R
oRganic group. Generic symbol in chemical formulas. When there are multiple such groups to be represented, either primed (R' and R'') or subscripted (R1, R2, etc.) symbols are typically used. Cf. Ar. (Gesundheit!)

R
Rare earth element. Generic symbol in chemical formulas.

R
Range.

°R
degrees Réaumur. A temperature scale proportional to the (current) Celsius scale (°C), with water freezing at 0°R but boiling at 80°R. At the point where Celsius and Fahrenheit scales agree (-40°C = -40°F), the temperature on this scale is -32°R. There seems to be a conspiracy to make 32 an important number in temperature measurement (``thermometry'').

Réaumur's scale is clearly superior to the others, for three reasons:

  1. It can describe the greatest range of temperatures with just two digits.
  2. It is conceptually less challenging.
  3. It has just the right amount of funkiness -- not too much (°F), not too little (°C).
So the obvious question arises: why does everyone use the Fahrenheit scale (apart from one or two foreigners and maybe a scientist)? Probably the confusion of having two scales with names beginning in R (the other is Rankine's, mentioned at the °F entry) led to frustration and despair.

R
Reflector. For incandescent bulbs so designated, see R lamp.

R
Regina (Queen) or Rex (King). Queen Elizabeth of the United Kingdom does not sign with a last name; she writes `Elizabeth R.'

R
Republican. Member of the Grand Old Party (GOP).

R
Right. More interesting entry at RHS. The direction is much more frequently abbreviated than the judgement.

R
Romeo. Not an abbreviation here, just the FCC-recommended ``phonetic alphabet.'' I.e., a set of words chosen to represent alphabetic characters by their initials. You know, ``Alpha Bravo Charlie ... .'' The idea behind the choice is to have words that the listener will be able to guess at or reconstruct accurately even through noise (or narrow bandwidth, like a telephone).

The recommendation for J is ``Juliette.'' Perhaps you missed it when you were reading the jays.

R
Rook. A chess piece. The Rook initially in the corner nearer the Queen (Q) is in the QR file, for Queen's Rook; the one on the other side is in the KR file, for King's Rook (see K). When it is clear which file is meant, R can designate either. See file entry.

The piece name Rook is derived from Persian. It's etymologically unrelated to the word rook meaning crow or someone who acts like a crow.

The whole game came to Europe from Persia. The name Chess itself comes from Shah (more evident in German, where chess is called Schach).

R

RA
Right Ascension. Longitude (azimuthal angle), in a spherical polar coördinate earth-centered system used for astronomy. Zero is along the sun-to-earth direction at vernal equinox, and angle increases to the east. The angle is usually expressed in time units -- from 0 up to (but not including) 24 hours, rather than 0 to 360°. The other coördinate in this system is declination (Dec).

Traditionally, star catalogs are ordered by right ascension, whereas Sears catalogs are ordered by people distant from population centers. You could look them up as they rise. (I mean the stars. The sky ones.) Of course, if you're not using a tracking mechanism, the easiest way to locate most stars is relative to the constellations (q.v.) they are part of or near to.

RAB
Radio Advertising Bureau (US). About a decade ago, someone in the leadership of this organization (I forget who), was visiting Hong Kong while contemplating the sorry state of advertising revenues for US radio broadcasters. There he happened to find for sale some novelty radios, sold in a case shaped like the letters of the word RADIO. He bought a thousand of these, the story goes, and the nucleus of an ad campaign was born. Radio began to advertise for radio advertisers in advertisements on TV. [Wait, don't write. You're not the first to discover deeply concealed irony in this.] The theme of the campaign was ``Radio - it's red hot!'' or something like that, and featured the dramatic, involuntary sacrificial immolation of one of those RADIO-shaped radios. I remember the ads, with good crackling sound effects, but I don't remember where I read the rest of this story (say around 1986). I don't think they used up the radios in takes. They could have saved the footage and made a public service spot for smoke detectors.

racaille
French for `rabble, riff-raff.' The Old French etymon of this word, attested with spellings rascaille, rascaile, and rescaille, had entered English by the fourteenth century. By the fifteenth century it had been applied to an individual, and today the collective and uncountable senses are obsolete in English.

All French dictionaries I have checked give only an uncountable or collective racaille, and no countable individual use such as is now current in English. Intrigued by a November 2005 editorial in English that claimed en passant that racaille means `hoodlum,' I searched for uses of the lexeme in French news articles. It seems that the majority of uses are still uncountable (i.e., as described in dictionaries) or at least ambiguous (e.g., attributive uses of the singular form, which might be interpreted as countable or not.) However, a countable form applicable to individuals -- perhaps originally slang -- is becoming evident. In a July 2005 article in Le Télégram, a proud mother is quoted remarking that her daughter's success in school ``prouve que le cliché `gosses de HLM = racailles' n'est pas fondé.'' (Only the quotation marks have been changed to protect the innocent. This means ``proves that the stereotype `kids from the projects = hoodlums' is unfounded.'')

The earliest instance I can find is from 1994 (this mostly reflects the limitations of my database): ``Blues des racailles'' was the debut album of Tonton David, described as having ``origines banlieusardes.'' The last phrase can be translated literally as `suburban origins,' but if you're thinking whitebread and lawn-mowers, you need to have a look at the entry for jeunes des banlieues.

There were riots in the Lille area on Christmas Eve 1998, and among those charged in connection with it were three adults with prior criminal records. Their prosecutor told the court, ``Ce sont trois voyous, trois racailles.'' [`They are three thugs, three hoodlums.'] In a phrase that would resonate in 2005, Le Figaro described Roubaix as having ``un calme précaire,'' (`a fragile calm').

rack panel standards
The American standards for equipment racks (also somewhat confusingly called cabinets) and rack panels are defined by EIA standard SE-102. The racks consist, at a minimum, of two weight-bearing rails with mounting holes at prescribed distances, as described at the U entry. The holes are arranged along a rail in a pattern that repeats every 1.75 inches (the length U). The panels are 19 inches wide.

Any individual unit of rack-mountable equipment is sold in a chassis with a firmly attached front panel, all designed to take up a whole number of U's of vertical space, and the entire width inside the rack. One mounts the equipment onto a rack by screwing the front panel to the front sides of two rails. (In the equipment I'm familiar with, the front panel is typically a steel sheet one sixteenth to one eighth of an inch thick.) Various elaborations of this system are used, particularly for heavy equipment, involving vertical rails at the back (see U entry). Regardless of these additional support mechanisms, the front panels have standard dimensions which allow them to be firmly mounted on the rails. At least twelve panel specifications are designated by letter names:

Radar
Nickname of Cpl. Walter Eugene O'Reilly, a character from the beginning until 1979 on the insufferably hip TV show M*A*S*H (1972-1983). The nickname was owed to his preternatural ability to hear the sound of an approaching medevac helicopter a few seconds before anyone else. Evidently, the Korean War took place before helicopter pilots started using radio communication. Gary Burghoff played the role, and I thought he'd found another regular gig on the TV series Seinfeld series (1990-1998), but it turns out that that role (George Costanza) was played by Jason Alexander, sixteen years his junior.

