Mount Wilson Observatory
The Mount Wilson Observatory (MWO) is an astronomical observatory in Los Angeles County, California, United States. The MWO is located on Mount Wilson, a peak in the San Gabriel Mountains near Pasadena, northeast of Los Angeles. The observatory contains two historically important telescopes: the Hooker telescope, which was the largest aperture telescope in the world from its completion in 1917 to 1949, and the 60-inch telescope which was the largest operational telescope in the world when it was completed in 1908. It also contains the Snow solar telescope completed in 1905, the 60 foot (18 m) solar tower completed in 1908, the 150 foot (46 m) solar tower completed in 1912, and the CHARA array, built by Georgia State University, which became fully operational in 2004 and was the largest optical interferometer in the world at its completion. Due to the inversion layer that traps warm air and smog over Los Angeles, Mount Wilson has steadier air than any other location in Nor ...

Deutsche Physik
''Deutsche Physik'' (, "German Physics") or Aryan Physics (german: Arische Physik) was a nationalist movement in the German physics community in the early 1930s which had the support of many eminent physicists in Germany. The term was taken from the title of a four-volume physics textbook by Nobel Laureate Philipp Lenard in the 1930s. ''Deutsche Physik'' was opposed to the work of Albert Einstein and other modern theoretically based physics, which was disparagingly labeled "Jewish physics" (german: Jüdische Physik). Origins This movement began as an extension of a German nationalistic movement in the physics community which went back as far as World War I. On 25 August 1914, during the German invasion of Belgium, German troops used petrol to set fire to the library of the Katholieke Universiteit Leuven. The burning of the library led to a protest note which was signed by eight distinguished British scientists, namely William Bragg, William Crookes, Alexander Fleming, ...

Doktorvater
A doctoral advisor (also dissertation director, dissertation advisor; or doctoral supervisor) is a member of a university faculty whose role is to guide graduate students who are candidates for a doctorate, helping them select coursework, as well as shaping, refining and directing the students' choice of sub- discipline in which they will be examined or on which they will write a dissertation. Students generally choose advisors based on their areas of interest within their discipline, their desire to work closely with particular graduate faculty, and the willingness and availability of those faculty to work with them. In some countries, the student's advisor serves as the chair of the dissertation committee or the examination committee. In some cases, though, the person who serves those roles may be different from the faculty member who has most closely advised the student. For instance, in the Dutch academic system, only full professors (''hoogleraren'') and associate profess ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dynamit Nobel AG
Dynamit Nobel AG is a German chemical and weapons company whose headquarters is in Troisdorf, Germany. It was founded in 1865 by Alfred Nobel. Creation After the death of his younger brother Emil in an 1864 nitroglycerin explosion at the family's armaments factory in Heleneborg, Stockholm, Nobel founded Nitroglycerin AB in Vinterviken, Stockholm. A year later, having found some German business partners, he launched the Alfred Nobel & Company in Germany, building an isolated factory in the Krümmel hills of Geesthacht near Hamburg. This business exported a liquid combination of nitroglycerin and gunpowder known as "Blasting Oil", but it was extremely unstable and difficult to transport, as shown in numerous catastrophes. The buildings of the Krümmel factory itself were destroyed in 1866 and again in 1870. In April 1866, the company shipped three unmarked crates of nitroglycerin to California for the Central Pacific Railroad, who wished to experiment with its blasting capabi ...
