What is the probability that there is civilization elsewhere in our galaxy simply too far removed for us to ever contact?
39/331
>>8150421
About 50%
if we assume there's another civ at the opposite side of where we are then it takes 200,000 years for us to communicate. That doesn't mean it's impossible just really difficult.
If the only goal of evolution is for an organism to survive and reproduce in its environment better why have organisms become so much more complex over time? Can anyone really make the case that complex organisms humans are better fit to survive their environment than bacteria and other prokaryotes?
*complex organisms such as humans
Sorry about that.
>>8150353
Competition from limited resources.
Complexity arises from biotic stress, e.g. competition between organisms. Limited resources "force" organisms to use same resources more optimally or find new resources. Finding new resources and new ecological niches requires often more complex behavior than just reproducing every 20 minutes.
A two-trick pony is more likely to gain more resources than a one-trick pony. A three-trick pony will beat them both at gaining resources. Increasing the organism's ability to make more complex structures and functions demands cooperation between cells, and that's...

Do you believe there is a distinction between appearances and things-in-themselves, i.e.. objects as they appear to us and objects as they are in and of themselves?
>>8150343
are you fucking retarded
>>8150349
Is that a no or you are just trying to be edgy like a 12 year old?
>>8150343
I think the concept of "thing-in-itself" is bullshit.
How do we effectively achieve immortality? Ancient alchemists always tried to create the elixir of immortality but they failed to do so.

Ain't gonna happen, sorry bro.

Why not? Surely we can achieve that level of technological advancement

Someone over at /pol/ posted this question
>>>/pol/77657495
... does there exist a surjective polynomial function R^n -> R_{>0} for some positive natural number n?
Want to try yourself? I think I might have a proof.
>>8149427
sum of the squares of coordinates.
>>8149429
It's supposed to be R^n --> (0,\infty) but the sum of squares is zero at the origin.
>>8149430
please restate the question. I still dont understand.
Is there a link between race and intelligence? Like, after controlling for any other variable. Does similar income and environment produce less intelligent Blacks than Asian or Whites?

>>8149248
nope
there's only 1 race, btw
>>8149248
Yes, that's likely.
Further research is needed though, we don't have a lot good data. It doesn't help that psychology is so soft, so data is likely to be pretty noisy. Remember the crisis of replicability.

Space colonies anyone?

How do you fill a black hole? Can you?
>>8148254
By shoveling dark matter into it equal to its volume.
>>8148254
Throw your brain into it
Black holes aren't really holes. They are objects (probably a sphere) of super dense material. By throwing anything into it, you are just adding the mass. One could destroy black hole only by starving it of matter, until it evaporates by Hawking radiation

Why do humans adore lions?
I can understand feeling more sympathy for mammals than reptiles or fish, but why is a man-eater universally admired?
Because in the wild it represents power and might. Also they look majestic, time to grow a beard anon.
![cat-getty_0[1].jpg](https://i.imgur.com/qj4WJUS.jpg "cat-getty_0[1].jpg")
coz they're just big cats
humans liked lions for thousends of years ( since the roman empire)
Its just a popculture thing

They just reached the kickstarter budget for observing KIC 8462852 for an entire year from the Las Cumbres Observatory Global Telescope Network. Which means it will do nothing but watch the unusual activities coming from the Tabby's star to figure out what's going on with the dimming.

It's confirmed that it wasn't an alien megasctructure but my money is still on the comets. What you think /sci/ ?
>"Where's the Flux?"
>Not "What the Flux!?"
Missed opportunity
>>8146541
I science in America so underfunded that they need a kickstarter to make an observation campaign? It's really that bad?
>>8146560
It's not that science is underfunded, even though it might be, but the telescopes have lots of other places to look at and using them aint cheap. So they pretty much gathered enough budget to rent the telescope to look at KIC for a year.
America is already feeling the pressure of India's superior science and math skills and is propping up their tech companies with H1B visas. How long before this system collapses and Indian universities start ranking in the top 50?
they will be good at biology, straightforward chemistry, and theoretical physics. Apart from that, Indians are shit tier at problem solving. From my experience in academia, the only successful indians are the ones who grew up their entire life in the states. The ones from India can work all day and night but they dont have any critical thinking ability and can't solve practical engineering problems.

so like rote memorization... how is that different than the usa education system?

something the us does must be working because they see a lot more entrepreneurial success on an international level
What's your opinion on human dignity and pride /sci/? Is it simply a product of our culture and has no real meaning or value?
>>8158646
>product of our culture and has no real meaning or value
Elaborate
>>8158650
I mean that if we were not a 1st world society or whatever we are, then no one would give a shit about the concept or human rights or maintain the whole "Dignity above all" attitude.
>>8158656
Oh, I see. You're asking if it's just a social construct (like race).
The things you mentioned have somewhat nebulous definitions. I don't think we can rule out the possibility that some components of those traits are just social constructs and some components are not.
Personally I don't believe pride is anything more than a social construct. Dignity is somewhat more complex. I think that even if it is a social construct, it may also be a theoretical cultural ideal. This would mean...

Homo sapiens are anatomically similar to frugivores, more so than omnivores.

I find archaic humans endlessly fascinating.
I find it really hard to find good quality audio/video lectures or even audiobooks on the subject. Can anyone recommend any?
A couple I can recommend are;
Lecture series
>Rise Of Humans Great Scientific Debates - Prof. John Hawks (is a jew though)
>Human Prehistory and the First Civilizations - Bryan Fagan (is a bit dated)
Audiobook
>A Troublesome Inheritance - Nicholas Wade
>The Strange...

I'm a strong proponent on multi-regional evolution and believe 'out of africa' meme will get BTFO as garbage in our life-time.
>>8156909
Don't forget the Kumari model, though that one's a bit farfetched.
Also, I'm honestly ok with the idea that we came from Africa.
What's /sci/ favourite (ball) pen or pencil to do science?
Pic related. They are cheap and just work.

None, I cut my finger and use the blood as a substitute for red pen.
