Mittelwerk ([ˈmɪtl̩.vɛʁk]; German for "Central Works") was a German World War II factory built underground in the Kohnstein to avoid Allied bombing. It used slave labor from the Mittelbau-Dora concentration camp to produce V-2 ballistic missiles, V-1 flying bombs, and other weapons. Mittelwerk GmbH On the night of 17/18 August 1943, RAF bombers carried out Operation Hydra against the Peenemünde Army Research Center where V-2 development and production was being carried out. On 19 October 1943, the German limited company Mittelwerk GmbH was issued War Contract No. 0011-5565/43 by General Emil Leeb, head of the Army Weapons Office, for 12,000 A-4 missiles at 40,000 Reichsmarks each.Mittelwerk GmbH also headed sites for V-2 rocket development and testing at Schlier (Project Zement) and Lehesten. Beginning in May 1944, Georg Rickhey was the Mittelwerk general manager, Albin Sawatzki was the Mittelwerk technical director over both Arthur Rudolph's Technical Division...

Peanut butter is a food paste or spread made from ground, dry-roasted peanuts. It commonly contains additional ingredients that modify the taste or texture, such as salt, sweeteners, or emulsifiers. Consumed in many countries, it is the most commonly used of the nut butters, a group that also includes cashew butter and almond butter (though peanuts are not nuts, peanut butter is culinarily considered a nut butter). Peanut butter is a nutrient-rich food containing high levels of protein, several vitamins, and dietary minerals. It is typically served as a spread on bread, toast, or crackers, and used to make sandwiches (notably the peanut butter and jelly sandwich). It is also used in a number of breakfast dishes and desserts, such as granola, smoothies, crepes, cookies, brownies, or croissants. History The earliest references to peanut butter can be traced to Aztec and Inca civilizations, who ground roasted peanuts into a paste. However, several people can be credited with the invention of modern peanut butter and the processes involved in making it. The US National Peanut Board credits...

Thucydides (; Ancient Greek: Θουκυδίδης, romanized: Thoukudídēs; c. 460 – c. 400 BC) was an Athenian historian and general. His History of the Peloponnesian War recounts the fifth-century BC war between Sparta and Athens until the year 411 BC. Thucydides has been dubbed the father of "scientific history" by those who accept his claims to have applied strict standards of impartiality and evidence-gathering and analysis of cause and effect, without reference to intervention by the gods, as outlined in his introduction to his work.He also has been called the father of the school of political realism, which views the political behavior of individuals and the subsequent outcomes of relations between states as ultimately mediated by, and constructed upon, fear and self-interest. His text is still studied at universities and military colleges worldwide. The Melian dialogue is regarded as...

Life Among the Paiutes: Their Wrongs and Claims is a book that was written by Sarah Winnemucca in 1883. It is both an autobiographic memoir and a history of the Paiute people during their first forty years of contact with European Americans. It is considered the "first known autobiography written by a Native American woman." Anthropologist Omer Stewart described it as "one of the first and one of the most enduring ethnohistorical books written by an American Indian," frequently cited by scholars. Winnemucca wrote Life Among the Paiutes: Their Wrongs and Claims while she was doing lectures on the East Coast of the United States, advocating in the English language for the rights of the Northern Paiute people, and she was assisted in the funding, editing, and publishing of the book by sisters Elizabeth Palmer Peabody and Mary Peabody Mann.Political Intentions Winnemucca had been working as an advocate, diplomat, and interpreter for the Paiute people, utilizing her ability to speak English, since 1866. Her frequent interactions with and work alongside among the Anglo-Americans empowered her to act as a "politically...

Angry Penguins was an art and literary journal founded in 1940 by surrealist poet Max Harris, at the age of 18. Originally based in Adelaide, the journal moved to Melbourne in 1942 once Harris joined the Heide Circle, a group of avant-garde painters and writers who stayed at Heide, a property owned by art patrons John and Sunday Reed. Angry Penguins subsequently became associated with, and stimulated, an art movement that would later be known by the same name. Key figures of the movement include Sidney Nolan, Arthur Boyd, Joy Hester and Albert Tucker. Origins and ethos Angry Penguins was a magazine first published in the South Australian capital of Adelaide. The title is derived from a phrase in Harris' poem "Mithridatum of Despair": "as drunks, the angry penguins of the night", and its use as a magazine title was suggested to Harris by C. R. Jury. The magazine's main Adelaide rival was the Jindyworobaks, a nationalist and anti-modernist literary movement promoting Indigenous Australian culture and the Australian bush ballad tradition. According to Angry Penguins...

