Plutonium & Uranium

Plutonium (pronounced ploo-toh-nee-uhm)

A radioactive chemical element that is artificially derived from uranium, plutonium is a highly toxic metallic transuranic element.  It occurs in trace amounts in uranium ores and is produced in a nuclear reactor by neutron bombardment of uranium-238. The most stable and important isotope, plutonium-239, readily undergoes fission and is used as a reactor fuel in nuclear power stations and in nuclear weapons. Symbol: Pu; atomic no: 94; half-life (plutonium 239): 24,360 years; valency: 3, 4, 5, or 6; relative density (alpha modification): 19.84; melting point: 1184°F (640°C); boiling point: 5846°F (3230°C); specific gravity 19.84.  Its longest-lived isotope is Plutonium 244 with a half-life of 77 million years.

1941: The construct was Pluto (the (now dwarf-) planet), +–ium (the element ending suffix from the Latin -um (neuter singular morphological suffix) and based on Latin terms for metals such as ferrum (iron).  The –ium suffix (used most often to form adjectives) was applied as (1) a nominal suffix (2) a substantivisation of its neuter forms and (3) as an adjectival suffix.  It was associated with the formation of abstract nouns, sometimes denoting offices and groups, a linguistic practice which has long fallen from fashion.  In the New Latin, as the neuter singular morphological suffix, it was the standard suffix to append when forming names for chemical elements.  Plutonium was discovered at the University of California, Berkeley and so named because it follows the recently discovered neptunium in the periodic table and, at the time, Pluto followed Neptune in the Solar System.  The name plutonium earlier had been proposed for barium and was used sometimes in this sense early in the nineteenth century.

Pluto was from the Latin Plūtō, from the Ancient Greek Πλούτων (Ploútōn) (god of the underworld”).  In Greek mythology & Roman mythology, Pluto is remembered as the Greco-Roman god of the underworld but the ultimate origin was the Greek Ploutōn (god of wealth), from ploutos (wealth, riches (thought probably used originally in the sense of “overflowing”), from the primitive Indo-European root pleu- (to flow); the alternative Greek name Hades is also related to wealth because it is from beneath the earth that lie valuable metals & precious gems.  Although some have expressed doubt, the accepted history is it was then eleven year old Ms Venetia Burney (1918–2009) who suggested the name Pluto for the newly discovered (then) planet, aware of the procedure apparently because her uncle had earlier nominated Phobos and Deimos as names for the moons of Mars.  In 2006, the humorless International Astronomical Union (IAU) made its scandalous decision to declare, on highly technical grounds, that Pluto was not a planet but a mere dwarf and this inspired the American Dialect Society to coin the verb "to pluto" meaning "to demote or devalue something".

Uranium (pronounced yoo-rey-nee-uhm)

A white, lustrous, radioactive, metallic element, it has compounds used in photography and in coloring glass, the 235 isotope used in atomic and hydrogen bombs and as nuclear fuel in fission reactors.  A radioactive silvery-white metallic element of the actinide series, it occurs in several minerals including pitchblende, carnotite, and autunite.  Symbol: U; atomic no: 92; atomic wt: 238.0289; half-life of most stable isotope (uranium 238): 451 × 10⁹ years; valency: 2-6; relative density: 18.95 (approx.); melting point: 2075°F (1135°C); boiling point: 7473°F (4134°C); specific gravity 18.95.

1789: The construct was Uranus + (the planet) the –ium.  The element was named (using the conventions of Modern Latin) because the discovery of the planet had recently been announced.  Uranus was from the Latin Ūranus, from the Ancient Greek Οὐρανός (Ouranós), from οὐρανός (ouranós) (sky, heaven).

Nuclear Weapons

Of the first three atomic bombs built in 1945, two used plutonium as fissile material while one used uranium.  Two of the many problems faced in the project were (1) production of uranium of the required purity was slow but a bomb of this type was (relatively) simple to produce and (2) plutonium was more abundant but the engineering to create such a bomb was intricate, the results uncertain.  Two designs were thus concurrently developed: a (relatively) simple trigger-type device and a more complex implosion-type.  Trinity, code-name for the world’s first detonation of a nuclear device (New Mexico, July 1945), was one of the latter, an implosion-type plutonium bomb.  It was chosen because this was a genuine test, there being no certainty it would work whereas the trigger-type uranium device, ultimately dropped on Hiroshima a month later, was never tested because the scientists and engineers had such confidence in its design.  After the war, it was assumed the somewhat inefficient trigger mechanism wouldn’t again be used but technical problems saw production temporarily resumed, these stop-gap A-Bombs remaining in service until 1951.

