Mach

Mach (pronounced mak, mahk or moch)

A number indicating the ratio of the speed of an object to the speed of sound in the medium through which the object is moving.  Also known as the Mach number; standard abbreviation is M.

1937: Named after Austrian physicist and philosopher Dr Ernst Waldfried Josef Wenzel Mach (1838–1916) who devised the system of speed measurement based on the Mach number. He’s remembered also as the founder of logical positivism, asserting the validity of a scientific law is proved only after empirical testing.  The Mach number is important in the understanding of fluid dynamics and represents the ratio of flow velocity past a boundary to the local speed of sound (Mach 1.0).  It’s most applied to aircraft which are classified:

Subsonic      Mach <1.0
Transonic     Mach =1.0
Supersonic   Mach >1.0
Hypersonic   Mach >5.0

The speed of sound varies, reducing at higher altitudes and if aircraft exceed about 250 mph (400 km/h), air near the aircraft is disturbed, locally changing the density.  This compression, increasing with speed, alters the force on the aircraft and is of great importance to aerodynamicists and structural engineers.  The Mach number is within the science of fluid dynamics because air is fluid and, at hypersonic speeds, the energy of the airframe affects the chemical bonds which hold together the nitrogen and oxygen molecules of air, the heated atmosphere becoming an ionized plasma of gas.  That’s why spacecraft re-entering earth’s atmosphere need to be insulated from high temperatures.  Mach 1 was first exceeded by an aircraft in level flight in 1947 but man-made objects travelling at that speed had long-existed, even before modern ballistics.  The crack of a whip is actually the sonic boom caused by the tip exceeding Mach 1.

The 1969 Ford Mustang Mach 1

Unlike Ford’s later Boss 302 and Boss 429 Mustangs, both powered by genuine racing engines, 1969’s outwardly similar Mustang Mach 1 was a less ambitious machine for street and strip and available with a variety of engines, one of which, thanks to a little Dearborn mendacity, was very competitive in the then highly popular sport of pro-stock drag-racing.  A moniker like Mach 1 is known in contract law as mere puffery, the notion being that in advertising it's possible to assert things which (1) can be neither proven nor disproven or (2), are so absurd no reasonable person would take them seriously.  In 1969 nobody took literally the idea a Mustang could break the speed of sound which was just as well because, at ground level, Mach 1 is 767 mph (1235 km/h) while the top speed of the most powerful Mustang Mach 1 was about 130 mph (210 km/h) or Mach 0.171.  Actually, most were built for drag-racing and geared for acceleration rather than top-end speed so few were capable of more than 115 mph (185 km/h) or Mach 0.151.

1969 Ford Mustang Mach 1 with 428 (FE Series) CobraJet V8.

Hankering for a seven litre (427 cubic inch) version, Ford had added their 427 V8 (FE Series) to the Mustang’s option list for 1968 but none were built (although Shelby did one (or two depending on how such things are counted) and an uncertain number were fitted by dealers pursuant to customer request.  Probably now most remembered from service in the Ford GT40 and the AC Shelby Cobra, the 427 was a famously powerful and robust unit, a trophy winner on circuits from Daytona to Le Mans but was also cantankerous, noisy, an oil-burner and, perhaps most importantly for Ford, expensive to build because of its complex lubrication and cylinder width at the extreme limit of the block’s capacity.  It had also reached the end of its development so, until their new Boss 429 V8 (385 series) became available, Ford hotted-up the previously unremarkable 428 V8 (FE), used until then smoothly to propel big luxury cars like the Thunderbird and LTD.  Pleasingly for Ford, the 428 developed for the Mach 1 gained its increased output from bolt-on bits and pieces and was cheap to produce.

1969 Ford Mustang Mach 1 with 351 (Windsor Series) V8.

Belying its dramatic appearance, the nose-heavy 428 Mach 1 was actually pretty bad at just about everything except the straight-line, quarter-mile sprints at which it excelled though Ford cheated to achieve even these 400 metre-long successes.  Upon its debut in 1968, the National Hot Rod Association (drag-racing’s sanctioning body) allocated vehicles to competition classes on the basis of manufacturers’ declared power-outputs.  Ford claimed the new 428 CobraJet generated 335 horsepower which was quite an understatement, something which allowed it to dominate that year’s national championships.  After that, the authorities cracked down and used their own assessments but by then the 428 CobraJet had done its job and such was the glow of the reflected glory that Ford sold over 70,000 Mach 1 Mustangs in 1969.  Not all were equipped with the big block 428 (a 390 cubic inch (6.5 litre) FE was also available which was about as heavy as the 428 but less powerful) and as road cars, those fitted with the small block (Windsor) 351 cubic inch (5.8 litre) V8 were probably more suited to what most people did most of the time.  Ford produced the Mustang Mach 1 between 1969 and 1978 although the 1974-1978 models are not well regarded, the name revived in 2003-2004 for a small production run and in 2021 the Mach 1 returned to the Mustang range.

Thrust SST, Nevada, 1997.

Almost fifty years to the day after US Air Force (USAF) pilot Chuck Yeager (1923-2020), flying a rocket-powered Bell X-1 aircraft, broke the sound barrier in Earth's atmosphere, RAF Pilot Andy Green (b 1962) set the absolute land speed record (LSR) driving the Thrust SST to a speed of 763.035 mph (1,227.985 km/h) over the stipulated flying mile (1.6 km).  It was the first time a land vehicle officially broke the sound barrier.  Powered by two afterburning Rolls-Royce Spey turbofan engines (the same type used by the British version of the F-4 Phantom II jet fighter) developing a net thrust of some 50,000 lb/f (223 kN) which equates to something in excess of 100,000 bhp (76 MW), the Thrust SST's record still stands.  Weighing a impressive 10 tons, at full throttle the fuel burn-rate was some 4.0 gallons (4.8 US gallons; 18 litres) per second or a tiny fraction of a mile per gallon.  Under the LSR rules mandated by the World Motor Sport Council, for a record officially to be sanctioned, there must be two runs in opposite directions within a certain elapsed time and the council confirmed the speed of sound was exceeded on both runs on 15 October 1997 at Black Rock Desert, Nevada (USA).

