Scientific mystery: why do men and woman compete separately in pool/billiard? It does not require any particular physical strength or endurance.
>>8768163
I am former champion pool player and have thought same thing. Pool/ Billiard is a game of Brain & finesse not Brawn & gender has nothing to do with it. and games should be completely nongender determinate.
Are there any psych people here? Let's have a mental health thread!
I myself have recenty been diagnosed schizo... :/
What can you tell me about schizophrenia? Is it possible to give yourself schizophrenia? Either through drugs or occultism? Is it possible to be cured without medicine? Is it possible that schizophrenics perceive things that others are not aware of, perceive too much?
Once you've developed schizophrenia you are not longer /sci/. Please move on to /x/ and have fun on your journey, friend.
>>8768401
YOU'RE A DICK!
Mental health is science
>>8767937
If you are genetically predisposed to so, you can develop schizophrenia by taking drugs.
How to get more girls into STEM?
>tfw no one cares about young boys interested in stem
>>8767493
it's about driving wages down by making the employment pool larger. right now they are tapping into about half of what they could be tapping into if they can get more women into STEM. companies also get tax intensives for hiring minorities and women.

There's your answer. Women get excited by retarded shit.
>life originated in the sea
>then there are sea animals, which stayed in the sea, and ground animals, who came out of the sea, and amphibians who are weirdos anyway
But how the fuck do you explain flying animals like most birds? How do you "evolve" to that? You jump a lot until your great-great-great-great-grandson ends up flying?
> land animal
> can flap arms a bit to control fall or swim
> get a bit better at flapping arms
> get a bit lighter each generation
> flying animal
Truly inconceivable
>>8774820
Consider that sharks are older than trees
Also there's evidence of transitionary fossils, evidence of dead ends, amd of course the fact that multiple types of animals independently evolved flight many times. indeed there are "inbetween" animals like flying squirrels that are land animals that can glide long distances, to give you an idea of how a transition might occur. Or we can look at flightless birds that evolved from flying animals - they adapted to not need to fly anymore, just like some animals adapted to fly in the first place.
Just because you can't wrap your head around large time scales doesn't mean you're correct to assume its impossible.

Not a big jump from there. All these steps follow from one another and foster a gene pool that is already close to "can fly on its own power".

Hey, /sci/. I'm a brainlet and a globecuck, but my friend is a flathead and they sent me this maymay.
Apparently the big picture is from an actual satellite (nasa.gov/feature/goddard/from-a-million-miles-away-nasa-camera-shows-moon-crossing-face-of-earth)
The small picture is "not a photograph, but a still from a CGI recreation created by NASA Goddard in 2013 using measurements taken from Apollo photography and mission telemetry, combined with hi resolution LRO data." The size of the earth is much the same as in those photos, though, and that's the important part.
What I want to know is, why is there such a drastic difference in the sizes of Earth? Has it to do with the lens or something?
Th-thank you in advance.

And why do you say the 1st photo is fake, and the 2nd is true, when they said that both are accurate?
Hopefully this will help.

What does this imply about the true relationship between "intelligence" and IQ scores?
Not to defend IQ tests, but why shouldn't a machine be able to show "intelligence"?

I never said that. But now you're hinting at a better argument than "this test is bullshit because a machine can do it".

Just copy paste the physics curriculum for a top university and read that. Pretty much all of it can be self taught except for the practical stuff. I personally don't attend lectures or lessons except for the first one each year (it's obligatory) and get mostly As.

After all the bullshit going on here about IQ. My hypothesis is that anyone >110 IQ(above average), good socio-economic background and good work ethics can make it into competitive courses like medicine, law and architecture and simply practice them in reality. However, if one decides to go into research, let's say, a Ph.D. in mathematics, one without a decent level of IQ will find it very difficult to see patterns and understand complex novel scenarios in the field.
My university entrance exam is the A levels. People breezing through school and getting A*A*A*A*, both you and I know are an exception rather than the norm, probably less than 0.9% of people get this grade, imagine how many within that get it without working much. The average IQ for medical students is 115, the average score of a medical student is AAA(Typical offer for medical school), so connect the dots, and holy fucking shit, IQ doesn't mean shit until you get to Ph.D. level. Even in MD programme, where memorizing is the game, IQ doesn't play that big of a role anyways.
Tl;dr stop blaming your fucking IQ and get your ass off the couch and start working. Work ethic and wealth is the key here.

A thread for discussion of different CAS's. What are pros and cons of each? What do you use? What is the most valuable to learn?
Maple - http://www.maplesoft.com/
TI-NSPIRE - https://education.ti.com/en/products/calculators/graphing-calculators/ti-nspire-cas-touchpad
Sage - http://www.sagemath.org/
MATLAB - https://www.mathworks.com/
Sympy - http://www.sympy.org/en/index.html
Mathematica - https://www.wolfram.com/mathematica/
I've played with MATLAB and Mathematica, but really want to get into Sage. (Open source is just sexy.)
>>8773840
I really want to find one CAS that works well and just bite the pillow and become really comfortable with it.
I think sympy might be the best option, not sure.
depends on your major
if engineering then matlab coding will be required for most of your courses
on the job you will need to be good at a regular language and one of the 3m programs
math/physics people will go with maple or mathematica
i can do everything with maple and prefer the way it type sets papers
also matlab if more for numerics while the others are for decimal computing
but you can use any of them to accomplish any task
even if something is easier in matlab (sparse matrix) i will still use maple
more similar to matlab are scilab and octave

Hey /sci/, I've recently taken in interest in the extremely far future of the universe (after 10^50 years)
Apparently, there's a chance that protons are unstable with half life of ~10^30 years, which means that all matter might decay
But more interesting is what happens if that's not the case. If protons are stable, all matter in the universe will slowly be converted to iron through cold fusion (which is possible because of quantum tunneling)
It'll take over 10^1500 years for the process to even be noticeable though.
Anyways, the reason why I find this so interesting is because the newly formed iron will clump into spheres, creating iron stars, which will be the last large structures that will ever exist in our universe.
Neat, huh?
>>8773826
>all matter in the universe will slowly be converted to iron
Wrong. There are plenty of elements heavier than iron (gold, mercury, etc.) that will never become iron. Since the statement i quoted is false i can reguard the rest of your entire statement as also probably false.
Neat, huh?
>>8773845
>Anonymous 03/24/17(Fri)09:45:58 No.877
>>8773845
Those may or may not break down. The point is the overwhelming majority of matter will be iron, even more than hydrogen in the universe today.
If you're wondering why the iron can't fuse into something else, its because after iron, fusing nuclei isn't energy efficient anymore, meaning it would involve going from a low energy state to a high one, which can't happen spontaneously
Also, you can research something before immediately discarding it
https://www.wikiwand.com/en/Future_of_an_expanding_universe#/Future_without_proton_decay
>>8773864
Im fully aware of why fusion stops at iron. The problems i have are:
>all the matter in the universe will be converted to iron
Already explained that one. Not to mention the last remaining stars may go supernova making the percentage of iron even lower. All you can say for sure is the majority will be iron or heavier.
>iron stars
Is just plain retarded, i dont feel like i need to explain why.
>newly formed iron will clump into spheres
Also wrong. It will get blasted out into the universe as the star dies. Or become a black hole. Either way you are looking at iron asteroids flying away from eachother and a few black holes here and there.
