Isn't it weird how many people don't get just how weird it actually is to exist? I mean the odds are so ridiculous, it's amazing how unconscious most people are, worrying about trivial shit 24/7
sry that I ENJOY LIFE rather be a no life reading all these geek shit XD

DUDE WEED LMAO
Why is it that science accepts that height is genetic and that it differs from race to race, but chooses to not accept that intelligence is genetic and that it differs from race to race?
>>8206884
Is this topic the only thing you come to /sci/ for?
Because there are already studies showing differences in intelligence between races
Also because there aren't many people who will pay them to do so, and academia is not some magical holy grail of objectivity
Because it creates political friction and it's discussion is of no benefit - and really only relevant to Gorilla posting anons with superiority issues and his real life equivalents
Is there any truth to this?
....
ask a doctor, not some neckbeard
So I just watched Kahn Academys video on Maxwells Demon and its quite obvious how he proves it in regards of how the demon will expend create more heat than will flow from the cooler to the hotter body. And I also assume that this question has been asked and probably debunked multiple times before but here goes:
If you remove the demon from the equation and just say that by chance all high energy particles in the cold body move to the hot body and vice versa.
Obviously thats quite unlikely but maybe not even that unlikely if you only look at the first few moments (say a couple of nanoseconds) after the two bodies are brought together.
So by that logic in the unlikely case that happens, within the system there is a net decrease in Entropy, right? Now on the scale of the universe that chance obviously gets much much smaller because it would need to happen on enough occasions within a timeframe for at least 10^80 particles, but still: there would be a chance that the second law does not hold.
Where am I wrong?
>>8207488
The second law of thermodynamics requires a system to be in thermodynamic equilibrium. Strictly, probably nothing in our world is ever in proper equilibrium. The example you mentioned (bringing two objects together and looking at t=x nanoseconds) is definitely not an equilibrium situation. Also the entropy increase in the second law, is also obviously referring to timescales in which a system reaches equilibrium..
>>8207507
So could I say that is the system is at two points in time at an equilibrium down to planck lenghts, which is even more unlikely but still not impossible, and between those two points my high energy particles travel to the hotter body and vice versa, that the law was violated?
This will obviously never happen on the scale of the universe and within the lifespan of the universe, but just as a thought experiment.
Or is the planck length completely meaningless in that regard and a system can actually never be at equilibrium because even sub planck lengths of difference would mean its not?
It's changed somewhat because of the accelerating expansion of the universe, but yes it is _"_"_possible_"_"_ for entropy to only decrease starting tomorrow
are stars actually alive?

How the fuck am I supposed to filter out stupid shit like this?!

You can't. The best you can do is to no be autistic and get triggered by these threads.

Hey /sci/
I want to teach myself physics. I have no freaking idea where to start, I don't remember shit from high school. Math won't be a problem, I just finished my bachelor's in pure math.
Any tips on how to proceed? Thanks

>>8206617
Classical mechanics is just symplectic geometry on a cotangent bundle.
Special relativity is just Riemannian geometry with a metric of signature (1,3).
Babby QM is just projective unitary representations of Lie groups and algebras.
Congratulations, now you're ready to start with Folland's "Quantum Field Theory - A Tourist Guide for Mathematicians".

