Pre 900: From the Middle English wegge, from the Old English wecg (a wedge), from the Proto-Germanic wagjaz (source also of the Old Norse veggr, the Middle Dutch wegge, the Dutch wig, the Old High German weggi (wedge) and the dialectal German Weck (a wedge-shaped bread roll) and related to the Old Saxon weggi.  It was cognate with the dialectal German weck derived from the Old High German wecki and Old Norse veggr (wall).  The Proto-Germanic wagjaz is of uncertain origin but may be related to the Latin vomer (plowshare).  From the early fifteenth century, the verb form emerged in the sense of "jam in place with a wedge; tighten with a wedge", the figurative sense "drive or pack (into)" dating from 1720.  The meaning "split (something) apart with a wedge" is attested from 1853.  The general use to describe things shaped like a wedge began in the 1610s and use of the phrase "thin edge of the wedge" meaning a minor change that leads to a major change, especially one thought undesirable, dates from the mid nineteenth century.

Wedge Politics

Wedge politics is the art of identifying an issue of importance to one’s own political base but which polarises opinion in that of one’s political opponents.  A wedge issue is of a controversial or divisive nature (guns, abortion, refugees etc) which splits apart a demographic or population group which tends to be clustered in the voting base of an opposing political party.  Wedge issues can be advertised or publicly aired in an attempt to weaken the unity of a population, with the goal of enticing polarized individuals to give support to an opponent or to withdraw their support entirely out of disillusionment.

Some dictionaries cite 1999 as the origin of wedge issue as a phrase but it dates from 1990, in the run-up to that year’s mid-term US congressional elections.  A official under Jimmy Carter (b 1924; US President 1977-1981), Stuart Eizenstst (b 1943; Chief Domestic Policy Adviser and Executive Director, White House Domestic Policy Staff 1977-1981) coined the term to describe the tactics being deployed under George HW Bush (George XLI, 1924-2018; US president 1989-1993) to use affirmative action guidelines and quotas as issues “…to split the coalition of working-class whites and blacks, the two constituencies Franklin Delano Roosevelt (FDR, 1882–1945, US president 1933-1945) unified on economic grounds.  The image came to mind of a wedge being driven."  It was a refinement of what emerged during the Reagan presidency, the use of social issues to persuade the working-class to vote against their own economic interests.  In the jargon of political science, they’re also called third rail issues.  It filled a political-linguistic need for fresh labels.  As a phrase, wedge issue had a certain earthy appeal, a wedge being a familiar and vivid metaphor, more memorable than the earlier usage hot-button issue, which was too vague to summon the mental imagery and more widely used and understood than the Latinate polarization so beloved by political scientists.  Generational change means wedge issues can return to haunt the authors.  In the 1990s, gay marriage was used successfully by the Republicans to drive a wedge between the liberal and conservative wings of the Democratic Party but within a quarter-century, the universe had shifted and it was the Republicans fractured by the issue.  The hunter had been captured by the game.

The Wedge Combustion Chamber

So-named because the inside top of the cylinder head is shaped like an inclined basin, with the valves sitting at an angle so that the space between the piston and cylinder head looks like a wedge, wedge-shaped combustion chambers have been used by almost every mainstream manufacturer of internal combustion engines.  A relatively simple design, the chamber resembles an inclined basin recessed into the deck of the head, the fuel/air mix supplied (usually) by inline valves, often tilted to accommodate the sloping roof.  The spark plug tends to be located on the thick side of the wedge, positioned most often midway between the valves.

Designed to exploit the nature of fluid dynamics, the chamber’s steep walls deflect the air/fuel flow path, forcing it to move in a downward spiral around the cylinder axis.  During the compression stroke, the compressed air/fuel area reduces to such an extent that the trapped mixture is violently thrust from the thin to the thick end of the chamber, building up significant kinetic energy, which, when ignited, improves the burn rate and thus the extraction of energy: the power.  Another advantage, refined particularly from the mid 1970s, is that the wedge-shaped combustion chamber tends to have a smaller surface area than other designs and so there is less space on which droplets can condense, assisting in reducing the volume of fuel remaining unburnt after the combustion cycle, thus reducing hydrocarbon emissions.  Ultimately, the wedge-shaped combustion chamber is not as efficient or able to produce as much power as other designs but is well-suited to engines which need to deliver a compromise between torque, power and economy over a wide operating range.  It has the additional benefit of being inherently cheaper to build than others because of the simplicity of the casting and machining processes required and the structure of its valve train tends to require fewer moving parts.

