Undecennial

Undecennial (pronounced uhn-duh-seh-nee-uhl)

(1) Occurring or observed every eleventh year.

(2) As “undecennial magnetic period”, the Sun’s solar cycle.

1858: The construct was undec-, (from the Latin undecim, (eleven), the construct being unus (one) + decem (ten)) + -ennial.  The -ennial suffix was from the Latin -enniālis, the construct being annus (year (and figuratively “time, season, epoch”)) + -ium (the suffix used to form abstract nouns) + -ālis (suffixed to nouns or numerals creating adjectives of relationship).  It was a combining form denoting years.  The Latin undecentesimus was from ūndēcentum (ninety-nine; 99).  In Roman numerals, 99 was written as XCIX, the construct of which was XC (90: 100 minus 10) + IX (9: 10 minus 1) thus XC (90) plus IX (9) equals XCIX (99).  The fear of the number 11 is described as hendecaphobia.  The alternative adjective (and non-standard noun) is undecennary (once every eleven years) and the adjective in Portuguese is undecenal.  Undecennial & undecennary are adjectives and a (non-standard) noun; the noun plural is undecennials.

Centennial (every hundred years; commemoration of an event that happened a hundred years earlier) is the best known of the words suffixed with “-ennial” but there are fun constructs with meanings not immediately obvious including demisesquicentennial (75 years), the construct being demi- (half-of) +‎ sesqui- (one-and-a-half) +‎ centennial (of 100 years) and quadranscentennial (twenty-fifth anniversary (now often called “silver jubilee)), the construct being quad, from the Latin quadrans (quarter) + -ennium (a variant of annus) + -ālis (the “quad” thus a reference to the four 25 year quarter-centuries in a century).  Unfortunately, sexennial (pertaining to a period of six years; taking place once every six years) (the construct being sexennium (a period of six years) + -al) means just a “six year period or cycle” although in August 2024, in Boston Massachusetts there was the Sexennial: A Sex-Positive Variety Show.

In modern use, there’s also been some re-purposing.  The first use of “postmillennial” was to describe the world after the year 1000 and it has been used of things Pos-2000 but it was also adopted in the nineteenth century by certain Christian sects to describe the doctrine the Second Coming of Christ will take place after the millennium; the antonym was premillennial (pertaining to the belief the Second Coming will take place before the millennium.).  In the 21^st century, it’s used also of “Generation Z”, the one following the “Millennial Generation”.  Premillennial seems not to be used in this context (that would be the (Baby) Boomers).  The construct of the adjective perennial was the Latin perenn(is) (lasting through the whole year or for several years, perennial; continual, everlasting, perpetual”) + the English -al (the adjective-forming suffix imparting the meaning “of or pertaining to”.  It’s familiar from its use in botany where it describes plants active throughout the year, or having a life cycle of more than two growing seasons (and thus used sometimes in the sense of “appearing again each year; annual”) but is used also (sometime loosely) of waterways and such.  In figurative use, “perennial” is used widely (and loosely) of just about anything (art, music, politics et al) with the quality of or tending to “continuing without cessation or intermission for several years, or for an undetermined or infinite period; never-ending or never failing; perpetual, unceasing”.

Images from NASA’s Solar Dynamics Observatory highlight the appearance of the Sun at solar minimum (December 2019, left) versus solar maximum (May 2024, right).  These images are in the 171-angstrom wavelength of extreme ultraviolet light, which reveals the active regions on the Sun that are more common during solar maximum.

The Sun’s 11-year cycle was first detected in 1843 by German apothecary & amateur astronomer Heinrich Schwabe (1789–1875). Schwabe noticed a pattern in the number of sunspots that appeared on the Sun's surface over time.  In 1825 Herr Schwabe obtained his first telescope and between then and 1867 (on every day the skies were clear) he recorded the size & shape of sunspots and it was in 1838 he first suspected the phenomenon might be cyclical, his initial findings suggesting a ten-year cycle.  The discovery was wholly serendipitous because he wasn’t interested in sunspots (then thought random events) but was one of a number of astronomers searching for “Vulcan” a speculative planet in an orbit between Mercury which theories suggested should exist because its presence would account for the otherwise inexplicable peculiarities in Mercury's orbital path.  As a theory, the science was sound because earlier the same math had been used correctly to predict the existence of Neptune, based on calculation which determined the gravitational influence required to explain disturbances in the orbit of Uranus.  Over the decades, sightings of Vulcan had been reported but all quickly were discounted and the search continued until Albert Einstein’s (1879-1955) theory of general relativity (1915) was confirmed and Mercury's variation from the orbit predicted by Newtonian physics was understood to be a manifestation of the curvature of space-time induced by the mass of the Sun.

