A natural diamond crystal
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...)

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 Shuttle–Mir program (Russian: Программа «Мир»–«Шаттл») was a collaborative space program between Russia and the United States that involved American Space Shuttles visiting the Russian space stationMir, Russian cosmonauts flying on the Shuttle, and an American astronaut flying aboard a Soyuz spacecraft to allow American astronauts to engage in long-duration expeditions aboard Mir.
The project, sometimes called "Phase One", was intended to allow the United States to learn from Russian experience with long-duration spaceflight and to foster a spirit of cooperation between the two nations and their space agencies, the National Aeronautics and Space Administration (NASA) and the Russian Space Agency (PKA). The project helped to prepare the way for further cooperative space ventures; specifically, "Phase Two" of the joint project, the construction of the International Space Station (ISS). The program was announced in 1993, the first mission started in 1994 and the project continued until its scheduled completion in 1998. Eleven Space Shuttle missions, a joint Soyuz flight and almost 1,000 cumulative days in space for American astronauts occurred over the course of seven long-duration expeditions. In addition to Space Shuttle launches to Mir the United States also fully funded and equipped with scientific equipment the Spektr module (launched in 1995) and the Priroda module (launched in 1996), making them de facto U.S. modules during the duration of the Shuttle-Mir program.

Extent of Ali Bey and Zahir's territory between 1768 and 1774 and Russian naval movements in the Levant, based on the accounts of Sauveur Lusignan, a contemporary historian Beirut was twice occupied during the Russo-Turkish War of 1768–1774 by squadrons of the Imperial Russian Navy's Mediterranean Fleet, first in June 1772 and second from October 1773 to early 1774, as part of its Levant campaign. Russia's main objective in this campaign was to assist local forces led by Egypt's autonomous ruler, Ali Bey al-Kabir, who was in open rebellion against the Ottoman Empire.
Russia, led by Catherine the Great, was pressing the Ottomans in Europe. Ali took advantage of the Empire's preoccupation with Russia to declare Egypt's independence; in 1771 he sent an army led by Muhammad Bey Abu al-Dhahab to occupy Ottoman territory in the Levant. Abu al-Dhahab unexpectedly returned to challenge Ali for control of Egypt. Ali requested Russian military assistance against both his rival and the Ottomans. When this aid, in the form of a small Russian squadron, arrived in the region, Ali had already fled Egypt and taken refuge in Acre, the power base of his ally, Zahir al-Umar. After helping repel an Ottoman offensive on Sidon, the Russian squadron sailed for Beirut. They bombarded the town in June 1772 and occupied it from June23 to 28. (Full article...)
The Norslunda Runestone, bearing runic inscription U 419, which mentions the personal name Kylfingr The Kylfings (Old NorseKylfingar; EstonianKalevid; HungarianKölpények; Old East Slavic Колбяги, Kolbiagi; Byzantine Greek Κουλπίγγοι, Koulpingoi; Arabical-Kilabiyya) were a people of uncertain origin active in Northern Europe during the Viking Age, roughly from the late ninth century to the early twelfth century. They could be found in areas of Lapland, Russia, and the Byzantine Empire that were frequented by Scandinavian traders, raiders and mercenaries. Scholars differ on whether the Kylfings were ethnically Finnic or Norse. Also disputed is their geographic origin, with Denmark, Sweden and the Eastern Baltic all put forward as candidates. Whether the name Kylfing denotes a particular tribal, socio-political, or economic grouping is also a matter of much debate.
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...)

A bowl of borscht garnished with sour cream and dill
Borscht (English: /ˈbɔːrʃt/ⓘ) is a sour soup, made with meat stock, vegetables and seasonings, common in Eastern Europe and Northern Asia. In English, the word borscht is most often associated with the soup's variant of Ukrainian origin, made with red beetroots as one of the main ingredients, which give the dish its distinctive red color. The same name, however, is also used for a wide selection of sour-tasting soups without beetroots, such as sorrel-based green borscht, rye-based white borscht, and cabbage borscht.
Borscht derives from an ancient soup originally cooked from pickled stems, leaves and umbels of common hogweed (Heracleum sphondylium), an herbaceous plant growing in damp meadows, which lent the dish its Slavic name. With time, it evolved into a diverse array of tart soups, among which the Ukrainian beet-based red borscht has become the most popular. It is typically made by combining meat or bone stock with sautéed vegetables, which—as well as beetroots—usually include cabbage, carrots, onions, potatoes, and tomatoes. Depending on the recipe, borscht may include meat or fish, or be purely vegetarian; it may be served either hot or cold, and it may range from a hearty one-pot meal to a clear broth or a smooth drink. It is often served with smetana or sour cream, hard-boiled eggs or potatoes, but there exists an ample choice of more involved garnishes and side dishes, such as uszka or pampushky, that can be served with the soup.

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...)
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...)

Tennessine is a synthetic chemical element; it has symbolTs and atomic number 117. It has the second-highest atomic number and joint-highest atomic mass of all known elements and is the penultimate element of the 7th period of the periodic table. It is named after the U.S. state of Tennessee, where key research institutions involved in its discovery are located (however, the IUPAC says that the element is named after the "region of Tennessee").
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, a name which was officially adopted in November 2016. (Full article...)
Nadezhda Vasilievna Stasova (Russian: Надежда Васильевна Стасова; June 24 [O.S. June 12] 1822 – October 9 [O.S. September 27] 1895) was a prominent Russian educator, activist, and feminist of the 19th century.
Stasova was born into a noble and wealthy family; Tsar Alexander I of Russia was her godfather, and she received extensive private tutoring as a child. After experiencing family tragedy and personal disappointment as a young woman, she dedicated herself to women's education and economic empowerment. Alongside Anna Filosofova and Maria Trubnikova, Stasova was one of the earliest leaders of the Russian women's movement. Together, the three friends and allies were referred to as the "triumvirate".

With the pale yellow rump visible. Buryatia, Russia.
Pallas's leaf warbler is one of the smallest Palearcticwarblers, with a relatively large head and short tail. It has greenish upperparts and white underparts, a lemon-yellow rump, and yellow double wingbars, supercilia and central crown stripe. It is similar in appearance to several other Asian warblers, including some that were formerly considered to be subspecies of it, although its distinctive vocalisations aid identification.

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 lives 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.

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.
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.
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.
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.
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.
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.
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.
The current main building of the Moscow State University in Sparrow Hills, Moscow, Russia. Designed by Lev Rudnev and completed by 1953, the 240-metre (790 ft) tall structure was the tallest building in Europe until the completion of the Messeturm in 1990.

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.
