Leonhard Euler (/ˈɔɪlər/OY-lər; German:[ˈleːɔnhaʁtˈʔɔʏlɐ]ⓘ, Swiss Standard German:[ˈleɔnhardˈɔʏlər]; 15 April 1707 – 18 September 1783) was a Swisspolymath who was active as a mathematician, physicist, astronomer, logician, geographer, and engineer. He founded the studies of graph theory and topology and made influential discoveries in many other branches of mathematics such as analytic number theory, complex analysis, and infinitesimal calculus. He also introduced much of modern mathematical terminology and notation, including the notion of a mathematical function. He is also known for his work in mechanics, fluid dynamics, optics, astronomy, and music theory. As a result, Euler has been described as a "universal genius" who "was fully equipped with almost unlimited powers of imagination, intellectual gifts and extraordinary memory".
Euler is regarded as arguably the most prolific contributor in the history of mathematics and science, and the greatest mathematician of the 18th century. Several great mathematicians who produced their work after Euler's death have recognised his importance in the field as shown by quotes attributed to many of them: Pierre-Simon Laplace expressed Euler's influence on mathematics by stating, "Read Euler, read Euler, he is the master of us all." Carl Friedrich Gauss wrote: "The study of Euler's works will remain the best school for the different fields of mathematics, and nothing else can replace it." His 866 publications and his correspondence are being collected in the Opera Omnia Leonhard Euler which, when completed, will consist of 81 quartos. He spent most of his adult life in Saint Petersburg, Russia, and in Berlin, then the capital of Prussia. (Full article...)
Born and raised in Georgia, in the Russian Empire, Ordzhonikidze joined the Bolsheviks at an early age and quickly rose within the ranks to become an important figure within the group. Arrested and imprisoned several times by the Russian police, he was in Siberian exile when the February Revolution began in 1917. Returning from exile, Ordzhonikidze took part in the October Revolution that brought the Bolsheviks to power. During the subsequent Civil War he played an active role as the leading Bolshevik in the Caucasus, overseeing the invasions of Azerbaijan, Armenia, and Georgia. He backed their union into the Transcaucasian Socialist Federative Soviet Republic (TSFSR), which helped form the Soviet Union in 1922 and served as the First Secretary of the TSFSR until 1926.

The terrain complicated battle tactics for both sides, but the Russians and the Austrians, having arrived in the area first, were able to overcome many of its difficulties by strengthening a causeway between two small ponds. They had also devised a solution to Frederick's deadly modus operandi, the oblique order. Although Frederick's troops initially gained the upper hand in the battle, his limited scouting, combined with the strong defensive preparations of the Allied troops, gave the Russians and Austrians an advantage. By afternoon, when the combatants were exhausted, fresh Austrian troops thrown into the fray secured the Allied victory. (Full article...)

Nadezhda Sergeyevna Alliluyeva (Russian: Надежда Сергеевна Аллилуева; 22 September [O.S. 9 September] 1901 – 9 November 1932) was the second wife of Joseph Stalin. She was born in Baku to a friend of Stalin, a fellow revolutionary, and was raised in Saint Petersburg. Having known Stalin from a young age, she married him when she was 17, and they had two children. Alliluyeva worked as a secretary for Bolshevik leaders, including Vladimir Lenin and Stalin, before enrolling at the Industrial Academy in Moscow to study synthetic fibres and become an engineer. She had health issues, which had an adverse impact on her relationship with Stalin. She also suspected he was unfaithful, which led to frequent arguments with him. On several occasions, Alliluyeva reportedly contemplated leaving Stalin, and after an argument, she fatally shot herself early in the morning of 9 November 1932. (Full article...)

