Dunbar

Dunbar (pronounced duhn-bahr)

(1) A proper noun (given and surnames, town & locality names et al).

(2) As Dunbar's number, a suggested cognitive limit to the number of people with whom one can maintain stable social relationships (those in which an individual knows who each person is and how each person relates to every other person).

Pre 1100: From a Boernician family in ancient Scotland who are the ancestors of those who first used the name Dunbar. They lived in the barony of Dunbar on the North Sea coast near Edinburgh. The construct of the place name is from the Gaelic dùn (a fort) + barr (top; summit).  The surname Dunbar was created by the eleventh century barony of Dunbar in the Lothians, created when Cospatrick fled to Scotland after being deprived of his Earldom of Northumberland by William the Conqueror.

Dunbar’s Number

British anthropologist Robin Dunbar (b 1947) explored the idea there might be a relationship between brain size and social group size through his studies of non-human primates.  This ratio was mapped using neuroimaging and the observation of time devoted to important social behaviour among primates.  Dunbar concluded that the size (relative to body mass) of the neocortex (the part of the brain associated with cognition and language) is linked to the size of a cohesive social group.  This ratio is a measure of the complexity a social system can handle.

Using this mathematical model, Dunbar applied the principle to humans, examining historical, anthropological and contemporary psychological data about group sizes, including how big groups get before they fragment, split off or collapse, finding a remarkable consistency around the number one-hundred and fifty (150).  The 150 number appears to apply to early hunter-gatherer societies and an array of more modern formations: offices, communes, factories, residential campsites, military organisations, medieval English villages and even Christmas card lists.  Where the number exceeds 150, network cohesion reduces.

Others have done research in this area and their theories tend to suggest the tightest circle has just 5 (loved ones) followed by successive layers of 15 (close friends), 50 (friends), 150 (meaningful contacts), 500 (acquaintances) and 1500 (those you can recognise).  People migrate in and out of these layers, but the idea is that space has to be carved out for any new entrants.  Dunbar offered no suggestion why these layers exist in multiples of five, but noted it did seem fundamental to monkeys and apes and most research indicated this was replicated in human relationships.  Dunbar’s 150 number is contested within the discipline although most in the field concur there probably is a Dunbarian number.  However, reducing it to a mean value may not be a helpful model of social interaction because connections aren’t normally distributed (shaped like a bell curve), a few people with massive or tiny numbers of contacts tending to distort the result.  There are also critiques on methodological grounds. Primates’ brain sizes are influenced by other aspects besides social complexity and social capacity can be stretched in different cultural settings, especially with the advent of newer technologies.

There are friends and there are followers and there is no such thing as a Dunbar number for followers; one can certainly suffer a surplus of "friends" but one can never have too many "followers".

People had friends before there was Facebook but the platform’s use of “friends” as the original prime identifier of a linkage with another did annoy those who thought “acquaintances” should have been offered as an alternative and had Facebook’s founders known what was to come, they might have done things a little differently.  However, because of Facebook’s origins as a parochial system peculiar to a single educational institution, the use of “friend” at the time certainly reflected the purpose and the approach was little difference to the other embryonic social media platforms early in the twenty-first century.  Once deconstructed, the structural similarities between Facebook, Bebo, Friendster, hi5 and MySpace were quite striking but Facebook flourished and the others did not.  There were many reasons for this but Facebook certainly benefited from learning from the mistakes of those who came first and their product offered a better experience for users who clearly preferred ease of navigation and simplicity of use compared to extensive (and not always intuitive) configurability.  Having a large group of Harvard University students as a beta test group proved invaluable and unlike others, what Facebook had from day one of its general release was a product which was inherently global and scalable.

Had the evolution of the socials been predictable, Facebook might well from the start have had “customers” and “acquaintances” as well as “friends” and it probably would also have allowed the addition of “followers”, now one of the core measures in the ecosystem.  The difference between “friends” and “followers” is that friends are presumed to enjoy a mutual connection and the establishment of the relationship needs mutual consent while followers may attach themselves of their own volition; friends are thus symmetrical, followers inherently an asymmetric concept although it’s known many Facebook accounts have friend counts which suggest the user is accumulating them essentially as followers.

