1615–1625: The original use was to describe insects, apparently as a variant of the earlier bugge (beetle), thought to be an alteration of the Middle English budde, from the Old English -budda (beetle) but etymologists are divided on whether the phrase “bug off” (please leave) is related to the undesired presence of insects or was of a distinct origin.  Bug, bugging & debug are nouns & verbs, bugged is a verb & adjective and buggy is a noun & adjective; the noun plural is bugs.  Although “unbug” makes structural sense (ie remove a bug, as opposed to the sense of “debug”), it doesn’t exist whereas forms such as the adjectives unbugged (not bugged) and unbuggable (not able to be bugged) are regarded as standard.

The array of compound forms meaning “someone obsessed with an idea, hobby etc) produced things like “shutterbug” (amateur photographer) & firebug (arsonist) seems first to have emerged in the mid nineteenth century.  The development of this into “a craze or obsession” is thought rapidly to have accelerated in the years just before World War I (1914-1918), again based on the notion of “bitten by the bug” or “caught the bug”, thus the idea of being infected with an unusual enthusiasm for something.  The use to mean a demon, evil spirit, spectre or hobgoblin was first recorded in the mid-fourteenth century and was a clipping of the Middle English bugge (scarecrow, demon, hobgoblin) or uncertain origin although it may have come from the Middle Welsh bwg (ghost; goblin (and linked to the Welsh bwgwl (threat (and earlier “fear”) and the Middle Irish bocanách (supernatural being).  There’s also speculation it may have come from the scary tales told to children which included the idea of a bugge (beetle) at a gigantic scale.  That would have been a fearsome sight and the idea remains fruitful to this day for artists and film-makers needing something frightening in the horror or SF (science fiction) genre.  The use in this sense is long obsolete although the related forms bugbear and bugaboo survive.  Dating from the 1570s, a bugbear was in folklore a kind of “large goblin”, used to inspire fear in children (both as a literary device & for purposes of parental control) and for adults it soon came to mean “a source of dread, resentment or irritation; in modern use it's an “ongoing problem”, a recurring obstacle or adversity or one’s pet peeve.  The obsolete form bugg dates from circa 1620s and was a reference to the troublesome bedbug, the construct a conflation of the middle English bugge (scarecrow, hobgoblin) and the Middle English budde (beetle).  The colloquial sense of “a microbe or germ” dates from 1919, the emergence linked to the misleadingly-named “Spanish flu” pandemic.

Like the rest of us, even scientists, entomologists and zoologists generally probably say “bug” in general conversation, whether about the insects or the viruses and such which cause disease but in writing academic papers they’ll take care to be more precise.  Because to most of us “bugs” can be any of the small, creepy pests which intrude on our lives (some of which are actually helpful in that quietly and unobtrusively they dispose of the really annoying bugs which bite us), the word is casually and interchangeably applied to bees, ants, bees, millipedes, beetles, spiders and anything else resembling an insect.  That use may be reinforced by the idea of the thing “bugging” us by their very presence.  To the professionals however, insects are those organisms in the classification Insecta, a very large class of animals, the members of which have a three-part body, six legs and (usually) two pairs of wings whereas a bug is a member of the order Hemiptera (which in the taxonomic system is within the Insecta class) and includes cicadas, aphids and stink bugs; to emphasize the point, scientists often speak of those in the order Hemiptera as “true bugs”.  The true bugs are those insects with mouthparts adapted for piercing and sucking, contained usually in a beak-shaped structure, a vision agonizingly familiar to anyone who has suffered the company of bedbugs.  That’s why lice are bugs and cockroaches are not but the latter will continue to be called bugs, often with some preceding expletive.

9 September 1947: The engineer's note (with physical evidence) of electronic computing's "first bug".

In computing, where the term “bug” came to be used to describe “glitches, crashes” and such, it has evolved to apply almost exclusively to software issues and even if events are caused by hardware flaws, unless it’s something obvious (small explosions, flame & smoke etc) most users probably assume a fault in some software layer.  The very first documented bug however was an interaction recorded on 9 September 1947 between the natural world and hardware, an engineer’s examination of an early (large) computer revealing an insect had sacrificially landed on one of the circuits, shorting it out and shutting-down the machine.  As proof, the unfortunate moth was taped to the report.  On a larger scale (zoologically rather than the hardware), the problem of small rodents such as mice entering the internals of printers, there to die from various causes (impact injuries, starvation, heat et al) remains not uncommon, resulting sometimes in mechanical damage, sometimes just the implications of decaying flesh.

