Hi /sci/
Is there any possibility in the near future that we will be able to create artificial helium or non-flammable hydrogen?
Thanks,
Blump
No and no.
But hydrogen is not as dangerous as you think it is.
No. Even if we did, airships are not coming back: http://blogs.scientificamerican.com/guest-blog/helium-hokum-why-airships-will-never-be-part-of-our-transportation-infrastructure/
What are the best books on Markov Chains
>>7676664
Depends on if you're interested in statistics/math or in artificial intelligence.
>>7676675
In the math side of things
>>7676682
No idea. I'm a pure mathfag and I would recommend none of the stuff I've done from the math side of things (stochastic processes). It's all incredibly boring compared to the AI stuff, in my opinion.
Good luck OP.
What's the difference between taking Adderall to help your studies and smoking crystal meth? Why one is completely okay and respectable but another makes me a weirdo?
Because one is productive for society and the other is destructive. Some traditionalist mores can be hard to understand, but this one? Gimme a break.
>>7676556
How is one "destructive" when it's literally the same substance?
>>7676561
Because one is to get you high. When has someone high on crystal meth contributed to society?
It's like how painkillers can be abused. In their time-released pill form, they help people deal with pain. If you crush it up, and snort it, then you just are trying to get high.
So how did depression survive evolution? It's a fairly negative trait to have, it makes people highly unproductive and prone to suicide, so how did it survive until today and why is it still around?
>>7676430
>makes people highly unproductive
ok, but 'productivity' and 'ability/opportunity to procreate' aren't the same.
>makes people [highly] prone to suicide
no, most 'depressed' people don't kill themselves, only a small fraction do, still stands even if you take out the highly part
How did cancer survive evolution?
The brain is complicated and the emotional building blocks that make up depression all have evolutionary benefits until they go out of control.
Or if you're one of those horrible evolutionary psychology type people that can't stand complexity and so have to invent simplistic narratives for themselves, how about I just say that a biological gambit where 90% of the time you improve your life and 10% you make it much much much much much worse is a net evolutionary benefit.
>>7676430
Assuming depression is indeed inherited, it likely survived the same way many genetic disorders do, it is either carried as a recessive allele (so will only show if two people with this allele mate) or it is carried as a sex linked disorder on the x chromosome. If I were to guess I would say it is the latter as men seem to suffer from depression more than women.
So basically Einstein's theory of relativity is just saying that time and space have a bond, right?
Just checking
>>7676175
The theory essentially says, Space-time tells matter how to move, and matter tells space-time how to curve
>>7676182
So what is space time? Do you mean the way matter causes space to bend around it?
Define time.
Define space.
Exactly. Case-closed.
Could the Laws of Physics be disproven?
yes and no
>inb4 memedrive
>>7676027
Every law in physics has been disproven. Just not by much under normal conditions.
Now stop reading popsci and learn actual physics if you're so interested in it.
what are your thoughts on global warming is it caused by humans? is it even happening? or does it belong in the tales box together with the boogey man and santa claus?

>>7675862
I believe it, not by observation but by probability
Probably. I'm hopeful that we'll find a solution before significant damage is done. It's not even that tough to do. Albedo modification isn't that expensive, and although may have side effects, is better than nothing. If not albedo modification, we could use sulfate aerosols. We have many ways we can "buy time" to wean ourselves off of fossil fuels, which will naturally occur as prices rise.
>>7675901
It's probably the case but I'm with this anon. Any fans of carbon sequestration in here?
How do we read all of those textbook PDFs that we all pirate? Do you use a monitor pivoted vertically? Do you import it to an e-reader/tablet? I'm curious to what everyone uses since we seem to link PDF files and recommend all of these textbooks on a daily basis.
>>7675702
I would use an ipad if I had one, especially for journal articles. Otherwise I just view it in default mode on my chromebook

>>7675702
I double click it, and then begin reading.
>>7675702
you are autistic as fuck
just read the god damn thing you fucking piece of shit
Should I study pure Maths or Computer Science at University?
I enjoy Maths more but would I earn more money in Computer Science?
>>7674942
Eh it You go for pure math you can work of the nsa or some government agency.
I think it's still easier to get highered as a cs guy tho
>>7674942
Why not both?
Graduate in maths but learn programming in and out by your own
are there differences between the races, e.g. in IQ and bone structure/density?
Does race exist?
yep
>>7674733
I got told to come here because I'd get recked by /sci/
pls wreck desu sempai
I didn't really understand fractals, but then I did shrooms and now I'm the iron chef and crunching fractals.
Why aren't more math professors recommending this?
Also hexagram on saturn because shrooms
>>7674242
What special insight do you think you gained?
You're not any more knowledgable than you were before. You're deluded.
>>7674250
Well now I can do all the questions in the textbook as if it's second nature without having to refer to my notes.
Hello Sci,
I just got offered a job at IBM! Electrical Engineering major from state school in New England. Semiconductor test/characterization/22nm mumbo jumbo. 75k starting +5k sign bonus. Has anyone else heard back yet?
Lets hear what you boys and girls are up to.
fuck off
>>7673892
>75k starting +5k sign bonus
sounds a bit rich for that type of work. more like 45k-60k
>>7673899
No, it really doesn't.
collage student, wants to become a scientist, linked this: mathematicsofevolution.com/ChaptersMath/Chapter_150__Probability_of_Evolution__.html and asked why we haven't evolved night vision when someone offered an evolutionary explanation for why we are scared of the dark.
I replied with this youtube.com/watch?v=IPyKaH09lpc
Are we both close-minded little gits?
>all it means is that we perceive the present through a different worldview of the past
At which point the scientist, were he not a hypocrite, should be inclined towards the view which has more experimental evidence to support it. Evolution isn't something you can deny, you can literally see it happen in nature and in the lab at scales both microscopic and macroscopic.
Fuck, I could say I perceive the past as containing me winning the Nobel prize and that doesn't mean it's just as valid as any other interpretation.
Creatonists...

Creation is full of contradictions which no intelligible person can simply ignore and continue believing. Also what the other anon said; evolution isn't something deniable because it's being observed. Evolution is the outcome of mutation + natural selection and we do observe both of them.
>>7673680
evolution is a phenomenon of belief which, in the later cases such as macroevolution and ultimately speciation, is believed by many scientists. The issue that is being called into question is the following: why is it that these so-called scientists purportedly belief in such a phenomena? if these textbooks and opinions are to be maximally believed, then this must indicate that evolution is the case and is a fact. however, the case many not be so, exactly. one problem with the opinion is the EVIDENCE... there are usually...

Anyone else /prodigy/ here? I was taking college CALCULUS in HIGH SCHOOL (they call it "AB" Calculus I think).
But seriously though, tell us your stories all. What classes did you take in HS, did you graduate early, what shit did you test out of in uni, how many dumbfags did you leave in the dust
dropped out of high school to smoke hash. grad school for pure math these days.
Mexican descent here. Born and raised in America. I currently go to a community college and I am taking Differential Equations. I consider myself a prodigy since I'm not a gang member and don't have any kids.
I made a CLOCK by following the instructions I found online when I was only in HIGH SCHOOL. Epic level stuff right there.
/sci/ please help me collect some data. i hypothesize that most people in this thread are like myself; INTJ(-A) on the Myers-Briggs scale. i just want to test this with a good sample.
would be interesting if i were proven to be way off.

Also Myers-Briggs is some speculative bullshit, I don't think anyone takes it seriously. It's kind of fun though.