Sandwedge

Sandwedge (pronounced sand-wej)

(1) As Operation Sandwedge, a proposed clandestine intelligence-gathering operation against the political enemies of US president Richard Nixon.

(2) As sand wedge, a specialized golf club, an iron with a heavy lower flange, the design of which is optimized for playing the ball out of a bunker (sand trap).

1971: The name was chosen for a “dirty tricks” covert operation as a borrowing from golf, the sand wedge a club used to play the ball from a difficult position.  The construct was sand + wedge.  Dating from pre-1000, sand was from the Middle English sand, from the Old English sand, from the Proto-West Germanic samd, from the Proto-Germanic samdaz, from the primitive Indo-European sámhdhos, from sem- (to pour).  Wedge was a pre 900 from the Middle English wegge (wedge), from the Old English wecg (a wedge), from the Proto-Germanic wagjaz (source also of the Old Norse veggr, the Middle Dutch wegge, the Dutch wig, the Old High German weggi (wedge) and the dialectal German Weck (a wedge-shaped bread roll) and related to the Old Saxon weggi.  It was cognate with the dialectal German weck derived from the Old High German wecki and Old Norse veggr (wall).  The Proto-Germanic wagjaz is of uncertain origin but may be related to the Latin vomer (plowshare).  Sandwedge is a noun; should the plural ever be needed, it would be sandwedges (ie phonetically a la the use in golf (sand wedges)).

In golf, when using a sand wedge (left), the player’s stance and the way in which the club addresses the ball differs from what’s done when using a conventional iron (right).  Noted golfer Paige Spiranac (b 1993) demonstrates the difference although there may be some variations depending on an individual's weight distribution. 

Richard Nixon.

Operation Sandwedge was a covert intelligence-gathering operation intended to be conducted against the enemies (a long list which later became public) of Richard Nixon (1913-1994; US president 1969-1974).  Beginning in 1971, the early planning was done by Nixon's Chief of Staff HR Haldeman (1926-1993), his assistant for domestic affairs, John Ehrlichman (1925-1999) and Jack Caulfield (1929–2012), then attached to Ehrlichman’s White House staff “handling special assignments”; also involved (though paid not by the White House but from external campaign funds) was Tony Ulasewicz (1918-1997), later a bit-player in the Watergate affair.  The core of Caulfield’s plan was to target the anti-Vietnam War movement and those figures in the Democratic Party Nixon had identified as the greatest threat to his re-election in 1972, including Ted Kennedy (1932–2009; US senator 1962-2009), Ed Muskie (1914–1996; US senator 1959-1980), William Proxmire (1915–2005; US Senator 1957-1989) and Birch Bayh (1928–2019; US senator 1963-1981).  Of interest too was a settling of scores with those who had prevented G Harrold Carswell (1919–1992) being confirmed by the Senate as Nixon's nominee for the US Supreme Court and the president's net was internecine too, some of the targeted figures in his own Republican Party.

G Gordon Liddy.

