St. Louis
–
St. Louis is an independent city and major U. S. port in the state of Missouri, built along the western bank of the Mississippi River, on the border with Illinois. Prior to European settlement, the area was a regional center of Native American Mississippian culture. The city of St. Louis was founded in 1764 by French fur traders Pierre Laclède and Auguste Chouteau, in 1764, following Frances defeat in the Seven Years War, the area was ceded to Spain and retroceded back to France in 1800. In 1803, the United States acquired the territory as part of the Louisiana Purchase, during the 19th century, St. Louis developed as a major port on the Mississippi River. In the 1870 Census, St. Louis was ranked as the 4th-largest city in the United States and it separated from St. Louis County in 1877, becoming an independent city and limiting its own political boundaries. In 1904, it hosted the Louisiana Purchase Exposition and the Summer Olympics, the economy of metro St. Louis relies on service, manufacturing, trade, transportation of goods, and tourism. This city has become known for its growing medical, pharmaceutical. St. Louis has 2 professional sports teams, the St. Louis Cardinals of Major League Baseball, the city is commonly identified with the 630-foot tall Gateway Arch in Downtown St. Louis. The area that would become St. Louis was a center of the Native American Mississippian culture and their major regional center was at Cahokia Mounds, active from 900 AD to 1500 AD. Due to numerous major earthworks within St. Louis boundaries, the city was nicknamed as the Mound City and these mounds were mostly demolished during the citys development. Historic Native American tribes in the area included the Siouan-speaking Osage people, whose territory extended west, European exploration of the area was first recorded in 1673, when French explorers Louis Jolliet and Jacques Marquette traveled through the Mississippi River valley. Five years later, La Salle claimed the region for France as part of La Louisiane. The earliest European settlements in the area were built in Illinois Country on the east side of the Mississippi River during the 1690s and early 1700s at Cahokia, Kaskaskia, migrants from the French villages on the opposite side of the Mississippi River founded Ste. In early 1764, after France lost the 7 Years War, Pierre Laclède, the early French families built the citys economy on the fur trade with the Osage, as well as with more distant tribes along the Missouri River. The Chouteau brothers gained a monopoly from Spain on the fur trade with Santa Fe, French colonists used African slaves as domestic servants and workers in the city. In 1780 during the American Revolutionary War, St. Louis was attacked by British forces, mostly Native American allies, the founding of St. Louis began in 1763. Pierre Laclede led an expedition to set up a fur-trading post farther up the Mississippi River, before then, Laclede had been a very successful merchant. For this reason, he and his trading partner Gilbert Antoine de St. Maxent were offered monopolies for six years of the fur trading in that area

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

Science museum
–
A science museum is a museum devoted primarily to science. Older science museums tended to concentrate on static displays of objects related to history, paleontology, geology, industry and industrial machinery. Modern trends in museology have broadened the range of subject matter, many if not most modern science museums — which increasingly refer to themselves as science centers or discovery centers — also emphasize technology, and are therefore also technology museums. The mission statements of science centers and modern museums vary, but they are united in being places that make science accessible and they are an integral and dynamic part of the learning environment, promoting exploration from the first Eureka. As early as the Renaissance, many aristocrats collected curiosities for display to their family, universities and particularly medical schools also maintained study collections of specimens for their students. Scientists and collectors displayed their finds in private cabinets of curiosities, such collections were the predecessors of modern natural history museums. The first purpose-built museum covering natural philosophy and open to the public from 1683 was the original Ashmolean museum in Oxford, the first dedicated science museum was the Museo de Ciencias Naturales, in Madrid, Spain. Opened in 1752, it almost disappeared during the Franco regime, the Utrecht University Museum, among others, still displays an extensive collection of 18th-century animal and human rarities in its original setting. Another line in the genealogy of science museums came during the Industrial Revolution, for example, the Great Exhibition in The Crystal Palace eventually gave rise to Londons Science Museum. In America, various Natural History Societies established collections in the early 19th century, notable was the early New England Museum of Natural History, which opened in Boston in 1864. The Academy of Science of Saint Louis was founded in 1856 as the first scientific organization west of the Mississippi, the modern interactive science museum appears to have been pioneered by Munich’s Deutsches Museum in the early 20th century. This museum had moving exhibits where visitors were encouraged to push buttons, the concept was taken to the US by Julius Rosenwald, chairman of Sears, Roebuck and Company, who visited the Deutsches Museum with his young son in 1911. He was so-captivated by the experience that he decided to build a museum in his home town. Chicagos Museum of Science and Industry opened in phases between 1933 and 1940, in 1959 the Museum of Science and Natural History was formally created by the Academy of Science of Saint Louis, featuring many interactive science and history exhibits. In August 1969, Frank Oppenheimer dedicated his new Exploratorium in San Francisco almost completely to interactive science exhibits, the Exploratorium published the details of their own exhibits in Cookbooks that served as an inspiration to many other museums around the world. Opened in September 1969, the Ontario Science Centre continued the trend of featuring interactive exhibits rather than static displays, in 1973, the first Omnimax theater opened as the Reuben H. Fleet Space Theater and Science Center in San Diegos Balboa Park, the tilted-dome Space Theater doubled as a planetarium. The Science Center was an Exploratorium-style museum included as a part of the complex