Machboos

Lindsay Lohan in an interview published in the November 2022 edition of Cosmopolitan magazine revealed her favorite Middle-Eastern dish to cook was machboos, part of Arab cuisine throughout the region and prepared almost always with chicken with rice and vegetables.  A kind of blend of biryani and risotto, the rice is cooked in the spiced broth of the meat or chicken, melding the spices and ingredients.  Rice is a core component of Arabic cooking and interestingly, in Arabic it’s known as ruz but in the Khaleeji dialect it is aish (life) while in Egyptian Arabic, aish refers to bread, an indication of its centrality to the diet.  Like hummus, between nations (and even families) in the Middle East, there’s often disagreement about how machboos should be prepared, most of the arguments revolving around the bzar (the spice mix) but it’s certainly adaptable, able to be served with achaar (mango or lime pickle), daqoos (a spicy tomato sauce), or yoghurt with chopped cucumber and mint.

Ingredients (for serving 4-6) (from Table Tales: Exploring Culinary Diversity in Abu Dhabi (Rizzoli)).

6 tablespoons plain yogurt, divided
2 tablespoons Emirati bzar spice mix, divided
1½ kg chicken, cut into pieces
500 g basmati rice
80 mls vegetable oil
5 cardamom pods, crushed
1 cinnamon stick
10 black peppercorns
2 whole lumi, cracked
450 grams onions, chopped
1 tablespoon ginger, crushed
1 tablespoon garlic, crushed
4 small green chilies, halved
1 teaspoon turmeric
1 teaspoon cumin
1 teaspoon coriander powder
285 grams canned tomatoes, chopped
1 teaspoon salt
Cooking oil as required
450 grams potatoes, peeled and cubed
Handful of fresh coriander, chopped

Garnish

3 tablespoons cooking oil
2 onions, thinly sliced
85 grams raw cashews
55 grams raisins
Fresh coriander, chopped

Instructions

(1) Combine 4 tablespoons of yoghurt with 1 tablespoon of the bzar in a large bowl.  Coat the chicken and then marinade for 1 hour or longer.  Rinse the rice and soak in enough water to cover for 1 hour; drain.

(2) Heat the oil in a Dutch oven over medium heat. Add the cardamom pods, cinnamon stick, peppercorns and lumi and stir for 2 minutes.  Add the onions and sauté until golden.  Add ginger, garlic, and green chilies and stir for 2 minutes.

(3) Add the chicken and marinade and then cook for a few minutes on each side.  Sprinkle in the turmeric, the remaining bzar, cumin, and the coriander powder.

(4) Add the tomatoes, salt, and 2 cups of water; bring to a boil.  Cover, lower the heat, and simmer for 30 to 45 minutes, until the chicken is done.  Transfer the chicken to a roasting pan.

(5) Remove the cinnamon stick and lumi from the stock and discard.  Add the potatoes and fresh coriander and boil until the potatoes are just tender.  Adjust the stock to get a one-to-one ratio with the rice.  Stir in the remaining yoghurt until dissolved and then add the rice.  Seal the Dutch oven with aluminum foil, cover, and cook over low heat for 30 minutes until the rice is done.

(6) Turn on the oven broiler.  Brush the chicken with some oil and broil until golden.  Serve the rice on a platter with the chicken pieces on top.  Garnish with sautéed onions, cashews, raisins, and fresh coriander.

Garnish Instructions

(7) Place a large skillet over medium-high heat and add the oil and onions; sauté until they are dark brown, but not burnt.  Remove the onions with a slotted spoon and drain on paper towels.  Sauté the cashews in the same oil until golden brown.  Finally, add the raisins during the last few minutes to complete.

Parabola

Parabola (pronounced puh-rab-uh-luh)

(1) In geometry, a plane curve formed by the intersection of a right circular cone with a plane parallel to a generator of the cone; the set of points in a plane that are equidistant from a fixed line and a fixed point in the same plane or in a parallel plane. Equation: y2 = 2px or x2 = 2py.

(2) In rhetoric, the explicit drawing of a parallel between two essentially dissimilar things, especially with a moral or didactic purpose; a parable.

1570s: From the Modern Latin parabola, from the Late Greek παραβολή (parabolḗ) (a comparison; a setting alongside; parable (literally "a throwing beside" hence "a juxtaposition") so called by Apollonius of Perga circa 210 BC because it is produced by "application" of a given area to a given straight line.  The Greek parabolḗ was derived from παραβάλλω (parabállō) (I set side by side”), from παρά (pará) (beside) + βάλλω (bállō) (I throw); a doublet of parable, parole, and palaver.  It had a different sense in Pythagorean geometry.  The adjectival form parabolic (figurative, allegorical, of or pertaining to a parable) from the Medieval Latin parabolicus from the Late Greek parabolikos (figurative) from parabolē (comparison) is now probably the most widely used.  In geometry, in the sense of “pertaining to a parabola”, it’s been in use since 1702.  A parabola is a curve formed by the set of points in a plane that are all equally distant from both a given line (called the directrix) and a given point (called the focus) that is not on the line.  It’s best visualised as a shape consisting of a single bend and two lines going off to an infinite distance.

Monza

On the Monza banking: Maserati 250F (left), Ferrari F555 Supersqualo (centre) & Vanwall VW2 (right).

