Euler is credited for popularizing the Greek letter (lowercase pi) to denote the ratio of a circle's circumference to its diameter, as well as first using the notation for the value of a function, the letter to express the imaginary unit, the Greek letter (capital sigma) to express summations, the Greek letter (capital delta) for finite differences, and lowercase letters to represent the sides of a triangle while representing the angles as capital letters. He gave the current definition of the constant , the base of the natural logarithm, now known as Euler's number. Euler made contributions to applied mathematics and engineering, such as his study of ships which helped navigation, his three volumes on optics contributed to the design of microscopes and telescopes, and he studied the bending of beams and the critical load of columns.

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 debated and often explained as being remains of legendary creatures. The mammoth was identified as an extinct elephant species 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...)
Due to the length of the front lines created by the German 1942 summer offensive, which had aimed at taking the Caucasus oil fields and the city of Stalingrad, German and other Axis forces were over-extended. The German decision to transfer several mechanized divisions from the Soviet Union to Western Europe exacerbated their situation. Furthermore, Axis units in the area were depleted by months of fighting, especially those which had taken part in the struggle for Stalingrad. The Germans could only count on the XXXXVIII Panzer Corps, which had the strength of a single panzer division, and the 29th Panzergrenadier Division as reserves to bolster their Romanian allies guarding the German Sixth Army's flanks. These Romanian armies lacked the heavy equipment to deal with Soviet armor. In contrast, the Red Army deployed over one million personnel for the offensive. Soviet troop movements were not without problems: concealing their build-up proved difficult, and Soviet units commonly arrived late due to logistical issues. Operation Uranus was first postponed by the Soviet high command (Stavka) from 8 to 17 November, then to 19 November. (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.

At the beginning of the Russo-Japanese War of 1904–1905, Petropavlovsk took part in the Battle of Port Arthur, where she was lightly damaged by Japanese shells and failed to score any hits in return. On 13 April 1904, the ship sank after striking one or more mines near Port Arthur, in northeast China. Casualties numbered 27 officers and 652 enlisted men, including Vice AdmiralStepan Makarov, the commander of the squadron, and the war artistVasily Vereshchagin. The arrival of the competent and aggressive Makarov after the Battle of Port Arthur had boosted Russian morale, which plummeted after his death. (Full article...)

Rostislav between 1907 and 1916.
Rostislav was a pre-dreadnought battleship built by the Nikolaev Admiralty Shipyard in the 1890s for the Black Sea Fleet of the Imperial Russian Navy. She was conceived as a small, inexpensive coastal defence ship, but the Navy abandoned the concept in favor of a compact, seagoing battleship with a displacement of 8,880 long tons (9,022 t). Poor design and construction practices increased her actual displacement by more than 1,600 long tons (1,626 t). Rostislav became the world's first capital ship to burn fuel oil, rather than coal. Her combat ability was compromised by the use of 10-inch (254 mm) main guns instead of the de facto Russian standard of 12 inches (305 mm).
Her hull was launched in September 1896, but non-delivery of the ship's main guns delayed her maiden voyage until 1899 and her completion until 1900. In May 1899 Rostislav became the first ship of the Imperial Navy to be commanded by a member of the House of Romanov, Captain Alexander Mikhailovich. From 1903 to 1912 the ship was the flagship of the second-in-command of the Black Sea Fleet. During the 1905 Russian Revolution her crew was on the verge of mutiny, but ultimately remained loyal to the regime, and actively suppressed the mutiny of the cruiser Ochakov. (Full article...)

The Polish architect Władysław Horodecki originally constructed the House with Chimaeras for use as his own upmarket apartment building during 1901–02. However, as the years went by, Horodecki eventually had to sell the building due to financial troubles, after which it changed ownership numerous times before finally being occupied by an official Communist Partypolyclinic until the early 2000s. When the building was vacated, its interior and exterior decor were fully reconstructed and restored according to Horodecki's original plans. (Full article...)
Anna Pavlovna Filosofova (Russian: Анна Павловна Философова; néeDiaghileva; 5 April 1837 – 17 March 1912) was a major Russian feminist and activist of the 19th and early 20th centuries.
Born into a wealthy, noble family, she married Vladimir Filosofov at a young age; they had six children. Initially concerned with the plight of serfs, Filosofova became a feminist in the late 1850s after joining the salon of Maria Trubnikova, who educated her on the subject. Alongside Trubnikova and Nadezhda Stasova, Filosofova was one of the earliest leaders of the Russian women's movement. Together, the three friends and allies were referred to as the "triumvirate". They founded and led several charitable organizations designed to promote women's cultural and economic independence, such as the Society for Cheap Lodgings and Other Benefits for the Citizens of St. Petersburg. Filosofova served as the president of that organization for several years. (Full article...)
At the 2008 NHL Entry Draft, Filatov was selected sixth overall by the Blue Jackets. Filatov was the top-ranked European skater by the NHL Central Scouting Bureau. Filatov played two seasons with the Blue Jackets organization. During the 2009–10 season, Filatov was unhappy with his situation in Columbus and was loaned to CSKA Moscow for the remainder of the season. At the 2011 NHL Entry Draft, the Blue Jackets then traded him to Ottawa in exchange for a third-round draft pick. In December 2011, the Senators loaned Filatov to CSKA Moscow for the balance of the 2011–12 season. The following season, Filatov signed with Salavat Yulaev. The Senators chose not to tender Filatov a qualifying offer, making him a free agent. (Full article...)
Nihonium was first reported to have been created in experiments carried out between 14 July and 10 August 2003, by a Russian–American collaboration at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, working in collaboration with the Lawrence Livermore National Laboratory in Livermore, California, and on 23 July 2004, by a team of Japanese scientists at Riken in Wakō, Japan. The confirmation of their claims in the ensuing years involved independent teams of scientists working in the United States, Germany, Sweden, and China, as well as the original claimants in Russia and Japan. In 2015, the IUPAC/IUPAP Joint Working Party recognised the element and assigned the priority of the discovery and naming rights for the element to Riken. The Riken team suggested the name nihonium in 2016, which was approved in the same year. The name comes from the common Japanese name for Japan (日本, nihon). (Full article...)

