Chiaroscuro

Chiaroscuro (pronounced kee-ahr-uh-skyoo-roh)

(1) The distribution of light and shade in a picture.

(2) In painting, the use of deep variations in and subtle gradations of light and shade in color, especially to enhance the delineation of character and for general dramatic effect.

(3) In monochrome painting, using light and dark only, as in the grisaille technique.

(4) The artistic distribution of light and dark masses in images.

(5) A woodcut print in which the colors are produced by the use of different blocks with different colors.

(6) A sketch in light and shade.

1680-1690: From the Italian chiaroscuro (disposition of light and dark in a picture (literally "bright-dark"), the construct being chiaro (clear, bright) from the Latin clārus ((clear, bright, renowned, famous, illustrious)) + oscuro (dark) from the Latin obscūrus (dark, dusky, shadowy, indistinct, unintelligible, obscure, intricate, involved, complicated, unknown, unrecognized; (of character) reserved, secret, close). Related forms are the nouns chiaroscurist and chiaroscurism.  The seventeenth century Italian forms were chiaroclear and oscuroobscure.  Chiaroscuro is a noun & adjective, chiaroscurist is a noun and chiaroscuroed is an adjective; the noun plural is chiaroscuros or chiaroscuri.

In oil painting, the technique of Chiaroscuro emerged during the Renaissance.  Essentially, it aimed to create the optical illusion of three-dimensional forms by emphasizing the tonal contrasts between light and dark. It’s a clever artistic trick achieved by having light fall against the edges of solid, darker forms and the most celebrated exponents were Leonardo da Vinci, Caravaggio, and Rembrandt.

Now less fashionable in painting, probably because modern artists are understandably not anxious to seek comparison with old masters, it’s perhaps the dominant technique in photography and when working in monochrome, it can produce fine results.  Called the Rembrandt technique or Rembrandt lighting, it’s also been occasionally adopted by film directors although it’s difficult to execute and ultimately renders a product not at all realistic which sometimes can be the director’s intent; sometimes perhaps not.  In the case of some Soviet cinema, the technique was adopted and is considered a distinctive element in many works in the genre of "socialist realism" although that is something quite distinct from "appearing realistic".  Soviet art was riddled with such paradoxes.

Paris-based Bulgarian photographer Elina Kechichevna (b 1979) created Dior’s 2021 Spring Summer collection (SS21) campaign, emulating Caravaggio’s (1571-1610) masterful handling of the technique of chiaroscuro.  Thematically, Kechichevna explored a number of strands including feminist thought, romanticism and the interplay of chiaroscuro’s layering of light with tricks of geometry in placement.

Deliquesce

Deliquesce (pronounced del-i-kwes)

(1) In physical chemistry, to become liquid by absorbing moisture from the atmosphere and dissolving in it (best illustrated by the behavior of certain salts).

(2) To melt away; to disappear (used literally & figuratively).

(3) In botany, branching so the stem is lost in branches (as is typical in deciduous trees).

(4) In mycology (of the fruiting body of a fungus), becoming liquid as a phase of its life cycle.

1756: From the Latin dēliquēscere (to become liquid), the construct being dē- + liquēscere (to liquefy; liquescent).  In scientific literature, the adjective deliquescent (liquefying in air) is the most commonly used form.  It was from the Latin deliquescentem (nominative deliquescens), present participle of deliquescere (to melt away), the construct being de- + liquesco (I melt) and familiar in French also as déliquescent.  The de- prefix was from the Latin dē-, from the preposition dē (of, from (the Old English æf- was a similar prefix).  It imparted the sense of (1) reversal, undoing, removing, (2) intensification and (3) from, off.  In French the dé- prefix was used to make antonyms (as un- & dis- function in English) and was partially inherited from the Old and Middle French des-, from the Latin dis- (part), the ultimate source being the primitive Indo-European dwís and partially borrowed from Latin dē-.  The figurative sense of “apt to dissolve or melt away” was in use by 1837 while the verb deliquesce appears not to have been used thus until the late 1850s.  In scientific literature, the adjective deliquescent (liquefying in air) is the most commonly used form.  It was from the Latin deliquescentem (nominative deliquescens), present participle of deliquescere (to melt away), the construct being de- + liquesco (I melt) and familiar in French also as déliquescent.  The figurative sense of “apt to dissolve or melt away” was in use by 1837 while the verb deliquesce appears not to have been used thus until the late 1850s.    Deliquesce, deliquesced & deliquescing are verbs, deliquescent is an adjective, deliquescence is a noun and deliquescently is an adverb; the noun plural is deliquescences.

Deliquesce 1, oil on canvas by Tammy Flynn Seybold (b 1966).

This was the first in the Deliquesce Series, a group of works exploring the themes of transformation and conservation of energy in human forms, the artist noting being intrigued by the deceptively ephemeral nature of materials: “We think of objects - human forms included - as decaying, degrading or ‘disappearing’ but, as we know from the laws of thermodynamics, all energy is conserved - like matter, it is merely transformed from one form to another.  This work, painted with pastel-hued oils was made directly from a live model, the drips allowed organically to happen from her languid form and by using light, bright hues, I hoped to bring a spirit of optimism to this transformative process.”

