🔗 Mathematics

In mathematics, the Kolakoski sequence, sometimes also known as the Oldenburger–Kolakoski sequence, is an infinite sequence of symbols {1,2} that is the sequence of run lengths in its own run-length encoding. It is named after the recreational mathematician William Kolakoski (1944–97) who described it in 1965, but it was previously discussed by Rufus Oldenburger in 1939.

🔗 Metalworking

Muntz metal (also known as yellow metal) is an alpha-beta brass alloy composed of approximately 60% copper, 40% zinc and a trace of iron. It is named after George Fredrick Muntz, a metal-roller of Birmingham, England, who commercialised the alloy following his patent of 1832.

The alloy must be worked hot and is used today for corrosion-resistant machine parts. Alpha-beta (also called duplex) metals contain both the α and β phases. The α phase refers to a crystal structure that is face-centered cubic, while the β phase is body-centered cubic.

Its original application was as a replacement for copper sheathing on the bottom of boats, as it maintained the anti-fouling abilities of the pure copper at around two thirds of the price. It became the material of choice for this application and Muntz made his fortune. It was found that copper prevented any organism that attempted to attach itself to a hull sheathed in the metal. Thus, it was also used to sheathe the piles of piers in tropical seas, as a protection against teredo shipworms, and in locomotive tubes. After successful experimentation with the sheathing Muntz also took out a patent for bolts of the same composition. These too proved a success as they not only were cheaper but also very strong and lasted longer. A notable use of Muntz metal was in the hull of the Cutty Sark.

In shopping mall design, the Gruen transfer (also known as the Gruen effect) is the moment when consumers enter a shopping mall or store and, surrounded by an intentionally confusing layout, lose track of their original intentions, making consumers more susceptible to make impulse buys. It is named for Austrian architect Victor Gruen, who disavowed such manipulative techniques.

🔗 Mathematics

A hinged dissection, also known as a swing-hinged dissection or Dudeney dissection, is a kind of geometric dissection in which all of the pieces are connected into a chain by "hinged" points, such that the rearrangement from one figure to another can be carried out by swinging the chain continuously, without severing any of the connections. Typically, it is assumed that the pieces are allowed to overlap in the folding and unfolding process; this is sometimes called the "wobbly-hinged" model of hinged dissection.

🔗 History 🔗 Ancient Near East 🔗 Malta 🔗 Phoenicia

The Cippi of Melqart are a pair of Phoenician marble cippi that were unearthed in Malta under undocumented circumstances and dated to the 2nd century BC. These are votive offerings to the god Melqart, and are inscribed in two languages, Ancient Greek and Phoenician, and in the two corresponding scripts, the Greek and the Phoenician alphabet. They were discovered in the late 17th century, and the identification of their inscription in a letter dated 1694 made them the first Phoenician writing to be identified and published in modern times. Because they present essentially the same text (with some minor differences), the cippi provided the key to the modern understanding of the Phoenician language. In 1758, the French scholar Jean-Jacques Barthélémy relied on their inscription, which used 17 of the 22 letters of the Phoenician alphabet, to decipher the unknown language.

The tradition that the cippi were found in Marsaxlokk was only inferred by their dedication to Heracles, whose temple in Malta had long been identified with the remains at Tas-Silġ. The Grand Master of the Order of the Knights Hospitaller, Fra Emmanuel de Rohan-Polduc, presented one of the cippi to the Académie des Inscriptions et Belles-Lettres in 1782. This cippus is currently in the Louvre Museum in Paris, while the other rests in the National Museum of Archaeology in Valletta, Malta. The inscription is known as KAI 47.

The Big Mac Index is a price index published by The Economist as an informal way of measuring the purchasing power parity (PPP) between two currencies and provides a test of the extent to which market exchange rates result in goods costing the same in different countries. It "seeks to make exchange-rate theory a bit more digestible."

The index, created in 1986, takes its name from the Big Mac, a hamburger sold at McDonald's restaurants.

🔗 Philosophy

The Tinkerbell effect is an American English expression describing things that are thought to exist only because people believe in them. The effect is named after Tinker Bell, the fairy in the play Peter Pan, who is revived from near death by the belief of the audience.

Another form is called the Reverse Tinkerbell effect, a term coined by David Post in 2003. It stipulates that the more you believe in something the more likely it is to vanish. For example, as more people believe that driving is safe, more people will drive carelessly, in turn making driving less safe.

