I love Twitter for amplifying the most brainlet takes under the sun. If sum notation in math is to hard to understand unironically get the frick out of math.

I saw this on Twitter yesterday, very relevant

Arent those integrals divergent?

Im not gonna do the msth but they look divergent also the notatuon is wrong

first one i dont know enough about tensor calc but the second line looks like a standard gaussian to me and first noticing the integrand is even and then doing the whole fubini theorem trick

The second one diverges so you cant integrate it defined

this absolutely perfectly describes my attempt to understand category theory

dumbest mechanic :marseymechanic: :marseykingcrown:

you inspired me to mull over ncatlab [1, 2] for an hour

i think i'm starting to get it, the contravariance jibes with the probing analogy

but did they really switch from an example with notation X↦[X,ℬ nU(1)] to an example with notation U↦[U,X] :marseyretard:

I’m absolutely hopeless. I was trying to understand topoi and I don’t remember why. I think it was some nerdy gay foundations shit.

Category theory is extremely important for :marseymechanic:

(Actually that second link is pretty helpful now that I’ve taken the time to read it, that’s a really good explanation, I’m now closer to understanding that I will never understand sheaves tyvm)

Its stacks of sheaves all the way down. The fact that more than 0 people here know sheaves is alarming at best.

What if plus signs are too hard to understand too? Math needs to stop ableistly gatekeeping people of sub-80 IQ.

Lol nvm actually let these morons have degrees in math without understanding basic notation, only gonna accelerate how little a degree means

Implying a degree means anything anymore, has been like this for years already

the only point of my math degree is to prove im not a mouthbreather who did poli sci or some shit, plz dont take that away form me

You can denote the additive operation in a field with any symbol you want bro

field

just use a ring bro, you dont need a whole field

Back to fundamentals. Addition as set operations on sets containing the empty set