A footnote to the addition of deliquesce to scientific English is a tale of the chance intersection of politics and chemistry.  Dr Charles Lucas (1713–1771) was an Anglo-Irish physician who held the seat of Dublin City in the Irish Parliament and was what now would be called “a radical”, dubbed at the time “Irish Wilkes” (a nod to the English radical politician John Wilkes (1725–1797).  His early career was as an apothecary and he was shocked discover the fraud and corruption which permeated the industry and in an attempt to reform the abuses published A Short Scheme for Preventing Frauds and Abuses in Pharmacy (1735) which much upset his fellow apothecaries who were the beneficiaries of the crooked ways but the parliament did respond and created legislation regulating standards in medicines and providing for the inspection of the products; it was the first of its kind in the English-speaking world and the ancestor of the elaborate framework of rules today administered by entities such as the US FDA (Food & Drug Administration.  Encouraged, he later published Pharmacomastix, or the Office, Use, and Abuse of Apothecaries Explained (1741), the contents of which were used by the parliament to make certain legislative amendments.

However, as well as a radical, Lucas was a idealist and while the establishment was content to support him in matter of pills and potions, when he intruded into areas which disturbed the political equilibrium, they were less tolerant and, facing imprisonment, Lucas fled to the continent where he’d decided to study medicine, graduating as a doctor in 1752.  One of his first projects as a physician was a study of the composition of certain mineral waters, substances then held to possess some remarkable curative properties (something actually not without some basis).  To undertake his research he visited a number of sites including Spa, Aachen in what is now North Rhine-Westphalia and Bath in the English county of Somerset.  The material he assembled and published as An Essay on Waters. In three Parts: (i) of Simple Waters, (ii) of Cold Medicated Waters, (iii) of Natural Baths (1756) and it was in this work that the verb “deliquesce” first appeared.  Ever the “disturber” Dr Lucas’s tract upset the medical establishment in much the same way two decades earlier he’d stirred the enmity of the apothecaries, the cluster of physicians clustered around the Bath spa angered the interloper hadn’t consulted with them on a topic over which they asserted proprietorship.

In chemistry, the companion word of deliquescence is hygroscopy, both describing phenomena related to the ability of substances to absorb moisture from the surrounding environment, but they differ in extent and behavior.  Hygroscopy refers to the ability of a substance to absorb moisture from the air when exposed; hygroscopic substances can attract and hold water molecules onto their surface but tend not to dissolve.  Many salts behave thus and a well-known example of practical application is the silica gel, which, in small porous packages, is often used as a desiccant to absorb moisture in packaging. Deliquescence can be thought of an extreme form of hygroscopy (hydroscopy taken to its natural conclusion) in that a substance which deliquesces not only absorbs moisture from the air but also absorbs it to the point where it dissolves completely in the absorbed water, forming a solution.  In the natural environment, this happens most frequently when the relative humidity of the surrounding air is high and the classic deliquescent substances are salts like calcium chloride, magnesium chloride, zinc chloride, ferric chloride, carnallite, potassium carbonate, potassium phosphate, ferric ammonium citrate, ammonium nitrate, potassium hydroxide, & sodium hydroxide.  Presumably because deliquescence is the extreme form of hydroscopy it was the former which came to be used figuratively (dissolving into “nothing”) while the latter did not.

At the chemical level, hygroscopy (a class in which scientists include deliquescence as a sub-set) describes the phenomenon of attracting and holding water molecules via either absorption or adsorption (the adhesion of a liquid or gas on the surface of a solid material, forming a thin film on the surface.) from the surrounding environment.  Hygroscopy is integral to the biology of many plant and animal species' attainment of hydration, nutrition, reproduction and/or seed dispersal.  Linguistically, hygroscopy is quirky in that the construct is hygro- (moisture; humidity), from the Ancient Greek ὑγρός (hugrós) (wet, moist) + -scopy (observation, viewing), from the Ancient Greek σκοπέω (skopéō) (to see (and the source of the Modern English “scope”) yet unlike other forms suffixed by “-scopy”, it no longer conveys the sense of “viewing or imaging”.  Originally that was the case, a hygroscope in the late eighteenth century understood as a device used to measure humidity but in a wholly organic way this use faded (“dissolving deliquescently to nothing” as it were) while hygroscopic (tending to retain moisture) & hygroscopy (the ability to do so) endured.  The modern instrument used to measure humidity is hygrometer, the construct being hygro- + -meter (the suffix from the Ancient Greek μέτρον (métron) (measure) used to form the names of measuring devices.

Rabbit

Rabbit (pronounced rab-it)

(1) Any of several soft-furred, large-eared, rodentlike burrowing mammals of the family Leporidae, allied with the hares and pikas in the order Lagomorpha, having a divided upper lip and long hind legs, usually smaller than the hares and mainly distinguished from them by bearing blind and furless young in nests rather than fully developed young in the open.

(2) Any of various small hares.

(3) The fur of a rabbit or hare, often processed to imitate another fur.

(4) A runner in a distance race whose goal is chiefly to set a fast pace, either to exhaust a particular rival so that a teammate can win or to help another entrant break a record; pacesetter.

(5) In sport, a person poor at a sport; in cricket specifically, an unskilled batter (also as “batting bunny”, usually clipped to bunny).