But Harry Morgan, who played the unit commander (Col. Sherman T. Potter) on M*A*S*H from 1975 to the end, really was the same actor who played Jack Webb's partner on the 1967-1970 Dragnet series. He also played a crazy general named Steele in a 1974 episode of M*A*S*H.

RADAR, radar
RAdio Detection And Ranging.

A palindrome, how 'bout that!

Invented in Britain in 1940 by Robert M. Page and others, and independently in Germany. The name was coined by S. M. Tucker.

During the war, Britain sent its developers to work in the US on rapid roll-out. Through the course of the war, there was time enough for a couple of generations of measures and countermeasures to be developed, what we now call ECM. In the course of research, it was unexpectedly discovered that microwaves didn't travel as far in humid weather -- a fact that led to development of the microwave oven. The research was conducted at the MIT Radiation Laboratory (``Rad Lab''), which was disbanded before the war ended. The lab name is often described as having been purposely chosen to be deceptive, but it's hardly inaccurate.

radial lead
Refers to a cylindrical two-lead electrical package with both leads coming out of the same end. Cf. axial lead. Symmetric lead placement is common, but asymmetric placement also occurs and may indicate an unlabelled functional asymmetry (polarity in an electrolytic capacitor, for example).

In practice, almost any capacitor package that is not a box and has two leads not in an ``axial'' configuration is liable to be called ``radial.'' The usage even extends to those bright oblong capacitors whose correct technical designation I believe to be orange drop.

Radiocarbon Dating Services
I guess this is for when you get tired of the radiocarbon club scene. Beta Analytic, Inc., claims to be the largest such dating service in the world; I don't know why they don't come up when I search Yahoo under Personals. I visited their exhibition booth at the Archaeologists' meeting, staffed by a good-looking young guy -- smart as a whip, too. (Did you know that charcoal is only 50% carbon by mass, or that typically, 14C is a part in a trillion of total carbon nuclei?) Their brochure shows a lot of serious-looking men in those irresistible surgical scrubs, working with test tubes and technical gear. They look like big-pay guys-with-careers -- grade-A husband material, not the kind of losers that try to pick you up at your sleazy Radiocarbon Lounge. I haven't had a chance to read their literature yet, but skimming it I see there's a big emphasis on professionals, reliability, and trust. It's kind of pricey -- US$250 a pop, or ``dating'' as they say -- but they promise prompt results.

radix
From the Latin for ``root'' (which also, of course, gives us words like radish and radical), this word is the ``technical'' name for what we called the ``base'' of a numeral system in high school. (``Numeral'' is a text representation of a number.) Hindu-Arabic numerals are a decimal (radix ten) positional system.

Here's a toy code to convert between different radices.

``Hexadecimal'' is one of those bastard ``New Latin'' or ``international scientific vocabulary'' words (ISV), half-Latin (-decimal) and half-Greek (hexa-) like automobile, television and electrocute.

ragtop
A ``convertible.'' A car with a tough fabric or similar top that can be lowered or removed without a trip to the shop, and sometimes even raised in time to beat the storm.

Nice Memorial Day weather. I pulled up to a light, banging time to the music against the outside of my car door. A bit ahead of me in the other lane, I noticed a guy in a ragtop; I couldn't hear his sound system. I wondered: what do people in convertibles do when some jerk like me comes up, and they can't block out the sound? There was some space ahead of him -- he could have pulled further away from me. I had Little Feat's ``Dixie Chicken'' on -- I turned up the volume. The guy in the ragtop turned and smiled, and gave me a solidarity sign.

Then one night in the lobby
Of the Commodore Hotel,
I chanced to meet a bartender
Who said he knew her well.

And as he handed me a drink,
He began to hum a song,
And all the boys at the bar
Began to sing along...

RAM
Random Access Memory. [Term usually implies RWM.] This is generally the volatile memory that goes away when the machine is disconnected (see, however, NVRAM). ``Random'' as opposed to ``sequential'' refers to the fact that any randomly chosen bit of information can be accessed immediately and therefore rapidly. Most RAM is organized in rectangular arrays of word lines and bit lines. Any code in the process of execution, and as much as possible of the data which that code requires, are stored in RAM. (For a complication, see the OVL entry.) Until the late 1960's, the RAM in most computers was in the form of arrays of small ferrite ``cores.'' A bit was encoded by the direction of magnetization of a core. (That's the origin of the term ``core dump.'') The first great success of MOS technology was the rapid take-over of the core memory market by SRAM. SRAM and especially DRAM are still the overwhelmingly dominant forms of central RAM.

Good resources are The RAM Guide and The Ultimate Memory Guide. Here's a nice general tutorial on computer systems that has substantial information on memory.

Some operating systems require a great deal of RAM.

Rambam
Short version of Hebrew Rabbi Moshe b. Maimon. Probably the most common form of name used in the West is Greek `Maimonides' (-des is the patronymic ending in Ancient Greek). Rambam is standard short form in Israel.

`Rambam' is too easy to confuse with Ramban (for R. ben Nachman, or Nachmanides).

RAMDAC
Random Access Memory (RAM) Digital-to-Analog Converter (DAC). Term for the unit that converts digital screen pixel codes into analog voltages to control physical screen display.

RAM disk
Random Access Memory (RAM) used for file storage.

ramo
The Spanish words rama and ramo make an interesting case. They are two grammatical genders of a word that has no unique natural gender (`branch'). (I mean, it could be the branch of a male, female, or hermaphrodite tree, or of a river.) Both forms are used, and their ranges of meaning overlap.

Note that most animals that reproduce sexually (and which therefore have natural gender) do not have both grammatical genders in Spanish. For example, frog and toad are la rana y el sapo. For more about that, see the sapo entry.

BTW, the Latin original of this word was ramus, a second-declension male noun, so one would expect only ramo in Spanish. On the other hand, gender wobbled a bit. One example I can think of is baculum, a Latin word meaning a staff of some sort. It was second-declension neuter, of course, but for some reason, I can't imagine why, it began to be declined male (as the word baculus) in late Roman times, until that became (I think) the word's predominant gender in Medieval Latin. In English now, a baculus (plural baculi) is a staff that serves as a symbol of authority. The restored classical form baculum is modern biological terminology for the penis-bone (found in many mammal species). The plural of baculum (in English -- as usual one uses only the nominative forms) is bacula. There is a Latin noun whose singular nominative form is bacula; it means `small berry.'

Scott Bakula plays Captain Jonathan Archer in Enterprise, a 2001 TV prequel of the original Star Trek series. The character played by Bakula is James Tiberius Kirk's childhood hero. Always some Latin, or at least Romance, connection.

The West Greek alphabet, adopted by the Etruscans and inherited by the Romans, began with alpha, beta, gamma, just like the East Greek alphabet more familiar to us. (And about like all the Semitic alphabets -- aleph, bet, gimel in Hebrew, for example.) If you rotate a capital gamma counterclockwise by 45 degrees, it looks like an angular letter cee. (Back before printing, rotation was one of the most common deformations suffered by letter glyphs.) Over time, the sound of that third letter became devoiced in Latin, so instead of a hard gee sound as in the English word goat, it had a hard cee sound as in the English word coat. A way to represent the gee sound was still wanted, so a new letter based on cee was invented and inserted in the alphabet after the letter eff (which was the old Greek letter digamma). Notice the resemblance of the glyphs C and G? Most Latin words that contained the hard cee sound (i.e., the sound of kay or Greek kappa) were originally written K, but it eventually became common to write them with a C instead. With a few exceptions (like Kaeso), K came to be used in Latin primarily to transliterate the kappa in Greek loan words. I'm not sure if specific evidence exists that bacula was originally written bakula, but it is the natural presumption.

