It would make sense with hypothermia but with hyperthermia, it doesn't.

When you shiver your muscles are creating friction against each other. This is what creates heat. Hyperthermia is when your body is too hot, so you muscles creating more heat would be a bad thing.

Tremors/seizures can take place in certain cases. Is that what you mean? "Shivering" is a response to lack of heat in body. "shivering" during hyperthermia may be something that is superficially similar but not related to true shivering?

is knowing how to compute antiderivatives actually useful? i think it's a waste of time for most people. after taking the integration class you only need to know how to take a few antiderivatives that appear in some exercises. wouldn't it be better to teach numerical methods of integration instead of teaching antiderivatives?
>>
>>7793504
Why would you need to explicitly compute integrals at all? Integrals are only useful to prove some theorems in cohomology, and there you don't compute them but only show their existence.
>>
In many practical situations it suffices to have numerical estimates, but goddamnit if you learned how differentiation works you can damn well learn how to do it backward. Furthermore numerical estimates don't give you neat formulas when those are available, but the pen and paper way does.

Tell me about astrology, why the people still believe in this ?
Do you believe in this, /sci/ ?

Why do you believe this is an appropriate subject for /sci/

TL;DR
>People are afraid of chaos and want to put order into their lives.
>The belief that your personality is determined by the stars when you're born is comforting to some
>The Barnum Effect makes people believe a generic set of statements ("sometimes you need some alone time" or "[your constellation sign]s tend to be critical of themselves") are tailored to them

Although I'm curious as to why a majority of women believe in astrology while men don't

Is misogyny an evolutionary adaptation, along with things like psychopathy, lack of empathy for animals, accepting rape, etc?
>>
>>7793475
Not being feminist does not equate to misogyny. Misogyny is a social construct. Humans have sexual dimorphism. It's fair to say that our base instinct/animalistic nature includes men acting dominant over females in certain ways.
>>
>>7793475
Anyone who regularly interacts with women inevitably becomes misogynist. Only blue-pilled reddit cuck manchild neckbeard virgins will deny this fact. Don't believe me? Ask Chad. He fucks a different slut every night and he knows very well how worthless they are.

Why everything other than math seems like politicized garbage that is merely rehearsed as anecdotal truth. Yet, that's what comes about when the public is nurse on science fictions and news stories about what's going on over in Endor. Math is the only place where a person can explore the philosophy of thought and apply it to the substance. People should look at scientist and media outlet as liars, not peddlers of truth.

"We hold these truths to be self-evident."

Is the fact that most people are right handed a result of biology or culture? Or both?
>>
>>7793316
Yes
>>
>>7793316
your main hand is the opposite of the testicle that hangs low.
This allows optimal scratching and sniffing, it's an evolutionary advantage.
>>
Not proven, but a popular hypothesis:

There is a combat advantage to being left-handed. If you are left-handed, most of your opponents will be right-handed, and you will be used to how they move. But most of your opponents' opponents will also be right-handed, so they WON'T be used to how you move. This is most commonly observed today in sports.

This would create a kind of equilibrium, where the advantage is bigger the rarer it is, which in turn makes it more common, etc. If left-handedness also comes along with certain disadvantages (and there is evidence it does, healthwise), then you end up with stable minority of left-handers.

how do i get into robotics?
can you do anything useful without a relevant degree in robotics but knowledge of coding?
>>
>>7793313

Pretty sure there are robotics jobs in the private sector but its mostly menial wageslave work.

You'll probably work in either maintenance, debugging, software dev, or just button-pushing in a factory that uses robots to do all the work.

But if you want to get in on the real action, you need to enroll in a well known robotics research institute

Sand filters remove particulate matter but not bacterias and toxins. There's large scale(reserviour) purifications methods that uses micro-organisms for water treatement but I'm rather skeptical that this vat would do that as opposed to just being a sand filter.

My maths teacher said this:

"you're always trying to get right to the answer as soon as possible, which is great for job interviews and supervisory discussion, but I know how students like you end up - you will not do well in exams that require careful and methodical work. You need to stop rushing ahead trying to get to the answer and slow down. I'm not saying I agree with the exam system, but I am saying that if you continue like this you will come a cropper at the end of the year."

How do I follow his advice and teach myself to slow down?

>>7793310
Start defining things and ask yourself if your answer makes sense in the context that you're given. This doesn't really help (either you get it or you don't), but at least you're wasting some time for the exam to end.

>Thinking

Oh, don't make me laugh. Thinking is unnecesary when you already know everything.

This is what I have started doing. Write everything really nicely. Let me give you an example.

In a math test, don't write x, write $x$.

The same goes for every mathematical symbol. Write the symbols really, really slowly so that they look really good, almost like if you were using Latex. Then, not only will you be a genius but everything you solve...

Guys I got one question for you.

Assume a world where there live only 12 men and 30 women.

10 of those guys slept with one women.
the two others slept with 10 women (each)

So would you say on average that men have more sex than women? I´m confussed.

Read an articel that women have on average more sexual partners than men, but don´t get it how this is possible. Thx guys
>>
>>7793286
>average more sexual partners

So one woman fucks a larger number of men at least once each, on average, than one man fucks a number of women at least once each.

That said, a man could fuck a few women a lot (5x26), then settle down, and a woman could fuck a lot of men (49) once each, one 26 times, then settle down. 130 for man in 5, 75 in 50 for woman.

Once settled down, their sex would [except for cheating and le :^) cuckoldry] grow equally.

In theory, women...
>>
Think of 3 people. One girl, 2 boys. The girl fucks both boys.

Now the girl has had sex twice and each boy has had sex once.

Now the average number of partners for the woman is 2 and for men it is 1.

Scale that up to like 7 billion. Capeesh?
>>
>>7793286
Maybe I'm retarded, but it's fucking obvious they have to be lying on the survey or the survey sample is too small. It should always be 50:50

Whenever you add a new sexual partner to set of unique sexual partners for one gender, logically you have to add to the other because that pair hasn't slept with each other yet.

Suppose you have 10 men and 10 women (so 50:50 split approximate like the real world)

Let's number each sex 1 to 10

Help me out sci, im studying for a Calc 3 test i have on friday and im having trouble with a problem from the textbook (pic related)
Find the Value of the triple integral;
$\iiint\limits_E \,xy \mathrf{d} V\$
(my latex may suck, its the triple integral of (xy)dV on the region E). Where E is the pholyedron with vertex (0,0,0) (1,0,0) (0,2,0) and (0,0,3).
The problem im having is that the solution on the textbook is (8/3e). i really dont know how you could end up with e on the result.
>>
>>7793227
latex didnt went so bad, just ignore the red part.
>>
>>7793227
oh and btw, what i did was the iterated integral where:
0<x<1
0<y<2-2x
0<z<3-(3y/2)-3x
>>
$\sum_{n=0}^\infty \frac 1 {n!} = e$

How do I read this? Do i have to multiply it for the wavelength? Is it

or
30 * 460 mW/cm^2 (13.8 W/cm^2)?
