Hoop

Hoop (pronounced hoop)

(1) A circular band or ring of metal, wood, or other stiff material.

(2) Such a band for holding together the staves of a cask, tub, barrel etc.

(17) A circular band of metal, wood, or similar material used for forming part of a framework such as an awning or tent.

(18) A quart pot, so called because originally it was bound with hoops, like a barrel (used also as a measure of the portion of the contents measured by the distance between the hoops).

(19) A now obsolete (pre imperial system) measure of capacity, apparently between 1-4 pecks.  (In US customary use, a peck was equal to 8 dry quarts or 16 dry pints (8.80977 litres).  In the Imperial system, it was equal to 2 Imperial gallons or 8 Imperial quarts (9.09218 litres).)

(20) In embroidery, a circular frame used to support the thread.

(21) In sports (usually in the plural) a series of horizontal stripe on the jersey.

1125–1175: From the Middle English hope, hoope & hoop (circular band, flattened ring), from the late Old English hōp (mound, raised land; in combination, circular object), from the Proto-Germanic hōp (circular band, flattened ring) & hōpą (bend, bow, arch (which was related to the Saterland Frisian Houp (hoop), the Dutch hoep (hoop), the Old Church Slavonic кѫпъ (kǫpŭ) (hill, island), the Lithuanian kabẽ (hook) and the Old Norse hóp (bay, inlet)), from the primitive Indo-European kāb- (to bend).  Etymologists conclude the original meaning would have been “curve; ring” but the evolution is murky.  The verb was derived from the noun and emerged in the fifteenth century, apparently from the barrel-making business undertaken by coopers (who handled the timber) and hoopers (who fashioned the steel hoops).  Hoop is a noun & verb, hooper is a noun (the surname Hooper a proper noun), hooped is a verb & adjective hoopless, hooplike & unhooped are adjectives; the noun plural is hoops.

Although it’s clear hoops as playthings for children date back to antiquity, they weren’t again documented in Europe until the 1400s (where they were used in an early form of physiotherapy) and seem not to have been commercially available only after 1792.  The sport of basketball dates from 1891 and the term hoops (both for the physical components and the game itself) was certainly in use by 1893 although oral use may have preceded this.  The use in circuses (a large ring through which performers or animals are trained to jump) was noted in 1793 but there are journals from travelers in Spain, the Middle East and North Africa which confirm the same devices were being used to train military horses as early as the 1100s.  From this, developed the figurative form “jumping through hoops” which was used from circa 1915 to refer to the obstacles which must be overcome in order to proceed (one being forced to perform time-consuming, pointless tasks in order to gain a job, qualify for acceptance to something etc).

Structural engineering: How the hoop skirt is done.

The hoops (circular band serving to expand and shape the skirt of a woman's dress) used in fashion became popular in the 1540s but similar ideas in structural engineering has been used for thousands of years.  Until the twentieth century, the style never really went away but the size of the hoops certainly waxed and waned as tastes shifted.  The hoops were used for both skirts and petticoats and were fabricated variously from ratan, whalebone, bamboo and even steel and sometimes shapes beyond the purely circular were used, notably the bustle-back style which used the same technique of fabric over a framework.  The term hoop-petticoat appears to date from 1711 while the hoop-skirt is documented since 1856.  A hooptie (less commonly as hooptee or hoopty) is US slang for a dilapidated motor vehicle, dating from the 1920s but achieving popularity when used in hip-hop culture during the 1980s.

