currently reading this, does anyone know if there's any literature or classified research that studies the real time neurochemical effects of torture/extreme trauma? it's interesting to read about the post effects but I'd love to read about that happens in your mind chemically RIGHT when something awful is happening. I know this kind of research is ethically questionable and in general challenging to accomplish but I have to imagine someone, somewhere has hooked a person up to an MRI machine and made them extremely uncomfortable.
>>7656449
Careful you don't cut yourself on all those edges OP
Bumo, I find this interesting also
>>7656474
it's conceptually fascinating. I'd also love to see an MRI reading of like an extremely high LSD trip. I think that's ethically sound under volunteer assumption and it would produce very similar reactions (being trapped in a machine on a lot of psychedelics would make you freak the FUCK out)
What creatures can survive in a habit which is unusual for them? Can an octopus survive in a swamp?
Humans can survive in space. This one guy has been living there for almost a year now.
>>7656446
>Humans can survive in space
we cant though
we need a pressurized oxygen environment
its more accurate to say humans can survive in zero gravity, albeit with deadly side affects
Pretty much any invasive species does this. They don't just survive, they make the new ecosystem their bitch.
This is the book we use for my Linear Algebra 2 course, and I think it is a terrible terrible book. Most of the Theorems or proofs are given in one or two lines, and many of them are missing proofs (to be done as an exercise). Believe it or not, it is a meme book with the "its trivial" and "the rest is left to the reader as an exercise". fuck no, a book should tell me all the information, then give me chances to apply my learning, not a "fill in the blanks". Also there are no answers for proofs whatsoever, and limited answers on the numerical computation. /rant
>>7656317
also its cover pisses me off with that infinitely extending L
Maths books in general have an annoying incompleteness to them. Stuff like not giving answers to exercises 'so you can't cheat' and the things mentioned in OP can really reduce their usefulness.
haha i also hate this book, i'm glad i downloaded and didn't have to pay the ~$200 CAD at the book store. I imagine it's mostly designed for teachers to base their lectures off of. But yeah, this is one of the worst text books I've encountered
I've learned computations and understand proofs through math.stackexchange for the most part
I can barely understand derivatives and integrals. How far am I from achieving Pure Mathematics?

You should learn some proof by induction

Is plant Neurobiology an actual science?
http://timewheel.net/Video-In-The-Mind-Of-Plants-Documentary
Soon it will be considered by many people, just as psychology.
>>7656027
Eh, its complicated, neurobiology is definitely the wrong word as plants lack anything resembling nerves or brain matter, but its definitely interesting in its own way, its all hormones and chemical messengers and symbiosis with other organisms to a complexity level that is truely impressive. I know of a study that actually took a bacteria discovered in Alaska, which produced anti-biotics and herbicides, exposed it to plant extract, and observed that it ceased to produce herbicide.
In other words, some bacteria...

Yeah it's just botany... but deeeeeep botany
Is the Boltzmann Brain theory babby first discover or is it the end game? The idea that we exist because of a stochastic fluctuation in a higher-entropy universe sounds very appealing to my brain. Am I being deceived by my desire for answers or did Boltzmann discover The Answer for us?

>>7655732
No.
>>7655732
Yes.
>>7655732
Maybe.
How does /sci/ feel about global warming?
http://strawpoll.me/5990216
>>7655702
apparently global warming decreases global intelligence as well, since so many people fall for the climate shills.
>>7655702
Hot and bothered.
>>7655702
My vote was for AGW not happening since I assume that's what you meant.
Damn rising sun messing with my aurora
are u a qt penguin
The sun is a dick. Every morning it tries to blind me while I drive to school.
>>7655691
I wouldn't mind so much. Star gazing is still one of my favourite things to do.
I'm sure we all agree that gene editing is good, ONCE the issues have been sorted out.
But I would like /sci/ to play devils advocate, and speak only on the ethics of the situation.
From an ethical point of view, how can you justify the point of view that, research into gene editing of embryos should not be allowed?
>>7655674
The same reason we don't do human drug testing until after testing on animals. Imagine if the procedure isn't 100%, or something wrong is copied. You've just turned a viable human into a retard.
>>7655674
If we gene edit we will eventually erase the identity of our species and replace ourselves with superior organisms.
Is that really what we want? I would say yes because fuck being biologically mortal. Some ethicsfags will inevitably write misconstrued thesis' on it because they couldn't find a better topic for their shitty philosophy degree though.
>>7655685
>You've just turned a viable human into a retard.
But why is turning one out of literal billions into a retard bad when it could greatly uplift the remaining billions?
IS there a scientific reason why goats are the best animals?

I really think this is not a suitable post for /sci/... Stop flooding the board with shit...

Two breakthroughs in fusion research:
http://www.spacedaily.com/reports/Physicists_uncover_mechanism_that_stabilizes_plasma_within_tokamaks_999.html
http://www.spacedaily.com/reports/Discovery_of_a_new_confinement_state_for_plasma_999.html
So when will we have fusion power? I'm trying to plan for retirement here.
Nuclear physicists here, 10 years for first one, 50 years for commercial
>>7655842
>10 years for first one
less than that m8. FRC plasmas ftw
By the way, when is the Max Planck institute turning on the stellerator?
Could there be a yet-undiscovered super-Earth within our Solar system, out beyond Pluto?
>This Sedna-like object has the most distant perihelion of any known minor planet and the value of its argument of perihelion is close to 0°,” the team writes in their second paper. “This property appears to be shared by almost all known asteroids with semimajor axis greater than 150 au and perihelion greater than 30 au (the extreme trans-Neptunian objects or ETNOs), and this fact has been interpreted as evidence for the existence of a super-Earth at 250 au. In this scenario, a population of stable asteroids may be shepherded by a distant, undiscovered planet larger than the Earth that keeps the value of their argument of perihelion librating around 0° as a result of the Kozai mechanism.”
Even if there is, it's going to be couple of light years away and impossible to reach in our lifetime
>>7655336
If we send a man mission to venture outside our solar system, is it possible to reach 4 light years?
yeah, his corpse will get there
Are jetpacks actually fucking real now? Is the future happening?
https://www.youtube.com/watch?v=gCYSWyHDpfU
>>7655220
Jetpacks have existed for decades. They just have always sucked. They're likely to continue sucking for the foreseeable future.
>>7655220
I don't know why they're claiming it's the "world's only," rocket packs have been around since the late '50s and even the turbine-powered pack has been done before (Jet Pack International has/had a prototype and was trying to bring it to market for quite some time).
Those look like JetCat model jet engines.
Why does butter take less time to solidify in a refridgerator than it does to liquify at room temperature?
You should read about statistical mechanics.
>>7655167
A basic rule of physics is that temperature is related to how fast molecules are moving. In gas state they're highly erratic, solid they're pretty much stationary. Colder temperatures mean the molecules move around less, therefore are more willing to stay in a solid state.
>>7655222
I didnt ask why a refridgerator makes butter solid
Is it worth getting a flu shot? And how can you better protect yourself against a flu?
-Washing hands
-Dress warm
-Avoid proximity near sick people
Anything else?
Dont rub your eyes. The eyes are the biggest entry point for infection.
The flu this season is mild, but lasts long and is very infectious. Its worth getting a shot if you havent already.
Over here in europe only old/sick people get flu shot.
>>7655158
>Is it worth getting a flu shot?
Yes.
>And how can you better protect yourself against a flu?
See above.
