1635–1645: From the early Modern English react (to exert, as a thing acted upon, an opposite action upon the agent).  The construct was re- + act, thought to have been modeled on the Medieval Latin reagere, the construct being re- + agere (to drive, to do).  Act was from the Middle English acte, from the Old French acte, from the Latin ācta (register of events), the plural of āctum (decree, law), from agere (to do, to act), ultimately from the primitive Indo-European héǵeti and related to the German Akte (file); it partially displaced deed, from the Old English dǣd (act, deed) which endured and (especially in law), flourished in parallel.  The re- prefix was from the Middle English re-, from the circa 1200 Old French re-, from the Latin re- & red- (back; anew; again; against), from the primitive Indo-European wre & wret- (again), a metathetic alteration of wert- (to turn).  It displaced the native English ed- & eft-.  A hyphen is not normally included in words formed using this prefix, except when the absence of a hyphen would (1) make the meaning unclear, (2) when the word with which the prefix is combined begins with a capital letter, (3) when the word with which the is combined with begins with another “re”, (4) when the word with which the prefix is combined with begins with “e”, (5) when the word formed is identical in form to another word in which re- does not have any of the senses listed above.  As late as the early twentieth century, the dieresis was sometimes used instead of a hyphen (eg reemerge) but this is now rare except when demanded for historic authenticity or if there’s an attempt deliberately to affect the archaic.  Re- may (and has) been applied to almost any verb and previously irregular constructions appear regularly in informal use; the exception is all forms of “be” and the modal verbs (can, should etc).  Although it seems certain the origin of the Latin re- is the primitive Indo-European wre & wret- (which has a parallel in Umbrian re-), beyond that it’s uncertain and while it seems always to have conveyed the general sense of "back" or "backwards", there were instances where the precise was unclear and the prolific productivity in Classical Latin tended make things obscure.  The Latin prefix rĕ- was from the Proto-Italic wre (again) and had a parallel in the Umbrian re- but the etymology was always murky.   In use, there was usually at least the hint of the sense "back" or "backwards" but so widely was in used in Classical Latin and beyond that the exact meaning is sometimes not clear.  Etymologists suggest the origin lies either in (1) a metathesis (the transposition of sounds or letters in a word) of the primitive Indo-European wert- (to turn) or (2) the primitive Indo-European ure- (back), which was related to the Proto-Slavic rakъ (in the sense of “looking backwards”).

The hyphenated form re-act (to act or again perform) began to develop during the 1650s (although the hyphen wasn’t de rigueur for decades) and there’s evidence to suggest there was often either an exaggerated pronunciation of the “re-“ or a slight pause between syllables to distinguish it from react.  Forms like overreact & overreaction (1928), interreact, interreaction (1820s), reactivate (1902 & reactivation etc were coined as required.  React is a noun & verb, reactive is an adjective, reactor, reaction & reactant are nouns, reactionary is a noun & adjective, reactivate, reacted & reacting are verbs,; the noun plural is reacts.

The noun reactant (a reacting thing) came from chemistry and dates from 1901; as an adjective it was noted in the literature by 1911 although it may have been in oral use for some time and the noun reactance had been in the vocabulary of science since at least 1893.  The noun reactor (one that reacts) was a standard entry in the books of Latin instruction by 1825 but came into common use in the electrical industry after 1915 to describe “coil or other piece of equipment which provides reactance in a circuit”.  The word is now most commonly associated with nuclear energy, the reactor technically the component in a power-plant, submarine etc, where the nuclear reactions are contained but in the popular imagination often used of the power-generating installations to describe the entire facility.  The adjective reactive dates from 1712 in the sense of “a repercussive, echoing” although that use is long obsolete.  It was re-purposed in the early nineteenth century to mean “caused by a reaction” and by 1888 as “susceptible to (chemical) reaction” and in chemistry the related forms were reactively, reactiveness & reactivity, the words required as new chemicals and elements were subjected to experiments determining the behavior when exposed to others.

The noun reaction (action in resistance or response to another action or power), although later much used in chemistry, dates from the language of physics & dynamics in the 1640s and came frequently to be seen in discussions of politics and international relations.  It was modeled on the French réaction, from the older Italian reattione, from the Medieval Latin reactionem (nominative reactio), a noun of action formed in Late Latin from the past-participle stem of Latin reagere.  In chemistry it was of course invaluable when describing “a mutual or reciprocal action of chemical agents upon each other” and it was the standard noun thus used by 1836.  The more general sense of "action or feeling in response" (to something said, an event etc) was from the early twentieth century.  The phrase reaction time (time elapsing between the action of an external stimulus and the giving of a signal in reply) was a creation of experimental science and first documented in 1874; it was later widely used (both as a precise measure and something indicative) in fields as varied as zoology, sport and electoral behavior.  Sometimes, the experiments to measure reaction times were conducted in a reaction chamber.

