Batwing

Batwing (pronounced bat-wing)

(1) In zoology, the wing of a bat (and, informally, related creatures).

(2) In entomology, several South or Southeast Asian species of tailless dark swallowtail butterflies in the genus Atrophaneura.

(3) An object or design formed or shaped in a way resembling the extended wing of a bat.

(4) In architecture, as “batwing doors”, pairs of swinging doors which typically do not lock nor cover the full vertical range of the doorway (leaving a large gap at the top and bottom), common as entrances to commercial kitchens and in bars.  It was the US industry in the mid-1950s which adopted “batwing doors” to replace “saloon doors” because there was some “middle class resistance” to the association with such establishments; it was a in time which rising prosperity had made mass market interior decorating a thing, hence the re-branding.

(5) In fashion, a garment or part of a garment resembling or conceived of as resembling the wing of a bat, applied usually to a loose, long sleeve (some flaring out, some with a tight wrist and known also as the “magyar sleeve”) but also to hem-lines.

(6) In hairdressing, a variation of the pigtail (in which the tied hair extends from the scalp at close to 90^o before cascading) in which the tied hair extends from the scalp upwards at an acute angle before cascading.  Batwings can be single ties but more typically appear symmetrically to the sides, in emulation of the wings of a bat.

(6) In physical training, an exercise routine or posture on the stomach wherein a dumbbell row or lateral raise is performed.

(7) In slang, an area of flabby fat under a person's arms (known in some places as “tuck shop lady’s arms).

(8) In automotive design, a type of rear fin which extended laterally rather than upwards.

1955–1960: The construct was bat + wing.  Bat (in the sense of the small flying mammal) dates from the late 1570s and is thought to be from a Scandinavian source, possibly the dialectal Swedish natt-batta, a variant of the Old Swedish natt-bakka (night-bat).  It replaced the Middle English bake & bak, from balke & blake, also from a Scandinavian source.  The related Nordic forms included the dialectal Swedish natt-blacka and the Old Icelandic ledhr-blaka (bat), the construct being ledhr (skin, leather) + blaka (flutter) and understood in the vernacular as “leather flapper”, the sense something like the later Old Danish nathbakkæ (literally “night-flapper”).  The earlier use (to describe a club, staff etc) dated from the turn of the thirteenth century and was from the Middle English noun bat, bot & batte, from the Old English batt which may have been from Celtic (the Irish & Scots Gaelic bat & bata meant “staff, cudgel”.  The Middle English verb batten, came partly from the noun, influenced by the Old French batre (batter).  Wing dates from the mid-twelfth century and was from the Middle English plural nouns winge & wenge, from the Old Danish wingæ (the other Nordic forms including the Norwegian & Swedish vinge and the Old Norse vǣngr (wing of a flying animal, wing of a building)).  In the Old Norse, the architectural sense of “a building’s wing” extended to nautical use, a vængi a “ship's cabin”.  The Nordic forms came from the Proto-Germanic wēingijaz, from the primitive Indo-European hweh- (to blow (hence the connection with “flapping” & “wind”).  The cognates included the Danish vinge (wing), the Swedish vinge (wing) and the Icelandic vængur (wing).  In English, “wing” came to replace the Middle English fither, from the Old English fiþre, from the Proto-Germanic fiþriją), which merged with the Middle English fether (from Old English feþer, from Proto-Germanic feþrō).  The spellings bat wing & bat-wing are also used.  Batwing is a noun and adjective, batwinged & batwingish are adjectives; the noun plural is batwings.

Alfa Romeo BAT 5 (1953, left), BAT 7 (1954, centre) and BAT 9 (1955, right), designed by Franco Scaglione (1916–1993).

The Alfa Romeo BAT (Berlina Aerodinamica Tecnica, best translated as “exploration of aerodynamic principles in cars”) concept cars were among the most stylistically adventurous (and aerodynamically successful) of the transatlantic movement in the 1950s which focused on applying the lessons learned from progress in aeronautics during World War II (1939-1945).  The tail fin had been seen as early as the 1920s and their role in enhancing straight-line stability was imported directly from aircraft design but on the road they’d tended to be single, upright structures, best remembered from the use in the pre-war Czechoslovakian Tatras, intriguing things which, configured with a rear-mounted V8 engine, at speed needed a “stabilizing fin” more than most.  However, it was in the 1950s, when such publicity was afforded to jet aircraft, rockets & missiles, that designers took a renewed interest in fins & wings.  In the US, they quickly became extravagances, divorced from any functional relationship to fluid dynamics much beyond the merely coincidental but for Europeans, for whom fuel was more expensive and incomes lower, it was understood aerodynamics alone could improve both a vehicle’s economy and its performance.

Batwings: A grey-headed flying fox.

