August Hagenbach
August Hagenbach (22 December 1871 – 11 August 1955) was a Swiss physicist working in spectroscopy. He was the son of physicist Eduard Hagenbach-Bischoff and obtained his Ph.D. in 1894 at the University of Leipzig with a thesis titled ''""'' under the supervision of Gustav Heinrich Wiedemann. In 1906 he took over the chaired professorship at the University of Basel earlier held by his father. In 1926 he was rector of the University of Basel. One of his students was Ernst Stueckelberg Ernst Carl Gerlach Stueckelberg (baptised as Johann Melchior Ernst Karl Gerlach Stückelberg, full name after 1911: Baron Ernst Carl Gerlach Stueckelberg von Breidenbach zu Breidenstein und Melsbach; 1 February 1905 – 4 September 1984) was a S ....SeHistory of Physics Department of Basel University (German) References External links * Brief 'genealogical' information on August Hagenbach* Historisches Lexikon der Schweiz {{DEFAULTSORT:Hagenbach, August 1871 births 1955 deaths Swiss ph ...

Spectroscopy
Spectroscopy is the field of study that measures and interprets the electromagnetic spectra that result from the interaction between electromagnetic radiation and matter as a function of the wavelength or frequency of the radiation. Matter waves and acoustic waves can also be considered forms of radiative energy, and recently gravitational waves have been associated with a spectral signature in the context of the Laser Interferometer Gravitational-Wave Observatory (LIGO) In simpler terms, spectroscopy is the precise study of color as generalized from visible light to all bands of the electromagnetic spectrum. Historically, spectroscopy originated as the study of the wavelength dependence of the absorption by gas phase matter of visible light dispersed by a prism. Spectroscopy, primarily in the electromagnetic spectrum, is a fundamental exploratory tool in the fields of astronomy, chemistry, materials science, and physics, allowing the composition, physical structure and e ...

Eduard Hagenbach-Bischoff
Eduard Hagenbach-Bischoff (20 February 1833, in Basel – 23 December 1910, in Basel) was a Swiss physicist. The Hagenbach-Bischoff quota (a voting system) is named after him. The son of the theologian Karl Rudolf Hagenbach, he studied physics and mathematics in Basel (with Rudolf Merian), Berlin (with Heinrich Wilhelm Dove and Heinrich Gustav Magnus), Geneva, Paris (with Jules Célestin Jamin) and obtained his Ph.D. in 1855 at Basel. He taught at the ''Gewerbeschule'' (vocational school) in Basel and was after his habilitation, a professor of mathematics at the University of Basel for one year. From 1863 to 1906 he was a full professor of physics at Basel (successor of Gustav Heinrich Wiedemann). In 1874 he became director of the institute of physics at the newly founded “Bernoullianum” in Basel, and from 1874 to 1879 he was president of the Swiss Academy of Sciences. Hagenbach-Bischoff was involved in the popularisation of science, and at the “Bernoullianum” he gave m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Leipzig
Leipzig University (german: Universität Leipzig), in Leipzig in Saxony, Germany, is one of the world's oldest universities and the second-oldest university (by consecutive years of existence) in Germany. The university was founded on 2 December 1409 by Frederick I, Elector of Saxony and his brother William II, Margrave of Meissen, and originally comprised the four scholastic faculties. Since its inception, the university has engaged in teaching and research for over 600 years without interruption. Famous alumni include Gottfried Wilhelm von Leibniz, Johann Wolfgang von Goethe, Leopold von Ranke, Friedrich Nietzsche, Robert Schumann, Richard Wagner, Tycho Brahe, Georgius Agricola, Angela Merkel and ten Nobel laureates associated with the university. History Founding and development until 1900 The university was modelled on the University of Prague, from which the German-speaking faculty members withdrew to Leipzig after the Jan Hus crisis and the Decree of Kutná H ...

Gustav Heinrich Wiedemann
Gustav Heinrich Wiedemann (; 2 October 1826 – 24 March 1899) was a German physicist and scientific author. Life Wiedemann was born in Berlin the son of a merchant who died two years later. Following the death of his mother in 1842 he lived with his grandparents. After attending a private school as well as the Cölnische Humanistische Gymnasium, he entered the University of Berlin in 1844 where took his doctor's degree three years later under the supervision of Heinrich Gustav Magnus. His thesis on that occasion was devoted to a question in organic chemistry, for he held the opinion that the study of chemistry is an indispensable preliminary to the pursuit of physics, which was his ultimate aim. In Berlin he made the acquaintance of Hermann von Helmholtz at the house of Heinrich Gustav Magnus and was one of the founders of the Berlin Physical Society. In 1854 he left Germany to take on the role of Professor of Physics in Basel, nine years later he moved to Braunschweig and in ...

University Of Basel
The University of Basel (Latin: ''Universitas Basiliensis'', German: ''Universität Basel'') is a university in Basel, Switzerland. Founded on 4 April 1460, it is Switzerland's oldest university and among the world's oldest surviving universities. The university is traditionally counted among the leading institutions of higher learning in the country. The associated Basel University Library is the largest and among the most important libraries in Switzerland. The university hosts the faculties of theology, law, medicine, humanities and social sciences, science, psychology, and business and economics, as well as numerous cross-disciplinary subjects and institutes, such as the Biozentrum for biomedical research and the Institute for European Global Studies. In 2020, the university had 13,139 students and 378 professors. International students accounted for 27 percent of the student body. In its over 500-year history, the university has been home to Erasmus of Rotterdam, Parac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ernst Stueckelberg
Ernst Carl Gerlach Stueckelberg (baptised as Johann Melchior Ernst Karl Gerlach Stückelberg, full name after 1911: Baron Ernst Carl Gerlach Stueckelberg von Breidenbach zu Breidenstein und Melsbach; 1 February 1905 – 4 September 1984) was a Swiss mathematician and physicist, regarded as one of the most eminent physicists of the 20th century. Despite making key advances in theoretical physics, including the exchange particle model of fundamental forces, causal S-matrix theory, and the renormalization group, his idiosyncratic style and publication in minor journals led to his work not being widely recognized until the mid-1990s. Early life Born into a semi-aristocratic family in Basel in 1905, Stueckelberg's father was a lawyer, and his paternal grandfather a distinguished Swiss artist. A highly gifted school student, Stueckelberg initially began a physics degree at the University of Basel in 1923. Career While still a student, Stueckelberg was invited by the distinguished qua ...
