caption_attribution_description: English: Russia's Mir space station is backdropped over the blue and white planet Earth in this medium range photograph recorded during the final fly-around of the members of the fleet of NASA's shuttles. Seven crew members, including Andrew S.W. Thomas, were aboard the Space Shuttle Discovery when the photo was taken; and two of his former cosmonaut crewmates remained aboard Mir. Thomas ended up spending 141 days in space on this journey, including time aboard Space Shuttles Endeavour and Discovery, which transported him to and from Mir.
context_page_description: Russia, or the Russian Federation, is a transcontinental country located in Eastern Europe and Northern Asia. Covering an area of 17,125,200 square kilometres, it is the largest country in the world by area, spanning more than one-eighth of the Earth's inhabited land area, stretching eleven time zones, and bordering 16 sovereign nations. The territory of Russia extends from the Baltic Sea in the west to the Pacific Ocean in the east, and from the Arctic Ocean in the north to the Black Sea and the Caucasus in the south. With 146.7 million inhabitants living in the country's 85 federal subjects, Russia is the most populous nation in Europe and the ninth-most populous nation in the world. Russia's capital and largest city is Moscow; other major urban areas include Saint Petersburg, Novosibirsk, Yekaterinburg, Nizhny Novgorod, Kazan, Chelyabinsk and Samara.
  The East Slavs emerged as a recognisable group in Europe between the 3rd and 8th centuries AD. The medieval state of Rus' arose in the 9th century. In 988 it adopted Orthodox Christianity from the Byzantine Empire, beginning the synthesis of Byzantine and Slavic cultures that defined Russian culture for the next millennium.
context_section_description: Science and technology in Russia blossomed since the Age of Enlightenment, when Peter the Great founded the Russian Academy of Sciences and Saint Petersburg State University, and polymath Mikhail Lomonosov established the Moscow State University, paving the way for a strong native tradition in learning and innovation. In the 19th and 20th centuries the country produced a large number of notable scientists and inventors.
  The Russian physics school began with Lomonosov who proposed the law of conservation of matter preceding the energy conservation law. Russian discoveries and inventions in physics include the electric arc, electrodynamical Lenz's law, space groups of crystals, photoelectric cell, superfluidity, Cherenkov radiation, electron paramagnetic resonance, heterotransistors and 3D holography. Lasers and masers were co-invented by Nikolai Basov and Alexander Prokhorov, while the idea of tokamak for controlled nuclear fusion was introduced by Igor Tamm, Andrei Sakharov and Lev Artsimovich, leading eventually the modern international ITER project, where Russia is a party.
  Since the time of Nikolay Lobachevsky (the "Copernicus of Geometry" who pioneered the non-Euclidean geometry) and a prominent tutor Pafnuty Chebyshev, the Russian mathematical school became one of the most influential in the world. Chebyshev's students included Aleksandr Lyapunov, who founded the modern stability theory, and Andrey Markov who invented the Markov chains. In the 20th century Soviet mathematicians, such as Andrey Kolmogorov, Israel Gelfand, and Sergey Sobolev, made major contributions to various areas of mathematics. Nine Soviet/Russian mathematicians were awarded with the Fields Medal, a most prestigious award in mathematics. Recently Grigori Perelman was offered the first ever Clay Millennium Prize Problems Award for his final proof of the Poincaré conjecture in 2002.
  Russian chemist Dmitry Mendeleev invented the Periodic table, the main framework of modern chemistry. Aleksandr Butlerov was one of the creators of the theory of chemical structure, playing a central role in organic chemistry. Russian biologists include Dmitry Ivanovsky who discovered viruses, Ivan Pavlov who was the first to experiment with the classical conditioning, and Ilya Mechnikov who was a pioneer researcher of the immune system and probiotics.
  Many Russian scientists and inventors were émigrés, like Igor Sikorsky, who built the first airliners and modern-type helicopters; Vladimir Zworykin, often called the father of television; chemist Ilya Prigogine, noted for his work on dissipative structures and complex systems; Nobel Prize-winning economists Simon Kuznets and Wassily Leontief; physicist Georgiy Gamov (an author of the Big Bang theory) and social scientist Pitirim Sorokin. Many foreigners worked in Russia for a long time, like Leonard Euler and Alfred Nobel.
  Russian inventions include arc welding by Nikolay Benardos, further developed by Nikolay Slavyanov, Konstantin Khrenov and other Russian engineers. Gleb Kotelnikov invented the knapsack parachute, while Evgeniy Chertovsky introduced the pressure suit. Alexander Lodygin and Pavel Yablochkov were pioneers of electric lighting, and Mikhail Dolivo-Dobrovolsky introduced the first three-phase electric power systems, widely used today. Sergei Lebedev invented the first commercially viable and mass-produced type of synthetic rubber. The first ternary computer, Setun, was developed by Nikolay Brusentsov.
  In the 20th century a number of prominent Soviet aerospace engineers, inspired by the fundamental works of Nikolai Zhukovsky, Sergei Chaplygin and others, designed many hundreds of models of military and civilian aircraft and founded a number of KBs (Construction Bureaus) that now constitute the bulk of Russian United Aircraft Corporation. Famous Russian aircraft include the civilian Tu-series, Su and MiG fighter aircraft, Ka and Mi-series helicopters; many Russian aircraft models are on the list of most produced aircraft in history.
  Famous Russian battle tanks include T34, the most heavily produced tank desig
