Agriculture is the science and art of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities; the history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture into the twenty-first. Modern agronomy, plant breeding, agrochemicals such as pesticides and fertilizers, technological developments have increased yields, while causing widespread ecological and environmental damage. Selective breeding and modern practices in animal husbandry have increased the output of meat, but have raised concerns about animal welfare and environmental damage.
Environmental issues include contributions to global warming, depletion of aquifers, antibiotic resistance, growth hormones in industrial meat production. Genetically modified organisms are used, although some are banned in certain countries; the major agricultural products can be broadly grouped into foods, fibers and raw materials. Food classes include cereals, fruits, meat, milk and eggs. Over one-third of the world's workers are employed in agriculture, second only to the service sector, although the number of agricultural workers in developed countries has decreased over the centuries; the word agriculture is a late Middle English adaptation of Latin agricultūra, from ager, "field", which in its turn came from Greek αγρός, cultūra, "cultivation" or "growing". While agriculture refers to human activities, certain species of ant and ambrosia beetle cultivate crops. Agriculture is defined with varying scopes, in its broadest sense using natural resources to "produce commodities which maintain life, including food, forest products, horticultural crops, their related services".
Thus defined, it includes arable farming, animal husbandry and forestry, but horticulture and forestry are in practice excluded. The development of agriculture enabled the human population to grow many times larger than could be sustained by hunting and gathering. Agriculture began independently in different parts of the globe, included a diverse range of taxa, in at least 11 separate centres of origin. Wild grains were eaten from at least 105,000 years ago. From around 11,500 years ago, the eight Neolithic founder crops and einkorn wheat, hulled barley, lentils, bitter vetch, chick peas and flax were cultivated in the Levant. Rice was domesticated in China between 11,500 and 6,200 BC with the earliest known cultivation from 5,700 BC, followed by mung and azuki beans. Sheep were domesticated in Mesopotamia between 11,000 years ago. Cattle were domesticated from the wild aurochs in the areas of modern Turkey and Pakistan some 10,500 years ago. Pig production emerged in Eurasia, including Europe, East Asia and Southwest Asia, where wild boar were first domesticated about 10,500 years ago.
In the Andes of South America, the potato was domesticated between 10,000 and 7,000 years ago, along with beans, llamas and guinea pigs. Sugarcane and some root vegetables were domesticated in New Guinea around 9,000 years ago. Sorghum was domesticated in the Sahel region of Africa by 7,000 years ago. Cotton was domesticated in Peru by 5,600 years ago, was independently domesticated in Eurasia. In Mesoamerica, wild teosinte was bred into maize by 6,000 years ago. Scholars have offered multiple hypotheses to explain the historical origins of agriculture. Studies of the transition from hunter-gatherer to agricultural societies indicate an initial period of intensification and increasing sedentism. Wild stands, harvested started to be planted, came to be domesticated. In Eurasia, the Sumerians started to live in villages from about 8,000 BC, relying on the Tigris and Euphrates rivers and a canal system for irrigation. Ploughs appear in pictographs around 3,000 BC. Farmers grew wheat, vegetables such as lentils and onions, fruits including dates and figs.
