Is that a crack on your favela tinshack?

>>12788210
it kinda does look like my favela

>>12788168
Its actually light dust, not air dust, notice how you never see it in the dark.

>>12788797
But it still exists, floats around, even without light I would guess. If not then that would be confusing & interesting
>>12788175
It's funny though how we live surrounded by this and it's relegated as something we see sometimes with sunlight

Average is anything from 4-6. Beauty is averaged at 5 with a standard deviation of about 1 (maybe 1.5). This woman is most definitely not 2-3 standard deviations high in the beauty department. At most she's 1 standard deviation above the mean, which is average beauty. She's a 6, and on a really good day at most a 7.

>>12788033
It's a parasocial relationship.
She's attractive-ish, in an unconventional way, and does the whole shy, awkward autistic thing, which makes her seem somewhat attainable to the simps, at least in their imagination.
Her simps could never, even in their imagination, see themselves with a genuine smokeshow like Nancy PI.

>a genuine smokeshow like Nancy PI
Nancy is 10x uglier tho

>>12788244
NanyPi is marginally more attractive. A stable 7, with is good without makeup. If she dolled herself up she'd be an 8. OPs girl is a stable 5-6, and if she tried really hard she maxes at a 7. NanyPi doesn't even need to try and she's a 7. That's the difference between being hot and being average.

Nut*

>>12788008
It is a delusion.

>>12788008
What causes post but clarity? The rejection of conjunctions I think

>>12788008
leading up to a nut your animal brain has been filling up with hormones to trigger arousal to a point of climax, dopamine is dropped and you're high off the release of stress.
it's all about the chemical triggers carried out unconsciously, like in extreme focus or fight/flight releases cortisol, you have an endorphin rush that builds up to orgasm and a refractory period (triggered by climax)
its similar to the action potential response, including the nut shiver some people get, which is multiple retriggering at that moment (and the point that pseudoscientists try to put their sex yoga in place) until the equivalent repolarization occurs. in that refractory period, if put in simple terms, your animal brain is returning to normal arousal, which when it overshoots gives a longer period where arousal is essentially shut down, even below your normal state of mind/"hornyness."
comparative animal biology goes over the importance of these sorts of hormone cascades during times of stress or arousal.

>>12789246
also what I mean with the shuttering is not "multiple orgasms like the woman's side where there are multiple retriggering, guys get one above the threshold for orgasm but it's extended with multiple cascades while staying beyond the threshold between nerves until hormones block it from firing in your head.

>>12787960
Why do you ask me, I'm just a humble shitposter.
Ask them fancypants over at /lit/

No, it's only the beginning

>>12787960
No. Even if you're the edgiest of reddit atheists, death is not the end. Provided you don't selfishly cremate yourself, your body will provide nutrients to the worms and bugs that live within the soil, growing existing life so that the ecosystem you reside in may continue. You give back to the earth just as you've taken from it your whole life. It's all cyclical, anon.

Smoke DMT to find out

I doubt anyone actually believes it is, even if it is.

Back when I was into bullet hell shooters, I used to warm up by running the game at 2x speed for a while, and then start my actual run at the original speed. The bullets seemed slower than usual and it was almost kinda spooky how effective it was. So yeah you definitely could experience more "things per second" if your brain was faster.

You've probably thought of the classic "does everyone see colours the same way?" question, but have you thought of "does everyone experience time at the same speed?"

This is why it’s difficult to swat a fly. They see things at a higher frame rate so experience time more slowly.

>>12787923
I'm pretty sure that basically is how it works. When I've used psychedelic drugs I've experienced time slow to a crawl because each passing moment comes cascading with signicantly more information than experiencing the world straight. Conversely, another phenomenon I've experienced while incredibly fatigued is that when I'm listening to music, even a song I know well, the song seems to be playing slightly faster and I suspect this is because the brain is processing far less info due to exhaustion.

>>12787923
I think that's what makes some professional athletes so good. Their reaction times are just a bit faster because their perception runs a bit faster, making the world around them seem slowe.r

>>12787923
Even if our universe worked purely by Newtonian mechanics rather than by general relativity, we would experience our surroundings in slow motion if we could run our brains faster.

>>12796837
Not sure if grey is the right word. It just doesn't really *pop* with color. By default it has the same lack of color as the emptiness when you don't imagine anything.

>>12796848
So what are you actually doing when you're imagining? Is it open or closed? Does it appear in your visual field and overtake the black or is it on a separate "plane" in your head? I've read people give different accounts on this, I guess because it's too difficult for people to describe personal experiences in a way that's understandable. For me everything I visualize is in the back of my head. It doesn't actually show up in my visual field, so if I closed my eyes it's just black, but I still "see" it. No issues with colors or keeping it together. Hard to describe.

>>12796853
Your description of it being in the back of the head makes sense to me. But if I focus enough on related memories I can get it appear in my visual field too I guess?

>>12796853
I have read that some people can actually superimpose their imagination on an empty sheet of paper or something. One has to wonder how many people are misdiagnosed as schizo or something just because they describe a normal visualization ability that the psych doesn't know about.

My ex had synesthesia and whe could recall dates easier by memorising the combination of colours of the digits.
I dont think there is any concrete evidence of photographic memory.

So i assume the current theories on memory are correct and you recall everything from paradigms you make. If you never pay attention to a minor detail it will never register in the list of paradigms in order to recall it

>>12788429
Stop confusing phenotype and genotype.
For the same reasons you cannot call each of your 46 chromosomes independent life forms is the same reason why plasmids are not independent living forms, you fucking dumbass.

The same reason you cannot call a mitochondria an independent living form anymore. It is part of the structure of a cell.

>>12788470
>at least a computer virus could conceivably build a computer with enough autism and automation
No, computer viruses are no different from memes.

