A ghost light is an electric light that is left lit on the stage of an unoccupied theater. It typically consists of an exposed bulb mounted in a wire cage on a portable light stand near center stage. Ghost lights are also sometimes known as ‘equity lights’ or ‘equity lamps,’ possibly indicating their use was originally mandated by the Actors’ Equity Association. A ghost light enables one to navigate the theater to find the lighting control console and to avoid accidents such as falling into the orchestra pit or damaging set pieces. Aside from its obvious practical purpose, there are a number of superstitions associated with the origin and purpose of ghost lights.
A popular legend holds that every theater has a ghost. Some theaters have traditions to appease ghosts that reach far back into their history. For example, the Palace Theatre, London keeps two seats in their balcony permanently bolted open to provide seating for the theater ghosts. Similar superstitions hold that ghost lights provide opportunities for ghosts to perform onstage, thus appeasing them and preventing them from cursing the theater or sabotaging the set or production. The use of ghost lights might also be a throwback to the 1800s when theaters were lit with gas lamps. Leaving a flame burning would prevent the buildup of pressure in the gas lines which could cause an explosion.

The smart cow problem refers to the fact that when a group of individuals is faced with a technically difficult task, only one of their members has to solve it. When the problem has been solved once, an easily repeatable method may be developed, allowing the less technically proficient members of the group to accomplish the task.
The concept is relevant to copyright protection schemes such as DRM (Digital Rights Management), where, due to the rapid spread of information on the Internet, it only takes one individual’s defeat of a DRM technology to render the method obsolete. The term ‘smart cow’ is thought to be derive from the expression: ‘It only takes one smart cow to open the latch of the gate, and then all the other cows follow.’

Stewart Brand (b. 1938) is an American writer, best known as editor of the ‘Whole Earth Catalog,’ a counterculture magazine and mail order catalog. He founded a number of organizations, including The WELL (one of the oldest virtual communities in continuous operation), the Global Business Network (a scenario planner and forecaster for companies, NGOs, and governments), and the Long Now Foundation (a nonprofit that promotes very long-term projects, e.g. a 10,000 year clock). He is the author of several books, most recently ‘Whole Earth Discipline: An Ecopragmatist Manifesto.’
Brand attended Phillips Exeter Academy. He studied biology at Stanford University, graduating in 1960. His first marriage was to Lois Jennings, an Ottawa Native American and mathematician. As a soldier in the Army, he was a parachutist and taught infantry skills; he later expressed the view that his experience in the military had fostered his competence in organizing. A civilian again in 1962, he studied design at San Francisco Art Institute, photography at San Francisco State College, and participated in a legitimate scientific study of then-legal LSD, in Menlo Park, California.

Phantom vibration syndrome or ‘phantom ringing’ is the mistaken feeling that one’s mobile phone is vibrating or ringing. Other terms for this concept include ringxiety (a portmanteau of ‘ring’ and ‘anxiety’) and ‘fauxcellarm’ (a play on ‘false alarm’). It is a form of pareidolia, a psychological phenomenon involving a stimulus (such as an image or a sound) wherein the mind perceives a familiar pattern where none actually exists. Phantom ringing may be experienced while taking a shower, watching television, or using a noisy device. Humans are particularly sensitive to auditory tones between 1,000 and 6,000 hertz, and basic mobile phone ringers often fall within this range.
In the comic strip ‘Dilbert,’ cartoonist Scott Adams referenced such a sensation in 1996 as ‘phantom-pager syndrome.’ The earliest published use of the term dates to a 2003 article in the ‘New Pittsburgh Courier,’ written by Robert D. Jones. In the conclusion of the article, Jones writes, ‘…should we be concerned about what our mind or body may be trying to tell us by the aggravating imaginary emanations from belts, pockets and even purses? Whether PVS is the result of physical nerve damage, a mental health issue, or both, this growing phenomenon seems to indicate that we may have crossed a line in this ‘always on’ society.’

Functional fixedness [fiks-ed-nes] is a cognitive bias that limits a person to using an object only in the way it is traditionally used. The concept originated in Gestalt Psychology, which emphasizes holistic processing (e.g., ‘the whole is greater than the sum of its parts’). German American psychologist Karl Duncker defined functional fixedness as a ‘mental block against using an object in a new way that is required to solve a problem.’ This ‘block’ limits the ability of an individual to use components given to them to complete a task, as they cannot move past the original purpose of those components.
For example, if someone needs a paperweight, but they only have a hammer, they may not see how the hammer can be used as a paperweight. Functional fixedness is this inability to see a hammer’s use as anything other than for pounding nails; the person couldn’t think to use the hammer in a way other than in its conventional function. When tested, five year old children show no signs of functional fixedness. At that age, any goal to be achieved with an object is equivalent to any other goal. However, by age seven, children have acquired the tendency to treat the originally intended purpose of an object as special.

