The World Portal

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...)

World history or global history as a field of historical study examines history from a global perspective. It emerged centuries ago; some leading practitioners have included Voltaire (1694–1778), Hegel (1770–1831), Karl Marx (1818–1883), Oswald Spengler (1880–1936), and Arnold J. Toynbee (1889–1975). The field became much more active (in terms of university teaching, textbooks, scholarly journals, and academic associations) in the late 20th century.

It is not to be confused with comparative history, which, like world history, deals with the history of multiple cultures and nations, but does not do so on a global scale. World historians use a thematic approach, with two major focal points: integration (how processes of world history have drawn people of the world together) and difference (how patterns of world history reveal the diversity of the human experience).

A megacity is a very large city, typically with a population of more than 10 million people. The United Nations Department of Economic and Social Affairs (UN DESA) in its 2018 "World Urbanization Prospects" report defines megacities as urban agglomerations with over 10 million inhabitants. A University of Bonn report holds that they are "usually defined as metropolitan areas with a total population of 10 million or more people". Elsewhere in other sources, from five to eight million is considered the minimum threshold, along with a population density of at least 2,000 per square kilometre. The terms conurbation, metropolis, and metroplex are also applied to the latter.

The total number of megacities in the world varies between different sources and their publication dates. The world had 32 according to EU Global Human Settlement Layer (in 2024), 33 according to UN DESA (in 2018), 39 according to the OECD, 44 according to Demographia (in 2023), and 45 according to CityPopulation.de (in 2023). In total, 53 unique places are mentioned as megacities across these sources. A good percentage of these urban agglomerations are in China and India. The other four countries with more than one megacity are Brazil, Japan, Pakistan, and the United States. African megacities are present in Nigeria, Egypt, South Africa, Angola and the DRC; European megacities are present in Russia, France, the United Kingdom, and Turkey (also in Asia); megacities can be found in Latin America in the countries of Brazil, Mexico, Colombia, Peru, and Argentina.

Globalism has multiple meanings. In political science, it is used to describe "attempts to understand all of the interconnections of the modern world—and to highlight patterns that underlie (and explain) them". While primarily associated with world-systems, it can be used to describe other global trends. The concept of globalism is also classically used to focus on ideologies of globalization (the subjective meanings) instead of its processes (the objective practices); in this sense, "globalism" is to globalization what "nationalism" is to nationalization.

Globalism as a concept dates from the 1940s. In the 21st century, the term "the globalists" was popularized by Alex Jones, and used interchangeably with the concepts of a New World Order and the deep state. The term is now frequently used as a pejorative by far-right movements and conspiracy theorists. It is sometimes associated with antisemitism, as antisemites frequently appropriate the term "Globalist" to refer to Jews. (Full article...)

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 International Bank Account Number (IBAN) is an internationally agreed upon system of identifying bank accounts across national borders to facilitate the communication and processing of cross border transactions with a reduced risk of transcription errors. An IBAN uniquely identifies the account of a customer at a financial institution. It was originally adopted by the European Committee for Banking Standards (ECBS) and since 1997 as the international standard ISO 13616 under the International Organization for Standardization (ISO). The current version is ISO 13616:2020, which indicates the Society for Worldwide Interbank Financial Telecommunication (SWIFT) as the formal registrar. Initially developed to facilitate payments within the European Union, it has been implemented by most European countries and numerous countries in other parts of the world, mainly in the Middle East and the Caribbean. By July 2024, 88 countries were using the IBAN numbering system.

The IBAN consists of up to 34 alphanumeric characters comprising a country code; two check digits; and a number that includes the domestic bank account number, branch identifier, and potential routing information. The check digits enable a check of the bank account number to confirm its integrity before submitting a transaction. (Full article...)

The earliest known world maps date to classical antiquity, the oldest examples of the 6th to 5th centuries BCE still based on the flat Earth paradigm. World maps assuming a spherical Earth first appear in the Hellenistic period. The developments of Greek geography during this time, notably by Eratosthenes and Posidonius culminated in the Roman era, with Ptolemy's world map (2nd century CE), which would remain authoritative throughout the Middle Ages. Since Ptolemy, knowledge of the approximate size of the Earth allowed cartographers to estimate the extent of their geographical knowledge, and to indicate parts of the planet known to exist but not yet explored as terra incognita.

