Alexander Andreevich Samarskii
Alexander Andreevich Samarskii (Александр Андреевич Самарский, 19 February 1919, Amvrosiivka, metropolitan Donetsk, Yekaterinoslav Governorate – 11 February 2008, Moscow) was a Soviet and Russian mathematician and academician (USSR Academy of Sciences, Russian Academy of Sciences), specializing in mathematical physics, applied mathematics, numerical analysis, mathematical modeling, finite difference methods. Education and career Born in Amvrosiivka, Yekaterinoslav Governorate, Russian Empire (now, Donetsk Oblast, Ukraine). Samarskii studied from 1936 at Moscow State University, interrupted from 1941 to 1944 by voluntary military service in WW II — he was severely wounded in the Battle of Moscow. In 1948 he received his Russian candidate degree (Ph.D.). At the same time, he worked with Andrey Nikolayevich Tikhonov on mathematical modeling of nuclear weapon explosions and electromagnetic fields in waveguides. In the 1950s Samarskii worked on finite d ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Nuclear Physics
Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions, in addition to the study of other forms of nuclear matter. Nuclear physics should not be confused with atomic physics, which studies the atom as a whole, including its electrons. Discoveries in nuclear physics have led to applications in many fields. This includes nuclear power, nuclear weapons, nuclear medicine and magnetic resonance imaging, industrial and agricultural isotopes, ion implantation in materials engineering, and radiocarbon dating in geology and archaeology. Such applications are studied in the field of nuclear engineering. Particle physics evolved out of nuclear physics and the two fields are typically taught in close association. Nuclear astrophysics, the application of nuclear physics to astrophysics, is crucial in explaining the inner workings of stars and the origin of the chemical elements.

Stability Theory
In mathematics, stability theory addresses the stability of solutions of differential equations and of trajectories of dynamical systems under small perturbations of initial conditions. The heat equation, for example, is a stable partial differential equation because small perturbations of initial data lead to small variations in temperature at a later time as a result of the maximum principle. In partial differential equations one may measure the distances between functions using Lp norms or the sup norm, while in differential geometry one may measure the distance between spaces using the Gromov–Hausdorff distance. In dynamical systems, an orbit is called ''Lyapunov stable'' if the forward orbit of any point is in a small enough neighborhood or it stays in a small (but perhaps, larger) neighborhood. Various criteria have been developed to prove stability or instability of an orbit. Under favorable circumstances, the question may be reduced to a well-studied problem involvi ...

The National Academy Of Sciences Of Ukraine
The National Academy of Sciences of Ukraine (NASU; uk, Національна академія наук України, ''Natsional’na akademiya nauk Ukrayiny'', abbr: NAN Ukraine) is a self-governing state-funded organization in Ukraine that is the main center of development of science and technology by coordinating a system of research institutes in the country. It is the main research oriented organization along with the five other academies in Ukraine specialized in various scientific disciplines. NAS Ukraine consists of numerous departments, sections, research institutes, scientific centers and various other supporting scientific organizations. The Academy reports on the annual basis to the Cabinet of Ministers of Ukraine. The presidium of the academy is located at vulytsia Volodymyrska, 57, across the street from the Building of Pedagogical Museum, which was used to host the Central Council during the independence period of 1917-18. In 1919–1991 it was a repu ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

The National Academy Of Sciences Of Belarus
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a ...

Akademie Der Wissenschaften Der DDR
The German Academy of Sciences at Berlin, german: Deutsche Akademie der Wissenschaften zu Berlin (DAW), in 1972 renamed the Academy of Sciences of the GDR (''Akademie der Wissenschaften der DDR (AdW)''), was the most eminent research institution of East Germany (German Democratic Republic, GDR). The academy was established in 1946 in an attempt to continue the tradition of the Prussian Academy of Sciences and the Brandenburg Society of Sciences, founded in 1700 by Gottfried Wilhelm Leibniz. The academy was a learned society (scholarship society), in which awarded membership via election constituted scientific recognition. Unlike other academies of science, the DAW was also the host organization of a scientific community of non-academic research institutes. Upon German reunification, the Academy's learned society was dissociated from its research institutes and any other affiliates and eventually dissolved in 1992. Since 1993, activities of the AdW's members and college have been ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

International Congress Of Mathematicians
The International Congress of Mathematicians (ICM) is the largest conference for the topic of mathematics. It meets once every four years, hosted by the International Mathematical Union (IMU). The Fields Medals, the Nevanlinna Prize (to be renamed as the IMU Abacus Medal), the Carl Friedrich Gauss Prize, Gauss Prize, and the Chern Medal are awarded during the congress's opening ceremony. Each congress is memorialized by a printed set of Proceedings recording academic papers based on invited talks intended to be relevant to current topics of general interest. Being List of International Congresses of Mathematicians Plenary and Invited Speakers, invited to talk at the ICM has been called "the equivalent ... of an induction to a hall of fame".

USSR State Prize
The USSR State Prize (russian: links=no, Государственная премия СССР, Gosudarstvennaya premiya SSSR) was the Soviet Union's state honor. It was established on 9 September 1966. After the dissolution of the Soviet Union, the prize was followed up by the State Prize of the Russian Federation. The State Stalin Prize ( Государственная Сталинская премия, ''Gosudarstvennaya Stalinskaya premiya''), usually called the Stalin Prize, existed from 1941 to 1954, although some sources give a termination date of 1952. It essentially played the same role; therefore upon the establishment of the USSR State Prize, the diplomas and badges of the recipients of Stalin Prize were changed to that of USSR State Prize. In 1944 and 1945, the last two years of the Second World War, the award ceremonies for the Stalin Prize were not held. Instead, in 1946 the ceremony was held twice: in January for the works created in 1943–1944 and in June for the ...