The woolly mammoth (Mammuthus primigenius) is an extinct species of mammoth that lived from the Middle Pleistocene until its extinction in the Holocene epoch. It was one of the last in a line of mammoth species, beginning with the African Mammuthus subplanifrons in the early Pliocene. The woolly mammoth began to diverge from the steppe mammoth about 800,000 years ago in Siberia. Its closest extant relative is the Asian elephant. The Columbian mammoth (Mammuthus columbi) lived alongside the woolly mammoth in North America, and DNA studies show that the two hybridised with each other. Mammoth remains had long been known in Asia before they became known to Europeans. The origin of these remains was long a matter of debate and often explained as being remains of legendary creatures. The mammoth was identified as an extinct species of elephant by Georges Cuvier in 1796.
The appearance and behaviour of this species are among the best studied of any prehistoric animal because of the discovery of frozen carcasses in Siberia and North America, as well as skeletons, teeth, stomach contents, dung, and depiction from life in prehistoric cave paintings. The woolly mammoth was roughly the same size as modern African elephants. Males reached shoulder heights between 2.67 and 3.49 m (8 ft 9 in and 11 ft 5 in) and weighed between 3.9 and 8.2 t (3.8 and 8.1 long tons; 4.3 and 9.0 short tons). Females reached 2.3–2.6 m (7 ft 7 in – 8 ft 6 in) in shoulder heights and weighed between 2.8–4 t (2.8–3.9 long tons; 3.1–4.4 short tons). A newborn calf weighed about 90 kg (200 lb). The woolly mammoth was well adapted to the cold environments present during glacial periods, including the last ice age. It was covered in fur, with an outer covering of long guard hairs and a shorter undercoat. The colour of the coat varied from dark to light. The ears and tail were short to minimise frostbite and heat loss. It had long, curved tusks and four molars, which were replaced six times during the lifetime of an individual. Its behaviour was similar to that of modern elephants, and it used its tusks and trunk for manipulating objects, fighting, and foraging. The diet of the woolly mammoth was mainly grasses and sedges. Individuals could probably reach the age of 60. Its habitat was the mammoth steppe, which stretched across northern Eurasia and North America. (Full article...)
In mid- to late-19th-century Russia, Pyotr Ilyich Tchaikovsky and a group of composers known as The Five had differing opinions as to whether Russian classical music should be composed following Western or native practices. Tchaikovsky wanted to write professional compositions of such quality that they would stand up to Western scrutiny and thus transcend national barriers, yet remain distinctively Russian in melody, rhythm and other compositional characteristics. The Five, made up of composers Mily Balakirev, Alexander Borodin, César Cui, Modest Mussorgsky, and Nikolai Rimsky-Korsakov, sought to produce a specifically Russian kind of art music, rather than one that imitated older European music or relied on European-style conservatory training. While Tchaikovsky himself used folk songs in some of his works, for the most part he tried to follow Western practices of composition, especially in terms of tonality and tonal progression. Also, unlike Tchaikovsky, none of The Five were academically trained in composition; in fact, their leader, Balakirev, considered academicism a threat to musical imagination. Along with critic Vladimir Stasov, who supported The Five, Balakirev attacked relentlessly both the Saint Petersburg Conservatory, from which Tchaikovsky had graduated, and its founder Anton Rubinstein, orally and in print.
As Tchaikovsky had become Rubinstein's best-known student, he was initially considered by association as a natural target for attack, especially as fodder for Cui's printed critical reviews. This attitude changed slightly when Rubinstein left the Saint Petersburg musical scene in 1867. In 1869 Tchaikovsky entered into a working relationship with Balakirev; the result was Tchaikovsky's first recognized masterpiece, the fantasy-overture Romeo and Juliet, a work which The Five wholeheartedly embraced. When Tchaikovsky wrote a positive review of Rimsky-Korsakov's Fantasy on Serbian Themes he was welcomed into the circle, despite concerns about the academic nature of his musical background. The finale of his Second Symphony, nicknamed the Little Russian, was also received enthusiastically by the group on its first performance in 1872. (Full article...)
Poltava was salvaged after the Japanese captured Port Arthur and incorporated into the Imperial Japanese Navy. The ship, renamed Tango in Japanese service, participated in the Battle of Tsingtao in late 1914, during World War I. She was sold back to the Russians in 1916 and renamed Chesma as her original name was in use by another battleship. The ship became the flagship of the Russian Arctic Flotilla in 1917, and her crew supported the Bolsheviks later that year. Chesma was seized by the British in early 1918 when they intervened in the Russian Civil War, abandoned by them when they withdrew and scrapped by the Soviets in 1924. (Full article...)