Because of Vulcan’s predicted proximity to the Sun, it would have been very difficult to observe with the telescopes of the nineteenth century, the only plausible method being to view it during its transit in front of the Sun.  The reason Herr Schwabe kept notebooks with almost daily sketches of the Sun and its spots was that he wanted to ensure he would never confuse a spot with the passing Vulcan and mush have be surprised when he noticed the suggesting of a cyclical pattern.  In 1843 he published his initial findings which indicated sunspot activity appeared to peak every ten-odd years and which his paper attracted little interest, it did inspire a Swiss professional astronomer to begin his own regular observations and these, combined with Herr Schwabe’s earlier drawings confirmed the sun’s undecennial pattern.  The use in 1858 of “undecennial” to describe the solar cycle seems to have been the first use of the word in English.

Visible light images from NASA’s Solar Dynamics Observatory highlight the appearance of the Sun at solar minimum (Dec 2019, left) versus solar maximum (May 2024, right). During solar minimum, often the Sun is "spotless".

The Sun's eleven-year cycle (the solar cycle) is driven almost wholly by changes in the body’s magnetic field dynamics.  The Sun’s magnetic field isn’t as stable as that of Earth which, although subject to some ongoing movement, retains its essential polarity for at least hundreds of thousands of years.  Deep within the Sun there exists a layer called the convection zone (where hot plasma rises, cools, and sinks) and these interactions, over time, cause the Sun’s magnetic field lines to twist and tangle.  Things are influenced also by differential rotation, the Sun rotating faster at its equator than at its poles (the equatorial regions taking some 25 days to complete a rotation, the polar regions around 35.  What this does is “stretches and wind up” the magnetic field lines, resulting in what astronomers describe as “a twisted, complex magnetic environment”.  All this combines to produce the “solar maximum & minimum”: Every eleven years the “twisted & tangled” magnetic field lines stretch to the point where suddenly they “snap”, creating a realigning process in which they are “straightened out”.  During solar maximum, the Sun has many sunspots (regions of intense magnetic activity), solar flares, and coronal mass ejections.  When the cycle resets to solar minimum, these activities reduce as the Sun's magnetic field temporarily stabilizes.  The other obvious effect of the undecennial magnetic period is the periodic polarity flip:  Every 11 years, the Sun’s magnetic poles reverse, north becoming south and vice-versa, something which happens on earth every few hundred-thousand years.

Quantum Tech Club's chart of the solar cycle: This cycle of low-high-low sun activity operates on a cycle of about eleven years though there are always variations, the length of each cycle not exact and the volume of activity also varies.  The previous Solar Cycle (24) was classified "not particularly active" and the current cycle (25) was predicted to be similar but it turned out to be more vibrant.  So, while the numbers bounce around, the undecennial pattern remains constant. 