The hoop snake, a native of the southern US & northern Mexico, was so named in 1784 in recognition of its ability to take its tail in its mouth and roll along like a hoop.  The phrase “cock-a-hoop” (delighted; very happy) was first noted in the sixteenth century and is of unknown origin but may be derived from either (1) the earlier “to set the cock a hoop” (prodigally to live) which implied (literally) “to put a cock on a hoop” (ie, a full measure of grain).  The surname Hooper (maker of hoops, one who hoops casks or tubs) dates from the thirteenth century and was the companion occupation of the cooper who made the barrels.  Hooper & Co (1805) was a UK coach-builder which in the twentieth century moved into the automobile business, catering for the top-end of the market including those supplied to the Royal Mews.  In the 1950s it was noted for its signature “knife-edge” style which, somewhat incongruously, applied one of the motifs of modernity to what was by then an antiquated design idea.  It was also associated with the extravagant Docker Daimlers but it was the end of an era because the move to unitary construction by the manufacturers meant the end for traditional coach-building and their production lines were closed in 1959 although business continued in various forms and in the 1980s, a few one-off Bentleys and Rolls-Royces were made.  Hoopla (also a hoop la) was a coining of US English (originally as houp-la) dating from the 1870s meaning “exclamation accompanying quick movement” and thought derived from the French phrase houp-là (“upsy-daisy” in the English sense), used in Louisiana.  It has come generally to mean “a great fuss”.

The Glasgow-based, Scottish football club Celtic is (along with Rangers) part of an effective duopoly which dominates the Scottish Premiership, the nation’s (FIFA says it’s a country) top-level competition.  The club was founded in 1887 and its first game was a “friendly” against Rangers.  In sport “friendly” is a technical term which means only that no trophy or competition points are at stake and (certainly in the crowd), there is never anything friendly about Celtic-Rangers contests.  As well as taking the majority of the cup competitions, since 1985-1986 either Celtic or Rangers have won each season’s top-flight trophy.  Reflecting their Irish-Catholic traditions, Celtic has always played in green and white and the distinctive hooped shirt was adopted in 1903, gaining them the nickname which endures to this day: The Hoops.

Lindsay Lohan recommends salt & vinegar (S&V) Hula Hoops.

Made from processed potatoes & corn (maize), Hula Hoops are fashioned in the short, hollow cylinders about one inch (25 mm) across.  They were first sold in the UK in 1973 and have been sold (under a variety of brands) in Europe, South America, Asia and throughout the English-speaking world (except North America).  Because the distribution model relied on sea transport  from centralized production facilities, the Hula Hoop business was greatly disrupted by the COVID-19 pandemic and in some cases, supplies to some markets weren't wholly restored until 2022, a problem for HH addicts because apparently, there's nothing else quite like them.  The internet noted Ms Lohan's fondness for salt & vinegar (S&V) but the consensus seem to be the most popular flavor was BBQ Beef (Brown).

Hooters is a US cultural and culinary institution and one of its signature features is the beer being served by a hula-hooping waitress.  Hooters provides an instructional video, performed by Jordan from Georgia.

The staff at Hooters of course use a traditional hula-hooping technique, not only to respect the history but because they pour beer while hooping.  However, for those able to perform in "hands-free" mode, the hoop can be made to rotate in any arc which movements of body-parts permit.

Orthogonal

Orthogonal (pronounced awr-thog-uh-nl)

(1) Of, pertaining to or involving right angles; perpendicular

(2) In mathematics (sometimes as orthographic), pertaining to or involving right angles or perpendiculars.

(3) In mathematics, of a system of real functions defined so that the integral of the product of any two different functions is zero; of a system of complex functions defined so that the integral of the product of a function times the complex conjugate of any other function equals zero.

(4) In mathematics, of two vectors having an inner product equal to zero.

(5) In mathematics, of a linear transformation defined so that the length of a vector under the transformation equals the length of the original vector.

(6) In mathematics (and applied fields such as engineering or statistics), of a square matrix defined so that its product with its transpose results in the identity matrix.

(7) In crystallography, referable to a rectangular set of axes.

(8) Figuratively, something having no bearing on the matter at hand; independent of or irrelevant to another thing or each other.

(9) In art, (1) the descriptor of the lines of perspective which can be mapped onto an image pointing to the vanishing point & (2) in the literature of art criticism a technical term which refers to work consisting exclusively of horizontal or vertical line and thus angles which, if they exist, are right angles.

