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 a 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 Caspian expeditions of the Rus' were military raids undertaken by the Rus' between the late 9th century and c. 1041 on the Caspian Sea shores, of what are nowadays Iran, Dagestan, and Azerbaijan. Initially, the Rus' appeared in Serkland in the 9th century travelling as merchants along the Volga trade route, selling furs, honey, and slaves. The first small-scale Viking raids took place in the late 9th and early 10th century. The Rus' undertook the first large-scale expedition in 913; having arrived on 500 ships, they pillaged in the Gorgan region, in the territory of present-day Iran, and more to the west, in Gilan and Mazandaran, taking slaves and goods. On their return, the northern raiders were attacked and defeated by the Khazars in the Volga Delta, and those who escaped were killed by the local tribes in the middle Volga.
During their next expedition in 943, the Rus' captured Bardha'a, the capital of Arran, in the modern-day Republic of Azerbaijan. The Rus' stayed there for several months, killing many inhabitants of the city and amassing substantial plunder. It was only an outbreak of dysentery among the Rus' that forced them to depart with their spoils. Sviatoslav, prince of Kiev, commanded the next attack, which destroyed the Khazar state in 965. Sviatoslav's campaign established the Rus's hold on the north-south trade routes, helping to alter the demographics of the region. Raids continued through the time period with the last Scandinavian attempt to reestablish the route to the Caspian Sea taking place in c. 1041 by Ingvar the Far-Travelled. (Full article...)
Peresvet and Pobeda were salvaged after the Japanese captured Port Arthur and incorporated into the Imperial Japanese Navy. Peresvet was sold back to the Russians during World War I, as the two countries were by now allies, and sank after hitting German mines in the Mediterranean in early 1917 while Pobeda, renamed Suwo, remained instead in Japanese service and participated in the Battle of Tsingtao in late 1914. She became a gunnery training ship in 1917. The ship was disarmed in 1922 to comply with the terms of the Washington Naval Treaty and probably scrapped around that time. (Full article...)
After the mutineers sought asylum in Constanța, Romania, and after the Russians recovered the ship, her name was changed to Panteleimon. She accidentally sank a Russian submarine in 1909 and was badly damaged when she ran aground in 1911. During World War I, Panteleimon participated in the Battle of Cape Sarych in late 1914. She covered several bombardments of the Bosphorus fortifications in early 1915, including one where the ship was attacked by the OttomanbattlecruiserYavuz Sultan Selim – Panteleimon and the other Russian pre-dreadnoughts present drove her off before she could inflict any serious damage. The ship was relegated to secondary roles after Russia's first dreadnought battleship entered service in late 1915. She was by then obsolete and was reduced to reserve in 1918 in Sevastopol.

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 system of public music education. 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 that 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.

Adult rainbow trout
The rainbow trout (Oncorhynchus mykiss) is a species of trout native to cold-water tributaries of the Pacific Ocean in North America and Asia. 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...)
Not much is known about Zotov's life aside from his connection to Peter. Zotov left Moscow for a diplomatic mission to Crimea in 1680 and returned to Moscow before 1683. He became part of the "Jolly Company", a group of several dozen of Peter's friends that eventually became The All-Joking, All-Drunken Synod of Fools and Jesters. Zotov was mockingly appointed "Prince-Pope" of the Synod, and regularly led them in games and celebrations. He accompanied Peter on many important occasions, such as the Azov campaigns and the torture of the Streltsy after their uprising. Zotov held a number of state posts, including from 1701 a leading position in the Tsar's personal secretariat. Three years before his death, Zotov married a woman 50 years his junior. He died in December 1717 of unknown causes. (Full article...)
In December 2016, over 70 people died of methanol poisoning in the Russian city of Irkutsk. Precipitated by the consumption of adulteratedsurrogate alcohol, it was the deadliest such incident in Russia's post-Soviet history.
Russian consumption of surrogate alcohol rose rapidly in the early 2010s amid worsening economic conditions. Surrogates cost less than government-regulated vodka and were commonly available from supermarkets, small shops, and vending machines. In the Irkutsk incident, people drank hawthorn-scented bath oil with the brand name boyaryshnik. While the product was typically made with and labeled as containing drinkable ethanol, at least one batch was made instead with a toxic amount of methanol. The resulting poisoning led to dozens of casualties and deaths among residents of the Novo-Lenino neighborhood in Irkutsk. A subsequent government investigation found that the surrogate alcohol's producer sourced the methanol from an employee of a local windshield washer fluid production facility. In response to the poisoning, in mid-2017 the Russian government increased legal punishments for illegally producing and selling alcohol and made it more difficult to acquire surrogate alcohols.

