"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.

Pinkerton is a private security guard and detective agency established around 1850 in the United States by Scottish-born American cooper Allan Pinkerton and Chicago attorney Edward Rucker as the North-Western Police Agency, which later became Pinkerton & Co, and finally the Pinkerton National Detective Agency. It is currently a subsidiary of Swedish-based Securitas AB. Pinkerton became famous when he claimed to have foiled the Baltimore Plot to assassinate president-elect Abraham Lincoln in 1861. Lincoln later hired Pinkerton agents to conduct espionage against the Confederacy and act as his personal security during the American Civil War.

The Pinkerton National Detective Agency hired women and minorities from its founding because they were useful as spies, a practice uncommon at the time. At the height of their power, the Pinkerton Detective Agency was the largest private law enforcement organization in the world.

Following the Civil War, the Pinkertons began conducting operations against organized labor. During the labor strikes of the late 19th and early 20th centuries, businesses hired the Pinkerton Agency to infiltrate unions, supply guards, keep strikers and suspected unionists out of factories, and recruit goon squads to intimidate workers. During the Homestead Strike of 1892, Pinkerton agents were called in to reinforce the strikebreaking measures of industrialist Henry Clay Frick, who was acting on behalf of Andrew Carnegie, the head of Carnegie Steel. Tensions between the workers and strikebreakers erupted into violence which led to the deaths of three Pinkerton agents and nine steelworkers. During the late nineteenth century, the Pinkertons were also hired as guards in coal, iron, and lumber disputes in Illinois, Michigan, New York, Pennsylvania, and West Virginia. Pinkertons were also involved in other strikes such as the Great Railroad Strike of 1877.

During the 20th century, Pinkerton rebranded itself into a personal security and risk management firm. The company has continued to exist in various forms through to the present day, and is now a division of the Swedish security company Securitas AB, operating as "Pinkerton Consulting & Investigations, Inc. d.b.a. Pinkerton Corporate Risk Management". The former Government Services division, PGS, now operates as "Securitas Critical Infrastructure Services, Inc.".

🔗 Food and drink 🔗 Chemistry

The Maillard reaction ( my-YAR; French: [majaʁ]) is a chemical reaction between amino acids and reducing sugars that gives browned food its distinctive flavor. Seared steaks, fried dumplings, cookies and other kinds of biscuits, breads, toasted marshmallows, and many other foods undergo this reaction. It is named after French chemist Louis-Camille Maillard, who first described it in 1912 while attempting to reproduce biological protein synthesis.

The reaction is a form of non-enzymatic browning which typically proceeds rapidly from around 140 to 165 °C (280 to 330 °F). Many recipes call for an oven temperature high enough to ensure that a Maillard reaction occurs. At higher temperatures, caramelization (the browning of sugars, a distinct process) and subsequently pyrolysis (final breakdown leading to burning) become more pronounced.

The reactive carbonyl group of the sugar reacts with the nucleophilic amino group of the amino acid, and forms a complex mixture of poorly characterized molecules responsible for a range of aromas and flavors. This process is accelerated in an alkaline environment (e.g., lye applied to darken pretzels; see lye roll), as the amino groups (RNH₃⁺ → RNH₂) are deprotonated, and hence have an increased nucleophilicity. This reaction is the basis for many of the flavoring industry's recipes. At high temperatures, a probable carcinogen called acrylamide can form. This can be discouraged by heating at a lower temperature, adding asparaginase, or injecting carbon dioxide.

In the cooking process, Maillard reactions can produce hundreds of different flavor compounds depending on the chemical constituents in the food, the temperature, the cooking time, and the presence of air. These compounds, in turn, often break down to form yet more new flavor compounds. Flavor scientists have used the Maillard reaction over the years to make artificial flavors.

The curse of dimensionality refers to various phenomena that arise when analyzing and organizing data in high-dimensional spaces (often with hundreds or thousands of dimensions) that do not occur in low-dimensional settings such as the three-dimensional physical space of everyday experience. The expression was coined by Richard E. Bellman when considering problems in dynamic programming.

