Archaeology, or archeology, is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, biofacts or ecofacts and cultural landscapes. Archaeology can be considered a branch of the humanities. In North America archaeology is a sub-field of anthropology, while in Europe it is viewed as either a discipline in its own right or a sub-field of other disciplines. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, the study of fossil remains, it is important for learning about prehistoric societies, for whom there may be no written records to study. Prehistory includes over 99% of the human past, from the Paleolithic until the advent of literacy in societies across the world. Archaeology has various goals, which range from understanding culture history to reconstructing past lifeways to documenting and explaining changes in human societies through time.
The discipline involves surveying and analysis of data collected to learn more about the past. In broad scope, archaeology relies on cross-disciplinary research, it draws upon anthropology, art history, ethnology, geology, literary history, semiology, textual criticism, information sciences, statistics, paleography, paleontology and paleobotany. Archaeology developed out of antiquarianism in Europe during the 19th century, has since become a discipline practiced across the world. Archaeology has been used by nation-states to create particular visions of the past. Since its early development, various specific sub-disciplines of archaeology have developed, including maritime archaeology, feminist archaeology and archaeoastronomy, numerous different scientific techniques have been developed to aid archaeological investigation. Nonetheless, archaeologists face many problems, such as dealing with pseudoarchaeology, the looting of artifacts, a lack of public interest, opposition to the excavation of human remains.
The science of archaeology grew out of the older multi-disciplinary study known as antiquarianism. Antiquarians studied history with particular attention to ancient artifacts and manuscripts, as well as historical sites. Antiquarianism focused on the empirical evidence that existed for the understanding of the past, encapsulated in the motto of the 18th-century antiquary, Sir Richard Colt Hoare, "We speak from facts not theory". Tentative steps towards the systematization of archaeology as a science took place during the Enlightenment era in Europe in the 17th and 18th centuries. In Europe, philosophical interest in the remains of Greco-Roman civilization and the rediscovery of classical culture began in the late Middle Age. Flavio Biondo, an Italian Renaissance humanist historian, created a systematic guide to the ruins and topography of ancient Rome in the early 15th century, for which he has been called an early founder of archaeology. Antiquarians of the 16th century, including John Leland and William Camden, conducted surveys of the English countryside, drawing and interpreting the monuments that they encountered.
One of the first sites to undergo archaeological excavation was Stonehenge and other megalithic monuments in England. John Aubrey was a pioneer archaeologist who recorded numerous megalithic and other field monuments in southern England, he was ahead of his time in the analysis of his findings. He attempted to chart the chronological stylistic evolution of handwriting, medieval architecture and shield-shapes. Excavations were carried out by the Spanish military engineer Roque Joaquín de Alcubierre in the ancient towns of Pompeii and Herculaneum, both of, covered by ash during the Eruption of Mount Vesuvius in AD 79; these excavations began in 1748 in Pompeii, while in Herculaneum they began in 1738. The discovery of entire towns, complete with utensils and human shapes, as well the unearthing of frescos, had a big impact throughout Europe. However, prior to the development of modern techniques, excavations tended to be haphazard; the father of archaeological excavation was William Cunnington. He undertook excavations in Wiltshire from around 1798.
Cunnington made meticulous recordings of Neolithic and Bronze Age barrows, the terms he used to categorize and describe them are still used by archaeologists today. One of the major achievements of 19th-century archaeology was the development of stratigraphy; the idea of overlapping strata tracing back to successive periods was borrowed from the new geological and paleontological work of scholars like William Smith, James Hutton and Charles Lyell. The application of stratigraphy to archaeology first took place with the excavations of prehistorical and Bronze Age sites. In the third and fourth decades of the 19th-century, archaeologists like Jacques Boucher de Perthes and Christian Jürgensen Thomsen began to put the artifacts they had found in chronological order. A major figure in the development of archaeology into a rigorous science was the army officer and ethnologist, Augustus Pitt Rivers, who began excavations on his land in England in the 1880s, his approach was methodical by the standards of the time, he is regarded as the first scientific archaeologist.
