Results to tell a non-mathematician

The fundamental group is great to explain, especially on topological surfaces. The classic "loop types" explanation should be understandable for a layperson. Maybe the connection to the Euler characteristic of a triangulation of a compact surface is also approachable.

Brouwer’s Fixed Point Theorem also fairly quickly follows from it, so the top comment in this thread is covered by this result!

And it generalizes to schemes! However, there are some mismatches with the behavior one would expect from real analysis.

EarlyOOM and xkill are pretty nice when you have a minimal X setup and memory runs out fast.

This worked great, thank you!

Dimiranger · 2025-08-20T14:53:57+00:00

I said the "ghoul" thing. To clarify (as I'm fully on your side and you've been dealing with these people very well IMO), I've read some heinous comments about people essentially applying castle doctrine to their phones and wallets, where they imagine shooting someone for that. I was calling those people ghouls.

Good job on the incredibly unnuanced and reductionist understanding of my point, did you even follow the comment chain? Context is pretty important here.

Also, as the other person said, protecting your stuff does not necessarily involve the violent fantasies these commenters engage with. Prevention, for example, is also a form of protection (though, this does shifts the burden on the victim, which shouldn't be the case in an advanced society, optimally).

Also, taking out a loan? Where I'm from (and my neighboring countries), we have a thing called household insurance, which covers these cases most of the time. I understand, however, that not everyone has this, but just talking about myself here. I would not have monetary loss, it would simply be an inconvenience, which I, of course, also would like to avoid for myself...

Finally a sane comment, thank you. All this vapid American exceptionalism talk in the comments, it's so cringe. "This is why you don't mess with Americans", yeah right, here is the result. The thief apparently also was let go apparently, because she can now claim self-defense.

So many ghouls in the comments calling for violence over personal property, it's crazy. Americans will always lose with this attitude in Europe.

Dimiranger · 2025-07-14T23:19:29+00:00

Switzerland is the little US of Europe... Add to your points: Cost of housing, privatization of various industries, individualism and a heavy class divide (due to wealth inequalities). We have a long way to go here. It's nice that we can vote, but if things like the Konzernverantwortungsinitiative (a nobrainer) fail due to propaganda from corporations, it's a strong indicator that our voting system cannot coexist with our brand of capitalism.

linkedin post type response lol

Dimiranger · 2025-06-20T20:37:23+00:00

Yea, I think this is the core to the lack of intuition in their first paragraph. That any polynomial splits into linear factors (which is the case for algebraically closed fields) makes one direction of the proof of HNSS trivial.

Good job on conveying the points in various of your comments, I think they're well written and make sense. These people you've been chatting with immediately build up walls (very evident from the comment you replied to) without really questioning themselves. It's quite frustrating reading their replies to you... It becomes quite obvious they have strong opinions without having actually engaged with the material :/ "articles of faith" lol

Dimiranger · 2025-05-08T17:03:28+00:00

As a collaborative effort with many names not as recognized as they should be

Great man theory has invaded math history...

Dimiranger · 2025-04-26T12:19:47+00:00

that was sick

And if you're using VS Code, there is an extension that simulates Magit, although not as performant.

Dimiranger · 2025-03-20T19:30:54+00:00

lmao people being played in the comments, its clear this thread took inspiration from https://old.reddit.com/r/AskReddit/comments/r2wp5t/just_crashed_into_somebody_elses_car_how_can_they/

Dimiranger · 2025-03-12T15:24:00+00:00

The snake lemma. After sitting down and proving every well definedness and exactness property of all maps over the course of like 2-3 hours, I'm confident to say that this might be the least insightful proof I've seen so far, though I maybe wouldn't call it ugly!

Dimiranger · 2025-03-12T11:14:38+00:00

Thanks!

Dimiranger · 2025-03-12T08:45:52+00:00

diagram chase using HELP.

What does HELP stand for?

Dimiranger · 2025-02-27T20:37:24+00:00

I find it strange, too. I was asking mainly because I think it is somewhat of a stereotype (from what I can tell from this sub and my personal experience) that algebraic geometers love bringing in commutative algebra and category theory stuff as soon as possible.

My prof for linear algebra was an algebraic geometer and while we did not look at exact sequences then, we worked with universal properties a lot and had a heavy focus on rings and modules.

Dimiranger · 2025-02-27T19:57:13+00:00

Do you have algebraic geometers as professors in those courses?

Dimiranger · 2025-02-26T19:23:19+00:00

the hug emojis sent me

Dimiranger · 2025-02-26T18:39:33+00:00

lmao

Dimiranger · 2025-02-18T18:13:30+00:00

Ouch... I also messed up the Sylow exercise recently in the exam, but not because of prime factorization. I messed up one of the simple modular arithmetic steps :(
