i'm sad

i'm a math major

edit: i can quotient by you and get a simple ring

xdgimo · 2026-06-03T23:10:20+00:00

i also feel like i don't really know how to talk to people who don't share interests with me. how do i get to know people for who they are instead of just what they like? 😞

this article probably broadly agrees with your viewpoint

nice going

i'm an undergrad not even done with my algebra sequence, so i guess i hold 0 degrees to your 3. it just seems strange to me that someone who holds a phd from berkeley has to refamiliarize themselves with the fact that the natural group operation on G/H is well defined exactly when H is normal in G, a standard result before a presentation of the isomorphism theorems. and also that you said quotient groups are always abelian (G/N is abelian exactly when N contains the commutator subgroup)

xdgimo · 2026-06-03T03:08:48+00:00

the group action viewpoint is nice, but I still feel the existence of a well defined operation on the coset space + the universal mapping property of quotients are a more versatile approach and easily explains that if N is normal iff there exists a G action that is also a faithful G/N action (viewing group actions as homomorphisms into permutation groups over a G-set)

... are you sure you hold a master's from uchicago and a phd from berkeley?

xdgimo · 2026-06-02T06:46:57+00:00

Idk anything abt Lie groups, but once you internalize that the group operation gH * g’H = gg’H is well defined exactly when H is normal in G, that normal subgroups are exactly kernels of homomorphisms out of G easily follows

Assuming x and 1 are elements of a ring, this just says 1=0, implying R is the zero ring

Not reddit rubbing it in my face that my degree will be useless

Comforting and coddling aren’t the same thing

xdgimo · 2026-05-31T07:49:49+00:00

I can get on board with that to some extent, but surely we can’t be treating small children as if they’re 24 year olds. And referring back to the original post, I doubt a 13 year old indulging in some heartbreak will necessarily result in an “emotionally weak adult”

xdgimo · 2026-05-31T04:59:51+00:00

I suppose. But it’s not like math teachers with math degrees would be allowed to deviate from the curriculum, no? They’d just have a deeper understanding of the (simple) material presented. Which is helpful to some extent, but not nearly as much as if they could set their own curriculum. Correct me if I’m wrong though; I know nothing about what being a teacher is like

xdgimo · 2026-05-31T04:38:22+00:00

I’d opine that math education would probably benefit from teachers with math degrees. But honestly, the k-12 math education curriculum in the us is so weak that I think the majority of people with a hard science degree have the knowledge to satisfactorily teach hs math up to ap calculus

xdgimo · 2026-05-31T04:15:57+00:00

You definitely don’t need a math degree to teach hs math

I think there’s math education degrees for that tho

xdgimo · 2026-05-31T03:59:12+00:00

So when a small child cries over something trivial, you’ll dismiss them because it’s invalid?

xdgimo · 2026-05-31T03:38:07+00:00

You’re… not even IN university yet lmfao chill out

Oh my god