Loulan, also called Krorän or Kroraina (simplified Chinese: 楼兰; traditional Chinese: 樓蘭; pinyin: Lóulán; Uyghur: كروران, Кроран‎, ULY: Kroran) was an ancient kingdom based around an important oasis city along the Silk Road already known in the 2nd century BCE on the northeastern edge of the Lop Desert. The term Loulan is the Chinese transcription of the native name Krorän and is used to refer to the city near Lop Nur as well as the kingdom.

The kingdom was renamed Shanshan (鄯善) after its king was assassinated by an envoy of the Han dynasty in 77 BCE; however, the town at the northwestern corner of the brackish desert lake Lop Nur retained the name of Loulan. The kingdom included at various times settlements such as Niya, Charklik, Miran, and Qiemo. It was intermittently under Chinese control from the early Han dynasty onward until its abandonment centuries later. The ruins of Loulan are near the now-desiccated Lop Nur in the Bayingolin Mongol Autonomous Prefecture, Xinjiang, and they are now completely surrounded by desert.

Jerry Eugene Pournelle (; August 7, 1933 – September 8, 2017) was an American polymath: scientist in the area of operations research and human factors research, science fiction writer, essayist, journalist, and one of the first bloggers. In the 1960s and early 1970s, he worked in the aerospace industry, but eventually focused on his writing career. In an obituary in gizmodo, he is described as "a tireless ambassador for the future."

Pournelle is particularly known for writing hard science fiction, and received multiple awards for his writing. In addition to his solo writing, he wrote several novels with collaborators, most notably Larry Niven. Pournelle served a term as President of the Science Fiction and Fantasy Writers of America.

Pournelle's journalism focused primarily on the computer industry, astronomy, and space exploration. From the 1970s until the early 1990s, he contributed to the computer magazine Byte, writing from the viewpoint of an intelligent user, with the oft-cited credo, “We do this stuff so you won’t have to.” He created one of the first blogs, entitled "Chaos Manor", which included commentary about politics, computer technology, space technology, and science fiction.

Pournelle was also known for his paleoconservative political views, which were sometimes expressed in his fiction. He was one of the founders of the Citizens' Advisory Council on National Space Policy, which developed some of the Reagan Administration's space initiatives, including the earliest versions of what would become the Strategic Defense Initiative.

On the morning of January 31, 2007, the Boston Police Department and the Boston Fire Department mistakenly identified battery-powered LED placards depicting the Mooninites, characters from the Adult Swim animated television series Aqua Teen Hunger Force, as improvised explosive devices (IEDs), leading to a massive panic. Placed throughout Boston, Massachusetts, and the surrounding cities of Cambridge and Somerville by Peter "Zebbler" Berdovsky and Sean Stevens, these devices were part of a nationwide guerrilla marketing advertising campaign for Aqua Teen Hunger Force Colon Movie Film for Theaters.

The massive panic led to controversy and criticism from U.S. media sources, including The Boston Globe, Los Angeles Times, Fox News, The San Francisco Chronicle, The New York Times, CNN, and The Boston Herald. Some ridiculed the city's response to the devices—including the arrests of the two men hired to place the placards around the area—as disproportionate and indicative of a generation gap between city officials and the younger residents of Boston, at whom the ads were targeted. Several sources noted that the hundreds of officers in the Boston police department or city emergency planning office on scene were unable to identify the figure depicted for several hours until a young staffer at Mayor Thomas Menino's office saw the media coverage and recognized the figures.

After the devices were removed, the Boston Police Department stated in its defense that the ad devices shared some similarities with improvised explosive devices, with them also discovering an identifiable power source, a circuit board with exposed wiring, and electrical tape. Investigators were not mollified by the discovery that the devices were not explosive in nature, stating they still intended to determine "if this event was a hoax or something else entirely". Although city prosecutors eventually concluded there was no ill intent involved in the placing of the ads, the city continues to refer to the event as a "bomb hoax" (implying intent) rather than a "bomb scare".

Reflecting years later, various academics and media sources have characterized the phenomenon as a form of social panic. Gregory Bergman wrote in his 2008 book BizzWords that the devices were basically a self-made form of the children's toy Lite-Brite. Bruce Schneier wrote in his 2009 book Schneier on Security that Boston officials were "ridiculed" for their overreaction to the incident. In his 2009 book Secret Agents, historian and communication professor Jeremy Packer discussed a cultural phenomenon called the "panic discourse" and described the incident as a "spectacular instance of this panic". In a 2012 article, The Boston Phoenix called the incident the "Great Mooninite Panic of 2007". A 2013 publication by WGBH wrote that the majority of Boston youth thought that the arrests of two men who placed devices were not justified.
