Rubidium is a chemical element with atomic number 37 and the symbol Rb. It is a soft, ductile, whitish-gray alkali metal. Rubidium had few applications until the 1920s, but since then the element has had wide variety of uses, from giving fireworks a purple color to a component of atomic clocks. Rubidium-87 was used to produce a Bose-Einstein condensate in 1996, which earned the scientists a Nobel Prize in 2001.

Rubidium was discovered in 1860 by Gustav Kirchhoff and Robert Bunsen. It was discovered simultaneously with cesium. These two elements were the first ones discovered through spectrography. The pair took the name from the Latin rubidus (red), due to the two distinct lines in the red portion of the visual spectrum. The pair wrote in their 1861 announcement of their discovery:

Unter denselben sind besonders zwei rothe dadurch merkwürdig, dass sic tiorh jenseits der Fraunhofer'schen Linie A oder der mit dieser zusammenfallenden Linie Ka ɑ, also im alleräufsersten Hoth des Sonnenspetrums liegen. Wir schlagen daher für dieses Alkalimetall, mit Beziehung auf jene besonders merkwürdigen dunkelrothen Spectrallinien die Benennung Rubidium vor mit dem Symbol Rb, von rubidus, welches von den Alten für das dunkelste Roth gebraucht wird.

(Among them, two red ones are particularly remarkable in that they lie far beyond Fraunhofer's line A or the line Ka ɑ that coincides with it, and thus in the very outermost region of the solar spectrum. We therefore propose the name rubidium for this alkali metal, with reference to those particularly remarkable dark red spectral lines, with the symbol Rb, from rubidus, which is used by the ancients for the darkest red.)

hot dog

21 August 2024

Hot dog has two primary meanings, that of a sausage and that of a person who is superior or expert, especially boastfully so. Both started as American slang in the 1890s, with one, the sausage, eventually moving into standard English. But despite these similarities, the two senses are etymologically unrelated.

The sausage sense comes from the idea that dog meat is used in making the sausages. The idea that sausages are made from various unsavory ingredients is an ancient one, but here are two more proximate examples from nineteenth-century America. The first is an account of a Cockney tourist in New Orleans swearing out a complaint against a sausage vendor that appeared in the Weekly Picayune of 24 May 1841:

“Vy you see, ven I landed from sea I felt like eating a sausenger, or summit nice, and I goes to this ’ere man’s shop, and I says—‘I vants a pund o’ saussengers, but they must be a wery shuperior article. You can’t come cats’ meat over me, ’case I’s Hinglish myself.’ Vit that he gets offended, and says, ‘Ve haint cockneys, old feller; ve doesn’t go that rig.’ Velll, I buy’s ’em, and ven I takes ’em home they all laughs and says, ‘That ’ere’s a reg’lar suck!’ and I asked them vat they means, and they says, ‘Vy bless your hinnocent heyes! haven't you heard of the dog law?’ Vi’ that, your vuship, my suspicions became aroused—I hexamined the harticle, and I’m blow’d if I didn’t find one of the saussengers vos a dog’s tail, hair and all!”

[…]

The cockney expressed his determination to expose the whole transaction in his book of travels, and drawing out his diary he wrote as follows:—

“Mem.—New Orleans is a wery wile, wicious place: they kills men there with Bowie-knives and dogs with pisoned sassengers. They berries the former holesale in the swamp, and retails the latter, tails and all, as sassenger meat. It’s a ’orrible state of society!”

According to the paper, the complaint was dismissed as not being a criminal matter, and the tourist was told he was free to pursue a civil suit. The story is, in all likelihood, a fiction invented by the newspaper’s editors, but it does contain a truth about the public’s apprehension about what goes into those sausage casings.

The second actually uses the noun dog to refer to a sausage. From the Louisville, Kentucky Courier-Journal of 30 October 1881:

“Hot sau-sage! Hot sau-sage! Sau-sa-ges! Tak’ a sausage. All hot!

“Here’s the dog man,” said one of a group of men who were clustered, a night or two ago, round the refreshment counter of a late-closing restaurant in search of a nightcap. “Who’ll have a dog?”

“Nein, not dog. Clean, nice, made of de best ox and pig and little calf which dies. It is already 1 of de clock in de morning. I must sell mine sausage or not have breakfast. Tak’ a sausage? Only five cents!”