“Friend” has before been used in novel (frankly Orwellian) ways.  The head of the Nazi SS (the Schutzstaffel (protection squad), a paramilitary formation which became an economic empire and in wartime eventually morphed into a parallel army close to a million-strong), Heinrich Himmler (1900–1945; Reichsführer SS 1929-1945), also coordinated an interesting aggregation of individuals and institutions styled the Freundeskreis Reichsführer SS (Circle of Friends of the Reichsführer SS (FRFSS)).  The origins of the FRFSS lay in the Freundeskreis der Wirtschaft (Circle of Friends of the Economy), a kind of combination of think tank and slush fund, the money provided by those in industry or the finance sector who either wished to support the party or anticipated them gaining power and wished to be on the winning side.  Himmler’s power grew during the 1930s but many of his grand designs (a good number of them crackpot schemes) hadn’t proceeded beyond the planning stage because of a lack of funds, the resources of the state directed primarily towards re-armament.  In re-constituting the Circle of Friends of the Economy as the FRFSS, funds became available on the basis of mutual interest, Himmler as the coordinator of repression in the Nazi state able to use the SS to deliver cheap labor (mostly from concentration camps) in exchange for the money and technical assistance he needed to build the economic enterprises he intended to create to make the SS independent of the state.  In this hunt he faced some competition from others, notably Hermann Göring (1893–1946; leading Nazi 1922-1945, Hitler's designated successor & Reichsmarschall 1940-1945) who led an expensive lifestyle as well as needing money for his industrial empire.  Himmler’s Dunbar number has never been certain but it’s believed the number of friends in the FRFSS never exceeded a few dozen.

Theodolite

Theodolite (pronounced thee-od-l-ahyt)

(1) In surveying, a precision instrument having a telescopic sight for establishing horizontal and sometimes vertical angles; usually called a transit in US & Canada.

(2) As phototheodolite, an instrument consisting of a theodolite mounted on a camera which can take at each of several stations of known position and elevation (as determined by transit survey) a series of photographs used in terrestrial photogrammetry.

1571: From the New Latin theodolitus the origin of which is contested.  It was probably coined either from the Arabic al-idhâda (a sort of rule) or the Ancient Greek theā (a viewing) plus a second element of unknown origin which may have been invented.  The North American use of” transit” rather than theodolite is historic.  During the nineteenth century, Americans preferred the surveyor’s compass and, later, the surveyor’s transit, which were cheaper and more robust and, despite technical progress, the name stuck.

Many have attempted to trace the etymology of theodolite but no satisfactory explanation has been found.  The first use was in a book by English mathematician and surveyor Leonard Digges called Geometrical practical treatize, named Pantometria, diuided into three bookes, longimetria, planimetria, and stereometria (1571, second edition 1591).  The author didn’t mention any derivation and used the spellings “theodelitus” and “theodolitus” alternately.  Writing a few years later, another mathematician named the same instrument a “horizontall or flatte sphere”, although inconsistencies in spelling was at the time not unusual, the same author when speaking of an alidade (a sighting device or pointer for determining directions or measuring angles used in both surveying and astronomy), spelled it as “alideday” and “athelida”.

One explanation is that both theodelitus and athelidae were corruptions of the Arabic al-idhâda (a sort of rule), and both mathematicians would have been acquainted with the work of earlier Arabic mathematicians.  That’s not unconvincing for athelidae but theodelitus is more likely to have been derived from (or at least influenced by) the Ancient Greek; the second element has mystified all.  The first part of the New Latin theo-delitus might stem from the Ancient Greek θεᾶσθαι (to behold or look attentively upon) or θεῖν (to run) but the second part is puzzling though sometimes attributed to an unscholarly variation of one of the following Greek words: δῆλος (evident; clear), δολιχός (long) or δοῦλος (slave) or even an unattested Neo-Latin compound combining ὁδός (way) and λιτός (plain).  It has been also suggested that -delitus is a variation of the Latin supine deletus, in the sense of "crossed out".

From mechanical to digital

Copper & brass theodolite, Hall Brothers of London, circa 1894.

A theodolite is an optical device used to measure angles between visible points in the horizontal and vertical planes.  Historically they were used in land surveying but they’re used also in all aspects of civil engineering, meteorology and rocket telemetry.  The earliest theodolites were small mounted telescope which rotated horizontally and vertically; modern versions are sophisticated digital instruments which can track weather balloons, airplanes, and other moving objects, at distances up to 12 miles (20 km / 65,600 feet).  Nearly always used mounted on a tripod and originally mechanical-optical instruments, almost all theodolites in active use are now digital.  Theodolites, whether mechanical or digital, are instruments used to determine the relative position of points on the earth's surface by measuring the horizontal and vertical angles. Digital theodolites are more convenient and accurate as they provide the operator with readouts.  With the traditional device, it was necessary manually to read the numbers directly from a graduated circle.

The modern digital theodolite.