>>12788472
a plasmid is not a chromosome
I literally have a diagram of a plasmid that reproduces outside of binary fission, INDEPENDENT of the host bacteria.

>>12787793
the best definition I've heard for life is :
"a chemical system that uses energy to keep itself from reaching chemical equilibrium"

here's an article with a bit more sophistication on the individuality(selfishness, living for the benefit of the cell or for self-replication) of DNA replicators and viral vehicles to explore the living-ness of viruses compared to other non-chromosomal DNA. transformation and plasmid-induced vehicles(conjugation) are inherently down to the cells consenting to pick up or send DNA so their mode of packaging is KEY to distinguishing an f plasmid from a virus in terms of movement and independence.
https://www.sciencedirect.com/science/article/pii/S1369848616300103
viruses are still not alive in a colloquial sense and fall in the quasi-living "certainly not rocks" camp.

Women still have one more hole: the vagina.
Men only have the anus and the urethra down there.

>>12788159

Vagina is not a hole, topologically speaking

>>12788161
Topologically speaking, how many holes does a man have? The mouth and nostrils seem to connect to the urethra and the anus. Ears and cornea appear independent. So three unique holes?

>>12788170
>seem to connect to the urethra and the anus

Not really, the anus is connected to the mouth and to the lungs.

Nostrils are connected to each other.

Eyes are tricky because if you consider the hole of the optic nerve then you'll have that the eyes are connected to the opening of the skull.

Urethra is not a hole but a cavity.

Nothing. If this were true the author would literally be the most powerful human on earth.

not everyone is stupid enough to care about education or jobs. if those things motivate you, you’re an NPC.

>>12789047
Wealth and success come from networking and lying/stealing - things only done by trash human beings. Your perception that they’re kind and smart is due to your own blind spots. A ‘kind’ successful person is ALWAYS manipulating you for some kind of gain. Poor people are morally justified in being rude.

>>12789047
To be fair successful people are almost always good looking, in other words leeches who have been handed everything by the world. Of course you’re gonna be kind and positive if none of the world’s insane suffering and unfairness has been inflicted on you. Does it even count as being kind or positive if you’re a lucky leech?
Part of the reason all smart people hate positive people is because they’re all fake. No one who has been exposed to the true nature of reality has a positive attitude. A positive attitude is a sure sign someone is a privileged rotting piece of dumpster trash who would start screaming to block it out if you forced them to hear about an atrocity. I’ve met a lot of positive people who suddenly turn very angry if you tell them about childhood cancer or something similarly evil. No one has the right to be positive unless they’ve faced evil.

Linear algebra is the study of linear functions. A function is linear iff it can be expressed as $f(x,y,z...) = ax+by+cz...+d$. Linear algebra is a subset of algebra and therefore studies the property of the field constituted by linear functions. Matrix algebra is identical to Linear algebra because any linear function can be expressed as a matrix. But I believe some low-effort courses marked as matrix algebra specifically deal with how to compute matrices rather than the understanding of the underlying system.

It helps to have friends to take care of you for the duration. It can be months.

from personal experience

Kratom, but its an addictive substance as well, but is helps getting trough hard days, and you can be functional. but its not for daily use. but if you have serieus withdrawal you need to find professional help.

Ketamine helped me trough a medium alcohol withdrawel, but i only did it in the evening while i had nothing to do.

I cant recommend these methods because changing from "high" doesn't change you, but it can help in difficult days, sometimes you just need to face the withdrawal.

>>12788087
sidenote: i only have experience with substance related addictions (benzo, alcohol, amphetamine , nicotine)

Yea just take some of whatever it is you're withdrawing from. Not only will you not be withdrawing anymore but you'll also be high/drunk/whatever

It's a model of microgravity, not microgravity. I'm not familiar with the intricacies of this approach, but by inspection the musculoskeletal response to reduced/zero stress on the limbs could be well modeled using it

You all should really look up the fact that the real reason of the sinking of venice is because of the aquifer beneath the swamp that venice is build on is sucked dry by surrounding industry.

>>12792344
This is a bait post but whatever.
The acquifer has been tapped from the 50s during the rapid industrial growth that all of Italy experienced, but the practice has been banned in the 70s, and yes the city sank because of that, and yes the city is still sinking due to subsidence. One of the proposals to patch things up is to pump water in the acquifer around the city in key locations over the period of a dozen years or so to raise it, but as far as I know it's still just one among many proposals and would be a palliative anyway. This doesn't change that sea level has been increasing steadily, plus acqua alta has been happening at alarmingly increasing rates with record breaking levels each time to the point they predict MOSE to become obsolete far quicker than predicted (not that the shitshow that is MOSE would last that long anyway), and all this can be tied to climate change. There are multiple measurements spanning more than a century on sea levels and through some analysis and more recent GPS measurements it has been possible to separate subsidence from eustatism, and guess what? The sea level IS rising. If you think that's it's just all a lobby sham and everyone's lying you should either go back to /pol/ or take your meds.

>>12789708
I did, but it's a rabbit hole of optimizations. Just doing a FEM is literally babby-tier, but then comes the isoparametric concept, sparse calculations, bandwidth optimization, problem detection like bad Jacobians, hourglassing, locking and mitigations like an extra energy term, and if course abstracting to allowing arbitrary elements to be used, hybrid elements..
That's where I stopped. I think it's necessary for every engineer to program FEM yourself at least once to understand it.

this, my best sleep was when i was a motivated kid who worked every day and was exhausted at 10 pm, fell right asleep, slept hard, and woke up at 6am naturally. worst sleep was when i became a loser who played vidya and jerked off all day and can stay up all night, take hours to fall asleep, and still am tired after 10 hours of poor sleep. been working harder lately and my sleep has been improving, at least on nights that i'm not stressed/anxious.