The adjective reactionary (of or pertaining to political reaction, tending to revert from a more to a less advanced policy) dates from 1831 and was on the model of the French réactionnaire.  It was part of Karl Marx's (1818-1883) standard set of descriptive terms by 1858, used to convey the idea of “tending toward reversing existing tendencies” and was the opposite of the ”revolutionary”.  The classic reactionary era is now that created by the Congress of Vienna (1514-1815) when the old monarchies contrived to ensure they wouldn’t again be threatened by something like the French Revolution (1789).  So dominant did the use in politics become that the use in science (of or pertaining to a chemical or other reaction) became rare.  In political science, the term reactionary is applied with rather more precision than in general use where, like fascist, it’s tended to become a general term of disapprobation for those who espouse an opposing view.  When applied with some academic rigor, it refers properly to the view that a previous political state of society is desirable and that action should be taken to return to those arrangements.  A reactionary is thus different from a conservative who wishes to keep things as they are but perhaps (at least sometimes) synonymous with ultra-conservative or arch-conservative, the classic example in politics being Prince Klemens von Metternich (1773–1859; foreign minister or chancellor of the Austrian Empire 1809-1848) who constructed an intricate model of Europe which was design to avoid another unpleasantness (for the ruling class) like the French revolution (1789) and its aftermath.  It’s usually thought of as somewhere on the spectrum of conservatism although there are logical (as well as linguistic) problems with that and either in theory or historic practice, reactionary ideologies, although radical, haven’t always been the most extreme of the breed.  Even that sort of terminology wasn’t reliably indicative of anything except what the author intended, Sir Garfield Barwick (1903–1997; Chief Justice of Australia 1964-1981) giving his autobiography the title A Radical Tory (1995), a few reviewers enjoying the opportunity to point out he was neither.

Thou shalt not: Pope Pius IX and friends.

In the UK there were of course already the Tories but it was the French Revolution from which English gained the descriptors "conservative", "right-wing" and "reactionary".  Conservative was from the French conservateur and was applied to those deputies of the French assembly which supported the monarchy (ie they wish to conserve that which was).  The term right-wing came to be used because when the Estates General was summoned in 1789, liberal deputies (the Third Estate) sat usually to left of the presiding officer's chair while the (variously usually either conservative or reactionary) members of the aristocracy (the Second Estate) sat to the right (the clerics were the First Estate and it’s from here is derived the later idea of the press as the Fourth Estate).  Reactionary was from the late eighteenth century French réactionnaire (from réaction (reaction)) and was used to denote "a ideology directed to return the structure of the state and the operation of society to a previous condition of affairs".  The Oxford English Dictionary (OED) dates the first use of the word in English to 1799 and political scientists have managed to coin variations like reactionist and even the (thankfully rare) reactionaryism.  In theology, the classic reactionary was Pope Pius IX (Giovanni Maria Mastai Ferretti, 1792–1878; pope 1846-1878) who in 1864 published Syllabus Errorum (Syllabus of Errors), a still controversial document which listed all the ideas of modernity which His Holiness thought most appalling and which should be abandoned because the old ways are the best.  Had he lived, his Holiness would have noted with approval the entry in that manual curmudgeons, Henry Fowler's (1858–1933) A Dictionary of Modern English Usage (1926): "The word derives its pejorative sense from the conviction, once firmly held but now badly shaken, that all progress is necessarily good."

Mansfield

Mansfield (pronounced manz-feeld)

The slang term for the protective metal structures attached to the underside of trucks and trailers, designed to protect occupants of vehicles in “under-run” crashes (the victim’s vehicle impacting, often at mid-windscreen height with the solid frame of the truck’s tray).  A Mansfield bar, technically is called the RUPS (Rear Underrun Protection System).

1967: The devices are known as “Mansfield” bars because interest in the system was heightened after the death of the actress Jayne Mansfield (1933-1967), killed in an under-run accident on 28 June 1967.  The origin of the surname Mansfield is habitational with origins in Mansfield, Nottinghamshire. The early formations, recorded in the thirteenth century Domesday Book, show the first element uniformly as the Celtic Mam- (mother or breast (Manchester had a similar linkage)) with the later addition of the Old English feld (pasture, open country, field) as the second element.  The locational sense is thus suggestive of an association of the field by a hill called “Man”.  The etymology, one suspects, would have pleased Jayne Mansfield.

The "Mansfield crash" aftermath, 1966 Buick Electra 225, 28 June, 1967 (left) and the much re-printed photograph (right) of Sofia Loren (b 1934, left) and Jayne Mansfield (right), Romanoff's restaurant, Beverly Hills, Los Angeles, April 1957.  Ms Loren's sideways glance, one of the most famous in Hollywood's long history of such looks has been variously interpreted as "sceptical", "disapproving" and "envious", the latter a view probably restricted to men.  Ms Loren herself explained her look as one of genuine concern the pink satin gown might not prove equal to the occasion.  On the night, there were several photographers covering the event and images taken from other angles illustrate why that concern was reasonable.  There has never been any doubt Ms Mansfield's "wardrobe malfunction" was "engineered and rehearsed".   

