Gundeck

Gundeck (pronounced guhn-dek)

(1) Historically, on warships of the sail era, any deck (other than the weather deck) having cannons in permanent place from end to end.

(2) As gundecking, navy slang for falsifying records (now used also in merchant and other commercial shipping) and a synonym of “pencil whip” (to falsify records to convey the impression tasks have been completed).

1670–1680: The construct was gun + deck. Gun (in this context) was from the mid-fourteenth century Middle English gunne & gonne (an engine of war that throws rocks, arrows or other missiles from a tube by the force of explosive powder or other substance), from the “Lady Gunilda”, a very big crossbow with a powerful shot, the second element of the term from the Old Norse.  Originally restricted to the largest of projectile-launchers, “gun” was later applied to all firearms, pistols beginning to be described thus from circa 1745 although the military resisted the spread, preferring to restrict “gun” to mounted cannons, especially the big, long-barrelled (almost always big-bore) devices used with high velocity and long trajectory shells.  Hence the phrase “great guns” (used by both the army & navy) which were distinguished from small arms (muskets, pistols, rifles) and most western militaries still insist pistols are “side arms” rather than guns.  The idiomatic uses seem all to be modern: The use to describe a “thief or rascal: dates from 1858, the phrase “jumping the gun” was US English from 1812 which referenced a sporting competitor anticipating the starter’s pistol and “guns” to mean “a woman’s breasts” is said to be from as recently as 2006, the coining presumably because it was felt there weren’t a sufficient number of slang terms to use in anatomical tribute.  The origin of “son of a gun” is contested.  One theory suggests it dates from the eighteenth century when women sometimes accompanied sailors on long voyages, giving (as seems inevitable) birth on board, the most convenient place being the space between the cannons on the gundeck.  Such a child would therefore be called a “son of a gun” although this doesn’t account for the girls, the explanation for that perhaps as simple as “daughter of a gun” not so effortlessly rolling of the tongue.  There is no documentary evidence to support this and most etymologists appear to suggest the phrase was merely a euphemism for the vulgar “son of a bitch”.  Best of all however was the US Civil War (1861-1865) era story which in which “son of a gun” was used to explain a young lady’s otherwise inexplicable pregnancy by claiming a fired musket ball had passed through a man’s testicle before lodging in her ovaries.  There has never been any medical support for the theory but it’s not impossible the explanation was accepted (if not actually believed), south of the Mason-Dixon Line.

The construct of the name Gunnhildr (of which there are many variations) was the Old Norse gunnr (battle, war), from the primitive Indo-European gwhen- (to strike, kill) + hildr (battle), which technically creates a pleonasm but the duplication may be related to the wish to emphasise the size of the weapon.  The linguistic technique is noted in other languages such as that of the Darkinjung people (the original inhabitants of a part of costal New South Wales (NSW), Australia) in which the word for “water, pond etc” was woy and their name for a large body of water was woy woy (which endures as the name of the town Woy Woy, situated next to a deep tidal channel).  In a military context, the woman's name meant “battle maid”, some of the variations (Hilda, Gunilda, Gunhild, Gunhilda, Gunnhildr et al) familiar from Wagnerian interpretations.  Another Middle English adaptation of the women’s name Gunilda was gonnilde (cannon) and it appears also in a military stocktake (written in Anglo-Latin), a munitions inventory of Windsor Castle dating from 1330: “... una magna balista de cornu quae Domina Gunilda ...”  In the usual military manner, ancillary pieces picked up names associated with their primary device, hence the early fourteenth century gonnilde gnoste (spark or flame used to fire a cannon).  Something which might provide some insight into the (male) military mind is the frequency with which women’s names were used of the most extraordinarily powerful artillery pieces (Mons Meg, Big Bertha, Brown Bess et al).  The other influence on the development of the word may have been the Old French engon, a dialectal variant of engin (engine), the word engine’s original meaning better understood as something like “machine” or “constructed device”.

Deck (in this context) was from the mid-fifteenth century Middle English dekke (covering extending from side to side over part of a ship), from a nautical use of the Middle Dutch dec & decke (roof, covering), from the Middle Dutch decken, from the Old Dutch thecken, from the Proto-West Germanic þakkjan, from the Proto-Germanic þakjaną and related to the German Decke (covering, blanket) and the Proto-Germanic thakam (source also of the noun thatch), from the primitive Indo-European root steg & teg- (to cover).  It was thus a doublet of thatch and thack.  In English, the sense was soon extended by the Admiralty from “covering” to “platform of a ship” and the apparently mysterious use from the 1590s meaning “the pack of playing cards necessary to play a game” may have been an allusion to the cards being stacked like the decks of a big ship.  In audio engineering, the tape deck was first documented in 1949, apparently a reference to the flat surface of the old reel-to-reel tape recorders.  Dating from 1844, the deck chair gained its name from their well-publicized use on ocean liners.  The phrase “on deck” was an old admiralty term (famously “all hands on deck”) meaning “ready for action or duty” and by the 1740s it had entered general (non-nautical) use, in the US by 1867 entering the lexicon of baseball in the sense of “a batter waiting a turn at the plate”  The phrase “clear the desks” is now used in many contexts (and a favourite in corporate jargon) but originally was an instruction during a sea-battle to remove from the deck of a ship the wreckage of the engagement (downs masts, sails & spars, the dead and injured etc) which might interfere with a renewal of action.  Perhaps surprisingly, it’s documented only since 1852 but was likely to have been in use at sea for generations and it may be a variation of the French débarasser le pont. (clear the bridge).

Ships of the line

HMS Victory’s 32 Pounders on the Lower Gundeck.