Ancient Egyptian agriculture relied on its seasonal flooding. Farming started in the predynastic period at the end of the Paleolithic, after 10,000 BC. Staple food crops were grains such as wheat and barley, alongside industrial crops such as flax and papyrus. In India, wheat and jujube were domesticated by 9,000 BC, soon followed by sheep and goats. Cattle and goats were domesticated in Mehrgarh culture by 8,000–6,000 BC. Cotton was cultivated by the 5th-4th millennium BC. Archeological evidence indicates an animal-drawn plough from 2,500 BC in the Indus Valley Civilisation. In China, from the 5th century BC there was a nationwide granary system and widespread silk farming. Water-powered grain mills were in use followed by irrigation. By the late 2nd century, heavy ploughs had been developed with iron mouldboards; these spread westwards across Eurasia. Asian rice was domesticated 8,200–13,500 years ago – depending on the molecular clock estimate, used – on the Pearl River in southern China with a single genetic origin from the wild rice Oryza rufipogon
Agricultural machinery is machinery used in farming or other agriculture. There are many types of such equipment, from hand tools and power tools to tractors and the countless kinds of farm implements that they tow or operate. Diverse arrays of equipment are used in both nonorganic farming. Since the advent of mechanised agriculture, agricultural machinery is an indispensable part of how the world is fed. With the coming of the Industrial Revolution and the development of more complicated machines, farming methods took a great leap forward. Instead of harvesting grain by hand with a sharp blade, wheeled machines cut a continuous swath. Instead of threshing the grain by beating it with sticks, threshing machines separated the seeds from the heads and stalks; the first tractors appeared in the late 19th century. Power for agricultural machinery was supplied by ox or other domesticated animals. With the invention of steam power came the portable engine, the traction engine, a multipurpose, mobile energy source, the ground-crawling cousin to the steam locomotive.
Agricultural steam engines took over the heavy pulling work of oxen, were equipped with a pulley that could power stationary machines via the use of a long belt. The steam-powered machines were low-powered by today's standards but, because of their size and their low gear ratios, they could provide a large drawbar pull, their slow speed led farmers to comment that tractors had two speeds: "slow, damn slow." The internal combustion engine. These engines contributed to the development of the self-propelled, combined harvester and thresher, or combine harvester. Instead of cutting the grain stalks and transporting them to a stationary threshing machine, these combines cut and separated the grain while moving continuously through the field. Combines might have taken the harvesting job away from tractors, but tractors still do the majority of work on a modern farm, they are used to push/pull implements—machines that till the ground, plant seed, perform other tasks. Tillage implements prepare the soil for planting by loosening the soil and killing weeds or competing plants.
The best-known is the plow, the ancient implement, upgraded in 1838 by John Deere. Plows are now used less in the U. S. than with offset disks used instead to turn over the soil, chisels used to gain the depth needed to retain moisture. The most common type of seeder is called a planter, spaces seeds out in long rows, which are two to three feet apart; some crops are planted by drills, which put out much more seed in rows less than a foot apart, blanketing the field with crops. Transplanters automate the task of transplanting seedlings to the field. With the widespread use of plastic mulch, plastic mulch layers and seeders lay down long rows of plastic, plant through them automatically. After planting, other implements can be used to cultivate weeds from between rows, or to spread fertilizer and pesticides. Hay balers can be used to package grass or alfalfa into a storable form for the winter months. Modern irrigation relies on machinery. Engines and other specialized gear provide water and in high volumes to large areas of land.
Similar types of equipment can be used to deliver pesticides. Besides the tractor, other vehicles have been adapted for use in farming, including trucks and helicopters, such as for transporting crops and making equipment mobile, to aerial spraying and livestock herd management; the basic technology of agricultural machines has changed little in the last century. Though modern harvesters and planters may do a better job or be tweaked from their predecessors, the US$250,000 combine of today still cuts and separates grain in the same way it has always been done. However, technology is changing the way that humans operate the machines, as computer monitoring systems, GPS locators, self-steer programs allow the most advanced tractors and implements to be more precise and less wasteful in the use of fuel, seed, or fertilizer. In the foreseeable future, there may be mass production of driverless tractors, which use GPS maps and electronic sensors. Many farmers are upset by their inability to fix the new types of high-tech farm equipment.
This is due to companies using intellectual property law to prevent farmers from having the legal right to fix their equipment. In October 2015 an exemption was added to the DMCA to allow inspection and modification of the software in cars and other vehicles including agricultural machinery.

