What is the biggest selective pressure on modern man, /sci/?
>>9030901
Not being Chad
>>9030901
Financial success
Impulsivity and lack of long term goals
Am I really supposed to believe this?
This is impossible since earth is flat
>>9030891
There are no satellites in space, just under sea cables, ground based radar systems, cell towers, radio waves and telephone lines.
>>9030886
Shouldn't most of the satellites be in geosynchronous orbit at the equator? Otherwise how would I get my TV with my little dish (facing south)?
Only the spy / scientific / gps satellites need to move around like that.
Spaced repetition.
Is it a meme? Does it actually work? Is it the most effective way to retain information?
Anki is the tits. Great for studying.
I still think the most effective route to retaining information is applying it in some way. E.g, using a word in a sentence will be more effective than reading it on 300+ times on anki over the course of a year.
>Is it a meme?
yes
>Does it actually work?
yes
>Is it the most effective way to retain information?
who gives a shit?
>>9030299
really depends what youre study. spaced repetition is very good in general (and here are some papers evaluating study methods if you want) but id say only use anki to memorise specific facts in quite a rigid way e.g. for medicine, anatomy.

I'm an engineer. Hand me a Nobel prize.

That's a lot of mass to move around ...
>>9030003
Carbon nanotubes, very small diameter (enough for analyzer device) should suffice.
>>9029997
You're an engineer and you don't know how stresses and disturbances propagate through material? That isn't a rigid body. When you push one side, the other side doesn't move an inch until the disturbance has propagated to the other side, which moves at the speed of sound.
How much money will it cost me to be part of the colonies when earth is completely fucked in a few hundred years?
you sound like literally hitler

I don't understand why you'd think so anon

They will look into your bank account and make it just one dollar more than you could possibly afford.
Why is it impossible to have a discussion here about the impact of race on intelligence?
Are the /sci/ mods that cucked?

We have too many left wing moralfags on this board. They get triggered if you point niggers are fucking stupid.

I see two or three of these threads a week.
You DO understand they're containment threads, for when the /pol/tards leave their fuzzy hugbox, right?

The tens of thousands of years of evolutionary divergence did nothing
If there's no observers, the wave function does not collapse.
Choose carefully between these 4 options and pick only one, /sci/.
Feel free to elaborate your choice.
imo
I dabble in physics and philosphy for fun, but I really dont grasp alot of things concerning quantum mechanics. What is the general consensus of the scientific community regarding the double slit experiment? Is it really spooky observer stuff or is that a meme? Also what are the main elements in quantum studies that make the field un reconcilable with classical physics? And how exactly does something like string theory solve these problems?
>>9032143
"Observer" has absolutely nothing to do with consciousness. We have this thread every fucking day. Now fuck off back to /x/.
So dark matter apparently makes up 5x as much of the universe as regular matter right?
How do we even know this without even being able to detect it?
Isn't it more likely that we just underestimated the effects of regular matter and it's actually 5x stronger than we once thought?
Dark matter is a meme invented to """explain""" flawed theories
HOW can we EVEN SEE the color black if it implys the absense of light?!?!?!@?$#?@QRHIUGFlkhfw

What does /sci/ think of this study? It would explain a lot of things

>>9030108
Yeah that's what I'm thinking lmao
>Recent genetic research have demonstrated that Neanderthals contributed at least 1-4% to the non-African genome. Aspie Quiz have demonstrated in a large survey in the US population that Afroamericans have only 1/6 of the autism incidence of non-African groups.
Just how deep does the rabbit hole really go?

Yep, it's neat and comfy bookshelf tread. Post your real/digital shelfs, tell us about your major, do you enjoy it or not.
Major: Applied math. Yes, I do enjoy it, though I also love to read books on computer science/physics or any other science. It's just a part of my life.

So fellow humans: are we dying out soon?
And are you just meandering along browsing 4chan day-in day-out or are you actually aware of the power you have and apply it to help shape the history of humanity?
People literate in IT / the Internet are critical. Politicians won't solve anything for us.
I'm just not sure if we deserve to survive but I think probably we'll simply find out within our lifetime.
Fuck your financial ambitions and your daily smartphone, gaming and TV entertainment btw.

Mass extinctions are not instant
a technological civilization is very hard to kill
We're already working on making bases off earth, if there comes a time that there's a very blatant threat to humanity, more money will be thrown towards developing said bases
we got all the tech we need to go full space age, just no political or financial will to do so, since scamming stupid people and making imaginary money off of other imaginary money is more lucrative than benefiting the world
true humanity will die, and those that live will probably be the scum of society and rootless multinationals, but if you want the human species to live on, it is guaranteed that it shall
does it exist, /sci/?

do numbers exist?
Are mirrors real?
Are our eyes real?

in the sense that causality is limited by the speed of light in a vacuum, yes.
We should stop giving government guaranteed loans to people who pick majors that are not economically viable.

it probably works out for the gooks though, she probably has a guy paying for all her shit.