1565–1575: From (the now obsolete) orthogonium (right triangle), from the French orthogonal, from either the Late Latin orthogōnium & orthogōnālis, from the Latin orthogōnius (right-angled).or directly from the Greek orthogṓnion (neuter) (right-angled), the construct being ortho- + -gōn(ion) + -al.  Ortho- (straight, correct; proper), was from the Ancient Greek ὀρθός (orthós), from the Proto-Hellenic ortwós, from the primitive Indo-European hr̥dwós, from herd- (upright) and was cognate with the Latin arduus and the Sanskrit ऊर्ध्व (ūrdhvá).  The –gon element was from the Ancient Greek γωνία (gōnía) (corner, angle), from the primitive Indo-European ǵónu (knee).  The -al suffix was from the Middle English -al, from the Latin adjectival suffix -ālis, or the French, Middle French and Old French –el & -al.  It was use to denote the sense "of or pertaining to", an adjectival suffix appended (most often to nouns) originally most frequently to words of Latin origin, but since used variously and also was used to form nouns, especially of verbal action.  The alternative form in English remains -ual (-all being obsolete).  Orthogonal is a noun & adjective, orthogonality & orthogonalization are nouns and orthogonally & orthonormal are adverbs; the noun plural is orthogonals.

As adjectives, orthogonal & orthographic are synonymously and the choice is dictated by preference, habit or the rhythm of the text although, to avoid confusion, they probably shouldn’t both be used in the same document.  The Ancient Greek ὀρθογώνιον (orthogṓnion) and the Classical Latin orthogonium originally denoted a rectangle and it was in this sense the words were used by the early mathematicians although the use was later extended to mean a right triangle.  By the twelfth century (especially among engineers and architects) the post-Classical Latin orthogonalis came to mean a right angle or something related to a right angle.  In the modern era, in science and mathematics, derived forms have been coined as required (biorthogonal, psuedo-orthogonal et al) and there’s also the mysterious semiorthogonal which would seem oxymoronic given orthogonal is a description of a mathematically defined absolute.  In figurative use, orthogonal is used to suggest something is unrelated or irrelevant to whatever is being discussed but because it’s so rarely used outside of mathematics, engineering, architecture or art criticism, it’s probably a term to avoid though it may be worth a point or two in Philosophy 101.

Richard Nixon, the Franklins & the Orthogonians

When Richard Nixon (1913-1994; US president 1969-1974) attended Whittier College in California (1930-1934), it was still formally affiliated with the Religious Society of Friends (the Quakers), a link it would maintain until the post-war years.  However, in many ways it was little different to wholly secular institutions in the US (except that one hour a day in chapel was mandatory), including the fraternities and sororities, the still almost exclusively single-sex, student-run societies which were established on many a basis and have evolved variously although a number of the male-only ones often attract attention related to their epic levels of alcohol consumption.  As was the case with many colleges until recent decades, many of those which Richard Nixon found when he arrived had been formed as literary societies and while there were four sororities (for women), there was but one fraternity.

That was the Franklin Society which in 1921 had been the first fraternity founded at Whittier College, beginning as a literary society that based itself on the "virtues" espoused by US founding father and polymath (and confessed Freemason) Benjamin Franklin (1706-1790).  Nixon, then unpolished and obviously a shop-keeper’s son, thought them snobby and elitist, an opinion either formed or reinforced when the Franklins rebuffed attempts to join and readily he accepted the suggestion be assume the presidency of the fraternity formed by other students resentful at being rejected by the Franklins.  This was the Orthogonians, the name (based on the now standard translation “right angles”) meaning “the straight shooters”, their motto an earthy “beans, brains, brawn and bowels”.  The Orthogonians did not enjoy the black tie lifestyle of the Franklins and weren’t invited to the best parties but several of Nixon’s biographers have traced from his fraternity experience many of the characteristics which would remain identifiable throughout this political career.  He learned that in life there are few stars but many supporting players and the man who can align himself with their interests can gain their loyalty, something of real practical value in systems where everyone has one vote; it was the origin of his idea that elections and contests of ideas can be won by being appealing to the “silent majority”, something which would emerge as a political strategy during his presidency.  It taught him also that being hated was no obstacle to political success as long as one was hated by the right people, something he proved by beating the Franklin’s nominee for the position of student body president.  To this day, the Frankin’s website still boasts: “Among those who have been denied membership to this exclusive society is former president Richard Nixon.”  The Orthogoian Society still exists.

