Great ape personhood is a movement to extend personhood and some legal protections to the non-human members of the Hominidae or great ape family: chimpanzees, bonobos, gorillas, and orangutans.

Advocates include primatologists Jane Goodall and Dawn Prince-Hughes, evolutionary biologist Richard Dawkins, philosophers Paola Cavalieri and Peter Singer, and legal scholar Steven Wise.

🔗 Psychology

The 'doorway effect' or ‘location updating effect’ is a replicable psychological phenomenon characterized by short-term memory loss when passing through a doorway or moving from one location to another. We tend to forget items of recent significance immediately after crossing a boundary and often forget what we were thinking about or planning on doing upon entering a different room. Research suggests that this phenomenon occurs both at literal boundaries (e.g., moving from one room to another via a door) and metaphorical boundaries (e.g., imagining traversing a doorway, or even when moving from one desktop window to another on a computer).

Memory is organized around specific events or episodes, such as attending a lecture or having a family meal, rather than being a continuous stream interrupted by sleep. This organization is called episodic memory, which involves receiving and storing information about events that are temporarily dated, along with their time and place relationships.

Numerous psychological studies have indicated that the external context, including the location where events occur, plays a significant role in how memories are separated. This context helps establish distinctions between different remembered events. Memories of events that happen in the environment we're currently in are easier to access compared to those from different places. As a result, when we experience spatial changes and move to a different location, it can act as a boundary marker that separates and categorizes our continuous flow of memories into distinct segments.

The Tiananmen Square protests, also known as the June Fourth Incident (Chinese: 六四事件; pinyin: liùsì shìjiàn) in China, were student-led demonstrations held in Tiananmen Square, Beijing during 1989. In what is known as the Tiananmen Square Massacre (Chinese: 天安门大屠杀; pinyin: Tiān'ānmén dà túshā), troops armed with assault rifles and accompanied by tanks fired at the demonstrators and those trying to block the military's advance into Tiananmen Square. The protests started on 15 April and were forcibly suppressed on 4 June when the government declared martial law and sent the People's Liberation Army to occupy parts of central Beijing. Estimates of the death toll vary from several hundred to several thousand, with thousands more wounded. The popular national movement inspired by the Beijing protests is sometimes called the '89 Democracy Movement (Chinese: 八九民运; pinyin: Bājiǔ mínyùn) or the Tiananmen Square Incident (Chinese: 天安门事件; pinyin: Tiān'ānmén shìjiàn).

The protests were precipitated by the death of pro-reform Chinese Communist Party (CCP) general secretary Hu Yaobang in April 1989 amid the backdrop of rapid economic development and social change in post-Mao China, reflecting anxieties among the people and political elite about the country's future. The reforms of the 1980s had led to a nascent market economy that benefited some people but seriously disadvantaged others, and the one-party political system also faced a challenge to its legitimacy. Common grievances at the time included inflation, corruption, limited preparedness of graduates for the new economy, and restrictions on political participation. Although they were highly disorganized and their goals varied, the students called for greater accountability, constitutional due process, democracy, freedom of the press, and freedom of speech. At the height of the protests, about one million people assembled in the Square.

As the protests developed, the authorities responded with both conciliatory and hardline tactics, exposing deep divisions within the party leadership. By May, a student-led hunger strike galvanized support around the country for the demonstrators, and the protests spread to some 400 cities. Among the CCP's top leadership, Premier Li Peng and Party Elders Li Xiannian and Wang Zhen called for decisive action through violent suppression of the protesters, and ultimately managed to win over Paramount Leader Deng Xiaoping and President Yang Shangkun to their side. On 20 May, the State Council declared martial law. They mobilized as many as ~300,000 troops to Beijing. The troops advanced into central parts of Beijing on the city's major thoroughfares in the early morning hours of 4 June, killing both demonstrators and bystanders in the process. The military operations were under the overall command of General Yang Baibing, half-brother of President Yang Shangkun.

The international community, human rights organizations, and political analysts condemned the Chinese government for the massacre. Western countries imposed arms embargoes on China. The Chinese government made widespread arrests of protesters and their supporters, suppressed other protests around China, expelled foreign journalists, strictly controlled coverage of the events in the domestic press, strengthened the police and internal security forces, and demoted or purged officials it deemed sympathetic to the protests. More broadly, the suppression ended the political reforms begun in 1986 and halted the policies of liberalization of the 1980s, which were only partly resumed after Deng Xiaoping's Southern Tour in 1992. Considered a watershed event, reaction to the protests set limits on political expression in China that have lasted up to the present day. Remembering the protests is widely associated with questioning the legitimacy of CCP rule and remains one of the most sensitive and most widely censored topics in China.

Cecilia Helena Payne-Gaposchkin (née Payne; (1900-05-10)May 10, 1900 – (1979-12-07)December 7, 1979) was a British-born American astronomer and astrophysicist who proposed in her 1925 doctoral thesis that stars were composed primarily of hydrogen and helium. Her groundbreaking conclusion was initially rejected because it contradicted the scientific wisdom of the time, which held that there were no significant elemental differences between the Sun and Earth. Independent observations eventually proved she was actually correct

Project Babylon was a space gun project commissioned by then Iraqi president Saddam Hussein. It involved building a series of "superguns". The design was based on research from the 1960s Project HARP led by the Canadian artillery expert Gerald Bull. There were most likely four different devices in the program.

The project began in 1988; it was halted in 1990 after Bull was assassinated, and parts of the superguns were seized in transit around Europe. The components that remained in Iraq were destroyed by the United Nations after the 1991 Persian Gulf War.

🔗 Time 🔗 Geology

Before Present (BP) years is a time scale used mainly in archaeology, geology and other scientific disciplines to specify when events occurred in the past. Because the "present" time changes, standard practice is to use 1 January 1950 as the commencement date (epoch) of the age scale, reflecting the origin of practical radiocarbon dating in the 1950s. The abbreviation "BP" has been interpreted retrospectively as "Before Physics"; that refers to the time before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, making dating after that time likely to be unreliable.

In a convention that is not always observed, many sources restrict the use of BP dates to those produced with radiocarbon dating; the alternative notation RCYBP is explicitly Radio Carbon Years Before Present.

The North American Phalanx was a secular utopian socialist commune located in Colts Neck Township, Monmouth County, New Jersey. The community was the longest-lived of about 30 Fourierist Associations in the United States which emerged during a brief burst of popularity during the decade of the 1840s.

The North American Phalanx was established in September 1843 and included the active participation of writer Albert Brisbane and newspaper publisher Horace Greeley, two of the leading figures of the Fourierist movement. The Association was disbanded in January 1856, following a catastrophic fire which destroyed a number of the community's productive enterprises. At the time of its termination it was the last of about 30 Fourierist Associations established during the 1840s still in existence and thus was the longest-lived.

The main residential dwelling of the phalanx, a three-story wooden structure, stood vacant until it was itself destroyed by fire in November 1972.