Over time, warships evolved from two or three masted galleons into big, multi-decked affairs, the largest of which (those which would evolve into the dreadnoughts and the successor battleships of the twentieth century) were known as “ships of the line” which would form the backbone of the Western world’s great navies between the seventeen and nineteenth centuries before they gave way to the steam-power.  The idea of the “ship of the line” and the gundeck were intertwined because naval combat evolved into a fighting formation called the “line of battle” in which the opposing fleets manoeuvred to form lines so the guns could be fired in broadside (a simultaneous discharge of all the guns arrayed on one side of a ship).  Physics dictated the advantage in battle lay with the biggest ships with the biggest guns, thus the appearance of ships of the line with two, three or even four gundecks.  Of course, as decks with heavy guns were added, the centre of gravity rose and the need to find the optimal compromise balancing speed, stability and firepower preoccupied naval architects.

Model of HMS Royal William (1719), built as a First Rate (100 gun) triple-gundecked ship of the line, it only ever saw active service as a second and third rate ship.

By the turn of the eighteenth century, the definitive shape of a ship of the line had emerged.  The galleons protruding aft superstructure had been abandoned and they could displace as much as 2000 tons and be 200 feet (60 m) in length with crews of 500-800 sailors.  The cannons were arrayed along the (typically) three gundecks, the 30-odd heaviest guns (32-48 lb) on the lower gundeck, a similar number of 20-24 pounders in the middle with 24-30 12 pounders on the upper, the allocation reflecting the naval architects’ concerns with weight distribution.  The Royal Navy, rated it ships of the line according to firepower, the categories being third rate (up to 70 guns), second rate (70-100 guns) & first rate (over 100 guns) but the admirals were also realists, Lord Nelson (1758-1805) reckoning that on shore, a 12-gun fort could hold its own against a 100 gun ship of the line, a lesson which had apparently been forgotten when in 1915 some pre-dreadnoughts were sent to bombard the fortifications on the Gallipoli Peninsular when an unsuccessful attempt was made to force the straits of the Dardanelles and take Constantinople.

Gundecking

The term “gundecking” was naval slang for the falsification of records (and a synonym of “pencil whip”).  The origin of the tem is speculative but the most plausible explanation is said to relate to midshipmen (the lowest rung of the navy’s commissioned ranks) on the gundeck performing their celestial navigation tasks which (three time a day), were used to determine a ship's position using the morning star sights, the noon sun line, and the evening star sights.  However, not all midshipmen were as diligent as their captain would have hoped and rather than completing the dreary business of computing from fresh observations, simply reckoned the position on the basis of the speed and direction earlier recorded by their more contentious shipmates.  In other words, they made an educated guess and wrote down what they thought the numbers should be.  The term gundecking is now used to indicate the falsification of documentation in order to avoid doing the work required and in commercial shipping, the word is heard in cases which come before the courts.  There are stringent regulations which restrict how ships may process their bilge water (a truly disgusting mix of oil, water and sewerage) and on cruise ships with thousands of passengers there’s a lot of it and it’s an expensive business, ships’ engineers required to maintain hourly records of the purification processes prior to discharge into the open sea.  Because it costs a fraction as much to falsify the records and simply discharge the untreated bilge, some are tempted to “gundeck” the books and just open the valves on what is known as a “magic pipe” which is a straight line from bilge to ocean.  Fines in the order or US$40 million have been imposed so the costs of gundecking can be high.

In 2015, a Superior Court judge in Los Angeles found Lindsay Lohan had been doing a bit of gundecking in recording as “community service” the hours spent working with the charity group Community Service Volunteers (CSV) during the time she was in London appearing in a West End production of David Mamet's (b 1947) Speed-the-Plow (1988).  Some of the hours claimed were absorbed lobbying the US insurance company Esurance to donate US$10,000 (£6,440) to the CSV although a statement issued by CSV confirmed Ms Lohan had volunteered on the organisation's “Positive Futures” project, which works with teenagers in Hackney, adding “She has built strong relationships with the young volunteers she has worked with on the scheme.”  The community service order dates from traffic offences in 2012 and the judge found some of her activities in London, including “meeting & greeting” fans didn’t qualify as “community service” and ordered the gundecked hours be annulled with a further 125 hours to be performed.

Valhalla

Valhalla (pronounced val-hal-uh or vahl-hah-luh)

(1) In Norse mythology, a dwelling in Asgard, the Norse heaven, the hall of Odin, reserved to receive the souls of those who fell in battle and others who died heroic deaths.

(2) In casual use, by extension from the classic meaning, an abode of the gods or afterlife in general.

1696: From the New Latin Vahalla, from the Old Norse Valhöll, the construct being val(r) (the slain in battle (and cognate with the Old English wæl)) + höll (hall).  The heavenly hall in which Odin receives the souls of heroes slain in battle appears often in Norse mythology and the word Vahalla was introduced into English in Archdeacon William Nicolson’s (1655–1727) English Historical Library (1696).  Valr (those slain in battle) was from the Proto-Germanic walaz (source also of Old English wæl (slaughter, bodies of the slain)) from the Old High German wal (battlefield, slaughter), from the primitive Indo-European root wele (to strike, wound (source also of Avestan vareta- (seized, prisoner), the Classical Latin veles (ghosts of the dead), the Old Irish fuil (blood) & the Welsh gwel (wound)). Höll (hall) is from the primitive Indo-European root kel- (to cover, conceal, save).  Nicolson’s work was long known only to scholars and it wasn’t until the word was re-introduced in the eighteenth centuries by antiquaries there was any revival of interest but it was the work of Richard Wagner (1813–1883) in the next century that popularised the Norse myths and, in some circles, made Valhalla a cult.  The familiar figurative sense has been used since 1845.  Vahalla was also spelled Valhall, Walhalla & Walhall; the plural is Valhallas (and not always with the initial capital).