Planetarium
–
A planetarium is a theatre built primarily for presenting educational and entertaining shows about astronomy and the night sky, or for training in celestial navigation. Whatever technologies are used, the objective is normally to link together to provide an accurate relative motion of the sky. Typical systems can be set to display the sky at any point in time, past or present, planetaria range in size from the Hayden Planetariums 21-meter dome seating 423 people, to three-meter inflatable portable domes where children sit on the floor. Such portable planetaria serve education programs outside of the permanent installations of museums, the term planetarium is sometimes used generically to describe other devices which illustrate the solar system, such as a computer simulation or an orrery. Planetarium software refers to an application that renders a three-dimensional image of the sky onto a two-dimensional computer screen. The term planetarian is used to describe a member of the staff of a planetarium. The ancient Greek polymath Archimedes is attributed with creating a primitive device that could predict the movements of the Sun and the Moon. The discovery of the Antikythera mechanism proved that such devices already existed during antiquity, campanus of Novara described a planetary equatorium in his Theorica Planetarum, and included instructions on how to build one. The Globe of Gottorf built around 1650 had constellations painted on the inside and these devices would today usually be referred to as orreries. In fact, many planetaria today have what are called projection orreries, the small size of typical 18th century orreries limited their impact, and towards the end of that century a number of educators attempted some larger scale simulations of the heavens. The efforts of Adam Walker and his sons are noteworthy in their attempts to fuse theatrical illusions with educational aspirations, walkers Eidouranion was the heart of his public lectures or theatrical presentations. Every Planet and Satellite seems suspended in space, without any support and these devices most probably sacrificed astronomical accuracy for crowd-pleasing spectacle and sensational and awe-provoking imagery. The oldest, still working planetarium can be found in the Dutch town Franeker and it was built by Eise Eisinga in the living room of his house. It took Eisinga seven years to build his planetarium, which was completed in 1781 and this was displayed at the Deutsches Museum in 1924, construction work having been interrupted by the war. The planets travelled along overhead rails, powered by electric motors,180 stars were projected onto the wall by electric bulbs. Atwoods work at the Chicago Academy of Sciences and by the ideas of Walther Bauersfeld, in August 1923, the first Zeiss planetarium projected images of the night sky onto the white plaster lining of a 16 m hemispherical concrete dome, erected on the roof of the Zeiss works. The first official public showing was at the Deutsches Museum in Munich on October 21,1923, when Germany was divided into East and West Germany after the war, the Zeiss firm was also split. Part remained in its headquarters at Jena, in East Germany

