π Small-World Experiment
The small-world experiment comprised several experiments conducted by Stanley Milgram and other researchers examining the average path length for social networks of people in the United States. The research was groundbreaking in that it suggested that human society is a small-world-type network characterized by short path-lengths. The experiments are often associated with the phrase "six degrees of separation", although Milgram did not use this term himself.

π Inductive Reasoning Aptitude
Inductive reasoning aptitude (also called differentiation or inductive learning ability) measures how well a person can identify a pattern within a large amount of data. It involves applying the rules of logic when inferring general principles from a constellation of particulars.
Measurement is generally done in a timed test by showing four pictures or words and asking the test taker to identify which of the pictures or words does not belong in the set. The test taker is shown a large number of sets of various degrees of difficulty. The measurement is made by timing how many of these a person can properly identify in a set period of time. The test resembles the game 'Which of These Is Not Like the Others'.
Inductive reasoning is very useful for scientists, auto mechanics, system integrators, lawyers, network engineers, medical doctors, system administrators and members of all fields where substantial diagnostic or data interpretation work is needed. Inductive reasoning aptitude is also useful for learning a graphical user interface quickly, because highly inductive people are very good at seeing others' categorization schemes. Inductive reasoning aptitude is often counter-productive in fields like sales where tolerance is very important, because highly inductive people tend to be good at seeing faults in others.

π Star Trek Continues
Star Trek Continues is an American fan-made web series set in the Star Trek universe. Produced by the nonprofit charity Trek Continues, Inc. and Dracogen, and initially co-produced by Far from Home LLC and Farragut Films, the series consists of 11 episodes released between 2013 and 2017. The series is an unofficial direct continuation of Star Trek: The Original Series, and emulates its visual and storytelling features to achieve the same look and feel. Those who made the show have said in interviews that the intent was to finish the original five-year mission of the show, and this is borne out in the plot lines of the final two episodes.
The series was fan-created and all episodes were released to watch on YouTube. As with all such Star Trek fan productions, use of copyrighted and trademarked properties from the original series was allowed so long as the production was not commercial. A portion of the funds necessary to produce the episodes was raised through successful Kickstarter and Indiegogo campaigns, to which thousands of backers contributed.
Star Trek Continues won a Webby Award for "People's Choice β Long Form Drama" in 2016, a Geekie Award for "Best Web Series" in 2014, and numerous Telly and Accolade awards. The series was very positively received by critics, who praised the quality of the production and stated that the show set a new standard for Star Trek fan films.
After the 11th episode was released in late 2017, the Star Trek Continues series ended.
π Neijuan
Neijuan, sometimes known by the English term involution, is a Chinese term that describes a condition in which a system, institution, or competitive process continues to intensify in effort, complexity, or participation without a corresponding increase in output, efficiency, or collective benefit. Neijuan is the Chinese calque of the English word involution. Neijuan is written with two characters which mean 'inside' and 'curling/rolling'.
Neijuan had been used to describe an uneven distribution of social, economic, and educational resources and ongoing economic malaise, especially in terms of higher education bodies and labor markets. On a macroeconomic level, neijuan has led to overproduction and diminishing returns for capital owners who engage in fierce price wars that aggravate deflationary pressures in a pure unregulated market. When capital owners are driven by competition they must work increasingly more for little or no marginal gain despite falling prices for consumers so price fixing or 'price leadership' becomes impossible. On a personal level, neijuan reflects a life of being overworked, stressed, anxious and feeling trapped, a lifestyle where many face the negative effects of living a very competitive life for nothing.

π Amplituhedron
An amplituhedron is a geometric structure introduced in 2013 by Nima Arkani-Hamed and Jaroslav Trnka. It enables simplified calculation of particle interactions in some quantum field theories. In planar N = 4 supersymmetric YangβMills theory, also equivalent to the perturbative topological B model string theory in twistor space, an amplituhedron is defined as a mathematical space known as the positive Grassmannian.
Amplituhedron theory challenges the notion that spacetime locality and unitarity are necessary components of a model of particle interactions. Instead, they are treated as properties that emerge from an underlying phenomenon.
The connection between the amplituhedron and scattering amplitudes is at present a conjecture that has passed many non-trivial checks, including an understanding of how locality and unitarity arise as consequences of positivity. Research has been led by Nima Arkani-Hamed. Edward Witten described the work as "very unexpected" and said that "it is difficult to guess what will happen or what the lessons will turn out to be".

π Usenet personality
A Usenet personality was a particular kind of internet personality who gained a certain level of notoriety from posting on the Usenet discussion forum. Since its inception, Usenet newsgroups have attracted a wide variety of users. Some posters achieved a certain amount of fame and celebrity within Usenet circles because of their unusual or humorous writings.

π Proxy Firm
A proxy firm (also a proxy advisor, proxy adviser, proxy voting agency, vote service provider or shareholder voting research provider) provides services to shareholders (in most cases an institutional investor of some type) to vote their shares at shareholder meetings of, usually, quoted companies.
The typical services provided include agenda translation, provision of vote management software, voting policy development, company research, and vote administration including vote execution. According to their websites, not all firms provide voting recommendations and those that do may simply execute client voting instructions.
The votes executed are called "Proxy Votes" because the shareholder usually does not attend the meeting and instead sends instructions - a proxy appointment - for a third party, usually the chairman of the meeting to vote shares in accordance with the instructions given on the voting card.
π 1983 United States Senate Bombing
The 1983 U.S. Senate bombing was a bomb explosion at the United States Senate on November 7, 1983, motivated by United States military involvement in Lebanon and Grenada. The attack led to heightened security in the DC metropolitan area, and the inaccessibility of certain parts of the Senate Building. Six members of the radical left-wing Resistance Conspiracy were arrested in May 1988 and charged with the bombing, as well as related bombings of Fort McNair and the Washington Navy Yard which occurred April 25, 1983, and April 20, 1984, respectively.
π British Expedition to Abyssinia
The British Expedition to Abyssinia was a rescue mission and punitive expedition carried out in 1868 by the armed forces of the British Empire against the Ethiopian Empire. Emperor Tewodros II of Ethiopia, then often referred to by the anglicized name Theodore, imprisoned several missionaries and two representatives of the British government in an attempt to get the attention of the British government, which had decided against his requests for military assistance. The punitive expedition launched by the British in response required the transportation of a sizable military force hundreds of miles across mountainous terrain lacking any road system. The formidable obstacles to the action were overcome by the commander of the expedition, General Sir Robert Napier, who was victorious in every battle with the troops of Tewodros, captured the Ethiopian capital and rescued all the hostages. The expedition was widely hailed on its return for achieving all its objectives.
Harold G. Marcus described the action as "one of the most expensive affairs of honour in history."