It’s no longer certain the uranium-based bomb used again Hiroshima in August 1945 remains a genuine one-off.  It’s certain that in the sixty-odd years since Trinity, every nuclear weapon except the Hiroshima device was plutonium-based but, beginning in 2006, the DPRK (the Democratic People's Republic of Korea (North Korea)) conducted six nuclear tests and, despite advances in monitoring and detection techniques, it’s not clear what material was used although the consensus is all were fission (A-Bombs) and not fusion (H-Bombs) devices.  The tests, by historic standards, were low-yield, suggesting uranium, but this could be misleading because even a failed test of can produce a nuclear blast called a fizzle (when a detonation fails grossly to meet its expected yield).  The DPRK's programme will have had the odd fizzle but then so has every nation at some stage of the process but by historic standards it must be judged a success.  It was hampered by sanctions and international opposition (Beijing and Moscow as unwilling as Western powers to help the hermit kingdom join the nuclear club) but achieved the  necessary technology transfer by swapping ballistic missile blueprints with Pakistan which had detonated it's first fission device in 1998 but lacked a robust delivery system to counter the "nuclear threat" from India which had tested as early as 1974.  That transaction was illustrative of one of the two concerns the West harbours about the DPRK bomb (1) some sort of accident (and that covers everything from an unplanned detonation in some unfortunate place to a missile launch which malfunctions and hits a populated area) and (2) nuclear proliferation which happens because the technology is used by Pyongyang in the barter economy as a trade for something desirable but not available because of sanctions or other trade restrictions.

Fecund & Fertile

Fecund (pronounced fuh-khunt, fee-kuhnd or fek-uhnd)

(1) Producing or capable of producing offspring, fruit, vegetation, etc in abundance; prolific; fruitful.

(2) Figuratively, highly productive or creative intellectually; innovative.

Circa 1525: From the mid-fifteenth century Middle English fecounde from the Middle French fecund, from the Old French fecund & fecont (fruitful), from the Latin fēcundus (fruitful, fertile, productive; rich, abundant (and related to the Latin fētus (offspring) and fēmina (“woman”)), from fe-kwondo-, an adjectival suffixed form of the primitive Indo-European root dhei or dhe- (to suck, suckle), other derivatives meaning also “produce” & “yield”.  Fē in this case wasn’t a prefix but a link to fetus whereas -cundus was the adjectival suffix.  It replaced the late Middle English fecounde.  The spelling fecund was one of the “Latinizing” revisions to spelling which was part of the framework of early Modern English, (more or less) standardizing use and replacing the Middle English forms fecond, fecound & fecounde.  The Latin root itself proved fecund; from it came also felare (to suck), femina (woman (literally “she who suckles”)); felix (happy, auspicious, fruitful), fetus (offspring, pregnancy); fenum (hay (which seems literally to have meant “produce”)) and probably filia (daughter) & filius (son), assimilated from felios (originally “a suckling”).  The noun fecundity emerged in the early fifteenth century and was from the Latin fecunditatem (nominative fecunditas) (fruitfulness, fertility), from fecundus (fruitful, fertile).  The old spelling fœcund is obsolete.  Fecund is an adjective and fecundity & fecundation are nouns; the noun plural is fecundities.

In his A Dictionary of Modern English Usage (1926), Henry Fowler (1858–1933) noted without comment the shift in popular pronunciation but took the opportunity to cite the phrase of a literary critic (not a breed of which he much approved) who compared the words of HG Wells (1866-1946) & Horace Walpole (1717–1797): “The fecund Walpole and the facund Wells”.  The critic, Henry Fowler noted: “fished up the archaic facund for the sake of the play on words”.  Never much impressed by flashy displays of what he called a “pride of knowledge”, his objection here was that there was nothing in the sentence to give readers any idea of the change in meaning caused by the substituted vowel.  Both were from Latin adjectives, fēcundus (prolific) and facundus (elegant).

Fertile (pronounced fur-tl or fur-tahyl (mostly UK RP))

(1) Of land, bearing, producing, or capable of producing vegetation, crops etc, abundantly; prolific.

(2) Of living creatures, bearing or capable of bearing offspring; Capable of growth or development.

(3) Abundantly productive.

(4) Conducive to productiveness.

(5) In biology, fertilized, as an egg or ovum; fecundated; capable of developing past the egg stage.

(6) In botany, capable of producing sexual reproductive structures; capable of causing fertilization, as an anther with fully developed pollen; having spore-bearing organs, as a frond.

(7) In physics (of a nuclide) capable of being transmuted into a fissile nuclide by irradiation with neutrons (Uranium 238 and thorium 232 are fertile nuclides); (a substance not itself fissile, but able to be converted into a fissile material by irradiation in a reactor).

(8) Figuratively, of the imagination, energy etc, active, productive, prolific.

1425–1475: From the Late Middle English fertil (bearing or producing abundantly), from the Old French fertile or the Latin fertilis (bearing in abundance, fruitful, productive), from ferō (I bear, carry) and .akin to ferre (to bear), from the primitive Indo-European root bher (to carry (also “to bear children”)).  The verb fertilize dates from the 1640s in the sense of “make fertile” although the use in biology meaning “unite with an egg cell” seems not to have been used until 1859 and use didn’t become widespread for another fifteen years.  The noun fertility emerged in the mid-fifteenth century, from the earlier fertilite, from the Old French fertilité, from the Latin fertilitatem (nominative fertilitas) (fruitfulness, fertility), from fertilis (fruitful, productive).  Dating from the 1660s, the noun fertilizer was initially specific to the technical literature associated with agriculture in the sense of “something that fertilizes (land)”, and was an agent noun from the verb fertilize.  In polite society, fertilizer was adopted as euphemism for “manure” (and certainly “shit”), use documented since 1846.  The noun fertilization is attested since 1857 and was a noun of action from fertilize; it was either a creation of the English-speaking world or a borrowing of the Modern French fertilisation.  The common antonyms are barren, infertile and sterile.  Fertile is an adjective, fertility, fertilisation & fertileness are nouns, fertilize fertilized & fertilizing are verbs.  Technical terms like sub-fertile, non-fertile etc are coined as required.

