Why doesn't /sci/ have a janitor? We get these stupid fucking gorilla threads EVERY DAY posting philosophical crap that belongs on /x/ or /his/, but I've never seen a single one deleted. These threads are nothing but shitposting, why can't we have a part time janny working multiple slow boards?
>>8217760
Mods are busy deleting threads about differences in intelligence between races.
I've given up about that long ago.
Good luck telling the mods, m8.

They are on topic. Deal with it.
Would it be possible to use evolutionary means to find alternative equations to stuff? I got inspired by the story of the dude who used evolutionary method to find aerodynamically efficient designs for cars or whatever.
Is it even a good idea? Does it have any use? The problem I'm running into is that I need something to check against, to make sure the equation moves in the right direction, defeating the whole purpose of it. I mean you might want a different one to be able to derive shit, but you have Taylor expansion for that, no?
Apart from the obvious constraint that it will only be accurate within the range you specify if you want to add a constant, which you must for some equations.
You'd probably just end up with imperfect infinitesimal mathematical equations
>>8217791
Of course they'd be imperfect, I'm working with margin of error here. I also already mentioned I need to specify a range to test against, so for example if I wanted to find the formula for a square, I need to specify a range the testing equation of x^2 can have, to compare against the evolved equation.

What does /sci/ think of eugenics? Could we breed better humans?
Yes. But not now.
>>8217591
What about now?
>>8217626
You didn't even ask how, so I assume you are entitled to an opinion. So you have created this thread so you can spout your dumb propaganda over here.
Take your dumb propaganda away
If you do not accept undisputed cubic measurement, and your enemy does, by resuming the status quo, you will lose at the end of the day.
Cubic thinkers are smarter than you, those who influence cubic thought, more courageous.
The concept of a 'cubic plane', must be introduced to counter cubic misconception. Proof of a 'cubic plane': a square in a cube.
4 sides of a cube can be grouped on a single 'cubic plane'.
In any case, there are 2 sides ungrouped.
A cube has 4 side and 2 polar.
>There is not an entity or group in this universe that disagrees, bar word-mammals who conceive a cube as having 6 side.
>>8217479
Cubic plane curves are pretty cool. In particular if they're non-singular. Algebraic geometry thread?
>>8217494
Make of it what you wish, but answer me this, do you agree with the logic in the original post?

A Lunar Station with mass driver to accelerate mining robots to asteroids near earth
And a second mass driver to cheaply accelerate into low earth orbit.
Fully Automated mining robots could be build by 2019 at current rate of progression in robotics and Ai.
When do you think will there be a lunar space station?
What structures do we need?
Are O'Neill style structures feasible with a lunar space station?
Will it be ready be mid century to counter the wide resource scarcities?
/sci/entists propose
1.) date for the first module on moon
2.) date for the first resources send back to earth
3.) A cheap concept to realize a mass driver or similar structure
1.) First module could be send as soon as the public thinks this is a good idea.
..Or investors recognize the potential
2.) resource scarcity will hit full force in ~2030. So hopefully by the end of 2020 we will have the infrastructure in place to not slide into crisis/recession
3.) a railgun would have the tremendous advantage, that it would allow to send stuff from the moon to the earth if the earth is at a lower gravitation potential (sun - earth - moon)
And sending stuff into the asteroid belt by using the moons tangential velocity when it comes back from a lower gravitation potential compared to earth (sun - moon - earth)
>>8217461
>current rate of progression
that's stupid
you could build a primitive mining robot today.
but nobody is building a primitive mining robot, meaning that there is no progression.

You can't just spout horseshit online. Someone will come along and tell you to fuck off.
Fuck off.
welp, I proved the Collatz Conjecture.

So go get your $500.

I always dreamed of proving something important and instead of taking credit, just posting it anonymously on /sci/

how do you figure that one?
>A bat and a ball cost $1.10 in total.
>The bat costs $1.00 more than the ball.
>How much does the ball cost?
This is what happens when you get over-educated mathematicians that have no fucking clue what is going on. The Answer is clearly ten cents.