The idea of a bug as a “defect, flaw, fault or glitch” in a mechanical or electrical device was first recorded in the late 1800s as engineer’s slang, the assumption being they wished to convey the idea of “a small fault” (and thus easily fixed, as opposed to some fundamental mistake which would necessitate a re-design).  Some sources suggest the origin lies with Thomas Edison (1847-1931) who is reported as describing the consequences of an insect “getting into the works”.  Programmers deploy an array of adjectives to "bug" (major, minor, serious, critical & non-critical et al) although between themselves (and certainly when disparaging of the code of others) the most commonly heard phrase is probably “stupid bug”.  The “debugging” (also as de-bugging) process is something with a wide definition but in general it refers to any action or set of actions taken to remove errors.  The name of the debug.exe (originally debug.com) program included with a number of (almost all 16 & 32-bit) operating systems was a little misleading because in addition to fixing things, it could be used for other purposes and is fondly remembered by those who wrote Q&D (quick & dirty) work-arounds which, written in assembler, ran very fast.  The verb debug was first used in 1945 in the sense of “remove the faults from a machine” and by 1964 it appeared in field service manuals documenting the steps to be taken to “remove a concealed microphone”.  Although the origin of the use of “bug” in computing (probably the now most commonly used context) can be traced to 1947, the term wasn’t widely used beyond universities, industry and government sites before the 1960s when the public first began to interact at scale with the implications (including the bugs) of those institutions using computerized processes.  Software (or any machinery) badly afflicted by bugs can be called “buggy”, a re-purposing of the use of an adjective dating from 1714 meaning “a place infested with bugs”.

Some bugs gained notoriety.  In the late 1990s, it wasn’t uncommon for the press to refer to the potential problems of computer code using a two-numeral syntax for years as the “Y2K bug” which was an indication of how wide was the vista of the common understanding of "bug" and one quite reasonable because that was how the consequences would be understood.  A massive testing & rectification effort was undertaken by the industry (and corporations, induced by legislation and the fear of litigation) and with the coming of 1 January 2000 almost nothing strange happened and that may also have been the case had nothing been done but, on the basis of the precautionary principle, it was the right approach.  Of course switching protocols to use four-numeral years did nothing about the Y10K bug but a (possible) problem 8000 years hence would have been of little interest to politicians or corporate boards.  Actually, YxK bugs will re-occur (with decreasing frequency) whenever a digit needs to be added.  The obvious solution is trailing zeros although if one thinks in terms of infinity, it may be that, in the narrow technical sense, such a solution would just create an additional problem although perhaps one of no practical significance.  Because of the way programmers exploit the way computers work, there have since the 1950s been other date (“time” to a computer) related “bugs” and management of these and the minor problems caused has been handled well.  Within the industry the feeling is things like the “year 2029 problem” and “year 2038 problem” will, for most of the planet, be similarly uneventful.

The DOSShell, introduced with PC-DOS 4.0; this was as graphical as DOS got.  The DOSShell was bug-free.

Bugs can also become quirky industry footnotes.  As late as 1987, IBM had intended to release the update of PC-DOS 3.3 as version 3.4, reflecting the corporation’s roadmap of DOS as something of an evolutionary dead-end, doomed ultimately to end up in washing machine controllers and such while the consumer and corporate market would shift to OS/2, the new operating system which offered pre-emptive multi-tasking and access to bigger storage and memory addressing.  However, at that point, both DOS & OS/2 were being co-developed by IBM & Microsoft and agreement was reached to release a version 4 of DOS.  DOS 4 also included a way of accessing larger storage space (through a work-around with a program called share.exe) and more memory (in a way less elegant than the OS/2 approach but it did work, albeit more slowly), both things of great interest to Microsoft because they would increase the appeal of its upcoming Windows 3.0, a graphical shell which ran on top of DOS; unlike OS/2, Windows was exclusive to Microsoft and so was the revenue stream.  Unfortunately, it transpired the memory tricks used by PC-DOS 4.0 were “buggy” when used with some non-IBM hardware and the OS gained a bad reputation from which it would never recover.  By the time the code was fixed, Microsoft was ready to release its own version as MS-DOS 4.0 but, noting all the bad publicity, after a minor updates and some cosmetic revisions, the mainstream release was MS-DOS 4.01.  In the code of the earlier bug-afflicted bits, there is apparently no difference between MS-DOS 4.01 the few existing copies of MS-DOS 4.0.

In idiomatic and other uses, bug has a long history.  By the early twentieth century “bugs” meant “mad; crazy" and by then “bug juice” had been in use for some thirty years, meaning both “propensity of the use of alcoholic drink to induce bad behaviour” and “bad whiskey” (in the sense of a product being of such dubious quality it was effectively a poison).  A slang dictionary from 1811 listed “bug-hunter” as “an upholsterer”, an allusion to the fondness bugs and other small creatures show for sheltering in the dark, concealed parts of furniture.  As early as the 1560s, a “bug-word” was a word or phrase which “irritated or vexed”.  The idea of “bug-eyed” was in use by the early 1870s and that’s thought either to be a humorous mispronunciation of bulge or (as is thought more likely) an allusion to the prominent, protruding eyes of creatures like frogs, the idea being they sat on the body like “a pair of bugs”.  The look became so common in the movies featuring aliens from space that by the early 1950s the acronym BEM (bug-eyed monster) had become part of industry slang.  The correct term for the medical condition of "bulging eyes" is exophthalmos.

