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...)

Image 1"World music" is an English phrase for styles of music from non-Western countries, including quasi-traditional, intercultural, and traditional music. World music's broad nature and elasticity as a musical category pose obstacles to a universal definition, but its ethic of interest in the culturally exotic is encapsulated in Roots magazine's description of the genre as "local music from out there".
This music that does not follow "North American or British pop and folk traditions" was given the term "world music" by music industries in Europe and North America. The term was popularized in the 1980s as a marketing category for non-Western traditional music. It has grown to include subgenres such as ethnic fusion (Clannad, Ry Cooder, Enya, etc.) and worldbeat. (Full article...) -
Image 2Globalism has multiple meanings. In political science, it is used to describe "attempts to understand all the interconnections of the modern world—and to highlight patterns that underlie (and explain) them". While primarily associated with world-systems, it can be used to describe other global trends. The concept of globalism is also classically used to focus on the ideologies of globalization (the subjective meanings) instead of its processes (the objective practices); in this sense, "globalism" is to globalization what "nationalism" is to nationality.
The term is now frequently used as a pejorative by far-right movements and conspiracy theorists, as in the New World Order conspiracy theory; it is associated with antisemitism, as antisemites frequently appropriate the term globalist to refer to Jews. (Full article...) -
Image 3A world language (sometimes global language, rarely international language) is a language that is geographically widespread and makes it possible for members of different language communities to communicate. The term may also be used to refer to constructed international auxiliary languages such as Esperanto.
English is the foremost, and by some accounts the only, world language. Other possible world languages are: Arabic, French, Russian, and Spanish, although there is no clear academic consensus on the subject. Some authors consider Latin to have formerly been a world language. (Full article...) -

The United Nations (UN) is a diplomatic and political international organization whose stated purposes are to maintain international peace and security, develop friendly relations among nations, achieve international cooperation, and serve as a centre for harmonizing the actions of nations. It is the world's largest international organization. The UN is headquartered in New York City (in the United States, but with certain extraterritorial privileges), and the UN has other offices in Geneva, Nairobi, Vienna, and The Hague, where the International Court of Justice is headquartered at the Peace Palace.
The UN was established after World War II with the aim of preventing future world wars, and succeeded the League of Nations, which was characterized as ineffective. On 25 April 1945, 50 nations met in San Francisco, California for a conference and started drafting the UN Charter, which was adopted on 25 June 1945. The charter took effect on 24 October 1945, when the UN began operations. The UN's objectives, as defined by its charter, include maintaining international peace and security, protecting human rights, delivering humanitarian aid, promoting sustainable development, and upholding international law. At its founding, the UN had 51 member states; , it has 193 – almost all of the world's sovereign states. (Full article...) -

The Eastern world, also known as the East or historically the Orient, is an umbrella term for various cultures or social structures, nations and philosophical systems, which vary depending on the context. It most often includes Asia, the Mediterranean region and the Arab world, specifically in historical (pre-modern) contexts, and in modern times in the context of Orientalism. The Eastern world is often seen as a counterpart to the Western world.
The various regions included in the term are varied, hard to generalize, and do not have a single shared common heritage. Although the various parts of the Eastern world share many common threads, most notably being in the "Global South", they have never historically defined themselves collectively. The term originally had a literal geographic meaning, referring to the eastern part of the Old World, contrasting the cultures and civilizations of Asia with those of Europe (or the Western world). Traditionally, this includes Central Asia, East Asia, South Asia, Southeast Asia and West Asia. (Full article...) -
Image 6The history of science covers the development of science from ancient times to the present. It encompasses all three major branches of science: natural, social, and formal. Protoscience, early sciences, and natural philosophies such as alchemy and astrology during the Bronze Age, Iron Age, classical antiquity, and the Middle Ages declined during the early modern period after the establishment of formal disciplines of science in the Age of Enlightenment.
Science's earliest roots can be traced to Ancient Egypt and Mesopotamia around 3000 to 1200 BCE. These civilizations' contributions to mathematics, astronomy, and medicine influenced later Greek natural philosophy of classical antiquity, wherein formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Latin-speaking Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but continued to thrive in the Greek-speaking Byzantine Empire. Aided by translations of Greek texts, the Hellenistic worldview was preserved and absorbed into the Arabic-speaking Muslim world during the Islamic Golden Age. The recovery and assimilation of Greek works and Islamic inquiries into Western Europe from the 10th to 13th century revived the learning of natural philosophy in the West. Traditions of early science were also developed in ancient India and separately in ancient China, the Chinese model having influenced Vietnam, Korea and Japan before Western exploration. Among the Pre-Columbian peoples of Mesoamerica, the Zapotec civilization established their first known traditions of astronomy and mathematics for producing calendars, followed by other civilizations such as the Maya.