The performance of the trio was, by contemporary standards, remarkable, all able to attain in excess of 200 km/h (125 mph), despite being powered by a relatively small 1.9 litre (115 cubic inch) engine, albeit one fitted with double overhead camshafts (DOHC).  The wings (the BAT acronym for the cars was opportunistic) were just one part on a design which in all aspects was intended to optimize air-flow and although even at the time there were cars with smaller frontal areas, the BATs gained much of their advantage from the lowering of the front coachwork and the drag coefficient (CD) of the three ranged from 0.19-0.23, impressive even today.  It’s on BAT 7 that the batwing motif is most pronounced, the wings extending as a single structure from the base of the A-pillar, at the rear tilting and sweeping in an arc towards the centre-line.  When the metalworkers in the coach-building house first saw the design, their reaction was something like that of the structural engineers on first viewing the “sails” on the blueprints of Jørn Utzon’s (1918–2008) Sydney Opera House but they rose to the occasion.  The design would never have been suitable for mass-production; the famous fins on the US cars of the era were not only simpler structures but also designed in a way which accommodated the relatively “lose” manufacturing tolerances which permitted them being built quickly and at scale.  Perhaps tellingly, BAT 9 appeared with appendages less batwing-like and more attuned to the way Detroit was doing things.

It's the batwings which made BAT 7 the most memorable of the three and in 2008, Carrozzeria Bertone (builders of the original trio) built the Alfa Romeo BAT 11dk prototype, a conceptual rendering in clay, Styrofoam & filler, designed to use the underpinnings of the Alfa Romeo 8C Competizione.  Commissioned by a former owner of BAT 7, the Global Financial Crisis (GFC) scuttled its appearance at the Geneva Motors Show and certainly any prospect of a small production run or even a one-off creation.

Misty was a weekly British comic magazine for girls which, unusually, was found also to enjoy a significant male readership.  Published UK house Fleetway, it existed only between 1978-1980 although Misty Annual appeared until 1986.  The cover always featured the eponymous, raven haired beauty.  Befitting its theme, bats often featured in the artwork.

Lindsay Lohan in Anger Management (2013) demonstrates the batwing (left), defined by the tied hair extending upwards from the scalp before cascading, as distinct from the “pig tail” (centre) which extends from the scalp at close to 90^o before cascading.  Batwings can be single ties (centred or asymmetric) but more typically appear symmetrically to the sides, in emulation of the wings of a bat.  There are also batwing hair clips (right), also called “batwing hair claws” which is more evocative.

Chevrolet Bel Air: 1957 (left), 1958 (centre) and 1959 (right).

The 1959-1960 Chevrolets quickly picked up the nickname “batwing” and richly it was deserved; there was nothing like them at the time and there’s been nothing since.  The 1959 range actually had a strange and rushed gestation.  The fins on the 1955-1956-1957 cars (the so-called “tri-five Chevies”) had grown upwards in the fashion of the time but the corporation decided something different was needed and for 1958 chose baroque, the embryonic batwings obvious now but it was only when the next year’s model was released they would be understood thus.  The reason the General Motors (GM) 1958 body shape would last only one season was that at time it suffered by comparison with the sleek Chryslers; it was thought frumpy and even bloated and that it was released into that year’s short but sharp recession, didn’t help. The re-design for 1959 had its flaws (many of which (including toning down the batwings) were fixed for 1960) but it could never have been called “frumpy” and the “cats eye” taillights are admired even today.  Still the market didn’t respond as GM would have liked and the batwings soon flew off; by 1963 the Chevrolet was so blandly inoffensive it was being described as “a little bit like every car ever built”.  It proved a great success.

For 1960, Chevrolet made the batwings a little less “batwingish” and the idea travelled across the Atlantic, Ford in the UK applying the scaled-down motif to their Ford Consul Classic (1961-1963) and Consul Capri (1961-1964), the latter a two-door coupé which the company wanted to be thought of as a “co-respondent's car” (ie the sort of rakish design which would appeal to the sort of chap who slept with other men’s wives, later to be named as the “co-respondent” in divorce proceedings).  Whether or not the “batwingettes” played a part isn’t known but neither the Classic nor the Capri were successful.

Heptadecaphobia

Heptadecaphobia (pronounced hepp-tah-dech-ah-foh-bee-uh)

Fear of the number 17.

1700s: The construct was the Ancient Greek δεκαεπτά (dekaepta) (seventeen) + φόβος (phobos).  The alternative form is septadecaphobia, troubling some the purists because they regard it as a Greek-Latin mongrel, the construct being the Latin septem (seven) + deca, from the Latin decas (ten), from the Ancient Greek δεκάς (dekás) (ten) + the Ancient Greek φόβος) (phobos) (fear).  Heptadecaphobia deconstructs as hepta- “seven” + deca (ten) + phobos.  The suffix -phobia (fear of a specific thing; hate, dislike, or repression of a specific thing) was from the New Latin, from the Classical Latin, from the Ancient Greek -φοβία (-phobía) and was used to form nouns meaning fear of a specific thing (the idea of a hatred came later).  Purists use the spelling heptadekaphobia to avid the mix.

