Ad infinitum is a Latin phrase meaning "to infinity" or "forevermore".
Description
In context, it usually means "continue forever, without limit" and this can be used to describe a non-terminating process, a non-terminating
repeating process, or a set of instructions to be repeated "forever," among other uses. It may also be used in a manner similar to the Latin phrase
et cetera to denote written words or a concept that continues for a lengthy period beyond what is shown. Examples include:
-
"The sequence 1, 2, 3, ... continues ad infinitum."
-
"The perimeter of a fractal may be iteratively drawn ad infinitum."
The 17th-century writer
Jonathan Swift incorporated the idea of
self-similarity in the following lines from his satirical poem
On Poetry: a Rhapsody (1733):
The vermin only teaze and pinch
Their foes superior by an inch.
So, naturalists observe, a flea
Has smaller fleas that on him prey;
And these have smaller still to bite 'em,
And so proceed ad infinitum.
Thus every poet, in his kind,
Is bit by him that comes behind
The mathematician Augustus De Morgan included similar lines in his rhyme
Siphonaptera.