Operation Sandwedge was intended to be clandestine but it wasn’t subtle and included physical and electronic surveillance, the intelligence of particular interest that which could be used either to feed damaging leaks to the press or for purposes of blackmail including dubious financial transactions, mental health records and (preferably “unnatural”) sexual proclivities.  However, the operation never proceeded beyond the planning stages because Haldeman and Ehrlichman thought the methods of Caulfield (a former New York City Police Officer) unsophisticated so transferred the project to G Gordon Liddy (1930–2021), a lawyer, one-time FBI agent and later one of the great characters of the Watergate affair.  Attached to Liddy's operation was former CIA operative Howard Hunt (1918–2007) who, under his name and many noms de plume, was a most prolific author of fiction and non-fiction, his bibliography extending to over 70 titles.  Caulfield had chosen the name sandwedge because, as a dedicated golfer, he knew the sand wedge was the club of choice when one was in a difficult spot;  if well-played, it was what could transform a bad situation into something good.  At the time, code-names were among the many imaginative things to emerge from the bunker at 1600 Pennsylvania Avenue and the one chosen for the squad to investigate leaks of information to the press was dubbed “the plumbers”.  One member later told his elderly grandmother one of his duties in the White House was “investigating leaks” and proudly she told him: “Your grandfather was a plumber”.

The Watergate complex, Washington DC.

The Watergate affair was of course one of the best known (and among nihilistic political junkies the most celebrated) of the “dirty tricks” operations run out of (or at least connected with) the Nixon White House but it was far from unique.  Some strikingly immoral back-channel operations had been run even before the 1968 election but by 1971 the vista had expanded to include what would now be called fake news plants, the infiltration of the staff of political opponents, break-ins and burglary, among the most infamous of which was “the plumbers” (including Liddy) breaking into the office of the psychiatrist treating Daniel Ellsberg (b 1931), the former Department of Defense (now known also as the Department or War) military analyst who had leaked the “Pentagon Papers” (something which was a reasonable achievement in the days when decamping with thousands of pages of classified material demanded not a few minutes copying data to a USB stick but many hours between midnight and dawn using the photocopier).  The doctor's Ellsberg file revealed nothing of interest but the burglary gained a place in history, being recorded by Ehrlichman (who approved the operation) as "Hunt/Liddy Special Project No 1".  There would be more.

Paige Spiranac is active on Instagram and recently posted a “Life update” to her four million followers, advising “I have bangs now”.  Hopefully, she will keep us informed and there will be more to come.

Sandwedge had been envisaged as an intelligence gathering operation, the most novel aspect of which was that while the project documents presented an overview of something using conventional methods of surveillance and the compilation of publicly available material, privately, Caulfield admitted electronic surveillance would also (unlawfully) be used, something any expert presumably could have deduced from the impressive total of budget request.  Of greatest interest were financial records (relating particularly to tax matters), mental health conditions, undisclosed legal problems and sexual conduct, especially if illicit and preferably unlawful.  The idea greatly interested Haldeman and Ehrlichman but they had never been convinced by Caulfield’s “lack of background” by which they meant education, social skills (ie correct way to use knife & fork in polite company) and political experience.  Accordingly, Sandwedge and all intelligence matters were transferred to Liddy, the article of faith in the White House being anything run by a trained lawyer legally would be “bullet proof”, not a quality they associated with the schemes of ex-NYC police officers, a breed not always with a reputation for rectitude.

New York Times, Saturday 2 March 1974.

Liddy revelled in the role as the White House’s clandestine clearing house for “covert ops” and applied his own list of spy-like code names (Gemstone, Diamond, Ruby etc) to an range of activities expanded beyond Sandwedge including physical espionage, infiltration of protest groups, secret wire-taps, sabotage of opposition campaigns and, of course, “honey-pot traps” (the use of attractive young women as temptresses).  Even for Haldeman and Ehrlichman (behind their backs, known to White House staffers as “the Germans” or “the Prussians”) the implications of becoming essentially gangsters was too much but the shell of Liddy's structure was in 1972 approved and even that pared-down framework included a range of unlawful activities, including the one which would trigger the chain of events that culminated in Nixon’s resignation and see dozens of the conspirators (including Haldeman, Ehrlichman and Liddy) jailed: the break in and bugging of the Democratic Party offices in the Watergate complex.  As the affair unfolded, suspicion fell upon Caulfield until it was realised his role in Operation Sandwedge had ended before any dubious operations began and he’d never been part of Liddy’s more ambitious plans.  He was compelled to resign from government but was never prosecuted, maintaining to his dying day that if he’d been left to run Operation Sandwedge, there would have been no burglaries in the Watergate complex or anywhere else and thus none of the cascading scandals which at first paralysed and later doomed the second term of the Nixon administration.

