🔗 Soviet Union 🔗 Russia 🔗 Socialism 🔗 Russia/history of Russia

"On the Cult of Personality and Its Consequences" (Russian: «О культе личности и его последствиях», romanized: “O kul'te lichnosti i yego posledstviyakh”) was a report by Soviet leader Nikita Khrushchev, First Secretary of the Communist Party of the Soviet Union, made to the 20th Congress of the Communist Party of the Soviet Union on 25 February 1956. Popularly known as the Secret Speech (Russian: секретный доклад Хрущёва, romanized: sekretnïy doklad Khrushcheva), this is something of a misnomer, as copies of the speech were read out at thousands of meetings of Communist Party and Komsomol organisations across the country. Khrushchev's speech was sharply critical of the rule of the deceased General Secretary and Premier Joseph Stalin, particularly with respect to the purges which had especially marked the last years of the 1930s. Khrushchev charged Stalin with having fostered a leadership cult of personality despite ostensibly maintaining support for the ideals of communism.

The speech was shocking in its day. There are reports that some of those present suffered heart attacks and that the speech even inspired suicides, due to the shock of all of Khrushchev's criticisms and condemnations of the government and the figure of Stalin. The ensuing confusion among many Soviet citizens, raised on panegyrics and permanent praise of the "genius" of Stalin, was especially apparent in Georgia, Stalin's homeland, where days of protests and rioting ended with a Soviet army crackdown on 9 March 1956. The speech was leaked to the West by the Israeli intelligence agency Mossad, which received it from the Polish-Jewish journalist Wiktor Grajewski. It politically devastated organised communists in the West; the Communist Party USA alone lost more than 30,000 members within weeks of its publication.

The speech helped give rise to the period of liberalisation known as the Khrushchev Thaw, and the process of de-Stalinization. It was cited as a major cause of the Sino-Soviet split by China (under Chairman Mao Zedong) and Albania (under First Secretary Enver Hoxha), who condemned Khrushchev as a revisionist. In response, they formed the anti-revisionist movement, criticizing the post-Stalin leadership of the Communist Party of the Soviet Union for allegedly deviating from the path of Lenin and Stalin. In North Korea, factions of the Workers' Party of Korea attempted to remove Chairman Kim Il Sung, criticizing him for not "correcting" his leadership methods, developing a personality cult, distorting the "Leninist principle of collective leadership" and "distortions of socialist legality" (i.e. using arbitrary arrest and executions) and using other Khrushchev-era criticisms of Stalinism against Kim Il Sung's leadership.

The Pip is the nickname given by radio listeners to a shortwave radio station that broadcasts on the frequency 5448 kHz by day, and 3756 kHz during the night. It broadcasts short, repeated beeps at a rate of around 50 per minute, for 24 hours per day. The beep signal is occasionally interrupted by voice messages in Russian. The Pip has been active since around 1985, when its distinctive beeping sound was first recorded by listeners.

The station is commonly referred to as "The Pip" among English-speaking radio listeners. In Russia, it is known as Капля (Kaplya) "the drop". While its official name or callsign is not known, some of the voice transmissions begin with the code 8S1Shch (Cyrillic: 8С1Щ), which is generally considered to be the name of the station. However, this code may not be a callsign, but instead serve some other purpose. Radioscanner.ru identifies the owner of this station as a North-Caucasian military district communication center with callsign "Akacia" (ex-72nd communication center, Russian "72 узел связи штаба СКВО").

🔗 Mathematics

In mathematics, the Kolakoski sequence, sometimes also known as the Oldenburger–Kolakoski sequence, is an infinite sequence of symbols {1,2} that is the sequence of run lengths in its own run-length encoding. It is named after the recreational mathematician William Kolakoski (1944–97) who described it in 1965, but it was previously discussed by Rufus Oldenburger in 1939.

