Georg Duffing
Georg Wilhelm Christian Caspar Duffing (born April 11, 1861 in Waldshut; died April 5, 1944 in Schwedt/Oder) was a German engineer and inventor. In 1918, he described vibrations and their resonances mathematically, as the Duffing equation. Georg Duffing's equation for vibration theory is a standard model for nonlinear vibration. Since the 1970s, it has been popular in chaos theory.Ivana Kovacic, Michael J. Brennan: The Duffing Equation: Nonlinear Oscillators and Their Behaviour, John Wiley & Sons, 2011, p. 1 Family and career Georg Duffing was born in 1861 in the Baden town of Waldshut as the eldest son of merchant Christian Duffing and his wife Julie Spies. In 1862, the family moved to Mannheim, where the father-in-law owned a carpentry business. In high school, Duffing showed a particular talent for mathematics and music. Due to a heart defect, he abandoned his initial intention of pursuing a military career and enrolled from 1878 to 1883 at the Karlsruhe Institute of Techno ...

Waldshut-Tiengen
Waldshut-Tiengen (; gsw, label=Alemannic, Waldshuet-Düenge, italic=no), commonly known as Waldshut, is a city in southwestern Baden-Württemberg right at the Swiss border. It is the district seat and at the same time the biggest city in Waldshut district and a "middle centre" in the area of the "high centre" Lörrach/Weil am Rhein to whose middle area most towns and communities in Waldshut district belong (with the exception of seven communities that belong to Bad Säckingen's area). There are furthermore complexities arising from cross-border traffic between this area and the Swiss cantons of Aargau, Schaffhausen and Zürich. This classification relates to Walter Christaller's Central Place Theory, however, and not to any official administrative scheme. The city, which was newly created in the framework of the 1975 municipal reform, at that time passed the 20,000 mark in population. City council then applied to have the city raised to ''Große Kreisstadt'', which the government ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People From Waldshut-Tiengen
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

SS Cap Arcona
SS ''Cap Arcona'', named after Cape Arkona on the island of Rügen, was a large German ocean liner, later a ship of the German Navy, and finally a prison ship. A flagship of the Hamburg Südamerikanische Dampfschifffahrts-Gesellschaft ("Hamburg-South America Line"), she made her maiden voyage on 29 October 1927, carrying passengers and cargo between Germany and the east coast of South America, and in her time was the largest and quickest ship on the route. In 1940 the Kriegsmarine requisitioned ''Cap Arcona'' as an accommodation ship. In 1942 she served as the set for the German propaganda feature film ''Titanic''. In 1945 she evacuated almost 26,000 German civilian refugees from East Prussia before the advance of the Red Army. ''Cap Arcona''s final use was as a prison ship. In May 1945 she was heavily laden with prisoners from Nazi concentration camps when the Royal Air Force bombed her, killing about 5,000 people; with more than 2,000 further casualties in the sinkings of ...

Quantum Physics
Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science. Classical physics, the collection of theories that existed before the advent of quantum mechanics, describes many aspects of nature at an ordinary (macroscopic) scale, but is not sufficient for describing them at small (atomic and subatomic) scales. Most theories in classical physics can be derived from quantum mechanics as an approximation valid at large (macroscopic) scale. Quantum mechanics differs from classical physics in that energy, momentum, angular momentum, and other quantities of a bound system are restricted to discrete values ( quantization); objects have characteristics of both particles and waves (wave–particle duality); and there are limits to ho ...

Westinghouse Electric
The Westinghouse Electric Corporation was an American manufacturing company founded in 1886 by George Westinghouse. It was originally named "Westinghouse Electric & Manufacturing Company" and was renamed "Westinghouse Electric Corporation" in 1945. The company acquired the CBS television network in 1995 and was renamed "CBS Corporation" until being acquired by Viacom in 1999, a merger completed in April 2000. The CBS Corporation name was later reused for one of the two companies resulting from the split of Viacom in 2006. The Westinghouse trademarks are owned by Westinghouse Electric Corporation, and were previously part of Westinghouse Licensing Corporation. The nuclear power business, Westinghouse Electric Company, was spun off from the Westinghouse Electric Corporation in 1999. History Westinghouse Electric was founded by George Westinghouse in Pittsburgh, Pennsylvania, on January 8, 1886. The firm became active in developing electric infrastructure throughout the U ...