On 28 June 1967, Jayne Mansfield was a front-seat passenger in a 1966 Buick Electra 225 four-door hardtop, en route to New Orleans where she was next day to be the subject of an interview.  While cruising along the highway at around two in the morning, the driver failed to perceive the semi-truck in front had slowed to a crawl because an anti-mosquito truck ahead was conducting fogging and blocking the lane.  The mist from the spray masked the truck's trailer and, the driver unable to react in time, the car hit at high speed, sliding under the semi-trailer, killing instantly the three front-seat occupants.  Although the myth has long circulated she was decapitated, an idea lent some credence by the visual ambiguity of photographs published at the time, while it was a severe head trauma, an autopsy determined the immediate cause of death was a "crushed skull with avulsion of cranium and brain".  The phenomenon of the “under-run” accident happens with some frequency because of a co-incidence of dimensions in the machines using the roads.  Pre-dating motorised transport, loading docks were built at a height of around four feet (48 inches; 1.2 m) because that was the most convenient height for men of average height engaged in loading and unloading goods.  Horse-drawn carts and later trucks were built to conform to this standard so trays would always closely align with dock.  Probably very shortly after cars and trucks began sharing roads, they started crashing into each other and, despite impact speeds and traffic volumes being relatively low, the under-run accident was noted in statistics as a particular type as early as 1927.

In the post-war years, speeds and traffic volumes rose and, coincidentally, the hood-lines (bonnet) on cars became lower, the windscreen now often somewhere around four feet high so the under-run vulnerability was exacerbated, cars now almost designed to slide under a truck to the point of the windscreen, thus turning the tray into a kind of horizontal guillotine, slicing into the passenger compartment at head-height.  That’s exactly how Jayne Mansfield died and while the Buick was an imposing 223.4 inches (5,674 mm) in length, it was much lower than the sedans of earlier generations.  As a footnote, when introduced in 1959, the Electra 225 (1959-1980) gained its name from being 225.4 inches (5,725 mm) long and while during the 1960s it would be just a little shorter, by 1970 it did again deserve the designation even by 1975 growing to 233.4 inches (5,928 mm), making it the longest four-door hardtop ever built by GM (General Motors), a record unlikely to be broken.  The use of length as a model name was unusual but others have done it, most recently the Maybach (2002-2013), a revived marquee intended by Mercedes-Benz as a competitor for Rolls-Royce & Bentley.  The Maybach was an impressive piece of engineering but its very existence only devalued the Mercedes-Benz brand and was an indication the MBAs who has supplanted the engineers as the company’s dynamic really didn’t have a clue, even about marketing which was supposed to be their forte.  The Maybachs were designated “57” & “62”, the allusion to their length (5.7 & 6.2 metres respectively).  Between 1948-2016, many Land Rovers were given model designation according to their wheelbase (with a bit or rounding up or down for convenience) in inches, thus "80", "88", "110" etc. 

Rear under-run Mansfield bar.

The US authorities did react, federal regulations requiring trucks and trailers be built with under-ride guards (reflectorized metal bars hanging beneath the back-end of trailers) passed in 1953, but the standards were rudimentary and until the incident in 1967, little attention was paid despite similar accidents killing hundreds each year.  The statistics probably tended to get lost among the ever-increasing road-toll, cars of the era being death traps, seat belts and engineering to improve crashworthiness almost unknown.  Predictably, the industry did its math (which took longer in the pre-spreadsheet era) and argued, given that above a certain speed impacts would still cause fatalities, the costs of retro-fitting heavy vehicles would be disproportionate to the number of lives saved or injuries avoided or made less severe.  It's macabre math but it part of business and the most infamous example was Ford's numbers people working out it was projected to be cheaper to pay the costs associated with people being incinerated in rear-ended Pintos than it would be to re-engineer the fuel tank.   

The Mansfield bar works by preventing the nods of the car being slung under the truck, protecting the passenger compartment from impact.

After 1967, although regulations were tightened and enforcement, though patchy, became more rigorous, deaths continued and in the US there are still an average of two-hundred fatalities annually in crashes involving Mansfield Bars.  There are proposals by the Federal Motor Carrier Safety Administration (FMCSA) to include Mansfield Bars on any truck inspection and suggesting to improve the design to something more effective, the devices since 1963 little more than brute force impact barriers and there’s interest in spring-loaded devices which would absorb more of the energy generated in a crash.  Coincidentally, the increasing preference by consumers for higher, bluff-fronted SUVs and light (a relative term, the "light" pick-up trucks popular in the US market regarded as "big" just about everywhere else, even in the Middle East, Australia and New Zealand where they're also sold) trucks has helped improve this aspect or road safety.

There’s concern too about side impacts.  Only a very small numbers of trucks have ever been fitted with any side impact protection and this omission also make corner impacts especially dangerous.  The cost of retro-fitting side (and therefore corner) Mansfield bars to a country’s entire heavy transport fleet would be onerous and it may be practical to phase in any mandatory requirements only over decades.

Truganina, Melbourne, Australia, 4 June, 2025.

Mansfield bars can reduce injuries & fatalities but if the energy in a crash is sufficient (a product of mass, speed and the angle of contact at the point of impact), the consequences will still be catastrophic.  In the early morning of 4 June 2025 in Melbourne, Australia, a Mustang coupé crashed into the right-rear corner of a parked truck, the passenger (sitting in the left front seat of the RHD (right-hand drive) car) killed instantly while the driver was taken to hospital with non-life-threatening injuries.

