In positive psychology, a flow state, also known colloquially as being in the zone, is the mental state in which a person performing an activity is fully immersed in a feeling of energized focus, full involvement, and enjoyment in the process of the activity. In essence, flow is characterized by the complete absorption in what one does, and a resulting transformation in one's sense of time.

Named by Mihály Csíkszentmihályi in 1975, the concept has been widely referred to across a variety of fields (and is particularly well recognized in occupational therapy), though the concept has been claimed to have existed for thousands of years under other names, notably in some Eastern thought systems, for example, Daoism and Buddhism.

The flow state shares many characteristics with hyperfocus. However, hyperfocus is not always described in a positive light. Some examples include spending "too much" time playing video games or watching television and getting side-tracked and pleasurably absorbed by one aspect of an assignment or task to the detriment of the overall assignment. In some cases, hyperfocus can "capture" a person, perhaps causing them to appear unfocused or to start several projects, but complete few. Other related concepts are trance, hypnosis, hypomania and mindfulness.

Plan 9 from Bell Labs is a distributed operating system, originating in the Computing Science Research Center (CSRC) at Bell Labs in the mid-1980s, and building on UNIX concepts first developed there in the late 1960s. The final official release was in early 2015.

Under Plan 9, UNIX's everything is a file metaphor is extended via a pervasive network-centric filesystem, and graphical user interface is assumed as a basis for almost all functionality, though it retains a heavily text-centric ideology.

The name Plan 9 from Bell Labs is a reference to the Ed Wood 1959 cult science fiction Z-movie Plan 9 from Outer Space. The name of the project's mascot is "Glenda, the Plan 9 Bunny". The system continues to be used and developed by operating system researchers and hobbyists.

On the morning of January 31, 2007, the Boston Police Department and the Boston Fire Department mistakenly identified battery-powered LED placards depicting the Mooninites, characters from the Adult Swim animated television series Aqua Teen Hunger Force, as improvised explosive devices (IEDs), leading to a massive panic. Placed throughout Boston, Massachusetts, and the surrounding cities of Cambridge and Somerville by Peter "Zebbler" Berdovsky and Sean Stevens, these devices were part of a nationwide guerrilla marketing advertising campaign for Aqua Teen Hunger Force Colon Movie Film for Theaters.

The massive panic led to controversy and criticism from U.S. media sources, including The Boston Globe, Los Angeles Times, Fox News, The San Francisco Chronicle, The New York Times, CNN, and The Boston Herald. Some ridiculed the city's response to the devices—including the arrests of the two men hired to place the placards around the area—as disproportionate and indicative of a generation gap between city officials and the younger residents of Boston, at whom the ads were targeted. Several sources noted that the hundreds of officers in the Boston police department or city emergency planning office on scene were unable to identify the figure depicted for several hours until a young staffer at Mayor Thomas Menino's office saw the media coverage and recognized the figures.

After the devices were removed, the Boston Police Department stated in its defense that the ad devices shared some similarities with improvised explosive devices, with them also discovering an identifiable power source, a circuit board with exposed wiring, and electrical tape. Investigators were not mollified by the discovery that the devices were not explosive in nature, stating they still intended to determine "if this event was a hoax or something else entirely". Although city prosecutors eventually concluded there was no ill intent involved in the placing of the ads, the city continues to refer to the event as a "bomb hoax" (implying intent) rather than a "bomb scare".

Reflecting years later, various academics and media sources have characterized the phenomenon as a form of social panic. Gregory Bergman wrote in his 2008 book BizzWords that the devices were basically a self-made form of the children's toy Lite-Brite. Bruce Schneier wrote in his 2009 book Schneier on Security that Boston officials were "ridiculed" for their overreaction to the incident. In his 2009 book Secret Agents, historian and communication professor Jeremy Packer discussed a cultural phenomenon called the "panic discourse" and described the incident as a "spectacular instance of this panic". In a 2012 article, The Boston Phoenix called the incident the "Great Mooninite Panic of 2007". A 2013 publication by WGBH wrote that the majority of Boston youth thought that the arrests of two men who placed devices were not justified.

A thought-terminating cliché (also known as a semantic stop-sign, a thought-stopper, bumper sticker logic, or cliché thinking) is a form of loaded language, commonly used to quell cognitive dissonance. Depending on context in which a phrase (or cliché) is used, it may actually be valid and not qualify as thought-terminating; it does qualify as such when its application intends to dismiss dissent or justify fallacious logic. Its only function is to stop an argument from proceeding further, in other words "end the debate with a cliche... not a point." The term was popularized by Robert Jay Lifton in his 1961 book Thought Reform and the Psychology of Totalism, who called the use of the cliché, along with "loading the language", as "The language of Non-thought".