(5) As Welsh rabbit, an alternative form of Welsh rarebit & Welsh ribbit (A snack made of cheese melted with a little ale and served on toast).  Welsh rabbit was the original form but was erroneously marked as a corruption in a dictionary published in 1785 although it’s not clear if the editor made the assumption or drew the conclusion from oral evidence.

(6) In nuclear engineering, a pneumatically-controlled tool used to insert small samples of material inside the core of a nuclear reactor.

(7) In computing theory, a large element at the beginning of a list of items to be bubble sorted, and thus tending to be quickly swapped into the correct position.

(8) In northern English regional slang, as “rabbit catcher”, a midwife or one who by force of circumstance assists in the delivery of a baby.

(9) As “rabbit ears”, the indoor dipole television antenna which typically sat atop the early analogue sets which received a terrestrial signal.

(10) Incessantly or nonsensically to talk.

(11) To hunt rabbits.

(12) In US slang, to flee.

1375-1425: From the late Middle English rabet & rabette, from the Anglo-Latin rabettus, from the Middle French rabouillet (baby rabbit), from the dialectal Old North French rabotte, probably a diminutive of Middle Dutch or West Flemish robbe (rabbit, seal), of uncertain origin but which may be an imitative verb (perhaps robben or rubben (to rub)) and used to allude to a characteristic of the animal.  The related forms include the French rabot (plane), the Middle Dutch robbe (rabbit; seal (from which Modern Dutch gained rob (seal (also “rabbit”), the Middle Low German robbe & rubbe (rabbit), the later Low German Rubbe (seal), the West Frisian robbe (seal), the Saterland Frisian Rubbe (seal) and the North Frisian rob (“seal”) eventually borrowed as the German Robbe (seal).  Early dictionary editors thus described the word as “a Germanic noun with a French suffix”.  Rabbit is a noun & verb, rabbitiness is a noun, rabbited is a verb, rabbitlike & rabbity are adjectives and rabbiting is a noun & verb; the noun plural is rabbits and (especially in the collective) rab·bit.

Until the late nineteenth century, the meaning was exclusively what would now be understood as “a young rabbit” but it came to be used of the whole species, replacing the original coney, owing to the latter's resemblance to and use as a euphemism for cunny (“vulva” and linked obviously with “cunt” although despite that the preferred slang with some zoological allusion came to include “beaver”, “camel toe” and (especially) “pussy”, rather than “bunny”).  The noun coney dates from the early thirteenth century and was abstracted from the Anglo-French conis and the Old French coniz, (plurals of conil (long-eared rabbit; (Lepus cunicula)) from the Latin cuniculus, the source also of the Spanish conejo, the Portuguese coelho and the Italian coniglio), the small, Spanish variant of the Italian hare (Latin lepus).  The word may ultimately be from the Iberian Celtic although classical writers said it was Hispanic.  In Middle English the two forms were cony & conny (the derivations including coning, cunin & conyng) while the Old French had conil alongside conin.  The evolution seems to be that the plural form conis (from conil, with the -l- elided) was taken into English and regularly single-ized as cony.  The Old French form was borrowed in the Dutch konijn and the German Kaninchen (a diminutive), and is preserved in the surname Cunningham (from a place-name in Ayrshire).  Rabbits not being native to northern Europe, there was no Germanic word for them.  In the fourteenth century “rabbit” came to describe the young of the species and over the centuries came to supplant coney, a process complete by the early nineteenth.  It was another of those exercises in sanitization because in English & Welsh slang, coney had been adopted as a punning synonym for cunny (cunt).  That was complicated by it appearing in the Book of Proverbs in the King James Version of the Bible (KJV, 1611) so the work-around was to change the pronunciation of the original short vowel (rhyming with honey, money) to rhyme with bony, stony.  In the Old Testament, the word translates the Hebrew shaphan (rock-badger).

When Volkswagen in 1974 introduced the Golf in the North American market, it was named the Rabbit, apparently because it would thought the name would suggest qualities such as “agility, speed & playfulness” which were positive attributes in what was then (by US standards) a very small car, much smaller than the more recent versions.  Because of the international success of the Golf, when the revised model was released in 1983, the North American cars switched to that name and it’s been marketed that way since except between 2003-2008 when the Rabbit badge was revived.  The revival was in retrospect a curious choice given the obvious advantages offered by using the one name globally but at the time VW America had a rationalization: “We think we have some opportunities to do something creative with the Rabbit nameplate and recognizes the Golf nameplate has never really caught on with North American consumers as it was overshadowed by the Jetta sedan and wagon.  Volkswagen customers want a relationship with their cars and names like The Thing, Beetle, Fox and Rabbit support this."  Whatever the opportunities may have been, the linguistic experiment wasn’t continued and since 2009, it’s been Golfs all the way.

There was some linguistic irony in VW’s choice because as the US satirist & critic HL Mencken (1880–1956) pointed out in The American Language; An Inquiry into the Development of English in the United States (1919): “Zoologically speaking, there are no native rabbits in the United States; they are all hares. But the early colonists, for some unknown reason, dropped the word hare out of their vocabulary, and it is rarely heard in American speech to this day. When it appears it is almost always applied to the so-called Belgian hare, which, curiously enough, is not a hare at all, but a true rabbit.”

