Everywhere at the End of Time is the eleventh recording by the Caretaker, an alias of English electronic musician Leyland Kirby. Released between 2016 and 2019, its six studio albums use degrading loops of sampled ballroom music to portray the progression of Alzheimer's disease. Inspired by the success of An Empty Bliss Beyond This World (2011), Kirby produced Everywhere as his final major work under the alias. The albums were produced in Krakow and released over six-month periods to "give a sense of time passing". The album covers are abstract paintings by his friend Ivan Seal. The series drew comparisons to the works of composer William Basinski and electronic musician Burial; later stages were influenced by avant-gardist composer John Cage.

The series comprises six hours of music, portraying a range of emotions and characterised by noise throughout. Although the first three stages are similar to An Empty Bliss, the last three stages depart from Kirby's earlier ambient works. The albums reflect the patient's disorder and death, their feelings, and the phenomenon of terminal lucidity. To promote the series, Kirby partnered with anonymous visual artist Weirdcore to make music videos. At first, concerned about whether the series would seem pretentious, Kirby thought of not creating Everywhere at all; he spent more time producing it than any of his other releases. The album covers received attention from a French art exhibition named after the Caretaker's Everywhere, an Empty Bliss (2019), a compilation of archived songs.

As each stage was released, the series received increasingly positive reviews from critics; its length and dementia-driven concept led many reviewers to feel emotional about the complete edition. Considered to be Kirby's magnum opus, Everywhere was one of the most praised music releases of the 2010s. Caregivers of people with dementia also praised the albums for increasing empathy for patients among younger listeners, although some medics felt the series was too linear. It became an Internet phenomenon in the early 2020s, emerging in TikTok videos as a listening challenge, being transformed into a mod for the video game Friday Night Funkin' (2020), and appearing in internet memes.

🔗 Animal anatomy 🔗 Insects 🔗 Arthropods

The (pan)arthropod head problem is a long-standing zoological dispute concerning the segmental composition of the heads of the various arthropod groups, and how they are evolutionarily related to each other. While the dispute has historically centered on the exact make-up of the insect head, it has been widened to include other living arthropods such as chelicerates, myriapods, crustaceans; and fossil forms, such as the many arthropods known from exceptionally preserved Cambrian faunas. While the topic has classically been based on insect embryology, in recent years a great deal of developmental molecular data has become available. Dozens of more or less distinct solutions to the problem, dating back to at least 1897, have been published, including several in the 2000s.

The arthropod head problem is popularly known as the endless dispute, the title of a famous paper on the subject by Jacob G. Rempel in 1975, referring to its seemingly intractable nature. Although some progress has been made since that time, the precise nature of especially the labrum and the pre-oral region of arthropods remain highly controversial.

🔗 New York City 🔗 Architecture

75½ Bedford Street is a house located in the West Village neighborhood of New York City that is only 9 feet 6 inches (2.9 meters) wide. Built in 1873, it is often described as the narrowest house in New York. Its past tenants have included Edna St. Vincent Millay, Ann McGovern, cartoonist William Steig and anthropologist Margaret Mead. It is sometimes referred to as the Millay House, indicated by a plaque on the outside of the house. The house is located in the Greenwich Village Historic District, but is not an individually designated New York City Landmark.

🔗 Mathematics

The Banach–Tarski paradox is a theorem in set-theoretic geometry, which states the following: Given a solid ball in 3‑dimensional space, there exists a decomposition of the ball into a finite number of disjoint subsets, which can then be put back together in a different way to yield two identical copies of the original ball. Indeed, the reassembly process involves only moving the pieces around and rotating them without changing their shape. However, the pieces themselves are not "solids" in the usual sense, but infinite scatterings of points. The reconstruction can work with as few as five pieces.

A stronger form of the theorem implies that given any two "reasonable" solid objects (such as a small ball and a huge ball), the cut pieces of either one can be reassembled into the other. This is often stated informally as "a pea can be chopped up and reassembled into the Sun" and called the "pea and the Sun paradox".

