During the early stages of the Iraq War, members of the United States Army and the CIA committed a series of human rights violations and war crimes against detainees in the Abu Ghraib prison in Iraq, including physical and sexual abuse, torture, rape and the killing of Manadel al-Jamadi. The abuses came to public attention with the publication of photographs of the abuse by CBS News in April 2004. The incidents caused shock and outrage, receiving widespread condemnation within the United States and internationally.

The George W. Bush administration claimed that the abuses at Abu Ghraib were isolated incidents and not indicative of U.S. policy.^: 328 This was disputed by humanitarian organizations including the Red Cross, Amnesty International, and Human Rights Watch; these organizations stated that the abuses at Abu Ghraib were part of a wider pattern of torture and brutal treatment at American overseas detention centers, including those in Iraq, in Afghanistan, and at Guantanamo Bay.^: 328

Documents popularly known as the Torture Memos came to light a few years later. These documents, prepared in the months leading up to the 2003 invasion of Iraq by the United States Department of Justice, authorized certain enhanced interrogation techniques (generally held to involve torture) of foreign detainees. The memoranda also argued that international humanitarian laws, such as the Geneva Conventions, did not apply to American interrogators overseas. Several subsequent U.S. Supreme Court decisions, including Hamdan v. Rumsfeld (2006), have overturned Bush administration policy, ruling that the Geneva Conventions do apply.

In response to the events at Abu Ghraib, the United States Department of Defense removed 17 soldiers and officers from duty. Eleven soldiers were charged with dereliction of duty, maltreatment, aggravated assault and battery. Between May 2004 and April 2006, these soldiers were court-martialed, convicted, sentenced to military prison, and dishonorably discharged from service. Two soldiers, found to have perpetrated many of the worst offenses at the prison, Specialist Charles Graner and PFC Lynndie England, were subject to more severe charges and received harsher sentences. Graner was convicted of assault, battery, conspiracy, maltreatment of detainees, committing indecent acts and dereliction of duty; he was sentenced to 10 years imprisonment and loss of rank, pay and benefits. England was convicted of conspiracy, maltreating detainees and committing an indecent act and sentenced to three years in prison. Brigadier General Janis Karpinski, the commanding officer of all detention facilities in Iraq, was reprimanded and demoted to the rank of colonel. Several more military personnel who were accused of perpetrating or authorizing the measures, including many of higher rank, were not prosecuted. In 2004, President George W. Bush and Defense Secretary Donald Rumsfeld apologized for the Abu Ghraib abuses.

The Royal Canadian Air Force Exercise Plans are two exercise plans developed for the Royal Canadian Air Force (RCAF) by Dr. Bill Orban in the late 1950s, first published in 1961. The 5BX plan (Five Basic Exercises) was developed for men; a corresponding program was developed for women under the name XBX (Ten Basic Exercises) and the two plans were subsequently published together as one book. The popularity of the programs in many countries around the world helped to launch modern fitness culture.

An amplituhedron is a geometric structure introduced in 2013 by Nima Arkani-Hamed and Jaroslav Trnka. It enables simplified calculation of particle interactions in some quantum field theories. In planar N = 4 supersymmetric Yang–Mills theory, also equivalent to the perturbative topological B model string theory in twistor space, an amplituhedron is defined as a mathematical space known as the positive Grassmannian.

Amplituhedron theory challenges the notion that spacetime locality and unitarity are necessary components of a model of particle interactions. Instead, they are treated as properties that emerge from an underlying phenomenon.

The connection between the amplituhedron and scattering amplitudes is at present a conjecture that has passed many non-trivial checks, including an understanding of how locality and unitarity arise as consequences of positivity. Research has been led by Nima Arkani-Hamed. Edward Witten described the work as "very unexpected" and said that "it is difficult to guess what will happen or what the lessons will turn out to be".

🔗 Norse history and culture

In Norse mythology, Ragnarök ( (listen); Old Norse: Ragnarǫk) is a series of events, including a great battle, foretelling the death of numerous great figures (including the gods Odin, Thor, Týr, Freyr, Heimdallr, and Loki), natural disasters, and the submersion of the world in water. After these events, the world will rise again, cleansed and fertile, the surviving and returning gods will meet and the world will be repopulated by two human survivors. Ragnarök is an important event in Norse mythology and has been the subject of scholarly discourse and theory in the history of Germanic studies.

