Bulge

Bulge (pronounced buhlj)

(1) A rounded projection, bend or protruding part; protuberance; hump; to swell or bend outward; to be protuberant.

(2) Any sudden increase, as of numbers, often used in economics or demography.

(3) In the maritime sciences, a rising in small waves on the surface of a body of water, caused by the action of a fish or fishes in pursuit of food underwater.

(4) As bulging, to describe a box or similar container, the shape of which is distorted by being filled beyond its nominal capacity.

(5) In colloquial use, the outline of male genitals visible through clothing, a form especially popular in the states & micro-states of Melanesia and used also (by analogy with the bulge caused by a wallet) as a descriptor of wealth.

1200-1250: From the Middle English bulge (leather bag; hump), from the Old Northern French boulge & bouge (leather bag), from the Late Latin bulga (leather sack), from the Gaulish bulga & bulgos, from the Proto-Celtic bolgos (sack, bag, stomach).  It was cognate with the various English forms bilge, belly, bellows & budget, the French bouge, the Irish bolg (bag) and the German Balg; a doublet of budge.  Ultimate source was the primitive Indo-European bhelgh (to swell), an extended form of the root bhel (to blow, swell).  The sense of "a swelling, a rounded protuberance" is first recorded in the 1620s and it’s likely the later bilge is a nautical variant.  The later, more familiar military meaning "bulging part of a military front" was first noted in 1916, the Admiralty variation to refer to the shape a warship’s hull assumed after the addition of anti-torpedo armor appearing in the records of naval architects a year later.  The famous phrase "battle of the bulge" has been re-purposed by the weight-loss industry.  Synonyms and related words include wart, lump, nodule, protrude, swell, sag, bloat, projection, bump, swelling, promontory, growth, excrescence, dilation, bunch, protrusion, salient, hump, sac & blob.  Bulge, bulger & bulginess are nouns, bulging & bulgy are adjectives, bulged is a verb and bulgingly is an adverb; the noun plural is bulges.

Increasing bulginess: Lindsay Lohan's baby bump.  English phrases emerge organically and women seem much to prefer "baby bump" to "baby bulge", a Google search for the former returning 33,300,000 hits against a mere 35,000 for the latter.  "Baby bulge" does however have (usually unwanted) role in the process, the "postpartum baby bulge" a description of an abdomen which stubbornly resists post-delivery inducements to return to it's pre-pregnancy shape.

The hood (bonnet) bulge

1957 Jaguar XKSS (left), 1955 Mercedes-Benz 300 SLR (W196S) Uhlenhaut coupé) (centre) and Mercedes-Benz 300 SL (W198, 1954-1963, right).

A hood (bonnet) bulge differs from a hood scoop in that the former exists purely for the purpose of providing clearance for some piece of machinery beneath.  What needs to be accommodated typically will be an inconveniently tall part of the engine, a supercharger or some other component in the induction system.  Jaguar added a bulge to the D-Type (1954-1957) because after lowering the profile of the hood in the quest for aerodynamic efficiency, the XK-six wouldn't quite fit, even with the addition of a dry sump which gained a few inches.  The bulge was carried over to the XKSS, the road-going version of the D-Type.  On the Jaguars, the bulge was centrally placed but Mercedes-Benz, adopting the same expedient for the 300 SLRs needed theirs to exist on only one side where it also acted as an air-intake for the mechanical fuel-injection, an example of a bulge doing also some scooping.  Asymmetry is common on racing cars where function rules but the factory apparently couldn't in those days bring themselves to do it on road cars.  Although the 300 SLs (both the gullwings and the roadsters) needed only the bulge on the right-hard side (the tall, dry-sumped engine canted 50^o to the left) to accommodate the fuel-injection's ram-tubes, a matching bulge was included, thus ensuring the symmetry prized by the Germans.

Mercedes-Benz may have been disturbed by asymmetry but it didn't worry the pragmatists at MG who, having shoe-horned into the MGB (1962-1980) a big iron lump of a straight-six which necessitated using a torsion bar arrangement for the front suspension, found even their first attempt at a bulge still wasn't enough.  A dry sump would have solved the problem but that would have been expensive so a "blister" was added at the offending point on the bulge; a bulging bulge as it were.  Apparently a matching blister on the right was never considered and the MGC has one of the industry's more admired bonnets although that feeling didn't extend to the rest of the car, the model not even a modest success in the market and it lasted but two seasons.  The later V8 version (1973-1976) was both a better car and one that needed no bulge at all but it fell victim to the first oil shock.  There are those who claim the rectilinear protrusion on the hood of the big-block Iso Grifos can't be called a bulge at all and many etymologists might agree but such pedantry should be agreed with and ignored.  Nicknamed the "penthouse", the neo-brutalist construction is one of the industry's great bulges and it's entirely functional, affording clearance to the induction system and providing airflow, in & out.  Not functional at all was the bulge Ford in Australia added to the XR8 Falcons when the BA model was released in 2002.  Cheerfully admitting it was unnecessary and there just for looks, the factory later took advantage of its presence to advertise things like the V8's power output, a juvenile pleasure much appreciated by the target market.

