Danish Mathematical Society
The Danish Mathematical Society (Dansk Matematisk Forening) is a society of Danish mathematicians founded in 1873 at the University of Copenhagen, a year after the French Mathematical Society. According to the society website, it has "the purpose of acting for the benefit of mathematics in research and education." History The society was founded after the idea of Thorvald N. Thiele. The first committee was composed of Thiele, Hieronymus Georg Zeuthen and Julius Petersen. Bodil Branner was the first woman to lead the Danish Mathematical Society, which she did from 1998 to 2002..

Copenhagen
Copenhagen ( ) is the capital and most populous city of Denmark, with a population of 1.4 million in the Urban area of Copenhagen, urban area. The city is situated on the islands of Zealand and Amager, separated from Malmö, Sweden, by the Øresund strait. The Øresund Bridge connects the two cities by rail and road. Originally a Vikings, Viking fishing village established in the 10th century in the vicinity of what is now Gammel Strand, Copenhagen became the capital of Denmark in the early 15th century. During the 16th century, the city served as the ''de facto'' capital of the Kalmar Union and the seat of the Union's monarchy, which governed most of the modern-day Nordic countries, Nordic region as part of a Danish confederation with Sweden and Norway. The city flourished as the cultural and economic centre of Scandinavia during the Renaissance. By the 17th century, it had become a regional centre of power, serving as the heart of the Danish government and Military history ...

Denmark
Denmark is a Nordic countries, Nordic country in Northern Europe.

It is the southernmost of the Scandinavian countries, lying southwest of Sweden, south of Norway, and north of Germany, with which it shares a short border. Denmark proper is situated between the North Sea to the west and the Baltic Sea to the east.The island of Bornholm is offset to the east of the rest of the country, in the Baltic Sea.

Scientist
A scientist is a person who Scientific method, researches to advance knowledge in an Branches of science, area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales ( 624–545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century in science, 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. History The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different er ...

Quantum Mechanical
Quantum mechanics is the fundamental physical theory that describes the behavior of matter and of light; its unusual characteristics typically occur at and below the scale of atoms. Reprinted, Addison-Wesley, 1989, It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science. Quantum mechanics can describe many systems that classical physics cannot. Classical physics can describe many aspects of nature at an ordinary (macroscopic and (optical) microscopic) scale, but is not sufficient for describing them at very small submicroscopic (atomic and subatomic) scales. Classical mechanics can be derived from quantum mechanics as an approximation that is valid at ordinary scales. Quantum systems have bound states that are quantized to discrete values of energy, momentum, angular momentum, and other quantities, in contrast to classical systems where these quantities can be measured co ...

Dihydrogen Cation
The dihydrogen cation or molecular hydrogen ion is a cation (positive ion) with formula H2^+. It consists of two hydrogen nuclei (protons), each sharing a single electron. It is the simplest molecular ion. The ion can be formed from the ionization of a neutral hydrogen molecule (H2) by electron impact. It is commonly formed in molecular clouds in space by the action of cosmic rays. The dihydrogen cation is of great historical, theoretical, and experimental interest. Historically it is of interest because, having only one electron, the equations of quantum mechanics that describe its structure can be solved approximately in a relatively straightforward way, as long as the motion of the nuclei and relativistic and quantum electrodynamic effects are neglected. The first such solution was derived by Ø. Burrau in 1927, just one year after the wave theory of quantum mechanics was published. The theoretical interest arises because an accurate mathematical description, taking into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niels Bohr Institute
The Niels Bohr Institute () is a research institute of the University of Copenhagen. The research of the institute spans astronomy, geophysics, nanotechnology, particle physics, quantum mechanics, and biophysics. Overview The institute was founded in 1921, as the Institute for Theoretical Physics of the University of Copenhagen, by the Danish theoretical physicist Niels Bohr, who had been on the staff of the University of Copenhagen since 1914, and who had been lobbying for its creation since his appointment as professor in 1916. On the 80th anniversary of Niels Bohr's birth – October 7, 1965 – the Institute officially became the Niels Bohr Institute. Much of its original funding came from the charitable foundation of the Carlsberg Group, Carlsberg brewery, and later from the Rockefeller Foundation. During the 1920s, and 1930s, the institute was the center of the developing disciplines of atomic physics and quantum physics. Physicists from across Europe (and sometimes furthe ...

Geodætisk Institut
Geodætisk Institut (1928–1987) was a Danish state-run cartographic institute. It was created by law number 82, of 31 March 1928, combining Generalstabens Topografiske Afdeling and Den danske Gradmaaling, two institutions that did somewhat overlapping cartographic and topographic mapping of Denmark. It was initially part of Ministry of War (Krigsministeret), later Ministry of Defence (Forsvarsministeret). In the years 1940–1953 ''Geodætisk Institut'' made the second nationwide precision landscape levelling of Denmark. The first was done 1885–1905 by ''Den danske Gradmaaling''. The height fix point remains Århus Domkirke ( Dansk Normal Nul (DNN)), as established in 1905. A third levelling was done 1982–1994. This formed the basic for the new height system DVR90, replacing DNN. The height fix point remains Aarhus Domkirke, however its kote was changed from 5.6150m to 5.570m in DVR90. ''Geodætisk Institut'' made the third topographic mapping of Denmark in the years 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