The indecision -- whether to use cee or kay to represent the hard-cee sound, recurred in other languages that adopted versions of the Latin alphabet. English and German, which replaced runes with Latin characters very roughly about the time they replaced indigenous paganism with Christianity, both went through an early period during which neither character was dominant. Eventually, cee became dominant in English (particularly in word-initial position and in consonant clusters, and wherever the consonant was not followed by e or i) , and kay became dominant in German. In both cases, the convergence on a preferred letter involved reform of some spellings that had become established. In English, for example, the adjective ending -ick was replaced by -ic, and etymologically unrelated final -ick was also often changed (when unstressed, I suppose). This might make a little clearer why we add a -k- in forming the past tense of -ic verbs (panic, panicked; picnic, picnicked, traffic, trafficked) instead of doubling the final consonant of the root in the usual way.

Incidentally, in Spanish one increasingly finds the word área used in the transferred sense of an abstract area of ideas or activities, just as in English. This is a recent development, an anglicismo. As recently as fifty years ago, área was rarely used except in reference to physical space.

If you look over the preceding entry as a whole, I think you will agree that most of the content was related to the headword. If you don't agree, too bad.

RAMONA
Random Access Monitoring Of Narcotics Abusers. Sounds a bit more intrusive than it may be. It's not drug monitoring program for individuals, like those on probation or in the NFL. It's intended to ``involve the collection of self-report data on the life histories of people heavily involved in drug use, and the development of mathematical models of drug use careers.''

M-m-m-myyyy Ramona!

Oh wait, that was Sharona. A Ramones song? Never mind.

Ramones
James Paul McCartney, known as Paul McCartney and also as Sir Paul, has used various pseudonyms, both as a stage name and for other reasons (contractual constraints, anonymity in hotel ledgers, etc.). Early in his career he sometimes performed as Paul Ramon or Paul Ramone (or both). He was also credited as ``Paul Ramone'' when he played drums and supplied backing vocals on the Steve Miller Band song ``My Dark Hour'' on the 1969 album Brave New World. Or maybe ``Paul Ramon.'' The two spellings are within a standard deviation of web data, and I'm not curious enough to hammer it down.

Anyway, a bass player and singer named Douglas Glenn Colvin learned something of this. (Precisely what Colvin had heard or knew is either already known or never will be, since he's dead.) With this as his inspiration, he adopted the stage name Dee Dee Ramone. Two guys he was starting up a band with in 1974 followed suit, and they named their group the Ramones. All subsequent band members, including Tom, who joined before their first public performance, adopted stage names with a Ramone surname. The first names and initials that were used with the surname were uniformly uninteresting and unoriginal. It's horrifying to think that the Spice Girls represented progress of any kind at all, but there you are.

At the University of Buffalo in 1994 or so, some students formed a group they called the Algonquin Round Table. My immediate reaction was that since they were unlikely to measure up to the original and famous group whose name they took, their choice of name was in the nature of lèse majesté. If Colvin et al. had called themselves ``The McCartneys,'' it would have been something like that. So I suppose they might be praised for their restraint, of all things.

Randomly Amplified Polymorphic DNA can be analyzed statistically using the RAPDistance Package. Now you no longer have to take a stranger's word for it that Lucy from Olduvai was your grandmother.

RAPID
Responsible Agricultural Product and Information Distribution. ``RAPID is the e-commerce standards organization for the Crop Protection, Seed, and Fertilizer segments of the Ag industry.'' From a thumbnail history:
RAPID is a not-for-profit 501(c)(6) organization formed by over 70 leading agricultural companies to allow the agricultural community to take advantage of the new developments in electronic communications. This organization was formed by the American Crop Protection Association with the purpose of moving the agriculture industry manufacturers, distributors, resellers, growers and others to new levels of communications, electronic commerce and regulatory compliance and stewardship capabilities.

In the early 1990's, several agricultural companies formed the Ag [sic] Alliance for Electronic Communication (AAEC). This group began the effort to develop necessary standards and guidelines to make electronic commerce work for the entire industry. In July 1995, that organization evolved into a separate legal entity called RAPID ..., an industry consortium dedicated to bringing Electronic Commerce solutions to all of agribusiness.

RAPP
Rossiyskaya Assotsiatsiya Proletarskikh Pisateley. `Russian Association of Proletarian Writers.' An organization created in 1928 by proletarian hacks, it was dedicated to defining a truly proletarian literature and to eliminating writers whose work did not fit the definition. In 1929, RAPP received official sanction for its program of establishing the First Five-Year Plan as the sole theme of Soviet literature. The first Five-Year Plan, which had been introduced in 1928, concentrated on increasing production of iron, steel, coal, oil, machine-tools, electric power, and transport resources. Despite the exciting possibilities inherent in this heroic theme, literary production did not meet expected targets. In 1932, a decree of the Central Committee of the Communist Party of the Soviet Union abolished all existing literary organizations (including RAPP) and absorbed all professional Soviet writers into a newly created Writer's Union of the U.S.S.R.

Rare Earth
A Rock group. Not a rock group. I mean, a group that played music of the type called Rock. They had a hit in 1970 with ``Get Ready.''

For more about rock material vide infra. For more on the Rock'n'Roll-chemistry nexus, see the geology and Li entries.

rare earth
A transition metal in the lanthanide series (at. nos. 58-71). These have interesting electronic and magnetic properties associated with their incompletely filled 4f shells. Not all of them are particularly rare, compared to other atoms in that period. However, their chemical properties are similar, making them difficult to separate. Given their similarity, it has often not been commercially worthwhile to separate them. A mixture of the rare earths, called mischmetal, is the ``flint'' in disposable cigarette lighters. (Another application of unseparated hard-to-separate rare earths is didymium glass, described at the Di entry.)

Back in the 1980's, a research group found surprisingly high rare earth concentrations in meteorites that fell to earth in Antarctica -- where the chance of environmental contamination is minimal. Specifically, they discovered perfect microscopic spheres very high in rare earth content on the surface of the meteorite. This was a very puzzling discovery. Eventually, they got another publication (in Scripta Physica) out of their research -- a retraction, in which they described very similar microspheres of essentially the same composition, generated by the flint from their cigarette lighters.

I'll put in the reference when I find my file of this sort of thing. I wanted to at least mention it now because it gives me an entry in which to add the following: In Houston, Texas, on the ides of March, 2001, an eighteen-wheeler overturned and spilled its 23-ton load of frozen chickens, closing part of I-10 for several hours. The driver had lost control of the rig when he dropped his cigarette and bent over to pick it up.

The rock group called ``Rare Earth'' was originally called ``The Sunliners.'' They had some limited success and released records with MGM, Hercules, Golden World, and Verve. They signed with Motown in 1969, and the name-change was inspired or imposed by Motown execs. More at RE, but not about the rock group.

