Try holding an entire mug of coffee with a donut
Who the hell is asking coffee or a donut?
when someone at work is making a coffee run and can only afford one thing per person
Ya, give me both please.
It’s the same shape, just reshaped
genius!
They better all weigh the same.
Shape has little to do with mass. Unless you want it to be so.
Reminds me a bit of the evolution of the eye
Meanwhile, physicists: “Matter is basically just empty space and tiny particles moving very fast, a hole is just even emptier space”
Well, for one, that’s a coffee mug, not coffee. But I suppose coffee can also be in all of these shapes.
It’s asking about the coffee not the coffee cup.
If your coffee has a hole in it that’s weird.
I take my coffee black-hole seriously.
A black hole isn’t a hole.
Or is it? We don’t know what’s going on inside the singularity, it might as well actually be a hole in spacetime.
If it’s in space sure, but what if it’s on a person.
You could say the same thing about a bullet but a bullet isn’t a hole either.
Ah but you see, coffee in this mug would have a hole in it:
That’s one of those fun things until you have to clean it.
This looks like hell to clean
I could fuck that coffee cup.
Hmm, nice and warm
I believe you
Just enjoy the meme you fuckin nerd.
I can’t enjoy it if it’s obviously based on lies.
Plus look at that fucking coffee cup handle and tell me you like it, I dare you.
I had a very cool class in research epistemology and the exercise was basically to answer the question, do liquids have a shape and if yes, which is it? How would you prove it?
It was the source of the most deranged but valuable discussion I’ve ever had.
Isn’t part of the definition of liquid that it takes the form of its container?
I need another epistemological argument like I need another hole in my head.
One of them arguments was that in a vacuum, absent of any container or gravity, a liquid’s shape is that of a sphere.
Another one was that depending on the definition of liquid, liquids might or might not have a shape. This ranged from definitions of liquid based on atomic structure of molecules up to phenomenological definitions (asphalt and glass are liquids, according to some definitions e.g.). It also varies depending on the definition of the attribute shape itself.
The point of the exercise was to challenge the notion of objective truth in science.
Without gravity it’s a sphere, or in free fall without air drag it’s a sphere (if it has sufficient surface tension anyway, which is what makes lava or molasses flow that way, in combination with its viscosity).
But in a vacuum it will boil off until the vapor pressure is high enough to eliminate the vacuum. But then it’s not in a vacuum anymore.
Really a fluid or liquid will always try to minimize its surface area while fighting gravity.
It’s a definitions problem that a lot of people who think there aren’t “objective truths” in science.
Exactly, remember the point was not to be right. But to have the discussions. It wasn’t the physics we were interested in, but in the ways to construct knowledge. Definitions and models are human constructs. The universe doesn’t care that we do or do not have neat words and models of its workings. However, language and knowledge, as human endeavors, require human interaction.
An interesting one way to illustrate this point was: An hermit, all alone in the wilderness, by sole virtue of reasoning acquires absolute objective truth of the fundamental laws of the universe. Way beyond any current scientific knowledge. However, he doesn’t tell anyone. Has any knowledge been gained? If he dies, not telling anyone what he discovered, has any knowledge been lost?
It’s important to make sure our basic definitiins and assumptions are well defined… That being said I’ve always been pissed at epistomogists that opened the door to crackpots and manipulators to “define their own truth” and invite fascism.
I’m not saying epistomology is bad, but creating a debate about a well established fact is exactly what right-wing people will do when trying to impose their anti-scientific ideas.
Oh, please. Let’s not go there. Epistemologists have never suggested or promoted any such thing, your wariness is misplaced, it seems. If anything, fascism will use any and all rhetorical resource to promote their rise and stay in power. Remember, before post-modernism—which is the source of the “every person has their own truth” thing you dislike, not epistemology which predates post-modernism by a couple of centuries—fascism used objective truth as justification for the superiority of the in-group in power. Eugenics was touted by fascists in the 1800s as the epitome of scientific enlightenment. It was obvious and proven scientific knowledge that black people were an inferior race, etc. All the classical Nazi pseudo-arguments. A harsh and closed view of objective truth is precisely the kind of mindset where fascism thrive. Fascists like absolute truths quite a lot, even when they contradict each other.
The point of epistemology is to analyze the ways in which humans come up with and use knowledge. It has absolutely no prescriptive tenets at all. It is entirely descriptive.
Like, you can’t look at me in the eye and seriously suggest that Bertrand Russel, Jean-Paul Sartre, Locke, Hume or Immanuel Kant were fascists.
Yeah especially about things that are considered fundamental like the physics of fluids.
Unless they’re arguing about some quantum effect that hasn’t been proven maybe, but then they’re either a physicist or a Feynman bro who thinks they figured it out after “thinking hard about at and watching 7 hours of YouTube videos”.
If the “thread” width is around the size of an electron, then the coffee (liquid) has basically infinite hole.
The same applies to the cup, our hands and so on
Anybody ever think about how humans are just very oddly shaped donuts?
That’s not entirely true. We don’t have just one hole going through us. Our holes branch. We have 3 intakes (2 nostrils, 1 mouth) and 2 outputs (1 anus, 1 urethra). If you simplified us down topographically, it’d be like you formed a donut around a starfish with the arms sticking out and then you just deleted the starfish.
Considérons that our lungs and intestines are porous on a molecular scale… And also our sweat pores… Plus are blood vessels (connected to previously mentioned holes)…
Humans have a changing topology depending on the size scale at which you’re working.
I mean that is true of basically all structures and materials. It’s just the coastline problem. How long is the coastline? Depends on the level of precision you apply and the exact time you measure. Theoretically it is infinite if you keep getting more and more granular with it. That’s not helpful or meaningful for general purposes though.
We also have a bunch of doors on the holes.
So… you’re saying we’re houses.
…topologically. Geometrically, I’m more of a saggy tent myself
That’s Dr. House to you, dear fellow lemming.
Starfish are not a good example. They have no holes. Their mouth is their anus.
So starfish are closer to a doughnut than humans.
Yes, they are one hole away from a donut. If you include things like nostrils, ears and tear ducts then the internet says we have 7 holes.
You misread what I was describing.
“BEHOLD. A MAN!”
Go home, Diogenes!
drags a barrel in
BEHOLD, my HOME!
Ugh such a good video. Cya in 20 minutes
There’s a vsauce video about this
Anybody ever think about how donuts are just very oddly shaped humans?
Silly topologist.
Coffee is a liquid, it can adjust to any shape.
You must be shapeless, formless, like coffee. When you pour coffee in a cup, it becomes the cup. When you pour coffee in a bottle, it becomes the bottle. When you pour coffee in a teapot, it becomes the teapot. Coffee can flow and it can crash. Become like coffee my friend.

The ocean is the same as the Hadron Super-Collider, just reshaped.
I’m 50 and this is deep
This is exactly why my local Dunkin Donuts stopped serving topologists.
Same! Now they serve coffee and donuts instead.
Ha, if you can even call them that!
I see no coffee here.
Topology is one of those sciences that is hyper-niche to the point that it seems like it would have very limited scope, but when you take a closer look it’s actually studying something fundamental.
Are there any recent breakthroughs in topology I should be aware of?
I heard they found a new type of hole.
Other than black or ass?
No you mean not niche
