The world

The Blue Marble, a photograph of the planet Earth made on 7 December 1972 by the crew of the Apollo 17 spacecraft.

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...)

  Artist's concept of the Earth 5–7.5 billion years from now, when the Sun has become a red giant

  
  
  While the future cannot be predicted with certainty, present understanding in various scientific fields allows for the prediction of some far-future events, if only in the broadest outline. These fields include astrophysics, which studies how planets and stars form, interact and die; particle physics, which has revealed how matter behaves at the smallest scales; evolutionary biology, which studies how life evolves over time; plate tectonics, which shows how continents shift over millennia; and sociology, which examines how human societies and cultures evolve.
  
  These timelines begin at the start of the 4th millennium in 3001 CE, and continue until the furthest and most remote reaches of future time. They include alternative future events that address unresolved scientific questions, such as whether humans will become extinct, whether the Earth survives when the Sun expands to become a red giant and whether proton decay will be the eventual end of all matter in the universe.

  Hotspots of sulfate aerosol pollution in 2005–2007 are highlighted in orange. Such sulfates rarely occur naturally outside of volcanic activity, and their increased levels are the main cause of global dimming.

  
  Global dimming is a decline in the amount of sunlight reaching the Earth's surface. It is caused by atmospheric particulate matter, predominantly sulfate aerosols, which are components of air pollution. Global dimming was observed soon after the first systematic measurements of solar irradiance began in the 1950s. This weakening of visible sunlight proceeded at the rate of 4–5% per decade until the 1980s. During these years, air pollution increased due to post-war industrialization. Solar activity did not vary more than the usual during this period.
  
  Aerosols have a cooling effect on the earth's atmosphere, and global dimming has masked the extent of global warming experienced to date, with the most polluted regions even experiencing cooling in the 1970s. Global dimming has interfered with the water cycle by lowering evaporation, and thus has probably reduced rainfall in certain areas. It may have weakened the Monsoon of South Asia and caused the entire tropical rain belt to shift southwards between 1950 and 1985, with a limited recovery afterwards. Record levels of particulate pollution in the Northern Hemisphere caused or at least exacerbated the monsoon failure behind the 1984 Ethiopian famine. (Full article...)

  Gerardus Mercator 1512–1594

  
  
  The Mercator world map of 1569 is titled Nova et Aucta Orbis Terrae Descriptio ad Usum Navigantium Emendate Accommodata (Renaissance Latin for "New and more complete representation of the terrestrial globe properly adapted for use in navigation"). The title shows that Gerardus Mercator aimed to present contemporary knowledge of the geography of the world and at the same time 'correct' the chart to be more useful to sailors. This 'correction', whereby constant bearing sailing courses on the sphere (rhumb lines) are mapped to straight lines on the plane map, characterizes the Mercator projection. While the map's geography has been superseded by modern knowledge, its projection proved to be one of the most significant advances in the history of cartography, inspiring the 19th century map historian Adolf Nordenskiöld to write "The master of Rupelmonde stands unsurpassed in the history of cartography since the time of Ptolemy." The projection heralded a new era in the evolution of navigation maps and charts and it is still their basis.The map is inscribed with a great deal of text. The framed map legends (or cartouches) cover a wide variety of topics: a dedication to his patron and a copyright statement; discussions of rhumb lines; great circles and distances; comments on some of the major rivers; accounts of fictitious geography of the north pole and the southern continent. The full Latin texts and English translations of all the legends are given below. Other minor texts are sprinkled about the map. They cover such topics as the magnetic poles, the prime meridian, navigational features, minor geographical details, the voyages of discovery and myths of giants and cannibals. These minor texts are also given below. (Full article...)

  Cover of French first edition 1873

  
  Around the World in Eighty Days (French: Le Tour du monde en quatre-vingts jours) is an adventure novel by the French writer Jules Verne, first published in French in 1872. In the story, Phileas Fogg of London and his newly employed French valet Passepartout attempt to circumnavigate the world in 80 days on a wager of £20,000 (equivalent to £2.3 million in 2023) set by his friends at the Reform Club. It is one of Verne's most acclaimed works. (Full article...)

  The Paris Agreement (also called the Paris Accords or Paris Climate Accords) is an international treaty on climate change that was signed in 2016. The treaty covers climate change mitigation, adaptation, and finance. The Paris Agreement was negotiated by 196 parties at the 2015 United Nations Climate Change Conference near Paris, France. As of February 2023, 195 members of the United Nations Framework Convention on Climate Change (UNFCCC) are parties to the agreement. Of the three UNFCCC member states which have not ratified the agreement, the only major emitter is Iran. The United States, the second largest emitter, withdrew from the agreement in 2020, rejoined in 2021, and announced its withdrawal again in 2025.
  
