Copernicium is a radioactive, artificially created, transuranic element with the atomic number 112 and the symbol Cn. Copernicium has a half-life of about thirty seconds and has no uses other than research. It is, of course, named for astronomer Nicolaus Copernicus (1473–1543), who advanced the theory of a heliocentric solar system. The naming is in line with that of other artificially created elements, which tend to be named after scientists or for places where nuclear research is conducted.

Copernicium was first created in Darmstadt, Germany in 1996 at the Gesellschaft für Schwerionenforschung (Center for Heavy Ion Research). It was officially recognized by the International Union of Pure and Applied Chemistry (IUPAC) in 2009, and at that time the Darmstadt researchers proposed the name. From their 14 July 2009 press release announcing the proposed name:

Element 112 shall be named “copernicium”

Proposed name honors astronomer Nicolaus Copernicus

In honor of scientist and astronomer Nicolaus Copernicus (1473-1543), the discovering team around Professor Sigurd Hofmann suggested the name “copernicium” with the element symbol “Cp” for the new element 112.

IUPAC approved the name in 2010, but changed the symbol to Cn, as Cp had been used in the past to designate the element now known as lutetium, which had been known as casssiopeium.

hell-bent / hell for leather / hell-bent for leather / hell-bent for election

Painting of a cowboy riding “hell for leather” down a hill on a galloping horse

“The Cowboy,” by Frederick Remington, 1902

7 June 2023

Hell bent features in a number of slang phrases. To be hell bent is to be doggedly determined, and to ride or go hell for leather or hell bent for leather (or election) is to travel fast and recklessly. The etiology of hell bent is straightforward enough, a metaphor for being on a path that will end up in the bad place, but the additions of leather and election are seemingly nonsensical. And unfortunately, as is often the case with such phrases, the recorded history of the terms doesn’t offer much insight.

We see hellishly bent pop up in the c.1566 play The Bugbears. In the scene in question two men are discussing marriage plans:

Brancatius her father is content but my master Amedeus is so hellishely bent on the muck of this world, on his pelfe & his drosse that of three thousand crownes he wyll not bate a crosse of rownd redy payment in dowry to bringe with her.

But this use of hellishly bent appears to be a simple collocation of words, rather than the use of a set phrase. There are no other recorded uses of a similar phrase for several centuries.

The Oxford English Dictionary includes the following alleged use of hell bent in Ebenezer Cooke’s 1731 poem The Maryland Muse:

Of Ab-origines in Arms,
Who far and near did then resort,
In Haste to Susquehanna Fort,
Hell bent [Full bent?] on Thoughts of Massacre,
To cut off ev’ry Marylander.

I haven’t been able to verify it, however. While a number of transcriptions of the poem use hell bent, every scan that I have found of the 1731 edition clearly reads full bent. But these scans are all of a revised, third edition. It is possible that hell was expurgated from this printing and the original did indeed use hell bent.

But hell bent is definitely in use by 1824, when it appears in a story titled The Mohawk Chief:

It was then, that casting his eyes through the window by which he sate [sic], he discovered that he was in the midst of a large encampment of savages, hideously painted, and “hell-bent” on carnage.

We get the first of the nonsensical variants by 1882, when hell bent for election appears in a delightfully comic story about a drunk billy goat. Printed in the St. Louis Post-Dispatch on 2 January 1882, it evidently appeared earlier in the San Francisco Post, but I have been unable to find that article:

“Yes, sir; and this morning, as it was rather sultry, I sent my youngest boy for a gallon of beer. He stopped on the way and put the can down to play marbles. McGinty’s old black billy-goat came along and drank up the beer—every drop of it.”

“Great Caesar!” said the court reporter, smacking his lips regretfully.

“He drank every drop of it, and nearly choked to death on the can. He stood blinking around a little for a while; then he started for a street car, with all colors set. He hit the horse square amidship, and it foundered at once.”

“Wrecked, I suppose?” said the editor.

“Precisely. The goat then glanced off, killed the driver and telescoped the car. I was sitting at the window all this time, and my attention was attracted by Gov. Perkins going down the street hell bent for election.”

“Gov. Perkins?”

“That’s the goat’s name, you see. McGinty is a strong Republican. There were four men getting a piano out of a wagon across the strreet [sic] when the Governor went through ’em like a pile driver behind time. The Steinway was sent to the manufactory and the men to the hospital. Terrible, wasn’t it?”

The fact that the goat was named for a governor—George Perkins was the Republican governor of California, 1880–83—hints that hell bent for election was already in use in reference to politicians doggedly determined to win office. And the political connection is made stronger by a one-line note appearing in the Buffalo Evening News on 10 September 1894: “Maine goes ‘hell bent for election’ today.” That day was election day in Maine that year.