Truganina, Melbourne, Australia, 4 June, 2025.

The damage sustained by the vehicles was what would be expected in the circumstances, the truck (build on a rigid steel ladder-chassis with a steel-framed freight compartment atop) suffering relatively minor damage while the Mustang’s (built to modern safety standards with the structure outside the passenger compartment designed as a “crumple zone” intended to absorb an impact’s energy before it reaches the occupants) left-front corner substantially was destroyed.  The right-side portion of the Mansfield bar which was hit was torn off in the impact, illustrating the limitations of the technology when speeds are very high, the same reason the car’s “safety cell” was unable to prevent a fatality.

The Seven Ups (1973).

Footage of crashes conducted during testing is illustrative but Hollywood does it better.  In the movie The Seven Ups (1973, produced & directed by Philip D'Antoni (1929-2018), a 1973 Pontiac Ventura Custom, while pursuing a 1973 Pontiac Grand Ville, crashes into a truck with an impact similar to the one in which Jayne Mansfield died; this being Hollywood, the driver emerges bruised & bloodied but intact.  In the movie, the truck is not fitted with a Mansfield bar but if the speed at the point of impact is sufficient, the physics are such that even such a device is unlikely to prevent fatalities.  A re-allocation of a name used on Pontiac’s full-sized (B-Body) line between 1960-1970, the Ventura (1971-1977) was built on the GM (General Motors) compact platform (X-Body), until then exclusive to the Chevrolet Nova (1968-1979 and badged between 1962-1968 as the Chevy II).

Copper

(2) As a color, a metallic, reddish brown.

(3) A slang term for a coin (usually of a smaller denomination) composed of copper, bronze etc.

(4) A slang term for a hedge (archaic).

(5) A slang term for a police or other law-enforcement officer, now usually as the shortened “cop”.

(6) In lepidopterology, any of several butterflies of the family Lycaenidae, as Lycaena hypophleas (American copper), having copper-colored wings spotted and edged with black.

(7) In slang and informal use, a tool or any of the various specialized items made from copper, where the use of copper is either traditional or vital to the function of the item.

(8) In historic UK & Commonwealth use, a large kettle (now usually made of cast iron), used for cooking or to boil the laundry (archaic and functionally extinct); a once popular term for any container made of copper.

(9) To cover, coat, or sheathe with copper.

Pre 1000: From the Middle English coper & copper, from the Old English coper & copor, from the Late Latin cuprum (copper), from the Latin aes Cyprium (literally “Cyprian brass” (ie metal from the island of Cyprus)), from the Ancient Greek Κύπρος (Kúpros) (Cyprus).  It was cognate with the Dutch koper (copper), the Old Norse koparr (copper), the German Kupfer (copper) and the Icelandic kopar (copper).  The alternative spelling coper (a hangover from the Middle English) is obsolete.  Copper & are nouns, verbs & adjectives, copperas is a noun, coppered & coppering are verbs & adjectives and coppery, cupric, cupreous & cuprous are adjectives; the noun plural is coppers.

In the Ancient Greek there was khalkos (ore, copper, bronze), a direct borrowing of the primitive Indo-European word meaning "ore, copper, bronze" and familiar in the Sanskrit ayah and the Latin aes.  In Classical Latin aes originally was used of copper but as technology evolved, this was extended to bronze (its alloy with tin) and because bronze was used much more than pure copper, the word's primary sense shifted to the alloy and a new word evolved for "copper," from the Latin form of the name of the island of Cyprus, where the copper mines were located.  Cyprus being the birthplace of Aphrodite (Venus), this led (in the way mythology adapted to the times) to the association of by alchemists of Aphrodite with copper.  Aes passed into the proto-Germanic where originally no linguistic distinction existed between copper from its alloys while in English it became “ore”.  In Latin vernacular, aes was used also to mean “cash, coin, debt, wages” in many figurative expressions. The chemical symbol Cu is from cuprum, from the Ancient Greek Κύπρος (Kúpros) (Cyprus).

The use to describe coins made of (or appearing to be made of) copper dates from the 1580s while to refer to vessels (jars, tubs, pots etc) made from the metal it came into use in the 1660s, the adjective cupreous (consisting of or containing copper (from the Late Latin cupreus (of copper), from cuprum (an, alternative form of cyprum (copper)) emerging in parallel.   The adjectival use in the sense of “made from or resembling copper” emerged in the 1570, a development from the verb, in use since the 1520s.  The alloy copper-nickel was first used to mint coins in 1728.  The trade of coppersmithing, practiced by the coppersmith (artisan who works in copper), was a creation of the early fourteenth century and was, as was practice at the time, soon used as a surname.  The noun copperplate (also copper-plate) described a "plate of polished copper, engraved and etched" dates from the 1660s and was later used figuratively to describe designs (wallpaper, woodcuts, carvings, carpet etc) with some resemblance to the styled metal.  Perhaps surprisingly, the adjectival sense in the sense of an allusion to the reddish-brown color isn’t documented until the turn of the nineteenth century (“cupric” used thus in 1799 and "copper-colored" after 1804) although it may earlier have been part of one or more oral traditions.