Eduard Anatolyevich Streltsov (Russian: Эдуа́рд Анато́льевич Стрельцо́в, IPA:[ɨdʊˈartɐnɐˈtolʲjɪvʲitɕstrʲɪlʲˈtsof]ⓘ; 21 July 1937 – 22 July 1990) was a Soviet footballer who played as a forward for Torpedo Moscow and the Soviet national team during the 1950s and 1960s. A powerful and skilful attacking player, he scored the fourth-highest number of goals for the Soviet Union and has been called "the greatest outfield player Russia has ever produced". He is sometimes dubbed "the Russian Pelé".
Born and raised in east Moscow, Streltsov joined Torpedo at the age of 16 in 1953 and made his international debut two years later. He was part of the squad that won the gold medal at the 1956 Melbourne Olympics, and came seventh in the 1957 Ballon d'Or. The following year, his promising career was interrupted by allegations of sexual assault shortly before the 1958 World Cup. Soviet authorities pledged he could still play if he admitted his guilt, after which he confessed, but was instead prosecuted and sentenced to twelve years of forced labour under the Gulag system (abolished in 1960 and replaced by prisons). The conviction was highly controversial, with many pointing to conflicts between Streltsov and government officials. (Full article...)
The sculpture depicts a female personification of Russia, commonly referred to as Mother Russia. She wears a windswept shawl resembling wings, and holds a sword aloft in her right hand. Her left hand is extended outward, as she calls upon the Soviet people to battle. The statue was originally planned to be made of granite and to stand only 30 metres (98 ft) tall, with a design consisting of a Red Army soldier genuflecting and placing a sword before Mother Russia holding a folded banner. However, the design was changed in 1961 to be a large concrete structure at nearly double the height, a decision that was subject to criticism from Soviet military officials and writers. It was inspired by the Winged Victory of Samothrace, an ancient Greek sculpture of the goddess of victory, Nike. (Full article...)
Although musically precocious, Tchaikovsky was educated for a career as a civil servant as there was little opportunity for a musical career in Russia at the time and no public music education system. When an opportunity for such an education arose, he entered the nascent Saint Petersburg Conservatory, from which he graduated in 1865. The formal Western-oriented teaching Tchaikovsky received there set him apart from composers of the contemporary nationalist movement embodied by the Russian composers of The Five, with whom his professional relationship was mixed.

Tintin in the Land of the Soviets (French: Tintin au pays des Soviets) is the first volume of The Adventures of Tintin, the comics series by Belgian cartoonist Hergé. Commissioned by the conservative Belgian newspaper Le Vingtième Siècle as anti-communistsatire for its children's supplement Le Petit Vingtième, it was serialised weekly from January 1929 to May 1930 before being published in a collected volume by Éditions du Petit Vingtième in 1930. The story tells of young Belgian reporter Tintin and his dog Snowy, who are sent to the Soviet Union to report on Stalin's government. Knowing of his intentions, however, the secret police of the OGPU are sent to hunt him down.
Bolstered by publicity stunts, Land of the Soviets was a commercial success in Belgium, and also witnessed serialisation in France and Switzerland. Hergé continued The Adventures of Tintin with Tintin in the Congo, and the series became a defining part of the Franco-Belgian comics tradition. Damage to the original plates prevented republication of the book for several decades, while Hergé later expressed embarrassment at the crudeness of the work. As he began to redraw his earlier Adventures in second, colour versions from 1942 onward, he decided against doing so for Land of the Soviets; it was the only completed Tintin story that Hergé did not reproduce in colour. Growing demand among fans of the series resulted in the production of unauthorised copies of the book in the 1960s, with the first officially sanctioned republication appearing in 1969, after which it was translated into several other languages, including English. Critical reception of the work has been largely negative, and several commentators on The Adventures of Tintin have described Land of the Soviets as one of Hergé's weakest works. (Full article...)