For cultural reasons, an eleven year cycle sounds somehow strange to us and we’re unaccustomed to such things being associated with prime numbers although in entomology there are insects with no aversion to primes.  In entymology, there are insects with no fear of the number 17.  In the US, the so-called “periodical cicadas” (like those of the genus Magicicada) exist in a 17 year life cycle, something thought to confer a number of evolutionary advantages, all tied directly to the unique timing of their mass emergence: (1) The predator satiation strategy: The creatures emerge in massive numbers (in the billions), their sheer volume meaning it’s physically impossible for predators (both small mammals & birds) to eat enough of them to threaten the survival of the species. (2) Prime number cycles: Insects are presumed to be unaware of the nature of prime numbers but 17 is a prime number and there are also periodic cicadas with a 13 year cycle.  The 13 (Brood XIX) & 17-year (Brood X) periodic cicadas do sometimes emerge in the same season but, being prime numbers, it’s a rare event, the numbers' least common multiple (LCM) being 221 years; the last time the two cicadas emerged together was in 1868 and the next such even is thus expected in 2089.  The infrequency in overlap helps maintain the effectiveness of the predator avoidance strategies, the predators typically having shorter (2-year, 5-year etc) cycles which don’t synchronize with the cicadas' emergence, reducing chances a predator will evolve to specialize in feeding on periodical cicadas. (3) Avoidance of Climate Variability: By remaining underground for 17 years, historically, periodical cicadas avoided frequent climate changes or short-term ecological disasters like droughts or forest fires. The long underground nymph stage also allows them to feed consistently over many years and emerge when the environment is more favorable for reproduction.  Etymologists and biological statisticians are modelling scenarios under which various types of accelerated climate change are being studied to try to understand how the periodic cicadas (which evolved under “natural” climate change) may be affected. (4) Genetic Isolation: Historically, the unusually extended period between emergences has isolated different broods of cicadas, reducing interbreeding and promoting genetic diversity over time, helping to maintain healthy populations over multiple life-cycles.

A “year” as defined (one orbit of our world around the sun) on Earth is a standard measure and on this planet it makes complete sense but in other places (such as the Sun) it’s just an abstraction although we map “years” onto many remote places, vast distances best understood as expressed in “light years” although cosmologists for many purposes prefer the parsec (a unit of astronomical length, based on the distance from Earth at which a star would have a parallax of one second of arc which is equivalent to 206,265 times the distance from the earth to the sun or 3.26 light-years.  Its lineal equivalent is about 19.1 trillion miles (30.8 trillion km)).  It takes Pluto 248 Earth years to make its orbit of the Sun so that’s the length of one Plutoian year, meaning that between being discovered in 1930 and the humorous cosmic clerks at the International Astronomical Union (IAU) in 2006 voting 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), not even on year had there passed.

So it’s only on Earth one of our “years” is of direct relevance and we tend to measure anniversaries with the numbers we prefer (1, 2, 5, 10, 20, 25, 50. 100, 250, 500, 1000, 10,000 etc) (21 is a special case) but this meaning nothing to the physics of the Sun and even here there have been cultures in which some things have tended to the undecennial.  In India, the Kumbh Mela (or Kumbha Mela) is one of the great pilgrimage festivals in Hinduism (the pre-Covid gathering in 2019 said to be the largest (peaceful) assembly of people ever known) and although it is celebrated in what tends to be a twelve year cycle, because of the complexity and regional distribution of some celebrations, there have been times when things have happened at an eleven year interval.  Among the indigenous peoples of North America (notably the Hopi), there were also reports from anthropologists of ceremonial cycles based on natural and astronomical cycles that can approximate an eleven year pattern due to environmental changes or social cycles, although it doesn’t appear the intervals ever assumed a precise, recurrent eleven-year pattern.  Certain ceremonies were linked with observations of the sun (and other celestial bodies), aligning closely with solar maximums in some cases.

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 ἀναλογία (analogía), (ratio or proportion) the construct being ἀνά (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.

Indigo

Indigo (pronounced in-di-goh)

(1) A blue dye obtained from various plants, especially of the genus Indigofera, or manufactured synthetically.

(2) A descriptor of color indigo, widely defined commercially and ranging from a deep violet blue to a dark, greyish blue (sometimes as "indigo blue").

(3) In technical use, as indigo blue (also casually referred to as indigotin or indigo), a dark-blue, water-insoluble, crystalline powder (C₁₆H₁₀N₂O₂), having a bronze-like luster, the essential coloring principle of which is contained along with other substances in the dye indigo and which can be produced synthetically.

(4) Any of numerous hairy plants belonging to the genus Indigofera, of the legume family, having pinnate leaves and clusters of usually red or purple flowers (the best-known of the plants including Amorpha (false indigo), Baptisia (wild indigo), and Psorothamnus and Dalea (indigo bush)).

(5) In zoology, as the Eastern indigo snake, the common name for the Drymarchon couperi.

(6) In zoology, as the indigobird (or indigo bird), any of various African passerine birds of the family Viduidae.

(7) A (rarely used) female given name.

