Prix Ars Electronica 2012 50 Joe Davis - Bacterial Radio
Prix was an American power pop band formed in Memphis, Tennessee, in 1975 by Tommy Hoehn and Jon Tiven. The group ended up primarily as a studio project. Its recordings were produced by Tiven along with former Big Star member Chris Bell (American musician), Chris Bell, who also played guitar and sang backup vocals. Prix is also famous of Banjo playing. Alex Chilton also participated in the recordings, along with session drummer Hilly Michaels. Although the group generated some major record label interest—notably from Mercury Records and Sony Music, Columbia/CBS Records—it ultimately only released a double A-side single on Terry Ork, Ork Records in 1977 and a single on Miracle Records in 1978. Its only live performance came at a CBS Records showcase in 1976. In 1977, just as Ork Records released the first single and booked the group at CBGB, Prix broke up due both to Hoehn's unwillingness to remain in New York and to creative differences. In 1978, two of the songs recorded duri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fog Sculpture
Gas sculpture is a proposal made by Joan Miró in his late writings to make sculptures out of gaseous materials. The idea of a gas sculpture also appeared in the book ''Gog'', by Giovanni Papini (1881–1956). An example of pure water fog sculpture is in the sculpture garden at the National Gallery of Australia in Canberra. A large bank of very small nozzles is arrayed on the edge of a small rush-filled pond, and when the power is switched on a fine mist of fog billows out. The "sculpture" has a continuously changing shape as it is affected by the water, the rushes, and the air currents in the area. Technology Cold water fog nozzle technologies were developed by industry in the late 1960s for factory air particulate control and agricultural orchard freeze prevention. These high pressure systems force filtered water at through custom nozzles to atomize the water into billions of ultra-fine droplets below in size. In industrial applications this also provides cooling due to rap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Facebook
Facebook is an online social media and social networking service owned by American company Meta Platforms. Founded in 2004 by Mark Zuckerberg with fellow Harvard College students and roommates Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes, its name comes from the face book directories often given to American university students. Membership was initially limited to Harvard students, gradually expanding to other North American universities and, since 2006, anyone over 13 years old. As of July 2022, Facebook claimed 2.93 billion monthly active users, and ranked third worldwide among the most visited websites as of July 2022. It was the most downloaded mobile app of the 2010s. Facebook can be accessed from devices with Internet connectivity, such as personal computers, tablets and smartphones. After registering, users can create a profile revealing information about themselves. They can post text, photos and multimedia which are shared with any ...

DIYbio
Do-it-yourself biology (DIY biology, DIY bio) is a growing biotechnological social movement in which individuals, communities, and small organizations study biology and life science using the same methods as traditional research institutions. DIY biology is primarily undertaken by individuals with limited research training from academia or corporations, who then mentor and oversee other DIY biologists with little or no formal training. This may be done as a hobby, as a not-for-profit endeavour for community learning and open-science innovation, or for profit, to start a business. Other terms are also associated with the do-it-yourself biology community. The terms biohacking and wetware hacking emphasize the connection to hacker culture and the hacker ethic. The term hacker is used in the original sense of finding new and clever ways to do things. The term biohacking is also used by the grinder body modification community, which is considered related but distinct from the do-it- ...

University Of Washington Press
The University of Washington Press is an American academic publishing house. The organization is a division of the University of Washington, based in Seattle. Although the division functions autonomously, they have worked to assist the university's efforts in support of the Burke Museum of Natural History and Culture, the Henry M. Jackson School of International Studies, and the Center for Innovation and Research in Graduate Education. Since 1915, they have published the works of first-time writers, including students, poets, and artists, along with authors known throughout the world for their work in the humanities, arts, and sciences. While the day-to-day functions of the organization are carried out independent of the university, the imprint itself is managed by a committee of faculty members, who have been appointed by the university president. Each manuscript must go through a collaborative approval process overseen by the editors and the University Press Committee before b ...

Magnetosphere
In astronomy and planetary science, a magnetosphere is a region of space surrounding an astronomical object in which charged particles are affected by that object's magnetic field. It is created by a celestial body with an active interior dynamo. In the space environment close to a planetary body, the magnetic field resembles a magnetic dipole. Farther out, field lines can be significantly distorted by the flow of electrically conducting plasma, as emitted from the Sun (i.e., the solar wind) or a nearby star. Planets having active magnetospheres, like the Earth, are capable of mitigating or blocking the effects of solar radiation or cosmic radiation, that also protects all living organisms from potentially detrimental and dangerous consequences. This is studied under the specialized scientific subjects of plasma physics, space physics and aeronomy. History Study of Earth's magnetosphere began in 1600, when William Gilbert discovered that the magnetic field on the surface ...