Hermann Burghart's (1834-1901) design of Valhalla and the rainbow bridge for the staging of Das Rheingold, Bayreuth, 1878.

Valhalla is the great hall where the god Odin houses the dead whom he deems worthy of dwelling with him.  In the Old Norse poem Grímnismál (The Song of the Hooded One), the architecture of Valhalla is described as honouring military tradition, the roof of the “gold-bright” Valhalla made from the shields of fallen warriors with their spears its rafters.  Around the many feasting tables are chairs made from breastplates and the gates are guarded by wolves, eagles circling above but there are different depictions and there's no one view of where Valhalla was.  In some Old Norse literature, it’s said to be located in Asgard, the gods’ celestial fortress yet other texts suggest it was underground, one of the many places of the underworld.

The dead who reside in Valhalla, the einherjar (the ɛinˌherjɑz̠, (those who fight alone, literally "army of one")), live on as warriors, fighting among each-other and enjoying vivid adventures during the day.  Yet every evening, their wounds are healed, and, restored to full health, they feat on roasted wild boar (Saehrimnir (from the Old Norse Sæhrímnir of unknown origin)) and a mead from the udder of the goat Heidrun (from the Old Norse Heiðrun of unknown origin), all the while waited on by the same beautiful Valkyries who circled the battlefields on which they were slain.  But the einherjar are doomed because Odin has recruited only the bravest soldiers for he wants them for his army in his struggle against the wolf Fenrir during Ragnarok, a battled which Odin and the einherjar are fated to lose.

Robert Lepage's (b 1957) design of Valhalla for the staging of Das Rheingold, Met Opera, New York, 2010.

Like the mythology of Greek and Roman antiquity, it’s possibly some of what was passed down during the middle ages is just one variation of the original myth(s) and it’s only in the poetry of Icelandic historian Snorri Sturluson (1179–1241) that there’s a statement of the path of the fallen to Valhalla.  Snorri’s Prose Edda (circa 1220), a four-volume work drawn from many sources remains the most complete and extensive collection of the Norse mythology known still to exist but the author was also a lawyer and politician and scholars have noted he wrote long after the old Norse paganism had been replaced by Christianity; there’s the suspicion this may have been an influence in the way he synthesized strands from earlier traditions with Christian teaching.  Snorri said those who fell on the field of battle ascend to Valhalla, while those who die a less heroic death are consigned to hell, the underworld.  That does seem unfair (and probably bad public policy) and elsewhere in the Edda, he’s not above allowing the odd fudge, just as Roman Catholic theologians would invent limbo, their own medieval conjecture to tidy up the margins of God’s mysterious ways.  Snorri makes no attempt to justify his (actually quite blatant) contradictions and it’s thought what he wanted to achieve was a kind of lineal alignment between the pagan ways and the Christian, Valhalla and Hel the same diametric opposite as Heaven and Hell in Christian eschatology.  However, as many surviving fragments from earlier texts attest, the tidy, systematized paganism described by Snorri was not entirely that which had been practiced.

Deadline

Deadline (pronounced ded-lahyn)

(1) The time by which something must be finished or submitted; the latest time for finishing something.

(2) A line or limit that must not be passed; a time limit for any activity.

(3) Historically, a boundary around a military prison beyond which a prisoner could not venture without the risk of being shot by the guards.

(4) A guideline marked on a plate for a printing press, indicating the point beyond which text would not be printed (archaic).

(5) Historically, a fishing line that has not for some time moved (indicating it might not be a productive place to go fishing).

(6) In military use, to render an item non-mission-capable; to remove materiel from the active list (available to be tasked); to ground an aircraft etc.

1864: The construct was dead + line.  Dead was from the Middle English ded, from the Old English dead (having ceased to live (also “torpid, dull” and of water “still, standing, not flowing”), from the Proto-Germanic daudaz (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 & German tot, the Old Norse dauðr and the Gothic dauþs), a past-participle adjective based on dau-, which (though this is contested by etymologists) may be from the primitive Indo-European dheu- (to die).  Line (in this context) was from the Middle English line & lyne, from the Old English līne (line, cable, rope, hawser, series, row, rule, direction), from the Proto-West Germanic līnā, from the Proto-Germanic līnǭ (line, rope, flaxen cord, thread), from the Proto-Germanic līną (flax, linen), from the primitive Indo-European līno- (flax).  The development in Middle English was influenced by the Middle French ligne (line), from the Latin linea (linen thread, string, plumb-line (also “a mark, bound, limit, goal; line of descent”)).  The earliest sense in Middle English was “a cord used by builders for taking measurements” which by the late fourteenth century extended to “a thread-like mark” which led to the notion of “a track, course, direction; a straight line.  The sense of a “limit, boundary” dates from the 1590s add was applied to the geographical lines drawn to divide counties.  The mathematical sense of “length without breadth” (ie describing the line drawn between points (dimensionless places in space)) was formalized in the 1550s and in the 1580s the “equatorial line was used to describe the Earth’s equator."  Other languages including Dutch, Finnish, Italian & Polish picked up deadline from English in unaltered form while the word also entered use in many countries for use in specific industries (journalism, publishing, television, printing etc).  Deadline & deadliner are nouns; deadlining & deadlined are verbs and postdeadline is an adjective; the noun plural is deadlines.

