrialized economies. The current list of Fortune 500 companies contains more service companies and fewer manufacturers than in previous decades. The relative importance of service in a product offering. The service economy in developing countries is mostly concentrated in financial services, hospitality, retail, health, human services, information technology and education.
Fermat's spiralA Fermat's spiral or parabolic spiral is a plane curve with the property that the area between any two consecutive full turns around the spiral is invariant. As a result, the distance between turns grows in inverse proportion to their distance from the spiral center, contrasting with the Archimedean spiral (for which this distance is invariant) and the logarithmic spiral (for which the distance between turns is proportional to the distance from the center). Fermat spirals are named after Pierre de Fermat.
Color fieldColor field painting is a style of abstract painting that emerged in New York City during the 1940s and 1950s. It was inspired by European modernism and closely related to abstract expressionism, while many of its notable early proponents were among the pioneering abstract expressionists. Color field is characterized primarily by large fields of flat, solid color spread across or stained into the canvas creating areas of unbroken surface and a flat picture plane.
Social servicesSocial services are a range of public services intended to provide support and assistance towards particular groups, which commonly include the disadvantaged. They may be provided by individuals, private and independent organisations, or administered by a government agency. Social services are connected with the concept of welfare and the welfare state, as countries with large welfare programs often provide a wide range of social services. Social services are employed to address the wide range of needs of a society.
Formal scienceFormal science is a branch of science studying disciplines concerned with abstract structures described by formal systems, such as logic, mathematics, statistics, theoretical computer science, artificial intelligence, information theory, game theory, systems theory, decision theory, and theoretical linguistics. Whereas the natural sciences and social sciences seek to characterize physical systems and social systems, respectively, using empirical methods, the formal sciences use language tools concerned with characterizing abstract structures described by formal systems.
TachismeNOTOC Tachisme (alternative spelling: Tachism, derived from the French word tache, stain) is a French style of abstract painting popular in the 1940s and 1950s. The term is said to have been first used with regards to the movement in 1951. It is often considered to be the European response and equivalent to abstract expressionism, although there are stylistic differences (American abstract expressionism tended to be more "aggressively raw" than tachisme).
