Mexico City, or the City of Mexico, is the capital of Mexico and the most populous city in North America. Mexico City is one of the most important financial centres in the Americas, it is located in the Valley of Mexico, a large valley in the high plateaus in the center of Mexico, at an altitude of 2,240 meters. The city has 16 boroughs; the 2009 population for the city proper was 8.84 million people, with a land area of 1,485 square kilometers. According to the most recent definition agreed upon by the federal and state governments, the population of Greater Mexico City is 21.3 million, which makes it the largest metropolitan area of the Western Hemisphere, the eleventh-largest agglomeration, the largest Spanish-speaking city in the world. Greater Mexico City has a GDP of $411 billion in 2011, making Greater Mexico City one of the most productive urban areas in the world; the city was responsible for generating 15.8% of Mexico's GDP, the metropolitan area accounted for about 22% of total national GDP.
If it were an independent country, in 2013, Mexico City would be the fifth-largest economy in Latin America, five times as large as Costa Rica and about the same size as Peru. Mexico’s capital is both the oldest capital city in the Americas and one of two founded by Native Americans, the other being Quito, Ecuador; the city was built on an island of Lake Texcoco by the Aztecs in 1325 as Tenochtitlan, completely destroyed in the 1521 siege of Tenochtitlan and subsequently redesigned and rebuilt in accordance with the Spanish urban standards. In 1524, the municipality of Mexico City was established, known as México Tenochtitlán, as of 1585, it was known as Ciudad de México. Mexico City was the political and financial center of a major part of the Spanish colonial empire. After independence from Spain was achieved, the federal district was created in 1824. After years of demanding greater political autonomy, residents were given the right to elect both a Head of Government and the representatives of the unicameral Legislative Assembly by election in 1997.
Since, the left-wing Party of the Democratic Revolution has controlled both of them. The city has several progressive policies, such as abortion on request, a limited form of euthanasia, no-fault divorce, same-sex marriage. On January 29, 2016, it ceased to be the Federal District, is now known as Ciudad de México, with a greater degree of autonomy. A clause in the Constitution of Mexico, prevents it from becoming a state, as it is the seat of power in the country, unless the capital of the country were relocated elsewhere; the city of Mexico-Tenochtitlan was founded by the Mexica people in 1325. The old Mexica city, now referred to as Tenochtitlan was built on an island in the center of the inland lake system of the Valley of Mexico, which it shared with a smaller city-state called Tlatelolco. According to legend, the Mexicas' principal god, indicated the site where they were to build their home by presenting a golden eagle perched on a prickly pear devouring a rattlesnake. Between 1325 and 1521, Tenochtitlan grew in size and strength dominating the other city-states around Lake Texcoco and in the Valley of Mexico.
When the Spaniards arrived, the Aztec Empire had reached much of Mesoamerica, touching both the Gulf of Mexico and the Pacific Ocean. After landing in Veracruz, Spanish explorer Hernán Cortés advanced upon Tenochtitlan with the aid of many of the other native peoples, arriving there on November 8, 1519. Cortés and his men marched along the causeway leading into the city from Iztapalapa, the city's ruler, Moctezuma II, greeted the Spaniards. Cortés put Moctezuma under house arrest. Tensions increased until, on the night of June 30, 1520 – during a struggle known as "La Noche Triste" – the Aztecs rose up against the Spanish intrusion and managed to capture or drive out the Europeans and their Tlaxcalan allies. Cortés regrouped at Tlaxcala; the Aztecs thought the Spaniards were permanently gone, they elected a new king, Cuitláhuac, but he soon died. Cortés began a siege of Tenochtitlan in May 1521. For three months, the city suffered from the lack of food and water as well as the spread of smallpox brought by the Europeans.
