Tumblehome

Tumblehome (pronounced tuhm-buhl-hohm)

(1) In naval architecture, an inward and upward slope of the middle body of a vessel; of the sides of a ship: To incline or slope inwards, to contract above the point of extreme breadth.

(2) A conceptually similar shape applied, in reverse, to the upper body of an automobile.

1828: A compound word, tumble + home.  Tumble was from the Middle English tumblen (to fall over and over again, tumble), frequentative of the Middle English tumben (to fall, leap, dance), from the Old English tumbian, from the Proto-Germanic tūmōną (to turn, rotate).  It was cognate with the Middle Dutch tumelen and the Middle Low German tumelen & tummelen.  Home was from the Middle English home, hom, hoom & ham, from the Old English hām (village, hamlet, manor, estate, home, dwelling, house, region, country), from the Proto-West Germanic haim, from the Proto-Germanic haimaz (home, village), from the Proto-Indo-European tḱóymos (village, home), from the root tḱey-.  The (rare and probably extinct) alternative spelling is tumble home.  Tumblehome is a noun; the noun plural is tumblehomes.

The meaning of the word tumblehome has been well understood from its first appearance in the early nineteenth century but the origin has never been obvious.  Shipbuilders had for centuries been using variations of the design for a number of reasons but the first known instance of the word dates only from 1828 and then without explanation, suggesting the term may already have been in common use, at least within the industry.  An 1848 reference from a shipwright does however hint at some sense of novelty, noting “… the upper works usually incline towards the middle line, or as it is termed “tumble home”.  The word “tumble” to refer to the sides of ships appears to have been used at least as early as 1687 but the compound tumblehome seems not to have emerged for another hundred and fifty-odd years.  The idea always summoned was of the imagery of the sides of a ship “tumbling down” the slope created but why “home” was added remains a mystery, the assumption being it was based either on (1) an association with certain domestic architectural styles of the time (2) the romantic notion of the sea, to which the tumblehome falls, being "home" for sailors or  (3) the idea of a dilapidated house in the throes of "tumbling down", fallen bits an pieces accumulating at the bottom.

Big ships and fast cars

In automotive design (upper), the term is applied when the width of the cabin (cockpit or glasshouse) reduces as the height rises.  Although curved glass in the side windows of cars began widely to be adopted in the mid-1960s, thus creating a mild tumblehome effect, the term is applied only when it is sufficiently severe to be apparent to casual viewers.

In naval architecture (lower), the geometry is reversed, a tumblehome define as a hull which flares out as the sides approach the waterline.  Although in some vessels, the effect is barely detectable by the naked eye, it’s a technical term and applies to all hulls which dimensionally qualify.  The opposite, the classic shape for ships’ hull, is called the flare.

Tumblehome, unless taken to extremes, was functional in that it improved stability in warships under sail; sailing ships heel (they tend to lean over when moving) and tumblehome reduced this.  At the time, the biggest contributor to a warship’s mass on the upper decks was the guns and a tumblehome design, moving the centre of gravity lower, allowed armament to be maintained or even increased without further loss of stability.  Additionally, there was the benefit of making it harder for boarding parties to climb aboard.  In commercial shipping, vessels were long taxed on the basis of the square footage of a ship’s deck and fat ships with a pronounced tumble carrying the same freight but taxed less, were attractive.  Government fiscal policy thus influenced and distorted design and engineering principles in the same way tax arrangements of windows affected architecture and those on cylinder bores (adversely) affected engine design.

Lamborghini LP500 Countach prototype, 1971.

The Countach had one of the most extreme implementations, the angle meaning it was possible for only part of the side-window to be lowered but at least the Italians were more thoughtful than the Germans; in 1954, facing a similar challenge with the side-glass on the 300 SL (W198 1954-1957) gullwing, Mercedes-Benz simply fixed the panes, ventilation provided only by small quarterlights.  Neither flow-through ventilation or air-conditioning was available so driving in a gullwing could be hot and sticky experience and there's a reason they're sometimes seen being driven (at low speeds and not on public roads) with at least one door open. .  The tumblehome is used by high-performance cars because of the aerodynamic advantages it confers, reducing frontal area an allowing the curve of the greenhouse to be optimized for air-flow, lowering resistance.  Because of great advances made during the late twentieth century, refinements to tumblehomes no longer deliver the 3-5% improvements in a drag coefficient (CD) which once was possible, engineers now pursuing factional gains.  The origins in cars however lay in the quest for more interior space and for mass-market vehicles, bulging out the sides gained the odd vital inch and the technique, combined with curved side glass, has become almost universal although there has been the odd deviation.  Stylists are predicting tumblehomes are likely to become more exaggerated as sides need to be bulkier to meet more rigorous side-impact regulations and roof-lines are lowered slightly in the quest to reduce drag.