Battle of the Bulge, December 1944-January 1945

The Ardennes Offensive, (Wacht am Rhein (Watch on the Rhine) was the German code-name) popularly known in the West as the Battle of the Bulge, was the last major German strategic offensive of World War II and ironically, Watch on the Rhine was the title of a play by Lillian Hellman (1905-1984) which debuted on Broadway in 1941, the theme being the need for an international alliance to oppose the Nazis.  After many delays, it began on 16 December 1944 and lasted officially until 25 January but had been repulsed by Allied forces weeks earlier.  It wasn't the first use of "bulge" in a battlefield context, the phrase documented in June 1940 in discussions about the German offensive in France and many generals over the centuries would have seen bulges represented on their situation maps.  One especially well-known One of the best known was Unternehmen Zitadelle (Operation Citadel), the German operation conducted in July 1943 against Soviet forces in the Kursk salient although, unlike the Ardennes Offensive, the Battle of Kursk was staged along a very long front and is best understood as a series of shifting bulges and the theatre evolved rapidly into a huge, dusty, swirling mass of tanks, artillery assaults and air attacks.  It remains history's largest tank battle.  

The bulge, December 1944.

Because of the disparity in military and economic strength between the German and Allied forces, in retrospect, the Ardennes Offensive appears nonsensical but, at the time, it made strategic and political sense.  Adolf Hitler (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945) knew, confronted as he was by attacks from the west, east and south, continuing to fight a defensive war could only delay the inevitable defeat.  An offensive in the east was impossible because of the strength of the Red Army and even a major battlefield victor in the south would have no strategic significance so it was only in the west that opportunities existed.

For many reasons, by late 1944 the Allied advance in the west had stalled after remarkable progress since the D-Day landings 6 June 1944) and defensive lines had been formed, the most lightly defended being those in the Ardennes Forest, the very region which had been the conduit for the German’s stunningly successful blitzkrieg campaign in 1940.  Despite that history, 1944’s rapid advance through collapsing German lines had convinced Allied intelligence their enemy was no longer capable of major offensive operations.  It was this compliancy which made the German attack possible and in military colleges this problem, created by what in the psychology literature is called "Bayesian perception" (from the probability theories developed by English statistician Thomas Bayes (circa 1700-1761)), is often more helpfully described as "top-down processing" which tends to overwhelm the inherently more accurate "bottom-up processing".  The idea is that a "Bayesian brain" will use prior knowledge and assumptions which will influence perceptions meaning we see what we expect to see and fail to observe what is not expected and the more intensely something is focused upon, the more acute becomes the tendency.  Thus, because the phrase "Paris in the spring" is so well known, a single glance will confirm the brain's perception and the duplicate "the" will remain unseen.

In the last great example of the professionalism and tactical improvisation which was a hallmark of their operations during the war, the Wehrmacht (the German military) secretly assembled a large armored force, essentially under the eyes of the Allies and staged a surprise attack through the Ardennes, aided immeasurably by the cover of heavy, low clouds which precluded both Allied reconnaissance and deployment of their overwhelming strength in air-power.  Hitler’s audacious strategic objective, which, given the forces available, none of his generals though possible, was to advance to the Belgium port of Antwerp, splitting the Allied lines in a pincer movement, destroying their four armies.  This he hoped would force the Western Allies out of the war, permitting the Germans to focus their entire strength against the Soviet Union in the east.  Initially successful, the Wehrmacht’s advance punched several holes in the line, the shape of which, when marked on a map, lent the campaign the name Battle of the Bulge.  Within days however, the weather cleared and the Allies were able to unleash almost unopposed their overwhelming superiority in air power.  This, combined with their vast military and logistical resources, doomed the Ardennes Offensive, inflicting losses from which the Wehrmacht never recovered.  From mid-January on, German forces never regained the initiative, retreating on all fronts until the inevitable defeat in May.

The IDF, Hamas and the Hezbollah, October 2023

Mr Netanyahu.  His friends, (both of them) call him "Bibi".

