I still don't get it. Why doesn't the electron fly into the proton?
>>8960061
Boundary conditions for the wave function of the electron. That is what gives rise to quantization.
>>8960061
Well classically it's understood as the Coulomb attraction and centripetal force being equal.
But that's classical, the modern understanding is that the electron has no definite position before measurement. On measurement the distribution of positions collapses to a single definite position, on average this position will be the Bohr radius. However there's a small, but non-zero, probability of it being found inside the radius of the proton.

Honestly, will technological singularity ever happen in our lifetime? I am afraid of islam take over the world first than the machines.
Neither is happening.

>I am afraid of islam take over the world first than the machines.
>Islam does not take over the world
Then women in western countries keep getting more political and economic power, on top of their huge social and sexual power, and then start a dark age where men are executed on the streets for disobeying and all men must be sterilized and live as livestock.
>Islam takes over the world
Women lose all of their power, even their sexual power as they have to cover everything. Men keep enjoying cold ones with the boys forever.
I have already made my choice.
>>8972122
Kurzweil just rescheduled the singularity from 2030 to 2045.
why are there no rival species to humans?
How do you know there isn't?

We killed and ate them.
I'm told there's some sort of physics thing that makes this happen, but I didn't understand it.
It's a worm, right?
If I am correct then it appears to be an Ebola

Does my cat have a conscience? How intelligent are cats?
(Experience with cats solving the most difficult problems highly required).
Please tell me my cat is intelligent, he is a Sacred Cat of Burma like the one in photo.
Does your cat show signs of regrets when it has done something it knows it shouldn't have?
>>8971999
Obviously never owned a cat.
>>8971992
What subfield of math is it in?
Why don't you use safe nootropics like kratom?
"white vein" kratom is used for the nootropic effects as the other strains often cause an unwanted high.
It lasts for quite a bit and it isn't too powerful.
pic related is white vein kratom
>>8971822
what the fuck.
I swear that this plant was grown all over the place in my old school in South East Asia.
>>8971840
it's often harvested in south east Asia so it might be it
did you see anyone taking it?
>>8971822
Kratom isn't a nootropic you fucking junkie.
Can someone explain the question of free will to me in a way that's not totally vacuous?
What I've heard is that if there is free will, then people can make decisions. In other words, that there are possibilities/ways the world could have been had they made different decisions.
But as far as I'm aware we are 100% incapable of observing other possible worlds, regardless of whether or not they exist. So the question of free will is fundamentally undecidable, and hence pointless.
>>8971642
Wrong.
There are many systems we can model behavior for all time. It may or may not be possible for us to determine the evolution of the universe on a small scale so that we can predict how everything acts. Then, that means we have no free will because our actions and existence were set into motion at the start of time.
At the moment, it is undecidable but it is answerable
>>8971642
seems like we're just along for the ride desu
>>8971706
So what is the observable difference between a world with free will and one without one? The existence of something that models the universe?
Realistically speaking, what would a city under the sea cost? Not sure if this is where I should post this but I've been replaying Bioshock.
Assuming construction would start this year using technology we currently have. Windows and aesthetics would be an absolute necessity, like Ryan said, we ain't building no tub.
a lot
>>8971559
I guess I didn't mean a specific number but it would have to be in the trillions at least, right?
>>8971580
how deep would you want to go. And it would likely be in the nature of 10's of of billions.
If you want said city to self sustain with its own agragarian section and industrial portion, in the 100's of billions.
How safe is lunar soil to eat? Would eating it be any more harmful than eating regular regolith?
>>8971184
the fuck would you eat soil ?
>>8971190
Africans eat soil. Even when they live in Europe they still eat soil.
http://www.bbc.com/future/story/20160615-the-people-who-cant-stop-eating-dirt
>>8971190
Remember, science isn't about the "why". Plus, soil is a bit of a misnomer. "Lunar soil" isn't really soil, it's regolith.

