In July 1184, Henry VI, King of Germany (later Holy Roman Emperor), held court at a Hoftag in the Petersberg Citadel in Erfurt. On the morning of 26 July, the combined weight of the assembled nobles caused the wooden second story floor of the building to collapse and most of them fell through into the latrine cesspit below the ground floor, where about 60 of them drowned in liquid excrement. This event is called Erfurter Latrinensturz (lit. 'Erfurt latrine fall') in several German sources.

🔗 Visual arts

The Voyage of Life is a series of four paintings created by Thomas Cole in 1842, representing an allegory of the four stages of human life. The paintings, Childhood, Youth, Manhood, and Old Age, depict a voyager who travels in a boat on a river through the mid-19th-century American wilderness. In each painting the voyager rides the boat on the River of Life accompanied by a guardian angel. The landscape, each reflecting one of the four seasons of the year, plays a major role in conveying the story. With each installment the boat's direction of travel is reversed from the previous picture. In childhood, the infant glides from a dark cave into a rich, green landscape. As a youth, the boy takes control of the boat and aims for a shining castle in the sky. In manhood, the adult relies on prayer and religious faith to sustain him through rough waters and a threatening landscape. Finally, the man becomes old and the angel guides him to heaven across the waters of eternity.

The Salem witchcraft trial of 1878, also known as the Ipswich witchcraft trial and the second Salem witch trial, was an American civil case held in May 1878 in Salem, Massachusetts, in which Lucretia L. S. Brown, an adherent of the Christian Science religion, accused fellow Christian Scientist Daniel H. Spofford of attempting to harm her through his "mesmeric" mental powers. By 1918, it was considered the last witchcraft trial held in the United States. The case garnered significant attention for its startling claims and the fact that it took place in Salem, the scene of the 1692 Salem witch trials. The judge dismissed the case.

🔗 Physics 🔗 Physics/relativity

In theoretical physics, particularly in discussions of gravitation theories, Mach's principle (or Mach's conjecture) is the name given by Einstein to an imprecise hypothesis often credited to the physicist and philosopher Ernst Mach. The hypothesis attempted to explain how rotating objects, such as gyroscopes and spinning celestial bodies, maintain a frame of reference.

The proposition is that the existence of absolute rotation (the distinction of local inertial frames vs. rotating reference frames) is determined by the large-scale distribution of matter, as exemplified by this anecdote:

You are standing in a field looking at the stars. Your arms are resting freely at your side, and you see that the distant stars are not moving. Now start spinning. The stars are whirling around you and your arms are pulled away from your body. Why should your arms be pulled away when the stars are whirling? Why should they be dangling freely when the stars don't move?

Mach's principle says that this is not a coincidence—that there is a physical law that relates the motion of the distant stars to the local inertial frame. If you see all the stars whirling around you, Mach suggests that there is some physical law which would make it so you would feel a centrifugal force. There are a number of rival formulations of the principle, often stated in vague ways like "mass out there influences inertia here". A very general statement of Mach's principle is "local physical laws are determined by the large-scale structure of the universe".

Mach's concept was a guiding factor in Einstein's development of the general theory of relativity. Einstein realized that the overall distribution of matter would determine the metric tensor which indicates which frame is stationary with respect to rotation. Frame-dragging and conservation of gravitational angular momentum makes this into a true statement in the general theory in certain solutions. But because the principle is so vague, many distinct statements have been made which would qualify as a Mach principle, and some of which are false. The Gödel rotating universe is a solution of the field equations that is designed to disobey Mach's principle in the worst possible way. In this example, the distant stars seem to be revolving faster and faster as one moves further away. This example does not completely settle the question of the physical relevance of the principle because it has closed timelike curves.

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.

Gold is a 1934 German science fiction film directed by Karl Hartl. The film involves a British scientist who is attempting to create a device that turns base materials into gold. He later forces the German scientist's assistant Werner Holk (Hans Albers), who was working on a similar experiment, to come to his underwater nuclear reactor to help him. Gold was made in both German-language and French-language versions with Brigitte Helm reprising her role in both.

Network is a 1976 American satirical black comedy-drama film released by Metro-Goldwyn-Mayer, written by Paddy Chayefsky and directed by Sidney Lumet. It is about a fictional television network, UBS, and its struggle with poor ratings. The film stars Faye Dunaway, William Holden, Peter Finch (in his final film role), Robert Duvall, Wesley Addy, Ned Beatty, and Beatrice Straight.

Network received widespread critical acclaim, with particular praise for the performances. The film was a commercial success, with nine Oscar nominations at the 49th Academy Awards, including Best Picture, that led to four wins: Best Actor (Finch), Best Actress (Dunaway), Best Supporting Actress (Straight), and Best Original Screenplay.