The reason the Banach–Tarski theorem is called a paradox is that it contradicts basic geometric intuition. "Doubling the ball" by dividing it into parts and moving them around by rotations and translations, without any stretching, bending, or adding new points, seems to be impossible, since all these operations ought, intuitively speaking, to preserve the volume. The intuition that such operations preserve volumes is not mathematically absurd and it is even included in the formal definition of volumes. However, this is not applicable here because in this case it is impossible to define the volumes of the considered subsets. Reassembling them reproduces a volume, which happens to be different from the volume at the start.

Unlike most theorems in geometry, the proof of this result depends in a critical way on the choice of axioms for set theory. It can be proven using the axiom of choice, which allows for the construction of non-measurable sets, i.e., collections of points that do not have a volume in the ordinary sense, and whose construction requires an uncountable number of choices.

It was shown in 2005 that the pieces in the decomposition can be chosen in such a way that they can be moved continuously into place without running into one another.

🔗 Business

Founder's syndrome (also founderitis) is the difficulty faced by organizations where one or more founders maintain disproportionate power and influence following the effective initial establishment of the project, leading to a wide range of problems for the organization. The passion and charisma of the founder(s), sources of the initial creativity and productivity of the organization, become limiting or destructive factors. The syndrome occurs in both non-profit and for-profit organizations. It may simply limit further growth and success of the project, or it may lead to bitter factionalism and divisions as the scale of demands made on the organization increases, or it may result in outright failure. There are ways in which a founder or organization can respond and grow beyond this situation.

🔗 Korea

Nunchi, sometimes noonchi, is a Korean concept signifying the subtle art and ability to listen and gauge others' moods. It first appears in the 17th century as nunch'ŭi (眼勢 in Chinese characters), meaning "eye force/power". In Western culture, nunchi could be described as the concept of emotional intelligence. It is of central importance to the dynamics of interpersonal relationships. Nunchi is literally translated as "eye-measure". It is closely related to the broader concept of paralanguage, however nunchi also relies on an understanding of one's status relative to the person with whom they're interacting. It can be seen as the embodiment of skills necessary to communicate effectively in high context culture.

The concept of nunchi, and one's abundance or lack thereof, forms the basis of many common expressions and idioms. For example, a socially clumsy person can be described as nunchi eoptta (눈치 없다), meaning "absence of nunchi."

눈치 Nunchi is briefly defined as the high social sensitivity of Koreans which basically means they are able to ascertain others moods by being around them and talking to them. They are sensitive to what others say indirectly, because they want to maintain harmony. They do this by the use of the skill named "nunchi" which literally means eye measure in Korean, they sense someone's "kibun", Kibun is a Korean word which relates to mood, current feelings, and the state of mind. Facilitating nunchi, encouraging the use of this skill, is expected to result in rich understanding. It is of central importance to the dynamics of interpersonal relationships. With nunchi, Koreans are using non-verbal cues to convey emotion and meaning through various means, including voice pitch and volume as well as intonation. Nunchi also relies heavily on an understanding of one's status relative to the person with whom one is interacting. Because Korea, as with other high-context cultures caters toward in-groups that have similar experiences and expectations and from which inferences are drawn, many things are left unsaid here. The culture does the explaining, in effect. Both Kibun and Nunchi are very difficult concepts for non-Koreans to get the hang of and they will generally be forgiven for their ignorance of these concepts and consequent rude behavior, especially if they are high on the status ladder. However, one gains more than one loses by trying to understand and, as much as possible, behaving according to these rules of behavior. In Korea, personal relations frequently take precedence over business. In order to be successful, it is vital to establish good, personal relationships based on mutual trust and benefit Koreans judge this by Nunchi to get a base understanding of the individual they just met. Korean business culture is firmly grounded in respectful rapport and in order to establish this, it is essential to have the right introduction to approach the company. Koreans will use Nunchi to make sure the right approach is being used, often through a mutual friend or acquaintance at the appropriate level. Koreans spend a significant amount of time developing and fostering personal contacts. Therefore, time should be allocated for this process, particularly during the first meeting, which is frequently used to simply establish rapport and build trust.

