Lambeth

Lambeth (pronounced lam-bith)

(1) A south London suburb, the location of Lambeth Palace, the seat of the Archbishop of Canterbury.

(2) A slang term for the hierarchy of the Church of England.

The name Lambeth embodies hithe, a Middle English word for a landing on the river.  Lambeth Palace has for some eight-hundred years been the official London residence of the Archbishop of Canterbury.  It sits on the south bank of the Thames, a quarter mile (400m) south-east of the Palace of Westminster, which contains the houses of parliament, on the opposite bank.

Rowan Williams (b 1950; Archbishop of Canterbury 2002-2012) and Benedict XVI (1927–2022; pope 2005-2013, pope emeritus 2013-2022) chat at Lambeth Palace.

The Lambeth Conference

The Lambeth Conference is a (nominally) decennial assembly of bishops of the Anglican Communion convened by the Archbishop of Canterbury.  There have been fourteen Lambeth Conferences, the first in 1867.  The Anglican Communion is an international association of autonomous national and regional churches, not a governing body and the office of Archbishop of Canterbury is in no way analogous with the Roman Catholic Pope.  The conferences serve a collaborative and consultative function and are said to express “…the mind of the communion" on issues of the day. Resolutions passed at a Lambeth Conference are without legal effect, but can be influential.

Conferences were never the pure and high-minded discussions of ethics, morality and theology some now appear to believe characterized the pre-modern (in this context those held prior to 1968) events.  Agenda and communiqués from all conferences have always included the procedural, administrative and jurisdictional although in recent years, they’ve certainly reflected an increasingly factionalized communion rent with cross-cutting cleavages, first over the ordination of women and of late, homosexual clergy.  During the 1998 conference, Bishop Chukwuma (b 1954) of Nigeria attempted to exorcise "homosexual demons" from the soul of Nigerian-born Richard Kirker (b 1951), a British priest and general secretary of the Lesbian and Gay Christian Movement.  Recalling probably Ephesians 4:32 or perhaps the more cautionary Matthew 6:15, Kirker forgave him.

The spirit of Kirker notwithstanding, at this point, the disagreements seem insoluble.  The poisonous atmosphere at, and in the aftermath of, the last conference in 2008 did not enhance the image of the church and a typically Anglican solution to avoid a repetition in 2018 seemed to have emerged.  In 2014, in answer to the suggestion he had cancelled the 2018 conference, Archbishop Justin Welby (b 1956; 105th Archbishop of Canterbury 2013-), in a statement worthy of any of his predecessors, responded by stating, "As it hasn’t been called, it can’t have been cancelled."

A communiqué issued after the primates' meeting in January 2016, noted the bishops had accepted the archbishop’s proposal the fifteenth conference should be held in 2020.  However, because of the COVID-19 pandemic, it was in March 2020 decided to postpone the conference to the summer of 2021 but the virus proved elusive and by July, the delay had been extended to 2022.  The first epistle of Peter has been chosen as the biblical focus for the conference, the theme of which is said to be what it means to be “God’s Church for God’s World”.  The apostle Peter wrote this epistle to give comfort to Christians suffering persecution from non-believers, hoping to encourage them to live pure lives despite their vicissitudes.

Peter didn’t sugar-coat the message (1 Peter 4:12-19), making it clear that for Christians, suffering is actually a participation in the sufferings of Christ and is an occasion for rejoicing, helpfully adding that in the midst of the suffering, the Holy Spirit rests upon those who are suffering, this being a great consolation.  He further explains that God uses suffering to purify the Christian community, God's household.  God uses the abuse that pagans unjustly heap on Christians to prepare his people for the return of Christ and warns people not to be surprised at the fiery ordeal that will come upon them as followers of Jesus.  Actually, they should be both grateful and happy and thus glorify God, for if they share in Christ’s sufferings it means they will also share in his glory.

In a world beset by fire, flood, pestilence and plague, 1 Peter seems a good theme to loom over a Lambeth Conference.  Whether or not Christians beyond the Kent conference rooms will long note the message, it probably will resonate with Archbishop Welby’s predecessor, Rowan Williams (Baron Williams of Oystermouth, b 1950; 104th Archbishop of Canterbury, 2002-2012).  During his tenure at Lambeth, Dr Williams probably felt more ignored than persecuted by non-believers, finding the internecine squabbles of the believers in the Anglican factions rather more tiresome.  Declaring the problems in the church “insoluble” he seemed not unhappy to be leaving Lambeth to return to his study and write about Dostoevsky.  A generous spirit, he will have wished his successor well.