A digital theodolite consists of a telescope mounted on a base, a sight at the top used to align the target, vision of which is clarified by adjusting a focusing knob, an objective lens on the opposite side used to sight and magnify the target as required.  Despite the differences in construction, the parts of a digital theodolite are mostly similar to the non-digital theodolite, except for the addition of a liquid crystal display (LCD) and the operating keys for changing the settings.  In the same manner as the non-digital theodolite, leveling is performed using optical plummets or plumb bobs and the spirit or bubble level.  In use, it’s made first to stand vertically above the survey point with the help of a plumb bob or optical plummet and is then made in level to the horizon with the help of internal spirit levels.  Once the leveling process is complete, the telescope is used to focus on the target and the respective horizontal and vertical angles are displayed on the screen.

Skeuomorph

Skeuomorph (pronounced skyoo-uh-mawrf)

(1) An ornament or design on an object that mimics the form of the object when made from another material or by other techniques, usually one that reflects a previously functional element.

(2) In digital technology. a design or design element, as an icon on a digital device, that mimics the three-dimensional look or the sound of a physical object, even if that object is obsolete.

1889: The construct was the Ancient Greek σκεῦος (skeûos) (implement, tool, vessel) + μορφή (morphḗ) (shape; form), modeled after the earlier zoomorph (resembling an animal) and phyllomorph (resembling a plant).  The suffix -morph was appended to words to denote “of or pertaining to shape or structure”.  Skeuomorph & skeuomorphism are nouns, skeuomorphic is an adjective and skeuomorphically is an adverb; the noun plural is skeuomorphs.

Magic Cap's start-up screen (1994).

The classic desktop metaphor, built with skeuomorphs, which was the start-up screen for the Magic Communicating Applications Platform (1994-2001 and commonly known as Magic Cap), an operating system for personal digital assistants (PDA) constructed wholly in the object oriented programming (OOP) model.  Loaded with good ideas and ahead of its time, Magic Cap failed because the planet's communication infrastructure was neither robust enough or sufficiently fast to realize the OS's possibilities.  Additionally, even as things evolved, there was never enough inter-operability with other systems and services which had achieved critical mass.

A skeuomorph is a design element in an object which mimics the design of a similar object made from another material or serving another function; it can thus be considered a derivative object which retains visual cues from the original object.  Quite when the idea emerged of the skeuomorph as something which consciously and deliberately “carries over” an earlier motif for some purpose beyond the functional is uncertain but in engineering and architecture, the technique pre-dates Antiquity.  Because architectural generations (expressed usually as eras or epochs) tend to extend over at least several human generations, what comes to be defined as “attractive” or “elegant” can become well-established but as technological advances make possible structures which are bigger, taller or able to be created with different materials or in different shapes, it had been common for motifs like familiar visual elements to be (explicitly or in detail) to be included in the new.  It softened the shock of the new.  In domestic architecture, this continues to this day, much to the disgust of architects who are appalled at the mash-up of influences which can appear in a McMansion (in which there will be chandeliers with electric bulbs emulating wax candles; a classic skeuomorph) but since modernity was delivered with the twentieth century, in big buildings and representational architecture, the shock of the new seems to have become the objective and skeuomorphs are regarded as sentimental or worse: bourgeois.

Instagram’s old skeuomorph (left) and the new flat logo (right).

In 2018 Instagram switched its logo from a skeuomorph UI to a flat UI.  It was a move which at the time surprised many because the retro brown and cream camera with a rainbow stripe (a nod to the Polaroid cameras which were such a symbol of the late twentieth century) had become instantly recognisable but the company insisted the new design reflected how the app had changed. When first released (as Burbn), the app was used almost exclusively for its photo filters and effects that lent digital images a “retro edge”, the dominant pattern of use then to use Instagram as handler to edit images which were then uploaded to a platform such as Facebook or X (then known as Twitter).  However, Instagram clicked with generation brought up on short-form content and static images and became suddenly a massive social phenomenon.  So, the logo changed because as the company put it: “We've been inspired by all the ways the community has grown and changed, and we wanted to create something that reflects how vibrant and diverse storytelling on Instagram has become”.  Exactly how all this was reflected in the new logo was neither immediately obvious nor expanded on by Instagram but the point probably was just that it was changed, the medium being the message.  In 2012 Facebook bought Instagram for US$1 billion which now sounds a bargain but back then, a billion US$ was still a lot of money.

Skeuomorphs in action: The Lindsay Lohan Quiz for iOS.

In the more ephemeral world of screen icons, graphical user interfaces (GUI) and app design where the life of a design can be closer in duration to that of the premiership of Liz Truss (b 1975; UK prime-minister Sep-Oct 2022) than something like Westminster Abbey, skeuomorphs proved popular because instantly they could adopt symbols which were unambiguous and universally understood; the sense of continuity with the past really wasn’t important at all, the retro-look just amusing.  Although using a representation of an old-style rotary-dial telephone on a screen icons does sound paradoxical, it made sense because the symbol was internationally recognized whereas were an image of cell phone (mobile) to be used, it would not have worked as well because it could be easily confused with a calculator or some other rectangular device.  Equally, envelopes and mail-boxes were used where E-mail was involved because nothing else could possibly be so evocative of “mail”.