There are a variety of theories to account for the Italian superstition which had rendered 17 the national “unlucky number”.  The most accepted is that in Roman numerals 17 is XVII which, anagrammatically, translates to VIXI (Latin for “I have lived” (the first-person singular perfect active indicative of vīvō (to live; to be alive)), understood in the vernacular as “my life is over”.  That would have been ominous enough but Romans noted also that Osiris, the Egyptian god of, inter alia, life, death, the afterlife and resurrection, had died on the 17th day of the month, 17 thus obviously a “death number” to the logical Roman mind and the worst 17th days of the month were those which coincided with a full moon, an intensifier in the same sense that in the West the conjunction leading to a Friday the 13th is so threatening.  Mashing up the numerical superstitions, that 17 is an “unlucky number” shouldn’t be surprising because it’s the sum of 13 + 4, the latter being the most dreaded number in much of East Asia.

Just because a “fear of a number” is listed somewhere as a “phobia” doesn’t mean the condition has much of a clinical history or even that a single case is to be found in the literature; many may have been coined just for linguistic fun and students in classics departments have been set assessment questions like “In Greek, construct the word meaning “fear of the number 71” (the correct answer being “hebdomekontahenophobia”).  Some are well documented such as tetraphobia (fear of 4) which is so prevalent in East Asia it compelled BMW to revise the release strategy of the “4 Series” cars and triskaidekaphobia (fear of 13) which has such a history in the West it’s common still for hotels not to have a thirteenth floor or rooms which include “13”, something which in the pre-digital age was a charming quirk but when things were computerized added a needless complication.  The use of the actual number is important because in such a hotel the “14^th” floor is of course the 13^th (in the architectural sense) but there’s little to suggest there’s ever been resistance from guests being allocated room 1414.

Some number phobias are quite specific: Rooted in the folklore of Australian cricket is a supposed association of the number 87 with something bad (typically a batter being dismissed) although it seems purely anecdotal and more than one statistical analysis (cricket is all about numbers) has concluded there's nothing “of statistical significance” to be found and there’s little to suggest players take the matter seriously.  One English umpire famously had “a routine” associated with the score reaching a “repunit” (a portmanteau (or blended) word, the construct being re(eated) +‎ unit) (eg 111, 222, 333 etc) but that was more fetish than phobia.

No fear of 17: Some Lindsay Lohan Seventeen magazine covers.  Targeted at the female market (age rage 12-18), the US edition of Seventeen is now predominately an on-line publication, printed only as irregular "special, stand-alone issues" but a number of editions in India and the Far East continue in the traditional format. 

Other illustrative number phobias include oudenophobia (fear of 0), (trypophobia (fear of holes) said to sometimes be the companion condition), henophobia (fear of 1) (which compels sufferer to avoid being associated with “doing something once”, being the “first in the group” etc) , heptaphobia (fear of 7) (cross-culturally, a number also with many positive associations), eikosiheptaphobia (fear of 27) (a pop-culture thing which arose in the early 1970s when a number of rock stars died messy, drug-related deaths at 27), tessarakontadyophobia (fear of 42) (which may have spiked in patients after the publication of Douglas Adams’ (1952–2001) Hitchhiker's Guide to the Galaxy (1979-1992), enenekontenneaphobia (fear of 99) (thought not related to the Get Smart TV series of the 1960s), tetrakosioeikosiphobia (fear of 420) (the syndrome restricted presumably to weed-smokers in the US), the well-documented hexakosioihexekontahexaphobia (fear of 666), heftakosioitessarakontaheptaphobia (fear of 747) (though with the withdrawal from passenger service of the tough, reliable (four engines and made of metal) Boeing 747 and their replacement by twin-engined machines made increasingly with composites and packed with lithium-ion batteries, a more common fear may be “not flying on a 747”).  Enniakosioihendecaphobia (fear of 911) (presumably, in the US, sometimes a co-morbidity with tetrakosioeikosiphobia or suffered by those with a bad experience with a pre-modern Porsche 911 which, in inexpert hands, could behave as one would expect of a very powerful Volkswagen Beetle) and the rare condition nongentiseptuagintatrestrillionsescentiquinquagintanovemmiliacentumtredecimdeciesoctingentivigintiquattuormiliatrecentiphobia (fear of 973,659,113,824,315) (that one created presumably by someone determined to prove it could be done). There’s also compustitusnumerophobia (fear of composite numbers), meganumerophobia (fear of large numbers), imparnumerophobia (fear of odd numbers), omalonumerophobia (fear of even numbers), piphobia (fear of pi), phiphobia (fear of the golden ratio), primonumerophobia (fear of prime numbers), paranumerophobia (fear of irrational numbers), neganumerophobia (fear of negative numbers) and decadisophobia (fear of decimals).  The marvellous Wiki Fandom site and The Phobia List are among the internet’s best curated collection of phobias.

The only one which debatably can’t exist is neonumerophobia (fear of new numbers) because, given the nature of infinity, there can be no “new numbers” although, subjectively, a number could be “new” to an individual so there may be a need.  Sceptical though mathematicians are likely to be, the notion of the “new number” has (in various ways) been explored in fiction including by science fiction (SF or SciFi) author & engineer Robert A Heinlein (1907–1988) in The Number of the Beast (1980), written during his “later period”.  More challenging was Flatland: A Romance of Many Dimensions by English schoolmaster & Anglican priest Edwin Abbott Abbott (1838–1926) which was published under the pseudonym “A Square”, the layer of irony in that choice revealed as the protagonist begins to explore dimensions beyond his two-dimensional world (in Victorian England).  Feminists note also Ursula K Le Guin’s (1929–2018) The Left Hand of Darkness (1969) in which was created an entirely new numerical system of “genderless" numbers”.  That would induce fear in many.