In an example of the way English must seem strange to speakers of more apparently logically languages, the use of “cop” as a slang term for “police or other law-enforcement officer” is a shortening of “copper” but that is etymologically unrelated to the metal, the use of “copper” to describe policemen (at a time all were men” derived from the English “cop”.  The construct was cop (to take, capture, seize) +‎ -er (the agent suffix).  Cop is of uncertain origin but the most likely link is with the Middle English coppen & copen, from the Old English copian (to plunder; pillage; steal) although some etymologists have also suggested the Middle French caper (to capture), from the Latin capiō (to seize, grasp) or the Dutch kapen (to seize, hijack), from the Old Frisian kāpia (to buy), source of the Saterland Frisian koopje and the North Frisian koope.  A perhaps related form was the Middle English copen (to buy), from the Middle Dutch copen.

New York's Statute of Liberty with the copper skin colored as it would have appeared in France, prior to being shipped to the US for erection in  in 1886 (left) and as it appeared decades later, the metal showing the effects of oxidization (right).  

The expression “to cop” was thus used in the sense of “to steal” but also (as a transitive verb) “to (be forced to) take; to receive; to shoulder; to bear, especially blame or punishment for a particular instance of wrongdoing”, hence the expressed notions of “cop the blame”, “cop an injury” etc.  It was the association with crime and violence which in the nineteenth century saw "copper" (one who cops (apprehends) the criminal) adopted in the UK (first documented in 1846) to describe what were then the still relatively novel (in the sense of a structured, publicly-funded force) policemen and as “cop”, the world spread world-wide.  Cop also had a mono-syllabic appeal to many sub-cultures who took up the sense of “to obtain; acquire; purchase”; it was used (1) by drug users to express acquisition of narcotics, (2) among anoraks (train-spotters, plane-spotters, bird-watchers etc) to mark the observation and recording of something unique or at least rare and (3) by those living off immoral earnings (pimps), to speak of the recruitment of a prostitute to the lineup.  There was also the alleged slang form “fair cop”, said to be used by criminals (to cops) when admitting guilt although whether this was as common in real life as it was in the imaginations of crime writers isn’t known although “bent copper” (a corrupt police officer) still enjoys some currency.

JTC Roofing in the UK provided a chart using the Statute of Liberty to illustrate the natural process by which copper gradually changes in color from the original reddish-brown to green, a chemical reaction between the metal and the oxygen in the atmosphere, something known as oxidation.  In an aesthetic sense, the transition to green is part of copper’s charming patina but it’s also functional, providing a protective coating which protects surface deterioration and in this it differs from a ferrous metal like iron which, under oxidation, becomes rusted, the rust eating into the material.  The result can be seen in the light bluish-green copper facades which adorn many copper rooftops and structures and the pallette evolves over years before the familiar green tint achieves a final hue, something influenced also by atmospheric and climatic conditions.

The patination of copper induced by oxidation can be emulated in hair colors: Lindsay Lohan demonstrates. 

Helpfully, World of Chemicals has explained the chemistry.  When in 1886 the Statute of Liberty was assembled and erected after being shipped from France, it was a quite dull brown, reflecting the process of oxidation which had already taken from the metal the shininess which the coppersmiths and engineers would have seen when first working on the pates in Paris and it would take another 30-odd years of weathering before the now familiar color settled.  This patination is fine if a structure for decades remains untouched but in some uses in architecture (especially roofs which are vulnerable to damage), it’s sometimes necessary to replace copper panels which can result in an unsightly patchwork of colors.  For this reason, the industry has developed processes of pre-patination which can render copper panels with specific degrees of patination to match a sample of the damaged item, thus providing a close color-match.

As a courtesy to Lindsay Lohan and other redheads, Harper's Bazaar published Exactly How to Choose the Perfect Lipstick Shade for Redheads which included a list of “dos & don’ts” by celebrity make-up artist Emma Day (b 1974).  Lipstick for redheads is a “special case” because with the overwhelming majority of lipsticks being red, the chance of a jarring clash is greater for redheads and the interplay between skin-tone, hair color and lipstick demands greater attention.  It would of course be simpler were the term “red head” actually to mean “person with red hair” but the hues grown are typically coppers, ambers, gingers, oranges, auburns etc, not color ranges which typically mesh well with most reds, thus the need for expert advice.

Because of its location and the era in which it has stood, the particular path to verdigris (from the French vert-de-gris (literally “green of Greece”)) assumed by the Statute of Liberty was influenced by the unique environmental conditions.  Although the process is linguistically encapsulated as “oxidation”, it's not a simple single reaction between copper and oxygen because the generated green oxide continues to react to make copper carbonates, copper sulphide, and copper sulphate.  Initially, the copper reacts with oxygen from the air in a redox reaction, the metal donating electrons to oxygen, which oxidises the copper and reduces the oxygen, the copper oxide continuing to react with oxygen to form copper oxide.  However, for many of the decades in which the statute stood, the atmosphere contained much sulphur from the burning of coal and this induced another reaction which produced copper sulphide (black) which reacts with atmospheric carbon dioxide and hydroxide ions from water vapour, forming three compounds all of which exist in shades of blue or green.  The speed at which the patina develops and evolution of the colour depends on factors like temperature, humidity and air pollution, not just the presence of oxygen and carbon dioxide and, in another time, in another place, things would have unfolded differently.