And we see hell bent for election used in a context completely divorced from politics in a 15 July 1898 letter by an American sailor onboard a warship in the Spanish-American War, published in Michigan’s Jackson Daily Citizen:

As we sat around the deck waiting for the clouds (not to “roll by,” but to [“]unload”) and grumbled at our inactivity, we were suddenly greeted with the cry, “sail ho,” and away we went after her, “hell bent for election,” as Jud Smith used to say.

The variant hell for leather is attested a few years later. Why leather is unknown, although the OED includes a bracketed (i.e., not the same phrase, but perhaps related to it) citation to an 1881 glossary of dialect terms from the Isle of Wight off the south coast of England:

Hellfalleero. “They be aal quarlun and fightun hellfalleero.”

We see hell for leather in Rudyard Kipling’s 1890 The Story of the Gadsbys, a tale written as dramatic dialogue:

Capt. M.—(Jealously.) Then don’t say it! Leave him alone. It’s not bade enough to croak over. Here, Gaddy, take the chit to Bingle and ride hell-for-leather. It’ll do you good. I can’t go.

Junior Chaplain.—Do him good! (Smiling.) Give me the chit and I’ll drive. Let him lie down. Your horse is blocking my cart—please!

Capt. M.—(Slowly, without reining back.) I beg your pardon—I’ll apologize. On paper if you like.

Junior Chaplain.—(Flicking M.’s charger.) That’ll do, thanks. Turn in, Gadsby, and I’ll bring Bingle back—ahem—“hell-for-leather.”

While it’s possible that hellalleero could have morphed into hell for leather, the existence of the election variant casts doubt on this origin. Why leather? It’s anyone’s guess. Perhaps it has something to do with a horse’s tackle, the saddle, reins, etc., which are typically made of leather. That still doesn’t make much sense, but at least there’s some kind of logical connection.

And we get hell bent for leather by 1912, when it appears in the 31 October issue of the Riverside Enterprise:

When Becker took the family name and guaranteed to keep the same from shame and stain and blame in every kind of weather, he never dreamed the time was near when everyone he held most dear would look at him through eyes of fear and run hell bent for leather.

The gap in our knowledge of the phrase’s origins is unsatisfying, and hell bent for election/leather doesn’t make sense, but that’s the way with such idioms. Because such phrases come into common oral use before they appear in the published record, their origins are often murky. And language is not logical, or at least the logic driving an idiom’s coinage and spread is often lost in that murk of history.

rhubarb

Baseball players fighting on another on the field

A bench-clearing rhubarb between the Boston Red Sox and the Tampa Bay Rays, 5 June 2008

7 June 2023

Rhubarb is any one of a variety of edible stalks of the genus Rheum. It has a strong tart taste, and as a result, while rhubarb is biologically a vegetable it is often considered more like a fruit in culinary circles, where it is often used in pies and pastries. Rhubarb also used to (still?) be used as a purgative. But in slang use, rhubarb has come to mean nonsense or rubbish, and in baseball circles, a rhubarb is a dispute, argument, or fight.

The English name for the plant comes from the Anglo-Norman reubarbe (1212), which in turn is from the post-classical Latin reubarbarum, and that from the Hellenistic Greek ῥῆον βάρβαρον (rion barbaron, barbarous rheum). It was “barbarous” because it was not cultivated in ancient Greece, but rather in the Black Sea region. The English word is in place by c.1390, when it appears in the poem “The Pistel of Swete Susan”:

Columbyne and charuwé  clottes þei creve,
With ruwe and rubarbe, ragget ariht.

(Columbine and caraway flourishing in clumps,
With rue and rhubarb ragged in the right way.)

How rhubarb came to mean nonsense is uncertain, but it happened by the beginning of the nineteenth century. The sense may come from a certain theatrical practice, where actors would repeatedly utter the word rhubarb to simulate the noise of a crowd, but this practice is not attested to until considerably after the nonsense sense. Still, it may be the practice is older and just not remarked upon in print.

The earliest example of the word being used to mean nonsense that I have found is in George Colman’s 1801 play The Poor Gentleman. In Act 2, Scene 1, two soldiers, Foss, a corporal, and Ollapod, an officer, are conversing:

Foss. Why your honour, I have seen a good deal of service in the regular way; and know nothing about Associations; but I think, an’ please your honour, if men take up arms to defend their country, they deserve to be thank’d, and respected for it, and it doesn’t signify a brass farthing what they are called.

Olla. Right—the name’s nothing—merit’s all—Rhubarb’s rhubarb, call it what you will.