The master and the apprentice: Donald Trump and Richard Nixon, Houston, Texas, 1989.  It’s said the subject of Iran was raised in their discussions.

Some biographers have made much of the Franklin-Orthogonian contrast in the making of Nixon the younger.  In Nixonland (2008), Rick Perlstein’s (b 1969) thesis was that between 1965-1972, Nixon crafted a national conflict by exploiting the the mutual fear and hatred between the country’s elite Franklins and the “ordinary people”, the Orthogonians.  Some criticized the approach but Nixonland was a vivid approach to the era in which the divisions in the US became more exposed than they had been for a century and which was a prelude to the cross-cutting cleavages which have for decades characterized the country’s politics.  Nixon didn’t invent the politics of resentment but he expressed them in a language more easily understood by even the unsophisticated and more offensive than ever to those he labeled “the elites”.  In their own ways, to their radically different constituencies, Bernie Sanders (b 1941; senior US senator (Independent, Vermont) since 2007) and Donald Trump (b 1946; US president 2017-2021) are both inheritors of the Nixon legacy, two Franklins telling the Orthogonians they’re here to help.

Superleggera

Superleggera (pronounced soo-per-lee-ghera)

(1) In automotive coach-building, a method of construction which combined a framework of thin steel tubes with aluminum outer panels, producing a lightweight structure.

(2) In recent years, a designation used as a model name to refer to a “lightweight” vehicle even if not a classic superleggera structure.

1935 (a patent for the technique issued in 1936):  From the Italian superleggera (super light) (feminine singular of superleggero), the construct being super- +‎ leggero.  Super was from the Latin super-, from the Proto-Italic super, from the primitive Indo-European upér (over, above) which was cognate with the Ancient Greek ὑπέρ (hupér) (above) and the Proto-Germanic uber (now familiar in English and translated as “over” although this doesn’t wholly convey the sense in Modern German).  Leggero (light in weight, slight, thin) was from the Old French legier, from the Vulgar Latin leviārius, from the Latin levis, from the Proto-Italic leɣis, from the primitive Indo-European hlengwih-, from hléngus, from hleng (lightweight). The cognates included the Sanskrit लघु (laghú), the Ancient Greek ἐλᾰφρός & ἐλᾰχῠ́ς (elaphrós & elakhús) and the Old English lēoht (the ultimate source of the English light).  Superleggera is a noun & adjective; the noun plural is superleggeras (or in the Italian the masculine plural is superleggeri, the feminine plural superleggere).

Carrozzeria Touring and superleggera

It was in 1926 that two Milanese lawyers discussed how bored they were with mundane, if lucrative, legal work and much preferred the exciting world of the automobile, the industry then something like that of IT in the early twenty-first century in that a critical mass of users had been established, growth was consistent and new ventures were coming and going amid a milieu of M&A (mergers & acquisitions).  The lawyers negotiated a controlling interest in Milan-based coachbuilder Carrozzeria Falco, changing the company’s name to Carrozzeria Touring.  Contracts to provide bodywork soon followed including from some of the industry’s major manufacturers including Citroën, Isotta Fraschini & Alfa Romeo and for some time they continued to adopt Falco’s methods which was an adaptation of the “Weymann” system which involved laying fabric over lightweight frames supported by a traditional separate chassis.  Touring produced elegant coachwork of a high quality and attracted the patronage of both Benito Mussolini (1883-1945; Duce (leader) & prime-minister of Italy 1922-1943) and Victor Emmanuel III (1869–1947; King of Italy 1900-1946) although perhaps more influential was the Queen who was often photographed alighting from one of Touring’s large cars, a more imposing sight than the exit of her diminutive husband.