Cesspool & Cesspit

Cesspool (pronounced ses-pool)

(1) A cistern, or sump for the temporary retention of the sediment of a drain or for receiving the sewage or waste-water from a house or other building; also called a sink.

(2) As a casual description, any filthy receptacle or place.

(3) By extension, any place of corruption, iniquity, moral filth, depravity or immorality:

1670s: From the early Modern English cess-pool & sesspool (cistern or well to receive sediment or filth).  The origin is (perhaps expectedly) murky.  It may be from the Italian cesso (privy) from the Latin secessus & rēcessusrecess (“place of retirement” and, in Late Latin "privy or drain") documented in English since the 1580s.  It seems convincing because the dialectal form was suspool, from suss & soss (puddle; mire) or cess (a bog on the banks of a tidal river).  Another theory of the seventeenth century shift involves the influence of the French cesperalle, an alteration of the Middle English suspiral, from the Old & Middle French souspirail (air hole; a vent for air) from soupirer & souspirer (to sigh, breathe), from the Latin suspirare.  Other speculation is it may have been either an alteration of cistern or a shortened form of recess or the whole may be an alteration of the (circa 1400) suspiral (drainpipe), from the Old French sospiral (a vent, air hole) from sospirer (breathe) from the Latin suspirare (breathe deep).  The fact the meaning extended to "tank at the end of the pipe," does make plausible a possible folk-etymology change in final syllable.  Gongpit was the most attractive of the nicknames, most of the others predictably more overtly scatological.

Pool is from the Middle English pool, pole & pol, from the Old English pōl (pool), from the Proto-Germanic pōlaz (pool, pond), from the primitive Indo-European bōlos (bog, marsh).  It was cognate with the Scots puil (pool), the Saterland Frisian Pol (pool), the West Frisian poel (pool), the Dutch poel (pool), the Low German Pohl & Pul (pool), the German Pfuhl (quagmire, mudhole), the Danish pøl (puddle), the Swedish pöl (puddle, pool), the Icelandic pollur (puddle), the Lithuanian bala (bog, marsh, swamp, pool), the Latvian bala (a muddy, treeless depression), the Russian боло́то (bolóto) (swamp, bog, marsh).

Cesspit (pronounced ses-pit)

(1) A pit for the temporary retention of the sediment of a drain or for receiving the sewage or waste-water from a house or other building; also called a sink.

(2) As a casual description, any filthy receptacle or place.

(3) By extension, any place of corruption, iniquity, moral filth, depravity or immorality:

1860–1865, the construct being cess + pit.  Pit is pre-900, from the Middle English pit, pet & püt, from the Old English pytt, from Proto-West Germanic puti, from the Latin puteus (trench, shaft, pit, well), the verb derivative of the noun; that seems the consensus although many etymologists note the some phonetic inconsistencies.  The unrelated use as a verb, as pit, pitted, pitting in the sense of removing the pit from a fruit or fruits is an Americanism from 1835-1845, influenced both by pith and the Dutch kernel.

Cesspits, cesspools, and the swamp

A cesspit.

In modern plumbing, cesspits, cesspools and septic tanks are alike in construction, none being connected to a main sewer system, the difference being cesspools and cesspits do not include a treatment system.  Pre-war English legislation best illustrates the difference between cesspits and cesspools which, prior to the Public Health Act (1936), were different things.  Cesspits resembled wells, circular brick chambers built about 6 feet (1.8m) deep in the ground, acting like a soakaway.  The design was flawed because the drains would eventually back up so the Public Health Act prohibited the use of cesspits, requiring other drainage methods to be used so after 1936, only cesspools and septic tanks were installed but, other than professional plumbers or public health specialists, few noticed or cared much to explore the difference so, among the public, cesspit and cesspool came to be used interchangeably and thought to mean much the same thing.

A cesspool.

