Walther Bauersfeld
Walther Bauersfeld (23 January 1879 – 28 October 1959) was a German engineer. Life He was employed by the Carl Zeiss Jena, who, on a suggestion by the German astronomer Max Wolf, started work on the first projection planetarium in 1912. This work was stopped by military needs during World War I, but resumed after the war. Bauersfeld completed the first planetarium, known as the Zeiss I model in 1923, and it was initially placed on the roof of a Zeiss building in the corporate headquarters town of Jena. This model projected 4,900 stars, and was limited to showing the sky only from Jena's latitude. Subsequently, Bauersfeld developed the Model 2 with 8,956 stars, and full latitude capability. Over a dozen were installed before World War II again suspended planetarium work. These inter-war planetariums were constructed in Berlin and Düsseldorf in Germany, as well as Rome, Paris, Chicago, Los Angeles and New York. The Zeiss I planetarium in Jena is also considered the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geodesic Dome
A geodesic dome is a hemispherical thin-shell structure (lattice-shell) based on a geodesic polyhedron. The triangular elements of the dome are structurally rigid and distribute the structural stress throughout the structure, making geodesic domes able to withstand very heavy loads for their size. History The first geodesic dome was designed after World War I by Walther Bauersfeld, chief engineer of the Carl Zeiss optical company, for a planetarium to house his planetarium projector. An initial, small dome was patented and constructed by the firm of Dykerhoff and Wydmann on the roof of the Zeiss plant in Jena, Germany. A larger dome, called "The Wonder of Jena", opened to the public in July 1926. Twenty years later, Buckminster Fuller coined the term "geodesic" from field experiments with artist Kenneth Snelson at Black Mountain College in 1948 and 1949. Although Fuller was not the original inventor, he is credited with the U.S. popularization of the idea for which he rece ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Engineers From Berlin
Engineers, as practitioners of engineering, are professionals who Invention, invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year Bachelor of Engineering, bachelor's degree in an engineering discipline, or in some jurisdictions, a Master of Engineering, master's degree in an engineering disciplin ...

1553 Bauersfelda
1553 Bauersfelda, provisional designation , is a stony Koronian asteroid from the outer regions of the asteroid belt, approximately 13 kilometers in diameter. It was discovered on 13 January 1940, by astronomer Karl Reinmuth at the Heidelberg Observatory in southwest Germany. The asteroid was named after German engineer Walther Bauersfeld. Orbit and classification Based on its orbital parameters, ''Bauersfelda'' is a member of the Koronis family (), a very large outer asteroid family with nearly co-planar ecliptical orbits. However, ''Bauersfelda'' turns out to be a non-family asteroid from the main belt's background population when applying the hierarchical clustering method to its proper orbital elements. ''Bauersfelda'' orbits the Sun in the outer main-belt at a distance of 2.6–3.2 AU once every 4 years and 11 months (1,810 days). Its orbit has an eccentricity of 0.10 and an inclination of 3 ° with respect to the ecliptic. The body's observation arc begins with its ...

East Germany
East Germany, officially the German Democratic Republic (GDR; german: Deutsche Demokratische Republik, , DDR, ), was a country that existed from its creation on 7 October 1949 until its dissolution on 3 October 1990. In these years the state was a part of the Eastern Bloc in the Cold War. Commonly described as a communist state, it described itself as a socialist "workers' and peasants' state".Patrick Major, Jonathan Osmond, ''The Workers' and Peasants' State: Communism and Society in East Germany Under Ulbricht 1945–71'', Manchester University Press, 2002, Its territory was administered and occupied by Soviet forces following the end of World War II—the Soviet occupation zone of the Potsdam Agreement, bounded on the east by the Oder–Neisse line. The Soviet zone surrounded West Berlin but did not include it and West Berlin remained outside the jurisdiction of the GDR. Most scholars and academics describe the GDR as a totalitarian dictatorship. The GDR was establish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Werner Von Siemens Ring
The Werner von Siemens Ring (in German orthography, Werner-von-Siemens-Ring) is one of the highest awards for technical sciences in Germany. It has been awarded from 1916 to 1941 and since 1952 about every three years by the foundation ''Stiftung Werner-von-Siemens-Ring''. The foundation was established on 13 December 1916 on the occasion of the 100th anniversary of the birth of Werner von Siemens. It is located in Berlin and is traditionally managed by the '' Deutscher Verband Technisch-Wissenschaftlicher Vereine'' (DVT) (English: German Federation of Technical and Scientific Associations). Before 1960, the name of the award had been simply Siemens Ring (German Siemens-Ring or Siemensring). The award is presented as a golden ring with emeralds and rubies depicting the leaves and fruit of laurel, placed in an individually crafted cassette carrying the portrait of Werner von Siemens and the dedication to the recipient. According to the statutes, patron of the foundation council is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elliott Cresson Medal
The Elliott Cresson Medal, also known as the Elliott Cresson Gold Medal, was the highest award given by the Franklin Institute. The award was established by Elliott Cresson, life member of the Franklin Institute, with $1,000 granted in 1848. The endowed award was to be "for some discovery in the Arts and Sciences, or for the invention or improvement of some useful machine, or for some new process or combination of materials in manufactures, or for ingenuity skill or perfection in workmanship." The medal was first awarded in 1875, 21 years after Cresson's death. The Franklin Institute continued awarding the medal on an occasional basis until 1998 when they reorganized their endowed awards under one umbrella, The Benjamin Franklin Awards. A total of 268 Elliott Cresson Medals were given out during the award's lifetime.