Already, comparisons with 1944 are being made with the apparent failure of the much vaunted Israeli intelligence machine, either to detect or act upon indications of the activities which would have been a prelude to the audacious attacks launched on 7 October 2023 by the Hamas into Israeli territory.  Although low-tech by comparison with a conventional military operation, the scale of what the Hamas managed to stage would still have demanded movements of materiel and personnel, an exercise in logistics which should have been noticed.  In an echo of the Yom Kippur War (6-25 October 1973), presumably, some activity would have been noticed but clearly it wasn't interpreted as an imminent threat so the inevitable review will have to focus on both the gathering and analysis of intelligence and one thing which will be considered is whether, as in the winter of 1944, assumptions were allowed to prevail over facts on the ground.  Any inquiry can be expected to be rigorous but only within the terms of reference the government will provide and those parameters are unlikely to allow any consideration of the consequences of the recent actions of Benjamin Netanyahu (b 1949; Israeli prime minister 1996-1999, 2009-2021 and since 2022).  Mr Netanyahu has for some time been attempting to make structural changes to Israel's courts, allegedly because he wishes to avoid any judicial scrutiny of the corruption charges which he faces.  The proposed changes to the courts are would actually align the way things are done in Israel with those used in many Western, democratic nations but it's the political context which has made them controversial and part of the widespread and long-lasting public protest has included large numbers of military reservists (on which the security of the Jewish state depends) refusing to serve while the government continues the legal manoeuvres which would have the effect of shielding the prime minister from prosecution.  Mr Netanyahu is one of the great survivors of modern politics and his longevity in office has been a remarkable achievement in one of the world's more difficult neighborhoods but it's unpredictable whether he can turn the shock of the Hamas incursion to his advantage and that is likely to depend upon managing any perception his being distracted by his own legal difficulties made Israel unusually vulnerable.

Securing any advantage will of course depend on Israel gaining what can be presented as a victory, something which in recent conflicts, north & south, has been as elusive on the battlefield as on social media.  Nor is the Hamas attack the only thing which will absorb the resources of the Israeli Defense Force (IDF).  In the north, there is the even more formidable Hezbollah and few in the intelligence community have cast doubt on reports the Shi'ite militia (which out-guns the armed forces of Lebanon and has more political influence) have some hundred-thousand short & medium range rockets available for deployment south of the Litani River (the Qasimiyeh or River Leontes).  Within hours of the Sunni Hamas launching their operation, the Hezbollah targeted Israeli military positions in the disputed Shebaa Farms, announcing it was acting "in solidarity" with the Palestinian people and in response, the IDF responded with artillery barrages.  No casualties were reported and at this stage the attack in the north seems to be thought a supportive gesture rather than anything strategic and the consensus is the Hezbollah will act at scale only if the situation in Gaza evolved to offer a particularly attractive opportunity and even then it would require approval from Tehran; in an unsubtle waring directed at the Ayatollahs, the Pentagon announced the movement of an aircraft carrier into the region.  The Hamas have seemingly timed their high-risk attack with some thought.  With the war in Ukraine demanding much military, political and financial support from the West (something already beginning to fray as Moscow predicted it would in any battle of attrition), the US government in political & fiscal paralysis and Israeli support for its own government at a historic low, the Hamas will have sniffed blood.  Nor will they be unaware the most long-lasting legacy of the Yom Kippur War fifty years earlier was the Arab oil embargo and the spike in the price which ended the long post-war prosperity in the West and triggered the political and economic upheavals which would last a decade.  The structure of the world economy and the imperatives of governments are not in 2023 quite what they were in 1973 but these things will be on the minds of many in many places.

In the short term, within the Israeli intelligence establishment, there will be an admission the military specialists will have to share more of the space with the political analysts.  With a death toll on both sides already in the thousands, the focus is of course on bullets and bombs but what Hamas has also done is stake their claim for support (1) in the region, (2) among the Arab & Palestinian diaspora and (3) from those governments willing to fund proxies for their campaigns against the West.  In this sense, the Hamas is advertising themselves as a muscular resistance to Israeli (ie Western) oppression and occupation, contrasting themselves with Fatah, the faction controlling the Palestinian Authority which exercises nominal authority over what is left of the Left Bank territories.  The Hamas regard Fatah as as least accommodative while some use the slur "collaborators".  Thus positioning the contrast as something like the Marquis vs Vichy, October's assault has a political aspect and in that they identified their target market rather as the Republican Party's "House Freedom Caucus" focused on those dissatisfied with the direction of their own leadership.

What Hamas are practicing is politics with a high civilian death toll, the rationale for that being every Palestinian who is killed will have died a martyr's death with all that implies, theologically and socially.  As a tactic, what Hamas are doing is a kind of political intervention into what they see as the increasingly disturbing trend of Arab nations moving towards normalization of relations with the state of Israel without any settlement of the "Palestinian problem".  If the IDF can be induced to respond with such severity that the civilian death toll in Gaza rises to the point where the pressure from the so called "Arab street" is of such intensity that Arab states are forced to retreat from their recent rapprochements, for Hamas, that would be progress.  There was a time when the strategists in Gaza might have imagined the regional reaction would be something more tangible on the ground but as they've noticed, winds of change can blow in both directions and now it's only in Tehran there's much support for their long-standing position that the only final solution for the Palestinians is the destruction of the state of Israel.

