A supposed behavior of alpha particles interacting with electrons in a magnetic field, reported by Bergen Davis and Arthur H. Barnes in 1929 and later identified as observational error rather than a real phenomenon. Now used in philosophy of science as a textbook example of pathological science — research that produces results no one else can reproduce.
“Irving Langmuir cited the Davis-Barnes effect in his famous 1953 lecture on pathological science alongside N-rays and polywater.”
Origin: Named after Columbia physicists Bergen Davis and Arthur H. Barnes who reported the effect in Physical Review in 1929; debunked within five years.
The trade and physical work of a blocklayer — installing concrete masonry units (CMUs), cinder blocks, or breeze blocks in courses to build walls, foundations, or structural elements. Distinguished from bricklaying primarily by unit size and the heavier mortar joints involved.
“Forty years of blocklaying had given his hands the permanent calluses and crooked thumbs of the trade.”
Origin: Compound of "block" + "-laying," parallel to "bricklaying"; entered trade vocabulary in the early 20th century as concrete masonry units displaced solid stone in commercial construction.
Standard scholarly abbreviation for "college," "collected," or "collection," depending on context. In academic citations it most often expands to "Collected" (as in "Coll.

“The bibliography listed the source as Coll. Works, vol. III, p. 412.”
Origin: Latin abbreviation, in continuous scholarly use since at least the 16th century; appears in early Latin printed books and was carried into modern English citation practice.
A noun, alternative spelling of "bitchsuit" — informal slang for an outfit (typically a sharp tailored suit or formal dress) deliberately worn to project authority, intimidation, or unapproachable competence. Most commonly used of women in male-dominated professional settings, though gender-neutral variants exist.
“She put on the bitch suit before depositions; the partners had stopped interrupting her after the first week.”
Origin: Modern American workplace slang; gained currency in the 2010s as a humorous reframing of "power suit" for women navigating hostile professional environments.
The warmth of the sun in winter, or the pleasant feeling of sitting in sunlight on a cold day.

Origin: Coined in 1964 by Australian scientists Bear and Thomas in Nature; from Greek petra (stone) and ichor (fluid of the gods).
A shrewd, unprincipled politician — one who places personal ambition above party loyalty or public good and uses oratorical skill to disguise the absence of conviction.
“Truman publicly defined a snollygoster as 'a man born of an assumption of office without regard to party loyalty,' clearly aiming at a contemporary.”
Origin: American English, mid-19th century; possibly from Pennsylvania Dutch schnelle Geister (quick spirits) or simply coined for sound; used by President Truman in a 1952 speech.
A person who presumes to give opinions beyond their expertise; someone who offers advice on matters they know nothing about.

A misinterpreted phrase that sounds plausible because the substituted word makes a kind of sense — for instance, 'old-timers' disease' for 'Alzheimer's disease,' or 'for all intensive purposes' for 'for all intents and purposes.'
“The phrase 'duck tape' is technically an eggcorn that won — it's now a registered trademark.”
Origin: Coined by linguist Geoffrey Pullum in 2003 on Language Log, after a writer's substitution of 'eggcorn' for 'acorn'; the term itself demonstrates the phenomenon.

The vertical groove between the base of the nose and the border of the upper lip. A normal anatomical feature in primates; abnormalities in its formation can indicate certain genetic conditions.
“Pediatricians check the philtrum when evaluating for fetal alcohol syndrome — a smooth or absent groove can be one indicator.”
Origin: From Greek philtron, originally meaning 'love charm'; the anatomical sense developed from a folk belief that the groove was the residue of an angel's silencing finger pressed there before birth.
An abnormal, persistent, and unwarranted fear of failure. One of the longest single-fear phobia names in English.

Origin: Latin quincunx, originally a Roman bronze coin worth five-twelfths of an as, marked with a quincunx pattern of dots.

A hypothesized polymerized form of water proposed by Soviet scientists in the 1960s, claimed to be denser, more viscous, and stable up to 500°C. Subsequent investigation showed the samples were ordinary water contaminated by silica and other dissolved substances. Now a textbook example of pathological science.
“Polywater commanded serious research budgets on both sides of the Iron Curtain before being unmasked as a contamination artifact.”
Origin: Compound of poly- (many) + water; popularized in the late 1960s; debunked by the early 1970s.

Origin: From Latin sesquipedalis (a foot and a half long); coined by Horace in the Ars Poetica to mock pretentious dramatic vocabulary.
A nonexistent form of radiation reported in 1903 by French physicist René Blondlot, who claimed they were emitted by metals and could be focused by aluminum prisms. American physicist Robert W. Wood disproved the claim in 1904 by secretly removing the prism mid-experiment without affecting Blondlot's results — a now-classic case of pathological science.
“The n-rays affair is taught in physics history courses alongside polywater and the Davis-Barnes effect.”
Origin: Named for Nancy, France, where Blondlot worked; reported in academic physics journals 1903-1904.
