π Uyghur Genocide
The Uyghur genocide is the ongoing series of human rights abuses perpetrated by the government of China against the Uyghur people and other ethnic and religious minorities in and around the Xinjiang Uygur Autonomous Region (XUAR) of the People's Republic of China. Since 2014, the Chinese government, under the direction of the Chinese Communist Party (CCP) during the administration of CCP general secretary Xi Jinping, has pursued policies leading to more than one million Muslims (the majority of them Uyghurs) being held in secretive internment camps without any legal process in what has become the largest-scale and most systematic detention of ethnic and religious minorities since the Holocaust and World War II. Thousands of mosques have been destroyed or damaged, and hundreds of thousands of children have been forcibly separated from their parents and sent to boarding schools.
These policies have been described by critics as the forced assimilation of Xinjiang, as well as an ethnocide or cultural genocide. Some governments, activists, independent NGOs, human rights experts, academics, government officials, and the East Turkistan Government-in-Exile have called it a genocide.
In particular, critics have highlighted the concentration of Uyghurs in state-sponsored internment camps, suppression of Uyghur religious practices, political indoctrination, severe ill-treatment, as well as extensive evidence and other testimonials detailing human rights abuses including forced sterilization, contraception, abortion, and infanticides. Chinese government statistics show that from 2015 to 2018, birth rates in the mostly Uyghur regions of Hotan and Kashgar fell by more than 60%. In the same period, the birth rate of the whole country decreased by 9.69%, from 12.07 to 10.9 per 1,000 people. Chinese authorities acknowledged that birth rates dropped by almost a third in 2018 in Xinjiang, but denied reports of forced sterilization and genocide. Birth rates fell nearly 24% in 2019 (compared to a nationwide decrease of just 4.2%).
International reactions have been sharply divided, with dozens of United Nations (UN) member states issuing opposing letters to the United Nations Human Rights Council in support and condemnation of China's policies in Xinjiang in 2020. In December 2020, the International Criminal Court declined to take investigative action against China on the basis of not having jurisdiction over China for most of the alleged crimes. The United States was the first country to declare the human rights abuses a genocide, announcing its determination on January 19, 2021, although the US State Department's Office of the Legal Adviser concluded that there was insufficient evidence to prove genocide. This was followed by Canada's House of Commons and the Dutch parliament each passing a non-binding motion in February 2021 to recognize China's actions as genocide. Later, in April 2021, the United Kingdom's House of Commons unanimously passed a non-binding motion to recognize the actions as genocide. In May 2021 the New Zealand parliament unanimously declared that "severe human rights abuses" were occurring against the Uyghur people in China and the Seimas of Lithuania passed a resolution that recognized the Chinese government's abuse of the Uyghurs as a genocide.
π Supramolecular Chemistry
Supramolecular chemistry refers to the branch of chemistry concerning chemical systems composed of a discrete number of molecules. The strength of the forces responsible for spatial organization of the system range from weak intermolecular forces, electrostatic charge, or hydrogen bonding to strong covalent bonding, provided that the electronic coupling strength remains small relative to the energy parameters of the component. While traditional chemistry concentrates on the covalent bond, supramolecular chemistry examines the weaker and reversible non-covalent interactions between molecules. These forces include hydrogen bonding, metal coordination, hydrophobic forces, van der Waals forces, piβpi interactions and electrostatic effects.
Important concepts advanced by supramolecular chemistry include molecular self-assembly, molecular folding, molecular recognition, hostβguest chemistry, mechanically-interlocked molecular architectures, and dynamic covalent chemistry. The study of non-covalent interactions is crucial to understanding many biological processes that rely on these forces for structure and function. Biological systems are often the inspiration for supramolecular research.

π Dancing mania
Dancing mania (also known as dancing plague, choreomania, St. John's Dance and St. Vitus's Dance) was a social phenomenon that occurred primarily in mainland Europe between the 14th and 17th centuries. It involved groups of people dancing erratically, sometimes thousands at a time. The mania affected men, women, and children who danced until they collapsed from exhaustion. One of the first major outbreaks was in Aachen, in the Holy Roman Empire, in 1374, and it quickly spread throughout Europe; one particularly notable outbreak occurred in Strasbourg in 1518, also in the Holy Roman Empire.
Affecting thousands of people across several centuries, dancing mania was not an isolated event, and was well documented in contemporary reports. It was nevertheless poorly understood, and remedies were based on guesswork. Often musicians accompanied dancers, due to a belief that music would treat the mania, but this tactic sometimes backfired by encouraging more to join in. There is no consensus among modern-day scholars as to the cause of dancing mania.
The several theories proposed range from religious cults being behind the processions to people dancing to relieve themselves of stress and put the poverty of the period out of their minds. It is speculated to have been a mass psychogenic illness, in which physical symptoms with no known physical cause are observed to affect a group of people, as a form of social influence.