He arranged his artifacts by type or "typologically, within types by date or "chronologically"
A defensive wall is a fortification used to protect a city, town or other settlement from potential aggressors. In ancient to modern times, they were used to enclose settlements; these are referred to as city walls or town walls, although there were walls, such as the Great Wall of China, Walls of Benin, Hadrian's Wall, Anastasian Wall, the Cyclopean Wall Rajgir and the metaphorical Atlantic Wall, which extended far beyond the borders of a city and were used to enclose regions or mark territorial boundaries. In mountainous terrain, defensive walls such as letzis were used in combination with castles to seal valleys from potential attack. Beyond their defensive utility, many walls had important symbolic functions – representing the status and independence of the communities they embraced. Existing ancient walls are always masonry structures, although brick and timber-built variants are known. Depending on the topography of the area surrounding the city or the settlement the wall is intended to protect, elements of the terrain such as rivers or coastlines may be incorporated in order to make the wall more effective.
Walls may only be crossed by entering the appropriate city gate and are supplemented with towers. The practice of building these massive walls, though having its origins in prehistory, was refined during the rise of city-states, energetic wall-building continued into the medieval period and beyond in certain parts of Europe. Simpler defensive walls of earth or stone, thrown up around hillforts, early castles and the like, tend to be referred to as ramparts or banks. From early history to modern times, walls have been a near necessity for every city. Uruk in ancient Sumer is one of the world's oldest known walled cities. Before that, the proto-city of Jericho in the West Bank in Palestine had a wall surrounding it as early as the 8th millennium BC; the Assyrians deployed large labour forces to build new palaces and defensive walls. Some settlements in the Indus Valley Civilization were fortified. By about 3500 BC, hundreds of small farming villages dotted the Indus floodplain. Many of these settlements had planned streets.
The stone and mud brick houses of Kot Diji were clustered behind massive stone flood dykes and defensive walls, for neighboring communities quarreled about the control of prime agricultural land. Mundigak in present-day south-east Afghanistan has defensive walls and square bastions of sun dried bricks. Babylon was one of the most famous cities of the ancient world as a result of the building program of Nebuchadnezzar, who expanded the walls and built the Ishtar Gate. Exceptions were few, but neither ancient Sparta nor ancient Rome had walls for a long time, choosing to rely on their militaries for defense instead; these fortifications were simple constructions of wood and earth, which were replaced by mixed constructions of stones piled on top of each other without mortar. In Central Europe, the Celts built large fortified settlements which the Romans called oppida, whose walls seem influenced by those built in the Mediterranean; the fortifications were continuously improved. In ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae.
In classical era Greece, the city of Athens built a long set of parallel stone walls called the Long Walls that reached their guarded seaport at Piraeus. Large rammed earth walls were built in ancient China since the Shang Dynasty, as the capital at ancient Ao had enormous walls built in this fashion. Although stone walls were built in China during the Warring States, mass conversion to stone architecture did not begin in earnest until the Tang Dynasty. Sections of the Great Wall had been built prior to the Qin Dynasty and subsequently connected and fortified during the Qin dynasty, although its present form was an engineering feat and remodeling of the Ming Dynasty; the large walls of Pingyao serve as one example. The walls of the Forbidden City in Beijing were established in the early 15th century by the Yongle Emperor; the Romans fortified their cities with mortar-bound stone walls. Among these are the extant Aurelian Walls of Rome and the Theodosian Walls of Constantinople, together with partial remains elsewhere.
These are city gates, like the Porta Nigra in Trier or Newport Arch in Lincoln. Apart from these, the early Middle Ages saw the creation of some towns built around castles; these cities were only protected by simple stone walls and more by a combination of both walls and ditches. From the 12th century AD hundreds of settlements of all sizes were founded all across Europe, which often obtained the right of fortification soon afterwards; the founding of urban centers was an important means of territorial expansion and many cities in central and eastern Europe, were founded for this purpose during the period of Eastern settlement. These cities are easy to recognise due to their regular layout and large market spaces; the fortifications of these settlements were continuously improved to reflect the current level of military development. During the Renaissance era, the Venetians raised great walls around cities threatened by the Ottoman Empire. Examples include the walled cities of Nicosia and Famagusta in Cyprus and the fortifications of Candia and Chania in Crete, which still stand.
