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

Seine
–
The Seine is a 777-kilometre-long river and an important commercial waterway within the Paris Basin in the north of France. It rises at Source-Seine,30 kilometres northwest of Dijon in northeastern France in the Langres plateau, flowing through Paris and it is navigable by ocean-going vessels as far as Rouen,120 kilometres from the sea. There are 37 bridges within Paris and dozens more spanning the river outside the city, examples in Paris include the Pont Alexandre III and Pont Neuf, the latter of which dates back to 1607. Outside the city, examples include the Pont de Normandie, one of the longest cable-stayed bridges in the world, the Seine rises in the commune of Source-Seine, about 30 kilometres northwest of Dijon. The source has been owned by the city of Paris since 1864, a number of closely associated small ditches or depressions provide the source waters, with an artificial grotto laid out to highlight and contain a deemed main source. The grotto includes a statue of a nymph, on the same site are the buried remains of a Gallo-Roman temple. Small statues of the dea Sequana Seine goddess and other ex voti found at the place are now exhibited in the Dijon archeological museum. The Seine is dredged and oceangoing vessels can dock at Rouen,120 kilometres from the sea, commercial riverboats can use the river from Bar-sur-Seine,560 kilometres to its mouth. At Paris, there are 37 bridges, the river is only 24 metres above sea level 446 kilometres from its mouth, making it slow flowing and thus easily navigable. The Seine Maritime,105.7 kilometres from the English Channel at Le Havre to Rouen, is the portion of the Seine used by ocean-going craft. The tidal section of the Seine Maritime is followed by a section with four large multiple locks until the mouth of the Oise at Conflans-Sainte-Honorine. Multiple locks at Bougival / Chatou and at Suresnes lift the vessels to the level of the river in Paris, upstream from Paris seven locks ensure navigation to Saint Mammès, where the Loing mouth is situated. Through an eighth lock the river Yonne is reached at Montereau-Fault-Yonne, from the mouth of the Yonne, larger ships can continue upstream to Nogent-sur-Seine. From there on, the river is only by small craft. All navigation ends abruptly at Marcilly-sur-Seine, where the ancient Canal de la Haute-Seine used to allow vessels to continue all the way to Troyes and this canal has been abandoned for many years. The average depth of the Seine today at Paris is about 9.5 metres. Until locks were installed to raise the level in the 1800s, the river was much shallower within the city most of the time, today the depth is tightly controlled and the entire width of the river between the built-up banks on either side is normally filled with water. The average flow of the river is low, only a few cubic metres per second

Paris is the capital and most populous city of France. It has an area of 105 square kilometres and a population of 2,229,621 in 2013 within its administrative limits, the agglomeration has grown well beyond the citys administrative limits. By the 17th century, Paris was one of Europes major centres of finance, commerce, fashion, science, and the arts, and it retains that position still today. The aire urbaine de Paris, a measure of area, spans most of the Île-de-France region and has a population of 12,405,426. It is therefore the second largest metropolitan area in the European Union after London, the Metropole of Grand Paris was created in 2016, combining the commune and its nearest suburbs into a single area for economic and environmental co-operation. Grand Paris covers 814 square kilometres and has a population of 7 million persons, the Paris Region had a GDP of €624 billion in 2012, accounting for 30.0 percent of the GDP of France and ranking it as one of the wealthiest regions in Europe. The city is also a rail, highway, and air-transport hub served by two international airports, Paris-Charles de Gaulle and Paris-Orly. Opened in 1900, the subway system, the Paris Métro. It is the second busiest metro system in Europe after Moscow Metro, notably, Paris Gare du Nord is the busiest railway station in the world outside of Japan, with 262 millions passengers in 2015. In 2015, Paris received 22.2 million visitors, making it one of the top tourist destinations. The association football club Paris Saint-Germain and the rugby union club Stade Français are based in Paris, the 80, 000-seat Stade de France, built for the 1998 FIFA World Cup, is located just north of Paris in the neighbouring commune of Saint-Denis. Paris hosts the annual French Open Grand Slam tennis tournament on the red clay of Roland Garros, Paris hosted the 1900 and 1924 Summer Olympics and is bidding to host the 2024 Summer Olympics. The name Paris is derived from its inhabitants, the Celtic Parisii tribe. Thus, though written the same, the name is not related to the Paris of Greek mythology. In the 1860s, the boulevards and streets of Paris were illuminated by 56,000 gas lamps, since the late 19th century, Paris has also been known as Panam in French slang. Inhabitants are known in English as Parisians and in French as Parisiens and they are also pejoratively called Parigots. The Parisii, a sub-tribe of the Celtic Senones, inhabited the Paris area from around the middle of the 3rd century BC. One of the areas major north-south trade routes crossed the Seine on the île de la Cité, this place of land and water trade routes gradually became a town

