Oganesson is a synthetic chemical element; it has symbolOg and atomic number 118. It was first synthesized in 2002 at the Joint Institute for Nuclear Research (JINR) in Dubna, near Moscow, Russia, by a joint team of Russian and American scientists. In December 2015, it was recognized as one of four new elements by the Joint Working Party of the international scientific bodies IUPAC and IUPAP. It was formally named on 28 November 2016. The name honors the nuclear physicist Yuri Oganessian, who played a leading role in the discovery of the heaviest elements in the periodic table. It is one of only two elements named after a person who was alive at the time of naming, the other being seaborgium, and the only element whose eponym is alive .
Oganesson has the highest atomic number and highest atomic mass of all known elements . On the periodic table of the elements it is a p-block element, a member of group 18 and the last member of period 7. Its only known isotope, oganesson-294, is highly radioactive, with a half-life of 0.7 ms and, only five atoms have been successfully produced. This has so far prevented any experimental studies of its chemistry. Because of relativistic effects, theoretical studies predict that it would be a solid at room temperature, and significantly reactive, unlike the other members of group 18 (the noble gases).

The black stork (Ciconia nigra) is a large bird in the stork family Ciconiidae. It was first described by Carl Linnaeus in the 10th edition of his Systema Naturae. Measuring on average 95 to 100 cm (37 to 39 in) from beak tip to end of tail with a 145-to-155 cm (57-to-61 in) wingspan, the adult black stork has mainly black plumage, with white underparts, long red legs and a long pointed red beak. A widespread but uncommon species, it breeds in scattered locations across Europe (predominantly in Portugal and Spain, and central and eastern parts), and east across the Palearctic to the Pacific Ocean. It is a long-distance migrant, with European populations wintering in tropical Sub-Saharan Africa, and Asian populations in the Indian subcontinent. When migrating between Europe and Africa, it avoids crossing broad expanses of the Mediterranean Sea and detours via the Levant in the east, the Strait of Sicily in the center, or the Strait of Gibraltar in the west. An isolated, non-migratory, population occurs in Southern Africa.
Unlike the closely related white stork, the black stork is a shy and wary species. It is seen singly or in pairs, usually in marshy areas, rivers or inland waters. It feeds on amphibians, small fish and insects, generally wading slowly in shallow water stalking its prey. Breeding pairs usually build nests in large forest trees—most commonly deciduous but also coniferous—which can be seen from long distances, as well as on large boulders, or under overhanging ledges in mountainous areas. The female lays two to five greyish-white eggs, which become soiled over time in the nest. Incubation takes 32 to 38 days, with both sexes sharing duties, and fledging takes 60 to 71 days.

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.

Nihonium was first reported to have been created in 2003 by a Russian–American collaboration at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, and in 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...)
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...)
The rainbow trout (Oncorhynchus mykiss) is a species of trout native to cold-water tributaries of the Pacific Ocean in Asia and North America. The steelhead (sometimes called steelhead trout) is an anadromous (sea-run) form of the coastal rainbow trout(O. m. irideus) or Columbia River redband trout(O. m. gairdneri) that usually returns to freshwater to spawn after living two to three years in the ocean. Freshwater forms that have been introduced into the Great Lakes and migrate into tributaries to spawn are also called steelhead.
Adult freshwater stream rainbow trout average between 0.5 and 2.5 kilograms (1 and 5 lb), while lake-dwelling and anadromous forms may reach 9 kg (20 lb). Coloration varies widely based on subspecies, forms, and habitat. Adult fish are distinguished by a broad reddish stripe along the lateral line, from gills to the tail, which is most vivid in breeding males. (Full article...)
The discovery of tennessine was officially announced in Dubna, Russia, by a Russian–American collaboration in April 2010, which makes it the most recently discovered element . One of its daughter isotopes was created directly in 2011, partially confirming the results of the experiment. The experiment itself was repeated successfully by the same collaboration in 2012 and by a joint German–American team in May 2014. In December 2015, the Joint Working Party of the International Union of Pure and Applied Chemistry (IUPAC) and the International Union of Pure and Applied Physics (IUPAP), which evaluates claims of discovery of new elements, recognized the element and assigned the priority to the Russian–American team. In June 2016, the IUPAC published a declaration stating that the discoverers had suggested the name tennessine after Tennessee, United States, a name which was officially adopted in November 2016.

