Antarctica (/ænˈtɑːrktɪkə/ⓘ) is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic Ocean), it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of 14,200,000 km2 (5,500,000 sq mi). Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of 1.9 km (1.2 mi).
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Diamond as a form of carbon is tasteless, odourless, strong, brittle solid, colourless in pure form, a poor conductor of electricity, and insoluble in water. Another solid form of carbon known as graphite is the chemically stable form of carbon at room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth.
Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of defects or impurities (about one per million of lattice atoms) can color a diamond blue (boron), yellow (nitrogen), brown (defects), green (radiation exposure), purple, pink, orange, or red. Diamond also has a very high refractive index and a relatively high optical dispersion. (Full article...)
The Rite of Spring (French: Le Sacre du printemps) is a ballet and orchestral concert work by the Russian composer Igor Stravinsky. It was written for the 1913 Paris season of Sergei Diaghilev's Ballets Russes company; the original choreography was by Vaslav Nijinsky with stage designs and costumes by Nicholas Roerich. When first performed at the Théâtre des Champs-Élysées on 29 May 1913, the avant-garde nature of the music and choreography caused a sensation. Many have called the first-night reaction a "riot" or "near-riot", though this wording did not come about until reviews of later performances in 1924, over a decade later. Although designed as a work for the stage, with specific passages accompanying characters and action, the music achieved equal if not greater recognition as a concert piece and is widely considered to be one of the most influential musical works of the 20th century.
Stravinsky was a young, virtually unknown composer when Diaghilev recruited him to create works for the Ballets Russes. Le Sacre du printemps was the third such major project, after the acclaimed Firebird (1910) and Petrushka (1911). The concept behind The Rite of Spring, developed by Roerich from Stravinsky's outline idea, is suggested by its subtitle, "Pictures of Pagan Russia in Two Parts"; the scenario depicts various primitive rituals celebrating the advent of spring, after which a young girl is chosen as a sacrificial victim and dances herself to death. After a mixed critical reception for its original run and a short London tour, the ballet was not performed again until the 1920s, when a version choreographed by Léonide Massine replaced Nijinsky's original, which saw only eight performances. Massine's was the forerunner of many innovative productions directed by the world's leading choreographers, gaining the work worldwide acceptance. In the 1980s, Nijinsky's original choreography, long believed lost, was reconstructed by the Joffrey Ballet in Los Angeles. (Full article...)

Fram leaves Bergen on 2 July 1893, bound for the Arctic Ocean Nansen's Fram expedition of 1893–1896 was an attempt by the Norwegian explorer Fridtjof Nansen to reach the geographical North Pole by harnessing the natural east–west current of the Arctic Ocean. In the face of much discouragement from other polar explorers, Nansen took his ship Fram to the New Siberian Islands in the eastern Arctic Ocean, froze her into the pack ice, and waited for the drift to carry her towards the pole. Impatient with the slow speed and erratic character of the drift, after 18 months Nansen and a chosen companion, Hjalmar Johansen, left the ship with a team of Samoyed dogs and sledges and made for the pole. They did not reach it, but they achieved a record Farthest North latitude of 86°13.6′N before a long retreat over ice and water to reach safety in Franz Josef Land. Meanwhile, Fram continued to drift westward, finally emerging in the North Atlantic Ocean.
The idea for the expedition had arisen after items from the American vessel Jeannette, which had sunk off the north coast of Siberia in 1881, were discovered three years later off the south-west coast of Greenland. The wreckage had obviously been carried across the polar ocean, perhaps across the pole itself. Based on this and other debris recovered from the Greenland coast, the meteorologist Henrik Mohn developed a theory of transpolar drift, which led Nansen to believe that a specially designed ship could be frozen in the pack ice and follow the same track as Jeannette wreckage, thus reaching the vicinity of the pole.

