Johannes Heydenreich
Johannes Heydenreich (June 20, 1930, in Plauen, Vogtland – June 24, 2015, in Halle (Saale)) was a German physicist who researched on the applications of electron microscopy in solid state physics and materials science. Education and career Heydenreich was born in Plauen near Dresden. Heydenreich studied physics at the Pädagogische Hochschule "Karl Liebknecht" Potsdam from 1953 to 1958. In 1961, he was awarded a doctorate for his work on the visualization of surface defects of geometrical and electrical origin using a "straight-viewing" electron mirror (''Sichtbarmachung von Oberflächenstörungen geometrischen und elektrischen Ursprungs mit Hilfe eines „geradsichtigen“ Elektronenspiegels'') under Johannes Picht. It was during this time that he met the physicist Heinz Bethge, with whom he had a lifelong friendship. In 1962, Heydenreich became deputy director of the Institute for Solid State Physics and Electron Microscopy (IFE) of the Academy of Sciences of the GDR in Hal ...

Academic Staff Of The Martin Luther University Of Halle-Wittenberg
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of tertiary education. The name traces back to Plato's school of philosophy, founded approximately 386 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. The Royal Spanish Academy defines academy as scientific, literary or artistic society established with public authority and as a teaching establishment, public or private, of a professional, artistic, technical or simply practical nature. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

TU Chemnitz
Chemnitz University of Technology () is a public university in Chemnitz, Germany. With around 8,300 students, it is the third largest university in Saxony. It was founded in 1836 as ''Königliche Gewerbschule'' (Royal Mercantile College) and was elevated to a ''Technische Hochschule'', a university of technology, in 1963. With approximately 2,400 employees in science, engineering and management, Chemnitz University of Technology is among the most important employers in the region. History Foundation The tradition of science in this region goes back to the 16th century when Georg Agricola (1494–1555), a famous German scholar of minerals, served as the city's mayor. Historically, the university emerged from the ''Gewerbschule'' (trade school) founded in 1836. One year later, a ''Baugewerkenschule'' (school for the building trades) became affiliated with the ''Königliche Gewerbschule'' (Royal Trade School), which was followed by a ''Königliche Werkmeisterschule'' (Royal Sch ...

Vogtland
Vogtland (; ) is a region spanning the German states of Bavaria, Saxony and Thuringia and north-western Bohemia in the Czech Republic. It overlaps with and is largely contained within Euroregio Egrensis. The name alludes to the former leadership by the Vögte ("advocates" or "lords protector") of Weida, Gera and Plauen. Geography Natural geography The landscape of the Vogtland is sometimes described as idyllic, thanks to its fields, meadows and wooded hilltops. In the south and southeast, Vogtland rises to a low or mid-height mountain range also called ''Oberes Vogtland'', or Upper Vogtland. Here, monocultural coniferous forest is the predominant form of vegetation. The Vogtland's highest mountain is Schneehübel, reaching 974 metres; another remarkable landmark is the Schneckenstein, 883 m above sea level, which gained some renown for its (falsely) alleged unique abundance of topaz crystals. Its mountains spread from Ore Mountains in the south-east to Ficht ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