The term “Fertile Crescent” was coined in 1914 was coined by US-born University of Chicago archaeologist James Breasted (1865-1935); it referred to the strip of fertile land (in the shape of an irregular crescent) described the stretching from present-day Iraq through eastern Turkey and down the Syrian and Israeli coasts.  The significance of the area in human history was it was here more than ten-thousand years ago that settlements began the practice of structured, seasonal agriculture.  The Middle English synonym childing is long obsolete but the more modern term “at risk” (of falling pregnant) survives for certain statistical purposes and was once part of the construct of a “legal fiction” in which the age at which women were presumed to be able to conceive was set as high as 65; advances in medical technology have affected this.

The difference

So often are “fecund” & “fertile” used interchangeably that there may be case to be made that in general use they are practically synonyms.  However, the use is slanted because fertile is a common word and fecund is rare; it’s the use of fertile when, strictly speaking, fecund is correct which is the frequent practice.  Technically, the two have distinct meanings although there is some overlap and agriculture is a fine case-study: Fertile specifically refers to soil rich in nutrients and able to support the growth of plants.  Fecund can refer to soil capable of supporting plant growth but it has the additional layer of describing something capable of producing an abundance of offspring or new growth.  This can refer to animals, humans, bacteria or (figuratively), ideas.  Used interchangeably, expect between specialists who need to differentiate, this linguistic swapping probably doesn’t cause many misunderstandings because the context of conversations will tend to make the meaning clear and for most of use, the distinction between a soil capable of growing plants and one doing so prolifically is tiresomely technical.  Still, as a rule of thumb, fertile can be thought of as meaning “able to support the growth of offspring or produce” while fecund implies “producing either in healthy volumes”.

Ultimate fecundity: Fast breeding

Although there are differences in meaning, fertile and fecund tend to be used interchangeably, especially in agriculture.  As adjectives, the difference is that fecund means highly fertile whereas fertile is the positive side of the fertile/infertile binary; capable of producing crops or offspring.  Fecundity may thus be thought a measure of the extent to which fertility is realised.  In nuclear physics, fertile material is that which, while not itself fissile (ie fissionable by thermal neutrons) is able to be converted into fissile material by irradiation in a reactor.  Three basic fertile materials exist: thorium-232, uranium-234 & uranium-238 and when these materials capture neutrons, respectively they are converted into uranium-233, uranium-235 & fissile plutonium-239.  Artificial isotopes formed in the reactor which can be converted into fissile material by one neutron capture include plutonium-238 and plutonium-240 which convert respectively into plutonium-239 & plutonium-241.

Obviously fertile and recently fecund.  In July 2023 Lindsay Lohan announced the birth of her first child.

Further along the scale are the actinides which demand more than one neutron capture before arriving at an isotope which is both fissile and long-lived enough to capture another neutron and reason fission instead of decaying.  These strings include (1) plutonium-242 to americium-243 to curium-244 to curium-245, (2) uranium-236 to neptunium-237 to plutonium-238 to plutonium-239 and (3) americium-241 to curium-242 to curium-243 (or, more likely, curium-242 decays to plutonium-238, which also requires one additional neutron to reach a fissile nuclide).  Since these require a total of three or four thermal neutrons eventually to fission, and a thermal neutron fission generates typically only two to three neutrons, these nuclides represent a net loss of neutrons although, in a fast reactor, they may require fewer neutrons to achieve fission, as well as producing more neutrons when they do.

Fast breeder (fusion) reactors have existed in labs for decades but, because of the need to contain sustainably very high temperatures, the challenge has always been to build something which (1) produces more energy than it consumes and (2) does so indefinitely.  On paper (and physicists admit the design is now so well understood a conceptual diagram can be sketched on a sheet in minutes) the science and engineering works so all that stands in the way is economics.  The lure of the fast breeder reactor is that, theoretically endlessly, one can produce more fissile material than it consumes (they're constructed using fertile material either wrapped around the core or encased in fuel rods).  Because plutonium-238, plutonium-240 and plutonium-242 are fertile, their accumulation is more manageable than that produced in conventional thermal reactors.  On planet Earth, the economics remain un-compelling, practical application of the technology having been thirty years off since the mid-1950s.  One proposal however transcends economics because it solves an otherwise insoluble problem.  If a facility for the manufacture of fissile material for spacecraft nuclear propulsion could be located on a space facility located at a point beyond the gravitational pull of Earth, it would be safe both to transport fertile materials to the facility and there manufacture fissile material which could provide the energy required for space exploration.