The White Rabbit was a character in Lewis Carroll’s (1832–1898) Alice’s Adventures in Wonderland (1865) and one which appears often, always in a waistcoat with pocket watch and in a hurry, fearful always of the impending fury the duchess will visit upon him should he be a moment late.  It’s the white rabbit which Alice follows down the rabbit hole, leading to the bizarre adventures recounted.  One of popular culture’s best-known rabbits gave rise to the phrase “bunny boiler”, a reference to the scene in the film Fatal Attraction (1987) in which a scorned woman revenged herself upon her adulterous ex-lover by tossing his daughter’s pet rabbit into a pot of boiling water; he arrives home to discover a boiled bunny.  The Warner Brother cartoon character Bugs Bunny first appeared on the screen in 1938 and is often described by his shotgun wielding antagonist, the lisping Elmer Fudd, as "that wascally wabbit".

In idiomatic use there’s “pull a rabbit out of the hat” (to find or obtain a sudden solution to a problem), “rabbit-hearted” (someone timid or inclined to be flighty), “rabbit food” (a disapproving view of vegetables held by some meat-eaters), “the rabbit test” (an early pregnancy test involving the injection of the tested woman's urine into a female rabbit, then examining the rabbit's ovaries a few days later for changes in response to a hormone (“the rabbit died” the phrase indicating a positive test or an admission of one’s pregnancy)), “breed like rabbits” (slang for an individual, family, or sub-group of a population with a high birth-rate), “down the rabbit hole” (a time-consuming tangent or detour, often one from which it’s psychologically difficult to extricate oneself), “lucky rabbit’s foot”, (the carrying of a luckless bunny’s preserved rabbit’s foot as a lucky charm), “like a rabbit warren” (a confusingly labyrinthine environment (used literally & figuratively)), “rabbit in the headlights” (an allusion to the way rabbits (like some other wildlife) sometimes “freeze” when caught in the light of an oncoming vehicle’s headlamps) and the inevitable “rabbit fucker” (a general term of disparagement (although it could be applied literally in the right circumstances)).

The “earless” rabbit with “eared” companions.

In May 2011, some weeks after the meltdown at Fukushima Dai-ichi nuclear plant which suffered severe damage in the aftermath of the earthquake and tsunami, a video of an “earless rabbit” began to circulate, purportedly captured in an area just beyond the crippled plant’s exclusion area.  The immediate speculation was of course the creature’s unusual state was a result of a radiation-induced genetic mutation.  Geneticists however had a less troubling explanation.  Although there’s no doubt the radiation emitting from Fukushima Dai-ichi (some 225 kilometres (140 miles) north-east of Tokyo) represents a major risk to health and the long-term environmental effects remain unclear, the scientists say not only is it unlikely to be linked with the earless rabbit, such creatures are far from unusual.  According to a  statement issued from Colorado State University's Department of Environmental and Radiological Health Sciences: “…radiation can cause mutations that can be occasionally expressed as obvious birth defects, such as shown in the video.  However, to say this is the result of contamination from the Fukushima accident is a stretch, because natural radiation, as well as many other chemical substances in the environment and other factors, can also be mutagenic.  In most cases, the cause of congenital birth defects in humans and other animals cannot be determined and as far as science has shown, there have never been mutations produced by ionizing radiations that do not occur spontaneously as well.”

The rabbit does though have a place in nuclear engineering.  In the industry, the term “rabbit” is used to describe a range of pneumatically controlled tools which are used remotely to insert or retrieve items from a nuclear reactor or other radioactive environments.  The name is thought to come from the devices being tubular (on the model of the rabbit borrow) which allows samples rapidly to be injected into the periphery of a reactor core, the injectables moving “with the speed of startled rabbits” although there may also be the implication of rabbits as expendable creatures, the tool essential for maintenance, inspection, and repair tasks in nuclear facilities, where direct human intervention is either dangerous or impossible because of high radiation levels.

Winston Churchill inspecting the progress of project White Rabbit No, 6, Clumber Park, Nottinghamshire, England, November 1941.

The World War II (1939-1945) era White Rabbit No. 6 was an engineering project by the British Admiralty although as a security measure the official code-name was changed to Cultivator No. 6 to make it sound less mysterious and more like a piece of agricultural equipment.  It was a military trench-digging machine and an example of the adage that “generals are always preparing to fight the last war” and although designed exclusively for army use on (and at least partially under) land, it came under the auspices of the Royal Navy because it was a brainchild (one of many) of Winston Churchill (1875-1965; UK prime-minister 1940-1945 & 1951-1955) who, between the outbreak of war in 1939 and his assumption of the premiership some months later, served as First Lord of the Admiralty (the service’s civilian head).  Trenches and artillery had been the two dominant features of World War I (1914-1918) and Churchill had spent some months (1915-1916) in one of the former while under fire from the latter while commanding a battalion; before the implications of mechanization and the German’s Blitzkrieg (lightning war) tactics were apparent, he assumed the new war in France would unfold something like the old, thus the interest in something which would “revolutionize trench warfare”.  Trench warfare however wasn’t repeated so White Rabbit No.6 was soon realized to be already obsolete and the project was abandoned and although the most fully developed of the prototypes did perform according to the design parameters, whether it would have been effective remains doubtful; remarkably, work on these things wasn’t wholly abandoned until 1942.  The “White Rabbit” project codes came from Churchill’s sense of humor, his ideas coming, as he said: “like rabbits I pull from my hat” and he supported many, some of which were of great military value while others, like the “floating runways” (artificial icebergs made with a mixture of shards of timber & frozen water), were quixotic.

