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...)

The term "new world order" refers to a new period of history evidencing dramatic change in world political thought and the balance of power in international relations. Despite varied interpretations of this term, it is commonly associated with the notion of world governance.

The phrase "new world order" or similar language was used in the period toward the end of the First World War in relation to Woodrow Wilson's vision for international peace; Wilson called for a League of Nations to prevent aggression and conflict. In some instances when Franklin D. Roosevelt used the phrase "new world order", or "new order in the world" it was to refer to Axis powers plans for world domination. Although Roosevelt and Harry S. Truman may have been hesitant to use the phrase, commentators have applied the term retroactively to the order put in place by the World War II victors including the United Nations and the Bretton Woods system as a "new world order."

Second preliminary session of the World Summit Information Society, plenary meeting, 18–25 February 2005, UN building, Geneva, Switzerland.

The World Summit on the Information Society (WSIS) was a two-phase United Nations-sponsored summit on information, communication and, in broad terms, the information society that took place in 2003 in Geneva and in 2005 in Tunis. WSIS Forums have taken place periodically since then. One of the Summit's chief aims is to bridge the global digital divide separating rich countries from poor countries by increasing internet accessibility in the developing world. The conferences established 17 May as World Information Society Day.

The WSIS+10 Process marked the ten-year milestone since the 2005 Summit. In 2015, the stocktaking process culminated with a High-Level meeting of the UN General Assembly on 15 and 16 December in New York. The United Nations General Assembly will conclude the WSIS+20 review in December 2025. (Full article...)

The Hereford mappa mundi, a map of the world with Jerusalem at its centre

The Hereford Mappa Mundi (Latin: mappa mundi, map of the world) is the largest medieval map still known to exist, depicting the known world. It is a religious rather than literal depiction, featuring heaven, hell and the path to salvation. Dating from c. 1300 AD, the map is drawn in a form deriving from the T and O pattern. It is displayed at Hereford Cathedral in Hereford, England. The map was created as an intricate work of art rather than as a navigational tool. Sources for the information presented on the map include the Alexander tradition, medieval bestiaries and legends of monstrous races, as well as the Bible.

Although the evidence is circumstantial, recent work links the map with the promotion of the cult of Thomas de Cantilupe. Others link the map to a justification of the expulsion of Jewry from England. Potentially antisemitic images include a horned Moses and a depiction of Jews worshipping the Golden Calf in the form of a Saracen devil. The map may also reflect very patriarchal views of women as inherently sinful, including figures such as the wife of Lot being turned into a pillar of salt for gazing at the city of Sodom. Cantilupe was known for his dislike of Jews; in historian Debra Strickland's opinion he was regarded as misogynistic even by the standards of his own time. (Full article...)

UN Trade and Development (UNCTAD) is an intergovernmental organization within the United Nations Secretariat that promotes the interests of developing countries in world trade. It was established in 1964 by the United Nations General Assembly (UNGA) as the United Nations Conference on Trade and Development but rebranded to its current name on the occasion of its 60th anniversary in 2024. It reports to both the General Assembly and the United Nations Economic and Social Council (ECOSOC). UNCTAD is composed of 195 member states and works with non-governmental organizations worldwide; its permanent secretariat is at UNOG in Geneva, Switzerland.

The primary objective of UNCTAD is to formulate policies relating to all aspects of development, including trade, aid, transport, finance and technology. It was created in response to concerns among developing countries that existing international institutions like GATT (since replaced by the World Trade Organization), the International Monetary Fund (IMF), and the World Bank were not properly organized to handle the particular problems of developing countries; UNCTAD would provide a forum where developing nations could discuss and address problems relating to their economic development.

The Arab world (Arabic: اَلْعَالَمُ الْعَرَبِيُّ al-ʿālam al-ʿarabī), formally the Arab homeland (اَلْوَطَنُ الْعَرَبِيُّ al-waṭan al-ʿarabī), also known as the Arab nation (اَلْأُمَّةُ الْعَرَبِيَّةُ al-ummah al-ʿarabiyyah), the Arabsphere, or the Arab states, comprises a large group of countries, mainly located in West Asia and North Africa. While the majority of people in the Arab world are ethnically Arab, there are also significant populations of other ethnic groups such as Berbers, Kurds, Somalis and Nubians, among other groups. Arabic is used as the lingua franca throughout the Arab world.

