Why can't the narrow-minded spergs of /sci/ accept that asteroid mining is the future?

Earth minerals are running out, space launch costs are coming down, it's not even a possibility, it's a fucking certainty.

>up to 2 kg from an asteroid to Earth, will cost about US$1 billion
Note that this is raw material which could contain no valuables at all
Keep getting into arguments about chemtrails.
Really, his is starting to piss me off. My explicitly stated standpoint is that I don't give a fuck. I have no means to test or verify, I don't know shit about jet fuel or upper atmosphere physics, and even if it were happening and I had means to be aware of this, I COULDN'T DO SHIT ABOUT IT. So what the fuck? Leave me the hell alone for fuck's sake!!
Aluminum is expensive and I don't know by what means you could disperse it in a way that does a goddamn thing to anyone. Likewise, barium poisoning is easy to verify throughout a given population. Strontium is in you anyway. That leaves yet unknown esoteric compounds being used for weather control, geo-engineering, to control selected populations (issue remains dispersal mechanism and dose control), or as a laughably pathetic counter-measure against climate change.
No. Relative to my memories, I've yet to see strange clouds or trails. Historically I've been apt to entertain and evaluate ideas that weren't worth the mental effort, but this shit is getting ridiculous. I can't stand people WHO FUCKING SCREAM AT YOU WHEN YOU DON'T SUCK UP THEIR WANTING RHETORIC.
FUCK
OFF.
But that alone isn't evidence, nor a sufficient framework for reasoning. So tell me /sci/, what do you think about chemtrails? And keep your own equally garbage "lul cunspiracy thorist r DUM!!" shit out of it. This is for real science, not your fuckhead circlejerk horseshit.

You're a moron. Clearly my first paragraph was whining, second was tame conjecture, third was venting, and fourth was tied to the actual first paragraph as a query.

no it's not
it's one of the cheaper metals we have
This is bothering me.

Any promising developments in tissue engineering? When can I expect to replace my organs? Also why isn't this the biggest thing right now? Stellerators are cool and all but pointless when you're dead.

Are there any arguments against determinism?
Even if there is a certain randomness in quantum physics I cant get how people believe in free will.
>>7721982
Because it would infer that if consciousness is universally derived, then it is universally manipulating.
e.i. the universe is consciously participating in itself. Yet, that is why we have god, because... spooky ramifications.
>>7721982
Look up Immanuel Kant and categories. In short: free will, causality, laws of physics, etc are categories through which you perceive the world. You can never achieve objective knowledge of the real world, but only subjective knowledge of the world you perceive. Therefore everything you experience is real for you, and that's the farthest you can go, so if you experience your will as free, your will is free for you.
>>7721998
Yet, subjective knowledge is not objective knowledge by discretion of the synthesis.

out of curiosity, how many of you went to/are currently going to graduate school?
how many of you are going for a phd? how is it?
I'm in grad school for math right now. I will be going for a ph.d after I get my m.s. here. it is awful, soul crushing work. you have to need a ph.d, like you cannot live knowing you aren't working towards one. because it DOES suck. the stress of keeping up with a class only to lose it all on a comprehensive final is REAL. if you arent willing to do whatever it takes, if you dont have the mindset of 'get a ph.d in math or die trying' then you should do something else.