Marketing is the study and management of exchange relationships. Marketing is the business process of satisfying customers. With its focus on the customer, marketing is one of the premier components of business management. Marketing is defined by the American Marketing Association as "the activity, set of institutions, processes for creating, communicating and exchanging offerings that have value for customers, clients and society at large." The term developed from the original meaning which referred to going to market with goods for sale. From a sales process engineering perspective, marketing is "a set of processes that are interconnected and interdependent with other functions" of a business aimed at achieving customer interest and satisfaction. Philip Kotler defines marketing as Satisfying wants through an exchange process; the Chartered Institute of Marketing defines marketing as "the management process responsible for identifying and satisfying customer requirements profitably." A similar concept is the value-based marketing which states the role of marketing to contribute to increasing shareholder value.
In this context, marketing can be defined as "the management process that seeks to maximise returns to shareholders by developing relationships with valued customers and creating a competitive advantage."Marketing practice tended to be seen as a creative industry in the past, which included advertising and selling. However, because the academic study of marketing makes extensive use of social sciences, sociology, economics and neuroscience, the profession is now recognized as a science, allowing numerous universities to offer Master-of-Science programs; the process of marketing is that of bringing a product to market, which includes these steps: broad market research. Many parts of the marketing process involve use of the creative arts. The'marketing concept' proposes that in order to satisfy the organizational objectives, an organization should anticipate the needs and wants of potential consumers and satisfy them more than its competitors; this concept originated from Adam Smith's book The Wealth of Nations, but would not become used until nearly 200 years later.
Marketing and Marketing Concepts are directly related. Given the centrality of customer needs and wants in marketing, a rich understanding of these concepts is essential: Needs: Something necessary for people to live a healthy and safe life; when needs remain unfulfilled, there is a clear adverse outcome: death. Needs can be objective and physical, such as the need for food and shelter. Wants: Something, desired, wished for or aspired to. Wants are not essential for basic survival and are shaped by culture or peer-groups. Demands: When needs and wants are backed by the ability to pay, they have the potential to become economic demands. Marketing research, conducted for the purpose of new product development or product improvement, is concerned with identifying the consumer's unmet needs. Customer needs are central to market segmentation, concerned with dividing markets into distinct groups of buyers on the basis of "distinct needs, characteristics, or behaviors who might require separate products or marketing mixes."
Needs-based segmentation "places the customers' desires at the forefront of how a company designs and markets products or services." Although needs-based segmentation is difficult to do in practice, it has been proved to be one of the most effective ways to segment a market. In addition, a great deal of advertising and promotion is designed to show how a given product's benefits meet the customer's needs, wants or expectations in a unique way. A marketing orientation has been defined as a "philosophy of business management." Or "a corporate state of mind" or as an "organisation culture" Although scholars continue to debate the precise nature of specific orientations that inform marketing practice, the most cited orientations are as follows: A firm employing a product orientation is concerned with the quality of its own product. A product orientation is based on the assumption that, all things being equal, consumers will purchase products of a superior quality; the approach is most effective when the firm has deep insights into customers and their needs and desires derived from research and intuition and understands consumers' quality expectations and price they are willing to pay.
For example, Sony Walkman and Apple iPod were innovative product designs that addressed consumers' unmet needs. Although the product orientation has been supplanted by the marketing orientation, firms practicing a product orientation can still be found in haute couture and in arts marketing. A firm using a sales orientation focuses on the selling/promotion of the firm's existing products, rather than determining new or unmet consumer needs or desires; this entails selling existing products, using promotion and direct sales techniques to attain the highest sales possible. The sales orientation "is practiced with unsought goods." One study found that industrial companies are more to hold a sales orientation than consumer goods companies. The approach may suit scenarios in wh
Manufacturing is the production of products for use or sale using labour and machines, tools and biological processing, or formulation. The term may refer to a range of human activity, from handicraft to high tech, but is most applied to industrial design, in which raw materials are transformed into finished goods on a large scale; such finished goods may be sold to other manufacturers for the production of other, more complex products, such as aircraft, household appliances, sports equipment or automobiles, or sold to wholesalers, who in turn sell them to retailers, who sell them to end users and consumers. Manufacturing engineering or manufacturing process are the steps through which raw materials are transformed into a final product; the manufacturing process begins with the product design, materials specification from which the product is made. These materials are modified through manufacturing processes to become the required part. Modern manufacturing includes all intermediate processes required in the production and integration of a product's components.