We see the phrase hot dog used to refer to sausage meat in Indiana’s Evansville Daily Courier of 14 September 1884. The context is that of saloonkeepers encouraging over-vigorous enforcement of temperance laws to the point that non-alcohol-related businesses would be adversely affected, thereby creating a backlash to the laws. Note that here hot dog is being used as a mass noun for the meat, not for individual sausages:

The line has been drawn upon the saloon only, however, and they, the saloon-keepers, are taking steps toward the dernier resort, (excuse my French,) which had to be taken at Evansville some time ago, as I have heard, i[n] regard to stopping all commercial pursuits that do not come within the pale of necessity. I learn that last night they had spies on the Pioneer Press and Tribune buildings, and they will aid the city government and Y.M.C.A. in enforcing the law to the limit. Even the innocent “wienerworst” man will be barred from dispensing hot dog on the street corner. This of course, is for the purpose of making the city ordinance regarding the patrol district and Sunday enforcement obnoxious.

Finally, we see hot dog used to refer to individual sausages on buns in New Jersey’s Paterson Daily Press of 31 December 1892:

A new adjunct to the sport [i.e., ice skating] is the Wiener wurst man with his kettle of steaming hot sausages and rolls. The he retails at a nickel, and his a very popular individual with the throng, for the sport soon creates an aching void that nothing but substantials will fill, and somehow or other a frankfurter and a roll seem to go right to the spot where the void is felt the most. The small boy has got on such familiar terms with this sort of lunch that he now refers to it as “hot dog.” “Hey, Mister, give me a hot dog quick,” was the startling order that a rosy-cheeked gamin hurled at the man as a Press reporter stood close by last night. The “hot dog” was quickly inserted in a gash in a roll, a dash of mustard also splashed on to the “dog” with a piece of whittled stick, and the order was fulfilled. The gamin had hardly dropped a nickel into the man’s hand before he was skimming off to join his companions. This proceeding was repeated time and again, and the “hot dog” man must be getting rich.

Various false etymologies for the origin of this sense of hot dog have been promulgated over the years. Perhaps the most persistent one concerns sausage vendor Harry Stevens, cartoonist T.A. “Tad” Dorgan, and the famed Polo Grounds of New York. According to the myth, c.1900 Stevens was selling the new type of snack at a New York Giants game. Dorgan recorded the event in a cartoon, labeling the sausages “hot dogs” because he didn’t know how to spell “frankfurter.” Other variants have Stevens naming the delicacy and Dorgan recording it. Unfortunately, the dates don’t work; the 1900 date for the incident at the Polo Grounds is after the term was coined. Also no one has found the Dorgan cartoon in question. There is a 1906 Dorgan cartoon featuring hot dogs at a sporting event, but besides being even later, it is a reference to a bicycle race at Madison Square Garden, not a baseball game at the Polo Grounds.

The second sense of hot dog has an entirely different origin unrelated to sausages or even food.

Dog has been used as a slang term for a person since the fourteenth century, usually in a pejorative sense. But in the late sixteenth century we begin to see uses of dog referring to a person in a sympathetic or affectionate manner. But it isn’t until the closing years of the nineteenth century that we see hot dog used to refer to a person. This use in the 18 October 1894 issue of the Wrinkle, the University of Michigan’s literary magazine, uses the phrase to refer to a man who on the surface would appear to be a desirable prospect in a fraternity’s rush, or membership drive:

A Suit of Clothes, great wonders wrought.
Two Greeks a “hot dog” freshman sought.
The Clothes they found, their favor bought.
A prize! The foxy rushers thought.
                                    Who’s Caught?

And again from the University of Michigan, we see the term defined in a January 1896 glossary of student slang:

hot-dog. Good, superior. “He has made some hot-dog drawings for ——.”

We see this sense of hot dog outside of a collegiate context in humorist William Kountz’s 1899 Billy Baxter’s Letters:

When I came up the subject was Du Bois’ Messe de Mariage. (Spelling not guaranteed.) I asked about it this morning Jim. A Messe de Mariage seems to some kind of wedding march, and bishop who is a real hot dog won’t issue a certificate unless the band plays the Messe.

Another humorist, this time George Ade, uses it to describe an expert professional gambler in his 1904 Breaking Into Society:

After Herbert had signed up all the checks and put a Cold Towel on his Head, he began to Roar somewhat and talk about chopping on the all-night Seances.