Among software designers, the dominant theme in the early skeuomorphs was to create panels with a 3D appearance to gain some resemblance to physical buttons.  This was at least partially because designers tend wherever possible to exploit to the maximum whatever is permitted by the medium which is their platform but it was also partly the persuasive utility of the skeuomorph itself.  The alternative approach was the “flat design” which deliberately avoided imitating real-world textures or objects, a paradigm inherited from a school of art and design which rejected the idea of one thing imitation another.  Imitation however thrived, thus smartphones have digital cameras which produce the audible sound of a mechanical shutter when a photograph is taken and note-taking apps may emulate the appearance (in 2D) of textured bond paper.  The trends come and go and no approach has ever seemed to be dominant, both motifs (and hybrid forms) peacefully co-existing, frequently on the one device although in recent years things do seem to have moved to the darker and more minimalist.

Pre 1000: From the Middle English noun and adjective purple, purpel & purpur, from Old English purpuren & purpul, a dissimilation (first recorded in Northumbrian, in the Lindisfarne gospel) of purpure (purple dye, a purple garment), from the adjective purpuren (purple; dyed or colored purple), from purpura (a kind of shellfish, Any of various species of molluscs from which Tyrian purple dye was obtained, especially the common dog whelk; the dye; cloth so dyed; splendid attire generally), from the Ancient Greek πορφύρα (porphýra or porphura) (the purple fish (Murex)), perhaps of Semitic origin.  Purpur continued as a parallel form until the fifteenth century and was maintained in the rules of heraldry until well into the nineteenth.  The verb purple (to tinge or stain with purple) was from the noun and emerged circa 1400.  The earlier form was purpured, a past-participle adjective.  The adjective purplish (somewhat purple, tending to purple) was from the noun and dates from the 1560s.  Purple is a noun, verb & adjective, purpled & purpling are verbs, purplish, purpler, purply & purplest are adjectives and purpleness is a noun; the noun plural is purples.

The rhetorical use in reference to “the splendid; the gaudy” began as a description of garments (classically imperial regalia) and since the mid-eighteenth century, as “purple prose” of writing.  In US political discourse and commentary, purple has since been used (often in graphical or cartographic form) to indicating the sectional or geographical spaces in which the increasing division of the country into red (Republican) and blue (Democratic) was less apparent.  That this came into widespread use only by around 2004 is because the use of red & blue by the US news media became (more or less) standardized only by the 1990s, use have begun circa 1980, something without any relationship to the linking of the colors (red=left; blue=right) traditional in other parts of the English-speaking world.  Other words used to describe purplish shades include lavender, mauve, amethyst, violet (with many sub-types) lilac, orchid, indigo, mulberry, plum, eggplant (aubergine seems rare but is used in commerce), fuchsia, heliotrope, periwinkle, purpureus & thistle and while many directly reference the flowers of plants, one curiosity is magenta: It was so called because the dye of that shade was created at the time of the Battle of Magenta (1559) in which French and Sardinian forces defeated those of the Austrians.  Purple is widely used in zoology and botany to create common names of species to some extent colored purple.

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, Sub Lime, Sassy Grass, Panther Pink, Moulin Rouge, Top Banana, Lemon Twist & Citron Yella.  Although it may be an industry myth, the story told was that Plum Crazy & In-Violet (lurid shades of purple) were late additions because the killjoy board refused to sign-off on Statutory Grape.  The lurid colors soon disappeared, not only because fashions change but because at the time they depended on the use of lead which was banned from paint in the early 1970s.  Not until the early twenty-first century did manufacturers perfect ways economically to replicate the earlier colors without using lead.

In idiomatic use, purple is popular.  One “born into the purple” was literally one of royal or exalted birth although it’s now often used even of those from families somewhere in the upper middle class.  The “purple death” was hospital slang for Spanish influenza and it was an allusion to the cyanosis which, because of the difficulty breathing, which would turn the skin purple.  In the early post-war years “purple death” was also used to describe a cheap Italian wine.   The phrase “once in a purple moon” was a variation of “once in a blue moon” and some dictionaries include an entry, apparently only for the purpose of assuring us that not only is it extinct but it may never have been in common use.  “Purple bacteria” (the form only ever used in the plural) are a proteobacteria which produce their own food using photosynthesis; they are all classed as purple, even though some are orange, red or brown.  In the analogue-era world of the phone phreaks (hackers who used the telephone networks for other than the intended purpose), a “purple box” was a device which added a hold facility to a telephone line.  It was an allusion to the general term “black box” used in engineering and electronics to describe small devices with specific purposes; not all “purple boxes” were actually purple.  “Purple gas” was a Canadian term which described the gas (motor spirit; petrol) colored with a purple dye to indicate it was sold subject to a lower rate of taxation and for use only in agriculture and not on public roads.  Anyone found using “purple gas” beyond a farm could be charged and many countries use similar methods though the dye is not always purple.  “Purple gold” was a synonym of amethyst gold (a brittle alloy of gold and aluminium, purple in colour).