1550s: The spelling change from indico to indigo happened in the 1550s, used originally in the sense of the “blue powder obtained from certain plants and used as a dye”.  Indigo was from the Spanish indico and the Portuguese endego (the Dutch indigo exclusively was from Portuguese), all from the Latin indicum (indigo), from the Ancient Greek ἰνδικόν (indikón) (Indian blue dye (literally “Indian substance”)), a neuter of indikos (Indian), from the Indic Ἰνδία (Indía).  Indic is a subgroup of the Indo-Iranian branch of Indo-European languages that includes Sanskrit, Hindi, Urdu, Bengali, and many other languages of India, Pakistan, and Sri Lanka; Indo-Aryan.  It replaced the late thirteenth century Middle English ynde, from the thirteenth century Old French inde (indigo; blue, violet), again from the Latin indicum; the earlier name in Mediterranean languages was annil or anil.  In the magical-realist novel Sassafrass, Cypress & Indigo (1982) by African American feminist Ntozake Shange (1948–2018), the name of one protagonist is Indigo and it continues to be used as a given name for females.  Indigo is a noun & adjective and indigotic is an adjective; the noun plural is indigos or indigoes.

Sir Issac Newton, light and the "two prism experiment" 

As used to refer to “the color of indigo”, use dates from the 1620s and in 1704 Sir Isaac Newton (1642–1727) adopted indigo as the name for the darkest of the two blues on his spectrum of the visible colors of light.  Newton identified seven colors in the spectrum of light (red, orange, yellow, green, blue, indigo and violet) and although he was a great figure of science and the Enlightenment, he was also an alchemist and theologian who published notable works of Biblical scholarship, something which may account for the choice of seven, that number being of some significance in scripture.  By objective analysis, there are probably six colors in the spectrum, but Newton’s world view which attributed something mystical to the number demanded there be seven.  He decided in advance light was made of seven colors but his experimental method to vindicate this theory of differential refraction was sound.  The orthodox view of the time suggested a prism acted on any incident light to add colour; Newton wished to prove what was really happening was a process of separation refraction.  For this, he used two prisms.  The first produced the full spectrum of colors and from this Newton isolated narrow beams of light of a single colour, directing them at the second prism, finding that for all colors, there was no further change as the beam passed through the second prism: “When any one sort of Rays hath been well parted from those of other kinds, it hath afterwards obstinately retained its colour, not with standing my utmost endeavours to change it.”

Lindsay Lohan shopping at Indigo Seas, North Robertson Boulevard, Los Angeles, February 2009.  Most fashion houses would regard her dress’s blue as “too blue” to be within the indigo range but to illustrate how far (in commercial use) indigo can travel from blue, some would call this "Spanish indigo" (Hex: #003C92; RGB: 0, 60, 148).

Although some use extends even to grey, generally, indigo is a range of bluish-purples between blue and violet in the color wheel and such is the reverence for Newton it’s considered still one of the seven spectral colors (indigo’s hex code is #4B0082),  In this, although it may visually be dubious, indigo has fared better than the unfortunate Pluto, the International Astronomical Union (IAU) voting in 2006 to re-classify Pluto as a dwarf planet on the basis the icy orb failed to meet a set of criteria which the IAU claimed had been accepted for decades.  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, not affected by romantic tales, have refused to restore Pluto to planethood, leaving it desolate, lonely and cold; it's the solar system’s emo.  Indigo place on the spectrum seems however secure and according to Canva (the internet’s authority on colors), it’s the color of devotion, wisdom, justice, and higher knowledge; tied to intuition and what is not seen; it is also considered spiritual.  More prosaically, Canva list indigo as hexadecimal #4b0082, with RGB values of Red: 29.4, Green: 0, Blue: 51 and CMYK values of Cyan: 0.42, Magenta: 1, Yellow: 0, Black (K):0.49.  The decimal value is 4915330.  It has a hue angle of 274.6 degrees, a saturation of 100% and a lightness of 25.5%. #4b0082 color hex could be obtained by blending #9600ff with #000005. Closest websafe color is: #330099.

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 Οὐρανός (Ouranós), from οὐρανός (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.