In the oral tradition, a deadline (which probably should be recorded as “dead line”) was a fishing line which for some time after being cast, hadn’t moved, indicating it might not be a productive place to go fishing.  The source of the first formalised meaning (a line which must not be crossed) was a physical line, the defined perimeter boundary line of prisoner of war (PoW) caps during the US Civil War (1861-1865): Any prisoner going beyond the “deadline” was liable to being shot (and thus perhaps recorded as “SWATE” (shot while attempting to escape).  Despite the name, the Civil War records indicate the deadline was rarely marked-out as a physical, continuous line but was instead defined by markers such as trees, signposts or features of the physical environment.  However, the word appears not to have caught on in any sense until 1917 when it was used to describe the guideline on the bed of printing presses which delineated the point past which text would not print.  It seems that the word migrated from the print room to the news room because by 1920 it was used in journalism in the familiar modern sense of a time limit: Copy provided after a specified time would not appear in the printed edition because it has “missed the deadline”.  From this use emerged “postdeadline” (after the deadline has passed) which sometimes existed on a red stamp an editor would use when returning copy to a tardy journalist, “deadliner” (a journalist notorious for submitting copy only seconds before a deadline) and the “deadline fighter” (a journalist who habitually offered reasons why their postdeadline copy should be accepted for publication).  Writers often dread deadlines but there are those who become sufficiently successful to not be intimidated.  The English author Douglas Adams (1952–2001), famous for The Hitchhiker’s Guide to the Galaxy (1979-1992) wrote in the posthumously published collection The Salmon of Doubt: Hitchhiking the Galaxy One Last Time (2002): “I love deadlines. I love the whooshing noise they make as they go by”.  Few working journalists enjoy that luxury.  Other similar expressions include “zero hour”, “cut-off date” and the unimaginative “time limit”.  Deadline was unusual in that it was one of the few examples of the word “dead” being used as a word-forming element in its literal sense, another being “deadman”, a device used mostly in railways to ensure a train is graceful brought to a controlled stop in the event of the driver’s death on incapacitation.

The meaning shift in deadline was an example of an element of a word used originally in its literal sense (dead men SWATE) changing into something figurative.  Other examples of the figurative use of the element include “dead leg”, deadlock, dead loss, dead load, dead lift, dead ringer, dead heat and dead light.  The interesting term “dead letter” has several meanings.  In the New Testament it was used by the Apostle Paul in his second letter to the Corinthians (2 Corinthians 3:6) to contrast written, secular law with the new covenant of the spirit.  Paul’s argument was that legal statutes, without the Spirit, were powerless to bring about salvation and were therefore “dead letter” whereas the new covenant, based on the Spirit, brings life:  He has made us competent as ministers of a new covenant--not of the letter but of the Spirit; for the letter kills, but the Spirit gives life.” (2 Corinthians 3:6).  So, law devoid of the power of the Holy Spirit to interpret and apply it is a “dead letter” that can never be transformative, unlike the new covenant which is based on a living relationship with God through the Holy Spirit.

In a post office, a “dead letter” (which can be a “dead parcel”) is an item of mail which can neither be delivered to its intended recipient nor returned to the sender, usually because the addresses are incorrect or the recipient has moved without leaving a forwarding address.  Within postal systems, there is usually a “dead letter office” a special department dedicated to identifying and locating the sender or recipient.  If neither can be found and the item is unclaimed after a certain time (and in many systems there are deadlines), it may be opened and examined for any identifying information that could be used to identify either and if this proves unsuccessful, depending on its nature, the item may be destroyed or sent to public auction.  Beyond the Pauline and the postman, “dead letter” is a phrase which refers to (1) a law or regulation which nominally still exists but is no longer observed or enforced and (2) anything obsolescent or actually obsolete (floppy diskettes, fax machines et al).  In law, some examples are quite famous such as jurisdictions which retain the death penalty but never perform executions.  There have also been cases of attempting to use the “dead letter” law as an expression of public policy: In Australia, as late as 1997, the preferred position of the Tasmanian state government was that acts of homosexuality committed by men should remain unlawful and in the Criminal Code but that none would be prosecuted, the argument being it was important to maintain the expression of public disapproval of such things even if it was acknowledged criminal sanction was no longer appropriate.  There may have been a time when such an approach made political sense but even before 1997, that time had passed.  As is often the case, law reform was induced by generational change.

Ratio

Ratio (pronounced rey-shoh (U) or rey-shee-oh (non-U))

(1) The relation between two similar magnitudes with respect to the number of times the first contains the second.

(2) The proportional relation; rate.

(3) In finance, the relative value of gold and silver in a bimetallic currency system.

(4) In mathematics, a quotient of two numbers or quantities.

(5) In western legal systems, the slang for ratio decidendi, the substantive part(s) of the judgment.

(6) In the metrics of the internet, the number of comments to a post or other expression on social media relative to the number of likes (a high ratio assumed to suggests disagreement with the contents of the original post).

1630–1640: From the Latin ratiō (a doublet of ration and reason) (a reckoning, account, numbering, derivation, calculation) from the base of rērī (to judge, think).  The original meaning in English, dating from the 1630s (reason, rationale, calculation, reckoning, numbering, calculation, judgment) mirrored the Latin practice while the mathematical sense "relationship between two numbers" is attested from the 1650s.  The use in theological texts in the sense of "reason, rationale" was a tribute to the original meaning in Latin (a reckoning, account, numbering, derivation, calculation), hence also the idea of "a business affair; course, conduct, procedure".  From this also emerged (in a transferred sense and applying to mental action), the meaning "reason, reasoning, judgment, understanding, that faculty of the mind which forms the basis of computation and calculation" (the ultimate origin of this being rat-, the past-participle stem of reri (to reckon, calculate (and also "to think, judge, believe), from the primitive Indo-European root re- (to think, reason, count).  The Latin ratio often was used to represent or translate the Greek logos (computation, account, esteem, reason) in works of philosophy, though the range of senses in the two do not wholly overlap because ratio lacks the essential "speech, word, statement" meaning which exists in the logos.  The familiar modern meaning "corresponding relationship between things not precisely measurable" had become common by the early nineteenth century.

