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...)

Image 1Portrait of Isaac Newton by Godfrey Kneller, 1689
The Scientific Revolution of the 16th and 17th centuries in Europe was an irreversible break with the natural philosophy that had preceded it, fundamentally changing how the natural world was investigated and understood. The New Science that emerged departed from previous Greek conceptions and traditions, was more mechanistic in its worldview and more integrated with mathematics, and was focused on the acquisition and interpretation of new evidence.
The Scientific Revolution is a convenient boundary between ancient thought and modern science. While the period is frequently said to have begun in 1543 with the printings of De humani corporis fabrica (On the Workings of the Human Body) by Andreas Vesalius and De Revolutionibus (On the Revolutions of the Heavenly Spheres) by Nicolaus Copernicus, the SN 1572 supernova has also been suggested as its beginning. The period culminated with the publication of the Philosophiæ Naturalis Principia Mathematica in 1687 by Isaac Newton. (Full article...) -

World GDP per capita between 1500 and 2003
The world economy or global economy is the economy of all humans in the world, referring to the global economic system, which includes all economic activities conducted both within and between nations, including production, consumption, economic management, work in general, financial transactions and trade of goods and services. In some contexts, the two terms are distinct: the "international" or "global economy" is measured separately and distinguished from national economies, while the "world economy" is simply an aggregate of the separate countries' measurements. Beyond the minimum standard concerning value in production, use and exchange, the definitions, representations, models and valuations of the world economy vary widely. It is inseparable from the geography and ecology of planet Earth.
It is common to limit questions of the world economy exclusively to human economic activity, and the world economy is typically judged in monetary terms, even in cases in which there is no efficient market to help valuate certain goods or services, or in cases in which a lack of independent research, genuine data or government cooperation makes calculating figures difficult. Typical examples are illegal drugs and other black market goods, which by any standard are a part of the world economy, but for which there is, by definition, no legal market of any kind.

Image 3The Internet originated in the efforts of scientists and engineers to build and interconnect computer networks. The Internet Protocol Suite, the set of rules used to communicate between networks and devices on the Internet, arose from research and development in the United States and involved international collaboration, particularly with researchers in the United Kingdom and France.
Computer science was an emerging discipline in the late 1950s that began to consider time-sharing between computer users, and later, the possibility of achieving this over wide area networks. J. C. R. Licklider articulated the idea of a universal network at the Information Processing Techniques Office (IPTO) of the United States Department of Defense (DoD) Advanced Research Projects Agency (ARPA). Independently, Paul Baran at the RAND Corporation proposed a distributed network based on data in message blocks in the early 1960s, and Donald Davies conceived of packet switching in 1965 at the National Physical Laboratory (NPL), proposing a national commercial data network in the United Kingdom.

The World Health Organization in Geneva, Switzerland
Global health is the health of populations in a worldwide context; it has been defined as "the area of study, research, and practice that places a priority on improving health and achieving equity in health for all people worldwide". Problems that transcend national borders or have a global political and economic impact are often emphasized. Thus, global health is about worldwide health improvement (including mental health), reduction of disparities, and protection against global threats that disregard national borders, including the most common causes of human death and years of life lost from a global perspective.
Global health is not to be confused with international health, which is defined as the branch of public health focusing on developing nations and foreign aid efforts by industrialized countries. (Full article...) -

Sand dunes in the Rub' al Khali ("Empty quarter") of Arabia
A desert is a landscape where little precipitation occurs and, consequently, living conditions create unique biomes and ecosystems. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid. This includes much of the polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location.
Deserts are formed by weathering processes as large variations in temperature between day and night strain the rocks, which consequently break into pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting fragments and rubble strewn over the desert floor are further eroded by the wind. This picks up particles of sand and dust, which can remain airborne for extended periods – sometimes causing the formation of sand storms or dust storms. Wind-blown sand grains striking any solid object in their path can abrade the surface. Rocks are smoothed down, and the wind sorts sand into uniform deposits. The grains end up as level sheets of sand or are piled high in billowing dunes. Other deserts are flat, stony plains where all the fine material has been blown away and the surface consists of a mosaic of smooth stones, often forming desert pavements, and little further erosion occurs. Other desert features include rock outcrops, exposed bedrock and clays once deposited by flowing water. Temporary lakes may form and salt pans may be left when waters evaporate. There may be underground water sources in the form of springs and seepages from aquifers. Where these are found, oases can occur. (Full article...) -

