Dwarf

Dwarf (pronounced dwawrf)

(1) A person of abnormally small stature owing to a pathological condition, especially one suffering from cretinism or some other disease that produces disproportion or deformation of features and limbs.  In human pathology, dwarfism is usually defined, inter-alia, as an adult height less than 1.47 m (4 ft 10 in).

(2) In zoology & botany, an animal or plant much smaller than the average of its kind or species.

(3) In European folklore, a being in the form of a small, often misshapen and ugly, man, usually having magic powers.

(4) In Norse mythology, any member of a race of beings from (especially Scandinavian and other Germanic) folklore, usually depicted as having some sort of supernatural powers and being skilled in crafting and metalworking, often as short with long beards, and sometimes as clashing with elves.

(5) In astronomy, a small version of a celestial body (planet, moon, galaxy, star etc).

(6) Of unusually small stature or size; diminutive; to become stunted or smaller.

Pre 900: From the Middle English dwerf, dwergh, dwerw & dwerȝ, from the Old English dweorh & dweorg (dwarf), replacing the Middle English dwerg and ultimately from the Proto-Germanic dwergaz.  It was cognate with the Scots dwerch, the Old High German twerg & twerc (German Zwerg), the Old Norse dvergr (Swedish dvärg), the Old Frisian dwirg (West Frisian dwerch), the Middle Low German dwerch, dwarch & twerg (German & Low German Dwarg & Dwarch) and the Middle Dutch dwerch & dworch (Dutch dwerg).  The Modern English noun has undergone complex phonetic changes. The form dwarf is the regular continuation of Old English dweorg, but the plural dweorgas gave rise to dwarrows and the oblique stem dweorge which led to dwery, forms sometimes found as the nominative singular in Middle English texts and in English dialects.  Dwarf is a noun and verb, dwarfness & dwarfishness are nouns, dwarfish & dwarflike are adjectives and dwarfishly is an adverb.  The plural forms are dwarves and dwarfs.  Dwarfs was long the common plural in English but after JRR Tolkien (1892-1973) used dwarves, his influence was enough to become the standard plural form for mythological beings.  For purposes non-mythological, dwarfs remains the preferred form.

The M Word

1970 MG Midget.

Dwarf seems still to be an acceptable term to describe those with dwarfism and Little People of America (LPA), the world’s oldest and largest dwarfism support organization (which maintains an international, membership-based organization for people with dwarfism and their families) has long campaigned to abolish the use of the word “midget” in the context of short humans.  The objection to midget is associative.  It was never part of the language of medicine and it was never adopted as official term to identify people with dwarfism, but was used to label used those of short stature who were on public display for curiosity and sport, most notoriously in the so-called “freak shows”.  Calling people “midgets” is thus regarded as derogatory.  Midget remains an apparently acceptable word to use in a historic context (midget submarine, MG Midget et al) or to describe machinery (midget car racing; the Midget Mustang aerobatic sports airplane) but no new adoptions have been registered in recent years.  The LPA is also reporting some supportive gestures, noting with approval the decision of the Agricultural Marketing Service (AMS) of the US Department of Agriculture’s (USDA) to revise the nomenclature used in the US standards for grades of processed raisins by removing five references to the term “midget”.  Although obviously a historically benign use of the word, its removal was a welcome display of cultural sensitivity.

An interesting outlier however is midget wrestling, a field in which the participants are said enthusiastically to support the label, citing its long traditions and the marketing value of the brand.  Although in the late twentieth century, midget wrestling’s popularity diminished in the last decade there’s be a resurgence of interest and the sport is now a noted content provider for the streaming platforms which run live and recorded footage.  Since the 1970s, midget wrestling has included styles other than the purely technical form with routines extending from choreographed parody and slapstick performances to simulated sexual assault.  These innovations have attracted criticism and the suggesting it’s a return to the freak shows of earlier centuries but audiences in the target demographic seem appreciative and, noting the success of a number of tours and operators, Major League Wrestling in 2022 announced the creation of a midget division.

The short stature of Victor Emmanuel III (1869–1947; King of Italy 1900-1946) with (left to right), with Aimone of Savoy, King of Croatia (Rome, 1943), with Albert I, King of the Belgians (France, 1915), with his wife, Princess Elena of Montenegro (Rome 1937) & with Adolf Hitler (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945), observing navy manoeuvres (Gulf of Naples, 1938).  Note his sometimes DPRKesque hats.