“You must not Beef,” said Cousin Jim. “A True Sport never lets on, even when they unbutton his Shoes.”

“Do you know, I sometimes suspect that I am not qualified to be a Hot Dog,” said Herbert. “I find that I begin to pass away about 2 A.M. Perhaps it is owing to some Oversight in my Early Training, but I notice that after I have taken a thousand Drinks I cannot put the Red Ball into the Corner Pocket. I have a Timid Nature, and somehow I cannot learn to whoop the Edge on a Pair of Nines. I’m afraid that I drank too much Rain-Water in my Youth. And, besides, I got into the Habit of going to bed.”

The verb, meaning to boastfully show off, dates to at least 1959.

So that’s how two phrases with much in common have startling different origins.

bit / two bits

Spanish pesos, divided into segments worth one, two, and four bits

19 August 2024

(For the computing term, click here.)

Two bits, in American speech, literally means twenty-five cents, but it is also used more generally to refer to a small valuation or as an adjective meaning cheap or insignificant. How it came to mean these things is wrapped up in the history of money in North America.

Bit itself comes from the Old English bita, literally meaning a morsel of food, a bite, but in pre-Conquest England it could also be used more generally to mean a fragment or portion of something.

In the sixteenth century, bit started to be used in underworld slang as a noun meaning money. We see this usage in the 1555 book A Manifest Detection of the Moste Vyle and Detestable Vse of Diceplay:

And whensoeuer ye take vp a cosin, be suer as nere as ye can to knowe a forehand what store of byt he hath in his buy, that is what mony he hath in his purse, & whether it bee in great cogs or in small, that is gold or siluer, and at what game he wil sonest stoupe that we may fede him wt his owne humor & haue coules redy for him.

And by the seventeenth century a more specific sense of bit had developed, that of a Spanish real, or one eighth of a peso. The Spanish peso (Spanish dollar) was the most common coin in circulation in colonial North America. The reals were also known as pieces of eight. We see this phrase in Edmund Scott’s 1606 An Exact Discourse of the Subtilties, Fashishions, Pollicies, Religion, and Ceremonies of the East Indians, in which Scott gives a rather racist account of the greediness of Chinese people:

I profered them a peece of eight a man, which they much scorned, I asked them if it were not enough for halfe an houres worke: they aunswered againe, that if they had not helped vs, we had had our house burnt, and so had lost all.

And we see bit being used to refer to a Spanish real in the minutes of a 1683 inquiry into a counterfeiting ring in Philadelphia:

The Govr telleth Ch: Pickering & Samll Buckley of their abuse to ye Governmt, in Quining of Spanish Bitts and Boston money, to the Great Damage and abuse to ye Subjects thereof. The Govr asked them whether or no they are Guilty of ye fact. They confess they have put of some of those new bitts, but they say that all their money was as good Silver as any Spanish money, and also deny that they had any hand in this matter. Charles Pickering saith he will Stand by it and be Tried; he declareth that he heard Jno. Rush Swere that he Spent halfe his time in making of Bitts.

The Govr asketh Sam11 Buckley whether he did not help to melt money, or to put in ye Copper allay into ye Silver more than Should be, and to have been at ye Stamping of new Bitts, and Strikeing on the Stamp.

And after the American Revolution, the Spanish coins continued to be widely used. (Spanish coinage would remain legal tender in the United States until 1857.) A June 1792 resolution of a group of Philadelphia merchants on the value of various forms of foreign currency uses the phrase two bits to refer to a quarter dollar:

It was Resolved,

That they will reject the said German Coin in all Payments that shall be rendered to them.—

The following Resolutions were also proposed and agreed to:—

That Johannesses weighing under Eight pennyweights will be rejected in all payments and not be received at more than they weigh; that all other Gold will be received by weight as heretofore, except only the pieces which have always passed at Fourteen Shillings.

That they will receive in payments the new pieces called Quarter Dollars, which pass at the value of Pistreens in Madeira, at 19 1–2d or two bits and a dog, ant the bitt pieces of the same stamp at 10 1-2d or one bitt and a dog.

(A pistreen was a Spanish silver coin. A dog is a coin of low value, particularly a copper coin issued in the West Indies.)