Touring proved innovative in its use of strong, lightweight alloys to support the fabric skins and they enjoyed much success also in applying the technique to aircraft components such as wings and fuselages but during the 1930s with both the military and civilian airlines wanting to fly higher, faster, for longer and in all weather, the shift was beginning towards all-metal construction.  This was an organic evolution of the Weymann technique but the weight and other characteristics of sheet aluminum differed greatly from stretched-fabric and the system needed substantially to be re-engineered and it was the lessons learned from fabricating fuselages which led to Touring developing superleggera, the design patented in 1936.  The essence of superleggera was a skeleton of small diameter tubes which formed a body’s core shape, to which were attached thin aluminum-alloy panels which provided both aerodynamic form and strength.  Compared with earlier methods, as well as being inherently light, the method afforded great flexibility in fashioning shape and Touring took advantage of the properties of the metal to create both complex and flowing curves.  Some of their cars of the era did have lovely lines and in addition to the collaboration with Alfa Romeo which yielded sports cars, gran turismo machines and racing cars, the house attracted business from Lancia, Bianchi and others.

In the post war years, an era in which demand was high and regulations rare, the number of cars built according to the superleggera system increased as Touring licensed the use of its patent to others including Hundon in the US, Pegaso in Spain and Bristol, Aston Martin & Lagonda in England.  Bristol particularly took to the idea because of their long experience with airframes but perhaps the most influential stylistically was the 1948 Ferrari 166 MM Touring barchetta, a charismatic shape which provided a template which would remain recognizable in Ferraris for a quarter-century, the motif of the egg-crate grill still in use today.  While superleggera was unsuited to volume production, for the exclusive ranges at the upper end of the market it was ideal and both Lamborghini and Maseratis emerged built with the technique.  Although the two are sometimes confused because there are visual similarities under the skin, the space-frame method differs in that it can support the whole structural load whereas a superleggera is attached to an existing chassis.

1960 Aston Martin DB4 GT Zagato (left), 1961 Aston Martin DB4 Convertible (centre; the Volante designation wasn't then in use) and 1965 Aston Martin DB5 Saloon.

In the public mind, the most enduring connection was with Aston Martin which was granted a license to use the design and the Superleggera construction method at its Newport Pagnell plant for a fee of £9 for each of the first 500 bodies and £5 for each subsequent unit and the DB4 & DB5 (the latter made famous in the early James Bond films) were both built thus.  However, they represented something of the end of the era because governments were starting to pass laws which demanded road cars attain a certain degree of crash-worthiness, something the superleggera technique couldn’t be adapted conform to without sacrificing the very lightness which was its raison d'etre.  Additionally, the manufacturers were moving swiftly to replace body-on-frame with unit-construction.  Touring attempted to adapt to the changing environment by offering its services as a coach-builder for small, exclusive production runs and made the necessary capital investment but it had become crowded field, the supply of coach-builders exceeding the demand for their skills.  Touring ceased operations in 1966 but four decades on, there was an unexpected revival of the name, the company re-established as Carrozzeria Touring Superleggera, offering automotive design, engineering, coach-building, homologation services, non-automotive industrial design, and the restoration of historic vehicles.  A number of very expensive one-off and limited-production ventures for Maserati, Alfa Romeo and Bentley followed but what attracted most comment was the Sciàdipersia, shown in coupé form at the Geneva Motor Show in 2018, the cabriolet introduced the flowing year.  Based on the underpinnings of the Maserati Grantourismo, although owing no visual debt, it was very much in the tradition of the three Maserati 5000 GTs Touring built in 1959-1960, the first of which had been ordered by the Shah of Iran.  Superleggera however is now just a name with an illustrious history, the method of construction no longer in use and when used as a model designation, it now simply denotes what a literal translation of the Italian suggests: lightweight.

There are obvious visual similarities between the classic superleggera method and the geodesic structure used in airframes and some buildings, most famously the “geodesic dome”.  The imperatives of both were strength both aim to create strong and lightweight structures, but they differ in their specific design and application.  As used in airframes, the geodesic structure consisted of a network of intersecting diagonal braces, creating a lattice framework which distributed loads as evenly as possible while providing a high strength-to-weight ratio.  This was of great significance in military airplanes used in combat because it enhanced their ability better to withstand damage better, the stresses distributed across the structure rather than being restricted to a limited area which could create a point-of-failure.  The geodesic framework was based on geometric principles which had been developed over centuries and typically employed hexagons & triangles to render a structure which was both rigid & light.  Superleggera construction differed in that it involves the creation of a lightweight tubular frame, covered with aluminum body panels of a thinness which wouldn’t have been possible with conventional engineering.  The attraction of the superleggera technique was the (relatively) minimalistic framework supported the skin, optimizing weight reduction without compromising strength.  So, structurally, the difference was the geodesic design used a network of intersecting braces to form a lattice, while the superleggera construction used a tubular frame covered with panels.