The ship was torpedoed during the Japanese surprise attack on Port Arthur during the night of 8/9 February 1904 and grounded in the harbour entrance when she attempted to take refuge inside, as her draft had significantly deepened from the amount of water she had taken aboard after the torpedo hit. She was refloated and repaired in time to join the rest of the 1st Pacific Squadron when they attempted to reach Vladivostok through the Japanese blockade on 10 August. The Japanese battle fleet engaged them again in the Battle of the Yellow Sea, forcing most of the Russian ships to return to Port Arthur after their squadron commander was killed and his flagship damaged. Retvizan was sunk by Japanese howitzers in December after the Japanese gained control of the heights around the harbour. (Full article...)
The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed. The polar bear is the largest extant species of bear and land carnivore, with adult males weighing 300–800 kg (660–1,760 lb). The species is sexually dimorphic, as adult females are much smaller. The polar bear is white- or yellowish-furred with black skin and a thick layer of fat. It is more slender than the brown bear, with a narrower skull, longer neck and lower shoulder hump. Its teeth are sharper and more adapted to cutting meat. The paws are large and allow the bear to walk on ice and paddle in the water.
Polar bears are both terrestrial and pagophilic (ice-living) and are considered to be marine mammals due to their dependence on marine ecosystems. They prefer the annual sea ice but live on land when the ice melts in the summer. They are mostly carnivorous and specialized for preying on seals, particularly ringed seals. Such prey is typically taken by ambush; the bear may stalk its prey on the ice or in the water, but also will stay at a breathing hole or ice edge to wait for prey to swim by. The bear primarily feeds on the seal's energy-rich blubber. Other prey include walruses, beluga whales and some terrestrial animals. Polar bears are usually solitary but can be found in groups when on land. During the breeding season, male bears guard females and defend them from rivals. Mothers give birth to cubs in maternity dens during the winter. Young stay with their mother for up to two and a half years. (Full article...)
A Finnish Maxim M/09-21 machine gun crew during the Winter War
The Winter War was a war between the Soviet Union and Finland. It began with a Soviet invasion of Finland on 30 November 1939, three months after the outbreak of World War II, and ended three and a half months later with the Moscow Peace Treaty on 13 March 1940. Despite superior military strength, especially in tanks and aircraft, the Soviet Union suffered severe losses and initially made little headway. The League of Nations deemed the attack illegal and expelled the Soviet Union from its organization.
The Soviets made several demands, including that Finland cede substantial border territories in exchange for land elsewhere, claiming security reasons – primarily the protection of Leningrad, 32 km (20 mi) from the Finnish border. When Finland refused, the Soviets invaded. Most sources conclude that the Soviet Union had intended to conquer all of Finland, and cite the establishment of the puppet Finnish Communist government and the Molotov–Ribbentrop Pact's secret protocols as evidence of this, while other sources argue against the idea of a full Soviet conquest. Finland repelled Soviet attacks for more than two months and inflicted substantial losses on the invaders in temperatures as low as −43 °C (−45 °F). The battles focused mainly on Taipale along the Karelian Isthmus, on Kollaa in Ladoga Karelia and on Raate Road in Kainuu, but there were also battles in Salla and Petsamo in Lapland.

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 7 November 1932. (Full article...)
Serving in the Baltic Sea during World War I, Slava was the largest ship of the Russian Gulf of Riga Squadron that fought the German High Seas Fleet in the Battle of the Gulf of Riga in August 1915. She repeatedly bombarded German positions and troops for the rest of 1915 and during 1916. During the Battle of Moon Sound in 1917, Slava was badly damaged by the German dreadnoughtSMS König, significantly increasing her draft. The shallow channel made it impossible to escape and she was scuttled in the Moon Sound Strait between the island of Muhu (Moon) and the mainland. The Estoniansscrapped her during the 1930s.

