I hope they don't. The argument for removing it is basically that if you understand geometry, then the conclusion is obvious; but since this is an area where most people's understanding of geometry is incorrect (myself included, before today), the article is valuable. I don't see how it's different from articles on other mathematical paradoxes (Simpson's paradox, for example).

The same paradox is also featured prominently as part of a Mathologer video [0] and an article in Scientific American [1].

I love the Wikipedia animations -- they are usually extremely helpful -- but when I'm trying to read the article, I find them distracting. I usually move another window on top to obscure the animations so I can concentrate on the article. But there must be a better way. Is there a hotkey to stop animations? For Firefox in particular?

EDIT: I don't want to stop animations permanently with about:config; I just want to pause and un-pause.
