Bonn
The federal city of Bonn ( lat, Bonna) is a city on the banks of the Rhine in the German state of North Rhine-Westphalia, with a population of over 300,000. About south-southeast of Cologne, Bonn is in the southernmost part of the Rhine-Ruhr region, Germany's largest metropolitan area, with over 11 million inhabitants. It is a university city and the birthplace of Ludwig van Beethoven. Founded in the 1st century BC as a Roman settlement in the province Germania Inferior, Bonn is one of Germany's oldest cities. It was the capital city of the Electorate of Cologne from 1597 to 1794, and residence of the Archbishops and Prince-electors of Cologne. From 1949 to 1990, Bonn was the capital of West Germany, and Germany's present constitution, the Basic Law, was declared in the city in 1949. The era when Bonn served as the capital of West Germany is referred to by historians as the Bonn Republic. From 1990 to 1999, Bonn served as the seat of government – but no longer capital – ...

Rodderberg
The Rodderberg is an extinct volcano in the east of the municipality of Wachtberg near Bonn, Germany. The last eruption was 250,000 years ago. It is situated just above the Rhine Valley. Together with the Drachenfels directly opposite, the Rodderberg narrows the Rhine Valley. This gorge portion is the southern limit of the lowland-bay of Cologne. The Rodderberg offers views to the Siebengebirge, the Rhine Valley and up to the Cologne Cathedral, about 50 km away. Geology The Rodderberg detonated in a phreatomagmatic eruption Phreatomagmatic eruptions are volcanic eruptions resulting from interaction between magma and water. They differ from exclusively magmatic eruptions and phreatic eruptions. Unlike phreatic eruptions, the products of phreatomagmatic eruptions cont ... about 250,000 years ago. This happened when the magmatic plume reached the groundwater level of the Rhine (about 50m higher than today). After the explosion, the crater was filled with water t ...

History The district as known today was created in 1969, during the reorganization of the districts in North Rhine-Westphalia, by merging Sieg District with the District of Bonn (from which Bonn itself was separated in 1887 to become an urban district). Sieg District was created in 1825. Geography Geographically Rhein-Sieg District covers the valley of the river Sieg and also, since the merger with the District of Bonn, that of the Rhine around Bonn, as well an area in the most easterly part of the Eifel. Politics Municipal elections are held every five years, in which the district administrator () and distric ...

Water Mill
A watermill or water mill is a mill that uses hydropower. It is a structure that uses a water wheel or water turbine to drive a mechanical process such as milling (grinding), rolling, or hammering. Such processes are needed in the production of many material goods, including flour, lumber, paper, textiles, and many metal products. These watermills may comprise gristmills, sawmills, paper mills, textile mills, hammermills, trip hammering mills, rolling mills, wire drawing mills. One major way to classify watermills is by wheel orientation (vertical or horizontal), one powered by a vertical waterwheel through a gear mechanism, and the other equipped with a horizontal waterwheel without such a mechanism. The former type can be further divided, depending on where the water hits the wheel paddles, into undershot, overshot, breastshot and pitchback (backshot or reverse shot) waterwheel mills. Another way to classify water mills is by an essential trait about their location: tide mill ...

Radome
A radome (a portmanteau of radar and dome) is a structural, weatherproof enclosure that protects a radar antenna (radio), antenna. The radome is constructed of material transparent to radio waves. Radomes protect the antenna from weather and conceal antenna electronic equipment from view. They also protect nearby personnel from being accidentally struck by quickly rotating antennas. Radomes can be constructed in several shapes spherical, geodesic dome, geodesic, planar, etc. depending on the particular application, using various construction materials such as fiberglass, polytetrafluoroethylene, polytetrafluoroethylene (PTFE)-coated fabric, and others. When found on fixed-wing aircraft with forward-looking radar, as are commonly used for object or weather detection, the nose cones often additionally serve as radomes. On aircraft used for airborne early warning and control (AEW&C), a rotating radome, often called a "rotodome", is mounted on the top of the fuselage for 360-degr ...

1042-adendorf2
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by  2, although by other definitions 1 is the second natural number, following  0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ...

Cenotaph
A cenotaph is an empty tomb or a monument erected in honour of a person or group of people whose remains are elsewhere. It can also be the initial tomb for a person who has since been reinterred elsewhere. Although the vast majority of cenotaphs honour individuals, many noted cenotaphs are instead dedicated to the memories of groups of individuals, such as the lost soldiers of a country or of an empire. Etymology The word "cenotaph" in the English Language is derived from the Greek el, κενοτάφιον, kenotaphion, label=none. It is a compound word that is created from the morphological combination of two root words: # el, κενός, kenos, label=none meaning "empty" # el, τάφος, taphos, label=none meaning "tomb", from el, θαπτω, thapto, I bury, label=none History Cenotaphs were common in the ancient world. Many were built in Ancient Egypt, Ancient Greece and across Northern Europe (in the shape of Neolithic barrows). The cenotaph in Whitehall, Lon ...

Stream
A stream is a continuous body of water, body of surface water Current (stream), flowing within the stream bed, bed and bank (geography), banks of a channel (geography), channel. Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long large streams are usually called rivers, while smaller, less voluminous and more intermittent river, intermittent streams are known as streamlets, brooks or creeks. The flow of a stream is controlled by three inputs – surface runoff (from precipitation or meltwater), daylighting (streams), daylighted subterranean river, subterranean water, and surfaced groundwater (Spring (hydrology), spring water). The surface and subterranean water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of precipitation. The stream encompasses surface, subsurface and groundwater fluxes th ...