France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans 643,801 square kilometres and had a population of almost 67 million people as of January 2017. It is a unitary republic with the capital in Paris. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse, during the Iron Age, what is now metropolitan France was inhabited by the Gauls, a Celtic people. The area was annexed in 51 BC by Rome, which held Gaul until 486, France emerged as a major European power in the Late Middle Ages, with its victory in the Hundred Years War strengthening state-building and political centralisation. During the Renaissance, French culture flourished and a colonial empire was established. The 16th century was dominated by civil wars between Catholics and Protestants. France became Europes dominant cultural, political, and military power under Louis XIV, in the 19th century Napoleon took power and established the First French Empire, whose subsequent Napoleonic Wars shaped the course of continental Europe. Following the collapse of the Empire, France endured a succession of governments culminating with the establishment of the French Third Republic in 1870. Following liberation in 1944, a Fourth Republic was established and later dissolved in the course of the Algerian War, the Fifth Republic, led by Charles de Gaulle, was formed in 1958 and remains to this day. Algeria and nearly all the colonies became independent in the 1960s with minimal controversy and typically retained close economic. France has long been a centre of art, science. It hosts Europes fourth-largest number of cultural UNESCO World Heritage Sites and receives around 83 million foreign tourists annually, France is a developed country with the worlds sixth-largest economy by nominal GDP and ninth-largest by purchasing power parity. In terms of household wealth, it ranks fourth in the world. France performs well in international rankings of education, health care, life expectancy, France remains a great power in the world, being one of the five permanent members of the United Nations Security Council with the power to veto and an official nuclear-weapon state. It is a member state of the European Union and the Eurozone. It is also a member of the Group of 7, North Atlantic Treaty Organization, Organisation for Economic Co-operation and Development, the World Trade Organization, originally applied to the whole Frankish Empire, the name France comes from the Latin Francia, or country of the Franks

Pont Neuf
–
The Pont Neuf is the oldest standing bridge across the river Seine in Paris, France. Its name, which was given to distinguish it from older bridges that were lined on both sides with houses, has remained after all of those were replaced. The bridge is composed of two spans, one of five arches joining the left bank to the Île de la Cité. Today the tip of the island is the location of the Square du Vert-Galant, as early as 1550, Henry II was asked to build a bridge here because the existing Pont Notre-Dame was overloaded, but the expense was too much at the time. In February 1578, the decision to build the bridge was made by Henry III who laid its first stone in 1578, further design changes were made during the summer of 1579. First, the number of arches was changed from eight and four to seven, second, it was decided to allow houses to be built on the bridge. This required the widening of the bridge, the remaining piers were built over the next nine years. After a long delay beginning in 1588, due to political unrest, the bridge was opened to traffic in 1604 and completed in July 1606. It was inaugurated by Henri IV in 1607, like most bridges of its time, The Pont Neuf is constructed as a series of many short arch bridges, following Roman precedents. The bridge had heavy traffic from the beginning, it was for a time the widest bridge in Paris. In 1885, one of the piers of the arm was undermined. A major restoration of the Pont Neuf was begun in 1994 and was completed in 2007, the mascarons are the stone masks,381 in number, each being different and which decorate the sides of the bridge. They represent the heads of forest and field divinities from ancient mythology, as well as satyrs, the mascarons remained in place until 1851-1854, when the bridge was completely rebuilt. At that time six of the original mascarons from the 16th century were placed in the Musée Carnavalet, eight other originals were first placed in the Musée national du Moyen Âge, and are now in the French National Museum of the Renaissance in the Château dÉcouen. Fontenelle made sixty-one masks which are found on the side of the bridge between the right bank and the Île de la Cité. After his death, Giambolognas assistant Pietro Tacca completed the statue and it was destroyed in 1792 during the French Revolution, but was rebuilt in 1818, following the restoration of the Bourbon monarchy. Bronze for the new statue was obtained with the bronze from a statue of Louis Charles Antoine Desaix, as well as from the statue of Napoleon in Place Vendôme, the new statue was cast from a mold made using a surviving cast of the original. The last Grand Master of the Knights Templar, Jacques de Molay, was burned at the stake on March 18,1314, on the Île aux Juifs, the execution was ordered by Philippe le Bel after Jacques retracted all of his previous confessions, which outraged Philip