Electron Beam
Cathode rays or electron beam (e-beam) are streams of electrons observed in discharge tubes. If an evacuated glass tube is equipped with two electrodes and a voltage is applied, glass behind the positive electrode is observed to glow, due to electrons emitted from the cathode (the electrode connected to the negative terminal of the voltage supply). They were first observed in 1859 by German physicist Julius Plücker and Johann Wilhelm Hittorf, and were named in 1876 by Eugen Goldstein ''Kathodenstrahlen'', or cathode rays. In 1897, British physicist J. J. Thomson showed that cathode rays were composed of a previously unknown negatively charged particle, which was later named the ''electron''. Cathode-ray tubes (CRTs) use a focused beam of electrons deflected by electric or magnetic fields to render an image on a screen. Description Cathode rays are so named because they are emitted by the negative electrode, or cathode, in a vacuum tube. To release electrons into the tube, th ...

Aurora (astronomy)
An aurora (plural: auroras or aurorae), also commonly known as the polar lights, is a natural light display in Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic). Auroras display dynamic patterns of brilliant lights that appear as curtains, rays, spirals, or dynamic flickers covering the entire sky. Auroras are the result of disturbances in the magnetosphere caused by the solar wind. Major disturbances result from enhancements in the speed of the solar wind from coronal holes and coronal mass ejections. These disturbances alter the trajectories of charged particles in the magnetospheric plasma. These particles, mainly electrons and protons, precipitate into the upper atmosphere (thermosphere/ exosphere). The resulting ionization and excitation of atmospheric constituents emit light of varying colour and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of accelerati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radiotelescope
A radio telescope is a specialized antenna and radio receiver used to detect radio waves from astronomical radio sources in the sky. Radio telescopes are the main observing instrument used in radio astronomy, which studies the radio frequency portion of the electromagnetic spectrum emitted by astronomical objects, just as optical telescopes are the main observing instrument used in traditional optical astronomy which studies the light wave portion of the spectrum coming from astronomical objects. Unlike optical telescopes, radio telescopes can be used in the daytime as well as at night. Since astronomical radio sources such as planets, stars, nebulas and galaxies are very far away, the radio waves coming from them are extremely weak, so radio telescopes require very large antennas to collect enough radio energy to study them, and extremely sensitive receiving equipment. Radio telescopes are typically large parabolic ("dish") antennas similar to those employed in tracking and co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arecibo Observatory
The Arecibo Observatory, also known as the National Astronomy and Ionosphere Center (NAIC) and formerly known as the Arecibo Ionosphere Observatory, is an observatory in Barrio Esperanza, Arecibo, Puerto Rico owned by the US National Science Foundation (NSF). The observatory's main instrument was the Arecibo Telescope, a spherical reflector dish built into a natural sinkhole, with a cable-mount steerable receiver and several radar transmitters for emitting signals mounted above the dish. Completed in 1963, it was the world's largest single-aperture telescope for 53 years, surpassed in July 2016 by the Five-hundred-meter Aperture Spherical Telescope (FAST) in China. Following two breaks in cables supporting the receiver platform in mid-2020, the NSF decommissioned the telescope. A partial collapse of the telescope occurred on December 1, 2020, before controlled demolition could be conducted. In 2022, the NSF announced the telescope will not be rebuilt, with an educational fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RuBisCo Stars
Ribulose-1,5-bisphosphate carboxylase-oxygenase, commonly known by the abbreviations RuBisCo, rubisco, RuBPCase, or RuBPco, is an enzyme () involved in the first major step of carbon fixation, a process by which atmospheric carbon dioxide is converted by plants and other photosynthetic organisms to energy-rich molecules such as glucose. In chemical terms, it catalyzes the carboxylation of ribulose-1,5-bisphosphate (also known as RuBP). It is probably the most abundant enzyme on Earth. Alternative carbon fixation pathways RuBisCO is important biologically because it catalyzes the primary chemical reaction by which inorganic carbon enters the biosphere. While many autotrophic bacteria and archaea fix carbon via the reductive acetyl CoA pathway, the 3-hydroxypropionate cycle, or the reverse Krebs cycle, these pathways are relatively small contributors to global carbon fixation compared to that catalyzed by RuBisCO. Phosphoenolpyruvate carboxylase, unlike RuBisCO, only tempora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