The Autodromo Nazionale di Monza (National Automobile Racetrack of Monza) is now the fastest circuit still used in Formula One, the highest recorded speed the 231.5 mph (372.6 km/h) attained during qualifying for the 2005 Italian Grand Prix by a McLaren-Mercedes MP4-20 (in qualifying trim) on the long straight between the Lesmo corners and the Variante del Rettifilo.  Built in 1922, the Italian Grand Prix has been held there every year since 1949 except in 1980 when the track was being modernised and it’s a wonder the track has survived the attention of the Fédération Internationale de l'Automobile (the FIA; the International Automobile Federation).  Once an admirable body, the FIA has in recent decades degenerated into international sport’s dopiest regulatory body and has for some yers attempted to make motorsport as slow, quiet and processional as possible, issues like diversity now apparently more important than quality of racing.  Set in the Royal Villa of Monza park and surrounded by forest, the complex is configured as three tracks: the 3.6 mile (5.8 kilometre) Grand Prix track, the 1.5 mile (2.4 kilometre) short circuit and the 2.6 mile (4.3 kilometre) high speed oval track with its famous steep bankings which was unused for decades left to fall into disrepair before it was restored in the 2010s.  The major features of the main Grand Prix track include the Curva Grande, the Curva di Lesmo, the Variante Ascari and the famous Curva Parabolica.

On the parabolica: 1966 Italian Grand Prix.

The Curva Parabolica (universally known as “the parabolica”) is the circuit’s signature corner, an increasing radius, long right-hand turn and the final corner before the main straight so the speed one can attain on the straight is determined essentially by the exit speed from the the parabolica; a perfect execution is thus essential for a quick lap.  Although in motorsport it’s common to discuss the lengths of straights, one notable statistic is that even at close to 150 mph (200 km/h) speed with with the fastest cars take the curve, to transit the the parabolica takes just over 7.6 seconds.  Improvements to both the cars and the circuit means it’s now a less dangerous place but many drivers have died in accidents at Monza, some on or approaching the parabolica including Wolfgang (Taffy) von Trips (1928–1961) and Jochen Rindt (1942-1970).  In 2021, the Monza authorities announced the parabolica officially would be renamed “Curva in honor of former Ferrari factory driver Michele Alboreto (1956-2001) who to date remains the last Italian driver to win a Formula One Grand Prix for Scuderia Ferrari.  It’s likely most will still refer to the curve as “the parabolica”.

Esurient

Esurient (pronounced ih-soo-r-ee-uhnt)

(1) The state of being hungry; greedy; voracious.

(2) One who is hungry.

1665–1675: A borrowing from the Latin ēsurient & ēsurientem, stem of ēsuriēns (hungering), present participle of ēsurīre (to be hungry; to hunger for something), from edere (to eat), the construct being ēsur- (hunger) + -ens (the Latin adjectival suffix which appeared in English as –ent (and –ant, –aunt etc) and in Old French as –ent).  The form ēsuriō was a desiderative verb from edō (to eat), ultimately from the primitive Indo-European hédti (to eat and from the root ed-) + -turiō (the suffix indicating a desire for an action).  English offers a goodly grab of alternatives including rapacious, ravenous, gluttonous, hoggish, insatiable, unappeasable, ravening, avaricious, avid and covetous.  Esurient is a noun & adjective, esurience & esuriency are nouns and esuriently is an adverb; the noun plural is esurients.

For word-nerds to note, a long vowel in the Proto-Italic edō from the primitive Indo-European hédti is illustrative of the application of Lachmann's law (a long-disputed phonological sound rule for Latin named after German philologist and critic Karl Lachmann (1793–1851)).  According to Lachmann, vowels in Latin lengthen before primitive (and the later proto-) Indo-European voiced stops which are followed by another (unvoiced) stop.  Given the paucity of documentary evidence, much work in this field is essentially educated guesswork and Lachmann’s conclusions were derived from analogy and the selective application of theory.  Not all in this highly specialized area of structural linguistics agreed and arguments percolated until an incendiary paper in 1965 assaulted analogy as an explanatory tool in historical linguistics, triggering a decade-long squabble.  This polemical episode appeared to suggest Lachmann had constructed a framework onto which extreme positions could be mapped, one wishing to attribute almost everything to analogy, the other, nothing.  With that, debate seemed to end and Lachmann’s law seems now noted less for what it was than for what it was not.

In memory of Tenuate Dospan

A seemingly permanent condition of late modernity is weight gain; the companion permanent desire being weight loss.  The human propensity to store fat was a product of natural selection, those who possessed the genes which passed on the traits more likely to achieve sexual maturity and thus be able to procreate.  Storing fat meant that in times of plenty, weight was gained which could be used as a source of energy in times of scarcity and for thousands of generations this was how almost all humans lived.  However, in so much of the world people now live in a permanent state of plenty and one in which that plenty (fats, salt & sugars) doesn’t have to be hunted, gathered or harvested.  Now, with only a minimal expenditure of energy, we take what we want from the shelf or, barely having to move from our chair, it’s delivered to our door.  In our sedentary lives we thus expend much less energy but our brains remain hard-wired to seek out the fats, salt & sugars which best enable the body to accumulate fat for the lean times.  Some call this the "curse of plenty".

For all but a few genetically unlucky souls, the theory of weight loss is simple: reduce energy intake and increase the energy burn.  For many reasons however the practices required to execute the theory can be difficult although much evidence does suggest that once started, exercise does become easier because (1) the brain rewards the body for doing it with what’s effectively a true “recreational drug”, (2) it becomes literally easier because weight-loss in itself reduces the energy required and (3) the psychological encouragement of success (some dieticians actually recommend scales with a digital read-out so progress can be measured in 100 gram (3½ oz) increments).  Still, even starting is clearly an obstacle which is why the pharmaceutical industry saw such potential in finding the means to reduce supply (food intake) if increasing demand (exercise) was just too hard.

Lindsay Lohan about to assuage her esurience.