1250–1300: From the Middle English blister & blester (thin vesicle on the skin containing watery matter), possibly from the Old French blestre (blister, lump, bump), probably from the Middle Dutch blyster & bluyster (swelling; blister), from the Old Norse blǣstri (a blowing), dative of blāstr (swelling).  All the European forms are from the primitive Indo-European bhlei- (to blow, swell), an extension of the root bhel- (to blow, swell).  The verb emerged late in the fifteenth century in the sense of “to become covered in blisters” and the medical use (of vesicatories) meaning “to raise blisters on” is in the literature from the 1540s.  The noun & adjective vesicatory dates from the early eighteenth century was from the Modern Latin vesicularis, from vesicula (little blister), diminutive of vesica (bladder).  In historic medicine, a vesicant (plural vesicants) or vesicatory (plural vesicatories) is used as an agent which induces blistering.  Typically a chemical compound, the primary purpose was intentionally to create a blister to draw blood or other bodily fluids to the surface, often in an attempt to relieve inflammation, improve circulation in a specific area, or treat various conditions indirectly by this counter-irritation technique.  Historically, vesicatories were commonly used with substances like cantharidin (from blister beetles) being applied to the skin to achieve this effect but in modern medicine the practice is (mostly) obsolete because more effective and less invasive treatments now exist.  Blister & blistering are nouns, verbs & adjectives, blistered is a verb & adjective, and blisterlike, blisterless & blistery are adjectives; the noun plural is blisters.

1968 MGC Roadster with bulge, blister and the bulge's curious stainless steel trim.

The MGC (1967-1969) was created by replacing the MGB’s (1962-1980) 1.8 litre four cylinder engine with a 2.9 litre (178 cubic inch) straight-six, something which necessitated a number of changes, one of which was the bonnet (hood) which gained a bulge to accommodate the revised placement of the radiator and, on the left-hand side, a small blister because the forward of the two carburettors sat just a little too high to fit even with the bulge.  Because to raise the whole bulge would have the bonnet look absurd, the decision was taken just to add a blister.  A blister (in this context) is of course a type of bulge and where a blister ends a bulge begins is just a convention of use, blisters informally defined as being smaller and of a “blister-like shape”, something recalling one appearing on one’s foot after a day in tight, new shoes.  A blister (which some seem to insist on calling a “teardrop” in they happen to assume that shape) also differs from a scoop in that it’s a enclosed structure whereas a scoop has an aperture to permit airflow.  There are however some creations in the shape of a typical blister which are used for air-extraction (the aperture to the rear) but these tend to be called “air ducts” rather than blisters.  MGC’s bulged and blistered bonnet has always been admired (especially by students of asymmetry) and both the originals (in aluminium which is an attraction in itself) and reproduction items are often used by MGB owners, either just for the visual appeal or to provide greater space for those who have installed a V8.  The apparently superfluous stainless steel trim piece in the bulge (there's no seam to conceal) is believed to be a motif recalling the small grill which was in a similar place on BMC’s (British Motor Corporation) old Austin-Healey 3000 (1959-1967), the MGC created because the 3000 couldn’t easily be modified to comply with the increasingly onerous US regulations.  Because there were doubts the cost of developing a replacement would ever be recovered, the decision was taken to build what was, in effect, a six-cylinder MGB.  The considerable additional weight of the bigger engine spoiled the MGB’s almost perfect balance and although a genuine 120 mph (195 km/h) machine, the MGC was never a critical or commercial success with only 8,999 (4,542 roadsters & 4,457 coupés) produced during its brief, two season life.

Republic P-47C Thunderbolt with the original colonnaded canopy (top) and the later P-47D with blister canopy (bottom).

When the Republic P-47 Thunderbolt (1941-1945) entered service with the USAAF (United States Army Air Force) in 1942, it was the largest, heaviest, single seat, piston-engined fighter ever produced, a distinction it enjoys to this day.  However, one thing it did share with some of its contemporaries was the replacement in later versions of the colonnaded canopy over the cockpit by an all-enveloping single panoramic structure which afforded the pilot unparalleled visibility, something made possible by advances in injection molding to fabricate shapes in Perspex, then still a quite novel material.  These canopies were adopted also for later versions of the The Supermarine Spitfire (1938-1948) and the North American P-51 Mustang (1941-1946) but the historians of aviation seem never to have settled on a description, opinion divided between “bubble-top” and “blister top”.

In military aviation, “blister” is more familiar as a use to describe the transparent bulge (or dome) on the fuselage of an airplane, usually for purposes of observation or mounting a gun but used sometimes to house a rearward air extraction device.  However, because of other linguistic traditions in military design, the “blisters” used as gun mounting position were also described with other words, the use sometimes a little “loose”.  One term was barbette (plural barbettes), a borrowing from the French and used historically to mean (1) a mound of earth or a platform in a fortification, on which guns are mounted to fire over the parapet and (2) (in naval use), the inside fixed trunk of a warship's gun-mounting, on which the turret revolves and used to contain the hoists for shells and cordite from the shell-room and magazine.

Meme-makers know whatever the advantages conferred by blister-packs, getting to the tablet can take a vital second or two.  Imodium is a medication used to treat occasional diarrhea.

