Quark

Quark (pronounced kwawrk or kwahrk)

(1) In physics, any of a set of six hypothetical elementary particles (together with their antiparticles), said to be the fundamental units which combine to make up the subatomic particles known as hadrons (baryons, such as neutrons and protons, and mesons) but unable to exist in isolation.

(2) A soft creamy cheese, eaten throughout northern, central, eastern, and south-eastern Europe as well as the Low Countries, very similar to cottage cheese though not usually made with rennet

(3) In computer operating systems, an integer that uniquely identifies a text string.

(4) In informal use in the British Falkland Islands, the name given to the black-crowned night heron, Nycticorax nycticorax, the origin onomatopoeic, from the sound of the bird’s squawk.

(5) In Old & Middle English onomatopoeic slang, to croak (obsolete).

1963: A coining by US physicist Murray Gell-Mann (1929-2019), describing the discovery for which he would be awarded the 1969 Nobel Prize in Physics.  The English word quark appears un-adapted in the scientific lexicon of just about every language on Earth but the Italians invented the pleasing quarkonio, the construct being quark + -onium (termination of positronium), a meson consisting of a charm quark or a bottom quark and its own antiquark and consequently devoid of flavor (the name given to different versions of the same type of particle).  The German noun Quark (curds, (and in slang “trivial nonsense”)) has been suggested as Dr Gell-Mann’s inspiration (Gell-Mann's parents were from the Austro-Hungarian Empire).  The German form was from the late Middle High German twarc, from the Old Church Slavonic tvarogu (curds, cottage cheese), from a suffixed form of the primitive Indo-European root teue- (to swell), the source also of the Greek tyros (cheese).  Russian-American physicist George Zweig (b 1937) who (independently of Gell-Mann) co-proposed the theory of quarks, called them aces because his calculations suggested there were four of them.

Gell-Mann’s linguistic choice prevailed but the etymological speculation about quark ran as a minor footnote in the history of high-energy physics, interest stimulated after he was awarded 1969 Nobel Prize in Physics for his work on the theory of elementary particles.  From the beginning the physicist’s quark rhymed with "cork" but Gell-Mann subsequently came across quark in James Joyce’s (1882-1941) difficult (some prefer "rewarding" and Anthony Burgess (1917–1993) was a fan, claiming to find at least one gem on every page)) novel Finnegans Wake (Three quarks for Muster Mark!) and without the literary antecedent, it may thus have entered the scientific discourse as “kwork”.  Because of the context in which Joyce placed quark in the novel, Gell-Mann deduced the author intended it to rhyme with “Mark” & “Bark” and among Joyceians, there’s long been discussion about whether the source was the Old & Middle English slang meaning “croak” or the German Quark which had a technical meaning in cheese production but also was a popular colloquial term for "trivial nonsense” in the sense of “talking nonsense”.  Joyce had certainly visited parts of Germany where the term was in use but no notes have ever been uncovered which would confirm the origin.

Hawkwind, Quark, Strangeness and Charm (Charisma CDS 4008 (1977)).

It’s still scientific orthodoxy there are six quarks but there may be more.  They are known as flavors and are named (1) up, (2) down, (3) strange, (4) charmed, (5) bottom & (6) top, each manifesting in three colors, (1) red, (2) green & (3) blue.  The use of colors as a convention seems a curious choice because, not falling within the wavelength of visible light, quarks cannot possess the quality of a color in the conventional sense of the word.  However, red, green and blue are probably more mnemonic that the traditional constructions from the Ancient Greek.  Neutrons & protons are each made from three quarks, one of each color, a neutron being (2 x down + 1 x up) and a proton (2 x up + 1 x down).  Particles can be assembled using the other quarks but the resulting mass is massively larger and rapidly they decay into protons and neutrons.  Until the experiments of the early 1960s which at high-speed collided protons with electrons or other protons, it was thought neutrons & protons were fundamental particles.  It was during the observations of these collisions that it became understood quarks were the building blocks.

White cheeses.

Quark cheese (sold also as quarg) is a feature of cuisines in the Baltic and nations traditionally Germanic or Slavic-speaking as well as some Jewish sects and Turkic peoples.  It is soft and white, has a relatively short shelf-life and the appearance is similar to cottage cheese or mascarpone; in some languages the terms for that and quark are interchangeable.  The Roman historian Tacitus (Publius Cornelius Tacitus, circa 56–circa 120) in his De origine et situ Germanorum (On the Origin and Situation of the Germans (circa 98)) discussed Germanic culture (clearly they were viewed as a trouble even then) makes mention of a “fluffy white cheese” which may have been something like quark or any one of the fermented milk variations of the age.  The word quark was from the Late Middle High German quarc, twarc, & zwarg the Lower Saxon dwarg, all in use by at least the late thirteenth century and thought derived from a West Slavic equivalent, possibly the Lower Sorbian twarog, the Upper Sorbian twaroh, the Polish twaróg or the Czech & Slovak tvaroh; it was cognate with the Belarusian тварог (tvaroh) and the Russian творог (tvorog).  It’s thought the Old Slavonic tvarogъ was connected in some way with the Old Church Slavonic творъ, (tvor) (form), thus the notion of a “solidified milk which took a form”, an idea familiar in the French fromage (cheese) and the Italian formaggio (cheese).

Founded in 2004, 3 Quarks Daily is a kind of on-line selective content aggregator, augmented with some editorial material; thematically, nothing tends to dominate although the curators do insist whatever is run must be “inherently fascinating”.  That’s something obviously a matter a reader's judgment but such is cast of the net that on any given day, it’s likely many will find stuff of interest, some of which sometimes will fascinate.  Befitting a site which began when the web was barely a decade old, 3 Quarks Daily recalls the time when what the “inventor of the internet” (Al Gore; b 1948, US vice president (VPOTUS) 1993-2001 & in 2000 the next president of the United States (NPOTUS)) called the “information super-highway” could genuinely surprise and delight.  That still happens of course but more prominence is enjoyed by places with content delivered by algorithms rewarding shark-feeding populism.  The site’s name comes from the elementary nuclear particle and acknowledges the debt to James Joyce’s Finnegans Wake, the choice being an allusion to three Quarks spanning the often separate worlds of art, literature & science and the site used to award annual prizes known as Top Quark, Strange Quark & Charm Quark.  A visit to 3 Quarks Daily is highly recommended.