Some industries, such as semiconductor and steel manufacturers use the term fabrication instead. The manufacturing sector is connected with engineering and industrial design. Examples of major manufacturers in North America include General Motors Corporation, General Electric, Procter & Gamble, General Dynamics, Boeing and Precision Castparts. Examples in Europe include Volkswagen Siemens, FCA and Michelin. Examples in Asia include Toyota, Panasonic, LG, Samsung and Tata Motors. In its earliest form, manufacturing was carried out by a single skilled artisan with assistants. Training was by apprenticeship. In much of the pre-industrial world, the guild system protected the privileges and trade secrets of urban artisans. Before the Industrial Revolution, most manufacturing occurred in rural areas, where household-based manufacturing served as a supplemental subsistence strategy to agriculture. Entrepreneurs organized a number of manufacturing households into a single enterprise through the putting-out system.
Toll manufacturing is an arrangement whereby a first firm with specialized equipment processes raw materials or semi-finished goods for a second firm. Manufacturing Engineering Agile manufacturing American system of manufacturing British factory system of manufacturing Craft or guild system Fabrication Flexible manufacturing Just-in-time manufacturing Lean manufacturing Mass customization – 3D printing, design-your-own web sites for sneakers, fast fashion Mass production Ownership Packaging and labeling Prefabrication Putting-out system Rapid manufacturing Reconfigurable manufacturing system Soviet collectivism in manufacturing History of numerical control Emerging technologies have provided some new growth in advanced manufacturing employment opportunities in the Manufacturing Belt in the United States. Manufacturing provides important material support for national infrastructure and for national defense. On the other hand, most manufacturing may involve significant environmental costs; the clean-up costs of hazardous waste, for example, may outweigh the benefits of a product that creates it.
Hazardous materials may expose workers to health risks. These costs are now well known and there is effort to address them by improving efficiency, reducing waste, using industrial symbiosis, eliminating harmful chemicals; the negative costs of manufacturing can be addressed legally. Developed countries regulate manufacturing activity with environmental laws. Across the globe, manufacturers can be subject to regulations and pollution taxes to offset the environmental costs of manufacturing activities. Labor unions and craft guilds have played a historic role in the negotiation of worker rights and wages. Environment laws and labor protections that are available in developed nations may not be available in the third world. Tort law and product liability impose additional costs on manufacturing; these are significant dynamics in the ongoing process, occurring over the last few decades, of manufacture-based industries relocating operations to "developing-world" economies where the costs of production are lower than in "developed-world" economies.
Manufacturing has unique health and safety challenges and has been recognized by the National Institute for Occupational Safety and Health as a priority industry sector in the National Occupational Research Agenda to identify and provide intervention strategies regarding occupational health and safety issues. Surveys and analyses of trends and issues in manufacturing and investment around the world focus on such things as: The nature and sources of the considerable variations that occur cross-nationally in levels of manufacturing and wider industrial-economic growth. In addition to general overviews, researchers have examined the features and factors affecting particular key aspects of manufacturing development, they have compared production and investment in a range of Western and non-Western countries and presented case studies of growth and performance in important individual industries and market-economic sectors. On June 26, 2009, Jeff Immelt, the CEO of General Electric, called for the United States to increase its manufacturing base employment to 20% of the workforce, commenting that the U.