Also used was turret, from the Middle English touret, from the Old French torete (which endures in Modern French as tourette), a diminutive of tour (tower), from the Latin turris.  In architecture (and later adoptions like electronic circuitry and railcar design), turrets tended to be variations of or analogous with “towers” but in military use there was a specific evolution.  The early military turrets were “siege towers”, effectively a “proto-tank” or APC (armoured personnel carrier) in the form of what was essentially a “building on wheels”, used to carry ladders, casting bridges, weapons and soldiers equipped with the tools and devices need to storm so fortified structure such as a fort or castle.  From this evolved the still current idea notion of an armoured, rotating gun installation on a fort or warship and as powered land vehicles and later flying machines (aircraft) were developed, the term was adopted for their various forms of specialized gun mountings.  In aircraft, the term blister came later, and allusion to the blister-like shape increasingly used to optimize aerodynamic efficiency, something of little concern to admiralties.

Mar-a-Lago, Ocean Boulevard, Palm Beach, Florida.

Another military blister was the cupola (plural cupolas or cupolae), from the Italian cupola, from the Late Latin cūpula (a small cask; a little tub), from the Classical Latin cuppella, from cuppa & cūpa (tub), from the Ancient Greek κύπελλον (kúpellon) (small cup), the construct being cūp(a) + -ula, from the primitive Indo-European -dlom (the instrumental suffix) and used as a noun suffix denoting an instrument.  The origin in Latin was based on the resemblance to an upturned cup, hence the use to describe the rounded top of just about any structure where no specific descriptor existed.  In military use, a cupola is basically a helmet fixed in place and that may be on a building, a ship or an armored vehicle, the function being to protect the head while offering a field of view.  Sometimes, especially in tanks or armored cars, guns or flame-throwers were integrated into cupolas and in naval gunnery, there was the special use to describe the dome-like structures protecting a (usually single) gun mounting, something which distinguished them from the larger, flatter constructions which fulfilled the same purpose for multi-gun batteries.  Turrets and cupolas are among the architectural features of Mar-a-Lago, Donald Trump’s (b 1946; US president 2017-2021) winter palace on Ocean Boulevard, Palm Beach, Florida.

Northrop P-61 Black Widow:  A prototype with the troublesome dorsal blister turret (left), the early production P-61A with the blister removed (upper right) and the later P-61B with the blister restored (lower right).

The attractive aerodynamic properties of the classic blister shape was an obvious choice for use in aircraft but even then, they weren’t a complete solution.  The Northrop P-61 Black Widow was the first aircraft designed from a clean sheet of paper as a night-fighter, cognizant of the experience of the RAF (Royal Air Force) which during the Luftwaffe’s (the German air force) Blitz of London (1940-1941) had pressed into service day-fighter interceptors.  Designed to accommodate on-board radar, the Black Widow was heavily gunned and incorporated notable US innovations such as remote control firing mechanisms.  Part of the original was a remotely-controlled blister turret on the dorsal section which proved the shape’s aerodynamic properties worked only when pointed in the appropriate direction; when pointed at right-angles to the aircraft’s centre-line, the tail section between the twin-booms suffered severe buffeting.  Accordingly, the blister turret was deleted from the early production versions but the early experience of the military confirmed the need for additional firepower and after a re-design, it was restored to the slightly lengthened P-61B.  The integration of so many novel aspects of design meant the P-61 didn’t enter service until 1944 and, as the first of its breed, it was never a wholly satisfactory night-fighter but it was robust, had good handling characteristics and offered the advantage of being able to carry a heavy payload which meant it could operate as a nocturnal intruder with a lethal disposable load.  It was however in some ways a demanding airframe to operate, the manufacturer recommending that when fully-loaded in its heaviest configuration, a take-off run-up of 3 miles (4.8 km) was required.  Although its service in World War II (1939-1945) was limited, remarkably, like the de Havilland Mosquito (DH.98), the Black Widow was also a Cold War fighter, both in service until 1951-1952 because of a technology deficit which meant it wasn’t until then jet-powered night-fighters came into service.  The Black Widow was in 1949 (by then designated F-51), the first aircraft in service in the embryonic USADC (US Air Defense Command), formed to defend the country from any Soviet intrusion or attack.

Xanax (Alprazolam), a fast-acting benzodiazepine.  It is marketed as anti-anxiety medication and supplied in blister packs.

Lindsay Lohan released the track Xanax in 2019.  With a contribution from Finnish pop star Alma (Alma-Sofia Miettinen; b 1996), the accompanying music video was said to be “a compilation of vignettes of life”, Xanax reported as being inspired by Ms Lohan’s “personal life, including an ex-boyfriend and toxic friends”.  Structurally, Xanax was quoted as being based around "an interpolation of" Better Off Alone, by Dutch Eurodance-pop collective Alice Deejay, slowed to a Xanax-appropriate tempo.

1815–1825: The construct was peri + scope, a back formation from periscopic from the Ancient Greek periskopein (to look around).  Peri- was from the Ancient Greek περί (perí) (about, around) and was cognate with the primitive Indo-European via.  Scope was from the From Italian scopo (purpose), from the Latin scopus (target), from the Ancient Greek σκοπέω (skopéō) & σκοπός (skopós) (examine, inspect, look to or into, consider), from σκέπτομαι (sképtomai), from the primitive Indo-European speḱ- and etymologically related to both skeptic and spectrum.  Periscope is a noun (and a largely archaic verb), periscopic is an adjective and periscopically an adverb.  The present participle is periscoping and the past participle periscoped); the noun plural is periscopes.