Technically, Victor Emmanuel didn’t fit the definition of dwarfism which sets a threshold of adult height at 4 feet 10 inches (1.47 m), the king about 2 inches (50 mm) taller (or less short) and it’s thought the inbreeding not uncommon among European royalty might have been a factor, both his parents and grandparents being first cousins.  However, although not technically a dwarf, that didn’t stop his detractors in Italy’s fascist government calling him (behind his back) il nano (the dwarf), a habit soon picked up the Nazis as der Zwerg (the dwarf) (although Hermann Göring was said to have preferred der Pygmäe (the pygmy)).  In court circles he was know also, apparently affectionately as la piccola sciabola (the little sabre) a nickname actually literal in origin because the royal swordsmith had to forge a ceremonial sabre with an unusually short blade for the diminutive sovereign to wear with his many military uniforms.  His French-speaking Montenegrin wife stood a statuesque six feet (1.8 m) tall and always called him mon petit roi (my little king).  It was a long and happy marriage and genetically helpful too, his son and successor (who enjoyed only a brief reign) very much taller although his was to be a tortured existence.  Still, in his unhappiness he stood tall and that would have been appreciated by the late Duke of Edinburgh who initially approved of the marriage of Lady Diana Spencer (1960-1997) to the Prince of Wales (b 1948) on the basis that she “would breed some height into the line”.

In cosmology, the word dwarf is applied to especially small versions of celestial bodies.  A dwarf galaxy is a small galaxy of between several hundred and several billion stars, (the Milky Way may have as many as billion) and astronomers have identified many sub-types of dwarf galaxies, based on shape and composition.  A dwarf planet is a small, planetary-mass object is in direct orbit of a star, smaller than any of the eight classical planets but still a world in its own right.  Best-known dwarf planet is now Pluto which used to be a planet proper but was in 2006 unfortunately down-graded by the humorless types at the International Astronomical Union (IAU) who are in charge of such things.  It’s hoped one day this decision will be reversed so Pluto will again be classified a planet.  Dwarf planets are of interest to planetary geologists because despite their size, they may be geologically active bodies.  The term dwarf star was coined when it was realized the reddest stars could be classified as brighter or dimmer than our sun and they were created the categories “giant star” (brighter) and dwarf star (dimmer).  As observational astronomy improved, the

With the development of infrared astronomy there were refinements to the model to include (1) the dwarf star (the “generic” main-sequence star), (2) the red dwarf (low-mass main-sequence star), (3) the yellow dwarfs are (main-sequence stars with masses comparable to that of the Sun, (4) the orange dwarf (between a red dwarf and yellow/white stars), (5) the controversial blue dwarf which is a hypothesized class of very-low-mass stars that increase in temperature as they near the end of their main-sequence lifetime, (6) the white dwarf which is the remains of a dead star, composed of electron-degenerate matter and thought to be the final stage in the evolution of stars not massive enough to collapse into a neutron star or black hole, (7) the black dwarf which is theorized as a white dwarf that has cooled to the point it no longer emits visible light (it’s thought the universe is not old enough for any white dwarf to have yet cooled to black & (8) the brown dwarf, a sub-stellar object not massive enough to ever fuse hydrogen into helium, but still massive enough to fuse deuterium.

Coolest dwarf of all is (9) the ultra-cool dwarf (first defined in 1997), somewhat deceptively named for non cosmologists given the effective temperature can be as high as 2,700 K (2,430°C; 4,400°F); in space, everything is relative.  Because of their slow hydrogen fusion compared to other types of low-mass stars, their life spans are estimated at several hundred billion years, with the smallest lasting for about 12 trillion years.  As the age of the universe is thought to be only 13.8 billion years, all ultra-cool dwarf stars are relatively young and models predict that at the ends of their lives the smallest of these stars will become blue dwarfs instead of expanding into red giants.

The events towards the conclusion of the nineteenth century German fairy tale Snow White and the Seven Dwarfs make ideal reading for young children.  Her evil step-mother has apparently killed poor Snow White so the seven disappointed dwarfs lay her body in a glass coffin.  The very next, a handsome prince happens upon the dwarfs’ house in the forest and is so captivated by her beauty he asks to take her body back to his castle.  To this the dwarfs agree but while on the journey, a slight jolt makes Snow White come to life and the prince, hopelessly in love, proposes and Snow White accepts.  Back at the palace, the prince invites to the wedding all in the land except Snow White's evil stepmother.

Another sleeping beauty: Snow White and the Seven Dwarfs.

