Musk's endgame is making a manned colony on Mars. He thinks humans are going to wipe themselves out someday soon and he wants a backup for humanity. A small lander on Mars would only ever be an intermediary step anyway. He's just moving towards his true goals.

It basically is. Why do you think sex-starved young men shoot up schools? Not having regular sex is self-torture and slow-motion suicide.

From an evolutionary perspective, why do so many white women lack the "ass gene" compared to other races? What causes white men to select against the most fit traits for the survival of their offspring and mate?

Big boobs aren't going to do any good to feed your offspring when the mother of your child hemorrhages out and your baby is born a retard from trauma during childbirth.

this mysterious ASS gene is the number 1 factor for childbirth survival for the mother? that's groundbreaking research!

The longest our bodies can survive without food or water for around three weeks if the circumstances are right. Maybe longer with water.

>How is it possible then that people fast for so long?

Angus Barbieri spent 382 days fasting. He survived only on tea, coffee and soda water
and vitamins.

How is that even possible?

>Angus Barbieri spent 382 days fasting. He survived only on tea, coffee and soda water

that's not really complete fasting. It's more analogous to "not eating" for 382 days, or being on an IV drip for 382 days
>>
>>9051487
It's impossible, he had to get calories from somewhere.

I frequently fast, not hardcore though. I will wake up 10am, drink nothing but coffee and water until like 6pm and then have a meal. It gives me mental clarity and focus.

The longest I've gone without food was 24hrs and I was practically starving. I cannot imagine real hunger, and frankly I don't want to go there. But I do fast all the time.

Can someone explain integrals to an idiot? I know it is the area under the certain area of a graph but how is it calculated and how is it the opposite of a derivative?
24 posts and 5 images submitted.
>>
>>9051191
The reason it's the opposite of a derivative is because the height of the graph (aka [math] f(x) [/math]) is the rate of area accumulation. So the integral [eqn] \int\limits_{0}^{x}f(t)\text{d}t [/eqn]
has a rate of change equal to the value of [math] f(x) [/math].
>>
>>9051207
That's just bullshit semantics.

The real answer is the main theorem of integral and differential calculus, riemann and newton integral equivalence theorem and the definition of each of those. There is more to be told here, but I'm alredy bored explaining it for the umpteenth time. There's a lot about this everywhere on the internet.

Is there anyone with an IQ above 100 who questions the modern hypothesis for OoA with partial archaic admixture?
I just feel like it's always some /pol/ guy who doesn't understand things like mitochondrial eve or genome wide similarity.

Why is there no nobel prize for mathematics? I mean, there is a nobel prize for economic sciences … which barely qualify as "science" imho.

I heard some anecdote about Nobel's wife cheating with some mathematician. But somehow, this does not sound serious.

I'd argue the Abel prize is closer to being a Nobel prize for maths. The reason there is no Nobel prize for maths is because Nobel did not think it helped humanity, at least not directly.

Alfred Nobel was cucked by a mathematician.

Is it possible to represent nonlinear systems as linear time-varying systems? I found little papers and no books covering this subject.
Does anyone have some references on that?
I'm interested in both methods for approximating nonlinear models as LTV models and identification of LTV systems from empirical data.

What is the scientific reason why women with braids are more attractive than women without them?
>>
I don't think you can.
How can you represent the nonlinear system
\dot{x} = -x^3
as a linear time varying system?
any linear system you pick will not truly represent this non linear system.
If you are trying to approximate the function then linearize the nonlinear system.
>>
>>9049348
Maybe but would that be useful? You'd just be pushing off the non-linearity to the parameters.

Why do scientists hate philosophy?

I think "hate" is the wrong word...

most scientists don't "hate" philosophy, but find it boring, uninteresting or not important to their direct field

scientists also don't like it when philosophers tell them how to do science

>>9048063
I'm just frustrated how many involved in the science community try to evade the fact that nobody's got an answer for why we even exist. The Big Bang theory doesn't answer all the questions, and there's no reason to pretend that it does.

dude what?
you sound like someone who's annoyed with historians for depicting how world war 2 started, saying it doesn't answer all questions as to why mcdonalds is such a flourishing business.

you may draw some conclusions from it, but of course it doesnt explain everything on it's own.
