Russia, is a country in northern Eurasia (Europe and Asia together). It is a semi-presidential republic, comprising 83 federal subjects. Russia shares land borders with the following countries (from northwest to southeast): Norway, Finland, Estonia, Latvia, Lithuania (via Kaliningrad Oblast), Poland (via Kaliningrad Oblast), Belarus, Ukraine, Georgia, Azerbaijan, Kazakhstan, China, Mongolia and the Democratic People's Republic of Korea. It also has maritime borders with Japan (by the Sea of Okhotsk), the Republic of Korea (by the Sea of Japan), Sweden (by the Baltic Sea), Turkey (by the Black Sea), and the United States (by the Bering Strait). At 17,075,400 square kilometres (6,592,800 sq mi), Russia is, in area, by far the largest country in the world, covering more than an eighth of the Earth’s land area; with 142 million people, it is the ninth largest by population. It extends across the whole of northern Asia and 40% of Europe, spanning 11 time zones, and incorporating a wide range of environments and landforms. Russia has the world's largest reserves of mineral and energy resources, and is considered an energy superpower. It has the world's largest forest reserves and its lakes contain approximately one-quarter of the world's unfrozen fresh water.
Russia's 160 ethnic groups speak some 100 languages. According to the 2002 census, 142.6 million people speak Russian, followed by Tatar with 5.3 million and Ukrainian with 1.8 million speakers. Russian is the only official state language, but the Constitution gives the individual republics the right to make their native language co-official next to Russian. Despite its wide dispersal, the Russian language is homogeneous throughout Russia. Russian is the most geographically widespread language of Eurasia and the most widely spoken Slavic language.Russian belongs to the Indo-European language family and is one of the living members of the East Slavic languages; the others being Belarusian and Ukrainian (and possibly Rusyn). Written examples of Old East Slavic (Old Russian) are attested from the 10th century onwards.
Over a quarter of the world's scientific literature is published in Russian. Russian is also applied as a means of coding and storage of universal knowledge—60–70% of all world information is published in the English and Russian languages. The language is one of the six official languages of the United Nations.
Russia's large number of ethnic groups have distinctive traditions of folk music. Music in 19th century Russia was defined by the tension between classical composer Mikhail Glinka and his followers, who embraced Russian national identity and added religious and folk elements to their compositions, and the Russian Musical Society led by composers Anton and Nikolay Rubinstein, which was musically conservative. The later Romantic tradition of Tchaikovsky, one of the greatest composers of the Romantic era whose music has come to be known and loved for its distinctly Russian character as well as its rich harmonies and stirring melodies, was brought into the 20th century by Sergei Rachmaninoff, one of the last great champions of the Romantic style of European classical music.
World-renowned composers of the 20th century included Scriabin, Stravinsky, Rachmaninoff, Prokofiev, and Shostakovich. During most of the Soviet Era, music was highly scrutinized and kept within a conservative, accessible idiom in conformity with the Stalinist policy of socialist realism. Soviet and Russian conservatories have turned out generations of world-renowned soloists. Among the best known are violinists David Oistrakh and Gidon Kremer, cellist Mstislav Rostropovich, pianists Vladimir Horowitz, Sviatoslav Richter and Emil Gilels, and vocalist Galina Vishnevskaya.Russian composer Pyotr Ilyich Tchaikovsky composed the world's most famous works of ballet—Swan Lake, The Nutcracker, and Sleeping Beauty. During the early 20th century, Russian dancers Anna Pavlova and Vaslav Nijinsky rose to fame, and the business man Sergei Diaghilev and his Ballets Russes' travels abroad profoundly influenced the development of dance worldwide. Soviet ballet preserved the perfected 19th century traditions, and the Soviet Union's choreography schools produced one internationally famous star after another, including Maya Plisetskaya, Rudolf Nureyev, and Mikhail Baryshnikov. The Bolshoi Ballet in Moscow and the Kirov in Saint Petersburg remain famous throughout the world.