Ratio Decidendi and Obiter Dictum

The ratio decidendi is a phrase in legal Latin meaning "reason (or rationale) for the decision” and the professional oral & verbal shorthand is ratio.  It’s the ratio decidendi which justifies the judgment and expresses the legal principle(s) which determine the outcome.  The ratio decidendi either creates or is consistent with legal precedent and in the common law’s hierarchical system, lower courts are required to follow precedents established by higher courts.

Obiter dictum the complimentary legal Latin phrase meaning "by the way" and the legal slag is variously dicta or (more commonly) obiter.  The obiter is the collective term for other substantive material in the judgment but not part of the reasoning for the decision, the remarks or observations made by a judge that do not form a necessary part of the decision.  There exists an informal test called the Wambaugh Inversion to determine whether a judicial statement is ratio or obiter.  This involves asking whether the decision would have been different, had the statement been omitted.  If so, the statement is crucial and is ratio; if not, it is obiter.  The rarely used plural for ratio is rationes decidendi whereas, because of the rules of Latin, obiter is used almost always in the plural as obiter dicta.  The difference between the ratio and the dicta is a most useful distinction but would be more helpful if judges could be prevailed upon to make if clear which is which; even bullet-point summaries would be handy.  One suspects many judges think themselves fine stylists of the language, a view not always shared by their captive audience.

B2BR: The bitemporal to bizygomatic ratio

Lindsay Lohan's bitemporal to bizygomatic ratio (B2BR), calculated by pinkmirror.com.  Her admirable B2BR ratio of 1.07 contributed to her overall beauty score of 8.5 (out of 10), putting her in the "beautiful" category.  The above image is rendered in the 1:2 aspect ratio of the DL envelope, favored by architects because the result is thought pleasing to the eye.  

Architects and engineers use all sorts of ratios in their calculations, some to improve aesthetic appeal and some to optimize specific strength.  In internal combustion engines, ratios are commonly used (compression ratio, connecting rod-to-stroke ratio et al) and in building design, the "DL envelope ratio" (1:2) references the standard DL envelope (110 x 220 mm; 4⅓ x 8⅔") which, when applied in architecture, is considered to produce a shape pleasing to the eye, apparently because it closely corresponds with the natural field of human vision.  In the beauty business there are also ratios, used predictably to compartmentalize various aspects of women's appearance so their degree of attractiveness can be reduced to a number.  The site pinkmirror.com helpfully provides an interactive analysis page, one component of which is the bitemporal to bizygomatic ratio (B2BR), a measure used in facial anthropometry (the study of facial measurements and proportions) and cosmetic and restorative surgery.  The B2BR compares the distance between the two temporal bones (bitemporal distance) with the distance between the two zygomatic bones (bizygomatic distance) in the face.  Notionally, the B2BR is set at 1:1 (a baseline for calculation purposes rather than an ideal) and if bitemporal distance is greater than that of the bizygomatic, the ratio will be greater than 1, indicating a relatively narrow midface whereas if the bizygomatic distance is greater, the ratio will be less than 1, indicating a relatively wide midface.  In medicine the B2BR is used as an indicative diagnostic tool which can be helpful in assessing certain genetic conditions that affect facial structure and in cosmetic & restorative surgery its used as one of the measures of facial proportions when planning treatments.  Some advanced systems in cosmetic facial surgery no use CAD (computer assisted design) software and 3D printing (essentially "prototyping" the "new" face) and the B2BR is one of the critical metrics used in both.

Limelight

Limelight (produced lahym-lahyt)

(1) In the lighting systems of live theatre, prior to the use of electricity, a lighting unit for spotlighting the front of the stage, producing illumination by means of a flame of mixed gases directed at a cylinder of lime and having a special lens for concentrating the light in a strong beam.

(2) The light produced by such a unit (and subsequently by lights using other technology.

(3) In theatre slang (1) a lighting unit (also clipped to “limes”), especially a spotlight & (2) by extension, attention, notice, a starring or central role, present fame (source of the general use of the word).

(4) The center of public attention, interest, observation, or notoriety.

1826:  The construct was lime + light.  Lime (in this context) was from the Middle English lyme, lym & lime, from the Old English līm, from the Proto-Germanic līmaz, from the primitive Indo-European sley- (smooth; slick; sticky; slimy).  It was cognate with the Saterland Frisian Liem (glue), the Dutch lijm, the German Leim (glue), the Danish lim (from the Old Norse lím) and the Latin limus (mud).  In chemistry, the word described any inorganic material containing calcium (usually calcium oxide (quicklime) or calcium hydroxide (slaked lime).  In literary or poetic use, it was used of any gluey or adhesive substance, usually in the sense of “something which traps or captures someone” and sometimes as a synonym for birdlime.  It was used as a verb to mean (1) to apply to some surface a coasting of calcium hydroxide or calcium oxide (lime) & (2) to smear with birdlime or apply limewash.

