Well I mean, its not small...?

I don't know something related with scape or black hole, long distance shit , anything.
They don't call planes and jets "big metal flying structure"
I see a lot of talk about intelligence, but what about creativity? Is there a concept of creativity testing in psychology/sociology? Is there a such thing as g-loaded creativity? Can it even be measured? Are there aspects of creativity that aren't subsets of intelligence?
Take your pedophile comics back to >>>/a/.
"intelligence" isn't really a scientific term, and it isn't used by psychologists on a regular basis. There are types of intelligence, when you are trying to take some predefined measurable traits and quantify them, but even those only give you a rough clue.
The general approach to modern psychology is not to try to quantify things. The brain is a very complicated organ, and the most accurate predictions come when we look at it as an entire system that exists under different distinct conditions.
From that point of view, it's less constructive...

The ICD 10 literally uses IQ as diagnostic criterion.

How does it feel to know that any crazy advanced tech like FTL, free energy, etc., if ever invented, would get legally barred from being disclosed or patented?

>...is a body of United States federal law designed to prevent disclosure of new inventions and technologies that, in the opinion of selected federal agencies, present a possible threat to the national security of the United States

>yfw P=NP
>yfw we already have working fusion power
>>8167555
That's the US. It's highly unlikely that Americans develop that kind of tech in the first place, so we're fine.
>>8167555
That's easy, just release it over the dark net, before telling anyone else.
So I recently read this article that talks about how scientists have discovered that the nucleus of some elements are pear shaped instead of being symmetrical. The article asserts that the reason for the pear shape is because the nucleus points toward a direction in spacetime meaning time is linear and thus time traveling to the past is impossible.
My question is since the nucleus is pointing in a certain direction, does that mean time has a directional component? Like if we traveled far and fast enough in the direction the nucleus is pointing would approach the future...

spoiler: the "article" is bullshit
>>8167500
this.
It's bullshit in which regard? The shape of the nucleus or the impossibility of time travel?

You just highlighted all that is wrong with the modern educational system. Kids who are taught nothing but theory and have no idea of what is going on on the workshop floor. This is why employers always demand experience. If you can't sort out a two-stroke engine how will you be able to design improvements? You really think that your Otto cycle diagrams are the be all-end all of engines?
>>8167456
>can't even fix a lawnmower engine
I thought engineers were supposed to be smart?
Why is pop science so annoying? I watched the minute physics big bang video, and not only did he oversimplify the history of cosmology, he acted like the "big bounce" and infinite universe theories were somehow unchallenged and settled science. And of course, he's made several videos with meme science nigger.
>>8167433
It's like homeopathy : A very small amount of science heavily sugarcoated in nice effects and good video editing. It's entertainement for plebs.
>>8167433
There is a video blocker add-on for Firefox and I suggest you start using it.
I have over 80 channels and dozen keywords blocked.
it makes youtube almost 99% clear of this type of content.
>>8167433
The videos are short and full of half-facts to please the greatest pleb audience possible. Lots of ad views = $$$
If it were not for the $$$ these channels would not be making videos. That proves that their content is intrinsically worthless.
What do you think about Biocentric universe / theory of biocentrism ?
>>8167383
Wow! I didn't know the universe looked like that!
>>8167383
It's not a theory, just a poorly formed idea.
The large scale structures of the universe do not have any functions that neurons do. The structures also lack connection to other specialized cells
or does it
What are the odds of getting specific dubs? Because I keep getting 7's and it's starting to fuck up my mind.
>>8167353
1/100
>>8167356
not quite.
probability of singles = 9/10
probability of dubs = 9/100
probability of trips = 9/1000 etc.
in the dubs category, the chances are spread between 10 possibilities (one for each digit).
So the chance of obtaining the string "X77" where X is not 7 is 9/1000.
>>8167356

thanks, fuck this shit, it's out of control, I know I'm suffering from confirmation bias but I just keep getting them, and they're always at the bottom of a refreshed thread. It's been happening for weeks. I just got them twice in a row as well.

if we camed from monkies, than y r their still monkies?

Cuz monkis camed from unicorns.

Wait. I'll explain your question with an infographic. Don't move! ;^)
My friend is a chemist and says astronomy is almost useless. I want to prove him wrong. What practical application dis studying phenomena too far for humans to ever reach serve besides helping to develop other technologies that can be used elsewhere?

it has had no impact at all.

so ive been reading up on klinefelters syndrome but i always see the term "frontal baldness absent" and i have no clue what it means. ik what male pattern baldness is ik what a receding hairline is but whenever i try to research shat this is i get confused. does it mean ur balding or that ur not balding because of lack of dht production?
>>8167118
It means you're not balding towards your hairline.
>>8167140
so for example mine would be balding towards me meaning i wouldnt have this
>>8167145
meant that as a qurstion sorry. im really worried i have this even tho i grow chest hair and a beard pretty well and my testicles arent really small. might just be anciety tho
What is the shortest way to connect all the cities? For example, Paris, Dieppe, Brussels and Zurich could all be connected with just 6. Similar to travelling salesman, but not identical. Sorry if there's a name for this and it's easily solvable.
My best so far is 108.
>>8167079
>just 6
if you use 6 lines to connect 4 nodes, you have no more possible combinations of nodes left to connect.
how is this a problem? its fucking trivial, there is no minimization here and a 10 year old could derive the generic formula for the correct answer
>>8167102
I was just referring to those four cities as an example. See picture for acceptable solution.
>>8167112
This would be quicker if it was classic travelling salesman, my point is that the problem isn't.
Hi /sci/. I recently started learning about fundamental groups in algebraic topology. It worked fine for me until i needed some actual knowledge of group theory (normal subgroups, free groups, generators...) .
What do you recommend as a good reading for group theory?
>>8166961
armstrong is a decent introduction
for all the details you can go with robinson
>>8166961
You could honestly just pick up any Algebra book, and what you're looking for will all be in the first chapter or so. Hatcher also has a sufficient exposition on free groups in the section on the Van Kampen theorem.
>>8167121
thanks, I was looking for it because of Van Kampen theorem