Cortés and his allies landed their forces in the south of the island and fought their way through the city. Cuauhtémoc surrendered in August 1521; the Spaniards razed Tenochtitlan during the final siege of the conquest. Cortés first settled in Coyoacán, but decided to rebuild the Aztec site to erase all traces of the old order, he did not establish a territory under his own personal rule, but remained loyal to the Spanish crown. The first Spanish viceroy arrived in Mexico City fourteen years later. By that time, the city had again become a city-state, having power that extended far beyond its borders. Although the Spanish preserved Tenochtitlan's basic layout, they built Catholic churches over the old Aztec temples and claimed the imperial palaces for themselves. Tenochtitlan was renamed "Mexico"; the city had been the capital of the Aztec empire and in the colonial era, Mexico City became the capital of New Spain. The viceroy of Mexico or vice-king lived in the viceregal palace on Zócalo; the Mexico City Metropolitan Cathedral, the seat of the Archbishopric of New Spain, was const
A mobile phone, cell phone, cellphone, or hand phone, sometimes shortened to mobile, cell or just phone, is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network. Modern mobile telephone services use a cellular network architecture, therefore, mobile telephones are called cellular telephones or cell phones, in North America. In addition to telephony, 2000s-era mobile phones support a variety of other services, such as text messaging, MMS, Internet access, short-range wireless communications, business applications, video games, digital photography. Mobile phones offering only those capabilities are known as feature phones; the first handheld mobile phone was demonstrated by John F. Mitchell and Martin Cooper of Motorola in 1973, using a handset weighing c. 2 kilograms.
In 1979, Nippon Telegraph and Telephone launched the world's first cellular network in Japan. In 1983, the DynaTAC 8000x was the first commercially available handheld mobile phone. From 1983 to 2014, worldwide mobile phone subscriptions grew to over seven billion—enough to provide one for every person on Earth. In first quarter of 2016, the top smartphone developers worldwide were Samsung and Huawei, smartphone sales represented 78 percent of total mobile phone sales. For feature phones as of 2016, the largest were Samsung and Alcatel. A handheld mobile radio telephone service was envisioned in the early stages of radio engineering. In 1917, Finnish inventor Eric Tigerstedt filed a patent for a "pocket-size folding telephone with a thin carbon microphone". Early predecessors of cellular phones included analog radio communications from trains; the race to create portable telephone devices began after World War II, with developments taking place in many countries. The advances in mobile telephony have been traced in successive "generations", starting with the early zeroth-generation services, such as Bell System's Mobile Telephone Service and its successor, the Improved Mobile Telephone Service.
These 0G systems were not cellular, supported few simultaneous calls, were expensive. The first handheld cellular mobile phone was demonstrated by John F. Mitchell and Martin Cooper of Motorola in 1973, using a handset weighing 2 kilograms; the first commercial automated cellular network analog was launched in Japan by Nippon Telegraph and Telephone in 1979. This was followed in 1981 by the simultaneous launch of the Nordic Mobile Telephone system in Denmark, Finland and Sweden. Several other countries followed in the early to mid-1980s; these first-generation systems could support far more simultaneous calls but still used analog cellular technology. In 1983, the DynaTAC 8000x was the first commercially available handheld mobile phone. In 1991, the second-generation digital cellular technology was launched in Finland by Radiolinja on the GSM standard; this sparked competition in the sector as the new operators challenged the incumbent 1G network operators. Ten years in 2001, the third generation was launched in Japan by NTT DoCoMo on the WCDMA standard.
This was followed by 3.5G, 3G+ or turbo 3G enhancements based on the high-speed packet access family, allowing UMTS networks to have higher data transfer speeds and capacity. By 2009, it had become clear that, at some point, 3G networks would be overwhelmed by the growth of bandwidth-intensive applications, such as streaming media; the industry began looking to data-optimized fourth-generation technologies, with the promise of speed improvements up to ten-fold over existing 3G technologies. The first two commercially available technologies billed as 4G were the WiMAX standard, offered in North America by Sprint, the LTE standard, first offered in Scandinavia by TeliaSonera. 5G is a technology and term used in research papers and projects to denote the next major phase in mobile telecommunication standards beyond the 4G/IMT-Advanced standards. The term 5G is not used in any specification or official document yet made public by telecommunication companies or standardization bodies such as 3GPP, WiMAX Forum or ITU-R.