To “bug someone” in the sense of “to annoy or irritate” seems not to have been recorded until 1949 and while some suggest the origin of that was in swing music slang, it remains obscure.  The now rare use of “bug off” to mean “to scram, to skedaddle” is documented since 1956 and is of uncertain origin but may be linked to the Korean War (1950-1953) era US Army slang meaning “stage a precipitous retreat”, first used during a military reversal.  The ultimate source was likely the UK, Australian & New Zealand slang “bugger off” (please leave).  The “doodle-bug” was first described in 1865 and was Southern US dialect for a type of beetle.  In 1944, the popular slang for the German Vergeltungswaffen eins (the V-1 (reprisal weapon 1) which was the first cruise missile) was “flying bomb” or “buzz bomb”) but the Royal Air Force (RAF) pilots preferred “doodle-bug”.

The ultimate door-stop for aircraft hangers: Bond Bug 700.

The popularity of three wheeler cars in the UK during the post-war years was a product of cost breakdown.  They were taxed at a much lower rate than conventional four-wheel vehicles, were small and thus economical and could be operated by anyone with only a motorcycle licence.  Most were actually genuine four-seaters and thus an attractive alternative for families and, being purely utilitarian, there were few attempts to introduce elements of style.  The Bond Bug (1970-1974) was an exception in that it was designed to appeal to the youth market with a sporty-looking two-seater using the then popular “wedge-styling” and in its most powerful form it could touch 80 mph (130 km/h), faster than any other three wheeler available.  However, the UK in 1973 introduced a value-added tax (VAT) and this removed many of the financial advantages the three-wheelers.  In an era of rising prosperity, the appeal of the compromise waned and coupled with some problems in the early productions runs, in 1974, after some 2¼ thousand Bugs had been built, the zany little machine was dropped; not even the oil crisis of the time (which had doomed a good number of bigger, thirstier cars) could save it.  Even in its best years it was never all that successful, essentially because it was really a novelty and there were “real” cars available for less money.  Still, the survivors have a following in their niche at the lower end of the collector market.

The business of spying is said to be the “second oldest profession” and even if not literally true, few doubt the synergistic callings of espionage and war are among man’s earliest and most enduring endeavors.  Although the use of “bug” to mean “equip with a concealed microphone” seems not to have been in use until 1946, bugging devices probably go back thousands of years (in a low-tech sort of way) and those known to have been used in Tudor-era England (1485-1603) are representative of the way available stuff was adapted, the most popular being tubular structures which, if pressed against a thin wall (or preferably a door’s keyhole) enabled one to listen to what was being discussed in a closed room.  Bugging began to assume its modern form when messages began to be transmitted over copper wires which could stretch for thousands of miles and the early term for a “phone bug” was “phone tap”, based upon the idea of “tapping into” the line as one might a water pipe.  Bugs (the name picked-up because many of the early devices were small, black and “bug-like”), whether as concealed microphones or phone taps, swiftly became part of the espionage inventory in diplomacy, commerce and crime and as technology evolved, so did the bugging techniques.

Henry Cabot Lodge Jr (1902–1985), US Ambassador to the UN (United Nations) at a May 1960 session of the Security Council, using the Great Seal bug to illustrate the extent of Soviet bugging.  The context was a tu quoque squabble between the Cold War protagonists, following Soviet revelations about the flight-paths of the American's U2 spy planes.  Lodge would be Richard Nixon’s (1913-1994; US president 1969-1974) running mate in that year's presidential election.     

A classic bug of High Cold War was the Great Seal bug, (known to the security services as the thing), a Soviet designed and built concealed listening device which was so effective because it used passive transmission protocols for its audio signal, thereby rendering it invisible to conventional “bug-detection” techniques.  The bug was concealed inside large, carved wooden rendition of the US Great Seal which, in 1945, the Kremlin presented as a “gift of friendship” to the US Ambassador to the USSR Averell Harriman (1891-1986); in a nice touch, it was a group of Russian school children who handed over the carving.  Sitting in the ambassador’s Moscow office for some seven years, it was a masterpiece of its time because (1) being activated only when exposed to a low-energy radio signal which Soviet spies would transmit from outside, when subjected to a US “bug detection” it would appear to be a piece of wood and (2) as it needed no form of battery or other power supply (and indeed, no maintenance at all), its lifespan was indefinite.  Had it not by chance been discovered by a communications officer at the nearby British embassy who happened to be tuned to the same frequency while the Soviets were sending their signal, it may well have remained in place for decades.  Essentially, the principles of the Great Seal bug were those used in modern radio-frequency identification (RFID) systems.