What professional hair stylists call “the tumblehome” is a triangulated shaping which is most cases can’t be achieved without an expert application of product and when sported by models on photo-shoots, it’s common for the angles and an illusion of volume to be achieved with engineering no more complex than a sheet of cardboard (cut to suit) being attached with hairclips to the back of the head.  The look can however be achieved with synthetics which can be persuaded sustainably to behave in a way human hair naturally resists and Lady Gaga (b 1986) made a tumblehome wig a signature feature of her “Fame Monster” period (2009-2010).  With natural hair, a tumblehome with hair a little shorter than that of Lady Gaga’s wig is sometimes technically achievable given the right hair and a generous use of product the sideways projection would be noticeably less.

The tumblehome style with the exaggerated elongations al la Gaga is rarely seen and usually represents a lot of work.  However, many take about as much effort to avoid the similar geometry of the “pyramid head”: a triangular shape with a flat crown area which flares to a wide bushy shape at the ends.  A function of length and weight for those with curly hair, pyramids happen usually when the strands are of almost uniform length and the curls tend to “stack”, the weight meaning the roots sit flattest on the scalp while towards the ends where the effective volume (hair + space) is greatest, the curled strands move sideways, unlike the behavior of straight hair which is purely downwards.

Stylists recommend layers as the best tactic to minimize the triangulation, the strategy essentially to create longer, diagonal layers to frame the face, meaning the remaining curls “sit into each other”.  What this does is simply physics, the layering on the surface reducing the weight, increasing the percentage of the volume on the crown area and although some are resistant, the best results will probably be achieved if the hair is cut dry because it will be presented at its natural weight.  When wet, the moisture content will disguise the extent of the left-right movement and exaggerate the up-down.  The shorter the layers of course the more effective the amelioration but this can be too radical for some so clients need to be turned into realists.

Cockade

Cockade (pronounced ko-keyd)

(1) A rosette, knot of ribbon, etc, worn usually on the hat as part of a uniform, as a badge of office, or the like.

(2) A feather or ribbon worn on military headwear, the colors of which served as unit identification.

(3) In (mostly military) aviation, an emblem of concentric circles of different colours, identifying the country to which an aircraft belongs (often called a roundel).

1650–1660: As cockade, an eighteenth century adaption of the earlier cockard, from the French cocarde (a knot of ribbons), from the Middle French cocquard (boastful, silly, cocky), the construct being coc (rooster, cock) + -arde (-ard).  The French suffix –arde was the female equivalent of –ard and was from the Middle French, from the Old French –ard & -art, from the Frankish -hard (hardy, bold), from the Proto-Germanic harduz (hard), from the primitive Indo-European kert- & kret- (strong).  It was used to form pejoratives, diminutives, and nouns representing or belonging to a particular class or sort.  The French cockade gained its name from the resemblance of the devices to a cock's crest, being from cocarde (feminine of cocard (arrogant, strutting) and thus cocquard (boastful, silly, cocky) which was an allusion to the behavior of the strutting rooster which appears so arrogantly boastful).  Cockade is a noun and cockaded is an adjective; the noun plural is cockades.

The companion (an now more widely used) term rosette describes a rose-shaped thing which may be an ornament, a fitting or any number of circular things, the best known of which are those with many small parts in concentric circles, especially when formed from a bunch or knot of ribbons and worn as a decoration or award.  Dating from 1790 from the French rosette (a diminutive of rose), rosette has a wider range of application than cockade and in the abstract is a generalized term referring to any number of stylized items which to one degree of another, are vaguely rose-like.  Rose was from the Middle English rose & roose, from the Old English rōse, from the Latin rosa, of uncertain origin but it may via Oscan be from the Ancient Greek ῥόδον (rhódon) (rose), from the Old Persian wṛda- (flower) and Middle Iranian borrowings including the Old Armenian վարդ (vard) (rose), the Aramaic וַרְדָּא‎ (wardā) & ܘܪܕܐ‎ (wardā), the Arabic وَرْدَة‎ (warda) and the Hebrew וֶרֶד‎ (wéreḏ)), from the primitive Indo-European wr̥dos (sweetbriar).  The –ette suffix was from the Middle English -ette, a borrowing from the Old French -ette, from the Latin -itta, the feminine form of -ittus.  It was used to form nouns meaning a smaller form of something.

