Magnetocapacitance is a property of some dielectric, insulating materials, and metal–insulator–metal heterostructures that exhibit a change in the value of their capacitance when an external magnetic field is applied to them. Magnetocapacitance can be an intrinsic property of some dielectric materials, such as multiferroic compounds like BiMnO₃, or can be a manifest of properties extrinsic to the dielectric but present in capacitance structures like Pd, Al₂O₃, and Al.

The Trojan Room coffee pot was a coffee machine located in the Computer Laboratory of the University of Cambridge, England. Created in 1991 by Quentin Stafford-Fraser and Paul Jardetzky, it was migrated from their laboratory network to the web in 1993 becoming the world's first webcam.

To save people working in the building the disappointment of finding the coffee machine empty after making the trip to the room, a camera was set up providing a live picture of the coffee pot to all desktop computers on the office network. After the camera was connected to the Internet a few years later, the coffee pot gained international renown as a feature of the fledgling World Wide Web, until being retired in 2001.

Faxlore is a sort of folklore: humorous texts, folk poetry, folk art, and urban legends that are circulated, not by word of mouth, but by fax machine. Xeroxlore or photocopylore is similar material circulated by photocopying; compare samizdat in Soviet-bloc countries.

The first use of the term xeroxlore was in Michael J. Preston's essay "Xerox-lore", 1974. "Photocopylore" is perhaps the most frequently encountered name for the phenomenon now, because of trademark concerns involving the Xerox Corporation. The first use of this term came in A Dictionary of English Folklore by Jacqueline Simpson and Steve Roud.

Bellman's lost-in-a-forest problem is an unsolved minimization problem in geometry, originating in 1955 by the American applied mathematician Richard E. Bellman. The problem is often stated as follows: "A hiker is lost in a forest whose shape and dimensions are precisely known to him. What is the best path for him to follow to escape from the forest?" It is usually assumed that the hiker does not know the starting point or direction he is facing. The best path is taken to be the one that minimizes the worst-case distance to travel before reaching the edge of the forest. Other variations of the problem have been studied.

A proven solution is only known for a few shapes or classes of shape. A general solution would be in the form of a geometric algorithm which takes the shape of the forest as input and returns the optimal escape path as the output. Although real world applications are not apparent, the problem falls into a class of geometric optimization problems including search strategies that are of practical importance. A bigger motivation for study has been the connection to Moser's worm problem. It was included in a list of 12 problems described by the mathematician Scott W. Williams as "million buck problems" because he believed that the techniques involved in their resolution will be worth at least a million dollars to mathematics.

Wolf warrior diplomacy (Chinese: 战狼外交; pinyin: Zhànláng Wàijiāo) describes an aggressive style of coercive diplomacy adopted by Chinese diplomats in the 21st century under Chinese leader Xi Jinping's administration. The term was coined from the Chinese action film, Wolf Warrior 2. This approach is in contrast to prior Chinese diplomatic practices of Deng Xiaoping, which had emphasized the avoidance of controversy and the use of cooperative rhetoric. Wolf warrior diplomacy is confrontational and combative, with its proponents loudly denouncing any criticism of China on social media and in interviews. As an attempt to gain "discourse power" in international politics, wolf warrior diplomacy forms one part of a new foreign policy strategy called Xi Jinping's "Major Country Diplomacy" (Chinese: 大国外交; pinyin: Dàguó Wàijiāo) which has legitimized a more active role for China on the world stage, including engaging in an open ideological struggle with the West.

Although the phrase "wolf warrior diplomacy" was popularized as a description of this diplomatic approach during the COVID-19 pandemic, the appearance of wolf warrior-style diplomats had begun a few years prior. Chinese leader and General Secretary of the Chinese Communist Party Xi Jinping's foreign policy writ large, perceived anti-China hostility from the West among Chinese government officials, and shifts within the Chinese diplomatic bureaucracy have been cited as factors leading to its emergence.

This is a list of musical compositions or pieces of music that have unusual time signatures. "Unusual" is here defined to be any time signature other than simple time signatures with top numerals of 2, 3, or 4 and bottom numerals of 2, 4, or 8, and compound time signatures with top numerals of 6, 9, or 12 and bottom numerals 4, 8, or 16.

The conventions of musical notation typically allow for more than one written representation of a particular piece. The chosen time signature largely depends upon musical context, personal taste of the composer or transcriber, and the graphic layout on the written page. Frequently, published editions were written in a specific time signature to visually signify the tempo for slow movements in symphonies, sonatas, and concerti.

A perfectly consistent unusual metrical pattern may be notated in a more familiar time signature that does not correspond to it. For example, the Passacaglia from Britten's opera Peter Grimes consists of variations over a recurring bass line eleven beats in length but is notated in ordinary ⁴
₄ time, with each variation lasting 2+3⁄4 bars, and therefore commencing each time one crotchet earlier in the bar than the preceding one.

Xennials or xennials (also known as the Oregon Trail Generation and Generation Catalano) are the micro-generation of people on the cusp of the Generation X and Millennial demographic cohorts. Researchers and popular media use birth years from the late 1970s to the early 1980s. Xennials are described as having had an analog childhood and a digital young adulthood.

In 2020, xennial was included in the Oxford Dictionary of English.

In the philosophy of mathematics, intuitionism, or neointuitionism (opposed to preintuitionism), is an approach where mathematics is considered to be purely the result of the constructive mental activity of humans rather than the discovery of fundamental principles claimed to exist in an objective reality. That is, logic and mathematics are not considered analytic activities wherein deep properties of objective reality are revealed and applied, but are instead considered the application of internally consistent methods used to realize more complex mental constructs, regardless of their possible independent existence in an objective reality.

The X17 particle is a hypothetical subatomic particle proposed by Attila Krasznahorkay and his colleagues to explain certain anomalous measurement results. The particle has been proposed to explain wide angles observed in the trajectory paths of particles produced during a nuclear transition of beryllium-8 atoms and in stable helium atoms. The X17 particle could be the force carrier for a postulated fifth force, possibly connected with dark matter, and has been described as a protophobic (i.e., ignoring protons) X boson with a mass near 17 MeV.

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.