1375-1425: From the late (northern) Middle English swirlen (to eddy, swirl) which was probably from the Old Norse svirla (to swirl), a frequentative form of Old Norse sverra (to swing, twirl).  It was cognate with the Scots swirl & sworl (to eddy, swirl), the Norwegian Nynorsk svirla (to whirl around; swirl), the Swedish sorla (to murmur, buzz) and the Dutch zwirrelen (to swirl).  Related forms included the dialectal German schwirrlen (to totter), the West Frisian swiere (to reel, whirl), the Dutch zwieren (to reel, swing around), the German Low German swirren (to whizz, whirl or buzz around), the German schwirren (to whirr, whizz, buzz), the Swedish svirra (to whirr about, buzz, hum), the Danish svirre (to whizz, whirr) and the English swarm.  The construct may be understood as the Germanic root swir- + -l- (the frequentative suffix).  Swirl is a noun & verb, swirled is a verb & adjective, swirling is a noun, verb & adjective, swirly is a noun & adjective, swirler is a noun and swirlingly is an adverb; the noun plural is swirls.

In English, the late (northern) Middle English noun swirlen (to eddy, swirl) seems originally to have come from a Scottish word, the origin of which is undocumented but etymologists seem convinced of the Scandinavian links.  The sense of a “whirling movement” emerged in the early nineteenth century although the meaning “a twist or convolution (in hair, the grain of wood etc)” was in use by 1786.  The verb as a transitive in the sense of “give a swirling or eddying motion to” was in use in the early sixteenth century but it may by then long have been in oral use, one text from the fourteenth containing an example and the source of that may have been either Germanic (such as the Dutch zwirrelen (to swirl) or the Norwegian Nynorsk svirla (to whirl around; swirl) or it may have evolved from the English noun.  The intransitive sense (have a whirling motion, form or whirl in eddies) dates from 1755.  The adjective swirly existed by 1785 in the sense of “twisted or knotty” but by the middle of the next century it had come also to describe anything “whirling or eddying”, applied especially to anything aquatic.  By 1912, it was used also to mean “full of contortions or twists” although “swirling” in this sense had by then been in (gradually increasing) use for a century.

Of curls & swirls: Lindsay Lohan with curls (left) and swirls (right).

In hairdressing, although customers sometimes use the words “curl” and “swirl” interchangeably, to professionals the use should be distinct.  A swirl is a movement or pattern in which hair is styled or arranged, typically with a rounded or circular pattern and swirls can be natural (the pattern at the crown of the head where the hair grows in a circular direction) or stylized (the look deliberately created and most obvious in “up-dos) or the formal styles associated with weddings and such).  The end result is a wide vista and the swirl is more a concept than something which exists within defined parameters.  A curl is (1) a type of hair texture or (2) the act of creating a curl with techniques using tools and/or product.  Some people (and there’s a strong ethnic (ie genetic) association) naturally have curly hair due to the shape of their follicles and within the rubric of what used to be called the ulotrichous, hairdressers classify curls as tyree types: (1) tight (small, corkscrew-like structures), (2) medium (tighter curls but with a softer appearance) and (3) long spirals with a large diameter).  Some commercial product also lists “ringlets” as a type but as tight, well-defined spirals, they’re really a descriptive variation of the tight or medium.  So, the essential difference is that a swirl is a pattern or movement of the hair, while a curl describes texture or shape and while a swirl is a matter or arrangement, a curl demands changing the hair’s natural texture or shape.  Swirls are very much set-piece styles associated with formal events while curls are a popular way to add volume, texture, and movement to the hair.

In internal combustion engines (ICE), the “swirl chamber is a now generic term used to describe a widely-used type of combustion chamber when upon introduction, the fuel-air mixture “swirls around” prior to detonation.  The design is not new, Buick’s straight-8 “Fireball” cylinder head using a simple implementation as long ago as the 1920s and it would serve the corporation into the 1950s.  The critical aspect of the engineering was the interaction between a receded exhaust valve and a rising in the top of the piston which “pushed” most of the fuel-air mixture into what was a comparatively small chamber, producing what was then called a “high-swirl” effect, the “Fireball” moniker gained by virtue of the actual combustion “ball of fire” being smaller in volume than was typical at the time.  The benefit of the approach was two-fold: a reduction in fuel consumption because less was required per power-stroke and (2) a more consistent detonation of the poor quality fuel then in use.  As fuel improved in quality and compression ratios rose (two of the dominant trends of the post-war years), the attraction of swirl chambers diminished but the other great trend was the the effective reduction in the cost of gasoline (petrol) and as cars became larger & heavier and roads more suited to higher speeds, the quest was for power.

Swirling around: The swirl process in a diesel combustion chamber.

Power in those years usually was gained by increased displacement & combustion chamber designs optimized for flow; significantly too, many popular designs of combustion chamber (most notably those in the so-called “wedge” heads) were cheaper to produce and in those years, few gave much thought to air-pollution.  The cars of the 1950s & 1960s had really toxic exhaust emissions.  By the mid 1960s however, the problem of air pollution in US cities was so obvious and the health effects were beginning to be publicized, as was the contribution to all of this by motor vehicles.  Regulations began to appear, California in 1961 (because of the high vehicle population and certain geographical & climatic phenomena, Los Angeles & San Francisco were badly affected by air pollution) passing the first statute and the manufacturers quickly agreed to adopt this standard nationally, fearing other states might begin to impose more onerous laws.  Those however arrived by mid-decade and although there was specific no road-map, few had any doubts the rules would become stricter as the years passed.  The industry’s only consolation was that these laws would be federal legislation so they would need to offer only one specification for the whole country (although the time would come when California would decide things should be tougher and by the 1970s there were “Californian cars” and “49 state cars”).  K Street wasn’t the force then it later became and the manufacturers conformed with (relatively) little protest.

