How does social science work?
Do social scientists develop theories and put them to test, by making verifiable predictions?

>How does social science work?

You become a grad student, you suck up to your Professor's political ideas by writing papers that confirm their own biases, get respect by your superiors, become a professor yourself and then push your ideology into the next line of students.

>Do social scientists develop theories and put them to test, by making verifiable predictions?

Some time ago they did, until they realized that science, specially fringe fields no one cares about, has no checks and balances so you can publish whatever as long as you p-hack it enough.

The wage gap is a good example of that. Literally made up.

Dark matter is bullshit right? I mean, there's obviously something going on. But astrophysicists are like "lol obviously there's shit there WE JUST CAN'T SEE IT" sounds like "lol idk" to me.

What is more likely: most of the mass of the universe is impermeable, invisible and immeasurable, OR gravity is much stranger than astrophysicists think? Since we don't even have a probe far away enough to measure gravity in other star systems, how can we say we "know" it's not gravity and must be this invisible "dark matter" that's just all over the place.

checkmate atheists.

Dark energy is bullshit. Dark matter is just matter which is not illuminated by light, although the exact amount is debatable.

You should read a bit about MOND, or about Erik Verlinde's emergent gravity theory. It totally ditches dark matter.

just wait until you see the Korean students.
when I was an undergrad, there were five or seven South Koreans in my dorm who we saw in the hallways now and again, but who never hung out with anyone else. and then there was, like, one Korean guy who hung out with the rest of us but didn't talk to the other Koreans. apparently it was kind of a religion thing? I guess Korean churches can be kinda shun-the-nonbelievers at times.

As opposed to reductionism, emergentism argues that there exist emergent properties in the world not reducible to some set of more basic properties. Crucially, this is very much linked to systems science. Anyone here work in systems science (systems biology, systems neuroscience, etc.) care to comment on their views about reductionism?

Why don't they use more than just 0s and 1s for computer? Let's look at all combos of 0 and 1
00
01
10
11

Now what if we had 0, 1, and 2
00
01
02
10
11
12
20
21
22

4 combos -> 9 combos, computer over 2x the processing power. Is it because hardware limitations?

Just saw the movie and have a couple questions.

>how is it producing light and heat to make the planets habitable?

And what was up with the ice planet, why were they saying it had no surface?

I think they answer this in the movie, you should pay attention more lol
But I guess the "why a blackhole" problem is simply because there was no other option, since earth was fucked up and light-speed still don't existing in the movie.
The "producing light and heat" is a mistery to me too, but I think that the accretion disc of the blackhole makes sufficient to light it up and make the planets heat, even if they're cold, like that planet where is Matt Damon.

Hey /sci/, i want to play a game with you
I want to see if u can decrypt this message

Rukzlfpd

I encoded it with a vernam cipher. The key is the message with the last letter shifted in the first position. For example, if the message was AbcdE, the key will be EAbcd.
Good luck and have fun

Thanks for the wikipedia search, now I know why Vernam is a cool guy.

But I don't want to solve your message, which is probably just something like "kys"

I remember reading this novel about this guy who got stuck in this endless hallway and he noticed it had a veeery slight curve.

So he took long stick and placed it along the wall(or something to that effect) and calculated the total distance of the circular maze

How do you calculate of a circumference of a circle using a portion of its curve like how that guy did it?

Pretty sure you need the angle of the curve or the radius of the circle as well

I have a solution but it makes a few assumptions.
1. You can measure things, like the stick.
2. You have either the ability to measure angles (perhaps via compass), or the ability to construct an orthogonal line (perhaps via compass and straight edge or using something with a 90 degree angle as a stencil)
3. The stick is completely straight
4. Ability to mark the midpoint of the stick. This may be done by folding the stick, if possible, or compass and straight edge, or just being very careful closing in from both sides of the stick and acknowledging there will be error.

Now. lay the stick down so its two edges touch the wall. Construct an orthogonal line from the midpoint of the stick to the wall. Measure the length of this line, call it x. Then by using the right triangle created in the diagram, we have:

[math](\frac{StickLength}{2})^2+(r-x)^2=r^2[/math]

Since only r is unknown, solve for r by completing the square or using the quadratic formula. Once you have r, just use 2*pi*r