A modern cesspool is a watertight, fibreglass storage tank which holds sewage and is stored underground in a pit. It does not have an outlet or any apparatus to carry out any treatment process, the only piping being that connect to a relief valve which prevents any build-up of hazardous gasses.  Cesspools thus demand regular emptying by a licensed waste disposal company, which is why they’re now usually only a temporary solution.  The frequency with which they must be emptied differs and is predictably dictated by the variables: the size of the tank, and the volume of material it receives, calculations based usually on the number of people serviced by the unit.  Cesspools are normally used in locations which don’t have access to mains drainage, holiday homes, camp sites and places where the discharge of effluent into the ground is not possible because of unsuitable soil.  Although not always required by local ordinances, cesspits should be fitted with an alarm that notifies when the tank is approaching capacity, manufacturers caution it’s not advised to open the lid to check the level because noxious gasses will be emitted, unpleasant at least and potentially hazardous if inhaled.

A septic tank.

A septic tank is similar to a cesspit, the tank construction almost identical and also installed underground and not connected to a main sewer system.  Where a septic tank differs is in being a component of a sewage treatment system where the wastewater, or effluent, drains into a soakaway after treatment.  The tank has two or three chambers which separate waste into liquids and solids, and then the liquids (effluent) move through an outlet into a soakaway chamber or drainage system.  A soakaway, known also as a drainage field, is a system of piping which is designed to spread liquids evenly into the surrounding soil.  To avoid blockages, septic tanks need annually to be emptied of the residual solid waste, again a task which should be undertaken only by a professional.  In the modern, urban environment, cesspools should really be regarded a temporary device because they’re not only expensive to maintain bur are a potential contaminant as untreated effluent can overflow into the surrounding environment. Septic tanks have a treatment system and are thus safer but are still a compromise and the most economic and convenient option is, wherever possible, connect to a mains system.

Washington Post, 13 December 2016.

Because of the stench and squalor summoned by the imagination whenever the words cesspit and cesspool are mentioned, they’ve long been a favorite piece of imagery when speaking of corrupt or morally bankrupt assemblies of politicians or other self-interested souls.  Despite the technical differences in the plumbing arrangements, when used figuratively, cesspool and cesspit are interchangeable, the choice depending only on which best suits the rhythm of the sentence in which it appears.  Both describe a place hidden from view where sewage gathers, a pool full of nastiness, a place swimming with grubs and corruption.  The attraction of using it when speaking of politics is obvious but Donald Trump (b 1946; US president 2017-2021), in the 2016 presidential campaign instead choose the catchy phrase “drain the swamp” to express much the same idea.  When in office, there was scant evidence of any drainage although he certainly took the opportunity to toss into the swamp a few creatures of his choice.  He did at least mention the problem, something which few professional politicians have ever been interested in doing but the swamp-like nature of electoral politics is a product of incumbency and the more prolonged the longevity, the greater the opportunity further to rig the system to gain even more time in the swamp while gorging at the trough (an unfortunate mix of metaphors but a vivid image).  The core value of democracy is the election but perhaps its most corrupting aspect is the re-election.  Were term limits introduced, preferably as single terms of a reasonable length, perhaps four years, one of the great drivers of political corruption would be removed.  It should be assumed this will never be done.

The notion of Donald Trump cleaning up the cesspool of corruption in politics was one idea.  There have been other suggestions. 

Cabotage

Cabotage (pronounced kab-uh-tij or kab-uh-tahzh)

(1) In seafaring, navigation or trade along the coast.

(2) In aviation, the legal restriction to domestic carriers of air transport between points within a country's borders (with certain exceptions).

(3) The transport of goods or passengers between two points in the same country; the exclusive right of a country to control such transport.

(4) In law, the right to engage in such transport.

1825–1835: A borrowing from the French cabotage (coasting trade) from the French caboter (to sail coastwise; to travel by the coast), a verbal derivative of the Middle French cabo & the Spanish cabo (headland; cape).  Ultimate root is the Latin caput (head).  Word was first used in sixteenth century France to reference the restrictions which permitted only French ships to trade or transport between French ports. Other countries adopted the concept, later extending it to land and air travel.  Cabotage is a noun; the noun plural is cabotages.

Rights

Example of a cabotage arrangement.

Originally a term applied exclusively to shipping along coastal routes, cabotage can now refer also to aviation and land transport.  It is the transport of passengers and/or goods between two places in one country, undertaken by vessels from a different country.  Cabotage rights are those which define the extent to which transport operators from one country can trade in another and many arrangements exist.  In aviation, it is the right to operate within the domestic borders of another country; most states don’t permit aviation cabotage, and strict sanctions exist, historically either for reasons of economic protectionism, national security, or public safety.  One exception is the European Union, the member states of which grant cross-vested rights to all others, cabotage rights remaining otherwise rare in passenger aviation.  The Chicago Convention on Civil Aviation prohibits member states from granting cabotage on an exclusive basis, which has meant it’s not been used in bilateral aviation negotiations and is not granted under most open skies agreements.  The Closer Economic Relations agreement between Australia and New Zealand permits Australian carriers to fly domestically and internationally from New Zealand and vice versa. Additionally, there are limited rights for the airlines to service domestic routes within both countries.

