(13) In political history as Stunde Null (a German military planning term meaning "Hour Zero"), a term referring to midnight on 8 May 1945 in Germany marking the end of World War II in Europe and the birth a new Germany (an attempt to dissociate post-war Germany from the Nazis).  The period immediately following this time is the Nachkriegszeit (the time after the war).

(14) One of the beads in nulled work (an ornamental craft producing work resembling beads strung on a rod).

1555–1565: From the Middle French nul, from the Latin nūllus from the Proto-Italic ne-oino-los from Proto-Italic oinos (one).  Synchronically nūllus was from ne (not) + ūllus (any) and thus meaning literally "not any".  The earlier form nulla (circa 1500), from the Italian nulla, from the Latin nūlla, feminine of nūllus (no one) was ultimately from the primitive Indo-European ne, óynos & -lós.  Null is a noun, adjective & verb, nulled is a verb & adjective, nulling is a noun & verb, nullity, nullification & nullificationist are nous and nullify, nullified & nullifying are verbs; the common nouns plural are nulls and nullings.

Null Island.

Null Island is an imaginary island located at 0°N 0°E (thus “Null”, zero being one of null’s synonyms) in the South Atlantic Ocean, the point at which equator crosses the prime meridian.  It’s not clear when Null Island was first “discovered” but it delighted many when in 2011 it appeared on Natural Earth, a public domain map dataset created by volunteer cartographers and GIS (geographic information system) analysts.  A modest 1m² "land mass" (actually a buoy) located at 0°N 0°E in the digital dataset, Null Island was intended to help analysts flag errors in geocoding.  Somewhat analogous with the DNS (Domain Name System) which maintains a relationship between IP (Internet Protocol) addresses (which with computer networks communicate) and the familiar website names (which real people use), geocoding is a process which converts a physical address (such as a street address) into geographic coordinates, the most familiar of which are latitude and longitude.  It permits address to appear on digital maps and enables location-based services and applications to be integrated and distributed, mapping, navigation & advertising services depending on the system.  Of late, a particularly helpful application of the service has been the tracking of the spread of diseases. 

IBM & Null

In 1981, IBM explained why, in file systems, null had to exist in every directory (now often called folders).  If null didn’t exist, IBM maintained, operating systems wouldn’t necessarily be able to determine which were empty.  Advances in operating systems over forty-odd years, mean that’s no longer a problem but with the technology available in 1981, some of it dating back decades, the issue was real.  IBM also published what turned out to be a prescient vision of what became the widely distributed file systems of the internet, spread across continents, running on disparate hardware and operating systems yet able still functionally and administratively to interact.  Modern programming languages still take advantage of the existence (or non-existence) of null.  Below is a Python script to both check if a directory is empty and also check for exceptional situations such as a directory not existing.

import os
def main():
    dirName = '/home/varun/temp';
    '''
        Check if a Directory is empty and also check exceptional situations.
    '''   
    if os.path.exists(dirName) and os.path.isdir(dirName):
        if not os.listdir(dirName):
            print("Directory is empty")
        else:   
            print("Directory is not empty")
    else:
        print("Given Directory don't exists")
    '''
        Check if a Directory is empty : Method 1
    '''   
    if len(os.listdir('/home/varun/temp') ) == 0:
        print("Directory is empty")
    else:   
        print("Directory is not empty")
    '''
        Check if a Directory is empty : Method 2
    '''   
    if not os.listdir('/home/varun/temp') :
        print("Directory is empty")
    else:   
        print("Directory is not empty")
    print ("****************")
if __name__ == '__main__':
    main()
Output:
Directory is empty
Directory is empty
Directory is empty

In the commercial art business, if no frame is chosen, the order is tagged "Null Frame".

In computer programming, the "null frame" is a data packet containing no useful information and existing usually for the purposes of (1) maintaining an open comms channel or (2) as a marker for an end of transmission.  Null Frames are often used in conjunction with “heartbeat” (or “keepalive”) markers which provide a visual symbol indicating a connection remains active.  However, because null frames can be of variable size, they’re of use also as markers of the addressable space available in memory or buffers.  While there are other ways of doing this, null frames provide information about resource availability while themselves consuming almost no resources.  In the commercial art business, the expression “null frame” is used to indicate the customer has specified the product be supplied unframed.

