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 "the 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...)

  • Image 1 Global urbanization map showing the percentage of urbanization and the biggest global population centres per country in 2018, based on UN estimates. Urbanization (or urbanisation in British English) is the population shift from rural to urban areas, the corresponding decrease in the proportion of people living in rural areas, and the ways in which societies adapt to this change. It can also mean population growth in urban areas instead of rural ones. It is predominantly the process by which towns and cities are formed and become larger as more people begin to live and work in central areas. Although the two concepts are sometimes used interchangeably, urbanization should be distinguished from urban growth. Urbanization refers to the proportion of the total national population living in areas classified as urban, whereas urban growth strictly refers to the absolute number of people living in those areas. It is predicted that by 2050, about 64% of the developing world and 86% of the developed world will be urbanized. This is predicted to generate artificial scarcities of land, lack of drinking water, playgrounds and other essential resources for most urban dwellers. The predicted urban population growth is equivalent to approximately 3 billion urbanites by 2050, much of which will occur in Africa and Asia. Notably, the United Nations has also recently projected that nearly all global population growth from 2017 to 2030 will take place in cities, with about 1.1 billion new urbanites over the next 10 years. In the long term, urbanization is expected to significantly impact the quality of life in negative ways. (Full article...)

  • Image 2 Internationalism is a political principle that advocates greater political or economic cooperation among states and nations. It is associated with other political movements and ideologies, but can also reflect a doctrine, belief system, or movement in itself. Supporters of internationalism are known as internationalists and generally believe that humans should unite across national, political, cultural, racial, or class boundaries to advance their common interests, or that governments should cooperate because their mutual long-term interests are of greater importance than their short-term disputes.

Control is considered an important aspect of an MNC to distinguish it from international portfolio investment organizations, such as some international mutual funds that invest in corporations abroad solely to diversify financial risks. Most of the current largest and most influential companies are publicly traded multinational corporations, including Forbes Global 2000 companies. (Full article...)

  • Image 5 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.

  • Image 6 Early in the COVID-19 pandemic, convention centers (pictured here) were deemed to be ideal sites for temporary hospitals, due to their existing infrastructure (electrical, water, sewage). Hotels and dormitories were also considered appropriate because they can use negative pressure technology. A pandemic (/pænˈdɛmɪk/ pan-DEM-ik) is an epidemic of an infectious disease that has a sudden increase in cases and spreads across a large region, for instance multiple continents or worldwide, affecting a substantial number of individuals. Widespread endemic diseases with a stable number of infected individuals such as recurrences of seasonal influenza are generally excluded as they occur simultaneously in large regions of the globe rather than being spread worldwide. Throughout human history, there have been a number of pandemics of diseases such as smallpox. The Black Death, caused by the Plague, caused the deaths of up to half of the population of Europe in the 14th century. The term pandemic had not been used then, but was used for later epidemics, including the 1918 H1N1 influenza A pandemic—more commonly known as the Spanish flu—which is the deadliest pandemic in history. The most recent pandemics include the HIV/AIDS pandemic, the 2009 swine flu pandemic and the COVID-19 pandemic. Almost all these diseases still circulate among humans though their impact now is often far less. (Full article...)

Downtown Kinshasa

Kinshasa (/kɪnˈʃɑːsə/; French: [kinʃasa]; Lingala: Kinsásá), formerly named Léopoldville from 1881–1966 (Dutch: Leopoldstad), is the capital and largest city of the Democratic Republic of the Congo. Kinshasa is one of the world's fastest-growing megacities, with an estimated population of 17 million in 2024. It is the most densely populated city in the DRC, the most populous city and third-largest metropolitan area in Africa, and the world's twenty-second most populous city and fourth-most populous capital city. It is the leading economic, political, and cultural center of the DRC, housing several industries including manufacturing, telecommunications, banking, and entertainment. The city also hosts some of DRC's significant institutional buildings, such as the People's Palace, Palace of the Nation, Court of Cassation, Constitutional Court, African Union City, Marble Palace, Martyrs Stadium, Government House, Kinshasa Financial Center, and other national departments and agencies.

The Kinshasa site has been inhabited by Bantus (Teke, Humbu [fr]) for centuries and was known as Nshasa before transforming into a commercial hub during the 19th and 20th centuries. The city was named Léopoldville by Henry Morton Stanley in honor of Leopold II of Belgium. The name was changed to Kinshasa in 1966 during Mobutu Sese Seko's Zairianisation campaign as a tribute to Nshasa village. Covering 9,965 square kilometers, Kinshasa stretches along the southern shores of the Pool Malebo on the Congo River. It forms an expansive crescent across flat, low-lying terrain at an average altitude of about 300 meters. Kinshasa borders the Mai-Ndombe Province, Kwilu Province, and Kwango Province to the east; the Congo River delineates its western and northern perimeters, constituting a natural border with the Republic of the Congo; to the south lies the Kongo Central Province. Across the river sits Brazzaville, the smaller capital of the neighboring Republic of the Congo, forming the world's second-closest pair of capital cities despite being separated by a four-kilometer-wide unbridged span of the Congo River.

Paraguay, officially the Republic of Paraguay, is a landlocked country in South America. It is bordered by Argentina to the south and southwest, Brazil to the east and northeast, and Bolivia to the northwest. It has a population of around 6.1 million, nearly 2.3 million of whom live in the capital and largest city of Asunción, and its surrounding metro area.

Spanish conquistadores arrived in 1524, and in 1537 established the city of Asunción, the first capital of the Governorate of the Río de la Plata. During the 17th century, Paraguay was the center of Jesuit missions, where the native Guaraní people were converted to Christianity and introduced to European culture. After the expulsion of the Jesuits from Spanish territories in 1767, Paraguay increasingly became a peripheral colony. Following independence from Spain in the early 19th century, Paraguay was ruled by a series of authoritarian governments. This period ended with the disastrous Paraguayan War (1864–1870), during which the country lost half its prewar population and around 25–33% of its territory. In the 20th century, Paraguay faced another major international conflict—the Chaco War (1932–1935) against Bolivia—in which Paraguay prevailed. The country came under a succession of military dictators, culminating in the 35-year regime of Alfredo Stroessner, which lasted until his overthrow in 1989 by an internal military coup. This marked the beginning of Paraguay's current democratic era. (Full article...)
