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 "[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...)

The World Chess Championship is played to determine the world champion in chess. The current world champion is Ding Liren, who defeated his opponent Ian Nepomniachtchi in the 2023 World Chess Championship. Magnus Carlsen, the previous world champion, had declined to defend his title.
The first event recognized as a world championship was the 1886 match between the two leading players in the world, Wilhelm Steinitz and Johannes Zukertort. Steinitz won, becoming the first world champion. From 1886 to 1946, the champion set the terms, requiring any challenger to raise a sizable stake and defeat the champion in a match in order to become the new world champion. Following the death of reigning world champion Alexander Alekhine in 1946, FIDE (the International Chess Federation) took over administration of the World Championship, beginning with the 1948 World Championship tournament. From 1948 to 1993, FIDE organized a set of tournaments to choose a new challenger every three years. In 1993, reigning champion Garry Kasparov broke away from FIDE, which led to a rival claimant to the title of World Champion for the next thirteen years. The titles were unified at the World Chess Championship 2006, and all subsequent matches have once again been administered by FIDE. (Full article...) -
Image 2The aftermath of World War II saw the rise of two global superpowers, the Soviet Union (USSR) and the United States (US). The aftermath of World War II was also defined by the rising threat of nuclear warfare, the creation and implementation of the United Nations as an intergovernmental organization, and the decolonization of Asia and Africa by European and East Asian powers, most notably by the United Kingdom, France, and Japan.
Once allies during World War II, the United States and the Soviet Union became competitors on the world stage and engaged in the Cold War, so called because it never resulted in overt, declared total war between the two powers. It was instead characterized by espionage, political subversion and proxy wars. Western Europe and Asia were rebuilt through the American Marshall Plan, whereas Central and Eastern Europe fell under the Soviet sphere of influence and eventually behind an "Iron Curtain". Europe was divided into a US-led Western Bloc and a USSR-led Eastern Bloc. Internationally, alliances with the two blocs gradually shifted, with some nations trying to stay out of the Cold War through the Non-Aligned Movement. The war also saw a nuclear arms race between the two superpowers; part of the reason that the Cold War never became a "hot" war was that the Soviet Union and the United States had nuclear deterrents against each other, leading to a mutually assured destruction standoff.

The ocean is the body of salt water that covers approx. 70.8% of Earth. In English, the term ocean also refers to any of the large bodies of water into which the world ocean is conventionally divided. Distinct names are used to identify five different areas of the ocean: Pacific, Atlantic, Indian, Antarctic/Southern, and Arctic. The ocean contains 97% of Earth's water and is the primary component of Earth's hydrosphere, thus the ocean is essential to life on Earth. The ocean influences climate and weather patterns, the carbon cycle, and the water cycle by acting as a huge heat reservoir.
Oceanographers split the ocean into vertical and horizontal zones based on physical and biological conditions. The pelagic zone is the open ocean's water column from the surface to the ocean floor. The water column is further divided into zones based on depth and the amount of light present. The photic zone starts at the surface and is defined to be "the depth at which light intensity is only 1% of the surface value" (approximately 200 m in the open ocean). This is the zone where photosynthesis can occur. In this process plants and microscopic algae (free floating phytoplankton) use light, water, carbon dioxide, and nutrients to produce organic matter. As a result, the photic zone is the most biodiverse and the source of the food supply which sustains most of the ocean ecosystem. Ocean photosynthesis also produces half of the oxygen in the Earth's atmosphere. Light can only penetrate a few hundred more meters; the rest of the deeper ocean is cold and dark (these zones are called mesopelagic and aphotic zones). The continental shelf is where the ocean meets dry land. It is more shallow, with a depth of a few hundred meters or less. Human activity often has negative impacts on the ecosystems within the continental shelf. (Full article...) -

The Hereford Mappa Mundi (Latin: mappa mundi) 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. The map is drawn in a form deriving from the T and O pattern, dating from c. 1300. It is displayed at Hereford Cathedral in Hereford, England. The map was created with the intent of its being appreciated 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 Monstrous races tradition, as well as the Bible.
Although the evidence is circumstantial, modern scholarship links the map with the promotion of the cult of Thomas de Cantilupe, and with 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 also seems to reflect very patriarchical 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 and was regarded as misogynistic even by the standards of his own time. (Full article...) -

World-systems theory (also known as world-systems analysis or the world-systems perspective) is a multidisciplinary approach to world history and social change which emphasizes the world-system (and not nation states) as the primary (but not exclusive) unit of social analysis. World-systems theorists argue that their theory explains the rise and fall of states, income inequality, social unrest, and imperialism.
"World-system" refers to the inter-regional and transnational division of labor, which divides the world into core countries, semi-periphery countries, and periphery countries. Core countries have higher-skill, capital-intensive industries, and the rest of the world has low-skill, labor-intensive industries and extraction of raw materials. This constantly reinforces the dominance of the core countries. This structure is unified by the division of labour. It is a world-economy rooted in a capitalist economy. For a time, certain countries have become the world hegemon; during the last few centuries, as the world-system has extended geographically and intensified economically, this status has passed from the Netherlands, to the United Kingdom and (most recently) to the United States.

