Hans Georg Küssner
Hans Georg Küssner (14 September 190021 March 1984) was a German physicist and aeronautical scientist known for his work in the field of aeroelasticity. Work Hans Georg Küssner was born on 14 September 1900 in Bartenstein, then part of the East Prussian district of in the German Reich. Küssner studied at the Technical University of the Free City of Danzig (now Gdańsk University of Technology) and received his doctorate in 1928 with his dissertation "Das wirtschaftliche Ozeanflugzeug" under Viktor Rembold. In the same year he moved to the German Research Institute for Aviation in Berlin, where he worked on the aircraft problem of flutter, which was reflected in a large number of publications. In 1934, Küssner moved to the Aerodynamics Research Institute in Göttingen. In 1936 he formulated the Küssner function to describe the unsteady effect on wings caused by turbulence. In 1939, Küssner was appointed head of the "Institute for Transient Processes". Here he ach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of Phenomenon, phenomena, and usually frame their understanding in mathematical terms. They work across a wide range of Physics#Research fields, research fields, spanning all length scales: from atom, sub-atomic and particle physics, through biological physics, to physical cosmology, cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: Experimental physics, experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and Theoretical physics, theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1900 Births
As of March 1 ( O.S. February 17), when the Julian calendar acknowledged a leap day and the Gregorian calendar did not, the Julian calendar fell one day further behind, bringing the difference to 13 days until February 28 ( O.S. February 15), 2100. Summary Political and military The year 1900 was the end of the 19th century and the beginning of the 20th century. Two days into the new year, the U.S. Secretary of State John Hay announced the Open Door Policy regarding China, advocating for equal access for all nations to the Chinese market.

Continuum Mechanics
Continuum mechanics is a branch of mechanics that deals with the deformation of and transmission of forces through materials modeled as a ''continuous medium'' (also called a ''continuum'') rather than as discrete particles. Continuum mechanics deals with ''deformable bodies'', as opposed to rigid bodies. A continuum model assumes that the substance of the object completely fills the space it occupies. While ignoring the fact that matter is made of atoms, this provides a sufficiently accurate description of matter on length scales much greater than that of inter-atomic distances. The concept of a continuous medium allows for intuitive analysis of bulk matter by using differential equations that describe the behavior of such matter according to physical laws, such as mass conservation, momentum conservation, and energy conservation. Information about the specific material is expressed in constitutive relationships. Continuum mechanics treats the physical properties of ...

Max Planck Institute For Flow Research
The Max Planck Institute for Dynamics and Self-Organization in Göttingen, Germany, is a research institute for investigations of complex non-equilibrium systems, particularly in physics and biology. Its founding history goes back to Ludwig Prandtl who in 1911 requested a Kaiser Wilhelm Institute to be founded for the investigation of aerodynamics and hydrodynamics. As a first step the ''Aeronautische Versuchsanstalt'' (now the DLR) was established in 1915 and then finally the Kaiser Wilhelm Institute for Flow Research was established in 1924. In 1948 it became part of the Max Planck Society. The Max Planck Society was founded in this institute. In 2003 it was renamed to Max Planck Institute for Dynamics and Self-Organization. It is one of 80 institutes in the Max Planck Society (Max Planck Gesellschaft). History The early history of the Max Planck Institute for Dynamics and Self-Organization is closely linked to the work of the famous physicist Ludwig Prandtl. Prandtl is re ...

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 programmable, fully automatic digital computer. The Z3 was built with 2,600 relays, implementing a 22-bit word length that operated at a clock frequency of about 5–10 Hz. Program code was stored on punched 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 on 21 December 1943 during an Allied bombardment of Ber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
