Rostock
–
Rostock is the largest city in the north German state Mecklenburg-Vorpommern. Rostock is on the Warnow river, the district of Warnemünde 12 kilometres north of the city centre is directly on the Baltic Sea coast, Rostock is home to one of the oldest universities in the world, the University of Rostock, founded in 1419. The city territory of Rostock stretches for about 20 km along the Warnow to the Baltic Sea, the largest built-up area of Rostock is on the western side of the river. The eastern part of its territory is dominated by industrial estates, Rostock is considered as the only regiopolis in Mecklenburg-Vorpommern. In the 11th century Polabian Slavs founded a settlement at the Warnow river called Roztoc, the Danish king Valdemar I set the town aflame in 1161. Afterwards the place was settled by German traders, initially there were three separate cities, Altstadt around the Alter Markt with St. Petri, Mittelstadt around the Neuer Markt with St. Marien and Neustadt around the Hopfenmarkt with St. Jakobi. In 1218, Rostock was granted Lübeck law city rights by Heinrich Borwin, during the first partition of Mecklenburg following the death of Henry Borwin II of Mecklenburg in 1226, Rostock became the seat of the Lordship of Rostock, which survived for almost a century. In 1251, the city became a member of the Hanseatic League, in the 14th century it was a powerful seaport town with 12,000 inhabitants and the biggest city of Mecklenburg. Ships for cruising the Baltic Sea were constructed in Rostock, the formerly independent fishing village of Warnemünde at the Baltic Sea became a part of Rostock in 1323, to secure the citys access to the Baltic Sea. In 1419, one of the earliest universities in Europe, the University of Rostock, was founded and they took advantage of a riot known as Domfehde, a failed uprising of the impoverished population. Subsequent quarrels with the dukes and persistent plundering led ultimately to a loss of economic, in 1565 there were further clashes with Schwerin that which had far-reaching consequences. Among other things, was the introduction of a beer excise that favoured the dukes. John Albert I advanced on the city with 500 horsemen, after Rostock had refused to take the oath of allegiance. The citizens slighted the fortress the following spring, from 1575 to 1577 the city walls were rebuilt, as was the Lagebusch tower and the Stein Gate in the Dutch Renaissance style. The inscription sit intra te concordia et publica felicitas, which can still be read on the gate, in 1584 it finally came to the Second Rostock Inheritance Agreement, which resulted in a further loss of former tax privileges. At the same time, these inheritance contracts put paid to Rostocks ambition of achieving imperial immediacy as Lübeck had done in 1226, the strategic location of Rostock provoked the envy of its rivals. Danes and Swedes occupied the city twice, first during the Thirty Years War, later, the French, under Napoleon, occupied the town for about a decade until 1813. In nearby Lübeck-Ratekau, Gebhard Leberecht von Blücher, who was born in Rostock and this was only after furious street fighting in the Battle of Lübeck, in which he led some of the cavalry charges himself

Germany
–
Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe. It includes 16 constituent states, covers an area of 357,021 square kilometres, with about 82 million inhabitants, Germany is the most populous member state of the European Union. After the United States, it is the second most popular destination in the world. Germanys capital and largest metropolis is Berlin, while its largest conurbation is the Ruhr, other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart, Düsseldorf and Leipzig. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity, a region named Germania was documented before 100 AD. During the Migration Period the Germanic tribes expanded southward, beginning in the 10th century, German territories formed a central part of the Holy Roman Empire. During the 16th century, northern German regions became the centre of the Protestant Reformation, in 1871, Germany became a nation state when most of the German states unified into the Prussian-dominated German Empire. After World War I and the German Revolution of 1918–1919, the Empire was replaced by the parliamentary Weimar Republic, the establishment of the national socialist dictatorship in 1933 led to World War II and the Holocaust. After a period of Allied occupation, two German states were founded, the Federal Republic of Germany and the German Democratic Republic, in 1990, the country was reunified. In the 21st century, Germany is a power and has the worlds fourth-largest economy by nominal GDP. As a global leader in industrial and technological sectors, it is both the worlds third-largest exporter and importer of goods. Germany is a country with a very high standard of living sustained by a skilled. It upholds a social security and universal health system, environmental protection. Germany was a member of the European Economic Community in 1957. It is part of the Schengen Area, and became a co-founder of the Eurozone in 1999, Germany is a member of the United Nations, NATO, the G8, the G20, and the OECD. The national military expenditure is the 9th highest in the world, the English word Germany derives from the Latin Germania, which came into use after Julius Caesar adopted it for the peoples east of the Rhine. This in turn descends from Proto-Germanic *þiudiskaz popular, derived from *þeudō, descended from Proto-Indo-European *tewtéh₂- people, the discovery of the Mauer 1 mandible shows that ancient humans were present in Germany at least 600,000 years ago. The oldest complete hunting weapons found anywhere in the world were discovered in a mine in Schöningen where three 380, 000-year-old wooden javelins were unearthed

Mecklenburg-Vorpommern
–
Mecklenburg-Vorpommern is a federal state in northern Germany. Mecklenburg-Vorpommern is the sixth largest German state by area, and the least densely populated, three of Germanys fourteen national parks are in Mecklenburg-Vorpommern, in addition to several hundred nature conservation areas. Major cities include Rostock, Schwerin, Neubrandenburg, Stralsund, Greifswald, Wismar, the University of Rostock and the University of Greifswald are among the oldest in Europe. Mecklenburg-Vorpommern was the site of the 33rd G8 summit in 2007, due to its lengthy name, the state is often abbreviated as MV or shortened to MeckPomm. In English, it is translated as Mecklenburg-Western Pomerania or literally Mecklenburg-Cispomerania. Inhabitants are called either Mecklenburger or Pomeranians, the form is never used. The full name in German is pronounced and this is because the digraph <ck> marks a preceding short vowel in High German. Mecklenburg however is within the historical Low German language area, another explanation is that the c comes from a mannerism in High German officialese of writing unnecessary letters, a so-called Letternhäufelung. Human settlement in the area of modern Mecklenburg and Vorpommern began after the Ice Age, about two thousand years ago, Germanic peoples were recorded in the area. Most of them left during the Migration Period, heading towards Spain, Italy, in the 6th century Polabian Slavs populated the area. While Mecklenburg was settled by the Obotrites, Vorpommern was settled by the Veleti, along the coast, Vikings and Slavs established trade posts like Reric, Ralswiek and Menzlin. In the 12th century, Mecklenburg and Vorpommern were conquered by Henry the Lion and incorporated into the Duchy of Saxony, all of Mecklenburg-Vorpommern was settled with Germans in the Ostsiedlung process, starting in the 12th century. In the late 12th century, Henry the Lion, Duke of the Saxons, conquered the Obotrites, subjugated its Nikloting dynasty, in the course of time, German monks, nobility, peasants and traders arrived to settle here. After the 12th century, the territory remained stable and relatively independent of its neighbours, Mecklenburg first became a duchy of the Holy Roman Empire in 1348. Though later partitioned and re-partitioned within the dynasty, Mecklenburg always shared a common history. The states of Mecklenburg-Schwerin and Mecklenburg-Strelitz became Grand Duchies in 1815, Vorpommern, litererally Fore-Pomerania, is the smaller, western part of the former Prussian Province of Pomerania, the eastern part became part of Poland after the end of World War II. In the Middle Ages, the area was ruled by the Pomeranian dukes as part of the Duchy of Pomerania, Pomerania was under Swedish rule after the Peace of Westphalia from 1648 until 1815 as Swedish Pomerania. Pomerania became a province of Prussia in 1815 and remained so until 1945, wartime In May 1945, the armies of the Soviet Union and the Western allies met east of Schwerin

Seaside resort
–
A seaside resort is a resort town or resort hotel, located on the coast. Sometimes it is also an officially accredited title, that is awarded to a town when the requirements are met. Where a beach is the focus for tourists, it may be called a beach resort. The coast has always been a recreational environment, although until the mid-nineteenth century, even in Roman times, the town of Baiae, by the Tyrrhenian Sea in Italy, was a resort for those who were sufficiently prosperous. Mersea Island, in Essex, England was a holiday destination for wealthy Romans living in Colchester. The development of the beach as a leisure resort from the mid-19th century was the first manifestation of what is now the global tourist industry. The first seaside resorts were opened in the 18th century for the aristocracy, the first rolling bathing machines were introduced by 1735. In 1793, Heiligendamm in Mecklenburg, Germany was founded as the first seaside resort of the European continent and this trend was praised and artistically elevated by the new romantic ideal of the picturesque landscape, Jane Austens unfinished novel Sanditon is an example of that. The extension of this form of leisure to the middle and working class began with the development of the railways in the 1840s, in particular, the completion of a branch line to the small seaside town Blackpool from Poulton led to a sustained economic and demographic boom. The growth was intensified by the practice among the Lancashire cotton mill owners of closing the factories for an every year to service. These became known as wakes weeks, each towns mills would close for a different week, allowing Blackpool to manage a steady and reliable stream of visitors over a prolonged period in the summer. A prominent feature of the resort was the promenade and the pleasure piers, in 1863, the North Pier in Blackpool was completed, rapidly becoming a centre of attraction for elite visitors. Central Pier was completed in 1868, with a theatre and a large dance floor. Many popular beach resorts were equipped with bathing machines because even the all-covering beachwear of the period was considered immodest, by the end of the century the English coastline had over 100 large resort towns, some with populations exceeding 50,000. The development of the seaside resort abroad was stimulated by the well developed English love of the beach, the French Riviera alongside the Mediterranean had already become a popular destination for the British upper class by the end of the 18th century. In 1864, the first railway to Nice was completed, making the Riviera accessible to visitors all over Europe. By 1874, residents of foreign enclaves in Nice, most of whom were British, the coastline became renowned for attracting the royalty of Europe, including Queen Victoria and King Edward VII. Continental European attitudes towards gambling and nudity tended to be more lax than in Britain, the place was renamed Monte Carlo

