Freiberg
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. P ...

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. Its focus is on exploration, mining & extraction, processing, and recycling of natural resources & scrap, as well as developing new materials. Today, it's the oldest university of mining and metallurgy in the world. History Before 1945 The institution was established in 1765, during the Age of Enlightenment, by Prince Francis Xavier of Saxony based on plans by Friedrich Wilhelm von Oppel and Friedrich Anton von Heynitz, then called ''Kurfürstlich-Sächsische Bergakademie zu Freiberg'' (by 1806: ''Königlich-Sächsische Bergakademie zu Freiberg''). Its main purpose was the education of highly skilled miners and scientists in fields connected to mining and metallurgy.

Lake Guatavita
Lake Guatavita (Spanish: ''Laguna Guatavita'') is located in the Cordillera Oriental of the Colombian Andes in the municipality of Sesquilé in the Almeidas Province, Cundinamarca department of Colombia, northeast of Bogotá, the capital of Colombia. The lake is circular and has a surface area of 19.8 hectares. The earlier theories of the crater's origin being a meteorite impact, volcanic cinder, or limestone sinkhole are now discredited. The most likely explanation is that it resulted from the dissolution of underground salt deposits from an anticline, resulting in a kind of sinkhole. There are hot springs nearby in the municipality of Sesquilé, which means "hot water" in the now-extinct language of Chibcha, once spoken by the local indigenous people, the Muisca. Spanish colonizers and Conquistadors knew about the existence of a sacred lake in the Eastern Ranges of the Andes possibly as early as 1531. The lake was associated with indigenous rituals involving gold. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salt Mining
Salt mining extracts natural salt deposits from underground. The mined salt is usually in the form of halite (commonly known as rock salt), and extracted from evaporite formations. History Before the advent of the modern internal combustion engine and earth-moving equipment, mining salt was one of the most expensive and dangerous of operations because of rapid dehydration caused by constant contact with the salt (both in the mine passages and scattered in the air as salt dust) and of other problems caused by accidental excessive sodium intake. Salt is now plentiful, but until the Industrial Revolution, it was difficult to come by, and salt was often mined by slaves or prisoners. Life expectancy for the miners was low. Ancient China was among the earliest civilizations in the world with cultivation and trade in mined salt. They first discovered natural gas when they excavated rock salt. The Chinese writer, poet, and politician Zhang Hua of the Jin dynasty wrote in his book ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Before he turned ten, he lost both parents and lived in several households. Bolívar was educated abroad and lived in Spain, as was common for men of upper-class families in his day. While living in Madrid from 1800 to 1802, he was introduced to Enlightenment philosophy and met his future wife María Teresa Rodríguez del Toro y Alaysa. After returning to Venezuela, in 1803 del Toro contracted yellow fever and died. From 1803 to 1805, Bolívar embarked on a grand tour that ended in Rome, where he swore t ...

The Liberator Of South America
''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic p ...

Bolívar's Campaign To Liberate New Granada
Bolívar's campaign to liberate New Granada was part of the Colombian and Venezuelan wars of independence and was one of the many military campaigns fought by Simón Bolívar. Bolívar's victory in New Granada (today, Colombia, Venezuela, Ecuador and Panama) secured the eventual independence of northern South America. It provided Bolívar with the economic and human resources to complete his victory over the Spanish in Venezuela and Colombia. Bolívar's attack on New Granada is considered one of the most daring in military history, compared by contemporaries and some historians to Napoleon's crossing of the Alps in 1800 and José San Martín's Crossing of the Andes in 1817. Background During the years 1815 and 1816, Spain had reconquered most of New Granada after five years of de facto and official independence. By 1817, Bolívar had set up his headquarters in the Orinoco region in southern Venezuela. It was an area from which the Spaniards could not easily oust him. There ...

Lead
Lead is a chemical element with the Symbol (chemistry), symbol Pb (from the Latin ) and atomic number 82. It is a heavy metals, heavy metal that is density, denser than most common materials. Lead is Mohs scale of mineral hardness#Intermediate hardness, soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable nuclide, stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and base (chemistry), bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