For centuries physicians and apothecaries had been aware of the appetite suppressing qualities of various herbs and other preparations but these were usually seen as something undesirable and were often a side effect of the early medicines, many of which were of dubious benefit, some little short of poison.  Although the noun anorectic (a back formation from the adjective anorectic (anorectous an archaic form) appeared in the medical literature in the early nineteenth century, it was used to describe a patient suffering a loss of appetite; only later would it come to be applied to drugs, firstly those which induced the condition as a side-effect and later, those designed for purpose.  The adjective anorectic (characterized by want of appetite) appeared first in 1832 and was a coining of medical Latin, from the Ancient Greek ἀνόρεκτος (anórektos) (without appetite), the construct being ἀν- (an-) (not, without) + ὀρέγω (orégō) (a verbal adjective of oregein (to long for, desire) which was later to influence the word anorexia)).  The noun was first used in 1913.

Tenuate Dospan.  As an industry leader in promoting diversity, Merrell was years ahead in the use of plus-size models.

In the twentieth century, as modern chemistry emerged, anorectic drugs became available by accident as medical amphetamines reached the black market as stimulants, the side effects quickly noted.  Those side effects however were of little interest to the various military authorities which during World War II (1939-1945) made them available to troops by the million, their stimulant properties and the ability to keep soldiers alert and awake for days at a time functioning as an extraordinary force-multiplier.  Not for years was fully it understood just how significant was the supply of the amphetamine Pervitin in the Wehrmacht’s (the German armed forces (1935-1945)) extraordinary military successes in 1939-1941.  In the post-war years, various types of amphetamine were made commercially available as appetite suppressants and while effective, the side effects were of concern although many products remained available in the West well into the twenty-first century.  Probably the best known class of these was amfepramone (or diethylpropion) marketed most famously as Tenuate Dospan which was popular with (1) those who wanted to be thin and (2) those who wanted to stay awake longer than is usually recommended.  Tenuate Dospan usually achieved both.

The regulatory authorities however moved to ensure the supply of Tenuate Dospan and related preparations was restricted, the concern said to be about the side effects although in these matters the true motivations can sometimes be obscure.  In their place, the industry responded with appetite suppressants which essentially didn’t work (compared with the efficient Tennuate Dospan) but sold for two or three times the price which must have pleased some.  The interest in restricting esurience however continued and one of the latest generation is Liraglutide (sold under various the brand names including Victoza & Saxenda) which started life as an anti-diabetic medication, the appetite suppressing properties noted during clinical trials, rather as the side-effects of Viagra (sildenafil) came as a pleasing surprise to the manufacturer.  Being a injection, Liraglutide is harder to use than Tenuate Dospan (which was a daily pill) and users report there are both similarities and differences between the two.

Liraglutide (Saxenda).  The dose increases month by month.

On Tenuate Dospan, one’s appetite diminished rapidly but food still tasted much the same, only the desire for it declined and being an amphetamine, energy levels were elevated and there were the usual difficulties (sleeping, dryness in the mouth, mood swings).  Dieticians recommended combining Tenuate Dospan with a high quality diet (the usual fruit, vegetables, clear fluids etc).  By contrast, although Liraglutide users reported much the same loss of interest in food, they noted also some distaste for the foods they had once so enjoyed and a distinct lack of energy.  It’s still early in the life of Liraglutide but it certainly seems to work as an appetite suppressant although in the trials, the persistent problem of all such drugs was noted: as soon as the treatment ceased, the food cravings returned.  Liraglutide does what the manufacturer’s explanatory notes suggest it does: it is a drug which can be used to treat chronic obesity by achieving weight-loss over several months, during which a patient should seek to achieve a permanent lifestyle change (diet and exercise).  It does not undo thousands of generations of evolution.  The early literature at least hinted Liraglutide was intended for obese adolescents for whom no other weight loss programmes had proved effective but anecdotal evidence suggests adults are numerous among the early adopters.

Diligence

Diligence (pronounced dil-i-juhns or dee-lee-zhahns (French))

(1) Constant and earnest effort to accomplish what is undertaken; persistent exertion of body or mind.

(2) In law, expressed often as “due diligence” the extent of care and caution required of a person or entity in the relevant circumstances.

(3) In the law of Scotland, the process by which persons, lands, or effects are seized for debt; process for enforcing the attendance of witnesses or the production of writings.

(4) Care; caution (obsolete).

(5) A public stagecoach, especially of the small, fast type once used in France (archaic).

1300–1350: From the Middle English deligence (constant and earnest effort to accomplish what is undertaken), from the Old French dilligence (attention, care; haste, speed) and directly from the Latin dīligentia (carefulness, attentiveness), from diligentem (nominative dīligēns) (attentive, assiduous, careful), the present-participle adjective from diligere (single out, value highly, esteem, prize, love; aspire to, be content with, appreciate (originally “to pick out, select”), the construct being dis- (apart) + legere (choose, gather), from the primitive Indo-European root leg- (to collect, gather (with derivatives meaning "to speak (in the sense of “to pick out words”).  The meaning-shift was gradual and evolved from “love” through “attentiveness” to “carefulness” to “steady effort”.  The legal sense “attention and care due from a person in a given situation” dates from the 1620s.  A now probably extinct synonym was worksomeness.  The –ence suffix was a word-forming element attached to verbs to form abstract nouns of process or fact (convergence from converge), or of state or quality and was from the Middle English -ence, from the Old French -ence, from the Latin –entia & -antia (depending on the vowel in the stem word).  The Latin present-participle endings for verbs stems in -a- were distinguished from those in -i- and -e- and as the Old French evolved from Latin, these were leveled to -ance, but later French borrowings from Latin (some of them subsequently passed to English) used the appropriate Latin form of the ending, as did words borrowed by English directly from Latin, thus diligence, absence et al.  There was however little consistency, English gaining many words from French but from the sixteenth century the suffix –ence was selectively restored, such was the reverence for Latin.  In French, the word dates from the 1740s and was a shortened form of carosse de diligence (literally “coach of speed”).  The stage-coach sense should be pronounced as in French because use will be so rare it’ll be thought correct rather than an affectation though if preferred, the further truncation “dilly” was common.  Diligence is a noun, diligent is an adjective and diligently an adverb; the noun plural is diligences.