  The Paris Agreement has a long-term temperature goal which is to keep the rise in global surface temperature to well below 2 °C (3.6 °F) above pre-industrial levels. The treaty also states that preferably the limit of the increase should only be 1.5 °C (2.7 °F). These limits are defined as averages of the global temperature as measured over many years.

  A typical British bank statement header (from a fictitious bank), showing the location of the account's IBAN

  
  
  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...)

  A world-system is a socioeconomic system, under systems theory, that encompasses part or all of the globe, detailing the aggregate structural result of the sum of the interactions between polities. World-systems are usually larger than single states, but do not have to be global. The Westphalian System is the preeminent world-system operating in the contemporary world, denoting the system of sovereign states and nation-states produced by the Westphalian Treaties in 1648. Several world-systems can coexist, provided that they have little or no interaction with one another. Where such interactions becomes significant, separate world-systems merge into a new, larger world-system. Through the process of globalization, the modern world has reached the state of one dominant world-system, but in human history there have been periods where separate world-systems existed simultaneously, according to Janet Abu-Lughod. The most well-known version of the world-system approach has been developed by Immanuel Wallerstein. A world-system is a crucial element of the world-system theory, a multidisciplinary, macro-scale approach to world history and social change. (Full article...)

Hangzhou is the capital city of the Chinese province of Zhejiang. With a population of 13 million, the municipality comprises ten districts, two counties, and one county-level city in northwestern Zhejiang. It is situated at the head of Hangzhou Bay and the estuary of the Qiantang River.

Established as a county seat in 221 BC, Hangzhou later served as the capital of the Wuyue Kingdom (923–997) and the Southern Song dynasty (1138–1276). The city has three UNESCO World Heritage Sites, which are the West Lake Cultural Landscape, the Grand Canal, and the Archaeological Ruins of Liangzhu City. (Full article...)

Countries of the world -

The Maldives, officially the Republic of Maldives, and historically known as the Maldive Islands, is an archipelagic country in South Asia located in the Indian Ocean. The Maldives is southwest of Sri Lanka and India, about 750 kilometres (470 miles; 400 nautical miles) from the Asian continent's mainland. The Maldives' chain of 26 atolls stretches across the equator from Ihavandhippolhu Atoll in the north to Addu Atoll in the south.

The Maldives is the smallest country in Asia. Its land area is only 298 square kilometres (115 sq mi), but this is spread over roughly 90,000 square kilometres (35,000 sq mi) of the sea, making it one of the world's most spatially dispersed sovereign states. With a population of 515,132 in the 2022 census, it is the second least populous country in Asia and the ninth-smallest country by area, but also one of the most densely populated countries. The Maldives has an average ground-level elevation of around 1.5 metres (4 ft 11 in) above sea level, and a highest natural point of only 2.4 metres (7 ft 10 in), making it the world's lowest-lying country. Some sources state the highest point, Mount Villingili, as 5.1 metres or 17 feet. (Full article...)

Wonders of the World -

The Seven Wonders of Wales (Welsh: Saith Rhyfeddod Cymru) is a traditional list of notable landmarks in north Wales, commemorated in an anonymously written rhyme:

The rhyme is usually supposed to have been written sometime in the late 18th or early 19th century by an English visitor to North Wales. The specific number of wonders may have varied over the years: the antiquary Daines Barrington, in a letter written in 1770, refers to Llangollen Bridge as one of the "five wonders of Wales, though like the seven wonders of Dauphiny, they turn out to be no wonders at all out of the Principality".

  Andohahela National Park in southern Madagascar

  
  The national parks of Madagascar include all officially recognized protected areas as of 2015. The protected areas network of Madagascar is managed by the Madagascar National Parks Association (PNM-ANGAP). The network includes three types of protected areas: Strict Nature Reserves (IUCN category Ia), National Parks (IUCN category II) and Wildlife Reserves (IUCN category IV). At the 2003 IUCN World Parks Congress in Durban, the Malagasy President, Marc Ravalomanana, announced an initiative to more than triple the area under protection from approximately 17,000 km² (6,600 sq mi) to over 60,000 km² (23,000 sq mi) (from 3% to 10% of Madagascar's area). This "Durban Vision", as it has been dubbed, involved broadening the definition of protected areas in the country and legislation has been passed to allow the creation of four new categories of protected area: Natural Parks (IUCN category II), Natural Monuments (IUCN category III), Protected Landscapes (IUCN category V), and Natural Resource Reserves (IUCN category VI). As well as allowing these new objectives for protected areas management, the new legislation also provided for entities other than PNM-ANGAP to manage protected areas, such as government ministries, community associations, NGOs and other civil society organizations, and the private sector.