Periscope concepts using mirrors and lens.

Although variations of the device had existed for decades, the word periscope either wasn’t used or was at least not in general use before 1899 but as early as 1865 it attested as a technical term in photography.  The concept of the periscope (then called the polemoscope) and using two angled lens had been described as early a 1647 in a work discussing the geological nature of the moon although then it was envisaged as device suitable for military observation.  Undocumented and undated sketches thought to date from decades earlier have also been unearthed but, although conceptually accurate, their exact purpose is unclear and they may have been architectural drawings.

The first naval periscopes appeared in 1854, constructed by placing two mirrors in a vertical tube, fixed at each end at a 45° angle and were a noted feature of the early submarines used in the US Civil War (1861-1865); by the dawn of the twentieth century they’d begun regularly to be part of the design although the great innovation was the retractable periscope in 1902, then known as the skalomniscope or omniscope.  The retractable periscope quickly became a standard fitting to submarines and proved an important factor in the success they enjoyed during the First World War.

Surprisingly, given how simple the adaptation would have been, periscopes were little-used by nineteenth century armies but proved to be an invaluable addition to the kit in the trench warfare of 1914-1918, providing a wide vista for observation without exposing the viewer to the risk of attracting sniper fire.  One invention which proved of less utility was the so-called periscope-rifle, a kind of remote-controlled infantry rifle mounted atop the trench parapet, aimed and fired by a soldier in a safe position below.  Success was limited.  More useful were devices called stereoscopic rangefinders, periscopic binoculars with grids which enabled trained observers to estimate the distance to a target.

The Lamborghini Countach "Periscopio"

1971 Lamborghini Countach LP500 concept (note periscopio bulge in the centre of roof).

When shown at the 1961 Geneva Motor Show, the Jaguar E-Type (XKE) created a sensation.  At the same event, ten years later, the Lamborghini Countach LP500 created almost as much excitement and its lines have been the template for most Lamborghinis since.  In a sense, progress in the design of such machines paused at that point, everything since (and not just by Lamborghini) a refinement of the yellow wedge.  Although it was a small and functionally unsatisfactory aspect of the dramatic LP500, it was the abortive periscopio (periscope) which would be used to characterize the first 157 (some sources insist 158) LP400 production cars, the periscopio rear view concept lending the roof its distinct shape.  The factory’s documents don’t reveal whether the idea of the periscope was the inspiration of an individual or emerged from a committee but the thought was that in such a low-slung vehicle, the driver would be afforded a better view from a lens mounted atop the roof than would be provided by a conventional rear-view mirror aligned with the rear-window.  Donnelly Corporation in the US delivered a working version of the periscope mirror system, a number of which had actually be built in the era for use in the ESV (Experimental Safety Vehicle) projects which a number of manufacturers had developed to test their implementation of the engineering which would be required to conform with the safety regulations soon to come into force.

However, during testing, it became obvious it was not a desirable solution, the positioning dictated by the then unique profile requiring the driver too often to avert their eyes from what was ahead adequately to focus on what lay behind.  Nor did the designers warm to the small bulge which would have to be added to the roofline to accommodate the hardware; aesthetics meant little to those who penned ESVs but they were prized by Italian stylists and consequently the periscope was abandoned.  However, whether for reasons of economy or constraints of time, although the bulge was deleted, the remaining periscopio roof shape was retained and in 1974 entered production as part of the LP400 although it now provided no obvious functional advantage except making the cabin a little brighter and perhaps adding some rigidity to the structure although there may have been some aerodynamic cost, the interruption to what would otherwise be a smooth surface presumably generating additional drag.  Whatever the drawbacks however, stylistically, it’s always been admired.

1977 Lamborghini Countach LP400.

Those first 157 LP400s were also the closest the production cars would be to the original, unadorned wedge which had made such an impact when displayed at the 1971 Geneva Motor Show as the Lamborghini LP500 concept.  That it was described as a concept was important because the LP500, although fully-functional, was no prototipo (prototype), and the uncompromising original could not without modification be transformed into a practical production car, hence the many scoops to ensure adequate cooling as well as the deletion of the periscope, changes to the construction method used for the frame, a reduced-capacity engine, the substitution of analogue instruments for the space-age electronica and some enlargement of the platform to make the thing more habitable.  Still, the LP400 was remarkably close to the startling original and tellingly, of all two-thousand odd which would in five generations be produced between 1974-1990, it would be the one with the best aerodynamics, the wings, flares and fat tyres added over the years all adding to drag.  If the smooth roof, introduced on the LP400 S in 1978, improved aerodynamics, it wasn’t enough to compensate.

