Planet

Planet (pronounced plan-it)

(1) In astronomy (now also as “major planet), any of the eight large spherical bodies revolving about the sun in elliptical orbits and shining by reflected light: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, or Neptune, in the order of their proximity to the sun.

(2) A similar body revolving about a star other than the sun.

(3) A celestial body moving in the sky, as distinguished from (the apparently fixed) stars, applied also to the sun and moon (obsolete except in historic reference).

(4) In astrology, the sun, moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, or Pluto: regarded as sources of energy or consciousness in the interpretation of horoscopes.

1250-1300: From the Middle English planete, from the late Old English planete, from the Old French planete (which endures in Modern French as planète), from the Latin planeta & planetes (found only in plural planētae), from the Ancient Greek πλανήτης (plantēs) (wanderer), (ellipsis of πλάνητες στέρες (plánētes astéres (literally “wandering stars”)), from the Ancient Greek πλανάω (planáō) (to wander about, to stray), from planasthai (to wander), of uncertain etymology.  It was cognate with the Latin pālor (to wander about, to stray), the Old Norse flana (to rush about), and the Norwegian flanta (“to wander about”); from here English ultimately gained flaunt.  The source may have been a nasalized form of the primitive Indo-European root pele- (flat; to spread) on the notion of "spread out" but it’s speculative, etymologists noting a similarity of meaning in the Greek plazein (to make devious, repel, dissuade from the right path, bewilder) the evidence simply doesn’t exist to permit a conclusion to be drawn.  Planets were originally so-called because, viewed by the astronomers from Antiquity, they display apparent motion, unlike the stars which seemed “fixed” in space, the word derived from the Ancient Greek phrase plánētes astéres (literally “wandering stars”), ultimately from planasthai (to wander).  Thus the earliest definitions of planets encompassed both the Moon and Sun but not the Earth.  The sense define by modern science of a “world which orbits a star" was first noted in English in the 1630s.  It wasn’t until the Copernican revolution that the Earth was recognized as a planet, and the Sun was seen to be fundamentally different.

The noun planetoid (one of the asteroids, or minor planets, revolving about the sun between the orbits of Mars and Jupiter) is from 1803, the adjectival form planetoidal adopted in 1809.  Strangely, there’s never been an accepted definition of planetoid.  Within astronomical circles, it was initially a synonym for asteroid, "asteroid" referring to the star-like image seen through a telescope while "planetoid" described the object’s planet-like orbit.  In the literature, by the early twentieth century “planetoid” and “asteroid” were both widely used but the latter had prevailed almost wholly by the late 1970s.  This decline in use as a synonym is because it had instead become handy as a word to describe a subset of the larger members of the asteroid community, used to mean “planet-like in form or geology”.  Improvements in observational capacity in the early twenty-first century saw a surge in use as so many more planetary bodies were discovered in the Kuiper belt and beyond.  Within the astronomical community, there was a consensus most were hardly asteroids and concomitant with doubts as to the appropriate definition of "planet", planetoid was the label of choice.

The noun protoplanet (a large, diffuse cloud of matter in the orbit of a young star, regarded as the preliminary state of a planet) dates from 1949, the construct being proto- + planet.  The proto- prefix was a learned borrowing from the Ancient Greek πρωτο- (prōto-), a combination form of πρτος (prôtos) (first), superlative of πρό (pró) (before).  The adjective planetary (of or pertaining to a planet) was from the 1590s, probably influenced by the Late Latin planetarius (pertaining to a planet or planets) although the Oxford English Dictionary (OED) notes the only attested meaning as a noun was "an astrologer".  The planetary nebula, so-called because of the shape as seen through a telescope, is from 1785.  1690s The adjective interplanetary (existing between planets) was used in the sense of "travel between planets” as early as 1897 although the English philosopher and physician John Locke (1632–1704) used intermundane in the same sense, the Roman Epicureans having had intermundia (neuter plural) for "spaces between the worlds", translating from the Ancient Greek metakosmia.  Mundane was from the Middle English mondeyne, from the Old French mondain, from the Late Latin mundanus, from the Classical Latin mundus (world).  The noun planetarium (orrery, astronomical machine which by the movements of its parts represents the motions and orbits of the planets) dates from 1734 and was a creation of Modern Latin, the construct being the Late Latin planeta + Latin -arium (a place for).  The modern meaning "device for projecting the night sky onto the interior of a dome" describe the device developed by the optical engineering company Zeiss in Germany; it was first demonstrated in Munich in 1923, the word planetarium adopted in English in 1929.

The Galileian satellites of Jupiter were initially called satellite planets but were later reclassified along with the Moon.  The first observed asteroids were also considered planets, but were reclassified when became apparent how many there were, crossing each other's orbits, in a zone where only a single planet had been expected.   Pluto was found where an outer planet had been expected, but doubts were soon raised about its status because (1) it was found to cross Neptune's orbit and (2) was much smaller than the expectation had suggested.  The debate about the status of Pluto went on for decades after its discovery in 1930.  The pro-planet faction may have become complacent, thinking that because Pluto had always been a planet, it would forever be thus but, after seventy-six years in the textbooks as a planet, the International Astronomical Union (IAU) in 2006 voted to re-classify Pluto as a dwarf planet on the basis that the icy orb failed to meet a set of criteria which the IAU claimed had been accepted for decades.

To be a planet, the IAU noted, the body must (1) orbit a sun, (2) be sufficiently massive to it pull itself into a sphere under its own gravity and (3), "clear its neighborhood" of debris and other celestial bodies, proving it has gravitational dominance in its corner of the solar system.  Pluto fails the third test.  Because it orbits in the Kuiper Belt (a massive ring of asteroids and planetoids that stretches beyond the orbit of Neptune), Pluto is surrounded by thousands of other celestial bodies and chunks of debris, each exerting its own gravity.  Pluto is thus not the gravitationally dominant object in its neighborhood and therefore, not a planet and but a dwarf, a sort of better class of asteroid.  The IAU’s action had been prompted by the discovery in the Kuiper Belt of a body larger than Pluto yet still not meeting the criteria for planethood.  Feeling the need to draw a line in the cosmos, the IAU dumped Pluto.

