Welcome to c/science_memes @ Mander.xyz!

A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.



Rules

  1. Don't throw mud. Behave like an intellectual and remember the human.
  2. Keep it rooted (on topic).
  3. No spam.
  4. Infographics welcome, get schooled.

This is a science community. We use the Dawkins definition of meme.

But more importantly, calling any indentation a "hole" is a case of specifically ignoring the special significance of actual holes. You can't pass through an indentation.

Guess I can't dig holes either

Sure you can, they just gotta come out the other side. Otherwise it's just a fancy divot

Watch out, we got a badass over here

please dont be mean I was trying to be gangsta ok

im white and in my 40s

There's a Weird Al song about you. Or three.

[–] sauerkrautsaul@lemmus.org 1 points 1 month ago

I actually grew up listening to weird al. I think "dare to be stupid" is maybe about me

[–] SpaceNoodle@lemmy.world 0 points 2 months ago (1 children)

Me, too, which is why I don't say silly things like that

well I been learned, thank you. im a smarter, wiser, and better person now due to your tutelage 🙏

edit: spelling (of course)

Shame on you for wanting to have fun in a meme post! Shame, I say!

[–] sauerkrautsaul@lemmus.org 2 points 1 month ago

its like going to the airport and hoping to really enjoy your morning

If you were to tell an average English speaker that you were going to dig an indentation, chances are high that they would misinterpret your meaning.

On the other hand, if you told them that you were going to dig a "blind hole," I imagine they would have a much better understanding of your meaning and you would still be technically correct.

[–] SpaceNoodle@lemmy.world 8 points 2 months ago (1 children)

That's part of why I try not to talk to average English speakers

[–] aMockTie@piefed.world 2 points 2 months ago

Haha fair enough

That's why we have the compound word "through-hole".

90% of important parts on living things are pockets and manipulations of surface area, two things completely ignored by topology. Topology is interesting mathematically, and has meaning for traversal and knot problems, but it's not really useful to describe reality.

[–] kogasa@programming.dev 6 points 2 months ago

Topology is immensely useful to describe reality.

[–] SpaceNoodle@lemmy.world 3 points 2 months ago

That's why we have a diverse set of words such as "divot," "indentation," "pit," "well," and so much more!

Topology is a component of the language called "mathematics" we use to understand, describe, and model reality in concrete terms.

[–] myslsl@lemmy.world 3 points 2 months ago

but it's not really useful to describe reality.

This is just not true.

What topology does for people practically, is it allows them to do a rough kind of geometric reasoning in a wide variety of cases. Further, the geometric notions defined via topology subsume many of the more intuitive notions you might already know of from the number line or the plane.

For example, continuity of functions, convergence of sequences, interiors and boundaries of sets, connectedness and many other things are inherently topological notions that any person who has taken a typical calculus sequence should have some intuitive idea of.

One of the biggest difference between actual pure topology and analysis is that analysis is just done in the context of really nice types of topological spaces called metric spaces in which notions of distance are available.

Any time people are using results of calculus in the sciences, under the hood they are using details about topology on R^n.
