Volta Conference
The Volta Conference was the name given to each of the international conferences held in Italy by the Royal Academy of Science in Rome, and funded by the Alessandro Volta Foundation. In the interwar period, they covered a number of topics in science and humanities, alternating between the two. The first conference, held at Lake Como in 1927, led to the public introduction of the uncertainty principle by Niels Bohr and Werner Heisenberg. The second conference did not take place until 1932; its topic was "Europe", and it was notable for the participation of a number of mainly fascist theorizers, along with non-fascists such as the British historian Christopher Dawson. In 1933 the third conference was on the subject of immunology, and "The Dramatic Theater" in 1934. During this period, the influence of Italian aeronautics was gaining momentum, led by General Gaetano Arturo Crocco, an aeronautical engineer who had become interested in ramjet engines in 1931, and influenced the select ...

Academic Conference
An academic conference or scientific conference (also congress, symposium, workshop, or meeting) is an event for researchers (not necessarily academics) to present and discuss their scholarly work. Together with academic or scientific journals and Preprint archives such as arXiv, conferences provide an important channel for exchange of information between researchers. Further benefits of participating in academic conferences include learning effects in terms of presentation skills and “academic habitus”, receiving feedback from peers for one’s own research, the possibility to engage in informal communication with peers about work opportunities and collaborations, and getting an overview of current research in one or more disciplines. Overview Conferences usually encompass various presentations. They tend to be short and concise, with a time span of about 10 to 30 minutes; presentations are usually followed by a . The work may be bundled in written form as academic pape ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christopher Dawson
Christopher Henry Dawson (12 October 188925 May 1970) was a British independent scholar, who wrote many books on cultural history and Christendom. Dawson has been called "the greatest English-speaking Catholic historian of the twentieth century". The 1988–1989 academic year at the College of Europe was named in Dawson's honour. Life Dawson was the only son of Lt. Colonel H.P. Dawson and Mary Louisa, eldest daughter of Archdeacon Bevan, Hay Castle. He was brought up at Hartlington Hall, Yorkshire. Dawson was educated at Winchester College and Trinity College, Oxford, where he obtained 2nd class honours in Modern History in 1911. After his degree he studied economics. He also read the work of the German theologian Ernst Troeltsch. Dawson's background was Anglo-Catholic, but he converted to Roman Catholicism in 1909. In 1916, Dawson married Valery Mills, daughter of the architect Walter Edward Mills. They had two daughters and one son. Writing Dawson began publishing ar ...

Adolf Busemann
Adolf Busemann (20 April 1901 – 3 November 1986) was a German aerospace engineer and influential Nazi-era pioneer in aerodynamics, specialising in supersonic airflows. He introduced the concept of swept wings and, after emigrating in 1947 to the United States under Operation Paperclip, invented the shockwave-free supersonic Busemann biplane. Education and early life Born in Lübeck, Germany, Busemann attended the Technical University of Braunschweig, receiving his Ph.D. in engineering in 1924. Career and research The next year he was given the position of aeronautical research scientist at the Max-Planck Institute where he joined the famed team led by Ludwig Prandtl, including Theodore von Kármán, Max Munk and Jakob Ackeret. In 1930 he was promoted to professor at University of Göttingen. He held various positions within the German scientific community during this period, and during the war he was the director of the Braunschweig Laboratory, a famous research establishment ...

Swept Wing
A swept wing is a wing that angles either backward or occasionally forward from its root rather than in a straight sideways direction. Swept wings have been flown since the pioneer days of aviation. Wing sweep at high speeds was first investigated in Germany as early as 1935 by Albert Betz and Adolph Busemann, finding application just before the end of the Second World War. It has the effect of delaying the shock waves and accompanying aerodynamic drag rise caused by fluid compressibility near the speed of sound, improving performance. Swept wings are therefore almost always used on jet aircraft designed to fly at these speeds. The term "swept wing" is normally used to mean "swept back", but variants include forward sweep, variable sweep wings and oblique wings in which one side sweeps forward and the other back. The delta wing is also aerodynamically a form of swept wing. Reasons for sweep There are three main reasons for sweeping a wing: 1. to arrange the center of gravity ...

