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 Space Age is a period encompassing the activities related to the space race, space exploration, space technology, and the cultural developments influenced by these events, beginning with the launch of Sputnik 1 on October 4, 1957, and continuing to the present.
This period is characterized by changes in emphasis on particular areas of space exploration and applications. Initially, the United States and the Soviet Union invested unprecedented amounts of resources in breaking records and being first to meet milestones in crewed and uncrewed exploration. The United States established the National Aeronautics and Space Administration (NASA) and the USSR established the Kosmicheskaya programma SSSR to meet these goals. This period of competition gave way to cooperation between those nations and emphasis on scientific research and commercial applications of space-based technology. (Full article...) -

A pandemic (/pænˈdɛmɪk/ pan-DEM-ik) is an epidemic of an infectious disease that has spread across a large region, for instance multiple continents or worldwide, affecting a substantial number of individuals. Widespread endemic diseases with a stable number of infected individuals such as recurrences of seasonal influenza are generally excluded as they occur simultaneously in large regions of the globe rather than being spread worldwide.
Throughout human history, there have been a number of pandemics of diseases such as smallpox. The Black Death, caused by the Plague, wiped out up to half of the population of Europe in the 14th century. The term pandemic had not been used then, but was used for later epidemics, including the 1918 H1N1 influenza A pandemic—more commonly known as the Spanish flu—which is the deadliest pandemic in history. The most recent pandemics include the HIV/AIDS pandemic, the 2009 swine flu pandemic and the COVID-19 pandemic. Almost all these diseases still circulate among humans though their impact now is often far less. (Full article...) -

The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radio navigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems (GNSS) that provide geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. It does not require the user to transmit any data, and operates independently of any telephonic or Internet reception, though these technologies can enhance the usefulness of the GPS positioning information. It provides critical positioning capabilities to military, civil, and commercial users around the world. Although the United States government created, controls and maintains the GPS system, it is freely accessible to anyone with a GPS receiver. (Full article...) -

Ancient history is a time period from the beginning of writing and recorded human history through late antiquity. The span of recorded history is roughly 5,000 years, beginning with the development of Sumerian cuneiform script and continuing until the expansion of Islam in late antiquity. Ancient history covers all continents inhabited by humans in the period 3000 BC – AD 750. The three-age system periodizes ancient history into the Stone Age, the Bronze Age, and the Iron Age, with recorded history generally considered to begin with the Bronze Age. The start and end of the three ages vary between world regions. In many regions the Bronze Age is generally considered to begin a few centuries prior to 3000 BC, while the end of the Iron Age varies from the early first millennium BC in some regions to the late first millennium AD in others.
During the time period of ancient history, the world population was already exponentially increasing due to the Neolithic Revolution, which was in full progress. While in 10,000 BC, the world population stood at 2 million, it rose to 45 million by 3,000 BC. By the Iron Age in 1000 BC, the population had risen to 72 million. By the end of the ancient period in AD 500, the world population is thought to have stood at 209 million. In 10,500 years, the world population increased by 100 times. (Full article...) -

The United Nations Educational, Scientific and Cultural Organization (UNESCO) is a specialized agency of the United Nations (UN) with the aim of promoting world peace and security through international cooperation in education, arts, sciences and culture. It has 194 member states and 12 associate members, as well as partners in the non-governmental, intergovernmental and private sector. Headquartered in Paris, France, UNESCO has 53 regional field offices and 199 national commissions.
UNESCO was founded in 1945 as the successor to the League of Nations' International Committee on Intellectual Cooperation. Its constitution establishes the agency's goals, governing structure, and operating framework. UNESCO's founding mission, which was shaped by the events of World War II, is to advance peace, sustainable development and human rights by facilitating collaboration and dialogue among nations. It pursues this objective through five major programme areas: education, natural sciences, social/human sciences, culture and communication/information. UNESCO sponsors projects that improve literacy, provide technical training and education, advance science, protect independent media and press freedom, preserve regional and cultural history, and promote cultural diversity.