Erase

Erase (pronounced ih-reys)

(1) To rub or scrape out, as letters or characters written, engraved etc; efface.

(2) Completely to eliminate.

(3) To remove material recorded on magnetic tape or magnetic disk; synonymous for most purposes in this context with delete although technically, in computing, an erasure is the substitution of data with characters representing a null value whereas a deletion is the removal of an pointer entry in an index.

1595–1605: From the Middle English arasen & aracen (to eradicate, remove), from the Latin ērāsus, past participle of ērādere (scrape out, scrape off, shave, abolish, remove, to abrade), the construct being ex (out of) + radere (to scratch, scrape).  The use in the context of data on magnetic storage media (tapes, disks) dates from 1945, the technical distinction between erase and delete defined in computer science theory as early as 1947 though, to this day, the distinction escapes most users.  The adjective erasable dates from 1829.  Eraser (thing that erases writing) is attested from 1790, an invention of American English, agent noun from erase.  Originally, the product was a knife with which to scraping off ink, the first rubber devices for removing pencil marks not available until from 1858.

Erasure, Comrade Stalin and Lindsay Lohan

Evil dictators (like those running beach clubs or Greek islands) have their problems too and they like them to go away.  Where problems exist, they like them to be erased or is some other way to disappear.  Sometimes, the technical term is “unpersoned”.

The Erased

Not best pleased at images of the pleasingly pneumatic Karolina Palazi appearing on the official Lohan Beach Club Mykonos Beach Club Instagram account, Lindsay Lohan quickly responded with a post demanding her staff “Erase this random person at my beach”.  In the digital age, it can be difficult entirely to erase anything which appears on the internet and probably impossible for anything distributed on the big-data social media platforms.  That said, there is unpredictability to the fate of anything ever on-line.  There is (1) material which genuinely vanishes forever, (2) stuff which proves impossible to eradicate despite best efforts, and (3) things which were thought lost, only to re-appear.  Noted for some time, the issue will be of increasing interest in the future, the internet being a distributed system with no centralised repository indicating what is held where, by whom and whether it is accessible (by someone) on or off-line or in storage.

The Disappeared

General Augusto Pinochet (1915–2006; military dictator of Chile 1973-1990).

This is the relatively new name for the centuries-old practice of secretly kidnapping or arresting people, then imprisoning or killing them, all without due process of law.  It’s most associated with the late twentieth-century military dictatorships in Chile, Argentina and Brazil but is used to describe the practice in many South and Central American republics and of late, others, sometimes at scale.  Although the practice probably pre-dates even modern humans, the word, in this context appears first to have been used by Joseph Heller (1923–1999) in the satirical Catch-22 (1961) when describing how the US military dealt with malcontents.  However it’s done, the person disappears without trace.

The Unpersoned

Unpersoning wasn’t invented in the Soviet Union but it was under comrade Stalin (1878-1953; Soviet leader 1924-1953) it was undertaken at scale, although, like later attempts on the internet, the process wasn’t always perfect because it was performed on extant physical material, some of which inevitably escaped attention.  The process interested critics in the West; in George Orwell's (1903–1950), dystopian novel Nineteen Eighty-Four (1949), protagonist Winston Smith works at the Ministry of Truth where his job is to alter historical records to conform to the state's ever-changing version of history.  Done in the USSR mostly between 1928-1953, unpersoning was the physical modification of existing text and imagery, modified to erase from history those who had fallen from favor and it’s thought the most extensively unpersoned figure in the USSR was comrade Leon Trotsky (1879-1940).  Comrade Stalin had him murdered in Mexico, the assassin's choice of weapon an ice axe.

Erased from history: Before & after being unpersoned, Comrades Molotov (1890-1986) & Stalin with Comrade Nikolai Yezhov (1895-1940), head of the NKVD (one of the predecessors of the KGB); Comrade Stalin had him shot.