Forest Park (St. Louis)
–
Forest Park is a public park located in the western portion of the city of St. Louis, Missouri, United States. It is a prominent civic center and covers 1,371 acres, opened in 1876, more than a decade after its proposal, the park has hosted several significant events, including the Louisiana Purchase Exposition of 1904 and the 1904 Summer Olympics. Since the early-2000s, it has carried out a $100 million restoration of its facilities through a public-private partnership aided by its Master Plan, changes have extended to improving landscaping and habitat as well. The parks acreage includes meadows and trees and a variety of ponds, manmade lakes, for several years, the park has been restoring prairie and wetlands areas of the park. It has reduced flooding and attracted a greater variety of birds and wildlife. An 1864 plan for a park in the city limits was rejected by St. Louis voters. In 1872, St. Louis developer Hiram Leffingwell proposed a 1, the next year another developer, Andrew McKinley, prepared another proposal that met legal challenges. The tract selected that became Forest Park included a heavily forested 1, using McKinleys proposal as a guide, in 1874 the General Assembly passed the Forest Park Act, which established the park and created a county-wide property tax to fund it. In November 1874, the Missouri Supreme Court upheld the new law and referred all questions of land ownership and value to the circuit court. The largest parcels of land needed for the park belonged to Thomas Skinker, Charles P. Chouteau, Julia Maffitt, and William Forsyth, the city purchased the land for a price of $849,058, with another million dollars dedicated to maintenance and improvement. The state of the parkland in 1876 was rural, on the eastern and western edges of the park were unpaved roads. Flowing through the lowlands and turning southeast in the park was the River des Peres. The southwestern part of the park was heavily forested land, a railroad right-of-way cut through the northeast corner of the park. Maximillian G. Kern and Julius Pitzman, the Prussian-born St. Louis Surveyor, the park was dedicated June 24,1876 with a crowd of about 50,000 in attendance. Officials and a band occupied a music stand and podium, and dedicated a statue of Edward Bates, by the early 1890s, streetcar lines reached the park, carrying nearly 3 million visitors a year. After the closing of the city zoo during this period, its animals were moved to a facility in the park, in 1901, Forest Park was selected as the location of the 1904 Worlds Fair, known as the Louisiana Purchase Exposition. The fair opened April 30,1904 and closed December 1,1904, in addition to the fair, the park hosted the diving, swimming, and water polo events for the 1904 Summer Olympics. Fifteen sports offered Olympic competition events, but women could compete only in archery, the 1904 Games were the first time that African Americans were allowed to compete

Thin-shell structure
–
Thin-shell structures are also called plate and shell structures. They are lightweight constructions using shell elements and these elements, typically curved, are assembled to make large structures. Typical applications include aircraft fuselages, boat hulls, and the roofs of large buildings, a thin shell is defined as a shell with a thickness which is small compared to its other dimensions and in which deformations are not large compared to thickness. A primary difference between a structure and a plate structure is that, in the unstressed state, the shell structure has curvature as opposed to the plates structure which is flat. Membrane action in a shell is primarily caused by in-plane forces, where a flat plate acts similar to a beam with bending and shear stresses, shells are analogous to a cable which resists loads through tensile stresses. The ideal thin shell must be capable of developing both tension and compression, all-Russia Exhibition 1896 Diagrid Félix Candela Frei Otto List of thin shell structures Monocoque Stretched grid method Vladimir Shukhov Bechthold, M.

Hyperboloid structure
–
Hyperboloid structures are architectural structures designed using a hyperboloid in one sheet. The first hyperboloid structures were built by Russian engineer Vladimir Shukhov, the worlds first hyperboloid tower is located in Polibino, Dankovsky District, Lipetsk Oblast, Russia. Hyperbolic structures have a negative Gaussian curvature, meaning they curve inward rather than outward or being straight. As doubly ruled surfaces, they can be made with a lattice of beams, hence are easier to build than curved surfaces that do not have a ruling. With cooling towers, a structure is preferred. At the bottom, the widening of the tower provides an area for installation of fill to promote thin film evaporative cooling of the circulated water. In the 1880s, Shukhov began to work on the problem of the design of systems to use a minimum of materials, time. His calculations were most likely derived from mathematician Pafnuty Chebyshevs work on the theory of best approximations of functions, Shukhovs mathematical explorations of efficient roof structures led to his invention of a new system that was innovative both structurally and spatially. The steel gridshells of the pavilions of the 1896 All-Russian Industrial. Two pavilions of this type were built for the Nizhni Novgorod exposition, one oval in plan, the roofs of these pavilions were doubly curved gridshells formed entirely of a lattice of straight angle-iron and flat iron bars. Shukhov himself called them azhurnaia bashnia, the patent of this system, for which Shukhov applied in 1895, was awarded in 1899. Shukhov also turned his attention to the development of an efficient and his solution was inspired by observing the action of a woven basket holding up a heavy weight. Again, it took the form of a curved surface constructed of a light network of straight iron bars. Over the next twenty years, he designed and built close to two hundred of these towers, no two alike, most with heights in the range of 12m to 68m. At least as early as 1911, Shukhov began experimenting with the concept of forming a tower out of stacked sections of hyperboloids. Stacking the sections permitted the form of the tower to taper more at the top, increasing the number of sections would increase the tapering of the overall form, to the point that it began to resemble a cone. By 1918 Shukhov had developed this concept into the design of a nine-section stacked hyperboloid radio transmission tower for Moscow, Shukhov designed a 350m tower, which would have surpassed the Eiffel Tower in height by 50m, while using less than a quarter of the amount of material. In July 1919, Lenin decreed that the tower should be built to a height of 150m, construction of the smaller tower with six stacked hyperboloids began within a few months, and Shukhov Tower was completed by March 1922

