Chicane

Chicane (pronounced shi-keyn or chi-keyn)

(1) In bridge, a hand without trumps.

(2) In motor sport, one bend or a short section of sharp bends formed either by the design of the track or by barriers placed on the circuit.

(3) To quibble over; cavil at (now rare, probably extinct).

(4) A less common word for chicanery (deception; trickery); to use chicanery, tricks or subterfuge (rare).

1665-1675: A borrowing from the French chicane, from chicaner (to quibble (of obscure origin)), from the Middle French chicaner, from the Middle Low German schicken & schikken (to arrange), ultimately from the Proto-Germanic skikkijaną, origin of modern French chic.  The word has been used in English in various senses, including as an "act of chicanery” (the art of gaining advantage by using evasions or cheating tricks) from the 1670s.  The now most familiar sense, "obstacles on a roadway" didn’t emerge until 1955 (quickly spreading to motor-racing circuits) although it had been a technical term in bridge design since the 1880s.  All the English forms are from the archaic verb chicane (to trick), first noted in the 1660s, from the sixteenth century French chicane (trickery) from chicaner (to pettifog, to quibble).  Chicane, chicanery & chicaner are nouns, chicanerous is an adjective and chicaned & chicaning are verbs; the noun plural is chicanes.

Chicanery & low skullduggery: The film Mean Girls (2004) was based on Rosalind Wiseman's (b 1969) book Queen Bees and Wannabes: Helping Your Daughter Survive Cliques, Gossip, Boyfriends, and Other Realities of Adolescence (2002) which explored the interaction of the shifting social cliques formed by school girls.

Of the chicanery of the FIA

The FIA (Fédération Internationale de l'Automobile (International Automobile Federation)) has since 1904 been involved in the organisation and regulation of motor-racing.  The FIA used to be mostly harmless but in recent decades has degenerated into about the most dopey regulatory body in sport, making the men of World Rugby’s (the old International Rugby Board (IRB)) standing Laws Committee look like chaps of rare skill and talent.  For a long time the FIA have approved not at all of any interesting form of motor-racing, their response always to make things slower and more processional, a curious approach in a sport about speed.  Although most obsessed with publishing volumes of complex regulations which require the employment of FIA officials to administer, the FIA also has an almost fetishistic relationship with chicanes.  A chicane is essentially an obstruction which requires a racing car to slow to negotiate.  While curves, climbs and corners have always been part of just about any form of motor-racing, the FIA seems never convinced there are enough.  It’s suspected if the FIA had their way, there would be no straights on motor-racing circuits, just corners.

Le Mans, before and after.

Mulsanne Straight (Ligne Droite des Hunaudières in French) at Circuit de la Sarthe where the annual Twenty-Four Hours of Le Mans (24 Heures du Mans) is run was once 3.7 miles (6 km) in length.  It was one of the sport’s great institutions, the speeds attained a benchmark of progress in engineering and aerodynamics.

These achievements impressed most but not the FIA which, for reasons of their own, decided to sabotage things, initially by reducing the maximum engine capacity in the premier class, firstly from seven litres to five and later to three.  When this didn’t prove sufficient to nobble the engineers, they insisted two chicanes be added to Mulsanne Straight.  They were installed in 1990 and proved effective, no car since has, in the race, come within 20 mph (32 km/h) of the marks set in the late 1980s and speeds in excess of 200 mph (320 km/h) are now rare.  The FIA has emasculated other circuits too; in 1987 a chicane (the Chase) imposed upon Conrod Straight at Mount Panorama, Bathurst in Australia.  Quite why the FIA remains involved in motor-racing isn’t clear when it’s apparent they'd be better suited to the administration of something like competitive basket-weaving.

Recursive

Recursive (pronounced ri-kur-siv)

(1) Pertaining to or using a rule or procedure that can be applied repeatedly; periodically recurring.

(2) Drawing upon itself, referring back.

(3) In mathematics, of an expression, each term of which is determined by applying a formula to preceding terms

(4) In computing, of a program or function that calls itself (often in the form of an endlessly repeating script).

(5) In computing theory, of a function which can be computed by a theoretical model of a computer, in a finite amount of time.

(6) In computing, a set whose characteristic function is recursive.

(7) In linguistics (as recursive acronym), an acronym in which the first letter of the first word represented by the acronym is the acronym itself.

1790: From the stem of Latin recursus, perfect passive participle of recurrō (I run or hasten back; I return, revert, recur), the construct being recurs(ion) + -ive.  The –ive suffix is from the Anglo-Norman -if (feminine -ive), from the Latin -ivus; the related forms are the adverb recursively and the noun recursiveness.  Until the fourteenth century, all Middle English loanwords from the Anglo-Norman ended in -if (actif, natif, sensitif, pensif et al) and, under the influence of literary Neolatin, both languages introduced the form -ive.  Those forms that have not been replaced were subsequently changed to end in -y (hasty, from hastif, jolly, from jolif etc).  Like the Latin suffix -io (genitive -ionis), the Latin suffix -ivus is appended to the perfect passive participle to form an adjective of action.  The use in mathematics dates from 1934.  Recursive is an adjective inflected form of recursion which is a noun.  Recursive is an adjective, recursivity & recursiveness are nouns and recursively is an adverb; the noun plural is recursivities.  

The recursive acronym

Although recursive acronyms had existed before, appearing in fiction as early as 1968, the term first gained wider attention when discussed in US physicist’s Douglas Hofstadter's (b 1945) 1979 book Gödel, Escher, Bach: an Eternal Golden Braid.  Recursive acronyms typically form backwardly: either an existing ordinary acronym is given a new explanation or, a name is turned into an acronym by giving the letters an explanation of what they stand for, in each case with the first letter standing recursively for the whole acronym.

Not an easy txt to absorb for those without a helpful background, even the title of Gödel, Escher, Bach is at first glance misleading because it’s not a look at the relationships between art, music and mathematics but instead an exploration of the abstract structures which exist within each.  These Hofstadter called “strange loops”, the logician Kurt Friedrich Gödel (1906–1978) having demonstrated their existence in any mathematical system of sufficient complexity.

Relativity, lithograph (1953) by MC Escher (1898–1972).

Hofstadter pursued these structural imperatives in music and art, suggesting it’s strange loops which creates consciousness, the connections and chemicals in the human brain creating the fundamental base of the framework on which are hung ideas, feelings, hopes and desires, all of which manifest further up the framework.  Consciousness became possible (and there are those who suggested inevitable) because the hierarchy clinging to the framework can twist back on itself: higher and lower levels influencing and interacting so the lower which once must have entirely determined the upper is also changed, ideas and feelings having an actual physical impact, this tangling of hierarchies being our sense of self.

Others, tentatively had posed similar questions.  Eugene Charniak’s (b 1946) strangely neglected PhD thesis (MIT, 1974) at least hinted it might be fruitful to explore the relationship of knowledge and inference to natural language understanding and Gödel, Escher, Bach is a playful, clever, if sometimes obviously contrived way to offer one explanation of how cognition emerges from a mechanistic structure which is reflected in work that cognition can allow to be created.  As a technical point, remarkably for a piece so dependent on the nuances and interplay of language, Gödel, Escher, Bach has been translated.