Rashi
Short version of Hebrew Rabbi Shlomo Yitzhaqi. A French Talmudist who lived from 1040 to 1105, generally regarded by Orthodox Jews as the greatest commentator on the Talmud and Bible.

Rashi script
A Hebrew script developed in the thirteenth century, used primarily for religious commentaries. For the most part the letters resemble the usual square script borrowed from Aramaic. The most strikingly different glyphs are those for aleph and bet. The aleph in this script looks too similar to the het. It's called ``Rashi script'' because it was the script one used for copying the works of Rashi. Rashi seems to have had nothing directly to do with (rather later) creation of the script that took his name.

RASS
Radio Acoustic Sounding System.

RAS Syndrome
Redundant Acronym Syndrome Syndrome. PNS Syndrome, q.v.

Ratenamerika
Japanese for `Latin America.' At least it's written with katakana characters for ra-te-n-a-me-ri-ka, rather than ra-te-na-me-ri-ka.

RATFOR
RATional FORtran.

rationale
This is not a misspelling of the adjective rational. It is a different, albeit related word, a noun pronounced with an accent on the final syllable (rhymes with ``ration Al''). The word means something like `justification,' where such justification tends to have more to do with reasoning and less to do with motivations.

RATO
Rocket-Assisted Take-Off.

Rockets, jet engines, and squid all use a backward-directed jet of fluid to generate thrust. Squid suck in the fluid (dirty water, yuck) from sides and front and squirt it out the back. Jet engines suck air in the front and mix it with fuel in a turbine. The fuel-air mix burns, and the expansion (of the air and combustion gases, mostly H2O and CO2) turns the turbine. The turning of the turbine pulls in more air and propels a jet of exhaust backward. Part of the jet force comes from the fact that the exhaust gases are under higher pressure than the intake air. It would be simpler if you just burned the fuel and used its expansion directly, but then how would you get the expansion to produce a backward-directed jet without a forward-directed jet?

Rockets are simpler in that respect. Instead of sucking in air to oxidize the fuel, they use oxidant that is carried with the vehicle, condensed in tanks, the same way fuel is carried. From a practical perspective, oxidant and fuel (reducer) are similar: volatile, dangerously combustible condensed materials in tanks. Hence, the propellants are sometimes both loosely called ``fuel.''

Similarly, jet and rocket engines both propel by burning fuel to produce a backward-directed jet, and so are somewhat similar in practical terms. Hence also, the term JATO is often used where RATO confused. Here (see pg. 2) is a clear instance of ``RATO/JATO'' being used where only RATO is meant. If you want to be charitable, you can say that RATO is jet-assisted, just not jet engine-assisted.

RATP
Régie Autonome des Transports Parisiens. For more detail visit the Subway Navigator of Paris.

RATS
The name of STAR before the marketing people messed with it.

rattle
Some days after the first time I sat on my new glasses, I noticed a rattle. I thought a lens or two might be loose in the frame. I shook the glasses and they rattled. I held the glasses by one lens frame, and they still rattled. I held them by the other, and they still rattled. I held both lens frames and shook the glasses (this was harder) and they still made a rattling sound. It was the little nose-bridge pads. At least it wasn't my wristwatch.

The scientific method is like that.

A biologist conducted a series of experiments on a grasshopper. When he shouted ``jump'' or clapped, he could make it jump (``induce saltatory behavior,'' as he wrote in journals). So he removed its front (prothoracic) legs and yelled, and the grasshopper still jumped. He removed the middle two legs (mesothoracic), and the grasshopper still jumped. Finally, he removed the rear legs (metathoracic), and the grasshopper did not jump. He concluded that a grasshopper hears with its hind legs. Fascinating similar research is described at a BBL entry.

When my old boss at Naval Research Labs (NRL) told this story over beers at the end of my first week at work, I pointed out that many insects do hear with their legs. [I think it's called keeping an ear to the ground, but I didn't say so.] Years later, he told me that this had been the first sign to him that I might be alright after all.

RAVE
Reconfigurable Automatic Virtual Environment, I suppose. The configurations can range from cave-like to wall-like. It puts me in the mind of Plato's famous metaphor of the cave. See CAVE.

RAVERS
RAil VEhicles Record System. Computer system used for tracking problems on Britain's railways.

RAWS
Remote Automated Weather Station.

Rayleigh scattering
According to Leonardo da Vinci,
I say that the blueness we see in the atmosphere is not intrinsic color, but is caused by warm vapor evaporated in minute and insensible atoms on which the solar rays fall, rendering them luminous against the infinite darkness of the fiery sphere which lies beyond and includes it.... If you produce a small quantity of smoke and if you place [behind it] a piece of black velvet on which the sun does not fall, you will see that the black stuff will appear of a beautiful blue color.... Water violently ejected in a fine spray and in a dark chamber where the sunbeams are admitted produces then blue rays.... Hence it follows, as I say, that the atmosphere assumes this azure hue by reason of the particles of moisture which catch the rays of the sun.

razor's edge
Everyone's first idea of a good thing to do was always: teflon! However, it's hard to get teflon to bind to the steel. As a result, the first common coating used on razor blades was a silicone [poly (dimethyl siloxane), to be precise]. You can get teflon to stick to the steel (or adhere, if you're speaking for attribution) by sintering the polymer with the metal. Unfortunately, most iron loses its edge under this annealing-by-another-name process. The eventual solution was to use stainless steel, which keeps its edge better at the sintering temperature. The razor companies ended up advertising the fact that they were using stainless steel and not even mentioning the teflon. Even though one could get as sharp an edge with non-stainless steels, it sounded better.

razvedka
Russian term for intelligence (spying) operations. Includes operations that are a little more intrusive than mere intelligence gathering.

According to one book:

It is impossible to translate the Russian word razvedka precisely into any foreign language. It is usually rendered as `reconnaissance' or `spying' or `intelligence gathering'. A fuller explanation of the word is that it describes any means and any actions aimed at obtaining information about an enemy, analysing it and understanding it properly, like cleaning your eyeglasses.

(Emphasis added. Actually, the whole emphasized phrase was added.) Perhaps the claim about ``any'' foreign language is overstrong. I don't imagine the author checked more than a few hundred languages before giving up, do you? Anyway, assuming that the standard for precise translation is not set so high that most words are untranslatable, I think `intelligence operations' or `secret-agent stuff' may do. This quote opens the second chapter, ``Spetsnaz and the GRU,'' of a book by ``Viktor Suvorov'' (actually Vladimir Rezun; see spetsnaz entry for details).

Spetsnaz, not to put another fine point on it, is `special ops.' Rezun goes on to say: ``Spetsnaz is one of the forms of Soviet military razvedka which occupies a place somewhere between reconnaissance and intelligence.'' It doesn't look that way to me... ``Spetsnaz differs from other forms of razvedka in that it not only seeks and finds important enemy targets, but in the majority of cases attacks and destroys them.'' I guess you could think of this as a form of constructive proof in intelligence analysis: if you destroy an enemy asset, say, then you have given a proof that it no longer exists. Okay, then: a ``destructive non-existence proof,'' if you insist. But it's really just a kind of muscular logic.