🔗 Video games 🔗 Anime and manga

The Tamagotchi Connection, known as Tamagotchi Plus in Japan and Tamagotchi Connexion in the UK, is a virtual pet in the Tamagotchi line of digital toys from Bandai. The Tamagotchi Connection is unique from prior models in that it uses infrared technology to connect and interact with other devices and was first released in 2004, 8 years after the first Tamagotchi toy. Using the device's infrared port, the virtual pet (referred to as a Tamagotchi) can make friends with other Tamagotchis, in addition to playing games, giving and receiving presents and having a baby.

Versions 1 to 4 of Tamagotchi Connection have 6 levels of friendship that can be viewed in the Friends List:

• Acquaintance (one smiley-face)
• Buddy (two smiley-faces)
• Friend (three smiley-faces)
• Good friend (four smiley-faces)
• Best friend (two love-hearts, two smiley-faces, during connection they may kiss)
• Partner (four love-hearts, during connection they will kiss and may have babies)

Versions 5 and 6 have different levels.

If the Tamagotchi cannot find a partner from another device to have babies with, a matchmaker will come, allowing the Tamagotchi to have a baby with a computer-controlled Tamagotchi character. This applies to versions 1 to 4 and 6 only. Version 5 introduces a Dating Show game in which the user must play to gain a CPU partner.

🔗 Economics

Veblen goods are types of luxury goods for which the quantity demanded increases as the price increases, an apparent contradiction of the law of demand, resulting in an upward-sloping demand curve. A higher price may make a product desirable as a status symbol in the practices of conspicuous consumption and conspicuous leisure. A product may be a Veblen good because it is a positional good, something few others can own.

Veblen goods are named after American economist Thorstein Veblen, who first identified conspicuous consumption as a mode of status-seeking in The Theory of the Leisure Class (1899). A corollary of the Veblen effect is that lowering the price decreases the quantity demanded.

🔗 India 🔗 Languages

Languages spoken in India belong to several language families, the major ones being the Indo-Aryan languages spoken by 78.05% of Indians and the Dravidian languages spoken by 19.64% of Indians. Languages spoken by the remaining 2.31% of the population belong to the Austroasiatic, Sino-Tibetan, Tai-Kadai and a few other minor language families and isolates. India (780) has the world's second highest number of languages, after Papua New Guinea (839).

Article 343 of the Indian constitution stated that the official language of the Union should become Hindi in Devanagari script instead of the extant English. Later, a constitutional amendment, The Official Languages Act, 1963, allowed for the continuation of English alongside Hindi in the Indian government indefinitely until legislation decides to change it. The form of numerals to be used for the official purposes of the Union are "the international form of Indian numerals", which are referred to as Arabic numerals in most English-speaking countries. Despite the misconceptions, Hindi is not the national language of India. The Constitution of India does not give any language the status of national language.

The Eighth Schedule of the Indian Constitution lists 22 languages, which have been referred to as scheduled languages and given recognition, status and official encouragement. In addition, the Government of India has awarded the distinction of classical language to Kannada, Malayalam, Odia, Sanskrit, Tamil and Telugu. Classical language status is given to languages which have a rich heritage and independent nature.

According to the Census of India of 2001, India has 122 major languages and 1599 other languages. However, figures from other sources vary, primarily due to differences in definition of the terms "language" and "dialect". The 2001 Census recorded 30 languages which were spoken by more than a million native speakers and 122 which were spoken by more than 10,000 people. Two contact languages have played an important role in the history of India: Persian and English. Persian was the court language during the Mughal period in India. It reigned as an administrative language for several centuries until the era of British colonisation. English continues to be an important language in India. It is used in higher education and in some areas of the Indian government. Hindi, the most commonly spoken language in India today, serves as the lingua franca across much of North and Central India. Bengali is the second most spoken and understood language in the country with a significant amount of speakers in Eastern and North- eastern regions. However, there have been concerns raised with Hindi being imposed in South India, most notably in the state of Tamil Nadu and Karnataka. Maharashtra, West Bengal, Assam, Punjab and other non-Hindi regions have also started to voice concerns about Hindi.

