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 1Global change in broad sense refers to planetary-scale changes in the Earth system. It is most commonly used to encompass the variety of changes connected to the rapid increase in human activities which started around mid-20th century, i.e., the Great Acceleration. While the concept stems from research on the climate change, it is used to adopt a more holistic view of the observed changes. Global change refers to the changes of the Earth system, treated in its entirety with interacting physicochemical and biological components as well as the impact human societies have on the components and vice versa. Therefore, the changes are studied through means of Earth system science. (Full article...)

Image 2Superpower describes a state or supranational union that holds a dominant position characterized by the ability to exert influence or project power on a global scale. This is done through the combined means of economic, military, technological, political, and cultural strength as well as diplomatic and soft power influence. Traditionally, superpowers are preeminent among the great powers. While a great power state is capable of exerting its influence globally, superpowers are states so influential that no significant action can be taken by the global community without first considering the positions of the superpowers on the issue.
In 1944, during World War II, the term was first applied to the United States, the British Empire, and the Soviet Union. During the Cold War, the British Empire dissolved, leaving the United States and the Soviet Union to dominate world affairs. At the end of the Cold War and the dissolution of the Soviet Union in 1991, the United States became, and remains, the world's sole superpower, a position sometimes referred to as that of a "hyperpower". Since the late 2010s and into the 2020s, China has been described as a new superpower, as China poses "the most significant challenge of any nation-state in the world to the United States".

Earth's crust is its thick outer shell of rock, referring to less than one percent of the planet's radius and volume. It is the top component of the lithosphere, a division of Earth's layers that includes the crust and the upper part of the mantle. The lithosphere is broken into tectonic plates whose motion allows heat to escape the interior of Earth into space.
The crust lies on top of the mantle, a configuration that is stable because the upper mantle is made of peridotite and is therefore significantly denser than the crust. The boundary between the crust and mantle is conventionally placed at the Mohorovičić discontinuity, a boundary defined by a contrast in seismic velocity. (Full article...) -

The World as Will and Representation (WWR; German: Die Welt als Wille und Vorstellung, WWV), sometimes translated as The World as Will and Idea, is the central work of the German philosopher Arthur Schopenhauer. The first edition was published in late 1818, with the date 1819 on the title-page. A second, two-volume edition appeared in 1844: volume one was an edited version of the 1818 edition, while volume two consisted of commentary on the ideas expounded in volume one. A third expanded edition was published in 1859, the year prior to Schopenhauer's death. In 1948, an abridged version was edited by Thomas Mann.
In the summer of 1813, Schopenhauer submitted his doctoral dissertation—On the Fourfold Root of the Principle of Sufficient Reason—and was awarded a doctorate from the University of Jena. After spending the following winter in Weimar, he lived in Dresden and published his treatise On Vision and Colours in 1816. Schopenhauer spent the next several years working on his chief work, The World as Will and Representation. Schopenhauer asserted that the work is meant to convey a "single thought" from various perspectives. He develops his philosophy over four books covering epistemology, ontology, aesthetics, and ethics. Following these books is an appendix containing Schopenhauer's detailed Criticism of the Kantian Philosophy. (Full article...) -

