How the FUCK do you do integration by parts?
>>8519476
Give us an example so we can explain it to you
>>8519476
take U as the function which will reduce nicely such that V is an easy function to integrate on its own
>>8519479
Literally anything. What does the big sloopy thing mean? What does v, u, and d mean? I thought his was only single variable calculus

well you eventually will need glasses
>>8519484
I already need them to see far distances. But I know people who I never see wearing glasses, but then suddenly use them during poster contests.

Will math ever end or will there always be unsolved theories and problems.
Is the extent of math only go as far as the extent of physics?
If not, then what is math describing once it goes past where physics ends
Well science is about to reach a hard limit until they break free of the Masonic lie that is gravity(Big G/God/etc).
No field extends past the barriers we constructed for it.
I have a mountain of mathematics, physics; chemistry, computer science and security books to study, annotate and revise in six months.
Recently however I have noticed an endless sea of brain-fog twinned with a lack of motivation.
I'm trying hard to stay on track: trying to get enough sleep, trying to go for a morning and afternoon walk; trying to improve my diet and none of it is going very well.
So, my question is, how does /sci/ maintain their focus and motivation?

>>I've also been trying NoFap, is it a meme?
Yes. Masturbating before sleeping actually release your frustrations, spend energy and can help you have a better sleep.
It's mostly willpower and removing temptations. Study alone, compare problems with friends.

Thank you, anon. I did suspect NoFap was a bunch of shit.

What is good however is noPorn. Try fapping to your imagination, without a screen.
For sports, you should walk/bike to your university, that's a fairly good way to do minimum exercise.

How did your parents spark the flame when you were young?
What made you like maths, sciences, or even literature, maybe history?
I had to take a maths course in my first year. It was the hardest thing I ever sat through, and I scraped through with a C+.
Next year I changed my major to get more of it.
I hate what I'm currently studying
>>8519038
I used to build guitar pedals, oscillators, and all kinds of other noise makers. So it made sense to do something electrical, did Comp E, though, because memes.
Hey sci, I'm looking for some advice...
I'm struggling immensely with Quantum Mechanics (I took two semesters undergrad and am now finishing up a semester of graduate QM) and I need to understand this stuff. I just feel so stupid and way behind my peers. I want to get better but I think I'm flawed at the fundamentals. Any advice or tips to self study over the upcoming break?
TL;DR: I'm retarded when it comes to QM, how do I un-retard myself (is it possible)
>>8518985
Are you struggling with concepts or linear algebra?
>>8518985
Only the obvious one. Study. A lot.
He's going to make it to 2045, right guys?
I don't think I could take it if he just missed the boat ;_;
>>8518968
Kurzweil is an intelligent man and it would be saddening if he died.
With the way technology and medicine is currently going however, it is possible for him and many other individuals who can afford the care + healthy living to make into 2045+ and up.
But ultimately it comes down to chance if he dies from natural causes, an accident, or something else before 2045 roles around.
Better thing to hope for is for all us to make it into 2045 and a better future.
What's so special about 2045

How well does nuclear power miniaturize? Most nuclear reactors now (or maybe all of them) boil water to spin a turbine so it would definitely help if we could find a way to more directly harness that energy, and fusion would help even more. I figure a car could at some point be powered by nuclear energy since subs already are (though there are some problems with this) but is it realistic to think we could at some point use it to directly power things like cell phones?
>>8518835
You want a nuclear reaction going on beside your ear?
The nuke plant charging a grid that you plug your phone into to charge its battery works fine for now.
>>8518835
I used to have the exact pic you picked for your post printed out as a poster on my wall, only the font wasn't comic sans.
The only real issue with implementing it in small normal devices is what could go wrong. Imagine someone dropping their phone into the toilet and down the stairs and the next thing you know the city block becomes Chernobyl 2.0. I dunno though, I have. A bias against nuclear energy since it keeps destroying my shit in Simcity. (╯°□°)╯︵ ┻━┻
>>8518951
As long as we can find a way to properly shield it I can't see why not. At least radiation wise. The noise could be a problem though. I figure small devices are a long ways away if ever but powering a car with nuclear energy should be possible to some extent. I was reading about nuclear submarines recently and their reactors last the entire life of the sub itself, never needing to be refueled, which would be a godsend for cars too.
>>8518970
There's always going to be issues with what could possibly happen with energy sources. I mean right now there are phones that literally melt because of the battery. The small amount of nuclear material needed to power a phone shouldn't emit as much radiation as the amount used in a power plant I would imagine. If we could cure cancer that would eliminate one issue with spreading radiation.
Does uni, and final years of institutional education, get any better? I'm going into my 3rd year at uni for CS (Yea yea, I know, just shit post your "meme career" and get it over with) and I feel like I'm going nowhere in life. I going to start doing internships in the following summer but idk what to feel.
Also, does anyone else feel that this "rounded student" meme is complete bullshit? I have to take class I could give 2 shits about, but am required because reasons
>>8518777
The rounded student meme made sense in its time. Universities weren't utter shit. They didn't want maximum autists coming from their schools with zero knowledge of culture, history, literature, etc and just being math robots. They wanted a degree to indicate that beyond your major, you also had some understanding of the world at large and some context for your place in it.
Also the Internet didn't exist. So if you didn't force that knowledge on people, they could end up tremendously ignorant about those things in a way that is almost impossible now because knowledge of everything is just available to you.
>>8518791
Rounded student meme still makes some sense to me - it's important to be forced to at least dabble in some other things. Vital information can be found on wiki but for ex. I had to take econ, and now I have a somewhat decent basis of econ knowledge and an econ textbook around for reference as well,
>>8518777

My Biology Professor is adamant that we are. He claims that the genetic origin of cancer is completely false and that it is caused by problems in the mitochondria.
In fact he believes in this so much he almost started crying and called Cancer researchers jackasses and began to mock people that attend things like relay for life saying it was all hopeless and because the Cancer industry is quote "bullshit" and is too caught up in Dogma to realize the truth about the disease not being caused primarily by genetics.
Is there proof for his theory that it isnt genetically caused?
>>8518702
I think cancer is normal and a healthy part of life on earth. Without the odd mutation we wouldn't even be here.
>>8518732
But is it a consequence of issues within in the Nucleus or outside of it?
>>8518736
How is a mitochondrial issue theorised to result in unregulated growth?

Hey /sci/,
convince me how I can adopt children without feeling like someone who just got cucked. I need a way to justify that adopting kids isn't the same as getting cucked by someone.
>>8518617
There are two parts of you that you care about preserving: genes and intellect. Of course animals care about preserving genes. But for humans we also care about passing along our worldview, value system etc. Adopting allows you to preserve this (arguably more important) part of yourself. Imagine two options: you can have a random person have your genes, or have them approach life in a similar way to you. I'd definitely pick the latter.
>>8518617
if you're considering adopting you're of inferior quality to begin with
so if you adopt someone else's kids you are actually cucking them by taking their genetic progeny and infusing them with your shit-tier way of life (which was already shit to begin with, so taking care of their children doesn't make you a cuck)
Well, for those who aren't able to conceive naturally, whether due to being gay, transexual, infertile or just too old, adoption is the best way to raise children and have a family while helping change a life, there's nothing cuckworthy about it.
But yeah, if you and your partner both have functioning opposite-sex genitalia, you might as well just get a chastity belt and hold a breeding session and invite every negro that you see.