S. has outsourced too much in some areas and can no longer rely on the financial sector and consumer spending to drive demand. Further, while U. S. manufacturing performs well compared to the rest of the U. S. economy, research shows that it performs poorly compared to manufacturing in other high-wage countries. A total of 3.2 million – one in six U. S. manuf
A road roller is a compactor type engineering vehicle used to compact soil, concrete, or asphalt in the construction of roads and foundations. Similar rollers are used at landfills or in agriculture. Road rollers are referred to as steamrollers, regardless of their method of propulsion; the first road rollers were horse-drawn, were just borrowed farm implements. Since the effectiveness of a roller depends to a large extent on its weight, self-powered vehicles replaced horse-drawn rollers from the mid-19th century; the first such vehicles were steam rollers. Single-cylinder steam rollers were used for base compaction and run with high engine revs with low gearing to promote bounce and vibration from the crankshaft through to the rolls in much the same way as a vibrating roller; the double cylinder or compound steam rollers became popular from around 1910 onwards and were used for the rolling of hot-laid surfaces due to their smoother running engines, but both cylinder types are capable of rolling the finished surface.
Steam rollers were dedicated to a task by their gearing as the slower engines were for base compaction whereas the higher geared models were referred to as'chip chasers' which followed behind the hot tar and chipping laying machines. Some road companies in the United States used steamrollers through the 1950s, in the UK, some remained in commercial service until the early 1970s; as internal combustion engine technology improved during the 20th century, kerosene-, gasoline-, diesel-powered rollers replaced their steam-powered counterparts. The first internal-combustion powered road rollers were similar to the steam rollers they replaced, they used similar mechanisms to transmit power from the engine to the wheels large, exposed spur gears. Some users did not like them in their infancy, as the engines of the era were difficult to start the kerosene-powered ones. All road rollers in commercial use now use diesel power. Road rollers feature in films, both as objects of violence and horror and of hilarity, for example Jojo's Bizarre Adventure and A Fish Called Wanda.
Road rollers use the weight of the vehicle to compress the surface being rolled or use mechanical advantage. Initial compaction of the substrate on a road project is done using a padfoot drum roller, which achieves higher compaction density due to the pads having less surface area. On large freeways a four-wheel compactor with padfoot drum and a blade, such as a Caterpillar 815/825 series machine, would be used due to its high weight and the powerful pushing force to spread bulk material. On regional roads a smaller single padfoot drum machine may be used; the next machine is a single smooth drum compactor that compacts the high spots down until the soil is smooth, this is done in combination with a motor grader to get a level surface. Sometimes at this stage a pneumatic tyre roller would be used; these rollers feature two rows of pneumatic tyres that overlap, the flexibility of the tyres provides a kneading action that seals the surface and with some vertical movement of the wheels, enables the roller to operate on uneven ground.
Once the soil base is flat the pad drum compactor is no longer used on the road surface. The next course would be compacted using a smooth single drum, smooth tandem roller or pneumatic tyre roller in combination with a grader, a water truck to achieve the desired flat surface with the right moisture content for optimum compaction. Once the road base is compacted, the smooth single drum compactor is no longer used on the road surface; the final wear course of asphalt concrete is laid using a paver and compacted using a tandem smooth drum roller, a three-point roller or a pneumatic tyre roller. Three point rollers on asphalt were common once and are still used, but tandem vibrating rollers are the usual choice now, with the pneumatic tyre roller's kneading action being the last roller to seal off the surface. Rollers are used in landfill compaction; such compactors have padfoot or "sheep's-foot" drums, do not achieve a smooth surface. The pads aid in compression, due to the smaller area contacting the ground.
The roller can be a simple drum with a handle, operated by one person, weighs 100 pounds, or as large as a ride-on road roller weighing 22 short tons and costing more than US$150,000. A landfill unit may weigh 59 short tons.

The euro is the official currency of 19 of the 28 member states of the European Union. This group of states is known as the eurozone or euro area, counts about 343 million citizens as of 2019; the euro is the second largest and second most traded currency in the foreign exchange market after the United States dollar. The euro is subdivided into 100 cents; the currency is used by the institutions of the European Union, by four European microstates that are not EU members, as well as unilaterally by Montenegro and Kosovo. Outside Europe, a number of special territories of EU members use the euro as their currency. Additionally, 240 million people worldwide as of 2018 use currencies pegged to the euro; the euro is the second largest reserve currency as well as the second most traded currency in the world after the United States dollar. As of August 2018, with more than €1.2 trillion in circulation, the euro has one of the highest combined values of banknotes and coins in circulation in the world, having surpassed the U.