In commercial law, due diligence describes the comprehensive and systematic review of all aspects of a business, investment opportunity or legal matter before a transaction or decision is made.  The process involves an examination of all available information (including identifying what is not available) related to the subject, including financial statements, contracts, legal relationships, intellectual property, internal structures and such obligations which may exist.  The purpose of due diligence is to identify potential risks, liabilities, or opportunities associated with the matter to ensure that whatever decision is taken, is made with a full understanding of all matters.  The companion term, summary diligence, isn’t drawn from law but describes a similar but less extensive process; less detailed and less comprehensive review which is restricted usually to only the critical aspects of the matter.  Summary diligence is undertaken when it’s certain that even in a worst case scenario, losses will be minimal or outweighed by other advantages.

Due diligence is the investigation or exercise of care that a reasonable business or person is normally expected to take before entering into an agreement or contract with another party or an act with a certain standard of care.  Although the concept also exists as a legal obligation, it’s also used of the process undertaken in self-interest to ensure all relevant information is known an assessed, prior to a decision being taken.  As a legal device, proof of others having failed to have exercised due diligence can in some circumstances be used as a defence against allegations of inadequate (as opposed to misleading) disclosure.  Alternatively, against allegations of negligence, if one can establish that the threshold of “reasonable care” had been reached, a defence can also succeed even if the process was in some way incomplete.  In the US where formally it entered the language of commerce and law during the 1930s, it was originally merely an indicative description of the process of investigation before, via an adjectival career, becoming both noun and legal jargon.  Depending on what’s required and as a general principle the larger the quantity and the more complex the quality of information to be assessed then the greater resources will be required duly to be diligent but the principles are the same of any data set and many check-lists are available for box-ticking.  Depending on what’s involved, there may be a functional need to create dozens of sub-headings under the boxes but, within the bounds of fuzzy logic, most check lists suggest the categories are something like: (1) Financial, (2) Legal, (3) Tax, (4) Compliance and Regulatory (5) Commercial, (6) Human Resources, (7) Intellectual Property, (8) Information Technology, (9) Environmental & (10) Health and Safety.

Lights burning at a quarter to midnight: the company formerly known as Credit Suisse.

The classic example of the use of the due diligence process is in mergers & acquisitions (M&A) and probably in no M&A activity is it of more interest than in the financial services sector.  It was notable therefore that the process or arranging the “purchase” by Swiss bank UBS (the old Union Bank of Switzerland) of its erstwhile national competitor Credit Swisse (the old Schweizerische Kreditanstalt) appeared to be completed in the time that either institution would once have though inadequate were either contemplating acquiring a reasonably successful suburban dry-cleaning shop.  It was however a most unusual purchase which should more correctly be thought a takeover or absorption and the timing of the announcement was based not on the satisfactory completion of the due diligence process but the need to make an announcement before the markets opened the next Monday morning.  Despite all that, UBS certainly undertook an exercise in due diligence, dotting every i and crossing every t, once the Swiss government had made it clear they were making an offer the bank shouldn’t refuse.  UBS’s interest was less in the exact state of Credit Suisse’s books (something that would take even a big team at least weeks to determine) than in ensuring whatever losses subsequently were sustained, they would be underwritten by the Swiss exchequer and not the bank.  To ensure that, UBS would have ensured diligence was more due than usual.  So there’s somewhere a “secret protocol” to the UBS-Credit Suisse pact, presumably well protected in a Zürich vault and it’s likely to be a document the Swiss government will be unlikely to discuss, let alone publish.

Hank Paulson before the US Congress, 2008, "explaining" the bank bailouts at the start of the global financial crisis (GFC).

Whether whatever the Swiss government undertook can be characterised as something like un-due diligence (as opposed to undue diligence) might emerge in the months ahead as the true position of Credit Swisse unfolds because it may be even within the organisation, nobody can be certain how high the liabilities might go, the track derivatives can follow being among the more unpredictable in the world of gambling.  Still, the fear over that weekend was something like Hank Paulson (b 1946; US treasury secretary 2006-2009) had little trouble conveying to the congress in the wake of the failure of Lehman Brothers (1850-2008) and the same risk of “contagion” meant Bern really had little alternative that have the Swiss taxpayer assume responsibility for whatever is going to happen.  If that turns out to be effectively a very big credit default swap (CDF), the Schweizerische Nationalbank (SNB, the Swiss central bank) quantitatively may need to easy many Swiss francs.

Photo due diligence

There are two aspects to "photo due diligence".

(1) Ex ante (before the photograph is taken) due diligence is assessment of factors such as the background, the environment and (often especially) who else will appear in any photo.  This is of some importance to those for whom public image management is an important part of their career.  One would not wish to be photographed in the “wrong” surroundings or be seen with the “wrong” people.

(2) Ex post facto (after the photograph is taken but before release for publication) due diligence is really possible only when “embargo” arrangements exist with the photographer, something sometimes a condition imposed by event organizers.  When photographs needed to be processed from negatives this something sometimes difficult to enforce but in the digital era, unsuitable images can instantly be deleted.  Out in the wild, where the paparazzi roam, it’s a contractual arrangement between subject and photographer and there is some evidence of cooperation.

Photo due diligence failure: Tony Abbott (b 1957; Australian prime-minister 2013-2015) photographed (left) outside the Reject Shop, Canberra, Australia, June 2015.  There was some prescience in the image because some three months later, the Liberal Party ejected him as leader and thus from the prime-ministership.  In this case, the failure of due diligence was among those minders who arranged the photo-opportunity although it’s surprising Mr Abbott’s political antennae seems not to have been sensitive.