The event is attested primarily in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda, written in the 13th century by Snorri Sturluson. In the Prose Edda and in a single poem in the Poetic Edda, the event is referred to as Ragnarøkkr (Old Norse for 'Twilight of the Gods'), a usage popularised by 19th-century composer Richard Wagner with the title of the last of his Der Ring des Nibelungen operas, Götterdämmerung (1876), which is "Twilight of the Gods" in German.

🔗 Architecture

The Frankfurt kitchen was a milestone in domestic architecture, considered the forerunner of modern fitted kitchens, for it realised for the first time a kitchen built after a unified concept, designed to enable efficient work and to be built at low cost. It was designed in 1926 by Austrian architect Margarete Schütte-Lihotzky for architect Ernst May's social housing project New Frankfurt in Frankfurt, Germany. Some 10,000 units were built in the late 1920s in Frankfurt.

🔗 Human rights 🔗 China 🔗 Islam 🔗 Correction and Detention Facilities

The Xinjiang re-education camps, officially called Vocational Education and Training Centers by the government of the People's Republic of China, are internment camps that have been operated by the Xinjiang Uygur Autonomous Region government for the purpose of indoctrinating Uyghurs since 2017 as part of a "people's war on terror" announced in 2014. The camps were established under General Secretary Xi Jinping's administration and led by party secretary, Chen Quanguo. These camps are reportedly operated outside the legal system; many Uyghurs have reportedly been interned without trial and no charges have been levied against them. Local authorities are reportedly holding hundreds of thousands of Uyghurs in these camps as well as other ethnic minority groups, for the stated purpose of countering extremism and terrorism and promoting sinicization.

As of 2018, it was estimated that the Chinese authorities may have detained hundreds of thousands, perhaps a million, Uyghurs, Kazakhs, Kyrgyz and other ethnic Turkic Muslims, Christians as well as some foreign citizens such as Kazakhstanis, who are being held in these secretive internment camps which are located throughout the region. In May 2018, Randall Schriver of the United States Department of Defense claimed that "at least a million but likely closer to three million citizens" were imprisoned in detention centers in a strong condemnation of the "concentration camps". In August 2018, a United Nations human rights panel said that it had received many credible reports that 1 million ethnic Uyghurs in China have been held in "re-education camps". There have also been multiple reports from media, politicians and researchers comparing the camps to the Chinese Cultural Revolution.

In 2019, the United Nations ambassadors from 22 nations, including Australia, Canada, France, Germany, Japan, and the United Kingdom signed a letter condemning China's mass detention of the Uyghurs and other minority groups, urging the Chinese government to close the camps. Conversely, a joint statement was signed by 37 states commending China's counter-terrorism program in Xinjiang, including Algeria, the DR Congo, Russia, Saudi Arabia, Syria, Iran, Iraq, Pakistan, North Korea, Egypt, Nigeria, the Philippines and Sudan.

On August 1, 1942, the American Federation of Musicians, at the instigation of union president James C. Petrillo, began a strike against the major American record companies because of disagreements over royalty payments. Beginning at midnight, July 31, 1942, no union musician could make commercial recordings for any commercial record company. That meant that a union musician was allowed to participate on radio programs and other kinds of musical entertainment, but not in a recording session. The 1942–1944 musicians' strike remains the longest strike in entertainment history.

The strike did not affect musicians performing on live radio shows, in concerts, or, after October 27, 1943, on special recordings made by the record companies for V-Discs for distribution to the armed forces fighting World War II, because V-Discs were not available to the general public. However, the union did frequently threaten to withdraw musicians from the radio networks to punish individual network affiliates who were deemed "unfair" for violating the union's policy on recording network shows for repeat broadcasts.

The strike had a major impact on the American musical scene. At the time, union bands dominated popular music; after the strike, and partly as a result of it, the big bands began to decline and vocalists began to dominate popular music.