At its simplest, a defensive wall consists of its gates. For the most part, the top of the walls were accessible, with the outside of the walls ha
The Daily Telegraph
The Daily Telegraph referred to as The Telegraph, is a national British daily broadsheet newspaper published in London by Telegraph Media Group and distributed across the United Kingdom and internationally. It was founded by Arthur B. Sleigh in 1855 as Daily Telegraph & Courier; the Telegraph is regarded as a national "newspaper of record" and it maintains an international reputation for quality, having been described by the BBC as "one of the world's great titles". The paper's motto, "Was, is, will be", appears in the editorial pages and has featured in every edition of the newspaper since 19 April 1858; the paper had a circulation of 363,183 in December 2018, having declined following industry trends from 1.4 million in 1980. Its sister paper, The Sunday Telegraph, which started in 1961, had a circulation of 281,025 as of December 2018; the Daily Telegraph has the largest circulation for a broadsheet newspaper in the UK and the sixth largest circulation of any UK newspaper as of 2016. The two sister newspapers are run separately, with different editorial staff, but there is cross-usage of stories.
Articles published in either may be published on the Telegraph Media Group's www.telegraph.co.uk website, under the title of The Telegraph. Editorially, the paper is considered conservative; the Telegraph has been the first newspaper to report on a number of notable news scoops, including the 2009 MP expenses scandal, which led to a number of high-profile political resignations and for which it was named 2009 British Newspaper of the Year, its 2016 undercover investigation on the England football manager Sam Allardyce. However, including the paper's former chief political commentator Peter Oborne, accuse it of being unduly influenced by advertisers HSBC; the Daily Telegraph and Courier was founded by Colonel Arthur B. Sleigh in June 1855 to air a personal grievance against the future commander-in-chief of the British Army, Prince George, Duke of Cambridge. Joseph Moses Levy, the owner of The Sunday Times, agreed to print the newspaper, the first edition was published on 29 June 1855; the paper was four pages long.
The first edition stressed the quality and independence of its articles and journalists: We shall be guided by a high tone of independent action. However, the paper was not a success, Sleigh was unable to pay Levy the printing bill. Levy took over the newspaper, his aim being to produce a cheaper newspaper than his main competitors in London, the Daily News and The Morning Post, to expand the size of the overall market. Levy appointed his son, Edward Levy-Lawson, Lord Burnham, Thornton Leigh Hunt to edit the newspaper. Lord Burnham relaunched the paper as The Daily Telegraph, with the slogan "the largest and cheapest newspaper in the world". Hunt laid out the newspaper's principles in a memorandum sent to Levy: "We should report all striking events in science, so told that the intelligent public can understand what has happened and can see its bearing on our daily life and our future; the same principle should apply to all other events—to fashion, to new inventions, to new methods of conducting business".
In 1876, Jules Verne published his novel Michael Strogoff, whose plot takes place during a fictional uprising and war in Siberia. Verne included among the book's characters a war correspondent of The Daily Telegraph, named Harry Blount—who is depicted as an exceptionally dedicated and brave journalist, taking great personal risks to follow the ongoing war and bring accurate news of it to The Telegraph's readership, ahead of competing papers. In 1908, Kaiser Wilhelm II of Germany gave a controversial interview to The Daily Telegraph that damaged Anglo-German relations and added to international tensions in the build-up to World War I. In 1928 the son of Baron Burnham, Harry Lawson Webster Levy-Lawson, 2nd Baron Burnham, sold the paper to William Berry, 1st Viscount Camrose, in partnership with his brother Gomer Berry, 1st Viscount Kemsley and Edward Iliffe, 1st Baron Iliffe. In 1937, the newspaper absorbed The Morning Post, which traditionally espoused a conservative position and sold predominantly amongst the retired officer class.
William Ewart Berry, 1st Viscount Camrose, bought The Morning Post with the intention of publishing it alongside The Daily Telegraph, but poor sales of the former led him to merge the two. For some years the paper was retitled The Daily Telegraph and Morning Post before it reverted to just The Daily Telegraph. In the late 1930s Victor Gordon Lennox, The Telegraph's diplomatic editor, published an anti-appeasement private newspaper The Whitehall Letter that received much of its information from leaks from Sir Robert Vansittart, the Permanent Under-Secretary of the Foreign Office, Rex Leeper, the Foreign Office's Press Secretary; as a result, Gordon Lennox was monitored by MI5. In 1939, The Telegraph published Clare Hollingworth's scoop. In November 1940, with Fleet Street subjected to daily bombing raids by the Luftwaffe, The Telegraph started printing in Manchester at Kemsley House, run by Camrose's brother Kemsley. Manchester quite printed the entire run of The Telegraph when its Fleet Street offices were under threat.
