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...)

Chart of the world's gross domestic product over the last two millennia
The global financial system is the worldwide framework of legal agreements, institutions, and both formal and informal economic action that together facilitate international flows of financial capital for purposes of investment and trade financing. Since emerging in the late 19th century during the first modern wave of economic globalization, its evolution is marked by the establishment of central banks, multilateral treaties, and intergovernmental organizations aimed at improving the transparency, regulation, and effectiveness of international markets. In the late 1800s, world migration and communication technology facilitated unprecedented growth in international trade and investment. At the onset of World War I, trade contracted as foreign exchange markets became paralyzed by money market illiquidity. Countries sought to defend against external shocks with protectionist policies and trade virtually halted by 1933, worsening the effects of the global Great Depression until a series of reciprocal trade agreements slowly reduced tariffs worldwide. Efforts to revamp the international monetary system after World War II improved exchange rate stability, fostering record growth in global finance.
A series of currency devaluations and oil crises in the 1970s led most countries to float their currencies. The world economy became increasingly financially integrated in the 1980s and 1990s due to capital account liberalization and financial deregulation. A series of financial crises in Europe, Asia, and Latin America followed with contagious effects due to greater exposure to volatile capital flows. The global financial crisis, which originated in the United States in 2007, quickly propagated among other nations and is recognized as the catalyst for the worldwide Great Recession. A market adjustment to Greece's noncompliance with its monetary union in 2009 ignited a sovereign debt crisis among European nations known as the Eurozone crisis. The history of international finance shows a U-shaped pattern in international capital flows: high prior to 1914 and after 1989, but lower in between. The volatility of capital flows has been greater since the 1970s than in previous periods. (Full article...) -

Human symbolic expression developed as prehistoric humans reached behavioral modernity.
Culture (/ˈkʌltʃər/ KUL-chər) is a concept that encompasses the social behavior, institutions, and norms found in human societies, as well as the knowledge, beliefs, arts, laws, customs, capabilities, and habits of the individuals in these groups. Culture is often originated from or attributed to a specific region or location.
Humans acquire culture through the learning processes of enculturation and socialization, which is shown by the diversity of cultures across societies. (Full article...) -
Image 3Proto-globalization or early modern globalization is a period of the history of globalization roughly spanning the years between 1500 and 1800, following the period of archaic globalization. First introduced by historians A. G. Hopkins and Christopher Bayly, the term describes the phase of increasing trade links and cultural exchange that characterized the period immediately preceding the advent of so-called "modern globalization" in the 19th century.
Proto-globalization distinguished itself from modern globalization on the basis of expansionism, the method of managing global trade, and the level of information exchange. The period is marked by the shift of hegemony to Western Europe, the rise of larger-scale conflicts between powerful nations such as the Thirty Years' War, and demand for commodities, most particularly slaves. The triangular trade made it possible for Europe to take advantage of resources within the western hemisphere. The transfer of plant and animal crops and epidemic diseases associated with Alfred Crosby's concept of the Columbian exchange also played a central role in this process. Proto-globalization trade and communications involved a vast group including European, Middle Eastern, Indian, Southeast Asian, and Chinese merchants, particularly in the Indian Ocean region.

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 living and working 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 so on 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 be by 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 5The Global Industry Classification Standard (GICS) is an industry taxonomy developed in 1999 by MSCI and Standard & Poor's (S&P) for use by the global financial community. The GICS structure consists of 11 sectors, 25 industry groups, 74 industries and 163 sub-industries into which S&P has categorized all major public companies. The system is similar to ICB (Industry Classification Benchmark), a classification structure maintained by FTSE Group.
GICS is used as a basis for S&P and MSCI financial market indexes in which each company is assigned to a sub-industry, and to an industry, industry group, and sector, by its principal business activity. "GICS" is a registered trademark of McGraw Hill Financial and MSCI Inc. (Full article...) -

The aircraft shown here, Chicago, led the first round the world flight in 1924.
The first aerial circumnavigation of the world was completed in 1924 by four aviators from an eight-man team of the United States Army Air Service, the precursor of the United States Air Force. The 175-day journey covered over 26,345 miles (42,398 km). The team generally traveled east to west, around the northern-Pacific Rim, through to South Asia and Europe and back to the United States. Airmen Lowell H. Smith and Leslie P. Arnold, and Erik H. Nelson and John Harding Jr. made the trip in two single-engined open-cockpit Douglas World Cruisers (DWC) configured as floatplanes for most of the journey. Four more flyers in two additional DWC began the journey but their aircraft crashed or were forced down. All airmen survived. They were all awarded the Mackay Trophy aviation award for 1924.

