Probe

Probe (pronounced prohb)

(1) To search into or examine thoroughly; question closely; an investigation, especially by a legislative committee, of suspected illegal activity.

(2) To examine or explore with or as if with a probe; the act of probing.

(3) A slender surgical instrument for exploring the depth or direction of a wound, sinus, or the like.

(4) In aerospace, an unmanned exploration spacecraft.

(5) A projecting, pipe-like device on a receiving aircraft used to make connection with and receive fuel from a tanker aircraft during refuelling in flight.

(6) A device, attached by cord to an oven that can be inserted into food so the oven shuts off when the desired internal temperature of the food is reached.

(7) In biochemistry, any identifiable substance that is used to detect, isolate, or identify another substance, as a labelled strand of DNA that hybridizes with its complementary RNA or a monoclonal antibody that combines with a specific protein.

(8) In electronics, a lead connecting to or containing a measuring or monitoring circuit used for testing; a conductor inserted into a waveguide or cavity resonator to provide coupling to an external circuit

1555–1565: From the Medieval Latin proba (examination (“test” in Late Latin)), derivative of probāre (to test, examine, prove), from probus (good).  The Spanish tienta (a surgeon's probe) came from tentar (try, test).  The dual meanings in Latin ((1) instrument for exploring wounds etc and (2) an examination) persist in English.  The sense "act of probing" is from 1890, from the verb; the figurative sense of "penetrating investigation" is from 1903.  The use to describe a "small, unmanned exploratory spacecraft" is attested from 1953; unrelated to this is the curious popularity of aliens subjecting humans to examinations with anal probes in stories of alien abduction.  Probe is a noun & verb, probing & probed are verbs, probeable is an adjective and probingly is an adverb; the noun plural is probes.

The Voyager 1 space probe launched by NASA in 1977.
Originally (with companion probe Voyager 2) a twelve-year mission, it’s expected to remain a functional scientific instrument until 2025 and is now some 24 billion km (15 billion miles) away, the most distant human-made object from Earth (only our radio waves have travelled further).  There are some who claim the probes have already reached inter-stellar space while other astronomers  maintain the edge of our solar system extends much further than was once thought and they're travelling still through a sort of cosmic limbo.  The Voyager probes, even after they're long inert, may continue their journeys for thousands or millions of years because, although the universe is a violent, destructive swirl, there is vast distance between threatening stuff.

Of the many inconsistencies in English spelling, none must be seem more mystifying to anyone learning the language than those words affected by the “mute e rule”: the inflections and derivatives formed from words ending in a “silent e”.  The question always is: to e or not to e?  Deciding whether to retain or omit the last letter is easier than once it was because dictionaries seem now to be more consistent in their approach, presumably one of the benefits of their shift to becoming on-line resources although, for historic reasons, we seem stuck with what seem ancient, arbitrary decisions such as ageing and icing continuing in peaceful co-existence.  So, there are words where centuries of particular spellings have become entrenched that to suggest a change would be absurd and that means any rule would have both examples which conform and those which defy.  Henry Fowler (1858–1933) in his A Dictionary of Modern English Usage (1926) acknowledged the impossibility of constructing a rule of absolute validity but as a guide offered (1) an indicative rule and (2) a guide to the exceptions.  The (1) rule was “when a suffix is added to a word ending in a mute e, the mute e should be dropped before a vowel but not before a consonant”.  The condition for (2) an exception was “the mute e should be kept even before a vowel if it is needed to indicate the soft sound of a preceding g or c or to distinguish a word from another with the same spelling”.  Probe is such an exception because if one has a probe, it’s helpful to know if something (or someone according to those who have been abducted by aliens) is probeable and that adjective can’t be spelled “probable” because that has another meaning.

The Mazda MX-6-based Ford Probe (1988-1997, left) and the car it was once mooted to replace, the long-serving “Fox” Mustang (1978-1993).

A competent, inoffensive coupé, the Ford Probe would probably have existed for a decade as a moderate success and then, having been discontinued without a direct replacement, been soon forgotten, had it not been for the furore which ensued when the idea surfaced it might be the company’s replacement for the Mustang.  In 1987, by means of a “controlled leak” the pro-Mustang faction (the beer drinkers) within the corporation let it be known Ford was planning to replace the Mustang with a modified version of a Mazda (championed by the chardonnay faction).  The reaction was vociferous & voluminous, Ford’s mailbox (and in 1987 mail came in envelopes with stamps attached) soon overflowing with complaints, the idea of a front-wheel-drive (FWD) Mustang anathematic, the absence of a V8 apparently beyond comprehension (although the Mustang II had suffered that fate in 1973-1975).  They also put their money where their poison pens were because the previously moribund sales of Mustangs suddenly spiked, the thought that this might be the last chance to buy a “proper” rear-wheel-drive (RWD), V8 powered Mustang enough to push the thing back up the sales chart.  The flow of letters and cash proved enough to persuade Ford and the platform was reprieved, the Mustang surviving to this day as a unique and highly profitable niche.  The Mazda co-project however was well advanced so the decision was taken to proceed and offer both and, badged as the Ford Probe, the modified Mazda lasted a decade-odd and it’s doubtful it cannibalized much of the Mustang’s market, its competition the other mid-sized, FWD Japanese coupés which had become popular.  A typical Japanese product, well engineered with a high build-quality, the Probe was a success (though it never realised Ford’s hopes in overseas markets) and when production ended, the only reason it wasn’t replaced was because the demographic buying the things had shifted to other segments, notably the sports utility vehicles (SUV) which would soon dominate.

1969 M-505 Adams Brothers Probe 16 (Durango 95)

The still controversial film A Clockwork Orange (1971) was based on the dystopian 1962 novel of the same name by Anthony Burgess (1917–1993).  At the time shocking in its depiction of violence, it's set some time in the future and as part of the verisimilitude the car used in the "driving scene" was a M-505 Adams Brothers Probe 16, one of three built.  Only 34 inches (864 mm) high (the prototype was 5 inches (125 mm) lower!), it emerged from the studios of the designers of the quirky Marcos sports cars which were idiosyncratic even by the standards of the cottage industry of low-volume sports cars which flourished in the UK until the early 1970s.  Although utterly impractical (passengers entered and exited through a sliding glass roof) it certainly looked futuristic but performance was disappointing because of the limited power. To create the mid-engined Probe, the designers used the engine and gearbox from the modest Austin 1800, moving the FWD package amidships, an approach later adopted by a number of manufacturers.  Had it been built using the mechanicals from the contemporary Cadillac Eldorado (which improbably had a 472 cubic inch (7.7 litre) V8 driving the front wheels through a chain-drive transaxle), assuming such a thing could be made to fit, it would have offered performance to match the promise of the looks.  In the film, the Probe was given the name “Durango 95” a name which seems to have chosen for no particular reason although the “95” may have been an allusion to 1995, decades away when the book was written.  Although A Clockwork Orange is perhaps not something with which manufacturers would like their products to be associated, many have since used the Durango name for a variety of purposes.

Newspaper headline writers like the word “probe”.  Within the industry, short, punchy words like “probe”, “jab”, “fix”, “bid” et al are part of a subset of English called “headline language”.