Trinitite

Trinitite (pronounced trin-a-tight)

(1) The glassy residue left on the desert floor after the Trinity nuclear bomb test of 16 July 1945 at Alamogordo, New Mexico, USA.

(2) By extension, any melt glasses left by nuclear bombs (known also as Alamogordo, atomsite glass or nuclear melt glass).

1945: Compound word trinit(y) +‎ -ite.  Trinity is from the Middle English trinitie & trinite from the Anglo-Norman trinitie or trinite (or ternite, trenite, trinetei, trinitiet & trinitet) from the Latin trīnitātem, accusative singular of trīnitās (the number three; a triad; the Trinity), from trīni (from trīnus (triple) from trēs, from the Proto-Italic trēs, from the primitive Indo-European tréyes (three)) + the suffix -itās from the Proto-Italic -itāts & -otāts from the primitive Indo-European –tehts, the suffix forming nouns indicating a state of being.  The suffix –ite is from the Ancient Greek -ίτης (-ítēs) and was adopted in Latin as part of Greek loanwords, both as –ītēs but also often as -īta.  It was used in Biblical tribal names (Thus either Levītēs or Levīta; plural in –ītae) and in the Medieval Latin of religious groups, such as Marcionītae, Ebiōnītae, Monophysītae.  It’s an adjective-forming suffix, especially of nominalised adjectives identifying groups of people as "those belonging to".  Trinitite is a noun; the noun plural is trinitites.  The verb trinitize is unrelated; it's from Christian theology and means "to divide into a trinity".

It was the physicist Robert Oppenheimer (1904–1967), head of the Manhattan Project which developed the first atomic weapons, who choose the name of the test site for the first atom bomb: Trinity.  He’s remembered for a snatch of verse he said the sight of the first atomic explosion made him recall, words from the Bhagavad Gita: Now I am become Death, the destroyer of worlds.  Oppenheimer also had a fondness for the metaphysical poetry of John Donne (1572–1631), the Church of England cleric, and said he remembered also:

As West and East
In all flat Maps—and I am one—are one
So death doth touch the Resurrection

While those lines do not a Trinity make, others do such as Batter my heart, three person’d God and the Holy Trinity permeates much of his Donne's work.

Variations since Trinity include kharitonchik (melt glasses from the Soviet nuclear bomb Semipalatinsk Test Site in Kazakhstan), impactite (metamorphic minerals caused by meteor heating of non-meteoritic materials), impact glass (melt glasses caused by meteor heating of non-meteoritic materials), fulgurite (melt glasses caused by lightning strikes) and fusion crust (metamorphic minerals on the surface of meteorites caused by atmospheric entry heating).  Trinitite has also been referred to as atomsite or Alamogordo glass (after the nearby city).

Physicist Norris Bradbury (1909–1997; director of the Los Alamos National Laboratory 1945-1970), group leader for bomb assembly, stands next to the partially assembled "Gadget" (code-name for the first plutonium A-bomb) atop the test tower, New Mexico, 16 July 1945).

The Trinity test of the plutonium A-bomb in New Mexico in July 1945 was a genuine test.  The uranium A-bomb which had also been built and which ultimately was dropped on Hiroshima in August was a device in which the scientists had such faith that it was deemed no test was necessary, something that sounds astonishing now but among all the physicists and engineers attached to the Manhattan Project (the A-bomb development team), there were no dissenting voices.  As a uranium bomb, the Hiroshima device was (at least for decades) a genuine one-off, all subsequent nuclear weapons being plutonium-based devices (and that may still be true; the details of the DPRK’s (North Korea) bombs remaining murky).  A uranium bomb turned out to be (relatively) easy to design and build and the trigger mechanism was simple but production of uranium to the specification required was a slow and exacting process given the machinery at the time available.  By contrast, a supply of weapons-grade plutonium was possible with the existing facilities but it was a formidable engineering challenge to create the trigger mechanism while ensuring the device remained within the size and weight parameters of a gravity bomb dropped from an aircraft which would have to fly thousands of miles to reach the target.  The Hiroshima bomb could be made to explode simply by firing a uranium bullet into the uranium core but if that approach was used with plutonium, all that would happen would be the melting of the core.  The solution was to surround the core with sufficient high-explosive to create the pressure required to trigger the chain reaction.  It was this process that the Trinity was staged to test.

Trinitite on the desert floor.

Although the test was over seventy-five years ago and completely fulfilled the purpose of testing the plutonium bomb, it was in another sense an extraordinary experiment in high-energy physics and even in the twenty-first century, analysis of the data and the physical aftermath at the site continues to reveal interesting discoveries.  Geological excavations in 2005 confirmed that the explosion, as predicted, initially pushed-down the ground but that it then rebounded, forcing the material upwards into the fireball in the sky where it was vaporized before cooling and crystallizing, eventually raining down in the form of the trinitite fragments.  Most of the trinitite was green because of the iron content in the sand while a smaller volume was black because their source was the iron from which Trinity’s tower structure was constructed and, being refined and processed, the iron content was much greater than that in the sand.  Finally, among all the trinitite, there was found a tiny number of red crystals which gained their color from all the copper cables which were also vaporized.  The propensity of copper to color its immediate environment was well-known, the mining conglomerate Rio Tinto formed in 1873 with a company name from the Rio Tinto (red river or Tinto River); the highly acidic river in the Sierra Morena mountains of southwestern Spain that runs red & orange because of the high copper content in the surrounding soil.