I honestly come to /sci/ just for the math, I'm not interested in science at all, only mathematics.
We could also allow homework helping, mathematics only, since most people are posting it here instead at /wsr. What are your thoughts?
>>8206591
my thoughts are that you're a fag!!!!!! and a retard!!!!!!, go away, do your summer assignments
if you need help with your homework find a tutor or work harder
gtfo
>>8206602
I don't want any homework help, I'm just sick of shitpost of /sci. Think about it, wouldn't it better to have a Math board?
>>8206591
OP, this board is only good for Math.
Hardly anyone on this board seems to understand science or have any significant level of scientific understanding.
This board should just be called 'Formal Logic and Shitposting' (FLS).
Can we harvest dark matter ? How do you get close and capture something that repels gravity ?
Also what are the possible applications of dark matter relating to space-time and dimensions ?
>>8206583
dark matter absorbs light
so it means,
the potential energy wich is it absorbed in it,it is the same as it could emits in form of heat
>>8206583
to get close to dark matter you need to travel at light speed in the deep space
so you will become light and get absorbed by it and die
>>8206583
Use a pokeball.
So are we just going to keep pretending there isn't a MAJOR problem of transitionary forms?
Since the 1960s, evolutionists have been promising that "tomorrow" we'll find transitionary forms, and they still aren't there.
Found a weird picture on the Internet
>>8206572
hmmm i wonder what this thread will turn into?
>>8206570
>So are we just going to keep pretending there isn't a MAJOR problem of transitionary forms?
There isn't.
>Since the 1960s, evolutionists have been promising that "tomorrow" we'll find transitionary forms, and they still aren't there.
They haven't.
OP, it's a wonderfully fortunate thing that we have any fossils all.
For a carcass to fossilize it must avoid being consumed or decomposing, before being rapidly buried.
It then must avoid erosion.
It's very rare in nature for this to happen, therefore fossils are actually quite rare despite being seemingly abundant.
However, we do not require a single fossil to confirm evolution; the genetic information of living animals alone provides significant evidence.
/SCI/ it's about time we talk about Mental Illness denial.
- Many Scientists believe Mental Illness does not exist
- Many Scientists reject the idea that all things labeled Mental Illnesses are brain diseases
- Many Scientists lump Psychiatry in with Psychology, Sociology, etc... and believe all Social Sciences/Medicines are the same
What do you think contributes to this anti-scientific belief among Scientists?
>>8206329
I don't think they reject the existence of a disease, but they reject the way in which psychiatric disorders are categorized.
There's a lack of study on the mechanics of the human brain. As soon as we can learn more about the human brain a more found science can be established.
Primary Counter Arguments
1. Intentional Misinformation
- Chemical imbalance is a hypothesis, not a working theory; never tested
- There is no data to support automatic lifelong diagnosis
- Less than 10% diagnosed agree, and most of those are non-delusional based diagnosis
- Genetics can at most account for only 13% diagnosed; prelimiary error % is high in a new science
- FMRIs have not been scientifcally proven to accurately diagnosis psychiatric 'diseases'
- The Disease Model of Behavior has not been proven and has obvious holes in it's reasoning
- Bulverism and Hyperbolic Discounting of Client Research, Testimony and Reasoning
- Overdiagnosis is serious issue tied to demand, control, obediance and personal incredulity
2.) Issues with Fallacies in the Diagnostic/Stigma Process
- Appeal to Stone
- Bulverism
- Argument from Report/Assertion
- Argument Circular Reporting

- Sedatives and Stimulants do not Correct, they Damage and Distract
- There has been zero proof or even proposed tests for the Chemical Imbalance Hypothesis
- Double Blind Diagnosis suggest "Suspicion Backtracking"; not "Specific Pathological Disease"

If I wanted to induce hypoglycemia (low blood sugar) quickly, painlessly, and with no sense of hunger, how would I do it?
Insulin seems like it would do the job, but injections aren't always painless, and an oral form doesn't seem to be available.
>>8206277
Drink a lot of vinegar, ~ 1 quart. Your tongue is hooked up to your gastic tract, this is why blood sugar rises in response to artificial sweeteners. If you give it something the opposite of sweet, your blood sugar will go down.
>>8206277
Can I ask why you would want to induce hypoglycemia?
How come when I'm upside down, my vision is upside down, but not my other senses?
{ your vision is not upside down , all your senses are upside down }
>>8206201
Is your vision upside down in zero gravity?
They are. You sense of balance would say you were upside down because gravity would be pulling on your inner ear and your flesh the wrong way.
As for hearing, if you were weightless and blind, the phase difference in your ears would always tell you the direction regardless, but if you had an alarm clock on a shelf and a cat meowing on the floor, the cat would seem to be on the shelf, and the alarm on the floor.
Our senses work together to make a picture in our heads, but for adults, the picture comes first, and the senses just update it. Being upside down doesn't take away your ability to orient that picture with your senses.

Does /sci/ realize that it is the dumb kid in school who would complain about learning something because they didn't know "when they would use it in real life"?
Your perspective is that bad
>Does /sci/ realize that it is the dumb kid in school who would complain about learning something because they didn't know "when they would use it in real life"?
Actually, that's what the smart kids said.
The dumb kids were always the collectivists that worshiped authoritarian groupthink and could never grasp why empiricism outranked conjecture.
Popper won numerous awards and is universally considered to be a genius by philosophers and scientists alike.
If you state empiricism isn't the only thing we have, then you have to provide proof that something is better.
Chances are you're an anti-science liberal arts douche; some radicalist that decided to come here to scream against facts because they don't fit your egotistical worldview.
Fuck you and your ego.
Proof for everyone else is all that matters.
It's always been that way and always will be.
Always.