In the Soviet Union, the process was essentially as Orwell described and even in the age of digital editing it's probably often still done in a similar manner.  A photograph would be passed to the party's technicians with the comrade(s) to be unpersoned marked in some obvious way, the preferred technique apparently a black crayon.

Succeeding where others failed: Erasing crooked Hillary Clinton

The White House situation room, 2 May 2011 (official WH photo; left) and as depicted in Di Tzeitung (right).

Unpersoning can also be sex-specific (gender-based the currently preferred term).  In May 2011, the Orthodox Jewish news paper Di Tzeitung (a Brooklyn-based weekly) was forced to apologize after unpersoning the women in the photograph released by the White House showing President Barack Obama (b 1961; US president 2009-2017) and his staff monitoring the raid by US Navy Seals in which Osama bin Laden (1957-2011) was killed while in his Pakistani compound.  Unpersoned were then counterterrorism director, Audrey Tomason (b circa 1977) and then secretary of state, crooked Hillary Clinton (b 1947; US secretary of state 2009-2013).  Di Tzeitung's subsequent apology was somewhat nuanced.  The publication reiterated it did not publish images of women and thus sent its “regrets and apologies” to the White House and the State Department, not because it had unpersoned women but because their photo editor had not read the “fine print” in the text issued by the White House (which accompanied the photograph) which forbid any changes.  Di Tzeitung further explained it has a “long standing editorial policy” of not publishing images of women because its readers “believe that women should be appreciated for who they are and what they do, not for what they look like and the Jewish laws of modesty are an expression of respect for women, not the opposite”.  They added that Di Tzeitung regarded crooked Hillary Clinton (a former US senator (Democrat) for New York who secured overwhelming majorities in the Orthodox Jewish communities) highly and “appreciated her unique capabilities, talents and compassion for all”.  It concluded by acknowledging it “should not have published the altered picture”.  Commentators noted the practice is not unusual in some ultra-Orthodox Jewish publications which regard depictions of the female form as “immodest”.  Neither the White House nor the State Department responded to the apology although there were cynics who wondered if the president wished it were that easy to get rid of crooked Hillary.

The Watergate tapes and the erased 18½ minutes

Looking over his shoulder: Richard Nixon and HR Halderman in the White House.

Tapes, audio and video, have played a part in many political downfalls but none is more famous than the “smoking gun” tape which compelled the resignation of Richard Nixon (1913-1994; US president 1969-1974) after it revealed he was involved in the attempt to cover-up the involvement in the Watergate break-in of some connected to his administration.  Recording conversations in the White House had been going on for years and Nixon initially had the equipment removed, the apparatus re-installed two years later after it was found there was no other way to ensure an accurate record of discussions was maintained.  Few outside a handful of the president’s inner circle knew of the tapes and they became public knowledge only in mid-1973 when, under oath before a congressional hearing, a White House official confirmed their existence.  That was the point at which Nixon should have destroyed the tapes and for the rest of his life he must sometimes have reflected that but for that mistake, his presidency might have survived because, although by then the Watergate scandal had been a destabilizing distraction, there was at that point no “smoking gun”, nothing which linked Nixon himself to any wrongdoing.  As it was, he didn’t and within days subpoenas were served on the White House demanding the tapes and that made them evidence; the moment for destruction had passed.  Nixon resisted the subpoenas, claiming executive privilege and thus ensued the tussle between the White House and Watergate affair prosecutors which would see the “Saturday Night Massacre” during which two attorneys-general were fired, the matter ultimately brought before the US Supreme Court which ruled against the president.  Finally, the subpoenaed tapes were surrendered on 5 August 1973, the “smoking gun” tape revealing Nixon and his chief of staff (HR Haldeman, 1926–1993; White House chief of staff 1969-1973) discussing a cover-up plan and at that point, political support in the congress began to evaporate and the president was advised that impeachment was certain and even Republican senators would vote to convict.  On 8 August, Nixon announced his resignation, leaving office the next day.