Stochastic resonance (SR) is a phenomenon where a signal that is normally too weak to be detected by a sensor, can be boosted by adding white noise to the signal, which contains a wide spectrum of frequencies. The frequencies in the white noise corresponding to the original signal's frequencies will resonate with each other, amplifying the original signal while not amplifying the rest of the white noise (thereby increasing the signal-to-noise ratio which makes the original signal more prominent). Further, the added white noise can be enough to be detectable by the sensor, which can then filter it out to effectively detect the original, previously undetectable signal.

This phenomenon of boosting undetectable signals by resonating with added white noise extends to many other systems, whether electromagnetic, physical or biological, and is an area of research.

The No Asshole Rule: Building a Civilized Workplace and Surviving One That Isn't is a book by Stanford professor Robert I. Sutton. He initially wrote an essay for the Harvard Business Review, published in the breakthrough ideas for 2004. Following the essay, he received more than one thousand emails and testimonies. Among other reasons disclosed in another article published at the Harvard Business Review, these letters led him to write the book, sell more than 115,000 copies, and win the Quill Award for best business book in 2007.

The theme of this book is that workplace bullying worsens morale and productivity. To screen out the toxic staff, it suggests the "no asshole rule". The author insists upon use of the word asshole since other words such as bully or jerk "do not convey the same degree of awfulness". In terms of using the word in the book's title, he said "There's an emotional reaction to a dirty title. You have a choice between being offensive and being ignored."

The word dord is a dictionary error in lexicography. It was accidentally created, as a ghost word, by the staff of G. and C. Merriam Company (now part of Merriam-Webster) in the New International Dictionary, second edition (1934). That dictionary defined the term a synonym for density used in physics and chemistry in the following way: "dord (dôrd), n. Physics & Chem. Density."

Philip Babcock Gove, an editor at Merriam-Webster who became editor-in-chief of Webster's Third New International Dictionary, wrote a letter to the journal American Speech, fifteen years after the error was caught, in which he explained how the "dord" error was introduced and corrected.

On 31 July 1931, Austin M. Patterson, the dictionary's chemistry editor, sent in a slip reading "D or d, cont./density." This was intended to add "density" to the existing list of words that the letter "D" can abbreviate. The phrase "D or d" was misinterpreted as a single, run-together word: Dord. This was a plausible mistake, because headwords on slips were typed with spaces between the letters, so "D or d" looked very much like "D o r d". The original slip went missing, so a new slip was prepared for the printer, which assigned a part of speech (noun) and a pronunciation. The would-be word was not questioned or corrected by proofreaders. The entry appeared on page 771 of the dictionary around 1934, between the entries for Dorcopsis (a type of small kangaroo) and doré (golden in color).

On 28 February 1939, an editor noticed "dord" lacked an etymology and investigated, discovering the error. An order was sent to the printer marked "plate change/imperative/urgent". The non-word "dord" was excised; "density" was added as an additional meaning for the abbreviation "D or d" as originally intended, and the definition of the adjacent entry "Doré furnace" was expanded from "A furnace for refining dore bullion" to "a furnace in which dore bullion is refined" to close up the space. Gove wrote that this was "probably too bad, for why shouldn't dord mean 'density'?" In 1940, bound books began appearing without the ghost word, although inspection of printed copies well into the 1940s show "dord" still present. The entry "dord" was not completely removed until 1947.

A Feynman sprinkler, also referred to as a Feynman inverse sprinkler or as a reverse sprinkler, is a sprinkler-like device which is submerged in a tank and made to suck in the surrounding fluid. The question of how such a device would turn was the subject of an intense and remarkably long-lived debate.

A regular sprinkler has nozzles arranged at angles on a freely rotating wheel such that when water is pumped out of them, the resulting jets cause the wheel to rotate; both a Catherine wheel and the aeolipile ("Hero's engine") work on the same principle. A "reverse" or "inverse" sprinkler would operate by aspirating the surrounding fluid instead. The problem is now commonly associated with theoretical physicist Richard Feynman, who mentions it in his bestselling memoirs Surely You're Joking, Mr. Feynman! The problem did not originate with Feynman, nor did he publish a solution to it.

Although people in many parts of the world share common alphabets and numeral systems (versions of the Latin writing system are used throughout the Americas, Australia, and much of Europe and Africa; the Arabic numerals are nearly universal), styles of handwritten letterforms vary between individuals, and sometimes also vary systematically between regions.