Earlier in the play, Ollapod remarks upon an officer ostentatiously wearing a uniform rhubarb-colored lapels. Whether his saying rhubarb’s rhubarb, call it what you will is a reference to that earlier scene or to an already existing sense of the word meaning nonsense is uncertain.

Colman’s play was quite successful, and two decades later, the line rhubarb’s rhubarb, call it what you will was quoted in the 22 September 1823 issue of The Mirror of the Stage, so it is not inconceivable that Colman was the originator of the slang sense. At the least, his play probably had a role in popularizing the sense.

We see the nonsense sense again in William Johnson Neale’s 1841 novel Paul Periwinkle:

In vain Bamboozle endeavoured to coax up a reply from the bottom of his throat, the words were frozen there. He got as far as “I—I—I,” and then the heavy fist of Alibi finished the rest of the sentence by the most forcible of all arguments, which the learned have termed the argumentum bacculinum, and the unlearned “the knock-down.”

“I hope that's finished you! You thrice-dyed incarnation of lies and rhubarb!” proceeded Alibi, speaking in his wrath as loudly as if the words could still annoy the bleeding ear of poor old Bam, who lay as flat upon the deck as if he never should rise more.

So, rhubarb meaning nonsense was well established by the mid nineteenth century, but the theatrical practice uttering the word rhubarb to simulate the murmuring of a crowd isn’t recorded until the twentieth century, although it may in fact be much older. The earliest mention of the practice that I’m aware of is in an article about the actor Elliott Dexter in the February 1919 issue of Motion Picture Magazine:

To return from the piscatorial to biographical, [Elliott] Dexter began his stage career as a supe, which is a noisy dram for extra, in “The Great Diamond Robbery,” at the American Theater, in New York. He didn’t carry a spear in this dramatic masterpiece, probably because there were no spears to carry, but he did grumble, “Rhubarb, rhubarb, rhubarb” off stage to make up the angry mob.

In baseball circles, however, a rhubarb is a dispute or a fight. It is claimed that this sense is a coinage of sportswriter Garry Schumacher, but no one has found an early use of the term by him. This baseball sense of rhubarb was popularized by famed sportscaster Walter Lanier “Red” Barber, who used the term frequently. It is likely that Barber began using rhubarb in the late 1930s when he was covering the Cincinnati Reds, but the baseball sense of the term is not recorded until 12 April 1940, when it appears in the pages of the Brooklyn Daily Eagle. By this time Barber was calling the games for the Brooklyn Dodgers, and it was he who undoubtedly brought the term to Brooklyn. The article in the Daily Eagle is about the possibility of Chicago Cubs pitcher Dizzy Dean joining the Dodgers, something that did not happen. Here rhubarb is used to mean trouble:

Well, in those not forgotten days, Leo [Durocher] was Dizzy’s friend, counsellor and guide. Probably Durocher’s sage advice kept the ex-cotton picker out of many a mess of rhubarb.

And we see the dispute sense in the pages of the New York Times on 19 May 1941, again in a reference to Brooklyn, who had played the Cubs the previous day:

There was what the boys call “a bit of a rhubarb” in the eighth when Cavarretta tried to steal home as Tamulis tossed the ball to first. In the ensuing run-down, the Cubs charged Phil’s progress was illegally blocked by Lavagetto. Umpire Al Barlick ruled otherwise.

And to round out the early appearances of the baseball sense, there is this from the New York Herald Tribune of 25 September 1942 about Larry MacPhail, manager of the Dodgers:

Unless Larry turns up some kind of rumpus today he apparently is going to stand on his last two “rhubarbs,” i.e., the recent ruckus with Bill Klem, the old arbitrator, and the telegraphic altercation recently undertaken with Bill McKechnie, the Cincinnati manager.

So, how the plant became associated with nonsense is unknown, but that slang sense probably gave rise to the theatrical practice of repeating saying rhubarb to simulate crowd noise. The idea of an angry crowd may, in turn, have given rise to the baseball sense of a dispute or fight. But the connections between all these senses are a bit tenuous.

dressed to the nines

26 August 2020

[3 June 2023: corrected the Scots translation]

To be dressed to the nines is to exhibit the very finest sartorial splendor. It is a variant of the more general to the nines, meaning to perfection, to the highest degree possible. But why the number nine?

The short answer is that no one knows. Most likely it’s an arbitrary number, like cloud nine. It has been suggested that the number nine has numerological or mystical significance and therefore appears in the phrase. But the early recorded uses of the phrase don’t hint at that. Ware (1909) claims that it is a variation on dressed to the eyen, referring to smart-looking attire, but no instances of that phrase have been found in the extant literature, and the more modern dressed to the eyes only appears after other instances of to the nines, so that can’t be the source.

