Radio Astronomy
Radio astronomy is a subfield of astronomy that studies celestial objects at radio frequencies. The first detection of radio waves from an astronomical object was in 1933, when Karl Jansky at Bell Telephone Laboratories reported radiation coming from the Milky Way. Subsequent observations have identified a number of different sources of radio emission. These include stars and galaxies, as well as entirely new classes of objects, such as radio galaxies, quasars, pulsars, and masers. The discovery of the cosmic microwave background radiation, regarded as evidence for the Big Bang theory, was made through radio astronomy. Radio astronomy is conducted using large radio antennas referred to as radio telescopes, that are either used singularly, or with multiple linked telescopes utilizing the techniques of radio interferometry and aperture synthesis. The use of interferometry allows radio astronomy to achieve high angular resolution, as the resolving power of an interferom ...

Woodstock Festival
Woodstock Music and Art Fair, commonly referred to as Woodstock, was a music festival held during August 15–18, 1969, on Max Yasgur's dairy farm in Bethel, New York, United States, southwest of the town of Woodstock. Billed as "an Aquarian Exposition: 3 Days of Peace & Music" and alternatively referred to as the Woodstock Rock Festival, it attracted an audience of more than 400,000 attendees. Thirty-two acts performed outdoors despite sporadic rain. It was one of the largest music festivals held in history. The festival has become widely regarded as a pivotal moment in popular music history as well as a defining event for the counterculture generation. The event's significance was reinforced by a 1970 documentary film, an accompanying soundtrack album, and a song written by Joni Mitchell that became a major hit for both Crosby, Stills, Nash & Young and Matthews Southern Comfort. Music events bearing the Woodstock name were planned for anniversaries, which included the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brush (electric)
A brush or carbon brush is an electrical contact which conducts current between stationary wires and moving parts, most commonly in a rotating shaft. Typical applications include electric motors, alternators and electric generators. The lifespan of a carbon brush depends on how much the motor is used, and how much power is put through the motor. Etymology For certain types of electric motors or generators to function, the coils of the rotor must be connected to complete an electrical circuit. Originally this was accomplished by affixing a copper or brass commutator or ' slip ring' to the shaft, with springs pressing braided copper wire 'brushes' onto the slip rings or commutator which conduct the current. Such brushes arced and even welded as the commutator rotated, because the brush short–circuited adjacent segments. The cure was the introduction of 'high resistance brushes' made from graphite (sometimes with added copper). Although the resistance was of the order of tens ...

Listed Building
In the United Kingdom, a listed building or listed structure is one that has been placed on one of the four statutory lists maintained by Historic England in England, Historic Environment Scotland in Scotland, in Wales, and the Northern Ireland Environment Agency in Northern Ireland. The term has also been used in the Republic of Ireland, where buildings are protected under the Planning and Development Act 2000. The statutory term in Ireland is "protected structure". A listed building may not be demolished, extended, or altered without special permission from the local planning authority, which typically consults the relevant central government agency, particularly for significant alterations to the more notable listed buildings. In England and Wales, a national amenity society must be notified of any work to a listed building which involves any element of demolition. Exemption from secular listed building control is provided for some buildings in current use for worsh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Creamware (company)
Creamware Audio GmbH (typically styled as creamw@re) was a manufacturer of DSP-based sound cards and synthesizers in Siegburg, Germany. These cards are used to create synthesized sounds for audio production in music and other audio environments. The company was founded in 1992 and operated until 2006. In 2007, the company ' Sonic Core' purchased certain Creamware assets and intellectual property. Creamware also developed several digital audio software/hardware combination systems that became popular with radio broadcasters throughout the late 1990s. These systems included 'TripleDAT' and a scaled-down version called 'CutMaster'. Both versions were widely used by German and Canadian commercial radio stations, and state owned Chinese radio stations. About 200 systems were also shipped to Australia, where they were used by government, commercial and public access/community stations. Stations used the software for the production of commercial/sponsorship advertising, audio (radi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Max Planck Institute For Radio Astronomy
The Max Planck Institute for Radio Astronomy (MPIfRA) (German: ''Max-Planck-Institut für Radioastronomie'') is located in Bonn, Germany. It is one of 80 institutes in the Max Planck Society (German: Max-Planck-Gesellschaft). History By combining the already existing radio astronomy faculty of the University of Bonn led by Otto Hachenberg with the new Max Planck institute the Max Planck Institute for Radio Astronomy was formed. In 1972 the 100-m radio telescope in Effelsberg was opened. The institute building was enlarged in 1983 and 2002. The southern wing of the whole complex is occupied by the Argelander Institute of Astronomy of the University of Bonn. Structure The Institute has three main research groups, each with its own Director Departments * Fundamental Physics ( Michael Kramer) * VLBI and Radio Astronomy ( Anton Zensus) * Millimetre Astronomy ( Karl Menten) Independent Research Groups * Lise Meitner Group on Fast Radio Bursts as Astrophysical Tools ...

Stockert (hill)
The Stockert is a 435-metre-high hill which rises between Eschweiler and Holzheim in the district of Euskirchen in the borough of Bad Münstereifel, in the Eifel mountains of Germany, and west of the city of Bonn. Geography The Stockert rises in the west of the Münstereifel Forest.

Effelsberg 100-m Radio Telescope
The Effelsberg 100-m Radio Telescope is a radio telescope in the Ahr Hills (part of the Eifel) in Bad Münstereifel, Germany. For 29 years the Effelsberg Radio Telescope was the largest fully steerable radio telescope on Earth, surpassing the Lovell Telescope in the UK. In 2000, it was surpassed by the Green Bank Observatory's Robert C. Byrd Green Bank Telescope in Green Bank, US, which has a slightly larger elliptical 100 by 110-metre aperture. Geography The telescope is located about 1.3 km northeast of Effelsberg, a southeastern part of the town of Bad Münstereifel in North Rhine-Westphalia. It is less than 300 m west of the 398 m high Hünerberg, which is in neighbouring Rhineland-Palatinate. The boundary is a stream, the Effelsberger Bach, which runs only a few metres east of the telescope. The Effelsberger Bach is 6.5 km long, flowing from the Effelsberger Wald into the Sahrbach, which in turn flows south and into the Ahr river. A hiking pa ...