Fuel was still cheap and plentiful but interest in swirl chambers was revived by the promise of cleaner burning engines.  Because it wasn’t new technology, the research attracted little attention outside of the engineering community but in 1970, German-born Swiss engineer Michael May (b 1934) demonstrated a Ford (Cologne) Capri with his take on the swirl chamber in a special cylinder head.  In a nod to the Buick original, May nick-named his head design the “Fireball” (professional courtesy a thing among engineers).  What Herr May had done was add a small groove (essentially a channel surrounding the intake valve) to the chamber, meaning during the last faction of a second of piston movement, the already swirling fuel-air mixture got a final nudge in the right direction: instead of there being a randomness to the turbulence of the mix, the shape was controlled and was thus able to be lower in volume (a smaller fireball) and precisely controlled at the point at which the spark triggered detonation; May called this a “higher swirl”.  Not only did this reduce exhaust emissions but it also cut fuel consumption for a given state of tune so designers could choose their desired path: more power for the same fuel consumption or the same power for less and within a short time, just about the whole world was taking great interest in fuel consumption.

Detail of the original "flathead" cylinder head of the Jaguar V12 (left) and the later "Fireball" head with swirl chambers (right).

A noted use of May’s design was its adoption in 1981 on Jaguar’s infamously thirsty V12 (1971-1997), an innovation celebrated by the addition of the HE (High Efficiency) label for the revised power-plant.  The notion of “high efficiency” was comparative rather than absolute and the V12 remained by most standards a thirsty beast but the improvement could be in the order of 40% (depending on conditions) and it was little worse than the similar displacement Mercedes-Benz V8s of the era which could match the Jaguar for power but not the turbine-like smoothness.  Threatened with axing due to its profligate ways, the swirl chambers saved the V12 and it survived another sixteen years which included two severe recessions.  Debuting even before the Watergate scandal, it lasted until the Monica Lewinsky affair.  In the decades since, computer simulations and high-speed photography have further enhanced the behavior of swirl & turbulence, the small fireballs now contained in the center of the chamber, prevent heat from radiating to the surrounding surfaces, ensuring the energy (heat) is expended on pushing the piston down to being the next cycle, not wasting it by heating metal.  The system is popular also in diesel engines.

Robot

Robot (pronounced roh-bot)

(1) A machine resembling a human, designed to perform certain functions.  Originally, the most popular were the “intelligent” mechanical beings which appeared in science fiction (SF) but of late advances in technology have encouraged manufacturers to build robots in humanoid form, the advantage being they can be applied to replace human labor using without the need to change existing infrastructure.

(2) A person who acts and responds in a mechanical, routine manner, usually subject to another's will; an automaton (often a figurative use).

(3) A device operating automatically, in a pre-programmed fashion.

(4) As a non-physical device (in software), a program which to some extent (including beyond) can duplicate or emulate human actions; now often called “bots”.

(5) As a modifier, a device not (directly) controlled by a human; something automated within certain parameters (such devices sometimes called “robot” in colloquial use).

(6) In surveying, a specialized form of theodolite which follows the movements of a prism and can thus be used by a single operator.

(7) In various forms of modern & modernist dance, a style in which dancers imitate the stiff and jerky movements of a stereotypical fictional robot.

(8) In various on-line communities, a habitual user who posts content of dubious or no value (in this case a human, not a bot in the modern sense)  In the earlier era of the bulletin boards an equivalent term was “slug” (which was probably worse than being labeled a “file pig”).

(9) In internet use (1) a computer-controlled character in a video game, especially a multiplayer one, (2) a dreadfully inempt player of video games and (3) a person thought to have no independent capacity for thought.

(10) Figuratively, a person who seems not to have emotions.

1920: Robot first appears (in the modern sense) in the play R.U.R. (Rossum's Universal Robots (1920)) by Czech writer Karel Čapek (1890–1938), the word suggested by his brother, the artist, writer & poet Josef Čapek (1887–1945).  R.U.R. was Čapek's first international success and was a dystopian vision of an industrial society and while sometimes compared to Charlie Chaplin’s (1889–1977) Modern Times (1936), thematically, they’re quite different.  Typically, the word was brought unchanged into English but such was the simplicity of form that many languages have also retained the spelling, the odd variation including the Japanese robotto (ロボット) and the Swahili roboti.  Surprisingly, despite what must be a temptation, ROBOT is a rare construction as an acronym.  Robot, robotics, robotism, robotry, roboticization & roboticist are nouns, robotic, robotistic, robotical & robotlike (and the non-standard robotesque) are adjectives, robotize (also as roboticise) is a verb and robotically is an adverb; the noun plural is robots.