Cockades fulfilled the function of maintaining the shape of a hat and were usually formed as a bow or knot of ribbons.  Inherently ornamental whetever their intended functional purpose, cockades quickly came to be used to signify the wearer’s identification with a political party, a particular military unit, or a household (in the form of livery).  They could be a matter of life or death during the French Revolution (1789) because the revolutionaries wore blue, white, and red cockades adopted from the colours of the royal family and the city of Paris.  The royalist forces and other reactionaries adopted white, orange, or black and yellow cockades (depending upon the nationality of the army in which they were serving), the French émigrés apparently preferring white.  The military often retained the colors but the use of cockades as such ceased for all but a handful of ceremonial uniforms when first armies and later navies ceased wearing cocked hats.  They’re still seen as a fashion item and a few of the surviving royal households have maintained their use in the leather cockades on the headgear of liveried coachmen and chauffeurs.

Although it seemed an early call, Nylon, after surveying the frocks at the 2023 Golden Globes, declared that rosettes were not only back but trending, noting the catwalks at the European spring shows were lush with floral themes.  Their conclusion: when roses bloom, rosettes surely follow.  If so, the fashion cycle is following the usual routine although the rapidity of cyclical churn does seem to have accelerated; whereas for most of the period since the seventeenth century when mass-produced rosettes first became a thing, the gaps between their splashes of popularity could be measured in decades, now they seem to be showing up every second generation.  Widely used in the 1980s (often as a bolt-on to the dreaded scrunchie), they re-appeared early in the new millennium and now Nylon says they’re back.

Still used around the world as (mostly amateur) awards in sporting and other competitions, rosettes displaying party affiliations were once a feature of elections in much of the English-speaking world but never really caught on in the US where badges, buttons, banner and latterly, stickers were preferred.  In the modern age, their use has faded just about everywhere except in the UK where they remain an essential part of atmospherics of campaigning and New Zealand where they’re still sometimes seen.  In the UK, they’re now more standardized than they were during much of the twentieth century when the sizes could vary greatly and there was no such thing as an official party color, some candidates even switching colors between polls, either at whim or in the quest for electoral advantage.  The advent of color television changed that and the party leaderships insisted on a consistent theme.  The electoral authorities also impose restrictions on the text which can be displayed and limit the size of rosettes which can be worn at polling places.  The convention of use in the UK evolved into:

Red: Labour
Blue: Conservative
Amber: Liberal Democrats
Green: Green Party
Yellow: Scottish National Party
Red, white and blue: Democratic Unionist Party
Green and orange: Plaid Cymru
Light blue: Reform UK
Purple: UK Independence Party

Nylon could be onto something.  The sequined lace column gown by Valentino Lindsay Lohan wore for the Falling for Christmas premiere (New York City, November 2022) was embroidered with a floral motif.  The reaction was generally positive.

Pre 900: From the Middle English oonly, onli, onlych, onelich & anely, from the Old English ānlich, ānlīc & ǣnlich (like; similar; equal; unique, solitary, literally "one-like”), from the Proto-Germanic ainalīkaz (one + -ly).  It was cognate with the Old Frisian einlik, the obsolete Dutch eenlijk, the German ähnlich (similar), the Old Norse álíkr, the Old High German einlih, the Danish einlig and the Swedish enlig (unified).  Synonyms include solitary & lone in one context and peerless & exclusive in the other.  Only is a noun, adjective, adverb & conjunction, onliness, onlyer & onlier are nouns and onliest & onlest are adjectives ; the noun plural is either onlys or onlies (both rarely used).

Only’s use as an adverb (alone, no other or others than; in but one manner; for but one purpose) and a conjunction (but, except) developed in Middle English.  In English, the familiar distinction of only and alone (now usually in reference to emotional states) is unusual; in many languages the same word serves for both although Modern German has the distinction in allein/einzig.  The mid fifteenth century phrase "only-begotten" is biblical, translating Latin unigenitus and Greek monogenes; the Old English word was ancenned. The term "only child" has been in use since at least the early eighteenth century.  The derived forms were once in more frequent use than now.  Someone who only adheres to the particular thing mentioned, excluding any alternatives. Onlyism (definitely non-standard) used to be quite a thing in Christianity in matters where there were different versions of documents and among Church of England congregations (often in the same parish) some were once adamant that only a certain edition of the Book of Common Prayer was acceptable and the others represented revisionism, heresy or, worse of all, smelled of popery.  Thus there were 1549-onlyiers, 1559-onlyiers, 1562-onlyiers etc.  The same factionalism of course continues to exist in many religions (and in secular movements and institutions too) but onlier has faded from use.  The adjectives onliest & onlest (a superlative form of only used almost exclusively in the US) are now rare and onlest is used mostly in African American Vernacular English (AAVE).  