In 2000, the film was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant". In 2002, it was inducted into the Producers Guild of America Hall of Fame as a film that has "set an enduring standard for American entertainment". In 2005, the two Writers Guilds of America voted Chayefsky's script one of the 10 greatest screenplays in the history of cinema. In 2007, the film was 64th among the 100 greatest American films as chosen by the American Film Institute, a ranking slightly higher than the one AFI had given it ten years earlier.

Yahoo! Pipes was a web application from Yahoo! that provided a graphical user interface for building data mashups that aggregate web feeds, web pages, and other services, creating Web-based apps from various sources, and publishing those apps. The application worked by enabling users to "pipe" information from different sources and then set up rules for how that content should be modified (for example, filtering). Other than the pipe editing page, the website had a documentation page and a discussion page. The documentation page contained information about pipes including guides for the pipe editor and troubleshooting. The discussion page enabled users to discuss the pipes with other users.

In Canada, the Indian residential school system was a network of boarding schools for Indigenous peoples which amounted to cultural genocide. The network was funded by the Canadian government's Department of Indian Affairs and administered by Christian churches. The school system was created to isolate Indigenous children from the influence of their own native culture and religion in order to assimilate them into the dominant Canadian culture.^: 42 Over the course of the system's more than hundred-year existence, around 150,000 children were placed in residential schools nationally.^: 2–3 By the 1930s about 30 percent of Indigenous children were believed to be attending residential schools. The number of school-related deaths remains unknown due to incomplete records. Estimates range from 3,200 to over 30,000.

The system had its origins in laws enacted before Confederation, but it was primarily active from the passage of the Indian Act in 1876, under Prime Minister Alexander MacKenzie. Under Prime Minister John A. Macdonald, the government adopted the residential industrial school system of the United States, a partnership between the government and various church organizations. An amendment to the Indian Act in 1894, under Prime Minister Mackenzie Bowell, made attendance at day schools, industrial schools, or residential schools compulsory for First Nations children. Due to the remote nature of many communities, school locations meant that for some families, residential schools were the only way to comply. The schools were intentionally located at substantial distances from Indigenous communities to minimize contact between families and their children. Indian Commissioner Hayter Reed argued for schools at greater distances to reduce family visits, which he thought counteracted efforts to assimilate Indigenous children. Parental visits were further restricted by the use of a pass system designed to confine Indigenous peoples to reserves. The last federally-funded residential school, Kivalliq Hall in Rankin Inlet, closed in 1997. Schools operated in every province and territory with the exception of New Brunswick and Prince Edward Island.

The residential school system harmed Indigenous children significantly by removing them from their families, depriving them of their ancestral languages, and exposing many of them to physical and sexual abuse. Conditions in the schools led to student malnutrition, starvation, and disease. Students were also subjected to forced enfranchisement as "assimilated" citizens that removed their legal identity as Indians. Disconnected from their families and culture and forced to speak English or French, students who attended the residential school system often graduated being unable to fit into their communities but remaining subject to racist attitudes in mainstream Canadian society. The system ultimately proved successful in disrupting the transmission of Indigenous practices and beliefs across generations. The legacy of the system has been linked to an increased prevalence of post-traumatic stress, alcoholism, substance abuse, suicide, and intergenerational trauma which persist within Indigenous communities today.

Starting in the late 2000s, the Canadian government and religious communities have begun to recognize, and issue apologies for, their respective roles in the residential school system. Prime Minister Stephen Harper offered a public apology on his behalf and that of the other federal political party leaders. Nine days prior, on June 1, 2008, the Truth and Reconciliation Commission (TRC) was established to uncover the truth about the schools. The commission gathered about 7,000 statements from residential school survivors through public and private meetings at various local, regional and national events across Canada. Seven national events held between 2008 and 2013 commemorated the experience of former students of residential schools. In 2015, the TRC concluded with the establishment of the National Centre for Truth and Reconciliation and the publication of a multi-volume report detailing the testimonies of survivors and historical documents from the time. The TRC report concluded that the school system amounted to cultural genocide. Ongoing efforts since 2021 have identified thousands of probable unmarked graves on the grounds of former residential schools, though no human remains have yet to be exhumed. During a penitential pilgrimage to Canada in July 2022, Pope Francis reiterated the apologies of the Catholic Church for its role in administering many of the residential schools, also acknowledging the system as genocide. In October 2022, the House of Commons unanimously passed a motion calling on the federal Canadian government to recognize residential schools as genocide.

An antifuse is an electrical device that performs the opposite function to a fuse. Whereas a fuse starts with a low resistance and is designed to permanently break an electrically conductive path (typically when the current through the path exceeds a specified limit), an antifuse starts with a high resistance, and programming it converts it into a permanent electrically conductive path (typically when the voltage across the antifuse exceeds a certain level). This technology has many applications.