The Czech-derived robot (mechanical person, also “person whose work or activities are entirely mechanical”) was from robota (drudgery, servitude, compulsory labor) and robotník (the landless peasant so employed (although that was also sometimes applied to “richer peasants” (al la the Russian кула́к (kulák) (wealthy peasant) who employed their own roboniks), from robotiti (to work, drudge), from an Old Czech source akin to the Old Church Slavonic rabota (servitude), from rabu (slave), from the Old Slavic orbu-, from the primitive Indo-European orbh- (pass from one status to another (and related to the later English “orphan”)).  The German noun Robot, was used to refer to a system of serfdom in Central Europe, under which a tenant's rent was paid in forced labor and the Slavic thread is related to the German Arbeit (work), from the Old High German arabeit. 

Several derived forms entered the language after appearing in Liar! (1941, a short story by Russian-born US SF author Isaac Asimov (1920-1992) including the adjective robotic (of or characteristic of robots) and the nouns robopsychologist (one who studies or practices the discipline of robopsychology) & robotics (the science of robots, their construction and use) and earlier, in Robbie (1940 and first published as Strange Playfellow), he’d introduced roboticist (one who conceptualizes, designs, builds, programs, and experiments with robots).  Asimov’s Three Laws of Robotics (1968) is often quoted as the basic framework of protocols which should be adopted as a regulatory environment for the industry.

Daleks: The original BBC series was broadcast in black & white which made life easier for the props department but the cyborg Daleks later came in designer colors.

“Bot” has become familiar in the internet era to describe software implementations which appear (sometimes deliberately) to be actual humans but it has a long history.  According to the authoritative Online Etymology Dictionary, “bot” as a head-clipping of “robot” was unknown until around the turn of the twenty-first century and remarkably: “The method of minting new slang by clipping the heads off words does not seem to be old or widespread in English.  The examples (za from pizza, zels from pretzels, rents from parents, burbs from suburbs) are American English student or teen slang and seem to date back no further than the late 1960s.”  Bot has flourished as have (cy)borg & (an)droid and there is sometimes genuine linguistic innovation in the field:  The name of the cyborg (a combination of robotics and a biological intelligence) Daleks in the BBC Dr Who television series was an invention with no etymological basis.

Long before computers and robots, “bot” had a history.  In the early sixteenth century, in what was thought an alteration of the Scottish Gaelic boiteag (maggot), in both England a Scotland, bot (and bott) meant “the larva of a botfly, which infests the skin of various mammals, producing warbles, or the nasal passage of sheep, or the stomach of horses”.  Unrelated to that (hopefully), was the eighteenth century English slang (often as the verbs botting & botted) meaning “to buggar” (ie the old criminal offence of “the abominable crime of buggery”).  Presumably an independent evolution was the now obsolete Australian slang meaning “to ask for and be given something with the direct intention of exploiting the thing’s usefulness” and dictionaries of slang suggest it was used almost exclusively of cigarettes (ie “can I bot a smoke?” a alternative form of “can I bum a smoke?”, the latter form now rare but still heard.  The World War I (1914-1918) era slang in Australia & New Zealand indicating a “"worthless, troublesome person” is extinct.  Strangely, given the document fondness for clippings & abbreviations in the camp lexicon, “bot” seems never to have emerged as a form of “bottom” which, in gay (male) slang, is the companion term for “top”.

Of late, additions to the language have included robothood (the state or condition of being a robot; an environment largely or exclusively inhabited by robots), robotless (a place, institution or device in which robots are not used) and fembot (a female version of a robot).  Note that fembot is used in different ways.  In SF, fembots could genuinely be “female robots” for in the genre not only could there be actual genders (as opposed to the mere representation of characteristics) but there was not of necessity any need for the number of different sexes to be restricted to two.  In real-world use, voice fembots were among the earliest widely to be deployed and that was because the research made clear the female voice tended to be preferred (by men and women), thus the “talking clocks”, automated switchboard attendants etc usually being feminine.  In (derogatory) figurative use, fembot was used also to suggest a docile, unthinking and conformist woman (something like a mature version of the “basic bitch”), the idea explored in Ira Levin’s (1929—2007) The Stepford Wives (1972); the “feminist horror” genre remains still sadly neglected.  Advances in artificial intelligence (AI), robotics and sensors have in recent years made fembots notably more “realistic” and fembots have already been deployed in two of the oldest of the “feminized” professions: sex work & health care.

In medicine, the possibilities had been discussed for decades but the first products emerged in the 1980s as technology caught up with the most simple of the ambitions, robotic arms for use in simple procedures the first commercially available.  Progress was incremental until the last ten years although robotics did make a significant contribution to research, not only taking the place of human labor but making possible projects which would never otherwise have been possible because some of the big data analysis would have required so much labor that funding would never have been available.  The evolutionary pattern in the industry will likely follow the same path as in the legal professional in that the first human jobs to go are those in back-office and other administrative functions before ancillary roles are also absorbed by machines.  The clinicians will be last to be thinned from the hollowed-out middle while at the upper end, executive roles will continue and perhaps even expand while at the lowest level, cleaners, porters, security guards and such may endure, not because machines can’t be built to do the jobs but the nature of the duties is such the attrition rate will for the foreseeable future make human labor cheaper.

