I took a photo of this structure on top of a hill near a volcanic valley in Japan. Does it look like a seismometer or just a radio tower?
Was it really hot or did you just have a crappy camera
>>7797268
I'm using 30x zoom with a compact camera in that shot.
>>7797265
That's a radio tower. Seismometers are small.
Jesus fuck, /sci/. I just woke up from a terrifying nightmare. The worst part is that I have had it before. And the worst part about that is that the last time I had it was two years ago and was far removed from my conscious mind.
Anybody know if it's normal to have dreams years down the line even though you've completely forgotten it? Like, this I'm genuinely curious if this is a thing that happens to other people to this extent and why.
Whats the dream ?

Me and my parents go to a funeral home in the middle of a cemetery. My dad is going there to get some sort of a medical check up for some reason and there's a burn victim writhing in pain on the autopsy table my dad's going to be lying on.
Afterwards, I end up alone in the cemetery with this man following me. I know he's there, but when I look he'll be somewhere else. The entire experience is fucking horrifying and I'm not about to try and fall back asleep now.

Well, pushing the dream will only makes it come back. Confrontation is the solution. If you don't freak out and let the dream play out, the mind can get rid of it. As long as you can't it keeps it in its subconscious.
Who else here has trouble going to sleep because of thinking about what they learned in math/physics in school today and its different implications/applications. It seems like I get way to excited and end up only sleeping for 4 hours/night. Why is this?
*too. shit sry
>>7797117
It happens to me as well. Tey going to sleep earlier and excercise a hour during the day.
Maybe try not studying after 19
Nice thinly veiled humblebrag circlejerk thread OP.
Hello /sci/,
Is the bottom one wrong, if, so, why?
>>7797099
aufubau diagrams are aweful.
>>7797105
In one, the silicon is hybridized, in the other, it's one of the oxygen, i want to know if both are possible in nature.
A tiny bump

Hey guys, I just for the life of me can't figure out how to find the Voltage across A to B. I found the equivalent resistance, but I have no freaking clue how to get the Vab...

Stopped reading.
There are more than likely very legitimate arguments against having Nuclear power plants in California, but Im not grinding through the ore to find the gems here OP either present some key points or fuck off.
Hey /sci/.
Im awful at math. Or rather, I have terrible math anxiety and I guess what you would call "technique."
To me, I see math as steps to solve a problem;
Step A, then B, and so on and so fourth.
Thing is, I mess these steps up.
Im currently learning Quadratic Functions. Specifically, "Completing th Square" and "Vertex Form."
Math stresses me out, and it ruins my day due to my inability to use proper form while solving problems.
I really need advice. I don't want to be put into an easier class. Please help...
Comment too long. Click here to view the full text.
Are you self teaching or is your professor just that bad?
>>7796991
1. Stop blaming "math anxiety."
2. Solve more exercises
It's not hard.
Or rather, the method of understanding something isn't hard. Sometimes understanding is difficult, but that just means you need to do more work.
Are you having trouble understanding the concept or do you just forget how to do something and make errors? Open up an algebra textbook and read the book's method of solving or go to khamacademy and hear sal's lucious voice. Learning it from something else can be helpful in understanding a topic. If it's practice you need, download some worksheets or find more practice from your teacher.

You're gonna fail OP. The shear fact that you're posting on 4chan instead of studying makes you an idiot who dressed deserves to fail.

yea no you turbo pleb
People say that sexual interaction with people below a certain age damages them (not talking about hymens).
Where's the scientific evidence?
I have a cousin that got raped as a child, she got mentally damaged.
It's traumatic as fuck.
Go back to /b/
>>7796913
People say a lot of bullshit for which there is no evidence, get used to it.
Taking a logic course this semester, using this textbook. Any other reference books I should check out or is this sufficient?
textbook general i guess as well
>>7796606
Off top of my mind,
Hirst & Hirst
Boolos
Simpson
Mendelson
>>7796630
Seconding Simpson.
The Logic Book isn't bad either.
Anyone see any holes in this proof?
Question:
>25 points are chosen inside a regular hexagon of side length 10 furlongs.
>Prove that some number of them are at most 5 furlongs apart, and state the number.
cited proof: http://arxiv.org/abs/1009.4322
>>7796510
>furlongs
P good bait op
>>7796515
it was just a quirk of the question. I copied it verbatim.
obviously the units dont matter
bump please
What is the current understanding of how the lunar maria come to be (the dark patches on the Moon)? Why is it there and where did it come from? Bonus points: Why doesn't the far side have much maria?
Is this a trole
>>7796027
No, just curious how we understand the origin of the lunar maria. I mean, it's basically dried-up lava but there are no volcanoes on the Moon. So how did it get to the surface? It's a lunar mystery.
>>7796233
So, no body here studies the Moon apparently. Interesting.
Why do we have subjective conscious experience? And how does the brain create it?
through quantum elevators
>>7795144
You wouldn't ask that question if you weren't conscious, so that's a senseless question family
Hard problem of consciousness can't be solved by science
