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 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...)
In the early days of sound cinema, among the various distinguished composers ready to try their hand at film music, Prokofiev was not an obvious choice for the commission. Based in Paris for almost a decade, he had a reputation for experimentation and dissonance, characteristics at odds with the cultural norms of the Soviet Union. By early 1933, however, Prokofiev was anxious to return to his homeland, and saw the film commission as an opportunity to write music in a more popular and accessible style. (Full article...)
Manuel I Komnenos (Greek: Μανουήλ Κομνηνός, romanized: Manouḗl Komnēnós; 28 November 1118 – 24 September 1180), Latinized as Comnenus, also called Porphyrogenitus (Greek: Πορφυρογέννητος; "born in the purple"), was a Byzantine emperor of the 12th century who reigned over a crucial turning point in the history of Byzantium and the Mediterranean. His reign saw the last flowering of the Komnenian restoration, during which the Byzantine Empire experienced a resurgence of military and economic power and enjoyed a cultural revival.
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.

Nadezhda Vasilievna Stasova (Russian: Надежда Васильевна Стасова; June 24 [O.S. June 12] 1822 – October 9 [O.S. September 27] 1895) was a Russian educator, activist, and feminist. 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".
The triumvirate founded and led several organizations designed to promote women's cultural and economic independence, including a publishing cooperative. Subsequently, the triumvirate pushed government officials to allow higher education for women, although continuing opposition meant that their successes were sometimes limited or reversed. Stasova eventually became the lead organizer of the Bestuzhev Courses in 1878, but a decade later was forced to resign under political pressure. In her final years, she continued her support for the cause of women's rights in Russia. Stasova died in 1895. (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.

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...)
The Firebird (French: L'Oiseau de feu; Russian: Жар-птица, romanized: Zhar-ptitsa) is a ballet and orchestral concert work by the Russian composer Igor Stravinsky. It was written for the 1910 Paris season of Sergei Diaghilev's Ballets Russes company; the original choreography was by Michel Fokine, who collaborated with Alexandre Benois and others on a scenario based on the Russian fairy tales of the Firebird and the blessing and curse it possesses for its owner. It was first performed at the Opéra de Paris on 25 June 1910 and was an immediate success, catapulting Stravinsky to international fame and leading to future Diaghilev–Stravinsky collaborations including Petrushka (1911) and The Rite of Spring (1913).
The Firebird's mortal and supernatural elements are distinguished with a system of leitmotifs placed in the harmony dubbed "leit-harmony". Stravinsky intentionally used many specialist techniques in the orchestra, including ponticello, col legno, flautando, glissando, and flutter-tonguing. Set in the evil immortal Koschei's castle, the ballet follows Prince Ivan, who battles Koschei with the help of the magical Firebird. (Full article...)

In mid- to late-19th-century Russia, Pyotr Ilyich Tchaikovsky and a group of composers known as The Five had differing opinions as to whether Russian classical music should be composed following Western or native practices. Tchaikovsky wanted to write professional compositions of such quality that they would stand up to Western scrutiny and thus transcend national barriers, yet remain distinctively Russian in melody, rhythm and other compositional characteristics. The Five, made up of composers Mily Balakirev, Alexander Borodin, César Cui, Modest Mussorgsky, and Nikolai Rimsky-Korsakov, sought to produce a specifically Russian kind of art music, rather than one that imitated older European music or relied on European-style conservatory training. While Tchaikovsky himself used folk songs in some of his works, for the most part he tried to follow Western practices of composition, especially in terms of tonality and tonal progression. Also, unlike Tchaikovsky, none of The Five were academically trained in composition; in fact, their leader, Balakirev, considered academicism a threat to musical imagination. Along with critic Vladimir Stasov, who supported The Five, Balakirev attacked relentlessly both the Saint Petersburg Conservatory, from which Tchaikovsky had graduated, and its founder Anton Rubinstein, orally and in print.
As Tchaikovsky had become Rubinstein's best-known student, he was initially considered by association as a natural target for attack, especially as fodder for Cui's printed critical reviews. This attitude changed slightly when Rubinstein left the Saint Petersburg musical scene in 1867. In 1869 Tchaikovsky entered into a working relationship with Balakirev; the result was Tchaikovsky's first recognized masterpiece, the fantasy-overture Romeo and Juliet, a work which The Five wholeheartedly embraced. When Tchaikovsky wrote a positive review of Rimsky-Korsakov's Fantasy on Serbian Themes he was welcomed into the circle, despite concerns about the academic nature of his musical background. The finale of his Second Symphony, nicknamed the Little Russian, was also received enthusiastically by the group on its first performance in 1872. (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...)

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 as of 2024[update].
Oganesson has the highest atomic number and highest atomic mass of all known elements as of 2024[update]. 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, as of 2020,[update] 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).

Maria Vasilievna Trubnikova (Russian: Мари́я Васи́льевна Тру́бникова, néeIvasheva [Ивашева]; 6 January 1835 – 28 April 1897) was a Russian feminist and activist. Of mixed Russian and French heritage, Trubnikova was orphaned at an early age and subsequently raised by a wealthy relative. She married at 19; she and her husband, Konstantin, had seven children. In adulthood, Trubnikova hosted a women-only salon which became a center of feminist activism. She also maintained international connections to fellow feminists in England, France, and other countries. Alongside Anna Filosofova and Nadezhda Stasova, whom she mentored, Trubnikova 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 organizations designed to promote women's cultural and economic independence, including a publishing cooperative. Subsequently, they successfully pushed government officials to allow higher education for women, although continuing opposition meant that their successes were sometimes limited or reversed. In later life, Trubnikova experienced severe illness and personal difficulties; she died in 1897. (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...)

Ossetian, Russian, and Abkhazian forces ejected the Georgian forces after five days of heavy fighting. All parties reached a ceasefire agreement on August 12, and Russian troops remain stationed in Abkhazia and South Ossetia to this day.
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 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.
A Boyar Wedding Feast is an oil-on-canvas painting created by Russian artist Konstantin Makovsky in 1883. The boyars were members of the highest rank of the feudal aristocracy of Russia in the 16th and 17th centuries, and a wedding was an important social event. In this painting, the guests are depicted toasting a newlywed couple. They stand at the head of the table, where the groom sees his bride without her veil for the first time; she appears timid and bashful as the men toast for the first kiss. Behind the couple, the Lady of Ceremony gently urges on the bride. A roasted swan is being brought in on a large platter, the last dish to be served before the couple retires to the bedroom. The work is in the collection of the Hillwood Estate, Museum & Gardens, in Washington, D.C.
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.
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 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.
Ivan Goremykin (1839–1917) was a Russian prime minister during World War I. A politician with archconservative views, after some time in the Ministry of Justice, he transferred to the Ministry of the Interior in 1891. He held the rank of prime minister from May to July 1906 and again from 1914 to 1916; during both terms his effectiveness was strongly limited by opposition from the State Duma. In the aftermath of the October Revolution, Goremykin was recognized as a member of the Tsarist government and killed by a street mob.
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.