Red Trinitite.

Beginning in that fraction of a second when the nuclear age was born was the process which produced the red crystals, the extreme pressure and temperature (the Trinity site was briefly hotter than the surface of the Sun) forging a most unusual structure within one grain of the material just 10 micrometers across (barely longer than a red blood cell).  Made from silicon, copper, calcium and iron, the rare form of matter was called a quasicrystal.  Normally, crystals are made from atoms locked in a lattice that repeats in a regular pattern but quasicrystals, while having a structure that is orderly like a normal crystal, don’t have patterns which repeat and this grants quasicrystals properties forbidden to normal crystals.  First discovered in laboratory observations during the 1980s, quasicrystals also occur naturally in meteorites, matter transformed by stars, another place of extreme heat and pressure.

The Trinity test, the world's first nuclear explosion.

Until their observation in the 1980s, physicists regarded quasicrystals as “impossible” because they would have violated the rules scientists had over centuries constructed to define crystalline materials; the quasicrystal was thus a ‘black swan” moment in physics.  Traditionally, crystals were held to possess what were known as “rotational symmetries”, places where the structure could symmetrically be split in half, along one, two, three, four and six axes.  The black swan quasicrystal broke the rules or, more precisely, proved the rules were wrong, demonstrating instead an “icosahedral symmetry” a construct which includes six independent five-fold symmetry axes; as solids with these rotational symmetries, the quasicrystal is unique.  To the US military-industrial complex, it may also prove uniquely useful because, if a sample could be obtained of a quasicrystal created during nuclear tests conducted by other nations, it could be analyzed and might yield new understandings of their programs and weapons.  It’s always been possible to examine radioactive debris and gases to build models of how the devices were built and the materials used but those signatures decay.  Not only might a quasicrystal reveal new information but, and this is obviously most useful if the analytical process uses non-destructive tests, quasicrystals are a form of matter which goes as close (theoretically) to lasting forever as any yet known.

What’s sometimes described as “trinitite green” and used for glass crockery or decorative items is misleading because such purity was never in New Mexico after the blast.  A glassy material, most trinitite exists in a range between a pale to olive green but smaller quantities in red and black have also been observed, the coloration dependent on the specific minerals and materials in the blast site.  The green is a product of iron while the red comes from the copper electrical wiring used in the Trinity test equipment being fused together with the quartz and feldspar sand grains from the desert floor.  A quirk is that red trinitite is brightly fluorescent under short wave ultra-violet light whereas the more abundant green variety of typically shows little to no fluorescence under UV, the difference again due to the mineral composition.  Black trinitite is rarest, formed by virtue of the presence of iron alone from the tower with no copper content.

1400–1450: From the late Middle English delyvere & delyvery from the Anglo-Norman delivrée, from the Old French delivrer, from the Latin līberō, from līber (free), from the Old Latin loeber, from the Proto-Italic louðeros, from the primitive Indo-European hléwdheros, from hlewdh- (people) + the prefix de- (from the Latin dē-, from the preposition dē (of, from).  It was cognate with the Ancient Greek ἐλεύθερος (eleútheros), the Sanskrit रोधति (ródhati), the Dutch lieden, the German Leute and the Russian люди (ljudi) (people); the Old English æf- was a similar prefix.  The word was a noun use of the feminine past participle of delivrer (to deliver) with the suffix assimilated to –ery.  Delivery, deliverer, deliveree, deliverance & deliverability are nouns, deliver & delivered are verbs & adjectives, deliverable is a noun & adjective, delivering is a noun & verb; the noun plural is deliveries. 

Delivery systems

The definition of delivery systems tends to be elastic, ranging from simple, single-se devices to entire trans-national human and industrial processes.  A hypodermic syringe can be thought a delivery system for a vaccine yet that vital machine is just one, small, inexpensive part in the delivery system for a vaccination programme in response to a pandemic.  Such a global programme demands a delivery system with many human and mechanical components: research, development, testing, multi-jurisdiction legal & regulatory compliance, production, distribution, software, hardware, refrigeration, storage and administration, all before the first nurse has delivered even one injection.

The Manhattan Project's uranium-based Little Boy (left & dropped on Hiroshima) and the plutonium implosion-type Fat Man (right & dropped on Nagasaki).  So confident was the project team in the reliability of the uranium bomb it wasn't tested prior to use while the worlds first nuclear explosion was the "Trinity Test" conducted in the New Mexico desert on 16 July 1945 when a plutonium device was detonated.  For decades, as a uranium device, the Hiroshima was a genuine one-off, all the nuclear weapons built using plutonium but it's possible that more recent entrants to the club such as the DPRK (North Korea) and Pakistan may have been attracted to uranium because of the speed and simplicity of construction. 