However #plutoisaplanet is a thing and Pluto’s supporters have a website, arguing that while it’s universally accepted a planet should be spherical and orbit the Sun, the "clearing the neighborhood" rule is arbitrary, having appears only in a single paper published in 1801.  The history is certainly muddied, Galileo having described the moons of Jupiter as planets and there are plenty of other more recent precedents to suggest the definitional consensus has bounced around a bit and there are even extremists really to accept the implications of loosening the rules such as the moons of Earth, Jupiter and Saturn becoming planets.  Most however just want Pluto restored.

The most compelling argument however is probably just that the IAU are a bunch of humorless cosmic clerks, something like the Vogons ("...not actually evil, but bad-tempered, bureaucratic, officious and callous.") in Douglas Adams' (1952–2001) Hitchhiker's Guide to the Galaxy (1979-1992) and that Pluto should be restored to planethood because of the romance.  Although lacking the lovely rings of Saturn (a feature shared on a smaller scale by Jupiter, Uranus & Neptune), Pluto is the most charming of all because it’s so far away; desolate, lonely and cold, it's the solar system’s emo.  If for no other reason, it should be a planet in tribute to the scientists who, for decades during the late nineteenth and early twentieth centuries, calculated possible positions and hunted for the elusive orb.  In an example of Donald Rumsfeld's (1932–2021; US secretary of defense 1975-1977 & 2001-2006) “unknown knowns”, the proof was actually obtained as early as 1915 but it wasn’t until 1930 that was realized.  In an indication of just how far away Pluto lies, since the 1840s when equations based on Newtonian mechanics were first used to predict the position of the then “undiscovered” planet, it has yet to complete even one orbit of the Sun, one Plutonian year being 247.68 years long.  The name "Pluto" was from the Roman god of the underworld, from the Classical Latin Pluto & Pluton, from the Ancient Greek Πλούτων (Ploútōn) (god of wealth) from ploutos (wealth; riches (probably originally "overflowing" from the primitive Indo-European pleu- (to flow).  It was the alternative Greek name or epithet of Hades in his function as the god of wealth (precious metals and gems, coming from beneath the earth, form part of his realm).

Mercury

Mercury (pronounced mur-kyuh-ree)

(1) In chemistry, a heavy, silver-white, highly toxic metallic element (uniquely liquid at room temperature), once widely used in barometers & thermometers and still a component of pesticides & pharmaceutical preparations.  In industrial use it provides the reflecting surface of mirrors, can still be a part of dental amalgams and is used in some switches, mercury-vapor lamps, and other electric apparatus.  It’s also used as a catalyst in laboratories.  Symbol: Hg; atomic weight: 200.59; atomic number: 80; specific gravity: 13.546 at 20°C; freezing point: 38.9°C; boiling point: 357°C.  It’s known also as quicksilver or hydrargyrum.

(2) In clinical pharmacology, the metal as used in various organic and inorganic compounds, used usually to treat infections of the skin.

(3) In mythology, the Roman god who served as messenger of the gods and was also the god of commerce, thievery, eloquence, and science, identified with the Greek god Hermes (initial capital letter).

(4) In astronomy, the planet nearest the sun, having a diameter of 3,031 miles (4,878 km), a mean distance from the sun of 36 million miles (57.9 million km), and a period of revolution of 87.96 days, and having no satellites; the smallest planet in the solar system (diameter and mass: respectively 38 and 5.4% that of earth) (initial capital letter).

(5) Borrowing from mythology, a messenger, especially a carrier of news (largely archaic).

(6) In botany, any plant belonging to the genus Mercurialis, of the spurge family, especially the poisonous, weedy M. perennis of Europe.  Historically, it was most associated with the annual mercury (Mercurialis annua), once cultivated for medicinal properties (the fourteenth century French mercury or herb mercury).

(7) In botany, a similar edible plant (Blitum bonus-henricus), otherwise known since the fifteenth century as English mercury or allgood.

(8) In botany, in eighteenth century US regional use, the poison oak or poison ivy.

(9) In the history of US aerospace, one of a series of U.S. spacecraft, carrying one astronaut and the first US vehicle to achieve suborbital and orbital manned spaceflights (initial capital letter).

(10) Liveliness, volatility (obsolete since the mid-nineteenth century).

1300–1350: From the Middle English Mercurie, from the Medieval Latin, from the Classical Latin Mercurius (messenger of Jupiter, god of commerce) and related to merx (merchandise),  Mercury, mercuriality & mercurialist are nouns, mercurial is a noun & adjective, mercurous, intramercurial & mercuric are adjectives and mercurially is an adverb; the noun plural is mercuries.

The late fourteenth century adjective mercurial (pertaining to or under the influence of the planet Mercury) evolved by the 1590s to include the sense “pertaining to the god Mercury, having the form or qualities attributed to Mercury (a reference to his role as god of trade or as herald and guide)”.  The meaning “light-hearted, sprightly, volatile, changeable, quick” was in use by the 1640s and was intended to suggest the qualities supposed to characterize those born under the planet Mercury, these based on the conduct of the god Mercury (which seems a generous interpretation given some of his antics), probably also partly by association with the qualities of quicksilver. A variant in this sense was the now rare noun mercurious, in use by the 1590s.  The adjective mercuric (relating to or containing mercury) dates from 1828 and in chemistry applied specifically applied to compounds in which each atom of mercury was regarded as bivalent.  Mercurous was by the 1840s applied to those in which two atoms of mercury are regarded as forming a bivalent radical. 