The phrase 눈치 있다 (nunchi itda) refers to someone who's quick witted, can understand the situation quickly, or has common sense. Another way to say this is 눈치 빠르다 (nunchi ppareuda) – to have quick nunchi.

In Korean, the phrase 눈치 없다 (nunchi eoptta) refers to someone that is clueless, someone that doesn't know what's going on, or simply doesn't have any common sense basically it is the exact opposite of nunchi or when someones nunchi is lacking.

The Tunnel of Eupalinos or Eupalinian aqueduct (Greek: Ευπαλίνιον όρυγμα, romanized: Efpalinion orygma) is a tunnel of 1,036 m (3,399 ft) length running through Mount Kastro in Samos, Greece, built in the 6th century BC to serve as an aqueduct. The tunnel is the second known tunnel in history which was excavated from both ends (Ancient Greek: ἀμφίστομον, romanized: amphistomon, "having two openings"), and the first with a geometry-based approach in doing so. Today it is a popular tourist attraction.

🔗 Technology 🔗 Architecture

A Matrioshka brain is a hypothetical megastructure of immense computational capacity powered by a Dyson sphere. It was proposed in 1997 by Robert J. Bradbury (1956–2011). It is an example of a Class B stellar engine, employing the entire energy output of a star to drive computer systems. This concept derives its name from the nesting Russian Matryoshka dolls. The concept was deployed by Bradbury in the anthology Year Million: Science at the Far Edge of Knowledge.

🔗 Computing 🔗 Computer science

Ousterhout's dichotomy is computer scientist John Ousterhout's categorization that high-level programming languages tend to fall into two groups, each with distinct properties and uses: system programming languages and scripting languages – compare programming in the large and programming in the small. This distinction underlies the design of his language Tcl.

System programming languages (or applications languages) usually have the following properties:

• They are typed statically
• They support creating complex data structures
• Programs in them are compiled into machine code
• Programs in them are meant to operate largely independently of other programs

System programming languages tend to be used for components and applications with large amounts of internal functionality such as operating systems, database servers, and Web browsers. These applications typically employ complex algorithms and data structures and require high performance. Prototypical examples of system programming languages include C and Modula-2.

By contrast, scripting languages (or glue languages) tend to have the following properties:

• They are typed dynamically
• They have little or no provision for complex data structures
• Programs in them (scripts) are interpreted

Scripting languages tend to be used for applications where most of the functionality comes from other programs (often implemented in system programming languages); the scripts are used to glue together other programs or add additional layers of functionality on top of existing programs. Ousterhout claims that scripts tend to be short and are often written by less sophisticated programmers, so execution efficiency is less important than simplicity and ease of interaction with other programs. Common applications for scripting include Web page generation, report generation, graphical user interfaces, and system administration. Prototypical examples of scripting languages include AppleScript, C shell, DOS batch files, and Tcl.

The Padmanabhaswamy temple treasure is a collection of valuable objects including gold thrones, crowns, coins, statues and ornaments, diamonds and other precious stones. It was discovered in some of the subterranean vaults of the Padmanabhaswamy Temple in Thiruvananthapuram, in the Indian state of Kerala, when five of its six (or possibly eight) vaults were opened on 27 June 2011. The vaults were opened on the orders of the Supreme Court of India, which was hearing a private petition seeking transparency in the running of the temple. The discovery of the treasure attracted widespread national and international media attention as it is considered to be the largest collection of items of gold and precious stones in the recorded history of the world. On the possibility of future appropriation of the wealth, for the need of a new management and proper inventorisation of the articles in the vaults, a public interest petition was registered with Supreme court of India. In 2020, the royal family won the rights to manage the temple, as well all its financial aspects. The Supreme Court of India overruled the Kerala High Court's legal jurisprudence based on regional facts and recognition of the nullified princely agreement based on "Ruler of Travancore."
