Artsimovich (crater)
Lev Andreyevich Artsimovich ( Russian: Лев Андреевич Арцимович, February 25, 1909 – March 1, 1973), also transliterated Arzimowitsch, was a Soviet physicist known for his contributions to the Tokamak— a device that produces controlled thermonuclear fusion power. Prior to conceiving the idea on nuclear fusion, Artsimovich participated in the former Soviet program of nuclear weapons, and was a recipient of many former Soviet honors and awards. Biography Artsimovich was born on 25 February 1909 in Moscow in the Russian Empire. His family had Polish nobility roots; nonetheless, he was described as Russian by his autobiographer in 1985. His grandfather, a professor, was exiled to Siberia after the Polish uprising against Tsarist Russia in 1863 and married a Russian woman, later settling in Smolensk. His father was educated at Lviv University; his mother was a pianist trained in Switzerland. In 1923, Soviet authorities moved the Artsimovich family (due t ...

Commemorative Stamp
A commemorative stamp is a postage stamp, often issued on a significant date such as an anniversary, to honor or commemorate a place, event, person, or object. The ''subject'' of the commemorative stamp is usually spelled out in print, unlike definitive stamps which normally depict the subject along with the denomination and country name only. Many postal services issue several commemorative stamps each year, sometimes holding first day of issue ceremonies at locations connected with the subjects. Commemorative stamps can be used alongside ordinary stamps. Unlike definitive stamps that are often reprinted and sold over a prolonged period of time for general usage, commemorative stamps are usually printed in limited quantities and sold for a much shorter period of time, usually, until supplies run out. First commemoratives There are several candidates for the title of the first commemorative. A 17-cent stamp issued in 1860 by New Brunswick, showing the Prince of Wales in antic ...

Anti-Stalinist Left
The anti-Stalinist left encompasses various kinds of Left-wing politics, left-wing political movements that oppose Joseph Stalin, Stalinism, neo-Stalinism and the History of the Soviet Union (1927–1953), system of governance that Stalin implemented as leader of the Soviet Union between 1924 and 1953. This term also refers to those that opposed Joseph Stalin and his leadership from within the Communist movement, such as Leon Trotsky and the party's Left Opposition.

In recent years, the term may also refer to left and centre-left wing opposition to dictatorships, cults of personality, totalitarianism and police states, all being features commonly attributed to Marxist-Leninist regimes that took inspiration from Stalinism such as the regimes of Kim Il Sung, Enver Hoxha and others, including in the former Eastern Bloc.

January Uprising
The January Uprising was an insurrection principally in Russia's Kingdom of Poland that was aimed at putting an end to Russian occupation of part of Poland and regaining independence. It began on 22 January 1863 and continued until the last insurgents were captured by the Russian forces in 1864. It was the longest-lasting insurgency in partitioned Poland. The conflict engaged all levels of society and arguably had profound repercussions on contemporary international relations and ultimately transformed Polish society. A confluence of factors rendered the uprising inevitable in early 1863. The Polish nobility and urban bourgeois circles longed for the semi-autonomous status they had enjoyed in Congress Poland before the previous insurgency, a generation earlier in 1830, and youth encouraged by the success of the Italian independence movement urgently desired the same outcome.

Russian People
Russians ( ) are an East Slavic ethnic group native to Eastern Europe. Their mother tongue is Russian, the most spoken Slavic language. The majority of Russians adhere to Orthodox Christianity, ever since the Middle Ages. By total numbers, they compose the largest Slavic and European nation. Genetic studies show that Russians are closely related to Poles, Belarusians, Ukrainians, as well as Estonians, Latvians, Lithuanians, and Finns. They were formed from East Slavic tribes, and their cultural ancestry is based in Kievan Rus'. The Russian word for the Russians is derived from the people of Rus' and the territory of Rus'. Russians share many historical and cultural traits with other European peoples, and especially with other East Slavic ethnic groups, specifically Belarusians and Ukrainians. The vast majority of Russians live in native Russia, but notable minorities are scattered throughout other post-Soviet states such as Belarus, Kazakhstan, Moldova, Ukraine, and ...

Soviet Nuclear Program
The Soviet atomic bomb project was authorized by Joseph Stalin in the Soviet Union to develop nuclear weapons during and after World War II. Russian physicist Georgy Flyorov suspected that the Allies of World War II, Allied powers were secretly developing a "Weapon of mass destruction, superweapon" since 1939. Flyorov urged Stalin to start a nuclear program in 1942. Early efforts mostly consisted of research at Kurchatov Institute, Laboratory No. 2 in Moscow, and intelligence gathering of Soviet-sympathizing atomic spies in the US Manhattan Project. Subsequent efforts involved plutonium production at Mayak in Chelyabinsk Oblast, Chelyabinsk and weapon research and assembly at KB-11 in Sarov. After Stalin learned of the atomic bombings of Hiroshima and Nagasaki, the nuclear program was accelerated through intelligence gathering about the Manhattan Project and German nuclear weapon project.

Nuclear Fusion
Nuclear fusion is a nuclear reaction, reaction in which two or more atomic nuclei combine to form a larger nuclei, nuclei/neutrons, neutron by-products. The difference in mass between the reactants and products is manifested as either the release or absorption (electromagnetic radiation), absorption of energy. This difference in mass arises as a result of the difference in nuclear binding energy between the atomic nuclei before and after the fusion reaction. Nuclear fusion is the process that powers all active stars, via many Stellar nucleosynthesis, reaction pathways. Fusion processes require an extremely large Lawson criterion, triple product of temperature, density, and confinement time. These conditions occur only in Stellar core, stellar cores, advanced Nuclear weapon design, nuclear weapons, and are approached in List of fusion experiments, fusion power experiments. A nuclear fusion process that produces atomic nuclei lighter than nickel-62 is generally exothermic, due t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