Photo due diligence success: Lindsay Lohan at Christian Siriano’s fashion show, New York City, February 2023.  This one could be used in a case study of how to tick the due diligence boxes: (1) prestige brand-name, (2) front-row seating, (3) an acceptable degree of ethnic diversity, (4) the show well attended & (5) ideal lighting for photography.

Melon

Melon (pronounced mel-uhn)

(1) Any of various plants of two cucurbitaceous vines (the gourd family) including the watermelon, muskmelon et al.  Variations include Genus Cucumis (various musk melons, including honeydew, cantaloupes, and horned melon); Genus Citrullus (watermelons and others); Genus Benincasa (winter melon); Genus Momordica (a bitter melon)

(2) The fruit of any of these plants.

(3) A color ranging between a medium crimson and a deep pink, noted for the orange tinge.

(4) In zoology, the visible upper portion of the head of a surfacing whale or dolphin, including the beak, eyes, and blowhole (a mass of adipose tissue used to focus and modulate vocalizations).

(5) In the slang of (mostly North American) financial markets, an especially large additional dividend (often in the form of stock) distributed to stockholders (often as “cut a melon”).

(6) By extension, any windfall of money to be divided among specified beneficiaries.

(7) In slang, the breasts of the human female (almost always in the plural).

(8) In slang, the head; the skull.

(9) In slang, a derogatory term for members of a green political party, or similar environmental groups (rare and mostly Australia & New Zealand).

1350–1400: From the Middle English meloun & melon (herbaceous, succulent trailing annual plant or its sweet, edible fruit), from the Old Portuguese (via the thirteenth century Old French melon) melon, from the Late Latin melonem & mēlōn- (stem of mēlō and a shortening of mēlopepō (the “gourd apple”, a large apple-shaped melon)), from the Ancient Greek μηλοπέπων (mēlopépōn) (large apple-shaped melon), the construct being μηλο (mêlo(n)) (apple) + πέπων (pépōn) (ripe), from πέπτω (péptō) (to ripen).  Confusingly for historians seeking to reconstruct the recipes of Antiquity the Latin melopeponem was a kind of pumpkin while the Greek mēlopepon (gourd-apple) was applied to several kinds of gourds bearing sweet fruit, the origin of that in the noun use of pépōn (ripe) distinguishing the fruit on the vine ready for harvest from those yet to ripen.  As a modifier, melon is appended as appropriate (based on color, shape, diet, environmental niche, habitat etc) including melon beetle, melon cactus, Melon rugose mosaic virus, melon thistle & melon-headed.  The best known is probably the watermelon, dating from the 1610s and so named for their high content of water-like juice.  The more pleasing term in French is French melon d'eau.  Melon is a noun & adjective; the noun plural is melons.

Being prolific and undemanding to grow, melons were among the earliest plants domesticated and in Greek, “melon” was used in a generic way for many foreign fruits, a fate which would also befall apple, thus the naming of the pineapple and in some Old English texts, cucumbers are referred to as eorþæppla (literally "earth-apples", the deductive process which produced the French pomme de terre (potato (literally “earth-apple”, the French pomme from the Latin pomum (apple; fruit)).  Apple was from the Old English æppel (apple; any kind of fruit; fruit in general), from the from Proto-Germanic ap(a)laz (source also of the Old Saxon, Old Frisian & Dutch appel, the Old Norse eple, the Old High German apful & the German Apfel), from the primitive Indo-European ab(e)l- (apple), (source also of the Gaulish avallo (fruit), the Old Irish ubull, the Lithuanian obuolys, & the Old Church Slavonic jabloko (apple)) by etymologists caution original sense of these and their relationship(s) to which is now understood as “an apple” is uncertain.  In Middle English, as late as the seventeenth century (even the earliest compliers of recipe books aren’t always explicit so some reverse-engineering based on supposition has been undertaken), it was a generic term for all fruit other than berries but including nuts (such as Old English fingeræppla (dates (literally "finger-apples) and the late fourteenth century Middle English appel of paradis (banana (literally apple of paradise)).

The twenty-first century judgment of Paris: Lindsay Lohan, Britney Spears & Paris Hilton reprise Hera, Athena, and Aphrodite, New York City, 29 November 2006.  The car was a Mercedes-Benz SLR McLaren (C199).

That generality of meaning saw “apple” named as the fruit with which the serpent tempted Eve in the Garden of Eden, creating the original sin with which we’ve all since been damned, women especially since the Bible says it was all her fault.  However, the “fruit of the forbidden tree” was unspecified in the original texts of the Book of Genesis but despite the wishful thinking of a few, in biblical scholarship there’s no support for the notion the fruit was even hinted at being an appel of paradis, however appropriate a nice plump banana might seem, given the context.  Nor is the forbidden fruit explicitly mentioned in the Holy Quran but according to traditional Islamic commentaries it was not an apple but wheat.  The Prophet may not have been concerned but in Greek mythology there was the μῆλον τῆς Ἔριδος (Golden Apple of Discord) in the story of the Judgment of Paris which the goddess Ἔρις (Eris) (Strife), tossed in the midst of the feast of the gods at the wedding of Peleus and Thetis as a prize of beauty, thus sparking a vanity-fueled dispute among Hera, Athena and Aphrodite which ultimately triggered the Trojan War.  Eris was the goddess of chaos and discord who (perhaps unsurprisingly), having not received a wedding invitation, was miffed and inscribed kallisti (To the prettiest one) on her “wedding gift” handing it to Πάρις (Paris, AKA Ἀλέξανδρος (Aléxandros) (Alexander), the son of King Priam and Queen Hecuba of Troy) who was told to choose the goddess he found most beautiful.  Judging what turned out to be one of Greek mythology's more significant beauty contests, Paris chose Aphrodite, offending Hera and Athena, the most famous consequence of their feud being the Trojan War.  Tragedy did thereafter stalk the marriage of Peleus and Thetis; of their seven sons, the only one to survive beyond infancy was Achilles.

