Anti-tank dogs (Russian: собаки-истрСбитСли Ρ‚Π°Π½ΠΊΠΎΠ² sobaki-istrebiteli tankov or ΠΏΡ€ΠΎΡ‚ΠΈΠ²ΠΎΡ‚Π°Π½ΠΊΠΎΠ²Ρ‹Π΅ собаки protivotankovye sobaki; German: Panzerabwehrhunde or Hundeminen, "dog-mines") were dogs taught to carry explosives to tanks, armored vehicles and other military targets. They were intensively trained by the Soviet and Russian military forces between 1930 and 1996, and used from 1941 to 1943, against German tanks in World War II. Initially dogs were trained to leave a timer-detonated bomb and retreat, but this routine was replaced by an impact-detonation procedure which killed the dog in the process. The U.S. military started training anti-tank dogs in 1943 in the same way the Russians used them, but this training exposed several problems and the program was discontinued.

Yuri Alekseyevich Gagarinβ€Š (9 March 1934 – 27 March 1968) was a Soviet Air Forces pilot and cosmonaut who became the first human to journey into outer space, achieving a major milestone in the Space Race; his capsule Vostok 1 completed one orbit of Earth on 12 April 1961. Gagarin became an international celebrity and was awarded many medals and titles, including Hero of the Soviet Union, his nation's highest honour.

Born in the village of Klushino near Gzhatsk (a town later renamed after him), in his youth Gagarin was a foundryman at a steel plant in Lyubertsy. He later joined the Soviet Air Forces as a pilot and was stationed at the Luostari Air Base, near the Norwegian border, before his selection for the Soviet space programme with five other cosmonauts. Following his spaceflight, Gagarin became deputy training director of the Cosmonaut Training Centre, which was later named after him. He was also elected as a deputy of the Soviet of the Union in 1962 and then to the Soviet of Nationalities, respectively the lower and upper chambers of the Supreme Soviet.

Vostok 1 was Gagarin's only spaceflight but he served as the backup crew to the Soyuz 1 mission, which ended in a fatal crash, killing his friend and fellow cosmonaut Vladimir Komarov. Fearing for his life, Soviet officials permanently banned Gagarin from further spaceflights. After completing training at the Zhukovsky Air Force Engineering Academy on 17 February 1968, he was allowed to fly regular aircraft. Gagarin died five weeks later when the MiG-15 training jet he was piloting with his flight instructor Vladimir Seryogin crashed near the town of Kirzhach.

πŸ”— Sverdlovsk Anthrax Leak

πŸ”— Soviet Union πŸ”— Russia πŸ”— Environment πŸ”— Military history πŸ”— Disaster management πŸ”— Death πŸ”— Occupational Safety and Health πŸ”— Military history/Russian, Soviet and CIS military history

On 2 April 1979, spores of anthrax were accidentally released from a Soviet military research facility near the city of Sverdlovsk, Russia (now Yekaterinburg). The ensuing outbreak of the disease resulted in approximately 100 deaths, although the exact number of victims remains unknown. The cause of the outbreak was denied for years by the Soviet authorities, which blamed the deaths on consumption of tainted meat from the area, and subcutaneous exposure due to butchers handling the tainted meat. All medical records of the victims were removed to hide serious violations of the Biological Weapons Convention. The accident is sometimes referred to as "biological Chernobyl".

πŸ”— Karelian Question

πŸ”— International relations πŸ”— Soviet Union πŸ”— Russia πŸ”— Russia/politics and law of Russia πŸ”— Finland

The Karelian question or Karelian issue (Finnish: Karjala-kysymys, Swedish: Karelska frΓ₯gan) is a dispute in Finnish politics over whether to try to regain control over eastern Finnish Karelia and other territories ceded to the Soviet Union in the Winter War and the Continuation War. Despite the name "Karelian question", the term may refer also to the return of Petsamo, ceded parts of Salla and Kuusamo, and four islands in the Gulf of Finland. Sometimes the phrase "debate on the return of the ceded territories" (luovutettujen alueiden palautuskeskustelu, Swedish: debatten om tillbakalΓ€mningen av de avtrΓ€dda territorierna) is used. The Karelian question remains a matter of public debate rather than a political issue.

πŸ”— Korbut Flip

πŸ”— Soviet Union πŸ”— Russia πŸ”— History πŸ”— Russia/sports and games in Russia πŸ”— Gymnastics

The Korbut flip is a gymnastics skill performed on either of two different apparatus. Both were first performed internationally by the Soviet gymnast Olga Korbut.

The more spectacular version of the skill used to be performed on the uneven bars, where the gymnast, from a stand on the high bar, performs a back flip and regrasps the bar. Korbut performed the move at the 1972 Summer Olympics, where it was the first backward release move performed on the uneven bars in international competition. In 1977, Soviet gymnast Elena Mukhina modified the flip by adding a full twist. The movement was later modified in the 1980s when it was performed towards the low bar; that is, the gymnast's flip takes place above the low bar. The Code of Points was later modified to ban standing on the high bar during routines.

The skill is also performed on the balance beam. The move is performed from a standing position and is landed in a straddled position on the beam. This movement has been modified to include twists and piked or tucked legs and is frequently performed in sequence with other movements. Unlike its counterpart on the uneven bars, the Korbut flip on beam is today considered a relatively simple skill, valued at only a "B" level in the 2017 Code of Points.

Other gymnasts who have performed the skill's uneven bars variation include Radka Zemanova (1980), Steffi Kraker (1977), Emily May (1981), Lyubov Bogdanova (1974) and Natalia Shaposhnikova (1976).

πŸ”— Tennis racket theorem – Wikipedia

πŸ”— Russia πŸ”— Physics πŸ”— Russia/science and education in Russia

The tennis racket theorem or intermediate axis theorem is a result in classical mechanics describing the movement of a rigid body with three distinct principal moments of inertia. It is also dubbed the Dzhanibekov effect, after Russian cosmonaut Vladimir Dzhanibekov who noticed one of the theorem's logical consequences while in space in 1985 although the effect was already known for at least 150 years before that.

The theorem describes the following effect: rotation of an object around its first and third principal axes is stable, while rotation around its second principal axis (or intermediate axis) is not.

This can be demonstrated with the following experiment: hold a tennis racket at its handle, with its face being horizontal, and try to throw it in the air so that it will perform a full rotation around the horizontal axis perpendicular to the handle, and try to catch the handle. In almost all cases, during that rotation the face will also have completed a half rotation, so that the other face is now up. By contrast, it is easy to throw the racket so that it will rotate around the handle axis (the third principal axis) without accompanying half-rotation around another axis; it is also possible to make it rotate around the vertical axis perpendicular to the handle (the first principal axis) without any accompanying half-rotation.

The experiment can be performed with any object that has three different moments of inertia, for instance with a book, remote control or smartphone. The effect occurs whenever the axis of rotation differs only slightly from the object's second principal axis; air resistance or gravity are not necessary.

πŸ”— Dené–Yeniseian Languages

πŸ”— Russia πŸ”— Linguistics πŸ”— Russia/demographics and ethnography of Russia πŸ”— Languages πŸ”— Indigenous peoples of North America πŸ”— Russia/language and literature of Russia

Dené–Yeniseian is a proposed language family consisting of the Yeniseian languages of central Siberia and the Na-DenΓ© languages of northwestern North America.

Reception among experts has been largely, though not universally, favorable; thus, Dené–Yeniseian has been called "the first demonstration of a genealogical link between Old World and New World language families that meets the standards of traditional comparative-historical linguistics," besides the Eskimo–Aleut languages spoken in far eastern Siberia and North America.