A user error is an error made by the human user of a complex system, usually a computer system, in interacting with it. Related terms such as PEBCAK (Problem Exists Between Chair And Keyboard), ID-10T error (idiot error), and other similar phrases are also used as slang in technical circles with derogatory meaning. A highly popularized example of this is a user mistaking their CD-ROM tray for a cup holder, or a user looking for the ‘any key.’
This usage implies a lack of computer savvy, asserting that problems arising when using a device are the fault of the user. Critics of the term argue that the problems are caused instead by a device that doesn’t take into account human limitations and is thus designed in a way that induces errors.

‘The Truth Machine‘ is a 1996 science fiction novel by James L. Halperin about an infallible lie detector. Soon, every citizen must pass a thorough test under a Truth Machine to get a job or receive any sort of license. Eventually, people begin wearing them all the time, thus eliminating dishonesty in all parts of human interaction, including most crime, terrorism and a great deal of general social problems.
The novel focuses on the life story of the machine’s inventor, Pete Armstrong, a child prodigy whose life has been defined by the tragic murder of his younger brother, Leonard, by an ex-convict who was believed to be capable of committing violent crimes again, but who could not be incarcerated on mere suspicions. Armstrong claimed that as long as it was employed universally (and not just by government officials), the ‘truth machine’ could revolutionize humanity and take it to that next evolutionary step. However, the protagonist places a back door in the device, allowing him to avoid detection when he repeats fragments of Walt Whitman’s poem ‘O Captain! My Captain!’ in his mind.

‘The Cuckoo’s Egg: Tracking a Spy Through the Maze of Computer Espionage’ is a 1989 book written by Clifford Stoll, an astronomer turned systems administrator of the computer center of the Lawrence Berkeley Laboratory (LBL) in California. It is his first-person account of the hunt for a computer hacker who broke into a computer at the lab.
In August of 1986 his supervisor asked him to resolve a US$0.75 accounting error in the computer usage accounts. He traced the error to an unauthorized user who had apparently used up nine seconds of computer time and not paid for it, and eventually realized that the unauthorized user was a hacker who had acquired root (high-level) access to the LBL system by exploiting a vulnerability in the movemail function of the original GNU Emacs (an open-source computer program that moves a user’s mail to another file).

Vimāna [vi-mah-nuh] is a mythological flying palace or chariot described in Hindu texts and Sanskrit epics. The Pushpaka Vimana of the demon king Ravana is the most quoted example. Vimanas are also found in Jain texts. The word literally means ‘measuring out, traversing.’
Oxford Sanskrit scholar Monier Monier-Williams defined it as ‘a car or a chariot of the gods, any mythical self-moving aerial car (sometimes serving as a seat or throne, sometimes self-moving and carrying its occupant through the air; other descriptions make the Vimana more like a house or palace, and one kind is said to be seven stories high).’ It may denote any car or vehicle, especially a bier (a wheeled altar for transporting coffins), or a ship as well as a palace of an emperor, especially with seven stories.

The Lowline, formally known as the Delancey Underground, is a proposal for the world’s first underground park. The subterranean public space would be located under the eastbound roadway of Delancey Street on the Lower East Side of Manhattan (adjacent to the Essex Street station).
Co-founders James Ramsey and Dan Barasch have suggested natural light would be directed below ground using fiber optics—described in the proposed plan as ‘remote skylights’—to provide an area in which trees and grass could be grown beneath the city streets.

The tiny house movement is a popular description for the architectural and social movement that advocates living simply in small homes. In the US the average size of new single family homes grew from 1,780 square feet in 1978 to 2,479 in 2007, despite a decrease in the size of the average family. Reasons for this include increased material wealth and prestige. The small house movement is a return to houses less than 1,000 square feet, some as small as 80 square feet.
Sarah Susanka has been credited with starting the recent countermovement toward smaller houses when she published ‘The Not So Big House’ in 1997. Earlier pioneers include Lloyd Kahn, author of ‘Shelter’ in 1973.’ Tiny houses on wheels were popularized by Jay Shafer who designed and lived in a 96 sq ft house and later went on to offer the first plans for tiny houses on wheels, initially founding ‘Tumbleweed Tiny House Company,’ and then ‘Four Lights Tiny House Company’ in 2012.

Presence is the illusion that a virtual experience is real. Today, it often considers the effect that people experience when they interact with a computer-mediated or computer-generated environment. This use of the term derives from the word ‘telepresence,’ coined by MIT professor Marvin Minsky in 1980, which he described as the manipulation of objects in the real world through remote access technology. For example, a surgeon may use a computer to control robotic arms to perform minute procedures on a patient in another room. Or a NASA technician may use a computer to control a rover to collect rock samples on Mars.
As technologies progressed, the need for an expanded term arose. Thomas Sheridan (also of MIT, and a pioneer of robotics and remote control technology) extrapolated Minsky’s original definition. Using the shorter ‘presence,’ Sheridan explained that the term refers to the effect felt when controlling real world objects remotely as well as the effect people feel when they interact with and immerse themselves in virtual reality or virtual environments.