The name Kemsley House was changed to Thomson House in 1959. In 1986 printing of Northern editions of the Daily and Sunday Telegraph moved to Trafford Park and in 2008 to Newsprinters at Knowsley, Liverpool. During the Second World War, The Daily Telegraph covertly helped in the recruitment of code-breakers for Bletchley Park; the ability to solve The Telegraph's crossword in under 12 minutes was considered to be a recruitment test. The newspaper was asked to organise a crossword competition, after wh
An earthquake is the shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to toss people around and destroy whole cities; the seismicity, or seismic activity, of an area is the frequency and size of earthquakes experienced over a period of time. The word tremor is used for non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground; when the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes can trigger landslides, volcanic activity. In its most general sense, the word earthquake is used to describe any seismic event—whether natural or caused by humans—that generates seismic waves. Earthquakes are caused by rupture of geological faults, but by other events such as volcanic activity, mine blasts, nuclear tests.
An earthquake's point of initial rupture is called its hypocenter. The epicenter is the point at ground level directly above the hypocenter. Tectonic earthquakes occur anywhere in the earth where there is sufficient stored elastic strain energy to drive fracture propagation along a fault plane; the sides of a fault move past each other smoothly and aseismically only if there are no irregularities or asperities along the fault surface that increase the frictional resistance. Most fault surfaces do have such asperities and this leads to a form of stick-slip behavior. Once the fault has locked, continued relative motion between the plates leads to increasing stress and therefore, stored strain energy in the volume around the fault surface; this continues until the stress has risen sufficiently to break through the asperity allowing sliding over the locked portion of the fault, releasing the stored energy. This energy is released as a combination of radiated elastic strain seismic waves, frictional heating of the fault surface, cracking of the rock, thus causing an earthquake.
This process of gradual build-up of strain and stress punctuated by occasional sudden earthquake failure is referred to as the elastic-rebound theory. It is estimated that only 10 percent or less of an earthquake's total energy is radiated as seismic energy. Most of the earthquake's energy is used to power the earthquake fracture growth or is converted into heat generated by friction. Therefore, earthquakes lower the Earth's available elastic potential energy and raise its temperature, though these changes are negligible compared to the conductive and convective flow of heat out from the Earth's deep interior. There are three main types of fault, all of which may cause an interplate earthquake: normal and strike-slip. Normal and reverse faulting are examples of dip-slip, where the displacement along the fault is in the direction of dip and movement on them involves a vertical component. Normal faults occur in areas where the crust is being extended such as a divergent boundary. Reverse faults occur in areas.
Strike-slip faults are steep structures where the two sides of the fault slip horizontally past each other. Many earthquakes are caused by movement on faults that have components of both dip-slip and strike-slip. Reverse faults those along convergent plate boundaries are associated with the most powerful earthquakes, megathrust earthquakes, including all of those of magnitude 8 or more. Strike-slip faults continental transforms, can produce major earthquakes up to about magnitude 8. Earthquakes associated with normal faults are less than magnitude 7. For every unit increase in magnitude, there is a thirtyfold increase in the energy released. For instance, an earthquake of magnitude 6.0 releases 30 times more energy than a 5.0 magnitude earthquake and a 7.0 magnitude earthquake releases 900 times more energy than a 5.0 magnitude of earthquake. An 8.6 magnitude earthquake releases the same amount of energy as 10,000 atomic bombs like those used in World War II. This is so because the energy released in an earthquake, thus its magnitude, is proportional to the area of the fault that ruptures and the stress drop.