Statue of Liberty (1962), silkscreen print by Andy Warhol. 

Andy Warhol (1928-1987) produced a few depictions of the Statute of Liberty, mostly variations of the familiar theme made famous by his prints of Marilyn Monroe (1926–1962) but one with a touch of something original was a silkscreen rendering in 1962 of multiple tiled images in 3D.  At auction by Christies (New York) in 2012, it sold for US$43.8 million, part of a collection of contemporary art that realized an encouraging US$412.3 million, regarded at the time as a sign the market was recovering from the shock of the global financial crisis (GFC); the US Federal Reserve (The Fed) must have been pleased to see all that quantitative easing being spent wisely.  Even so, it didn’t set a record for a Warhol, Eight Elvises sold in a private sale 2008 for a reputed US$100 million although the auction house did throw in a pair of 3D glasses with the catalogue so there was that.  In 2013, another Warhol from 1963 set a pop-art record which stands today, Silver Car Crash (Double Disaster) selling at auction for US$105.4 million.

Acid

Acid (pronounced as-id)

(1) In chemistry, a compound usually having a sour taste and capable of neutralizing alkalis and reddening blue litmus paper, containing hydrogen that can be replaced by a metal or an electropositive group to form a salt, or containing an atom that can accept a pair of electrons from a base. Acids are proton donors that yield hydronium ions in water solution, or electron-pair acceptors that combine with electron-pair donors or bases; having a pH value of less than 7.

(2) In chemistry, any compound which easily donates protons (a Brønsted acid); any of a class of water-soluble compounds, having sour taste, that turn blue litmus red, and react with some metals to liberate hydrogen, and with bases to form salts; any compound that can accept a pair of electrons to form a covalent bond (a Lewis acid).

(3) A substance sour, sharp, or biting to the taste; tart; having the taste of vinegar.

(4) Something, as a remark or piece of writing, that is sharp, sour, or ill-natured.

(5) A slang term for the hallucinogenic drug Lysergic acid diethylamide (LSD).

(6) In metallurgy, noting, pertaining to, or made by a process in which the lining of the furnace, or the slag that is present; functions as an acid in high-temperature reactions in taking electrons from oxide ions: usually a siliceous material, as sand or ganister.

(7) Of or pertaining to an acid; acidic.

(8) In pop music, a genre that is a distortion (as if hallucinogenic) of an existing genre, as in acid house, acid jazz, acid rock etc.

1620-1630: From the French acide, from Latin acidus (sour, sharp, tart (and used also figuratively to suggest "disagreeable” etc)), adjective of state from acere (to be sour, be sharp) and akin to ācer (sharp) & acētum (vinegar), from aceō (I am sour); doublet of agita.  Root was the primitive Indo-European ak (be sharp, rise (out) to a point, pierce).

The figurative use (sour-tempered; acerbic) in English dates from 1775 and came to be applied to intense colors after 1916.  The process of the acid dye was invented in 1888 and used an acid bath. The “acid test” is American English from 1881, originally a quick way to distinguish gold from similar metals by application of nitric acid, it came to be used figuratively (and not always accurately) in the same senses as “litmus test”.  The “Acid drop”, a kind of hard sugar candy flavored with tartaric acid, was first sold in 1835, the noun “drop” applied in the sense of a lozenge.  The noun appeared in the 1690s, derived from the adjective and was originally applied (rather loosely) to just about any substance tasting like vinegar; the more precise parameters defined only in the early eighteenth century as the techniques of modern chemistry came to be refined.  In the chemical sense, the antonym is alkaline.  The term “acid rain” (highly acidic rain caused by atmospheric pollution) was in 1872 coined by Scottish chemist (Robert) Angus Smith (1817–1884) although it wouldn’t be for another hundred years before if came into general use.  Diana, Princess of Wales (1961–1997) coined a nickname for her step-mother, Raine Spencer (1929-2016): Acid Raine.  

Acid as a slang term for the hallucinogenic drug Lysergic acid diethylamide (LSD) dates from 1966.  From the same year “acid rock” was originally a descriptor applied to music performed by those who were tripping on LSD (or what they sounded like suggested they might be) but, as acid rockers, soon applied equally to the audience.  The adjective before long was bolted onto a wide variety of pop music (acid jazz, acid folk etc), acid house from 1988 probably the most enduring as a marketing term.  Not until October 1968 was LSD prohibited in the US by being classified as a Schedule I controlled substance under the Staggers-Dodd Bill which meant it became unlawful to manufacture, possess or distribute the stuff.  This was formalized in 1970 when, as part of Richard Nixon's (1913-1994; US president 1969-1974) "War on Drugs", it was listed as a Schedule 1 substance (those considered to have a high potential for abuse and no accepted medical use) in the Controlled Substances Act (1970). 

LSD-25 Auto.

