Uranus is the seventh planet and the first to be recognized as such in modern times. It is at the limits of human vision and can only be seen with the naked eye by keen observers in near-perfect conditions. Over the centuries it was observed multiple times, but because its orbital period is 84 years it was not recognized as a planet until the late eighteenth century.

In 128 BCE, the astronomer Hipparchos may have observed it and entered it into his star catalog. But it was definitely observed by John Flamsteed in 1690, who catalogued it as a star and labeled 34 Tauri. Other astronomers after Flamsteed also recorded it as a star.

The first to recognize that what would come to be called Uranus was not a star was English astronomer William Herschel, who observed it on 13 and 17 March 1781 and, seeing that the object had moved between those two dates, mistook it for a comet. He announced his discovery of the “comet” to the Royal Society on 26 April 1781. The following year, astronomers Anders Johan Lexell and Johann Elert Bode independently determined that the object’s orbital trajectory meant that it was a planet, not a comet.

Realizing his mistake and that he had discovered a new planet, Herschel decided to call it Georgium Sidus (George’s Star), after King George III. The Latinate name appears in A New Review of November 1782:

The observations of all the first astronomers of Europe concurring to prove the new star discovered by Mr. Herschel to be a primary planet, he, who, as the discoverer, has the best right to give it a name, wishes it to be called the Georgium Sidus, in honour of the Prince under whose reign it was discovered, and as a debt due to that Prince by Astronomy, for taking the discoverer from a mechanical employment, end enabling him to continue to enrich science.

Herschel described his naming process in a letter to naturalist Joseph Banks, which was published in the Philosophical Transactions of the Royal Society in 1783:

This consideration then makes it necessary to give it a name, by which it may be distinguished from the rest of the planets and fixed stars. In the fabulous ages of ancient times the appellations of Mercury, Venus, Mars, Jupiter, and Saturn, were given to the planets, as being the names of their principal heroes and divinities. In the present more philosophical æra, it would hardly be allowable to have recourse to the same method, and call on Juno, Apollo, Pallas, or Minerva, for a name to our new heavenly body. The first consideration in any particular event, or remarkable incident, seems to be its chronology: if in any future age it should be asked, when this last-found planet was discovered? It would be a very satisfactory answer to say, “In the reign of King George the Third.” As a philosopher then, the name of Georgium Sidus presents itself to me, as an appellation which will conveniently convey the information of the time and country where and when it was brought to view.

But in the meantime, Bode had dubbed the planet Uranus, after the father of Saturn in classical mythology. In 1784, Bode wrote:

Bereits in der am 12ten März 1782 bei der hiesigen naturforschenden Gesellschaft vorgelesenen Abhandlung, habe ich den Namen des Vaters vom Saturn, nemlich Uranos, oder wie er mit der lateinischen Endung gewöhnlicher ist, Uranus vorgeschlagen, und habe seit dem das Vergnügen gehabt, daß verschiedene Astronomen und Mathematiker in ihren Schriften oder in Briefen an mich, diese Benennung aufgenommen oder gebilligt.

(Previously in the treatise read at the local natural history society on 12th March 1782, I have proposed the name of the father of Saturn, that is Uranos, or as it is usually with the Latin suffix, Uranus, and since then I have had the pleasure of various astronomers and mathematicians, in their writings or letters to me, recording or approving this designation.)

Uranus quickly became the standard name throughout Europe, with only Britain, for obvious reasons, opting for Georgium Sidus. The name Georgium Sidus remained in regular British use until the mid nineteenth century, when long after George III’s death, the British astronomical establishment finally bowed to the inevitable and went along with the nomenclature everyone else was using.