Therefore, the longer the length and the wider the width of the faulted area, the larger the resulting magnitude. The topmost, brittle part of the Earth's crust, the cool slabs of the tectonic plates that are descending down into the hot mantle, are the only parts of our planet which can store elastic energy and release it in fault ruptures. Rocks hotter than about 300 °C flow in response to stress; the maximum observed lengths of ruptures and mapped faults are 1,000 km. Examples are the earthquakes in Chile, 1960; the longest earthquake ruptures on strike-slip faults, like the San Andreas Fault, the North Anatolian Fault in Turkey and the Denali Fault in Alaska, are about half to one third as long as the lengths along subducting plate margins, those along normal faults are shorter. The most important parameter controlling the maximum earthquake magnitude on a fault is however not the maximum available length, but the available width because the latter varies by a factor of 20. Along converging plate margins, the dip angle of the rupture plane is shallow about 10 de
Austria the Republic of Austria, is a country in Central Europe comprising 9 federated states. Its capital, largest city and one of nine states is Vienna. Austria has an area of 83,879 km2, a population of nearly 9 million people and a nominal GDP of $477 billion, it is bordered by the Czech Republic and Germany to the north and Slovakia to the east and Italy to the south, Switzerland and Liechtenstein to the west. The terrain is mountainous, lying within the Alps; the majority of the population speaks local Bavarian dialects as their native language, German in its standard form is the country's official language. Other regional languages are Hungarian, Burgenland Croatian, Slovene. Austria played a central role in European History from the late 18th to the early 20th century, it emerged as a margraviate around 976 and developed into a duchy and archduchy. In the 16th century, Austria started serving as the heart of the Habsburg Monarchy and the junior branch of the House of Habsburg – one of the most influential royal houses in history.
As archduchy, it was a major component and administrative centre of the Holy Roman Empire. Following the Holy Roman Empire's dissolution, Austria founded its own empire in the 19th century, which became a great power and the leading force of the German Confederation. Subsequent to the Austro-Prussian War and the establishment of a union with Hungary, the Austro-Hungarian Empire was created. Austria was involved in both world wars. Austria is a parliamentary representative democracy with a President as head of state and a Chancellor as head of government. Major urban areas of Austria include Graz, Linz and Innsbruck. Austria is ranked as one of the richest countries in the world by per capita GDP terms; the country has developed a high standard of living and in 2018 was ranked 20th in the world for its Human Development Index. The republic declared its perpetual neutrality in foreign political affairs in 1955. Austria has been a member of the United Nations since 1955 and joined the European Union in 1995.
It is a founding member of the OECD and Interpol. Austria signed the Schengen Agreement in 1995, adopted the euro currency in 1999; the German name for Austria, Österreich, derives from the Old High German Ostarrîchi, which meant "eastern realm" and which first appeared in the "Ostarrîchi document" of 996. This word is a translation of Medieval Latin Marchia orientalis into a local dialect. Another theory says that this name comes from the local name of the mountain whose original Slovenian name is "Ostravica" - because it is steep on both sides. Austria was a prefecture of Bavaria created in 976; the word "Austria" was first recorded in the 12th century. At the time, the Danube basin of Austria was the easternmost extent of Bavaria; the Central European land, now Austria was settled in pre-Roman times by various Celtic tribes. The Celtic kingdom of Noricum was claimed by the Roman Empire and made a province. Present-day Petronell-Carnuntum in eastern Austria was an important army camp turned capital city in what became known as the Upper Pannonia province.
Carnuntum was home for 50,000 people for nearly 400 years. After the fall of the Roman Empire, the area was invaded by Bavarians and Avars. Charlemagne, King of the Franks, conquered the area in AD 788, encouraged colonization, introduced Christianity; as part of Eastern Francia, the core areas that now encompass Austria were bequeathed to the house of Babenberg. The area was known as the marchia Orientalis and was given to Leopold of Babenberg in 976; the first record showing the name Austria is from 996, where it is written as Ostarrîchi, referring to the territory of the Babenberg March. In 1156, the Privilegium Minus elevated Austria to the status of a duchy. In 1192, the Babenbergs acquired the Duchy of Styria. With the death of Frederick II in 1246, the line of the Babenbergs was extinguished; as a result, Ottokar II of Bohemia assumed control of the duchies of Austria and Carinthia. His reign came to an end with his defeat at Dürnkrut at the hands of Rudolph I of Germany in 1278. Thereafter, until World War I, Austria's history was that of its ruling dynasty, the Habsburgs.
In the 14th and 15th centuries, the Habsburgs began to accumulate other provinces in the vicinity of the Duchy of Austria. In 1438, Duke Albert V of Austria was chosen as the successor to his father-in-law, Emperor Sigismund. Although Albert himself only reigned for a year, henceforth every emperor of the Holy Roman Empire was a Habsburg, with only one exception; the Habsburgs began to accumulate territory far from the hereditary lands. In 1477, Archduke Maximilian, only son of Emperor Frederick III, married the heiress Maria of Burgundy, thus acquiring most of the Netherlands for the family. In 1496, his son Philip the Fair married Joanna the Mad, the heiress of Castile and Aragon, thus acquiring Spain and its Italian and New World appendages for the Habsburgs. In 1526, following the Battle of Mohács, Bohemia and the part of Hungary not occupied by the Ottomans came under Austrian rule. Ottoman expansion into Hungary led to frequent conflicts between the two empires evident in the Long War of 1593 to 1606.