One attractive thing about the historic records of the US government is the relative openness and accessibility to the documents which can lay bare the operations of at least some of the machinery of government.  Things are of course not as open as they used to be but the US attitude to the classification of material is still preferable to that of institutions like the UK’s Cabinet Office or the CCP (Chinese Communist Party) both of which operate in an air of obsessive secrecy.  One treasure trove is the on-line archive of the Richard Nixon Presidential Library and Museum which includes a stash of transcripts of the White House tapes subpoenaed by the SSPF (Watergate Special Prosecution Force), including the famous (and politically fatal) “smoking gun tape”.  In some ways even more so than the audio tapes, the transcripts provide an insight into how politics actually is practiced and it’s useful to compare them with sanitized (and sometimes mendacious) memoirs or “official histories”.  On 21 March 1973, President Nixon met with John Dean (b 1938; White House Counsel to the President, 1970-1973) when “Operation Sandwedge” and its corrosive consequences were discussed:

DEAN:  I think, I think that, uh, there's no doubt about the seriousness of the problem we've got.  We have a cancer--within, close to the Presidency, that's growing.  It's growing daily.  It's compounding, it grows geometrically now because it compounds itself.  Uh, that'll be clear as I explain you know, some of the details, uh, of why it is, and it basically is because (1) we're being blackmailed; (2) uh, people are going to start perjuring themself very quickly that have not had to perjure themselves to protect other people and the like. And that is just--and there is no assurance…

DEAN: Jack [Caulfield] had worked for John [John Mitchell (1913–1988; US attorney-general 1969–1972)] and then was transferred to my office.  I said, "Jack, come up with a plan that, you know, is a normal infiltration, I mean, you know, buying information from secretaries and all that sort of thing."  He did, he put together a plan.  It was kicked around, and, uh, I went to Ehrlichman with it.  I went to Mitchell with it, and the consensus was that Caulfield wasn't the man to do this. Uh, in retrospect, that might have been a bad call, 'cause he is an incredibly cautious person and, and wouldn't have put the situation to where it is today.

PRESIDENT: Yeah.

DEAN: All right, after rejecting that, they said, "We still need something," so I was told to look around for somebody that could go over to 1701 and do this.  And that's when I came up with Gordon Liddy, who-- they needed a lawyer. Gordon had an intelligence background from his FBI service.  I was aware of the fact that he had done some extremely sensitive things for the White House while he'd been at the White House, and he had apparently done them well. Uh, going out into Ellsberg's doctor's office.

PRESIDENT: Oh, yeah.

PRESIDENT: January of '72?

DEAN: January of '72.  Like, "You come over to Mitchell's office and sit in on a meeting where Liddy is going to lay his plan out."  I said, "Well, I don't really know as I'm the man, but if you want me there I'll be happy to."  So, I came over and Liddy laid out a million dollar plan that was the most incredible thing I have ever laid my eyes on.  All in codes, and involved black bag operations, kidnapping, providing prostitutes, uh, to weaken the opposition, bugging, uh, mugging teams. It was just an incredible thing.

PRESIDENT: But, uh..

DEAN: And--

PRESIDENT: ...that was, that was not, uh...

DEAN: No.

PRESIDENT: ...discussed with..

DEAN: No.

PRESIDENT: ...other persons.

DEAN: No, not at all. And--

PRESIDENT: (Unintelligible)

DEAN: Uh, Mitchell, Mitchell just virtually sat there puffing [on his pipe] and laughing. I could tell 'cause after he--after Liddy left the office I said, "That's the most incredible thing I've ever seen.  "He said, "I agree."  And so then he was told to go back to the drawing boards and come up with something realistic. So there was a second meeting. Uh, they asked me to come over to that. I came into the tail end of the meeting. I wasn't there for the first part. I don't know how long the meeting lasted. Uh, at this point, they were discussing again bugging, kidnapping and the like. And at this point I said, right in front of everybody, very clearly, I said, "These are not the sort of things that are ever to be discussed in the office of the Attorney General of the United States"--where he still was--"and I am personally incensed." I was trying to get Mitchell off the hook, uh, 'cause—

PRESIDENT: I know

DEAN: He's a, he's a nice person, doesn't like to say no under--when people he's going to have to work with.