Cross-breeding has produced many strains of marijuana but there's also cross-breeding in marketing: "LSD-25 Auto" is a brand-name of weed.  The retailers recommend LSD-25 Auto to those who “love purple strains”, praising her “tightly packed trichomes”… “clustered around the hypnotic purple shining buds that have a stacked and long characteristic”.  “Bag appeal” is said to be “on the next level” and able to “blast you into another dimension and keep you there”.  Being “mind-bending and certainly on the trippy side”, she’s said to be “best suited for smokers with a high tolerance to cerebral roller coasters and those who enjoy high concentration levels and spurts of creativity”.  For those still unsure, they caution that “novice smokers should take in moderation”.

Cutaway drawing of limited slip differential (LSD).

LSD is also the abbreviation for the limited slip differential, a device used in motor vehicles which allows a differential’s two output shafts to rotate at different speeds within a defined permissible difference in speed.  LSDs are used to improve traction under extreme conditions and the usual slang is “slippery-diff”.  LSD was also the historic abbreviation for the currency denominations used by UK prior to the decimalization of Sterling in 1971.  Although pre-1971 Sterling (based on there being 12 pennies to the shilling and 20 shillings to the pound) also used guineas, half crowns, threepenny bits, sixpences and florins, LSD referenced just the base units: pounds, shillings and pence.  The abbreviation LSD dates from Ancient Rome when a pound of silver was divided into 240 pence (or denarius) and the Latin currency denominations were librae, solidi, and denarii.  In veterinary science, LSD is also the standard abbreviation for lumpy skin disease, a viral disease of cattle and water buffalo.

Lindsay Lohan in Peter Thomas Roth’s campaign promoting Water Drench Hyaluronic Cloud Hydra-Gel Eye Patches.

The active ingredient in the patches is hyaluronic acid, a gooey, slippery substance produced naturally throughout the body and at its highest concentration in the eyes, joints and skin.  Best visualized as a lubricant, it works by providing a fluid cushion between tissues which would otherwise grind against each other.  As a lubricant, hyaluronic acid has remarkable properties, one teaspoon of the stuff able to absorb and retain some 6 US gallons (22¾ litres) of water, a reason why it’s used in the treatment of dry eyes and is a popular additive in in moisturizing creams, lotions, ointments and serums.  Hyaluronic acid is often produced by fermenting certain types of bacteria (rooster combs (the red, Mohawk-like growth on top of a rooster’s head and face) a common source) something the beauty industry dwells on less than the use to enhance the way skin stretches and flexes, reducing wrinkles.  It said also to be helpful in wound healing and the reduction in scarring.

Because of the popular association science fiction and gaming with toxic, flesh dissolving fluids (sometimes flowing through the veins of aliens) the word “acid” evokes horror in many but the body naturally produces many acids and it depends on these interacting with everything else to ensure good health and acids in many forms are in every diet.  An apple (a typical example containing up to 300 chemicals) for example includes pantothenic acid (B5), citric acid, tartaric acid & acetic acid while its taste depends on the concentration of malic acid.  Pantothenic is a combination of pantoic acid and β-alanine, the name pantohenic from the Greek πάντοθεν (pantothen) (from everywhere), the name chosen by chemists because, at least in tiny quantities, it’s present in almost all foods.  Familiar too is the pain-killer aspirin, now taken by many in low-dose form (100 mg or 1½ grains), a regime first recommended as a blood-thinner for those with certain risk factors for heart disease but later adopted by those impressed with the apparent protection offered against many internal cancers.  To a chemist, what we call the non-steroidal anti-inflammatory drug aspirin is acetylsalicylic acid (usually pronounced uh-seet-l-sal-uh-sil-ik as-id).  

Lysergic acid diethylamide

LSD, known colloquially as acid, is a drug known for its psychological effects. This includes altered awareness of surroundings, perceptions, and feelings as well as sensations and images that seem real though they are not.  It’s thus most often described as a hallucinogenic and the one which first generated a moral-panic although there has never been any evidence to support the stories which circulated telling cautionary tales of users leaping to their deaths from tall buildings, thinking themselves able to fly.  The urban myths persist to this day.  LSD was created in Basel in November, 1938 by Swiss chemist Albert Hofmann (1906–2008).  Dr Hofmann synthesized LSD after examining the constituents of the well-known medicinal plant Drimia maritima (squill) and the fungus ergot, the breakthrough moment apparently his understanding of the chemical structure of the squill's Scilla glycosides but the famous properties were discovered only serendipitously, his pharmaceutical research for a unrelated purpose.  It wasn't until 1943 that Dr Hofmann conducted any research on the possibilities LSD might offer using what he then regarded as side-effects.  In a long-known scientific tradition, he tested it on himself, thus enjoying the first acid-trip.

Having no bad trips, he continued the research and LSD (acronym for the German Lyserg-säure-diäthylamid) was in 1947 introduced as a commercial medication under the trade-name Delysid and intended for various psychiatric uses.  In the 1950s, the CIA thought the drug might be useful for mind control and chemical warfare, their tests conducted on young servicemen and students, usually without anything even close to informed consent.  Its possibilities interested psychiatrists and it was a popular subject in experimental research, the design of many of which would today appall ethics committees and terrify the lawyers.