In the mythology of Antiquity, the Roman Mercury (or Mercurius) was identified with the Greek Hermes, protecting travelers in general and merchants in particular.  He was depicted as the messenger of Jupiter and in some tales even as his agent in some of Jupiter’s amorous ventures (famously in Amphytrion (circa 188 BC) by the playwright Titus Maccius Plautus (circa 254–184 BC)).  The location of Rome’s first Temple of Mercury was chosen because it was so close to both the port and the commercial precinct, the god of commerce thus well-placed.  Although it’s not entirely certain, the structure was thought to date from 496 BC and historians note the sanctuary was built outside the pomerium (the city’s religious boundary), leading to speculation the cult may have been of foreign origin.  Mercury’s attributes included the caduceus (the wand), a variety of very fetching broad-brimmed hats, winged sandals (essential for one so “fleet of foot” and the purse (symbolizing the profits merchants gained from their trade).  The tales from Antiquity are not consistent (and in some cases contradictory but Mercury in some traditions was the father of Evander or of Lares (charged with the supervision of crossroads and prosperity); Lares was born after Mercury raped Lara, the water Nymph in the kingdom of the dead.  The identification of Mercury with the Greek Hermes was ancient but in the early medieval period he was linked also with the Germanic Woden and noting his role as a messenger and conveyor of information, since the mid-seventeenth century Mercury was often used as a name for newspapers although has been a common name for a newspaper and some critics have adapted it for their own purposes: In Australia the Hobart Mercury was in the 1980s sometimes derisively called the “Hobart Mockery”.

The origin of the chemical name of mercury (Hg) reflects the influence of Scientific Latin on early-modern chemistry; Hg is an abbreviation of the Latin name of the element: hydrargium (literally “water-silver”), from the Ancient Greek hydrargyros (liquid silver), an allusion to its unique quality of being a silvery liquid when at room temperature (all other metals being solid).  The older English name was quicksilver (still prevalent in literary & poetic circles) which was coined in the sense of “living silver”, a reference to the liquid tending to move “like a living thing” when provoked with the slight provocation.  The “quick” referred not to speed but “alive” in the sense of the Biblical phrase “the quick and the dead”.  Alchemists called it azoth and in medical and sometimes chemical use that’s still occasionally seen.  As late as the fifteenth century, in mainstream Western science the orthodox view was that mercury was one of the elemental principles thought present in all metals.  In Antiquity, it was prepared from cinnabar and was then one of the seven known metals (bodies terrestrial), coupled in astrology and alchemy with the seven known heavenly bodies (the others: Sun/gold, Moon/silver, Mars/iron, Saturn/lead, Jupiter/tin, Venus/copper.  In idiomatic use, (with a definite article), because of the use in barometers & thermometers, “the mercury” was a reference to temperature thus “mercury rising” meant “warmer”, the use dating from the seventeenth century and it has persisted even as the devices have moved to digital technology.  The name mercury was adopted because the stuff flows quickly about, recalling the Roman god who was the “swift-footed messenger of the gods”.

The same rationale appealed to the astronomers of Antiquity who noted the swift movement of the planet which required only 88 days for each solar orbit.  Mercury is sometimes visible from the Earth as a morning or evening star and in our solar system and is the both the smallest and the closest planet to the Sun.  Second in density only to Earth, it’s a lifeless (as far as is known or seems possible) place with a cratered surface which makes it not dissimilar in appearance to Earth's Moon.  It behaves differently from Earth in that the rotational period of 58.6 days is two-thirds of its 88-day annual orbit, thus it makes three full axial rotations every two years.  The atmosphere is close to non-existent, something which, combined with the rotational & orbital dynamics and the proximity to the Sun produces rapid radiational cooling on its dark side, meaning the temperature range is greater than any other planet in our solar system (466°-184°C (870°-300°F)).  Being so close to the Sun, Mercury is visible only shortly before sunrise or after sunset, observation further hindered by Earth’s dust & pollution, this distorting the planet’s light which obliquely must pass through the lower atmosphere.  It wasn’t until circa 1300 that the Classical Latin name for the planet was adopted in English while a (presumably hypothetical) resident of the place was by 1755 a Mercurian or a century later as Mercurean.  The novel adjective intramercurial (being within the orbit of the planet Mercury) was coined in 1859 to describe a hypothetical planet orbiting between Mercury and the Sun.  The idea had existed among French astronomers since the 1840s but became a matter of some debate between 1860-1869 until observations of solar eclipses finally debunked the notion.  The origin of the noun amalgamation (act of compounding mercury with another metal), dating from the 1610s, was a noun of action from archaic verb amalgam (to alloy with mercury), the figurative, non-chemical sense of “a combining of different things into one uniform whole” in use by 1775.

Genuinely different and obvious a cut above a Ford: 1939 Mercury 8 Coupe.

Reflecting the philosophy of Henry Ford which put a premium on engineering and price, concepts like product differentiation & multi-brand market segmentation came late to the Ford Motor Company.  Unlike General Motors (GM) which throughout the 1930s fielded seven brand-names, it wasn’t until 1938 that Ford added a third, using until then just Ford and Lincoln and even they operated as separate companies whereas GM maintained a divisional structure.  The debut in 1938 of the Mercury label, sitting on the pricing scale between Ford and Lincoln made sense in a way that twenty years on, Edsel never did and, until internal cannibalization began in the 1960s, the Mercury brand worked well.  Even after that, the marketing momentum accrued over decades maintained Mercury’s viability and it wasn’t shuttered until 2011, a victim of the industry’s restructuring after the Global Financial Crisis (GFC 2008-2012).  Debatably, the Mercury brand may yet prove useful and, should a niche emerge, there may be a resurrection, Ford maintaining registration of the trademark.

A (slightly) better Ford LTD: 1969 Mercury Marquis Brougham four-door hardtop.

Perhaps it was the experience of GM which had discouraged Ford.  Although Harvard had begun awarding MBAs since 1908, history unfortunately doesn’t record whether any of them were involved in the brand-name proliferation decision of the mid 1920s which saw the introduction of companion offerings to four of GM’s five existing divisions, only the entry-level Chevrolet not augmented.  The new brands, slotted above or below depending on where the perceived price-gap existed, mean GM suddenly was marketing nine products in competition with Ford offering two and one probably didn’t need a MBA to conclude only one approach was likely correct.  As things turned out, GM’s approach was never given the chance fully to explore the possibilities, the effects of the Great Depression of the 1930s suppressing demand in the economy to an extent then unknown, necessitating downsizing in just about every industrial sector.  Axed by GM in 1931 was Viking (Oldsmobile’s companion), Marquette (added to Buick) and Oakland (actually usurped by its nominal companion, Pontiac).  LaSalle (a lower-priced Cadillac) survived the cull… for a while.