Rimsky-Korsakov believed in developing a nationalistic style of classical music, as did his fellow composer Mily Balakirev and the critic Vladimir Stasov. This style employed Russian folk song and lore along with exotic harmonic, melodic and rhythmic elements in a practice known as musical orientalism, and eschewed traditional Western compositional methods. Rimsky-Korsakov appreciated Western musical techniques after he became a professor of musical composition, harmony, and orchestration at the Saint Petersburg Conservatory in 1871. He undertook a rigorous three-year program of self-education and became a master of Western methods, incorporating them alongside the influences of Mikhail Glinka and fellow members of The Five. Rimsky-Korsakov's techniques of composition and orchestration were further enriched by his exposure to the works of Richard Wagner. (Full article...)

King Władysław II Jagiełło, detail of the Triptych of Our Lady of Sorrows in the Wawel Cathedral, Kraków
Jogaila was the last pagan ruler of medieval Lithuania. After he became King of Poland, as a result of the Union of Krewo, the newly formed Polish-Lithuanian union confronted the growing power of the Teutonic Order. The allied victory at the Battle of Grunwald in 1410, followed by the Peace of Thorn, secured the Polish and Lithuanian borders and marked the emergence of the Polish–Lithuanian alliance as a significant force in Europe. The reign of Władysław II Jagiełło extended Polish frontiers and is often considered the beginning of Poland's Golden Age. (Full article...)
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...)
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.
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).
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.
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 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.
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.
The Great Coat of Arms of the Russian Empire, as presented to Emperor Paul I in October 1800. The use of the double-headed eagle in the coat of arms (seen in multiple locations here) goes back to the 15th century. With the fall of Constantinople and the end of the Byzantine Empire in 1453, the Grand Dukes of Moscow came to see themselves as the successors of the Byzantine heritage, a notion reinforced by the marriage of Ivan III to Sophia Paleologue. Ivan adopted the golden Byzantine double-headed eagle in his seal, first documented in 1472, marking his direct claim to the Roman imperial heritage and his assertion as sovereign equal and rival to the Holy Roman Empire.
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.
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.
October 26, 2002 - Moscow theater hostage crisis: The police pumped anesthetic into the building, then stormed it from every entrance. The subsequent gunfight left 42 terrorists and 120 hostages dead.
Tula pryanik (Russian: тульский пряник, tulskiy pryanik) is a famous type of imprinted Russianpryanik from the city of Tula. Usually, Tula pryanik looks like a rectangular tile or a flat figure. Making stamped pryanik is considered an art form. The imprints could include different patterns, symbols, images of the Tula Kremlin, names, congratulations.
The cooking of the Tula pryanik starts with preparation of the dough. The dough is made from rye flour, honey, eggs, water and spices. Next the dough is cut into pieces and rolled out. Each piece is placed on a special pryanik board [ru] with a carved pattern to give the dough its intended form. The first layer of the dough is covered with a second one with a filling in between. To make the two layers stay in place the edges are pressed together. Then the cake is turned over so that the stamped image is on top and the surface is glazed with sugar syrup. The syrup covers the picture to make it more visible after baking. Historically, each carved board is used to create just one design for pryanik. A new board is made specifically for each design. In the past, pryanik boards were made by craftsmen and nowadays, new designs are created mostly by professional artists. (Full article...)
Dmitri Dmitriyevich Shostakovich[a] (25 September [O.S. 12 September] 1906 – 9 August 1975) was a Soviet-era Russian composer and pianist who became internationally known after the premiere of his First Symphony in 1926 and thereafter was regarded as a major composer.