We do know the phrase seems to have originated in Scotland. It first appears in a verse letter sent by a William Hamilton to Allan Ramsay on 24 July 1719:

THE bonny Lines therein thou sent me,
How to the Nines they did content me.

Robert Burns used the phrase in several of his poems later in the eighteenth century. The first is “Sketch,” from c. 1785:

Thou paints auld Nature to the nines,
In thy sweet Caledonian lines.

And in March 1787, he penned “The Answer,” which associates the phrase with clothing:

The marled plaid ye kindly spare,
By me should gratefully be ware;
            ‘Twad please me to the Nine.

In 1789 he wrote the bawdy “Come Rede Me, Dame,” which plays on the phrase by associating it with a well-endowed man:

Come rede me, dame, come tell me, dame,
   “My dame come tell me truly,
“What length o’ graith, when weel ca’d hame,
   “Will sair a woman duly?”
The carlin clew her wanton tail,
   Her wanton tail sae ready—
I learn’d a sang in Annandale,
   Nine inch will please a lady.—

But for a koontrie c—nt like mine,
   In sooth, we’re nae sae gentle;
We’ll tak tway thumb-bred to the nine,
   And that’s a sonsy p—ntle.

[graith = equipment
sair = cause distress, discomfort
carlin = old woman, crone
tway = two
thumb-bread = thumb-breadth
sonsy = impressive, good
pintle = penis, bolt, pin]

At about the same time that Burns is writing these poems, the word appears in North America, again associated with clothing and appearance. From a letter published in Philadelphia’s Independent Gazetteer on 27 March 1787:

Last Saturday, one of those notorious villains, (distinguished by the appellation of sharper) dressed in his laced cloaths, and powdered off to the nines, went on board of a brig, bound for Calais, and enquired (with an audacious confidence) for the Captain.

Dressed is added to the general phrase, making it specific to clothing, in the mid nineteenth century. From a story that appeared in New York’s Herald on 11 March 1837, and subsequently reprinted in newspapers across the United States:

One evening a smart young mechanic, “dressed to the nines.” as Ben Bowline says, might have been seen wending his way along Broadway.

cobalt

Photo of chips of a silvery metal next to a one cubic centimeter cube of the metal

Cobalt

2 June 2023

Cobalt is a hard, lustrous, silvery metal with atomic number 27 and the symbol Co. The element was first isolated by Georg Brandt in 1735, but its alloys have been known since antiquity. Long used in the production of blue pigments, today it has many uses, including in the production of lithium-ion batteries

Cobalt ores often also contain arsenic and other toxic materials, a fact that gives rise to its name, which is from the German kobalt or kobold, meaning goblin or demon because of the dangers the ore posed to miners. The German name spread to other European languages, and it appears in English as early as 1657 in a translation of a work by Paracelsus (Theophrastus von Hohenheim):

For at the first creation the four Elements lay hid in all things alike in the great mysterie: which things also were separated after the same manner and in one instant, and were divided among themselves one after another by a second separation, which is Elementary. And by this kind of Elementary separation out of the Element of the Earth things sensible and insensible, those that are eternall and those that are not eternall were parted from one another, every one obtaining its peculiar essence and free power. All that was of a woody nature was made wood. The next was mines of mettalls. A third became marcasite, talke, bisemute, pomegranate, mettallick cobalt, milsto, and many other things. A fourth precious stones of many sorts and shapes, as also stones, sands and lime. A fift was made into fruit, flowers, hearbs and seeds. A sixt into sensible living creatures, whereof some partake of eternity, as men, others doe not, as calves, sheep, &c.

Other early mentions in English include in a 1683 translation of Lazarus Ercker’s Fleta Minor:

Concerning the Cobolt oars, there are many sorts of them, some fresh and some milde, black and gray, some in trying do go easily into the Lead, but such Lead that comes by Ʋp-boyling from it, is black and red, and it afterwards doth work upon the Coppel, and dissolves, therefore it must after the first Ʋp-boyling, be cleansed again of its Wildness and must be slackd once more, so it will become white, and go clean off from the Coppel: One may also set the weightiest Cobolt Oar in a Test in the Oven, and let the smoak pass away, some of which sort do leave gray Ashes, and some a black grain upon the Test, and the rest will burn all away, but put a little Lead to it, and it will easily go in it, and also go clean off from the Coppel, and is found alike with the other Tryals.

And in John Woodward’s 1728 Fossils of All Kinds:

Cobaltum, a Marcasite frequent in Saxony. It is plentifully impregnated with Arsenic, contains Copper, and some Silver. G. Agricola […] and the rest of the Writers of Minerals take this for the Cadmia of the Antients. Being sublim’d, the Flores are of a blue colour. This the German Mineralists call Zaffir.