The International Development Association (IDA) (French: Association internationale de développement) is a development finance institution which offers concessional loans and grants to the world's poorest developing countries. The IDA is a member of the World Bank Group and is headquartered in Washington, D.C. in the United States. It was established in 1960 to complement the existing International Bank for Reconstruction and Development by lending to developing countries which suffer from the lowest gross national income, from troubled creditworthiness, or from the lowest per capita income. Together, the International Development Association and International Bank for Reconstruction and Development are collectively generally known as the World Bank, as they follow the same executive leadership and operate with the same staff.
The association shares the World Bank's mission of reducing poverty and aims to provide affordable development financing to countries whose credit risk is so prohibitive that they cannot afford to borrow commercially or from the Bank's other programs. The IDA's stated aim is to assist the poorest nations in growing more quickly, equitably, and sustainably to reduce poverty. The IDA is the single largest provider of funds to economic and human development projects in the world's poorest nations. From 2000 to 2010, it financed projects which recruited and trained 3 million teachers, immunized 310 million children, funded $792 million in loans to 120,000 small and medium enterprises, built or restored 118,000 kilometers of paved roads, built or restored 1,600 bridges, and expanded access to improved water to 113 million people and improved sanitation facilities to 5.8 million people. The IDA has issued a total US$238 billion in loans and grants since its launch in 1960. Thirty-six of the association's borrowing countries have graduated from their eligibility for its concessional lending. However, nine of these countries have relapsed and have not re-graduated.

Image 6The cosmic egg, world egg or mundane egg is a mythological motif found in the cosmogonies of many cultures and civilizations, including in Proto-Indo-European mythology. Typically, there is an egg which, upon "hatching", either gives rise to the universe itself or gives rise to a primordial being who, in turn, creates the universe. The egg is sometimes lain on the primordial waters of the Earth. Typically, the upper half of the egg, or its outer shell, becomes the heaven (firmament) and the lower half, or the inner yolk, becomes the Earth. The motif likely stems from simple elements of an egg, including its ability to offer nourishment and give rise to new life, as is reflected by the Latin proverb omne vivum ex ovo ('all life comes from an egg').
The term "cosmic egg" is also used in the modern study of cosmology in the context of emergent Universe scenarios. (Full article...) -
Image 7A worldview or a world-view or Weltanschauung is the fundamental cognitive orientation of an individual or society encompassing the whole of the individual's or society's knowledge, culture, and point of view.

Armenia (/ɑːrˈmiːniə/ ⓘ ar-MEE-nee-ə), officially the Republic of Armenia, is a landlocked country in the Armenian Highlands of West Asia. It is a part of the Caucasus region and is bordered by Turkey to the west, Georgia to the north and Azerbaijan to the east, and Iran and the Azerbaijani exclave of Nakhchivan to the south. Yerevan is the capital, largest city and financial center.
Armenia is a unitary, multi-party, democratic nation-state with an ancient cultural heritage. The Armenian Highlands has been home to the Hayasa-Azzi, Shupria and Nairi. By at least 600 BC, an archaic form of Proto-Armenian, an Indo-European language, had diffused into Armenian Highlands. The first Armenian state of Urartu was established in 860 BC, and by the 6th century BC it was replaced by the Satrapy of Armenia. The Kingdom of Armenia reached its height under Tigranes the Great in the 1st century BC and in the year 301 became the first state in the world to adopt Christianity as its official religion. Armenia still recognises the Armenian Apostolic Church, the world's oldest national church, as the country's primary religious establishment. The ancient Armenian kingdom was split between the Byzantine and Sasanian Empires around the early 5th century. Under the Bagratuni dynasty, the Bagratid Kingdom of Armenia was restored in the 9th century before falling in 1045. Cilician Armenia, an Armenian principality and later a kingdom, was located on the coast of the Mediterranean Sea between the 11th and 14th centuries.

Protected areas of the United Kingdom are areas in the United Kingdom which need and /or receive protection because of their environmental, historical or cultural value to the nation. Methods and aims of protection vary depending on the nature and importance of the resource. Protection operates at local, regional, national and international levels, and may be backed by legislation and international treaty, or less formally by planning policy.
Within the United Kingdom, different approaches are taken to some forms of protection within the constituent countries of England, Scotland, Wales and Northern Ireland, while other forms of protection are more consistent across the UK. Protected areas can be divided according to the type of resource which each seeks to protect. Primarily, these are: scenic or landscape value; biodiversity value (species and habitats); geodiversity value (relating to geology and geomorphology); and cultural or historic value. Several types of protected areas are focused on more than one of these areas. (Full article...) -