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...)

The Sukhoi Superjet 100 is a modern fly-by-wiretwin-engineregional jet with 8 to 108 passenger seats. Development began in 2000; the aircraft had its maiden flight on 19 May 2008 and entered commercial service on 21 April 2011. This aircraft is seen flying off the coast of Italy near Sanremo.
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.
An Alaskan parchment scrip banknote in the denomination of 1 ruble, printed on vellum or parchment by the Russian-American Company. On the obverse, the horizontal text immediately beneath the double-headed eagle reads "Seal of the Russian American Company". The oval text reads "under august protection of His Imperial Majesty", and under the oval is the value of the note "one ruble".
Alaskan parchment scrip was used as a form of company scrip in Alaska when it was a possession of the Russian Empire. In circulation from 1816 to 1867, such scrip could be printed on vellum, parchment, or pinniped skin. Denominations of 10, 25, 50 kopecks and 1, 5, 10, and 25 rubles were issued.
Kikin Hall, commissioned by Alexander Kikin in 1714, is one of the oldest buildings in Saint Petersburg. Incomplete at the time of Kikin's execution, the building was seized by the Russian crown and used for a variety of purposes. In the 1950s, Irina Benois arranged for the restoration of the dilapidated building. It is now home to a music school.

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.
A late nineteenth-century photochrom of a reindeer sled, Arkhangelsk, Russia. Reindeer have been herded for centuries by several Arctic and Subarctic people including the Sami and the Nenets. They are raised for their meat, hides, antlers and, to a lesser extent, for milk and transportation.
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.
The Portrait of Chaliapin is an oil-on-canvas painting by Boris Kustodiev, produced in 1921. Feodor Chaliapin was a Russian opera singer; possessing a deep and expressive bass voice, he enjoyed an important international career at major opera houses. He is depicted here wearing an expensive fur coat, which had come from a Soviet warehouse containing items confiscated from rich people during the Russian Revolution, and which he had received in lieu of payment for a performance. The background shows festivities at the traditional folk holiday of Maslenitsa. Dressed in a smart suit and holding a cane, Chaliapin is portrayed as having risen above his contemporaries. His favourite dog is at his feet and, at the bottom left, his two daughters stroll on the festive square in front of a poster promoting his concert. This copy of the painting is in the collection of the Russian Museum in Saint Petersburg.
A painting depicting Ivan Tsarevich, one of the main heroes of Russian folklore, riding a magic carpet after having captured the Firebird, which he keeps in a cage. This work was Viktor Vasnetsov's first attempt at illustrating Russian folk tales and inaugurated a famous series of paintings on the themes drawn from Russian folklore.
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.
The Bolshoi Theatre is a historic theatre in Moscow, Russia, which holds ballet and opera performances. The company was founded on 28 March [O.S. 17 March] 1776, when Catherine the Great granted Prince Pyotr Urusov a licence to organise theatrical performances, balls and other forms of entertainment. Usunov set up the theatre in collaboration with English tightrope walker Michael Maddox. The present building was built between 1821 and 1824 and designed by architect Joseph Bové.
Fyodor Dostoevsky (1821–81; depicted in 1872) was a Russian novelist, short story writer, essayist and philosopher. After publishing his first novel, Poor Folk, at age 25, Dostoyevsky wrote (among others) eleven novels, three novellas, and seventeen short novels, including Crime and Punishment (1866), The Idiot (1869), and The Brothers Karamazov (1880).
Chicken Kiev, also known as chicken Kyiv and chicken à la Kyiv, is a dish made of chickenfillet pounded and rolled around cold butter, then coated with egg and bread crumbs, and either fried or baked. Since fillets are often referred to as suprêmes in professional cookery, the dish is also called "suprême de volaille à la Kiev". Stuffed chicken breast is generally known in Russian and Ukrainian cuisines as côtelette de volaille. Though it has disputed origins, the dish is particularly popular in the post-Soviet states, as well as in several other countries of the former Eastern Bloc, and in the English-speaking world.
