Dumb people hate Math because they can't do math, & failing in math make them feels dumb (actually they are really dumb, it isn't just feeling)

Fucking hell, I thought Alec Guinness was based.

It's easy to say that they're dumb, but being realistic that's not always the case. Math requires work and determination and a lot of young people simply don't care, they don't study it because they think it is boring what lead them to not understand it what then end in them failing it what makes them really hate it.
The pic is also really dumb, math is full of creative ideas, some great mathematicians were clearly really creative, the guy in the pic probably never tried to understand math what lead him to have this stupid perception of the subject.
He may even not be dumb, maybe he could understand and like math if he really tried, but that was clearly not the case.

>there are also brainlets who really aren't capable of understanding it.

Norbert is quite good. The paper is 38 pages long... I'll read it tomorrow at work - but it seems legit.

I just finished reading it and while there were some parts I couldnt follow it looked actually really good.

He has a few papers on data structure lower bounds and a paper on his pet model of Boolean network functions published in a low-impact journal. He is not a reputable researcher on the topic, and the paper makes a bizarre claim that a lower bound method for monotone circuits extends easily to general boolean circuits. I don't, for example, see how Theorem 6 couldn't be applied to the majority function to extend the known Ω(n2) lower bound for monotone circuits to general circuits, contradicting the known O(log n) constructions for computing majority with general circuits.

About a year ago, there was a similar submission: https://arxiv.org/abs/1602.04781
which also claims P!=NP (in different words). If you look at the end of the paper, the author thanks Norbert Blum for reviewing (and indeed google confirms they are both professors at the University of Bonn). Not to say that Professor Blum's submission is invalid, but it certainly hurts credibility in my mind.

It's also worth noting that Blum's paper has some of the original criticisms I had of Hauptmann's, namely that it doesn't seem to connect to existing research on the topic, such as why this approach succeeded where others failed or how this approach relates to the massive amount of open questions that are closely tied to the P vs NP problem.

To be specific, the paper I linked claims that the Polynomial Hierarchy does not collapse all the way, but a well known result is that if P = NP then PH collapses entirely, therefore making any claims to the contrary is also making a claim against P vs NP.

(OP here again)

PS, please don't let this thread degenerate into a debate about IQ, heritable intelligence, or differences across populations.

1. IQ (g-score) is the single strongest statistical measure to come out of the social sciences, and correlates with academic and financial success. The various s-scores are not sufficient substitutes for the classical IQ / analytic reasoning test (YET).

2. Intelligence is determined mostly by genetics, and is heritable. Intelligence is more heritable than whether you are left-handed or right-handed.

3. Yes, average IQ distributions vary nation-to-nation, and race-to-race.

4. NO, INTELLIGENCE IS NOT THE DETERMINING FACTOR IN THE VALUE OF A HUMAN ENTITY. THE HUMAN ANIMAL AND HIS MIGHTY SPIRIT IS TOO VAST TO BE QUANTIFIED. INTELLIGENCE IS NOT THE MOST NOBLE TRAIT.

Please, and thank you. Love you all very much, hope you're having a wonderful day. Can't wait to read your posts.

It'll probably become practical within 50-100 years or so, excluding any social stigma, or political red tape, also:

How it communicates with itself many times over in a brief period of time

Define "aware".

If you actually cared about the answer, you would have at least done this.

I sort of meant it as another way of saying conscious.

Like, what makes us alive, as far as thought goes? Does that make any sense?

Hard to tell, upbringing is influenced heavily by societal reflection upon the individual, fat people will be treated differently, and thus their development will be different
Can't think of any experiment that could prove a direct link between being overweight and being stupid, but you can probably concoct some statistics about it nonetheless, given the large sample size you have in america.

Maybe it's the other way around, maybe being stupid makes you fat

Nah, at least in women's case it's true that fat reduces their intelligence. but if you'd googled your question you would've already found that out.

I have a theory that IQ has more to do with brain metabolism than anything else.

Smart people seem to be able to remain fit and healthy despite never doing any physical activity.

Actually total eclipses only happen every few years. Most eclipses will only be partial eclipses. This is actually because of a "lack" of exactness, if the moon's orbit was completely circular, and if it was a little closer to earth, and in the same orbital plane (It's actually titled by about 5 degrees) as the earth to the sun, we would have total eclipses every single month.

>>9102974
>Can someone explain why solar and lunar eclipses are so perfect?
They really aren't. They don't happen that often, and when they do, you are lucky if it goes total.

Also, the moon is slowly orbiting away from the earth which means that total eclipses will slowly become rarer over time.

>>9102974
>Isn't a bit of a coincidence that the moon is the exact distance between Earth and Sun to create such an effect and block the Sun completely?

Yes, it is. But it was not always that way, and it will not always be that way, which makes it all the more amazing. This guy knows:

Color constancy. During visual processing the brain attempts to control for differences in lighting, whether it be brightness or color, so you still perceive an object as its "actual" color (relative to your overall visual processing in general).

false, there is red in the pixels it is just much less intense than green or blue

This dude built himself a portable railgun. Not sure how reputable the source is.

http://newatlas.com/us-navy-electromagnetic-railgun-field-deomnstrations/50631/

Here is the US Navy's idea of a railgun. Their goal is to turn ships inside out so it much larger.

I don't think a portable railgun will ever be used outside of anti armor. Also, I really doubt it will ever replace conventional firearms. The AK-47 works too well to ever be replaced. It truly is the pinnacle of handheld kill.

I was going to build one years ago that fired nails with the heads cut off. Thought about building a condenser for liquid nitrogen, and having some means to optionally use a canister of it that lowers the temperature of the projectile. Never figured the means to actually do that without rendering the rest of it unusable from a human standpoint. That gets into all kinds of complexity as far as controlling heat transfer, and at that point I'm deluding myself as far as manufacturing capability / skill. It's not like I have a lathe or mill kicking around.

conceivably yea they could just become the dominant form of firearm at all levels but it would take some extremely large leaps relative to where we are now in engineering to solve some of the problems anons already mentioned primarily heat disposal, energy source, shielding. Additionally we would need to design a projectile that can reliably quash itself when hitting the target because putting a small hole through something is generally fairly useless unless the KE of the projectile is so great that what energy it does transfer before over penetrating is already lethal

Intelligence is relative. Attempts to derive a meaningful absolute intelligence have generally been net failures when applied in a non-pathological setting.

Where does American popular culture meme even arise from?

Asians are literally intellectual garbage.

They were abandoned in the 1960s because "dats raycis" when it became clear that blacks abos and SE asians/poos were subhuman tier.

Why are we ignoring the 2000 years of recent history when Europeans invented 95% of everything?

Economists are certainly better than civil and mechanical engineers.

Yes

Engineers are brainlets who couldn't into physics or mathematics. Economists are critical thinkers who use mathematics as a tool

Because evolution is a fraud

because evolution is just a theory (a guess)