I suppose Rezun might have had a point in insisting. Among the best-known KGB spetsnaz operations was the coup against Afghan president Hafizullah Amin, two days after Christmas in 1979. This doesn't really fit entirely under the category of intelligence gathering. Then again, in 1954 a coup was orchestrated in Guatemala by the US CIA, so a somewhat similar operation (in general outcome if not in method) was conducted by an ``intelligence'' organization. But by this reasoning, the secret service protection of the US President is a treasury operation. Well, maybe it is. Still, we wouldn't say training, aiding, and advising a Guatemalan rebel army is an ``intelligence operation,'' but rather a ``covert operation.'' Eh.

Incidentally, I earlier referred the date of the Afghan coup to a US, yes US, holiday. I did this specifically because there is a natural and general pattern of taking action when one's enemies are at a lower level of readiness due to their holidays, and in this case the relevant strong enemy was the US. (If it had been Canada, I'd have written ``hours after Boxing Day,'' which sounds more aggressive.) Other examples: The 1973 Arab war against Israel, launched on Yom Kippur, the holiest Jewish holiday, and George Washington's famous crossing of the Delaware to attack Hessian troops on Christmas night in 1776. In the latter case, there is a legend that aftereffects of drunken Christmas revelry in the Hessian camp contributed to the American victory, but apparently the main advantage in the attack timing was simply that of surprise, and weather that on balance worked to American advantage.

RBDS
Radio Broadcast Data System. A system to incorporate a channel of digital information into ordinary FM broadcast signal, to ``offer a wide array of new services to listeners and advertisers.'' (Don't expect a change-station-on-advertisement feature. But you can get some text and some automatic/programmable station selection) Philadelphia was the pilot city for the EIA/CEG's promotion and more promotion of this system, which is reportedly spreading in Europe like kudzu in Georgia. EIA/CEG wants to double the number of US RBDS stations to 500.

Incidentally, while we're on the subject of kudzu (Radix puerariae). A chemical called daidzin can be extracted from it that reduces the preference of hamsters to drink alcohol rather than water, but these results (like earlier similar results with Prozac) are suspect because hamsters metabolize alcohol too quickly to achieve intoxication -- they apparently drink for the calories, and will give up alcohol for chocolate drink with similar calorie content (first preference) or tomato juice with similar content (second choice). The research was reported in 1995.

Look at it this way: FM broadcast-band frequencies are located 200 kHz apart. There's no point broadcasting sound with pitches much above 20 kHz, unless you're broadcasting for dogs, so even with stereo broadcasts they're not using 160kHz of the bandwidth allocated. There's plenty of unused bandwidth for a little bit of digital data. (No, the pun was unintentional, completely unavoidable; I do not apologize.) In fact, systems have been in place for years which piggy-back signals for private subscribers multiplexed over the public signal. Sometimes, this is where Muzak comes from -- i.e., the way franchises get their music ``piped in'' without extra wiring. (Actually, the available bandwidth is greater in principle and narrower by law: two radio stations in close geographic proximity are not allocated adjacent frequencies, but in any case the FCC limits the transmission bandwidth.)

RBI
Run[s] Batted In. Pronounced R-B-I or ribby. Since about 2002, at least some announcers and commentators on ESPN have been using the initialism as both singular and plural (e.g. ``Manny Ramirez had three RBI last night...''). The slightly jocular ``ribby'' is still treated only as a singular noun (pl. ribbies).

RBS
Royal Blind Society. An Australian group that ``is the key blindness agency in NSW and the ACT. Through specialist services, [they] work in partnership with people who are blind or vision impaired and their families, to expand the choices available to them.''

It occurs to me that window blinds, which used to be called Venetian blinds in the English, are called persianas in Spanish. Hmm. I may not have been the only one dissatisfied with the old name. ``Royal Blind Society has merged and is part of RBS.RVIB.VAF Ltd incorporating the former businesses of Royal Blind Society of NSW (RBS), Royal Victorian Institute for the Blind (RVIB) and the Vision Australia Foundation (VAF).'' A company called ``Brand by Voice'' was hired ``to position and brand the newly combined agency. Brand by Voice has extensive experience in brand development and strategy for major organizations in both the public and private sectors. ... They have worked for Qantas, Vodafone, AMP, NAB, St George, PricewaterhouseCoopers, The National Breast Cancer Foundation and the Australian Government.'' I imagine that they also invented those funny words (wallaby, etc.) and the practice of making ay and aye sound alike. (Marketing issues are discussed at the Polish entry.)

``Brand by Voice is currently [2004] in its discovery phase consulting with key stakeholders, gaining insights into specific audiences, competitors and potential challenges.'' Yeah, well, don't make it sound like an interior decorator group, or an exhibitor's booth at a duck-hunters' convention. Isn't this a charity? What are ``competitors''?

RCMP
Royal Canadian Mounted Police. You know -- the Mounties. Originally the North-West Mounted Police.

RCN, R.C.N.
Royal Canadian Navy.

The fact of being a royal dominion did not automatically confer on Canada's navy the status of ``royal'' or the right to use the term in its name. The Canadian government formally requested the honor in January 1911, and was notified on August 29 of his majesty's approval and authorization to designate the Canadian Naval Forces by ``Royal Canadian Navy.'' For details see Roger Sarty: The Maritime Defence of Canada (Toronto: Canadian Institute of Strategic Studies, 1996).

The service continued under the RCN designation until it was integrated into the Canadian Armed Forces, which formally came into being on February 1, 1968. The destruction of the RCN was the handiwork of Liberal Paul Hellyer, Defense Minister from 1964 to 1967. See Marc Milner: Canada's Navy: The First Century (Toronto, Buffalo, London: University of Toronto Press, 1999).

RCP
RealClearPolitics. A more-than-daily compilation of links to political commentary and general news. The in-house editorials have a Republican or rightward tilt, but Democratic and leftist viewpoints are represented by a fair selection of links. At some point they became affiliated with Fox News, and some RCP content is linked from <foxnews.com>.

RCP keeps track of polls on major political races (i.e., those that attract repeated polling) and computes a running average of recent ones. These ``RCP averages'' is widely cited in political commentary. RCP averages give equal weight to all polls included, regardless of size. (Theoretically, one should weight such multiple estimates by the inverse of the variance. If it can be assumed, as it often is assumed, that the different polls attempt to measure the same number, then this means that each poll should be weighted by its sample size. In other words, one should estimate support for a candidate by counting the total number of supporters over all the polls.) The crude averaging done by RCP is not too terrible since the underlying polls are clearly so flawed that the sample sizes are probably not the dominant source of error. RCP averages also make no distinction among polls of likely voters, polls of registered voters, and more inclusive polls.

RCP was founded in 2000. Since at least 2007, it has had two sister sites, also essentially news-and-commentary aggregators: RealClearSports (RCS) and RealClearMarkets (RCM).

RCT
Regents' Competency Test. A set of tests taken by New York State high school students. Passing them entitles the student to a ``Regents' Diploma.'' For many years, the tests haven't been very difficult, and some of the major ones (English, Math, Social Studies, Science) are being phased out and replaced in the period 1996-2002.