Twilight

Twilight (pronounced twahy-lahyt)

(1) The soft, diffused light from the sky when the sun is below the horizon, either from daybreak to sunrise or, more commonly, from sunset to nightfall.

(2) The period in the morning or, more commonly, in the evening during which this light prevails.

(3) A terminal period, especially after full development, success, etc.

(4) A state of uncertainty, vagueness, or gloom.

(5) Of or relating to, or resembling twilight; dim; obscure:

(6) Appearing or flying at twilight; crepuscular.

(7) The period of time during which the sun is a specified angular distance below the horizon (6°, 12° and 18° for civil twilight, nautical twilight, and astronomical twilight respectively)

1375-1425: From the Middle English twyelyghte (twilight) from the Old English twēonelēoht (twilight), the construct being twi (double, half) +‎ light, literally “second light, half-light”.  Light was from the Middle English light, liht & leoht, from the Old English lēoht, from the Proto-West Germanic leuht, from the Proto-Germanic leuhtą, from the primitive Indo-European lewktom, from the root lewk- (light).  It was cognate with the Scots licht (light), the West Frisian ljocht (light), the Dutch licht (light), the Low German licht (light) and the German Licht (light).  It was related also to the Swedish ljus (light), the Icelandic ljós (light), the Latin lūx (light), the Russian луч (luč) (beam of light), the Armenian լույս (luys) (light), the Ancient Greek λευκός (leukós) (white) and the Persian رُخش‎ (roxš).  It was cognate with the Scots twa licht, twylicht & twielicht (twilight), the Low German twilecht & twelecht (twilight), the Dutch tweelicht (twilight, dusk) and the German zwielicht (twilight, dusk).  The exact connotation of twi- in this word remains unclear but most etymologists link it to "half" light, rather than the fact that twilight occurs twice a day.  In that twilight may be compared with the Sanskrit samdhya (twilight, literally "a holding together, junction") and the Middle High German zwischerliecht (literally "tweenlight").

The meaning "light from the sky when the sun is below the horizon at morning and evening" dates from the late fourteenth century, used often in the form "twilighting").  It was used originally (and most commonly) in English with reference to evening twilight but occasionally, beginning in the fifteenth century, referred also to the light of dawn.  The figurative extension dates from circa 1600.  The "twilight zone" is from 1901 (in a literal sense of the part of the sky lit by twilight), the use extended after from 1909 to refer to topics or cases where authority or behavior is unclear, the origin of that probably the 1909 novel In the Twilight Zone by Roger Carey Craven, the reference is to the mulatto heritage of one character, the idea of what used to be called the "half-breed", one who might be equally be claimed or disowned by either race.  The name was re-used in 2016 by Nona Fernández (b1971) (translated into English by Natasha Wimmer (b 1973)) in a novel about Chile under the dictatorship (1973-1990) of General Augusto Pinochet (1915–2006).  The US TV series of that name is from 1959.  The connotation of “twi” in this context is uncertain with most etymologists concluding it appears to refer to "half" light, rather than the state of twilight which occurs twice a day although in Sanskrit samdhya (twilight) was literally "a holding together” or “junction”, a formation known also in the Middle High German zwischerliecht, literally "tweenlight".  Twilight today is most commonly used with its original meaning of the evening light but from the mid-fifteenth century to the mid-twentieth, it was used also to refer to the morning twilight.  The figurative extension is first recorded circa 1600.

Götterdämmerung

Richard Wagner (1865) by August Friedrich Pecht (1814–1903), oil on canvas, Metropolitan Museum of Art, Ney York.

Götterdämmerung (Twilight of the Gods), is the fourth and final part of Richard Wagner's (1813-1883) Der Ring des Nibelungen (The Ring of the Nibelung, usually known as The Ring or Ring Cycle).  Lasting some fifteen hours and usually presented over several days, its debut performance was at the Bayreuth Festival on 17 August 1876.

A great set piece drama and the grandest moment in Opera, the Ring Cycle is about the destruction of the gods and in a final battle with evil powers and although based on an old Norse myth, a dubious translation of the Old Icelandic Ragnarǫk (fate of the gods) meant it entered Modern German as Ragnarökkr (twilight of the gods).  In the Norse, the story was of "ancestral voices prophesying war" between mortals and the gods, a conflict ending in flames and flood but leading finally to the renewal of the world.  Wagner's work differs much from the Old Norse.