Baltic Sea
–
The Baltic Sea is a sea of the Atlantic Ocean, enclosed by Scandinavia, Finland, the Baltic countries, and the North European Plain. It includes the Gulf of Bothnia, the Bay of Bothnia, the Gulf of Finland, the Gulf of Riga, the sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude. The Baltic Sea is connected by waterways to the White Sea via the White Sea Canal. Traffic history Historically, the Kingdom of Denmark collected Sound Dues from ships at the border between the ocean and the land-locked Baltic Sea and they were collected in the Øresund at Kronborg castle near Helsingør, in the Great Belt at Nyborg. In the Little Belt, the site of intake was moved to Fredericia, the narrowest part of Little Belt is the Middelfart Sund near Middelfart. Oceanography Geographers widely agree that the physical border of the Baltic is a line drawn through the southern Danish islands, Drogden-Sill. The Drogden Sill is situated north of Køge Bugt and connects Dragør in the south of Copenhagen to Malmö, it is used by the Øresund Bridge, including the Drogden Tunnel. By this definition, the Danish Straits are part of the entrance, but the Bay of Mecklenburg, another usual border is the line between Falsterbo, Sweden and Stevns Klint, Denmark, as this is the southern border of Øresund. Its also the border between the shallow southern Øresund and notably deeper water, hydrography and biology Drogden Sill sets a limit to Øresund and Darss Sill, and a limit to the Belt Sea. The shallow sills are obstacles to the flow of salt water from the Kattegat into the basins around Bornholm. The Kattegat and the southwestern Baltic Sea are well oxygenated and have a rich biology, the remainder of the Sea is brackish, poor in oxygen and in species. While Tacitus called it Mare Suebicum after the Germanic people called the Suebi, the origin of the latter name is speculative. Adam of Bremen himself compared the sea with a belt, stating that it is so named because it stretches through the land as a belt and he might also have been influenced by the name of a legendary island mentioned in the Natural History of Pliny the Elder. Pliny mentions an island named Baltia with reference to accounts of Pytheas and it is possible that Pliny refers to an island named Basilia in On the Ocean by Pytheas. Baltia also might be derived from belt and mean near belt of sea, meanwhile, others have suggested that the name of the island originates from the Proto-Indo-European root *bhel meaning white, fair. This root and its meaning were retained in both Lithuanian and Latvian. On this basis, a related hypothesis holds that the name originated from this Indo-European root via a Baltic language such as Lithuanian, yet another explanation is that the name originally meant enclosed sea, bay as opposed to open sea. Some Swedish historians believe the name derives from the god Balder of Nordic mythology, in the Middle Ages the sea was known by variety of names

Warnow
–
The Warnow is a river in the state of Mecklenburg-Vorpommern in Germany. It flows into the Baltic Sea near the town of Rostock, the source of the Warnow is in Grebbin, a small village 10 kilometres north of Parchim, at the western end of the Mecklenburg Lake District. It flows north through Sternberg, Bützow and Schwaan before reaching Rostock, in 2003, Germanys first modern toll road, the Warnow Tunnel was opened, connecting the port of Rostock on the east bank with the west bank of the river. The origins of the name are uncertain, recent work suggests a non-Indo-European element arn, giving rise to the Slavic form Warnow through the prosthesis of /v-/. The Warnabi, a medieval Slavic tribe, probably derived their name from the Warnow, the ancient geographer Claudius Ptolemäus mentioned a river around 150 CE whose location would correspond to the Warnow, which he called the Χαλοῦσος. The river also appears in a few medieval sources under names along the lines of Goderak, Guðakrsá in Knýtlinga saga chapter 119, meanwhile, Arnold of Lübecks Chronica Slavorum mentions that Berno, Apostle of the Obotrites pro Gutdracco Godehardum episcopum venerari constituit. This Gutdracco is otherwise unknown, and there is suspicion that the name of this god arose as a folk-etymologisation of the name of the river

Luft-Fahrzeug-Gesellschaft
–
Luft-Fahrzeug-Gesellschaft, also referred to as LFG, was a German aircraft manufacturer during World War I. Luft-Fahrzeug-Gesellschaft formed on April 30,1908, from the assets of an experimental airship engine company located in Bitterfeld, additional funding for the new enterprise was provided primarily by Krupp, AEG, and a local chemical company. The companys offices were located in Berlin along with the factory at Adlershof, manufacture was transferred to Charlottenburg following a fire on 6 September 1916, allegedly caused by the British Secret Service. Their first project was a design by August von Parseval. This entered service as the PL. II in 1910, during World War I, four were delivered to the German Army and Navy. In total some 25 PL airships were built, flown and delivered to various customers, the PL-26, one of the last, crashed on landing and burnt inside hangar Luftschiffhalle 2 with no fatalities. For the rest of the war the hangars were used mostly for repairs of observation balloons, in 1913 LFG started producing new designs under the trade name Roland to avoid confusion with the Luftverkehrsgesellschaft firm. In 1916 the company developed a version of the Albatros C. Ia as the LFG W. Some parts were built in Bitterfeld, but final assembly and checkout was carried out in new factories in Stralsund and their first successful design was the Roland C. II Walfisch, a two-seat reconnaissance biplane. It had a fuselage, skinned with two layers of long plywood strips glued at opposing diagonal angles around a mold and skinned with fabric both inside and outside. The fuselage filled the gap between the wings, leaving the pilot and observer/gunner over the top wings with an excellent view upward. The fuselage half-shells were each fitted onto a framework of wooden formers. Although it was said to have tricky handling, the Roland C. II had excellent performance, and was also used on long-range missions as a bomber escort. A version with the 200 hp Benz Bz. IV engine and new wing struts was built as the D. III, but only one prototype was ever built, as was the case for the 160 hp Mercedes D. III-powered C. V. The C. II was adapted to the fighter role as the Roland D. I. A fire at the factory severely constrained production, and only 20 were built, a newer version with a more conventional layout, the Roland D. II, followed, whose fuselage was reduced in height to leave a gap with the upper wing but was otherwise similar overall. The competing Albatros D. I was preferred, and only about 230 examples were built, the fuselage to wing gap was further increased in the D. III, but the temperamental 180 hp Argus As. III limited production to only a handful. Six D. IIs were delivered in July 1917 to the Bulgarian Air Force, although the Wickelrumpf style of wood-structure monocoque fuselage was extremely strong, it was also very difficult and time-consuming to build

Heinkel
–
Heinkel Flugzeugwerke was a German aircraft manufacturing company founded by and named after Ernst Heinkel. The companys first great success was the design of the Heinkel He 70 Blitz high-speed mail plane and airliner for Deutsche Luft Hansa in 1932 and it was followed by the two-engine Heinkel He 111 Doppel-Blitz, which became a mainstay of the Luftwaffe during World War II as a bomber. Heinkels most important designers at this point were the twin Günter brothers, Siegfried and Walter, the Heinkel company is most closely associated with aircraft used by the Luftwaffe during World War II. This began with the adaptation of the He 70 and, in particular, Heinkel also provided the Luftwaffes only operational heavy bomber, the Heinkel He 177, although this was never deployed in significant numbers. Heinkel was less successful in selling fighter designs, in 1939, flown by Erich Warsitz, the Heinkel He 176 and Heinkel He 178 became the first aircraft designs to fly under liquid-fuel rocket and turbojet power respectively. Heinkel was the first to develop a jet fighter to prototype stage, the Heinkel He 280, thereafter, the Allies began intensive aerial reconnaissance intended to learn more about the German jet aircraft programme. The He 219 night fighter was the first German aircraft to have retracting tricycle gear, Heinkel was a major user of Sachsenhausen concentration camp labour, using between 6,000 and 8,000 prisoners on the He 177 bomber. Following the war, Heinkel was prohibited from manufacturing aircraft and instead built bicycles, motor scooters, the company eventually returned to aircraft in the mid-1950s, licence building F-104 Starfighters for the West German Luftwaffe. It competed with the BMW Isetta and the Messerschmitt KR200 and it had a unit body and a four-stroke single-cylinder engine. Heinkel stopped manufacturing the Kabine in 1958 but production continued under licence, first by Dundalk Engineering Company in Ireland, Heinkel introduced the Tourist motor scooter in the 1950s which was known for its reliability. A large and relatively heavy touring machine, it provided weather protection with a full fairing. Heinkel also made a lighter 150 cc scooter called the Heinkel 150, Heinkel built the Perle moped from 1954 to 1957. The Perle was a cycle with a cast alloy unit frame, rear suspension, a fully enclosed chain with part of the chain enclosure integral with the swingarm. This high level of sophistication came at a high cost, approximately twenty-seven thousand Perles were sold.