Pont du Carrousel
–
The Pont du Carrousel is a bridge in Paris, which spans the River Seine between the Quai des Tuileries and the Quai Voltaire. The bridges architect, Antoine-Rémy Polonceau, succeeded in a design that was innovative in several aspects, the structure combined the relatively new material of cast iron with timber. Its graduated cast-iron circular supports were quickly dubbed napkin rings, at each corner of the bridge were erected classic style stone allegorical sculptures by Louis Petitot, which remain in situ. They represent Industry, Abundance, The City of Paris and The Seine, in 1906, after seven decades of use, serious restoration was required, the former wooden elements were replaced with beaten iron. Nevertheless, the bridge was too narrow for traffic. The architects Malet and Lang attempted to respect the former aspect, the new bridge of reinforced concrete still crosses the river in three arches reaching the right bank in front of the Louvre, in direct line with the Arc de Triomphe du Carrousel. The nearest Métro station is Palais Royal - Musée du Louvre, on 1 May 1995, the Moroccan immigrant Brahim Bouarram drowned after being pushed into the Seine river near the bridge by members of a Front National procession. In 2003, in the name of all the citizens of Paris, the mayor of the city, Bertrand Delanoë, honored the memory of Bouarram and all the victims of racism with a commemorative plaque on the bridge

Arch bridge
–
An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side, a viaduct may be made from a series of arches, although other more economical structures are typically used today. Possibly the oldest existing bridge is the Mycenaean Arkadiko bridge in Greece from about 1300 BC. The stone corbel arch bridge is used by the local populace. The well-preserved Hellenistic Eleutherna Bridge has a corbel arch. The 4th century BC Rhodes Footbridge rests on an early voussoir arch, a more complete survey by the Italian scholar Vittorio Galliazzo found 931 Roman bridges, mostly of stone, in as many as 26 different countries. Roman arch bridges were usually semicircular, although a number were segmental arch bridges, generally, Roman bridges featured wedge-shaped primary arch stones of the same in size and shape. The Romans built both single spans and lengthy multiple arch aqueducts, such as the Pont du Gard and Segovia Aqueduct. Their bridges featured from an early time onwards flood openings in the piers, e. g. in the Pons Fabricius in Rome, Roman engineers were the first and until the industrial revolution the only ones to construct bridges with concrete, which they called Opus caementicium. The outside was covered with brick or ashlar, as in the Alcántara bridge. The Romans also introduced segmental arch bridges into bridge construction, trajans bridge over the Danube featured open-spandrel segmental arches made of wood. This was to be the longest arch bridge for a thousand years both in terms of overall and individual span length, while the longest extant Roman bridge is the 790 m long Puente Romano at Mérida. The late Roman Karamagara Bridge in Cappadocia may represent the earliest surviving bridge featuring a pointed arch, in medieval Europe, bridge builders improved on the Roman structures by using narrower piers, thinner arch barrels and lower span-rise ratios on bridges. Gothic pointed arches were introduced, reducing lateral thrust. The 14th century in particular saw bridge building reaching new heights, the bridge at Trezzo sullAdda, destroyed in the 15th century, even featured a span length of 72 m, not matched until 1796. Constructions such as the acclaimed Florentine segmental arch bridge Ponte Vecchio combined sound engineering with aesthetical appeal, the three elegant arches of the Renaissance Ponte Santa Trinita constitute the oldest elliptic arch bridge worldwide. In China, the oldest existing bridge is the Zhaozhou Bridge of 605 AD. The Zhaozhou Bridge, with a length of 167 feet and span of 123 feet, is the worlds first wholly stone open-spandrel segmental arch bridge, Bridges with perforated spandrels can be found worldwide, such as in China