Part 1: Das Rheingold (Rhinegold)

The Rig Cycle begins with the dwarf Alberich seizing the gold of the Rhinemaidens. Alberich denounces love to gain possession of the magic ring which gives its wearer ultimate power; the ring is the world’s most desired object.  Rhinegold is the story of the gods; one learns of the suffering of Wotan and the problems the gods have in repaying Fafner and Fasolt, the giants who built Valhalla.

Part 2: Die Walkure (The Valkyries)

Brunnhilde and her father Wotan struggle with their pride to decide the ultimate destiny of mortals, the Valkyries being about the deep, tortured relationship between gods and mortals.  The gods also war with each-other but nobleness, especially in love, prevails over the oaths and the divine promises of the gods. Siegmund, the mortal hero, dies because his father, Wotan, is obliged to obey his wife, Fricka.

Part 3: Siegfried

This is the story of the hero, Siegfried, how he grows to manhood, how he discovers love and loss.  Raised by the Nibelung Mime, Siegfried is young, innocent and fearless and with help from a mysterious wanderer (Wotan in disguise), Siegfried finds the pieces of his father's sword.  Notung reforges the blade and Siegfried kills the dragon Fafner who guards the hoard of Nibelung gold stolen from the Rhinemaidens, taking possession of Alberich's cursed ring.  Siegfried is then drawn to follow a birdsong to find the sleeping Brunnhilde whom fate has destined him to awaken and fall in love with.  Waking her, Siegfried gives the ring to Brunnhilde to symbolize his oath of undying love and fidelity.

Part 4: Götterdämmerung (Twilight of the Gods)

Under an ambiance impending doom, all face the consequences of their choices; the Nibelung Alberich's curse upon the Ring proving prophetic for whoever holds the ring is ultimately destroyed.  Although Wotan's disempowerment was, in part three, foreshadowed by Siegfried breaking his spear, the doomed fate of the gods is sealed when Alberich's evil son, Hagen dupes and cruelly murders the brave mortal hero Siegfried.  Devastated, Brünnhilde has a huge funeral pyre built by the river, takes the ring and tells the Rhinemaidens to claim it from her ashes.  Brünnhilde then mounts her horse and rides into the flames.  As she burns, the Rhine overflows, quenching the fire and the Rhinemaidens swim in to claim the ring.  Hagen tries to stop them but they drag him to his death in the depths.  As they celebrate the return of the ring and its gold to the river, a red glow fills the sky for Valhalla, the last resting place of the gods is ablaze and the gods are consumed by the flames.

Stunt

Stunt (pronounced stuhnt)

(1) To stop, slow down, or hinder the growth or development of; dwarf; arrested development.

(2) In botanical pathology, a disease of plants, characterized by a dwarfing or stunting of the plant.

(3) A performance displaying a person's skill or dexterity, as in athletics; feat.

(4) Any remarkable feat performed chiefly to attract attention.

1575-1585: From the dialectal stunt (stubborn, dwarfed), from the Middle English stont & stunt (short, brief), from the Old English stunt (stupid, foolish, simple (as in stuntspræc "foolish talk")), from the Proto-Germanic stuntaz (short, compact, stupid, dull).  It was cognate with the Middle High German stunz (short, blunt, stumpy) from the Proto-Germanic stuntaz (short, truncated), and the Old Norse stuttr (short in stature, dwarfed).  It was related also to the Old English styntan (to make dull, stupefy, become dull, repress).

The origin of the noun use of stunt is obscure although all agree it’s of US origin circa 1878 and some sources suggest it was originally college sports slang though without evidence of youthful coinage.  Links have been suggested to the Middle Low German stunt (a shoulder grip with which you throw someone on their back), a variant of the colloquial stump (dare, challenge) (1871), the German stunde (literally "hour") and the Middle English stunt (foolish; stupid) but no documentary evidence exists.  The noun in this sense certainly caught on, applied particularly to aerobatic display by aircraft and gained a new life when Youtube and its imitators provided a platform.  Stunt historically was a verb, the familiar noun a later form, the earlier noun was stuntedness, the adverb is stuntingly and the adjectives stunty & stunted.