Culture of East Germany
–
The culture of East Germany varied throughout the years due to the political and historical events that took place in the 20th century, especially as a result of Nazism and Communism. A reflection on the history of arts and culture in East Germany reveals complex relationships between artists and the state, between oppositional and conformist art. In four decades, East Germany developed a culture and produced works of literature, film, visual arts, music. Popular culture specialities included among others a high popularity of nudism in Eastern Germany, in the 1950s the officially encouraged form of art was known as Socialist Realism. This was intended to depict everyday life under Socialism in a way that showed the benefits of living and working in East Germany, any text published in the GDR was governmentally controlled. The main newspaper was Neues Deutschland, the newspaper of the Socialist Unity Party of Germany. The official newspaper of the Free German Youth was Junge Welt, Das Magazin survived the unification of Germany. Soviet Sputnik in German was too liberal for GDR in 1988, rock bands were expected to sing in German only. This seemed a logical constraint to party leaders but was unpopular amongst young people. Another problem for the authorities was having to check song texts very carefully for anti-state tendencies, the band Renft, for example, fell foul of the authorities, which eventually led to its being banned and disbanded. The Puhdys, Stern-Combo Meißen and Karat were popular mainstream bands, like other mainstream acts, they appeared in youth magazines such as Neues Leben and Das Magazin. Nina Hagen published her first hit Du hast den Farbfilm vergessen in 1974, influences from the West were heard everywhere, because TV and radio that came from the Klassenfeind could be received in many parts of the east, too. The Western influence led to the formation of underground groups with a decisively western-oriented sound. Two such bands were Die Skeptiker, as well as Feeling B, several prestigious ensembles had roots in the pre-War period. Leipzig Gewandhaus Orchestra was led by Kurt Masur since 1970, the Staatskapelle Dresden was led by Herbert Blomstedt since 1975. In 1980 this museum received more than 70,000 visitors, in Leipzig, an enormous archive with recordings of all of Bachs music was compiled, along with many historical documents and letters both to and from him. Werner Neumann founded the Bach-Archiv Leipzig in 1950, every second year, school children from across East Germany gathered for a Bach competition held in East Berlin. Every four years an international Bach competition for keyboard and strings was held, thomanerchor registered a number of Bachs works

Bauhaus
–
The Bauhaus was founded by Walter Gropius in Weimar. Nonetheless, it was founded with the idea of creating a work of art in which all arts, including architecture. The Bauhaus style later became one of the most influential currents in modern design, Modernist architecture and art, design, the Bauhaus had a profound influence upon subsequent developments in art, architecture, graphic design, interior design, industrial design, and typography. Although the school was closed, the continued to spread its idealistic precepts as they left Germany. The changes of venue and leadership resulted in a constant shifting of focus, technique, instructors, many Germans of left-wing views were influenced by the cultural experimentation that followed the Russian Revolution, such as constructivism. Such influences can be overstated, Gropius did not share these radical views, thus, the Bauhaus style, also known as the International Style, was marked by the absence of ornamentation and by harmony between the function of an object or a building and its design. In its first seven years, the Werkbund came to be regarded as the body on questions of design in Germany. The entire movement of German architectural modernism was known as Neues Bauen, beginning in June 1907, Peter Behrens pioneering industrial design work for the German electrical company AEG successfully integrated art and mass production on a large scale. Behrens was a member of the Werkbund, and both Walter Gropius and Adolf Meyer worked for him in this period. The Bauhaus was founded at a time when the German zeitgeist had turned from emotional Expressionism to the matter-of-fact New Objectivity, beyond the Bauhaus, many other significant German-speaking architects in the 1920s responded to the same aesthetic issues and material possibilities as the school. They also responded to the promise of a minimal dwelling written into the new Weimar Constitution, ernst May, Bruno Taut, and Martin Wagner, among others, built large housing blocks in Frankfurt and Berlin. The acceptance of modernist design into everyday life was the subject of publicity campaigns, well-attended public exhibitions like the Weissenhof Estate, films, the Vkhutemas, the Russian state art and technical school founded in 1920 in Moscow, has been compared to Bauhaus. Founded a year after the Bauhaus school, Vkhutemas has close parallels to the German Bauhaus in its intent, organization, the two schools were the first to train artist-designers in a modern manner. Vkhutemas was a school than the Bauhaus, but it was less publicised outside the Soviet Union. With the internationalism of modern architecture and design, there were exchanges between the Vkhutemas and the Bauhaus. In addition, El Lissitzkys book Russia, an Architecture for World Revolution published in German in 1930 featured several illustrations of Vkhutemas/Vkhutein projects there. The school was founded by Walter Gropius in Weimar in 1919 as a merger of the Grand Ducal School of Arts and Crafts and the Weimar Academy of Fine Art. Its roots lay in the arts and crafts founded by the Grand Duke of Saxe-Weimar-Eisenach in 1906

Fish market
–
For the Sydney station, see Fish Market tram stop. A fish market is a marketplace for selling fish products and it can be dedicated to wholesale trade between fishermen and fish merchants, or to the sale of seafood to individual consumers, or to both. Retail fish markets, a type of wet market, often sell street food as well. Fish markets range in size from small stalls, such as the one in the photo at the right, to the great Tsukiji fish market in Tokyo. The term fish market can refer to the process of fish marketing in general. Fish markets were known in antiquity and they served as a public space where large numbers of people could gather and discuss current events and local politics. Because seafood is quick to spoil, fish markets are historically most often found in seaside towns, once ice or other simple cooling methods became available, some were also established in large inland cities that had good trade routes to the coast. Since refrigeration and rapid transport became available in the 19th and 20th century, consequently, most major fish markets now mainly deal with wholesale trade, and the existing major fish retail markets continue to operate as much for traditional reasons as for commercial ones. Both types of markets are often tourist attractions as well. The following is an incomplete list of fish markets. Tsukiji fish market, Tokyo, Japan, the worlds largest fish market, la Nueva Viga Market, Mexico City, Mexico, the worlds second largest fish market.

Edvard Munch
–
One of his best known works is The Scream of 1893. Edvard Munch was born in a farmhouse in the village of Ådalsbruk in Løten, United Kingdoms of Sweden and Norway, to Laura Catherine Bjølstad and Christian Munch, Christian was a doctor and medical officer who married Laura, a woman half his age, in 1861. Edvard had a sister, Johanne Sophie, and three younger siblings, Peter Andreas, Laura Catherine, and Inger Marie. Both Sophie and Edvard appear to have inherited their artistic talent from their mother, Edvard Munch was related to painter Jacob Munch and historian Peter Andreas Munch. The family moved to Christiania in 1864 when Christian Munch was appointed medical officer at Akershus Fortress, Edvards mother died of tuberculosis in 1868, as did Munchs favorite sister Johanne Sophie in 1877. After their mothers death, the Munch siblings were raised by their father, often ill for much of the winters and kept out of school, Edvard would draw to keep himself occupied. He was tutored by his mates and his aunt. Christian Munch also instructed his son in history and literature, and entertained the children with vivid ghost-stories, as Edvard remembered it, Christians positive behavior toward his children was overshadowed by his morbid pietism. Munch wrote, My father was temperamentally nervous and obsessively religious—to the point of psychoneurosis, from him I inherited the seeds of madness. The angels of fear, sorrow, and death stood by my side since the day I was born, Christian reprimanded his children by telling them that their mother was looking down from heaven and grieving over their misbehavior. The oppressive religious milieu, plus Edvards poor health and the vivid ghost stories, helped inspire his macabre visions and nightmares, one of Munchs younger sisters, Laura, was diagnosed with mental illness at an early age. Of the five siblings, only Andreas married, but he died a few months after the wedding, Munch would later write, I inherited two of mankinds most frightful enemies—the heritage of consumption and insanity. Christian Munchs military pay was low, and his attempts to develop a private side practice failed, keeping his family in genteel. They moved frequently from one flat to another. Munchs early drawings and watercolors depicted these interiors, and the objects, such as medicine bottles and drawing implements. By his teens, art dominated Munchs interests, at thirteen, Munch had his first exposure to other artists at the newly formed Art Association, where he admired the work of the Norwegian landscape school. He returned to copy the paintings, and soon he began to paint in oils, in 1879, Munch enrolled in a technical college to study engineering, where he excelled in physics, chemistry and math. He learned scaled and perspective drawing, but frequent illnesses interrupted his studies, the following year, much to his fathers disappointment, Munch left the college determined to become a painter

The Scream
–
The Scream is the popular name given to each of four versions of a composition, created as both paintings and pastels, by Norwegian Expressionist artist Edvard Munch between 1893 and 1910. The German title Munch gave these works is Der Schrei der Natur, the works show a figure with an agonized expression against a landscape with a tumultuous orange sky. Arthur Lubow has described The Scream as an icon of modern art, Edvard Munch created the four versions in various media. The National Gallery in Oslo, Norway, holds one of two painted versions, the Munch Museum holds the other painted version and a pastel version from 1893. These three versions have not traveled for years, the fourth version was sold for $119,922,600 at Sothebys Impressionist and Modern Art auction on 2 May 2012 to financier Leon Black, the fourth highest nominal price paid for a painting at auction. The painting was on display in the Museum of Modern Art in New York from October 2012 to April 2013, also in 1895, Munch created a lithograph stone of the image. Of the lithograph prints produced by Munch, several examples survive, only approximately four dozen prints were made before the original stone was resurfaced by the printer in Munchs absence. The Scream has been the target of several high-profile art thefts, in 1994, the version in the National Gallery was stolen. It was recovered months later. In 2004, both The Scream and Madonna were stolen from the Munch Museum, and were recovered two years later. The original German title given by Munch to his work was Der Schrei der Natur, the Norwegian word skrik usually is translated as scream, but is cognate with the English shriek. Occasionally, the painting also has been called The Cry and he later described his inspiration for the image, One evening I was walking along a path, the city was on one side and the fjord below. I stopped and looked out over the sun was setting. I sensed a scream passing through nature, it seemed to me that I heard the scream, I painted this picture, painted the clouds as actual blood. This explanation has been disputed by scholars, who note that Munch was a painter and was not primarily interested in literal renderings of what he had seen. Alternatively, it has suggested that the proximity of both a slaughterhouse and a lunatic asylum to the site depicted in the painting may have offered some inspiration. The scene was identified as being the view from a road overlooking Oslo, at the time of painting the work, Munchs manic depressive sister Laura Catherine was a patient at the asylum at the foot of Ekeberg. In 2004, an Italian anthropologist speculated that Munch might have seen a mummy in Florences Museum of Natural History, nonetheless, later studies have confirmed Rosenblums suggestion, disproving the Italian theory, for Munch had not been to Florence until after painting The Scream

