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. In addition, he is also a competent pianist. He is married and has four daughters. His wife Susanne, a home economics teacher, is a cousin of 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-chai ...

Carl Ramsauer
Carl Wilhelm Ramsauer (6 February 1879 – 24 December 1955) was a German professor of physics and research physicist, famous 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. 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.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, 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. Fr ...

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 inelastic if they cause 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 angles, and the probability of collis ...

Johann Georg Ramsauer
Johann Georg Ramsauer (7 March 1795 in Hallstatt – 14 December 1874 in Linz) was an Austrians, Austrian Mining, 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 drawings of grave arrangements and Artefact (archaeology), artefacts, which were never published but rather became the protocol manuscripts.Hodson (1990), p. 4 References Bibliography * External links * {{DEFAULTSORT:Ramsauer, Johann Georg Austrian archaeologists 1795 births 1874 deaths ...

German-language Surnames
German ( ) is a West Germanic language mainly spoken in Central Europe. It is the most widely spoken and official or co-official language in Germany, Austria, Switzerland, Liechtenstein, and the Italian province of South Tyrol. It is also a co-official language of Luxembourg and Belgium, as well as a national language in Namibia. Outside Germany, it is also spoken by German communities in France (Bas-Rhin), Czech Republic (North Bohemia), Poland (Upper Silesia), Slovakia (Bratislava Region), and Hungary (Sopron). German is most similar to other languages within the West Germanic language branch, including Afrikaans, Dutch, English, the Frisian languages, Low German, Luxembourgish, Scots, and Yiddish. It also contains close similarities in vocabulary to some languages in the North Germanic group, such as Danish, Norwegian, and Swedish. German is the second most widely spoken Germanic language after English, which is also a West Germanic language. German is one of the major ...