Institut de France
–
The Institut de France is a French learned society, grouping five académies, the most famous of which is the Académie française. The Institute, located in Paris, manages approximately 1,000 foundations, as well as museums and it also awards prizes and subsidies, which amounted to a total of €5,028,190.55 for 2002. Most of these prizes are awarded by the Institute on the recommendation of the académies, the Institut de France was established on 25 October 1795, by the French government. Académie française – initiated 1635, suppressed 1793, restored 1803 as a division of the institute, Académie des inscriptions et belles-lettres – initiated 1663. Académie des sciences – initiated 1666, the Royal Society of Canada, initiated 1882, was modeled after the Institut de France and the Royal Society of London

Louvre Palace
–
The Louvre Palace is a former royal palace located on the Right Bank of the Seine in Paris, between the Tuileries Gardens and the church of Saint-Germain lAuxerrois. Its present structure has evolved in stages since the 16th century, in 1793 part of the Louvre became a public museum, now the Musée du Louvre, which has expanded to occupy most of the building. The Palace is situated in the right-bank of the River Seine between Rue de Rivoli to the north and the Quai François Mitterrand to the south. To the west is the Jardin des Tuileries and, to the east, the Rue de lAmiral de Coligny, where its most architecturally famous façade, the Louvre Colonnade, the Cour Napoléon and Cour du Carrousel are separated by the street known as the Place du Carrousel. Some 51,615 sq m in the complex are devoted to public exhibition floor space. The Old Louvre occupies the site of the 12th-century fortress of King Philip Augustus and its foundations are viewable in the basement level as the Medieval Louvre department. This structure was razed in 1546 by King Francis I in favour of a royal residence which was added to by almost every subsequent French monarch. King Louis XIV, who resided at the Louvre until his departure for Versailles in 1678, completed the Cour Carrée, the Old Louvre is a quadrilateral approximately 160 m on a side consisting of 8 ailes which are articulated by 8 pavillons. With it, the last external vestiges of the medieval Louvre were demolished, the New Louvre is the name often given to the wings and pavilions extending the Palace for about 500 m westwards on the north and on the south sides of the Cour Napoléon and Cour du Carrousel. This consummation only lasted a few years, however, as the Tuileries was burned in 1871, the northern limb of the new Louvre consists of three great pavilions along the Rue de Rivoli, the Pavillon de la Bibliothèque, Pavillon de Rohan and Pavillon de Marsan. As on the side, three inside pavilions and their wings define three more subsidiary Courts, Cour du Sphinx, Cour Viconti and Cour Lefuel. The Chinese American architect I. M. Pei was selected in 1983 to design François Mitterrands Grand Louvre Project. The ground-level entrance to this complex was situated in the centre of the Cour Napoléon and is crowned by the prominent steel-and-glass pyramid, in a proposal by Kenneth Carbone, the nomenclature of the wings of the Louvre was simplified in 1987 to reflect the Grand Louvres organization. This allows the visitor to avoid becoming totally mystified at the bewildering array of named wings. The origin of the name Louvre is unclear, the French historian Henri Sauval, probably writing in the 1660s, stated that he had seen in an old Latin-Saxon glossary, Leouar is translated castle and thus took Leouar to be the origin of Louvre. According to Keith Briggs, Sauvals theory is often repeated, even in recent books, but this glossary has never seen again. Briggs suggests that H. J. Wolfs proposal in 1969 that Louvre derives instead from Latin Rubras, david Hanser, on the other hand, reports that the word may come from French louveterie, a place where dogs were trained to chase wolves. In 1190 King Philip II Augustus, who was about to leave on the Third Crusade, completed in 1202, the new fortress was situated in what is now the southwest quadrant of the Cour Carrée

