Arthur Haas
Arthur Erich Haas (April 30, 1884 in Brno – February 20, 1941 in Chicago) was an Austrian physicist, noted for a 1910 paper he submitted in support of his habilitation as ''Privatdocent'' at the University of Vienna that outlined a treatment of the hydrogen atom involving quantization of electronic orbitals, thus anticipating the Bohr model (1913) by three years. Haas’ paper, however, was initially rejected and even ridiculed. As noted in his autobiography, Haas recalls: "When I lectured to the Chemical-Physical Society of Vienna ... Lecher ... referred to the presentation during open discussion as a carnival joke" (the lecture was held during carnival time in Austria, February 1910). Soon thereafter, however, by September 1911 at a physical science convention in Karlsruhe, former detractors of Haas' work acknowledged it with greater enthusiasm as noted in a footnote: "We do not know what caused change of mind in 1911 and can merely suggest the general trend of thinking ...

Brackets
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. Typically deployed in symmetric pairs, an individual bracket may be identified as a 'left' or 'right' bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the Writing system#Directionality, directionality of the context. Specific forms of the mark include parentheses (also called "rounded brackets"), square brackets, curly brackets (also called 'braces'), and angle brackets (also called 'chevrons'), as well as various less common pairs of symbols. As well as signifying the overall class of punctuation, the word "bracket" is commonly used to refer to a specific form of bracket, which varies from region to region. In most English-speaking countries, an unqualified word "bracket" refers to the parenthesis (round bracket); in the United States, the square bracket. Glossary of mathematical sym ...

University Of Notre Dame
The University of Notre Dame du Lac, known simply as Notre Dame ( ) or ND, is a private Catholic research university in Notre Dame, Indiana, outside the city of South Bend. French priest Edward Sorin founded the school in 1842. The main campus covers 1,261 acres (510 ha) in a suburban setting and contains landmarks such as the Golden Dome, the ''Word of Life'' mural (commonly known as ''Touchdown Jesus''), Notre Dame Stadium, and the Basilica. Originally for men, although some women earned degrees in 1918, the university began formally accepting undergraduate female students in 1972. Notre Dame has been recognized as one of the top universities in the United States. The university is organized into seven schools and colleges. Notre Dame's graduate program includes more than 50 master, doctoral and professional degrees offered by the six schools, including the Notre Dame Law School and an MD–PhD program offered in combination with the Indiana University School of Medicine ...

Aeiou Encyclopedia
Austria-Forum is a freely accessible online collection of reference works in both German language, German and English language, English about Austria-related topics. Background The predecessor of Austria-Forum, the AEIOU project was launched in 1996 by the Austrian Federal Ministry for Science and Research as part of Austria's millennial celebrations. The first mention of the name ''Ostarrîchi'', or Austria was in the year 996. The content was based on the German-language ''Österreich-Lexikon'', first published in a printed version in 1995. Additional material was acquired, including more images and also audio and video files, and ''AEIOU'' soon grew into a multimedia information system. The title ''AEIOU''—the "Annotatable Electronic Interactive Oesterreich Universal Information System"—is an allusion to the old Habsburg motto, A.E.I.O.U. Suggestions for the improvements to articles can be made by reader; however, the ''aeiou Encyclopedia'' was not a wiki. See also * Li ...

History Of Quantum Mechanics
The history of quantum mechanics is a fundamental part of the history of modern physics. Quantum mechanics' history, as it interlaces with the history of quantum chemistry, began essentially with a number of different scientific discoveries: the 1838 discovery of cathode rays by Michael Faraday; the 1859–60 winter statement of the black-body radiation problem by Gustav Kirchhoff; the 1877 suggestion by Ludwig Boltzmann that the energy states of a physical system could be ''discrete''; the discovery of the photoelectric effect by Heinrich Hertz in 1887; and the 1900 quantum hypothesis by Max Planck that any energy-radiating atomic system can theoretically be divided into a number of discrete "energy elements" ''ε'' (Greek letter epsilon) such that each of these energy elements is proportional to the frequency ''ν'' with which each of them individually radiate energy, as defined by the following formula: : \varepsilon = h \nu, where ''h'' is a numerical value called Planck's ...

Akademische Verlagsgesellschaft
The (AVG, AVg, Aka, AV; English: Academic publishing company) in Leipzig was an important German academic publisher, which was founded in 1906. The original Jewish owners of the publishing house and key employees were expropriated during the time of the Nazi regime, emigrated and founded new scientific publishing houses in other countries. The publishing house was then named . After World War II, in the German Democratic Republic (GDR/DDR) the Leipzig branch of the publishing house was transformed into in 1947 and 1951. This was dissolved in 1991 as a consequence of the German reunification. Between 1953 and 1983, another seeing itself as the legal successor of the original company existed in the Federal Republic of Germany (FRG/BRD) in Frankfurt am Main and Wiesbaden. Today, there are two German publishing houses claiming to stand in the tradition of the , AULA-Verlag and AKA-Verlag, although legally they are new and independent foundations.

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 Pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hendrik Lorentz
Hendrik Antoon Lorentz (; 18 July 1853 – 4 February 1928) was a Dutch physicist who shared the 1902 Nobel Prize in Physics with Pieter Zeeman for the discovery and theoretical explanation of the Zeeman effect. He also derived the Lorentz transformation underpinning Albert Einstein's special theory of relativity, as well as the Lorentz force, which describes the combined electric and magnetic forces acting on a charged particle in an electromagnetic field. Lorentz was also responsible for the Lorentz oscillator model, a classical model used to describe the anomalous dispersion observed in dielectric materials when the driving frequency of the electric field was near the resonant frequency, resulting in abnormal refractive indices. According to the biography published by the Nobel Foundation, "It may well be said that Lorentz was regarded by all theoretical physicists as the world's leading spirit, who completed what was left unfinished by his predecessors and prepared t ...

Solvay Conference
The Solvay Conferences (french: Conseils Solvay) have been devoted to outstanding preeminent open problems in both physics and chemistry. They began with the historic invitation-only 1911 Solvay Conference on Physics, considered a turning point in the world of physics, and continue to the present day. Following the initial success of 1911, they have since been organised by the International Solvay Institutes for Physics and Chemistry, founded by the Belgian industrialist Ernest Solvay in 1912 and 1913, and located in Brussels. The institutes coordinate conferences, workshops, seminars, and colloquia. Recent Solvay Conferences usually go through a three year cycle: the Solvay Conference on Physics, followed by a gap year, followed by the Solvay Conference on Chemistry. Notable Solvay conferences First conference Hendrik Lorentz was chairman of the first Solvay Conference on Physics, held in Brussels from 30 October to 3 November 1911.
