Kurd Von Mosengeil
Kurd Friedrich Rudolf von Mosengeil, also Curd Friedrich Rudolf von Mosengeil (* 7 March 1884 in Bonn; † 5 September 1906 at Wildgall in Rieserfernergruppe), was a German physicist. Kurd von Mosengeil was a student of Max Planck. In 1905, the latter became the most prominent early advocate of the theory of special relativity of Albert Einstein. In the subsequent years, Planck published several works, in which he explained further consequences of Einstein's theory. He conveyed his enthusiasm to his assistant Max von Laue and his student Kurd of Mosengeil, who became the first physicists to habilitate and graduate, respectively, in relativity-related subjects. Tragically, Kurd von Mosengeil died in a mountaineering accident in Tyrol in September 1906, as he was completing his doctoral dissertation. Planck and Wilhelm Wien edited his draft for publication in the Annalen der Physik in 1907. The resulting posthumous paper (''Theorie der stationären Strahlung in einem gleichförmig ...

Wildgall
The Wildgall ( it, Collaspro) is, at 3,273 metres above sea level, the third highest peak in the Rieserferner Group, a range in the western part of the High Tauern. It lies within the Italian provinces of South Tyrol in the Rieserferner-Ahrn Nature Park (''Parco Naturale Vedrette di Ries-Aurina'') and appears from the south as a massive pyramid with prominent arêtes. It is the most difficult of the summits of the Rieserferner Group to climb. As a result, it was conquered relatively late. Its first recorded ascent was on 18 August 1872 by Victor Hecht from Prague and mountain guides Johann and Sepp Ausserhofer from Rein in Taufers.''Zeitschrift des Deutschen und Oesterreichischen Alpenvereins'', Vol. IV, Munich, 1873, pp. 221 ff. Today the mountain may be climbed from the Kasseler Hut (Italian: ''Rifugio Roma alla Vedrette di Ries'') to the north in about four hours, but it is rarely attempted.Helmut Dumler: ''Gebietsführer Südtirol 3'', Bergverlag Rudolf Rother, München 1987, ...

Rieserfernergruppe
The Rieserferner Group ( it, Gruppo delle Vedrette di Ries, german: Rieserfernergruppe) is a mountain range in the Austrian Central Alps. Together with the Ankogel Group, Goldberg Group, Glockner Group, Schober Group, Kreuzeck Group, Granatspitze Group, Venediger Group and the Villgraten Mountains the group is part of the High Tauern. The Rieserferner mountains extend across the Austrian state of Tyrol and the Italian province of South Tyrol ( Trentino-South Tyrol region). The mountains mainly lie in South Tyrol, where the greater part is protected within the Rieserferner-Ahrn Nature Park. The Rieserferner Group forms the southwesternmost part of the High Tauern, its foothills running towards the southwest as far as Bruneck in the Puster Valley. Its name is derived from the ''Rieserferner'', a glacier on the northern flank between the Hochgall (highest summit in the range at ) and the Schneebiger Nock (). The Rieserferner Group is rather small in comparison with other Alpine ran ... [...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 app ...

Max Planck
Max Karl Ernst Ludwig Planck (, ; 23 April 1858 – 4 October 1947) was a German theoretical physicist whose discovery of energy quanta won him the Nobel Prize in Physics in 1918. Planck made many substantial contributions to theoretical physics, but his fame as a physicist rests primarily on his role as the originator of quantum theory, which revolutionized human understanding of atomic and subatomic processes. In 1948, the German scientific institution Kaiser Wilhelm Society (of which Planck was twice president) was renamed Max Planck Society (MPG). The MPG now includes 83 institutions representing a wide range of scientific directions. Life and career Planck came from a traditional, intellectual family. His paternal great-grandfather and grandfather were both theology professors in Göttingen; his father was a law professor at the University of Kiel and Munich. One of his uncles was also a judge. Planck was born in 1858 in Kiel, Holstein, to Johann Julius Wilhelm Pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Special Relativity
In physics, the special theory of relativity, or special relativity for short, is a scientific theory regarding the relationship between space and time. In Albert Einstein's original treatment, the theory is based on two postulates: # The laws of physics are invariant (that is, identical) in all inertial frames of reference (that is, frames of reference with no acceleration). # The speed of light in vacuum is the same for all observers, regardless of the motion of the light source or the observer. Origins and significance Special relativity was originally proposed by Albert Einstein in a paper published on 26 September 1905 titled "On the Electrodynamics of Moving Bodies".Albert Einstein (1905)''Zur Elektrodynamik bewegter Körper'', ''Annalen der Physik'' 17: 891; English translatioOn the Electrodynamics of Moving Bodiesby George Barker Jeffery and Wilfrid Perrett (1923); Another English translation On the Electrodynamics of Moving Bodies by Megh Nad Saha (1920).