Delivery systems can thus be very expensive and it's not uncommon for the cost vastly to exceed whatever it is they were created to deliver.  The Manhattan Project (1942-1947) which produced the first nuclear weapons officially cost some two billion dollars ($US2,000.000,000) at a time when a billion dollars was a lot of money.  Expressed as pre-pandemic (2018-2019) money, the A-bomb project probably cost the equivalent of some US$30 billion and somewhat more once adjusted for recent inflation.  Given the physics and engineering involved, the cost seems not unexceptional but remarkably, the development of the best-known component of the bomb's delivery system was more expensive still.  Between the first studies in 1938 and its eventual commissioning in 1944, Boeing’s B29 Superfortress absorbed over three billion dollars even though, unlike the bomb which was revolutionary and startlingly new, conceptually, the bomber was an evolution of the existing B17.  It was however a collection of challenges in engineering which grew in extent and complexity as the project progressed and it was soon realized the initial specifications would need significantly to be upgraded to produce a machine which reliably could carry the desired bomb-load at the necessary altitude over the vast distances missions in the Pacific would demand.

The Boeing B29 (Enola Gay) used to deliver "Little Boy" to Hiroshima.  It was one of the "Silverplate" run which integrated a number of weight-saving measures and aerodynamic improvements as well as the modified bomb-bay.

It was the B29's engines which were the cause of much of the effort.  Early modelling suggested the use of six or even eight engines was viable in terms of a flyable airframe but the approach would so compromise the range and load capacity it would render the thing useless for the intended purpose so the four-engine configuration had to be maintained.  Jet engines would have been the answer but at that stage of their development, they lacked power, reliability and their fuel consumption was too high so a new piston engine was needed and that it would need to be of larger capacity was obvious.  However, it needed also to be of a design which didn't significantly increase frontal area so the only solution was effectively to couple two engines, one sitting behind the other.  That delivered the necessary power and the weight increase could be tolerated but induced a tendency to overheat because the rearward components received so much less of the cooling air-flow.  What made the consequences of that worse was the use of so much weight-saving but highly combustible magnesium and although ameliorated during development and in service, the inherent problem was never entirely solved and it was only in the post-war years when a different engine was fitted that the issue vanished.  As a quirk of history, although now thought of as the A-bomb's delivery system, the B29 was obviously never designed with it in mind and when the time came, it was found it didn't fit in the bomb-bay.  The Royal Air Force's (RAF) Avro Lancaster could have carried it but the US military declined to consider that option and a special run (the "Silverplates") of B29s was constructed with the necessary modifications.

However, although a wartime necessity, the big piston engines were a military cul-de-sac but an innovation in the B-29 which was influential was the use of what would now be understood as a "computer-directed" (not "computer-controlled" as is sometimes stated) fire control systems which allowed two crew remotely to operate the four-turret defensive armament.  Systems like that, of which there were a few, were a reason the B-29 venture was so expensive but there have been analysts who have looked at the records of both it and the Manhattan Project and concluded the costs of the latter were probably understated because, as something for years top-secret until the bombing of Hiroshima was announced in August 1945, a significant proportion of the real expenses were charged elsewhere (notably distributed among the military's many other activities) to hide things from congressional view, everyone involved knowing that if something needs to be kept secret, the last people who should be told are politicians.  Estimates of the extent of the accounting slight-of-hand have varied but it has been suggested it may have been as high as 25%.  In industry, such thing are far from unknown.  It's long amused some that the failure of Ford's doomed Edsel (1958-1960) could be attributed to it being little more than a superficial variation of existing Ford & Mercury models (sharing engines, transmissions, platforms & assembly plants) yet when the brand was dumped Ford booked a loss of US$250 million (US$2.6 billion in 2023 dollars).  There were all sorts of corporate advantages in stating the loss as it was done and it involved things like charging the cost of developing one of the engines used wholly against the Edsel programme, even though it would serve in millions of Fords and Mercury models until 1976.

Beware of imitations: The US Boeing B-29 and the Soviet Tupolev Tu-4 clone.

One unintended beneficiary of the huge investment in the B29 was the Soviet Air Force.  Three B29s had fallen into Russian hands after emergency landing on Soviet territory and these, despite repeated requests, Moscow declined to return to their rightful owners, instead taking one apart and meticulously, part-by-part, duplicating every piece and from this, assembled their own which was released as the Tupolev Tu-4 (NATO reporting name: Bull).  In production between 1949-1952, the reverse-engineered clone remained on the active list of the Soviet military until 1964 and some were still in service with the Chinese PLA (People's Liberation Army) in 1987.  Although the Tupolev lacked some of the Boeing's advanced electronics, the Russian engineers managed to deliver an aircraft close in weight to the original despite not have access to some of the more exotic metals although it was later admitted to achieve that there were some compromises in the structural redundancies fitted.

The German V2 (one of the Vergeltungswaffen ("retaliatory weapons" or "reprisal weapons")), the worlds first ballistic missile.  As a delivery system, although inaccurate, even in 1945 it would have been effective had a nuclear warhead been available but its small payload limited its application as a strategic weapon and it was able to be produced at scale only because of the use of expendable slave labor. 

