Kourovka, Sverdlovsk Oblast
Kourovka (russian: Коу́ровка) is a types of inhabited localities in Russia, settlement in Pervouralsk Subdivisions of Russia#Municipal divisions, Urban okrug in Sverdlovsk Oblast, Russia. Population: Kourovka was founded in 1908 or 1909 as a railroad town near a station of the Trans-Siberian railway. It bears its name from the ''Kourov log'' ravine, named after Kour, peasant of the nearby who lived in late 17th century. In its turn, Kourovka is the namesake of a :ru:Коуровская улица, street in Yekaterinburg, a minor planet 4964 Kourovka and Kourovka Notebook, a set of open problems in group theory. An Art Nouveau station building is the oldest building in Kourovka. Kourovka Astronomical Observatory is located near the settlement. In 1965 the first All-USSR Symposium on Group Theory has been hosted in Kourovka. References Notes __NOTOC__ {{Authority control Urban-type settlements in Sverdlovsk Oblast ...

Sverdlovsk Oblast
Sverdlovsk Oblast ( rus, Свердловская область, Sverdlovskaya oblast) is a federal subject (an oblast) of Russia located in the Ural Federal District. Its administrative center is the city of Yekaterinburg, formerly known as Sverdlovsk. Its population is 4,297,747 (according to the 2010 Census). Geography Most of the oblast is spread over the eastern slopes of the Middle and North Urals and the Western Siberian Plain. Only in the southwest does the oblast stretch onto the western slopes of the Ural Mountains. The highest mountains all rise in the North Urals, Konzhakovsky Kamen at and Denezhkin Kamen at . The Middle Urals is mostly hilly country with no discernible peaks; the mean elevation is closer to above sea level. Principal rivers include the Tavda, the Tura, the Chusovaya, and the Ufa, the latter two being tributaries of the Kama. Sverdlovsk Oblast borders with, clockwise from the west, Perm Krai, the Komi Republic, Khanty–Mansi Auton ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trans-Siberian Railway
The Trans-Siberian Railway (TSR; , , ) connects European Russia to the Russian Far East. Spanning a length of over , it is the longest railway line in the world. It runs from the city of Moscow in the west to the city of Vladivostok in the east. During the period of the Russian Empire, government ministers—personally appointed by Alexander III and his son Nicholas II—supervised the building of the railway network between 1891 and 1916. Even before its completion, the line attracted travelers who documented their experiences. Since 1916, the Trans-Siberian Railway has directly connected Moscow with Vladivostok. , expansion projects remain underway, with connections being built to Russia's neighbors (namely Mongolia, China, and North Korea). Additionally, there have been proposals and talks to expand the network to Tokyo, Japan, with new bridges that would connect the mainland railway through the Russian island of Sakhalin and the Japanese island of Hokkaido.

Group Theory
In abstract algebra, group theory studies the algebraic structures known as group (mathematics), groups. The concept of a group is central to abstract algebra: other well-known algebraic structures, such as ring (mathematics), rings, field (mathematics), fields, and vector spaces, can all be seen as groups endowed with additional operation (mathematics), operations and axioms. Groups recur throughout mathematics, and the methods of group theory have influenced many parts of algebra. Linear algebraic groups and Lie groups are two branches of group theory that have experienced advances and have become subject areas in their own right. Various physical systems, such as crystals and the hydrogen atom, and Standard Model, three of the four known fundamental forces in the universe, may be modelled by symmetry groups. Thus group theory and the closely related representation theory have many important applications in physics, chemistry, and materials science. Group theory is also ce ...
