Are we all fucked? This NASA-sponsored study depresses me. It basically says that we have a few more decades left. Any thoughts?

Why you think its natural phenomenon ?

probably not

its probably a planet during orbital decay shedding its atmosphere or some weird formation of comets
I'm wondering what /sci/ thinks about cognitive sciences. Now, it is obvious that they are different from both the natural sciences and social sciences, but what is the nature of the information they create/produce? Are they/can they be "objective" (please don't derail the thread with radical subjectivism, accept naive realism for thread's sake) like physics and be produce abstract, logical knowledge like maths, or can they not?
Of course, some of these sciences include fields based on "historical knowledge", like historic linguistics or...

The brain follows these rules:
1.) Particular functions are handled by particulars parts of the brain
2.) The brain stores information and related information [longterm-shortterm; abstract-literal]
3.) The brain is reactive to threats and attractions [fight-flight; attraction-attachment]
And that's basically it. The complex part is finding out:
1.) How it does it
2.) How it came to be that way
3.) The detains of storage and relationship model building

The result of an electrician with autism.
ITT I will try to solve (and in fact solve) all the Millennium Prize Problems one by one. I will do so by a new proof technique that has been proved to be quite powerful. It combined homothopy theory with algebraic geometry. Having said that, the proof technique itself is elementary though. So, let's go ahead.
1. [math] \displaystyle P=NP [/math]
By definition, polynomila algorithms admit decomposition in chains of smaller polynomial algorithms. Consequently, polynomial time algorithms do not solve problems where blocks, whoose order is the same as the underlying problem, require simultaneous resolution. Thus, in fact [math] \displaystyle P \neq NP [/math]
2. Hodge conjecture
Assuming that if a compact Kähler mainfold is complex-analytically rigid, the area-minimizing subvarieties approach complex analytic subvarieties. The set of singularities of an area-minimizng flux is zero in measure. The rest it left to the reader as an easy routine excersize.
3. Riemann hypothesis
This is a simple experimental fact. [math] \displaystyle 10^{13} [/math] roots of the Riemann hypothesis have been already tested and it suffices for all practical applications. In fact, one state a suitable statistical hypothesis and check it on the sample of, say, [math] \displaystyle 10^5 [/math] roots.
4. Yang–Mills existence and mass gap
Well, discrete infinite bosonic energy-mass spectrum of gauge bosons under Gelfand nuclear triples admits non-perturbative quantization of Yang-Mills fields whence the gauge-invariant quantum spectrum is bounded below. A particular consequence is the existence of the mass gap.
5. Navier–Stokes existence and smoothness
(To be continued)

I haven't worked this one in such detail, but observing that
[math] \displaystyle \| L (u, v) \| ^ 2 = \sum_{n \ge 25} u ^ 2_ {2n} v ^ 2_ {2n +1} / n ^ 2 \le C\|(u_n/\sqrt n)\|_4^2 \|(v_n/\sqrt n)\|_4^2 \le C\|(u_n/\sqrt n)\|_2^2 \|(v_n/\sqrt n)\|_2^2 = C \left (\sum u ^ 2_ {n} / n \right) \left (\sum v ^ 2_ {n} / n \right) [/math]
one can easily find at leat one closed-form solution applying the bubble integral. In the equation, [math] \displaystyle L [/math] is a bilinear operator.

The statement of the title, is, in fact, meaningless, because it tacitly assumes that we can add-up "infinitely" many numbers, and good old Zenon already told us that this is absurd.
The true statement is that the sequence, a(n), defined by the recurrence
a(n)=a(n-1)+9/10n a(0)=0 ,
has the finitistic property that there exists an algorithm that inputs a (symbolic!) positive rational number ε and outputs a (symbolic!) positive integer N=N(ε) such that
|a(n)-1|<ε for (symbolic!) n>N .
Note that nowhere did I use the quantifier...

the fact that you can walk from your chair to the door is proof that you CAN evaluate the sum of an infinite series (halfway there, and half again, and again, etc.)

Will the Riemanm Hypthothesis ever be solved? Like really, it's been around 157 years already and a million dollar bounty on it has been active for 16 years.
Maybe, maybe not. Certainly not by me.
>>8116679
That doesn't look that hard.
Just find the roots for the real part, and then find the roots for the imaginary part, and then you just have to show that they're the same when the real value is [math]\frac{1}{2}[/math] in the critical strip.

Why do depressed dumb people not exist? Is a high IQ a prerequisite to depression?
>Why do depressed dumb people not exist?
bs
>Is a high IQ a prerequisite to depression?
sort of true
>>8116586
IQ does not equal intellect. Intelligence is the source of depression, which is a rationalized method of self-hatred that avoids outward action onto innocent people that surround the depressed. The more intelligent you are, the more probable it is that you will not unleash anger due to your internal self-loathing on others, thus not generating the catharsis which may alleviate the depression for a time.
>>8116586
Depressed, dumb people are very common. Stupid people make bad life-decisions that eventually cause them setbacks. When this happens, they get depressed and/or become pathetic losers. This category is highly represented in depressive people.
Is it possible to learn a semesters worth of Calc 2 in one week?

focus on ur derivatives and u-substitutions
also maybe look into partial derivatives

Literally just did this, working on Calc 3 currently. It was hard as fuck and I had to go back and reprove a lot of it to myself but in the end I have a reasonable handle on it all.
It's possible, just hard.

How effective are vitamin supplements really? Can they even be harmful?
I am no medical doctor but have been involved in sports for a while. Vitamin supplements are rarely needed by the average person with a balanced diet. They're most effective when a person cannot get all that he needs and thus starts experiencing negative symptoms (hair fall, oily skin, anxiety and all kinds of stuff depending on the vitamin missing). On the other hand, supplementing with them when not needed may lead to a condition called hypervitaminosis which is really bad. What happens is that some vitamins are fat-soluble (they dissolve only in fat) and thus remain...

They are helpful if your diet is poor. Otherwise it's probably better to get your vitamins from whole minimally processed foods unless you have a specific condition where megadosing is indicated like abetalipoproteinemia.
>Can they even be harmful?
Yes, supplementary vitamin C for example can have a pro-oxidant effect and impair some of the adaptations to exercise.
>How effective are vitamin supplements really?
Your body will not absorb all of the vitamins/nnutrients/whateveryou'retaking that are in the supplement.
Your body will absorb almost all of whatever from your food.
Supplements with a shit diet are better than a supplement-less shit diet though.
>Can they even be harmful?
Yes, if you over does.
Which is usually pretty hard to do.
Be careful though, depending on what you're overdosing on things can get nasty.

It's due to conflicting worldviews. What's weird is that people didn't have a problem with it when it pertained to animals only, but once humans entered the mix, then people got a little "concerned."