A “purple passage” (also as “purple prose”) was any form of writing thought showy or overwrought, using an exaggerated array of literary devices and effects or marked by excessively ornate rhetoric.  It was a criticism but the later “purple patch” which describes any particular good period or performance (in any context) was wholly positive.  The “purple pill” was an advertising slogan used by a pharmaceutical company but unlike “little blue pill” (Viagra), it never entered the vernacular.  “Purple plague” has specific meanings in chemistry and electronics (relating to a chemical reaction which produces an undesirable purple compound) but a more amusing use is by Roman Catholic bishops noting a unwanted number of monsignors (who wear a purple sash) in their dioceses, sent there by the Vatican.  In US politics a “purple state” is a “swing state”, one which, depending on this and that, may vote either Republican (red) or Democrat (blue).  The “purple star” was the symbol worn by Jehovah's Witnesses in concentration camps in Nazi Germany (1933-1945), one of a number of color-coded patches, the best-known of which was the yellow Jewish star.  The Jehovah's Witnesses were an interesting case in that uniquely among the camp inmates, they could at any time leave if they were prepared to sign a declaration denying their religious beliefs.  In international air-traffic management, a “purple zone” (also “purple airway”) describes a route reserved for an aircraft on which a member of a royal family is flying.  In US military use, the “Purple Heart” dating from 1932, is still awarded to service personnel wounded in combat.  It’s origin was a decoration in purple cloth first awarded in 1782 which came to be known as the “wound stripe”.  In the mid 1960s, “purple haze” was slang for LSD (Lysergic acid diethylamide, a psychedelic drug with a long history verging on academic respectability before becoming a popular hallucinogenic, users clipping the term to "acid"); it was later repurposed for various strains of weed.

Lindsay Lohan, admirer of all things purple.

The dye tyrian purple (all the evidence suggests it would now be thought a crimson), was produced around Tyre and was prized as dye for royal garments, hence the figurative use in the sixteenth century of purple for “imperial or regal power” (it was also the color of mourning or penitence among royalty or the upper reaches of the clergy).  Tyrian purple (also known as shellfish purple) was for long periods the most expensive substance in Antiquity (often (by weight) three times the value of gold, the exchange rate set by a Roman edict issued in 301 AD.  By the fifteenth century when the intricate process to extract and process the dye was lost, Tyrian purple had for millennia been variously a symbol of strength, sovereignty and money and its use had spread from the Classical world to Southern Europe, North Africa, and Western Asia and was so associated with the civilization of the Phoenicians (the color named after their city-state Tyre) that they were known as the “purple people”.  What many didn’t know was that the dye associated with the illustrious came not from a gemstone or some vivid coral but from the slimy mucous of sea snails in the Murex family.  Debate continues about what must have been the process used in extraction and production although, given many factories and artisans were involved over the years, there may have been many variations of the method.

It was in 1453 when the Byzantine capital Constantinople (modern-day Istanbul) fell to the Ottomans that the knowledge of Tyrian purple was lost, something of a footnote to the end of the Eastern Roman Empire but still a loss.  Then, the infamously smelly dyeworks of the old city were the hub of purple production although, after a series of punitive taxes, the Catholic Church had lost control of the pigment which is the origin of the pope’s decision that red would become the new symbol of Christian power and this was adopted for the garb of cardinals; the story that the vivid red symbolized the blood cardinals mush be prepared to spill in the defense of their pope was just a cover story although one obviously approved of by the pontiff.

Beginning in 1968 with Shades of Deep Purple (left), the rock band Deep Purple sometimes used purple-themed album cover art and may have wished they'd stuck with that their eponymous third album (1969).  The original cover (centre), featuring a fragment of one panel of the triptych The Garden of Earthly Delights (1490-1510) by Hieronymus Bosch (circa 1450-1516), was declared "demonic" by the US distributors so an alternative needed hastily be arranged and whether because of the tight schedule or just wanting to play it safe, they stuck to purple (right).  They'd earlier had a similar difficulty with their US label when releasing their second album (The Book of Taliesyn (1968)), the objection that time that one song title (Wring That Neck) was "too violent" (it was an instrumental piece and the reference was to a technique used with the neck of a guitar but it was anyway changed to Hard Road).  Times have changed.