New standards beyond 4G are being developed by standardization bodies, but they are at this time seen as under the 4G umbrella, not for a new mobile generation. Smartphones have a number of distinguishing features; the International Telecommunication Union measures those with Internet connection, which it calls Active Mobile-Broadband subscriptions. In the developed world, smartphones have now overtaken the usage of earlier mobile systems. However, in the developing world, they account for around 50% of mobile telephony. Feature phone is a term used as a retronym to describe mobile phones which are limited in capabilities in contrast to a modern smartphone. Feature phones provide voice calling and text messaging functionality, in addition to basic multimedia and Internet capabilities, other services offered by the user's wireless service provider. A feature phone has additional functions over and above a basic mobile phone, only capable of voice calling and text messaging. Feature phones and basic mobile phones tend to use a proprietary, custom-designed software and user interface.
By contrast, smartphones use a mobile operating system that shares common traits across devices. There are Orthodox Jewish religious re
New York City
The City of New York called either New York City or New York, is the most populous city in the United States. With an estimated 2017 population of 8,622,698 distributed over a land area of about 302.6 square miles, New York is the most densely populated major city in the United States. Located at the southern tip of the state of New York, the city is the center of the New York metropolitan area, the largest metropolitan area in the world by urban landmass and one of the world's most populous megacities, with an estimated 20,320,876 people in its 2017 Metropolitan Statistical Area and 23,876,155 residents in its Combined Statistical Area. A global power city, New York City has been described as the cultural and media capital of the world, exerts a significant impact upon commerce, research, education, tourism, art and sports; the city's fast pace has inspired the term New York minute. Home to the headquarters of the United Nations, New York is an important center for international diplomacy.
Situated on one of the world's largest natural harbors, New York City consists of five boroughs, each of, a separate county of the State of New York. The five boroughs – Brooklyn, Manhattan, The Bronx, Staten Island – were consolidated into a single city in 1898; the city and its metropolitan area constitute the premier gateway for legal immigration to the United States. As many as 800 languages are spoken in New York, making it the most linguistically diverse city in the world. New York City is home to more than 3.2 million residents born outside the United States, the largest foreign-born population of any city in the world. In 2017, the New York metropolitan area produced a gross metropolitan product of US$1.73 trillion. If greater New York City were a sovereign state, it would have the 12th highest GDP in the world. New York is home to the highest number of billionaires of any city in the world. New York City traces its origins to a trading post founded by colonists from the Dutch Republic in 1624 on Lower Manhattan.
The city and its surroundings came under English control in 1664 and were renamed New York after King Charles II of England granted the lands to his brother, the Duke of York. New York served as the capital of the United States from 1785 until 1790, it has been the country's largest city since 1790. The Statue of Liberty greeted millions of immigrants as they came to the U. S. by ship in the late 19th and early 20th centuries and is an international symbol of the U. S. and its ideals of liberty and peace. In the 21st century, New York has emerged as a global node of creativity and entrepreneurship, social tolerance, environmental sustainability, as a symbol of freedom and cultural diversity. Many districts and landmarks in New York City are well known, with the city having three of the world's ten most visited tourist attractions in 2013 and receiving a record 62.8 million tourists in 2017. Several sources have ranked New York the most photographed city in the world. Times Square, iconic as the world's "heart" and its "Crossroads", is the brightly illuminated hub of the Broadway Theater District, one of the world's busiest pedestrian intersections, a major center of the world's entertainment industry.
The names of many of the city's landmarks and parks are known around the world. Manhattan's real estate market is among the most expensive in the world. New York is home to the largest ethnic Chinese population outside of Asia, with multiple signature Chinatowns developing across the city. Providing continuous 24/7 service, the New York City Subway is the largest single-operator rapid transit system worldwide, with 472 rail stations. Over 120 colleges and universities are located in New York City, including Columbia University, New York University, Rockefeller University, which have been ranked among the top universities in the world. Anchored by Wall Street in the Financial District of Lower Manhattan, New York has been called both the most economically powerful city and the leading financial center of the world, the city is home to the world's two largest stock exchanges by total market capitalization, the New York Stock Exchange and NASDAQ. In 1664, the city was named in honor of the Duke of York.