Regarding the pronunciation of the planet’s name, in Greek (and classical Latin, which follows the Greek) the stress is on the first syllable. The traditional English pronunciation, however, which is presumably modeled after the pronunciation of Latin adjectives ending in -anus, as in Romanus or paganus, places the emphasis on the second syllable: /jʊˈreɪnəs/. But to avoid the inevitable laughter of schoolchildren, and those adults with minds like schoolchildren, nowadays it is often pronounced with the emphasis on the first syllable and a shift in the second vowel to a schwa: /ˈjʊrənəs/. But the original pronunciation is also problematic in that the first two syllables are pronounced like the word urine. Perhaps the only solution is Futurama’s:

March Madness

March Madness is the originally popular, later trademarked, name for the US National Collegiate Athletic Association (NCAA) basketball championship tournament held each year in that month. But the phrase did not originate with the NCAA, or even with basketball for that matter.

The original sense of march madness was quite literal, referring to someone’s unusual or wild behavior in the month of March. Presumably the onset of spring was thought to alter one’s mental state. We see this literal sense in an article published in London’s European Magazine in May 1825:

It has been exceedingly well observed, that true politeness consists in ease, to which good sense is a happy auxiliary. Form and false parade stick close to the ignorant and the vulgar.

Should we not think it a very March madness to stickle for precedency, when a matter of consequence demanded that we waste not a single moment? And yet Mistress Snooks, from the city, will stand bobbing and curtseying to her neighbour, Madam Higginson, and exclaim—“La, no, madam—indeed, ma’am—’pon my honour, I can’t go first”—and all about—the rain coming down by bucket-fulls the while—who should first ascend the steps and ensconce themselves on the leathern seats of a dirty hackney-coach.

Around one hundred years later in the United States, the phrase made the leap to basketball. March marks the end of the basketball season, and in Indiana, the various high-school championship tournaments started to be referred to as March madness. The earliest example I know of is from the Rushville Republican of 11 March 1931, which connects the earlier, literal sense with the fever of a sports fan:

March Madness

The elimination of Anderson Tech, Columbus and Shelbyville were only mere flurries of what is to follow this week at the various basketball conventions in sixteen regional cities.—Newcastle Courier-Times.

Bob Stranahan evidently became afflicted with some of his own March madness, for Columbus was not eliminated, as Shelbyville can likely tell you.

Keep thinking about Lawrenceburg until supper time Saturday evening. Then if everything turns out right, BEAR DOWN ON THE SPARTANS.

Other references to various tournaments quickly appear in other Indiana papers, and over the next few decades March madness becomes a sportswriter’s term of art for any championship basketball tournament.

The earliest reference I’ve found to the NCAA championship is in the New York Daily News of 11 March 1958:

The annual March madness tips off tonight at the Garden with a tripleheader, involving four conference champions and two at-large selections, in the first round of the Eastern NCAA regionals.

The NCAA trademarked March Madness in 1989.

bohrium / nielsbohrium

Black-and-white photograph of a man in a suit

Niels Bohr, 1922

17 March 2023

Bohrium. element 107, symbol Bh, is named for physicist Niels Bohr (1885–1962). The element was first synthesized in 1981 at the Gesellschaft für Schwerionenforschung (Institute for Heavy Ion Research) in Darmstadt, Germany. But the discoverers originally proposed the name be nielsbohrium. And further complicating things, element 107 was not the first one for which Bohr was proposed as its namesake. Back in the 1970s, Russian researchers had proposed the name nielsbohrium for element 105.

Researchers at the Joint Institute of Nuclear Research at Dubna in Russia synthesized element 105 in 1968, and in 1973 they proposed the name nielsbohrium at a conference in Hamburg, Germany:

Recent works of several Dubna groups on the transactinide and superheavy elements are reviewed. New experiments on the volatility properties of kurchatovium and nielsbohrium halides were performed. Some fast techniques, based on gas thermochromatography of volatile inorganic species, were developed for the chemical identification of elements beyond 105 as well as for the superheavy elements.

But in 1970, a team at the University of California, Berkeley independently synthesized the element and proposed the name hahnium, after German chemist Otto Hahn (1879–1968). Credit for the discovery and the naming of the element, therefore, became embroiled in Cold War politics. In 1997, the International Union of Pure and Applied Chemistry (IUPAC) officially credited both teams with the discovery, but officially named the element Dubnium.