Uher 5000 reel-to-reel tape recorder used by a White House secretary to create the tape (20 June 1972) with the 18½ minute gap.  (Government Exhibit #60: Records of District Courts of the United States, Record Group 21. National Archives Identifier: 595593).

To this day, mystery surrounds one tape in particular, a recording of a discussion between Nixon and Halderman on 20 June 1972, three days after the Watergate break-in.  Of obviously great interest, when reviewed, there was found to be a gap of 18½ minutes, the explanations offered of how, why or by whom the erasure was effected ranging from the humorously accidental to the darkly conspiratorial but half a century on, it remains a mystery.  Taking advantage of new data-recovery technology, the US government did in subsequent decades make several attempts to “un-delete” the gap but without success and it may be, given the nature of magnetic tape, that there is literally nothing left to find.  However, the tape is stored in a secure, climate-controlled facility in case technical means emerge and while it’s unlikely the contents would reveal anything not already known or assumed, it would be of great interest to historians.  What would be even more interesting is the identity of who it was that erased the famous 18½ minutes but that will likely never be known; after fifty years, it’s thought that were there to be any death-bed confessions, they should by now have been heard.  Some have their lists of names of those who might have "pressed the erase button" and while mostly sub-sets of Watergate's "usual suspects", one who tends not to appear is Nixon himself, the usual consensus being he was technically too inept to operate a tape machine though it's not impossible he ordered someone to do the deed.  However it happened, the suspects most often mentioned as having had their "finger on the button" (which may have been a foot-pedal) are Nixon's secretary and his chief of staff.

Void

Void (pronounced void)

(1) In law, having no legal force or effect; not legally binding or enforceable.

(2) Useless; ineffectual; vain; devoid; destitute (usually followed by of).

(3) Without contents; empty.

(4) Without an incumbent, as an office.

(9) A gap or opening, as in a wall.

(10) A vacancy; vacuum.

(11) In typography, inside area of a character of type, such as the inside of an O.

(12) To make ineffectual; invalidate; nullify.

(14) To depart from; to vacate (archaic).

(15) In computer programming, a function or method that does not return a value.

(16) In architecture, a differentiated treatment of space.

1250–1300: The adjectival form was from the Middle English voide & voyde, from the Anglo-French & Old French voide, voit, vuide, & vuit (source also of the Modern French vide), from the unattested Vulgar Latin vocīta & vocita, feminine of vocītus & vocitus, an unattested and dissimilated variant of the Latin vacīvus, vacuus & vocīvus, (empty) from vacāre (to be empty).  The verb was from the Middle English voiden, from the Anglo-French voider, from the Old French, from the unattested Vulgar Latin vocitāre, derivative of the unattested vocītus & vocitus, noun derivative of the adjective.  Root was the primitive Indo-European wak-, an extended form of the root eue- (to leave, abandon, give out).

Void circa 1300 was first a verb (to clear some place of something) with the meaning "to deprive (something) of legal validity" attested from the early fourteenth century.  The adjectival sense evolved in parallel with the verb, again circa 1300, the meaning "unoccupied, vacant" soon extending to "empty, vast, wide, hollow, waste, uncultivated, fallow" and as a noun, "opening, hole; loss".  The meaning "lacking or wanting (something)” is recorded from the early 1400s while "legally invalid, without legal efficacy" is attested from the mid fifteenth century.  The adjective voidable is from the late fifteenth century 15c; the sense of an "unfilled space, gap" dates from the 1610s and the meaning "absolute empty space, vacuum" is from 1727.  Voider and voidness are both derived nouns.

In diplomacy

In fourteenth century Europe, French was the most widely-spoken language and in 1539, the court of Francis I (1494–1547; King of France 1515-1547) declared French to be the official language of government.  It was in this era that diplomacy began to assume a recognizably modern form with an increasingly consistent use of titles, conventions and institutions.  From this position of cultural hegemony, French emerged as the language of diplomacy, a position enhanced as the European colonial empires expanded.  It wouldn’t be until well into the twentieth century, under mostly US influence, that English began first to run in parallel as a language of diplomacy and later to assume primacy, English and French being the first two official languages of the United Nations (UN).  However, the linguistic legacy endures in the handbooks of diplomacy which include the standardized titles and phrases of the profession.  One phrase still used is that when one diplomat refuses to accept a message from another, returning the envelope to the sender marked nul et non avenue (literally “null and void”), creating the diplomatic fiction the envelope was unopened and the message thus unread, thereby relieving both parties of the need to pursue the unpleasantness.

