Aquitaine
Aquitaine ( , , ; oc, Aquitània ; eu, Akitania; Poitevin-Saintongeais: ''Aguiéne''), archaic Guyenne or Guienne ( oc, Guiana), is a historical region of southwestern France and a former administrative region of the country. Since 1 January 2016 it has been part of the region of Nouvelle-Aquitaine. It is situated in the southwest corner of Metropolitan France, along the Atlantic Ocean and the Pyrenees mountain range on the border with Spain, and for most of its written history Bordeaux has been a vital port and administrative center. It is composed of the five departments of Dordogne, Lot-et-Garonne, Pyrénées-Atlantiques, Landes and Gironde. Gallia Aquitania was established by the Romans in ancient times and in the Middle Ages, Aquitaine was a kingdom and a duchy, whose boundaries fluctuated considerably.

Nuclear Weapon
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 d ...

Commune (France)
The () is a level of administrative division in the French Republic. French are analogous to civil townships and incorporated municipalities in the United States and Canada, ' in Germany, ' in Italy, or ' in Spain. The United Kingdom's equivalent are civil parishes, although some areas, particularly urban areas, are unparished. are based on historical geographic communities or villages and are vested with significant powers to manage the populations and land of the geographic area covered. The are the fourth-level administrative divisions of France. vary widely in size and area, from large sprawling cities with millions of inhabitants like Paris, to small hamlets with only a handful of inhabitants. typically are based on pre-existing villages and facilitate local governance. All have names, but not all named geographic areas or groups of people residing together are ( or ), the difference residing in the lack of administrative powers. Except for the municipal arrondi ...

Arcachon
Arcachon ( ; ) is a commune in the southwestern French department of Gironde. It is a popular seaside resort on the Atlantic coast southwest of Bordeaux, in the Landes forest. It has a sandy beach and a mild climate said to be favourable for invalids suffering from pulmonary complaints. Arcachon is twinned with five cities. History On 2 May 1857, Emperor Napoleon III signed an imperial decree declaring that Arcachon was now an autonomous municipality; coincidentally, the railway line extension from Bordeaux to Arcachon had been completed that same year. At that time, Arcachon was scarcely more than a forest of pine trees, oaks and strawberry trees (arbutus), with no road links and few real houses, with a population fewer than 400 people, mostly fishermen and peasants. In earlier years, when some hygienists began to recommend sea bathing, three sea establishments were laid out by investors to attract the Bordeaux bourgeoisie and other wealthy people. This was the beginning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megajoule Laser
The joule ( , ; symbol: J) is the unit of energy in the International System of Units (SI). It is equal to the amount of work done when a force of 1 newton displaces a mass through a distance of 1 metre in the direction of the force applied. It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (1818–1889). Definition In terms of SI base units and in terms of SI derived units with special names, the joule is defined as One joule can also be defined by any of the following: * The work required to move an electric charge of one coulomb through an electrical potential difference of one volt, or one coulomb-volt (C⋅V). This relationship can be used to define the volt. * The work required to produce one watt of power for one second, or one watt-second (W⋅s) (compare kilowatt-hour, which is 3.6 megajoules). This relationship can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Testing
Nuclear weapons tests are experiments carried out to determine nuclear weapons' effectiveness, yield, and explosive capability. Testing nuclear weapons offers practical information about how the weapons function, how detonations are affected by different conditions, and how personnel, structures, and equipment are affected when subjected to nuclear explosions. However, nuclear testing has often been used as an indicator of scientific and military strength. Many tests have been overtly political in their intention; most nuclear weapons states publicly declared their nuclear status through a nuclear test. The first nuclear device was detonated as a test by the United States at the Trinity site in New Mexico on July 16, 1945, with a yield approximately equivalent to 20 kilotons of TNT. The first thermonuclear weapon technology test of an engineered device, codenamed "Ivy Mike", was tested at the Enewetak Atoll in the Marshall Islands on November 1, 1952 (local date), also by the U ...

National Ignition Facility
The National Ignition Facility (NIF) is a laser-based inertial confinement fusion (ICF) research device, located at Lawrence Livermore National Laboratory in Livermore, California, United States. NIF's mission is to achieve fusion ignition with high energy gain. It achieved the first scientific breakeven controlled fusion experiment on December 5, 2022, with an energy gain factor of 1.5. It supports nuclear weapon maintenance and design by studying the behavior of matter under the conditions found within nuclear explosions. NIF is the largest and most powerful ICF device built to date. The basic ICF concept is to squeeze a small amount of fuel to reach pressure and temperature necessary for fusion. NIF hosts the world's most energetic laser. The laser heats the outer layer of a small sphere. The energy is so intense that it causes the sphere to implode, squeezing the fuel inside. The implosion reaches a peak speed of , raising the fuel density from about that of water to abo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Government Agencies Of France
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] |
