Aesthetics, or the philosophy of art, is the study of beauty and taste. It is about interpreting works of art and art movements or theories. The term aesthetic is also used to designate a particular style, for example the "chess aesthetics", or the "Japanese aesthetic".
As well as being applied to art, aesthetics can also be applied to cultural objects. Aesthetic design principles include ornamentation, edge delineation, texture, flow, solemnity, symmetry, color, granularity, the interaction of sunlight and shadows, transcendence, and harmony.
The word aesthetic is also an adjective and adverb relating to cosmetology and medicine, as in aesthetic medicine.
Also spelt æsthetics and esthetics, the word is derived from the Ancient Greek αἰσθητικός (aisthetikos, meaning "esthetic, sensitive, sentient, pertaining to sense perception"), which in turn was derived from αἰσθάνομαι (aisthanomai, meaning "I perceive, feel, sense").
The idea of the aesthetic developed from the idea of taste and beauty. Before the early 1700s, thinkers developed general theories of proportion and harmony, detailed most specifically in architecture and music. An extended, philosophical reflection on aesthetics emerged with the widening of leisure activities in the eighteenth century.
In the pre-modern tradition, the aesthetics of music or musical aesthetics explored the mathematical and cosmological dimensions of rhythmic and harmonic organization. In the eighteenth century, focus shifted to the experience of hearing music, and thus to questions about its beauty and human enjoyment (plaisir and jouissance) of music. The origin of this philosophic shift is sometimes attributed to Baumgarten in the 18th century, followed by Kant. Through their writing, the ancient term aesthetics, meaning sensory perception, received its present-day connotation. In recent decades philosophers have tended to emphasize issues besides beauty and enjoyment. For example, music's capacity to express emotion has been a central issue.
Aesthetics is a sub-discipline of philosophy. In the 20th century, important contributions were made by Peter Kivy, Jerrold Levinson, Roger Scruton, and Stephen Davies. However, many musicians, music critics, and other non-philosophers have contributed to the aesthetics of music. In the 19th century, a significant debate arose between Eduard Hanslick, a music critic and musicologist, and composer Richard Wagner regarding whether instrumental music could communicate emotions to the listener. Harry Partch and some other musicologists, such as Kyle Gann, have studied and tried to popularize microtonal music and the usage of alternate musical scales. Also many modern composers like La Monte Young, Rhys Chatham and Glenn Branca paid much attention to a system of tuning called just intonation.
Portal may refer to:
A web portal is most often one specially designed web site that brings information together from diverse sources in a uniform way. Usually, each information source gets its dedicated area on the page for displaying information (a portlet); often, the user can configure which ones to display. Variants of portals include mashups and intranet "dashboards" for executives and managers. The extent to which content is displayed in a "uniform way" may depend on the intended user and the intended purpose, as well as the diversity of the content. Very often design emphasis is on a certain "metaphor" for configuring and customizing the presentation of the content and the chosen implementation framework and/or code libraries. In addition, the role of the user in an organization may determine which content can be added to the portal or deleted from the portal configuration.
A portal may use a search engine API to permit users to search intranet content as opposed to extranet content by restricting which domains may be searched. Apart from this common search engines feature, web portals may offer other services such as e-mail, news, stock quotes, information from databases and even entertainment content. Portals provide a way for enterprises and organizations to provide a consistent look and feel with access control and procedures for multiple applications and databases, which otherwise would have been different web entities at various URLs. The features available may be restricted by whether access is by an authorized and authenticated user (employee,member) or an anonymous site visitor.
Portal is a mix between a computerized novel and an interactive game. It was published for the Amiga in 1986 by Activision, written by Rob Swigart, produced by Brad Fregger, and programmed by Nexa Corporation. Versions for the Commodore 64, Apple II, and DOS were later released. Versions for the Macintosh and Atari ST were announced and developed, but never formally released. A unique game for its time, Portal was one part text-driven adventure (à la Zork or Planetfall) but with a graphical interface. It is unrelated to the game Portal (2007) by Valve Corporation.
The player, taking on the role of the unnamed astronaut protagonist, returns from a failed 100-year voyage to 61 Cygni to find the Earth devoid of humans. Cars are rusted and covered with moss, the streets are completely barren and everything appears as though the entire human race had just vanished suddenly. The player happens upon a barely functioning computer terminal that is tied into a storytelling mainframe, Homer. Through this interface, the player, assisted by Homer who attempts to weave the information into a coherent narrative, discovers information in order to piece together the occurrences leading to the disappearance of the human race. For instance, spending some time in the Medical Records section may unlock a piece of data in the Science section, and through these links the player can finish the game.