Mnemonic

Mnemonic (pronounced ni-mon-ik)

(1) Something assisting or intended to assist the memory.

(2) Pertaining to mnemonics or to memory.

(3)In computing, truncated code thought easy to remember (eg STO for store).

1660–1670: From the New Latin mnemonicus from the Ancient Greek μνημονικός (mnēmonikós) (of memory) derived from μνήμων (mnḗmōn) (remembering, mindful) & μνᾶσθαι (mnâsthai) (to remember); the ultimate root was the primitive Indo-European men (to think).  The meaning "aiding the memory", a back-formation from mnemonics dates from 1753, the noun meaning "mnemonic device" is from 1858.  The use in computer programming emerged in the early days of code and was a space-saving (eg del rather than delete) tool as well.  Mnemonical was the original form from the 1660s.

Sans Forgetica

Sans Forgetica sample text.

Recently released, Sans Forgetica (which translates as "without forgetting") is a sans-serif font developed by RMIT University in Melbourne.  Back-slanted and with gaps in the character constructions, it’s designed explicitly to assist readers better to understand and retain in their memory what they’ve read.  Perhaps counter-intuitively for those outside the field, the shape is intended to reduce legibility, thereby (1) lengthening the tame taken to read the text and (2) adding complexity to learning and absorbing what’s been read.  Together, they create what in cognitive psychology and neuroscience is called "desirable difficulty", in this case forcing (RMIT might prefer "nudging") people to concentrate.

The first three paragraphs of Lindsay Lohan's Wikipedia page, rendered in Sans Forgetica.  Sans was from the Middle English saunz & sans, from the Old French sans, senz & sens, from the Latin sine (without) conflated with absēns (absent, remote).   Forgetica was an opportunistic coining, the construct being forget + -ica.  Forget was from the Middle English forgeten, forgiten, foryeten & forȝiten, from the Old English forġietan (to forget) (which was influenced by the Old Norse geta (to get; to guess), from the Proto-West Germanic fragetan (to give up, forget).  The -ica suffix was from the Latin -ica, the neuter plural of -icus (belonging to derived from; of or pertaining to; connected with).

From usually a young age, readers become skilled at scanning text, a process helped by most publishers seeking to render their works as legible as possible.  The theory of desirable difficulty is that omitting parts of the font requires the reader to pause and process information more slowly, thus provoking an additional cognitive processing which may enhance both understanding and retention.  While the application of the science to a font is novel, there’s nothing original about Sans Forgetica as a piece of typography, it being described as a hybrid of several existing schools and within the theory, on the basis of a small-group sample of students, it’s claimed to be a balance between legibility and difficulty.  According to the documents supplied by the developer, it’s not been tested as a device for advertisers to draw people to their text, the theory of that being people scan and dismiss (without retention) the great bulk of the large, static signage which is a feature of just about every urban environment.  With Sans Forgetica, because it can’t as quickly be scanned, people will tend longer to linger and so more carefully read the whole; a memorable event itself.

Flachkühler

Flachkühler (pronounced flak-koo-ler)

In German, (literally wide cooling device (radiator)), a name adopted by Daimler-Benz to describe the W111 Mercedes-Benz coupés and cabriolets built (1969-1971) with a lower, wider radiator grill than the earlier W111 (and W112) coupés and cabriolets (1961-1969).

Circa 1860s: The construct was Flach + kühler.  The adjective flach (the singular flacher, the comparative flacher and the superlative flachsten) (shallow (wide and not deep)) was from the Middle High German vlach, from the Old High German flah, from the Proto-Germanic flakaz of uncertain origin.  The construct of the noun Kühler ((1) cooler (anything device which cools) or (2) radiator (of an internal combustion engine) was kühlen +‎ -er.  Kühlen was from the Middle High German küelen, from the Old High German kuolōn & chuolen, from the Proto-Germanic kōlōną & kōlēną and related to kalaną (to be cold).  It was cognate with the Hunsrik kiele, the Luxembourgish killen, the Dutch koelen, the Saterland Frisian köile, the English cool (verb) and the Swedish kyla.  The German suffix -er (used to forms agent nouns etc from verbs (suffixed to the verb stem)) was from the Middle High German -ære & -er, from the Old High German -āri, from the Proto-West Germanic -ārī, from the Proto-Germanic -ārijaz, from the Latin -ārius.  When used as an adjective, kühler was a comparative degree of kühl ((1) cool (of temperature), (2) calm, restrained, passionless and (3) cool, frigid (particularly of the emotions)), from the Middle High German küele, from the Old High German kuoli, from the Proto-West Germanic kōl & kōlī, from the Proto-Germanic kōluz & kōlaz, from the primitive Indo-European gel-.  It was cognate with the Dutch koel and the English cool.  Flachkühler is a noun; the noun plural is Flachkühlers.