React

React (pronounced ree-akt)

(1) To act in response to an agent or influence.

(2) To act reciprocally upon each other, as two things.

(3) To act in opposition, as against some force.

(4) To respond to a stimulus in a particular manner.

(5) In physics, to exert an equal force in the opposite direction to an acting force; to act in a reverse direction or manner, especially so as to return to a prior condition.

(6) In chemistry, to act upon each other; to exercise a reciprocal or a reverse effect, as two or more chemical agents; to act in opposition.

(7) In chemistry, to cause or undergo a chemical reaction.

(8) In the hyphenated form re-act, to act or again perform.

(9) To return an impulse or impression; in Internet use, to post a reaction (now often in the form of an emoji), indicating how one feels about a posted message.

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 et al 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."

1250–1300: From the Middle English, from the Old French metal (metal; material, substance, stuff), from the Classical Latin metallum (quarry, mine, product of a mine, metal), from the Ancient Greek μέταλλον (métallon) (mine, quarry, ore).  The Greek work picked up the sense of “metal” only in post-classical texts, via the notion of "what is got by mining”; the original meaning was "mine, quarry-pit," probably a back-formation from metalleuein "to mine, to quarry," a word of unknown origin which may be related to metallan "to seek after" but there’s no evidence in support and it’s thought derived from a pre-Greek source because of the presence of -αλλο- (-allo-).  Metal is a noun, verb & adjective and metallic is a noun & adjective; the noun plural is metals.

In the West, what defined a metal was based on the metals known from antiquity: gold, silver, copper, iron, lead, and tin.  The adjectival form (or or covered with metal) emerged in the late fourteenth century reflecting the advances in metallurgy.  The term metalwork is attested from 1724 and has been used to describe both functional and decorative endeavours and is a common title in technical education (al la woodwork).

The use to describe a variety of loud forms of popular music (heavy; thrash; power; gothic; doom; twisted; black; molten & death-metal (there may be others, it’s hard to tell)) began with heavy metal, the term coming into general use circa 1970 to describe a genre which had evolved since what came retrospectively to be called the proto-metal pieces of the 1950s such as Link Wray's Rumble.  As a shortened form, “metal” appears to be used properly to reference only heavy metal, presumably because it came first, the other forms almost always identified with the modifier.  The use in popular music seems to have been picked up from counterculture literature, William S Burroughs (1914-1997) using the phrase "heavy metal kid" in the 1962 novel The Soft Machine.  That was not a musical reference but in the subsequent Nova Express (1964), extended the use to a metaphor for drug use and from there, adoption in somewhere in popular culture was probably inevitable; it was the 1960s.

The lightness and heaviness of naturally occurring metals has been noted since pre-historic times, probably because of the interest in the malleability of materials which might be used to craft metal ornaments, tools and weapons and until the early nineteenth century, all known metals had relatively high densities, indeed that very quality of heaviness was thought a distinguishing characteristic which defined metals.  However, beginning in 1809, lighter metals such as sodium and potassium were isolated, their low densities demanding a definitional re-think and it was proposed they be categorised as “metalloids” but instead, that was reserved to later refer to a variety of non-metallic elements.

The term "heavy metal" seems first to have been used by German chemist Professor Leopold Gmelin (1788-1853) in an 1817 paper in which he divided the elements into non-metals, light metals, and heavy metals, based on relative density.  Later, “heavy metal” would be associated with elements with a high atomic weight or high atomic number and it is sometimes used interchangeably with the term “heavy element” although, two centuries on, there is criticism of the very usefulness of the now classical categories, the suggestion being they’ve become so diverse as to be meaningless.  Despite that, “heavy metal” in particular remains frequently used in both scientific and popular literature, the latter most often without any definitional rigor.  By comparison, presumably because their less associated with environmental pollution, “light metal” appears most often in association with metal trading, referring usually to aluminium, magnesium, beryllium, titanium and lithium.