First French Empire
–
The First French Empire, Note 1 was the empire of Napoleon Bonaparte of France and the dominant power in much of continental Europe at the beginning of the 19th century. Its name was a misnomer, as France already had colonies overseas and was short lived compared to the Colonial Empire, a series of wars, known collectively as the Napoleonic Wars, extended French influence over much of Western Europe and into Poland. The plot included Bonapartes brother Lucien, then serving as speaker of the Council of Five Hundred, Roger Ducos, another Director, on 9 November 1799 and the following day, troops led by Bonaparte seized control. They dispersed the legislative councils, leaving a rump legislature to name Bonaparte, Sieyès, although Sieyès expected to dominate the new regime, the Consulate, he was outmaneuvered by Bonaparte, who drafted the Constitution of the Year VIII and secured his own election as First Consul. He thus became the most powerful person in France, a power that was increased by the Constitution of the Year X, the Battle of Marengo inaugurated the political idea that was to continue its development until Napoleons Moscow campaign. Napoleon planned only to keep the Duchy of Milan for France, setting aside Austria, the Peace of Amiens, which cost him control of Egypt, was a temporary truce. He gradually extended his authority in Italy by annexing the Piedmont and by acquiring Genoa, Parma, Tuscany and Naples, then he laid siege to the Roman state and initiated the Concordat of 1801 to control the material claims of the pope. Napoleon would have ruling elites from a fusion of the new bourgeoisie, on 12 May 1802, the French Tribunat voted unanimously, with exception of Carnot, in favour of the Life Consulship for the leader of France. This action was confirmed by the Corps Législatif, a general plebiscite followed thereafter resulting in 3,653,600 votes aye and 8,272 votes nay. On 2 August 1802, Napoleon Bonaparte was proclaimed Consul for life, pro-revolutionary sentiment swept through Germany aided by the Recess of 1803, which brought Bavaria, Württemberg and Baden to Frances side. The memories of imperial Rome were for a time, after Julius Caesar and Charlemagne. The Treaty of Pressburg, signed on 26 December 1805, did little other than create a more unified Germany to threaten France. On the other hand, Napoleons creation of the Kingdom of Italy, the occupation of Ancona, to create satellite states, Napoleon installed his relatives as rulers of many European states. The Bonapartes began to marry into old European monarchies, gaining sovereignty over many nations, in addition to the vassal titles, Napoleons closest relatives were also granted the title of French Prince and formed the Imperial House of France. Met with opposition, Napoleon would not tolerate any neutral power, Prussia had been offered the territory of Hanover to stay out of the Third Coalition. With the diplomatic situation changing, Napoleon offered Great Britain the province as part of a peace proposal and this, combined with growing tensions in Germany over French hegemony, Prussia responded by forming an alliance with Russia and sending troops into Bavaria on 1 October 1806. In this War of the Fourth Coalition, Napoleon destroyed the armies of Frederick William at Jena-Auerstedt, the Eylau and the Friedland against the Russians finally ruined Frederick the Greats formerly mighty kingdom, obliging Russia and Prussia to make peace with France at Tilsit. The Treaties of Tilsit ended the war between Russia and the French Empire and began an alliance between the two empires that held power of much of the rest of Europe, the two empires secretly agreed to aid each other in disputes