In 1981, while the name for element 105 was up in the air, researchers at the Institute of Heavy Ion Research in Darmstadt, Germany synthesized element 107, and in 1992 they proposed the name nielsbohrium. From Nature, 17 September 1992:

The heaviest known chemical elements—with half-lives of around 5 ms.—were finally named last week by scientists at the Institute of Heavy Ion Research in Darmstadt, Germany, where they were created by fusion reactions in the early 1980s. Element 107 is to be called nielsbohrium, after the atomic physicist Niels Bohr. Element 108, a fusion product of Pb208 and Fe58, is now hassium, named for the German state of Hessen, which supports the institute financially. Element 109–meitnerium—is a tribute to Lise Meitner, whose theoretical interpretation of Otto Hahn’s experiments was fundamental to the discovery of nuclear fission.

Unlike some previous attempts to name transuranic elements, this terminology is expected to be accepted by the international scientific community. During the cold war, element 104 was discovered concurrently in the Soviet Union and the United States, but debate continues on whether its name should be kurchatovium or rutherfordium, after the leading English and Soviet nuclear physicists of their time.

The naming was partially successful this time. In 1994, the IUPAC shortened the name to bohrium and gave it official status:

Elements 106 and 107 were named after Ernest Rutherford (New Zealand) and Niels Bohr (Denmark), respectively, to recognize their distinguished contributions to our knowledge of atomic structure. The Commission recommends the name Bohrium (Bh) for element 107, instead of the proposed Nielsbohrium, so that it conforms to the names of the other elements named after individuals.

blackmail

Movie poster with a drawing of a man and woman kissing while another man, in shadows, looks on

Poster for the 1929 Alfred Hitchcock film Blackmail, the first British “talkie”

15 March 2023

[16 March 2023: clarified the Norse origin]

Whence blackmail?

The mail in blackmail is unrelated to either a type of armor or the postal service. It comes from the Old Norse mál, whose root means discussion or agreement, although the English usage corresponds more closely to the Old Icelandic derivative máli meaning contract or payment. The Old English mal, meaning payment, first appears in reference to the Danegeld, cash given to Vikings to prevent them from raiding. The uncompounded word survives in Scots and northern English dialects.

Blackmail was first used to refer to protection rackets run by Scottish clan chieftains against farmers in their territory. If the farmers did not pay the mail, the chiefs would steal their crops and cattle. The black probably comes from the unsavory nature of the practice. The earliest record of the practice that I’m aware of is from the trial of one, Adam Scot, who was beheaded in 1530 for blackmailing the people of the Scottish-English border counties:

Maii 18.—ADAM SCOT of Tuschelaw, Convicted of art and part of theftuously taking Black-maill, from the time of his entry within the Castle of Edinburgh, in Ward, from John Brovne in Hoprow: And of art and part of theftuously taking Black-maill from Andrew Thorbrand and William his brother: And for art and part of theftuously taking of Black-maill from the poor Tenants of Hopcailʒow: And of art and part of theftuously taking Black-maill from the Tenants of Eschescheill.—BEHEADED.

Eventually, blackmail generalized to refer to obtaining payment through threat of force. A 1774 letter by David Hume makes jocular reference to blackmail, using it in the sense of being friendly to a scandalmonger in hopes that he will say nothing bad about him:

I think I can reckon about twenty people, not including the King, whom he has attacked in this short performance. I hope all his spleen is not exhausted. I should desire my compliments to him, were I not afraid that he would interpret the civility as paying blackmail to him.

But a clear use of blackmail to mean payment obtained through threat of force doesn’t appear until 15 December 1818, when it makes its appearance in a letter from a British officer stationed in India that is published in the Calcutta Journal and later the London Times the following year:

The Coolies were in some measure surprised […] the fellows have, however, received a lesson they will not easily forget, and whether we shall march or not is uncertain. They have long been the dread of all the country, and levied black mail in all directions.