Hangry

Hangry (pronounced hang-gree)

Feeling irritable or irrationally angry because of hunger.

1915-1920: A portmanteau word, the construct being from h(ungry) + angry.  Hungry is from the Middle English hungry, from the Old English hungriġ & hungreġ (hungry; famishing; meager), from the Proto-Germanic hungragaz (hungry).  It was cognate with the Dutch hongerig, the German hungrig and the Swedish hungrig, all of which meant “hungry”.  Anger is from the Old Norse angr (affliction, sorrow).

Hungry (pre 950) was from the Middle English hungry & hungri, from the Old English hungriġ & hungreġ (hungry; famishing; meager) which existed also in the Common West Germanic and was from the Proto-Germanic hungragaz (hungry).  It was cognate with the German hungrig, the Old Frisian hungerig, the Dutch hongerig, the German hungrig and the Swedish hungrig, all of which meant “hungry”.  The use as a figurative form is noted from circa 1200.

Angry (1350-1400) in the sense of "hot-tempered, irascible; incensed, openly wrathful" is a construct of the earlier noun anger + -y,  The Old Norse adjective was ongrfullr (sorrowful) (the Old Norse angr meant “affliction, sorrow”), from the mid thirteenth century a Middle English form was angerful (anxious, eager).  The “angry young man” dates from 1941 but became a popular form only after John Osborne's (1929-1994) play Look Back in Anger was performed in 1956 although the exact phrase does appears nowhere in the text.  The rare related form is angriness.

The –y suffix is from the Middle English –y & -i, from the Old English -iġ (-y, -ic), from the Proto-Germanic -īgaz (-y, -ic), from the primitive Indo-European -kos, -ikos, & -iḱos (-y, -ic).  It was cognate with the Scots -ie (-y), the West Frisian -ich (-y), the Dutch -ig (-y), the Low German -ig (-y), the German -ig (-y), the Swedish -ig (-y), the Latin -icus (-y, -ic) and the Ancient Greek -ικός (-ikós); a doublet of -ic.  The –y suffix was added to (1) nouns and adjectives to form adjectives meaning “having the quality of” and (2) verbs to form adjectives meaning "inclined to".

The cats Hillary & Bill: a question understandably frequent in some marriages.

Etymologists list hangry as a humorous invention in US English dating from circa 1915-1920 but use soon died out, not to be revived until 1956 when it was mentioned in the US psychoanalytic journal American Imago in a discussion about various kinds of deliberate and accidental wordplay.  Hangry, unlike some of contractions or elisions documented, survived (or was again revived) in the internet age, becoming popular from the mid-1990s and achieved sufficient linguistic critical-mass for the Oxford English Dictionary (OED) to accept it as a word in their 2018 update.  Even among those who dismiss hangry as slang, the usual rules of English should apply so the comparative is more hangry, the superlative most hangry, and the adjectives hangrier and hangriest.

Hangriness can lead to "diva-like behavior".  The Australian New Idea is a "women's magazine" offered still in a print edition as well as on-line.  Locally, the slang for the publication is "The No Idea".

Some dictionaries still resist, apparently not convinced it’s yet a proper word despite the usually authoritative imprimatur of the OED.  For those who side with the OED, of note is that hangry thus becomes only the third word in English to end in –gry, the other two being, predictably, angry and hungry.  There is the odd instance in the historic record of puggry (a light scarf wound around a hat or helmet to protect the head from the sun) but etymologists overwhelmingly say this is a mistake, a Raj-era corruption of the correct puggaree, from the Hindi, Urdu and Punjabi pagṛī (turban), related to the Punjabi pagg (turban) and Kashmiri pag (turban), all of unknown origin.  Angry, hungry & hangry are the only words in English ending in "gry". 

Solecism

Solecism (pronounced sol-uh-siz-uhm or soh-luh-siz-uhm)

(1) In language, a non-standard or ungrammatical usage.

(2) A breach of good manners or etiquette.

(3) Any error, impropriety, absurdity or inconsistency.

