Tsiolkovsky Rocket Equation
Konstantin Eduardovich Tsiolkovsky (russian: Константи́н Эдуа́рдович Циолко́вский , , p=kənstɐnʲˈtʲin ɪdʊˈardəvʲɪtɕ tsɨɐlˈkofskʲɪj , a=Ru-Konstantin Tsiolkovsky.oga; – 19 September 1935) was a Russian and Soviet rocket scientist who pioneered astronautic theory. Along with the Frenchman Robert Esnault-Pelterie, the Germans Hermann Oberth and Fritz von Opel, and the American Robert H. Goddard, he is one of the founding fathers of modern rocketry and astronautics. His works later inspired leading Soviet rocket-engineers Sergei Korolev and Valentin Glushko, who contributed to the success of the Soviet space program. Tsiolkovsky spent most of his life in a log house on the outskirts of Kaluga, about southwest of Moscow. A recluse by nature, his unusual habits made him seem bizarre to his fellow townsfolk. Early life Tsiolkovsky was born in Izhevskoye (now in Spassky District, Ryazan Oblast), in the Russian Empire, to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soviet Space Program
The Soviet space program (russian: Космическая программа СССР, Kosmicheskaya programma SSSR) was the national space program of the former Union of Soviet Socialist Republics (USSR), active from 1955 until the dissolution of the Soviet Union in 1991. Soviet investigations in rocketry began with the formation of a research laboratory in 1921, but these efforts were hampered by the devastating war with Germany. Competing in the Space Race with the United States and later with the European Union and China, the Soviet program was notable in setting many records in space exploration, including the first intercontinental missile that launched the first satellite and sent the first animal into Earth orbit in 1957, and placed the first human in space in 1961. In addition, the Soviet program also saw the first woman in space in 1963 and a cosmonaut performing the first spacewalk in 1965. Other milestones included computerized robotic missions exploring t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russian Cosmism
Russian cosmism, also cosmism, is a philosophical and cultural movement that emerged in Russia at the turn of the 19th century, and again, at the beginning of the 20th century. At the beginning of the 20th century, there was a burst of scientific investigation into interplanetary travel, largely driven by fiction writers such as Jules Verne and H. G. Wells as well as philosophical movements like the Russian cosmism. Theory Cosmism entailed a broad theory of natural philosophy, combining elements of religion and ethics with a history and philosophy of the origin, evolution, and future existence of the cosmos and humankind. It combined elements from both Eastern and Western philosophic traditions as well as from the Russian Orthodox Church. Cosmism was one of the influences on Proletkult, and after the October Revolution, the term came to be applied to "...the poetry of such writers as Mikhail Gerasimov and Vladimir Kirillov...: emotional paeans to physical labor, machines, an ...

Rumyantsev Museum
The Rumyantsev Museum evolved from the personal library and historical collection of Count Nikolay Rumyantsev (1754–1826). Its origin was in St. Petersburg in the Rumyantsev house or mansion, building number 44 on the English Embankment overlooking river Neva. After Nikolay died in 1826, his brother Sergei converted the house into a museum. It was opened to the general public in 1831, initially for one day a week, and the remaining days were for study. Maintenance difficulties were among the reasons for the shift of Rumyantsev Museum to Moscow, despite it being affiliated to the Public Library in Saint Petersburg since 1845. In 1862, Nikolay's collection was combined with others, including paintings from the Hermitage Museum, and renamed the Moscow Public Museum and Rumyantsev Museum. By 1917 there would be four name changes and the collection grew to 1.5 million items. This increased to 2.7 million in the next three years following an expropriation and nationalisation campai ...

Some of the communities residing outside Tatarstan developed before the Russian Revolution of 1917, as Tatars were specialized in trading. During the 14th century, Sunni Islam was adopted by many of the Tatars. Tatars became subjects of Russia after the Siege of Kazan in 1552. Russians were using the Tatar ethnonym during the 18th and 19th centuries to denote all Turkic inhabitants of the Russian Empi ...

Russian Orthodoxy
Russian Orthodoxy (russian: Русское православие) is the body of several churches within the larger communion of Eastern Orthodox Christianity, whose liturgy is or was traditionally conducted in Church Slavonic language. Most Churches of the Russian Orthodox tradition are part of the Eastern Orthodox Church. Origin Historically, the term "Greek Orthodox" has been used to describe all Eastern Orthodox churches, since the term "Greek" can refer to the heritage of the Byzantine Empire. However, after the fall of Constantinople, the Greek influence decreased. Having lost its Christian '' basileus'' after the Turkish conquest, Constantinople, as a center of power, lost a significant part of its authority. On the other hand, the Moscow rulers soon began to consider themselves real ''Tsars'' (this title was already used by Ivan III), and therefore, according to them, the center of the Eastern Orthodox Church should be located in Moscow, and thus the bishop of Moscow ...