PRESIDENT: That's right.

DEAN: So, I let, I let it be known. I said, "You all pack that stuff up and get it the hell out of here 'cause we just, you just can't talk this way in this office and you shouldn't, you shouldn't, you should re-examine your whole thinking." Came back-

PRESIDENT: Who else was present? Be-, besides you-

DEAN: It was Magruder, Magruder [Jeb Magruder (1934–2014; deputy director of Committee for the Re-Election of the President (CRP) in the 1972 election (better known as CREEP))]

PRESIDENT: Magruder.

DEAN: Uh, Mitchell, Liddy and myself. I came back right after the meeting and told Bob, I said, "Bob, we've got a growing disaster on our hands if they're thinking this way.'  And I said, "The White House has got to stay out of this and I, frankly, am not going to be involved in it."  He said, "I agree John."  And, I thought, at that point the thing was turned off. That's the last I heard of it, when I thought it was turned off, because it was an absurd proposal.

PRESIDENT: Yeah.

DEAN: Liddy-I did have dealings with him afterwards. We never talked about it. Now that would be hard to believe for some people, but, uh, we never did. Just the fact of the matter.

PRESIDENT: Well, you were talking about other things.

DEAN: Other things. We had so many other things.

PRESIDENT: He had some legal problems at one time.

Slope

Slope (pronounced slohp)

(1) To have or take an inclined or oblique direction or angle considered with reference to a vertical or horizontal plane; slant.

(2) To move at an inclination; obliquely to move.

(3) To direct at a slant or inclination; incline from the horizontal or vertical.

(4) To form or describe something with a slope or slant.

(5) A descriptor of ground or some aspect of the natural or built environment which has an incline, such as a hill.

(6) An inclination or slant, especially downward or upward; to lie or cause to lie at a slanting or oblique angle.

(7) Any deviation from the horizontal or vertical; an inclined surface.

(8) In mathematics, (1) the tangent of the angle between a given straight line and the x-axis of a system of Cartesian coordinates; (2) the derivative of the function whose graph is a given curve evaluated at a designated point.

(9) In slang, a disparaging and offensive term used to refer to a person of East Asian appearance.

(10) As slope off, a slang term (mostly UK, Australia & New Zealand) describing someone moving slowly, or furtively away, usually to avoid work or responsibility; a rare variation is “sloped-in”, used to describe to who arrive somewhere surreptitiously (those late for work etc).

(11) To follow an inclined course down a hillside (applied especially to natural features).

(12) In military use, as slope position, a drill command referring to the position in which a long-arm should be held.

1495–1505: From Middle English slope (go in an oblique direction), from the earlier adjectival meaning “slanting”, an aphetic variant of the Middle English aslope, from the Old English aslopen, past participle of āslūpan (to slip away), the construct being a- (away) + slupan (to slip).  From 1709 slope was used to mean "to be in a slanting position", the transitive sense "place in a slanting position" having been part of the language since circa 1600.  The derogatory slang meaning "oriental person" is attested from 1948.  Slopingly is an adverb, slopingness, sloper & slope are nouns, sloped & sloping are adjectives and sloped & sloping are verbs.

The slippery slope and the thin end of the wedge

Borrowed from political science, the terms “slippery slope” and “thin end (sometimes edge) of the wedge” are sometimes used interchangeably but, while both refer to similar processes, there are nuances which distinguish the two.  The idea is that a small, minor and perhaps innocuous change or innovation affecting something can trigger a chain of events which might result in unintended consequences; in that there are similarities with chaos theory but a slippery slope is much more specific and probably lineal.  There’s often overlap between the two and the distinctions are not always absolute but circumstances usually tends more to one than the other.  Both tend to be used in political discourse by extremists and fanatics and are often example of what is called the “slippery slope fallacy” such as the argument that if gay marriage is allowed, eventually the gay people will be allowed to marry their goats.  That argument really was raised by some who claimed it wasn't an extreme position to take, pointing out that two generations earlier, those who had been opposed to the decriminalization of homosexuality because it would put society on a slippery slope towards gay marriage had been accused of raising a “slippery slope fallacy”.  All things considered, goats seem safe.  The slippery slope is also a piece of imagery adopted sometimes by black-letter-law judges who oppose judicial activism.