1570-1580: From the Latin soloecismus, from the Greek soloikismos, from soloikos (speaking incorrectly), the construct being Sólo(i) + -ic (from the Middle English -ik, from the Old French -ique, from the Latin -icus, from the primitive Indo-European -kos, formed with the i-stem suffix -i- and the adjectival suffix –kos.  The Ancient Greek form was -ικός (-ikós), the Sanskrit श (śa), क (ka) and the Old Church Slavonic -ъкъ (-ŭkŭ); doublet of –y; on noun stems, it carried the meaning “characteristic of, like, typical, pertaining to” and on adjectival stems, it acted emphatically) + -ism (ultimately from either the Ancient Greek -ισμός (-ismós), a suffix that forms abstract nouns of action, state, condition, doctrine; from stem of verbs in -ίζειν (-ízein) (from which English gained -ize), or from the related suffix Ancient Greek -ισμα (-isma), which more specifically expressed a finished act or thing done).  Solecism & solecist are nouns, solecistic & solecistical are adjectives and solecistically is an adverb; the noun plural is solecisms.

A solecism in sandals & socks.

The meaning "gross grammatical error" or "any absurdity or incongruity" dates from the 1570s, a borrowing directly from the sixteenth century Middle French solécisme which came from the Latin soloecismus (mistake in speaking or writing), which gained the word from the Greek soloikismos (to speak (Greek) incorrectly), from soloikos (an ungrammatical utterance), the literal translation of which was "speaking like the people of Sóloi, an Athenian colony in Cilicia (Mezitli in the modern-day Republic of Türkiye), whose dialect, a corrupt form of Attic Greek, Athenians considered barbarous.  The English, perhaps predictably, later extended the meaning to matters of etiquette, thus the sense of “awkward or rude in manners” and, by the late twentieth century, sins against fashion and good taste.

A solecism in blusher: Lindsay Lohan in court, Los Angeles October 2011.

The zombie-like look presumably wasn't intentional and it attracted some comment from professional make-up techs.  Speculation about how this happened ranged from the blusher being applied (1) in less than ideal lighting conditions, (2) in a car with only the rear-vision mirror available and (3) with bare fingers because a brush couldn't be found.  The consensus was the goal was a contoured blush look which, if applied with some delicacy, can accentuate the cheekbones but this was heavy handed and ended up as a smear across the cheeks.

Baryon

Baryon (pronounced bar-ee-on)

(1) In physics, a proton, neutron, or any elementary particle that decays into a set of particles that includes a proton; any of a class of elementary particles that have a mass greater than or equal to that of the proton, participate in strong interactions, and have a spin of 1/2 . Baryons are either nucleons or hyperons. The baryon number (baryogensis) is the number of baryons in a system minus the number of antibaryons.

(2) In astronomy, a specific description for objects in the universe composed of conventional atomic matter.

1950–1955: From the Ancient Greek βαρύς (barús & barý(s)) (heavy) +‎ -on (the Ancient Greek -ον (-on) suffix ending neuter nouns and adjectives).  The word was coined by Dutch-American physicist Abraham Pais (1918–2000) and chosen because at the time, most known elementary particles had lower masses than baryons. Baryons are significant in cosmology because the standard model assumes the Big Bang produced a state with equal amounts of baryons and antibaryons.  Baryon is a noun & baryonic is an adjective; the noun plural is baryons.

Of matter

For experts only: The baryon number.

By definition, baryonic matter should only include matter composed of baryons. It should include protons, neutrons and all the objects composed of them (ie atomic nuclei), but exclude things such as electrons and neutrinos which are actually leptons.  Astronomers however apply the term ‘baryonic matter’ rather more liberally, arguing that on astronomical scales, protons and neutrons are always accompanied by electrons (in appropriate numbers for astronomical objects to possess all but zero net charge).  Astronomers therefore use ‘baryonic’ to refer to all objects made of normal atomic matter, essentially ignoring the presence of electrons (which represent less than 0.0005% of the mass).  Neutrinos, on the other hand, are considered non-baryonic by astronomers and physicists alike.  Another of astronomy’s quirks is that black holes are often included as baryonic matter although physicists insist that while most of the matter from which black holes form is baryonic matter, once swallowed by the black hole, this distinction is lost and, although still subject to speculation, the current orthodoxy is that black holes cannot possess properties such as baryonic or non-baryonic.  Objects of baryonic matter include clouds of cold gas, planets, comets, asteroids, stars, neutron stars and (possibly) black holes.  Non-baryonic matter includes neutrinos, free electrons, dark matter, supersymmetric particles, axions, and (possibly) black holes.