The dimensions of the grill used on the Mercedes-Benz W111 coupé & cabriolet was dictated by the height of the three litre straight six (M189) engine used in the more exclusive W112 (300 SE) versions.  The M189 was one of several de-tuned variants of the M198 used in the 300SL Gullwing & Roadster (W198) which had started life as the M186 in the big 300 (W186, “Adenauer”) saloon before revealing it’s competition potential by gaining victories at the Nürburgring, the Carrera Panamericana in Mexico and, most famously, the 24 Hours of Le Mans.  In the sports cars, the long-stroke six had been installed at an angle of 50^o and fitted with a dry sump which permitted a low hood (bonnet) line but in the W111 & W112 the engine was in a conventional perpendicular arrangement and used a wet sump, further adding to the height, thus the relatively tall grill.  The smaller sixes used in the car (2.2 litre (M127); 2.5 (M129) & 2.8 (M130)) were of a more modern, short-stroke design and didn’t demand such a capacious engine bay but production line rationalization didn’t make viable two different sets of coachwork for what were low volume models.

1971 Mercedes-Benz 280 SE 3.5 Coupé (Flachkühler)

By the mid 1960s however, Mercedes-Benz realized their gusty, high-revving sixes were technologically bankrupt and for success in the vital US market, they needed a mass-market V8.  Their big-block 6.3 litre V8 (M100), introduced in 1963 with the 600 Grosser (W100) wasn’t suitable for down-sizing so a physically smaller range was developed, the first of which was designated M116; released in 1969 and in displacements of 3.5, 3.8 & 4.2 litres, it would serve the line until 1991.  The 3.5 came first and in 1969 it was fitted to the W111 coupé & cabriolet.  By then, the old 3.0 litre six had been discontinued so the tall grill, which by then had come to look rather baroque, as no longer required and the factory took the opportunity to modernize things and the new, lower wider grill came to be known as the Flachkühler (literally “flat cooler” and best translated as “flat radiator”, the engineers deciding the earlier design should be referred to as the Hōchkühler (high radiator).  Hōch (high, tall; great; immense; grand; of great importance) was from the Middle High German hōch, from the Old High German hōh, from the Proto-West Germanic hauh, from the Proto-Germanic hauhaz, from the primitive Indo-European kewk-, a suffixed form of kew-; it may be compared to the Dutch hoog, the English high and the Swedish hög.

Because of the first oil shock in 1973, the plans for mass-market (a relative term) Mercedes-Benz V8s were interrupted for a while but the 3.5 litre W111s had already reached the end of the line before the embargo began.  Produced only until 1971, they were always expensive and only 3,270 coupés and 1,232 cabriolets were built and, it being another age, they were available with a four-speed manual gearbox, an option a few actually choose.  The Mercedes-Benz manual gear-change was a rather clunky thing but such is rarity value, they have a cult following.  The whole ecosystem of 280 SE 3.5 coupés and cabriolets is actually a cult in itself, perfectly restored cabriolets commanding prices in excess of US$500,000 and some German tuning houses will charge even more for examples modernized with attributes like ABS, later V8 engines, transmissions and suspension.  Even now, although in essence the structure dates from the late 1950s and the mechanicals a decade later, the appeal remains because the things are remarkably usable in modern conditions and ascetically, nothing Mercedes-Benz has made since has anything like the elegance.

Strangely, the idea of the “flat radiator” had been around for a while in the vernacular of collector car circles but it referred to another aspect of geometry.  In 1952, Morgan of Malvern Link, Worcestershire, was (as it is now) a cottage industry manufacturing pre-war sports cars with more modern engines and they received advice from the manufacturer of their separate headlight assemblies that because MG’s new TF (due for release in 1953) would have its headlamps integrated into the bodywork, production of the housing was ending.  There being no alternative supplier, Morgan were compelled to follow MG’s lead restyle things so the headlamps were faired in.  Concurrent with this, the Morgan factory took the opportunity to do one of their rare styling changes, abandoning their long-establish upright radiator grill one mounted in a cowl that blended into the hood (bonnet).  It wasn’t exactly the onset of modernity but there presumably was some aerodynamic gain.  Just to assure buyers change wasn’t being made for the sake of change, disc brakes would have to wait another few years.  The change to the grill was made in 1953 although, because of the way Morgan operated, some of the older style cars were actually assembled later than the new.  The cars with the traditional Morgan look which features the upright grill are known among aficionados as the “flat radiator Morgans”.

Impromptu Flachkühler: In October 2005, Lindsay Lohan went for a drive in her Mercedes-Benz SL65 AMG.  There was a low-speed unpleasantness with a van which caused the roadster to suffer a Flachkühler.