The difference is essentially in the dynamics driving the process.  On a slippery slope, things happen because of the inherent inertia; the notion that of sitting on a slippery slope, the slide downhill an inevitable consequence of the physics of fluid dynamics and the force of gravity.  The downward path will happen naturally.  By contrast, the model of the thin end of the wedge is that of the wedge driven into the tree.  If left there nothing will happen but if the woodsman continues to hammer the edge into the trunk, at some point, the tree will fall.  An example of the thin end of the wedge was the deployment in the early 1960s by the Kennedy administration (1961-1963) of a small number of military advisors to support the government of South Vietnam.  It had never been intended that large-scale combat operations would be undertaken in Vietnam but, step-by-step, Washington increased the commitment.  An more familiar example of the slippery slope is to adopt a rigorous diet and then allow a weekly “cheat day”.  On the first cheat day, one might have just the one chocolate biscuit but the next week it’s a biscuit and a donut and within weeks it’s packets of both.

Anthony Trollope’s (1815-1882) 1857 novel Barchester Towers is set in a tranquil and leafy town but there are few novels which, without even a threat of bloodshed, so successfully and with such subtlety impart such feelings of incipient evil and a relentless undercurrent of dread.  In Victorian novels there were many characters of dubious virtue but few not actually homicidal managed to induce in readers such feelings of unease and distaste as the slimy Reverend Obadiah Slope.

Although said to be “tall and not ill made”, Slope was “saucer-eyed”, his hair “lank, and of a dull pale reddish hue… formed into three straight lumpy masses, each brushed with admirable precision, and cemented with much grease.”  His face, “perhaps a little redder” than his hair, not unlike beef “of a bad quality”, a “redeeming feature” his nose which was “pronounced, straight, and well-formed” although marred still by “a somewhat spongy, porous appearance, as though it had been cleverly formed out of red colored cork".  The description of the nose is not without significance for it had by some been asserted that he was of lineal descent from Dr Slop, “that eminent physician who assisted at the birth of Mr Tristram Shandy, and that in early years he added an ‘e’ to his name, for the sake of euphony.”  Shandy, the eponymous character from Laurence Sterne's (1713-1768) nine volume work (1759-1757), The Life and Opinions of Tristram Shandy, Gentleman, was birthed by the “man-midwife” Dr Slop, who squashes Tristram's nose with forceps as he yanks the baby out.

On the slopes: Lindsay Lohan in Gstaad, Switzerland, 2016.  The experience on skis may have come in handy in 2022 during filming for Netflix's Falling for Christmas.

Slope was the domestic chaplain to Bishop Proudie at Barchester and began as a protégé of the Bishop’s wife (a truly ghastly woman) but later became her enemy as he attempted when he endeavored to wrest the control of the diocese from her hands by becoming an eminence (pâle) rouge, a kind of vicarage Richelieu controlling the Bishop.  The plots and schemes of the calculating chaplain, conducted with much obsequiousness, play out in the novel as a part of a struggle between those of the high church and the evangelicals, a struggle not resolved to this day.  The Trollope aficionados don’t regard Barchester Towers as his best work but few deny it’s one of the most enjoyable and anyone who wishes to sample Trollope should start here.