Dimorphous

Dimorphous (pronounced dahy-mawr-fuhs)

(1) Occurring or existing in two different forms.

(2) In botany, plants with roots with two distinctive forms for two separate functions.

(3) In botany, as frond dimorphism, differing forms of fern fronds between the sterile and fertile fronds.

(4) In botany, as dimorphic fungi, fungi which can exist as both mold and yeast.

(5) In cell biology, as phenotypic dimorphism, a switching between two or more cellular morphologies.

(6) In zoology, a phenotypic difference between males and females of the same species.

(7) In nuclear physics, a cell where the nuclear apparatus is composed of two structurally and functionally differentiated types of nuclei.

(8) In geology, the property of some substances to exist in two distinct crystalline forms.

1801: From the Ancient Greek dímorphos (of two forms), the construct being di + morphē (form, shape).  The suffix di- was from the Ancient Greek δῐ- (di-), from δῐά (diá) (through), from the Latin di- (two, twice or double (the synonyms were duo-, bi- & bis-)) and was an alternative form of dis-, shortened when placed before l, m, n, r, s (followed by a consonant), and v; it was also often shortened before g, and sometimes before j.  Morphe was a back-formation from morpheme, from the Ancient Greek μορφή (morphḗ) (form, shape); the similar German Morph is from morphem and attested since the 1940s.  In formal grammar and structural linguistics, morphe is a physical form representing some morpheme in language; a recurrent distinctive sound or sequence of sounds.  In linguistics, an allomorph is one of a set of realizations that a morpheme can have in different contexts.  The –ous suffix is from the Middle English -ous, from the Old French –ous & -eux, from the Latin -ōsus (full, full of); a doublet of -ose in an unstressed position.  It was used to form adjectives from nouns, to denote possession or presence of a quality in any degree, commonly in abundance.  In chemistry, it has a specific technical application, used in the nomenclature to name chemical compounds in which a specified chemical element has a lower oxidation number than in the equivalent compound whose name ends in the suffix -ic.  For example sulphuric acid (H₂SO₄) has more oxygen atoms per molecule than sulphurous acid (H₂SO₃).  The class of words to which dimorphous belongs originally was most often used in botany to describe plants with one (monœcious), two (diœcious) or there (trimorphic) forms.  Dimorphous & dimorphic are adjectives, dimorphism is a noun and dimorphically is an adverb; the noun plural is dimorphisms.

The asteroid Dimorphos compared with the Colosseum in Rome.

First observed in 2003, Dimorphos is a small asteroid, technically a minor-planet moon of a synchronous binary system, Didymos, discovered in 1996, the primary asteroid.  Unfortunately, after the usual committee processes of the Working Group Small Body Nomenclature (WGSBN) of the International Astronomical Union (IAU), the astronomers’ preferred nickname "Didymoon" was declined, the official name Dimorphos granted on 23 June 2020.  With a diameter of 170 metres (560 feet), it’s among the smallest astronomical objects to be given a permanent name.

The LICIACube.

Dimorphos is of greater interest than most asteroids because it’s the target of NASA's Double Asteroid Redirection Test (DART) mission, the impact scheduled for 26 Sep 2022.  The DART project is a proof-of-concept mission to test the viability of using small-scale physical impacts as a means to divert the trajectory of asteroids or other objects likely to hit Earth.  The DART process too is dimorphous and only partially self-destructive, the European Space Agency’s (ESA) Light Italian CubeSat for Imaging Asteroids (LICIACube) travelling attached to the doomed projectile, separating ten days before impact, that mission to observe and record the impact’s consequences.  Although about the size of a small car, with the solar panel wings unfurled, DART is as big as a 32-40 seat bus while LICIACube, equipped with the LICIACube Unit Key Explorer (LUKE) and LICIACube Explorer Imaging for Asteroid (LEIA) optical cameras is a small package with a mass of about 30 pounds (14 kilograms), barely bigger than a respectable handbag.  The size and weight of the ESA’s equipment was dictated by the limits imposed by the need to restrict the volume to what could be carried by DART for the entire journey.

DART with its solar panel wings unfurled.