Surrealistic Pillow album cover, 1967.

White Rabbit was a song by Grace Slick (b 1939) and released on the album Surrealistic Pillow by Jefferson Airplane.  The lyrics were inspired by Lewis Carroll's Alice's Adventures in Wonderland and the sequel Through the Looking-Glass (1871).  It was the psychedelic era and drug references were common in popular music and in the case of White Rabbit it may have been appropriate if the speculation the books been written while the author was under the influence of Laudanum (a then widely-available opiate-infused drug) is true (there's no evidence beyond the circumstantial).  Given the imagery in the text, it’s not difficult to believe he may have been on something and among authors and poets it was a popular way to stimulate the imagination, inspiring at least some of one of the most beloved fragments of English verse, Samuel Taylor Coleridge’s (1772-1834) Kubla Khan (1797) which ends abruptly at 54 lines.  According to Coleridge, he was unable to recall the rest of the 300-odd which had come to him in an opium-laced dream (the original publication was sub-titled “A Vision in a Dream”) because he was interrupted by “a person on business from Porlock” (a nearby Somerset village).  Grace Slick would have sympathized with an artist being intruded on by commerce.

White Rabbit lyrics:

One pill makes you larger

And one pill makes you small

And the ones that mother gives you

Don't do anything at all

Go ask Alice

When she's ten feet tall

 

And if you go chasing rabbits

And you know you're going to fall

Tell 'em a hookah-smoking caterpillar

Has given you the call

Call Alice

When she was just small

 

When the men on the chessboard

Get up and tell you where to go

And you've just had some kind of mushroom

And your mind is moving low

Go ask Alice

I think she'll know

 

When logic and proportion

Have fallen sloppy dead

And the White Knight is talking backwards

And the Red Queen's off with her head

Remember what the dormouse said

Feed your head

1375-1425: From the late (northern) Middle English swirlen (to eddy, swirl) which was probably from the Old Norse svirla (to swirl), a frequentative form of Old Norse sverra (to swing, twirl).  It was cognate with the Scots swirl & sworl (to eddy, swirl), the Norwegian Nynorsk svirla (to whirl around; swirl), the Swedish sorla (to murmur, buzz) and the Dutch zwirrelen (to swirl).  Related forms included the dialectal German schwirrlen (to totter), the West Frisian swiere (to reel, whirl), the Dutch zwieren (to reel, swing around), the German Low German swirren (to whizz, whirl or buzz around), the German schwirren (to whirr, whizz, buzz), the Swedish svirra (to whirr about, buzz, hum), the Danish svirre (to whizz, whirr) and the English swarm.  The construct may be understood as the Germanic root swir- + -l- (the frequentative suffix).  Swirl is a noun & verb, swirled is a verb & adjective, swirling is a noun, verb & adjective, swirly is a noun & adjective, swirler is a noun and swirlingly is an adverb; the noun plural is swirls.

In English, the late (northern) Middle English noun swirlen (to eddy, swirl) seems originally to have come from a Scottish word, the origin of which is undocumented but etymologists seem convinced of the Scandinavian links.  The sense of a “whirling movement” emerged in the early nineteenth century although the meaning “a twist or convolution (in hair, the grain of wood etc)” was in use by 1786.  The verb as a transitive in the sense of “give a swirling or eddying motion to” was in use in the early sixteenth century but it may by then long have been in oral use, one text from the fourteenth containing an example and the source of that may have been either Germanic (such as the Dutch zwirrelen (to swirl) or the Norwegian Nynorsk svirla (to whirl around; swirl) or it may have evolved from the English noun.  The intransitive sense (have a whirling motion, form or whirl in eddies) dates from 1755.  The adjective swirly existed by 1785 in the sense of “twisted or knotty” but by the middle of the next century it had come also to describe anything “whirling or eddying”, applied especially to anything aquatic.  By 1912, it was used also to mean “full of contortions or twists” although “swirling” in this sense had by then been in (gradually increasing) use for a century.

Of curls & swirls: Lindsay Lohan with curls (left) and swirls (right).

In hairdressing, although customers sometimes use the words “curl” and “swirl” interchangeably, to professionals the use should be distinct.  A swirl is a movement or pattern in which hair is styled or arranged, typically with a rounded or circular pattern and swirls can be natural (the pattern at the crown of the head where the hair grows in a circular direction) or stylized (the look deliberately created and most obvious in “up-dos) or the formal styles associated with weddings and such).  The end result is a wide vista and the swirl is more a concept than something which exists within defined parameters.  A curl is (1) a type of hair texture or (2) the act of creating a curl with techniques using tools and/or product.  Some people (and there’s a strong ethnic (ie genetic) association) naturally have curly hair due to the shape of their follicles and within the rubric of what used to be called the ulotrichous, hairdressers classify curls as tyree types: (1) tight (small, corkscrew-like structures), (2) medium (tighter curls but with a softer appearance) and (3) long spirals with a large diameter).  Some commercial product also lists “ringlets” as a type but as tight, well-defined spirals, they’re really a descriptive variation of the tight or medium.  So, the essential difference is that a swirl is a pattern or movement of the hair, while a curl describes texture or shape and while a swirl is a matter or arrangement, a curl demands changing the hair’s natural texture or shape.  Swirls are very much set-piece styles associated with formal events while curls are a popular way to add volume, texture, and movement to the hair.

