Quality thread you've got there, friend.
>>8689119
I was never a fan of those extrapolations, but it should be fairly obvious that blowing millions of tons of CO2 into he atmosphere and measurably changing the composition of it will have at least some global effects. Sure, it's uncomfortable as blowing CO2 into the atmosphere is kind of the foundation of modern civilization, but it is kind of plausible.
>>8689127
But can you prove that a wizard isn't removing all of the excess heat trapped by the greenhouse effect?
You cannot, marxist.

No one because if it were really the case we wouldn't still be associating geniuses with Einstein
Is our observable universe "shrinking"? Because the universe's expansion is exponential, it would make sense that space is being pushed away from us, thus our view of the universe is getting smaller.
>>8688926
yes
>>8688926
let me qualify my yes:
Yes, also you're tantamount to those annoying kids in class that ask questions they already know the answer to, or could just google but decide against it to get smart points instead
>>8688934
No, I wanted to hear some alternative view points.
/sci/,
I'm writing my master's thesis and I need to figure out a good measure of socioeconomic status for 15-17 year old high school students in America. I don't want to just ask about parent's income because they likely don't know and they obviously don't have enough education for that to be a factor. I'm thinking about a sliding scale of something like "the wealth of my family is higher/same/lower when compared to those around me." it's a subjective self-report so it's not that valid, but I can't think of anything better. Any advice, suggestions, or experience with these types of questions?
>tl;dr
>anon needs help asking how rich kids' parents are in a survey
bumb
will be monitoring this for the next 6 or 7 hours
Ask if their parents rent or own their homes, find out how large the house is, and how many cars they own. That will narrow it down a bit
>>8688792
Makes sense to ask about their parents. Know of another other proxy questions that get to the root of the question? I guess 'what is your parents education' is the most standard one

When it comes right down to it isn't everything either 100% or 0%. It's already been predetermined by the laws of math, chemistry and physics. Just because you aren't aware of every variable doesn't mean they don't exist. When you give a number other than 0% or 100% what you are really saying is the % of how sure you are. Coin flip outcomes are never random but based on a series of variables; size of the thumb, shape of the thumb, shape of the nail. position of coin on the nail, muscle force used, how far the thumb moved, tilt of the arm, wind resistance, ect. You could say "oh the movement the participant chooses to use is random but when it comes right down to it that's probably predetermined too.
probability is based on our limited knowledge
>>8687953
>When it comes right down to it isn't everything either 100% or 0%.
Everything believed is likely false.
Everything considerately and sincerely thought out is likely true or not far from it.
Lots of stuff is irrelevant.
Hypobaroc chambers are the best way to kill
They are cheap, fast and very painless
You reduce pressure so you the oxygen isn't able to penetrate into your blood
You don't feel unable to breath , just some headache and you laugh
Suddenly you pass out and die
(I experienced 3m of hypoxia in one of these and I didn't even notice it, while doctors said my oxygen was in 60% instead of 98% as usual)
Well and if they are bad guys, they can reduce pressure to almost cero to see how you shit your own intestines
>>8687661
Nah the headache comes after regaining blood O2 saturation, just like a hangover occurs after the drinking, not during.
Now if you're talking about state executions, a bullet would be cheaper and quicker, but that's my two cents. The whole pentobarbital injection thing is stupid expensive and is not as reliable.
>>8687685
>a bullet would be cheaper and quicker
But that wouldn't be "human".
OP makes a very good point.
You could execute a lot of prisoners in that chamber.
alternatively: convert a server room to a shower room and activate it's helium fire suppressant system
alternatively alternatively: shove them all into a hangar and give them a pack of cigarettes, which when lit will activate the foam fire suppressant system which will drown them
What more there is to get? What are some things humans really need and want, but we haven't invented it yet?
I mean sure we could invent flying cars and faster computers and ways to get more food and colonialize Mars, but I don't really think humanity deserves or needs any of those. It just keeps asking for more. Just like a child; what is the point of buying new and new toys to a child that never grows up and always wants more toys.
Even if I would invent something very important and big, I probably wouldn't publish any of the results. Maybe if I could get very rich, but just for fame? Not a chance. I think humanity has all they need atm.

>What more there is to get? What are some things humans really need and want, but we haven't invented it yet?
when humans want to survive we need to explore space. in the long run earth is a death trap. asteroids, a collapsing sun etc. we need to colonize other planets and we need huge spaceships/spacestations to find more planets to colonize.
As long as the imagination remains unfulfilled we must push foreward. If you think it's a matter of deserving something or not I think you're too caught up in contemporary social drama. If your argument is from guilt then sure we've made plenty of mistakes, but we'll never be able to rectify that unless we keep advancing.
We're living our lives stuffed in a tiny box defined by physical limitations while we yearn for freedom. It's not about "things" it's about possibilities and potentials. What humanity needs is complete freedom. That's "what there is to get".

Doesn't have to be big.
Someone pls explain how Recurrent Neural Networks work and how it is implemented. Just can't wrap my head around it

>give algorithm set of data
>give algorithm desired result of data
>algorithm attempts to brute force result, checks its answer, and propegates backwards to correct errors
>repeat until desired result is achieved
Thats a supervised neural net
Unsupervised is more like
>give net data
>net runs data through nodes
>regardless of correctness continues to loop and strengthen connections of nodes that produce simmilar answers
A supervised net is good for, for instance in a video game, to give a charater a starting point and a finish line, and find the optimal way between the two points.
An unsupervised net would be given the starting point, then figure out something you can do with the character.
If after the universe stops expanding it starts contracting again and eventually blows up from the pressure again in an infinite cycle, it means it has already happened an infinite amount of times and will happen again an infinite amount of times. that means every conceivable combination of energy, matter, events, etc, ie you and your entire life, has already happened an infinite amount of times, and will replay again an infinite amount of times.
Is that a scientifically accurate statement? How does time play into it? What is the effect on time once the universe starts contracting?
It's not scientifically accurate if you can't prove or disprove it.
>>8686190
nah but if determinism were real couldn't we figure it out and prevent something that was supposed to happen from happening? in effect disproving determinism
>>8686190
I see the oscillatory universe theory has basically been disproved. Too bad, was sort of comforting to think i'd see all my dead friends and family members again.

Does the theory of evolution only appear to contradict the second law of thermal dynamics because of an open system?
If so, how?
It's a law of THERMOdynamics. THERMO

It has to do with energy. DNA can become mutated all because of energy
>>8686296
Evolution is a fact. It has been observed; hence it does not violate the 2nd law of thermodynamics