The name, derived from the Ancient Greek Dimorphos (having two forms) refers not to what the unsuspecting rock is but what it will become, the second of its forms emerging after DART strikes.  Dimorphos will become the first celestial body in history, the form of which will substantially be changed by human intervention and this may therefore be something unique in the universe.  The point of the experiment is to determine if impacts at speed (and therefore of greater energy, DART planned to hit at 15,000 mph (24,100 km/h)) by small objects is sufficient to deflect objects by enough to change their course.  The theory is that if undertaken at long-distance, only a tiny change in trajectory should be enough to avert an object from a collusion path with Earth.  NASA launched DART on 24 November 2021.

Point of DART and LICIA separation.

Ten days before DART strikes Dimorphos, LICIACube will be released, firing its thrusters to separate from the mother-ship, then positioning itself to be at the correct angle to optimize the viewing window while ensuring it’s remains at a distance close enough to capture the desired details yet not so close as to risk damage from whatever debris the impact may eject.  The DART images immediately prior to impact will actually be a real-time stream; travelling at the speed of light, the data will take some 38 seconds to travel the 6.8 million miles (10.9 million km) to Earth.  LICIACube will store the data and continually transmit images in the months after DART’s demise. 

DART Mission plan.

Although the target asteroid is tiny compared to the cataclysmic Chicxulub behemoth which struck Earth 66 million years ago, ending the long age of the dinosaurs, the data derived from the DART experiment should be robust enough to be scalable and mathematical models will be developed to work out how much energy will need to be deployed to gain the desired effect, hence the often speculated use of nuclear explosions if the troublesome rock is really big.  Asteroids, primordial rocky remnants from the solar system’s formation some 4.6 billion years, are not uncommon and some are already on a path to strike earth sometime during the next few million years so the threat is real, even if the timing is unpredictable.

One flavor of the dimorphic role: Lindsay Lohan in The Parent Trap (1998).

In fictional depictions, well known examples of dimorphic roles include (1) the one individual manifesting in two very different forms such as the protagonist(s) in Robert Louis Stevenson's (1850–1894) Strange Case of Dr Jekyll and Mr Hyde (1886), (2) one which explores aspects of duality which manifest as two characters with lives or personalities intertwined to the extent that the distinction between the two is sometimes lost (Waiting for Godot (1953) by Samuel Beckett (1906-1989)) or used as a literary device (The End of the Affair (1951) by Graham Greene (1904-1991)) & (3) the one actor playing two different characters who are in some way closely related or associated (Lindsay Lohan in The Parent Trap (1998)).  However, where an actor plays two quite distinct roles (Peter Sellers (1925–1980) in Dr Strangelove (1964) although he actually played three) this is not thought dimorphic because the characters are connected except through the device of the plot.

Choleric

Choleric (pronounced kol-er-ik or kuh-ler-ik)

(1) Extremely irritable or easily angered; irascible; bad-tempered.

(2) A person with a choleric temperament.

(3) A person suffering from the infectious disease cholera (rare).

1300–1350: From the Middle English colrik & colerik (bilious of temperament or complexion), from the Old French colerique, from the Medieval Latin colericus (bilious), from the Classical Latin cholericus, from the Ancient Greek cholerikós or kholerikós, from the Greek kholera (a type of disease characterized by diarrhea, supposedly caused by bile), from khole (gall, bile) and so-called for its color, related to khloazein (to be green) & khlōros (pale green, greenish-yellow), from the primitive Indo-European root ghel- (to shine), with derivatives denoting "green, yellow," and thus "bile, gall”.  The meaning "easily angered, hot-tempered" is from 1580s (based on the then-current medical orthodoxy of the supposed effect of excess choler) and the synonyms include wrathful, testy, impatient, touchy, bilious, irascible and peevish.  The more literal use "of or pertaining to cholera" dates only from 1834.  Choleric is a noun & adjective, cholerically & cholericly are adverbs and cholericness is a noun; the noun plural is cholerics.

Many have choleric moments; there are good days and bad days.

It was an excess of the humor of yellow bile (xanthe chole) which made one choleric.  Humoral (humor a translation of the Ancient Greek χυμός (chymos (literally juice or sap, figuratively flavor)) theory (known also as humorism or humoralism), was a system of medicine from antiquity which provided a framework and description of the supposed workings of the human body.  It was the standard model for the philosophers and physicians of Ancient Greek and Rome and endured in Western medicine well into the nineteenth century when many of its assumptions about physical illness were disproved by germ theory and the understanding of the role of pathogens in disease.  The overturning of humoral theory was one of the landmarks in the origins of modernity.

