Geodetic Institute Of Potsdam
The GFZ German Research Centre for Geosciences, also known as GFZ Helmholtz Centre Potsdam or just GFZ, is the national research center for Earth Sciences in Germany, located on the Telegrafenberg in Potsdam, in the German federal state of Brandenburg, and is part of the Helmholtz Association of National Research Centres. "GFZ" stands for ''GeoForschungsZentrum'' (Geo-research Centre). History The GFZ was founded in 1992. It is the latest in a long line of research institutes that have been located on the Telegrafenberg. These have included the Central Institute of for Physics of the Earth (ZIPE), which was an institute of the Academy of Sciences of the GDR (German Democratic Republic) that was actively involved in Geodesy. The history of the GFZ can be traced back to the ', an institution of the Prussian Academy of Sciences. Under the directorship of Friedrich Robert Helmert from 1886 to 1917, the institute developed into the world's leading center for scientific geodesy. T ...

Earth Science
Earth science or geoscience includes all fields of natural science related to the planet Earth. This is a branch of science dealing with the physical, chemical, and biological complex constitutions and synergistic linkages of Earth's four spheres, namely biosphere, hydrosphere, atmosphere, and geosphere. Earth science can be considered to be a branch of planetary science, but with a much older history. Earth science encompasses four main branches of study, the lithosphere, the hydrosphere, the atmosphere, and the biosphere, each of which is further broken down into more specialized fields. There are both reductionist and holistic approaches to Earth sciences. It is also the study of Earth and its neighbors in space. Some Earth scientists use their knowledge of the planet to locate and develop energy and mineral resources. Others study the impact of human activity on Earth's environment, and design methods to protect the planet. Some use their knowledge about Earth proces ...

Research Institutes Established In 1992
Research is "creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion on past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, economic ... [...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] |
Geoid
The geoid () is the shape that the ocean surface would take under the influence of the gravity of Earth, including gravitational attraction and Earth's rotation, if other influences such as winds and tides were absent. This surface is extended through the continents (such as with very narrow hypothetical canals). According to Gauss, who first described it, it is the "mathematical figure of the Earth", a smooth but irregular surface whose shape results from the uneven distribution of mass within and on the surface of Earth. It can be known only through extensive gravitational measurements and calculations. Despite being an important concept for almost 200 years in the history of geodesy and geophysics, it has been defined to high precision only since advances in satellite geodesy in the late 20th century. All points on a geoid surface have the same geopotential (the sum of gravitational potential energy and centrifugal potential energy). The force of gravity acts everywhere ...

Sigmund Jähn
Sigmund Werner Paul Jähn (; 13 February 1937 – 21 September 2019) was a German cosmonaut and pilot who in 1978 became the first German to fly into space as part of the Soviet Union's Interkosmos programme. Early life Jähn was born on 13 February 1937 in Morgenröthe-Rautenkranz, in the Vogtland region of Saxony, Germany. From 1943 to 1951 he attended school in his hometown. He trained as a printer until 1954 and then managed the pioneer program in a local school. On 26 April 1955 he joined the East German Air Force, where he became a pilot. From 1961 to 1963 he was deputy commander for political work as an adamant socialist and in 1965 became responsible for air tactics and air shooting. From 1966 to 1970 he studied at the Gagarin Air Force Academy in Monino, in the Soviet Union. From 1970 to 1976, he worked in the administration of the East German Air Force, responsible for pilot education and flight safety. Jähn (via his father's stories and memorabilia) and his f ...

Nationale Volksarmee
The National People's Army (german: Nationale Volksarmee, ; NVA ) were the armed forces of the German Democratic Republic (GDR) from 1956 to 1990. The NVA was organized into four branches: the (Ground Forces), the (Navy), the (Air Force) and the (Border Troops). The NVA belonged to the Ministry of National Defence and commanded by the National Defense Council of East Germany, headquartered in Strausberg east of East Berlin. From 1962, conscription was mandatory for all GDR males aged between 18 and 60 requiring an 18-month service, and it was the only Warsaw Pact military to offer non-combat roles to conscientious objectors, known as " construction soldiers" (). The NVA reached 175,300 personnel at its peak in 1987. The NVA was formed on 1 March 1956 to succeed the (Barracked People's Police) and under the influence of the Soviet Army became one of the Warsaw Pact militaries opposing NATO during the Cold War. The majority of NATO officers rated the NVA the best milit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Square Academic Caps
The square academic cap, graduate cap, cap, mortarboard (because of its similarity in appearance to the mortarboard used by brickmasons to hold mortar) or Oxford cap is an item of academic dress consisting of a horizontal square board fixed upon a skull-cap, with a tassel attached to the centre. In the UK and the US, it is commonly referred to informally in conjunction with an academic gown as a "cap and gown". It is also sometimes termed a square, trencher, or corner-cap. The adjective academical is also used. The cap, together with the gown and sometimes a hood, now form the customary uniform of a university graduate in many parts of the world, following a British model. Origins The mortarboard may have developed from the biretta, a similar-looking hat worn by Roman Catholic clergy. The biretta itself may have been a development of the Roman ''pileus quadratus'', a type of skullcap with superposed square and tump (meaning small mound). A reinvention of this type of ca ...