The influential but short-lived service

The evolution of the internet since it began to assume its modern form (after the world wide web was “bolted on” in 1991, gaining something like critical mass around 1993) is characterized by a number of separate, parallel and sometimes intersecting threads and probably no application (although technically it was a service) was so emblematic of the trends than Periscope.  Periscope was created because someone found the then text-only Twitter (now X) compelling but was annoyed at having to go elsewhere look for video feeds relating to what was being tweeted.  The Periscope model was to take advantage of the ubiquity of (1) smartphones meaning high-definition video could, worldwide, be created by billions of users at a moment’s notice and (2) the increasing availability of bandwidth which made real-time streaming practical and what emerged was a system noted for its simplicity; a few taps and whatever one was filming was being streamed.

In the way corporations sometimes do things, Twitter bought Periscope even before the product’s official release and success was immediate, the service quickly among the most popular with support notably coming from legacy broadcasters including the BBC which used the system as a low-cost form of content dissemination; in effect what used to be an “outside broadcast van” (literally a truck packed with cameras and transmission equipment which, with staff and other overheads cost sometimes millions a year to run and could be in one place at a time) was suddenly in the pockets of every staff member.  It was also in the pockets of everyone else, some of who were entrepreneurial and before long, Periscope streams of live events (for which broadcasters and others had paid sometimes millions for exclusive rights) and content on screens (cinemas, televisions etc) were being packaged for profit, cannibalizing many pay-per-view (PPV) business models.  A flurry of takedown notices (a specialized form of a C&D (cease & desist letter) ensued.  Periscope however became a victim of its own success, its model quickly available in many other ways and its functionality was “folded into” Twitter, the service discontinued in March 2021, much of the (not legally challenged) legacy content remaining available on X to this day.

Zugzwang

Zugzwang (pronounced tsook-tsvahng)

(1) In chess, a situation in which a player is limited to moves that cost pieces or have a damaging positional effect.

(2) A situation in which, whatever is done, makes things worse (applied variously to sport, politics, battlefield engagements etc).

(3) A situation in which one is forced to act when one would prefer to remain passive and thus a synonym of the German compound noun Zugpflicht (the rule that a player cannot forgo a move).

(4) In game theory, a move which changes the outcome from win to loss.

Circa 1858 (1905 in English): A modern German compound, the construct being zug+zwang.  Zug (move) was from the Middle High German zuc & zug, from the Old High German zug ,from Proto-Germanic tugiz, an abstract noun belonging to the Proto-Germanic teuhaną, from the primitive Indo-European dewk (to pull, lead); it was cognate with the Dutch teug and the Old English tyge.  Zwang (compulsion; force; constraint; obligation) was from the Middle High German twanc, from the Old High German geduang.  It belongs to the verb zwingen and cognates include the Dutch dwang and the Swedish tvång.  The word is best understood as "compulsion to move" or, in the jargon of chess players: "Your turn to move and whatever you do it'll make things worse for you", thus the application to game theory, military strategy and politics where there's often a need to determine the "least worse option".  Zugzwang is a noun; the noun plural is Zugzwänge.  In English, derived forms such as zugzwanged, zugzwanging, zugzwangish, zugzwanger, zugzwangesque and zugzwangee are non-standard and used usually for humorous effect.

Chess and Game Theory

Endgame: Black's turn and Zugzwang! Daily Chess Musings depiction of the elegance of zugwang.

The first known use of Zugzwang in the German chess literature appears in 1858; the first appearance in English in 1905.  However, the concept of Zugzwang had been known and written about for centuries, the classic work being Italian chess player Alessandro Salvio's (circa 1575–circa 1640) study of endgames published in 1604 and he referenced Shatranj writings from the early ninth century, some thousand years before the first known use of the term.  Positions with Zugzwang are not rare in chess endgames, best known in the king-rook & king-pawn conjunctions.  Positions of reciprocal Zugzwang are important in the analysis of endgames but although the concept is easily demonstrated and understood, that's true only of the "simple Zugzwang" and the so-called "sequential Zugzwang" will typically be a multi-move thing which demands an understanding of even dozens of permutations of possibilities.

Zugzwang describes a situation where one player is put at a disadvantage because they have to make a move although the player would prefer to pass and make no move. The fact the player must make a move means their position will be significantly weaker than the hypothetical one in which it is the opponent's turn to move. In game theory, it specifically means that it directly changes the outcome of the game from a win to a loss.  Chess textbooks often cite as the classic Zugzwang a match in Copenhagen in 1923; on that day the German Grandmaster (the title inaugurated in 1950) Friedrich Sämisch (1896–1975) played White against the Latvian-born Danish Aron Nimzowitsch (1886-1935).  Playing Black, Nimzowitsch didn’t play a tactical match in the conventional sense but instead applied positional advantage, gradually to limit his opponent’s options until, as endgame was reached, White was left with no move which didn’t worsen his position; whatever he choose would lead either to material loss or strategic collapse and it’s said in his notebook, Nimzowitsch concluded his entry on the match with “Zugzwang!”  A noted eccentric in a discipline where idiosyncratic behaviour is not unknown, the Polish Grandmaster Savielly Tartakower (1887-1956) observed of Nimzowitsch: “He pretends to be crazy in order to drive us all crazy.”