Ford in the late 1930s had clearly been thinking about how to cover the widely understood "price-points" in the market, most of which existed between the mass-market Fords and the Big Lincolns, then a very expensive range.  One toe in the water of brand-proliferation was the creation in 1937 of "De Luxe Ford" which, despite some of the hints in the advertising, was neither a separate company nor even a division; it was described by historians of the industry as "a marque within a marque".  Structurally, this seems little different to the approach the company had been using since 1930 when it introduced a “Deluxe” trim option for certain models which could be ordered to make the “standard” Ford a little better appointed but the 1937 De Luxe Fords were more plausibly different because some relative minor changes to panels and detailing did make the two “marques” visually distinct.  The Deluxe vs De Luxe spelling was perhaps too subtle a touch to be noticed by many.

1968 Mercury Cougar GT-E 427.  The tennis court hints at the target market.

A long wheelbase Food Mustang with a higher specification, the original Mercury Cougar (1967-1970) was the brand's great success story.  The 1968 GT-E 427 was a tiny part of that but is remembered as the last use of the Le Mans winning 427 cubic inch (7.0 litre) V8 and the corporation's only 427 pony-car.  Civilized with hydraulic valve lifters and an automatic transmission, it was a glimpse of what might have been had Ford, as it once planned, put the 427 in a Mustang.     

The De Luxe Ford line was deliberately positioned between Ford and Lincoln but intriguingly, at the same time, Ford introduced both a new, lower priced V12 Lincoln called the Lincoln-Zephyr and the Mercury range, all three of these ventures contesting the same, now crowded, space.  The De Luxe Ford “marque” would last only until 1940 although Ford’s Deluxe option remained on the books; it’s doubtful many outside Ford’s advertising agency noticed.  It would seem Ford was hedging its bets and may have decided to persist with whichever of Mercury and De Luxe Ford proved most successful and as things transpired, that was Mercury so as the 1941 model year dawned, in the dealers’ brochures there were Fords, Mercurys, Lincoln-Zephyrs & Lincolns.  World War II of course intervened and when production resumed after the end of hostilities, that was simplified to Fords, Mercury & Lincoln, remaining that way until the mid-1950s when in a booming economy, the temptation to proliferate proved irresistible and the exclusive Continental division was created, followed by the infamous Edsel, the model spread of which over-lapped the pricing of both Ford and Mercury, an approach which seems to go beyond hedging.  The Continental experiment lasted barely two seasons and the Edsel just three, the latter a debacle which remains a case study in marketing departments.

A natural Mercury: 1955 Ford Thunderbird.

So by 1960 the corporation again offered just Fords, Mercurys & Lincolns but it was a troubled time for the latter, the huge Lincolns of the late 1950s, although technically quite an achievement in body engineering, had proved so unsuccessful that Ford’s new management seriously considered closing it down as well but it was saved when handed a prototype Ford Thunderbird coupé which was developed into the famous Lincolns of 1961-1969, remembered chiefly for the romantic four-door convertibles and being the cabriolet in which John Kennedy (JFK, 1917–1963; US president 1961-1963) was assassinated.  That was one of the Thunderbird’s footnotes in corporate history, the other being that when introduced in 1955 it was the first Ford blatantly to intrude on what, according to marketing theory, should have been the domain of Mercury, home of the up-market offerings.

Cannibalizing the corporation: 1965 Ford LTD.

The Thunderbird though was just the first act of trespass and fancier Fords continued to appear, the landmark being the LTD, which began in 1965 as a luxury trim-package for the Galaxie, something which proved so popular it soon became model in its own right, encouraging a host of imitators from the mass-market competition, the most successful of which was Chevrolet’s Caprice (that innovation in retrospect the first nail in the coffins of the now shuttered Pontiac & Oldsmobile).  However, like Pontiac & Oldsmobile, Mercury would endure for decades, all three surviving before being sacrificed in the wake of the GFC and between the debut of the LTD and the end of the line, there were many successful years but the rationale for the existence of Mercury which had been so well defined in 1938 when there was genuine product differentiation and a strict maintenance of price points, gradually was dissipated to the point that with the odd exception (such as the wildly successfully Mercury Cougars of the late 1960s), Fords and Lincolns were allowed to become little more than competitors in the same space and the brand never developed the sort of devoted following which might have transcended the sameness.  By the twenty-first century, there were few reasons to buy a Mercury because a Ford could be ordered in essentially identical form, usually for a little less money.

Simile, Metaphor & Analogy

Simile (pronounced sim-uh-lee)

(1) A figure of speech expressing the resemblance of one thing to another of a different category usually introduced by as or like.

(2) An instance of such a figure of speech or a use of words exemplifying it.

1393: From the Middle English simile, from the Latin simile (a like thing; a comparison, likeness, parallel), neuter of similis (like, resembling, of the same kind).  The antonym is dissimile and the plural similes or similia although the latter, the original Latin form, is now so rare its use would probably only confuse.  Apart from its use as a literary device, the word was one most familiar as the source of the “fax” machine, originally the telefacsimile and there was a “radio facsimile” service as early as the 1920s whereby images could be transmitted over long-distance using radio waves, the early adopters newspapers and the military.

The simile is figure of speech in which one thing is explicitly compared to another, usually using “like” or “as”; both things must be mentioned and the comparison directly stated.  For literary effect, the two things compared should be thought so different as to not usually appear in the same sentence and the comparison must directly be stated.  Dr Johnson (Samuel Johnson (1709-1784)) thought a simile “…to be perfect, must both illustrate and ennoble the subject." but many long ago became clichéd and far removed from nobility.

It went through me like an armor-piercing shell.
Slept like a log.
Storm in a tea cup.
Blind as a bat.
Dead as a dodo.
Deaf as a post.

Metaphor (pronounced met-uh-fawr)

(1) A figure of speech in which a term or phrase is applied to something to which it is not literally applicable in order to suggest a resemblance.

(2) Something used, or regarded as being used, to represent something else; emblem; symbol.