In Film & television production, the terms "stunt double" & "body double" are sometimes used interchangeably but by convention they describe different roles.  The classic stunt double is engaged to perform those parts of the script which call upon an actor to do something especially physically demanding which typically requires special skills and may involve some risk; there there has been an injury toll among stunt doubles with deaths are not unknown.  The term body double is usually used of those engaged (1) to appear in scenes in which an actor wishes not to appear (such as those involving nudity) or (2) to permit something to be filmed which would otherwise defy the laws of nature (such as an actor having a conversation with themselves).  Advances in technology mean the laws of nature now are little obstacle to the impossible being depicted but many actors still have "no-nudity" clauses in contracts although the profession is now much concerned the combination of digital editing and artificial intelligence (AI) will soon render even all this obsolete.  Actually, at the technical level, flesh & blood actors might soon be (or already are) obsolete but their hope is audiences will continue to demand real people playing the parts.  Time will tell.  In her recent Netflix projects, Lindsay Lohan used a body double in Irish Wish (now slated for release in early 2024) but in Falling for Christmas (2022) needed a stunt double for the skiing scenes, the role taken by Rian Zetzer (b 1996), a Salt Lake City-based former competitive mogul skier and sponsored free-skier.

The Cunning Stunts (1977-1982)

Feminist theatre, although with identifiable roots in the Weimar Republic (Germany: 1918-1933), came to be recognized, theorized, and practiced during the 1970s in the wake of second-wave feminism.  Although it encompassed diverse theatrical work, it’s always been most associated with the overtly political, a movement motivated by the recognition of and resistance to women’s marginalization within social and cultural systems that reinforce male privilege and dominance.  In this it acted out a resistance to mainstream, male-dominated theatre culture and revived long-neglected works and performances by women from the dramatic texts of Hrotsvitha (circa 935–973), plays by Restoration playwrights such as Aphra Behn (1640–1689), Mary Pix (1666–1709) & Susanna Centlivre (circa 1669-1723) and dramas by the Edwardian activists most interested in suffrage, Elizabeth Baker (1876–1962), Cicely Mary Hamilton (1872–1952), Elizabeth Robins (1862–1952), & Katherine Githa Sowerby (1876–1970).

What emerged from the second wave came largely to be defined by three types of feminism: bourgeois/liberal, radical/cultural & socialist/materialist.  Critics treated the three in a hierarchical construct of respectability, bourgeois/liberal feminism treated as politically the weakest given it neither endorsed radical feminism’s desire to overthrow patriarchy in favor of women’s social, cultural and sexual empowerment, nor advocated the radical transformation of society’s economic, political and social structures as socialist/materialist feminism did.  Each dynamic had its aesthetic counterpart: bourgeois/liberal feminism remained attached to conventional realistic forms, but sought a greater role for women within the confines of traditional dramatic writing; radical/cultural feminism, heavily influenced by French theorists, explored a women’s language; socialist/materialist feminism found its aesthetic in the Brechtian legacies of presentational forms, techniques and performance registers.

In this milieu, the debut in London in 1977 of the feminist performance collective Cunning Stunts was unexpected.  Neither overtly nor even identifiably political, they were something of a reaction to feminist theatre itself, the members noting feminist “alternative theatre” had become elitist and they wanted a more accessible and spontaneous performer’s platform rather than a writer’s or director’s theatre, one which not only displayed the absurdity of male behavior but presented women being funny, flouting the prevailing glamorous image of women as entertainers.  The shows were musical, visual, highly energetic and existed mostly to offer fun rather than any political or cultural critique although later productions, such as Opera, said to use their “…versions of archetypal symbols and mythological characters drawn from astrology, matriarchal societies… to express the experiences of living as wimin (sic) in a male strangulated world” did suggest other agendas remained of interest.

Suffering the internal conflicts perhaps endemic to collectives, the Cunning Stunts dissolved in 1982, having seemingly worked their concept dry.  In the UK, much alternative theatre didn’t survive the 1980s, the Thatcher government dismantling many of the often left-wing local authorities which had provided a substantial proportion of the funding.