Old Moore's Almanack is an astrological almanac which has been published in Britain since 1697.
An almanac (also spelled almanack and almanach) is a regularly published listing of a set of current information about one or multiple subjects. It includes information like weather forecasts, farmers' planting dates, tide tables, and other tabular data often arranged according to the calendar. Celestial figures and various statistics are found in almanacs, such as the rising and setting times of the Sun and Moon, dates of eclipses, hours of high and low tides, and religious festivals. The set of events noted in an almanac may be tailored for a specific group of readers, such as farmers, sailors, or astronomers. (Full article...)

Nagoya (名古屋市, Nagoya-shi, [naꜜɡoja] ⓘ) is the largest city in the Chūbu region, the fourth-most populous city proper with a population of 2.3 million in 2020, and the principal city of the Chūkyō metropolitan area, which is the third-most populous metropolitan area in Japan with a population of 10.11 million. Located on the Pacific coast in central Honshu, it is the capital and most populous city of Aichi Prefecture, with the Port of Nagoya being Japan's largest seaport.
In 1610, the warlord Tokugawa Ieyasu, a retainer of Oda Nobunaga, moved the capital of Owari Province from Kiyosu to Nagoya. This period saw the renovation of Nagoya Castle. The arrival of the 20th century brought a convergence of economic factors that fueled rapid growth in Nagoya, during the Meiji Restoration, and became a major industrial hub for Japan. The traditional manufactures of timepieces, bicycles, and sewing machines were followed by the production of special steels, ceramic, chemicals, oil, and petrochemicals, as the area's automobile, aviation, and shipbuilding industries flourished. These factors made the city a target for US air raids during World War II. (Full article...)Did you know - load new batch

Cape Verde (/ˈvɜːrd(i)/ ⓘ, VURD or VUR-dee) or Cabo Verde (/ˌkɑːboʊ ˈvɜːrdeɪ/ ⓘ, /ˌkæb-/ KA(H)B-oh VUR-day; Portuguese: [ˈkaβu ˈveɾðɨ]), officially the Republic of Cabo Verde, is an archipelago and island country of West Africa in the central Atlantic Ocean, consisting of ten volcanic islands with a combined land area of about 4,033 square kilometres (1,557 sq mi). These islands lie between 600 and 850 kilometres (320 and 460 nautical miles) west of Cap-Vert, the westernmost point of continental Africa. The Cape Verde islands form part of the Macaronesia ecoregion, along with the Azores, the Canary Islands, Madeira and the Savage Isles.
The Cape Verde archipelago was uninhabited until the 15th century, when Portuguese explorers discovered and colonized the islands, thus establishing the first European settlement in the tropics. Because the Cape Verde islands were conveniently located to play a role in the Atlantic slave trade, Cape Verde became economically prosperous during the 16th and 17th centuries, attracting merchants, privateers, and pirates. It declined economically in the 19th century after the suppression of the Atlantic slave trade by the British Empire, and many of its inhabitants emigrated during that period. However, Cape Verde gradually recovered economically by becoming an important commercial center and useful stopover point along major shipping routes. Cape Verde became independent in 1975.

Image 5Protected areas of Tasmania consist of protected areas located within Tasmania and its immediate onshore waters, including Macquarie Island. It includes areas of crown land (withheld land) managed by Tasmanian Government agencies as well as private reserves. As of 2016, 52% of Tasmania's land area has some form of reservation classification, the majority is managed by the Tasmania Parks & Wildlife Service (about 42% of total Tasmanian land area). Marine protected areas cover about 7.9% of state waters.
Within each classification of reserve there may be a variation of IUCN categories Australia is a signatory to the Convention of Biological Diversity and as such has obligations to report the status of its National Reserve System.IUCN provides on its website a prescription for activities consistent with the categorisation system. Changes made to the Nature Conservation Act 2002 in 2014 permit timber harvesting. These changes made in addition to the already established right to access minerals means that many of the IUCN categorisations assigned to individual reserves in Tasmania are no longer fit for purpose. In addition many reserves have had their reserve status downgraded from a class excluding timber harvesting and mineral extraction to ones where these activities are now permitted. This mis-application of the IUCN protected area categories needs to be remedied or the reserves protected land class under the Nature Conservation Act 2002 should be adjusted to reflect its currently assigned IUCN category.