1525-1535:  From the Middle French métaphore & the (thirteenth century) Old French metafore from the Latin metaphora, from the Ancient Greek μεταφορά (metaphorá) (a transfer, especially of the sense of one word to a different word; literally "a carrying over”), from μεταφέρω (metaphérō) (I transfer; I apply; I carry over; change, alter; to use a word in a strange sense), the construct being μετά (metá) (with; across; after; over) + φέρω (phérō, pherein) (to carry, bear) from the primitive Indo-European root bher- (to carry; to bear children).  The plural was methaphoris.  In Antiquity, for a writer to be described in Greek as metaphorikos meant they were "apt at metaphors”, a skill highly regarded: “It is a great thing, indeed, to make a proper use of the poetical forms, as also of compounds and strange words. But the greatest thing by far is to be a master of metaphor. It is the one thing that cannot be learnt from others; and it is also a sign of genius, since a good metaphor implies an intuitive perception of the similarity in dissimilars" (Aristotle (384-322 BC), Poetics (circa 335 BC)).

The words metaphor, simile and analogy are often used interchangeably and, at the margins, there is a bit of overlap, a simile being a type of metaphor but the distinctions exist.  A metaphor is a figure of figure of speech by which a characteristic of one object is assigned to another, different but resembling it or analogous to it; comparison by transference of a descriptive word or phrase.  It’s important to note a metaphor is technically not an element or argument, merely a device to make a point more effective or better understood.  It’s the use of a word or phrase to refer to something other than its literal meaning, invoking an implicit similarity between the thing described and what is denoted by the word or phrase.  It has certain technical uses too such as the recycling or trashcan icons in the graphical user interfaces (GUI) on computer desktops (a metaphor in itself).  The most commonly used derivatives are metaphorically & metaphorical but in literary criticism and the weird world of deconstructionism, there’s the dead metaphor, the extended metaphor, the metaphorical extension, the mysterious conceptual metaphor and the odd references to metaphoricians and their metaphorization.  Within the discipline, the sub-field of categorization is metaphorology, the body of work of those who metaphorize.  

This royal throne of kings, this sceptred isle,
This earth of majesty, this seat of Mars,
This other Eden, demi-paradise,
This fortress built by Nature for herself
Against infection and the hand of war,
This happy breed of men, this little world,
This precious stone set in the silver sea,
Which serves it in the office of a wall
Or as a moat defensive to a house,
Against the envy of less happier lands,--
This blessed plot, this earth, this realm, this England.

William Shakespeare (1564-1616), Richard II (circa 1594), Act 2 scene 1.

Analogy (pronounced uh-nal-uh-jee)

(1) A similarity between like features of two things, on which a comparison may be based:

(2) A similarity or comparability.

(3) In biology, an analogous relationship; a relationship of resemblance or equivalence between two situations, people, or objects, especially when used as a basis for explanation or extrapolation.

(4) In linguistics, the process by which words or phrases are created or re-formed according to existing patterns in the language.

(5) In logic a form of reasoning in which one thing is inferred to be similar to another thing in a certain respect, on the basis of the known similarity between the things in other respects.

(6) In geometry, the proportion or the equality of ratios.

(7) In grammar, the correspondence of a word or phrase with the genius of a language, as learned from the manner in which its words and phrases are ordinarily formed; similarity of derivative or inflectional processes.

1530-1540: From the Old French analogie, from the Latin analogia, from the Ancient Greek ναλογία (analogía), (ratio or proportion) the construct being νά (aná) (upon; according to) + λόγος (logos) (ratio; word; speech, reckoning), from the primitive Indo-European root leg- (to collect, to gather (with derivatives meaning “to speak; to pick out words”).  It was originally a term from mathematics given a wider sense by Plato who extended it to logic (which became essentially “an argument from the similarity of things in some ways inferring their similarity in others”.  The meaning “partial agreement, likeness or proportion between things” fates from the 1540s and by the 1580s was common in mathematics; by the early seventeenth century it was in general English use.  The plural is analogies and the derived forms include the adjective analogical and the verbs analogize & analogized.  In critical discourse there’s the “false analogy” and the rare disanalogy.

An analogy is a comparison in which an idea or a thing is compared to another thing that is quite different from it, aiming to explain the idea or thing by comparing it to something that is familiar.  Further to confuse, metaphors and similes are tools used to draw an analogy so an analogy can be more extensive and elaborate than either a simile or a metaphor.

The day is done, and the darkness
Falls from the wings of Night,
As a feather is wafted downward
From an eagle in his flight.

Henry Wadsworth Longfellow (1807-1882), The Day Is Done (1844).

They crowded very close about him, with their hands always on him in a careful, caressing grip, as though all the while feeling him to make sure he was there. It was like men handling a fish which is still alive and may jump back into the water.

George Orwell (1903-1950), A Hanging (1931).

The Mean Girls mall scene, at the water hole in the jungle clearing where the “animals gather when on heat”.

Similes, metaphors & analogies are used frequently as devices in fiction including in Paramount Production’s Mean Girls (2004) and the similes were quite brutish including “You smell like a baby prostitute”; “She's like a Martian”; & “Your face smells like peppermint”.  The metaphors were obvious (this was a teen comedy) but worked well.  The “Plastics” implied the notion of things artificial, superficial, and shiny on the outside but hollow inside while “Social Suicide” would to the audience have been more familiar still.  The idea of the “Queen Bee” (a metaphorical position of one individual as the centre of the hive (school) around which all dynamics and activities revolve) was one of several zoological references.  The idea of it being “…like a jungle in here” was a variation of the familiar metaphorical device of comparing modern urban environments (the “concrete jungle” the best known) with a jungle and in Mean Girls stylized depictions of wild animals do appear, the school’s mascot a lion, a link to the protagonist having come from the African savanna.  There was also the use of a malapropism in the analogy “It's like I have ESPN or something”, the novelty being it used an incorrect abbreviation rather than a word.  The Mean Girls script is not the place to search for literary subtleties.