S. dollar. The name euro was adopted on 16 December 1995 in Madrid; the euro was introduced to world financial markets as an accounting currency on 1 January 1999, replacing the former European Currency Unit at a ratio of 1:1. Physical euro coins and banknotes entered into circulation on 1 January 2002, making it the day-to-day operating currency of its original members, by March 2002 it had replaced the former currencies. While the euro dropped subsequently to US$0.83 within two years, it has traded above the U. S. dollar since the end of 2002, peaking at US$1.60 on 18 July 2008. In late 2009, the euro became immersed in the European sovereign-debt crisis, which led to the creation of the European Financial Stability Facility as well as other reforms aimed at stabilising and strengthening the currency; the euro is managed and administered by the Frankfurt-based European Central Bank and the Eurosystem. As an independent central bank, the ECB has sole authority to set monetary policy; the Eurosystem participates in the printing and distribution of notes and coins in all member states, the operation of the eurozone payment systems.
The 1992 Maastricht Treaty obliges most EU member states to adopt the euro upon meeting certain monetary and budgetary convergence criteria, although not all states have done so. The United Kingdom and Denmark negotiated exemptions, while Sweden turned down the euro in a 2003 referendum, has circumvented the obligation to adopt the euro by not meeting the monetary and budgetary requirements. All nations that have joined the EU since 1993 have pledged to adopt the euro in due course. Since 1 January 2002, the national central banks and the ECB have issued euro banknotes on a joint basis. Euro banknotes do not show. Eurosystem NCBs are required to accept euro banknotes put into circulation by other Eurosystem members and these banknotes are not repatriated; the ECB issues 8% of the total value of banknotes issued by the Eurosystem. In practice, the ECB's banknotes are put into circulation by the NCBs, thereby incurring matching liabilities vis-à-vis the ECB; these liabilities carry interest at the main refinancing rate of the ECB.
The other 92% of euro banknotes are issued by the NCBs in proportion to their respective shares of the ECB capital key, calculated using national share of European Union population and national share of EU GDP weighted. The euro is divided into 100 cents. In Community legislative acts the plural forms of euro and cent are spelled without the s, notwithstanding normal English usage. Otherwise, normal English plurals are sometimes used, with many local variations such as centime in France. All circulating coins have a common side showing the denomination or value, a map in the background. Due to the linguistic plurality in the European Union, the Latin alphabet version of euro is used and Arabic numerals. For the denominations except the 1-, 2- and 5-cent coins, the map only showed the 15 member states which were members when the euro was introduced. Beginning in 2007 or 2008 the old map is being replaced by a map of Europe showing countries outside the Union like Norway, Belarus, Russia or Turkey.
The 1-, 2- and 5-cent coins, keep their old design, showing a geographical map of Europe with the 15 member states of 2002 raised somewhat above the rest of the map. All common sides were designed by Luc Luycx; the coins have a national side showing an image chosen by the country that issued the coin. Euro coins from any member state may be used in any nation that has adopted the euro; the coins are issued in denominations of €2, €1, 50c, 20c, 10c, 5c, 2c, 1c. To avoid the use of the two smallest coins, some cash transactions are rounded to the nearest five cents in the Netherlands and Ireland and in Finland; this practice is discouraged by the Commission, as is the practice of certain shops of refusing to accept high-value euro notes. Commemorative coins with €2 face value have been issued with changes to the design of the national side of the coin; these include both issued coins, such as the €2 commemorative coin for the fiftieth anniversary of the signing of the Treaty of Rome, nationally i
Germany the Federal Republic of Germany, is a country in Central and Western Europe, lying between the Baltic and North Seas to the north, the Alps to the south. It borders Denmark to the north and the Czech Republic to the east and Switzerland to the south, France to the southwest, Luxembourg and the Netherlands to the west. Germany includes 16 constituent states, covers an area of 357,386 square kilometres, has a temperate seasonal climate. With 83 million inhabitants, it is the second most populous state of Europe after Russia, the most populous state lying in Europe, as well as the most populous member state of the European Union. Germany is a decentralized country, its capital and largest metropolis is Berlin, while Frankfurt serves as its financial capital and has the country's busiest airport. Germany's largest urban area is the Ruhr, with its main centres of Essen; the country's other major cities are Hamburg, Cologne, Stuttgart, Düsseldorf, Dresden, Bremen and Nuremberg. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity.