Grace the bot, coming to a hospital near you.

The use of fembots as ancillaries in clinical health care will of course be the thin end of the wedge because a fembot can instantly recall the complete medical history of all patients in a hospital while simultaneously possessing an unparalleled degree of medical knowledge, dynamically updated minute by minute.  Already, machines are proving better than humans in fields such as the analysis of diagnostic imagery and in the near to mid-term, the only obvious disciplines in the field where they’re likely to remain at a disadvantage is in certain surgeries and other activities where physical dexterity or the ability to execute intricate movements is at a premium.  Years from now (and there’s genuine debate about how many), those wishing to pursue a career in medicine might find psychiatry remains the last human preserve, at least for those tending to the rich; the poor will be relegated to pacifying drugs and bots. 

A Harmony 2.0 in completed form.

As sex dolls, progress has been followed with great interest and the most interesting aspect has been the extent of the focus on communication, the manufacturers clearly responding to demand from men for a “relationship” and not merely a more elaborate and life-like sex toy.  The phenomenon of “lonely Japanese Men” has for some time been well-documented and it’s unlikely the problem is culturally specific so such demand is likely to exist also in other markets.  Manufacturers in the Far East have been active but so are players in Europe and the US and with the mechanical challenges “substantially” solved, attention has turned to emotions and their physical manifestations.  In April 2023, US-based Abyss Creations displayed what was described as a “new generation sexbot”, “Harmony 2.0” said to have the ability to learn from “her human companion” a greater range of emotions which subsequently can be generated, including tears.  Technology site CNET reported Harmony can be customized and is interactive, conversations able to be conducted, the quality of which will improve over time because the sexbot will learn from the experience; thus the emotional range of one Harmony 2.0 will differ from another which has been interacting with a different companion.  Memory is persistent and Abyss have indicated that at some time in the future, a greater range of “pre-loaded personalities” will be available, users able to choose “their type”, some presumably preferring a quiet and deferential sexbot, others something more highly strung.  Like anything, it’s all a question of what one wants from life (a male version is said to be “in development”) and being a software download, the implication is that if the personality of one’s Harmony 2.0 proves unsatisfactory, the memory can be over-written with something which hopefully proves better.  By default, Harmony has 18 distinct personality traits such as such as “shyness” or “strong sexual desire”; there seems no proneness to headaches although, at the software level, there’s no reason why one couldn’t be trained to display anything from aversion to sex to actual frigidity.  Again, it’s all a matter of what one wants from life and one can map one’s kinks onto one’s Harmony 2.0.

Mix & match: Being modular, there is a Harmony app (a subscription service) with which users can “build their bot”, customizing it according to one’s preferences (appearance and personality).

A Harmony 2.0 requires some 80 hours of labor to complete and every detail is said to be “perfect” (ie conforming to the desired specification) and the devices are modular.  This is familiar from the model used to build industrial robots where the one core design could be adapted to welding, component placing, painting or a range of other activities, simply by swapping attachments like arms and changing software instruction sets.  With sexbots, the modularity focuses more on aesthetic elements such as hair, eyes, mouths, breasts and such.  At the time of release, Abyss listed Harmony 2.0 at US$6,500 while the “tearful” version was US$12,000, reflecting both the development costs and the additional hardware (presumably plumbing including a “tear reservoir”) required.  Sexbots may only ever be a market niche but in a sense, it’s the oldest niche in the world.

Polysphere

Polysphere (pronounced pol-ee-sfeer)

(1) In mathematics, a product of spheres.

(2) In mechanical engineering, a design of combustion chamber formed by the two shallow concave domes under the intake and exhaust valve seats.

1955: A compound word, the construct being poly + sphere.  Poly is from the Ancient Greek πολύς (polús or polys) (many, much), from the primitive Indo-European polhiús (much, many) from the root pele (to fill), akin to the Old English fela (many).  Sphere is from the Middle English spere, from the Old French spere, from the Late Latin sphēra, from the Classical Latin sphaera (ball, globe, celestial sphere), from the Ancient Greek σφαῖρα (sphaîra) (ball, globe), of unknown origin.  Despite spread of the myth by some medieval writes, sphere is not related to superficially similar Persian سپهر‎ (sepehr) (sky).  Poly, in modern English (especially in industrial and scientific application) use became a word-forming element meaning "many, much, multi-, one or more" with derivatives referring to multitudinousness or abundance.  It was equivalent to the Latin multi- and should properly be used in compounds only with words of Greek origin but this, etymologically slutty English ignores.  Polysphere is a noun and polyspheric is an adjective; the noun plural is polyspheres.

