In legal parlance, a peppercorn is a metaphor for a very small cash payment or other nominal consideration, used to satisfy the requirements for the creation of a legal contract. It is featured in Chappell & Co Ltd v Nestle Co Ltd ([1960] AC 87), which stated that "a peppercorn does not cease to be good consideration if it is established that the promisee does not like pepper and will throw away the corn". However, the cited passage is mere dicta, and not the basis for the decision.

Proofs from THE BOOK is a book of mathematical proofs by Martin Aigner and Günter M. Ziegler. The book is dedicated to the mathematician Paul Erdős, who often referred to "The Book" in which God keeps the most elegant proof of each mathematical theorem. During a lecture in 1985, Erdős said, "You don't have to believe in God, but you should believe in The Book."

The War Powers Resolution (also known as the War Powers Resolution of 1973 or the War Powers Act) (50 U.S.C. ch. 33) is a federal law intended to check the U.S. president's power to commit the United States to an armed conflict without the consent of the U.S. Congress. The resolution was adopted in the form of a United States congressional joint resolution. It provides that the president can send the U.S. Armed Forces into action abroad only by declaration of war by Congress, "statutory authorization", or in case of "a national emergency created by attack upon the United States, its territories or possessions, or its armed forces".

The bill was introduced by Clement Zablocki, a Democratic congressman representing Wisconsin's 4th district. The bill had bipartisan support and was co-sponsored by a number of U.S. military veterans. The War Powers Resolution requires the president to notify Congress within 48 hours of committing armed forces to military action and forbids armed forces from remaining for more than 60 days, with a further 30-day withdrawal period, without congressional authorization for use of military force (AUMF) or a declaration of war by the United States. The resolution was passed by two-thirds each of the House and Senate, overriding the veto of President Richard Nixon.

It has been alleged that the War Powers Resolution has been violated in the past. However, Congress has disapproved all such incidents, and no allegations have resulted in successful legal actions taken against a president.

SHRDLU was an early natural language understanding computer program, developed by Terry Winograd at MIT in 1968–1970. In it, the user carries on a conversation with the computer, moving objects, naming collections and querying the state of a simplified "blocks world", essentially a virtual box filled with different blocks.

SHRDLU was written in the Micro Planner and Lisp programming language on the DEC PDP-6 computer and a DEC graphics terminal. Later additions were made at the computer graphics labs at the University of Utah, adding a full 3D rendering of SHRDLU's "world".

The name SHRDLU was derived from ETAOIN SHRDLU, the arrangement of the letter keys on a Linotype machine, arranged in descending order of usage frequency in English.

The Sea Organization (also known as the Sea Org) is a Scientology organization, which the Church of Scientology describes as a "fraternal religious order, comprising the church's most dedicated members". All Scientology management organizations are controlled exclusively by members of the Sea Org. David Miscavige, the de facto leader of Scientology, is the highest-ranking Sea Org officer, holding the rank of captain.

The Sea Org has been described as a paramilitary organization and as a private naval force, having operated several vessels in its past and displaying a maritime tradition. Some ex-members and scholars have described the Sea Org as a totalitarian organization marked by intensive surveillance and a lack of freedom. The Sea Org has also been compared to a monastic organization.

In a 1992 memorandum by the Church of Scientology International, the following information was provided to the Internal Revenue Service with regards to nature of the Sea Org:

[the Sea Org] does not have an ecclesiastical organizing board or command channels chart or secular existence such as an incorporated or unincorporated association. ... Although there is no such "organization" as the Sea Organization, the term Sea Org has a colloquial usage which implies that there is. There are general recruitment posters and literature for "The Sea Org" which implies that people will be employed by the Sea Org when in reality they will join, making the billion year commitment, at some church that is staffed by Sea Org members and become employees of that church corporation. ... The Sea Org exists as a spiritual commitment that is factually beyond the full understanding of the Service or any other but a trained and audited Scientologist.

The Sea Org was established on August 12, 1967, by L. Ron Hubbard, the founder of Dianetics and Scientology, initially on board three ships, the Diana, the Athena, and the Apollo, with the latter serving as flagship.

In 1971, the Sea Org assumed responsibility for the church's ecclesiastical development, and in particular the delivery of the upper levels of its auditing and training, known as the Operating Thetan or "OT" levels. In 1981, under the aegis of the Commodore's Messenger Organization led by David Miscavige, the Sea Org dissolved the Guardian's Office (GO) and assumed full responsibility for the church's international management, later reassigning the GO's duties to the Office of Special Affairs in 1983 during the corporate restructuring of the Church.

It moved to land-based organizations in 1975, though maritime customs persist, with many members wearing naval-style uniforms and addressing both male and female officers as "sir." In 1985, the church purchased a 440-foot (130 m) motor vessel, the Freewinds, which docks in Curaçao in the southern Caribbean and is used as a religious retreat and training center, staffed entirely by Sea Org members. Sea Org members make a lifetime commitment to Scientology by signing a billion-year contract officially described as a symbolic pledge. In exchange, members are given free room and board, as well as a small weekly allowance. Sea Org members agree to strict codes of discipline, such as disavowing premarital sex, working long hours (on average at least 100 hours per week) and living in communal housing called "berthings." They are allowed to marry, but must relinquish their membership if they have or want to raise children.

