Alexei Vasilievich Shubnikov
Alexei Vasilievich Shubnikov (russian: Алексей Васильевич Шубников; 29March 1887 – 27April 1970) was a Soviet crystallographer and mathematician. Shubnikov was the founding director of the Institute of Crystallography (named after him following his death) of the Academy of Sciences of the Soviet Union in Moscow. Shubnikov pioneered Russian crystallography and its application. Life Career In 1912 Shubnikov graduated from the Department of Natural Sciences of the Faculty of Physics and Mathematics of Moscow University. From 1920 to 1925 he was a professor at the Ural Mining Institute, Yekaterinburg. In 1925, at the invitation of the well-known mineralogist and geologist Alexander Fersman, he went to Leningrad, where he founded a laboratory of crystallography and laid the foundations of the Soviet school of theoretical and applied crystallography and related fields. From 1927 to 1929 he visited research institutions in Norway and Germany and worked te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Heinrich Heesch
Heinrich Heesch (June 25, 1906 – July 26, 1995) was a German mathematician. He was born in Kiel and died in Hanover. In Göttingen he worked on Group theory. In 1933 Heesch witnessed the National Socialist purges of university staff. Not willing to become a member of the National Socialist organization of university teachers as required, he resigned from his university position in 1935 and worked privately at his parents' home in Kiel until 1948. During this time he did research on tilings. In 1955 Heesch began teaching at Leibniz University Hannover and worked on graph theory. In this period Heesch did pioneering work in developing methods for a computer-aided proof of the then unproved four color theorem. In particular, he was the first to investigate the notion of "discharging", which turned out to be a fundamental ingredient of the eventual computer-aided proof by Kenneth Appel and Wolfgang Haken. Between 1967 and 1971, Heesch made several visits to the United States ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1970 Deaths
Year 197 ( CXCVII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 '' Ab urbe condita''). The denomination 197 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Hero Of Socialist Labour
The Hero of Socialist Labour (russian: links=no, Герой Социалистического Труда, Geroy Sotsialisticheskogo Truda) was an honorific title in the Soviet Union and other Warsaw Pact countries from 1938 to 1991. It represented the highest degree of distinction in the USSR and was awarded for exceptional achievements in Soviet industry and culture. It provided a similar status to the title of Hero of the Soviet Union, which was awarded for heroic deeds, but differed in that it was not awarded to foreign citizens. History The Title "Hero of Socialist Labour" was introduced by decree of the Presidium of the Supreme Soviet of the Soviet Union on December 27, 1938. Originally, Heroes of Socialist Labour were awarded the highest decoration of the Soviet Union, the Order of Lenin, and a diploma from the Presidium of the Supreme Soviet of the Soviet Union. In order to distinguish the Heroes of Socialist Labour from other Order of Lenin recipients, the " Hamme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Order Of Lenin
The Order of Lenin (russian: Орден Ленина, Orden Lenina, ), named after the leader of the Russian October Revolution, was established by the Central Executive Committee on April 6, 1930. The order was the highest civilian decoration bestowed by the Soviet Union. The order was awarded to: * Civilians for outstanding services rendered to the State * Members of the armed forces for exemplary service * Those who promoted friendship and cooperation between people and in strengthening peace * Those with meritorious services to the Soviet state and society From 1944 to 1957, before the institution of a specific length of service medals, the Order of Lenin was also used to reward 25 years of conspicuous military service. Those who were awarded the titles "Hero of the Soviet Union" and " Hero of Socialist Labour" were also given the order as part of the award. It was also bestowed on cities, companies, factories, regions, military units, and ships. Various educational instituti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Order Of The Red Banner Of Labour
The Order of the Red Banner of Labour (russian: Орден Трудового Красного Знамени, translit=Orden Trudovogo Krasnogo Znameni) was an order of the Soviet Union established to honour great deeds and services to the Soviet state and society in the fields of production, science, culture, literature, the arts, education, health, social and other spheres of labour activities. It is the labour counterpart of the military Order of the Red Banner. A few institutions and factories, being the pride of Soviet Union, also received the order. The Order of the Red Banner of Labour was the third-highest civil award in the Soviet Union, after the Order of Lenin and the Order of the October Revolution. The Order of the Red Banner of Labour began solely as an award of the Russian SFSR on December 28, 1920. The all-Union equivalent was established by Decree of the Presidium of the Supreme Soviet on September 7, 1928, and approved by another decree on September 15, 1 ...

Point Group
In geometry, a point group is a mathematical group of symmetry operations (isometries in a Euclidean space) that have a fixed point in common. The coordinate origin of the Euclidean space is conventionally taken to be a fixed point, and every point group in dimension ''d'' is then a subgroup of the orthogonal group O(''d''). Point groups are used to describe the symmetries of geometric figures and physical objects such as molecules. Each point group can be represented as sets of orthogonal matrices ''M'' that transform point ''x'' into point ''y'' according to Each element of a point group is either a rotation (determinant of ''M'' = 1), or it is a reflection or improper rotation (determinant of ''M'' = −1). The geometric symmetries of crystals are described by space groups, which allow translations and contain point groups as subgroups. Discrete point groups in more than one dimension come in infinite families, but from the crystallographic restriction theorem and ...