Of Pluto

The New Zealand physicist Lord Rutherford (1871-1937), who first split the atom (1932), explained its structure by drawing an analogy with our solar system.  Rutherford always regarded physics as the “only true, pure science” while other disciplines were just expressions of the properties or applications of the theories of physics.  In 1908, he was awarded the Nobel Prize in Chemistry “…for his investigations into the disintegration of the elements, and the chemistry of radioactive substances.”  It was said he was amused by the joke.

This image includes Pluto as a planet.  Historically, the Galileian satellites of Jupiter were initially called satellite planets but were later reclassified along with the Moon.  The first observed asteroids were also considered planets, but were reclassified when became apparent how many there were, crossing each other's orbits, in a zone where only a single planet had been expected.   Pluto was found where an outer planet had been expected but doubts were soon raised about its status because (1) it was found to cross Neptune's orbit and (2) was much smaller than had been the expectation.  The debate about the status of Pluto went on for decades after its discovery in 1930 and the pro-planet faction may have become complacent, thinking that because Pluto had always been a planet, it would forever be thus but, after seventy-six years in the textbooks as a planet, the International Astronomical Union (IAU) in 2006 voted to re-classify Pluto as a dwarf planet on the basis that the icy orb failed to meet a set of criteria which the IAU claimed had for decades been accepted science.

To be a planet, the IAU noted, the body must (1) orbit a star, (2) be sufficiently massive to it pull itself into a sphere under its own gravity and (3), “clear its neighbourhood” of debris and other celestial bodies, proving it has gravitational dominance (cosmic hegemony in its sphere of influence by political analogy) in its little bit of the solar system.  Pluto fails the third test.  Because it orbits in the Kuiper Belt (a massive ring of asteroids and planetoids that stretches beyond the orbit of Neptune), Pluto is surrounded by thousands of other celestial bodies and chunks of debris, each exerting its own gravity.  Pluto is thus not the gravitationally dominant object in its neighborhood and therefore, not a planet and but a dwarf (a sort of better class of asteroid).  The IAU’s action had been prompted by the discovery in the Kuiper Belt of a body larger than Pluto yet still not meeting the criteria for planethood.  Feeling the need to draw a line in the sky, the IAU dumped Pluto.

However #plutoisaplanet is a thing and Pluto’s supporters have a website, arguing that while it’s universally accepted a planet should be spherical and orbit the Sun, the “clearing the neighbourhood” rule is arbitrary, having appeared only in a single paper published in 1801.  The history is certainly muddied, Galileo having described the moons of Jupiter as planets and there are plenty of other more recent precedents to suggest the definitional consensus has bounced around a bit and there are even extremists really to accept the implications of loosening the rules such as the moons of Earth, Jupiter and Saturn becoming planets.  Most however just want Pluto restored.

The most compelling argument however is that the IAU are a bunch of humorless cosmological clerks, something like the Vogons (“…not actually evil, but bad-tempered, bureaucratic, officious and callous.”) in Douglas Adams' (1952–2001) Hitchhiker's Guide to the Galaxy (1979-1992) and that Pluto should be restored to planethood because of the romance of the tale.  Although lacking the lovely rings of Saturn (a feature shared on a smaller scale by Jupiter, Uranus & Neptune), Pluto is the most charming of all because it’s so far away; desolate, lonely and cold, it's the solar system’s emo.  If for no other reason, it should be a planet in tribute to the scientists who, for decades during the late nineteenth and early twentieth centuries, calculated possible positions and hunted for the elusive orb.  In an example of Donald Rumsfeld's (1932–2021; US secretary of defense 1975-1977 & 2001-2006) “unknown knowns”, the proof was actually obtained as early as 1915 but it wasn’t until 1930 that was realized.  In an indication of just how far away Pluto lies, since the 1840s when equations based on Newtonian mechanics were first used to predict the position of the then “undiscovered” planet, it has yet to complete even one orbit of the Sun, one Plutonian year being 247.68 years long.

Zoozve

Zoozve (pronounced zooz-vee or zooz-vay)

The orthodox clipping of 524522 Zoozve (provisional designation 2002 VE68), a temporary quasi-satellite (or quasi-moon and technically an asteroid) of the planet Venus.

2024 (sort of): From an accidental coining by a graphic artist preparing a rendering of a stylized poster of the solar system, the asteroid's provisional designation (2002VE) misread and written as ZOOZVE (the text of the descriptors all in upper case).  Another suggested pronunciation is jeuj-vey (as in zhuzh) but zooz-vee & zooz-vay seem more mnemonic.  Zoozve is a proper noun; the noun plural is zoozves.  Although Zoozve is a unique object, in the solar system, doubtlessly there are many more quasi-moons and zoozve (with an initial lower case) may emerge as the generic term, thus the need for the noun plural.

The Poster.

Zoozve first came to wider public attention early in 2024 when the tale was revealed in a podcast produced by Latif Nasser (b 1986) of New York public radio station WNYC’s RadioLab.  The story was triggered when he first noticed a detail on a poster of the solar system: a moon of Venus called Zoozve.  There are many moons in the solar system but Dr Nasser holds a PhD from Harvard's History of Science department and knew the astronomical orthodoxy was that Venus “has no moons”, something some rapid research confirmed so he contacted Elizabeth Landau (b 1975), a member of the US National Aeronautics and Space Administration's (NASA) communications, his not unreasonable assumption being if anyone should know about what’s in space, it was the folk at NASA.  After consulting the charts, Ms Landau concluded there was such an object but that it wasn’t a moon; it was a quasi-moon which, discovered in 2002, after 2004 when its dual orbits were first tracked, enjoyed the distinction of being the first quasi-moon ever found.  What appeared on the poster as “Zoozve” was the graphic artist’s misreading of “2002VE”, a designation typical of the naming conventions used in astronomy.

Poster close-up.