The Turks made incursions into Styria nearly 20 times, of which some are c
A city is a large human settlement. Cities have extensive systems for housing, sanitation, land use, communication, their density facilitates interaction between people, government organizations and businesses, sometimes benefiting different parties in the process. City-dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization half of the world population now lives in cities, which has had profound consequences for global sustainability. Present-day cities form the core of larger metropolitan areas and urban areas—creating numerous commuters traveling towards city centers for employment and edification. However, in a world of intensifying globalization, all cities are in different degree connected globally beyond these regions; the most populated city proper is Chongqing while the most populous metropolitan areas are the Greater Tokyo Area, the Shanghai area, Jabodetabek. The cities of Faiyum and Varanasi are among those laying claim to longest continual inhabitation.
A city is distinguished from other human settlements by its great size, but by its functions and its special symbolic status, which may be conferred by a central authority. The term can refer either to the physical streets and buildings of the city or to the collection of people who dwell there, can be used in a general sense to mean urban rather than rural territory. A variety of definitions, invoking population, population density, number of dwellings, economic function, infrastructure, are used in national censuses to classify populations as urban. Common population definitions for a city range between 1,500 and 50,000 people, with most U. S. states using a minimum between 5,000 inhabitants. However, some jurisdictions set no such minimums. In the United Kingdom, city status is awarded by the government and remains permanently, resulting in some small cities, such as Wells and St Davids. According to the "functional definition" a city is not distinguished by size alone, but by the role it plays within a larger political context.
Cities serve as administrative, commercial and cultural hubs for their larger surrounding areas. Examples of settlements called city which may not meet any of the traditional criteria to be named such include Broad Top City and City Dulas, Anglesey, a hamlet; the presence of a literate elite is sometimes included in the definition. A typical city has professional administrators and some form of taxation to support the government workers; the governments may be based on heredity, military power, work projects such as canal building, food distribution, land ownership, commerce, finance, or a combination of these. Societies that live in cities are called civilizations; the word city and the related civilization come, via Old French, from the Latin root civitas meaning citizenship or community member and coming to correspond with urbs, meaning city in a more physical sense. The Roman civitas was linked with the Greek "polis"—another common root appearing in English words such as metropolis. Urban geography deals both with their internal structure.
Town siting has varied through history according to natural, technological and military contexts. Access to water has long been a major factor in city placement and growth, despite exceptions enabled by the advent of rail transport in the nineteenth century, through the present most of the world's urban population lives near the coast or on a river. Urban areas as a rule cannot produce their own food and therefore must develop some relationship with a hinterland which sustains them. Only in special cases such as mining towns which play a vital role in long-distance trade, are cities disconnected from the countryside which feeds them. Thus, centrality within a productive region influences siting, as economic forces would in theory favor the creation of market places in optimal mutually reachable locations; the vast majority of cities have a central area containing buildings with special economic and religious significance. Archaeologists refer to this area by the Greek term temenos; these spaces reflect and amplify the city's centrality and importance to its wider sphere of influence.
Today cities have downtown, sometimes coincident with a central business district. Cities have public spaces where anyone can go; these include owned spaces open to the public as well as forms of public land such as public domain and the commons. Western philosophy since the time of the Greek agora has considered physical public space as the substrate of the symbolic public sphere. Public art adorns public spaces. Parks and other natural sites within cities provide residents with relief from the hardness and regularity of typical built environments. Urban structure follows one or more basic patterns: geomorphic, concentric and curvilinear. Physical environment constrains the form in which a city is built. If located on a mountainside, urban structure may rely on winding roads, it may be adapted to its means of subsistence. And it may be set up for optimal defense given the surrounding landscape. Beyond these "geomorphi
The Balkans known as the Balkan Peninsula, is a geographic area in southeastern Europe with various definitions and meanings, including geopolitical and historical. The region takes its name from the Balkan Mountains that stretch throughout the whole of Bulgaria from the Serbian-Bulgarian border to the Black Sea coast; the Balkan Peninsula is bordered by the Adriatic Sea on the northwest, the Ionian Sea on the southwest, the Aegean Sea in the south and southeast, the Black Sea on the east and northeast. The northern border of the peninsula is variously defined; the highest point of the Balkans is 2,925 metres, in the Rila mountain range. The concept of the Balkan peninsula was created by the German geographer August Zeune in 1808, who mistakenly considered the Balkan Mountains the dominant mountain system of Southeast Europe spanning from the Adriatic Sea to the Black Sea; the term of Balkan Peninsula was a synonym for European Turkey in the 19th century, the former provinces of the Ottoman Empire in Southeast Europe.