Moringa oleifera is a fast-growing, drought-resistant tree of the family Moringaceae, native to the Indian subcontinent. Common names include moringa, drumstick tree (from the long, slender, triangular seed-pods), horseradish tree (from the taste of the roots, which resembles horseradish), and ben oil tree or benzolive tree.It is widely cultivated for its young seed pods and leaves, used as vegetables and for traditional herbal medicine. It is also used for water purification. Although listed as an invasive species in several countries, M. oleifera has "not been observed invading intact habitats or displacing native flora", so "should be regarded at present as a widely cultivated species with low invasive potential." Description M. oleifera is a fast-growing, deciduous tree that can reach a height of 10–12 metres (33–39 feet) and trunk diameter of 45 centimetres (18 inches). The bark has a whitish-gray color and is surrounded by thick cork. Young shoots have purplish or greenish-white, hairy bark....

Earth's outer core is a fluid layer about 2,260 km (1,400 mi) thick, composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. The outer core begins approximately 2,889 km (1,795 mi) beneath Earth's surface at the core-mantle boundary and ends 5,150 km (3,200 mi) beneath Earth's surface at the inner core boundary. Properties Unlike Earth's solid, inner core, its outer core is liquid. Evidence for a fluid outer core includes seismology which shows that seismic shear-waves are not transmitted through the outer core. Although having a composition similar to Earth's solid inner core, the outer core remains liquid as there is not enough pressure to keep it in a solid state. Seismic inversions of body waves and normal modes constrain the radius of the outer core to be 3483 km with an uncertainty of 5 km, while that of the inner core is 1220±10 km.: 94 Estimates for the temperature of the outer core are about 3,000–4,500 K (2,700–4,200 °C; 4,900–7,600 °F) in its outer region and 4,000–8,000 K (3,700–7,700...

The Directorate of Research and Civil Affairs (DORCA) was a mysterious and difficult-to-categorise think tank and possibly intelligence organisation within the Australian Army during World War II.Set up and headed by the charismatic Alf Conlon, the Directorate's alumni had a huge influence over Australia and the Pacific region post-WWII, especially through the Australian School of Pacific Administration (ASOPA).DORCA has been described as mysterious, odd ball, bohemian. It is difficult, if not impossible to categorise, having clearly involved at least in some sense in intelligence work. That it morphed into ASOPA after the war gives no real insight into its wartime activities. When formed in February 1943, the Directorate was made part of Military Intelligence, with Conlon reporting directly to General Blamey, commander-in-chief of the Australian Military Forces. Some of the work achieved during its short, wartime life included: making good the shortfall of no adequate military maps for the Northern Territory; finding substitute sources for quinine when Australia’s quinine suppliers came under Japanese control; preparing...

A phonograph record (also known as a gramophone record, especially in British English), a vinyl record, or simply a record, is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the periphery and ends near the center of the disc. At first, the discs were commonly made from shellac, with earlier records having a fine abrasive filler mixed in. Starting in the 1940s polyvinyl chloride became common, hence the common use of the word vinyl. The phonograph record was the primary medium used for music reproduction throughout the 20th century. It had co-existed with the phonograph cylinder from the late 1880s and had effectively superseded it by around 1912. Records retained the largest market share even when new formats such as the compact cassette were mass-marketed. By the 1980s, digital media, in the form of the compact disc, had gained a larger market share, and the record left the mainstream in 1991. Since the 1990s, records continue to be manufactured and sold on a smaller scale, and during the 1990s and early 2000s were commonly...

Cobalt-60 (60Co) is a synthetic radioactive isotope of cobalt with a half-life of 5.2713 years.: 39  It is produced artificially in nuclear reactors. Deliberate industrial production depends on neutron activation of bulk samples of the monoisotopic and mononuclidic cobalt isotope 59Co. Measurable quantities are also produced as a by-product of typical nuclear power plant operation and may be detected externally when leaks occur. In the latter case (in the absence of added cobalt) the incidentally produced 60...
