Statistical Bootstrap Model
Rolf Hagedorn (20 July 1919 – 9 March 2003) was a German theoretical physicist who worked at CERN. He is known for the idea that hadronic matter has a "melting point". The Hagedorn temperature is named in his honor. Early life Hagedorn's younger life was deeply marked by the upheavals of World War II in Europe. He graduated from high school in 1937 and was drafted into the German Army. After the war began, he was shipped off into North Africa as an officer in the Rommel Afrika Korps. He was captured in 1943, and spent the rest of the war in an officer prison camp in the United States. Most of the prisoners were young and with nothing to do, Hagedorn and others set up their own 'university' where they taught each other whatever they knew. There, Hagedorn ran into an assistant of David Hilbert, who taught him mathematics. Becoming a physicist When Hagedorn came back home in January 1946, most German universities were destroyed. Because of his training in the Crossville, Tenn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barmen
Barmen is a former industrial metropolis of the region of Bergisches Land, Germany, which merged with four other towns in 1929 to form the city of Wuppertal. Barmen, together with the neighbouring town of Elberfeld founded the first electric suspended monorail tramway system, the Schwebebahn ''floating tram''. History Barmen was a pioneering centre for both the early industrial revolution on the European mainland, and for the socialist movement and its theory. It was the location of one of the first concentration camps in Nazi Germany, KZ Wuppertal-Barmen, later better known as Kemna concentration camp. Oberbarmen (Upper Barmen) is the eastern part of Barmen, and Unterbarmen (Lower Barmen) the western part. One of its claims to fame is the fact that Friedrich Engels, co-author of ''The Communist Manifesto'', was born in Barmen. Another of its claims is the fact that Bayer AG was founded there by Friedrich Bayer and master dyer Johann Friedrich Weskott with the express pur ...

Postdoc
A postdoctoral fellow, postdoctoral researcher, or simply postdoc, is a person professionally conducting research after the completion of their doctoral studies (typically a PhD). The ultimate goal of a postdoctoral research position is to pursue additional research, training, or teaching in order to have better skills to pursue a career in academia, research, or any other field. Postdocs often, but not always, have a temporary academic appointment, sometimes in preparation for an academic faculty position. They continue their studies or carry out research and further increase expertise in a specialist subject, including integrating a team and acquiring novel skills and research methods. Postdoctoral research is often considered essential while advancing the scholarly mission of the host institution; it is expected to produce relevant publications in peer-reviewed academic journals or conferences. In some countries, postdoctoral research may lead to further formal qualificati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crossville, Tennessee
Crossville is a city in and the county seat of Cumberland County, Tennessee, United States. It is part of the Crossville, TN Micropolitan Statistical Area. The population was 12,071 at the 2020 census. History Crossville developed at the intersection of a branch of the Great Stage Road, which connected the Knoxville area with the Nashville area, and the Kentucky Stock Road, a cattle drovers' path connecting Middle Tennessee with Kentucky and later extending south to Chattanooga. These two roads are roughly paralleled by modern US-70 and US-127, respectively. Around 1800, an early American settler named Samuel Lambeth opened a store at this junction, and the small community that developed around it became known as Lambeth's Crossroads. The store was located at what has become the modern intersection of Main Street and Stanley Street, just south of the courthouse. By the time a post office was established in the 1830s, the community had taken the name of "Crossville". In the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Hilbert
David Hilbert (; ; 23 January 1862 – 14 February 1943) was a German mathematician, one of the most influential mathematicians of the 19th and early 20th centuries. Hilbert discovered and developed a broad range of fundamental ideas in many areas, including invariant theory, the calculus of variations, commutative algebra, algebraic number theory, the foundations of geometry, spectral theory of operators and its application to integral equations, mathematical physics, and the foundations of mathematics (particularly proof theory). Hilbert adopted and defended Georg Cantor's set theory and transfinite numbers. In 1900, he presented a collection of problems that set the course for much of the mathematical research of the 20th century. Hilbert and his students contributed significantly to establishing rigor and developed important tools used in modern mathematical physics. Hilbert is known as one of the founders of proof theory and mathematical logic. Life Early life and edu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Internment
Internment is the imprisonment of people, commonly in large groups, without charges or intent to file charges. The term is especially used for the confinement "of enemy citizens in wartime or of terrorism suspects". Thus, while it can simply mean imprisonment, it tends to refer to preventive confinement rather than confinement ''after'' having been convicted of some crime. Use of these terms is subject to debate and political sensitivities. The word ''internment'' is also occasionally used to describe a neutral country's practice of detaining belligerent armed forces and equipment on its territory during times of war, under the Hague Convention of 1907. Interned persons may be held in prisons or in facilities known as internment camps (also known as concentration camps). The term ''concentration camp'' originates from the Spanish–Cuban Ten Years' War when Spanish forces detained Cuban civilians in camps in order to more easily combat guerrilla forces.

Afrika Korps
The Afrika Korps or German Africa Corps (, }; DAK) was the German expeditionary force in Africa during the North African Campaign of World War II. First sent as a holding force to shore up the Italian defense of its African colonies, the formation fought on in Africa, under various appellations, from March 1941 until its surrender in May 1943. The unit's best known commander was Field Marshal Erwin Rommel. History Organization The Afrika Korps formed on 11 January 1941 and one of Hitler's favourite generals, Erwin Rommel, was designated as commander on 11 February. Originally Hans von Funck was to have commanded it, but Hitler loathed von Funck, as he had been a personal staff officer of Werner von Fritsch until von Fritsch was dismissed in 1938. The German Armed Forces High Command ('' Oberkommando der Wehrmacht'', OKW) had decided to send a "blocking force" to Italian Libya to support the Italian army. The Italian 10th Army had been routed by the British Commonwealth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