The step-mother however crashes the wedding and discovers the beautiful Snow White is the bride.  Enraged, she attempts again to kill her, but the prince protects her and, learning the truth from his bride, forces step-mother to wear a pair of red-hot iron slippers and to dance in them until she drops dead.  That takes not long and once she drops dead, the wedding ceremony resumes.  The prince and Snow White live happily ever after.

DEI (diversity, equity and inclusion)

The condition achondroplasiaphobia describes those with a “fear of little people".  The construct is achondroplasia (the Latin a- (not) +‎ the Ancient Greek chondro- (cartilage) + the New Latin‎ -plasia (growth); the genetic disorder that causes dwarfism) + phobia (from the New Latin, from the Classical Latin, from the Ancient Greek -φοβία (-phobía) from φόβος (phóbos) (fear).  The condition, at least to the extent of being clinically significant, is thought rare and like many of the especially irrational phobias is induced either by (1) a traumatic experience, (2) depictions in popular culture or (3) reasons unknown.  Achondroplasiaphobia has never appeared in the American Psychiatric Association’s (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM).  In 2006, it was reported that while dining at the Chateau Marmont hotel in Los Angeles, after noticing two people of short stature had entered the restaurant, Lindsay Lohan suffered an "anxiety attack" and hyperventilated to the extent she had to take "an anti-anxiety pill" to calm down.  To her companions she repeatedly said "I’m so scared of them!"  A spokesperson for the LPA responded by suggesting Ms Lohan should "...treat her fear the same as she would a fear of any other protected minority population.  If that fails, she might find diversity training to be useful."  Almost immediately the story appeared, a representative for Ms Lohan debunked the story, saying she is not achondroplasiaphobia and is not scared of little people, adding "Lindsay loves all people."

Circa 1200: From the Middle English deltha from the Latin delta from the Ancient Greek δέλτα (délta), from the Phoenician dalet & daleth (tent door).  It was akin to the Hebrew dāleth.  It was the fourth letter of the Greek alphabet (equivalent to the Modern English D) and was shaped like a triangle (Δ).  The sense of a delta being a "triangular island or alluvial tract between the diverging branches of the mouth of a great river" is because the Ancient Greek writer Herodotus (circa 484–circa 425 BC) used it to describe the mouth of the Nile River (now known as the Nile Delta).  That was picked up in English during the 1550s and applied to other river mouths (often of quite different shapes) by 1790.  The related forms are deltaic and deltification.  In pre-modern medicine, the deltoid muscle (the large muscle of the shoulder; triangular, resembling the Greek letter delta) was described in 1758, the name from the Ancient Greek deltoeides (triangular, literally "shaped like the letter delta).  In modern use, the "deltoid muscle" gained the short-form “delts” in 1977.  The related form is deltoidal.

The delta-wing

Gloster Javelin (1951-1967).  The first twin-engined delta-wing in service, the Javelin was the UK’s long-term solution to its need for an all-weather interceptor, the post-war technology gap until then filled by the stop-gap Gloster Meteor and that most improbable cold-war fighter, the de Havilland Mosquito.  The Javelin was the last aircraft to bear the Gloster name, the company absorbed into the morass created by the mergers, acquisitions and nationalization that befell British industry between Attlee and Thatcher. 

In aviation, the delta shape pre-dated aircraft by centuries, triangular stabilizing fins for rockets described in the sixteenth and seventeenth centuries and the first lifting wing in delta form patented in 1867 for use by a dart-shaped, rocket-propelled airplane.  However, although there were prototypes and much theoretical work was done during the first half of the twentieth century, it wasn’t until the late-1940s when jet propulsion made possible high-speed subsonic and supersonic flight that it was possible to build airframes which could take advantages of the delta-wing’s unique properties.

Lockheed SR-71 Blackbird (1963-1999).  A product of Lockheed’s Skunk Works, although in development as a high-altitude interceptor since 1959, the US government didn’t admit the SR-71 existed until 1964 and decided ultimately to use it for reconnaissance and research into supersonic flight.  The SR-71 in 1976 set the world record for the fastest flight by an air-breathing manned aircraft and the mark still stands.

The delta form offers structural advantages and aerodynamic characteristics suited to the fluid dynamics of airflow in supersonic conditions.  To suit different applications, design variations have evolved, with and without additional stabilizing surfaces.  The long root chord of the delta wing and minimal structure outboard is inherently structurally efficient, able to be built stronger and stiffer yet lighter than a swept wing of equivalent lifting capability.  It’s thus simple and relatively inexpensive to build.

Avro Vulcan (1956-1984).