In antiquity it was a concept rather than something with a standardized systemization and there existed competing models with more or fewer components but it’s because the description with four was that endorsed by the Greek physician Hippocrates (circa 460–circa 370 BC) that it became famous in the West and absorbed into medical practice.  The four humors of Hippocratic medicine are black bile (μέλαινα χολή (melaina chole)), yellow bile (ξανθη χολή (xanthe chole)), phlegm (φλέγμα (phlegma)) & blood (αἷμα (haima)), each corresponding with the four temperaments of man and linked also to the four seasons: yellow bile=summer, black bile=autumn, phlegm=winter & blood=spring.  In Hippocratic medicine, to be healthy, the four humors needed to be in balance and this, once achieved, was the state of enkrateia (from the Ancient Greek ἐγκράτεια (eukrasia) (in power), the construct being ἐν (en-) (in-) + κράτος (krátos) (power), a word which appears in the New Testament in the context of virtues (Acts 24:25, Galatians 5:23 & 2 Peter 1:6).  In the King James Version (KJV, 1611), it would be translated as "temperance", a word which went on to assume a life of its own.

Spectrum condition: The redness in the face of Barnaby Joyce (b 1967; thrice deputy prime minister of Australia 2016-2021) is used by his colleagues to gauge where his state of mind lies in the adjectival progression of the choleric (left), the more choleric (comparative; centre) and the most choleric (superlative; right).  Mr Joyce’s symptoms (ambitious, leader-like, restless, easily angered) suggest an excess of yellow bile and to counteract this, Hippocrates recommended cold and wet foods such as cucumber or lettuce to bring the humors back into alignment.  Mr Joyce should adopt a cucumber & lettuce diet.

Inflammable & Flammable

Inflammable (pronounced in-flam-uh-buhl)

(1) Easily set on fire; combustible; incendiary, combustible, inflammable, burnable, ignitable (recommended only for figurative use).

(2) Easily aroused or excited, as to passion or anger; irascible; fiery; volatile, choleric.

1595–1605: From the Medieval Latin inflammābilis, the construct being the Classical Latin inflammā(re) (to set on fire) + -bilis (from the Proto-Italic -ðlis, from the primitive Indo-European i-stem form -dhli- of -dhlom (instrumental suffix).  Akin to –bulum, the suffix -bilis is added to a verb to form an adjectival noun of relationship to that verb (indicating a capacity or worth of being acted upon).  Construct of the Classical Latin inflammare (to set on fire) is -in (in, on) + flamma (flame).

Flammable (pronounced flam-uh-buhl)

Easily set on fire; combustible; incendiary, combustible, inflammable, burnable, ignitable

1805–1815: From the Classical Latin flammā(re) (to set on fire) + -ble (the Latin suffix forming adjectives and means “capable or worthy of”).

Need for standardization

Flammable and inflammable mean the same thing.  English, a mongrel vacuum-cleaner of a language, has many anomalies born of the haphazard adoption of words from other tongues but the interchangeability of flammable and inflammable is unfortunate because of the use in signs to warn people of potentially fatal danger.

In- is often used as a prefix with adjectives and nouns to indicate the opposite of the word it precedes (eg inaction, indecisive, inexpensive etc).  Given that, it’s reasonable to assume inflammable is the opposite of flammable and that objects and substances should be so-labeled.  The reason for the potentially deadly duplication is historic.  Inflammable actually pre-dates flammable, the word derived from the Latin verb inflammare (to set on fire), this verb also the origin of the modern meaning “to swell or to provoke angry feelings”, hence the link between setting something on fire and rousing strong feelings in someone.  So, at a time when Latin was more influential, inflammable made sense.  However, as the pull of Latin receded, words with in- (as a negative prefix) became a bigger part of the lexicon and the confusion was created.  By the early nineteenth century, flammable had become common usage, and by the twentieth was widespread.  The modern convention is to use flammable literally (to refer to things which catch fire) and inflammable figuratively (to describe the arousal of passions, the swelling of tissue etc.  Surprisingly, the rules applying to warning signs have yet to adopt this standardization.

Using flammable and inflammable to mean the same thing is confusing.  The preferred wording is flammable and non-flammable.  Borrowing from semiotics, danger should be indicated with red, safety with green.