The construct of the Old English ānlīc being ān (one) + -līc (-ly), only is thus understood in Modern English as on(e) + -ly.  One was from the Middle English oon, on, oan & an, from the Old English ān (one), from the Proto-West Germanic ain, from the Proto-Germanic ainaz (one), from the primitive Indo-European óynos (single, one).  It was cognate with the Scots ae, ane, wan & yin (one); the North Frisian ån (one), the Saterland Frisian aan (one), the West Frisian ien (one), the Dutch een & één (one), the German Low German een; the German ein & eins (one), the Swedish en (one), the Norwegian Nynorsk ein (one), the Icelandic einn (one), the Latin ūnus (one) & Old Latin oinos and the Russian оди́н (odín); doublet of Uno.

The –ly prefix was from the Middle English -ly, -li, -lik & -lich, from the Old English -līċ, from the Proto-West Germanic -līk, from the Proto-Germanic -līkaz (having the body or form of), from līką (body) (from whence Modern German gained lich); in form, it was probably influenced by the Old Norse -ligr (-ly) and was cognate with the Dutch -lijk, the German -lich and the Swedish -lig.  It was used (1) to form adjectives from nouns, the adjectives having the sense of "behaving like, having a likeness or having a nature typical of what is denoted by the noun" and (2) to form adjectives from nouns specifying time intervals, the adjectives having the sense of "occurring at such intervals".

The different phonological development of only and one was part of the evolution of English.  One was originally pronounced in the way which endures in only, atone and alone, a use which to this day persists in various dialectal forms (good 'un, young 'un, big 'un et al), the long standard pronunciation "wun" emerging around the fourteenth century in southwest and west England.  William Tyndale (circa 1494–1536), who grew up in Gloucester, used the spelling “won” in his translations of the Bible which were first published between 1525-1526 and the form slowly spread until it was more or less universal by the mid-eighteenth century.  The later use as indefinite pronoun was influenced by the unrelated French on and Latin homo.

The cardinals and bishops in England probably neither much noticed nor cared about Tyndale’s phonological choice but they certainly objected to his choice of words in translation (church became “congregation” and priest became “elder”) which appeared to threaten both the institution of the Church and the centrality to Christianity of the clerical hierarchy.  Tried for heresy in 1536, he was pronounced guilty and condemned to be burned at the stake although, for reasons not documented, he was, after a ceremonial defrocking, strangled until dead while tied to the stake, his corpse then burned.

Although a thing which pedants enjoy correcting, the placement of “only” as a modifier matters only if putting it one place or the other would hinder clarity; there’s never been an absolute grammatical rule and, as long as the meaning is clear, it’s probably better to adopt whatever is the usual conversational style.  Strictly speaking, although “We only fuck vegans” means an assertion of a life consisting of nothing else, most would understand it as a statement of one who is prepared to contemplate intimacy only with vegans.  The best compromise to adopt is probably that recommended for handling the split infinitive: Use the more exact “We fuck only vegans” in formal use such as in writing and the more natural, conversational “We only fuck vegans” otherwise.  Note that a sign held aloft at a protest, although obviously something “in writing” is not an example of formal use; it’s just part of the conversation.

No ambiguity: Lindsay Lohan in sweatshirt from the I Only Speak LiLohan range.

Care must be taken to avoid ambiguity, especially in writing because the intonations of speech and other visual clues are not there to assist in the conveying of meaning.  Were one to say “She only fucks vegans after midnight”, quite what is meant isn’t clear and the sentence is better rendered either as “she fucks only vegans after midnight" (ie carnivores need not apply) or “she fucks vegans only after midnight” (ie vegans must wait till the midnight hour).  In informal English, only is a common sentence connector but again, this should be avoided in formal writing where “only” should be placed directly before the word or words that it modifies.

Pistanthrophobia

Pistanthrophobia (pronounced piss-an-thruh-foh-bee-uh)

(1) The fear of trusting one's partner in a romantic relationship.

(2) A fear of trusting people because of dreadful past experiences.

1990s: A compound word, the construct being the Ancient Greek πίστις (pístis) (trust; faith in others; belief; truth), from the primitive Indo-European béydtis (equivalent to πείθω (peíthō) (I persuade) +‎ -τις (-tis) (the suffix added to verb stems to form abstract nouns or nouns of action, result or process)) + anthro- (a  (non-standard) alternative form of anthropo- (a combining form of the Ancient Greek ἄνθρωπος (ánthrōpos) (man, human being) +‎ -phobia (fear of a specific thing; hate, dislike, or repression of a specific thing) from the New Latin, from the Classical Latin, from the Ancient Greek -φοβία (-phobía); it was used to form nouns meaning fear of a specific thing (the idea of a hatred came later)).  Pistanthrophobia is a noun; the noun plural is pistanthrophobias.