Lindsay Lohan's cover of Edge of Seventeen appeared on the album A Little More Personal (2005).  Written by Stevie Nicks (b 1948), it appeared originally on her debut solo studio album Bella Donna (1981).

In entymology, there are insects with no fear of the number 17.  In the US, the so-called “periodical cicadas” (like those of the genus Magicicada) exist in a 17 year life cycle, something thought to confer a number of evolutionary advantages, all tied directly to the unique timing of their mass emergence: (1) The predator satiation strategy: The creatures emerge in massive numbers (in the billions), their sheer volume meaning it’s physically impossible for predators (both small mammals & birds) to eat enough of them to threaten the survival of the species. (2) Prime number cycles: Insects are presumed to be unaware of the nature of prime numbers but 17 is a prime number and there are also periodic cicadas with a 13 year cycle.  The 13 (Brood XIX) & 17-year (Brood X) periodic cicadas do sometimes emerge in the same season but, being prime numbers, it’s a rare event, the numbers' least common multiple (LCM) being 221 years; the last time the two cicadas emerged together was in 1868 and the next such even is thus expected in 2089.  The infrequency in overlap helps maintain the effectiveness of the predator avoidance strategies, the predators typically having shorter (2-year, 5-year etc) cycles which don’t synchronize with the cicadas' emergence, reducing chances a predator will evolve to specialize in feeding on periodical cicadas. (3) Avoidance of Climate Variability: By remaining underground for 17 years, historically, periodical cicadas avoided frequent climate changes or short-term ecological disasters like droughts or forest fires. The long underground nymph stage also allows them to feed consistently over many years and emerge when the environment is more favorable for reproduction.  Etymologists and biological statisticians are modelling scenarios under which various types of accelerated climate change are being studied to try to understand how the periodic cicadas (which evolved under “natural” climate change) may be affected. (4) Genetic Isolation: Historically, the unusually extended period between emergences has isolated different broods of cicadas, reducing interbreeding and promoting genetic diversity over time, helping to maintain healthy populations over multiple life-cycles.

In automotive manufacturing, there was nothing unusual about unique models being produced for the Italian domestic market, the most common trick being versions with engines displacing less than 2.0 litres to take advantage of the substantially lower tax regime imposed below that mark.  Thus Ferrari (1975-1981) and Lamborghini (1974-1977) made available 2.0 litre V8s (usually variously in 2.5 & 3.0 litre displacements), Maserati a 2.0 V6 (a 3.0 in the Maserati Merak (1972-1983) although it appeared in 2.7 & 3.0 litre form in the intriguing but doomed Citroën SM (1970-1975)) and Mercedes-Benz created a number of one-off 2.0 litre models in the W124 range (1974-1977) exclusive to the Italian domestic market (although an unrelated series of 2.0 litre cars was also sold in India).

US advertisement for the Renault 17 (1974), the name Gordini adopted as a "re-brand" of the top-of-the-range 17TS,  Gordini was a French sports car producer and tuning house, absorbed by Renault in 1968, the name from time-to-time used for high-performance variants of various Renault models.

One special change for the Italian market was a nod to the national heptadecaphobia, the car known in the rest of the world (RoW) as the Renault 17 (1971-1979) sold in Italy as the R177.  For the 17, Renault took the approach which had delivered great profits: use the underpinnings of mundane mass-produced family cars with a sexy new body draped atop.  Thus in the US the Ford Falcon begat the Mustang and in Europe Ford got the Capri from the Taunus/Cortina duo.  Opel’s swoopy GT was (most improbably) underneath just a Kadett.  It wasn’t only the mass-market operators which used the technique because in the mid 1950s, Mercedes-Benz understood the appeal of the style of the 300 SL (W198, 1954-1957) was limited by the high price which was a product of the exotic engineering (the space-frame, gullwing doors, dry sump and the then novel mechanical fuel-injection), the solution being to re-purpose the platform of the W120, the small, austere sedan which helped the company restore its fortunes in the post-war years before the Wirtschaftswunder (economic miracle) was celebrated in 1959 with the exuberance of the Heckflosse (tailfin) cars (1959-1968).  On the W120 platform was built the 190 SL (W121, 1955-1963), an elegant (it not especially rapid) little roadster which quickly became a trans-Atlantic favourite, particularly among what used to be called the “women’s market”.

Only in Italy: The Renault 177.

Using the same formula, the Renault 17 was built on the underpinnings of the Renault 12, a remarkably durable platform, introduced in 1979 and, in one form or another, manufactured or assembled in more than a dozen countries, the last not produced until 2006.  Like the Ford Capri, the 17 was relatively cheap to develop because so much was merely re-purposed but for a variety of reasons, it never managed to come close to match the sales of the wildly successful Ford, front wheel drive (FWD) not then accepted as something “sporty” and Renault's implementation on the 17 was never adaptable to the new understanding of the concept validated by FWD machines such Volkswagen’s Sirocco GTi & Golf GTi.  Like most of the world, the Italians never warmed to the 17 but presumably the reception would have been even more muted had not, in deference to the national superstition about the number 17, the name been changed to “Renault 177”, the cheaper companion model continuing to use the RoW label: Renault 15.

