why is the ISS being decommissioned in the 2020s?
and why does the proposed OPSEK look like utter shit?
>>8036458
what's shit about it?
>>8036444
Nice trips. Cause it's getting too old. Could break down and kill people. Remember MIR? MIR was always breaking down.
Sup /sci/.
Medfag here. I want to do research, and I've become more and more interested in neuroscience. I'm interested in things like "does the brain use more glucose when concentrating" (it probably doesn't), how memories are formed, and the interaction between neuroscience and psychology. I'm also interested in computational methods.
What specific neuroscience field seems fitting to go into?
Oh dear, I also want to become a neurologist to do research. That said I was considering neuropsychology, but I'd be equally happy without specializing. Also, the brain pretty much uses static levels of glucose, about 21% of the body's metabolic reactions can be attributed to the brain, no matter how hard you may be thinking.

why do the electrons surrounding an atomic nucleus take on discrete energy levels?
>>8036320
why would the electrons surrounding an atomic nucleus take on continuous energy levels?
>>8036320
Cause they're in a potential. Check out harmonic potential solutions.
it's from the relation between the wavelength and the energy of a particle.
electron -> standing wave around the nucleus

Would HS be better if there were PHDs teaching there?
School of Anime

Undergrads are generally overqualified for that, so not. Alumni segregation by capabilities and skills would make HS better.
My old high school had about a 5:6 PhD to pleb ratio in the sciences. It was called "St Paul's School" and was in richmond i think.
It was kinda weird - what kind of a human is going to spend several years completing a PhD and then spend his vast knowledge tutoring teenage retards?
But it was nice to be able to chat to these experts regularly, and I miss that kind of frequent contact now I'm at uni.
ITT I will try to summon Emma-Stone-fag. We recently had a discussion, allegedly with you, on computable/constructive spectral theorem.
Namely, if [math]A[/math] is an [math]n \times n[/math] complex-valued matrix, then there NEEDS TO EXIST an approximate spectral decomposition that is effectively computable/constructive. This means that there need to exist approximate eigenvalues [math]\alpha_1, \ldots, \alpha_n[/math], approximate eigenvectors [math]v_1, \ldots, v_n[/math] such that [math] \| A v_i - \alpha_i v_i \| \leq \varepsilon [/math], approximate projections [math]P_1, \ldots, P_n[/math] such that [math] \| A - \sum_{i=1}^{n} \alpha_i P_i \| \leq \varepsilon [/math] projecting onto invariant subspaces whose dimension and bases can be effectively computed and the whole space decomposes into a direct sum of those.
You recommended to contact some bigshot in this field. Apparently, they don't even notice messages among shittones of spam. If you have contacts to them by any chance, please ask. This problem has a number of serious consequences.
>>8036202
nigga no need for no big shot
1/fix an epsilon
2/start with the classical algorithm to find the biggest eigenvalue and an associated eigenvector (power method or a variation of the power method)
once you have that, you see that you only need to scale the eigenvector v1 you found so that ||Av1 - a1 v1||<epsilon.
Now you can just repeat by changing the matrix A into a matrix restricted to a subspace that excludes v1.
Eventually you get all the eigenvalues you want, the associated eigenvectors and the transformation matrix.
This gives priority to the highest eigenvalues (in magnitude). IMO this makes sense since they contain most of the information. But feel free to modify this to match your expectations
Is this OK or did I misunderstand something?
>>8036352
>to find the biggest eigenvalue
You immediately pooped your pants here.
>>8036202
Seems hard to believe. A can be any matrix? Not just hermetian or normal? Are the v_i supposed to be nearly orthogonal?
Seems like you are saying all matrices are nearly diagonalizable.
Does anything actually exist beyond physicality?
No.
everything "burns" if you "heat" it hot enough converting every physicality into energy, so the real question is:
Does anything actually exist beyond energy?
>>8036096
is energy not the movement of physical pieces?

So:
A.) Psychiatrists are bad at math?
C.) More people are becoming ill [odd, I thought medicine halted epidemics]?
D.) More illnesses are being discovered
E.) Expanding criteria is either false or had until recently underdiagnosed billions
F.) The entire thing is bunk
G.) ???

This makes me very depressed.
More diseases are being discovered and the scope of prior diseases are being redefined. As you so very clearly illustrate yourself, mental health has very ignorant connotations associated with it and it's important to point out that not everyone who has some mental health related issue is a stark raving lunatic who has to be locked up in an asylum for the rest of their life.
You wouldn't find it odd for a doctor to state that >=50% of humans will experience at least a cold in their lifetime, and will at point during this benefit from a cough drop or aspirin. Why are you so horribly offended at the idea that the majority of us will benefit from a session of counseling or a short round of chemical inhibitors when the mind is going through an unduly high amount of stress?

So I just spent 2 hours research this for no reason?

the environment was never tested for EMF or radio or microwaves
the test was not valid

I don't understand you
Are you being dumb on purpose?
I am a freshman at my university and I have programming One among other classes. My math skills suck ass and so I am doing college algebra (which is too fucking easy but I'm getting there), but I think I failed my first test since high school today.
The test was mainly on arrays and 2D arrays in Java. From a guy who has been doing really well in the class so far (96/100 total grade), I feel like absolute shit for what I believe is bombing this exam (probably scored a D or a C).
Is there any hope for me, /sci/? Can I still become a programmer? Did you awesome coders ever have a hard time learning something in programming?
>>8035766
But I'm not only majoring in CS, anon. I was even thinking of switching over to CE, since my brother and father are computer engineers.
My granfather is an electrical engineer and my half uncle works in IT.

Yeah, no.
What does /sci/ think of abaci?
>>8035720
We use calculators here caveman.
>>8035853
You can do calculations on an abacus faster than you can type them into a calculator.
>>8035854
Is that why they use abacuses everywhere?
Is there any reputable interpretation of quantum physics that's deterministic, or am I just being dogmatic when I don't buy randomness