Cookmaid with Still Life of Vegetables and Fruit (circa 1620-1625), oil on canvas by Sir Nathaniel Bacon (1585–1627).

Beginning probably in Holland in the early seventeenth century and apparently first painted by Pieter Aertsen (circa 1533-circa 1573) "cookmaid and market scenes" was a genre in painting which combined representations of produce and kitchens with themes often borrowed from the New Testament.  Two other of Sir Nathaniel's works in this vein are known still to exist: Cookmaid with Still Life of Game & Cookmaid with Still Life of Birds, both featuring healthy young ladies and there is obviously some artistic license in Cookmaid with Still Life of Vegetables and Fruit given that although every piece of produce depicted was at the time grown somewhere in England, not all simultaneously would have been in season.  Sir Nathaniel's lengthy title was too much for many and the painting has often been referred to as "Maid with Melons".  This slang use of melons is listed by many dictionaries as “vulgar” or “mildly vulgar” but does travel with the vague respectability of a classical origin: In Antiquity the plural of the Greek melon (μῆλα) (mela) was used for “a girl's breasts”.

Juicy Melons, Euston Station, London. 

A cantaloupe as one would appear in most of the world (left) and a rockmelon down under (right).

Globalization has to some extent standardized in the English language spellings and meanings which once were disparate, sometimes reversing the trend towards diversity which was noted as one of the linguistic effects of the British Empire, especially in India under the Raj where the British pillaged the local languages with only slightly less enthusiasm than they showed for gold and diamonds.  However, the names of food seem often resistant to change, presumably most often where forms are well-established and supplied by local production.  Thus what is in some places eggplant is elsewhere the aubergine.  It’s also a melon matter because in Australia, what most of the world knows as the cantaloupe (from the French cantaloup, from the Italian place name Cantalupo, a former Papal summer estate near Rome, where the melons were first grown after being introduced to Europe from the Middle East), is called the rockmelon (occasionally rock-melon) and the antipodean quirkiness is not unique, the cantaloupe in some places call the “sweet melon” or “Crenshaw melon” while in South Africa where it’s not uncommon to see fruit-stalls side-by-side, one might be selling cantaloupes and the other spanspeks (from the Afrikaans Spaanse spek (literally “Spanish bacon”)).  The Australian use, once deconstructed, does make sense in that a cantaloupe does resemble some rocks but the case seems not compelling and cantaloupe is a wonderful word.  Visiting foodies will be gratified Australians follow the rest of the world when it comes to the honeydew (or honey-dew) melon, the name from the late sixteenth century honeydew (sticky sweet substance found in small drops on trees and plants), a replication of the formations in the Dutch honigdaauw and the German Honigthau.  The melon was first named in 1916 when selective breeding produced a cross between the cantaloupe and a melon native to southern African.

Baffle

Baffle (pronounced baf-uhl)

(1) To confuse, bewilder or perplex.

(2) To frustrate or confound; to thwart (a now archaic and probably obsolete seventeenth century use which didn’t of necessity involve the creation of confusion or bewilderment).

(3) To check or deflect the movement of (sound, light, fluids, etc.).

(4) To equip with a baffle or baffles.

(5) To cheat or trick; to hoodwink or deceive someone (used between the sixteenth & eighteenth centuries and now obsolete).

(6) To struggle ineffectually, as a ship in a gale (a nineteenth form rare except in Admiralty use).

(7) Publicly to disgrace, especially of a recreant knight (used between the sixteenth & seventeenth centuries and now obsolete).

(8) Something that balks, checks, or deflects (also called a baffle-board); an artificial obstruction for checking or deflecting the flow of gases (as in a boiler), sounds (as in the loudspeaker system of a radio or hi-fi set), light (as in a darkroom) or fluids (as in a tank).

(9) In audio engineering, any boxlike enclosure or flat panel for mounting a loudspeaker.

(10) In military camouflage, an architectural feature designed to confuse enemies or make them vulnerable.

(11) In coal mining, a lever for operating the throttle valve of a winding engine (US dialectal use).

1540-1550: Of uncertain origin but may have entered English from the Scots dialectal bauchle (to disgrace, treat with contempt, especially a perjured knight), from bauch or bachlen (publicly to condemn) and probably related to the early-modern French bafouer (to disgrace, to scorn, abuse or hoodwink) or the obsolete French befer (to mock) which was definitely picked up from the Scots bauchle.  The most likely root is the German natural sound of disgust, like bah which appears in the language as baff machen (to flabbergast) and the familiar modern meaning “to bewilder or confuse” is from 1640s while that of “to defeat someone's efforts” is from 1670s.  The use meaning “shielding device” dates from 1881 and “artificial obstruction” is from 1910.  The alternative spellings bafful & baffol are both obsolete.  Baffle is a noun & verb, bafflement & baffler are nouns and baffled & baffling are verbs & adjectives; the noun plural is baffles (or the rare bafflers).

As a noun, baffle emerged in the early 1880s, initially used mostly of the shielding device attached to stoves and ovens where it was short for “baffle-plate”, derived from the noun.  The earlier noun (from circa 1860) in the same sense was baffler, a word which can still be used to describe (1) something that causes one to be baffled, particularly a difficult puzzle or riddle & (1) in gaming, one of the projections inside a dice tower that serve to deflect the die unpredictably.  The noun bafflement (state of being baffled) dates from 1841 while the adjective baffling (bewildering, confusing, perplexing) was from 1733; it was the present-participle adjective from the verb baffle but also emerged in Admiralty slang (soon picked up in the merchant service) in the eighteenth century as a sailor's adjective for winds that blow variously and make headway difficult; although now rare, it survived into the age of steam.  The noun and verb bafflegab was first noted in 1952 and describes pretentious, incomprehensible, or overly technical language, especially legal or bureaucratic jargon; a synonym of gobbledygook (but not “hocus-pocus” or “mumbo-jumbo” which reference something nonsensical although use of those two is now probably proscribe because of their origin when speaking dismissively of the speech of African “witch doctors”.  The companion word is baffound (to perplex, bewilder by the use of bafflegab).

