Russian Stamps
A Russian Empire postman. This a survey of the postage stamps and postal history of the Russian Empire, the Soviet Union and the modern Russian Federation. Postal history Early history Records mention a system of messengers in the 10th century. Early letters were carried in the form of a roll, with a wax or lead seal; the earliest known of these seals dates from 1079, and mentions a governor Ratibor of Tmutarakan. The earliest surviving cover was sent in 1391 from La Tana (now Azov) to Venice. By the 16th century, the postal system included 1,600 locations, and mail took 3 days to travel from Moscow to Novgorod. In 1634, a peace treaty between Russia and Poland established a route to Warsaw, becoming Russia's first regular international service. Russian Empire Peter the Great enacted reforms making the postal system more uniform in its operations, and in 1714 the first general post offices opened in Saint Petersburg and Moscow. “Regular post-service” was establ ...

Crystallography
Crystallography is the experimental science of determining the arrangement of atoms in crystalline solids. Crystallography is a fundamental subject in the fields of materials science and solid-state physics (condensed matter physics). The word "crystallography" is derived from the Greek word κρύσταλλος (''krystallos'') "clear ice, rock-crystal", with its meaning extending to all solids with some degree of transparency, and γράφειν (''graphein'') "to write". In July 2012, the United Nations recognised the importance of the science of crystallography by proclaiming that 2014 would be the International Year of Crystallography. denote a direction vector (in real space). * Coordinates in ''angle brackets'' or ''chevrons'' such as <100> denote a ''family'' of directions which are related by symmetry operations.

Igor Kurchatov
Igor Vasil'evich Kurchatov (russian: Игорь Васильевич Курчатов; 12 January 1903 – 7 February 1960), was a Soviet physicist who played a central role in organizing and directing the former Soviet program of nuclear weapons. As many of his contemporaries in Russia, Kurchatov, initially educated as a naval architect, was an ''autodict'' in nuclear physics and was brought by Soviet establishment to accelerate the feasibility of the "super bomb". Aided by effective intelligence management by Soviet agencies on American Manhattan Project, Kurchatov oversaw the quick development and testing of the first Soviet nuclear weapon, which was roughly based on the first American device, at Semipalatinsk in Kazakhstan in 1949. Kurchatov, a recipient of many former Soviet honors, had a instrumental role in modern nuclear industry in Russia but his health decline rapidly that is mainly attributed to a 1949 radiation accident in Chelyabinsk-40 (a much more serious ...

Kirov Plant
The Kirov Plant, Kirov Factory or Leningrad Kirov Plant (LKZ) ( rus, Кировский завод, Kirovskiy zavod) is a major Russian mechanical engineering and agricultural machinery manufacturing plant in St. Petersburg, Russia. It was established in 1789, then moved to its present site in 1801 as a foundry for cannonballs. The Kirov Plant is sometimes confused with another Leningrad heavy weapons manufacturer, ''Factory No. 185 (S.M. Kirov)''. Recently the main production of the company is Kirovets heavy tractors. History In 1868 Nikolay Putilov (1820-1880) purchased the bankrupt plant; at the Putilov Works the Putilov Company (a joint-stock holding company from 1873) initially produced rolling stock for railways. The establishment boomed during the Russian industrialization of the 1890s, with the work-force quadrupling in a decade, reaching 12,400 in 1900. The factory traditionally produced goods for the Russian government, with railway products accounting for more than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auto Mechanic
An auto mechanic (automotive technician in most of North America, light vehicle technician in British English, and motor mechanic in Australian English) is a mechanic who services and repairs automobiles, sometimes specializing in one or more automobile brands or sometimes working with any brand. In fixing cars, their main role is to diagnose and repair the problem accurately and quickly. They often have to quote prices for their customers before commencing work or after partial disassembly for inspection. Their job may involve the repair of a specific part or the replacement of one or more parts as assemblies. Basic vehicle maintenance is a fundamental part of a mechanic's work in modern industrialized countries, while in others they are only consulted when a vehicle is already showing signs of malfunction. Education Automotive repair knowledge can be derived from on-the-job training, an apprenticeship program, vocational school, or university. Apprenticeship * Apprent ...

Russian Jews
The history of the Jews in Russia and areas historically connected with it goes back at least 1,500 years. Jews in Russia have historically constituted a large religious and ethnic diaspora; the Russian Empire at one time hosted the largest population of Jews in the world. Within these territories the primarily Ashkenazi Jewish communities of many different areas flourished and developed many of modern Judaism's most distinctive theological and cultural traditions, while also facing periods of anti-Semitic discriminatory policies and persecutions. Some have described a "renaissance" in the Jewish community inside Russia since the beginning of the 21st century.Renaissance of Jewish life in Russia November 23, 2001, By John ...

Russian Empire
The Russian Empire was an empire and the final period of the Russian monarchy from 1721 to 1917, ruling across large parts of Eurasia. It succeeded the Tsardom of Russia following the Treaty of Nystad, which ended the Great Northern War. The rise of the Russian Empire coincided with the decline of neighbouring rival powers: the Swedish Empire, the Polish–Lithuanian Commonwealth, Qajar Iran, the Ottoman Empire, and Qing China. It also held colonies in North America between 1799 and 1867. Covering an area of approximately , it remains the third-largest empire in history, surpassed only by the British Empire and the Mongol Empire; it ruled over a population of 125.6 million people per the 1897 Russian census, which was the only census carried out during the entire imperial period. Owing to its geographic extent across three continents at its peak, it featured great ethnic, linguistic, religious, and economic diversity. From the 10th–17th centuries, the land ...

Flerovium
Flerovium is a superheavy chemical element with symbol Fl and atomic number 114. It is an extremely radioactive synthetic element. It is named after the Flerov Laboratory of Nuclear Reactions of the Joint Institute for Nuclear Research in Dubna, Russia, where the element was discovered in 1998. The lab's name, in turn, honours Russian physicist Georgy Flyorov ( in Cyrillic, hence the transliteration of " yo" to "e"). IUPAC adopted the name on 30 May 2012. The name and symbol had previously been proposed for element 102 (nobelium), but was not accepted by IUPAC at that time. It is a transactinide in the p-block of the periodic table. It is in period 7; the heaviest known member of the carbon group, and the last element whose chemistry has been investigated. Initial chemical studies in 2007–2008 indicated that flerovium was unexpectedly volatile for a group 14 element; in preliminary results it even seemed to exhibit properties similar to noble gases. More recent results show ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