Scale model
–
This enables it to demonstrate some behavior or property of the original object without examining the original object itself. The most familiar scale models represent the appearance of an object in miniature. Scale models are used in fields including engineering, architecture, film making, military command, salesmanship. While each field may use a model for a different purpose, all scale models are based on the same principles. The detail requirements vary depending on the needs of the modeler, in general a scale model must be designed and built primarily considering similitude theory. However, other requirements concerning practical issues must also be considered, similitude is the theory and art of predicting prototype performance from scale model observations. The main requirement of similitude is all dimensionless quantities must be equal for both the model and the prototype under the conditions the modeler desires to make observations. Dimensionless quantities are generally referred to as Pi terms, or π terms, in many fields the π terms are well established. For example, in dynamics, a well known dimensionless number called the Reynolds number comes up frequently in scale model tests with fluid in motion relative to a stationary surface. An example of the Reynolds number and its use in similitude theory satisfaction can be observed in the scale model testing of fluid flow in a horizontal pipe, one method to determine the dimensionless quantities of concern for a given problem is to use dimensional analysis. Practical concerns include the cost to construct the model, available test facilities to condition and observe the model, the availability of certain materials, and even who will build it. Practical requirements are very diverse depending on the purpose of the scale model. As an example, perhaps an aerospace company needs to test a new wing shape, however, if a facility such as this one cant be used, perhaps due to cost constraints, the similitude requirements must be relaxed or the test redesigned to accommodate the limitation. In this case, concessions must be made for reasons to the similitude requirements. An example of this from fluid dynamics is flow of a liquid in a horizontal pipe, possible π terms to consider in this situation are Reynolds number, Weber number, Froude number, and Mach number. For this flow configuration, however, no tension is involved. Also, compression of the fluid is not applicable, so the Mach number can be disregarded, finally, gravity is not responsible for the flow, so the Froude number can also be disregarded. This leaves the modeler with only the Reynolds number to worry about in terms of equating its values for the scale model, in general, scale models can be classified into three classes depending on the degree of similitude satisfaction they exhibit

Solar System
–
The Solar System is the gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. Of those objects that orbit the Sun directly, the largest eight are the planets, with the remainder being significantly smaller objects, such as dwarf planets, of the objects that orbit the Sun indirectly, the moons, two are larger than the smallest planet, Mercury. The Solar System formed 4.6 billion years ago from the collapse of a giant interstellar molecular cloud. The vast majority of the mass is in the Sun. The four smaller inner planets, Mercury, Venus, Earth and Mars, are terrestrial planets, being composed of rock. The four outer planets are giant planets, being more massive than the terrestrials. All planets have almost circular orbits that lie within a flat disc called the ecliptic. The Solar System also contains smaller objects, the asteroid belt, which lies between the orbits of Mars and Jupiter, mostly contains objects composed, like the terrestrial planets, of rock and metal. Beyond Neptunes orbit lie the Kuiper belt and scattered disc, which are populations of trans-Neptunian objects composed mostly of ices, within these populations are several dozen to possibly tens of thousands of objects large enough that they have been rounded by their own gravity. Such objects are categorized as dwarf planets, identified dwarf planets include the asteroid Ceres and the trans-Neptunian objects Pluto and Eris. In addition to two regions, various other small-body populations, including comets, centaurs and interplanetary dust clouds. Six of the planets, at least four of the dwarf planets, each of the outer planets is encircled by planetary rings of dust and other small objects. The solar wind, a stream of charged particles flowing outwards from the Sun, the heliopause is the point at which pressure from the solar wind is equal to the opposing pressure of the interstellar medium, it extends out to the edge of the scattered disc. The Oort cloud, which is thought to be the source for long-period comets, the Solar System is located in the Orion Arm,26,000 light-years from the center of the Milky Way. For most of history, humanity did not recognize or understand the concept of the Solar System, the invention of the telescope led to the discovery of further planets and moons. The principal component of the Solar System is the Sun, a G2 main-sequence star that contains 99. 86% of the known mass. The Suns four largest orbiting bodies, the giant planets, account for 99% of the mass, with Jupiter. The remaining objects of the Solar System together comprise less than 0. 002% of the Solar Systems total mass, most large objects in orbit around the Sun lie near the plane of Earths orbit, known as the ecliptic

Diameter
–
In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle, both definitions are also valid for the diameter of a sphere. In more modern usage, the length of a diameter is called the diameter. In this sense one speaks of the rather than a diameter, because all diameters of a circle or sphere have the same length. Both quantities can be calculated efficiently using rotating calipers, for a curve of constant width such as the Reuleaux triangle, the width and diameter are the same because all such pairs of parallel tangent lines have the same distance. For an ellipse, the terminology is different. A diameter of an ellipse is any chord passing through the midpoint of the ellipse, for example, conjugate diameters have the property that a tangent line to the ellipse at the endpoint of one of them is parallel to the other one. The longest diameter is called the major axis, the word diameter is derived from Greek διάμετρος, diameter of a circle, from διά, across, through and μέτρον, measure. It is often abbreviated DIA, dia, d, or ⌀, the definitions given above are only valid for circles, spheres and convex shapes. However, they are cases of a more general definition that is valid for any kind of n-dimensional convex or non-convex object. The diameter of a subset of a space is the least upper bound of the set of all distances between pairs of points in the subset. So, if A is the subset, the diameter is sup, if the distance function d is viewed here as having codomain R, this implies that the diameter of the empty set equals −∞. Some authors prefer to treat the empty set as a case, assigning it a diameter equal to 0. For any solid object or set of scattered points in n-dimensional Euclidean space, in medical parlance concerning a lesion or in geology concerning a rock, the diameter of an object is the supremum of the set of all distances between pairs of points in the object. In differential geometry, the diameter is an important global Riemannian invariant, the symbol or variable for diameter, ⌀, is similar in size and design to ø, the Latin small letter o with stroke. In Unicode it is defined as U+2300 ⌀ Diameter sign, on an Apple Macintosh, the diameter symbol can be entered via the character palette, where it can be found in the Technical Symbols category. The character will not display correctly, however, since many fonts do not include it. In many situations the letter ø is a substitute, which in Unicode is U+00F8 ø

Sun
–
The Sun is the star at the center of the Solar System. It is a perfect sphere of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process. It is by far the most important source of energy for life on Earth. Its diameter is about 109 times that of Earth, and its mass is about 330,000 times that of Earth, accounting for about 99. 86% of the total mass of the Solar System. About three quarters of the Suns mass consists of hydrogen, the rest is mostly helium, with smaller quantities of heavier elements, including oxygen, carbon, neon. The Sun is a G-type main-sequence star based on its spectral class and it formed approximately 4.6 billion years ago from the gravitational collapse of matter within a region of a large molecular cloud. Most of this matter gathered in the center, whereas the rest flattened into a disk that became the Solar System. The central mass became so hot and dense that it eventually initiated nuclear fusion in its core and it is thought that almost all stars form by this process. The Sun is roughly middle-aged, it has not changed dramatically for more than four billion years and it is calculated that the Sun will become sufficiently large enough to engulf the current orbits of Mercury, Venus, and probably Earth. The enormous effect of the Sun on Earth has been recognized since prehistoric times, the synodic rotation of Earth and its orbit around the Sun are the basis of the solar calendar, which is the predominant calendar in use today. The English proper name Sun developed from Old English sunne and may be related to south, all Germanic terms for the Sun stem from Proto-Germanic *sunnōn. The English weekday name Sunday stems from Old English and is ultimately a result of a Germanic interpretation of Latin dies solis, the Latin name for the Sun, Sol, is not common in general English language use, the adjectival form is the related word solar. The term sol is used by planetary astronomers to refer to the duration of a solar day on another planet. A mean Earth solar day is approximately 24 hours, whereas a mean Martian sol is 24 hours,39 minutes, and 35.244 seconds. From at least the 4th Dynasty of Ancient Egypt, the Sun was worshipped as the god Ra, portrayed as a falcon-headed divinity surmounted by the solar disk, and surrounded by a serpent. In the New Empire period, the Sun became identified with the dung beetle, in the form of the Sun disc Aten, the Sun had a brief resurgence during the Amarna Period when it again became the preeminent, if not only, divinity for the Pharaoh Akhenaton. The Sun is viewed as a goddess in Germanic paganism, Sól/Sunna, in ancient Roman culture, Sunday was the day of the Sun god. It was adopted as the Sabbath day by Christians who did not have a Jewish background, the symbol of light was a pagan device adopted by Christians, and perhaps the most important one that did not come from Jewish traditions

