Geographical Centre Of Earth
The geographical center of Earth is the geometric center of all land surfaces on Earth. Geometrically defined it is the Centroid of all land surfaces within the two dimensions of the Geoid surface which approximates the Earth's outer shape. The term ''center of minimum distance'' specifies the concept more precisely as the domain is the sphere surface without boundary and not the sphere as three-dimensional body. Explained in a different way, it is the location on the surface of Earth where the sum of distances to all locations on land is the smallest. If you had an airplane with an infinite energy resource and fly from one start location on Earth to one location on a land surface somewhere on Earth and back again and repeat that from the same start location to all possible destination locations, the starting locations where the total travel distance sums up as the smallest, marks the geographical center of Earth. Its distance definition follows the shortest path on the surface ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Of The Center Of The Universe
The center of the Universe is a concept that lacks a coherent definition in modern astronomy; according to standard cosmological theories on the shape of the universe, it has no center. Historically, different people have suggested various locations as the center of the Universe. Many mythological cosmologies included an ''axis mundi'', the central axis of a flat Earth that connects the Earth, heavens, and other realms together. In the 4th century BC Greece, philosophers developed the geocentric model, based on astronomical observation; this model proposed that the center of the Universe lies at the center of a spherical, stationary Earth, around which the Sun, Moon, planets, and stars rotate. With the development of the heliocentric model by Nicolaus Copernicus in the 16th century, the Sun was believed to be the center of the Universe, with the planets (including Earth) and stars orbiting it. In the early-20th century, the discovery of other galaxies and the development of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Omphalos Of Delphi
The Omphalos of Delphi is an ancient marble monument that was found at the archaeological site of Delphi, Greece. According to the Ancient Greek myths regarding the founding of the Delphic Oracle, the god Zeus, in his attempt to locate the center of the earth, launched two eagles from the two ends of the world, and the eagles, starting simultaneously and flying at equal speed, crossed their paths above the area of Delphi, and so was the place where Zeus placed the stone. Since then, Delphi has been considered by Greeks to be the center of the world, the omphalos "navel of the Earth." The original stone is held in the museum of Delphi; there is a simplified copy at the site where it was found. Description The marble-carved stone that constituted the omphalos in the monument with the tripod and the dancers troubled the excavators, because they could not decide if it was the original or a copy from Hellenistic and Roman times. In the 2nd century AD, Pausanias traveled to the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Barycenter
In astronomy, the barycenter (or barycentre; ) is the center of mass of two or more bodies that orbit one another and is the point about which the bodies orbit. A barycenter is a dynamical point, not a physical object. It is an important concept in fields such as astronomy and astrophysics. The distance from a body's center of mass to the barycenter can be calculated as a two-body problem. If one of the two orbiting bodies is much more massive than the other and the bodies are relatively close to one another, the barycenter will typically be located within the more massive object. In this case, rather than the two bodies appearing to orbit a point between them, the less massive body will appear to orbit about the more massive body, while the more massive body might be observed to wobble slightly. This is the case for the Earth–Moon system, whose barycenter is located on average from Earth's center, which is 75% of Earth's radius of . When the two bodies are of similar mass ...

List Of Districts In Turkey
The 81 provinces of Turkey are divided into 973 districts (''ilçeler''; sing. ''ilçe''). In the early Turkish Republic and in the Ottoman Empire, the corresponding unit was the ''kaza''. Most provinces bear the same name as their respective provincial capital districts. However, many urban provinces, designated as greater municipalities, have a center consisting of multiple districts, such as the provincial capital of Ankara province, The City of Ankara, comprising nine separate districts. Additionally four provinces, Kocaeli, Sakarya, İçel and Hatay have their capital district named differently from their province, as İzmit, Adapazarı, Mersin and Antakya respectively. A district may cover both rural and urban areas. In many provinces, one district of a province is designated the central district (''merkez ilçe'') from which the district is administered. The central district is administered by an appointed provincial deputy governor and other non-central districts by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