Chrysler, the poly, the hemi and the hemi which is really a poly

Chrysler didn’t invent hemispherical combustion chambers but they certainly made a cult of them.  In internal combustion engines of the mid-late twentieth century, the hemispherical combustion chamber was one of the best designs with with to provide an efficient burn-space while minimizing thermal loss and permitting the use of large diameter canted-valves to optimize intake and exhaust flow.  The early Chrysler Hemi V8s (1951-1958) were the most powerful of their generation but there were drawbacks.  To take advantage of the large valves at diverging angles, the valve train assembly was both bulky and heavy, needing two rocker shafts rather than the single units used with in-line arrangements.  Adding to the cost and complication were the inherently more expensive casting and machining processes required to produce the hemispherical shape of the combustion chambers in the cylinder heads.  To enable the mass-production of a less expensive V8 to use in their lower-priced lines, Chrysler created new cylinder heads with polyspheric (two shallow concave domes under the valves and named the “Poly”) combustion chambers and a less elaborate system of valve activation which needed only a single rocker shaft.  Although less powerful than the Hemis, the Polys were cheaper and lighter although it wouldn’t be until the 1960s that Chrysler standardized engines across their divisions; an early adoption of such economies of scale might have saved the corporation more money than retaining an exclusively Hemi-headed line would have cost.

The Hemi, 1951-1958 & 1964-1971 (left), the polyspheric, 1955-1967 (centre) and the new "Hemi" which is really a swirl Chamber, 2003- (right).

However, the Poly proved a cul-de-sac.  In an era of cheap petrol, larger capacity engines proved a more attractive route to horsepower than sophisticated combustion chamber design and the Hemis were retired in 1958, replaced by larger engines with wedge-shaped chambers, used by other manufacturers and much more suited to mass-production.  Consigned to the grave with the Hemis were almost all the Polys, only the 318 V8 (5.2 litre) retained as a rare oddity until 1967.  The Hemi would return, available between 1964-1971 as a 426 cubic inch (7.0 litre) race engine (there were also some reduced displacement versions to satisfy local rules) which, for homologation purposes would in 1966 be released in slightly detuned form detuned for street use.  The name however held such an allure that it was revived in 2003 for Chrysler's new (and perhaps final) generation of V8s although in the narrow technical sense, Hemi is now more a marketing than an engineering term because the twenty-first century combustion chambers are something of a hybrid of hemispheric and polyspheric, the general term describing them for the last fifty-odd years being swirl chambers, a design which makes possible a high out-output of power, low emissions and an economy in operation which would have been thought impossible to achieve as recently as the 1980s.

Lindsay Lohan with polyspheric hair.  Polyspheric hair styles are possible, the classic example of which is the symmetrical “twin dome” look which is difficult exactly to achieve and harder still to maintain for more than a brief time.  They’re thus seen usually only at photo-shoots or for one-off events but the design element is popular with asymmetric styles.

When Chrysler in 1964 introduced the 273 cubic inch (4.5 litre) V8 as the first of its LA-Series (that would begat the later 318, 340 & 360 (the V10 Magnum used in the Dodge Viper is also as descendent)), the most obvious visual difference from the earlier A-Series V8s was the noticeably smaller cylinder heads.  The A engines used as skew-type valve arrangement in which the exhaust valve was parallel to the bore with the intake valve tipped toward the intake manifold (the classic polyspherical chamber).  For the LA, Chrysler rendered all the valves tipped to the intake manifold and in-line (as viewed from the front), the industry’s standard approach to a wedge combustion chamber.  The reason for the change was that the decision had been taken to offer the compact Valiant with a V8 but it was a car which had been designed to accommodate only a straight-six and the wide-shouldered polyspheric head A-Series V8s simply wouldn’t fit.  So, essentially, wedge-heads were bolted atop the old A-Series block but the “L” in LA stood for light and the engineers wanted something genuinely lighter for the compact (in contemporary US terms) Valiant.  Accordingly, in addition to the reduced size of the heads and intake manifold, a new casting process was developed for the block (the biggest, heaviest part of an engine) which made possible thinner walls.  With the exception of the Hemis, the new big-block engines used wedge-heads and the small block polyspheres (the A-Series) were replaced by the LA except for an export version of the 313 (5.1 litre) which in small numbers was manufactured until 1965 and the 318, the last of which was fitted in 1967.  Confusingly, the replacement LA engine was also a 318, a product of carrying over certain components, both the 318-A & 318-LA sharing the same bore & stroke.  In an example of production-line rationalization, when Chrysler Australia bored out their 245 cubic inch (4.0 litre) Hemi-6 to create the 265 (4.3), the bore chosen was the same as the 318s so pistons could have been shared with the V8 although for technical reasons this wasn't actually done.  The Australian "Hemi" straight sixes used another variation of the combustion chamber in that chambers sat in upper third of the globe, hence the "low hemispherical" slang which wasn't wholly accurate but Ford's Boss 429 V8 had already been dubbed the "semi-hemi" and linguistic novelty was becoming hard to find.