Light (in this context) was from the Middle English light, liht, leoht, lighte, lyght, & lyghte, from the Old English lēoht, from the Proto-West Germanic leuht, from the Proto-Germanic leuhtą, from the primitive Indo-European lewktom, from the root lewk- (light).  It was cognate with the Scots licht (light), the West Frisian ljocht (light), the Dutch licht (light), the Low German licht (light) and the German Licht (light) and related also to the Swedish ljus (light), the Icelandic ljós (light), the Latin lūx (light), the Russian луч (luč) (beam of light), the Armenian լույս (luys) (light), the Ancient Greek λευκός (leukós) (white) and the Persian رُخش‎ (roxš).  The early uses (in this context) all were related to the electromagnetic radiation in the spectrum visible to the human eye (ie what we still commonly call “light”).  Typically, the human eye can detect radiation in a wavelength range around 400 to 750 nanometers and as scientific understanding evolved, the shorter and longer (ultraviolet light and infrared light) wavelengths, although not visible, were also labeled “light” because, as a matter of physics, they are on the spectrum and whether or not they were visible to the naked eye was not relevant.  “Light” in the sense of illumination was literal but the word was also productive in figurative and idiomatic generation (the “Enlightenment”; “leading light”; “negative light”; “throw a little light on the problem”; “bring to light”; “light the way” et al).  Limelight is a noun & verb, limelighting is a verb, limelighted & limelit are adjectives and limelighter is a noun; the noun plural is limelights.

Lime (chemical formula: CaO) is composed primarily of calcium oxides and hydroxides (typically calcium oxide and/or calcium hydroxide) and the origin of the word lies in its early use as building mortar (because of its qualities of sticking or adhering).  It was the interaction of lime with other substances which lent the concrete mixed in Ancient Rome (known to engineers as “Roman concrete”) unique properties that made it remarkably durable and long-lasting (though despite the legend, it was no more “sticky” that other concrete using the same quantity of lime).  A critical ingredient in Roman concrete was a type of volcanic ash called pozzolana (abundant in the environs of Rome) which was mixed with lime and small rocks or rubble to create a paste that could be molded into various shapes and sizes.  What created uniqueness was the chemical reaction between pozzolana and lime when the mix was exposed to water, this creating a mineral called calcium silicate hydrate, the source of Roman concrete’s durability and strength.  Unusually, it was able to harden underwater and for centuries resist the effects of saltwater (indeed such exposure triggered a kind of “self repair reaction), making it ideal for building structures like harbors and aqueducts and in a happy coincidence, the easy accessibility of pozzolana meant Roman concrete could be produced at a lower cost than other building materials.

The term “limelight dress” was coined to describe a garment designed to attract the eye, making the wearing the “centre of attention” in the manner of a stage performer in the limelight: Rita Ora (left), Ariel Winter (centre) and Lindsay Lohan (right) illustrate the motif.  It's become something less easy to achieve because of the emergence in the past two decades of the "nude dress" and it may be that a more modest cut, if well executed, might work better for clickbait purposes, just because of the novelty.  Of late, “limelight” has also been used in mainstream fashion to refer to dresses made with neon-like fabrics which resemble a color under a bright light.

In the limelight: In a marquisette dress, Marilyn Monroe (1926–1962) sang happy birthday Mr President to President John Kennedy (JFK, 1917–1963; US president 1961-1963) at a Democratic Party fundraiser at New York's Madison Square Garden on 19 May 1962, ten days before his actual birthday.  Within three months, she would be dead.

Limelight was the common name for the Drummond light (or calcium light), a lamp of then unprecedented luminosity created by the burning of calcium oxide (lime).  The process of creating light by burning lime augment by oxygen & hydrogen had been invented in the early 1920s and, generating an intense white light, it was developed in 1925 for use in mining and surveying by Scottish army engineer Captain Thomas Drummond (1797-1840) and soon adopted for lighthouses although it became famous from the use in live theatre where directional spot-lights were used to illuminate the principal actors on stage and although the technology has moved on, in theatre, film & television production, catwalks etc, “limelight” is still often used to describe both the physical lighting equipment and the effect produced.  In popular entertainment, limelight came into use in the UK in the mid-1830s and, cheap to produce and easily exported, were soon in use around the world, even the military finding them useful, the army to assist the targeting of artillery (an early example of applying technology to fire-control systems) and the navy found they were vastly more effective than any other spotlight.  Limelights remained in widespread use until replaced by electric devices in the late nineteenth century but in some far-flung outposts of the British Empire, they were still in use even after World War II (1939-1945).

From the idea of the character on stage being highlighted by the limelight came the figurative use of the phrase “in the limelight” (noted since 1877) to refer to anyone on whom attention is focused.  This begat the related phrases “steal the limelight”, “bask in the limelight” & “hog the limelight”, all from the world of theatre but later adopted as required just about anywhere (in sport, corporate life etc).  “In the limelight” tends to be used only positively; those who are the focus of attention for reasons such as being accused of committing crimes or some transgression which might lead to cancellation are usually said to be “in the glare”.

Like the other manufacturers, Chrysler had some history in the coining of fanciful names for colors dating from the psychedelic era of the late 1960s when the choices included Plum Crazy, In-Violet, Tor Red, Limelight, Sub Lime, Sassy Grass, Panther Pink, Moulin Rouge, Top Banana, Lemon Twist & Citron Yella.  Although it may be an industry myth, the story told is that Plum Crazy & In-Violet (lurid shades of purple) were late additions because the killjoy board refused to sign-off on Statutory Grape.  Plymouth called their lime green Limelight while Dodge used Sub Lime.  The lurid shades so associated with the era vanished from the color charts in the mid-1970s, not because of changing tastes but in response to environmental & public health legislation which banned the use of lead in automotive paints; without the additive, production of the bright colours was prohibitively expensive.  Advances in chemistry meant that by the twenty-first century brightness could be achieved without the addition of lead so Dodge revived psychedelia for a new generation although Sub Lime became Sublime.  There was still a price to be paid however, Sublime, Red Octane, Sinamon Stick and Go Mango all costing an additional US$395 while the less vivid shades listed at US$95.

