π Bisbee Deportation
The Bisbee Deportation was the illegal kidnapping and deportation of about 1,300 striking mine workers, their supporters, and citizen bystanders by 2,000 members of a deputized posse, who arrested them beginning on July 12, 1917, in Bisbee, Arizona. The action was orchestrated by Phelps Dodge, the major mining company in the area, which provided lists of workers and others who were to be arrested to the Cochise County sheriff, Harry C. Wheeler. Those arrested were taken to a local baseball park before being loaded onto cattle cars and deported 200 miles (320Β km) to Tres Hermanas in New Mexico. The 16-hour journey was through desert without food and with little water. Once unloaded, the deportees, most without money or transportation, were warned against returning to Bisbee. The US government soon brought in members of the US Army to assist with relocating the deportees to Columbus, New Mexico.
As Phelps Dodge, in collusion with the sheriff, had closed down access to outside communications, it was some time before the story was reported. The company presented their action as reducing threats to United States interests in World War I in Europe, largely because the wartime demand for copper was heavy. The Governor of New Mexico, in consultation with President Woodrow Wilson, provided temporary housing for the deportees. A presidential mediation commission investigated the actions in November 1917, and in its final report, described the deportation as "wholly illegal and without authority in law, either State or Federal (Page 6)." Nevertheless, no individual, company, or agency was ever convicted in connection with the deportations. Arizona and Cochise County never prosecuted the case, and in United States v. Wheeler (1920), the Supreme Court ruled that the Constitution by itself does not give the federal government the power to stop kidnappings, even ones involving moving abductees across state lines on federally-regulated railroads.

π Descent of Inanna into the Underworld
The Descent of Inanna into the Underworld (or, in its Akkadian version, Descent of Ishtar into the Underworld) or Angalta ("From the Great Sky") is a Sumerian myth that narrates the descent of the goddess Inanna (Ishtar in Akkadian) into the Underworld to overthrow its ruler, her sister Ereshkigal, the "Queen of the Dead." But following the removal of her adornments, she perishes and her corpse is suspended on a nail. The god Enki intervenes indirectly, restoring Inanna to life. However, on her return journey, Inanna is required to deliver another living human in exchange for her freedom. She selects Dumuzi, her spouse, who is abruptly transported to the Underworld. In response to the pleas of Dumuzi's sister, Geshtinanna, his circumstances are somewhat ameliorated: he is permitted to remain in the Underworld for only a portion of the year, with his sister assuming his role for the remaining duration.
The myth exists in two main versions: one in Sumerian and the other in Akkadian. The Akkadian version was first discovered and translated in the 1860s. The existence of the longer and older Sumerian version was first established in the early 20th century, but it required approximately fifty years for epigraphists to fully reconstruct and translate it.
The story of Descent of Inanna into the Underworld offers insights into Mesopotamian culture through its numerous characters and developed plot. The influence of this culture on subsequent civilizations is evident in the traces of Mesopotamian elements found in Greece, Phoenicia, and the Old Testament. In the 20th century, the story was used by some psychoanalysis theorists to illustrate psychic mechanisms.

π Truchet Tiles
In information visualization and graphic design, Truchet tiles are square tiles decorated with patterns that are not rotationally symmetric. When placed in a square tiling of the plane, they can form varied patterns, and the orientation of each tile can be used to visualize information associated with the tile's position within the tiling.
Truchet tiles were first described in a 1704 memoir by SΓ©bastien Truchet entitled "MΓ©moire sur les combinaisons", and were popularized in 1987 by Cyril Stanley Smith.

π Wikipedia: Signs of AI Writing
This is a list of phrases and formatting conventions typical of AI chatbots, such as ChatGPT, with real examples taken from Wikipedia articles and drafts. Note that not all text featuring the following indicators is AI-generated; large language models, which power AI-chatbots, have been trained on human writing, and humans might happen to have a writing style similar to that of an AI. Be cautious when relying on automated artificial intelligence detection software such as GPTZero. While these services perform better than random chance, they should not replace human judgment.
Beyond simply being indicators, the following phrasings and conventions often violate Wikipedia's Manual of Style or introduce a promotional or non-neutral tone; therefore appropriate use of AI chatbots on Wikipedia should not exhibit any of these indicators.

