Walter Zürn
Walter Zürn (born August 21, 1937) is a German physicist and seismologist. His field of interest is tides and seismic vibrations. The Zurn Peak (1515m) in Antarctica is named for him. Education Zurn studied physics in Stuttgart, Germany. He wrote his thesis at the "Institute of Metal Physics". Career After graduation, he spent four years at the "University of California" (UCLA). Antarctic research From 1971 to 1972, Zurn was Science Manager at the Amundsen–Scott South Pole Station in Antarctica. He said of the station, :"This spot at the bottom of the world is a good observation post for numerous reasons including altitude, high magnetic latitude, remoteness from human interference and the ocean." Research in Germany Walter Zürn returned to Germany in 1974. He worked in the newly founded German Geophysical Society at the Universities of Stuttgart and Karlsruhe. In the 1980s, he worked with Gerhard Müller on experiments on Newton's law of universal gravitation Newton's la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applie ...

Seismologist
Seismology (; from Ancient Greek σεισμός (''seismós'') meaning "earthquake" and -λογία (''-logía'') meaning "study of") is the scientific study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies. It also includes studies of earthquake environmental effects such as tsunamis as well as diverse seismic sources such as volcanic, tectonic, glacial, fluvial, oceanic, atmospheric, and artificial processes such as explosions. A related field that uses geology to infer information regarding past earthquakes is paleoseismology. A recording of Earth motion as a function of time is called a seismogram. A seismologist is a scientist who does research in seismology. History Scholarly interest in earthquakes can be traced back to antiquity. Early speculations on the natural causes of earthquakes were included in the writings of Thales of Miletus (c. 585 BCE), Anaximenes of Miletus (c. 550 BCE), Aristotle (c. 340 BCE), and Zhan ...

Zurn Peak
Toney Mountain is an elongated snow-covered shield volcano, long and rising to at Richmond Peak, located southwest of Kohler Range in Marie Byrd Land, Antarctica. Toney Mountain is an elongated volcanic massif that rises from a basaltic lava plateau. A wide summit caldera tops the volcano, and is elongated in east-west direction; this orientation is shared with calderas on other volcanoes in Marie Byrd Land and reflects regional tectonic stress. The slopes of the volcano feature parasitic vents and glacial corries, and are much steeper north of the volcano than south of it. Most of the mountain is covered by ice and its eastern sector may be a crater. That the mountain is mostly ice covered makes it difficult to determine its composition, the origin of the elongated shape of the volcano and the volcanological relation between the parasitic cinder cones and the main volcanic pile. Its volume may be about . The plateau and parasitic cones are formed by hawaiite and the few out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The nation's capital and most populous city is Berlin and its financial centre is Frankfurt; the largest urban area is the Ruhr. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amundsen–Scott South Pole Station
The Amundsen–Scott South Pole Station is the United States scientific research station at the South Pole of the Earth. It is the southernmost point under the jurisdiction (not sovereignty) of the United States. The station is located on the high plateau of Antarctica at above sea level. It is administered by the Office of Polar Programs of the National Science Foundation, specifically the United States Antarctic Program (USAP). It is named in honor of Norwegian Roald Amundsen and Briton Robert F. Scott, who led separate teams that raced to become the first to the pole in the early 1900s. The original Amundsen–Scott Station was built by Navy Seabees for the federal government of the United States during November 1956, as part of its commitment to the scientific goals of the International Geophysical Year, an effort lasting from January 1957 through June 1958 to study, among other things, the geophysics of the polar regions of Earth.

German Geophysical Society
The German Geophysical Society (german: Deutsche Geophysikalische Gesellschaft, DGG) is a society for geophysics in Germany; it was founded on 19 Sep 1922 in Leipzig, Germany on the initiative of the seismologist Emil Wiechert, as the Deutsche Seismologische Gesellschaft (German Seismological Society). Among its founding members were also Karl Erich Andrée, , , Beno Gutenberg, Franz Kossmat, , , , , and August Heinrich Sieberg. In 1924, it changed its name into ''German Geophysical Society''. Its main activities include the organization of an annual scientific conference of geophysicists mostly of German-speaking countries (or close personal or professional ties to them) and the publication of a major scientific journal, the ''Geophysical Journal International'' (GJI) in cooperation with the Royal Astronomical Society. The DGG also organizes seminars and workshops on specific scientific topics for its members and offers information and advice on issues related to the organization o ...

Gerhard Müller (geophysicist)
Gerhard Müller (November 25, 1940 – July 9, 2002) was a prominent German geophysicist who specialized in seismology. Gerhard Müller was born in 1940 at the foot of the Swabian Alps, in Schwäbisch Gmünd, Germany. He studied geophysics at the University of Mainz, graduating in 1965. He then moved to the Clausthal University of Technology, where he served as scientific assistant from 1965 to 1969, and earned his Ph.D. in 1967.

Newton's Law Of Universal Gravitation
Newton's law of universal gravitation is usually stated as that every particle attracts every other particle in the universe with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers.It was shown separately that separated spherically symmetrical masses attract and are attracted as if all their mass were concentrated at their centers. The publication of the law has become known as the " first great unification", as it marked the unification of the previously described phenomena of gravity on Earth with known astronomical behaviors. This is a general physical law derived from empirical observations by what Isaac Newton called inductive reasoning. It is a part of classical mechanics and was formulated in Newton's work '' Philosophiæ Naturalis Principia Mathematica'' ("the ''Principia''"), first published on 5 July 1687. When Newton presented Book 1 of the unpublished text in April 1686 to the Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
