Psychology and psychiatry are both pseudo-sciences that engage in nothing but projection and bulverism.

The fact is that many famous intellectuals displayed all sorts of behavioral patterns society at large didn't like.

The very idea that everything people don't like are diseases, disorders, etc... is without merit (as of yet).

The majority of APA members even take issue with many of the diagnostics concepts in the DSM.

There is a reason why the lead editor the DSM quit his job, and why the inventor of some DSM terms (ADD for instance) also quit his job.

There is too much false equivocation and bulverism in the diagnostic and description fields of psychiatry and psychology.
>>
>>8656272
I'm well aware of that, in fact i agree all the diagnostic labels are kinda bullshit, not only for the "etiquette" they establish on people, but also to make this discipline a more easy, experimental-medic approach to be considered a science like medicine or maths.
I believe eache person has its own form of living and behaving, and that is my opinion on psychology. The thing is, for this question i used the label to just generalize a behaviour so someone could answer my question.
What i know until now, is that someone who suffers from cronical sadness have their hipocampus slighty injured, leading to possible memory loss and other features that includes a discapacity of emocional, social and rational intelligence. So, im hoping if someone could explain to me the physical changes inside the brain, since the cognitive changes are quite-to-be known.

what i mean is that, when we die, its usually a horrific process and our bodies hold onto life until the bitter end, even long after the prospect of spreading ones seed could hold any benefit for the species. So why cant our bodies just sense when were "on our last legs", and just simply "turn off" or at the very least give us some sort of subconscious option to just drift away peacefully. Really seems like a logical next step. Why is life so afraid of death?

No evolutionary pressure for peaceful death, or great longevity for that matter. Anything that happens after we've passed on our genes and raised our offspring can't be selected for.

Why is life so afraid of death?
Why is being, a snapshot of something that's able to perpetuate itself with nuanced energetic changes, afraid of becoming the sole thing it set itself apart of.
Would you want to go back to the fucked up parents that locked you in the basement as a child after you've grown into an adult and have a relatively normal life?
And we do have comfortable ways to die, we just don't want to die per se.

Hear me out: The Earth's spin is the most abundant source of free energy we could harness. It wouldn't be easy, but it would definitely be worthwhile.

All we would need is something independent of the Earth's rotation on one of the poles. Like a giant gyroscope on the North pole, for instance. Then we just put a generator there and run a cable from there to somewhere else on the globe. We can even output the electricity using the cable!

Why don't we do this, /sci/? It's free energy.

>>8655866
Gyroscopes aren't "independent" of Earth's rotation. They rotational motion just contains a whole bunch of linear momentum of material points which makes it so it hates changing positions.

Every gyroscope will stop working with time and force applied. You can ideally get about as much energy out of it as you put into rotating it.

Is it possible for 3-dimensional beings that exist within an n-dimensional universe (n>4) to build 4-dimensional objects?
Assuming the existence of non-baryonic matter, and matter with negative or imaginary mass. What i'm vaguely picturing is folding the 3-d space and combining 3-d objects in a certain direction through the 4th dimension. When I mention dimension, I am excluding time.

An isosceles triangle is drawn around a circle. Prove that the triangle is also an equilateral triangle assuming that the area of the triangle is the smallest area possible.

I enjoyed this one so I thought I'd share it here. It's quite hard.
33 posts and 11 images submitted.

honestly that sounds like a proof that could be done just by deriving an equation for the area and doing some calculus for the minimum.
Ugly as fuck and maybe it turns out it you get some equations which are really hard to solve but there's a good chance it's pretty easy.
>>
>>8655721
The hardest part here is deriving the equation.
>>
>>8655714
Easy. Suppose it's not equilateral, then one of the bases is not tangent to the circle. Therefore is not smallest possible area.

>your undergrad doesn't matter! Grad school is what matters

How many of you little brainlets still delude yourselves with this sort of thinking? Daily reminder that if you go to a mediocre state school, you will NEVER attend a top tier school, regardless of how good your grades are, how good your test scores are, and how good your research is.

https://mobile.nytimes.com/2014/08/03/education/edlife/why-you-cant-catch-up.html?_r=0&referrer=

>The reasons for the disparity are easy to track, said Christopher Avery, a professor of public policy at Harvard’s John F. Kennedy School of Government who has written extensively on college as an agent of social mobility. Students who earn a degree from an elite college, even those with unimpressive grades and test scores, are simply too far ahead of those who don’t, he said.


>What’s disturbing about this research is that it shows that even if you distinguish yourself as a great student at a Tier 4 school, and by some miracle you get into a good grad program, you aren’t likely to wind up with the tools you need to ever catch up to those people who went to a more selective four-year college,” Dr. Avery said. “You want to think that at some point the playing field is level, but the truth is increasingly clear that the answer is it probably never is. By high school, it’s pretty much over.

Also, quotes from hiring managers at big engineering companies when it comes to hiring, on quora:

>"I'll be blunt:if you are committed to doing EE, you absolutely must graduate from Berkeley or another top school."
>"If you're interested in startup companies, (and didn't go to a top tier school) many won't even look at your resume: they've got so many coming in from the top schools, it's not worth their time.
>"School is the first thing I look at. You mentioned CSULB. A 4.0 from that school would be competitive with a sub-3.0 from top UCs, such as UCLA, or Berkeley"

Where were you when non-top tier school cucks got BTFO?

My cousin was literally just accepted to Oxford and his undergrad education was in the states at a mediocre university.
Don't get pissed because you failed to get into a decent college.
>>
>>8655690
I went to an elite Ivy League school, but you're wrong. I've been to a lot of PhD recruitment weekends for elite programs and the composition of the recruits was about 50/50 elite schools/non-elite schools. Once you are older and out of undergrad you will realize it's not as important.

Also, still OP here:

Feels good not to be a state school cuck

Oh, the job market is looking fucking great.
Here, this is a search engine for jobs. For you I picked the key words "physics-theoretical", checked all levels of education from "current undergrad" to "PhD", checked "any location", pick the sectors "academia" and "industry" and VOILA

Just pick which job would you like the most:

>>8655470
Depends what you mean by "looking for a theoretical physicist". If you want a job with a job title of "theoretical physicist" then no, there is no job market. However you'll almost certainly be employable in some other position with some other title.

Utilized adderall quite frequently in undergrad because it was readily available.

I can study normally, or study an insane amount of material and have the motivation to continue without any breaks for 12 hours and retain it

I went to Stanford in 2006-2010 and adderall was being sold in every dorm and commons.
I had to pay a friend whom paid the supplier whom would place the adderall in a ziplock bag and place it in my cars gas nozzle compartment