Until the UK adopted the submarine-launched Polaris missile system, the Vulcan was the platform for the UK’s independent nuclear deterrent and it remained in service long enough to be deployed for its only combat mission, a flight of five aircraft used for (conventional bombing) missions during the 1982 Falklands War.  Each aircraft flew almost 4000 miles  (6,500 km) from Ascension Island, Victor tankers used for the air-to-air refueling, almost 1.1 million gallons (5 million litres ) of fuel burned each mission.

The long root chord also allows a deeper structure for a given aerofoil section, providing more internal volume for fuel and other storage without a significant increase in drag although, on supersonic designs, designers often take the opportunity to use a thinner aerofoil instead, thereby further reducing drag.  Usefully, the large root chord also provides a large surface area which assists in reducing the minimum speed; a low landing speed being a design objective in most military and civil applications.  Delta wings can be designed to induce vortex lift, so flow separation can be turned into a means of increasing lift and the whole structure is naturally stable in pitch, therefore not requiring a separate tail surface.

Aérospatiale/BAC Concorde (1969-2003).

The Anglo-French supersonic passenger jet operated commercially between 1976-2003.  Flying at twice the speed of sound and carrying up to 128 passengers, it was the longest lasting of its time, the Soviet Tupolev Tu-144 in passenger service only for a few years during the 1970s after which it operated both as a freighter and a research platform and the American SST never progressed beyond engineering mock-ups.  The Americans worked out the economics were never going to make sense; the Soviets had a different relationship to money and the Concorde lasted as long as it did only because the French & British governments wrote-off the development costs.

There are drawbacks.  The large wing area creates more viscous drag for the same amount of lift compared to a high aspect ratio wing; swept wings have a better lift-to-drag ratio than deltas.  Also, high-lift devices like fowler flaps are hard to integrate into delta wings with the rearward location of the trailing edge producing intolerable pitching moments when such flaps would be deflected.  In short, delta wings are superior only in supersonic flight; their best known design probably the Anglo-French Concorde.

Lindsay Lohan in delta skirts.

A delta skirt is characterized by its triangular shape, an allusion to the Greek letter delta (Δ); almost always, a delta skirt is fitted at the waist, flaring out towards the hem, creating the triangular silhouette.  The concept is adaptable and can be made from just about any fabric, the most popular including cotton, taffeta, silk and a variety of other synthetics.  Delta skirts tend to be shorter because to produce the triangular effect as length increases either some sort of internal structure is required or additional material needs to be used, increasing bulk and weight.  Although most associated with younger women, they have been adopted by a number sub-sets from the anime aesthetic, Goths and bohemians to hippies.

Gunk

Gunk (pronounced guhngk) 

(1) Any sticky or greasy residue or accumulation.

(2) A sub-culture of twenty-first century US males, combining elements of the modern gothic culture with punk rock.

(3) In mereology, any whole, the parts of which have further proper parts.

1949:  An Americanism, used to describe (usually dirty or unwanted) viscous substances, derived from Gunk, the trademark for a degreasing solvent, a thick liquid soap patented in 1932 by the AF Curran Company of Malden, Massachusetts.  Origin of the name is wholly speculative, the most likely offerings being (grime + funk) or (grime + junk).  Disgusting gunk has many synonyms:  quagmire, goo, silt, slime, muck, sludge, gunk, waste, debris, trash, powder, mud, mucus, grease, sediment, residue, grit, smoke, ash, dirt, oily, filth.

Gunk in Mereology

Gunk Engine Degreasant.

In mathematical logic and philosophy, mereology is the study of parts and the wholes they form.  Unlike set theory, the basis of which is the relation between a set and its elements, mereology is about the meronomic (part-whole relationships).  In mereology, gunk is any whole, the parts of which have parts and because parts are intrinsically transitive, any part of gunk must also be gunk, the implication of which is that gunk cannot contain any (indivisible) single-point parts.  So, for it to operate as it does, the known universe depends on gunky stuff like time.  Immediately controversial because of its challenges to nihilism, the term was first applied by Princeton philosopher David Lewis (1941-2001) in his 1991 publication, Parts of Classes.  Lewis claimed traces of the ideas could be found in writings from antiquity, through René Descartes (1596–1650) to Bertrand Russell (1872-1970); others found this lineage “arguable”.  Lewis’ mind worked in abstract space.  His construct of realism was (1) possible worlds exist, (2) every possible world does exist, (3) any possible world is wholly separate from any other and (4), our world is one of the possible worlds.
