Ok /sci/ question if I put something like water or liquid metal in a high pressure environment like really high what would happen would it float due to pressure and form a sphere or fall and flatten on the ground
>>8049755
You're gonna have to explain in more detail exactly what you are trying to do
>>8049755
If it's not a gas or a superfluid, it will stay down
Are you trying to lift your mom using some shenanigans OP?
If i was trying to lift my mom she would get crushed under the pressure and I don't wanna clean that up
If I were to visualize the fourth dimension, would I be able to "see" two dimensional objects, or would they appear as one dimensional objects are to us?
I see 2 side by side 3 dimensional objects.

>would they appear as one dimensional objects
No. In that case you'd be viewing a different plane of the third dimension as it intersects the fourth.
Do you think reality is an illusion?
>>8049606
fuck, that's noumenality

There's no illusion without a reality.

I only heard about this on the news recently and they were all "best place to look for life" but then
>Although they orbit very close to their host dwarf star, the inner two planets only receive four times and twice, respectively, the amount of radiation received by the Earth, because their star is much fainter than the Sun. That puts them closer to the star than the so-called habitable zone for this system, defined as having surface temperatures where liquid water can exist, although it is still possible that they possess potentially habitable regions on their surfaces. The third, outer, planet’s orbit is not yet well known, but it probably receives less radiation than the Earth does, but maybe still enough to lie within the habitable zone.
Which doesn't sound anywhere near as promising. Am I right in assuming this system is important because the planets are earth-sized and within roughly the right area and therefore other systems might be similar, or is there really any chance for life to develop on them?
>>8049312
>for life to develop
No, it's way too hot for that.
But it's nice because it's a dwarf star. That'll be very useful to us in a couple billion years because dwarf stars burn extremely slowly. If we can find any way to inhabit it at all, we'll have a home for a very, very long time.
Personally I favor gravitational nudging into the habitable zone. We have billions of years to get it right, so there's virtually no way to fail.
>>8049312
being habitable is just the beginning, they need loads of water and carbon and all that other shit that only Earth has

Why would you study physics when there exists theorems that contradict each other?
There are in every field. Its a testament to the imperfection of human knowledge and how much there is still to learn
>>8049182
> why would you study something if you don't know everything already?
Cool.
>>8049182
This is why we study applied math instead
How do I read faster without sacrificing comprehension? I can feel myself subvocalizing when I read, and my eye sometimes gets stuck on a word for a fraction of a second, which is annoying. I read faster than most folks, but I'd like to improve.

Put finger on page, trace the words you are reading.
Speed up the tracing until you can't keep up.
What also works is reading everything extremely quickly and multiple times

Please excuse my shameful ignorance, but this is something I've always wondered:
The set of all real numbers is infinite.
The set of all prime numbers is also infinite.
Yet the set of all prime numbers is a subset of the set of all real numbers.
But how can there be more real numbers than prime numbers if there are an infinite number of both of them?
doesn't know the difference between countable and uncountable infinity
>>8048942
>more
There aren't more. More implies a quantity. We're not dealing with quantities, we're dealing with set cardinality. The basic premise is the one grows an infinite ratio faster than the other.

Why do I get otherwise..?
I'm not looking for a graphical approach, I'm more so wondering why my mathematical approach is wrong
>>8048938
for starters, it looked like you multiplied wrong the first term in the expansion
>>8048943
my bad, there's supposed to be a cosine in there too, but i miscopied it from my scrap paper
What are mathematicians trying to accomplish using stuff like using Calabi-Yau manifolds, let alone discovering them?
It seems to me you are just making things /extremely/ and needlessly complicated.
I'm beginning to think all this is just a competition to prove how much you "know" (regardless if that knowledge is just a complication) and a way to give yourself an excuse to find problems which have really no bearing on reality.
You cannot honestly tell me that these "manifolds" do or mean anything. Please don't tell me this...

Explain different types of infinity to me, /sci/.
>>8048797
Assume the axiom of infinite. You now have a valid system for saying two infinite sets have different cardinality.
You can also assume the logical opposite and the logic will still work.
>>8048804
So, in theory, one could assume that literally every conceivable thing exists, due to the nature of infinity?

Quantify that. How long have they been "dead"?

Does snorting Melatonin (Insufflating) deliver more to your brain than just taking it orally?
I've done it a few times, and it burns like hell; I wouldn't recommend doing it. I just want to know if it actually does make me sleep better than taking it normally.
Check the bio availability of it insinuated vs oral investment. see which has the bigger bang for it's buck
>>8048732
yo mom, i'm trying to sleep real fast. crush up a line of melatonin, will'ya?
its a hormone, i dont think it crosses the BBB
Is autism an inherently genetic disorder or can it be aquired trough one's lifetime?
genetic
you aren't autistic anon if you were you wouldn't have the social grace to ask
Probably mostly genetic. Some studies have some correlation with outside factors like early childhood and upbringing, but nothing is conclusive. It defiantly can't develop later in life.
if it's genetic than how did it start?
Taking an accuplacer in a few weeks, haven't been in a classroom in a few years. What books/tools can I use to refresh myself in math?

Thanks, man.