In internal combustion engines (ICE), the “swirl chamber is a now generic term used to describe a widely-used type of combustion chamber when upon introduction, the fuel-air mixture “swirls around” prior to detonation.  The design is not new, Buick’s straight-8 “Fireball” cylinder head using a simple implementation as long ago as the 1920s and it would serve the corporation into the 1950s.  The critical aspect of the engineering was the interaction between a receded exhaust valve and a rising in the top of the piston which “pushed” most of the fuel-air mixture into what was a comparatively small chamber, producing what was then called a “high-swirl” effect, the “Fireball” moniker gained by virtue of the actual combustion “ball of fire” being smaller in volume than was typical at the time.  The benefit of the approach was two-fold: a reduction in fuel consumption because less was required per power-stroke and (2) a more consistent detonation of the poor quality fuel then in use.  As fuel improved in quality and compression ratios rose (two of the dominant trends of the post-war years), the attraction of swirl chambers diminished but the other great trend was the the effective reduction in the cost of gasoline (petrol) and as cars became larger & heavier and roads more suited to higher speeds, the quest was for power.

Power in those years usually was gained by increased displacement & combustion chamber designs optimized for flow; significantly too, many popular designs of combustion chamber (most notably those in the so-called “wedge” heads) were cheaper to produce and in those years, few gave much thought to air-pollution.  The cars of the 1950s & 1960s had really toxic exhaust emissions.  By the mid 1960s however, the problem of air pollution in US cities was so obvious and the health effects were beginning to be publicized, as was the contribution to all of this by motor vehicles.  Regulations began to appear, California in 1961 (because of the high vehicle population and certain geographical & climatic phenomena, Los Angeles & San Francisco were badly affected by air pollution) passing the first statute and the manufacturers quickly agreed to adopt this standard nationally, fearing other states might begin to impose more onerous laws.  Those however arrived by mid-decade and although there was specific no road-map, few had any doubts the rules would become stricter as the years passed.  The industry’s only consolation was that these laws would be federal legislation so they would need to offer only one specification for the whole country (although the time would come when California would decide things should be tougher and by the 1970s there were “Californian cars” and “49 state cars”).  K Street wasn’t the force then it later became and the manufacturers conformed with (relatively) little protest.

Fuel was still cheap and plentiful but interest in swirl chambers was revived by the promise of cleaner burning engines.  Because it wasn’t new technology, the research attracted little attention outside of the engineering community but in 1970, German-born Swiss engineer Michael May (b 1934) demonstrated a Ford (Cologne) Capri with his take on the swirl chamber in a special cylinder head.  In a nod to the Buick original, May nick-named his head design the “Fireball” (professional courtesy a thing among engineers).  What Herr May had done was add a small groove (essentially a channel surrounding the intake valve) to the chamber, meaning during the last faction of a second of piston movement, the already swirling fuel-air mixture got a final nudge in the right direction: instead of there being a randomness to the turbulence of the mix, the shape was controlled and was thus able to be lower in volume (a smaller fireball) and precisely controlled at the point at which the spark triggered detonation; May called this a “higher swirl”.  Not only did this reduce exhaust emissions but it also cut fuel consumption for a given state of tune so designers could choose their desired path: more power for the same fuel consumption or the same power for less and within a short time, just about the whole world was taking great interest in fuel consumption.

A noted use of May’s design was its adoption in 1981 on Jaguar’s infamously thirsty V12 (1971-1997), an innovation celebrated by the addition of the HE (High Efficiency) label for the revised power-plant.  The notion of “high efficiency” was comparative rather than absolute and the V12 remained by most standards a thirsty beast but the improvement could be in the order of 40% (depending on conditions) and it was little worse than the similar displacement Mercedes-Benz V8s of the era which could match the Jaguar for power but not the turbine-like smoothness.  Threatened with axing due to its profligate ways, the swirl chambers saved the V12 and it survived another sixteen years which included two severe recessions.  Debuting even before the Watergate scandal, it lasted until the Monica Lewinsky affair.  In the decades since, computer simulations and high-speed photography have further enhanced the behavior of swirl & turbulence, the small fireballs now contained in the center of the chamber, prevent heat from radiating to the surrounding surfaces, ensuring the energy (heat) is expended on pushing the piston down to being the next cycle, not wasting it by heating metal.  The system is popular also in diesel engines.

Indigo

Indigo (pronounced in-di-goh)

(1) A blue dye obtained from various plants, especially of the genus Indigofera, or manufactured synthetically.

(2) A descriptor of color indigo, widely defined commercially and ranging from a deep violet blue to a dark, greyish blue (sometimes as "indigo blue").

