What does not-good mean?
[edit]The term not-good is used in the first sentence, but is not defined, is not a link and not mentioned again. 2A02:8071:3E81:1E20:B0DC:23D5:D783:FEFF (talk) 09:38, 10 June 2023 (UTC)
- I assume this is an old joke of some sort; in the same way that category theory used to be called "abstract nonsense" back in the day. ("Since this is a special case of a theorem from abstract nonsense, we can ...") When one first learns of maximal ideals that aren't made of prime ideals, one's mind goes "oooh, that's not good", and even if you accept nilradicals, the Jacobsen radicals feel even more not good. The definition would have to be some historical footnote of how these were perceived in earlier times. There's a injunction, though: "never explain a joke." linas (talk) 21:17, 4 April 2026 (UTC)