The Holocene extinction, or Anthropocene extinction, is the ongoing extinction event caused by humans during the Holocene epoch. These extinctions span numerous families of plants and animals, including mammals, birds, reptiles, amphibians, fish, and invertebrates, and affecting not just terrestrial species but also large sectors of marine life. With widespread degradation of biodiversity hotspots, such as coral reefs and rainforests, as well as other areas, the vast majority of these extinctions are thought to be undocumented, as the species are undiscovered at the time of their extinction, which goes unrecorded. The current rate of extinction of species is estimated at 100 to 1,000 times higher than natural background extinction rates and is increasing. During the past 100–200 years, biodiversity loss and species extinction have accelerated, to the point that most conservation biologists now believe that human activity has either produced a period of mass extinction, or is on the cusp of doing so. As such, after the "Big Five" mass extinctions, the Holocene extinction event has also been referred to as the sixth mass extinction or sixth extinction; given the recent recognition of the Capitanian mass extinction, the term seventh mass extinction has also been proposed for the Holocene extinction event.
The Holocene extinction follows the extinction of many large (megafaunal) animals during the preceding Late Pleistocene. Some of these extinctions were likely in part due to human hunting pressure. The most popular theory is that human overhunting of species added to existing stress conditions as the Holocene extinction coincides with human colonization of many new areas around the world. Although there is debate regarding how much human predation and habitat loss affected their decline, certain population declines have been directly correlated with the onset of human activity, such as the extinction events of New Zealand, Madagascar, and Hawaii. Aside from humans, climate change may have been a driving factor in the megafaunal extinctions, especially at the end of the Pleistocene. (Full article...) -
Image 7The list of climate change controversies (or list of global warming controversies) concerns past or present public debates over certain aspects of climate change: whether it is occurring (climate change deniers dispute this), how much has occurred in modern times, what has caused it, what its effects will be, whether action should be taken to curb it now or later, and so forth. In the scientific literature, there is a very strong consensus that global surface temperatures have increased in recent decades and that the trend is caused by human-induced emissions of greenhouse gases.
The controversies are, by now, mostly political rather than scientific: there is a scientific consensus that global warming is happening and is caused by human activity. Public debates that also reflect scientific debate include estimates of how responsive the climate system might be to any given level of greenhouse gases (climate sensitivity). Disputes over the key scientific facts of global warming are more prevalent in the media than in the scientific literature, where such issues are treated as resolved, and such disputes are more prevalent in the United States and Australia than globally.

Hangzhou is the capital and most populous city of Zhejiang, China. It is located in the northeastern part of the province, sitting at the head of Hangzhou Bay, which separates Shanghai and Ningbo. Hangzhou grew to prominence as the southern terminus of the Grand Canal and has been one of China's most renowned and prosperous cities for much of the last millennium. It is a major economic and e-commerce hub within China, and the second biggest city in the Yangtze Delta after Shanghai. Hangzhou is classified as a sub-provincial city and forms the core of the Hangzhou metropolitan area, the fourth-largest in China after Guangzhou-Shenzhen Pearl River agglomeration, Shanghai-Suzhou-Wuxi-Changzhou conurbation and Beijing. As of 2022, the Hangzhou metropolitan area was estimated to produce a gross metropolitan product (nominal) of 4 trillion yuan (US$590 billion), making it larger than the economy of Sweden. As of the 2020 Chinese census, it had a total population of 11,936,010 inhabitants. However, its metropolitan area, populated by 13.035 million people over an area of 8,107.9 km2 (3,130.5 sq mi), consists of all urban districts in Hangzhou and 3 urban districts of the city of Shaoxing.
Hangzhou has been repeatedly rated as the best commercial city in mainland China by Forbes and the Chinese city with the highest growth potential by the Economist Intelligence Unit. A study conducted by PwC and China Development Research Foundation ranked Hangzhou first among "Chinese Cities of Opportunity". According to the Globalization and World Cities Research Network (GaWC), the city is classified as a Beta (global second-tier) city, together with Chongqing, Nanjing and Tianjin in China. Hangzhou is also one of the world's top 100 financial centers, according to the Global Financial Centres Index. It boasts the eighth largest GDP among cities in mainland China with a GDP of around 1.8 trillion RMB ($280 billion). Home to the headquarters of large global tech companies such as Alibaba Group, Ant Group, and NetEase, Hangzhou is known for attracting professionals and entrepreneurs who work in information technology. , Hangzhou has the tenth-most Fortune Global 500 headquarters of any city in the world and the fourth-most in China – after Beijing, Shanghai and Shenzhen – within its city limits. According to the 2020 Hurun Global Rich List, Hangzhou ranks 11th in the world and 6th in China (after Beijing, Shanghai, Hong Kong, Shenzhen and Guangzhou) in the number of resident billionaires.
