The biggest city on the river Rhine is Cologne, Germany with a population of more than 1,050,000 people. It is the second-longest river in Central and Western Europe (after the Danube), at about 1,230 km (760 mi),[note 2][note 1] with an average discharge of about 2,900 m3/s (100,000 cu ft/s).
Document 2: Hawk Mountain: Hawk Mountain is a mountain ridge, part of the Blue Mountain Ridge in the Appalachian Mountain chain, located in central-eastern Pennsylvania near Reading and Allentown. The area includes 13,000 acres of protected private and public land, including the 2,600 acre Hawk Mountain Sanctuary.
Document 3: Johann Peter Gogarten: Johann Peter Gogarten is a German-American biologist studying the early evolution of life. Born in Bad Oeynhausen, Germany, he studied plant physiology and membrane transport with Friedrich-Wilhelm Bentrup in Tübingen and Giessen. In 1987 he moved to the US as a postdoc to work with Lincoln Taiz at UC Santa Cruz. He currently is Distinguished Professor of Molecular and Cell Biology at the University of Connecticut in Storrs, CT.
Document 4: Rhine: Between Bingen and Bonn, the Middle Rhine flows through the Rhine Gorge, a formation which was created by erosion. The rate of erosion equaled the uplift in the region, such that the river was left at about its original level while the surrounding lands raised. The gorge is quite deep and is the stretch of the river which is known for its many castles and vineyards. It is a UNESCO World Heritage Site (2002) and known as "the Romantic Rhine", with more than 40 castles and fortresses from the Middle Ages and many quaint and lovely country villages.
Document 5: David Peak: David Peak is Professor of Physics at Utah State University. His current research focuses on the interdisciplinary field of complexity and computation in biological phenomena, motivated by the similarities between stomata and cellular automata. Peak was one founder of the National Council on Undergraduate Research and is on the governing board (formerly the Chair) of the National Conferences on Undergraduate Research.
Document 6: Feigenbaumklippe: The Feigenbaumklippe is a rock formation in the Oker valley in the Harz mountains of central Germany. They lie on the hiking trail from the "Kästeklippen" crags to Romkerhall Waterfall. These granite rocks, which show clear signs of "wool sack weathering" ("Wollsackverwitterung") are a favourite destination for hikers and offer a good view of the valley towards the west. The observation point has safety railings.
Document 7: Eckehard Specht: Eckehard Specht is a professor in Otto von Guericke University, Magdeburg, Germany. He belongs to Institute of Fluid Dynamics and Thermodynamics (ISUT) department. His specializations are Combustion technology, heat and mass transfer, chemical process engineering, global warming, and ceramic materials.
Document 8: Taubenklippe: The Taubenklippe is a rock formation in the Harz mountains in the German state of Saxony-Anhalt. It lies about halfway between Bad Harzburg and Ilsenburg at a height of on the eastern slopes of the Ecker valley. From the crag there is a good view over Harz Foreland, the heights near Bad Harzburg and the highest mountain in the Har, the Brocken. The "Taubenklippe" may be reached from the Ecker valley on a footpath, some 6 km long, that starts in Ilsenburg.
Document 9: Jörg-Peter Ewert: From 1958 to 1965 Jörg-Peter Ewert studied the specialties biology, chemistry, and geography at the University of Göttingen. He graduated in 1965 and took up the specialty of zoology under the direction of the behavior physiologist Georg Birukow. The subject of Ewert’s PhD (Dr.rer.nat.) dissertation was: "The influence of peripheral sensory and central nervous system responses on the readiness of the orienting movement in the common toad". Later he passed the state examination for the lecturing at secondary schools.
Document 10: Habichtswand: The Habichtwand is a rock formation located in the city of Bad Oeynhausen and the district of Minden-Lübbecke within the German state of North Rhine-Westphalia, not far from the city of Minden. The rock is located in the Wiehen Hills. The meaning of the German term "Habichtswand" is "Wall of the Northern Goshawk".
Document 11: Rhine: Until the early 1980s, industry was a major source of water pollution. Although many plants and factories can be found along the Rhine up into Switzerland, it is along the Lower Rhine that the bulk of them are concentrated, as the river passes the major cities of Cologne, Düsseldorf and Duisburg. Duisburg is the home of Europe's largest inland port and functions as a hub to the sea ports of Rotterdam, Antwerp and Amsterdam. The Ruhr, which joins the Rhine in Duisburg, is nowadays a clean river, thanks to a combination of stricter environmental controls, a transition from heavy industry to light industry and cleanup measures, such as the reforestation of Slag and brownfields. The Ruhr currently provides the region with drinking water. It contributes 70 m3/s (2,500 cu ft/s) to the Rhine. Other rivers in the Ruhr Area, above all, the Emscher, still carry a considerable degree of pollution.
Document 12: Falkenfelsen: The Falkenfelsen (Falcon Rock) is a granite rock formation in the Northern Black Forest of Germany's Baden-Württemberg state. One side of the formation is a cliff about high. From the Schwarzwaldhochstrasse (Black Forest Highway), two hiking trails lead through the formation and end at the shelter Herta-hut. The platform has a view over the northern Black Forest, with the Hornisgrinde in the south, Bühlerhöhe in the northeast and the valley of the Upper Rhine on the west.
Document 13: Ursula Goodenough: Ursula Goodenough, daughter of Erwin Ramsdell Goodenough and Evelyn Goodenough Pitcher, earned a B.A. in zoology from Barnard College, an M.A. in zoology at Columbia University and her Ph.D. in Biology at Harvard University. She was an assistant and associate professor of biology at Harvard from 1971-1978 before moving to Washington University. She wrote three editions of a widely adopted textbook, "Genetics". She served as president of The American Society for Cell Biology in 1984-85, was elected to the Cellular and Developmental Biology section of the American Academy of Arts and Sciences in 2009, and elected a Fellow of the American Society for Microbiology in 2013.
Document 14: Rhine: In the centre of Basel, the first major city in the course of the stream, is located the "Rhine knee"; this is a major bend, where the overall direction of the Rhine changes from West to North. Here the High Rhine ends. Legally, the Central Bridge is the boundary between High and Upper Rhine. The river now flows North as Upper Rhine through the Upper Rhine Plain, which is about 300 km long and up to 40 km wide. The most important tributaries in this area are the Ill below of Strasbourg, the Neckar in Mannheim and the Main across from Mainz. In Mainz, the Rhine leaves the Upper Rhine Valley and flows through the Mainz Basin.
Document 15: Rhine: The Lower Rhine flows through North Rhine-Westphalia. Its banks are usually heavily populated and industrialized, in particular the agglomerations Cologne, Düsseldorf and Ruhr area. Here the Rhine flows through the largest conurbation in Germany, the Rhine-Ruhr region. One of the most important cities in this region is Duisburg with the largest river port in Europe (Duisport). The region downstream of Duisburg is more agricultural. In Wesel, 30 km downstream of Duisburg, is located the western end of the second east-west shipping route, the Wesel-Datteln Canal, which runs parallel to the Lippe. Between Emmerich and Cleves the Emmerich Rhine Bridge, the longest suspension bridge in Germany, crosses the 400 m wide river. Near Krefeld, the river crosses the Uerdingen line, the line which separates the areas where Low German and High German are spoken.