In its classic form chess is a game between two, played with fixed rules on a board with a known number of pieces (32) and squares (64).  Although a count of the possible permutations in a match would yield a very big number, in chess, the concept of Zugwang is simple and understood the same way by those playing black and white; information for both sides is complete and while the concept can find an expression both combinatorial game theory (CGT) and classical game theory, the paths can be different.  CGT and GT (the latter historically a tool of economic modelers and strategists in many fields) are both mathematical studies of games behaviour which can be imagined as “game-like” but differ in focus, assumptions, and applications.  In CGT the basic model (as in chess) is of a two-player deterministic game in which the moves alternate and luck or chance is not an element.  This compares GT in which there may be any number of players, moves may be simultaneous, the option exists not to move, information known to players may be incomplete (or asymmetric) and luck & chance exist among many variables (which can include all of Donald Rumsfeld’s (1932–2021: US defense secretary 1975-1977 & 2001-2006) helpful categories (known knowns, known unknowns, unknown unknowns & (most intriguingly) unknown knowns).  So, while CGT is a good device for deconstructing chess and such because such games are of finite duration and players focus exclusively on “winning” (and if need be switching to “avoiding defeat”), GT is a tool which can be applied to maximize advantage or utility in situations where a win/defeat dichotomy is either not sought or becomes impossible.  The difference then is that CGT envisages two players seeking to solve deterministic puzzle on a win/lose basis while GT is there to describes & analyse strategic interactions between & among rational actors, some or all of which may be operating with some degree of uncertainty.

In politics and military conflicts (a spectrum condition according to Prussian general and military theorist Carl von Clausewitz (1780–1831)), a zugzwang often is seen as parties are compelled to take their “least worst” option, even when circumstances dictate it would be better to “do nothing”.  However, the zugzwang can lie in the eye of the beholder and that why the unexpected Ardennes Offensive, (Wacht am Rhein (Watch on the Rhine) the German code-name though popularly known in the West as the Battle of the Bulge, (December 1944-January 1945)) was ordered by Adolf Hitler (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945).  It was the last major German strategic offensive of World War II (1939-1945) and among all but the most sycophantic of Hitler’s military advisors it was thought not “least worst” but rather “worse than the sensible” option (although not all the generals at the time concurred with what constituted “sensible”).  Under the Nazi state’s Führerprinzip (leader principle) the concept was that in any institutional structure authority was vested in the designated leader and that meant ultimately Hitler’s rule was a personal dictatorship (although the extent of the fragmentation wasn’t understood until after the war) so while the generals could warn, counsel & advise, ultimately decisions were based on the Führer’s will, thus the Ardennes Offensive.

While the operation made no strategic sense to the conventionally-schooled generals, to Hitler it was compelling because the tide of the war had forced him to pursue the only strategy left: delay what appeared an inevitable defeat in the hope the (real but still suppressed) political tensions between his opponents would sunder their alliance, allowing him to direct his resources against one front rather than three (four if the battle in the skies was considered a distinct theatre as many historians argue).  Like Charles Dickens’ (1812–1870) Mr Micawber in David Copperfield (1849-1850), Hitler was hoping “something would turn up”.  Because of the disparity in military and economic strength between the German and Allied forces, in retrospect, the Ardennes Offensive appears nonsensical but, at the time, it was a rational tactic even if the strategy of “delay” was flawed.  Confronted as he was by attacks from the west, east and south, continuing to fight a defensive war would lead only to an inevitable defeat; an offensive in the east was impossible because of the strength of the Red Army and even a major battlefield victor in the south would have no strategic significance so it was only in the west a glimmer of success seemed to beckon.

The bulge.

In the last great example of the professionalism and tactical improvisation which was a hallmark of their operations during the war, secretly the Wehrmacht (the German military) assembled a large armored force (essentially under the eyes of the Allies) and staged a surprise attack through the Ardennes, aided immeasurably by the cover of heavy, low clouds which precluded both Allied reconnaissance and deployment of their overwhelming strength in air-power.  Initially successful, the advance punched several holes in the line, the shape of which, when marked on a map, lent the campaign the name “Battle of the Bulge” but within days the weather cleared, allowing the Allies to unleash almost unopposed their overwhelming superiority in air power.  This, combined with their vast military and logistical resources, doomed the Ardennes Offensive, inflicting losses from which the Wehrmacht never recovered: From mid-January on, German forces never regained the initiative, retreating on all fronts until the inevitable defeat in May.  A last throw of the dice, the offensive both failed and squandered precious (and often irreplaceable) resources badly needed elsewhere.  By December 1944, Hitler had been confronted with a zugzwang (of his own making) and while whatever he did would have made Germany’s position worse, at least arguably, the Ardennes Offensive was not even his “least worse” option.
