Führerbunker
The ''Führerbunker'' () was an air raid shelter located near the Reich Chancellery in Berlin, Germany. It was part of a subterranean bunker complex constructed in two phases in 1936 and 1944. It was the last of the Führer Headquarters (''Führerhauptquartiere'') used by Adolf Hitler during World War II. Hitler took up residence in the ''Führerbunker'' on 16 January 1945, and it became the centre of the Nazi regime until the last week of World War II in Europe. Hitler married Eva Braun there on 29 April 1945, less than 40 hours before they committed suicide. After the war, both the old and new Chancellery buildings were levelled by the Soviets. The underground complex remained largely undisturbed until 1988–89, despite some attempts at demolition. The excavated sections of the old bunker complex were mostly destroyed during reconstruction of that area of Berlin. The site remained unmarked until 2006, when a small plaque was installed with a schematic diagram. Some ...

Bauhaus
The Staatliches Bauhaus (), commonly known as the Bauhaus (), was a German art school operational from 1919 to 1933 that combined crafts and the fine arts.Oxford Dictionary of Art and Artists (Oxford: Oxford University Press, 4th edn., 2009), , pp. 64–66 The school became famous for its approach to design, which attempted to unify individual artistic vision with the principles of mass production and emphasis on function. The Bauhaus was founded by architect Walter Gropius in Weimar. It was grounded in the idea of creating a Gesamtkunstwerk ("comprehensive artwork") in which all the arts would eventually be brought together. The Bauhaus style later became one of the most influential currents in modern design, modernist architecture, and architectural education. The Bauhaus movement had a profound influence upon subsequent developments in art, architecture, graphic design, interior design, industrial design, and typography.

Nuclear Power Plant
A nuclear power plant (NPP) is a thermal power station in which the heat source is a nuclear reactor. As is typical of thermal power stations, heat is used to generate steam that drives a steam turbine connected to a generator that produces electricity. , the International Atomic Energy Agency reported there were 422 nuclear power reactors in operation in 32 countries around the world, and 57 nuclear power reactors under construction. Nuclear plants are very often used for base load since their operations, maintenance, and fuel costs are at the lower end of the spectrum of costs. However, building a nuclear power plant often spans five to ten years, which can accrue to significant financial costs, depending on how the initial investments are financed. Nuclear power plants have a carbon footprint comparable to that of renewable energy such as solar farms and wind farms, and much lower than fossil fuels such as natural gas and brown coal. Despite some spectacu ...

Public Company
A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listed company), which facilitates the trade of shares, or not ( unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states, and therefore have associations and formal designations which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation (though a corporation need not be a public company), in the United Kingdom it is usually a public limited company (plc ...
