Is mathematics invented or discovered?

... or more specifically, are the particular rules and laws and so forth invented or discovered?

We've had this thread so many times now.

The concepts and definitions are invented.

The relationships between them are discovered.

math is discovered
knowledge that is already true prior to being known cannot be invented
I never want to see this fucking thread again

The definition of "true" was invented.

what new anons?

Why can't you put submarines in underground acquifiers and explore them? Why can't people dive in them? Why can't I find any images of them?

There is far more groundwater in the world than above ground freshwater. Many civilisations rely on wells to give them all their water needs. So why can't you go underground and actually swim in the source of this water? It would likely be pitch black of course, but that would be rectified using lights.

I'm studying Earth science and the truth of the matter is we can. But they've got to be really really really really tiny. Really tiny.

I would say that the most common rock for an aquifer is sandstone. Between the grains of sand are spaces which can be infiltrated with water. If the pore spaces between mineral grains are too cemented together water can't infiltrate. We call that rock high porosity, low permeability. There are of course other aquifers than simply ones with highly porous mineral grains. Rock can have cracks which water can seep into which can create an aquifer that way.

If you want to 'dive' into something underground containing water we would no longer call that an aquifer. We call that an underground river and those do exist but by definition they are no longer aquifers.

They never try to understand why things are and they always memorise and accept what they are told like in maths they will just remember the method to solve certain problems but never ask why or attempt to understand why this solves it which inhibits their ability to actually get good at it

Aside from idiocy, why do some people, even the intelligent, refuse to believe things or choose to believe in improbable things in defiance of established facts?
15 posts and 1 images submitted.
>>
>>8754938

There are two, and only two, reasons people give to explain the seemingly intractable problem that, given access to the same information, two people can disagree: either the other person is stupid, and doesn't understand what the facts are, or, he is evil, and is either trolling you by pretending to believe something different, or is trying to trick other people into believing falsehoods for their own malign benefit.

This simple dichotomy of evil-or-dumb remains to this day the only explanation anyone ever has for this puzzle.

Notice that this is always framed in terms of "HE must be evil/dumb", not "maybe I'M evil/dumb". Afterall, /I/ hold the views I do because I follow reason and the facts, it's /HIM/ who is wrong, and /HIS/ wrongness that requires an explanation (evil or dumb).

To protect their own ego and self identity or group identity.

Simple psychology.

Hypothetical question for a story of mine.

Let's say in the future we can use gravitational technology. During high G maneuvers in space, would an opposite gravitational force opposite to direction of G force help the crew through the effects?

Pic unrelated.

With artificial gravity would passengers even feel the effects of inertia?

>>8754910
Wouldn't they?
>>
>>8754897

No, if you "pulled" in the other direction with "artificial gravity" then you would simply tear your crew in half. "Antigravity" won't work either, because gravity is only positive. Best solution: Put your crew into robot bodies BEFORE you send them into space.

Nucleus, nuclear membrane, cell wall, mitochondria, rhybosomes, telomeres.

I do remember the cell membrane is a lipid bilayer thats hydrophobic on the inside and hydrophilic on the outside.

Im studying maths and I want to start another degree. I dont have a job and I dont plan to get one (because Im a piece of shit that lives with his parents) and I have a lot of free time because Im fucking white so my IQ allows me to do STEM without a problem and also I dont have a social life.

So I decided to try something like botanics, gardening or some easy shit like those because they seem fun and they also have things like entomology and topography that I can later use to study biolulgy when I finish my maths degree because why not.

What you think bros ?

Seriously, you're getting way out of your math degree, just do it as a minor later on.

I bet you are studying pure maths and now you want to kys, move to applied topics like stats, cs, etc. and you will be fine doing a nice job while also doing that shit you like but shouldn't be a fucking career for the rest of your life.