Philadelphus

Philadelphus (pronounced fil-ah-del-fiss)

(1) Any shrub of the temperate genus Philadelphus, cultivated for their strongly scented showy flowers (family Hydrangeaceae).

(2) As Philadelphus coronaries (mock orange), a deciduous, early summer-flowering shrub with arching branches that bear racemes of richly scented, cup-shaped, pure white flowers in profusion with finely toothed, bright green foliage.  The plant is grown for its ornamental value.

(3) A male given name with origins in the Ancient Greek.

1600s (in botanical use): From the Ancient Greek Φιλάδελφος (Philádelphos) (brotherly love) & philadelphon (loving one’s brother).  Philadelphus is a proper noun.

Philadelphus coronaries (mock orange) in flower.

The mock orange plant has long been valued for its decorative and functional properties.  Thomas Jefferson (1743–1826; US president 1801-1809) was a keen gardener and horticulturalist of some note and on 19 April 1807 noted in his “garden book”: “Planted 9 Philadelphus coronarium, Mock orange in the 4 circular beds of shrubs at the 4 corners of the house.”  Although the origin is uncertain, biologists suspect the strong growing, medium-sized shrub is native either to northern Italy, Austria & Central Romania or Central & North America and Asia; in Europe & North America it has been cultivated at least the sixteenth century.  Before modern standards of taxonomy were codified in the eighteenth century, the plant was classified under the genus Syringa (covering the species of flowering woody plants in the olive family or Oleaceae (commonly called lilacs) and a typically comprehensive description was recorded by Lady (Jean) Skipwith (circa 1748–1826), a Virginia plantation owner and manager still celebrated among botanists for her extensive garden, botanical manuscript notes, and library, the latter reputedly the largest at the time assembled by a woman.  Lady Skipwith called the plant a “Syringa or mock orange” while the US naturalist, explorer & explorer William Bartram (1739–1823) preferred the former, reflecting a scientist’s reverence for anything Greek or Latin.  Syringa was from the stem of the Latin syrinx, from the Ancient Greek σῦριγξ (sûrinx) (shepherd's pipe, quill), the name reflecting the use of the plant's hollow stem to make pipes, flutes & tube.  In modern use, “Mock Orange” tends to be preferred by most, the name derived from the fragrance of the flowers being so reminiscent of orange blossoms.  The origin of the scientific name “Philadelphus” (first applied in the early seventeenth century) is attributed usually to being a tribute to Ptolemy II Philadelphus (Ptolemaîos Philádelphos (Πτολεμαῖος Φιλάδελφος in the Ancient Greek) 309-246 BC, pharaoh (king) of Ptolemaic Egypt (284-246 BC), said to be a keen gardener (which can be translated as “he kept many slaves to tend his gardens”).

The literal translation of the Greek philadelphon was “loving one’s brother”, something used in the sense of “brotherhood of man” as well as when referring to family relationships.  For the pharaoh, the use was a little more nuanced because, after some earlier marital problems, he married his older sister Arsinoe II (316-circa 269 BC).  This appalled the Greeks who condemned the arrangement as incestuous and the couple thus picked up the appellation Philadelphoi (Φιλάδελφοι in the Koinē Greek (sibling-lovers)).  Historians however are inclined to be forgiving and suggest the union was purely for administrative convenience, Egyptian political & dynastic struggles as gut-wrenching as anywhere and there’s no evidence the marriage was ever consummated.  Just to make sure there was the appropriately regal gloss, the spin doctors of the royal court circulated documents citing earlier such marriages between the gods (such as Zeus & Hera).  It certainly set a precedent and the intra-family model was followed by a number of later Ptolemaic monarchs and the practice didn’t end.  The scandalous marriage of Heraclius (circa 575–641; Byzantine emperor 610-641) to his youthful niece Martina resulted in her becoming “the most hated woman in Constantinople” and it was a union certainly consummated for “of the nine children she bore her husband, only three were healthy, the rest either deformed or died in infancy.”

The Philadelphi corridor

The Latin proper noun Philadelphi was the genitive/locative singular of Philadelphus.  In 2024 use spiked because the Israel Defense Forces (IDF) use “Philadelphi Corridor” as military code for the narrow (14 km (9 miles) long & 100 m (110 yards) wide) stretch of land used to separate the Gaza Strip from Egypt; it runs from the Mediterranean coast to the Kerem Shalom crossing with Israel and includes the Rafah crossing into Egypt.  The IDF created the corridor (from Gaza territory) as a “buffer zone” (or “cordon sanitaire”), ostensibly to prevent the Hamas, the PIJ (Palestine Islamic Jihad) and others smuggling weapons and other contraband into Gaza through a remarkable network of underground tunnels.  The corridor assumed great significance after Israel's withdrawal from the Sinai Peninsula in 1982 and later after its disengagement from Gaza in 2005; it has long been among the more contested spaces in the Middle East.  According to the IDF, the term “Philadelphi Corridor” was allocated during a routine military planning conference and the choice was wholly arbitrarily with no historical or geographical significance related to the region or any individual.