James's older brother, King Charles II, had appointed the Duke proprietor of the former territory of New Netherland, including the city of New Amsterdam, which England had seized from the Dutch. During the Wisconsinan glaciation, 75,000 to 11,000 years ago, the New York City region was situated at the edge of a large ice sheet over 1,000 feet in depth; the erosive forward movement of the ice contributed to the separation of what is now Long Island and Staten Island. That action left bedrock at a shallow depth, providing a solid foundation for most of Manhattan's skyscrapers. In the precolonial era, the area of present-day New York City was inhabited by Algonquian Native Americans, including the Lenape, whose homeland, known as Lenapehoking, included Staten Island; the first documented visit into New York Harbor by a European was in 1524 by Giovanni da Verrazzano, a Florentine explorer in the service of the French crown. He named it Nouvelle Angoulême. A Spanish expedition led by captain Estêvão Gomes, a Portuguese sailing for Emperor Charles V, arrived in New York Harbor in January 1525 and charted the mouth of the Hudson River, which he named Río de San Antonio.

Wi-Fi is technology for radio wireless local area networking of devices based on the IEEE 802.11 standards. Wi‑Fi is a trademark of the Wi-Fi Alliance, which restricts the use of the term Wi-Fi Certified to products that complete after many years of testing the 802.11 committee interoperability certification testing. Devices that can use Wi-Fi technologies include, among others and laptops, video game consoles and tablets, smart TVs, digital audio players, digital cameras and drones. Wi-Fi compatible devices can connect to the Internet via a wireless access point; such an access point has a range of about 20 meters indoors and a greater range outdoors. Hotspot coverage can be as small as a single room with walls that block radio waves, or as large as many square kilometres achieved by using multiple overlapping access points. Different versions of Wi-Fi exist, with radio bands and speeds. Wi-Fi most uses the 2.4 gigahertz UHF and 5 gigahertz SHF ISM radio bands. Each channel can be time-shared by multiple networks.
These wavelengths work best for line-of-sight. Many common materials absorb or reflect them, which further restricts range, but can tend to help minimise interference between different networks in crowded environments. At close range, some versions of Wi-Fi, running on suitable hardware, can achieve speeds of over 1 Gbit/s. Anyone within range with a wireless network interface controller can attempt to access a network. Wi-Fi Protected Access is a family of technologies created to protect information moving across Wi-Fi networks and includes solutions for personal and enterprise networks. Security features of WPA have included stronger protections and new security practices as the security landscape has changed over time. In 1971, ALOHAnet connected the Hawaiian Islands with a UHF wireless packet network. ALOHAnet and the ALOHA protocol were early forerunners to Ethernet, the IEEE 802.11 protocols, respectively. A 1985 ruling by the U. S. Federal Communications Commission released the ISM band for unlicensed use.
These frequency bands are the same ones used by equipment such as microwave ovens and are subject to interference. In 1991, NCR Corporation with AT&T Corporation invented the precursor to 802.11, intended for use in cashier systems, under the name WaveLAN. The Australian radio-astronomer Dr John O'Sullivan with his colleagues Terence Percival, Graham Daniels, Diet Ostry, John Deane developed a key patent used in Wi-Fi as a by-product of a Commonwealth Scientific and Industrial Research Organisation research project, "a failed experiment to detect exploding mini black holes the size of an atomic particle". Dr O'Sullivan and his colleagues are credited with inventing Wi-Fi. In 1992 and 1996, CSIRO obtained patents for a method used in Wi-Fi to "unsmear" the signal; the first version of the 802.11 protocol was released in 1997, provided up to 2 Mbit/s link speeds. This was updated in 1999 with 802.11b to permit 11 Mbit/s link speeds, this proved to be popular. In 1999, the Wi-Fi Alliance formed as a trade association to hold the Wi-Fi trademark under which most products are sold.
Wi-Fi uses a large number of patents held by many different organizations. In April 2009, 14 technology companies agreed to pay CSIRO $1 billion for infringements on CSIRO patents; this led to Australia labeling Wi-Fi as an Australian invention, though this has been the subject of some controversy. CSIRO won a further $220 million settlement for Wi-Fi patent-infringements in 2012 with global firms in the United States required to pay the CSIRO licensing rights estimated to be worth an additional $1 billion in royalties. In 2016, the wireless local area network Test Bed was chosen as Australia's contribution to the exhibition A History of the World in 100 Objects held in the National Museum of Australia; the name Wi-Fi, commercially used at least as early as August 1999, was coined by the brand-consulting firm Interbrand. The Wi-Fi Alliance had hired Interbrand to create a name, "a little catchier than'IEEE 802.11b Direct Sequence'." Phil Belanger, a founding member of the Wi-Fi Alliance who presided over the selection of the name "Wi-Fi", has stated that Interbrand invented Wi-Fi as a pun on the word hi-fi, a term for high-quality audio technology.
