Why do patients who suffer from a palsy of the biting muscles (like car crash victims) experience a shortening in interpupillary distance?

Can interpupillary distance be widened by strengthening the biting muscles?

I have a two part question for you /sci/, which you probably have been asked before:

1) Is it true that the majority of, or a large number of, people within STEM have some from of high-functioning autistic spectrum disorder?

2) If so, in which fields of STEM is it most common and in which fields of STEM is it least common?

Pure math here. Don't have autism. I would say about 1/5th of my undergrad math cohort had some form of autism. In grad school that dropped to just a few.

I think physics has the most autists because it's theoretical wankery but to them it "has a point". Sperglords can't understand the beauty in math for math's sake.

>high-functioning autistic spectrum disorder?

If this were to be true then that is a misnomer and should be renamed to 'average-functioning and smart but lazy-function autism'

In a classroom of 50 people you would be lucky to find a single one who is even remotely intellectually ahead of the curve, if by the curve you consider the average potato farmer.

You roll a 1 kg ball with no coefficient of friction down three slopes of angles 20, 45, and 75 degrees respectively.

my conjecture is that the x coordinate of the ball increases at the same rate no matter the angle of the slope you roll it down.

Why does my body signal I'm not thirsty/hungry immediately after I've drank water/eaten food even though I haven't digested it yet?
Is my brain lying to me?
Is it just to quickly inform me that "food in throat when stomach hurt = good" as if I didn't know that already?

First, OP, get an idea of what "hunger" really is.
It's not your cells telling you they need energy
it's just a feeling, your body telling you to eat something, nothing more
with a bit of training you can entirely overcome that feeling but that's another story
it has nothing to do with digestion or chewing food

Just watched Varg's newest video about home schooling. Is home schooling or even no school at all still better than if kids attend at regular school? Speaking for myself (German) I can agree that I spent 6 hours the day just sitting in the class and being bored. For several years. I've only learned for the exams and thats it. Now doing my master's course but I don't attend at the lectures and just learn at home instead.

What do you think about that?
Unfortunately homeschooling is illegal in Germany since after WW2.

Nun mein Freund (als Deutscher antworte ich dir...)

I don't think most parents are capable of home-schooling. A lot negative sideeffects will be the consequences. Like, you don't really socialize with your peers, you don't have a counterpart and the most important part - nobody is checking on the quality.

It's okay in University when you know that you won't gain much out of lecture and the learning itself will be on your own part. You attend the lecture to ask questions and maybe filling gaps in your knowledge but the real learning is outside the class.
The professor gives you a outline and the exercise, repetition and so on will be in your hands.
On the other hand, the school-system is built on to teach people already in class without much self-learning. They are two differents concepts and thus you can't really compare it.


Nun, wie gesagt. In der Schule lernt man in der Klasse, während man im Studium sich so oder so sich sicher mit dem Stoff alleine beschäftigen muss. Ich glaube nicht dass die meisten Eltern oder ähnliches eine qualitative Ausbildung garantieren.
Sicherlich kann man bei uns auch einiges optimieren; allerdings ist man hier sicher, sich an ein Modell und Lerninhalte zu halten. In der Uni hat es mir auch nicht gereicht nur durch Anwesenheit irgendeine Klausur zu bestehen.

Most of those who home school are idiots who are learning along with their children. Most of them do it for religious reasons (even Catholic schools teach evolution), and the children come out of it weird because of their lack of socialization.

/g/ doesn't know shit about tecnology so i'll repost here

Electricfag here

>Solar energy.
We know the hardest thing with enery is how to store it, so since solar output is at it's peak during the day when demand is low and vice versa demand is high during night when no sun is up, why don't they use the exeeding electricity during the day to divide hydrogen and oxygen from water, store hydrogen and burn it back into water during night to produce energy?

Same quantity of oxygen is produced when extracting hydr. than you need to burn it back into water
No CO2 emission
Ofc no 100% efficiency but is still better than expensive big ass lithium battery in each house

Tell me why i'm an idiot /sci/

Do insects feel pain?

Discuss.

Biology student here, I think that insects only process pain, withouth "feeling it"; they don't have noxiceptors, but they surely have a sense of self preservation, they can sense the ambient they're in and if it is right or wrong for their living.

Even unicellular organisms can sense the ambient they live in.

So terriforming Mars won't be a thing for quite some time, however it got me thinking about some ways we can adress some of the problems associated with terriforming.

>Microgravity
Not much you can do about this, other than build structures that could take advantage of it. More research needs to be done before I comment on the biological effects it has on lifeforms.

>Atmosphere
There's been a lot of different ideas ranging from nuking the icecaps to transporting air. What do you guys think? What about basically building factories and just driving cars around to put as much greenhouse gasses in the air? It'd take a while naturally, but the Martian climate gives us more freedom to do what people complain about what we do here. After we induce a greenhouse effect we can start growing plants outside to drink the CO2 and produce air.

>Magnetic field
So the solar radiation stripping away the atmosphere is somewhat of a problem, and the fact the Mars doesn't have a hot churning core doesn't help matters. Would you think it's possible to introduce an artificial ring system around the planet made up of a magnetic cloud?

Anything I missed? Again the terriforming scenario is a ways off but it doesn't hurt to come up with useful solutions ahead of time. Plus I'd like to here your opinions on this.

It amazes me how many intelligent people talk about going to mars, and hoping to live out their life and die on mars.

Why not terraform the Sahara Desert? Or the North Pole? Or the Marianas Trench (or whatever it's called). All of those would be easier and would accomplish something.

Elon Musk should just shut the fuck up and load a winnebago with whatever he likes, and drive out into the Sahara until he runs out of gas. At that point, the only assistance would be some other suicidal freak in another winnebago under the same rules. No rescue operations permitted, same as it would be if Elon got his dream come true and went to mars.

>terriforming and colonizing an alien planet is pointless, but building an underwater city in the darkest, most pressurized place on Earth is a worthy endeaver.

Honestly anon, I agree that trying to terriform our deserts is something worth doing as practice, but only for prepping for the real journey of Mars.

It's quite frankly ridiculous that you think it's ridiculous that people want to travel through space to live on another planet so they may produce the first martians.

This is the manifest destiny of our time, you either want to be apart of it or you don't and that's fine, but don't sit there and judge and act like what you decide to do with your life is anymore superior that what I decide to do with mine

Why is an empty set considered a set? How is it justifiable? If a set is a collection of distinct objects, how can you claim it's a set when there's nothing distinct its a collection of?

A set is like a box. An empty set is just an empty box.
>>
It's the collection of no distinct object(s).
Just imagine two baskets. One is empty, the other one has the element {Calculator}.
In one basket is nothing, while the other one has a Calcalator. The empty set is a collection of no objects.

More {} = A \ A.

What's left if you take everything out what you have in it.
>>
>>8161213
>>8161215
But the box is an object whose essence can't be identical to set's. The box won't stop being a box if it's empty because it doesn't mean for a box to be box only if it contains something. The definition of set is supposedly for it to be a collection of objects. Shouldn't it be meaningful to call something a set only when there's something it's a collection of?
