Karl Apfelbacher
Karl Apfelbacher was a German mathematician who served as minister for higher public education in Upper Bavaria-East. He was a student of Arnold Sommerfeld and Heinrich Tietze at the University of Munich, where he received his doctorate in 1939. He went into teaching mathematics and science, as well as administration, in secondary schools. In 1964, he was cited as being Oberstudiendirektor at the Oberrealschule in Burghausen, Altötting Burghausen is the largest town in the Altötting district of Upper Bavaria in Germany. It is situated on the Salzach river, near the border with Austria. Burghausen Castle rests along a ridgeline, and is the longest castle in the world (1,043 ....

Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, mathematical structure, structure, space, Mathematical model, models, and mathematics#Calculus and analysis, change. History One of the earliest known mathematicians were Thales of Miletus (c. 624–c.546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. The number of known mathematicians grew when Pythagoras of Samos (c. 582–c. 507 BC) established the Pythagoreans, Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathemat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arnold Sommerfeld
Arnold Johannes Wilhelm Sommerfeld, (; 5 December 1868 – 26 April 1951) was a German theoretical physicist who pioneered developments in atomic and quantum physics, and also educated and mentored many students for the new era of theoretical physics. He served as doctoral supervisor for many Nobel Prize winners in physics and chemistry (only J. J. Thomson's record of mentorship is comparable to his). He introduced the second quantum number ( azimuthal quantum number) and the third quantum number ( magnetic quantum number). He also introduced the fine-structure constant and pioneered X-ray wave theory. Early life and education Sommerfeld was born in 1868 to a family with deep ancestral roots in Prussia. His mother Cäcilie Matthias (1839–1902) was the daughter of a Potsdam builder. His father Franz Sommerfeld (1820–1906) was a physician from a leading family in Königsberg, where Arnold's grandfather had resettled from the hinterland in 1822 for a career as Cour ...

Heinrich Tietze
Heinrich Franz Friedrich Tietze (August 31, 1880 – February 17, 1964) was an Austrian mathematician, famous for the Tietze extension theorem on functions from topological spaces to the real numbers. He also developed the Tietze transformations for group presentations, and was the first to pose the group isomorphism problem. Tietze's graph is also named after him; it describes the boundaries of a subdivision of the Möbius strip into six mutually-adjacent regions, found by Tietze as part of an extension of the four color theorem to non-orientable surfaces. Education and career Tietze was the son of Emil Tietze and the grandson of Franz Ritter von Hauer, both of whom were Austrian geologists. He was born in Schleinz, Austria-Hungary, and studied mathematics at the Technische Hochschule in Vienna beginning in 1898. After additional studies in Munich, he returned to Vienna, completing his doctorate in 1904 and his habilitation in 1908. From 1910 until 1918 Tietze taught math ...

University Of Munich
The Ludwig Maximilian University of Munich (simply University of Munich or LMU; german: link=no, Ludwig-Maximilians-Universität München) is a public research university in Munich, Bavaria, Germany. Originally established as the University of Ingolstadt in 1472 by Duke Ludwig IX of Bavaria-Landshut, it is Germany's sixth-oldest university in continuous operation. In 1800, the university was moved from Ingolstadt to Landshut by King Maximilian I Joseph of Bavaria when the city was threatened by the French, before being transferred to its present-day location in Munich in 1826 by King Ludwig I of Bavaria. In 1802, the university was officially named Ludwig-Maximilians-Universität by King Maximilian I of Bavaria in honor of himself and Ludwig IX. LMU is currently the second-largest university in Germany in terms of student population; in the 2018/19 winter semester, the university had a total of 51,606 matriculated students. Of these, 9,424 were freshmen, while international ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burghausen, Altötting
Burghausen is the largest town in the Altötting district of Upper Bavaria in Germany. It is situated on the Salzach river, near the border with Austria. Burghausen Castle rests along a ridgeline, and is the longest castle in the world (1,043 m). History The oldest mention of Burghausen is documented in the year 1025 as Imperial real property. Emperor Conrad II would later appoint the Counts of Burghausen as the financial administrators of the locality. But, as latest excavations have shown, the area around the main court of Burghausen's castle has at least been inhabited since the Bronze Age. With Archaeologists finding artifacts of the pre-metal Celtic, Iron Age, and Roman era, it is hard to pinpoint a "founding" date. The town has developed over thousands of years, but it is not yet possible to say how long there has been a permanent settlement. In 1164, Duke Henry the Lion took possession of the castle. The Wittelsbachs took possession of the castle in 1180 and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Year Of Birth Missing
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Possibly Living People
Possibility is the condition or fact of being possible. Latin origins of the word hint at ability. Possibility may refer to: * Probability, the measure of the likelihood that an event will occur * Epistemic possibility, a topic in philosophy and modal logic * Possibility theory, a mathematical theory for dealing with certain types of uncertainty and is an alternative to probability theory * Subjunctive possibility, (also called alethic possibility) is a form of modality studied in modal logic. ** Logical possibility, a proposition that will depend on the system of logic being considered, rather than on the violation of any single rule * Possible world, a complete and consistent way the world is or could have been Other *Possible (Italy), a political party in Italy * Possible Peru, a political party in Peru * Possible Peru Alliance, an electoral alliance in Peru Entertainment *''Kim Possible'', a US children's TV series :*Kim Possible (character), the central charact ...
