Why do people care so much about space travel? What do they hope to find?
an escape from crippling depression

Hope
So apparently it's not known if [math]\pi^{\pi^{\pi^\pi}}[/math] is an irrational number.
ITT: We find out.
(-1) = -1
(-1)(-1) = 1
(-1)(-1)(-1) = -1

Is that suposed to go on forever or is it just pi^pi^pi^pi?

OP here, it's just 4.
I'm here setting up a computer while I listen my mother and my sister's bf talk about how ETs are actually demons that come from another dimension, and in a military base they came suddently from the ground and ate the scientists there (and those demons are reptilians), and they claim it has a proven scientific source.
They just don't shut up, I want to punch them, should have I posted this on /x/?

I envy you. I wish the people around me would talk about such interesting things. Instead they only talk about parties and sex. Fucking dimwitted pieces of shit.
Wow OP. So there are two ways to go about doing this:
1. Show them they are fucking wrong
2. Brush it off and ignore it
Option 1 is the 'right' thing to do, but you will obviously get on their bad side. Unless you're lile Carl Sagan tier. Option 2 takes less effort.

You must have shit friends. My friends talk about AI, physics, and science shit. Get drunk with scientists more often it is great.
what should i read after i've surveyed most methods in introductory numerical analysis texts? where do i go from there if i want to keep on studying numerical methods? i don't want to learn about it for any particular reason.. i just think that's what i do best and it would be good for me to learn more
>>8074533
Learn how to use a shift key
>>8074533
If I know about numerical integration can I say that I know numerical analysis?

can u give a good bound on ur error?
Is laziness low blood sugar? Because I am not tired or anything, but I am feeling laziness when I should be reading a simple text.
>>8074497
It's just a lack of will.
>>8074501
Not really, I am reading it anyway. Well, maybe it is, because I didn't care about this bad feel and now I do and expect to solve it. Your answer is pretty shit, though.

Aww. I'm too stupid to get any of them.
Thanks /sci/

Jesus.
The only one I know for certain is, "Brainless but Multi-Headed: Decision Making by the Acellular Slime Mould Physarumpolycephalum)" because I studied them and they are quite amazing at how they do mazes and remember doing them without actual neurons.
What kind of laptop and software does /sci use?
>>8074210
Window 7 + Matlab/Maple/Visual Studio C++/Python
Thinkpad t420 + ubuntu

Asus transformer T200 + windows 8.1 (soon windows 10) + Office 2010 + a lot of ebook
how do you compute an infinite series to prove it is equal to 0 ?

how did we manage to calculate trillions of riemann zeta function zeros with a piece of paper ?
Why do people believe the moon landing was real since we haven't been back since the 70's. Plus you can see that the rock in the photo totally has a marking on it indicating its a prop.
you're a prop

He's an NPC.
> thinks seeing a rock with C written on it is proof that its fake
So what ? We have rocks thats stuff written on it here on Earth, but you don't think Earth footages are fake do you ?
What's the minimum math knowledge I need before taking a Digital Signal Processing course. Do you think three months and two weeks is enough to learn the basis if I work 2 to 3 hours a day? It's some kind of life defining choice I'm making right now.
I mean: are complex numbers & Integral enough to start or I need more basis...

Do you know what Fourier series, Fourier transforms, Laplace transforms, discrete Fourier transforms, and FFTs are?
>>8074021
Idk
Hello I need information for a book.
Do graduate students in chemistry/biology/similar things help perform animal experiments when those experiments actually happen? Like if a university developed a new burn medicine and needed something to test it on, would they use grad students to test it on pigs or something? Pic unrelated.
>>8074011
Yes that is done in research in some (bio)medical engineering fields. But I think mice are more common test subjects than pigs. I haven't really seen how it is handled in practice as I personally worked with much more technical computery stuff but some neighbouring department did, I think.
>>8074011
In the biomedical fields, the grads don't "help". They are actually the ones doing the majority of the thinking and lab work. The Profs are merely advisors. By your second lab year as a PhD student, you probably know more about your research than your supervisors.

who is this fluid druid?
Do you believe that the human brain is truly capable of "free will"? That is to say, our neurons which objectively have no choice but to fire in response to voltage differentials can make up a larger machine that is capable of responding differently to the exact same stimuli?
>>8073991
> objectively
Shit meme
Cogito ergo sum, you faggot
Nope. We're just flesh computers running slightly complex survival/procreation algorithms. Obeying instructions encoded in binary in our DNA.
Which is fine, because if all we are is objects, then that's all the free will we could ever hope to have- will that was predetermined by a part of our physical selves.

What a terrible post.
I have worked out three key reasons why space travel stagnated and I don't think the end of the Cold War or even cost has much to do with it.
1) The lack of super-heavies. Saturn V worked, it could have gotten a base on the Moon and even to Mars. Unfortunately everyone balked at the cost. We then started dicking around with LEO spaceplanes that didn't do much and didn't even work good, thus wasting about 50 years. The Russian story was even worse, theirs plain blew up ensuring that they could never be a competitor to the USA in deep space. People say the...
Comment too long. Click here to view the full text.

I know I said cost doesn't have much to do with it but then said people didn't want to pay for Saturn V but what I mean is that if they had a good reason to pay they would have so cost wasn't the core reason.

Hello /sci/,
My neuroscience exam is on Wednesday and I don't think I covered everything and I feel uneasy about it. Any neuroscientists here to give quick help?
Thanks in advance.
How many hours do you study a day?
ask away
>>8073948
Most of the day. 6 hours.