Null

Null (pronounced nuhl)

(1) Without value, effect, consequence, or significance; being or amounting to nothing; nil; lacking; nonexistent; something with a value or measure of zero; of or relating to zero.

(2) In electronics, a point of minimum signal reception, as on a radio direction finder or other electronic meter.

(3) In law, as null and void, without legal force or effect; not valid.

(4) In computing, Null (or NULL), a special marker and keyword in SQL (Structured Query Language) indicating that something has no value.

(5) In computing, the null character, the zero-valued ASCII character (also designated by NUL), often used as a terminator, separator or filler; this symbol has no visual representation; as null pointer (sometimes written NULL, nil, or None), used in computer programming for an uninitialized, undefined, empty, or meaningless value; as Null string, the unique string of length zero (in computer science and formal language theory).

(6) In computing, the null device, a special computer file (/dev/null on Unix systems) that discards all data written to it.

(7) In communications, as null modem, a specially wired serial communications cable.

(8) In mathematics, a zero value in several branches of the discipline including null set, a set that is negligible in some sense; of or relating to a set having no members or to zero magnitude; also an older term for the empty set.

(9) In physics, a point in a field where the field quantity is zero; as null vectors or curves in the causal structure of a Lorentzian manifold such as a Minkowski space-time.

(10) In statistics, as null hypothesis, a concept in hypothesis testing; companion concept is the null result, the absence of a hypothesized effect in the outcome of a scientific experiment

(12) In genetics, as null allele, a nonfunctional allele (a variant of a gene) caused by a genetic mutation.

(13) In political history as Stunde Null (a German military planning term meaning "Hour Zero"), a term referring to midnight on 8 May 1945 in Germany marking the end of World War II in Europe and the birth a new Germany (an attempt to dissociate post-war Germany from the Nazis).  The period immediately following this time is the Nachkriegszeit (the time after the war).

(14) One of the beads in nulled work (an ornamental craft producing work resembling beads strung on a rod).

1555–1565: From the Middle French nul, from the Latin nūllus from the Proto-Italic ne-oino-los from Proto-Italic oinos (one).  Synchronically nūllus was from ne (not) + ūllus (any) and thus meaning literally "not any".  The earlier form nulla (circa 1500), from the Italian nulla, from the Latin nūlla, feminine of nūllus (no one) was ultimately from the primitive Indo-European ne, óynos & -lós.  Null is a noun, adjective & verb, nulled is a verb & adjective, nulling is a noun & verb, nullity, nullification & nullificationist are nous and nullify, nullified & nullifying are verbs; the common nouns plural are nulls and nullings.

Null Island.

Null Island is an imaginary island located at 0°N 0°E (thus “Null”, zero being one of null’s synonyms) in the South Atlantic Ocean, the point at which equator crosses the prime meridian.  It’s not clear when Null Island was first “discovered” but it delighted many when in 2011 it appeared on Natural Earth, a public domain map dataset created by volunteer cartographers and GIS (geographic information system) analysts.  A modest 1m2 "land mass" (actually a buoy) located at 0°N 0°E in the digital dataset, Null Island was intended to help analysts flag errors in geocoding.  Somewhat analogous with the DNS (Domain Name System) which maintains a relationship between IP (Internet Protocol) addresses (which with computer networks communicate) and the familiar website names (which real people use), geocoding is a process which converts a physical address (such as a street address) into geographic coordinates, the most familiar of which are latitude and longitude.  It permits address to appear on digital maps and enables location-based services and applications to be integrated and distributed, mapping, navigation & advertising services depending on the system.  Of late, a particularly helpful application of the service has been the tracking of the spread of diseases. 

IBM & Null

In 1981, IBM explained why, in file systems, null had to exist in every directory (now often called folders).  If null didn’t exist, IBM maintained, operating systems wouldn’t necessarily be able to determine which were empty.  Advances in operating systems over forty-odd years, mean that’s no longer a problem but with the technology available in 1981, some of it dating back decades, the issue was real.  IBM also published what turned out to be a prescient vision of what became the widely distributed file systems of the internet, spread across continents, running on disparate hardware and operating systems yet able still functionally and administratively to interact.  Modern programming languages still take advantage of the existence (or non-existence) of null.  Below is a Python script to both check if a directory is empty and also check for exceptional situations such as a directory not existing.

import os
def main():
    dirName = '/home/varun/temp';
    '''
        Check if a Directory is empty and also check exceptional situations.
    '''   
    if os.path.exists(dirName) and os.path.isdir(dirName):
        if not os.listdir(dirName):
            print("Directory is empty")
        else:   
            print("Directory is not empty")
    else:
        print("Given Directory don't exists")
    '''
        Check if a Directory is empty : Method 1
    '''   
    if len(os.listdir('/home/varun/temp') ) == 0:
        print("Directory is empty")
    else:   
        print("Directory is not empty")
    '''
        Check if a Directory is empty : Method 2
    '''   
    if not os.listdir('/home/varun/temp') :
        print("Directory is empty")
    else:   
        print("Directory is not empty")
    print ("****************")
if __name__ == '__main__':
    main()
Output:
Directory is empty
Directory is empty
Directory is empty



In the commercial art business, if no frame is chosen, the order is tagged "Null Frame".