π Purple Earth Hypothesis
The Purple Earth Hypothesis (PEH) is an astrobiological hypothesis, first proposed by molecular biologist Shiladitya DasSarma in 2007, that the earliest photosynthetic life forms of Early Earth were based on the simpler molecule retinal rather than the more complex porphyrin-based chlorophyll, making the surface biosphere appear purplish rather than its current greenish color. It is estimated to have occurred between 3.5 and 2.4 billion years ago during the Archean eon, prior to the Great Oxygenation Event and Huronian glaciation.
Retinal-containing cell membranes exhibit a single light absorption peak centered in the energy-rich green-yellow region of the visible spectrum, but transmit and reflect red and blue light, resulting in a magenta color. Chlorophyll pigments, in contrast, absorb red and blue light, but little or no green light, which results in the characteristic green reflection of plants, green algae, cyanobacteria and other organisms with chlorophyllic organelles. The simplicity of retinal pigments in comparison to the more complex chlorophyll, their association with isoprenoid lipids in the cell membrane, as well as the discovery of archaeal membrane components in ancient sediments on the Early Earth are consistent with an early appearance of life forms with purple membranes prior to the turquoise of the Canfield ocean and later green photosynthetic organisms.

π Twelve Basic Principles of Animation
Disney's twelve basic principles of animation were introduced by the Disney animators Ollie Johnston and Frank Thomas in their 1981 book The Illusion of Life: Disney Animation.[a] The principles are based on the work of Disney animators from the 1930s onwards, in their quest to produce more realistic animation. The main purpose of these principles was to produce an illusion that cartoon characters adhered to the basic laws of physics, but they also dealt with more abstract issues, such as emotional timing and character appeal.
The book has been referred to by some as the "Bible of animation", and some of its principles have been adopted by traditional studios. In 1999, The Illusion of Life was voted the "best animation book[...] of all time" in an online poll done by Animation World Network. While originally intended to apply to traditional, hand-drawn animation, the principles still have great relevance for today's more prevalent computer animation.
π Sutton SignWriting is a writing system for sign languages
Sutton SignWriting, or simply SignWriting, is a writing system for sign languages. It can be used to write any sign language, including American Sign Language, Brazilian Sign Language, Tunisian Sign Language, and many others.
SignWriting is the only international writing system for sign languages. It has been used to publish young adult fiction, translate the Bible, caption YouTube videos, and study sign language literacy.
The SignWriting system is visually iconic: its symbols depict the hands, face, and body of a signer. And unlike most writing systems, which are written linearly, the symbols of SignWriting are written two-dimensionally, to represent the signing space.
SignWriting was invented in 1974 by Valerie Sutton, a ballet dancer who eight years earlier had developed a dance notation named Sutton DanceWriting. The current standardized form of SignWriting is known as the International Sign Writing Alphabet (ISWA).

π Houdini of FL: autistic savant sentenced for taking tools he inherited
Mark DeFriest (born August 18, 1960), known as the Houdini of Florida, is an American man known for his repeated escapes from prison, having successfully done so 7 times. Born in rural Florida, he was arrested for the first time in 1978, serving for a year. In 1980, DeFriest was sentenced to four years in prison for violating probation via illegal firearms possession, having initially been arrested for retrieving work tools that his recently deceased father had willed him before the will had completed probate. His sentence has since been repeatedly extended for having attempted to escape 13 times (including one count of armed robbery during one attempt), as well as collecting hundreds of disciplinary reports for minor infractions, leading to a cumulative stay of 34 years in prison.
DeFriest has cumulatively spent 27 years in solitary confinement. Following publicity, DeFriest was granted parole and released on 5 February 2019. Ten days later, he was rearrested as he checked into a mental health facility.

π Hygiene Hypothesis
In medicine, the hygiene hypothesis states that early childhood exposure to particular microorganisms (such as the gut flora and helminth parasites) protects against allergies by properly tuning the immune system. In particular, a lack of such exposure is thought to lead to poor immune tolerance. The time period for exposure begins before birth and ends at school age.
While early versions of the hypothesis referred to microorganism exposure in general, later versions apply to a specific set of microbes that have co-evolved with humans. The updates have been given various names, including the microbiome depletion hypothesis, the microflora hypothesis, and the "old friends" hypothesis. There is a significant amount of evidence supporting the idea that lack of exposure to these microbes is linked to allergies or other conditions, although it is still rejected by many scientists.
The term "hygiene hypothesis" has been described as a misnomer because people incorrectly interpret it as referring to their own cleanliness. Having worse personal hygiene, such as not washing hands before eating, only increases the risk of infection without affecting the risk of allergies or immune disorders. Hygiene is essential for protecting vulnerable populations such as the elderly from infections, preventing the spread of antibiotic resistance, and combating emerging infectious diseases such as Ebola. The hygiene hypothesis does not suggest that having more infections during childhood would be an overall benefit.