This would be the state of affairs until the turn of the twentieth century, when two bits began to be used as an adjective meaning cheap, of little value. Here is an example from Montana, in the 29 November 1900 edition of the Butte Weekly Miner:

Since the recent overwhelming defeat of everything that goes by the name of republicanism in the state of Montana, every two-bit republican newspaper in the state is busily engaged in hatching plans for the successful reorganization of the national democracy. How kind and thoughtful you are, gentlemen! However, you better attend your own funeral. The great national democratic party is perfectly capable of attending to their own business.

And this from the Idaho Daily Statesman of 26 January 1901:

One of the very gratifying features of political developments is that there is no organized opposition to the navy. While we have two-bit politicians seeking to arouse apprehension that the army will be used to subvert our liberties, there is no such cry respecting the naval arms of the service.

So that’s it, how bit made the journey from a morsel of food to a description of low-rent politicians.

roentgenium

16 August 2024

Roentgenium is a synthetic chemical element with atomic number 111 and the symbol Rg. All isotopes of the element are highly radioactive, with half-lives measured in seconds or minutes. Only a handful of roentgenium atoms have ever been created. It has no applications outside of pure research.

It was first produced in 1994 by a team led by Sigurd Hofmann at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany. Subsequent experiments in 2002 confirmed the existence of roentgenium, and the International Union of Pure and Applied Chemistry invited Hoffmann and his team to submit a proposed name in 2033:

The 2003 JWP report concluded that the criteria for discovery of an element had been fulfilled only in the case of element 111 and this by the collaboration of Hofmann et al. Following this assignment and in accordance with the procedures established by IUPAC for the naming of elements, the discoverers at GSI were invited to propose a name and symbol for element 111. The discoverers propose the name roentgenium and the symbol Rg.

This proposal lies within the long-established tradition of naming elements to honor famous scientists. Wilhelm Conrad Roentgen discovered X-rays in 1895. Their use has subsequently revolutionized medicine, found wide application in technology, and heralded the age of modern physics based on atomic and nuclear properties.

The physicist’s name is spelled Röntgen in German, but the element is spelled with an <e> replacing the umlaut as IUPAC does not use diacritical marks in its nomenclature.

supermoon

Side-by-side photos of two full Moons showing a marginal difference in size between them

Size comparison of a supermoon with an average full Moon

15 August 2024

(See also: blue moon)

Every three or four months we are treated to a spate of news stories about how this month’s full Moon will be a supermoon. And in the summer and fall of 2024, we’ll get four supermoons in a row.

But for the casual observer a supermoon is not a thing. The Moon will not appear significantly different from a regular full Moon. The hype is completely undeserved.

A supermoon is when a full or new Moon is at its closest approach (perigee) to the Earth. While a new Moon can be a supermoon, new Moons are difficult to see, a sliver of a crescent during daylight, so they don’t get the media attention. A full supermoon does have a slightly larger angular size than a normal one, about two arcminutes bigger than an average full Moon—the unaided human eye can discern a difference of about one arcminute, and the full Moon is around 30 arcminutes in size. So the difference to the casual observer (one thirtieth or three percent) is really not noticeable; most people need some kind of instrumentation to discern the difference in size. Also due to an optical illusion, the Moon in any phase will appear significantly larger when it is near the horizon than when it is high in the sky.

The one noticeable difference with a supermoon has to do with the tides. The tidal difference is due to the Sun, Moon, and Earth being in alignment (syzygy), with the gravitational pull of both the Sun and Moon adding to or canceling each other. High tides will be higher at a full supermoon, and low tides will be lower at a new supermoon. If you own a boat or are routinely affected by tidal flooding, then a supermoon might be a concern.

The term supermoon was coined by astrologer Richard Nolle in the September 1979 issue of the magazine Dell Horoscope. Nolle and other astrologers claim that earthquakes, volcanic eruptions, and other natural disasters tend to occur during supermoons. This, like anything else spewed out by astrologers, is simply not true.

I don’t want to dissuade anyone from going out to gaze at the full moon. By all means do so, whether or not it is “super.” The Moon is beautiful and well worth taking your time to view. But if you want to see an impressively large Moon, you don’t need to wait for a supermoon. Go out shortly after moonrise on any clear night. If the Moon is low on the horizon, it will appear impressively bigger than any supermoon.