Marshal Mortier at the battle of Durenstein in 1805, by Auguste Sandoz
The Battle of Dürenstein (German: Schlacht bei Dürnstein; also known as Dürrenstein, Dürnstein and Diernstein) or the Battle of Krems (Russian: Сражение при Кремсе), on 11 November 1805, was an engagement in the Napoleonic Wars during the War of the Third Coalition. Dürenstein (modern Dürnstein), Austria, is located in the Wachau valley, on the river Danube, 73 kilometers (45 mi) upstream from Vienna, Austria. The river makes a crescent-shaped curve between Dürnstein and nearby Krems an der Donau, and the battle was fought in the flood plain between the river and the mountains.
At Dürenstein, a combined force of Russian and Austrian troops trapped a French division commanded by Théodore Maxime Gazan. The French division was part of the newly created VIII Corps, the so-called Corps Mortier, under command of Édouard Mortier. In pursuing the Austrian retreat from Bavaria, Mortier had over-extended his three divisions along the north bank of the Danube. Mikhail Kutuzov, commander of the Coalition force, enticed Mortier to send Gazan's division into a trap and French troops were caught in a valley between two Russian columns. They were rescued by the timely arrival of a second division, under command of Pierre Dupont de l'Étang. The battle extended well into the night, after which both sides claimed victory. The French lost more than a third of their participants, and Gazan's division experienced over 40 percent losses. The Austrians and Russians also had heavy losses—close to 16 percent—but perhaps the most significant was the death in action of Johann Heinrich von Schmitt, one of Austria's most capable chiefs of staff.

Yuri Gagarin (9 March 1934 – 27 March 1968) was a Soviet Air Forces pilot and cosmonaut who became the first human to journey into outer space; his capsule, Vostok 1, completed a single orbit of Earth on 12 April 1961. Gagarin became an international celebrity and was awarded many medals and titles, including Hero of the Soviet Union, his nation's highest honour. In 1967, he served as a member of the backup crew for the ill-fated Soyuz 1 mission, after which the Russian authorities, fearing for the safety of such an iconic figure, banned him from further spaceflights. However, he was killed the following year, when the MiG-15 training jet that he was piloting with his flight instructor Vladimir Seryogin crashed near the town of Kirzhach.
This photograph of Gagarin, dated July 1961, was taken at a press conference during a visit to Finland approximately three months after his spaceflight.
The Chesme Column is a victory column in the Catherine Park at the Catherine Palace, a former Russian royal residence in Tsarskoye Selo, a suburb of Saint Petersburg. It was erected to commemorate three Russian naval victories in the 1768–1774 Russo-Turkish War, including the Battle of Chesma in 1770. The column is made from three pieces of white-and-pink marble; decorated with the rostra of three ships' bows, and crowned by a triumphal bronze statue depicting a Russian eagle trampling a crescent moon, the symbol of Turkey. Bronze plaques on three sides of the pedestal depict scenes from the battles, and the campaign is described on the plaque on the fourth side.
This photo of the Nilov Monastery on Stolobny Island in Tver Oblast, Russia, was taken by Sergey Prokudin-Gorsky in 1910 before the advent of colour photography. His process used a camera that took a series of monochrome pictures in rapid sequence, each through a different coloured filter. By projecting all three monochrome pictures using correctly coloured light, it was possible to reconstruct the original colour scene.
Although James Clerk Maxwell made the first color photograph in 1861, the results were far from realistic until Prokudin-Gorsky perfected the technique with a series of improvements around 1905. His process used a camera that took a series of monochrome pictures in rapid sequence, each through a different colored filter. Prokudin-Gorskii then went on to document much of the country of Russia, travelling by train in a specially equipped darkroomrailroad car.
Ivan Goremykin (1839–1917) was a Russian prime minister during World War I. A politician with archconservative views, after some time in the Ministry of Justice, he transferred to the Ministry of the Interior in 1891. He held the rank of prime minister from May to July 1906 and again from 1914 to 1916; during both terms his effectiveness was strongly limited by opposition from the State Duma. In the aftermath of the October Revolution, Goremykin was recognized as a member of the Tsarist government and killed by a street mob.