π Potato Paradox
The potato paradox is a mathematical calculation that has a counter-intuitive result. The Universal Book of Mathematics states the problem as follows:
Fred brings home 100 kg of potatoes, which (being purely mathematical potatoes) consist of 99% water. He then leaves them outside overnight so that they consist of 98% water. What is their new weight? The surprising answer is 50 kg.
In Quine's classification of paradoxes, the potato paradox is a veridical paradox.

π Gambling on Papal Conclaves
Gambling on papal elections has at least a 500-year history. Betting on 16th-century papal conclaves are among the first documented examples of gambling on election outcomes. During the same period, gambling was also common on the outcomes of secular Italian elections, such as that of the Doge of Venice. Leighton Vaughan Williams and David Paton employ a unique dataset to investigate betting on the 2013 papal election, set within the context of the history of betting on papal conclaves.

π List of countries by home ownership rate
This is a list of countries and territories by home ownership rate, which is the ratio of owner-occupied units to total residential units in a specified area.
π Penny Universities
English coffeehouses in the 17th and 18th centuries were public social places where men would meet for conversation and commerce. For the price of a penny, customers purchased a cup of coffee and admission. Travellers introduced coffee as a beverage to England during the mid-17th century; previously it had been consumed mainly for its supposed medicinal properties. Coffeehouses also served tea and hot chocolate as well as a light meal.
The historian Brian Cowan describes English coffeehouses as "places where people gathered to drink coffee, learn the news of the day, and perhaps to meet with other local residents and discuss matters of mutual concern." Topics like the Yellow Fever would also be discussed. The absence of alcohol created an atmosphere in which it was possible to engage in more serious conversation than in an alehouse. Coffeehouses also played an important role in the development of financial markets and newspapers.
Topics discussed included politics and political scandals, daily gossip, fashion, current events, and debates surrounding philosophy and the natural sciences. Historians often associate English coffeehouses, during the 17th and 18th centuries, with the intellectual and cultural history of the Age of Enlightenment: they were an alternate sphere, supplementary to the university. Political groups frequently used coffeehouses as meeting places.
π Curse of knowledge
The curse of knowledge is a cognitive bias that occurs when an individual, communicating with other individuals, unknowingly assumes that the others have the background to understand. This bias is also called by some authors the curse of expertise, although that term is also used to refer to various other phenomena.
For example, in a classroom setting, teachers have difficulty teaching novices because they cannot put themselves in the position of the student. A brilliant professor might no longer remember the difficulties that a young student encounters when learning a new subject. This curse of knowledge also explains the danger behind thinking about student learning based on what appears best to faculty members, as opposed to what has been verified with students.

π Why you hate tasks that you love, when they become your day job
Reactance is an unpleasant motivational arousal (reaction) to offers, persons, rules, or regulations that threaten or eliminate specific behavioral freedoms. Reactance occurs when a person feels that someone or something is taking away their choices or limiting the range of alternatives.
Reactance can occur when someone is heavily pressured to accept a certain view or attitude. Reactance can cause the person to adopt or strengthen a view or attitude that is contrary to what was intended, and also increases resistance to persuasion. People using reverse psychology are playing on reactance, attempting to influence someone to choose the opposite of what they request.
Some individuals are naturally high in reactance, a personality characteristic called trait reactance.

π Herfindahl Index
The Herfindahl index (also known as HerfindahlβHirschman Index, HHI, or sometimes HHI-score) is a measure of the size of firms in relation to the industry and an indicator of the amount of competition among them. Named after economists Orris C. Herfindahl and Albert O. Hirschman, it is an economic concept widely applied in competition law, antitrust and also technology management. It is defined as the sum of the squares of the market shares of the firms within the industry (sometimes limited to the 50 largest firms), where the market shares are expressed as fractions. The result is proportional to the average market share, weighted by market share. As such, it can range from 0 to 1.0, moving from a huge number of very small firms to a single monopolistic producer. Increases in the Herfindahl index generally indicate a decrease in competition and an increase of market power, whereas decreases indicate the opposite. Alternatively, if whole percentages are used, the index ranges from 0 to 10,000 "points". For example, an index of .25 is the same as 2,500 points.
The major benefit of the Herfindahl index in relationship to such measures as the concentration ratio is that it gives more weight to larger firms.
The measure is essentially equivalent to the Simpson diversity index, which is a diversity index used in ecology; the inverse participation ratio (IPR) in physics; and the effective number of parties index in politics.