In architecture

Once reduced, in architecture there’s only form and space but it’s helpful to imagine some space as part of the form so there’s thus form, space and void, void being a space defined by the form and theorists layer this further by distinguishing between voids cognitive and functional.  Cognitive voids are those created for emotional and perceptional impact, a kind of (usually static) visual effect whereas functional voids fulfil a technical requirement, typically ventilation or the movement of people.  Theorists tend to classify cognitive voids in the language of art: conceptual, perceptual, or sculptural while the functional are grouped by traditional terms from architecture: as entrance, courtyard, circulation etc.  In the analysis of the theorists, cognitive voids exist either as transparent or permeable spaces, the former most used to create perceptual effects, the latter for the visual.

Functional void: Grand Central Terminal (the official abbreviation is GCT although the popular form is "Grand Central Station" (often clipped to "Grand Central")), Midtown Manhattan, New York City, 1929.

Unfortunately, the clerestories which once shone no longer shine.  Because of more recent development in the surrounding space, the sunlight no longer enters the CCT's void through the clerestoried windows is such an eye-catching way (left).  In modern skyscrapers, light-shafts or atriums can extend hundreds of feet to ensure what sunlight is available can be captured; there's now often little at ground level.  When the a scene from the Lindsay Lohan film Just my Luck (2006) (right) was shot in the GCT, it was in a dimmer ambiance.  

Photon

Photon (pronounced foh-ton)

The subatomic particle that carries the electromagnetic force and is the quantum of electromagnetic radiation; has a rest mass of zero, but has measurable momentum, exhibits deflection by a gravitational field, and can exert a force.  It has no electric charge, has an indefinitely long lifetime, and is its own antiparticle.  It is the quantum (a bundle of energy) in which light and other forms of electromagnetic radiation are emitted.

1916: A compound word phot(o)- +‎ -on.  Photo is from the Ancient Greek combining form φωτω- (phōtō-) from φῶς (phôs) (light).  The –on suffix is used often in science, in physics (eg electron) and in chemistry (eg carbon) and is from the Ancient Greek -ον (-on), used when ending neuter nouns and adjectives.  In physics, mathematics and biology, it forms nouns denoting subatomic particles (proton), quanta (photon), molecular units (codon), or substances (interferon).  In biology and genetics, it’s applied to form names of stuff considered basic or fundamental units such as codon.  In chemistry, it’s used to form names of noble gases and certain nonmetal elements such as boron or silicon.  Photon was coined in 1916 by US physicist Leonard Troland (1889-1932) as a unit of light hitting the retina but the word was little used until the 1920s when a number of scientific papers were published.  Although the findings of some of the early experiments were later disproved, the word was soon adopted by most physicists.  Photon is a noun and photonic an adjective; the noun plural is photons.  

The light quantum

The photon is also called the light quantum.  The Latin word quanta (how much; the singular form is quantum) was used in the nineteenth century to mean particles or as a measure of quantity, the latter meaning persisting in general use.  What light was actually made from was, until the early twentieth century, one of the fundamental arguments in physics; the dispute essentially whether light was a wave or a particle.  Albert Einstein (1879-1955) published his theory in a 1905 paper which described electromagnetic waves as “…spatially localized, discrete wave-packets” which he labeled das lichtquant (the light quantum).  Light has special characteristics: apart from being creation’s universal speed limit, photons have a unique property in that they are both a particle and a wave, almost certainly have no mass and carry no charge.

JPL (NASA's Jet Propulsion Laboratory) used the properties of the photon to illustrate the weird world of quantum theory.

