Parrondo's paradox, a paradox in game theory, has been described as: A combination of losing strategies becomes a winning strategy. It is named after its creator, Juan Parrondo, who discovered the paradox in 1996. A more explanatory description is:

There exist pairs of games, each with a higher probability of losing than winning, for which it is possible to construct a winning strategy by playing the games alternately.

Parrondo devised the paradox in connection with his analysis of the Brownian ratchet, a thought experiment about a machine that can purportedly extract energy from random heat motions popularized by physicist Richard Feynman. However, the paradox disappears when rigorously analyzed. Winning strategies consisting of a combinations of losing strategies have been explored in biology before Parrondo's paradox was published. More recently, problems in evolutionary biology and ecology have been modeled and explained in terms of the paradox.

Rhythm 0 was a six-hour work of performance art by Serbian artist Marina Abramović in Naples in 1974. The work involved Abramović standing still while the audience was invited to do to her whatever they wished, using one of 72 objects she had placed on a table. These included a rose, feather, perfume, honey, bread, grapes, wine, scissors, a scalpel, nails, a metal bar, a gun, and a bullet.

There were no separate stages. Abramović and the visitors stood in the same space, making it clear that the latter were part of the work. The purpose of the piece, she said, was to find out how far the public would go: "What is the public about and what are they going to do in this kind of situation?"

ISO 3103 is a standard published by the International Organization for Standardization (commonly referred to as ISO), specifying a standardized method for brewing tea, possibly sampled by the standardized methods described in ISO 1839. It was originally laid down in 1980 as BS 6008:1980 by the British Standards Institution, and a revision was published in December, 2019 as ISO/NP 3103. It was produced by ISO Technical Committee 34 (Food products), Sub-Committee 8 (Tea).

The abstract states the following:

The method consists in extracting of soluble substances in dried tea leaf, contained in a porcelain or earthenware pot, by means of freshly boiling water, pouring of the liquor into a white porcelain or earthenware bowl, examination of the organoleptic properties of the infused leaf, and of the liquor with or without milk, or both.

This standard is not meant to define the proper method for brewing tea intended for general consumption, but rather to document a tea brewing procedure where meaningful sensory comparisons can be made. An example of such a test would be a taste-test to establish which blend of teas to choose for a particular brand or basic label in order to maintain a consistent tasting brewed drink from harvest to harvest.

The work was the winner of the parodic Ig Nobel Prize for Literature in 1999.

In pipeline transportation, pigging is the practice of using devices known as pigs or scrapers to perform various maintenance operations. This is done without stopping the flow of the product in the pipeline. These devices are known as pigs because they scrape or clean just like a normal pig.

These operations include but are not limited to cleaning and inspecting the pipeline. This is accomplished by inserting the pig into a "pig launcher" (or "launching station") — an oversized section in the pipeline, reducing to the normal diameter. The launching station is then closed and the pressure-driven flow of the product in the pipeline is used to push the pig along down the pipe until it reaches the receiving trap — the "pig catcher" (or "receiving station").

Shit life syndrome (SLS) is a phrase used by physicians in the United Kingdom and the United States for the effect that a variety of poverty or abuse-induced disorders can have on patients.

Sarah O'Connor's 2018 article for the Financial Times "Left behind: can anyone save the towns the economy forgot?" on shit life syndrome in the English coastal town of Blackpool won the 2018 Orwell Prize for Exposing Britain's Social Evils. O'Connor wrote that

Blackpool exports healthy skilled people and imports the unskilled, the unemployed and the unwell. As people overlooked by the modern economy wash up in a place that has also been left behind, the result is a quietly unfolding health crisis. More than a tenth of the town's working-age inhabitants live on state benefits paid to those deemed too sick to work. Antidepressant prescription rates are among the highest in the country. Life expectancy, already the lowest in England, has recently started to fall. Doctors in places such as this have a private diagnosis for what ails some of their patients: "Shit Life Syndrome" ... People with SLS really do have mental or physical health problems, doctors say. But they believe the causes are a tangled mix of economic, social and emotional problems that they — with 10- to 15-minute slots per patient — feel powerless to fix. The relationship between economics and health is blurry, complex and politically fraught. But it is too important to ignore.

In a column for The Irish Times, writer John McManus questioned whether Ireland had developed shit life syndrome in the wake of a recent fall in life expectancy.

A 2018 article in The Quietus on the films of the British director Mike Leigh identified shit life syndrome in Leigh's 2002 film All or Nothing. Kinney wrote that "The film asks questions about poverty – what does poverty do to people? How do you react when the chips are down? ... The rise of populism in this country has been analysed through the lens of the 'left behind' – in a less crude way, this is exactly what All or Nothing was observing sixteen years ago."

Rosemary Rizq, in an essay in the 2016 collection The Future of Psychological Therapy, questioned the origin of the term shit life syndrome, writing that "The phrase seemed to denote a level of long-standing poverty, family breakdown, lack of stability, unemployment and potential risk factors common to many of the predominately young, working class patients referred to the [psychotherapeutic] service" for shit is "something that we continually reject, get rid of or hide. At the same time it is something we cannot completely repudiate, it is part of us, something we need" and that the individuals with SLS have problems so "terrible, so untouchable" that they "quite literally cannot be thought about, cannot be handled by the service", yet a therapeutic organisation is "obliged to do so".

Bat bombs were an experimental World War II weapon developed by the United States. The bomb consisted of a bomb-shaped casing with over a thousand compartments, each containing a hibernating Mexican free-tailed bat with a small, timed incendiary bomb attached. Dropped from a bomber at dawn, the casings would deploy a parachute in mid-flight and open to release the bats, which would then disperse and roost in eaves and attics in a 20–40-mile radius (32–64 km). The incendiaries, which were set on timers, would then ignite and start fires in inaccessible places in the largely wood and paper constructions of the Japanese cities that were the weapon's intended target.

The Basque–Icelandic pidgin was a Basque-based pidgin spoken in Iceland in the 17th century. It consisted of Basque, Germanic and Romance words.

Basque whale hunters who sailed to the Icelandic Westfjords used the pidgin as a means of rudimentary communication with locals. It might have developed in Westfjords, where manuscripts were written in the language, but since it had influences from many other European languages, it is more likely that it was created elsewhere and brought to Iceland by Basque sailors. Basque entries are mixed with words from Dutch, English, French, German and Spanish. The Basque–Icelandic pidgin is thereby not a mixture between Basque and Icelandic, but between Basque and other languages. It was named from the fact that it was written down in Iceland and translated into Icelandic.

Only a few manuscripts have been found containing Basque–Icelandic glossary, and knowledge about the pidgin is limited.

The Great Stirrup Controversy is the academic debate about the Stirrup Thesis, the theory that feudalism in Europe developed largely as a result of the introduction of the stirrup to cavalry in the 8th century CE. It relates to the hypothesis suggested by Lynn Townsend White Jr. in his 1962 book, Medieval Technology and Social Change. White believed that the stirrup enabled heavy cavalry and shock combat, which in turn prompted the Carolingian dynasty of the 8th and 9th centuries to organize its territory into a vassalage system, rewarding mounted warriors with land grants for their service. White's book has proved very influential, but others have accused him of speculation, oversimplification, and ignoring contradictory evidence on the subject. Scholars have debated whether the stirrup actually provided the impetus for this social change, or whether the rise of heavy cavalry resulted from political changes in Medieval Europe.
