Konrad Zuse
Konrad Ernst Otto Zuse (; ; 22 June 1910 – 18 December 1995) was a German civil engineer, List of pioneers in computer science, pioneering computer scientist, inventor and businessman. His greatest achievement was the world's first programmable computer; the functional program-controlled Turing completeness, Turing-complete Z3 (computer), Z3 became operational in May 1941. Thanks to this machine and its predecessors, Zuse is regarded by some as the inventor and father of the modern computer. Zuse was noted for the S2 computing machine, considered the first process control computer. In 1941, he founded one of the earliest computer businesses, producing the Z4 (computer), Z4, which became the world's first commercial computer. From 1943 to 1945 he designed Plankalkül, the first high-level programming language. In 1969, Zuse suggested the concept of a digital physics, computation-based universe in his book (''Calculating Space''). Much of his early work was financed by his f ...

Z4 (computer)
The Z4 was arguably the world's first commercial digital computer, and is the oldest surviving programmable computer. It was designed, and manufactured by early computer scientist Konrad Zuse's company ''Zuse Apparatebau'', for an order placed by Henschel & Son, in 1942; though only partially assembled in Berlin, then completed in Göttingen in the Third Reich in April 1945, but not delivered before the defeat of Nazi Germany, in 1945. The Z4 was Zuse's final target for the Z3 (computer), Z3 design. Like the earlier Z2 (computer), Z2, it comprised a combination of mechanical memory and Electromechanics, electromechanical logic. The Z4 was used at the ETH Zurich from 1950 to 1955, also serving as the inspiration for the construction of the ERMETH, the first Swiss computer, created under the direction of ETH engineer Ambros Speiser. Construction The Z4 was very similar to the Z3 (computer), Z3 in its design but was significantly enhanced in a number of respects. The memory consis ...

Z3 (computer)
The Z3 was a German electromechanical computer designed by Konrad Zuse in 1938, and completed in 1941. It was the world's first working Computer programming, programmable, fully automatic digital computer. The Z3 was built with 2,600 relays, implementing a 22-bit Word (data type), word length that operated at a clock frequency of about 5–10 Hertz, Hz. Program code was stored on punched celluloid, film. Initial values were entered manually. The Z3 was completed in Berlin in 1941. It was not considered vital, so it was never put into everyday operation. Based on the work of the German aerodynamics engineer Hans Georg Küssner (known for the Küssner effect), a "Program to Compute a Complex Matrix" was written and used to solve wing flutter problems. Zuse asked the German government for funding to replace the relays with fully electronic switches, but funding was denied during World War II since such development was deemed "not war-important". The original Z3 was destroyed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kingdom Of Prussia
The Kingdom of Prussia (, ) was a German state that existed from 1701 to 1918.Marriott, J. A. R., and Charles Grant Robertson. ''The Evolution of Prussia, the Making of an Empire''. Rev. ed. Oxford: Clarendon Press, 1946. It played a significant role in the unification of Germany in 1871 and was a major constituent of the German Empire until its German Revolution of 1918–1919, dissolution in 1918. Although it took its name from the Prussia (region), region called Prussia, it was based in the Margraviate of Brandenburg. Its capital was Berlin. The list of monarchs of Prussia, kings of Prussia were from the House of Hohenzollern. The polity of Brandenburg-Prussia, predecessor of the kingdom, became a military power under Frederick William, Elector of Brandenburg, known as "The Great Elector". As a kingdom, Prussia continued its rise to power, especially during the reign of Frederick the Great, Frederick II "the Great".Horn, D. B. "The Youth of Frederick the Great 1712–30." ...

ERMETH
The ERMETH (''Elektronische Rechenmaschine der ETH'', German for Electronic Calculating Machine of the ETH) was one of the first computers in Europe and was developed and built by Eduard Stiefel and his team of the Seminar for Applied Mathematics, Institute for Applied Mathematics at the ETH Zurich between 1948 and 1956. It was in use until 1963 and is now displayed at the Museum of Communication Bern (Switzerland). Models Eduard Stiefel and his two senior assistants Heinz Rutishauser and Ambros Speiser were inspired by models in the USA and United Kingdom when developing the ERMETH. In 1949 Rutishauser and Speiser undertook study trips to Howard Aiken (Harvard University), John von Neumann (Princeton University) and to the University of Cambridge, which operated the EDSAC. In 1950, Stiefel rented for five years the only existing digital computer in continental Europe at that time, the Zuse Z4, completed by Konrad Zuse in 1945, for the ETH in order to gain experience with a cal ...

Process Control
Industrial process control (IPC) or simply process control is a system used in modern manufacturing which uses the principles of control theory and physical industrial control systems to monitor, control and optimize continuous Industrial processes, industrial production processes using control algorithms. This ensures that the industrial machines run smoothly and safely in factories and efficiently use energy to transform raw materials into high-quality finished products with reliable consistency while reducing Efficient energy use#Industry, energy waste and economic costs, something which could not be achieved purely by human manual control. In IPC, control theory provides the theoretical framework to understand system dynamics, predict outcomes and design control strategies to ensure predetermined objectives, utilizing concepts like feedback loops, stability analysis and controller design. On the other hand, the physical apparatus of IPC, based on automation technologies, cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-level Programming Language
A high-level programming language is a programming language with strong Abstraction (computer science), abstraction from the details of the computer. In contrast to low-level programming languages, it may use natural language ''elements'', be easier to use, or may automate (or even hide entirely) significant areas of computing systems (e.g. memory management), making the process of developing a program simpler and more understandable than when using a lower-level language. The amount of abstraction provided defines how "high-level" a programming language is. In the 1960s, a high-level programming language using a compiler was commonly called an ''autocode''. Examples of autocodes are COBOL and Fortran. The first high-level programming language designed for computers was Plankalkül, created by Konrad Zuse. However, it was not implemented in his time, and his original contributions were largely isolated from other developments due to World War II, aside from the language's influe ...

East Prussia
East Prussia was a Provinces of Prussia, province of the Kingdom of Prussia from 1772 to 1829 and again from 1878 (with the Kingdom itself being part of the German Empire from 1871); following World War I it formed part of the Weimar Republic's Free State of Prussia, until 1945. Its capital city was Königsberg (present-day Kaliningrad). East Prussia was the main part of the Prussia (region), region of Prussia along the southeastern Baltic Sea, Baltic Coast. The bulk of the ancestral lands of the Baltic Old Prussians were enclosed within East Prussia. During the 13th century, the native Prussians were conquered by the crusading Teutonic Knights. After the Northern Crusades, conquest the indigenous Balts were gradually converted to Christianity. Because of Germanization and colonisation over the following centuries, Germans became the dominant ethnic group, while Polish people, Poles and Lithuanians formed sizeable minorities. From the 13th century, the region of Prussia was part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Guardian
''The Guardian'' is a British daily newspaper. It was founded in Manchester in 1821 as ''The Manchester Guardian'' and changed its name in 1959, followed by a move to London.