Pistanthrophobia is one of the “phobias” which owes its existence to the internet and may even have pre-dated the world-wide-web because some archived bulletin boards (there were several devoted to phobias which is something of a hint about the nature of the obsessives who stalked the boards at 2400 baud) includes entries for the word although it difficult to work out quite when first it appeared.  With the arrival of social media, self-help pages flourished and, of course, few need as much help as pistanthrophobics.  Whether, prior to the internet, there were many fewer phobias as exist today isn’t known but since the 1990s many more have been described, some obviously for jocular effect and while some seem only to state the obvious (atomosophobia said to be the “fear of atomic explosions”) pistanthrophobia surely is a helpful addition because it must be a common condition.  It’s not however a medical diagnosis and has never appeared in any edition of the American Psychiatric Association's (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM), those who clinicians find to be pistanthrophobic handled with whatever is thought to be an appropriate diagnosis under the DSM’s five criteria for categorizing phobias: (1) animal type, (2) natural environment type, (3) blood-injection-injury type, (4) situational type & (5) other types.

Although originally applied to those who avoided romantic attachments because of a traumatic experience in a prior relationship, the term is also applied to those unable to trust others because of instances of rejection or betrayal.

Pistanthrophobia was first defined as the fear of being hurt by someone were one to enter into a romantic relationship and from the start the condition was thought something induced by a painful experience in a prior relationship.  The consequence of such traumas manifest as a fear of again suffering hurt and as an avoidance strategy, intimacy with others is avoided.  Like many phobias, the symptoms can vary in nature and extent but they may include (1) panic and fear, which can excessive, persistent, and wholly disproportional to the level of threat, (2) escape desires which typically manifest as a strong urge to get away from the triggering event or individual, (3) a shortness of breath (or hyper ventilation for those prone to panic attacks), (4) a racing heartbeat and (5) trembling and the onset of cold sweats.  Sufferers will change their patterns of behavior to the point of avoiding not only close contact but even casual conversations with anyone who might be a potential partner.  They will be seen to become guarded and socially withdrawn and at the very least, unresponsive to flirtation although it’s more likely they’ll become stressed and attempt to disengage from the interaction.  Flirtation is to a pisanthrophobe a threat and they become hyper-vigilant to the point where their heightened sensitivity will mean they misinterpret even benign conversations.  However, there are those who merely have no wish, for whatever reason, to enter into any romantic arrangements even when there’s been no preceding trauma and they are not pistanthrophobic.  The phobia is specific to the reactions and can exist even where there’s no history of trauma.

Vladimir Putin (b 1952; president or prime minister of Russia since 1999, centre) and Yevgeny Prigozhin (b 1961, noted multi-faceted Russian oligarch, left).

Mr Putin might find it hard again to trust others after his recent experience with Mr Prigozhin.  The president probably thinks he’s entitled to feel betrayed because Mr Prigozhin, as a billionaire oligarch and CEO of Mr Putin’s private army really was a thing of his creation and in sending a military convoy along the highway to threaten Moscow (a revolt, mutiny or insurrection depending on one’s interpretation), Mr Prigozhin was showing at least ingratitude.  Also not very trusting is likely to be Mr Prigozhin who may have little faith in the deal he agreed to: political exile in Russia’s neighboring vassal state of Belarus and an indemnity from prosecution in exchange for ending his quixotic revolt.  It’s certainly plausible he’ll avoid a Russian courtroom but his thoughts have probably turned to things such as accidents like falling from a tall building, being run over by several trucks, inadvertently ingesting poison or being exposed to a nerve agent like Novichok.  As Ernst Röhm (1887–1934; chief of the Nazi Sturmabteilung (the stormtroopers (the SA)) discovered in 1934, there can be consequences even for the things one hasn’t done but people think one might and as Mr Prigozhin probably impressed on Wagner’s troops more than once: “For everything you do there’s a price to be paid.”

Deadman

Deadman (pronounced ded-man or ded-muhn)

(1) In architecture and civil engineering a heavy plate, log, wall, or block buried in the ground that acts as an anchor for a retaining wall, sheet pile etc, usually by a tie connecting the two.

(2) A crutch-like prop, used temporarily to support a pole or mast during the erection process.

(3) In nautical use, an object fixed on shore temporarily to hold a mooring line.

(4) In nautical use, a rope for hauling the boom of a derrick inboard after discharge of a load of cargo.

(5) In mountaineering a metal plate with a wire loop attached for thrusting into firm snow to serve as a belay point, a smaller version being known as a deadboy.

(6) In slang, a bottle of alcoholic drink that has been consumed (ie is empty).

(7) In the operation of potentially dangerous machinery, a control or switch on a powered machine or vehicle that disengages a blade or clutch, applies the brake, shuts off the engine etc, when the driver or operator ceases to press a pedal, squeeze a throttle, etc; known also as the deadman throttle or the deadman control.  The hyphenated form dead-man is often used, both as noun and adjective.  Deadman is a noun and the noun plural is deadmans which seems ugly and a resulting formation such as "seven deadmans" is surely clumsy but most authoritative reference sources insist only "deadmans" will do.  Deadmen or dead-men is tolerated (by some liberal types) on the same basis as computer "mice" although "mouses" doesn't jar in the way "deadmans" seems to.

