Bohr Unit
Niels Henrik David Bohr (; 7 October 1885 – 18 November 1962) was a Danish physicist who made foundational contributions to understanding atomic structure and old quantum theory, quantum theory, for which he received the Nobel Prize in Physics in 1922. Bohr was also a philosopher and a promoter of scientific research. Bohr developed the Bohr model of the atom, in which he proposed that energy levels of electrons are discrete and that the electrons revolve in stable orbits around the atomic nucleus but can jump from one energy level (or orbit) to another. Although the Bohr model has been supplanted by other models, its underlying principles remain valid. He conceived the principle of Complementarity (physics), complementarity: that items could be separately analysed in terms of contradictory properties, like behaving as a Wave–particle duality, wave or a stream of particles. The notion of complementarity dominated Bohr's thinking in both science and philosophy. Bohr found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copenhagen
Copenhagen ( or .; da, København ) is the capital and most populous city of Denmark, with a proper population of around 815.000 in the last quarter of 2022; and some 1.370,000 in the urban area; and the wider Copenhagen metropolitan area has 2,057,142 people. Copenhagen is 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. Beginning in the 17th century, it consolidated its position as a regional centre of power with its institutions, defences, and armed forces. During the Renaissance the city served as the de facto capital of the Kalmar Union, being the seat of monarchy, governing the majority of the present day Nordic countries, Nordic region in a personal union with Sweden and N ...

Thorvald Thiele
Thorvald Nicolai Thiele (24 December 1838 – 26 September 1910) was a Danish astronomer and director of the Copenhagen Observatory. He was also an actuary and mathematician, most notable for his work in statistics, interpolation and the three-body problem. Thiele made notable contributions to the statistical study of random time series and introduced the cumulants and likelihood functions, and was considered to be one of the greatest statisticians of all time by Ronald Fisher. In the early 1900s he also developed and proposed a generalisation of approval voting to multiple winner elections called sequential proportional approval voting, which was briefly used for party lists in Sweden when proportional representation was introduced in 1909. Thiele also was a founder and Mathematical Director of the Hafnia Insurance Company and led the founding of the Danish Society of Actuaries. It was through his insurance work that he came into contact with fellow mathematician Jørgen Pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harald Høffding
Harald Høffding (11 March 1843 – 2 July 1931) was a Danish philosopher and theologian. Life Born and educated in Copenhagen, he became a schoolmaster, and ultimately in 1883 a professor at the University of Copenhagen. He was strongly influenced by Søren Kierkegaard in his early development, but later became a positivist, retaining and combining with it the spirit and method of practical psychology and the critical school. The physicist Niels Bohr studied philosophy from and became a friend of Høffding. The philosopher and author Ágúst H. Bjarnason was a student of Høffding. Høffding's great-nephew was the statistician Wassily Hoeffding. Høffding died in Copenhagen. Work His best-known work is perhaps his ''Den nyere Filosofis Historie'' (1894), translated into English from the German edition (1895) by B.E. Meyer as ''History of Modern Philosophy'' (2 vols., 1900), a work intended by him to supplement and correct that of Hans Brøchner, to whom it is dedicated ...

Christian Christiansen (physicist)
Christian Christiansen (9 October 1843 in Lønborg, Denmark – 28 November 1917 Frederiksberg) was a Danish physicist. Christiansen first taught at the local polytechnical school. In 1886, he was appointed to a chair for physics at the University of Copenhagen. He mainly studied radiant heat and optical dispersion, discovering the Christiansen effect (Christiansen filter). Around 1917, he discovered the anomalous dispersion of numerous dyes, including aniline red (fuchsine), by recording absorption spectra. In 1884, he confirmed the Stefan–Boltzmann law. Christiansen was elected a member of the Royal Swedish Academy of Sciences in 1902. He was doctoral advisor to Niels Bohr. In 1912, he retired and Martin Knudsen Martin Hans Christian Knudsen (February 15, 1871 in Hasmark on Funen – May 27, 1949 in Copenhagen) was a Danish physicist who taught and conducted research at the Technical University of Denmark.

Quantum Mechanics
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 limit ...

Atomic Physics
Atomic physics is the field of physics that studies atoms as an isolated system of electrons and an atomic nucleus. Atomic physics typically refers to the study of atomic structure and the interaction between atoms. It is primarily concerned with the way in which electrons are arranged around the nucleus and the processes by which these arrangements change. This comprises ions, neutral atoms and, unless otherwise stated, it can be assumed that the term ''atom'' includes ions. The term ''atomic physics'' can be associated with nuclear power and nuclear weapons, due to the synonymous use of ''atomic'' and ''nuclear'' in standard English. Physicists distinguish between atomic physics—which deals with the atom as a system consisting of a nucleus and electrons—and nuclear physics, which studies nuclear reactions and special properties of atomic nuclei. As with many scientific fields, strict delineation can be highly contrived and atomic physics is often considered in the wider ...

Physics
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physics ...

Order Of The Elephant
The Order of the Elephant ( da, Elefantordenen) is a Danish order of chivalry and is Denmark's highest-ranked honour. It has origins in the 15th century, but has officially existed since 1693, and since the establishment of constitutional monarchy in 1849, is now almost exclusively used to honour royalty and heads of state. History A Danish religious confraternity called the Fellowship of the Mother of God, limited to about fifty members of the Danish aristocracy, was founded during the reign of Christian I during the 15th century. The badge of the confraternity showed the Virgin Mary holding her Son within a crescent moon and surrounded with the rays of the sun, and was hung from a collar of links in the form of elephants much like the present collar of the Order. After the Reformation in 1536 the confraternity died out, but a badge in the form of an elephant with his profile on its right side was still awarded by Frederick II. This latter badge may have been inspi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
