Franz Serafin Exner (philosopher)
Franz Serafin Exner (24 March 1849 – 15 October 1926) was an Austrian physicist. Life Exner came from one of the most important university families of the Austrian-Hungarian empire. The same Exner family included , , Sigmund Exner, and . Exner was youngest of the five children who survived to adulthood of parents Franz Serafin Exner (1802-1853) and Charlotte Dusensy (1816–1859). His father Franz Serafin was, from 1831 to 1848, a professor of philosophy in Prague and from 1848 onwards a member of the Board of Education in Vienna, becoming an influential reformer of Austrian university education. Franz Exner began his university Physics studies at Vienna in 1867. He received a doctorate from the University of Vienna in 1871, after an academic year at Zürich under August Kundt, also working alongside Wilhelm Conrad Röntgen, Kundt's student and, especially through the 1879s, regular research assistant/partner. The greatest influence on Exner's student career was probab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 physic ...

NDB is published in German by the Historical Commission at the Bavarian Academy of Sciences and Humanities and printed by Duncker & Humblot in Berlin. The index and full-text articles of the first 25 volumes are freely available online via the website ''German Biography'' (''Deutsche Biographie'') and the Biographical Portal.

Die Presse
''Die Presse'' is a German-language daily broadsheet newspaper based in Vienna, Austria. It is considered a newspaper of record for Austria. History and profile ''Die Presse'' was first printed on 3 July 1848 as a liberal (libertarian)-bourgeois newspaper within the meaning of the revolutions of 1848 by the entrepreneur August Zang. Its staff split in 1864 under the leadership of Max Friedländer, Michael Etienne and Adolf Werthner to form the ''Neue Freie Presse'', which later was aryanized by the Nazis in 1938 and effectively closed in 1939. In 1946, after the Second World War, resistance fighter Ernst Molden, who had been vice-editor-in-chief of the ''Neue Freie Presse'' from 1921 until 1939, reestablished the newspaper as ''Die Presse''. The ''"Presse"'' had been struggling for financial survival for a long time, until during the 1960s, the Austrian Chamber of Commerce became the main shareholder. Since 1999 it has been owned by the Styria Medien AG, a conservative-libe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ernst Lecher
Ernst Lecher (1 June 1856 – 19 July 1926) was an Austrian physicist who, from 1909, was head of the ''First Institute of Physics'' in Vienna. He is remembered for developing an apparatus— "Lecher lines"—to measure the wavelength and frequency of electromagnetic waves. He gave his name to the Ernst-Lecher-Institut, a radar research establishment set up in the 1940s in Reichenau an der Rax, Reichenau, south of Vienna, which is now a part of the German research institute Max Planck Institute. Lecher's father, Zacharias K Lecher, was editor of Vienna's leading daily newspaper, ''Die Presse'', and helped to publicise the discovery of X-rays of his Germans, German colleague Wilhelm Röntgen in 1896. Lecher's nephew, Konrad Zacharias Lorenz, won the Nobel Prize in Physiology or Medicine in 1973.John R. Krebs, Sverre Sjölander, ''Konrad Z. Lorenz For. Mem.

X-ray
An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz ( to ) and energies in the range 145 eV to 124 keV. X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays. In many languages, X-radiation is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it on November 8, 1895. He named it ''X-radiation'' to signify an unknown type of radiation.Novelline, Robert (1997). ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th edition. . Spellings of ''X-ray(s)'' in English include the variants ''x-ray(s)'', ''xray(s)'', and ''X ray(s)''. The most familiar use of X-rays is checking for fractures (broken bones), but X-rays are also used in other ways. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Würzburg
Würzburg (; Main-Franconian: ) is a city in the region of Franconia in the north of the German state of Bavaria. Würzburg is the administrative seat of the ''Regierungsbezirk'' Lower Franconia.

New Year
New Year is the time or day currently at which a new calendar year begins and the calendar's year count increments by one. Many cultures celebrate the event in some manner. In the Gregorian calendar, the most widely used calendar system today, New Year occurs on January 1 ( New Year's Day, preceded by New Year's Eve). This was also the first day of the year in the original Julian calendar and the Roman calendar (after 153 BC). Other cultures observe their traditional or religious New Year's Day according to their own customs, typically (though not invariably) because they use a lunar calendar or a lunisolar calendar. Chinese New Year, the Islamic New Year, Tamil New Year (Puthandu), and the Jewish New Year are among well-known examples. India, Nepal, and other countries also celebrate New Year on dates according to their own calendars that are movable in the Gregorian calendar. During the Middle Ages in Western Europe, while the Julian calendar was still in use, au ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Johann Josef Loschmidt
Johann Josef Loschmidt (15 March 1821 – 8 July 1895), who referred to himself mostly as Josef Loschmidt (omitting his first name), was a notable Austrian scientist who performed ground-breaking work in chemistry, physics (thermodynamics, optics, electrodynamics), and crystal forms. Born in Karlsbad, a town located in the Austrian Empire (now Karlovy Vary, Czech Republic), Loschmidt became professor of physical chemistry at the University of Vienna in 1868. He had two early mentors. The first was a Bohemian priest, Adalbert Czech, who persuaded Loschmidt's parents to send young Josef to high school in the Piarist monastery in Schlackenwerth and, in 1837, to advanced high-school classes in Prague. This was followed by two years of philosophy and mathematics at Prague's Charles University, where Loschmidt met his second important mentor. This was the philosophy professor Franz Serafin Exner, whose eyesight was failing, and who asked Loschmidt to be his personal reader. Exner wa ...

Chemical Physics
Chemical physics is a subdiscipline of chemistry and physics that investigates physicochemical phenomena using techniques from atomic and molecular physics and condensed matter physics; it is the branch of physics that studies chemical processes from the point of view of physics. While at the interface of physics and chemistry, chemical physics is distinct from physical chemistry in that it focuses more on the characteristic elements and theories of physics. Meanwhile, physical chemistry studies the physical nature of chemistry. Nonetheless, the distinction between the two fields is vague, and scientists often practice in both fields during the course of their research. The United States Department of Education defines chemical physics as "A program that focuses on the scientific study of structural phenomena combining the disciplines of physical chemistry and atomic/molecular physics. Includes instruction in heterogeneous structures, alignment and surface phenomena, quantum t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