Circa 1895: A compound word, the construct being dead + man.  Dead was from the Middle English ded & deed, from Old English dēad, from the Proto-West Germanic daud, from daudaz.  The Old English dēad (a dead person; the dead collectively, those who have died) was the noun use of the adjective dead, the adverb (in a dead or dull manner, as if dead," also "entirely") attested from the late fourteenth century, again derived from the adjective.  The Proto-Germanic daudaz was the source also of the Old Saxon dod, the Danish død, the Swedish död, the Old Frisian dad, the Middle Dutch doot, the Dutch dood, the Old High German tot, the German tot, the Old Norse dauðr & the Gothic dauþs.  It's speculated the ultimate root was the primitive Indo-European dheu (to die).

Man was from the Middle English man, from the Old English mann (human being, person, man), from the Proto-West Germanic mann, from the Proto-Germanic mann (human being, man).  Doublet of Manu.  The specific sense of "adult male of the human race" (distinguished from a woman or boy) was known in the Old English by circa 1000.   Old English used wer and wif to distinguish the sexes, but wer began to disappear late in the thirteenth century, replaced by mann and increasingly man.  Man also was in Old English as an indefinite pronoun (one, people, they) and used generically for "the human race, mankind" by circa 1200.  Although often thought a modern adoption, use as a word of familiar address, originally often implying impatience is attested as early as circa 1400, hence probably its use as an interjection of surprise or emphasis since Middle English.  It became especially popular from the early twentieth century.

Calameo Dual-purpose MIL-SIM-FX mechanical dead-man and detonator switch (part-number MIL-12G-DMS).

The source of the name is the idea that if something is likely to in some way be dangerous if uncontrolled, operation is possible only if some device is maintained in a state which is possible only by a person not dead or in some debilitated condition.  The classic example is the train driver; if the driver does not maintain the switch in the closed position, the train slows to a halt.  Some manufactures describe the whole assembly as a "deadman's brake" and the part which is subject to human pressure as "deadman's switch" (or deadman's handle".  The phrase "dead man's fingers" is unrelated and is used variously in zoology, botany and in cooking and "dead man's rope" is a kind of seaweed (a synonym of sea-laces).  The legend of the "dead man's hand" (various combinations of aces and eights in poker) is based on the cards in the hand held by the unfortunate "Wild Bill" Hickok (1837–1876) when shot dead at the poker table.  A "dead man's arm" was a traditional English pudding, steamed and served in the cut-off sleeve of a man's shirt.  The phrase "dead man walking" began as US prison slang to refer to those on death row awaiting execution and it's since been adopted to describe figures like politicians, coaches, CEOs and the like who are thought about to be sacked.  Reflecting progress in other areas, dictionaries now list both "dead woman walking" and "dead person walking" but there scant evidence of use.

Deadman and the maintenance of MAD

The concept of nuclear deterrence depends on the idea of mutually assured destruction (MAD): that there would be certain retaliation, even if a nuclear first-strike destroyed the usual command and control structures of an adversary, that would not guarantee there wouldn’t be a nuclear counter-strike.  All front-line nuclear-weapon states employ systems to ensure a residual capacity to retaliate, even after suffering a catastrophic first strike, the best known of which are the Russian Мертвая рука (Dead Hand) and the US AN/DRC-8 (Emergency Rocket Communications System), both of which are often referred to as doomsday devices.  Both exist to close the strategic nuclear strike control loop and were inventions of the high Cold War, the USSR’s system later taken over by the successor Russian state.  The metaphor of a deadman is accurate to the extent of the need to keep closed a loop, the difference being the consequences.

The most extreme scenario is one in which there is left not a living soul with access to the loop.  In this case, the system switches from one designed to instigate a launch of ballistic missiles to one where some act is required to prevent the attack and is thus dubbed fail-deadly, the reverse of the fail-safe systems designed to prevent inadvertent launches.  The doomsday systems use a variety of mechanical and electronic monitoring protocols designed to (1) detect that a strike has occurred, (2) determine the extent of damage and (3) attempts to maintain or restore the usual communication channels of the military chain of command.  If the systems determine worst-case circumstances exist, a retaliatory launch of intercontinental ballistic missiles (ICBMs) will be triggered.  Neither the Kremlin nor the Pentagon tend to comment on such things but, over the years, there have been (what are assumed to be managed) leaks that the systems are usually inactive and activated only during times of crisis but the veracity of this is unknown.

