Ad infinitum.
Ad infinitum是拉丁文常用短语,意“无限”、“永远”。
在上下文中通常意味“永远继续、没有限制”,可描述一永不终止的过程、一永不终止的重复过程、一永远重复的指令。类似于短语et cetera。
例子包括:“1, 2, 3, ... continues(继续) 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[1]
The mathematician
Augustus De Morgan included similar lines in his rhyme
Siphonaptera.