This is an issue that has been bothering me for some time. For those who are unfamiliar, an O'neill cylinder is a space habitat in the middle of space, with an atmosphere filled interior where people live, and is rotated so that the centrifugal force approximates gravity on the inner surface. Mirrors reflect sunlight through large windows into the habitat, and day and night are simulated by adjusting the mirror's angle.
My problem is that the mirrors are also rotated with the same rpm as the cylinder itself, so it will experience a much higher G-force at the edges, up to 10g or more, so obviously your everyday mirror isn't going to hold up under the strain, especially considering just how large this has to be (at least around 10km). Why does no one ever bring up this seemingly obvious problem? Even if you can find a sufficiently strong mirror material, how are you going to adjust the mirrors without the hinges holding the mirror (and presumed by everyone to be the mechanism doing the adjusting) from breaking apart due to the massive force on it?
Also a side observation, has it ever bothered any of you guys familiar with the O'neill cylinder how everyone only knows this from Gundam? Many of my friends, after watching Interstellar, simply referred to the O'neill cylinder featured at the end as "Gundams".
>>7720943
Why the need for the mirror anyway? If we are advanced enough to build massive structures in space I would hope that our led technology has reached a point where we can accurately simulate sunlight.
Also material science is booming right now so I'd imagine the material for said mirror isn't too far off.
>>7720943
>how are you going to adjust the mirrors without the hinges holding the mirror (and presumed by everyone to be the mechanism doing the adjusting) from breaking apart due to the massive force on it?
....I think the best way to design such a mirror is to construct said mirror from an ultrastrong and ultralightweight alloy. And it would be concentric (and probably slightly concaved, albeit shallow).
Just my thoughts
>>7720985
>I would hope that our led technology has reached a point where we can accurately simulate sunlight.
Because we want to use a nuclear reactor expending rare and costly fuel replicating a task that could be accomplished by a shiny piece of metal or mylar, amirite?
What does /sci/ think of broscience?
Sometimes useful but not the reasons they think. Mostly wrong
>>7720834
So calories in and calories out is all I need.
nutrition and diet as some of the most specious topics in science.
I'd say there's only one solid piece of evidence for diet, a fat based one (low CHO low protein) in the case that you are suffering from Diabetes type II.
Otherwise, it appears as though ANY components of your diet (even to a significant extent) your caloric and glycemic intake don't affect your body transformation.
Exercise is amazing for the body, considering broscience driven by improving the capacity for execise maybe this cult of gains is the best way to go about changing your diet - the effect on your ability.

I wonder if there is a /sci/ approved way of learning? In about two months I'm going to write my exams at university and have to learn a book/script with around 300 pages for each course.
I'm not sure about taking smart drugs such as aderall, etc.
>>7720525
Get the course schedule with which chapters are covered, get schedule of homework, then sit down, grab a cup of tea or coffee and get working. Treat your studies as if it's a full time job, you will do better if you're serious and an adult about it.
>>7720525
From what I can tell the /sci/ way of learning is to curse bitterly that which you don't understand, call it a "meme", and then sit there and realize that you're not actually superior because you flunked your entire semester because you were shitposting on /sci/.
>>7720593

You have a blue die with 6 sides and a red die with 4 sides.
Suppose you randomly roll a die and roll a 2. What is the probability that you chose the blue die?

I think the number "TEN" should have its OWN numeral as I always wondered, since we're so used to counting in COMPLETE UNITS of TEN, why are there 2 numerals that represent the last number in each unit? Why have we started counting with a 1 in front of the TEN space? I think it should be like this.
1,2,3,4,5,6,7,8,9,X
and now that we are moving on from TEN it's...
11 12 13 14 15 16 17 18 19 1X
Ah, you thought 2x? well again, because we have 10 SPECIFIC numerals instead of only 9 and confusingly using 2 numerals to represent TEN, we don't say "20" we say 1X. so 1X is the same value still, but instead of an extra 1 added to the first number, we complete the numbers 11-20 with a 1X.
The reason I like it this way is it gets rid of the zero. It's so redundant. 0 itself has no value! It doesn't actually exist! It's nothing! So when we use zero we really just mean TEN in every case, even with 20, it's ONE PLUS TEN. So 1X ! Getting rid of the zero makes this much easier as you have a complete set of 10 individual numbers instead of only 9 and THEN repeating numbers before we even completed a unit of TEN!
Ok so let's do math
75
+75
----------
14X
so instead of carrying a one, which is a bit confusing to do I don't know why we do that stuff, it sucks, but we now can just drop down the value for this specific problem. So 150 is now written as "14X". As you can see, all we did is drop down the normal values. 5+5=X and then 7+7=14. As 14X means FOURTEEN and aTEN (not fourteen PLUS ten, fourteen AND ten) we can write it as 14X instead of 150
This speeds up the process of doing math and is much less time consuming (in my opinion)
Go ahead, try it.

What's your answer?

lmao
so 11 = 10 now?
11 is 11. We don't use a 0.
what are /sci/'s thoughts on this guy?
i think khan academy is a pretty cool guy. eh teaches math to children and doesn't afraid of anything.
good vids better than cc professor
Sites like khan academy and MOOCs like EDX make me still somewhat believe in the future.