The Borodino-class battlecruisers (Russian: Линейные крейсера типа «Измаил») were a group of four battlecruisers ordered by the Imperial Russian Navy before World War I. Also referred to as the Izmail class, they were laid down in late 1912 at Saint Petersburg for service with the Baltic Fleet. Construction of the ships was delayed by a lack of capacity among domestic factories and the need to order some components from abroad. The start of World War I slowed their construction still further, as the imported components were often not delivered and domestic production was diverted into areas more immediately useful for the war effort.
Three of the four ships were launched in 1915 and the fourth in 1916. Work on the gun turrets lagged, and it became evident that Russian industry would not be able to complete the ships during the war. The Russian Revolution of 1917 halted all work on the ships, which was never resumed. Although some consideration was given to finishing the hulls that were nearest to completion, the three furthest from completion were sold for scrap by the Soviet Union during the early 1920s. The Soviet Navy proposed to convert Izmail, the ship closest to completion, to an aircraft carrier in 1925, but the plan was cancelled after political manoeuvring by the Red Army cut funding and she was eventually scrapped in 1931.

Olga was raised at the Gatchina Palace outside Saint Petersburg. Olga's relationship with her mother, Empress Marie, the daughter of King Christian IX of Denmark, was strained and distant from childhood. In contrast, she and her father were close. He died when she was 12, and her brother Nicholas became emperor. In 1901, at 19, she married Duke Peter Alexandrovich of Oldenburg, who was privately believed by family and friends to be homosexual. Their marriage of 15 years remained unconsummated, and Peter at first refused Olga's request for a divorce. The couple led separate lives and their marriage was eventually annulled by the Emperor in October 1916. The following month Olga married cavalry officer Nikolai Kulikovsky, with whom she had fallen in love several years before. During the First World War, Olga served as an army nurse and was awarded a medal for personal gallantry. At the downfall of the Romanovs in the Russian Revolution of 1917, she fled with her husband and children to Crimea, where they lived under the threat of assassination. Her brother Nicholas and his family were shot and bayoneted to death by revolutionaries. (Full article...)
Tsereteli was born and raised in Georgia when it was part of the Russian Empire. A member of the Menshevik faction of the RSDLP, Tsereteli was elected to the Duma in 1907, where he gained fame for his oratorical skill. Shortly after entering the Duma, Tsereteli was arrested and charged with conspiracy to overthrow the Tsarist government, and exiled to Siberia. A dedicated Social Democrat who believed in the Menshevik ideology, Tsereteli was one of the leading figures of the movement in Russia. In 1915, during his Siberian exile, Tsereteli formed what would become known as Siberian Zimmerwaldism, which advocated for the role of the Second International in ending the war. He also developed the idea of "Revolutionary Defensism", the concept of a defensive war which only allowed for the defence of territory, and argued it was not being utilized. (Full article...)

Jeannette at Le Havre in 1878, prior to her departure for San Francisco in a trip that would see her round Cape Horn The Jeannetteexpedition of 1879–1881, officially called the U.S. Arctic Expedition, was an attempt led by George W. De Long to reach the North Pole by pioneering a route from the Pacific Ocean through the Bering Strait. The premise was that a temperate current, the Kuro Siwo, flowed northwards into the strait, providing a gateway to the hypothesized Open Polar Sea and thus to the pole.
This theory proved illusory; the expedition's ship, USS Jeannette and its crew of thirty-three men, was trapped by ice and drifted for nearly two years before she was crushed and sunk north of the Siberian coast. De Long then led his men on a perilous journey by sled, dragging the Jeannette'swhaleboat and two cutters, eventually switching to these small boats to sail for the Lena Delta in Siberia. During this journey, and in the subsequent weeks of wandering in Siberia before rescue, twenty of the ship's complement died, including De Long. (Full article...)
Viatkogorgon is a genus of gorgonopsian (a type of therapsid, the group that includes modern mammals) that lived during the Permian period in what is now Russia. The first fossil was found at the Kotelnich locality near the Vyatka River and was made the holotype of the new genus and speciesV. ivachnenkoi in 1999. The generic name refers to the river and the related genus Gorgonops—the gorgons of Greek mythology are often referenced in the names of the group. The specific name honors the paleontologist Mikhail F. Ivakhnenko. The holotype skeleton is one of the most complete gorgonopsian specimens known and includes rarely preserved elements such as gastralia (abdominal ribs) and a sclerotic ring (a bony ring inside the eye). A larger, but poorly preserved specimen has also been assigned to the species.
The holotype specimen is about 80 cm (31 in) long, including the 14 cm (5.5 in) long skull, making Viatkogorgon a relatively small gorgonopsian. The assigned specimen is larger, with a 17 cm (6.7 in) long skull, and the holotype may have been young. As a gorgonopsian, it would have been skeletally robust with a somewhat dog-like stance, though with outwards-turned elbows. The snout was high, and the teeth were generally recurved (curved backward), pointed, and serrated. The canines (the saber teeth) were much larger than the incisors at the front and postcanines behind but relatively small for a gorgonopsian. Viatkogorgon was characterized by its unusually large eye socket and sclerotic ring. It was distinct from other gorgonopsians in that the lower end of the postorbital bar was narrow, and it had a very large sulcus (or furrow) at the back of the skull on each side. Since gorgonopsians have been described mainly from skulls, it is uncertain how widespread the postcranial features of Viatkogorgon were in other members of the group. The skeleton of Viatkogorgon was unusual in having gastralia, in that the tail was differentiated with a front and hind part, with the former less flexible, and in that some of the foot bones and its digits were reduced in size and interconnected.