Just because a military say a code-name has no particular meaning doesn’t mean that’s true; the IDF is no different to any military.  The most obvious possible inspiration for the “Philadelphi corridor” was the Egyptian pharaoh Ptolemy II Philadelphus but one influence may have been cartographic, the geographic shapes of the Gaza Strip (left) and the US city of Philadelphia, Pennsylvania (right) quite similar and were the monstrosities Northwest, West & Southwest Philadelphia to be annexed by adjacent counties, the shapes of the two would be closer still.  

Lindsay Lohan in Philadelphia, 2012.

The Philadelphi corridor has assumed a new importance because Benjamin Netanyahu (b 1949; Israeli prime minister 1996-1999, 2009-2021 and since 2022) has added Israeli control of it to his list of pre-conditions for any ceasefire in negotiations between his government and the Hamas.  It was designated as a demilitarised border zone after the withdrawal of Israeli settlements and troops from Gaza in 2005, prior to which, under the terms of Israel’s Camp David peace treaty with Egypt (1979), the IDF had been allowed to maintain limited troop formations in corridor but without heavy weapons or heavy armour.  Old Ariel Sharon (1928–2014; prime minister of Israel 2001-2006) arranged the Israeli withdrawal from Gaza subsequently forming the Kadima (Forward) political party because he could persuade the Likud (The Consolidation) party to follow his vision.  Very much a personal vehicle for Mr Sharon, Kadima did not survive his incapacitation from a stroke while the Likud fell into the hands of Mr Netanyahu.  Following the Israeli withdrawal, responsibility for the corridor’s security fell to Egypt and the Palestinian Authority, this maintained until the Hamas took control of Gaza in 2007; it was seized by Israel in May 2024 as the IDF’s Gaza ground offensive extended into Rafah.

Over the years, the tunnel complex has proved a remarkably effective means by which to facilitate cross-border smuggling of weapons, other materiel, fuel and a variety of stuff including food, medicine and consumer goods, despite many attempts by the IDF and Egyptian authorities to end the traffic, the latter perhaps a little less fastidious in their endeavours.  The tunnels are impressive pieces of civil engineering, including electricity, ventilation systems, air-conditioning and communications facilities; some are sufficient large to allow heavy trucks to pass and there has long been speculation about the extent to which financial and logistical support for tunnel construction, maintenance & repair is channelled from the Gulf Arab states.  In Cairo, the government viewed the IDF’s seizure of the corridor with some alarm and remain a “status quo” power, insistent that an ongoing Israeli presence will “endanger” the Camp David peace treaty, no small matter because the “ripple effect” of the 1979 agreement had profound consequences in the region.

Still, Mr Netanyahu has made clear he intends to maintain a military presence in the corridor (including the Rafah crossing) and that remains an unnegotiable condition for a ceasefire with the Hamas; opposition to this stance has come from Cario, the Hamas and some of the third parties involved in the negotiation.  In Tel Aviv, that would not have been unexpected but there is now an increasingly persistent protest movement among Israeli citizens, the allegation being the prime-minister is cynically adding conditions he knows the Hamas will be compelled to reject because as long as the war continues, he can remain in office and avoid having to face the courts to answer some troubling accusations pre-dating the conflict.  Mr Netanyahu responded to this criticism by saying as long as the Hamas remained a threat (later refined to “as long as Hamas remained in control of Gaza”), the offensive needed to continue.  One of the great survivors of Middle East politics, Mr Netanyahu recently assured the more extreme of his coalition partners (described as “right-wing” which, historically, is misleading but descriptive in the internal logic of Israeli politics) by engineering a vote in cabinet binding Israel to retaining control of the corridor.  Despite this, opposition within the cabinet to the ongoing “moving of the goalposts” to prevent any possibility of a ceasefire is said to be growing.  The opposition accused the prime-minister of being more concerned with placating the extremists in his government than securing the release of the remaining hostages seized by the Hamas in the 7 October 2023 attack and left unstated but understood by implication was the message Mr Netanyahu regards them as the “collateral damage” in his manoeuvres to avoid the courts.

1350–1400: From the Middle English loupe & loup (loop of cloth; loophole; noose), from the earlier lowp-knot (loop-knot), of North Germanic origin, from the Old Norse hlaup (a run), used in the sense of “a running knot”, from hlaupa (to leap), ultimately from the Proto-Germanic hlaupaną (to leap, run) (and related to the Swedish löp-knut (loop-knot), the Danish løb-knude (a running knot) and the Danish løb (a course)..Etymologists are divided over whether loop has any connection with the Middle Irish & Old Irish lúb (bend, fold, loop) and perhaps akin to “leap”; nor is it clear if there was any relationship with the Middle Dutch lūpen (lie in wait, peep, peer).  The special use in metalworking dates from 1665-1675 and was etymologically unrelated; it was from the French loupe, a special use of loupe (wen, knob, gnarl), ultimately from a Germanic source.  The verb was derived from the noun.  Loop & looping are nouns & verbs, looper is a noun, looped is a verb & adjective and loopable & loopy are adjectives; the noun plural is loops.