With the Age of Discovery, during the 15th to 18th centuries, world maps became increasingly accurate; exploration of Antarctica, Australia, and the interior of Africa by western mapmakers was left to the 19th and early 20th century. (Full article...)

The United Nations (UN) is the global intergovernmental organization established by the signing of the UN Charter on 26 June 1945 with the articulated mission of maintaining international peace and security, to develop friendly relations among states, to promote international cooperation, and to serve as a centre for harmonizing the actions of states in achieving those goals.

The United Nations headquarters is located in New York City, with several other offices located in Geneva, Nairobi, Vienna, and The Hague. The UN comprises six principal organizations: the General Assembly, the Security Council, the Economic and Social Council, the International Court of Justice, the Secretariat, and the Trusteeship Council which, together with several specialized agencies and related agencies, make up the United Nations System. There are in total 193 member states and 2 observer states. (Full article...)

Manila skyline viewed from Intramuros

Manila, officially the City of Manila, is the capital and second-most populous city of the Philippines after Quezon City, with a population of 1,902,590 people in 2024. Located on the eastern shore of Manila Bay on the island of Luzon, it is classified as a highly urbanized city. With 43,611.5 inhabitants per square kilometer (112,953/sq mi), Manila is one of the world's most densely populated cities proper.^[1]

Manila was the first chartered city in the country, designated by Philippine Commission Act No. 183 on July 31, 1901. It became autonomous with the passage of Republic Act No. 409, "The Revised Charter of the City of Manila", on June 18, 1949. Manila is considered to be part of the world's original set of global cities because its commercial networks were the first to extend across the Pacific Ocean and connect Asia with the Spanish Americas through the galleon trade. This marked the first time an uninterrupted chain of trade routes circling the planet had been established. (Full article...)

Wonders of the World -

The Seven Wonders of the Ancient World, also known as the Seven Wonders of the World or simply the Seven Wonders, is a list of seven notable structures present during classical antiquity, first established in the 1572 publication Octo Mundi Miracula using a combination of historical sources.

The seven traditional wonders are the Great Pyramid of Giza, the Colossus of Rhodes, the Lighthouse of Alexandria, the Mausoleum at Halicarnassus, the Temple of Artemis, the Statue of Zeus at Olympia, and the Hanging Gardens of Babylon. Using modern-day countries, two of the wonders were located in Greece, two in Turkey, two in Egypt, and one in Iraq. Of the seven wonders, only the Pyramid of Giza, which is also by far the oldest of the wonders, remains standing, while the others have been destroyed over the centuries. There is scholarly debate over the exact nature of the Hanging Gardens, and there is doubt as to whether they existed at all. (Full article...)

This is a list of the nationally designated protected areas of China. There are many forms of protected areas in China. Based on their relative importance, each type of protected area can be further graded into two to three levels (national, provincial and prefectural/county level). Nevertheless, the highest rank for "pocket nature preserve" (social and mass-based), "no-hunting area", "no-fishing area", "no-logging area", "wild medicinal material resources conservation area", "crop germplasm resources conservation area", "forest tree germplasm resources conservation area" or "source water protection area" is practically restricted to provincial level. The local government at county level is also responsible for the delimitation and declaration of "basic farmland protection area" and "basic grassland".

Take note that many protected areas in China have multiple official designations, and the statutory boundaries of these multi-designated PAs may be identical or may vary one from the other. For instance, the boundaries of Huangshan NSHA coincide with those of the Huangshan NGP, whereas Fujian province's Wuyi Mountains NNR, NSHA and NFP are adjacent to each other. In Heilongjiang, 27,642.14 hectares out of 115,340.27 hectares of Huzhong NFP are intersected with the experiment zone of Huzhong NNR. (Full article...)