A region named Germania was documented before 100 AD. During the Migration Period, the Germanic tribes expanded southward. Beginning in the 10th century, German territories formed a central part of the Holy Roman Empire. During the 16th century, northern German regions became the centre of the Protestant Reformation. After the collapse of the Holy Roman Empire, the German Confederation was formed in 1815; the German revolutions of 1848–49 resulted in the Frankfurt Parliament establishing major democratic rights. In 1871, Germany became a nation state when most of the German states unified into the Prussian-dominated German Empire. After World War I and the revolution of 1918–19, the Empire was replaced by the parliamentary Weimar Republic; the Nazi seizure of power in 1933 led to the establishment of a dictatorship, the annexation of Austria, World War II, the Holocaust. After the end of World War II in Europe and a period of Allied occupation, Austria was re-established as an independent country and two new German states were founded: West Germany, formed from the American and French occupation zones, East Germany, formed from the Soviet occupation zone.
Following the Revolutions of 1989 that ended communist rule in Central and Eastern Europe, the country was reunified on 3 October 1990. Today, the sovereign state of Germany is a federal parliamentary republic led by a chancellor, it is a great power with a strong economy. As a global leader in several industrial and technological sectors, it is both the world's third-largest exporter and importer of goods; as a developed country with a high standard of living, it upholds a social security and universal health care system, environmental protection, a tuition-free university education. The Federal Republic of Germany was a founding member of the European Economic Community in 1957 and the European Union in 1993, it is part of the Schengen Area and became a co-founder of the Eurozone in 1999. Germany is a member of the United Nations, NATO, the G7, the G20, the OECD. Known for its rich cultural history, Germany has been continuously the home of influential and successful artists, musicians, film people, entrepreneurs, scientists and inventors.
Germany has a large number of World Heritage sites and is among the top tourism destinations in the world. The English word Germany derives from the Latin Germania, which came into use after Julius Caesar adopted it for the peoples east of the Rhine; the German term Deutschland diutisciu land is derived from deutsch, descended from Old High German diutisc "popular" used to distinguish the language of the common people from Latin and its Romance descendants. This in turn descends from Proto-Germanic *þiudiskaz "popular", derived from *þeudō, descended from Proto-Indo-European *tewtéh₂- "people", from which the word Teutons originates; the discovery of the Mauer 1 mandible shows that ancient humans were present in Germany at least 600,000 years ago. The oldest complete hunting weapons found anywhere in the world were discovered in a coal mine in Schöningen between 1994 and 1998 where eight 380,000-year-old wooden javelins of 1.82 to 2.25 m length were unearthed. The Neander Valley was the location where the first non-modern human fossil was discovered.
The Neanderthal 1 fossils are known to be 40,000 years old. Evidence of modern humans dated, has been found in caves in the Swabian Jura near Ulm; the finds included 42,000-year-old bird bone and mammoth ivory flutes which are the oldest musical instruments found, the 40,000-year-old Ice Age Lion Man, the oldest uncontested figurative art discovered, the 35,000-year-old Venus of Hohle Fels, the oldest uncontested human figurative art discovered. The Nebra sky disk is a bronze artefact created during the European Bronze Age attributed to a site near Nebra, Saxony-Anhalt, it is part of UNESCO's Memory of the World Programme. The Germanic tribes are thought to date from the Pre-Roman Iron Age. From southern Scandinavia and north Germany, they expanded south and west from the 1st century BC, coming into contact with the Celtic tribes of Gaul as well