In a more conventional use of the spoils of war, the Americans were also the beneficiaries of the development of someone else's delivery system.  Nazi Germany’s big V2 (A4) rockets were (more-or-less) perfected at a cost which after the war was revealed to be higher even than the official number booked against the Manhattan project and that was not surprising given it was in its way just as ambitious.  In what was a hastily organised effort, the Allied occupation forces in 1945 rushed to grab as much of the material associated with the V2 as they could lay their hands on, train-loads of components, drawings, machine tools and test rigs sent westward from territory which, under the terms agreed at the Yalta Conference (February 1945) were to be handed to the Russian.  Just as significantly, there was a major round-up of German scientists, engineers and technicians who has worked on the V2, most of whom were anxious to be "rounded-up" by the Americans, the alternative being a career in Russian "employment".  The round-up (operation paperclip) remains controversial because matters like a Nazi past or complicity in the use of slave labor were often overlooked if an individual's contribution to the Cold War was thought to be of value and the V2 certainly saved the US from having to spend much money and perhaps a decade or more developing its own delivery system for nuclear warheads and not only were the ICBMs (intercontinental ballistic missiles) lineal V2 descendents, so was the Saturn V delivery system for the Apollo missions which enabled a dozen men to walk on the moon.

Post delivery: Lindsay Lohan's nursery in a theme of aquatic blue & white.

In humans, the female of the species is final component of the delivery system and on 17 Jul 2023 Lindsay Lohan announced she had delivered a baby boy, named Luai (an Arabic name which can be translated as “shield” or “protector”).  The child’s career in commerce has already begun, Ms Lohan partnering with Nestig to design not only her nautically-flavored nursery, but also a collection of baby products inspired by the imagery of the sea.  The nursery is a functional space in that the brand’s Wave dresser is adaptable to dual-use as a changing table and Nestig's cloud crib is modular and may later be converted into a toddler bed.

Football

Football (pronounced foot-bawl)

(1) As Association Football (soccer), a game in which two opposing teams of 11 players each defend goal-nets at opposite ends of a field, points being scored by placing the ball in an opponent’s net.

(2) As American football, a game in which two opposing teams of 11 players each defend goals at opposite ends of a field having goal posts at each end, with points being scored either by carrying the ball across the opponent's goal line or kicking it over the crossbar between the opponent's goal posts.

(3) By association (sometimes officially and sometimes as an alternative or informal name), any of various games played with spherical or ellipsoid balls, based usually on two teams competing (variously) to kick, head, carry, or otherwise propel the ball in the direction of each other's territory, the mechanisms of scoring varying according to the rules of the code (Rugby Union, Rugby League, Canadian Football, Australian Rules Football, Gaelic Football et al).

(4) The inflated ball (of various sizes and either spherical or ellipsoid in shape and historically made of leather but now often synthetic) used in football, the Rugby codes etc.

(5) Any person, thing or abstraction treated roughly, tossed about or a problem or (in the phrase “political football”) an issue repeatedly passed from one group or person to another and treated as a pretext for argument (often to gain political advantage) instead of being resolved.

(6) In slang (originally in the US military but now widely used), a briefcase containing the codes and options the US president would use to launch a nuclear attack, carried by a military aide and kept available to the president at all times (also as nuclear football, atomic football, black box or black bag) (by convention with an initial capital).

(7) As a modifier, football club, football ground, football fanatic, football pitch, football hooligan, football fan, football match etc.

(8) In commercial use, something sold at a reduced or special price.

1350-1400: From the Middle English fut ball, fotbal & footbal, the construct being foot + ball, the name derived from the games which involved kicking the ball.  Foot was from the Middle English fut, fot, fote & foot, from the Old English fōt, from the Proto-West Germanic fōt, from the Proto-Germanic fōts, from the primitive Indo-European pṓds.  Ball was from the Middle English bal, ball & balle, from the (unattested) Old English beall & bealla (round object, ball) or the Old Norse bǫllr (a ball), both from the Proto-Germanic balluz & ballô (ball), from the primitive Indo-European boln- (bubble), from the primitive Indo-European bel- (to blow, inflate, swell).  It was cognate with the Old Saxon ball, the Dutch bal, the Old High German bal & ballo (from which Modern German gained Ball (ball) & Ballen (bale)).  The related forms in Romance languages are borrowings from the Germanic.

Apparently in international use now less common than once (“NFL” now preferred), the term "gridiron" remains frequently used in the US describe American football including the NFL (National Football League).  The word refers to the marking originally painted on the field: two intersecting series of parallel lines running the length & breadth of the field which produced a cross-hatched effect recalling the gridirons used on stoves.  After the 1919-1920 season, the grid was replaced with yard lines still in use today but the name has stuck.  In the thirteenth century it was an instrument of torture on which victims chained before being burned by fire and in the same vein (though less gruesomely), in the 1500s it described a similar wrought grate on which meat and fish were broiled over hot coals.  In modern use, it's used of lattice-like structures (though not necessarily of iron) including in ship repair where grid irons are used as an open frame which supports vessels for examination, cleaning and repairs when out of the water and in the slang of live theatre, it's a raised framework from which lighting is suspended.  An interesting (though no longer permitted) use emerged in twentieth century land law in New Zealand where "to grid iron" was to purchase land with the boundaries drawn so remaining adjacent parcels were smaller than the minimum which could be registered in fee simple (freehold), thus preserving the buyers view and excluding the threat of undesirable neighbors.