The East German balloon escape occurred on 16 September 1979, when eight people in two families escaped the Eastern Bloc country of East Germany by crossing the border to the Western Bloc's West Germany in a homemade hot air balloon at around 2:00 a.m. The escape plot was carried out over one and a half years, including a previously unsuccessful attempt, three different balloons, and various modifications. One failed crossing alerted the government to the plot, but the police were not able to identify the suspects before their flight to the West.

A mellified man, or a human mummy confection, was a legendary medicinal substance created by steeping a human cadaver in honey. The concoction is detailed in Chinese medical sources, most significantly the Bencao Gangmu of the 16th-century Chinese medical doctor and pharmacologist Li Shizhen. Relying on a second-hand account, Li reports a story that some elderly men in Arabia, nearing the end of their lives, would submit themselves to a process of mummification in honey to create a healing confection.

This process differed from a simple body donation because of the aspect of self-sacrifice; the mellification process would ideally start before death. The donor would stop eating any food other than honey, going as far as to bathe in the substance. Shortly, his feces (and even his sweat, according to legend) would consist of honey. When this diet finally proved fatal, the donor's body would be placed in a stone coffin filled with honey.

After a century or so, the contents would have turned into a sort of confection reputedly capable of healing broken limbs and other ailments. This confection would then be sold in street markets as a hard to find item with a hefty price.

Basic income, also called universal basic income (UBI), citizen's income, citizen's basic income in the United Kingdom, basic income guarantee in the United States and Canada, or basic living stipend or guaranteed annual income or universal demogrant, is a governmental public program for a periodic payment delivered to all on an individual basis without means test or work requirement. The incomes would be:

• Unconditional: A basic income would vary with age, but with no other conditions. Everyone of the same age would receive the same basic income, whatever their gender, employment status, family structure, contribution to society, housing costs, or anything else.
• Automatic: Someone's basic income would be automatically paid weekly or monthly into a bank account or similar.
• Non-withdrawable: Basic incomes would not be means-tested. Whether someone's earnings increase, decrease, or stay the same, their basic income will not change.
• Individual: Basic incomes would be paid on an individual basis and not on the basis of a couple or household.
• As a right: Every legal resident would receive a basic income, subject to a minimum period of legal residency and continuing residency for most of the year.

Basic income can be implemented nationally, regionally or locally. An unconditional income that is sufficient to meet a person's basic needs (at or above the poverty line) is sometimes called a full basic income while if it is less than that amount, it is sometimes called partial. A welfare system with some characteristics similar to those of a basic income is a negative income tax in which the government stipend is gradually reduced with higher labour income. Some welfare systems are sometimes regarded as steps on the way to a basic income, but because they have conditionalities attached they are not basic incomes. If they raise household incomes to specified minima they are called guaranteed minimum income systems. For example, Bolsa Família in Brazil is restricted to poor families and the children are obligated to attend school.

Several political discussions are related to the basic income debate. Examples include the debates regarding robotization, artificial intelligence (AI), and the future of work. A key issue in these debates is whether robotisation and AI will significantly reduce the number of available jobs. Basic income often comes up as a proposal in these discussions.

The Karnaugh map (KM or K-map) is a method of simplifying Boolean algebra expressions. Maurice Karnaugh introduced it in 1953 as a refinement of Edward Veitch's 1952 Veitch chart, which actually was a rediscovery of Allan Marquand's 1881 logical diagram aka Marquand diagram but with a focus now set on its utility for switching circuits. Veitch charts are therefore also known as Marquand–Veitch diagrams, and Karnaugh maps as Karnaugh–Veitch maps (KV maps).

The Karnaugh map reduces the need for extensive calculations by taking advantage of humans' pattern-recognition capability. It also permits the rapid identification and elimination of potential race conditions.

The required Boolean results are transferred from a truth table onto a two-dimensional grid where, in Karnaugh maps, the cells are ordered in Gray code, and each cell position represents one combination of input conditions, while each cell value represents the corresponding output value. Optimal groups of 1s or 0s are identified, which represent the terms of a canonical form of the logic in the original truth table. These terms can be used to write a minimal Boolean expression representing the required logic.

Karnaugh maps are used to simplify real-world logic requirements so that they can be implemented using a minimum number of physical logic gates. A sum-of-products expression can always be implemented using AND gates feeding into an OR gate, and a product-of-sums expression leads to OR gates feeding an AND gate. Karnaugh maps can also be used to simplify logic expressions in software design. Boolean conditions, as used for example in conditional statements, can get very complicated, which makes the code difficult to read and to maintain. Once minimised, canonical sum-of-products and product-of-sums expressions can be implemented directly using AND and OR logic operators. Diagrammatic and mechanical methods for minimizing simple logic expressions have existed since at least the medieval times. More systematic methods for minimizing complex expressions began to be developed in the early 1950s, but until the mid to late 1980s the Karnaugh map was the most common used in practice.

The Ambassadors (1533) is a painting by Hans Holbein the Younger. Also known as Jean de Dinteville and Georges de Selve, it was created in the Tudor period, in the same year Elizabeth I was born. As well as being a double portrait, the painting contains a still life of several meticulously rendered objects, the meaning of which is the cause of much debate. It also incorporates a much-cited example of anamorphosis in painting. It is part of the collection at the National Gallery in London.