Drinking at a bar (Elmo's) last year [``last year'' when I wrote this around 1996], I met a physics BA who teaches science in a Southtowns school. He told me that one of the courses he was teaching was ``Regents Science.'' I replied that it must be fun to teach an advanced science course to good students. I was sadly mistaken. Regents science is a course for students who don't care about science at all, and are taking a course strictly to meet a distasteful requirement.

Through RCUK, the Research Councils are working together to create a common framework for research, training and knowledge transfer. In doing this RCUK will work alongside OST to further support for the UK's best academic researchers and deliver the best investment for society.''

You know, the adoption of so many loan words and even abbreviations from English into foreign languages is of significance to English speakers, because it makes foreign languages easy to understand. Here, for example, is some text from unsolicited email that I received:

Sure, you miss some of the grammatical subtleties, but basically, I got all the information out of this that I really wanted to get.

Rd., RD
RoaD. Standard abbreviation. Traditionally, of course, it was written with a lower-case d, but the US postal ``service'' encouraged the use of unpunctuated all-caps addresses to reduce the error rate in automated address-reading (a kind of pattern recognition). In the mid-1990's, I read about some USPS-funded research on automated address-reading that was going to incorporate an exciting new idea: using punctuation in the addresses as a guide. I haven't kept up, but who knows -- by now maybe they're using the fact that initial letters are more likely to be capitalized!

The Resource Description Framework (RDF) is a specification currently under development within the W3C Metadata activity. RDF is designed to provide an infrastructure to support metadata across many web-based activities. RDF is the result of a number of metadata communities bringing together their needs to provide a robust and flexible architecture for supporting metadata on the Internet and WWW. Example applications include sitemaps, content ratings, stream channel definitions, search engine data collection (web crawling), digital library collections, and distributed authoring.

RDF will allow different application communities to define the metadata property set that best serves the needs of each community. RDF will provide a uniform and interoperable means to exchange the metadata between programs and across the Web. Furthermore, RDF will provide a means for publishing both a human-readable and a machine-understandable definition of the property set itself.

RDF will use XML as the transfer syntax in order to leverage other tools and code bases being built around XML.

RDP
Rectifying-Demodulating Phonopneumograph. A device invented by Manuel Casanova, M.D., to detect lower-airway obstructions and to make a differential diagnosis between asthma and emphysema. Basically, the RDP was a microphone that did a little analog signal processing to make different kinds of lung sounds distinguishable on an oscilloscope or chart-recorder trace. Later, he used the same device for diagnosing arthritis in large joints before they begin to swell visibly. This was done by detecting the sound made by arthritic joints. The sound is a crackling like that made by crumpling some kinds of plastic wrap.

For further details, see the C&EN of August 25, 1986, p. 44.

RDP
``Reliable Datagram'' Protocol.

R, D, T & E
Research, Development, Testing and Evaluation. I've only encountered the abbreviation in a military context, and there it seems to mean only this. Other, somewhat improbable expansions are alleged, with E standing for Engineering (a bit late to begin that after testing, eh?) or with T standing for Training (subtle shift in implicit subject).

RDV
Raman Doppler Velocimetry.

RE
Rare Earth. Traditionally, the rare earth elements, or metals, are the elements of the Lanthanide series (atomic numbers 57 to 71 inclusive) which differ in the number of 4f electrons and are chemically difficult to distinguish. In magnetic work, the term is sometimes taken to include Sc and Y, in earlier periods of group IIIb (above La). Geologists count only 14 rare earths, because Promethium (Pm, elt. #61) is not naturally occurring on earth (its stablest isotope has a half-life of 17.7 years).

RE
Realencyclopädie. German, `specialist encyclopedia.' The real here is apparently the reality real from Latin realis and not the royalty real from Spanish real. The Latinate spelling, with ``cyc,'' has tended to be supplanted by the Germanized ``zyk'' over time. You can think of Realenzyklopädie as a ``serious'' or ``get real'' encyclopedia.

RE
Realencyclopädie der classischen Altertumswissenschaft. `Specialist encyclopedia for classical Antiquity.' RE seems to be a more common abbreviation for this than RA, but strictly speaking (genau genommen) RA follows convention: capitalization of nouns is preserved in abbreviations and acronyms (Abkürzung und Acronyme). (Cf. GmbH.)

readability score
A simple-minded measure of simple-mindedness. Following are three common ones popularized by word-processor grammar checkers. Angle brackets denote averages.

Flesch Reading Ease

     =   206.835 
       - 1.015 x <words per sentence>
       - 84.6 x <syllables per word>
In practice, the range is truncated to [0,100]. (I.e., FRE = max(0,min(100,"FRE")), where "FRE" is the quantity given by the formula above. Six significant digits on the constant term? This is what happens when you give calculators to monkeys. Okay, okay, it's not so bad: the precision seems to be all of 0.005 units. Since 100 units are supposed to represent no more than about 20 years of education, 0.005 represents about a millischool-year. And since a school year contains roughly 1000 hours of classroom time, this test purports to state readability differences corresponding to about one class period. Sure, why not?

Scores above ninety correspond to a fourth-grade reading level. Whoa -- 61.325! A score that is above a score of nine times a ten corresponds to a fourth-grade level of reading. Uh, 81.055. Wait till next year, kid. (Fifth grade: 80-90.) There's a lot of interesting information encoded in this formula. I guess what the FRE tells you is that the easiest-to-read sentences containing x excess syllables are those in which those extra syllables are diluted among a total of sqrt(cx) words (c = 83.34975). I never would have guessed that. Linear functions of things that monkeys can compute on a four-banger are fascinating things. (That scored a 50.557. ``Fairly difficult'' is at the ``some high school'' grade level: 50-60.) Lincoln's Gettysburg Address scores 64. (I mean the address itself scores 64, not the words ``Lincoln's Gettysburg Address.'' And now we know why he didn't begin with the much-harder-to-understand ``Eighty-seven years ago....'' ``Standard'' difficulty, 7th-8th grade: 60-70. College level ``and up'' is 0-30.)

Flesch-Kincaid Grade Level

     = -15.59
       + 0.39 x <words per sentence>
       + 11.8 x <syllables per word>
It's interesting to see that the ratio of syllable-rate and sentence-length coefficients is down to only 30.26 here from 83.35 (c) above. Evidently, sentence length is much more significant in determining grade level than in determining reading ease. Moreover, if you don't start bulking up your words with extra syllables, next year you'll have to add 2.56 words to your average sentence.

Gunning's Fog Index

     = 0.4 x ( <words per sentence> + <long words per sentence> )
(Long words are words of three or more syllables. I'm at a loss for words.)

reader-response method of literary criticism

real
An intensifier, roughly synonymous with ``really,'' that is unacceptable even in informal speech, because real is really an adjective, whereas the real really is an adverb. (And no, I don't think this makes a very good mnemonic.)

reality show
I just wanted to mention ``The Truman Show.'' This is the story of a man (played by Jim Carrey) who gradually realizes that his life is a TV show. Some considered this an exciting premise when it came out in 1998, although the current reality show genre had been around since the late eighties. In fact, Carrey and the movie were both thought certain to receive academy award (AMPAS) nominations. In the event, neither best actor nor best movie nominations came. (There were three lower-profile nominations -- supporting actor, director, and writer -- none of which it won.)