Photons underlie Einstein’s theory of relativity.  Travelling at the speed of light (and light can be slowed-down or stopped), if a photon could visualize, the entire universe would appear as a two-dimensional timeless plane which is completely still.  However, a photon can’t visualize or even experience anything because, for a proton, time doesn't pass, physicists labeling such things null geodesics.  A photon moves from its start to its end: An interaction creates (or emits) it until another interaction destroys (or absorbs) it.  These two things, creation and destruction, are all that can happen to a photon and neither can be experienced because there’s no time; what photons do can be measured but the frame of reference is wholly external.  In an inertial reference frame, there are physical laws which don't depend on the motion of anything external to the system yet for a photon, the physical rules it obeys depend exclusively on everything which happens external to it.

Weirder still, because protons lack mass, a photon cannot visualize the rest of the universe because seeing requires interacting with other particles, antiparticles, or photons, and, once such an interaction occurs, that photon's journey is over, its destruction as instantaneous as its creation.  Thus the fundamental importance of time to the existence of three-dimensional space; were there no time, everything would happen at once.

Apostolic

Apostolic (pronounced ap-uh-stol-ik)

(1) Of or characteristic of an apostle.

(2) Pertaining to or characteristic of the twelve apostles.

(3) Derived from the apostles in regular succession as bishops.

(4) Of or relating to the pope as being chief successor of the apostles.

1540–1550: From the French apostolique (pertaining to, related to, or descended from the apostles), from the Church Latin apostolicus (apostolic), from the Ancient Greek ἀποστολικός (apostolikós) (apostolic), from apostolos.  The derived form apostolical emerged also in the fifteenth century.  The construct in the Church Latin apostolicus was apóstol(os) + -ic.  The suffix -ic is from the Middle English -ik, from the Old French -ique, from the Latin -icus, from the primitive Indo-European -kos & -ḱos, formed with the i-stem suffix -i- and the adjectival suffix -kos & -ḱos.  The form existed also in the Ancient Greek as -ικός (-ikós), in Sanskrit as -इक (-ika) and the Old Church Slavonic as -ъкъ (-ŭkŭ); A doublet of -y.  In European languages, adding -kos to noun stems carried the meaning "characteristic of, like, typical, pertaining to" while on adjectival stems it acted emphatically; in English it's always been used to form adjectives from nouns with the meaning “of or pertaining to”.  A precise technical use exists in physical chemistry where it's used to denote certain chemical compounds in which a specified chemical element has a higher oxidation number than in the equivalent compound whose name ends in the suffix -ous; (eg sulphuric acid (H₂SO₄) has more oxygen atoms per molecule than sulphurous acid (H₂SO₃).

Apostolic succession

Apostolic succession is the term describing the method through which the ministry of the Roman Catholic Church is held to derive its unique validity by virtue of an unbroken chain of succession from the twelve apostles (or disciples) of Christ.  The mechanics of this are that every bishop is ordained by a previously ordained bishop and that linkage reaches back two millennia to the apostles.  The purity of apostolic succession is an important part of the mystique of the Roman Catholic Church and the Vatican maintains the linkage is exclusive to them, the schism of 1534, in which Henry VIII (1491–1547; King of England 1509-1547) separated the English Church from Rome, sundering also the apostolic succession.  Fearing some doubts might exist, Pope Leo XIII (1810–1903; pope 1878-1903) in 1896 delivered Apostolicae Curae, stating all the Church of England’s ordinations were "…absolutely null and utterly void…".

In terms of canon law, it’s not hard to see the pontiff’s point but the English archbishops soon issued their retaliatory Saepius officio, a highly technical piece, offering a kind of elaborate Tu quoque defense which did little except answer questions nobody had asked.  Almost a century later, the Anglicans offered another, admittedly more convincing but still legalistic, argument based on Anglican consecrations since the 1930s being co-performed by bishops recognized by Rome, so, given the effluxion of time, all Anglican bishops were now also in the old Catholic succession; Apostolicae curae, while not invalid, had been rendered obsolete by events, most obviously the bishops in dispute having by then dropped dead.

