Clearly it must be (left) noetherian! (Since we wouldn't want a ascending subnormal chain that doesn't stop where all of the elements are enjoyed by the larger ideals/submodules) :)

Sorry, writing "R is comm(unitive)" so many times can make you do things

A really beautiful piece by my former composition teacher. This is the one that really inspired me to someday compose my own music. Unfortunately, I lost contact with him after he had lost someone close to him I think, but I'm happy that he looks like he's doing well. Please enjoy!

Hello everyone,

There's a rhythm that I like but I'm not all too familiar with its name. Here are some examples:

• Doechii TinyDesk concert: https://youtu.be/-91vymvIH0c (22:56)
• DRUM GO DUM by KDA: https://youtu.be/VLE6Y1q13qE (2:53)
• Replay by Landon Conrath: https://youtu.be/m55UdZh4xXg (0:23)

It could be that they're not related at all and I just like hearing double time, but I think I've heard the term DnB before, but I've never had it properly defined. Thanks!

I don't know if the proof is right because answers to Rotman's exercises are hard to find (for me)

Tbh this should be marked as NSFW, math gore

EDIT: re-read it and I didn't mention that there are no factors that permute roots between g and h since the intersection of their Galois groups is trivial, also not sure if xi and gamma are even elements in the subgroup of S_n (they should be cause the proposition is true, idk how to explicitly show D:)

I don't know if I'm opening a can of worms here, and I'm still trying to backtrack a lot of history where I was tuning everything out. I keep seeing random swipes at Signal (or the representatives (?)), and I was wondering whether they are founded or just lies.Is it another situation like Lemmy where we just "take the technology and move on"? Thanks!

Oh Orespawn my beloved, it's times like these that I wish I cherished you a bit more

The math background needed to enjoy the video is not very extensive. Grant Sanderson (3blue1brown) explains everything to the best of his ability from a perspective of "discovering mathematics" and helping you "convince yourself" that you could have come to the same conclusion as well (i.e. grasping as much of the proof as you can). And if that goes over your head, then the animations are still really pretty!

My description:

An intreguing video that takes an innocuous problem of finding an inscribed square in a closed, continuous curve and connects it to familiar topologic objects, like the torus (or the coffee mug!), the Möbius strip, and the Klein bottle.

I swear @Blaze@feddit.org is everywhere bc he's here and I saw him in !linguistics_humor@sh.itjust.works and like two other communities 😭😭

Also just side ramble: lowkey this was kinda funny in a post-post-ironic way: first, it was meh funny because the guy rapping in such a shy voice was a bit funny and he's cute ig but NEXT; Second, the comment about the therapist genuinely made me cackle; third, and probably a bit more unfounded (?) is that the fact that multiple people can find this funny (the shared experience of laughing together?) ties off the humor with a bow and feeling of content fulfillment.

Slight context: bro was rapping the part of "DENIAL IS A RIVER" by doechii starting with "I mean fuck, I like pills" etc.

I just type random words sorry

The context behind this scene is hilarious, but it's like 151 chapters into the manhwa so I can't even explain why it's so funny