Kombat (Russian for 'battalion commander') is a black-and-white photograph by Soviet photographer Max Alpert. It depicts a Soviet military officer, armed with a TT pistol, raising his unit for an attack during World War II. This work is regarded as one of the most iconic Soviet World War II photographs, yet neither the date nor the subject is known with certainty. According to the most widely accepted version, it depicts junior politruk Aleksei Gordeyevich Yeryomenko, minutes before his death on 12 July 1942, in Voroshilovgrad Oblast, now part of Ukraine. The photograph is in the archives of RIA Novosti, a Russian state-owned news agency.
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.
Maxim Gorky (1868–1936) was a Russian political activist and writer who helped establish the Socialist Realism literary method. This portrait dates from a trip Gorky made to the United States in 1906, on which he raised funds for the Bolsheviks. During this trip he wrote his novel The Mother.
A female Siberian tiger (Panthera tigris altaica), a subspecies of tiger native to Central Asia, and her cub. The Siberian tiger is the largest of the extant tiger subspecies as well as the largest felid, attaining 320 kg (710 lb) in an exceptional specimen. Considered an endangered subspecies, the wild population is down to several hundred individuals and is limited to eastern Siberia.
Gorky Park is a park in central Moscow, Russia, inaugurated in 1928 following the use of the site in 1923 for the First All-Russian Agricultural and Handicraft Industries Exhibition. The park was named after the writer and political activist Maxim Gorky. It underwent a major reconstruction in 2011; nearly all the amusement rides and other attractions were removed, extensive lawns and flower beds were created, and new roadways were laid. A 15,000 m2 (160,000 sq ft) ice rink was installed at the same time. This picture shows the colonnaded main portal of Gorky Park.
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.
Hotel Astoria is a five-star hotel located on Saint Isaac's Square in Saint Petersburg. Commissioned in 1910 by the Palace Hotel Company to host visitors to the Romanov tercentenary, the hotel was designed by Fyodor Lidval and first opened in 1912. After the October Revolution, it continued to be used as a state-operated hotel, though during World War II it was also a field hospital. The hotel, now owned by Rocco Forte Hotels, has been renovated several times, most recently in 2012.
The Last Day of Pompeii is an oil painting on canvas completed by the Russian artist Karl Bryullov between 1830 and 1833. The painting is based on sketches the artist completed in 1828 while visiting Pompeii, a city destroyed by the eruption of Mount Vesuvius in 79 AD. It is now held in the State Russian Museum.
The Krestovsky Stadium is the home ground of FC Zenit Saint Petersburg. Photographed here in 2016, when construction was nearing completion, it is situated on Krestovsky Island in the Russian city of Saint Petersburg. It was opened in 2017 as a venue for the 2017 FIFA Confederations Cup, and hosted the final, in which Germany beat Chile 1–0. It was one of the venues for the 2018 FIFA World Cup the following year. Among other features, it has a retractable roof, and is equipped with a video-surveillance and identification system, as well as security-alarm, fire-alarm and robotic fire-extinguishing systems. The stadium's seating capacity is 67,800.
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.
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.
Saint Michael's Castle is a former royal residence in the historic centre of Saint Petersburg, Russia. It was built for Emperor Paul I between 1797 and 1801, and named after Saint Michael, the patron saint of the royal family. Constructed like a castle around a small octagonal courtyard, the four facades were built in different architectural styles, including French Classicism, Italian Renaissance and Gothic. The emperor was assassinated in the castle forty days after taking up residence. After his death, the imperial family returned to the Winter Palace and the building was transferred to the Russian Army's Main Engineering School. In 1990, it became a branch of the Russian Museum, and now houses its portrait gallery.
In the early part of the 20th century, Auguste Escoffier, the famed French chef, brought it to France and included recipes for it in his masterwork The Complete Guide to the Art of Modern Cookery. (Full article...)