In world history, post-classical history refers to the period from about 500 CE to 1500 CE, roughly corresponding to the European Middle Ages. The period is characterized by the expansion of civilizations geographically and the development of trade networks between civilizations. This period is also called the medieval era, post-antiquity era, post-ancient era, pre-modernity era, or pre-modern era.
In Asia, the spread of Islam created a series of caliphates and inaugurated the Islamic Golden Age, leading to advances in science in the medieval Islamic world and trade among the Asian, African, and European continents. East Asia experienced the full establishment of the power of Imperial China, which established several prosperous dynasties influencing Japan, Korea, and Vietnam. Religions such as Buddhism and neo-Confucianism spread in the region. Gunpowder was developed in China during the post-classical era. The Mongol Empire connected Europe and Asia, creating safe trade and stability between the two regions. In total, the population of the world doubled in the time period, from approximately 210 million in 500 CE to 461 million in 1500 CE. The population generally grew steadily throughout the period but endured some incidental declines due to events including the Plague of Justinian, the Mongol invasions, and the Black Death.

Lima (/ˈliːmə/ LEE-mə; locally [ˈlima]), founded in 1535 as the Ciudad de los Reyes (locally [sjuˈðað ðe los ˈreʝes], Spanish for "City of Kings"), is the capital and largest city of Peru. It is located in the valleys of the Chillón, Rímac and Lurín Rivers, in the desert zone of the central coastal part of the country, overlooking the Pacific Ocean. The city is considered the political, cultural, financial and commercial center of Peru. Due to its geostrategic importance, the Globalization and World Cities Research Network has categorized it as a "beta" tier city. Jurisdictionally, the metropolis extends mainly within the province of Lima and in a smaller portion, to the west, within the Constitutional Province of Callao, where the seaport and the Jorge Chávez Airport are located. Both provinces have regional autonomy since 2002.
The 2023 census projection indicates that the city of Lima has an estimated population of 10,092,000 inhabitants, making it the most populated city in the country, and the second most populous in the Americas after São Paulo. Together with the seaside city of Callao, it forms a contiguous urban area known as the Lima Metropolitan Area, which encompasses a total of 10,151,200 inhabitants. When considering the constitutional province of Callao, the total agglomeration reaches a population of 11,342,100 inhabitants, one of the thirty most populated urban agglomerations in the world.

Senegal, officially the Republic of Senegal, is the westernmost country in continental Africa, situated on the Atlantic Ocean coastline. Senegal is bordered by Mauritania to the north, Mali to the east, Guinea to the southeast and Guinea-Bissau to the southwest. Senegal nearly surrounds The Gambia, a country occupying a narrow sliver of land along the banks of the Gambia River, which separates Senegal's southern region of Casamance from the rest of the country. Senegal also shares a maritime border with Cape Verde. Senegal's economic and political capital is Dakar.
Senegal is the westernmost country in the mainland of the Old World, or Afro-Eurasia. It owes its name to the Senegal River, which borders it to the east and north. The climate is typically Sahelian, though there is a rainy season. Senegal covers a land area of almost 197,000 square kilometres (76,000 sq mi) and has a population of around 18 million.0 The state is a unitary presidential republic; since the country's foundation in 1960, it has been recognized as one of the most stable countries on the African continent. On the 2023 V-Dem Democracy Indices, Senegal is ranked 52nd in electoral democracy worldwide and 4th in electoral democracy in Africa.

Image 1This is a list of the nationally designated protected areas of China. There are many forms of protected areas in China. Based on their relative importance, each type of protected area can be further graded into two to three levels (national, provincial and prefectural/county level). Nevertheless, the highest rank for "pocket nature preserve" (social and mass-based), "no-hunting area", "no-fishing area", "no-logging area", "wild medicinal material resources conservation area", "crop germplasm resources conservation area", "forest tree germplasm resources conservation area" or "source water protection area" is practically restricted to provincial level. The local government at county level is also responsible for the delimitation and declaration of "basic farmland protection area" and "basic grassland".
Take note that many protected areas in China have multiple official designations, and the statutory boundaries of these multi-designated PAs may be identical or may vary one from the other. For instance, the boundaries of Huangshan NSHA coincide with those of the Huangshan NGP, whereas Fujian province's Wuyi Mountains NNR, NSHA and NFP are adjacent to each other. In Heilongjiang, 27,642.14 hectares out of 115,340.27 hectares of Huzhong NFP are intersected with the experiment zone of Huzhong NNR. (Full article...) -
