Ken Knowlton Kenneth C. Knowlton (born 1931 in Springville, New York), is a computer graphics pioneer, artist, mosaicist and portraitist, who worked at Bell Labs. In 1963, Knowlton developed the BEFLIX (Bell Flicks) programming language for bitmap computer-produced movies, created using an IBM 7094 computer and a Stromberg-Carlson 4020 microfilm recorder. Each frame contained eight shades of grey and a resolution of 252 x 184. Knowlton worked with artists including Stan VanDerBeek and Lillian Schwartz.

re.act.feminism Theresa Hak Kyung Cha: "Mouth to Mouth" (1975). image courtesy: EAI, New York Theresa Hak Kyung Cha (South Korea, USA 1951 - 1982) The subject of "Mouth to Mouth", one of Cha's early films, is language. Eight Korean vowel characters are shown and the vowels inaudibly spoken by the artist. The scenes then slowly fade to black. These presentations of printed characters and articulated vowels are interrupted by video static, which has been interpreted as representing the "loss of language over the course of time".

pearltrees Data Garden interviews artist,Bartholomäus Traubeck. For people that are seeing Years for the first time, can you give a brief description? It’s basically a modified turntable that uses a camera as a pickup and that samples a microscopically small image of the year rings. Those are then translated into sound by programming. It’s not a very direct translation. Artist: The Dream of the Audience Although she lived only 31 years, Theresa Hak Kyung Cha left a substantial and diverse body of work. The primary mediums in which she worked were: ceramic, performance, artist’s books, concrete poetry, film, video, sculpture, mail art, audio, and slide projections. In many cases her work combined aspects of different media, blurring the boundaries between conventionally distinct categories. It was characteristic of Cha to take the thematic and formal approaches developed in one medium and reinterpret them in another; elements of film and video, for example, find their way into artist’s books and vice versa.

Mount Roraima Mount Roraima (Spanish: Monte Roraima [ˈmonte roˈɾaima], also known as Tepuy Roraima and Cerro Roraima; Portuguese: Monte Roraima [ˈmõtʃi ʁoˈɾɐ̃jmɐ]) is the highest of the Pakaraima chain of tepui plateau in South America.[4]:156 First described by the English explorer Sir Walter Raleigh in 1596, its 31 km2 summit area[4]:156 consists on all sides of cliffs rising 400 metres (1,300 ft). The mountain also serves as the triple border point of Venezuela, Brazil and Guyana.[4]:156 Mount Roraima lies on the Guiana Shield in the southeastern corner of Venezuela's 30,000 square kilometres (12,000 sq mi) Canaima National Park forming the highest peak of Guyana's Highland Range.

As Euclidean geometry lies at the intersection of metric geometry and affine geometry, non-Euclidean geometry arises when either the metric requirement is relaxed, or the parallel postulate is set aside. In the latter case one obtains hyperbolic geometry and elliptic geometry, the traditional non-Euclidean geometries. When the metric requirement is relaxed, then there are affine planes associated with the planar algebras which give rise to kinematic geometries that have also been called non-Euclidean geometry. Another way to describe the differences between these geometries is to consider two straight lines indefinitely extended in a two-dimensional plane that are both perpendicular to a third line:

Alfredo Jaar Artist Alfredo Jaar (b.1956) explains how he has always felt that in order to act in the world, he had to first understand the world. Images and media is key to this, he says: "Every single image out there in the world, represents a conception of the world. Represents an ideological conception of the world. They tell us things about the world." In this interview Jaar talks about four works: The Rwanda Project, Searching for Africa in LIFE, From TIME to TIME and The Sound of Silence. For 6 years Jaar followed the news and the western media's lack of reacting to or coverage of the 1994 Rwandan genocide. Schools of fish help squeeze more power from wind farms 8 August 2011Last updated at 19:57 By Hamish Pritchard Science Reporter How Caltech's new wind farm design looks Schools of fish have shown engineers how to squeeze much more power from wind farms. A new wind farm design mimics a school of fish to exploit wind turbulence, and could dramatically improve power output. Familiar propeller-style wind turbines with large sweeping blades have almost reached their limit of efficiency.

Spermine Spermine is a polyamine involved in cellular metabolism found in all eukaryotic cells. Formed from spermidine, it is found in a wide variety of organisms and tissues and is an essential growth factor in some bacteria. It is found as a polycation at physiological pH. Spermine is associated with nucleic acids and is thought to stabilize helical structure, in particular, in viruses.
