Oleg Lavrentiev
Oleg Alexandrovich Lavrentiev (russian: Оле́г Алекса́ндрович Лавре́нтьев; Pskov, Russia – in Kharkiv in Ukraine) was a Ukrainian physicist in the former Soviet atomic bomb project, Soviet program of nuclear weapons whose research contributions were fundamental to understanding of thermonuclear fusion. Biography Lavrentiev was born in Pskov, into a family descended from peasants. His father, Alexander, completed 2 years at a parochial school, worked as a clerk at a Pskov factory, his mother, Alexandra, completed 4 years, and worked as a nurse. During the war, at age 18 he volunteered for the front. He participated in the Baltic Offensive, battles for the Baltic States (1944–1945), transferred to the Far Eastern Military District, Sakhalin Military District, and continued military service in Poronaisk. He was a self-taught physicist who once allowed to attend the Moscow State University but did not secure graduation from there. Eventually, the Kh ...

Pskov
Pskov ( rus, Псков, a=pskov-ru.ogg, p=pskof; see also names in other languages) is a city in northwestern Russia and the administrative center of Pskov Oblast, located about east of the Estonian border, on the Velikaya River. Population: Pskov is one of the oldest cities in Russia. It served as the capital of the Pskov Republic and was a trading post of the Hanseatic League before it came under the control of the Grand Duchy of Moscow. History Early history Pskov is one of the oldest cities in Russia. The name of the city, originally Pleskov (historic Russian spelling , ''Plěskov''), may be loosely translated as "he townof purling waters". It was historically known in English as Plescow. Its earliest mention comes in 903, which records that Igor of Kiev married a local lady, Olga (later Saint Olga of Kiev). Pskovians sometimes take this year as the city's foundation date, and in 2003 a great jubilee took place to celebrate Pskov's 1,100th anniversary. The f ...

USSR
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev ( Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Gove ...

Kharkiv Theoretical Physics School
The Kharkiv Theoretical Physics School was founded by Lev Landau in Kharkov, Soviet Union (now Kharkiv, Ukraine). It is sometimes referred to as the Landau school — more precisely, one might say that Landau's group at Kharkiv was the beginning of the Landau school that, after Landau moved to the Kapitza’ Institute for Physical Problems in Moscow, included new generations of theoretical physicists from the countries of the former Soviet Union. Lev Landau was the head of the Kharkhiv Theoretical Physics School from 1932 to 1937, when he left for Moscow. His students at Kharkiv included Alexander Akhiezer, Evgeny Lifshitz, Ilya Lifshitz, and Isaak Pomeranchuk. Upon the recommendation of Edward Teller, László Tisza joined, in January 1935, Landau's group at Kharkiv and then returned to Budapest in 1937 after Landau's departure to Moscow. Landau developed a comprehensive exam called the "Theoretical Minimum" which students were expected to pass before admission to the school. The ...

Igor Tamm
Igor Yevgenyevich Tamm ( rus, И́горь Евге́ньевич Тамм , p=ˈiɡərʲ jɪvˈɡʲenʲjɪvitɕ ˈtam , a=Ru-Igor Yevgenyevich Tamm.ogg; 8 July 1895 – 12 April 1971) was a Soviet physicist who received the 1958 Nobel Prize in Physics, jointly with Pavel Alekseyevich Cherenkov and Ilya Mikhailovich Frank, for their 1934 discovery and demonstration of Cherenkov radiation. He also predicted the Quasi-particle Phonon, and in 1951, together with Andrei Sakharov were the proposers of the Tokamak system. Biography According to Russian sources, Tamm had German noble descent on his father's side through his grandfather Theodor Tamm, who emigrated from Thuringia. Although his surname "Tamm" is rather common in Estonia, other sources state he was Jewish or had Jewish ancestry. He studied at a gymnasium in Elisavetgrad (now Kropyvnytskyi, Ukraine). In 1913–1914 he studied at the University of Edinburgh together with his school-friend Boris Hessen. At the outbreak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Andrei Sakharov
Andrei Dmitrievich Sakharov ( rus, Андрей Дмитриевич Сахаров, p=ɐnˈdrʲej ˈdmʲitrʲɪjevʲɪtɕ ˈsaxərəf; 21 May 192114 December 1989) was a Soviet nuclear physicist, dissident, nobel laureate and activist for nuclear disarmament, peace, and human rights. He became renowned as the designer of the Soviet Union's RDS-37, a codename for Soviet development of thermonuclear weapons. Sakharov later became an advocate of civil liberties and civil reforms in the Soviet Union, for which he faced state persecution; these efforts earned him the Nobel Peace Prize in 1975. The Sakharov Prize, which is awarded annually by the European Parliament for people and organizations dedicated to human rights and freedoms, is named in his honor. Biography Early life Sakharov was born in Moscow on May 21, 1921. His father was Dmitri Ivanovich Sakharov, a physics professor and an amateur pianist. His father taught at the Second Moscow State University. Andrei's gran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fusion Power
Fusion power is a proposed form of power generation that would generate electricity by using heat from nuclear fusion, nuclear fusion reactions. In a fusion process, two lighter atomic nucleus, atomic nuclei combine to form a heavier nucleus, while releasing energy. Devices designed to harness this energy are known as fusion reactors. Research into fusion reactors began in the 1940s, but as of 2022, only one design, an Inertial confinement fusion, inertial confinement laser-driven fusion machine at the US National Ignition Facility, has conclusively produced a positive fusion energy gain factor, i.e. more power output than input. Fusion processes require fuel and a confined environment with sufficient temperature, pressure, and confinement time to create a plasma (physics), plasma in which fusion can occur. The combination of these figures that results in a power-producing system is known as the Lawson criterion. In stars, the most common fuel is hydrogen, and gravity provides ext ...

Lithium Deuteride
Lithium hydride is an inorganic compound with the formula Li H. This alkali metal hydride is a colorless solid, although commercial samples are grey. Characteristic of a salt-like (ionic) hydride, it has a high melting point, and it is not soluble but reactive with all protic organic solvents. It is soluble and nonreactive with certain molten salts such as lithium fluoride, lithium borohydride, and sodium hydride. With a molar mass of 7.95 g/mol, it is the lightest ionic compound. Physical properties LiH is a diamagnetic and an ionic conductor with a conductivity gradually increasing from at 443 °C to 0.18 Ω−1cm−1 at 754 °C; there is no discontinuity in this increase through the melting point. The dielectric constant of LiH decreases from 13.0 (static, low frequencies) to 3.6 (visible-light frequencies). LiH is a soft material with a Mohs hardness of 3.5. Its compressive creep (per 100 hours) rapidly increases from 100% at 475 °C, meaning that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