Interbrand created the Wi-Fi logo. The yin-yang Wi-Fi logo indicates the certification of a product for interoperability; the Wi-Fi Alliance used the advertising slogan "The Standard for Wireless Fidelity" for a short time after the brand name was created. While inspired by the term hi-fi, the name was never "Wireless Fidelity"; the Wi-Fi Alliance was called the "Wireless Fidelity Alliance Inc" in some publications. Non-Wi-Fi technologies intended for fixed points, such as Motorola Canopy, are described as fixed wireless. Alternative wireless technologies include mobile phone standards, such as 2G, 3G, 4G, LTE; the name is sometimes written as WiFi, Wifi, or wifi, but these are not approved by the Wi-Fi Alliance. IEEE is a separate, but related organization and their website has stated "WiFi is a short name for Wireless Fidelity". To connect to a Wi-Fi LAN, a computer has to be equipped with a wireless network interface controller; the combination of computer and interface controllers is called a station.
A service set is the set of all the devices associated with a particular Wi-Fi network. The service set can be local, extended or mesh; each service set has an associated identifier, the 32-byte Service Set Identifier, which identifies the partic
Sydney is the state capital of New South Wales and the most populous city in Australia and Oceania. Located on Australia's east coast, the metropolis surrounds Port Jackson and extends about 70 km on its periphery towards the Blue Mountains to the west, Hawkesbury to the north, the Royal National Park to the south and Macarthur to the south-west. Sydney is made up of 40 local government areas and 15 contiguous regions. Residents of the city are known as "Sydneysiders"; as of June 2017, Sydney's estimated metropolitan population was 5,230,330 and is home to 65% of the state's population. Indigenous Australians have inhabited the Sydney area for at least 30,000 years, thousands of engravings remain throughout the region, making it one of the richest in Australia in terms of Aboriginal archaeological sites. During his first Pacific voyage in 1770, Lieutenant James Cook and his crew became the first Europeans to chart the eastern coast of Australia, making landfall at Botany Bay and inspiring British interest in the area.
In 1788, the First Fleet of convicts, led by Arthur Phillip, founded Sydney as a British penal colony, the first European settlement in Australia. Phillip named the city Sydney in recognition of 1st Viscount Sydney. Penal transportation to New South Wales ended soon after Sydney was incorporated as a city in 1842. A gold rush occurred in the colony in 1851, over the next century, Sydney transformed from a colonial outpost into a major global cultural and economic centre. After World War II, it experienced mass migration and became one of the most multicultural cities in the world. At the time of the 2011 census, more than 250 different languages were spoken in Sydney. In the 2016 Census, about 35.8% of residents spoke a language other than English at home. Furthermore, 45.4% of the population reported having been born overseas, making Sydney the 3rd largest foreign born population of any city in the world after London and New York City, respectively. Despite being one of the most expensive cities in the world, the 2018 Mercer Quality of Living Survey ranks Sydney tenth in the world in terms of quality of living, making it one of the most livable cities.
It is classified as an Alpha+ World City by Globalization and World Cities Research Network, indicating its influence in the region and throughout the world. Ranked eleventh in the world for economic opportunity, Sydney has an advanced market economy with strengths in finance and tourism. There is a significant concentration of foreign banks and multinational corporations in Sydney and the city is promoted as Australia's financial capital and one of Asia Pacific's leading financial hubs. Established in 1850, the University of Sydney is Australia's first university and is regarded as one of the world's leading universities. Sydney is home to the oldest library in Australia, State Library of New South Wales, opened in 1826. Sydney has hosted major international sporting events such as the 2000 Summer Olympics; the city is among the top fifteen most-visited cities in the world, with millions of tourists coming each year to see the city's landmarks. Boasting over 1,000,000 ha of nature reserves and parks, its notable natural features include Sydney Harbour, the Royal National Park, Royal Botanic Garden and Hyde Park, the oldest parkland in the country.