One obvious theoretical vulnerability in the USSR’s and US systems is that at points it is electronic and therefore reliant on hardware, software and an energy source.  The UK government has an entirely analogue system which uses only pen and paper.  Known as letters of last resort, each incoming prime minister writes, in their own hand, four identical letters which are placed in a sealed envelope, given to the captain of each of the navy’s ballistic missile submarines who keeps it in his on-board safe.  The letters are only to be opened if an enemy (presumably nuclear) strike has damaged the chain of command to the extent it is no longer possible for the civilian government to instruct the military on what retaliatory action to take.  As soon as a prime-minister leaves office, the letters are, unopened, destroyed and replaced with ones from the new premier.  Those circumstances requiring a letter to be opened have never transpired and no prime-minister has ever commented publicly on what they wrote so the contents remain a genuine secret, known only to the writer and whomever they told.  So, although the only people who know the contents have never spoken, the consensus has long been the captains are likely to be given one of four options: 

(1) Retaliate.  Each of the four submarines is armed with up to sixteen 16 Trident II SLMBs (submarine-launched ballistic missiles), each missile equipped with up to twelve independently targeted warheads with a range of 7,000 miles (11,000 km).  There is always at least one at sea and the Admiralty never comments on its location although, in times of heightened political tension, additional boats may be activated.

(2) Not retaliate.

(3) The captains should use their judgment.  This, known as “the man on the ground” doctrine has a long tradition in the military although it was in some circumstances rendered redundant by advances in real-time communications.  In this case, it’s “the man under the water”.  An interesting question which touches on constitutional, international and military law, is the question of the point at which a state ceases to exist and the orders of a regime can be no longer said legally to be valid.

(4) Proceed to a place under an allied country's command or control.

Friedrich Wilhelm Nietzsche (1844-1900).

There is also a probably unexplored fifth option: a prime-minister could leave in the envelope a blank page.  This presumably would be substantively the same as option (3) but would denote a different political message to be mulled over in whatever remained of civilization.  No prime-minister has ever commented publicly on the thoughts which crossed their minds when writing these notes but perhaps some might have recalled Nietzche’s words in Beyond Good and Evil: Prelude to a Philosophy of the Future (1886): "He who fights with monsters might take care lest he thereby become a monster.  And if you gaze for long into an abyss, the abyss gazes also into you."  Although troubled when he wrote that, he wasn't yet quite mad.

Sanpaku

Sanpaku (pronounced san-pach-ew)

The presence of visible white space (sclera) above or below the iris of the human eye.

Pre 1800s: A borrowing from the Japanese 三白 (sanpaku) (three whites) or 三白眼 (sanpaku gan) (three-white eyes).  Sanpaku is a noun and sanpakuish is an adjective; the noun plural is sanpakus.

Sanpaku (三白) (three whites) & Sanpaku gan (三白眼) (three-white eyes) are Japanese terms from traditional Chinese & Japanese medicine and they describe the “condition” in which the white of the eye is visible either above or below the iris when looking straight ahead.  Although the word was popularized by Japanese educator and nutritionist Nyoichi “George” Ohsawa (1893–1966) when he published the book You Are All Sanpaku in 1965, the idea had existed in Oriental medicine probably for centuries although it’s impossible accurately to determine its origin.  It was mentioned in the diaries of at least one nineteenth century US Navy physician but attracted no interest in the West until the release of hsawa san’s book.  In Western medicine the phenomenon is described as “lower scleral show” or “inferior scleral show”, terms which are merely descriptive because (1) it’s something thought within the range of normality, (2) in indicative of no other mental or physical states and thus (3) is not considered a medical condition requiring treatment, the state either genetic or induced by aging, trauma or clinical and aesthetic dermatology procedures.  In short, the medicalization of sanpaku is thought a superstition thus, predictably, on social media ,“sanpaku eyes” seems to have a cult following.

In You Are All Sanpaku, Ohsawa san described Sanpaku as a condition which indicated physical and mental imbalances and discussed its significance in relation to diet and overall well-being.  Historically, sanpaku is believed to have entered oriental medicine from the Japanese practice of “face-reading” and those with eyes observed thus were considered ill-fated and destined for a life filled with misfortune, culminating often with an early demise.  It gained a following on social media by the usual means: celebrity association.  Diana, Princess of Wales, President John Kennedy & Marilyn Munroe, all of whom died young, were all sanpakus and as Ohsawa san warned in You Are All Sanpaku: the eyes indicate someone's fate, signifying imminent danger or an “early and tragic end.”