Inner hippie: Lindsay Lohan likes the peace sign but in an age when high definition photography makes possible, even at a distance, the precise capturing of the arches, loops, and whorls of fingerprints, it’s now a potential risk.  AI (artificial intelligence) engines are now reported as achieving a success rate in excess of 50% in generating fake fingerprints so accurately they can “fool” biometric scanners.

As an acronym, LOOP can mean (1) loss of offsite power, (2) Listed on Other Page (online marketplaces), (3) Law of One Price (finance; economic theory) and Long-Range Open Ocean Patrol (admiralty jargon).  In dactylography (the study of fingerprints), the three primary shapes assumed by the ridges (arches, loops, and whorls) were first formerly defined in 1880.  It was first used of magnetic recording tape or film in 1931 while in computer programming in the sense of “a sequence of instructions, executed repeatedly”, the first known reference dates from 1947.  The noun looper (plural loopers) can mean (1) someone who loops (in various contexts, (2) an instrument or tool, such as a bodkin, for forming a loop in yarn or cord etc, (3) A moth having a caterpillar which arches its body into a loop in order to bring the back part of the body forward as it walks due to having fewer prolegs (an appendage of the abdomen of some insect larvae), (4) a (no almost always electronic) tool for creating music loops, (5) a golf caddy and (6) in baseball, a synonym of blooper (a fly ball that is weakly hit just over the infielders).  The adjective loopy can describe (1) something in such a shape or (2) (in slang) someone thought crazy or deranged.  The latter meaning dates from as late as 1923 but a century earlier it had entered English in the sense of “crafty or deceitful) in the novels of Sir Walter Scott (1771–1832).

There are literally dozens of derived “loop” phrases and idiomatic forms, some of the better known being: “infinite loop” (also as endless loop) (in computer programming a series of instructions which repeats until interrupted), “feedback loop” (a self-reinforcing or self-weakening effect which was used in the language of the military, political science, psychology, physics and other fields before becoming popular in discussions of global warming, “close the loop” (in managerial jargon, to follow up; to tie up loose ends; to resolve), “in the loop” (being well-informed; up to date; having current knowledge; being part of the discussion; the companion antonym being “out of the loop”, “fruitloop” (someone thought crazy or deranged (Fruit Loops originally a brand of sugary breakfast cereal), “death loop” (in video gaming the situation in which a player is killed and then respawns in the exact same time and place, destined thus endlessly to be killed, usually in a gruesome way, “belt loop” (the fittings on trousers & skirts through which one’s belt passes), “Lebanese loop” (in slang the “skimming device” fitted to an automatic teller machine (ATM or “cash dispenser”) used by criminals to collect personal information (such as pin numbers), “loophole” (in figurative use an ambiguity or exception in a rule or law that can be exploited in order to avoid the usual consequences (and originally "a slit in a castle wall used for observation or mounting a weapon)) and “loop quantum gravity” (a mysterious theory which attempts to reconcile quantum mechanics and general relativity, according to which space can be regarded as an extremely fine fabric of finite loops).

In the loop: MECCA MAXIMA, Bondi Junction, Sydney, Australia.

MECCA is an Australian cosmetics house with a presence in Australia, New Zealand, the UK and the PRC (People’s Republic of China), its private label brands including Mecca Cosmetica, Mecca Max, Kit and Mecca-ssentials.  It runs a programme (a kind of hybrid of a loyalty & reward scheme) called “Beauty Loop”, organized into layers, the parameters of which are based on one’s annual spend; as one spends more, one ascends to a higher level and, the higher one’s level, the greater the rewards (ie an effective discount).  The MECCA Beauty Loop has four levels of recognition (1, 2, 3 & 4) and purchases made online or in-store contribute to one’s annual total.  MECCA labels the customer profile in the Beauty Loop layers progressively as (1) Beauty Discoverer, (2) Beauty Devotee (3) Beauty Aficionado and (4) Beauty Connoisseur, explaining the Beauty Loop mechanics thus:

Beauty Loop is a popular scheme, said now to enjoy a membership in excess of 4½ million Beauty Discoverers, Devotees, Aficionados & Connoisseurs (MECCA doesn’t publish a breakdown) but in 2023 there was on-line speculation there may be an exclusive, secret layer of the loop (presumably known as Level 5) for those who spend much more.  It all sounded quite Masonic and there was speculation at least some MECCA staff must know about the mysterious Level 5 but were not permitted to discuss it and, if asked, were instructed to deny the existence of such a thing.  What Level 5 Beauty Loop members would be called attracted speculation and the most popular suggestions were “Beauty Addict”, “Beauty Obsessive” & “Beauty Cultist”, the consensus being floor staff would be able to confirm the identity of Level 5 members by some unobvious and ambiguous flag in the MECCA database rather than something Masonic like a secret handshake.  Fueling the conspiratorial atmospherics, MECCA seems to have adopted the Pentagon's "neither confirm nor deny" policy (invoked usually when questioned about the existence of nuclear weapons in certain places) so the hunt for a MECCA "deep throat" continues.

