James A. Turrell
James Turrell (born May 6, 1943) is an American artist known for his work within the Light and Space movement. Much of Turrell's career has been devoted to a still-unfinished work, '' Roden Crater'', a natural cinder cone crater located outside Flagstaff, Arizona, that he is turning into a massive naked-eye observatory; and for his series of skyspaces, enclosed spaces that frame the sky. Turrell was a MacArthur Fellow in 1984. Background James Turrell was born in Los Angeles, California. His father, Archibald Milton Turrell,Adcock, Craig, ''James Turrell: The Art of Light and Space'', Berkeley/Los Angeles/Oxford : University of California Press, 1990, p. 2. was an aeronautical engineer and educator. His mother, Margaret Hodges Turrell, trained as a medical doctor and later worked in the Peace Corps. His parents were Quakers. Turrell obtained a pilot's license when he was 16 years old. Later, registered as a conscientious objector during the Vietnam War, he flew Budd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Quakers
Quakers are people who belong to a historically Protestant Christian set of denominations known formally as the Religious Society of Friends. Members of these movements ("theFriends") are generally united by a belief in each human's ability to experience the light within or see "that of God in every one". Some profess a priesthood of all believers inspired by the First Epistle of Peter. They include those with evangelical, holiness, liberal, and traditional Quaker understandings of Christianity. There are also Nontheist Quakers, whose spiritual practice does not rely on the existence of God. To differing extents, the Friends avoid creeds and hierarchical structures. In 2017, there were an estimated 377,557 adult Quakers, 49% of them in Africa. Some 89% of Quakers worldwide belong to ''evangelical'' and ''programmed'' branches that hold services with singing and a prepared Bible message coordinated by a pastor. Some 11% practice ''waiting worship'' or ''unprogramme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mary Corse
Mary Corse (born 1945) is an American artist who lives and works in Topanga, California. Fascinated with perceptual phenomena and the idea that light itself can serve as both subject and material in art, Corse's practice can be seen as existing at an crossroads between American Abstract Expressionism and American Minimalism. She is often associated with the male-dominated Light and Space art movement of the 1960s, although her role has only been fully recognized in recent years. She is best known for her experimentation with radiant surfaces in minimalist painting, incorporating materials that reflect light such as glass microspheres. Corse initially attended University of California, Santa Barbara starting in 1963. She later moved on to study at Chouinard Art Institute (now CalArts), earning her B.F.A. in 1968. Work In the mid-1960s, during her time at Chouinard Art Institute, Mary Corse developed an interest in white monochrome paintings, favoring the controlled, geometric sty ...

Robert Irwin (artist)
Robert W. Irwin (born September 12, 1928) is an American installation artist who has explored perception and the conditional in art, often through site-specific, architectural interventions that alter the physical, sensory and temporal experience of space. He began his career as a painter in the 1950s, but in the 1960s shifted to installation work, becoming a pioneer whose work helped to define the aesthetics and conceptual issues of the West Coast Light and Space movement. His early works often employed light and veils of scrim to transform gallery and museum spaces, but since 1975, he has also incorporated landscape projects into his practice. Irwin has conceived over fifty-five site-specific projects, at institutions including the Getty Center (1992–98), Dia:Beacon (1999–2003), and the Chinati Foundation in Marfa, Texas (2001–16). The Museum of Contemporary Art, Los Angeles mounted the first retrospective of his work in 1993; in 2008, the Museum of Contemporary Art Sa ...

Sky Space Salzburg 05
The sky is an unobstructed view upward from the surface of the Earth. It includes the atmosphere and outer space. It may also be considered a place between the ground and outer space, thus distinct from outer space. In the field of astronomy, the sky is also called the celestial sphere. This is an abstract sphere, concentric to the Earth, on which the Sun, Moon, planets, and stars appear to be drifting. The celestial sphere is conventionally divided into designated areas called constellations. Usually, the term ''sky'' informally refers to a perspective from the Earth's surface; however, the meaning and usage can vary. An observer on the surface of the Earth can see a small part of the sky, which resembles a dome (sometimes called the ''sky bowl'') appearing flatter during the day than at night. In some cases, such as in discussing the weather, the sky refers to only the lower, denser layers of the atmosphere. The daytime sky appears blue because air molecules scatter shor ...

Conscription In The United States
In the United States, military conscription, commonly known as the draft, has been employed by the U.S. federal government in six conflicts: the American Revolutionary War, the American Civil War, World War I, World War II, the Korean War, and the Vietnam War. The fourth incarnation of the draft came into being in 1940, through the Selective Training and Service Act. It was the country's first peacetime draft. From 1940 until 1973, during both peacetime and periods of conflict, men were drafted to fill vacancies in the U.S. Armed Forces that could not be filled through voluntary means. Active conscription in the United States ended in 1973, when the U.S. Armed Forces moved to an all-volunteer military. However, conscription remains in place on a contingency basis and all male U.S. citizens, regardless of where they live, and male immigrants, whether documented or undocumented, residing within the United States, who are 18 through 25 are required to register with the Selecti ...

Astronomy
Astronomy () is a natural science that studies astronomical object, celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and chronology of the Universe, evolution. Objects of interest include planets, natural satellite, moons, stars, nebulae, galaxy, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond atmosphere of Earth, Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonian astronomy, Babylonians, Greek astronomy, Greeks, Indian astronomy, Indians, Egyptian astronomy, Egyptians, Chinese astronomy, Chinese, Maya civilization, Maya, and many anc ...

Geology
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of E ...

Mathematics
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting points of ...

Ganzfeld Effect
The Ganzfeld effect (from German for "complete field"), or perceptual deprivation, is a phenomenon of perception caused by exposure to an unstructured, uniform stimulation field. The effect is the result of the brain amplifying neural noise in order to look for the missing visual signals. The noise is interpreted in the higher visual cortex, and gives rise to hallucinations. It has been most studied with vision by staring at an undifferentiated and uniform field of color. The visual effect is described as the loss of vision as the brain cuts off the unchanging signal from the eyes. The result is "seeing black", an apparent sense of blindness. A flickering ganzfeld causes geometrical patterns and colors to appear, and this is the working principle for mind machines and the dream machine. Ganzfeld induction in multiple senses is called multi-modal ganzfeld. This is usually done by wearing ganzfeld goggles in addition to headphones with a uniform stimulus. A related effect is se ...
