Ambros Speiser
Ambrosius Paul Speiser (13 November 1922, in Basel – 10 May 2003, in Aarau) was a Swiss engineer and scientist. He led the development of the first Swiss computer. Speiser studied electrotechnology at Eidgenössische Technische Hochschule (ETH), where in 1948 he earned his diplom in communications engineering. In 1949, Eduard Stiefel sent Heinz Rutishauser and Speiser to study in Harvard under Howard H. Aiken and in Princeton under John von Neumann; Rutishauser and Speiser became acquainted with the Harvard Mark III and the IAS machine. In 1950, the Institut für angewandte Mathematik (Institute for Applied Mathematics, founded in 1948) of ETH could acquire the Zuse Z4, but there were no other commercially available electronic computers which were suitable for scientific applications. This led the Swiss to the idea of developing their own computer. Under Speiser's technical direction between 1950 and 1955, Switzerland's first electronic calculating machine, ERMETH, originat ...

Photo Of Ambros Speiser Giving A Lecture
A photograph (also known as a photo, image, or picture) is an image created by light falling on a photosensitive surface, usually photographic film or an electronic image sensor, such as a CCD or a CMOS chip. Most photographs are now created using a smartphone/ camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and practice of creating such images is called photography. Etymology The word ''photograph'' was coined in 1839 by Sir John Herschel and is based on the Greek φῶς (''phos''), meaning "light," and γραφή (''graphê''), meaning "drawing, writing," together meaning "drawing with light." History The first permanent photograph, a contact-exposed copy of an engraving, was made in 1822 using the bitumen-based " heliography" process developed by Nicéphore Niépce. The first photographs of a real-world scene, made using a camera obscura, followed a few years later at Le G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zuse Z4
The Z4 was arguably the world's first commercial digital 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, and not delivered by the defeat of Nazi Germany, in 1945. The Z4 was Zuse's final target for the Z3 design. Like the earlier Z2, it comprised a combination of mechanical memory and electromechanical logic, so was not a true electronic computer. Construction The Z4 was very similar to the Z3 in its design but was significantly enhanced in a number of respects. The memory consisted of 32-bit rather than 22-bit floating point words. The Program Construction Unit (''Planfertigungsteil'') punched the program tapes, making programming and correcting programs for the machine much easier by the use of symbolic operations and memory cells. Numbers were entered and output as decimal floating-poin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Economiesuisse
Economiesuisse is a Swiss corporate union, composed of the fusion of the Union suisse du commerce et de l'industrie ("Swiss union of commerce and industry") or Vorort, and of the Société pour le développement de l'économie suisse ("society for development of Swiss economy"). History The USCI was founded in 1870, following a string of workers' strikes and demonstrations. In 1882, it was renamed Vorort. It aimed at favouring the interests of business owners. From 1870 to 1882, the USCI lacked a permanent committee, and each member canton Canton may refer to: Administrative division terminology * Canton (administrative division), territorial/administrative division in some countries, notably Switzerland * Township (Canada), known as ''canton'' in Canadian French Arts and ente ... would preside in rotation. From 1882, the USCI was re-organised around a nine-member direction organ, the Vorort, seating in Zurich. From 1931, the chambre Suisse du commerce, another organ ...

Computer Science
Computer science is the study of computation, automation, and information. Computer science spans theoretical disciplines (such as algorithms, theory of computation, information theory, and automation) to Applied science, practical disciplines (including the design and implementation of Computer architecture, hardware and Computer programming, software). Computer science is generally considered an area of research, academic research and distinct from computer programming. Algorithms and data structures are central to computer science. The theory of computation concerns abstract models of computation and general classes of computational problem, problems that can be solved using them. The fields of cryptography and computer security involve studying the means for secure communication and for preventing Vulnerability (computing), security vulnerabilities. Computer graphics (computer science), Computer graphics and computational geometry address the generation of images. Progr ...

Baden, Switzerland
Baden (German for "baths"), sometimes unofficially, to distinguish it from other Badens, called Baden bei Zürich ("Baden near Zürich") or Baden im Aargau ("Baden in the Aargau"), is a town and a municipality in Switzerland. It is the main town or seat of the district of Baden in the canton of Aargau. Located northwest of Zürich in the Limmat Valley (german: Limmattal) mainly on the western side of the river Limmat, its mineral hot springs have been famed since at least the Roman era. Its official language is (the Swiss variety of Standard) German, but the main spoken language is the local Alemannic Swiss-German dialect. the town had a population of over 19,000. Geography Downtown Baden is located on the left bank of the river Limmat in its eponymous valley. Its area is divided into the Kappelerhof, Allmend, Meierhof, and Chrüzliberg. In 1962, Baden also absorbed the adjacent village of Dättwil. On the right bank of the river is the village of Ennetbaden, former ...

Brown, Boveri & Cie
Brown, Boveri & Cie. (Brown, Boveri & Company; BBC) was a Swiss group of electrical engineering companies. It was founded in Zürich, in 1891 by Charles Eugene Lancelot Brown and Walter Boveri who worked at the Maschinenfabrik Oerlikon. In 1970 BBC took over the Maschinenfabrik Oerlikon. In 1988 it merged with ASEA to form ABB. Early History of BBC Brown Boveri BBC Brown Boveri was established in 1891. The company was one of only a few multinational corporations to operate subsidiaries that were larger than the parent company. Because of the limitations of the Swiss domestic market, Brown Boveri established subsidiaries throughout Europe relatively early in its history, and at times had difficulty maintaining managerial control over some of its larger operating units. The merger with ASEA, a company which was praised for its strong management, was expected to help Brown Boveri reorganize and reassert control over its vast international network.

Rüschlikon
Rüschlikon is a municipality in the district of Horgen in the canton of Zürich in Switzerland. It is located on the west shore of Lake Zürich. Coat of arms Its coat of arms features a white shield showing a red rose with a yellow center and a green two-leaved stem. History Earliest archaeological findings are grave mounds from the early Iron Age Hallstatt culture (800-450BC) on the Zimmerberg mountain. (German) retrieved 12 December 2013 The name of Rüschlikon is Alemannic and first appears in documents around 1153 as ''Ruoslinchoven''. In the early 1980s, Rüschlikon blocked off many of the smaller side streets from Thalwil so that traffic between Zürich and Thalwil would be unable to use them. The Swiss Re Centre for Global Dialogue is based in Rüschlikon. The centre is built in the grounds of the Villa Bodmer, which was owned by the Swiss industrialist Karl Martin Leonhard Bodmer. The CEO of commodities company Glencore, Ivan Glasenberg, is a resident of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
