Why does the brain not differentiate between imagery and real life?

Anonymous Mon 12 Jul 14:05:09 2021 No.13384993 View Reply Original Report

Quoted By: >>13394029

A drawing can cause the same sexual reaction in a human just like a real person can. However, obsessing over 2D girls ensures that your lineage dies out, so it's a direct evolutionary disadvantage.
Why did the brain not adapt to this and keeps getting tricked by hot anime babes?

The female hyena has a clitoris, and like with humans this clitoris can swell when aroused which is basically an erection I guess.

Perhaps also interesting to know is that the clitoris of a female hyena swells up whenever she is ready to form a coalition with her relatives within a clan.

I'm asking because we were studying about differences between the animals caused by their sex, so I started thinking about the differences in male and female hyenas because they both have penises. (Well the female's one is a pseudo penis, so it's not a true one. Like one of the anons said it's a long clitoris. )

Spoilers regarding Stowaway, 2021 and 2001, 1968
When I was watching Stowaway, the part where she retrieved the LOX from the other end of the tethers, I was experiencing quintessential horror, dunno how, or why, but I think I never was more... not scared, more like afraid of "height" than in that scene. Can anybody tell me how they did it? I think it was an alright movie overall, but that part was just on par man...

In 2001 on the other hand I was just bored, I love Stanley Kubrik and I love slow movies, like Lawrence of Arabia, but when Poole drifted away, when David let off Poole, I felt nothing. I think the idea was that the Disco1 was like accelerating the entire time, hence unpowered objects drifting away... I mean there was no thrust visible over almost the entire movie, so god knows what pulled him away but Kubrik made an honest attempt to make sense of the physics...
Anyways this is like the big thing, both movies used the stellar diorama/the ship and nothing else there really for the sensation of motion. And while 2001 just showed something happening, the meere prospect of falling off that desolate booster on the other end, getting yeeted, the FUCK into the abyss- haunted me like for a week or so.

Please more of that!

From my understanding, DMT is just a fact acting potent psychedelic that just scrambles your brain's pattern recognition. In that scrambling, you try and find patterns in what is essentially random imagery that your mind is producing due to the drug. This is why different people see different things depending on what they believe in. A christian might see god, a Buddhist might see buddha, a schizo psychonaut might see machine elves, etc.

It's also not seeing into something supernatural, as the effects of the drug are consistent among humans. That's why images like the OP exist, they serve as a semi-accurate visual of the type of visual a human would see after smoking DMT, depending on their beliefs.

I would recommend watching this:

The guy also has a YouTube channel too:

He does come off as a bit schizo sometimes in other videos but good content overall.

For anyone here interested in actually learning about tensors:
As a mathematician and an EE the way phycisist talk linear/multilinear algebra is mostly obfuscating for me. And, in my experience, mathematicians and engineers seldom understand what they're talking about.
I believe this is because the terminology and approach is based on trying to achieve a "physical intuition" or something.
So, for those of us who don't give a flying fuck about that and who's training is very different from phycists', trying to read their material is mostly pointless.
Instead, I suggest looking at the literature commonly referenced by theoretical data scientists, mathematicians and engineers.
The following article is a great starting point for anyone looking to learn about tensors and who's already decently adept with linear algebra at the undergraduate level:

There are more than enough experimental physics in the world.

Dime in a dozen.

Each CERN experiment has hundreds of experimental fags working on it, doing mediocre menial labor.

But in the world there are not enough Theoretical Geniuses that can make revolutionary breakthrough in the Physics' backbone:
The Theory and its Mathematical framework.

Seems like too many people are trying to theorize about things that are simply too far out to prove. Theorists seem like they are just wasting their time on bullshit rather than focusing on what can actually be tested. Like with Witten hes going to keep believing in string theory no matter how many more colliders are built and fail to show any reason string theory exists.