Compressibility
In thermodynamics and fluid mechanics, the compressibility (also known as the coefficient of compressibility or, if the temperature is held constant, the isothermal compressibility) is a measure of the instantaneous relative volume change of a fluid or solid as a response to a pressure (or mean stress) change. In its simple form, the compressibility \kappa (denoted in some fields) may be expressed as :\beta =-\frac\frac, where is volume and is pressure. The choice to define compressibility as the negative of the fraction makes compressibility positive in the (usual) case that an increase in pressure induces a reduction in volume. The reciprocal of compressibility at fixed temperature is called the isothermal bulk modulus. Definition The specification above is incomplete, because for any object or system the magnitude of the compressibility depends strongly on whether the process is isentropic or isothermal. Accordingly, isothermal compressibility is defined: :\beta_T=-\frac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ramjet
A ramjet, or athodyd (aero thermodynamic duct), is a form of airbreathing jet engine that uses the forward motion of the engine to produce thrust. Since it produces no thrust when stationary (no ram air) ramjet-powered vehicles require an assisted take-off like a rocket assist to accelerate it to a speed where it begins to produce thrust. Ramjets work most efficiently at supersonic speeds around and can operate up to speeds of . Ramjets can be particularly useful in applications requiring a small and simple mechanism for high-speed use, such as missiles. The US, Canada, and UK had widespread ramjet powered missile defenses during the 1960s onward, such as the CIM-10 Bomarc and Bloodhound. Weapon designers are looking to use ramjet technology in artillery shells to give added range; a 120 mm mortar shell, if assisted by a ramjet, is thought to be able to attain a range of . They have also been used successfully, though not efficiently, as tip jets on the ends of helicopt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeronautical Engineer
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering. "Aeronautical engineering" was the original term for the field. As flight technology advanced to include vehicles operating in outer space, the broader term "aerospace engineering" has come into use. Aerospace engineering, particularly the astronautics branch, is often colloquially referred to as "rocket science". Overview Flight vehicles are subjected to demanding conditions such as those caused by changes in atmospheric pressure and temperature, with structural loads applied upon vehicle components. Consequently, they are usually the products of various technological and engineering disciplines including aerodynamics, Air propulsion, avionics, materials science, stru ...

Gaetano Arturo Crocco
Gaetano Arturo Crocco (26 October 1877 – 19 January 1968) was an Italian scientist and aeronautics pioneer, the founder of the Italian Rocket Society, and went on to become Italy's leading space scientist. He was born in Naples. In 1927, Crocco begun working with solid-propellant rockets and, in 1929, designed and built the first liquid-propellant rocket motors in Italy. He began work with monopropellants (fuel and oxidizer combined in one chemical liquid) in 1932, making him one of the first researchers in this field. As head of the School of Aeronautics of the University of Rome, he performed research on flight mechanics, structural design, and high-altitude flight in addition to his work in rocket propulsion. Because of his early efforts in aeronautics, Italian satellites were launched starting in the 1960s. The San Marco programme was a cooperative effort of NASA and the Italian Space Commission, with NASA providing launch vehicles, use of its facilities, and training o ...

Immunology
Immunology is a branch of medicineImmunology for Medical Students, Roderick Nairn, Matthew Helbert, Mosby, 2007 and biology that covers the medical study of immune systems in humans, animals, plants and sapient species. In such we can see there is a difference of human immunology and comparative immunology in veterinary medicine and animal biosciences. Immunology measures, uses charts and differentiate in context in medicine the studies of immunity on cell and molecular level, and the immune system as part of the physiological level as its functioning is of major importance. In the different states of both health, occurring symptoms and diseases; the functioning of the immune system and immunological responses such as autoimmune diseases, allergic hypersensitivities, or in some cases malfunctioning of immune system as for example in immunological disorders or in immune deficiency, and the specific transplant rejection) Immunology has applications in numerous disciplines of ...

Fascism
Fascism is a far-right, authoritarian, ultra-nationalist political ideology and movement,: "extreme militaristic nationalism, contempt for electoral democracy and political and cultural liberalism, a belief in natural social hierarchy and the rule of elites, and the desire to create a (German: “people’s community”), in which individual interests would be subordinated to the good of the nation" characterized by a dictatorial leader, centralized autocracy, militarism, forcible suppression of opposition, belief in a natural social hierarchy, subordination of individual interests for the perceived good of the nation and race, and strong regimentation of society and the economy. Fascism rose to prominence in early 20th-century Europe. The first fascist movements emerged in Italy during World War I, before spreading to other European countries, most notably Germany. Fascism also had adherents outside of Europe. Opposed to anarchism, democracy, pluralism, liberalism ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Werner Heisenberg
Werner Karl Heisenberg () (5 December 1901 – 1 February 1976) was a German theoretical physicist and one of the main pioneers of the theory of quantum mechanics. He published his work in 1925 in a breakthrough paper. In the subsequent series of papers with Max Born and Pascual Jordan, during the same year, his matrix formulation of quantum mechanics was substantially elaborated. He is known for the uncertainty principle, which he published in 1927. Heisenberg was awarded the 1932 Nobel Prize in Physics "for the creation of quantum mechanics". Heisenberg also made contributions to the theories of the hydrodynamics of turbulent flows, the atomic nucleus, ferromagnetism, cosmic rays, and subatomic particles. He was a principal scientist in the German nuclear weapons program during World War II. He was also instrumental in planning the first West German nuclear reactor at Karlsruhe, together with a research reactor in Munich, in 1957. Following World War II, he was appointed ...