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 (ICE) of the mid-late twentieth century, especially as the availability of higher octane gas (petrol) made possible higher compression ratios, 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 unit possible with in-line arrangements and 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 what they named polyspheric (two shallow concave domes under the in-line valves) which, as a companion to the Hemi, quickly was nicknamed "“Poly”.  Although less powerful than the Hemis, the Polys, with  more quickly machined combustion chambers and a single rocker shaft, enjoyed significantly lower unit production costs so the economics were attractive although it wouldn’t be until the 1960s 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 Poly however proved a cul-de-sac.  In an era of cheap gas, larger capacity engines proved a more attractive route to horsepower than sophisticated combustion chamber design and the Hemis were retired in 1958, replaced by engines of larger displacement with wedge-shaped chambers, used by other manufacturers and much more suited to mass-production.  Consigned to the grave with the Hemi were almost all the Polys, only the 318 V8 (5.2 litre) retained as a rare oddity until 1967.  The Hemi would in 1964 return, available 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, remaining an expensive option in certain Dodges and Plymouths until 1971.  The name however held such an allure it was in 2003 revived in 2003 (although the corporation's Australian arm between 1970-1981 produced a straight-six "Hemi" (which was really a "semi-hemi")) for Chrysler's new (and perhaps final) generation of V8s.  Like the highly-regarded Australian engine, in the narrow technical sense, the use of "Hemi" for the new V8 (dubbed "Generation III to capitalize on the name's storied legacy") really was a marketing than an engineering term because the combustion chambers were something of a hemispheric cum polyspheric hybrid, the general term describing them for the last fifty-odd years being swirl chambers, a design which, in combination with modern electronic engine management systems (EMS), makes possible autput of power, low emissions and economy which would have been thought impossible to achieve as recently as the 1980s.

Street Muscle's helpful summary of the strange tale of the “318 Poly”; note the unusual arrangement in which the exhaust valve runs parallel to the bore while the intake valve is canted toward the intake manifold.

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 also as descendent)), the most obvious visual difference from the earlier A-Series V8s was the noticeably smaller cylinder heads.  The A engines used a 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 with a wedge combustion chamber.  The reason for the change was the decision had been taken to offer the compact (in contemporary US terms; it would have seemed pretty big in most of the planet) Valiant with a V8 but it 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 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 batches, 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-six 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 concoct.

Upon release in 1955, the Polyspheric V8s were thought such a novelty they generated much publicity, not only in trade or specialist publications but also in the mainstream press.  Although not yet the “space age”, it was already the “jet age” and there was genuine public fascination with apparently new or innovative products, even if many were really variations of something old and the advertising copy was sometimes the most adventurous aspect.  To help the journalists, included in Chrysler’s press-kits were full-color diagrams explain the theory, illustrating the unseen cycle of fluid dynamics happening under the hood (bonnet) thousands of times a second.  However pleasing the graphics, not all were impressed by the name, Motor Trend magazine in their February 1955 edition publishing a letter from a Mr Hal Julian of Los Angeles whose objection was the word “polyspherical” didn’t exist and what Chrysler should have used was “hemispheroid” (used variously to mean (1) having a roughly hemispheric shape and (2) half of a spheroid), definitions of the latter appearing in dictionaries.  However, while it may not have appeared in the shorter (abridged) dictionaries, polysphere (in mathematics & geometry “a product of spheres”) did have entries in both supplements to the twelve volume Oxford English Dictionary (1933) and Webster's New International Dictionary (1934) which weighed in with over 600,000 words and was an impressive eight-odd inches (200 mm) thick.

Escher (1898–1972).  The final engraving (left) may be compared with the pencil on paper study (right).  This was one of a number of works in which Escher explored how, with the greatest precision, a three-dimensional form could be represented on a flat surface.

Polyspherical seems first to have appeared in print in the 1920s in papers published by British physicist Sir Edmund Whittaker (1873–1956) and US physical chemist Gilbert Lewis (1875–1946), the latter remembered also for having in 1926 coined the word “photon” to describe the smallest unit of radiant energy.  The two both used “polyspherical” in the context of what they termed “polyspherical coordinates”, used as devices to solve puzzles in partial differential equations in higher-dimensional spaces, an arcane field understood, even now, only by a few although most of us benefit from the implications.  It’s a fork of the discipline replete with terms baffling to most but the experts note “polyspherical coordinates” by the mid-1930s became formalized in its use to refer to systems “generalizing spherical coordinates to higher dimensions using nested angular parametrizations”.  Sounds simple enough.