And the sense of obtaining payment by threatening to publish scandalous information about someone, a sense that is hinted at Hume’s 1774 letter, does not make a clear appearance until the mid nineteenth century. From New York’s Evening Mirror of 22 May 1848, in reference to a rival paper:

Not a day passes that this organ of scoundrelism does not in some way insult the American people, who, we must admit, seem to take it very meekly—not to say gratefully. We wonder what chance of success a low, dirty, blackguard penny-a-liner would have who should go from this city to London to establish a paper for the purpose of abusing everything English and blackmailing theatres, artists and all persons who could be made to “bleed,” or suffer!

There is also an archaic, sense of blackmail, dating to the seventeenth century, referring to rent or other payments that are made in something other than silver coin, such as cattle or labor. This sense dates to the seventeenth century. Payment in silver coin was sometimes referred to as white rent, which is a folk etymology of quit-rent, from the Anglo-Norman quiterente, meaning a nominal payment to a lord in lieu of providing services. If one goes searching for early uses of blackmail, especially in English, as opposed to Scottish, sources, it is this sense that one is likely to find.

bit / byte

A representation of a bit (1 or 0) and the larger units of byte, kilobyte, megabyte, gigabyte, and terabyte

13 March 2023

[Added reference to nibble on 15 March 2023.]

This website comes to you in bits and bytes. But what are bits and bytes and why are they called that?

A bit is a basic unit of information that represents one of two alternative states, typically written as a 1 or a 0. The term was coined by mathematician John Wilder Tukey c.1947 while he was working at Bell Labs and Princeton University in New Jersey. The term is a play on words. It is supposedly an abbreviated form of Binary digIT, but it is also so called because it is a small piece, or literally bit, of information. It may, in fact, be a backronym, that is an acronym created from an already existing word. Tukey and his colleagues may have started talking about bits of information, and later Tukey invented the acronym from the word.

The first known use of bit in print is in a 1948 article by Tukey’s colleague at Bell Labs, Claude Shannon. The article, A Mathematical Theory of Communication, is a foundational text in the science of information theory, and its role in the history of the word bit is simply a footnote to the article’s scientific importance:

The choice of a logarithmic base corresponds to the choice of a unit for measuring information. If the base 2 is used the resulting units may be called binary digits, or more briefly bits, a word suggested by J.W. Tukey.

Byte appears around a decade later, and it too is a play on words, this time playing off of bit and bite/bite-size. A byte is a grouping of bits, typically but not necessarily eight bits, that is operated upon as a single unit. The letters of the Latin alphabet and Arabic numerals can each be represented by a single byte. (Writing systems with more than 256 characters, such as Chinese, require two or more bytes to represent each character.)

The earliest use of byte in print that I have found is in a June 1959 paper presented at a conference and published in the IRE Transactions on Electronic Computers, although the wording here indicates the term was already in use:

For operations upon fields of variable length, it is generally necessary to specify the inner structure of the field. For alphabetic fields this consists of the individual letters or other characters. For numeric fields, the structure includes the sign, if any, and the digits, if separately encoded. These sub-units collectively have been named bytes. Since the coded representation of a byte naturally varies in size, byte sizes of one to eight bits may be specified and used.

In 1962, one of the authors of that paper, Werner Buchholz, edited a book on computer systems that expanded a bit on byte’s origin:

Byte denotes a group of bits used to encode a character, or the number of bits transmitted in parallel to and from input-output units. A term other than character is used here because a given character may be represented in different applications by more than one code, and different codes may use different numbers of bits (i.e., different byte sizes). In input-output transmission the grouping of bits may be completely arbitrary and have no relation to actual characters. (The term is coined from bite, but respelled to avoid accidental mutation to bit.)

Nowadays, bytes are usually expressed in larger units designated with a prefix taken from Greek, such as kilobyte or terabyte:

  • kilo- from χίλιοι (thousand); 1,024 bytes

  • mega- from μεγα (great); 1,024 kilobytes

  • giga- from γίγας (giant); 1,024 megabytes

  • tera- from τέρας (monster); 1,024 terabytes

  • peta- from penta- πέντε- (five) and tera-; 1,024 terabytes

  • exa- from hexa- ἕξ (six); 1,024 petabytes

There is also the semi-humorous nibble or nybble referring to half a byte. That usage dates to at least 1967.