The cosmological periodic table.  Chemists do at least agree on what metals are, heavy or otherwise.  Astronomers consider any element heavier than helium to be a metal, the distinction based on whether an element was created directly after the Big Bang (hydrogen and helium) or instead formed through subsequent nuclear reactions.  In the world of cosmology this is well understood but it can cause confusion among a general audience because it means elements such as carbon and oxygen are treated as metals, a most unfamiliar concept.

To astronomers, the production of metals is a consequence of stellar evolution.  Although metals lighter than iron are produced in the interiors of stars through nuclear fusion reactions, only a very small fraction escape (through stellar winds or thermal pulsations) to be incorporated into new stars.  For this reason, the majority of the metals found in the Universe are produced and expelled in the supernova explosions that mark the end for many stars.  This gradual processing of hydrogen and helium into heavier elements through successive generations of stars means that the metallicity of stars (the fraction of the mass of the star in the form of metals) varies.  Very old stars which formed from the almost pristine material of the Big Bang contain almost no metals, while later generations of stars can have up to 5% of their mass in the form of metals.  The percentage of metals in our star (the Sun) is around 2%, indicating it’s a later generation star.

When it comes to money, and not just with precious metals like gold, the choice of metal matters much; aluminum can become quite precious.

1950 Jaguar XK120 (chassis: 670165 (aluminum body))

Jaguar went to the 1948 London Motor Show thinking their big announcement would be the new XK engine, the twin-cam straight-six which faithfully would serve the line for the next forty-four years.  What instead stole the show was the test-bed, the roadster in which it was installed.  It was a sensation, the reaction convincing Jaguar's management to put it into production as the XK120.  However, tooling-up a production-line, even for a relatively low-volume sports car, takes time so the first 242 XK120s were hand-built with aluminum bodies affixed to an ash frame atop a steel chassis substantially shared with an existing model.  By 1950, the factory was ready for mass production and all subsequent XK120s were made with pressed-steel bodies although the doors, bonnet, and boot lid continued to use aluminum; the later cars weigh an additional 112 lb (51 kg).  All the aluminum-bodied cars were open two seaters (OTS (roadster)) and most were destined for the North American market, only fifty-eight being built with right-hand drive.  The most desirable of the XK120s, the record price for a road car at auction is US$396,000, realised in 2016.  Cars with a competition history have attracted more, a 1951 Roadster campaigned by the Scottish race team Ecurie Ecosse, sold for £707,100 in 2015 while the 1954 (steel) Competition Roadster that won its class at the Alpine Rally brought £365,500 in the same year.

1955 Mercedes-Benz 300SL (chassis: 550028 (aluminum body))

Intended for those planning to use the things in competition, the aluminum body for the 300SL gullwing was a regular production option, albeit a not inexpensive one although, given the processes required, it may have been a bargain.  Reducing weight by 215 lb (80 kg), the aluminum bodies were hand-crafted in the motorsports department in Untertürkheim and then mounted on the spaceframes sent from the Sindelfingen factory.  Of the 1400 gullwings, only 29 were built in aluminum, 26 of 855 in 1955 and 3 of 308 in 1956 so the option was taken-up only by two percent of customers.

Adding to the desirability of the lightweights are the other modifications the factory made to improve competitiveness against the mostly British and Italian opposition.  Plexiglass windows, vented brake drums and stiffer springs were in the package, along with the Sonderteile (special parts (NSL)) engine with tweaked fuel-injection and a more aggressive camshaft, gaining fifteen horsepower.  Curiously, one option intended for use in motorsport actually added a little weight: the Rudge wheels, the seconds the knock-off hubs saved in the pits said to be worth the slight increase.  Available for any gullwing, the Rudge wheels are one of the desirable features, like the fitted luggage, tool kit and factory documents, the presence and condition of which attract a premium at sale.  For some years, the record price at auction for one of these was the US$4.62 million for a 1955 model, paid in 2012 for a car which in 1980 been bought by a German collector for US$57,000.  A new mark was set in 2022 at RM Sotheby's January auction at Scottsdale's Arizona Biltmore Resort when one crossed the block for US$6,825,000.
