ITT: We find a magic square of square numbers.
There's a big price for it, €1000.
What is this and what are the conditions? The magic number could be 1.
>>8040794
All numbers can only appear once.
A magic square is a square where all the rows, columns and diagonals add up to the same sum.

Domain?
It's predicted that robots will replace human labors in future. Up to 50% of our job will be taken over. What will happen to the increasing amount of the unemployed?
>>8049426
favelas or working the land in relatively primitive conditions?
idk
>>8049426
Massive welfare state is the only plausible result

They'll all become gamers, long for and fund the development of virtual reality, and eventually I'll just upload everyone so I can stripmine the Earth into my ever-growing neural array.
It's either that or non-immortality. Personally I don't care which way you arrange your future atoms.

Remembering when /sci/ used to be populated with rational thinkers.
What happened /sci/?
It seems like when people jumped on the fake-nerd bang wagon, they also jumped on the science fanboy wagon without learning what the scientific method is.
And it's not just 4chan either.
Even in academia social sciences are promoted as are theoretical bullshit beliefs.
When did proof go out the window?
When did authoritarianism and false dilemmas become accepted?
What happened?
Most people are prone to psychotic egotism.
They lie all the time because they can't admit to being wrong.
Even when there is proof, like 4chan, where everything is recorded and in front of everyone, straw man arguments and false quotes are used more than anything.
/pol/ and 4chan are populated with psychotics.
>>8058881
Not the guy, but how buttblasted do you have to be to defend /pol/ in every post you see that mentions it? You aren't making any difference here, you might as well go back there so you don't waste time being upset at other people's posts.
>>8058881
Where does it indicate I'm a SJW?
How is promoting science and the scientific method shitposting?
Why do you think I'm stinking?
You're psychotic.
A new poll shows that the way you ask people about evolution can drastically change their response.
Researchers show that when the word “human” is replaced with "elephant” in the evolution question, 75% of Americans agree—about 25 percentage points higher than before.
>>8058041
learn to post links when you're citing something pls.
Sounds interesting. Post link!
>>8058041
evolution is not a fact, it's a description.
Believing in something is called a religion.
It's safe to assume that women are on their own mental category?
I don't want to mean they're mentally inferior, but we can see the paralel between women and male sports and how women world records are actually the same of a 13 year old male athlete and they lose to 14 year old males.
So, following that sense, can we assume that women are mentally inferior to what we consider male mathematicians and male scientists?
Has there been any case in history of science of a female that can be at the same level male geniuses had been?
I'm...

Marie Curie
But for God's sake, 99% famous scientists and inventors in the last century was men.
Now 90% of the persons that change the world are still men. Women can go to the fucking dumpster.
>>8057825
what was her IQ?
what's the posibility of to find another female like her?
>>8057815
Yes, the typical woman operates on a lower level of consciousness.
Let's do the following fun experiment:
Take any of the following categories: science, math, art, literature, philosophy, politics, sports.
Make a list of the 10 greatest males in that field.
Make a list of the 10 greatest females in that field.
Now make a list of the 10 greatest _persons_ in that field.
How many females are in that last list?
The problem is that women are by nature purely sexual beings and emotionally...

Why haven't we detected alien life yet? Imagije how the human society will look like in 3 BILLION years and tell me we wouldn't left detectable traces for any remotely intelligent life to detect in the entire galaxy or even control the growth and spread of all alien life.
So why can't we find anything?
And remember your explanations needs to satify not only one alien species but ALL alien species including future humans colonizing space.
You assume that super intelligent species would want to expand and spread everywhere like a bunch of monkeys
>>8052431
We do
You assume that NO super intelligent species ever would want to spread everywhere
>>8052424
Could it be that all life tries to kill itself before leaving for the stars?
Could it be that we are some of the earliest 'Smart' life out there.
Could it be that Aliens don't want others to find them because we are all doomed to killing each other off?
Could it be one alien per Galaxy.
Could X/ be right and there are aliens and our government is keeping it quite?
Well, /sci/?
Yeah that is a nice drawing well done
>>8052054
0.75^5 = 0.24
Therefore greater chance to negate all damage on bottom row, since 24% > 15%
Anything else?
>>8052076
It's 1 - 0.25^5, idiot
A new language is created that only uses the letters A, B, C, D, and E. A sequence of letters is called a word if it does not include the same letter twice in a row, and it does not include two vowels in a row. How many words are there in this language that are 10 letters long and that begin with a vowel?
How does /sci/ solve this?
>>8058064
by writing all the possible words and counting.
i really hate combinatorics problems
0 . You can't have words 10 letters long with no repeats allowed and only 5 letters...
Was it an inside job, /sci/?

> fuel has a max burning temp
I bet I can get it to burn hotter.
>>8057367
The whole thing was a hoax, the towers are still standing. If you don't think it's possible then here's your reminder that David Copperfield made the statue of liberty disappear, the USG obviously has better resources and better tricks than David Copperfield.
>>8057367
There less energy losses the larger temperature we can get. Fuel burn produce energy not temperature. If it is contain in enough small volume we can reach really great temperature.
What ways are there, even theoretically, to stop a kinetic bomb travelling at relativistic speeds from impacting it's target? (Assuming you are at that target)
Assuming the object is about the size of a 757, could we launch large spacecraft past it to knock it off it's trajectory via gravitational interference?
>>8054342
How far away can we intercept it?
>>8054342
rip
>>8054342
Currently we have no reasonable way to even detect such an object in time to take any counter measures.

I think you mean 'posthumanism'.
>>8051871
Posthumanism is when you fuck around with uploading and other magical bullshit.
Transhumanism is just getting robo legs or whatever.
>>8051871
They're apparently two different things, though transhumanism can result in a posthumanist civilization.
If space is infinite, then gravity waves at the edge of the infinity approach 0. At 0 gravity wavelength, we have 0 space and time. This is absolute 0 of space-time values.
but space isn't.
>>8056781
How do you know?
>>8056779
gravity waves' intensity decreases quite rapidly, so it approaches 0 much before universe's edge
Do you ever get the feeling that cosmology has gotten so far down the wrong track that it's not even wrong?
>>8056703
QM, QFT, String Theory, M-theory and Chaos Theory
I don't believe half of what theoretical physics says, I think it's mostly nonsense, especially things like "time dilation" - if anything happens the molecules slow down, in my opinion you are changing the normal definition of time otherwise in a senseless way. There are signs of this sort of "heresy" starting to trickle into the highest authorities of the science, which is never a good sign for it being right. I just wish they would stop experimenting with things like the LHC because sooner or later a mistake or oversight will be made and it'll...

>especially things like "time dilation"
You say that but a big reason GPS works properly is because the clocks on the satellites correct for time dilation. It's definitely a thing.
You have 5 seconds to prove to me why anyone should ever bother learning, understanding and memorizing all the complex functions, rules and ideas behind this decrepit, inane, obsolete study of chemistry
it allows you to literally play with nature. You can make drugs, explosives, medicines, materials, etc...
>>8052494
Sounds like you've already judged it before learning anything about it. Typical brainlet.
>>8052494
because mathematicians don't have sweet labs and some people think physicists messing with lasers is outright boring.
My senior research was on organic chemistry; think about how frustrating it is to try to create something from a simpler chemical, then walking down to the NMR downstairs and BOOM you find out (by literally solving a puzzle of data) that you've successfully synthesized your product. As hard as it was, it was the most challenging and rewarding experience of my life.