(3) In technical use, as indigo blue (also casually referred to as indigotin or indigo), a dark-blue, water-insoluble, crystalline powder (C₁₆H₁₀N₂O₂), having a bronze-like luster, the essential coloring principle of which is contained along with other substances in the dye indigo and which can be produced synthetically.

(4) Any of numerous hairy plants belonging to the genus Indigofera, of the legume family, having pinnate leaves and clusters of usually red or purple flowers (the best-known of the plants including Amorpha (false indigo), Baptisia (wild indigo), and Psorothamnus and Dalea (indigo bush)).

(5) In zoology, as the Eastern indigo snake, the common name for the Drymarchon couperi.

(6) In zoology, as the indigobird (or indigo bird), any of various African passerine birds of the family Viduidae.

(7) A (rarely used) female given name.

1550s: The spelling change from indico to indigo happened in the 1550s, used originally in the sense of the “blue powder obtained from certain plants and used as a dye”.  Indigo was from the Spanish indico and the Portuguese endego (the Dutch indigo exclusively was from Portuguese), all from the Latin indicum (indigo), from the Ancient Greek ἰνδικόν (indikón) (Indian blue dye (literally “Indian substance”)), a neuter of indikos (Indian), from the Indic Ἰνδία (Indía).  Indic is a subgroup of the Indo-Iranian branch of Indo-European languages that includes Sanskrit, Hindi, Urdu, Bengali, and many other languages of India, Pakistan, and Sri Lanka; Indo-Aryan.  It replaced the late thirteenth century Middle English ynde, from the thirteenth century Old French inde (indigo; blue, violet), again from the Latin indicum; the earlier name in Mediterranean languages was annil or anil.  In the magical-realist novel Sassafrass, Cypress & Indigo (1982) by African American feminist Ntozake Shange (1948–2018), the name of one protagonist is Indigo and it continues to be used as a given name for females.  Indigo is a noun & adjective and indigotic is an adjective; the noun plural is indigos or indigoes.

Sir Issac Newton, light and the "two prism experiment" 

As used to refer to “the color of indigo”, use dates from the 1620s and in 1704 Sir Isaac Newton (1642–1727) adopted indigo as the name for the darkest of the two blues on his spectrum of the visible colors of light.  Newton identified seven colors in the spectrum of light (red, orange, yellow, green, blue, indigo and violet) and although he was a great figure of science and the Enlightenment, he was also an alchemist and theologian who published notable works of Biblical scholarship, something which may account for the choice of seven, that number being of some significance in scripture.  By objective analysis, there are probably six colors in the spectrum, but Newton’s world view which attributed something mystical to the number demanded there be seven.  He decided in advance light was made of seven colors but his experimental method to vindicate this theory of differential refraction was sound.  The orthodox view of the time suggested a prism acted on any incident light to add colour; Newton wished to prove what was really happening was a process of separation refraction.  For this, he used two prisms.  The first produced the full spectrum of colors and from this Newton isolated narrow beams of light of a single colour, directing them at the second prism, finding that for all colors, there was no further change as the beam passed through the second prism: “When any one sort of Rays hath been well parted from those of other kinds, it hath afterwards obstinately retained its colour, not with standing my utmost endeavours to change it.”

Lindsay Lohan shopping at Indigo Seas, North Robertson Boulevard, Los Angeles, February 2009.  Most fashion houses would regard her dress’s blue as “too blue” to be within the indigo range but to illustrate how far (in commercial use) indigo can travel from blue, some would call this "Spanish indigo" (Hex: #003C92; RGB: 0, 60, 148).

Although some use extends even to grey, generally, indigo is a range of bluish-purples between blue and violet in the color wheel and such is the reverence for Newton it’s considered still one of the seven spectral colors (indigo’s hex code is #4B0082),  In this, although it may visually be dubious, indigo has fared better than the unfortunate Pluto, the International Astronomical Union (IAU) voting in 2006 to re-classify Pluto as a dwarf planet on the basis the icy orb failed to meet a set of criteria which the IAU claimed had been accepted for decades.  The IAU are a bunch of humorless cosmic clerks, something like the Vogons ("...not actually evil, but bad-tempered, bureaucratic, officious and callous.") in Douglas Adams’ (1952–2001) Hitchhiker's Guide to the Galaxy (1978) and, not affected by romantic tales, have refused to restore Pluto to planethood, leaving it desolate, lonely and cold; it's the solar system’s emo.  Indigo place on the spectrum seems however secure and according to Canva (the internet’s authority on colors), it’s the color of devotion, wisdom, justice, and higher knowledge; tied to intuition and what is not seen; it is also considered spiritual.  More prosaically, Canva list indigo as hexadecimal #4b0082, with RGB values of Red: 29.4, Green: 0, Blue: 51 and CMYK values of Cyan: 0.42, Magenta: 1, Yellow: 0, Black (K):0.49.  The decimal value is 4915330.  It has a hue angle of 274.6 degrees, a saturation of 100% and a lightness of 25.5%. #4b0082 color hex could be obtained by blending #9600ff with #000005. Closest websafe color is: #330099.