Early and tragic ends: John Kennedy (JFK, 1917–1963, left), Diana, Princess of Wales (1961-1997, centre) and Marilyn Monroe (1926–1962, right)

The original basis of “face reading” isn’t known but as a diagnostic tool it focused on the matter of “balance”, something important also to the physicians of Antiquity who identified the “four humors”: flegmat (phlegm), sanguin (blood), coleric (yellow bile) & melanc (black bile) which were the causative against of the four personality types, the phlegmatic, the sanguine, the choleric & the melancholic.  In the East, signs of sanpaku meant a man’s whole system (physical, physiological and spiritual) was out of balance, something caused by sins committed against the order of the universe, accounting for his sickness, unhappiness or insanity.  Ohsawa san noted that in the West such folk had come to be called “accident prone” and they were the ones who should take note of the warning from sanpaku, nature’s tap on the shoulder.  A practical author of self-help texts, Ohsawa san recommended sanpaku eyes should be treated with a macrobiotic diet, focusing on brown rice and soybeans, something on which he had real expertise as the founder of the macrobiotic diet.

Interestingly, the beliefs about sanpaku are culturally variable although universally it’s held the condition determines one's fate.  In the Japanese tradition those consequences are ill fate and misfortune while the Chinese associate sanpaku with good luck and wealth and this divergence has interested cultural anthropologists who study the symbolism and mythologies of different societies.  The tradition divides the eyes into yin sanpaku and yang sanpaku, the roots of this the ancient Chinese concept of yin and yang, representing the duality of opposing yet complementary forces in the universe.  Yin and Yang are fundamental concepts in Chinese philosophy and represent complementary and interconnected aspects of the universe. Yin is associated with qualities such as darkness, femininity, passivity, and coldness, while Yang is associated with light, masculinity, activity, and warmth. They’re seen as opposing forces that are in a constant state of dynamic balance and they exist within all phenomena, including human physiology, nature and society.  In this they differ from the (wholly un-related) concept in particle physics of matter and anti-matter.  Matter is the familiar stuff which is much of the physical universe (particles such as protons, neutrons, and electrons) while anti-matter consists of particles with the same mass as their matter counterparts but carrying an opposite charges.  When matter and anti-matter particles come into contact, they can annihilate each other, releasing energy.  Ying and Yang, mutually dependent, live in peaceful co-existence.

In Japanese face reading, yang sanpaku eyes (white part visible above the iris) reveal a person's dark and sinister nature, the eyes indicating the unstable mental state suffered by individuals exhibiting uncontrollable aggression, such as psychopathic murderers or serial killers.  Yin Sanpaku Eyes (white part visible below the iris) signify a different physical or mental imbalance, one caused by the abuse of drugs, alcohol, and sugar which disrupt the body's equilibrium.  Sanpaku eyes are far from rare, half of the population estimated to have sanpaku eyes, with at least 0.25-millimeter space between the iris and the upper and lower eyelids while some 20% show a separation with 1 millimeter or more.  However, the more celebrated of the species, those with a gap of 2 millimeters or more are fewer than 1% of the total.  Although discouraged by all in the profession except the odd, entrepreneurial cosmetic surgeon, treatment options are available to “correct” scleral show and the most effect treatment is aesthetic plastic surgery, specifically the procedure called blepharoplasty, which can correct the appearance of the eyes.  The construct of blepharoplasty was blepharo- +‎ -plasty.  Blepharo- was from the New Latin, from the Ancient Greek βλέφαρον (blépharon) (eyelid; a feature resembling an eyelid) and -plasty was from the Ancient Greek πλαστός (plastós) (molded, formed) which now has the special meaning in medicine meaning "repair, restoration or re-shaping of part of the body with a surgical procedure".

The Mean Girls demonstrate the range:  Rachel McAdams (b 1978, far left) & Lindsay Lohan (b 1986, centre-left) are in the half of the population who are either not sanpakus or the effect is imperceptible.  Lacey Chabert (b 1982, centre-right) is in the 20% of the population with a separation around 1mm while Amanda Seyfried (b 1985, far right) is a one-percenter who displays up to 2mm depending on her expression.

That humans even have white scleras has interested linguistic anthropologists, evolutionary biologists and other researchers and some have offered the Cooperative Eye Hypothesis which suggest the distinctive appearance evolved as a mechanism with which to enhance non-verbal communication.  According to this hypothesis, the high visibility of the iris & pupil against the white background allows an interlocutor more easily to track eye movements, helping individuals to understand where others are looking during interactions.  Observational studies revealed the way humans and other great apes move their heads and eyes in different ways, humans relying more on eye movements than head movements to see where someone else is looking.  Apes, without the white component in their eyes, tend more to move the whole head.  Not all support the cooperative eye hypothesis but it’s an interesting approach to understanding the evolutionary significance of the human eye's appearance and the sophistication of communication is certainly a noted difference between humans and apes.
