Braess' paradox is the observation that adding one or more roads to a road network can slow down overall traffic flow through it. The paradox was postulated in 1968 by German mathematician Dietrich Braess, who noticed that adding a road to a particular congested road traffic network would increase overall journey time.
The paradox may have analogies in electrical power grids and biological systems. It has been suggested that in theory, the improvement of a malfunctioning network could be accomplished by removing certain parts of it. The paradox has been used to explain instances of improved traffic flow when existing major roads are closed.

The Iron Ring is a ring worn by many Canadian-trained engineers, as a symbol and reminder of the obligations and ethics associated with their profession. The ring is presented to engineering graduates in a private ceremony known as the Ritual of the Calling of an Engineer. The concept of the ritual and its Iron Rings originated from H. E. T. Haultain in 1922, with assistance from Rudyard Kipling, who crafted the ritual at Haultain's request.

The University of the Third Age is an international movement whose aims are the education and stimulation of mainly retired members of the community—those in their third 'age' of life. It is commonly referred to as U3A.
There is no universally accepted model for the U3A. Its original conception in France as an extramural university activity was significantly modified in the United Kingdom where it was recognized that most people of retirement age have something to contribute and the emphasis has been on sharing, without formal links to traditional universities.
Many English-speaking countries have followed this geragogic model, whereas continental European countries have mostly followed the French model. For historical reasons, Lifelong learning institutes is the term used in the United States for organizations that are similar to U3A groups.
A British U3A website reports this about "The Third Age" membership eligibility: "U3A membership is not related to a specific age but to a period in one’s life (the third age) after the second age of full-time employment and parental responsibility. Anybody in their third age can join U3A and this includes people who are working part-time. There is no lower age for membership."

The Peter principle is a concept in management developed by Laurence J. Peter, which observes that people in a hierarchy tend to rise to their "level of incompetence": employees are promoted based on their success in previous jobs until they reach a level at which they are no longer competent, as skills in one job do not necessarily translate to another. The concept was elucidated in the book The Peter Principle (William Morrow and Company, 1969) by Dr Peter and Raymond Hull.
Peter and Hull intended the book to be satire, but it became popular as it was seen to make a serious point about the shortcomings of how people are promoted within hierarchical organizations. Hull wrote the text, based on Peter's research. The Peter principle has been the subject of much subsequent commentary and research.

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 Uttar Pradesh Association of Dead People (Hindi: उत्तर प्रदेश मृतक संघ, Uttar Pradesh Mritak Sangh) is an Indian pressure group based in Azamgarh, Uttar Pradesh that seeks to reclaim the legal rights of those falsely listed by the Uttar Pradesh State government as being dead.
In the overcrowded regions of Uttar Pradesh, many have resorted to bribing officials to have the owner of a plot of land declared deceased and the title transferred to their ownership. The process to undo this is long, arduous, as well as often inefficient and corrupt. The Association seeks to reverse the declarations, call attention to the problem and prevent others from being exploited in similar fashion.
The founder and president is Lal Bihari, who was "dead" from 1976 to 1994 and used the word Mritak (Hindi: मृतक, transl. Dead) in his name during the period.
After being inspired by the story of Bihari, Indian film director Satish Kaushik made a movie Kaagaz, starring Pankaj Tripathi, based on his life. It was released on ZEE5 on 7 January 2021.