Appoggiatura

Appoggiatura (pronounced uh-poj-uh-too-r-uh or uh-poj-uh-tyoo- r-uh or ahp-pawd-jah-too-rah (Italian))

In musical composition, an ornament consisting of a non-harmonic note (short or long) preceding a harmonic one either before or on the stress (a note of embellishment preceding another note and taking a portion of its time).

1745-1755: From the Italian appoggiatura, from appoggiare (to lean; to prop; to support) from the Vulgar Latin appodiāre (present active infinitive of appodiō, from the Classical Latin podium) and related to the French appuyer, the Spanish apoyar and the Portuguese apoiar.  The meaning in music is for the sense of one note “propping up” another.

The Appoggiatura

As in many fields, fashions in music change.  There was a period, during the sixteenth century, when the rules of counterpoint were strict and discords permissible only if they were prepared and resolved in ways used in the previous sections; the only discord normally allowed on the strong beat was the suspension.  There the discord is prepared by the note being tied across from a weak to a strong beat and resolved onto the next weak beat; a type of syncopation.  In the mid-century however, there was a relaxation of the rules of voice leading which included experimentation with unprepared discords, the most important of which was the appoggiatura.  The appoggiatura started as a decorative note which displaced the first part of a note of a melody.  It occurred on the strong beat of the bar and could be either dissonant or consonant but in either case, the appoggiatura resolved (upwards or downwards) onto a consonance but, unlike the suspension, did not require to be prepared or tied from a previous note.  In order to overcome the earlier rule that all discords had to be prepared, the appoggiatura was originally shown as an ornament but later was written out in full.

An ornament: Bach, Orchestral Suite in B minor for flute and strings: Menuet.

That was just a fudge, a composer paying respect to a rule while breaking it because, as played, an appoggiatura is not a short ornament, it takes usually up a full half of the length of the note that it resolves onto and if resolved onto a note three beats long, it takes up a third or two thirds the length.  The appoggiatura is usually connected with the main harmony note by a slur and is normally played with a small degree of emphasis.

Haydn: Sonata in G major XVI:27 Allegro con Brio.

Haydn shows appoggiaturas at *1, *2 and *3, now written out in-full as was normal practice in the classical period. Their identity as elaborating notes is given away by the presence of the slurs.

The two superstars of the 1950s.  Maria Callas (1923-1977)  and Marilyn Monroe (1926-1962), back-stage after the "Happy Birthday Mr President" performance, Madison Square Garden, New York, 19 May 1962.  Within three months, Marilyn Monroe would be dead.

December 2 2023 marked the hundredth anniversary of the birth of the singer Maria Callas, the soprano who remains still more famous than any other and the subject of a cult, something attributable certainly to her art but the tempestuous life she led off the stage attracted many; in the very modern sense of the word, Callas was a celebrity.  What Callas is in 2023 is thus a construct, a mix of myth, discography, and public persona although it’s more correct to say she’s a number of constructs; the criteria of trained musicians and critics likely to differ from those who just listen.  She was neither the most technically accomplished nor the most refined singer and yet, as Sir Rudolf Bing (1902–1997; General Manager of the Metropolitan Opera in New York (the Met)) famously noted, “having once heard Callas, it was difficult to listen to anyone else sing the same music”.  That was because whatever the technical flaws or deliberate departures from what had become the accepted techniques of the mid-twentieth century, Callas brought to every performance a thrilling intensity which made the characters come alive in a way even the most virtuosic of her contemporaries couldn’t quite match.

The critics impressed only by technical ecstasy liked to label Callas a “singing actress” and there’s something in that but not in the way they mean; the “acting” wasn’t there to compensate for the voice, it was a part of the voice.  There are several recordings of the “madness” scene in Gaetano Donizetti's (1797–1848) Lucia di Lammermoor (1835) in which, as an exercise in singing, the performances are more accomplished yet it’s the Callas version which is the definitive because only she can send a shiver down the spine.  It was in the interpretation, just as it was when, in Giuseppe Verdi’s (1813–1901) Otello (1886), she played with layers of vocal tones variously to convey feelings of warm nostalgia, paranoia, depression and impending death.  Whatever was in the score to be expressed, it’s there but it wasn’t done with vocal pyrotechnics, indeed Callas, in both studio recordings and live performances often eschewed the cadential trills and appoggiature which, although unwritten, had entered Opera in the seventeenth century and become a signature of sopranos since at least the early nineteenth.  What she did with her voice has been called a kind of “operatic word-painting”, a lending of emotional depth which enabled her, more than any other to transcend the theatrical artificiality of opera and it’s this quality which means even roles for which she seemed an improbable choice (such as Giacomo Puccini’s (1858–1924) Madam Butterfly (1904)) demand attention.
