seen as a subjective mapping from a human perspective (that of the user in the case of abstract or physical artefacts) to the elements or components of some kind of structure or system, which preserves the relationships among the elements or components. Planned architecture manipulates space, volume, texture, light, shadow, or abstract elements in order to achieve pleasing aesthetics. This distinguishes it from applied science or engineering, which usually concentrate more on the functional and feasibility aspects of the design of constructions or structures. In the field of building architecture, the skills demanded of an architect range from the more complex, such as for a hospital or a stadium, to the apparently simpler, such as planning residential houses. Many architectural works may be seen also as cultural and political symbols, or works of art. The role of the architect, though changing, has been central to the successful (and sometimes less than successful) design and implementation of pleasingly built environments in which people live. Ceramics Ceramic art is art made from ceramic materials (including clay), which may take forms such as pottery, tile, figurines, sculpture, and tableware. While some ceramic products are considered fine art, some are considered to be decorative, industrial, or applied art objects. Ceramics may also be considered artefacts in archaeology. Ceramic art can be made by one person or by a group of people. In a pottery or ceramic factory, a group of people design, manufacture, and decorate the pottery. Products from a pottery are sometimes referred to as "art pottery." In a one-person pottery studio, ceramists or potters produce studio pottery. In modern ceramic engineering usage, "ceramics" is the art and science of making objects from inorganic, non-metallic materials by the action of heat. It excludes glass and mosaic made from glass tesserae. Conceptual art Conceptual art is art wherein the concept(s) or idea(s) involved in the work take precedence over traditional aesthetic and material concerns. The inception of the term in the 1960s referred to a strict and focused practice of idea-based art that often defied traditional visual criteria associated with the visual arts in its presentation as text. Through its association with the Young British Artists and the Turner Prize during the 1990s, its popular usage, particularly in the United Kingdom, developed as a synonym for all contemporary art that does not practise the traditional skills of painting and sculpture.
