Silver mining is the extraction of silver by mining. Silver is a precious metal and holds high economic value. Because silver is often found in intimate combination with other metals, its extraction requires the use of complex technologies. In 2008, approximately 25,900 metric tons of silver were consumed worldwide, most of which came from mining. Silver mining has a variety of effects on the environment, humans, and animals.

The University of Freiburg (colloquially German: Uni Freiburg), officially the Albert Ludwig University of Freiburg (German: Albert-Ludwigs-Universität Freiburg), is a public research university located in Freiburg im Breisgau, Baden-Württemberg, Germany. The university was founded in 1457 by the Habsburg dynasty as the second university in Austrian-Habsburg territory after the University of Vienna. Today, Freiburg is the fifth-oldest university in Germany, with a long tradition of teaching the humanities, social sciences and natural sciences and technology and enjoys a high academic reputation both nationally and internationally. The university is made up of 11 faculties and attracts students from across Germany as well as from over 120 other countries. Foreign students constitute about 18.2% of total student numbers.

The University of Freiburg has been associated with figures such as Hannah Arendt, Rudolf Carnap, David Daube, Johann Eck, Hans-Georg Gadamer, Friedrich Hayek, Martin Heidegger, Edmund Husserl, Herbert Marcuse, Friedrich Meinecke, Edith Stein, Paul Uhlenhuth, Max Weber and Ernst Zermelo. As of October 2020, 22 Nobel laureates are affiliated with the University of Freiburg as alumni, faculty or researchers, and 15 academics have been honored with the highest German research prize, the Gottfried Wilhelm Leibniz Prize, while working at the university.

Baden-Württemberg (/ˌbɑːdən ˈvɜːrtəmbɜːrɡ/ BAH-dən VURT-əm-burg; German: [ˌbaːdn̩ ˈvʏʁtəmbɛʁk] ), commonly shortened to BW or BaWü, is a German state (Land) in Southwest Germany, east of the Rhine, which forms the southern part of Germany's western border with France. With more than 11.07 million inhabitants as of 2019 across a total area of nearly 35,752 km (13,804 sq mi), it is the third-largest German state by both area (behind Bavaria and Lower Saxony) and population (behind North Rhine-Westphalia and Bavaria). The largest city in Baden-Württemberg is the state capital of Stuttgart, followed by Mannheim and Karlsruhe. Other major cities are Freiburg im Breisgau, Heidelberg, Heilbronn, Konstanz, Pforzheim, Reutlingen, Tübingen, and Ulm.

Modern Baden-Württemberg includes the historical territories of Baden, Prussian Hohenzollern, and Württemberg. Baden-Württemberg became a state of West Germany in April 1952 through the merger of South Baden, Württemberg-Baden, and Württemberg-Hohenzollern. These states had been created by the Allies as they separated traditional states into occupation zones after World War II.

The Agri Decumates or Decumates Agri ("Decumatian Fields") were a region of the Roman Empire's provinces of Germania Superior and Raetia, covering the Black Forest, Swabian Jura, and Franconian Jura areas between the Rhine, Main, and Danube rivers, in present southwestern Germany, including present Frankfurt, Stuttgart, Freiburg im Breisgau, and Weißenburg in Bayern.

The only ancient reference to the name comes from Tacitus' book Germania (chapter 29). However, the later geographer Claudius Ptolemy does mention "the desert of the Helvetians" in this area.

K-Groups (German: Kommunistische Gruppen, lit. 'Communist Groups') is a term referring to various small, Maoist organizations and political parties that sprang up in West Germany at the end of the 1960s, following the collapse of the Socialist German Students' Union (SDS), and general collapse of the West German student movement. K-Groups played a particularly important role within the New Left in West Germany during the first half of the 1970s. The term "K-Group" was used primarily by competing left-wing groups and in the media. It served as a collective term for the numerous, often fiercely divided groups and alluded to their shared self-image as communist cadre organizations.

Various organizations referred to as K-Groups included the Communist Party of Germany/Marxists–Leninists (KPD/ML), the Communist Party of Germany (Organizational Structure) (KPD-AO), the Communist League (KB), the Communist League of West Germany (KBW), the Communist Workers Union of Germany (KABD), and the Bavarian-based Workers League for the Reconstruction of the KPD [de] (AB).

Cast stone or reconstructed stone is a refined artificial stone, a form of precast concrete. It is used as a building material to simulate natural-cut masonry in architectural features such as facings and trim; for statuary; and for garden ornaments. It may replace natural building stones including limestone, brownstone, sandstone, bluestone, granite, slate, and travertine. Cast stone can be made from white or grey cements, manufactured or natural sands, crushed stone or natural gravels, and can be coloured with mineral colouring pigments. It is cheaper and more uniform than natural stone, and allows transporting the bulk materials and casting near the place of use, which is cheaper than transporting and carving very large pieces of stone.

Sonnenschiff (lit. 'sun ship') is a large integrated office and retail building in Freiburg im Breisgau, Germany. It was built in 2004 in the city's Vauban quarter as part of the Solar Settlement at Schlierberg. Sonnenschiff was designed by the architect Rolf Disch (who also built the Heliotrope building) and generates four times more energy than it uses.

As a whole this building produces more energy than it consumes per year and utilizes the most up-to-date building technology. Some aspects that make this building particular are its vacuum insulated walls, ventilation with 95% heat recovery, triple paned windows and its energy façade.

Rolf Disch is a German architect, solar energy pioneer and environmental activist. Born in Freiburg im Breisgau, Germany, Disch has dedicated particular focus to regional renewable and sustainable energy.

As head of his own architecture firm, Rolf Disch Solar Architecture, Disch is committed to advancing Germany's incorporation of solar energy generation into residential, retail, and commercial building and design. In 1994, Rolf Disch built the Heliotrope in Freiburg which was the world’s first home to create more energy than it uses, as it physically rotates with the sun to maximize its solar intake. Disch then developed the concept PlusEnergy, simply making it a permanent goal for his buildings to produce more energy than they consume in order to sell the surplus solar energy back into the grid for profit.

The Heliotrope is an environmentally friendly housing project by German architect Rolf Disch. There are three such buildings in Germany. The first experimental version was built in 1994 as the architect's home in Freiburg im Breisgau, while the other two were used as exhibition buildings for the Hansgrohe company in Offenburg and a dentist's lab in Hilpoltstein in Bavaria.

Several different energy generation modules are used in the building including a 603 sq ft (56.0 m) dual-axis solar photovoltaic tracking panel, a geothermal heat exchanger, a combined heat and power unit (CHP) and solar-thermal balcony railings to provide heat and warm water. These innovations along with the favorable insulation of the residence allows the Heliotrope to capture anywhere between four and six times its energy usage depending on the time of year. The Heliotrope is also fitted with a grey-water cleansing system and built-in natural waste composting.

Günther Osche (also spelled Guenther Osche, born 7 August 1926 in Neustadt an der Weinstraße, died 2 February 2009 in Freiburg im Breisgau) was a German evolutionary biologist, ecologist and parasitologist.

He started his career with a research on nematodes having Hans-Jürgen Stammer (1899-1968) as his scientific supervisor. He is known to have raised the name Rhabditides elegans in the subgenus Caenorhabditis in 1952 in the history of the naming of the model worm Caenorhabditis elegans.