Thunk

Thunk (pronounced thunk)

(1) Onomatopoeic slang for sounds such as the impressive thud when the doors close on pre-modern Mercedes-Benz; representing the dull sound of the impact of a heavy object striking another and coming to an immediate standstill, with neither object being broken by the impact.

(2) In computer programming, a delayed computation (known also as a closure routine.

(3) In computing, in the Scheme programming language, a function or procedure taking no arguments.

(4) In computing, a specialized subroutine in operating systems where one software module is used to execute code in another or inject an additional calculation into another subroutine; a mapping of machine data from one system-specific form to another, usually for compatibility reasons, to allow a 16-bit program to run on a 32-bit operating system.

(5) In computing, to execute code by means of a thunk.

(6) As “get thunked” or “go thunk yourself”, an affectionate insult among the nerdiest of programmers.

(7) In colloquial use, a past tense form of think (the standard form being "thought").  Usually it's used humorously but, if erroneous, it's polite not to correct the mistake.

1876: The first documented instance as incorrect English is from 1876 but doubtlessly it had been used before and there’s speculation it may have be a dialectical form in one or more places before dying out.  There being no oral records and with nothing in writing prior to 1876, the history is unknown.  As an echoic of the sound of impact, it’s attested from 1952.  Although occasionally heard in jocular form, except in computing, thunk is non-standard English, used as a past tense or past participle of think.  The mistake is understandable given the existence of drink/drunk, sink/sunk etc so perhaps it’s a shame (like brung from bring) that it’s not a standard form except in computing.  The plural is thunks, the present participle thunking and the simple past and past participle thunked.  The numerical value of thunk in Chaldean Numerology is 4; the value in Pythagorean Numerology is 2.  Thunk & thunking are nouns & verbs, thunker is a noun and thunked is a verb; the noun plural is thunks.  The adjective thunkish is non-standard but is used in engineering and programming circles.

Getting thunked

The origin of the word to describe a number of variations of tricks in programming is contested, the earliest dating from 1961 as onomatopoeic abstractions of computer programming.  One holds a thunk is the (virtual) sound of data hitting the stack (some say hitting the accumulator).  Another suggestion is that it’s the sound of the expression being unfrozen at argument-evaluation time. The most inventive in that it was said to have been coined during an after-midnight programming session when it was realized a type of an argument in Algol 60 could be figured out in advance with a little compile-time thought, simplifying the evaluation machinery.  In other words, it had "already been thought of"; thus it was christened a "thunk", which is “the past tense of ‘think’ at two in the morning when most good programming is done on a diet of Coca-Cola and pizza”.

Door closing on 1967 Mercedes-Benz 230 S.  Until the 1990s, the quality of even the low-end Mercedes-Benz models was outstanding and the doors closed with a satisfying thunk.

Thunking as a programming concept does seem to have been invented in 1961 as “a chunk of code which provides an address”, a way of binding parameters to their formal definitions in procedure calls.  If a procedure is called with an expression in the place of a formal parameter, the compiler generates a thunk which computes the expression and leaves the address of the result in some standard location.  It usefulness was such it was soon generalised into: an expression, frozen with its environment for later evaluation if and when needed (that point being the closure), the process of unfreezing thunks called forcing.  As operating systems evolved into overlay-rich environments, the thunk became a vital stub-routine to load and jump to the correct overlay, Microsoft and IBM both defining the mapping of the 16-bit Intel environment with segment registers and 64K address limits whereas 32 & 64-bit systems had flat addressing and semi-real memory management.  Thunking permits multiple environments to run on the same computer and operating system and to achieve this, there’s the universal thunk, the generic thunk and the flat thunk, the fine distinctions of which only programmers get.  In another example of nerd humor, a person can be said to have their activities scheduled in a thunk-like manner, the idea being they need “frequently to be forced to completion”, especially if the task is boring.

Lindsay Lohan and her lawyer in court, Los Angeles, December 2011.

So it’s a bit nerdy but modern operating systems need thunking because 8, 16, 32 and 64-bit routines can need to run both concurrently and interactively on the same machine (real or virtual).  If a 32-bit application sends something with precision data types to a 64-bit handler, without thunking, the call will fail because the precise address can’t be resolved.  Although not literally true, it’s easiest to visualise thunking as a translation layer.

IBM OS/2 2.0 in shrink-wrap, 1992.

Thunking first entered consumer computing at scale with IBM’s OS/2 in 1987, an operating system still in surprisingly wide use and supported by IBM until early in the century.  Interestingly, although both OS/2 (and its successor eCom) have been unavailable for years, in August 2017, a private project released ArcaOS, an x86 operating system derived from OS/2 and, for personal use, it retails at US$129.00.  Like OS/2, it has some features which are truly unique such as, for the handful of souls on the planet who either need or wish simultaneously to run multiple 8, 16 and 32-bit text-mode sessions, (including those internally booting different operating systems in segregated memory) in their hundreds on the one physical machine.  First done in 1992 on OS/2 2.0, it’s still quite a trick and the on-line OS/2 Museum hosts an active community, development continuing.