Although it had probably before been on the tips of not a few tongues, the words “baffle”, “baffling” & “baffled” in connection with Lindsay Lohan really spiked in 2016 when footage circulated of her speaking in distinctively different accent which used a conventional US English vocabulary but was delivered, with an occasionally halting delivery, the accent vaguely Russian or eastern European.  She later clarified thing by saying it was “…a mixture of most of the languages I can understand or am trying to learn”, adding that she’d been “…learning different languages since I was a child.  I'm fluent in English and French can understand Russian and am learning Turkish, Italian and Arabic”.  Taking advantage of the interest, she named the latest addition to the planet’s linguistic diversity “LiLohan” and a limited edition LiLohan clothing line was quickly made available as a philanthropic endeavour, part of the proceeds from each item sold going to Caudwell Children and the Disaster and Emergency Management Presidency of Turkey (AFAD).  Turkey is now properly called Türkiye Cumhuriyeti (Republic of Türkiye); the accepted short form Türkiye.

Baffled sump (left) and fuel tank (right).In cars, baffles are used in sumps and fuel tanks to prevent fluids sloshing around when subjected to the high lateral forces encountered in high-speed cornering.  With fuel tanks this ensures weight transfers are minimized while the purpose in a sump is to (1) avoid the oil surge or starvation which can happen if movement means the oil becomes removed from the oil-pump’s pickup & (2) assist in reducing the oil’s tendency to foam.  In Australia Ford included a baffled sump on the Falcon GTHO Phase III (1970-1971) and this was to be carried over to the abortive Phase IV (1972), the novelty with the latter being the race cars gaining tear-drop shaped “ears” welded to each side of the sump, adjacent to the oil pump.  The ears not only increased oil capacity but also, sitting as they did in the air-flow passing under the body, enhanced cooling.

Speak no evil: Alan Tudge.

Given the number of times the Australian Liberal Party has in recent years sought to celebrate the virtue of “personality responsibility” the evidence given by Alan Tudge (b 1971) to the royal commission investigating the “robodebt” scheme (a system which sought to “recover” what were alleged to be debts incurred by citizens who had failed to inform the government about their earnings) must to some have seemed baffling; not necessarily surprising, just baffling.  The scheme had been found to be unlawful but Mr Tudge, who served as (Liberal) minister for human services in 2017-2018 and was (under the Westminster system) “responsible” for the administration of “robodebt”, refused during questioning to accept ministerial responsibility for the unlawfulness of the scheme.  Despite being the minister in charge, Mr Tudge said it was not his responsibility check whether or not the robodebt scheme was lawful although he did seem to concede he was responsible for the scheme’s “lawful implementation”, adding that he assumed it was lawful, and had never been shown legal advice regarding its legality.  His position appeared to be based on what sounds a reasonable assumption: that the departmental secretary (the public servant in charge of the department) would not be implementing a program which he or she would know to be unlawful, something he described as “unfathomable”, adding that the scheme had gone through a rigorous cabinet process “which always has a legal overlay”.

Justice Jackson prosecuting, Albert Speer in the dock, Nuremberg, 1946. 

There are many books by academics, historians and former politicians which discuss the doctrine of ministerial responsibility but it's not known if the transcript of 20 June 1946 of the International Military Tribunal (the Nuremberg Trial) was in Mr Tudge's mind: Mr Justice Robert Jackson (1892–1954; US Supreme Court Justice 1941-1954; Chief US Prosecutor at the Nuremberg (IMT) trials of Nazi war criminals 1945-1946) cross-examining Albert Speer (1905–1981; Nazi court architect 1934-1942; Nazi minister of armaments and war production 1942-1945):

MR. JUSTICE JACKSON: Your statement some time ago that you had a certain responsibility as a Minister of the Government.  I should like to have you explain what responsibility you referred to when you say you assume a responsibility as a member of the Government; your common responsibility, what do you mean by your common responsibility along with others?

DEFENDANT SPEER: In my opinion, a state functionary has two types of responsibility.  One is the responsibility for his own sector and for that, of course, he is fully responsible.  But above that I think that in decisive matters there is, and must be, among the leaders a common responsibility, for who is to bear responsibility for developments, if not the close associates of the head of State?

This common responsibility, however, can only be applied to fundamental matters, it cannot be applied to details connected with other ministries or other responsible departments, for otherwise the entire discipline in the life of the state would be quite confused, and no one would ever know who is individually responsible in a particular sphere. This individual responsibility in one's own sphere must, at all events, be kept clear and distinct.

MR. JUSTICE JACKSON: Well, your point is, I take it, that you as a member of the Government and a leader in this period of time acknowledge a responsibility for its large policies, but not for all the details that occurred in their execution. Is that a fair statement of your position?

DEFENDANT SPEER: Yes, indeed.

MR. JUSTICE JACKSON: I think that concludes the cross-examination.

Alan Tudge at the 2017 Midwinter Ball with Liberal staffer Rachelle Miller.

Ms Millar also provided some interesting evidence to the “robodebt” royal commission and (pursuant to an unrelated matter) received from the Commonwealth a taxpayer-funded Aus$650,000 settlement for damages while working in two ministerial offices.  Ms Millar had accused Mr Tudge of being physically abusive towards her while in a consensual relationship and part of the settlement related to these matters, including compensation for loss of earning, hurt, distress, humiliation & medical and legal costs.  The Commonwealth did not admit liability but in paying Aus$650,000 seems to have assumed responsibility.  In a Clintonesque touch, Mr Tudge admitted he was at times sexually intimate with Ms Miller but insists he did not have “sexual intercourse” with that woman.