🔗 Trains 🔗 Trains/Monorail

The Wuppertaler Schwebebahn (Wuppertal Suspension Railway) is a suspension railway in Wuppertal, Germany.

Its full name is Anlage einer elektrischen Hochbahn (Schwebebahn), System Eugen Langen. ("Electric Elevated Railway (Suspension Railway) Installation, Eugen Langen System") It is the oldest electric elevated railway with hanging cars in the world and is a unique system.

Designed by Eugen Langen to sell to the city of Berlin, the installation with elevated stations was built in Barmen, Elberfeld and Vohwinkel between 1897 and 1903; the first track opened in 1901. The Schwebebahn is still in use today as a normal means of local public transport, moving 25 million passengers annually (2008).

The Schwebebahn runs along a route of 13.3 kilometres (8.3 mi), at a height of about 12 metres (39 ft) above the River Wupper between Oberbarmen and Sonnborner Straße (10 kilometres or 6.2 miles) and about 8 metres (26 ft) above the valley road between Sonnborner Straße and Vohwinkel (3.3 kilometres or 2.1 miles). At one point the railway crosses the A46 motorway. The entire trip takes about 30 minutes. The Schwebebahn operates within the VRR transport association and accepts tickets issued by the VRR companies.

Due to an accident in November 2018, the Schwebebahn was closed down for nearly nine months. It re-opened on 1 August 2019.

🔗 Heraldry and vexillology

A broad arrow, of which a pheon is a variant, is a stylised representation of a metal arrowhead, comprising a tang and two barbs meeting at a point. It is a symbol used traditionally in heraldry, most notably in England, and later by the British government to mark government property. It became particularly associated with the Board of Ordnance, and later the War Department and the Ministry of Defence. It was exported to other parts of the British Empire, where it was used in similar official contexts.

In heraldry, the arrowhead generally points downwards, whereas in other contexts it more usually points upwards.

🔗 Aviation 🔗 Crime 🔗 Lists 🔗 Novels 🔗 Correction and Detention Facilities 🔗 Popular Culture 🔗 Novels/Crime

A helicopter prison escape is made when an inmate escapes from a prison by means of a helicopter. This list includes prisoner escapes where a helicopter was used in an attempt to free prisoners from a place of internment, a prison or correctional facility.

One of the earliest instances of using a helicopter to escape a prison was the escape of Joel David Kaplan, nicknamed "Man Fan", on August 19, 1971 from the Santa Martha Acatitla in Mexico. Kaplan was a New York businessman who not only escaped the prison but eventually got out of Mexico and went on to write a book about his experience, The 10-Second Jailbreak.

France has had more recorded helicopter escape attempts than any other country, with at least 11. One of the most notable French jail breaks occurred in 1986, when the wife of bank robber Michel Vaujour studied for months to learn how to fly a helicopter. Using her newly acquired skills, she rented a white helicopter and flew low over Paris to pluck her husband off the roof of his fortress prison. Vaujour was later seriously wounded in a shootout with police, and his pilot wife was arrested.

The record for most helicopter escapes goes to convicted murderer Pascal Payet, who has used helicopters to escape from prisons in 2001, 2003, and most recently 2007.

Another multiple helicopter escapee is Vasilis Paleokostas who on February 22, 2009 escaped for the second time from the same prison. Because of this, many prisons have taken applicable precautions, such as nets or cables strung over open prison courtyards.

🔗 Mathematics

This is a list of mathematical symbols used in all branches of mathematics to express a formula or to represent a constant.

A mathematical concept is independent of the symbol chosen to represent it. For many of the symbols below, the symbol is usually synonymous with the corresponding concept (ultimately an arbitrary choice made as a result of the cumulative history of mathematics), but in some situations, a different convention may be used. For example, depending on context, the triple bar "≡" may represent congruence or a definition. However, in mathematical logic, numerical equality is sometimes represented by "≡" instead of "=", with the latter representing equality of well-formed formulas. In short, convention dictates the meaning.