Built attractions such as the Sydney Harbour Bridge and the World Heritage-listed Sydney Opera House are well known to international visitors. The main passenger airport serving the metropolitan area is Kingsford-Smith Airport, one of the world's oldest continually operating airports. Established in 1906, Central station, the largest and busiest railway station in the state, is the main hub of the city's rail network; the first people to inhabit the area now known as Sydney were indigenous Australians having migrated from northern Australia and before that from southeast Asia. Radiocarbon dating suggests human activity first started to occur in the Sydney area from around 30,735 years ago. However, numerous Aboriginal stone tools were found in Western Sydney's gravel sediments that were dated from 45,000 to 50,000 years BP, which would indicate that there was human settlement in Sydney earlier than thought; the first meeting between the native people and the British occurred on 29 April 1770 when Lieutenant James Cook landed at Botany Bay on the Kurnell Peninsula and encountered the Gweagal clan.
He noted in his journal that they were somewhat hostile towards the foreign visitors. Cook was not commissioned to start a settlement, he spent a short time collecting food and conducting scientific observations before continuing further north along the east coast of Australia and claiming the new land he had discovered for Britain. Prior to the arrival of the British there were 4,000 to 8,000 native people in Sydney from as many as 29 different clans; the earliest British settlers called the natives Eora people. "Eora" is the term the indigenous population used to explain their origins upon first contact with the British. Its literal meaning is "from this place". Sydney Cove from Port Jackson to Petersham was inhabited by the Cadigal clan; the principal language groups were Darug and Dharawal. The earliest Europeans to visit the area noted that the indigenous people were conducting activities such as camping and fishing, using trees for bark and food, collecting shells, cooking fish. Britain—before that, England—and Ireland had for a long time been sending their convicts across the Atlantic to the American colonies.
That trade was ended with the Declaration of Independence by the United States in 1776. Britain decided in 1786 to found a new penal outpost in the territory discovered by Cook some 16 years ear
Slovakia the Slovak Republic, is a landlocked country in Central Europe. It is bordered by Poland to the north, Ukraine to the east, Hungary to the south, Austria to the west, the Czech Republic to the northwest. Slovakia's territory spans about 49,000 square kilometres and is mountainous; the population is over 5.4 million and consists of Slovaks. The capital and largest city is Bratislava, the second largest city is Košice; the official language is Slovak. The Slavs arrived in the territory of present-day Slovakia in the 6th centuries. In the 7th century, they played a significant role in the creation of Samo's Empire and in the 9th century established the Principality of Nitra, conquered by the Principality of Moravia to establish Great Moravia. In the 10th century, after the dissolution of Great Moravia, the territory was integrated into the Principality of Hungary, which would become the Kingdom of Hungary in 1000. In 1241 and 1242, much of the territory was destroyed by the Mongols during their invasion of Central and Eastern Europe.
The area was recovered thanks to Béla IV of Hungary who settled Germans which became an important ethnic group in the area in what are today parts of central and eastern Slovakia. After World War I and the dissolution of the Austro-Hungarian Empire, the Czechoslovak National Council established Czechoslovakia. A separate Slovak Republic existed during World War II as a totalitarian, clero-fascist one-party client state of Nazi Germany. At the end of World War II, Czechoslovakia was re-established as an independent country. A coup in 1948 ushered in a totalitarian one-party state under the Communist regime during whose rule the country existed as a satellite of the Soviet Union. Attempts for liberalization of communism in Czechoslovakia culminated in the Prague Spring, crushed by the Warsaw Pact invasion of Czechoslovakia in August 1968. In 1989, the Velvet Revolution ended the Communist rule in Czechoslovakia peacefully. Slovakia became an independent state on 1 January 1993 after the peaceful dissolution of Czechoslovakia, sometimes known as the Velvet Divorce.