It had a geopolitical rather than a geographical definition, further promoted during the creation of the Kingdom of Yugoslavia in the early 20th century. The definition of the Balkan peninsula's natural borders do not coincide with the technical definition of a peninsula and hence modern geographers reject the idea of a Balkan peninsula, while scholars discuss the Balkans as a region; the term has acquired a stigmatized and pejorative meaning related to the process of Balkanization, hence the rather used alternative term for the region is Southeast Europe. The word Balkan comes from Ottoman Turkish balkan'chain of wooded mountains'; the origin of the Turkic word is obscure. From classical antiquity through the Middle Ages, the Balkan Mountains were called by the local Thracian name Haemus. According to Greek mythology, the Thracian king Haemus was turned into a mountain by Zeus as a punishment and the mountain has remained with his name. A reverse name scheme has been suggested. D. Dechev considers that Haemus is derived from a Thracian word *saimon,'mountain ridge'.
A third possibility is that "Haemus" derives from the Greek word "haema" meaning'blood'. The myth relates to a fight between the monster/titan Typhon. Zeus injured Typhon with a thunder bolt and Typhon's blood fell on the mountains, from which they got their name; the earliest mention of the name appears in an early 14th-century Arab map, in which the Haemus mountains are referred to as Balkan. The first attested time the name "Balkan" was used in the West for the mountain range in Bulgaria was in a letter sent in 1490 to Pope Innocent VIII by Buonaccorsi Callimaco, an Italian humanist and diplomat; the Ottomans first mention it in a document dated from 1565. There has been no other documented usage of the word to refer to the region before that, although other Turkic tribes had settled in or were passing through the Peninsula. There is a claim about an earlier Bulgar Turkic origin of the word popular in Bulgaria, however it is only an unscholarly assertion; the word was used by the Ottomans in Rumelia in its general meaning of mountain, as in Kod̲j̲a-Balkan, Čatal-Balkan, Ungurus-Balkani̊, but it was applied to the Haemus mountain.
The name is still preserved in Central Asia with the Balkan Daglary and the Balkan Province of Turkmenistan. English traveler John Morritt introduced this term into the English literature at the end of the 18th-century, other authors started applying the name to the wider area between the Adriatic and the Black Sea; the concept of the "Balkans" was created by the German geographer August Zeune in 1808, who mistakenly considered it as the dominant central mountain system of Southeast Europe spanning from the Adriatic Sea to the Black Sea. During the 1820s, "Balkan became the preferred although not yet exclusive term alongside Haemus among British travelers... Among Russian travelers not so burdened by classical toponymy, Balkan was the preferred term"; the term was not used in geographical literature until the mid-19th century because then scientists like Carl Ritter warned that only the part South of the Balkan Mountains can be considered as a peninsula and considered it to be renamed as "Greek peninsula".
Other prominent geographers who didn't agree with Zeune were Hermann Wagner, Theobald Fischer, Marion Newbigin, Albrecht Penck, while Austrian diplomat Johann Georg von Hahn in 1869 for the same territory used the term Südostereuropäische Halbinsel. Another reason it was not accepted as the definition of European Turkey had a similar land extent. However, after the Congress of Berlin there was a political need for a new term and the Balkans was revitalized, but in the maps the northern border was in Serbia and Montenegro without Greece, while Yugoslavian maps included Croatia and Bosnia; the term Balkan Peninsula was a synonym for European Turkey, the political borders of former Ottoman Empire provinces. The usage of the term changed in the end of the 19th and beginning of the 20th century when was embraced by Serbian geographers, most prominently by Jovan Cvijić, it was done with political reasoning as affirmation for Serbian nationalism on the whole territory of the South Slavs, included anthropological and ethnological studies of the South Slavs through which were claimed various nationalistic and racistic theories.
Through such policies and Yugoslavian maps the term was elevated to the modern status of