Orbit
–
In physics, an orbit is the gravitationally curved path of an object around a point in space, for example the orbit of a planet about a star or a natural satellite around a planet. Normally, orbit refers to a regularly repeating path around a body, to a close approximation, planets and satellites follow elliptical orbits, with the central mass being orbited at a focal point of the ellipse, as described by Keplers laws of planetary motion. For ease of calculation, in most situations orbital motion is adequately approximated by Newtonian Mechanics, historically, the apparent motions of the planets were described by European and Arabic philosophers using the idea of celestial spheres. This model posited the existence of perfect moving spheres or rings to which the stars and it assumed the heavens were fixed apart from the motion of the spheres, and was developed without any understanding of gravity. After the planets motions were accurately measured, theoretical mechanisms such as deferent. Originally geocentric it was modified by Copernicus to place the sun at the centre to help simplify the model, the model was further challenged during the 16th century, as comets were observed traversing the spheres. The basis for the understanding of orbits was first formulated by Johannes Kepler whose results are summarised in his three laws of planetary motion. Second, he found that the speed of each planet is not constant, as had previously been thought. Third, Kepler found a relationship between the orbital properties of all the planets orbiting the Sun. For the planets, the cubes of their distances from the Sun are proportional to the squares of their orbital periods. Jupiter and Venus, for example, are respectively about 5.2 and 0.723 AU distant from the Sun, their orbital periods respectively about 11.86 and 0.615 years. The proportionality is seen by the fact that the ratio for Jupiter,5. 23/11.862, is equal to that for Venus,0. 7233/0.6152. Idealised orbits meeting these rules are known as Kepler orbits, isaac Newton demonstrated that Keplers laws were derivable from his theory of gravitation and that, in general, the orbits of bodies subject to gravity were conic sections. Newton showed that, for a pair of bodies, the sizes are in inverse proportion to their masses. Where one body is more massive than the other, it is a convenient approximation to take the center of mass as coinciding with the center of the more massive body. Lagrange developed a new approach to Newtonian mechanics emphasizing energy more than force, in a dramatic vindication of classical mechanics, in 1846 le Verrier was able to predict the position of Neptune based on unexplained perturbations in the orbit of Uranus. This led astronomers to recognize that Newtonian mechanics did not provide the highest accuracy in understanding orbits, in relativity theory, orbits follow geodesic trajectories which are usually approximated very well by the Newtonian predictions but the differences are measurable. Essentially all the evidence that can distinguish between the theories agrees with relativity theory to within experimental measurement accuracy

Pluto
–
Pluto is a dwarf planet in the Kuiper belt, a ring of bodies beyond Neptune. It was the first Kuiper belt object to be discovered, Pluto was discovered by Clyde Tombaugh in 1930 and was originally considered to be the ninth planet from the Sun. After 1992, its planethood was questioned following the discovery of objects of similar size in the Kuiper belt. In 2005, Eris, which is 27% more massive than Pluto, was discovered and this led the International Astronomical Union to define the term planet formally in 2006, during their 26th General Assembly. That definition excluded Pluto and reclassified it as a dwarf planet, Pluto is the largest and second-most-massive known dwarf planet in the Solar System and the ninth-largest and tenth-most-massive known object directly orbiting the Sun. It is the largest known trans-Neptunian object by volume but is less massive than Eris, like other Kuiper belt objects, Pluto is primarily made of ice and rock and is relatively small—about one-sixth the mass of the Moon and one-third its volume. It has an eccentric and inclined orbit during which it ranges from 30 to 49 astronomical units or AU from the Sun. This means that Pluto periodically comes closer to the Sun than Neptune, light from the Sun takes about 5.5 hours to reach Pluto at its average distance. Pluto has five moons, Charon, Styx, Nix, Kerberos. Pluto and Charon are sometimes considered a system because the barycenter of their orbits does not lie within either body. The IAU has not formalized a definition for binary dwarf planets, on July 14,2015, the New Horizons spacecraft became the first spacecraft to fly by Pluto. During its brief flyby, New Horizons made detailed measurements and observations of Pluto, on October 25,2016, at 05,48 pm ET, the last bit of data was received from New Horizons from its close encounter with Pluto on July 14,2015. In the 1840s, Urbain Le Verrier used Newtonian mechanics to predict the position of the then-undiscovered planet Neptune after analysing perturbations in the orbit of Uranus. Subsequent observations of Neptune in the late 19th century led astronomers to speculate that Uranuss orbit was being disturbed by another planet besides Neptune, by 1909, Lowell and William H. Pickering had suggested several possible celestial coordinates for such a planet. Lowell and his observatory conducted his search until his death in 1916, unknown to Lowell, his surveys had captured two faint images of Pluto on March 19 and April 7,1915, but they were not recognized for what they were. There are fourteen other known prediscovery observations, with the oldest made by the Yerkes Observatory on August 20,1909. Percivals widow, Constance Lowell, entered into a legal battle with the Lowell Observatory over her late husbands legacy. Tombaughs task was to image the night sky in pairs of photographs, then examine each pair

IAU definition of planet
–
A non-satellite body fulfilling only the first two of these criteria is classified as a dwarf planet. According to the IAU, planets and dwarf planets are two classes of objects. A non-satellite body fulfilling only the first criterion is termed a small Solar System body, an alternate proposal included dwarf planets as a subcategory of planets, but IAU members voted against this proposal. The definition was a one, and has drawn both support and criticism from different astronomers, but has remained in use. According to this definition, there are eight planets in the Solar System. The definition distinguishes planets from smaller bodies and is not useful outside the Solar System, extrasolar planets, or exoplanets, are covered separately under a complementary 2003 draft guideline for the definition of planets, which distinguishes them from dwarf stars, which are larger. Before the discoveries of the early 21st century, astronomers had no real need for a definition for planets. With the discovery of Pluto in 1930, astronomers considered the Solar System to have nine planets, along with thousands of bodies such as asteroids. Pluto was thought to be larger than Mercury, in 1978, the discovery of Plutos moon Charon radically changed this picture. By measuring Charons orbital period, astronomers could accurately calculate Plutos mass for the first time, in the 1990s, astronomers began finding other objects at least as far away as Pluto, now known as Kuiper Belt objects, or KBOs. Many of these some of Plutos key orbital characteristics and are now called plutinos. Pluto came to be seen as the largest member of a new class of objects, Plutos eccentric and inclined orbit, while very unusual for a planet in the Solar System, fits in well with the other KBOs. New York Citys newly renovated Hayden Planetarium did not include Pluto in its exhibit of the planets when it reopened as the Rose Center for Earth, astronomers also knew that more objects as large as Pluto would be discovered, and the number of planets would start growing quickly. They were also concerned about the classification of planets in other planetary systems, in 2006, the matter came to a head with the first measurement of the size of 2003 UB313. That measurement had showed Eris to appear to be larger than Pluto. The process of new discoveries spurring a contentious refinement of Plutos categorization echoed a debate in the 19th century that began with the discovery of Ceres on January 1,1801, astronomers immediately declared the tiny object to be the missing planet between Mars and Jupiter. Within four years, however, the discovery of two objects with comparable sizes and orbits had cast doubt on this new thinking. By 1851, the number of planets had grown to 23, astronomers began cataloguing them separately and began calling them asteroids instead of planets
21.
Dwarf planet
–
A dwarf planet is a planetary-mass object that is neither a planet nor a natural satellite. The International Astronomical Union currently recognizes five dwarf planets, Ceres, Pluto, Haumea, Makemake, another hundred or so known objects in the Solar System are suspected to be dwarf planets. Individual astronomers recognize several of these, and in August 2011 Mike Brown published a list of 390 candidate objects, Stern states that there are more than a dozen known dwarf planets. Only two of these bodies, Ceres and Pluto, have observed in enough detail to demonstrate that they actually fit the IAUs definition. The IAU accepted Eris as a dwarf planet because it is more massive than Pluto and they subsequently decided that unnamed trans-Neptunian objects with an absolute magnitude brighter than +1 are to be named under the assumption that they are dwarf planets. The classification of bodies in other systems with the characteristics of dwarf planets has not been addressed. Starting in 1801, astronomers discovered Ceres and other bodies between Mars and Jupiter which were for some decades considered to be planets. Between then and around 1851, when the number of planets had reached 23, astronomers started using the asteroid for the smaller bodies. With the discovery of Pluto in 1930, most astronomers considered the Solar System to have nine planets and it was roughly one-twentieth the mass of Mercury, which made Pluto by far the smallest planet. Although it was more than ten times as massive as the largest object in the asteroid belt, Ceres. In the 1990s, astronomers began to find objects in the region of space as Pluto. Many of these shared several of Plutos key orbital characteristics, and Pluto started being seen as the largest member of a new class of objects and this led some astronomers to stop referring to Pluto as a planet. Several terms, including subplanet and planetoid, started to be used for the now known as dwarf planets. By 2005, three trans-Neptunian objects comparable in size to Pluto had been reported and it became clear that either they would also have to be classified as planets, or Pluto would have to be reclassified. Astronomers were also confident that more objects as large as Pluto would be discovered, Eris was discovered in January 2005, it was thought to be slightly larger than Pluto, and some reports informally referred to it as the tenth planet. As a consequence, the became a matter of intense debate during the IAU General Assembly in August 2006. The IAUs initial draft proposal included Charon, Eris, and Ceres in the list of planets, dropping Charon from the list, the new proposal also removed Pluto, Ceres, and Eris, because they have not cleared their orbits. The IAUs final Resolution 5A preserved this three-category system for the bodies orbiting the Sun