I currently find myself in a state where I have nothing at all on my mind in relativity to your subject, so take my announcement of declared phenomena as a response, reaction, and rebuttal to your statement. Your thoughts have been acknowledged.
x+y=110
x+100=y
The rest is trivial and left as exercise to the reader.
Imagine how much we could learn about the human mind if we were allowed to take a few newborns and use them for experiments. I am not even talking about torture. Just things like:
>take a newborn
>put him inside a white room
>don't contact him ever again
>raise him like that
>take a newborn
>constraint his body
>but give him all kind of stimulus through some kind of occulus rift or whatever
>raise him like that
We can't do it because apparently a dozen of human lives are too sacred. Yet you see all the time all kind of reckless behavior as a society that's clearly more harmful than these experiments and nobody cares.
>>8217082
What is supposed we are gonna learn from those experiments?
What the do you expect to learn through that garbage?
>>8217082
I'm pretty sure someone is already doing it in China or wherever.
Why am I me?
Why was I not born a Pterodactyl in the Jurassic Period 200 million years ago?
Why was I not born as a termite in the 15th century in Western Europe?
Why was I not born in another galaxy far away, on another planet capable of supporting conscious life?
Why am I not a jellyfish, RIGHT NOW, in the ocean?
Why am I alive right now? Shouldn't I-statistically speaking-be dead right now? How many lives have come before me? Trillions upon trillions upon trillions (if you take into account all life in the universe). So why right now? I should be long, long, long dead by now.
Why am I a male human being in the United States on Earth in what we call 2016? When I die will this random dream finally be over so I can rest like the trillions of insects that have come before me (and the millions that have died by the time you're done reading this post)?

Science is a subset of philosophy, I think this board is for science and math (and occasionally the mathy parts of computer science) and not the other parts of philosophy.
>>8229982
Can this problem not be approached empirically?
Why do this just get swept under the rug and elicit nothing more than a muttered
>uh...Idunno..
and a shrug?
I can't find anything substantial on the internet about it despite it being one of the most important questions that can possibly be posed.
I don't know if this belongs here but I was taking a picture of the moon last night (multiple, actually) and the little glowing circle kept showing up no matter where I took it.
tl;dr what is that next to the moon plz
It's either a ufo or a reflection due to shitty optics and overexposure.
>>8216936
all for UFO ggwp
Are you dumb? Is clearly an ayyy lmao spaceship
So what the hell is the difference between all of these things?
>Does not exist
>empty set
>indeterminate
>undefined
>0/0
>c/0, {c|c=/=0}
Are any of these things the same?
Does not exist = is an element of the empty set
Empty set = The unique set without any members
Indeterminate = cannot be determined
Undefined = is not defined/does not have a definition
0/0 - division by 0 (this is an example of something that is undefined)
C/0 - division by 0. An undefined.
>>8216929
so would it be correct to say
lim x=>0 (|x|/x) = {}
or instead of = use the pic related
>>8216939
Jesus Christ no
How would First contact go about: Between human and a alien that is able to communicate back?
Ayy lmao
>>8216772
I wonder how they would interact with a species that only talks in meme's
>>8216769
You mean actually conversing between the two species? Why would that happen?
Why are cats not scared of insects? Should I get one to watch my house?
cats are predators that hunt insects.
yes, get a stray one or adopt.
>>8216322
size difference
it's why elephants are afraid of mice too
>>8216326
This.
Cats will seek and destroy insects, bees, wasps, mice, bats and any kind of pests or vermins they can get their hands on.
They will also try to kill your in your sleep but its okay cuz they're cute :3
how could one create a permanently floating building or town?
buckminster fuller proposed a huge lightweight geodesic sphere, lift by hot air. But it would have to be enormous
budget within 10 billion (aka, 2/3 the cost of 3 gorges dam)
Permanency doesn't meaningfully exist, especially on a macro scale.
>>8216216
Why? So it could float around and drop shit all over everything underneath?
>>8216225
This. There might come a point when you want the thing to just fuck off.
been interested in learning programming, looked at the /sci/ wiki but i didn't think any of the books were what i was looking for.
any book recommendations would be helpful to get me started. also any recommend languages to learn, I've learnt some python and know enough to make beginner programs.
depends on what you wanna use the programming for
also, ask /g/
>>8216168
i guess i haven't thought about what i would use it for, but say i was to go into statistical programming with languages like SAS is it better to start with SAS or something else?
to learn the fundamentals of actual programming, like how to think about programs in an intelligent, wise way: SICP. it's an excellent introductory textbook to programming
>statistical programming
learn R
