Hans G. Hornung
Hans G. Hornung is an emeritus C. L. "Kelly" Johnson Professor of Aeronautics and Director of the Guggenheim Aeronautical Laboratory of the California Institute of Technology (GALCIT). He received his bachelor (1960) and master (1962) degrees from the University of Melbourne and his Ph.D. degree (1965) in Aeronautics from Imperial College, London. He worked in the Aeronautical Research Laboratories, Melbourne (1962–63, and 1965–1967), and in the Physics Department of the Australian National University (1967–1980), with a sabbatical year as a Humboldt Fellow in Darmstadt, Germany, 1974.

Palestine (region)
Palestine ( el, Παλαιστίνη, ; la, Palaestina; ar, فلسطين, , , ; he, פלשתינה, ) is a geographic region in Western Asia. It is usually considered to include Israel and the State of Palestine (i.e. West Bank and Gaza Strip), though some definitions also include part of northwestern Jordan. The first written records to attest the name of the region were those of the Twentieth dynasty of Egypt, which used the term "Peleset" in reference to the neighboring people or land. In the 8th century, Assyrian inscriptions refer to the region of "Palashtu" or "Pilistu". In the Hellenistic period, these names were carried over into Greek, appearing in the Histories of Herodotus in the more recognizable form of "Palaistine". The Roman Empire initially used other terms for the region, such as Judaea, but renamed the region Syria Palaestina after the Bar Kokhba revolt. During the Byzantine period, the region was split into the provinces of Palaestina Prima, Palaestin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mach Reflection
Mach reflection is a supersonic fluid dynamics effect, named for Ernst Mach, and is a shock wave reflection pattern involving three shocks. Introduction Mach reflection can exist in steady, pseudo-steady and unsteady flows. When a shock wave, which is moving with a constant velocity, propagates over a solid wedge, the flow generated by the shock impinges on the wedge thus generating a second reflected shock, which ensures that the velocity of the flow is parallel to the wedge surface. Viewed in the frame of the reflection point, this flow is locally steady, and the flow is referred to as pseudosteady. When the angle between the wedge and the primary shock is sufficiently large, a single reflected shock is not able to turn the flow to a direction parallel to the wall and a transition to Mach reflection occurs. In a steady flow situation, if a wedge is placed into a steady supersonic flow in such a way that its oblique attached shock impinges on a flat wall parallel to the free s ...

American Academy Of Arts And Sciences
The American Academy of Arts and Sciences (abbreviation: AAA&S) is one of the oldest learned societies in the United States. It was founded in 1780 during the American Revolution by John Adams, John Hancock, James Bowdoin, Andrew Oliver, and other Founding Fathers of the United States. It is headquartered in Cambridge, Massachusetts. Membership in the academy is achieved through a thorough petition, review, and election process. The academy's quarterly journal, ''Dædalus'', is published by MIT Press on behalf of the academy. The academy also conducts multidisciplinary public policy research. History The Academy was established by the Massachusetts legislature on May 4, 1780, charted in order "to cultivate every art and science which may tend to advance the interest, honor, dignity, and happiness of a free, independent, and virtuous people." The sixty-two incorporating fellows represented varying interests and high standing in the political, professional, and commercial secto ...

Royal Aeronautical Society
The Royal Aeronautical Society, also known as the RAeS, is a British multi-disciplinary professional institution dedicated to the global aerospace community. Founded in 1866, it is the oldest aeronautical society in the world. Members, Fellows, and Companions of the society can use the post-nominal letters MRAeS, FRAeS, or CRAeS, respectively. Function The objectives of The Royal Aeronautical Society include: to support and maintain high professional standards in aerospace disciplines; to provide a unique source of specialist information and a local forum for the exchange of ideas; and to exert influence in the interests of aerospace in the public and industrial arenas, including universities. The Royal Aeronautical Society is a worldwide society with an international network of 67 branches. Many practitioners of aerospace disciplines use the Society's designatory post-nominals such aFRAeS CRAeS, MRAeS, AMRAeS, and ARAeS (incorporating the former graduate grade, GradRAeS). ...

American Institute Of Aeronautics And Astronautics
The American Institute of Aeronautics and Astronautics (AIAA) is a professional society for the field of aerospace engineering. The AIAA is the U.S. representative on the International Astronautical Federation and the International Council of the Aeronautical Sciences. In 2015, it had more than 30,000 members among aerospace professionals worldwide (a majority are American and/or live in the United States). History The AIAA was founded in 1963 from the merger of two earlier societies: the American Rocket Society (ARS), founded in 1930 as the American Interplanetary Society (AIS), and the Institute of the Aerospace Sciences (IAS), founded in 1932 as the Institute of the Aeronautical Sciences. Paul Johnston was the first executive director of the organization. Jim Harford took his seat after 18 months. The newly-formed structure gathered 47 technical committees and one broad technical publication, the ''AIAA Journal''. The ''AIAA Student Journal'' was also launched in 1963. T ...

He was responsible for many key advances in aerodynamics, notably on supersonic and hypersonic airflow characterization. He is regarded as an outstanding aerodynamic theoretician of the 20th century. Early life Theodore von Kármán was born into a Jewish family in Budapest, Austria-Hungary, as Kármán Tódor, the son of Helen (Kohn, hu, Kohn Ilka) and Mór Kármán. One of his ancestors was Rabbi Judah Loew ben Bezalel. He studied engineering at the city's Royal Joseph Technical University, known today as Budapest University of Technology and Economics. After graduating in 1902 he moved to the German Empire and joined Ludwig Prandtl at the University of Göttingen, where he received his doctorate in 1908. He taug ...