Slovakia is a developed country, with a high-income advanced economy and a high Human Development Index, a high standard of living and performs favourably in measurements of civil liberties, press freedom, internet freedom, democratic governance and peacefulness. The country maintains a combination of market economy with a comprehensive social security system. Citizens of Slovakia are provided with universal health care, free education and one of the longest paid parental leave in the OECD; the country joined the European Union on 1 May 2004 and joined the Eurozone on 1 January 2009. Slovakia is a member of the Schengen Area, NATO, the United Nations, the OECD, the WTO, CERN, the OSCE, the Council of Europe and the Visegrád Group. Although regional income inequality is high, 90% of citizens own their homes. In 2018, Slovak citizens had visa-free or visa-on-arrival access to 179 countries and territories, ranking the Slovak passport 10th in the world; as part of Eurozone, Slovak legal tender is the world's 2nd-most-traded currency.
Slovakia is the world's largest per-capita car producer with a total of 1,040,000 cars manufactured in the country in 2016 alone and the 7th largest car producer in the European Union. The car industry represents 43% of Slovakia's industrial output, a quarter of its exports; the first written mention of name Slovakia is in 1586. It derives from the Czech word Slováky; the native name Slovensko derives from an older name of Slovaks Sloven what may indicate its origin before the 15th century. The original meaning was geographic, since Slovakia was a part of the multiethnic Kingdom of Hungary and did not form a separate administrative unit in this period. Radiocarbon dating puts the oldest surviving archaeological artefacts from Slovakia – found near Nové Mesto nad Váhom – at 270,000 BCE, in the Early Paleolithic era; these ancient tools, made by the Clactonian technique, bear witness to the ancient habitation of Slovakia. Other stone tools from the Middle Paleolithic era come from the Prévôt cave in Bojnice and from other nearby sites.
The most important discovery from that era is a Neanderthal cranium, discovered near Gánovce, a village in northern Slovakia. Archaeologists have found prehistoric human skeletons in the region, as well as numerous objects and vestiges of the Gravettian culture, principally in the river valleys of Nitra, Ipeľ, Váh and as far as the city of Žilina, near the foot of the Vihorlat and Tribeč mountains, as well as in the Myjava Mountains; the most well-known finds include the oldest female statue made of mammoth-bone, the famous Venus of Moravany. The statue was found in the 1940s in Moravany nad Váhom near Piešťany. Numerous necklaces made of shells from Cypraca thermophile gastropods of the Tertiary period have come from the sites of Zákovská, Podkovice and Radošina; these findings provide the most ancient evidence of commercial exchanges carried out between the Mediterranean and central Europe. The Bronze Age in the geographical territory of modern-day Slovakia went through three stages of development, stretching from 2000 to 800 BCE.
Major cultural and political development can be attributed to the significant growth in production of copper in central Slovakia and northwe
Singapore the Republic of Singapore, is an island city-state in Southeast Asia. It lies one degree north of the equator, at the southern tip of the Malay Peninsula, with Indonesia's Riau Islands to the south and Peninsular Malaysia to the north. Singapore's territory consists of one main island along with 62 other islets. Since independence, extensive land reclamation has increased its total size by 23%; the country is known for its transition from a developing to a developed one in a single generation under the leadership of its founder Lee Kuan Yew. In 1819, Sir Stamford Raffles founded colonial Singapore as a trading post of the British East India Company. After the company's collapse in 1858, the islands were ceded to the British Raj as a crown colony. During the Second World War, Singapore was occupied by Japan, it gained independence from the British Empire in 1963 by joining Malaysia along with other former British territories, but separated two years over ideological differences, becoming a sovereign nation in 1965.
After early years of turbulence and despite lacking natural resources and a hinterland, the nation developed as an Asian Tiger economy, based on external trade and its workforce. Singapore is a global hub for education, finance, human capital, logistics, technology, tourism and transport; the city ranks in numerous international rankings, has been recognised as the most "technology-ready" nation, top International-meetings city, city with "best investment potential", world's smartest city, world's safest country, second-most competitive country, third least-corrupt country, third-largest foreign exchange market, third-largest financial centre, third-largest oil refining and trading centre, fifth-most innovative country, the second-busiest container port. The Economist has ranked Singapore as the most expensive city to live in, since 2013, it is identified as a tax haven. Singapore is the only country in Asia with an AAA sovereign rating from all major rating agencies, one of 11 worldwide.
