Military Physics Institute
Military Physics Institute ( sv, Militärfysiska institutet, MFI) was a Swedish research institution established in 1941 to 1945. It was amalgamated into the Swedish National Defence Research Institute in 1945. History The initiative for the establishment of the Military Physics Institute was taken in 1939 when the leaders of the country's physical institutions joined forces to make more effective use of the physical research results for military purposes. The Military Physics Institute was established in 1940 by the Swedish National Committee for Physics (''Svenska nationalkommitten för fysik'') and the year after state funding for the operation was applied. Research within the Military Physics Institute focused on the development of new weapons of defense. These include surveys of the military use of infrared radiation as well as the problems of shaped charge. An area in Södertörn near Grindsjön was donated by Olof Arrhenius, at which the institute built a test station for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swedish National Defence Research Institute
Swedish National Defence Research Institute ( sv, Försvarets forskningsanstalt, FOA) was a Swedish government agency in defense research existing from 1945 to 31 December 2000. It was amalgamated with the National Aeronautical Research Institute (FFA) into the Swedish Defence Research Agency (FOI) which was established on 1 January 2001. History The National Defence Research Institute (FOA) was established in 1945 (Instruction TS C:II No. 24), and took over operations at the Swedish Armed Forces Chemical Institute (''Försvarsväsendets kemiska anstalt'', FKA), the Military Physics Institute and the Telecommunications Technical Working Group of the Swedish Board of Inventions (''Statens uppfinnarnämnds teletekniska arbetsgrupp'', SUN), that is, essentially all technical and scientific research outside the industry. FOA was organized in three research departments, FOA 1 chemistry/medicine, FOA 2 general physics and FOA 3 telecommunications and an office. In 1959 FOA 4 (nuclear ...

Infrared
Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from around 1 millimeter (300 GHz) to the nominal red edge of the visible spectrum, around 700 nanometers (430 THz). Longer IR wavelengths (30 μm-100 μm) are sometimes included as part of the terahertz radiation range. Almost all black-body radiation from objects near room temperature is at infrared wavelengths. As a form of electromagnetic radiation, IR propagates energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. It was long known that fires emit invisible heat; in 1681 the pioneering experimenter Edme Mariotte showed that glass, though transparent to sunlight, obstructed radiant heat. In 1800 the astronomer Sir William Herschel discovered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shaped Charge
A shaped charge is an explosive charge shaped to form an explosively formed penetrator (EFP) to focus the effect of the explosive's energy. Different types of shaped charges are used for various purposes such as cutting and forming metal, initiating nuclear weapons, penetrating armor, or perforating wells in the oil and gas industry. A typical modern shaped charge, with a metal liner on the charge cavity, can penetrate armor steel to a depth of seven or more times the diameter of the charge (charge diameters, CD), though greater depths of 10 CD and above have been achieved. Contrary to a misconception (possibly resulting from the acronym for ''high-explosive anti-tank'', HEAT) the shaped charge EFP jet does not depend in any way on heating or melting for its effectiveness; that is, the EFP jet from a shaped charge does not melt its way through armor, as its effect is purely kinetic in nature – however the process does create significant heat and often has a significant ...

Södertörn
Södertörn is a roughly triangular peninsula and artificial island in eastern Södermanland, Sweden, which is bordered by: *Lake Mälaren and the inlet of Saltsjön (a part of the Baltic Sea) to the north, *The Baltic Sea (the Stockholm Archipelago) to the east and the south, *Himmerfjärden and Hallsfjärden (parts of the Baltic Sea) to the west as well as *The Södertälje Canal to the northwest. The Södertälje Canal is man-made, so the area isn't fully separated from the mainland by nature. The area is classified as an island by Statistics Sweden, making it the third largest island in Sweden. Since 2005, the whole of Södertörn has been included in List of metropolitan areas in Sweden#Metropolitan Stockholm, Metropolitan Stockholm. Before that, the southern parts of the island, which lie within Nynäshamn Municipality, and the western parts, which are in Södertälje Municipality, were – although in Stockholm County – not included in the metropolitan area.

Physics Institutes
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physics. (. ...

Military Research Of Sweden
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Research Institutes In Sweden
Research is "creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion on past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, economic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Government Agencies Established In 1941
A government is the system or group of people governing an organized community, generally a state. In the case of its broad associative definition, government normally consists of legislature, executive, and judiciary. Government is a means by which organizational policies are enforced, as well as a mechanism for determining policy. In many countries, the government has a kind of constitution, a statement of its governing principles and philosophy. While all types of organizations have governance, the term ''government'' is often used more specifically to refer to the approximately 200 independent national governments and subsidiary organizations. The major types of political systems in the modern era are democracies, monarchies, and authoritarian and totalitarian regimes. Historically prevalent forms of government include monarchy, aristocracy, timocracy, oligarchy, democracy, theocracy, and tyranny. These forms are not always mutually exclusive, and mixed governme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
