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 ...

Russian–American
Russian Americans ( rus, русские американцы, r=russkiye amerikantsy, p= ˈruskʲɪje ɐmʲɪrʲɪˈkant͡sɨ) are Americans of full or partial Russian ancestry. The term can apply to recent Russian immigrants to the United States, as well as to those who settled in the 19th-century Russian possessions in northwestern America. Russian Americans comprise the largest Eastern European and East Slavic population in the U.S., the second-largest Slavic population generally, the nineteenth-largest ancestry group overall, and the eleventh-largest from Europe. In the mid-19th century, waves of Russian immigrants fleeing religious persecution settled in the U.S., including Russian Jews and Spiritual Christians. These groups mainly settled in coastal cities, including Alaska, Brooklyn (New York City) on the East Coast, and Los Angeles, San Francisco, and Portland, Oregon, on the West Coast, as well as in Great Lakes cities, such as Chicago and Cleveland.

Russian Nationalism
Russian nationalism is a form of nationalism that promotes Russian cultural identity and unity. Russian nationalism first rose to prominence in the early 19th century, and from its origin in the Russian Empire, to its repression during early Bolshevik rule, and its revival in the Soviet Union, it was closely related to pan-Slavism. The definition of Russian national identity within Russian nationalism has been characterized in different ways. In ethnic terms one including asserting that those identified as ethnic Russians are the Russian nation, another is the All-Russian nation concept developed in the Russian Empire that views Russians as having three sub-national groups within it including Great Russians (those commonly identified as ethnic Russians today), Little Russians (Ukrainians), and White Russians ( Belarusians). Russian nationalists have identified Russia as the main successor of the Kievan Rus' and typically view the arising of separate national identities of Bel ...

Psychology
Psychology is the scientific study of mind and behavior. Psychology includes the study of conscious and unconscious phenomena, including feelings and thoughts. It is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.Fernald LD (2008)''Psychology: Six perspectives'' (pp.12–15). Thousand Oaks, CA: Sage Publications.Hockenbury & Hockenbury. Psychology. Worth Publishers, 2010. Ψ (''psi''), the first letter of the Greek word ''psyche'' from which the term psychology is derived (see below), is commonly associated with the science. A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as behavioral or cognitive scientists. Some psyc ...

Vought-Sikorsky VS-300
The Vought-Sikorsky VS-300 (or S-46) is an American single-engine helicopter designed by Igor Sikorsky. It had a single three-blade rotor originally powered by a 75 horsepower (56 kW) engine. The first "free" flight of the VS-300 was on 13 May 1940.Munson 1968, p. 111. The VS-300 was the first successful single lifting rotor helicopter in the United States and the first successful helicopter to use a single vertical-plane tail rotor configuration for antitorque. With floats attached, it became the first practical amphibious helicopter. Design and development Igor Sikorsky's quest for a practical helicopter began in 1938, when as the Engineering Manager of the Vought-Sikorsky Division of United Aircraft Corporation, he was able to convince the directors of United Aircraft that his years of study and research into rotary-wing flight problems would lead to a breakthrough. His first experimental machine, the VS-300, was test flown by Sikorsky on 14 September 1939, tethered by c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flying Boats
A flying boat is a type of fixed-winged seaplane with a hull, allowing it to land on water. It differs from a floatplane in that a flying boat's fuselage is purpose-designed for floatation and contains a hull, while floatplanes rely on fuselage-mounted floats for buoyancy. Though the fuselage provides buoyancy, flying boats may also utilize under-wing floats or wing-like projections (called sponsons) extending from the fuselage for additional stability. Flying boats often lack landing gear which would allow them to land on the ground, though many modern designs are convertible amphibious aircraft which may switch between landing gear and flotation mode for water or ground takeoff and landing. Ascending into common use during the First World War, flying boats rapidly grew in both scale and capability during the interwar period, during which time numerous operators found commercial success with the type. Flying boats were some of the largest aircraft of the first half of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pan American Airways
Pan American World Airways, originally founded as Pan American Airways and commonly known as Pan Am, was an American airline that was the principal and largest international air carrier and unofficial overseas flag carrier of the United States for much of the 20th century. It was the first airline to fly worldwide and pioneered numerous innovations of the modern airline industry such as jumbo jets, and computerized reservation systems. Until its dissolution in 1991, Pan Am "epitomized the luxury and glamour of intercontinental travel", and it remains a cultural icon of the 20th century, identified by its blue globe logo ("The Blue Meatball"), the use of the word "Clipper" in its aircraft names and call signs, and the white uniform caps of its pilots. Founded in 1927 by two former U.S. Army Air Corps majors, Pan Am began as a scheduled airmail and passenger service flying between Key West, Florida, and Havana, Cuba. Under the leadership of American entrepreneur Juan Trippe, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sikorsky Aircraft
Sikorsky Aircraft is an American aircraft manufacturer based in Stratford, Connecticut. It was established by aviation pioneer Igor Sikorsky in 1923 and was among the first companies to manufacture helicopters for civilian and military use. Previously owned by United Technologies Corporation, in November 2015 Sikorsky was sold to Lockheed Martin. History On 5 March 1923, the Sikorsky Aero Engineering Corporation was founded near Roosevelt Field, New York, by Igor Sikorsky, an immigrant to the United States who was born in Kyiv. In 1925, the company name was changed to Sikorsky Manufacturing Company. After the success of the Sikorsky S-38">S-38, the company was reorganized as the Sikorsky Aviation Corporation with capital of $5,000,000, allowing the purchase of land and the building of a modern aircraft factory in Stratford. In 1929, the company moved to Stratford, Connecticut, and it became a part of United Aircraft and Transport Corporation (later United Technologies Corporatio ...

Sikorsky S-6
The Sikorsky S-6 was a Russian single engine experimental aircraft similar to the S-5, built in 1911 by Igor Sikorsky. Design and development Construction of the first S-6 was started in August 1911. The three bay biplane was powered by an Argus 4-cylinder water-cooled engine producing . Initial flight tests in late November were disappointing, revealing a long take-off run and poor climb performance. Sikorsky disassembled the aircraft and took it home where substantial modifications were undertaken, including lengthening the wingspan and reducing aerodynamic drag by enclosing the fuselage with wood veneer. Ailerons on the lower wing were removed and strut bracing wires were arranged in pairs with wooden spacers between them, further reducing drag. Sikorsky now called the machine the S-6-A and it exhibited remarkable improvement. During one flight with three men on board the aircraft registered a speed of , exceeding the world record at that time and in February 1912 the ...

Sikorsky S-5
The Sikorsky S-5 was an early Russian single seat biplane design by Igor Sikorsky, completed in late April 1911. Design and development The S-5 was powered by a Argus water-cooled engine turning a propeller Sikorsky designed and built himself. The fabric covering the wooden wings was tightened with pure alcohol and glue mixed with boiling water. The fuselage structure was left exposed. Instead of separate levers to control the elevator and ailerons as in his previous aircraft, Sikorsky designed a single control lever with a wheel allowing control of pitch and roll. This "control column" included a button switch to momentarily deactivate the ignition thereby controlling engine power. The rudder controls were reversed, because it better suited Sikorsky's tactility of the machine. Operational history The S-5 was tested in a series of 20 to 30-second straight-line flights, over a period of three weeks, before the designer was able to make what he called his first real flight ...
