I'll answer your question anyway OP, Mozart's Requiem in d minor for C# and Python, Bill Evans's Time Remembered album (or other album) for Java, Prolog, XML, Powershell or any low level language
Techno or dubstep or whatever you want for Django, Javascript, CSS, HTML5 or any other remedial stuff.
Hope this helps!
I know a lot about music and a little about programming

If 36C is the human body temperature then why does 36C feel so fucking hot?

It's your core temperature. Extremities and peripheral tissues are cooler, and the former serves to radiate heat, despite having lower surface area.

lol m8
Ur silly so I'll help you out. Feel your skin, its warm, innit? Your body is constantly producing heat, like any machine. If youre 36c and the ambient temp is 36c, that heat has no where to go. Ur feeling fucken hot because you're storing all that extra heat.
I hope you learned something you silly wanker. This question made me laugh!

We had a question on b about the possibility of Luke and Leia birthing Rey to account for her extreme force sensitivity.
Since luke and leia both have the force gene from anakin, rey should be doubly strong.
People complained thoug because incest, and its dumb because its a galaxy far far away so why should they have human taboos.
But people said that luke and leia would not have had a child because incest deteriorates the human genome.
I asked that how do you know they are "human" and that their genomes might not deterorate from incesty.
Its the only that makes sense right?

According to classical genetic reproduction theory she would still only have 25% chance of having two alleles, 50% of being the same as Luke or Leia and 25% of being normalfag. Alleles can dominantly expressive in the phenotype, have shared expression (think the baby of cuckhold porn who is half black half white) or be suppressed by the other allele. In all cases she would have the same or less power than Luke or Leia, not more.

It doesn't matter if they're human. They're diploid sexually-reproducing organisms. Inbreeding is a thing in mice, fish, monkeys, etc.

>>7744754
Maybe midichlorians are all from the mom like mitochondria. Also, concentration of diseased mitochondria can increase or decrease in daughter cells based on which cell gets what part of the cytoplasm by chance, so maybe she got an even higher 'good midichlorian' count than Leia. Maybe kylo ren got unlucky and got diseased dark side midichlorians.

Pretty much this
Drugs are always on everyone's mind because

2) drugs are have a wide variety of structures to play with + there are multiple ways to produce it better/faster/cheaper. It's a fun competition
Explosives for 2 reasons
1) we've been drilled in the lab from day 1 that an explosion is something you never want to happen (now you get to make them)
2) explosions are fucking awesome

No, in fact the most common major to be accepted with is pure math, and physics is the portion of the MCAT most people have trouble with, youre honestly more set than bio majors, but you have to start studying today, 1 hour every day for like 9 months and youll be good, if you cram later youll fail.

I want to pursue research mathematics as a hobby, a supplement to a career (science, engineering, art), or even a career in and of itself. What particularly excites me about mathematics is how seemingly disparite formal concepts can be linked though a newly discovered theory or generalization.
In mathematics there is a lot to memorize if you intend on keeping up with the latest discoveries. Even if you are specializing in a particular branch, as most mathematicians do, the amount of theorems you must be able to recite and have available to you at any instant easily goes into the hundreds.
A lot of books exist on the various branches of modern mathematics but there are very few on best-practices for everyday working mathematicians. In the natural and social sciences, university laboratories dictate the pace and style of research. Also many guides exist for best-practices for conducting non-theoretical research. However for mathematics, approaching research-level work seems almost impossible without going the graduate school route at a decent school.
Where does someone begin who only knows fundamental definitions and a handful of theorems, with no specialization in mind yet? How do people who are tied up with other aspects of life get to the point where they are active in the mathematical community?

It is almost impossible to compete at a high level academically in mathematics as just a hobby. You would need to be a fucking genius or that one guy who lived with his mom and solved that millennium problem. Most people pursue an undergraduate degree in mathematics, then branch to a masters degree and then go to graduate school while doing a PhD. The academic path is never for the faint of heart who give up easily. Its going to be torture at times. But the more satisfying it is when you finally get it, when I finally clicks. However don't fool yourself: you will have to spend fulltime on this, and even after working hours your mind will be busy thinking about the problems. If you are hoping to compete at the edge of mathematical knowledge, you either dedicate your life to it or do not try it all.

There has been a fair bit of excitement recently over the efforts of a group of startups in the world of Fusion energy, such as tri alpha energy, Helion energy, and efforts from Lockheed Martin, to develop reactors on a time scale of perhaps a mere decade from now or less. Im fascinated by this, but still harbor doubts, given the long, frustrating history of fusion power generation over the last 60 years.
Will the extreme difficulty of sustained fusion once again humble mankind, or are we finally ready to tell the saudis to get fucked forever?

Oh, i forgot to mention general fusion, although i think the approach they are taking might be a dead end

>he thinks we won't need saudi oil even after fusion
You think we're gonna be driving fusion powered cars very soon?
Ships powered by on-board reactors? Aeroplanes?

I would hope a majority of cars are made to use electricity within 40 years, or that we can make fuel with genetically engineered plants or something.

Volume 1 or 2? If 2, just power through it, OP.
If 1, Spivak's calculus is much more readable.

Can you explain this plz for someone who doesnt know wtf this means? More specific - what is the Axiom of choice, I dont get it how it has anything to do with mathematics.

It's a really easy concept dude just read it more. Basically there is no set with a cardinality, k , such that aleph0<k<aleph1, this is abuse of notation though.

I've started learning C++ as my first programming language three months ago. I didn't have any programming experience before that, and until now it is still all kind of blurry.
My question is: how do you start thinking in programming language, so you can solve problems?
I could say that I kinda understand the overall look of how programming looks and works like, but I just can't start thinking in the way so I could solve problems. If someone else told me the solution, I would be like: "oooh, yeah that's totally easy!" But I can't seem to come up with solutions on my own yet.
I understand how if statements, loops, functions, arrays and structures work - this is what we learned in school so far.
How was your first experience with programming? How long did it take you to just "get" it?

Start of by solving trivial problems and move from there. Make a random name generator that just puts together names from a list of first and last names then move onto something slightly more difficult like making a minesweeper that works in your terminal by taking the coordinates of the place you picked. Its all practice, no matter how simple the problem may seem. You'll eventually see patterns and how to solve some primitive issues as they arrive.