The distinction between a moon and a quasi moon is the former have “a primary anchor”: Although the Earth’s Moon of course revolves around the Sun as well as this planet, the solar relationship is a by-product of Earth’s gravitational pull.  A quasi-moon is one with two distinct paths of rotation, one around its (temporary) planet and one around the Sun.  There are implications in that beyond the cosmic phenomenon being a scientific curiosity: quasi-moons eventually will become detached (astronomers seem to like “flung-off” which is more illustrative) which means they could become objects which could crash into Earth.  Zoozve is some 240m (785 feet) in diameter and the conventional calculation is an impact with Earth would release energy equivalent to some 69,000 A-bombs with the yield (15 kilotons of TNT) of the device dropped on Hiroshima in 1945.  Zoozve is in the last few hundred years of its eight millennia-odd attachment to Venus and modelling suggests it is unlikely to hit earth when it does become adrift but such calculations are acknowledged to be “ultimately imprecise” and, as mentioned, there are doubtless many more; the universe is a violent and destructive place.  Quasi-moons had been speculated to exist for almost a century before 2002VE was named and since then it’s been discovered Earth has a few of its own.

2002VE was discovered in 2002 by Brian Skiff (b 1953), a research scientist at Arizona’s Lowell Observatory in Arizona and because he made no attempt to give it a “proper” name, it was allocated the procedural 2002VE86 (“proper” names granted usually only after an object has attracted sufficient interest to generate academic papers).  Dr Nasser however was so charmed by the tale of 2002VE that he submitted an application to the Working Group Small Bodies Nomenclature (WGSBN) of the International Astronomical Union (IAU) the committee responsible for assigning names to minor planets and comets.  What he wanted was for 2002VE to become Zoozve but it transpired there were naming "rules" including:

(1) 16 characters or less in length

(2) Preferably one word

(3) Pronounceable (in some language)

(4) Non-offensive

(5) Not too similar to an existing name of a Minor Planet or natural Planetary satellite.

(6) The names of individuals or events principally known for political or military activities are unsuitable until 100 years after the death of the individual or the occurrence of the event.

(7) Names of pet animals are discouraged

(8) Names of a purely or principally commercial nature are not allowed.

(9) Objects that approach or cross Earth's orbit (so called Near Earth Asteroids) are generally given mythological names.

Mar-a-Lago, Palm Beach, Florida.

Because of 2002VE’s proximity to earth, the need to have the name rooted in mythology was obviously the most onerous hurdle to overcome and it is a common-sense stipulation, imposed to avoid controversy on Earth: Imagine the fuss if quasi-moon 524522 Lindsay Lohan ended up crashing into Trump Tower or Mar-a-Lago?  There would be litigation.

Added to which, the IAU have the reputation of being a bunch of humorless cosmic clerks, something like the Vogons ("...not actually evil, but bad-tempered, bureaucratic, officious and callous.") in Douglas Adams’ (1952–2001) Hitchhiker's Guide to the Galaxy (1979-1992): they were the crew who decided Pluto should no longer be thought a planet because of some tiresome technical distinction.  Although lacking the lovely rings of Saturn (a feature shared on a smaller scale by Jupiter, Uranus & Neptune), Pluto is the most charming of all because it’s so far away; desolate, lonely and cold, it's the solar system’s emo.  If for no other reason, it should be a planet in tribute to the scientists who, for decades during the late nineteenth and early twentieth centuries, calculated possible positions and hunted for the elusive orb.  In an example of Donald Rumsfeld's (1932–2021; US secretary of defense 1975-1977 & 2001-2006) “unknown knowns”, the proof was actually obtained as early as 1915 but it wasn’t until 1930 that was realized.  In an indication of just how far away Pluto lies, since the 1840s when equations based on Newtonian mechanics were first used to predict the position of the then “undiscovered” planet, it has yet to complete even one orbit of the Sun, one Plutonian year being 247.68 years long.  Unromantic, the IAU remains unmoved.  Still, there have been exceptions to the rule and it emerged some of the “rules” are actually “guidelines” and the WGSBN was so impressed by the serendipitous tale that a majority of the committee’s eleven voting members cast their ballots for Zoozve so, on 5 February 2024, Radiolab was able to announce the IAU officially had re-designated 2002VE as 524522 Zoozve.

Truly unique words (in the sense of one-off spellings) happen for many reasons.  Those intended for global use as trademarked company or product names really do have to be unique and sufficient different to just about every other word to ensure there are no legal maneuverings contesting their registration which is how we ended up with “Optus” (used since 1991 by the Australian telecommunications company (TelCo) which is now a subsidiary of Singapore-based TelCo Singtel) and Stellantis (a conglomerate created by the merger of the Italian Fiat Chrysler Automobiles (FCA) and the French PSA Group (comprising the Peugeot, Citroën, DS, Opel and Vauxhall brands)).  While on first hearing, to many, Optus and Stellantis probably sounded like mistakes, some words really were just the result of error.  Apron (an article of clothing worn over the front of the torso and at least part of the legs and donned by (1) cooks, butchers and others as protection from spills and (2) Freemasons as part of their regalia worn during their cultish rituals was from the Middle English naperoun & napron, from the Old French napperon, a diminutive of nappe (tablecloth), from the Latin mappa (napkin).  Napron” became “apron” by the process of linguistic assimilation (ie “a napron” becoming “apron” because of the evolution of pronunciation.

Some become legion as accidental coinings only for it to turn out there’s a pedigree.  Warren Harding (1865-1921; US President 1921-1923), during the 1920 presidential campaign, used “normalcy” instead of “normality” after a George W Bush-like (George XLIII, b 1946; US president 2001-2009) mangling of the written text, something understandable because the section with the offending word was almost aggressively alliterative:

America’s present need is not heroics, but healing; not nostrums, but normalcy; not revolution, but restoration; not agitation, but adjustment; not surgery, but serenity; not the dramatic, but the dispassionate; not experiment, but equipoise; not submergence in internationality, but sustainment in triumphant nationality.

In saying "normalcy" he may have misspoken or perhaps Harding liked the word; questioned afterwards he said he found it in a dictionary which probably was true although whether his discovery came before or after the speech wasn't explored.  Although Harding’s choice was much-derided at the time, normalcy had certainly existed since at least 1857, originally as a technical term from geometry meaning the "mathematical condition of being at right angles, state or fact of being normal in geometry" but subsequently it had appeared in print as a synonym of normality on several occasions.  Still, it was hardly in general use though Harding gave it a boost and it’s not since gone extinct, now with little complaint except from the most linguistically fastidious who insist the use in geometry remains the only meaning and all subsequent uses are mistakes.

