The world is the totality of entities, the whole of reality, or everything that exists. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of parts.
In scientific cosmology, the world or universe is commonly defined as "[t]he totality of all space and time; all that is, has been, and will be". Theories of modality talk of possible worlds as complete and consistent ways how things could have been. Phenomenology, starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In philosophy of mind, the world is contrasted with the mind as that which is represented by the mind.
Theology conceptualizes the world in relation to God, for example, as God's creation, as identical to God or as the two being interdependent. In religions, there is a tendency to downgrade the material or sensory world in favor of a spiritual world to be sought through religious practice. A comprehensive representation of the world and our place in it, as is found in religions, is known as a worldview. Cosmogony is the field that studies the origin or creation of the world while eschatology refers to the science or doctrine of the last things or of the end of the world.
In various contexts, the term "world" takes a more restricted meaning associated, for example, with the Earth and all life on it, with humanity as a whole or with an international or intercontinental scope. In this sense, world history refers to the history of humanity as a whole and world politics is the discipline of political science studying issues that transcend nations and continents. Other examples include terms such as "world religion", "world language", "world government", "world war", "world population", "world economy", or "world championship". (Full article...)

A world war is an international conflict that involves most or all of the world's major powers. Conventionally, the term is reserved for two major international conflicts that occurred during the first half of the 20th century, World War I (1914–1918) and World War II (1939–1945), although some historians have also characterised other global conflicts as world wars, such as the Nine Years' War, the War of the Spanish Succession, the Seven Years' War, the French Revolutionary and Napoleonic Wars, the Cold War, and the War on Terror.

Image 2Global mental health is the international perspective on different aspects of mental health. It is 'the area of study, research and practice that places a priority on improving mental health and achieving equity in mental health for all people worldwide'. There is a growing body of criticism of the global mental health movement, and has been widely criticised as a neo-colonial or "missionary" project and as primarily a front for pharmaceutical companies seeking new clients for psychiatric drugs.
In theory, taking into account cultural differences and country-specific conditions, it deals with the epidemiology of mental disorders in different countries, their treatment options, mental health education, political and financial aspects, the structure of mental health care systems, human resources in mental health, and human rights issues among others.

A world map on the Winkel tripel projection,
a low-error map projection adopted by the National Geographic Society for reference maps
A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth. While this is true of any map, these distortions reach extremes in a world map. Many techniques have been developed to present world maps that address diverse technical and aesthetic goals.
Charting a world map requires global knowledge of the Earth, its oceans, and its continents. From prehistory through the Middle Ages, creating an accurate world map would have been impossible because less than half of Earth's coastlines and only a small fraction of its continental interiors were known to any culture. With exploration that began during the European Renaissance, knowledge of the Earth's surface accumulated rapidly, such that most of the world's coastlines had been mapped, at least roughly, by the mid-1700s and the continental interiors by the twentieth century.

The Human Development Index (HDI) is a statistical composite index of life expectancy, education (mean years of schooling completed and expected years of schooling upon entering the education system), and per capita income indicators, which is used to rank countries into four tiers of human development. A country scores a higher level of HDI when the lifespan is higher, the education level is higher, and the gross national income GNI (PPP) per capita is higher. It was developed by Pakistani economist Mahbub ul-Haq and was further used to measure a country's development by the United Nations Development Programme (UNDP)'s Human Development Report Office.
The 2010 Human Development Report introduced an Inequality-adjusted Human Development Index (IHDI). While the simple HDI remains useful, it stated that "the IHDI is the actual level of human development (accounting for this inequality), while the HDI can be viewed as an index of 'potential' human development (or the maximum level of HDI) that could be achieved if there was no inequality."

The global financial system is the worldwide framework of legal agreements, institutions, and both formal and informal economic action that together facilitate international flows of financial capital for purposes of investment and trade financing. Since emerging in the late 19th century during the first modern wave of economic globalization, its evolution is marked by the establishment of central banks, multilateral treaties, and intergovernmental organizations aimed at improving the transparency, regulation, and effectiveness of international markets. In the late 1800s, world migration and communication technology facilitated unprecedented growth in international trade and investment. At the onset of World War I, trade contracted as foreign exchange markets became paralyzed by money market illiquidity. Countries sought to defend against external shocks with protectionist policies and trade virtually halted by 1933, worsening the effects of the global Great Depression until a series of reciprocal trade agreements slowly reduced tariffs worldwide. Efforts to revamp the international monetary system after World War II improved exchange rate stability, fostering record growth in global finance.
A series of currency devaluations and oil crises in the 1970s led most countries to float their currencies. The world economy became increasingly financially integrated in the 1980s and 1990s due to capital account liberalization and financial deregulation. A series of financial crises in Europe, Asia, and Latin America followed with contagious effects due to greater exposure to volatile capital flows. The global financial crisis, which originated in the United States in 2007, quickly propagated among other nations and is recognized as the catalyst for the worldwide Great Recession. A market adjustment to Greece's noncompliance with its monetary union in 2009 ignited a sovereign debt crisis among European nations known as the Eurozone crisis. The history of international finance shows a U-shaped pattern in international capital flows: high prior to 1914 and after 1989, but lower in between. The volatility of capital flows has been greater since the 1970s than in previous periods. (Full article...) -

Istanbul is the largest city in Turkey, straddling the Bosporus Strait, the boundary between Europe and Asia. It is considered the country's economic, cultural and historic capital. The city has a population of over 15 million residents, comprising 19% of the population of Turkey, and is the most populous city in Europe and the world's fifteenth-largest city.
The city was founded as Byzantium in the 7th century BCE by Greek settlers from Megara. In 330 CE, the Roman emperor Constantine the Great made it his imperial capital, renaming it first as New Rome (Ancient Greek: Νέα Ῥώμη Nea Rhomē; Latin: Nova Roma) and then finally as Constantinople (Constantinopolis) after himself. In 1930, the city's name was officially changed to Istanbul, the Turkish rendering of εἰς τὴν Πόλιν eis tḕn Pólin 'to the City', the appellation Greek speakers used since the 11th century to colloquially refer to the city.

Slovakia (/sloʊˈvækiə, -ˈvɑːk-/ ⓘ; Slovak: Slovensko [ˈslɔʋenskɔ] ⓘ), officially the Slovak Republic (Slovak: Slovenská republika [ˈslɔʋenskaː ˈrepublika] ⓘ), 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, and the Czech Republic to the northwest. Slovakia's mostly mountainous territory spans about 49,000 square kilometres (19,000 sq mi), hosting a population exceeding 5.4 million. The capital and largest city is Bratislava, while the second largest city is Košice.
The Slavs arrived in the territory of the present-day Slovakia in the 5th and 6th centuries. From the late 6th century, parts of modern Slovakia were incorporated in the Avar Khaghanate. In the 7th century, the Slavs played a significant role in the creation of Samo's Empire. In the 9th century, the Avar Khaghanate dissolved, and the Slavs established the Principality of Nitra, which was later conquered by the Principality of Moravia, leading to the formation of Great Moravia. In the 10th century, after the dissolution of Great Moravia, the territory was integrated into the Principality of Hungary, which then became the Kingdom of Hungary in 1000. In 1241 and 1242, after the Mongol invasion of Europe, much of the territory was destroyed, but was recovered largely thanks to Béla IV.
