Peter Ramsauer
Peter Ramsauer (born 10 February 1954) is a German politician of the Christian Social Union in Bavaria (CSU) who served as the Federal Minister of Transport, Building and Urban Development in the Second Merkel cabinet. Early life and education Ramsauer completed his ''Abitur'' at the Staatliches Landschulheim Marquartstein gymnasium in 1973—with a year abroad at Eton College—and studied business economics at the Ludwig Maximilian University of Munich, where he obtained his Diploma in 1979 and his PhD in 1985. Ramsauer has also qualified as a professional miller in accordance with the traditional occupation of his ancestry. He speaks English and French. He is married and has four daughters. His wife Susanne, a home economics teacher, is a cousin of German-American actress Sandra Bullock. Political career Ramsauer joined the conservative Young Union (JU) youth organisation in 1972 and the CSU in 1973. He was elected Bavarian vice-chairman of the JU in 1983 and vice-chai ...

Carl Ramsauer
Carl Wilhelm Ramsauer (; 6 February 1879 – 24 December 1955) was a German physicist known for the discovery of the Ramsauer–Townsend effect. He pioneered the field of electron and proton collisions with gas molecules.Mehra, Volume 1, Part 2, 2001, p. 620. Life Early life Ramsauer was born in Osternburg, Oldenburg. From 1897 to 1907, he studied at the Munich, Tübingen, Berlin, Kiel, London, and Breslau universities. He was awarded his doctorate at Kiel University.Hentschel, 1966, Appendix F, pp. XLII-XLII. Career From 1907 to 1909, Ramsauer was a teaching assistant to Philipp Lenard in the physics department at the Ruprecht Karl University of Heidelberg. It was here that he conducted research on the quantum effect of the transparency of noble gases to slow electrons, now known as the Ramsauer–Townsend effect. Subsequently, he was a staff scientist at the Radiological Institute in Heidelberg. During World War I, he served as an artillery officer. From 1921, he w ...

Ramsauer–Townsend Effect
The Ramsauer–Townsend effect, also sometimes called the Ramsauer effect or the Townsend effect, is a physical phenomenon involving the scattering of low-energy electrons by atoms of a noble gas. This effect is a result of quantum mechanics. The effect is named for Carl Ramsauer and John Sealy Townsend, who each independently studied the collisions between atoms and low-energy electrons in 1921. Definitions When an electron moves through a gas, its interactions with the gas atoms cause scattering to occur. These interactions are classified as Elasticity (physics), inelastic if they cause excited state, excitation or ionization of the atom to occur and elastic if they do not. The probability of scattering in such a system is defined as the number of electrons scattered, per unit electron current, per unit path length, per unit pressure at 0 °C, per unit solid angle. The number of collisions equals the total number of electrons scattered elastically and inelastically in all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Georg Ramsauer
Johann Georg Ramsauer (7 March 1795 in Hallstatt – 14 December 1874 in Linz) was an Austrian mine operator and the director of the excavations at the Hallstatt cemetery from 1846 to 1863. He spent his life working for the state service of the mines, moving from an apprentice to Bergmeister. During this time, he lived in the Rudolfsturm, a medieval fortress, where he raised 24 children. He kept comprehensive field notes, including magnificent watercolor Watercolor (American English) or watercolour (Commonwealth English; see American and British English spelling differences#-our, -or, spelling differences), also ''aquarelle'' (; from Italian diminutive of Latin 'water'), is a painting metho ... drawings of grave arrangements and artefacts, which were never published but rather became the protocol manuscripts.Hodson (1990), p. 4 References Bibliography * External links * {{DEFAULTSORT:Ramsauer, Johann Georg Businesspeople from the Austrian Empire Archaeologists ...
