Military Radio Station Of Pierre-sur-Haute
The Pierre-sur-Haute military radio station is a site used for French military communications. It has been used in the service of France since 1913. It is in the Sauvain and Job communes, with the boundary between the Rhône-Alpes and Auvergne regions passing through the site. There are three towers at the site. The tallest one is a 55-metre-high civilian telecommunication tower owned by . In April 2013, the French interior intelligence agency DCRI pressured the president of Wikimedia France into deleting the French-language Wikipedia article about the station. It was promptly restored by another Wikipedia contributor living in Switzerland. As a result of the controversy, the article temporarily became the most read page on the French Wikipedia, which was noted as an example of the Streisand effect. History In 1913, a semaphore telegraph station (french: télégraphe Chappe) was built where the military radio station is now. At the time, it was a small stone building, wi ...

Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Weapons
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions ( thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been deplo ...

Henrichemont
Henrichemont (), formerly known as Boisbelle, is a commune in the Cher department in the Centre-Val de Loire region of France. The village was created and named in honour of Henri IV in 1609 by Maximilien de Béthune, Duke of Sully to be the capital of the principality of Boisbelle and possibly a refuge for the protestants of the region. The principality approximated to the territories of the former canton of Henrichemont. The hamlet of La Borne is home to a restored tradition of stoneware pottery, attracting world-renowned artists and writers to stay there. The village is one of the most popular small tourist attractions in France. History Beginnings From ancient times, Boisbelle had been a sovereign allod. Under Roman law, an allod is a freehold with none of the constraints of feudal tenure. Being sovereign meant that the owner had the rights of a ruler and governed the territory in complete independence: he or she could make laws, administer justice and mint money. The in ...

The French Air and Space Force (AAE) (french: Armée de l'air et de l'espace, ) is the air and space force of the French Armed Forces. It was the first military aviation force in history, formed in 1909 as the , a service arm of the French Army; it became an independent military branch in 1934 as the French Air Force.

Arctic Polar Circle
The Arctic Circle is one of the two polar circles, and the most northerly of the five major circles of latitude as shown on maps of Earth. Its southern equivalent is the Antarctic Circle. The Arctic Circle marks the southernmost latitude at which, on the December solstice, the shortest day of the year in the northern hemisphere, the sun will not rise all day, and on the June solstice, the longest day of the year in the northern hemisphere, the sun will not set. These phenomena are referred to as polar night and midnight sun respectively, and the further north one progresses, the more pronounced these effects become. For example, in the Russian port city of Murmansk, three degrees above the Arctic Circle, the sun does not rise for 40 successive days in midwinter. The position of the Arctic Circle is not fixed and currently runs north of the Equator. Its latitude depends on the Earth's axial tilt, which fluctuates within a margin of more than 2° over a 41,000-year period, ...

Tropospheric Scatter
Tropospheric scatter, also known as troposcatter, is a method of communicating with microwave radio signals over considerable distances – often up to and further depending on frequency of operation, equipment type, terrain, and climate factors. This method of propagation uses the tropospheric scatter phenomenon, where radio waves at UHF and SHF frequencies are randomly scattered as they pass through the upper layers of the troposphere. Radio signals are transmitted in a narrow beam aimed just above the horizon in the direction of the receiver station. As the signals pass through the troposphere, some of the energy is scattered back toward the Earth, allowing the receiver station to pick up the signal. Normally, signals in the microwave frequency range travel in straight lines, and so are limited to '' line-of-sight'' applications, in which the receiver can be 'seen' by the transmitter. Communication distances are limited by the visual horizon to around . Troposcatter allow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