Pre 1000: Middle English pile from Old English pīl (shaft) derived from the Latin pīlum (javelin) and pīla (pillar or mole of stone).  Variations emerged in Late Middle English, pyles from 1375–1425 was a plural of the Latin pilae (literally, balls) and from 1300–50 piles (hair, plumage) from the Latin pilus (hair), the -i- short in Latin but long in Anglicized school pronunciation.  The Middle English pyl (reverse of a coin) was a special use of the Medieval Latin pīla.  Word actually passed to English from the Old French pyle. 

The meaning "mass or heap" was universal by the early fifteenth century, originally "pillar, pier of a bridge," from Middle French pile and directly from Latin pila "stone barrier, pillar, pier"; the development in Latin from "pier, harbor wall of stones," to "something heaped up" and the meaning "large building", common by the fourteenth century is probably the same word.  The "heavy pointed beam" is from the Old English pil (stake), as "arrow" is from the Latin pilum (heavy javelin of the Roman foot soldier, literally pestle), source of the Old Norse pila, the Old High German pfil, and the German pfeil (arrow).  Of all these, origin is uncertain.  The meanings as applied to fabrics and downy plumage are from the Anglo-French pyle or the Middle Dutch pijl, both from Latin pilus (a hair), source of the Italian pelo and Old French pel.  Phonological evidence rules out transmission of the English word via the Old French cognate peil and poil; meaning "nap upon cloth" emerged in the 1560s.  The most familiar modern meeting (to heap up) is from the mid fourteenth century while the figurative verbal expression “pile on” (attack vigorously, attack en masse) is an Americanism from 1894.

Chicago Pile-1

The atomic pile was the original name for a nuclear reactor, a device used to initiate and control a self-sustained nuclear chain reaction.  Chicago Pile-1 (CP-1) was the world's first nuclear reactor and on 2 December 1942, the first human-made self-sustaining nuclear chain reaction was initiated.

Chicago Pile-1, 1942                          

CP-1 was built with 45,000 graphite blocks weighing 360 tons used as neutron moderators, fueled by 5 tons of uranium metal and 45 tons of uranium oxide which, despite the bulk, produced only a tiny amount of power, about one-half watt. The original design intended the shape to be spherical but, during construction, it was calculated the critical mass required for a chain-reaction could be achieved with a smaller pile.  Disassembled in 1943, CP-1 was reconfigured to become Chicago Pile-2 (CP-2) and it operated in that form until 1954 when it was dismantled and buried.

The term "atomic pile" is a historic artefact from the early years of the science but essentially they were the first nuclear reactors, the term derived from what the physicists at the time visualized as a "pile" of the graphite blocks used to moderate the nuclear reaction.  Why the word "pile" was chosen as a descriptor doesn't seem to have been recorded but it must at the time have seen an obvious choice although, the convention in English would have been to use "stack" because although "pile" and "stack" both refer to agglomerations of objects (although can figuratively also be used of the non-physical), the two have slightly different connotations.  A pile tends to be an unordered heap of items, placed without much care to produce a random or shape ("pile of clothes on the floor", "pile of leaves in the yard" etc).  By contrast, a stack is a more orderly arrangement of items placed atop each other ("stack of books on a table", "stack of plates in a cupboard" etc), suggesting something and structured (although the stuff in the stack could in some ways be quite haphazard (ie not in alphabetical order etc).   So, a pile tends to appear to be disordered or unstructured, while a stack suggest some sense of deliberate organization.  None of that suggest the early, pioneering theorists and researchers were wrong in their choice of word.  The first nuclear reactors were called a pile to reflect the basic, rather unrefined way the components were "piled together"; these really were scientific experiments and not without risk, a number of scientists and engineers who worked in close proximity to Chicago Pile-1 dying prematurely from internal cancers, including Italian-American physicist Enrico Fermi (1901–1954), the device's designer & builder.
