What does /sci/ think about quantum resurrection? Is it just pseudoscience?

It states that if time is infinite, and if the universe expands forever, due to quantum fluctuations, anything could pop into existence. It would take an extremely long amount of time, but given an infinite amount of time, you will re appear in the further (or at least a copy of "you" ).

Why don't other animals help other animals when they're in danger or in need?

If Africa was the cradle of humanity.... and black people have albino children every so often...

Was white society created by outcasts shunned from tribal Africa?

I've read shit that says even today albino children born in Africa are more likely to be thought of superstitiously. Like black cats on Halloween.

Is this the origin of white culture? A few albinos driven away from Africa?

If it was.... It would totally paint a very different picture of racial issues.

I need help, i'm having troubles getting the intuition behind top to bottom causation. Just the existence of said process is controversial, but let's assume it does in fact exist. How does it work? I can't get a sense of this.

A paper about this:

>A key assumption underlying most present day physical thought is the idea that causation is bottom
up all the way: particle physics underlies nuclear physics, nuclear physics underlies atomic physics,
atomic physics underlies chemistry, and so on. Thus all the higher level subjects are at least in
principle reducible to particle physics, which is therefore the only fundamental science; as famously
claimed by Dirac, chemistry is just an application of quantum physics. However there are many topics that one cannot understand by assuming this one-way flow of
causation. The flourishing subject of social neuroscience makes clear how social influences act down
on individual brain structure; studies in physiology demonstrate that downward causation is
necessary in understanding the heart, where this form of causation can be represented as the influences
of initial and boundary conditions on the solutions of the differential equations used to represent the
lower level processes; epigenetic studies demonstrate that biological development is crucially
shaped by the environment.

Thoughts?

What's /sci/'s opinion on psychology? How necessary is it in the medical field? And what do you think it can do to benefit/disadvantage society?

I'm a huge fuckin idiot who will go to great lengths to feel/seem smart, but then I realized I should learn shit. How did you guys get so smart? Does /sci/ have any suggestions or resources on how to get really good at math really fast?

. Is this truly a good book? I know it's held in high regard here, but for 150$ I'd rather it not be a meme.

Well?

Hello /sci/ I have noticed I am good at physics but bad at math, personally I have no idea why, I would consider myself smart and I solve math problems with ease the day I get introduced by them, but then after a week or two I can't remember how to solve the same kind of problems.

Could it be because I overestimate myself and think it is so easy I don't bother remembering it subconciuosly?

I do not have the same problem in physics at all but maybe it is because it is more logical than math.