Atomism

Atomism (pronounced at-uh-miz-uhm)

(1) In philosophy, an ancient theory, developed by Democritus and expounded by Lucretius, that the ultimate constituents of all matter in the universe are atoms which are minute, discrete, finite, and indivisible elements; also called atomic theory.

(2) In psychology, a method or theory that reduces all psychological phenomena to simple elements; that experiences and mental states are composed of elementary units.

(3) Within the sciences, any of a number of theories that hold that some objects or phenomena can be explained as constructed out of a small number of distinct types of simple indivisible entities; any theory that holds that an understanding of the parts is logically prior to an understanding of the whole.  These theories can be grouped under the rubric of reductionism

1670–1680: The construct was atom + -ism.  Atom was from the Middle English attome from the Middle French athome, from the Latin atomus (smallest particle), from the Ancient Greek ἄτομον & ἄτομος (átomos & átomon) (indivisible; uncuttable), the construct being ἀ- (a-) (not) +‎ τέμνω (témnō) (I cut).  The –ism suffix was from the Ancient Greek ισμός (ismós) & -isma noun suffixes, often directly, sometimes through the Latin –ismus & isma (from where English picked up ize) and sometimes through the French –isme or the German –ismus, all ultimately from the Ancient Greek (where it tended more specifically to express a finished act or thing done).  It appeared in loanwords from Greek, where it was used to form abstract nouns of action, state, condition or doctrine from verbs and on this model, was used as a productive suffix in the formation of nouns denoting action or practice, state or condition, principles, doctrines, a usage or characteristic, devotion or adherence (criticism; barbarism; Darwinism; despotism; plagiarism; realism; witticism etc).

Many English nouns to which -ism is attached are loans from Ancient Greek (mostly via Latin and French).  In Late Latin, the -ismus suffix became the ordinary ending for names of religions and ecclesiastical or philosophical systems, a trend continued in Medieval Latin and from the sixteenth century, such formations became common in English although, until the eighteenth century, the use was usually restricted to either root words from Ancient Greek & Latin or proper names.   By the nineteenth century, the creation of “isms” began to expand and by the twentieth, coinages took no account of previous rules and conventions.  Atomism & atomist are nouns, atomistic & atomistical are adjectives and atomistically is an adverb; the noun plural is atoms.

Atoms and voids

Atomism was a philosophical theory which suggested the universe consisted of indivisible, minute particles known as atoms and the idea was ancient, the first known writings on the matter those of the Ancient Greek philosopher Leucippus who was born during the fifth century BC but it was his better-known pupil Democritus (circa 460-370 BC) who developed and systematized the ideas.  What emerged was the theory that the two diametrically opposed constituents of the universe are indivisible entities: the void and the atom.  Democritus regarded a void as being literally nothing whereas atoms were matter and intrinsically unchangeable; an atom moving about in the void and sometimes combining into clusters although, being separated by the void, they cannot fuse, but instead bounce off one another when they collide.  It was the origin of the understanding that in the material world, objects are transitory because they change as their constituent atoms shift or become detached; matter cannot be created or destroyed, it can only be transformed into something else.  To the philosopher, it meant everything we experience in the universe is doomed; it’s a question just of when it ends and how.  That’s sometimes expressed as “nothing lasts forever” and in a practical sense that’s correct but what was left unanswered (though not unexplored) was (1) whether the atoms survived no matter what and (2) whether the voids remained or became transformed into a singularity with an undetermined future.

Helpfully for some, the atomists’ postulation of the indivisible atom also provided a solution to one of the paradoxes of Zeno of Elea (circa 495–430 BC): that if magnitudes can be divided to infinity, it becomes impossible for movement to happen because the object would have to traverse an infinite number of spaces in a finite time.  If an atom is the point at which division is impossible, the dilemma, which admittedly occurs only in Philosophy 101 classes, dissolves.  Other problems however persisted because there was nothing to disprove the proposition an atom could infinitely be divided into progressively smaller parts and obviously such a process could be described mathematically, numbers extending infinitely in each direction from what would come to be called zero.

Atomism: Atomic Kitten, EMI promotional poster, 1999.

The notion all matter is composed of tiny, indivisible (and indestructible) particles called atoms (from a Greek form meaning “indivisible” or “uncuttable” endured well in both Western and Eastern traditions although there were those who resisted and clung to the model of continuous matter, something which would have seemed compelling obvious based on observation.  What the thinkers from Antiquity left however was something speculative and, given the technology of the time, wholly unsupported by empirical evidence but with the advances which followed the Enlightenment, there was renewed interest in what was at the time known variously as “modern” or “revival” atomism and the first structured theories emerged in the early 1800s.  Indeed, the diagrams and explanations which became widely available early in the twentieth century really made the atomic structure understandable (at least conceptually) even to those with no background which was fine until the shock of quantum mechanics, papers and discussions about which began to circulate in the 1920s.  Quite a jump in the understanding of atoms and sub-atomic particles, quantum theory did not describe atoms as solid, billiard ball-like objects but rather as probabilistic entities with wave-like properties, the most challenging implication of that being that such a thing could simultaneously be in two places (points in space) at the same time (points in time).  For those brought up on the neat little diagrams of the atom, it was quite a challenge to visualize those two points in space being possibly on opposite sides of the universe.