Plutonium & Uranium

Plutonium (pronounced ploo-toh-nee-uhm)

A radioactive chemical element that is artificially derived from uranium, plutonium is a highly toxic metallic transuranic element.  It occurs in trace amounts in uranium ores and is produced in a nuclear reactor by neutron bombardment of uranium-238. The most stable and important isotope, plutonium-239, readily undergoes fission and is used as a reactor fuel in nuclear power stations and in nuclear weapons. Symbol: Pu; atomic no: 94; half-life (plutonium 239): 24,360 years; valency: 3, 4, 5, or 6; relative density (alpha modification): 19.84; melting point: 1184°F (640°C); boiling point: 5846°F (3230°C); specific gravity 19.84.  Its longest-lived isotope is Plutonium 244 with a half-life of 77 million years.

1941: The construct was Pluto (the (now dwarf-) planet), +–ium (the element ending suffix from the Latin -um (neuter singular morphological suffix) and based on Latin terms for metals such as ferrum (iron).  The –ium suffix (used most often to form adjectives) was applied as (1) a nominal suffix (2) a substantivisation of its neuter forms and (3) as an adjectival suffix.  It was associated with the formation of abstract nouns, sometimes denoting offices and groups, a linguistic practice which has long fallen from fashion.  In the New Latin, as the neuter singular morphological suffix, it was the standard suffix to append when forming names for chemical elements.  Plutonium was discovered at the University of California, Berkeley and so named because it follows the recently discovered neptunium in the periodic table and, at the time, Pluto followed Neptune in the Solar System.  The name plutonium earlier had been proposed for barium and was used sometimes in this sense early in the nineteenth century.

Pluto was from the Latin Plūtō, from the Ancient Greek Πλούτων (Ploútōn) (god of the underworld”).  In Greek mythology & Roman mythology, Pluto is remembered as the Greco-Roman god of the underworld but the ultimate origin was the Greek Ploutōn (god of wealth), from ploutos (wealth, riches (thought probably used originally in the sense of “overflowing”), from the primitive Indo-European root pleu- (to flow); the alternative Greek name Hades is also related to wealth because it is from beneath the earth that lie valuable metals & precious gems.  Although some have expressed doubt, the accepted history is it was then eleven year old Ms Venetia Burney (1918–2009) who suggested the name Pluto for the newly discovered (then) planet, aware of the procedure apparently because her uncle had earlier nominated Phobos and Deimos as names for the moons of Mars.  In 2006, the humorless International Astronomical Union (IAU) made its scandalous decision to declare, on highly technical grounds, that Pluto was not a planet but a mere dwarf and this inspired the American Dialect Society to coin the verb "to pluto" meaning "to demote or devalue something".

Uranium (pronounced yoo-rey-nee-uhm)

A white, lustrous, radioactive, metallic element, it has compounds used in photography and in coloring glass, the 235 isotope used in atomic and hydrogen bombs and as nuclear fuel in fission reactors.  A radioactive silvery-white metallic element of the actinide series, it occurs in several minerals including pitchblende, carnotite, and autunite.  Symbol: U; atomic no: 92; atomic wt: 238.0289; half-life of most stable isotope (uranium 238): 451 × 109 years; valency: 2-6; relative density: 18.95 (approx.); melting point: 2075°F (1135°C); boiling point: 7473°F (4134°C); specific gravity 18.95.

1789: The construct was Uranus + (the planet) the –ium.  The element was named (using the conventions of Modern Latin) because the discovery of the planet had recently been announced.  Uranus was from the Latin Ūranus, from the Ancient Greek Ορανός (Ouranós), from ορανός (ouranós) (sky, heaven).

Nuclear Weapons

Of the first three atomic bombs built in 1945, two used plutonium as fissile material while one used uranium.  Two of the many problems faced in the project were (1) production of uranium of the required purity was slow but a bomb of this type was (relatively) simple to produce and (2) plutonium was more abundant but the engineering to create such a bomb was intricate, the results uncertain.  Two designs were thus concurrently developed: a (relatively) simple trigger-type device and a more complex implosion-type.  Trinity, code-name for the world’s first detonation of a nuclear device (New Mexico, July 1945), was one of the latter, an implosion-type plutonium bomb.  It was chosen because this was a genuine test, there being no certainty it would work whereas the trigger-type uranium device, ultimately dropped on Hiroshima a month later, was never tested because the scientists and engineers had such confidence in its design.  After the war, it was assumed the somewhat inefficient trigger mechanism wouldn’t again be used but technical problems saw production temporarily resumed, these stop-gap A-Bombs remaining in service until 1951.

It’s no longer certain the uranium-based bomb used again Hiroshima in August 1945 remains a genuine one-off.  It’s certain that in the sixty-odd years since Trinity, every nuclear weapon except the Hiroshima device was plutonium-based but, beginning in 2006, the DPRK (the Democratic People's Republic of Korea (North Korea)) conducted six nuclear tests and, despite advances in monitoring and detection techniques, it’s not clear what material was used although the consensus is all were fission (A-Bombs) and not fusion (H-Bombs) devices.  The tests, by historic standards, were low-yield, suggesting uranium, but this could be misleading because even a failed test of can produce a nuclear blast called a fizzle (when a detonation fails grossly to meet its expected yield).  The DPRK's programme will have had the odd fizzle but then so has every nation at some stage of the process but by historic standards it must be judged a success.  It was hampered by sanctions and international opposition (Beijing and Moscow as unwilling as Western powers to help the hermit kingdom join the nuclear club) but achieved the  necessary technology transfer by swapping ballistic missile blueprints with Pakistan which had detonated it's first fission device in 1998 but lacked a robust delivery system to counter the "nuclear threat" from India which had tested as early as 1974.  That transaction was illustrative of one of the two concerns the West harbours about the DPRK bomb (1) some sort of accident (and that covers everything from an unplanned detonation in some unfortunate place to a missile launch which malfunctions and hits a populated area) and (2) nuclear proliferation which happens because the technology is used by Pyongyang in the barter economy as a trade for something desirable but not available because of sanctions or other trade restrictions.