Gyo Obata is an American architect, the son of painter Chiura Obata and his wife, Haruko Obata, a floral designer. In 1955, he co-founded global architectural firm HOK and he lives in St. Louis, Missouri and still works in HOKs St. Louis office. C. Obata was born and raised in San Francisco, due to his familys Japanese heritage, he was nearly interned with other Japanese-Americans during World War II. He earned his bachelor of architecture there in 1945. He then studied under master Finnish architect Eero Saarinen at the Cranbrook Academy of Art in Bloomfield Hills, Michigan, receiving his masters degree in architecture and urban design in 1946. Four years later, in 1955, he joined architects George Hellmuth and George Kassabaum in establishing the St. Louis-based architecture firm Hellmuth, Obata and Kassabaum. Due in part to Obatas prowess and growing reputation, the firm achieved global renown, today, HOK has more than 1,800 employees in 23 offices worldwide. In 2010, Obata was featured in a written by Marlene Ann Birkman and published by The Images Publishing Group titled, Gyo Obata. The book features 30 of Obatas projects spanning five decades, Obatas design philosophy is to provide spaces which are not only functional, but also enhance the quality of life for those who work and live in them. In Gyo Obata, Architect | Clients | Reflections, he says that, Obatas national and international projects include, Abraham Lincoln Presidential Library and Museum, Springfield, Illinois Alfred A.

The Missouri History Museum is a history museum located in St. Louis, Missouri in Forest Park showcasing Missouri history. The museum is operated by the Missouri Historical Society and was founded in 1866, in 1988, the Museum joined the Metropolitan Zoological Park and Museum District and began receiving sales tax revenue. In 2000, the Emerson Center, a significant building addition was completed, boosting attendance, the Emerson Center was selected by the American Institute of Architectss Committee on the Environment as an example of architectural design that protects and enhances the environment. It is an example of a green museum, the museums signature collection includes both national artifacts, as well as Missouri and St. Louis. A replica of the Spirit of St. Louis can be found in the museum, a large number of artifacts from the Lewis and Clark Expedition are also housed in the permanent collection, as St. Louis was the starting point for that venture. Admission to the permanent collection is free, however, some exhibitions require the purchase of tickets. 1904 Worlds Fair Charles Lindbergh Missouri History Museum Web Site, Missouri History Museum Online Collections, Missouri History Museum Online Collections

Mounted police
–
Mounted police are police who patrol on horseback or camelback. Some mounted police units are trained in search and rescue due to the ability to travel where vehicles cannot. Poor roads and extensive rural areas made horse-mounted police a necessity in European states until the early 20th century, notable examples included the Royal Canadian Mounted Police, the Mexican Rurales, the British South African Police, the Turkish/Cypriot Zapiteh and the caballeria of the Spanish Civil Guard. Tack used by mounted police is similar to standard riding tack, high-traction horseshoes made of speciality metals or fitted with rubber soles are typically used in urban areas in place of standard steel horseshoes, which are prone to slip on pavement. Rubber soled shoes also produce less noise than steel shoes and jar the hoof less, horses working in riot control wear facial armor, made of perspex so that the animals can still see. The New South Wales Mounted Police is a section of the New South Wales Police Force. Currently they have a strength of 36 officers and around 38 mounts and their duties include traffic and crowd management, patrols, the Royal Canadian Mounted Police is a well-known mounted police force, although horses are no longer in use operationally. However, horses are used in the Musical Ride as well as by several provincial and municipal police detachments. The Royal Oman Police have both horse and camel mounted troopers, the United States Border Patrol had 200 horses in 2005. Most of these are employed along the U. S. -Mexico border, in Arizona, these animals are fed special processed feed pellets so that their wastes do not spread non-native plants in the national parks and wildlife areas they patrol. Philadelphias mounted police unit was disbanded in 2004, but reinstated in 2011 with four horses from the unit of Newark.