Maslenitsa, a 1919 painting depicting the carnival of the same name, which takes place the last week before Great Lent. The painting encompasses a broad range of things associated with Russia, such as snowy winter weather, a troika, an Orthodox church with onion domes. Painted in the aftermath of the October Revolution, the canvas was intended as a farewell to the unspoilt "Holy Russia" of yore.
An aerial view of the Field of Mars, a large park in central Saint Petersburg, Russia, pictured in 2016. It is named after Mars, the Roman god of war. The park's history goes back to the 18th century, when it was converted from bogland and named the Grand Meadow. Later, it was the setting for celebrations to mark Russia's victory over Sweden in the Great Northern War. Its next name, the Tsaritsyn Meadow, appears after the royal family commissioned Francesco Bartolomeo Rastrelli to build the Summer Palace for Empress Elizabeth. It became the Field of Mars during the reign of Paul I. Towards the end of the 18th century, the park became a military drill ground, where they erected monuments commemorating the victories of the Russian Army and where parades and military exercises took place regularly. After the February Revolution in 1917, the Field of Mars became a memorial area for the revolution's honoured dead. In the summer of 1942, as the city was besieged by the German army in the Siege of Leningrad, the park was covered with vegetable gardens to supply food. An eternal flame was lit in the centre of the park in 1957, in memory of the victims of various wars and revolutions.
Leo Tolstoy (1828–1910) was a Russian writer who is regarded as one of the world's greatest novelists. He is best known for War and Peace (1869) and Anna Karenina (1877), often cited as pinnacles of realist fiction. Born to an aristocratic family on 9 September [O.S. 28 August] 1828, Tolstoy was orphaned when he was young. He studied at Kazan University, but this was not a success, and he left university without completing his degree. During this time, he began to write and published his first novel, Childhood, in 1852. Tolstoy later served at the Siege of Sevastopol during the Crimean War, and was appalled by the number of deaths and left at the conclusion of the war. He spent the remainder of his life writing whilst also marrying and starting a family. In the 1870s he converted to a form of fervent Christian anarchism.
January 25, 1721 - Peter established the Holy Synod, a body of ten clergymen chaired by a secular official, that was to head the Russian Orthodox Church in lieu of the Patriarch of Moscow.
January 28, 1725 - Peter died of urinary problems. He failed to name a successor; one of Peter's closest advisers, Aleksandr Menshikov, convinced the Imperial Guard to declare in favor of Peter's wife Catherine I.
Udmurt cuisine consists of the cuisine of Udmurtia and the Udmurt people, and is characterized by the rich use of local foods. Old traditions include foods made from grains and flour, especially milled rye, barley, wheat, and buckwheat. Meat, vegetables and black bread are staple foods in Udmurt cuisine. Additional foods include pelmeni, pancakes, pastries and small tarts. Milk is a scarce commodity, and that which exists is often made into ayran, a type of sour milk.
The Udmurt people have historically been involved in cattle breeding, agricultural production and hunting. Beekeeping is a common practice among the Udmurts and other groups in the area, and pig farming also exists. Potatoes, vegetables and flax are produced in significant quantities in Udmurtia. For total agricultural production in Russia, Udmurtia was ranked as 33rd. (Full article...)

Ukraine finalizes military reforms aimed at recruiting 18- to 25-year-olds to the armed forces, penalizing draft dodgers, and lowering the minimum compulsory military service age to 25 from 27. (The Kyiv Independent)
Russia has made its choice in favor of democracy. Fourteen years ago, independently, without any pressure from outside, it made that decision in the interests of itself and interests of its people -- of its citizens. This is our final choice, and we have no way back. There can be no return to what we used to have before. And the guarantee for this is the choice of the Russian people, themselves. No, guarantees from outside cannot be provided. This is impossible. It would be impossible for Russia today. Any kind of turn towards totalitarianism for Russia would be impossible, due to the condition of the Russian society.