In his ``At the Movies'' column in the February 12, 1999, New York Times, Bernard Weinraub reported:

Several Hollywood marketing executives and producers were almost united in explaining why the academy snubbed ``The Truman Show.'' They said that while some newspapers and magazine critics lavishly praised the movie, people in Hollywood didn't quite get what all the hoopla was about.

``It was a critics' phenomenon, and the town never liked the movie,'' one top producer said.

A studio marketing executive said that an oft-heard comment about the movie was that it had been overpraised, and that there might have been a glimmer of resentment among actors over Mr. Carrey's relatively effortless leap from comedy to drama. The actors [sic] branch of the Academy selects the acting nominees.

In addition, Mr. Carrey's chances of an Oscar nomination may have been hurt by his winning a best-actor prize at the Golden Globes, awarded by the Hollywood Foreign Press Association...

``It may have been, `O.K., he got the Golden Globe, that's enough,' '' the marketing executive said.

really
An intensifier, roughly synonymous with ``very,'' that is acceptable in informal speech--not in formal writing.

really
An adverb meaning ``in fact.''

Really! You don't say!
Go away.

real me, the
The objective unbiased image that I have of myself, instead of the biased caricature that others have of me.

Reaney and Wilson
A Dictionary of English Surnames, by P. H. Reaney and R. M. Wilson (Routledge, 1991). The first edition of the dictionary was published by Reaney in 1958 with the title A Dictionary of British Surnames, and contained 4000 surnames. Wilson completed a second revised edition (1976) that had been begun by Reaney, with 700 additional names. In his preface to the third edition, which included 4000 additional names with their variants, Wilson explained that the ``change in title reflects the concentration on surnames of specifically English rather than Celtic origin, which has been increasingly apparent in successive editions. As a rule, Scottish, Welsh, and Irish names are only included when forms for them are found in English sources, or when they coincide in form with specifically English surnames. Scottish surnames have been adequately dealt with by G.F. Black, Irish names by E. Maclysaght, and Welsh border names by T.E. Morris ....''

That third-edition preface concludes with the following: ``[T]he etymologies suggested are usually my own, and from the nature of the surnames included tend to be either obvious or highly speculative, but experience has shown that as many enquiries are received concerning the former type as of surname as for the more difficult ones.''

For surname etymologies I usually go first to Hanks and Hodges and the book by the Kohlheims listed at the Familienname entry. If I cite only Reaney and Wilson, then it probably means that these failed me.

recent photograph
More recent than a baby picture, anyway. Personals-ad terminology.

This is probably a good place to explain about personals-ad pictures. Often it will seem that the age of the person in the picture is not consistent with the age in the profile. Here are some rules that I have developed on the basis of the scientific experimental method, that will enable you to interpret the significance of this inconsistency.

  1. IF the person in the picture looks much older than the age given in the profile, then the picture gives a more accurate indication of the person's age.
  2. IF, on the other hand, the picture looks much younger than the age given in the profile, then the profile gives an age that is closer to being correct.

You probably find this bewildering, but the explanation is simple: people have a natural desire to be honest. However, it often happens that for technical reasons, the profile lists an age that differs in a quantitative way from the current chronological age of the person described. Since this is a mathematical issue, the reasons go beyond what we can explain here. However, because a so-called ``fictitious age'' is given, the person placing the ad may wish to also give an indication of so-called ``actual age.'' For this purpose, a recent photograph may be used.

On the other hand, sometimes the age listed in the ad coincides with the age of the person who places the ad. This is so unexpected that it can cause confusion, leading the reader to underestimate the age of the person advertising. In order to get around this problem, the advertiser uses a method designed to exaggerate age. The method has two steps: (1) select an OLD picture, and (2) AGE the picture. For example, suppose the advertising person is 55, but the age listed in the profile is also 55. Because this is so confusing, the reader is likely to think that the advertiser is only 40 -- a fifteen-year error! The solution is to illustrate the ad with a picture that not only is fifteen years old (taken when the advertiser was 40), but also to age this picture, not using it when it is deceptively young but instead using it now, only after it has matured fifteen years -- an old picture of an older person. This is the method of over-correction: a fifteen-year-old picture is used fifteen years after it was taken, for a total correction of thirty years.

The tangled webs people weave to be honest -- it's amazing.

Seen in a Toronto ad: ``I'm a 40-something Canadian (30 US).'' [Man, she must have aged something awful in 2007.]

Sometimes, an appropriate old photograph is not available. In these situations, the prospective dater trying to be honest is forced to use the photograph of someone else. An example can be found at the entry for I value honesty. Something similar happened with the photograph of Jennifer Kesse of Orlando, Florida, who disappeared under mysterious circumstances in late January 2006. Photographs of her appear on a missing-person website maintained by her parents. In mid-2007, one of these photos was found illustrating a personals ad for a person who described herself (or himself, who knows?) as a 25-year-old looking for ``a special older man to love, to be very good friends with.'' This ``wonderful older man'' she seeks will want to be with a young woman and ``will love me for who I am,'' as she puts it. A photograph of Kesse was also used by someone on a lesbian dating site. Detective Joel Wright of the Orlando Police Department says, ``More than likely, it's somebody just trying to make themselves look better for someone they might want to meet later on. I wonder what happens when they do meet that person.'' One guess is that the wonderful older man might be wonderfully near-blind, but then the advantage of posting a pretty picture would be limited.

I think what generally happens when someone catches a date on false pretenses is that the other person tries to be polite and cuts the date as short as possible, and that's their last date. For the person who repeatedly gets dates this way, it has to be a strange social life. Back before online dating sites, my uncle Robert advised that the ideal first date is for coffee, so you can bail out quickly. (He's a pilot.)

I'm quite proud of the fact that I managed to write this entire entry without once mentioning The Picture of Dorian Gray, but I couldn't resist the urge to crow about it.

RECHIP
REd CHilena para una Iniciativa de los Pueblos. That's a best-guess reconstruction of the Spanish from English expansion given -- `Chilean Network for a Peoples' Initiative.' (The plural possessive, FWIW, sounds a bit more fatuous in Spanish than English.) RECHIP is a group opposed to FTAA, more or less. Don't know if it existed in any form or for any purpose besides.

Rechtschreibung
German word meaning `correct spelling,' identical in construction and meaning with the Spanish and Latin word (originally transliterated from the Greek) orthographia. So all these languages have books for ``correct spelling''; English just has ``spelling books.'' It stands to reason.

Incidentally, as you will have noticed, German compound terms (particularly nouns) are typically written as single words. This makes it important to be able to recognize the component words. That's usually pretty easy, even for non-native speakers (see VLIW entry for examples), but there are special cases that can trip one up. Words beginning with recht are one such case: they may be compounds of

  1. the adjective recht (`right,' in many of the English positional or geometric senses, and then some) like Rechteck (`rectangle');
  2. the directional adverb rechts (`to or on the right') like Rechtsabbieger (`a driver or vehicle that is turning right') or rechtshändig (`right-handed');
  3. the noun Recht (`law, justice') like rechtmäßig (`legal') or rechtfertigen (`to justify');
  4. the genitive form Rechts (`of the law') like Rechtsanwalt (translated as `lawyer' or `attorney');
  5. the adjective recht (`correct, honest') like rechtzeitig (`punctual') or Rechtschreibung.