Oceanic climate
–
Oceanic climates are defined as having a monthly mean temperature below 22 °C in the warmest month, and above 0 °C in the coldest month. It typically lacks a dry season, as precipitation is evenly dispersed throughout the year. Oceanic climates generally have cool summers and mild to cool winters, Oceanic climates are most dominant in Europe, where they spread much farther inland than in other continents. Oceanic climates can have much storm activity as they are located in the belt of the stormy westerlies, many oceanic climates have frequent cloudy or overcast conditions due to the near constant storms and lows tracking over or near them. Precipitation is both adequate and reliable throughout the year in oceanic climates, extended months of rain and cloudy conditions are common in oceanic climates. Seattle is an example of this, between October and May, Seattle experiences high rainfall and is mostly or partly cloudy six out of every seven days. In most areas with a climate, precipitation comes in the form of rain for the majority of the year. However, some areas with this climate see some snowfall annually during winter, outside of Australia and parts of New Zealand, most areas with an oceanic climate experience at least one snowstorm per year. In the poleward locations of the climate zone, snowfall is more frequent. Overall temperature characteristics of the oceanic climates feature cool temperatures and infrequent extremes of temperature, summers are cool, with the warmest month having a mean temperature below 22 °C. Poleward of the latter is a zone of the subpolar oceanic climate, with long and cold winters and cool. Examples of this climate include parts of coastal Iceland in the Northern Hemisphere and extreme southern Chile, Oceanic climates are not necessarily always found in coastal locations on the aforementioned parallels, however, in most cases oceanic climates parallel higher middle latitude oceans. The polar jet stream, which moves in a west to east direction across the middle latitudes, advancing low pressure systems, storms, in coastal areas of the higher middle latitudes, the prevailing onshore flow creates the basic structure of most oceanic climates. Oceanic climates are a product and reflection of the adjacent to them. In summer, high pressure pushes the prevailing westerlies north of many oceanic climates. As a result of the Gulf Stream, west-coast areas located in high latitudes like Ireland, the UK, Oceanic climates in Europe occur mostly in Northwest Europe, from Ireland and Great Britain eastward to central Europe. Most of France, Germany, Norway, the north coast of Spain, examples of oceanic climates are found in London, Bergen, Dublin, Berlin, Bilbao, Donostia-San Sebastian, Biarritz, Bayonne, Zürich, Copenhagen and Paris. With decreasing distance to the Mediterranean Sea, the climate of Northwest Europe gradually changes to the subtropical dry-summer or Mediterranean climate of southern Europe

Precipitation
–
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravity. The main forms of precipitation include drizzle, rain, sleet, snow, graupel, Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor, so that the water condenses and precipitates. Thus, fog and mist are not precipitation but suspensions, because the vapor does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated, Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called showers, moisture that is lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be condensed into clouds and rain. This process is active when freezing rain is occurring. A stationary front is often present near the area of freezing rain, provided necessary and sufficient atmospheric moisture content, the moisture within the rising air will condense into clouds, namely stratus and cumulonimbus. Eventually, the droplets will grow large enough to form raindrops. Lake-effect snowfall can be locally heavy, thundersnow is possible within a cyclones comma head and within lake effect precipitation bands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation, on the leeward side of mountains, desert climates can exist due to the dry air caused by compressional heating. The movement of the trough, or intertropical convergence zone. Precipitation is a component of the water cycle, and is responsible for depositing the fresh water on the planet. Approximately 505,000 cubic kilometres of water falls as precipitation each year,398,000 cubic kilometres of it over the oceans and 107,000 cubic kilometres over land. Given the Earths surface area, that means the globally averaged annual precipitation is 990 millimetres, Climate classification systems such as the Köppen climate classification system use average annual rainfall to help differentiate between differing climate regimes. Precipitation may occur on celestial bodies, e. g. when it gets cold, Mars has precipitation which most likely takes the form of frost. Precipitation is a component of the water cycle, and is responsible for depositing most of the fresh water on the planet. Approximately 505,000 km3 of water falls as precipitation each year,398,000 km3 of it over the oceans, given the Earths surface area, that means the globally averaged annual precipitation is 990 millimetres. Mechanisms of producing precipitation include convective, stratiform, and orographic rainfall, Precipitation can be divided into three categories, based on whether it falls as liquid water, liquid water that freezes on contact with the surface, or ice

Sunshine duration
–
It is a general indicator of cloudiness of a location, and thus differs from insolation, which measures the total energy delivered by sunlight over a given period. Sunshine duration is usually expressed in hours per year, or in hours per day, the first measure indicates the general sunniness of a location compared with other places, while the latter allows for comparison of sunshine in various seasons in the same location. Another often-used measure is percentage ratio of recorded bright sunshine duration, an important use of sunshine duration data is to characterize the climate of sites, especially of health resorts. This also takes account the psychological effect of strong solar light on human well-being. It is often used to promote tourist destinations, if the Sun were to be above the horizon 50% of the time for a standard year consisting of 8,760 hours, apparent maximal daytime duration would be 4,380 hours for any point on Earth. However, there are physical and astronomical effects that change that picture, namely, atmospheric refraction allows the Sun to be still visible even when it physically sets below the horizon. For that reason, average daytime is longest in polar areas, places on the Arctic Circle have the longest total annual daytime,4,647 hours, while the North Pole receives 4,575. Because of elliptic nature of the Earths orbit, the Southern Hemisphere is not symmetrical, the Equator has a total daytime of 4,422 hours per year. Given the theoretical maximum of daytime duration for a given location, bright sunshine hours represent the total hours when the sunlight is stronger than a specified threshold, as opposed to just visible hours. Visible sunshine, for example, occurs around sunrise and sunset, measurement is performed by instruments called sunshine recorders. For the specific purpose of sunshine duration recording, Campbell–Stokes recorders are used, when the intensity exceeds a pre-determined threshold, the tape burns. The total length of the trace is proportional to the number of bright hours. Another type of recorder is the Jordan sunshine recorder, newer, electronic recorders have more stable sensitivity than that of the paper tape. In 2003, the duration was finally defined as the period during which direct solar irradiance exceeds a threshold value of 120 W/m². The sky is clear in these regions, and fair weather is virtually perpetual, the descending branch of the Hadley cell and the long-term lack of atmospheric disturbances helps to explain the seemingly endless supply of sunny, cloud-free days in the deserts. Low clouding conditions are associated with rainfall shortage, as seen in these dry regions. In the belt encompassing northern Chad and the Tibesti Mountains, northern Sudan, southern Libya, some places in the interior of the Arabian Peninsula receive 3, 600–3,800 hours of bright sunshine annually. The largest sun-baked region in the world is North Africa, the sunniest month in the world is December in Eastern Antarctica, with almost 23 hours of bright sun daily

Kiteboarding
–
Kiteboarding is a surface water sport combining aspects of wakeboarding, snowboarding, windsurfing, surfing, paragliding, skateboarding and gymnastics into one extreme sport. Kitesurfing is a style of kiteboarding specific to wave riding, which utilizes standard surfboards or boards shaped specifically for the purpose, there are different styles of kiteboarding, including freestyle, freeride, downwinders, speed, course racing, wakestyle, jumping and kitesurfing in the waves. In 2012, the number of kitesurfers was estimated by the ISAF, the global market for kite gear sales is worth US $250 million. In the 1800s, George Pocock used kites of increased size to propel carts on land and ships on the water, both carts and boats were able to turn and sail upwind. The kites could be flown for sustained periods, the intention was to establish kitepower as an alternative to horsepower, partly to avoid the hated horse tax that was levied at that time. In 1978, Ian Days FlexiFoil kite-powered Tornado catamaran exceeded 40 km/h, in October 1977 Gijsbertus Adrianus Panhuise received the first patent for KiteSurfing. Although this patent did not result in any commercial interest, Gijsbertus Adrianus Panhuise could be considered as the originator of KiteSurfing, through the 1980s, there were occasionally successful attempts to combine kites with canoes, ice skates, snow skis, water skis and roller skates. Strasilla and his Swiss friend Andrea Kuhn used this invention also in combination with surfboards and snowboards, grasskies, one of his patents describes in 1979 the first use of an inflatable kite design for kitesurfing. In 1990, practical kite buggying was pioneered by Peter Lynn at Argyle Park in Ashburton, Lynn coupled a three-wheeled buggy with a forerunner of the modern parafoil kite. Kite buggying proved to be very popular worldwide, with over 14,000 buggies sold up to 1999, the development of modern-day kitesurfing by the Roeselers in the USA and the Legaignoux in France carried on in parallel to buggying. The KiteSki was commercially available in 1994, the kite had a rudimentary water launch capability and could go upwind. In 1995, Cory Roeseler visited Peter Lynn at New Zealands Lake Clearwater in the Ashburton Alpine Lakes area, demonstrating speed, balance, in the late 1990s, Corys ski evolved to a single board similar to a surfboard. Bruno Legaignoux has continued to improve kite designs, including developing the bow kite design, in 1997, specialized kite boards were developed by Raphaël Salles and Laurent Ness. By the end of 1998 kitesurfing had become a sport, distributed and taught through a handful group of shops. The first competition was held on Maui in September 1998 and won by Flash Austin, starting in 1999, kitesurfing became a mainstream sport with the entry of key windsurfing manufacturers namely Naish and Neil Pryde. Single direction boards derived from windsurfing and surfing designs became the dominant form of kiteboard, from 2001 onwards, twin-tip bi-directional boards became more popular for most flat water riders, with directional boards still in use for surf conditions. In May 2012, the racing style of kitesurfing was announced as a sport for the 2016 Rio Olympics. Kitesurfing was named as an event at the 2018 Summer Youth Olympics in Buenos Aires

