Mathematical words outside of mathematics We've all heard expressions like "We need to factor this into the equation," where mathematical words have broader meanings than strictly mathematical. I'd like to develop a collection of such usages.  Of course, there's "grows exponentially" for just about any rapid growth, and "the rate has accelerated" not really meaning the third derivative.  Also, there's Friedman's cool usage of "orthogonal" at the Supreme Court (https://www.librarything.com/topic/193156).  Here's my two-part question: is there already list of such usages, somewhere? Can you contribute some examples?
 A: I've often wondered whether whoever created Delta Airlines' slogan
"Delta means change" had some mathematical training . . .
A: French intellectuals of a certain period made à la limite into a widespread idiom (or verbal tic) meaning, not just “borderline” or “in a pinch” as dictionaries say, but the taking of an argument to some sort of paroxystic or naked extreme. Random examples: from Philippe Sollers, Vérité de Barthes,

Myth is everywhere, it irradiates everything; in the limit, it talks to itself alone in our heads.

Or Jacques Andrieu, Psychologie de Mao Tsé-toung,

One can even say, in the limit, that only non-specialists can manage specialists. 

A: The mathematical word parameter has entered general English.  And its meaning has migrated, so that "parameter" now often simply means "a boundary or limit".
A: French has an expression "c'est epsilon" meaning something like
"it's negligible".  French 
wiktionary says this sense is "par extension" from the mathematical usage.
There's also lambda
"(Éthologie) Un membre considéré comme le plus ordinaire d’un ensemble",
which might have a mathematical origin.
A: A few more examples: infinite wealth, countless visits, uncountable advantages, success a function of hard work, appeal to the lowest common denominator, Venn diagram of circle A plus circle B.