Well, I ended up saying a little more than I had originally intended. That happens sometimes, and it can obscure the main point. Obviously, the various senses of recht, etc., are related and shade into one another, just as do the various senses of right and rights in English. The point, though, is that the ess following recht may be an inflection or may be the first letter of the next word in the compound. In principle, there might be a pair of distinct words like rechtsoof and rechtsoof, constructed with soof and oof respectively, but I can't come up with an example.

Until we have an entry for right, I'll add here that in Spanish, derecho has a melange of legal senses similar to recht in German. For example, it means `law' in general, as a branch of study or a system of concepts (a particular law is a ley), and also `right, prerogative.' By extension, it has the sense (usually in plural) of `duty,' or what one pays to exercise a legal privilege (e.g., derechos aduaneros). (I guess it's a bonus that `correct' in the most general sense is not one of its standard meanings.) What might be slightly confusing is that derecho is an adverb meaning `straight ahead' while derecha is a noun meaning `right' (i.e., a la derecha means `on [or to] the right'). [Okay, strictly speaking, many dictionaries still consider this to be not an instance of a noun derecha, but the noun phrase mano derecha (`right hand') with mano elided, but usage says different.]

RECOL
Reporting Economic Crime On-Line. A place to file fraud complaints discreetly. Administered by the NW4C and supported by the RCMP and others.

rect
RECTangle. A convenient building block for graphics and layout.

rectenna
RECTifying antENNA. For microwave-generating orbiting solar collectors (SPS: Satellite Power System), say, or RFID tags. Nothing but an antenna that receives power at a convenient frequency (in one of the ISM bands, typically), followed by a rectifying circuit to provide a voltage level.

The AC-to-DC power supply almost has a rectenna. It has a transformer with a primary winding that takes line current. This induces an alternating magnetic flux in the transformer core, which in turn (pardon the pun) induces an AC voltage in the secondary winding. The voltage across the secondary is put across a full-wave rectifier bridge (four diodes in obvious orientations) to produce a noisy DC signal. A capacitor shunt across the DC output functions as a primitive low-pass filter and gives a reasonably flat DC final output. That's the way it used to be, of course. Nowadays, there's fancy intelligent circuitry everywhere. Also nowadays, the final output can feed a lightweight supercapacitor, providing excellent surge protection.

The reason the secondary of a power transformer is not regarded as an element of a rectenna is that the mechanism of power transmission is mutual inductance. However, at high frequency, the mutual inductance has a pole (the pole is complex -- ordinary resistance in the circuit gives the pole frequency a nonzero but small imaginary part). In this region, the mathematical description of the power transmission between primary and secondary is equivalent to that of a transmitting and receiving antenna. Physically, the secondary is so close that one is not in the radiation regime, but from a circuit-designer's POV, that (i.e., the form of the signal variation in the vicinity of the receiving antenna) is not very relevant.

recto
An odd-numbered page, on the right-hand side (r.h.s.). From the Latin recto (ablative of rectus; I know what your filthy mind was imagining). Recto folio here meant `on the right page' as opposed to left page. Cf. verso.

It's not clear whether it is correct in English to use this terminology for books written in a right-to-left language. I found an interesting unintended solution of this problem at the Zimmerman library at UNM. They had a volume of Talmud (all Hebrew and Aramaic) bound upside down.

red
Communist (noun and adjective). Also socialist, or generally leftist. And no, I'm not going to explore the differences. European environmentalist parties are also generally on the left, but they are identified with the color green, sensibly enough. Left-wing coalitions that include them are called red-green coalitions.

In Germany in 2005, a new leftist party called the Linkspartei (`party of the left') won a small chunk of seats in parliamentary elections that yielded a muddled result. Neither of the two leading parties had enough seats to form a majority government without at least two of the three small parties, and one of the possible coalitions considered was among the SDP (main socialist party) with the Linkspartei and the Greens. This possibility was called red-red-green (rot-rot-grün). (Rot-grün-rot was less common, by a factor of ten or more. You'd think that might be because the Linkspartei won a few more seats than the Greens (54 to 51), but in fact the red-red-green order was widely used in political speculation long before the election, at times when the relative showings of the small parties -- and even whether the new party would win seats -- were uncertain. I guess it says something subtle about the German sense of proper color-word order.) In any case, the Linkspartei -- composed of the old PDS and former SPD socialists led by Oskar Lafontaine.

In the US, the color association of red with communism gave rise to the pejorative term pinko.

There's a book cleverly titled Red Blues: Voices from the Last Wave of Russian Immigrants, by Dennis Shasha and Marina Shron (New York: Holmes and Meier Publ., Inc., 2002). Mark Kopelev's story alone would make a good one-hour sit-com pilot.

It ought to be possible to do something funny with red-C and Red Sea, but I'll leave that as an exercise for the diligent reader.

red
Restricted EDitor. A version of the standard Unix line editor ed that is restricted in ways that protect security: shell commands cannot be executed (a bang prefix does this in ed) and only files in the current directory can be edited.

red
Spanish, `net.' Cognate with English reticule, a word which probably comes from some other Romance language.

red brass
A brass redder than yellow brass because it's mostly (say 85%) copper (Cu) and less zinc (Zn).

Hardened red brass with an 80/20 (Cu/Zn) composition has a density of 8.6 g/cc, a bulk modulus (E) of 100 GPa, shear modulus (G) of 39 GPa, and a Poisson's ratio v (nu) of 0.34.

red fat
No wait -- I think it's ``red. fat.'' Reduced fat.

redial, REDIAL
[This entry is special advanced information for the person who was trying to reach ``Michelle'' today at the Plexoft World Operations Central braintrust.]

If you reach a wrong number, then hang up and press REDIAL, you reach the same wrong number. Every time. It's been investigated both theoretically and experimentally, so you may as well resign yourself to it.

redox
REDuction-OXidation [reaction]. The unabbreviated name has the words in reverse order (``oxidation-reduction [reaction]''). It doesn't much matter, but I suspect the reason is something like this: English nouns, even abbreviated ones, tend to have initial stress, although reduction and oxidation are words with at most secondary stress on the initial syllable. An abbreviation like oxred would naturally have initial stress (on ox), and an unstressed second syllable. This weak stress would tend to make the e in red short. None of this is necessary -- a long e can occur in an unstressed syllable, and stress can occur on the second syllable of a noun (in most accents), but all other things being equal, this might be a tendency. It's also possible that the more common unabbreviated term was ``reduction-oxidation,'' but I doubt it: every oxidation implies a reduction, and vice versa. Before this was understood, and even since then, the most common way to describe an oxidation-reduction reaction, without using some abbreviated-word construct, was as an ``oxidation.''

When an atom is oxidized, its oxidation number increases. (Big surprise there, huh?) Oxidation number is essentially a measure of ionic charge, and since charge is conserved, every oxidation-number increase is accompanie