A number of polities have declared independence and sought diplomatic recognition from the international community as sovereign states, but have not been universally recognised as such. These entities often have de facto control of their territory. A number of such entities have existed in the past.
There are two traditional theories used to indicate how a sovereign state comes into being. The declarative theory (codified in the 1933 Montevideo Convention) defines a state as a person in international law if it meets the following criteria: (Full article...) -

In world demographics, the world population is the total number of humans currently living. It was estimated by the United Nations to have exceeded eight billion in mid-November 2022. It took around 300,000 years of human prehistory and history for the human population to reach a billion and only 222 years more to reach 8 billion.
The human population has experienced continuous growth following the Great Famine of 1315–1317 and the end of the Black Death in 1350, when it was nearly 370,000,000. The highest global population growth rates, with increases of over 1.8% per year, occurred between 1955 and 1975, peaking at 2.1% between 1965 and 1970. The growth rate declined to 1.1% between 2015 and 2020 and is projected to decline further in the 21st century. The global population is still increasing, but there is significant uncertainty about its long-term trajectory due to changing fertility and mortality rates. The UN Department of Economics and Social Affairs projects between 9 and 10 billion people by 2050 and gives an 80% confidence interval of 10–12 billion by the end of the 21st century, with a growth rate by then of zero. Other demographers predict that the human population will begin to decline in the second half of the 21st century. (Full article...)

Dhaka (/ˈdɑːkə/ DAH-kə or /ˈdækə/ DAK-ə; Bengali: ঢাকা, romanized: Ḍhākā, IPA: [ˈɖʱaka]), formerly known as Dacca, is the capital and largest city of Bangladesh. It is the ninth-largest and seventh-most densely populated city in the world. Dhaka is a megacity, and has a population of 10.2 million residents as of 2022, and a population of over 22.4 million residents in Dhaka Metropolitan Area. It is widely considered to be the most densely populated built-up urban area in the world. Dhaka is the most important cultural, economic, and scientific hub of Eastern South Asia, as well as a major Muslim-majority city. Dhaka ranks third in South Asia and 39th in the world in terms of GDP. Lying on the Ganges Delta, it is bounded by the Buriganga, Turag, Dhaleshwari and Shitalakshya rivers. Dhaka is also the largest Bengali-speaking city in the world.
The area of Dhaka has been inhabited since the first millennium. An early modern city developed from the 17th century as a provincial capital and commercial centre of the Mughal Empire. Dhaka was the capital of a proto-industrialised Mughal Bengal for 75 years (1608–39 and 1660–1704). It was the hub of the muslin trade in Bengal and one of the most prosperous cities in the world. The Mughal city was named Jahangirnagar (The City of Jahangir) in honour of the erstwhile ruling emperor Jahangir. The city's wealthy Mughal elite included princes and the sons of Mughal emperors. The pre-colonial city's glory peaked in the 17th and 18th centuries when it was home to merchants from across Eurasia. The Port of Dhaka was a major trading post for both riverine and seaborne trade. The Mughals decorated the city with well-laid gardens, tombs, mosques, palaces, and forts. The city was once called the Venice of the East. (Full article...)Did you know - load new batch

Peru, officially the Republic of Peru, is a country in western South America. It is bordered in the north by Ecuador and Colombia, in the east by Brazil, in the southeast by Bolivia, in the south by Chile, and in the south and west by the Pacific Ocean. Peru is a megadiverse country with habitats ranging from the arid plains of the Pacific coastal region in the west to the peaks of the Andes mountains extending from the north to the southeast of the country to the tropical Amazon basin rainforest in the east with the Amazon River. Peru has a population of over 32 million, and its capital and largest city is Lima. At 1,285,216 km2 (496,225 sq mi), Peru is the 19th largest country in the world, and the third largest in South America.
Peruvian territory was home to several cultures during the ancient and medieval periods, and has one of the longest histories of civilization of any country, tracing its heritage back to the 10th millennium BCE. Notable pre-colonial cultures and civilizations include the Caral–Supe civilization (the earliest civilization in the Americas and considered one of the cradles of civilization), the Nazca culture, the Wari and Tiwanaku empires, the Kingdom of Cusco, and the Inca Empire, the largest known state in the pre-Columbian Americas. The Spanish Empire conquered the region in the 16th century and Charles V established a viceroyalty with the official name of the Kingdom of Peru that encompassed most of its South American territories, with its capital in Lima. Higher education started in the Americas with the official establishment of the National University of San Marcos in Lima in 1551. (Full article...)Related portals

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...) -

Svalbard is an Arctic wilderness archipelago comprising the northernmost part of Norway. There are twenty-nine protected natural areas, consisting of seven national parks, six nature reserves, fifteen bird sanctuaries and one geotope protected area. In addition, human traces dating from before 1946 are automatically protected. The protected areas make up 39,800 square kilometers (15,400 sq mi) or 65% of the land area, and 78,000 square kilometers (30,000 sq mi) or 86.5% of the territorial waters. The largest protected areas are Nordaust-Svalbard Nature Reserve and Søraust-Svalbard Nature Reserve, which cover most of the areas east of the main island of Spitsbergen, including the islands of Nordaustlandet, Edgeøya, Barentsøya, Kong Karls Land and Kvitøya. Six of the national parks are located on Spitsbergen. Ten of the bird sanctuaries and the Moffen Nature Reserve are located within national parks. Five of the bird sanctuaries are Ramsar sites and fourteen of the bird sanctuaries are islands. Svalbard is on Norway's tentative list for nomination as a UNESCO World Heritage Site.
The supreme responsibility for conservation lies with the Norwegian Ministry of the Environment, which has delegated the management to the Governor of Svalbard and the Norwegian Directorate for Nature Management. The foundation for conservation was established in the Svalbard Treaty of 1920, and has been further specified in the Svalbard Environmental Act of 2001. The first round of protection took force on 1 July 1973, when most of the current protected areas came into effect. This included the two large nature reserves and three of the national parks. Moffen Nature Reserve was established in 1983, followed by four national parks, three nature reserves and one geotope protection area between 2002 and 2005. (Full article...) -
