Advanced math on Wikipedia is so annoying. Like I just want to know wtf a Hypergolic Vector Space is so I know whether it'll be worth my time to go learn about them, but instead the intro paragraph is a list of ever more abstract kinds of math that it's a subclass of until we hit group theory, and the article body is just a giant list of obscure properties.

Also, and this is not advanced math at all, the other day I needed the length of a chord in a circle, couldn't be assed to re-derive it myself, and thought this was basic enough that I should be able to just get it from wikipedia. But I was wrong because look how weird and useless the chord properties that make the cut are.