In computer programming, the "null frame" is a data packet containing no useful information and existing usually for the purposes of (1) maintaining an open comms channel or (2) as a marker for an end of transmission.  Null Frames are often used in conjunction with “heartbeat” (or “keepalive”) markers which provide a visual symbol indicating a connection remains active.  However, because null frames can be of variable size, they’re of use also as markers of the addressable space available in memory or buffers.  While there are other ways of doing this, null frames provide information about resource availability while themselves consuming almost no resources.  In the commercial art business, the expression “null frame” is used to indicate the customer has specified the product be supplied unframed.

Horology

Horology (pronounced haw-rol-uh-jee)

(1) The science of time.

(2) The art and science of making timepieces or measuring time.

(3) In Orthodox Christianity, the office-book of the Greek Church for the canonical hours.

1852: The construct was the Ancient Greek hōro (combining form of hra (hour; part of the day; any period of time)) + -logy.  The suffix -ology was formed from -o- (as an interconsonantal vowel) +‎ -logy.  The origin in English of the -logy suffix lies with loanwords from the Ancient Greek, usually via Latin and French, where the suffix (-λογία) is an integral part of the word loaned (eg astrology from astrologia) since the sixteenth century.  French picked up -logie from the Latin -logia, from the Ancient Greek -λογία (-logía).  Within Greek, the suffix is an -ία (-ía) abstract from λόγος (lógos) (account, explanation, narrative), and that a verbal noun from λέγω (légō) (I say, speak, converse, tell a story).  In English the suffix became extraordinarily productive, used notably to form names of sciences or disciplines of study, analogous to the names traditionally borrowed from the Latin (eg astrology from astrologia; geology from geologia) and by the late eighteenth century, the practice (despite the disapproval of the pedants) extended to terms with no connection to Greek or Latin such as those building on French or German bases (eg insectology (1766) after the French insectologie; terminology (1801) after the German Terminologie).  Within a few decades of the intrusion of modern languages, combinations emerged using English terms (eg undergroundology (1820); hatology (1837)).  In this evolution, the development may be though similar to the latter-day proliferation of “-isms” (fascism; feminism et al).  Descents of the Greek hōro came into use in many languages including the Hebrew הוֹרָה (hóra), the Romanian horă and the Turkish while from the Modern Greek χορό (choró) (accusative of χορός (khorós) (dance)) came Hora, a circle dance popular in the Balkans and Israel. In Late Latin, the derived form was horologium.

Between the early sixteen and nineteenth centuries the meaning was restricted to describing clocks or their dials by at least 1820 reference books were noting “term horology is at present more particularly confined to the principles upon which the art of making clocks and watches is established”.  The earlier sense in English reflected the inheritance from the Latin horologium (instrument for telling the hour (and in Medieval Latin “a clock”), from the Ancient Greek hōrologion (instrument for telling the hour (ie the sundial; water-clock et al), from hōrologos (telling the hour).  Horological was used as early as 1590s, horologiography (the art or study of watches and timepieces) by the 1630s and the first horologists (the practitioners of horologiography) appeared to have emerged (or at least first advertised themselves) in 1795.  The noun horologe (a clock or sundial) is long obsolete.  Horology, horologiography & horologist are nouns, horological is an adjective and horologically is an adverb; the noun plural is horologists.

Greenwich Mean Time

Greenwich Mean Time (GMT) is the mean solar time at the Royal Observatory in Greenwich, London.  It’s daily reset point is now midnight but, in the past, it has been set from different times including at noon and for this reason, if GMT is of substantive importance in some historic document, it’s sometimes necessary to determine which method of calculation applied at the time.  Because of Earth's uneven angular velocity in its elliptical orbit and its axial tilt, noon (12:00:00) GMT is rarely the exact moment the Sun crosses the Greenwich meridian and reaches its highest point in the sky.  The event may occur up to 16 minutes before or after noon GMT, a discrepancy included in the calculation of time: noon GMT is thus the annual average (ie "mean") moment of this event, which accounts for the "mean" in GMT.  In the English-speaking world, GMT is often used as a synonym for Coordinated Universal Time (UTC) and while this is close enough for many practical purposes, in the narrow technical sense GMT is now a time zone rather than time’s absolute reference.  For navigation, it is considered equivalent to UT1 (the modern form of mean solar time at 0° longitude); but this meaning can differ from UTC by up to 0.9 seconds so GMT should no longer be used for purposes demanding a high degree of precision.

Shepherd Gate (slave) Clock, Royal Observatory, Greenwich.

The Shepherd gate clock is installed at the gates of the Royal Observatory in Greenwich and was the first clock ever to display GMT to the public.  It is a “slave clock”, hardwired to the Shepherd “master clock” which was first commissioned at the observatory in 1852.  One obviously unusual aspect of the gate clock is that it has 24 hours on its face rather than the typical 12, thus at 12 noon the hour hand is points straight down rather than up.  In digital timepieces are common and the user often has the choice of a 12 or 24 hour format by in analogue devices they’re historically rare although Ford Australia did include one as a novelty in the first series of its locally produced LTD & Landau (1973-1976).  The clock remained a one-off.

Lindsay Lohan wearing Rolex Datejust Blue Diamond.  Ms Lohan has a number of Rolexes and some watch sites have noted her preferences for the larger, chunkier men's versions.  That larger face is certainly easier to read but some also prefer the more extravagant look.

Between 1852-1893, the Shepherd master clock was the baseline of the UK’s system of time, its time was sent over telegraph wires to London and many other cities including some in Ireland and from 1866, the signal was also relayed to a clock in Harvard University, Cambridge, Massachusetts, along the new transatlantic submarine cable.  One of history’s most significant clocks, it originally indicated astronomical time, in which the counting of the 24 hours of each day starts at noon though this was later changed to starts at midnight.  It continues to show GMT and is never adjusted for daylight saving time.