In Australia & New Zealand, “footy” is the common slang used in all of the four major codes.  Slang terms for footballs include moleskin, pill, peanut, pigskin, pillow & pineapple.  The names are an allusion to the shape and that so many start with the letter “p” is thought mere coincidence.  The figurative sense of “something idly kicked around, something subject to hard use and many vicissitudes” which is the ancestor of the “political football” was in use as early as the 1530s while the US military slang referencing the portable device with which a US president emerged in the 1960s.  Football (in the sense of soccer) is called “the world game”: and like the game, forms of the word have spread to many languages including the Arabic كرة القدم‎ (calque), the Czech fotbal, the Dutch: voetbal (calque), the German Fußball (Fussball) (calque), the Hebrew כדורגל‎ (calque), the Japanese フットボール (futtobōru), the Korean 풋볼 (putbol), the Maltese futbol, the Portuguese futebol, the Romanian fotbal, the Russian футбо́л (futból), the Spanish fútbol, the Thai ฟุตบอล (fút-bɔn) and the Turkish futbol.  Football is a noun & verb, footballer & footballization are nouns, footballing is a verb & adjective and footballed is a verb; the noun plural is footballs.

The Nuclear Football

The “Football” (also as nuclear football, atomic football, black box or black bag) is a briefcase (reputedly made of a reinforced material with a black leather skin) which a military aide to the US president carries so at all times when the commander-in-chief is remote from designated command centres (such as the White House Situation Room), orders to the military can be issued including the command to authorize the launch of nuclear weapons.  The Football contains lists of the codes needed to transmit the launch order and the essential technical documentation required to determine the form a nuclear attack should assume.  Apparently, there’s also a check-list of the domestic measures immediately to be executed in the event of an attack including the imposition of martial law and the closing of US airspace to civilian aviation.  This was an outgrowth of the “SIOP (Single Integrated Operational Plan) Execution Handbook which codified in one publication all essential information needed in the circumstances, something developed during the administration of John Kennedy (JFK, 1917–1963; US president 1961-1963) but in the way of things familiar to those acquainted with bureaucratic inertia, the physical size (and thus the weight) of the contents grew and there are reports the package now weights in excess of 20 kg (45 lb).  Of course, everything could be contained on a single USB pen-drive (and the Football presumably includes a number of these) but because it’s something of a doomsday device, everything needs to be accessible in a WCS (worst case scenario) in which electronic devices are for whatever reason unable to be used.

Set of the War Room in Dr Strangelove (1964).  It’s presumably apocryphal but it’s said Ronald Reagan (1911-2004, US president 1981-1989) remarked his only disappointment upon becoming president was that the White House Situation Room was more like something in which an insurance company might conduct seminars than the film’s dramatic War Room set.

The first known use of something recognizable as a “Football” was during the second administration (1957-1961) of Dwight Eisenhower (1890-1969; US president 1953-1961) although in those days it contained purely the vital information and none of the independent communications connectivity which apparently was added as early as 1977.  Quite when first it was called the Football isn’t known but the term was in use during the Kennedy years and all agree it was based on the idea of the football “being passed” as happens in the game, the link being that it’s carried 24/7/365 by an on-duty military officer.  There’s also the story that “Football” was a refinement (possibly a euphemistic one) of the earlier (and also unattributed) nickname “dropkick”.  In the game of football the dropkick can be used to transfer the ball to another player and it was used as a codename in the film Dr Strangelove, a dark comedy of nuclear destruction.  However whether art imitated life or it was the other way around isn’t known and Football anyway prevailed.

The arrival of the Football in Hiroshima in May 2023 with Joe Biden (b 1942; US president since 2021) who was in town for the Group of Seven (G7) meeting was noted on Japanese Social Media although it wasn’t the first time the Football had been in the city which was the target of the first nuclear attack, Barack Obama (b 1961; US president 2009-2017) visiting in 2016.  By the time President Obama stepped off the Air Force One, the Football enabled him to unleash within 30 minutes the equivalent of over 22,000 Hiroshima-sized bombs which, while rather less than in 1969 when the when the size of the US nuclear arsenal peaked, was still quite an increase on the two deliverable weapons available in August 1945.  The thermo-nuclear (fusion) devices in use since the 1950s were also a thousand-fold (and beyond) more powerful than the fission bombs deployed against Hiroshima and Nagasaki although interestingly, while for decades the Hiroshima bomb was a genuine one-off (using uranium rather than plutonium), analysts believe in recent years uranium has again become fashionable with recent adopters such as Pakistan and the DPRK (North Korea) building them because of the relative simplicity of construction.