Albert Einstein
Albert Einstein ( ; ; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist, widely acknowledged to be one of the greatest and most influential physicists of all time. Einstein is best known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are the two pillars of modern physics. His mass–energy equivalence formula , which arises from relativity theory, has been dubbed "the world's most famous equation". His work is also known for its influence on the philosophy of science. He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory. His intellectual achievements and originality resulted in "Einstein" becoming synonymous with "genius". In 1905, a year sometimes described as his ' ...

Max Von Laue
Max Theodor Felix von Laue (; 9 October 1879 – 24 April 1960) was a German physicist who received the Nobel Prize in Physics in 1914 for his discovery of the diffraction of X-rays by crystals. In addition to his scientific endeavors with contributions in optics, crystallography, quantum theory, superconductivity, and the theory of relativity, Laue had a number of administrative positions which advanced and guided German scientific research and development during four decades. A strong objector to Nazism, he was instrumental in re-establishing and organizing German science after World War II. Biography Early years Laue was born in Pfaffendorf, now part of Koblenz, Germany, to Julius Laue and Minna Zerrenner. In 1898, after passing his ''Abitur'' in Strassburg, he began his compulsory year of military service, after which in 1899 he started to study mathematics, physics, and chemistry at the University of Strassburg, the University of Göttingen, and the Ludwig Maximilian ...

County Of Tyrol
The (Princely) County of Tyrol was an estate of the Holy Roman Empire established about 1140. After 1253, it was ruled by the House of Gorizia and from 1363 by the House of Habsburg. In 1804, the County of Tyrol, unified with the secularised prince-bishoprics of Trent and Brixen, became a crown land of the Austrian Empire. From 1867, it was a Cisleithanian crown land of Austria-Hungary. Today the territory of the historic crown land is divided between the Italian autonomous region of Trentino-Alto Adige/Südtirol and the Austrian state of Tyrol. The two parts are today associated again in the Tyrol–South Tyrol–Trentino Euroregion. History Establishment At least since German king Otto I had conquered the former Lombard kingdom of Italy in 961 and had himself crowned Holy Roman Emperor in Rome, the principal passes of the Eastern Alps had become an important transit area. The German monarchs regularly travelled across Brenner or Reschen Pass on their Ital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm Wien
Wilhelm Carl Werner Otto Fritz Franz Wien (; 13 January 1864 – 30 August 1928) was a German physicist who, in 1893, used theories about heat and electromagnetism to deduce Wien's displacement law, which calculates the emission of a blackbody at any temperature from the emission at any one reference temperature. He also formulated an expression for the black-body radiation, which is correct in the photon-gas limit. His arguments were based on the notion of adiabatic invariance, and were instrumental for the formulation of quantum mechanics. Wien received the 1911 Nobel Prize for his work on heat radiation. He was a cousin of Max Wien, inventor of the Wien bridge. Biography Early years Wien was born at Gaffken near Fischhausen, Province of Prussia (now Primorsk, Russia) as the son of landowner Carl Wien. In 1866, his family moved to Drachstein near Rastenburg (now Kętrzyn, Poland). In 1879, Wien went to school in Rastenburg and from 1880 to 1882 he attended the city scho ...

Thermodynamics
Thermodynamics is a branch of physics that deals with heat, work, and temperature, and their relation to energy, entropy, and the physical properties of matter and radiation. The behavior of these quantities is governed by the four laws of thermodynamics which convey a quantitative description using measurable macroscopic physical quantities, but may be explained in terms of microscopic constituents by statistical mechanics. Thermodynamics applies to a wide variety of topics in science and engineering, especially physical chemistry, biochemistry, chemical engineering and mechanical engineering, but also in other complex fields such as meteorology. Historically, thermodynamics developed out of a desire to increase the efficiency of early steam engines, particularly through the work of French physicist Sadi Carnot (1824) who believed that engine efficiency was the key that could help France win the Napoleonic Wars. Scots-Irish physicist Lord Kelvin was the first to formula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