Windsurfing
–
Windsurfing is a surface water sport that combines elements of surfing and sailing. It consists of a board usually 2.5 to 3 meters long, the rig is connected to the board by a free-rotating universal joint and consists of a mast, 2-sided boom and sail. The sail area generally ranges from 2.5 m2 to 12 m2 depending on the conditions, the skill of the sailor, the type of windsurfing being undertaken and the weight of the person windsurfing. Some credits S. Newman Darby with the origination of windsurfing by 1964 on the Susquehanna River, Pennsylvania, USA when he invented the sailboard, in 1964, Darby began selling his sailboards. A promotional article by Darby was published in the August 1965 edition of Popular Science magazine, while Darbys sailboard incorporated a pivoting rig, it was square rigged and suffered all the associated limitations. You operated the sailboard with your back to the lee side of the kite shaped square sail, Although it might be considered a minimalistic version of a sailboat, windsurfing offers experiences that are outside the scope of other sailing craft designs. Windsurfers can perform jumps, inverted loops, spinning maneuvers, extreme waves aside, many expert windsurfers will ride the same waves as surfers do. At one time referred to as surfings ginger haired cousin by the legendary champion, Robby Naish. As a result of attempts to claim the word windsurfer as a trademark, participants have been encouraged to use different names to describe the sport, the term windsurfing has persisted as the accepted name for the sport, and the word windsurfer persists for both participants and equipment. Windsurfing is predominately undertaken on a non-competitive basis, organised competition does take place at all levels across the world, including in the Olympics. Typical formats for competitive windsurfing include Formula Windsurfing, speed sailing, slalom, course racing, wave sailing, superX, the boom of the 1980s led windsurfing to be recognized as an Olympic sport in 1984. However, windsurfings popularity saw a decline in the mid-1990s, thanks to licensing battles. The sport experienced a modest revival, as new beginner-friendly designs became available, further pressure came as a proportion of avid windsurfers took up the similar sport of kitesurfing. Windsurfing, as a sport and recreational activity, did not emerge until the half of the 20th century. Darby did not file a patent for the sailboard, however, he is widely recognized as its inventor as well as the first to conceive, design, and build a sailboard with a universal joint. In 1964, Darby began selling his sailboards, twelve-year-old Peter Chilvers is often cited for inventing a sailboard in 1958. In the 1960s, Jim Drake was the first to many problems of getting the board to sail while Hoyle Schweitzer was the first to be successful in marketing the sailboard. That night they developed the idea of a kite-powered surfboard, on later reflection, Drake didnt like the integrity of the idea and dismissed it

Underwater diving
–
Underwater diving is the practice of descending below the waters surface to conduct underwater activities. The saturation diving technique reduces the risk of decompression sickness after long duration deep dives, Atmospheric diving suits may be used to isolate the diver from the effects of high ambient pressure. Although not usually considered to be diving, crewed submersibles can extend depth range, Diving is also restricted to conditions which are not excessively hazardous, though the level of risk acceptable to the diver can vary considerably. Occasionally diving may be done in other than water. Recreational diving, sometimes called sport diving or subaquatics, is a leisure activity. Technical diving is a form of diving that achieves greater depths or endurance in more challenging conditions. Professional diving takes a range of diving activities to the work site. Public safety diving is the work done by law enforcement, fire rescue, and search & rescue/recovery dive teams. Military diving includes combat diving, clearance diving and ships husbandry diving, underwater sports is a group of competitive sports using either free-diving, snorkeling or scuba technique, or a combination of these techniques. The term deep sea diving refers to underwater diving, usually with surface supplied equipment, hard hat diving is any form of diving with a helmet, including the standard copper helmet, and other forms of free-flow and lightweight demand helmets. There are several modes of diving based on the equipment used. The ability to dive and swim underwater while holding ones breath is considered a useful skill, an important part of water sport and Navy safety training. Underwater diving without breathing apparatus can be categorized as underwater swimming, snorkeling and freediving. Several competitive underwater sports are practiced without breathing apparatus, freediving precludes the use of external breathing devices, and relies on the ability of divers to hold their breath until resurfacing. The technique ranges from simple breath-hold diving to competitive apnea dives, fins and a diving mask are often used in free diving to improve vision and provide more efficient propulsion. A short breathing tube called a snorkel allows the diver to breathe at the surface while the face is immersed, snorkeling on the surface with no intention of diving is a popular water sport and recreational activity. Scuba diving is diving with an underwater breathing apparatus, which is completely independent of surface supply. Scuba provides the diver with the advantages of mobility and horizontal range far beyond the reach of a hose attached to surface-supplied diving equipment

Nordic walking
–
Nordic walking is a total body version of walking that can be enjoyed both by non-athletes as a health-promoting physical activity, and by athletes as a sport. The activity is performed with specially designed walking poles similar to ski poles, Nordic walking is fitness walking with specially designed poles. While trekkers, backpackers and skiers had been using the concept for decades. Nordic Walkings concept was developed on the basis of off-season ski-training activity while using one-piece ski poles, for decades hikers and backpackers used their one-piece ski poles long before trekking and Nordic walking poles came onto the scene. Ski racers deprived of snow have always used and still do use their one-piece ski poles for ski walking, the first poles specially designed and marketed to fitness walkers were produced by Exerstrider of the USA in 1988. Nordic Walker poles were produced and marketed by Exel in 1997, Exel coined and popularized the term Nordic Walking in 1999. Compared to regular walking, Nordic walking involves applying force to the poles with each stride, Nordic walking has been estimated as producing up to a 46% increase in energy consumption, compared to walking without poles. According to the findings of the research, conducted by the scientists from various universities*. The key points stated by the authors are, Nordic walking, conventional walking. •Nordic walking and conventional walking both improve cardio-respiratory fitness while resistance training does not, •Nordic walking provides additional benefits in upper-body muscular strength compared to conventional walking. •Nordic walking is an effective and efficient mode of exercise to improve overall fitness in older adults,2013 Nordic walking poles are significantly shorter than those recommended for cross-country skiing. Nordic walking poles come in one-piece, non-adjustable shaft versions, available in varying lengths, one piece poles are generally stronger and lighter, but must be matched to the user. Telescoping poles are one-size fits all, and are more transportable, Nordic walking poles feature a range of grips and wrist-straps, or rarely, no wrist-strap at all. The straps eliminate the need to tightly grasp the grips, as with many trekking poles, Nordic walking poles come with removable rubber tips for use on hard surfaces and hardened metal tips for trails, the beach, snow and ice. Most poles are made from aluminium, carbon fiber, or composite materials. Special walking shoes are not required, although there are shoes being marketed as specifically designed for the sport, the cadences of the arms, legs and body are, rhythmically speaking, similar to those used in normal, vigorous, walking. The range of arm movement regulates the length of the stride, restricted arm movements will mean a natural restricted pelvic motion and stride length. The longer the pole thrust, the longer the stride and more powerful the swing of the pelvis, trekking pole Walking stick Media related to Nordic walking at Wikimedia Commons

Ernst Heinkel
–
Dr. Ernst Heinkel was a German aircraft designer, manufacturer, Wehrwirtschaftsführer in the Third Reich, and member of the Nazi party. His company Heinkel Flugzeugwerke produced the Heinkel He 178, the worlds first turbojet aircraft and jet plane, and the Heinkel He 176 and he was awarded the German National Prize for Art and Science in 1938. He was born in Grunbach, today a part of Remshalden, as a young man he became an apprentice machinist at a foundry. He determined flight was the future of transportation, and the year, he built his first aircraft. Heinkel crashed the plane in 1911 and suffered severe injuries, soon afterwards, he gained employment at Luft-Verkehrs Gesellschaft, who were building Farman aircraft. From there, he went to Albatros and his planes were used by the Austro-Hungarian army and Germanys Kaiserliche Marine during the war. After leaving the Albatros, Heinkel designed several land- and seaplanes for the Hansa-Brandenburg company starting in 1914, in 1921, Heinkel was appointed head designer of the recently re-established Caspar-Werke, but soon left after a dispute over ownership of a design. In 1922 he established the Heinkel-Flugzeugwerke company at Warnemünde and he installed a similar catapult on the ocean liner Bremen for launching mail planes. Japan was part of the inspection commission, Heinkel hid his aircraft in dunes behind his plant and were never discovered during inspections. Heinkel noted in his memoirs that his companys relationship with Japan in the 1920s led to decades of cooperation, after Adolf Hitler came to power, designs by Heinkels firm formed a vital part of the Luftwaffes growing strength in the years leading up to the Second World War. This included the Heinkel He 59, the Heinkel He 115 and he was designated a Wehrwirtschaftführer by the German government for his commitment to rearmament. Heinkel was passionate about high-speed flight, and was keen on exploring alternative forms of aircraft propulsion, in 1942 the government nationalised the Heinkel works. In practice, this meant that Heinkel was detained until he sold his controlling interest in his factories to Hermann Göring and it was at the Heinkel-Sud offices that Dr. With Germany forbidden from manufacturing aircraft by the Allies, Heinkel used his companys facilities to private transportation. In 1953 Heinkel began production of the Tourist scooter, followed by the Perle moped in 1954, in 1956 he introduced the Heinkel Kabine bubble car. Bubble car and moped production ceased shortly after the restriction on aircraft manufacture was lifted, Ernst Heinkel died in 1958 in Stuttgart. His autobiography, Stürmisches Leben, was published in 1956 and translated into English as He1000 in its British edition and Stormy Life, the First Jet Pilot - The Story of German Test Pilot Erich Warsitz. English Edition Audio commentary by Erich Warsitz about Ernst Heinkel, Switzerland, August 2,1979

