Dresden
Dresden (, ; Upper Saxon: ''Dräsdn''; wen, label=Upper Sorbian, Drježdźany) is the capital city of the German state of Saxony and its second most populous city, after Leipzig. It is the 12th most populous city of Germany, the fourth largest by area (after Berlin, Hamburg and Cologne), and the third most populous city in the area of former East Germany, after Berlin and Leipzig. Dresden's urban area comprises the towns of Freital, Pirna, Radebeul, Meissen, Coswig, Radeberg and Heidenau and has around 790,000 inhabitants. The Dresden metropolitan area has approximately 1.34 million inhabitants. Dresden is the second largest city on the River Elbe after Hamburg. Most of the city's population lives in the Elbe Valley, but a large, albeit very sparsely populated area of the city east of the Elbe lies in the West Lusatian Hill Country and Uplands (the westernmost part of the Sudetes) and thus in Lusatia. Many boroughs west of the Elbe lie in the foreland of the Ore Mounta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freiberg, Saxony
Freiberg is a university and former mining town in Saxony, Germany. It is a so-called ''Große Kreisstadt'' (large county town) and the administrative centre of Mittelsachsen district. Its historic town centre has been placed under heritage conservation and is a part of the UNESCO World Heritage Site known as the Ore Mountain Mining Region, due to its exceptional testimony to the development of mining techniques across many centuries. Until 1969, the town was dominated for around 800 years by the mining and smelting industries. In recent decades it has restructured into a high technology site in the fields of semiconductor manufacture and solar technology, part of Silicon Saxony. It is home of the oldest university of mining and metallurgy in the world – the Freiberg University of Mining and Technology. Geography Location The town lies on the northern declivity of the Ore Mountains, with the majority of the borough west of the Eastern or Freiberger Mulde river. Part ...

Indium
Indium is a chemical element with the symbol In and atomic number 49. Indium is the softest metal that is not an alkali metal. It is a silvery-white metal that resembles tin in appearance. It is a post-transition metal that makes up 0.21 parts per million of the Earth's crust. Indium has a melting point higher than sodium and gallium, but lower than lithium and tin. Chemically, indium is similar to gallium and thallium, and it is largely intermediate between the two in terms of its properties. Indium was discovered in 1863 by Ferdinand Reich and Hieronymous Theodor Richter by spectroscopic methods. They named it for the indigo blue line in its spectrum. Indium was isolated the next year. Indium is a minor component in zinc sulfide ores and is produced as a byproduct of zinc refinement. It is most notably used in the semiconductor industry, in low-melting-point metal alloys such as solders, in soft-metal high-vacuum seals, and in the production of transparent conductive coati ...

Ferdinand Reich
Ferdinand Reich (19 February 1799 – 27 April 1882) was a German chemist who co-discovered indium in 1863 with Hieronymous Theodor Richter. Reich was born in Bernburg and died in Freiberg. He was color blind, or could only see in whites and blacks, and that is why Theodor Richter became his science partner. Richter would examine the colors produced in reactions that they studied. Reich and Richter ended up isolating the indium, creating a small supply, although it was later found in more regions. They isolated the indium at the Freiberg University of Mining and Technology The Technische Universität Bergakademie Freiberg (abbreviation: TU Bergakademie Freiberg, TUBAF) is a public university of technology with currently 3655 students in the city of Freiberg, Saxony, Germany.

Corps Saxo-Borussia Freiberg
Corps (; plural ''corps'' ; from French , from the Latin "body") is a term used for several different kinds of organization. A military innovation by Napoleon I, the formation was first named as such in 1805. The size of a corps varies greatly, but from two to five divisions and anywhere from 40,000 to 80,000 are the numbers stated by the US Department of Defense. Within military terminology a corps may be: *an operational formation, sometimes known as a field corps, which consists of two or more divisions, such as the , later known as ("First Corps") of Napoleon I's ); *an administrative corps (or mustering) – that is a specialized branch of a military service (such as an artillery corps, a medical corps, or a force of military police) or; *in some cases, a distinct service within a national military (such as the United States Marine Corps). These usages often overlap. Corps may also be a generic term for a non-military organization, such as the US Peace Corps and E ...

Asimov's Biographical Encyclopedia Of Science And Technology
''Asimov's Biographical Encyclopedia of Science and Technology'' is a history of science by Isaac Asimov, written as the biographies of initially 1000 scientists and later with over 1500 entries. Organized chronologically, beginning with Imhotep (entry " ) and concluding with Stephen Hawking (entry "510), each biographical entry is numbered, allowing for easy cross-referencing of one scientist with another. Nearly every biographical sketch contains links to other biographies. For example, the article about John Franklin Enders 195has the sentence "Alexander Fleming's 077penicillin was available thanks to the work of Howard Florey 213and Ernst Boris Chain 306 . . ." This allows one to quickly refer to the articles about Fleming, Florey, and Chain. It includes scientists in all fields including biologists, chemists, astronomers, physicists, mathematicians, geologist, and explorers. The alphabetical list of biographical entries starts with ABBE, Cleveland 38and ends with ZWOR ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
19th-century German Chemists
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Gunpowder empires, Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under Colonialism, colonial rule. It was also marked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Discoverers Of Chemical Elements
Discovery is the act of detecting something new, or something previously unrecognized as meaningful. With reference to sciences and Discipline (academia), academic disciplines, discovery is the observation of new Phenomenon, phenomena, new actions, or new events and providing new reasoning to explain the knowledge gathered through such observations with previously acquired knowledge from abstract thought and everyday experiences. A discovery may sometimes be based on earlier discoveries, collaborations, or ideas. Some discoveries represent a radical breakthrough in knowledge or technology. New discoveries are acquired through various senses and are usually assimilated, merging with pre-existing knowledge and action (philosophy), actions. Questioning is a major form of human thought and interpersonal communication, and plays a key role in discovery. Discoveries are often made due to questions. Some discoveries lead to the invention of objects, processes, or techniques. A discover ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
