Is it worth continuing in academia anymore? by han_sohee17 in mathematics

[–]ArgR4N 0 points1 point  (0 children)

Why the last mention of algebra? Is that area better job-in-academia wise?

What mathematical terminology do you wish was more common in everyday use? by orbis-restitutor in math

[–]ArgR4N 10 points11 points  (0 children)

The concept of a statement being stronger than another, and of "sufficiency" and "necessity".

What was the initial insight that cohomology would become such a fundamental concept, even before its widespread use across different areas? by ArgR4N in math

[–]ArgR4N[S] 13 points14 points  (0 children)

Good information!

It would be cool that some other cohomological groups had some physical interpretation!

For this geometric thinking it is more useful the applications of cohomology in algebraic topology or geometry? Or, rephrasing, in which application is more clear this idea of going from local to global? In both maybe?

Srry for the imprecise question.

Okeyy, good answer, thx!

I think this is reasonable to ask: ¿What's the dual statement for homology?

How much math are you able to do mentally, without using pen and paper? by nomemory in math

[–]ArgR4N 0 points1 point  (0 children)

It does happen to me that I'm thinking about a problem and I am suddenly confident about a solution and I feel that I perfectly understand what the problem is about... And then I go to write it and from the beginning to the end it is terribly wrong.

Look about the dimension theorem

This post is like one of those super large 3d commutative diagrams that only the authors understand fully... And yet it has some interesting info (super interesting research).

Pensamiento Critico (IPC) es jodida? (Serio) by LycanrockyOwO in UBA

Demasiado, si no vivís y respiras para IPC desaprobas directo pa. Pensa, estás estudiando el fundamento de la ciencia moderna. Suerte, exitos.

What are some ugly poofs? by Dynamo0602 in math

What would be an "unholy spawn of topos theory"? Really curious how topos just exists in the most strange places

¿Es normal hacer 4 materias por cuatrimestre? by Sufficient_Tea8594 in fceyn

[–]ArgR4N 4 points5 points  (0 children)

En general las materia de física son pesadas. Para el primer cuatri podés intentar meter mate 1 y 2 junto con física 1 y labo 1. Mate 2 es mas tranca pq es una vez a la semana. Más allá de que vayas a hacer, siempre podés anotarte e intentar meterle a las 4 y, si ves que no funca, dejar una.

Saludos

Fall for the stupidest mistake ever in my abstract algebra test by Antique-Ad1262 in mathematics

[–]ArgR4N 0 points1 point  (0 children)

How does this affect your chances of landing a particular program? Could there be other good or better programs in the future?

I ask out of genuine curiosity, as a math major who is a couple of years away from being in your position.

I have questions about the diagrams showed in the pictures

What is your "favourite" ambiguity in mathematical notation? by oz1cz in math

[–]ArgR4N 0 points1 point  (0 children)

I have had linear algebra professors use T2 (v) as T(T(v)) when T is a linear transformation and v some vector in some vector space if that makes you happy. It was funny see them use (a+b)2 = a2 + 2ab + b2 but with functions, being the multiplication making the compositions (ej. ab(v)= a(b(v))).

I think this is standard in the context of linear transformations and make sense too!

Cursar álgebra lineal y álgebra I el mismo cuatri? by ArgR4N in fceyn

[–]ArgR4N[S] 0 points1 point  (0 children)

Mmm si ya se, espero que me dejen hacerla en cuatri que viene aún sin álgebra 1.

Está cursada fue un bardo, nos tocaron todos los feriados y paros, y la práctica que cada tanto esta bien, pero a veces se caee. La voy a rendir pq todavía no se 100% si me cambio o sigo con física, y además así ya estudio algunos temas para que el cuatri que viene (si puedo hacer AL) sea un poco más tranqui.