The view probably never had any chance of being accepted by the Holy See but the Anglicans’ ordination of women and embrace of gay clergy ended all discussion.  In 1998, Cardinal Ratzinger (1927–2022; pope 2005-2013, pope emeritus 2013-2022), head of the Congregation for the Doctrine of the Faith (the old Holy Office or Inquisition) issued a statement confirming Leo XIII’s view, adding ominously that anyone who denies such truths "... would be in a position of rejecting a truth of Catholic doctrine and would therefore no longer be in full communion with the Catholic Church".  There the matter has since rested.

Cardinal George Pell (1941-2023) places hands on the head of newly ordained bishop Peter Bryan Wells (b 1963; apostolic nuncio to South Africa and Botswana, apostolic nuncio to Lesotho and Namibiaand & titular Archbishop of Marcianopolis since 2016) of the United States.  St Peter's Basilica, the Vatican, 19 March 2016.

Cardinal Pell’s appointment as a bishop was in an unbroken chain of apostolic succession from the twelve apostles of Jesus; by touch, he’s able to add links to the chain.  Within the Roman Curia (a place of Masonic-like plotting & intrigue and much low skulduggery), Cardinal Pell's nickname was “Pell Pot”, an allusion to Pol Pot (1925–1998, dictator of communist Cambodia 1976-1979) who announced the start of his regime was “Year Zero” and all existing culture and tradition must completely be destroyed and replaced.

Equipoise

Equipoise (pronounced ee-kwuh-poiz or ek-wuh-poiz)

(1) An equal distribution of weight; even balance; equilibrium; The relation of two weights or forces which balance each other; equilibrium; equiponderance.

(2) An alternative name for a counterpoise in certain contexts, now rarely seen outside of literary and poetic use.

(3) In medical research, as clinical equipoise, or the principle of equipoise, a term to describe certain aspects of the ethical basis for clinical trials.

(4) In commercial pharmacy, the trademark for Hydroxyzine, an antihistamine and Boldenone Undecylenate, an anabolic steroid, once prescribed for human use, now restricted to veterinary applications, mostly equine.

(5) Of or pertaining to equilibrioception, the state of being balanced or in equilibrium.

1625–1635: An English coining which borrowed from both Latin and French, following the mid sixteenth century phrase "equal poise", the construct being equi + poise.  The prefix equi (which existed also as equ if preceding a vowel), was a word-forming element meaning "equal” from the Latin aequi, a combining form of aequus (equal, even).  Poise was from the Anglo-Norman poise (measure of weight), from the Anglo-Norman pois, from the Middle French pois (weight).

Clinical Equipoise

The term clinical equipoise, (also known within the medical research community as the principle of equipoise), was used first in 1987 by Benjamin Freedman (1951-1997), professor of medicine in the Biomedical Ethics Unit at McGill University, Montreal.  It provides a construct for the ethical framework of medical research involving the assignment of patients to different treatment streams in clinical trials.  An ethical dilemma exists in clinical trials if a researcher has cause to believe the treatment in one stream of a trial is significantly out-performing others.  Although it’s something of a deliberate scientific fiction, trials should be designed on the basis of a null hypothesis; that there should exist no evidence beyond the indicative that the intervention being trialed will result in better results than existing treatments or no treatment at all.  As a trial proceeds, findings may provide sufficient evidence to convince the investigator of the intervention’s efficacy and once a certain threshold of evidence is reached, uncertainty no longer exists, thereby creating an ethical imperative for the investigator to provide the superior intervention to all participants.  Being a thing applied to clinical work, it’s therefore not an abstract theory but, given the size, duration and complexity of many trials, it can be difficult to define exactly, or even vaguely, when the threshold has been reached.

Equipoise is one of the brand-names used for boldenone undecylenate (also as boldenone undecenoate.  It is an androgen and anabolic steroid (AAS) medication intended for use in in veterinary medicine (predominately equine) but in the 1970s it began to be used by humans, usually to enhance physical characteristics.  It remains available for veterinary use where it highly regarded but in most markets it's a controlled drug and use by humans is via the illicit market.