The Arab world is at its minimum defined as the 19 states where Arabs form at least a plurality of the population. At its maximum it consists of the 22 members of the Arab League, an international organization, which on top of the 19 plurality Arab states also includes the Bantu-speaking Comoros, and the Cushitic-speaking Djibouti and Somalia. The region stretches from the Atlantic Ocean in the west to the Arabian Sea in the east, and from the Mediterranean Sea in the north to the Indian Ocean in the southeast. The eastern part of the Arab world is known as the Mashriq, and the western part as the Maghreb. (Full article...)

The map of the mouth of the River Amazon

The International Map of the World (IMW; also the Millionth Map of the World, after its scale of 1:1 000 000) was a project to create a complete map of the world according to internationally agreed standards. It was first proposed by the German geographer Albrecht Penck in 1891.

The Central Bureau of the Map of the World was established in London. After the Second World War, UNESCO took over the project. By 1953, 400 sheets had been produced. The completed sheets became outdated before the project had produced a full set of maps, and by the 1960s was being dismissed as being of no practical use. The project was no longer monitored by the 1990s. (Full article...)

Map of Pangaea around 250 million years ago, at the beginning of the Triassic

Pangaea or Pangea (/pænˈdʒiːə/ pan-JEE-ə) was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It assembled from the earlier continental units of Gondwana, Euramerica and Siberia during the Carboniferous period approximately 335 million years ago, and began to break apart about 200 million years ago, at the end of the Triassic and beginning of the Jurassic. Pangaea was C-shaped, with the bulk of its mass stretching between Earth's northern and southern polar regions and surrounded by the superocean Panthalassa and the Paleo-Tethys and subsequent Tethys Oceans. Pangaea is the most recent supercontinent to have existed and was the first to be reconstructed by geologists. (Full article...)

Wonders of the World - show another

The Seven Wonders of Canada was a 2007 competition sponsored by CBC Television's The National and CBC Radio One's Sounds Like Canada. They sought to determine Canada's "seven wonders" by receiving nominations from viewers, and then from on-line voting of the short list. After the vote, a panel of judges, Ra McGuire, Roy MacGregor and Roberta L. Jamieson, picked the winners based on geographic and poetic criteria. Their seven picks were revealed on The National on June 7, 2007, making the official Seven Wonders of Canada, the Canoe, the Igloo, Niagara Falls, Old Quebec City, Pier 21 Halifax, Prairie Skies, and the Rockies. CBC anchor Peter Mansbridge commented on the top winner, “it’s hard to imagine Canada being Canada without the canoe. Explorers, missionaries, fur traders and First Nations—they’re all linked by this subtle and simple craft. To many, the quintessential Canadian experience begins by picking up a paddle. That’s why the canoe is one of the seven wonders” (Osler 2014). There were over 25,000 nominations and 1 million votes cast, according to the CBC website. The top audience votes were the Sleeping Giant, Niagara Falls, the Bay of Fundy, Nahanni National Park Reserve, the Northern Lights, the Rockies, and the Cabot Trail. The CBC website has a dedicated section for the Seven Wonders of Canada (https://www.cbc.ca/sevenwonders/index.html). (Full article...)

Many parts of Scotland are protected in accordance with a number of national and international designations because of their environmental, historical or cultural value. Protected areas can be divided according to the type of resource which each seeks to protect. NatureScot has various roles in the delivery of many environmental designations in Scotland, i.e. those aimed at protecting flora and fauna, scenic qualities and geological features. Historic Environment Scotland is responsible for designations that protect sites of historic and cultural importance. Some international designations, such as World Heritage Sites, can cover both categories of site.

The various designations overlap considerably with many protected areas being covered by multiple designations with different boundaries. (Full article...)