The International Monetary Fund (IMF) is an international financial institution and a specialized agency of the United Nations, headquartered in Washington, D.C. It consists of 191 member countries, and its stated mission is "working to foster global monetary cooperation, secure financial stability, facilitate international trade, promote high employment and sustainable economic growth, and reduce poverty around the world." The IMF acts as a lender of last resort to its members experiencing actual or potential balance of payments crises.
Established in July 1944 at the Bretton Woods Conference based on the ideas of Harry Dexter White and John Maynard Keynes, the IMF came into formal existence in 1945 with 29 member countries and the goal of reconstructing the international monetary system. For its first three decades, the IMF oversaw the Bretton Woods system of fixed exchange rate arrangements. Following the collapse of this system in 1971, the Fund's role shifted to managing balance-of-payments difficulties and international financial crises, becoming a key institution in the era of globalization.

Among the various cradles of civilization is Ancient Egypt. Pictured are the Giza Pyramids.
A cradle of civilization is a location and a culture where civilization was developed independently of other civilizations in other locations. A civilization is any complex society characterized by the development of the state, social stratification, urbanization, and symbolic systems of communication beyond signed or spoken languages (namely, writing systems and graphic arts).
Scholars generally acknowledge six cradles of civilization: Mesopotamia, Ancient Egypt, Ancient India and Ancient China are believed to be the earliest in Afro-Eurasia, while the Caral–Supe civilization of coastal Peru and the Olmec civilization of Mexico are believed to be the earliest in the Americas. All of the cradles of civilization depended upon agriculture for sustenance (except possibly Caral–Supe which may have depended initially on marine resources). All depended upon farmers producing an agricultural surplus to support the centralized government, political leaders, religious leaders, and public works of the urban centers of the early civilizations.

Guangzhou is the capital and largest city of the Guangdong province of southern China. Located on the Pearl River, about 120 kilometres (75 mi) northwest of Hong Kong and 145 kilometres (90 mi) north of Macau, Guangzhou has a history of over 2,200 years and was a major terminus of the Silk Road.
The port of Guangzhou serves as transportation hub. Guangzhou is also one of China's three largest cities. For a long time, it was the only Chinese port accessible to most foreign traders. Guangzhou was captured by the British during the First Opium War and no longer enjoyed a monopoly after the war. Consequently it lost trade to other ports such as Hong Kong and Shanghai, but continued to serve as a major entrepôt. Following the Second Battle of Chuenpi in 1841, the Treaty of Nanking was signed between Sir Robert Peel on behalf of Queen Victoria and Lin Zexu on behalf of Emperor Xuanzong and ceded Hong Kong to the United Kingdom on 26 January 1841 after the agreement of the Convention of Chuenpi.

Lithuania, officially the Republic of Lithuania, is a country in the Baltic region of Europe. It is one of three Baltic states and lies on the eastern shore of the Baltic Sea, bordered by Latvia to the north, Belarus to the east and south, Poland to the south, and the Russian semi-exclave of Kaliningrad Oblast to the southwest, with a maritime border with Sweden to the west. Lithuania covers an area of 65,300 km2 (25,200 sq mi), and has a population of 2.9 million. Its capital and largest city is Vilnius; other major cities include Kaunas, Klaipėda, Šiauliai and Panevėžys. Lithuanians are the titular nation, belong to the ethnolinguistic group of Balts, and speak Lithuanian.
For millennia, the southeastern shores of the Baltic Sea were inhabited by various Baltic tribes. In the 1230s, Lithuanian lands were united for the first time by Mindaugas, who formed the Kingdom of Lithuania on 6 July 1253. Subsequent expansion and consolidation resulted in the Grand Duchy of Lithuania, which by the 14th century was the largest country in Europe. In 1386, the grand duchy entered into a de facto personal union with the Crown of the Kingdom of Poland. The two realms were united into the Polish-Lithuanian Commonwealth in 1569, forming one of the largest and most prosperous states in Europe. The commonwealth lasted more than two centuries, until neighbouring countries gradually dismantled it between 1772 and 1795, with the Russian Empire annexing most of Lithuania's territory.