President Richard Nixon (1913-1994; US president 1969-1974) explaining to congress aspects the message sent to the Congress on 17 June 1971, requesting the appropriation of an additional US$155 million for a “war on drugs”.  Egil Krogh (1939-2020 left) was deputy director of the Domestic Council and Dr Jerome Jaffe (b 1933, right) was hired to lead a new drug strategy and was usually referred to as Nixon’s “drugs tsar”.  Egil Krogh was later jailed for his involvement in the Watergate affair.

The subsequent recreational use in the Western world, an outgrowth of the 1960s counterculture, resulted in its worldwide prohibition in 1971, one of the most obvious casualties of the Nixon administration’s “war on drugs” which has around the world been for fifty-odd years waged with many consequences but little apparent effect on the demand for drugs, supply now at historically high levels, outpacing the increase in population.  Fifty years on, LSD remains popular though the extent of its use varies according to supply which tends to be dictated more by the economics of production and distribution than demand, the illicit drug business really preferring other substances because LSD is not addictive.  Of late there’s been much renewed interest in the possibilities offered by therapeutic hallucinogenics, the encouraging findings in DMT, LSD, mescaline & psilocybin research drawing in venture capital, the odd start-up picking up not only where things were left off in 1971 but working with more recently synthesised compounds.  Their difficulties are less scientific than regulatory.

Notable moments in Acid Rock

Todd Rundgren: A Wizard, a True Star (1973).

It’s not known if most listeners recovered from this but Todd Rundgren (b 1948) probably never did, his subsequent output so discursive that the many audiences he sought and sometimes gained never coalesced into a consistent following.   A Wizard, a True Star is there to be enjoyed as his psychedelic phase; just don’t expect more of the same.

Grateful Dead: Aoxomoxoa (1969).

Anthem of the Sun (1968) cast such a shadow that few dead heads list Aoxomoxoa as the band’s finest but none deny it’s the most psychedelic the Dead ever got in the studio.  The hippie-dippy vibe is of course more on display on many of the live releases (bootlegs and otherwise) but on Aoxomoxoa there are enough of the long, circular guitar lines for any tripper to keep tripping.  Unlike some of the European electronica which would follow, the Dead sound best through speakers rather than headphones but, at the time, the effect of Quadraphonic divided opinion.

The Jimi Hendrix Experience: Electric Ladyland (1968).

Not all of Jimi Hendrix's (1942–1970) Electric Ladyland was as psychedelic as the reputation suggests but, spread over two disks, there was room to move and psychedelia does tinge much of the blues for which it's remembered.  Devoted trippers however resist the epic length Voodoo Chile and go straight to side three of the original vinyl, setting the turntable to repeat.

Spirit: Twelve Dreams of Dr Sardonicus (1970).

Although not released until the era’s historic moment had passed with the implosion of the San Francisco ecosystem which fed the beast, Twelve Dreams Of Dr Sardonicus is the retrospective encapsulation of the psychedelic and is Spirit’s masterpiece.  Lyrically one long, strange trip, it’s also musically playful, mixing (rather than fusing) the most clichéd of the motifs of jazz, pop & rock.  This is acid rock’s period piece.

Pink Floyd: More (1969).

So much has Dark Side of the Moon (1973) loomed over Pink Floyd that their early work is neglected by all but a few.  In some cases the indifference is not undeserved but, influenced by the late Syd Barrett (1946-2006), before they were a staple of FM radio, Pink Floyd were certainly somewhere on the psychedelic spectrum and while The Piper At The Gates Of Dawn (1967) hints at it, their work in a trilogy of film soundtracks, More (1969), Zabriskie Point (1970) & Obscured by Clouds (1972) tracks the path of acid-rock.  The best approach is said to be to watch Zabriskie Point with the sound turned down while the album plays on repeat and a true aficionado will drop some acid a few minutes before putting on the headphones.

Sheryl Crow (b 1962): There goes the neighborhood

Hey let's party
Let's get down
Let's turn the radio on
This is the meltdown
Get out the camera
Take a picture
The drag queens and the freaks
Are all out on the town
And cowboy Jane's in bed
Nursing a swollen head
 
Sunshine Sally and Peter Ustanov
Don't like the scene any how
I dropped acid on a Saturday night
Just to see what the fuss was about
Now there goes the neighborhood
 
The photo chick made to look sickly
Is standing in her panties in the shower
She plays the guitar in the bathroom
While the police dust her mother's plastic flowers
And Schoolboy John's in jail
Making a killing through the U.S. mail
 
Sunshine Sally and Peter Ustanov
Don't like the scene any how
I dropped acid on a Saturday night
Just to see what the fuss was about
Now there goes the neighborhood
 
This is the movie of the screenplay
Of the book about a girl who meets a junkie.
The messenger gets shot down
Just for carrying the message to a flunkie.
We can't be certain who the villans are 'cuz everyone's so pretty
But the afterparty's sure to be a wing-ding as it moves into your city
 
Sunshine Sally and Peter Ustanov
Don't like the scene any how
I dropped acid on a Saturday night
Just to see what the stink was about
Now there goes the neighbourhood.
