fien - she/her - doing theoretical physics but my heart yearns for math - personal posts at #String::from

[mathamatacs]

been feeling kinda negative after i acquired a minus sign. hope it's just a phase

moving into a non-abelian accommodation such that you don't have to commute

I'm no algebraist by any means and I'm about to embark on a journey of sheaves and honestly? It looks scary

I also read that there is such thing as cohomology of sheaves with coefficients

in sheaves

God help me. If anyone has any recommendations for books on sheaves with focus on (differential) topology I'd greatly appreciate them.

[sapphic-adjunction-deactivated2]

Sheaf cohomology with sheaf coefficients..... neat.

The first simulated image of a black hole was calculated with an IBM 7040 computer using 1960 punch cards and hand-plotted by French astrophysicist Jean-Pierre Luminet in 1978.

[str-ngeloop]

the romance of hand-plotting. this guy looked at the numbers and drew each of those dots manually, and the image emerged. we can only imagine how he felt

Proof by induction?

No. Proof by conduction. I want my proof to be so good it shocks you.

[newtonian-derivation-sucks]

my proof by induction clocks in at 22 henries

Something about maths that'll never not amaze me is how sometimes you'll read a certain topic and it'll be kinda out of reach, like you kinda get the idea but the details go over your head. But then a few months later you'll come back to it and somehow it makes so much more sense. Maybe it's cause you've realised something that makes it click or sometimes you'll have learnt other things and it'll put it in a new perspective. And it's honestly one of the best feelings

[onrtrp]

have you sheft your sheaves today?

[galois-groupie]

have you stacked your stacks today?

[proof-by-intimidation]

have you schemed your schemes today?

A LaTeX mod to draw coffee cup rings on your technical papers

LaTeX is the venerable, gold-standard layout package favored for scholarly papers, especially technical papers; back in 2009, Hanno Rein released LaTeX Coffee Stains, an extension to draw a variety of coffee-cup rings on your paper; the code has been improved by community contributions over the years and is very robust and full-featured! (via Evil Mad Scientist Labs)

You’ll ask an algebraic geometer what a topological space is and they’ll go on a tangent about how really a topological space is just something you can put a sheaf on and that a sheaf is really just something that gives you a good cohomology so really what you should be asking is what is cohomology and then not answer the question.

everytime i open ncatlab its a whole new experience

Can't wait for the Pope's official stance on the smallest element of ℕ and the subsequent schism

[skerzando]

[anremithrl]

Honestly, we need someone to answer this question. What the Pope's opinion on Natural Numbers is.

Can we just ask?

[positively-knotted]

By virtue of being the pope, he is basically Italian, which is basically Fr*nch

[nb-swordk9]

Shit man, this math war is fucked. I just saw a guy draw a commutative diagram and say "one point compactification" or some similar shit, and everyone around him got folded into a 3-sphere and vanished into 4d-space. The camera didn't even go onto him, that's how common shit like this is. My ass is casting ε-δ and quotient spaces. I think I just heard "infinity-groupoid coskeleton tower" two groups over. I gotta get the fuck outta here.