Cursed phenomena occur in domains such as numerical analysis, sampling, combinatorics, machine learning, data mining and databases. The common theme of these problems is that when the dimensionality increases, the volume of the space increases so fast that the available data become sparse. This sparsity is problematic for any method that requires statistical significance. In order to obtain a statistically sound and reliable result, the amount of data needed to support the result often grows exponentially with the dimensionality. Also, organizing and searching data often relies on detecting areas where objects form groups with similar properties; in high dimensional data, however, all objects appear to be sparse and dissimilar in many ways, which prevents common data organization strategies from being efficient.

The Marsh Chapel Experiment, also called the "Good Friday Experiment", was a 1962 experiment conducted on Good Friday at Boston University's Marsh Chapel. Walter N. Pahnke, a graduate student in theology at Harvard Divinity School, designed the experiment under the supervision of Timothy Leary, Richard Alpert, and the Harvard Psilocybin Project. Pahnke's experiment investigated whether psilocybin (the active principle in psilocybin mushrooms) would act as a reliable entheogen in religiously predisposed subjects.

🔗 Linguistics

In linguistics, a mass noun, uncountable noun, non-count noun, uncount noun, or just uncountable, is a noun with the syntactic property that any quantity of it is treated as an undifferentiated unit, rather than as something with discrete elements. Non-count nouns are distinguished from count nouns.

Given that different languages have different grammatical features, the actual test for which nouns are mass nouns may vary between languages. In English, mass nouns are characterized by the impossibility of being directly modified by a numeral without specifying a unit of measurement and by the impossibility of being combined with an indefinite article (a or an). Thus, the mass noun "water" is quantified as "20 litres of water" while the count noun "chair" is quantified as "20 chairs". However, both mass and count nouns can be quantified in relative terms without unit specification (e.g., "so much water", "so many chairs").

Mass nouns have no concept of singular and plural, although in English they take singular verb forms. However, many mass nouns in English can be converted to count nouns, which can then be used in the plural to denote (for instance) more than one instance or variety of a certain sort of entity – for example, "Many cleaning agents today are technically not soaps [i.e. types of soap], but detergents," or "I drank about three beers [i.e. bottles or glasses of beer]".

Some nouns can be used indifferently as mass or count nouns, e.g., three cabbages or three heads of cabbage; three ropes or three lengths of rope. Some have different senses as mass and count nouns: paper is a mass noun as a material (three reams of paper, one sheet of paper), but a count noun as a unit of writing ("the students passed in their papers").

The Inco Superstack in Sudbury, Ontario, with a height of 381 metres (1,250 ft), is the tallest chimney in Canada and the Western hemisphere, and the second tallest freestanding chimney in the world after the GRES-2 Power Station in Kazakhstan. It is also the second tallest freestanding structure of any type in Canada, behind the CN Tower but ahead of First Canadian Place. It is the 51st tallest freestanding structure in the world. The Superstack is located on top of the largest nickel smelting operation in the world at Vale's Copper Cliff processing facility in the city of Greater Sudbury.

In 2018, Vale announced that the stack would be decommissioned and dismantled beginning in 2020. Two new, smaller stacks were constructed under the company's Clean Atmospheric Emissions Reduction Project. In July 2020, Vale announced that the Superstack had been officially taken out of service, but would remain operational in standby mode for two more months as a backup in the event of a malfunction in the new system, following which the dismantling of the Superstack would begin. As of August 2021, however, Vale has not yet announced the awarding of a demolition contract on the Superstack, and it remains unknown when demolition will actually begin.

In addition to further reducing sulphur dioxide emissions by 85 per cent, the decommissioning of the stack is expected to cut the complex's natural gas consumption in half.

Height can significantly influence success in sports, depending on how the design of the sport is linked to factors that are height-biased due to physics and biology. The balance of the intricate array of links will determine the degree to which height plays a role in success, if any.

On personal computers, the turbo button is a button which provides two run states for the computer: normal speed or an enhanced "turbo" speed. It was relatively common on personal computers using the Intel 80286, Intel 80386 and Intel 80486 processors, from the mid 1980s to mid 1990s.

The name is inspired by turbocharger, a turbine-driven forced induction device that increases an engine's power and efficiency.