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...)

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.

The Gurian Republic was an insurgent community that existed between 1902 and 1906 in the western Georgian region of Guria (known at the time as the Ozurget Uyezd) in the Russian Empire. It rose from a revolt over land grazing rights in 1902. Several issues over the previous decades affecting the peasant population including taxation, land ownership and economic factors also factored into the start of the insurrection. The revolt gained further traction through the efforts of Georgian social democrats, despite some reservations within their party over supporting a peasant movement, and grew further during the 1905 Russian Revolution.
During its existence, the Gurian Republic ignored Russian authority and established its own system of government, which consisted of assemblies of villagers meeting and discussing issues. A unique form of justice, where trial attendees voted on sentences, was introduced. While the movement broke from imperial administration, it was not anti-Russian, desiring to remain within the Empire. (Full article...)

The official arrangement of the Russian national anthem, completed in 2001
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...)
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.
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.
The Solovetsky Monastery is a Russian Orthodox monastery in Solovetsky, Arkhangelsk, Russia. Founded in 1436 by the monk Zosima, the monastery grew in power into the 16th century, becoming an economic and political center of the White Sea region and eventually hosting 350 monks. After the Bolshevik Revolution, Soviet authorities closed down the monastery and incorporated many of its buildings into Solovki prison camp, one of the earliest forced-labor camps of the gulag system. The camp closed after the region's trees had been harvested. Today the monastery has been re-established, and also serves as a museum.
Charles Minard's Carte figurative (1869), which details the losses of men, the position of the army, and the freezing temperatures on Napoleon's disastrous 1812 invasion of Russia. Created in an effort to show the horrors of war, the graph "defies the pen of the historian in its brutal eloquence" and has been called the best statistical graphic ever drawn.
Saint Basil's Cathedral is a church in Red Square in Moscow, Russia. It was built from 1555 to 1561 on orders from Ivan the Terrible and commemorates the capture of Kazan and Astrakhan. The city's tallest building until the completion of the Ivan the Great Bell Tower in 1600, the original building contained eight side churches arranged around the ninth, central church of Intercession; the tenth church was erected in 1588 over the grave of venerated local saint Vasily (Basil). Although the Bolsheviks considered demolishing the church in the 1930s, it was spared. Since 1991 it has housed a branch of the State Historical Museum and hosted occasional church services.
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.
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.
Sadko is a character in the Russian medieval epic Bylina. An adventurer, merchant and gusli musician from Novgorod, Sadko becomes wealthy with the help of the Sea Tsar, but is thrown in the sea when he fails to pay the Sea Tsar his due respects. This story was widely adapted in the 19th century, including in a poem by Alexei Tolstoy and an opera by Nikolai Rimsky-Korsakov.
Shown here is Sadko in the Underwater Kingdom, an 1876 painting by Ilya Repin. It depicts Sadko meeting the Sea Tsar under the sea.
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.
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.

Its recipe was developed by the Russian Academy of Agricultural Sciences in the Scientific Research Institute of Food Biotechnology. (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.

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.