NSDAP
–
Its precursor, the German Workers Party, existed from 1919 to 1920. The party emerged from the German nationalist, racist, and populist Freikorps paramilitary culture, the party was created as a means to draw workers away from communism and into völkisch nationalism. Pseudo-scientific racism theories were central to Nazism, the Nazis propagated the idea of a peoples community. Their aim was to unite racially desirable Germans as national comrades, while excluding those deemed either to be political dissidents, to maintain the supposed purity and strength of the Aryan race, the Nazis sought to exterminate Jews, Romani, and the physically and mentally handicapped. They imposed exclusionary segregation on homosexuals, Africans, Jehovahs Witnesses, the partys leader since 1921, Adolf Hitler, was appointed Chancellor of Germany by President Paul von Hindenburg on 30 January 1933. Hitler rapidly established a regime known as the Third Reich. The term Nazi derives from the name given in German to a party member Nationalsozialist and was coined in response to the German term Sozi, members of the party referred to themselves as Nationalsozialisten, rarely as Nazis. The term Parteigenosse was commonly used among Nazis, with the feminine form Parteigenossin used when it was appropriate, the term was in use before the rise of the party as a colloquial and derogatory word for a backward peasant, characterising an awkward and clumsy person. It derived from Ignaz, being a version of Ignatius, a common name in Bavaria. Opponents seized on this and shortened the name in intentional association to the long-time existing Sozi to the dismissive Nazi. In 1933, when Adolf Hitler assumed power of the German government, usage of the designation Nazi diminished in Germany, the use of Nazi Germany, and Nazi regime, was popularised by anti-Nazis and German exiles abroad. Thereafter, the spread into other languages and eventually was brought back to Germany after the Second World War. The party grew out of political groups with a nationalist orientation that formed in the last years of World War I. In 1918, a called the Freien Arbeiterausschuss für einen guten Frieden was created in Bremen. On 7 March 1918, Anton Drexler, an avid German nationalist, Drexler saw the situation of political violence and instability in Germany as the result of the new Weimar Republic being out-of-touch with the masses, especially the lower classes. These were all well-known themes popular with various Weimar paramilitary groups such as the Freikorps, though very small, Drexlers movement did receive attention and support from some influential figures. Supporter Dietrich Eckhart brought military figure Count Felix Graf von Bothmer, later in 1918, Karl Harrer, convinced Drexler and several others to form the Politischer Arbeiterzirkel. The members met periodically for discussions with themes of nationalism and racism directed against the Jews and they became one of many völkisch movements that existed in Germany at the time

International Standard Book Number
–
The International Standard Book Number is a unique numeric commercial book identifier. An ISBN is assigned to each edition and variation of a book, for example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, the method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country. The initial ISBN configuration of recognition was generated in 1967 based upon the 9-digit Standard Book Numbering created in 1966, the 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108. Occasionally, a book may appear without a printed ISBN if it is printed privately or the author does not follow the usual ISBN procedure, however, this can be rectified later. Another identifier, the International Standard Serial Number, identifies periodical publications such as magazines, the ISBN configuration of recognition was generated in 1967 in the United Kingdom by David Whitaker and in 1968 in the US by Emery Koltay. The 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108, the United Kingdom continued to use the 9-digit SBN code until 1974. The ISO on-line facility only refers back to 1978, an SBN may be converted to an ISBN by prefixing the digit 0. For example, the edition of Mr. J. G. Reeder Returns, published by Hodder in 1965, has SBN340013818 -340 indicating the publisher,01381 their serial number. This can be converted to ISBN 0-340-01381-8, the check digit does not need to be re-calculated, since 1 January 2007, ISBNs have contained 13 digits, a format that is compatible with Bookland European Article Number EAN-13s. An ISBN is assigned to each edition and variation of a book, for example, an ebook, a paperback, and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, a 13-digit ISBN can be separated into its parts, and when this is done it is customary to separate the parts with hyphens or spaces. Separating the parts of a 10-digit ISBN is also done with either hyphens or spaces, figuring out how to correctly separate a given ISBN number is complicated, because most of the parts do not use a fixed number of digits. ISBN issuance is country-specific, in that ISBNs are issued by the ISBN registration agency that is responsible for country or territory regardless of the publication language. Some ISBN registration agencies are based in national libraries or within ministries of culture, in other cases, the ISBN registration service is provided by organisations such as bibliographic data providers that are not government funded. In Canada, ISBNs are issued at no cost with the purpose of encouraging Canadian culture. In the United Kingdom, United States, and some countries, where the service is provided by non-government-funded organisations. Australia, ISBNs are issued by the library services agency Thorpe-Bowker

OCLC
–
The Online Computer Library Center is a US-based nonprofit cooperative organization dedicated to the public purposes of furthering access to the worlds information and reducing information costs. It was founded in 1967 as the Ohio College Library Center, OCLC and its member libraries cooperatively produce and maintain WorldCat, the largest online public access catalog in the world. OCLC is funded mainly by the fees that libraries have to pay for its services, the group first met on July 5,1967 on the campus of the Ohio State University to sign the articles of incorporation for the nonprofit organization. The group hired Frederick G. Kilgour, a former Yale University medical school librarian, Kilgour wished to merge the latest information storage and retrieval system of the time, the computer, with the oldest, the library. The goal of network and database was to bring libraries together to cooperatively keep track of the worlds information in order to best serve researchers and scholars. The first library to do online cataloging through OCLC was the Alden Library at Ohio University on August 26,1971 and this was the first occurrence of online cataloging by any library worldwide. Membership in OCLC is based on use of services and contribution of data, between 1967 and 1977, OCLC membership was limited to institutions in Ohio, but in 1978, a new governance structure was established that allowed institutions from other states to join. In 2002, the structure was again modified to accommodate participation from outside the United States. As OCLC expanded services in the United States outside of Ohio, it relied on establishing strategic partnerships with networks, organizations that provided training, support, by 2008, there were 15 independent United States regional service providers. OCLC networks played a key role in OCLC governance, with networks electing delegates to serve on OCLC Members Council, in early 2009, OCLC negotiated new contracts with the former networks and opened a centralized support center. OCLC provides bibliographic, abstract and full-text information to anyone, OCLC and its member libraries cooperatively produce and maintain WorldCat—the OCLC Online Union Catalog, the largest online public access catalog in the world. WorldCat has holding records from public and private libraries worldwide. org, in October 2005, the OCLC technical staff began a wiki project, WikiD, allowing readers to add commentary and structured-field information associated with any WorldCat record. The Online Computer Library Center acquired the trademark and copyrights associated with the Dewey Decimal Classification System when it bought Forest Press in 1988, a browser for books with their Dewey Decimal Classifications was available until July 2013, it was replaced by the Classify Service. S. The reference management service QuestionPoint provides libraries with tools to communicate with users and this around-the-clock reference service is provided by a cooperative of participating global libraries. OCLC has produced cards for members since 1971 with its shared online catalog. OCLC commercially sells software, e. g. CONTENTdm for managing digital collections, OCLC has been conducting research for the library community for more than 30 years. In accordance with its mission, OCLC makes its research outcomes known through various publications and these publications, including journal articles, reports, newsletters, and presentations, are available through the organizations website. The most recent publications are displayed first, and all archived resources, membership Reports – A number of significant reports on topics ranging from virtual reference in libraries to perceptions about library funding

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Integrated Authority File
–
The Integrated Authority File or GND is an international authority file for the organisation of personal names, subject headings and corporate bodies from catalogues. It is used mainly for documentation in libraries and increasingly also by archives, the GND is managed by the German National Library in cooperation with various regional library networks in German-speaking Europe and other partners. The GND falls under the Creative Commons Zero license, the GND specification provides a hierarchy of high-level entities and sub-classes, useful in library classification, and an approach to unambiguous identification of single elements. It also comprises an ontology intended for knowledge representation in the semantic web, available in the RDF format

Virtual International Authority File
–
The Virtual International Authority File is an international authority file. It is a joint project of national libraries and operated by the Online Computer Library Center. The project was initiated by the US Library of Congress, the German National Library, the National Library of France joined the project on October 5,2007. The project transitions to a service of the OCLC on April 4,2012, the aim is to link the national authority files to a single virtual authority file. In this file, identical records from the different data sets are linked together, a VIAF record receives a standard data number, contains the primary see and see also records from the original records, and refers to the original authority records. The data are available online and are available for research and data exchange. Reciprocal updating uses the Open Archives Initiative Protocol for Metadata Harvesting protocol, the file numbers are also being added to Wikipedia biographical articles and are incorporated into Wikidata. VIAFs clustering algorithm is run every month, as more data are added from participating libraries, clusters of authority records may coalesce or split, leading to some fluctuation in the VIAF identifier of certain authority records