Why do we have to sleep? Do some animals don't sleep?
Do bacterias sleep?
>>8970536
It's actually pretty amazing that we still don't know for sure. I mean we spend about a third of our lives with it, but we don't really know why.
Anyway, it seems obvious that it has to do with brain function, considering what happens when we don't do it enough. Also, I think everybody made the experience to some degree that sleep helped reinforce whatever we learned or getting over emotional trauma. Children sleep more than adults, which probably has to do with increased neural plasticity. So it kind of seems plausible that during sleep there is some sort of maintenance going on in our heads. If I think about neural networks in computer science, I can imagine hat there's some kind of gradient descent thing going on in our heads.
>>8970543
I would just add that it's also probably beneficial for some metabolic functions unrelated to brain.
Unspent energy saved from not moving around can be used elsewhere.
Are virus living organism?
Why are there virus in the space, how do they survive?
Since when do virus exist?
How did they evolve?
Where can't virus survive?
Are some living species immunized?
...
https://en.wikipedia.org/wiki/Virus
They probably came from bacteria-like organisms, that showed parasite like "behavior". After some time they became totally dependent of other cells.
Some scientist think they come from rogue DNA strings i belief
>Are virus living organism?
No. They don't have their own metabolism
Why are there virus in the space, how do they survive?
Lots of viruses have envelopes, much like bubble wrap around an expensive vase. Some have clever lifecycle where they never ever see outside
Since when do virus exist?
Hard to guess.
How did they evolve?
I think some were likely retrotransposon-like strands of DNA that acquired an envelope. They likely all don't descend from one single virus. Not much is known about this
Where can't virus survive?
They're pretty frail. Not many places outside their hosts or vectors unless they're enveloped.
Are some living species immunized?
Yes. Though you have to kill the already infected cells rather than the virus copies alone.

You faggots studying diligently for your MCAT? No, you're here, your dick is in your hand, and you've got loli and furry porn in 31 other tabs. Pay attention; I'm gonna help you. If this gets enough attention, I'll make it a thing. You ready? Let's do this.
The nervous system has two primary divisions: the central and peripheral nervous systems. (pic related) The CNS is comprised of the brain and spinal cord, while the PNS (hehe) is comprised of nerve tissues and shit OUTSIDE the brain and spinal cord. This includes 10 out of 12 pairs of cranial nerves (the optic and olfactory nerves are outgrowths of the CNS; we’ll cover that shit in future posts) and all 31 pairs of spinal nerves. Sensory, or AFFERENT neurons, send sensory info from receptors to the CNS. Motor, or EFFERENT neurons, send motor info from the CNS to your muscles and glands. There’s also a third type, interneurons, which are found between other neurons and are numerous as shit. (MNEMONIC: Afferent neurons ASCEND to the CNS, and efferent neurons EXIT to the rest of your body.)
>>8969710
The PNS (hehe) has 2 subdivisions: the somatic and autonomic nervous systems. The somatic nervous system is comprised of sensory and motor neurons scattered across your skin, nerves, joints, and muscles (like you have any, fag).
The autonomic nervous system (ANS) controls the muscles you’re not conscious of-the ones that regulate digestion, heartbeat, breathing, glandular secretions, etc. The automatic shit. That’s a good way to remember it, actually. “Autonomic” and “automatic” both share the root word “autos,” meaning “self,” which is why you’re fucking autistic.
Now, the ANS has further subdivisions: the sympathetic and parasympathetic nervous systems. Think your puny brain can handle all this? These two are antagonistic, meaning that they work against one another. For example, the sympathetic nervous system would amp up your heart rate and relax your bronchi, while the parasympathetic one would slow down your heart and constrict the bronchi.
>>8969714
The parasympathetic nervous system is there to conserve energy, and as such, it’s associated with rest and sleeping. You probably use this one more. It also acts to stimulate peristalsis in digestion and exocrine secretions. “Rest-and-digest,” basically. It:
>constricts your pupils
>stimulates saliva (you drooling retard)
>stimulates bile release
>contracts your bladder
>stimulates peristalsis and secretion
>constricts bronchi
>slows your heart
The sympathetic nervous system, on the other hand, is brought into play by stress. You know the phrase “fight or flight?” That shit. It:
>dilates pupils
>inhibits salivation (you should use it more)
>inhibits bladder contraction
>relaxes dem bronchi
>ramps up your heart rate
>inhibits peristalsis and secretion
>stimulates sweating and piloerection (no, not “pillow erection; that’s your dakimakura)
>stimulates glucose release and production
>stimulates orgasm (hey, maybe you do use this one)
>stimulates secretion of adrenaline and noradrenaline
>>8969716
The brain is covered with this thick sheath of connective tissue called "meninges." This shit keeps the brain anchored in the skull, reabsorb cerebrospinal fluid, and generally protect that brain of yours. There's three layers to them: the dura mater, the aranchnoid mater, and the pia mater. Cerebrospinal fluid is the solution inside which the brain and spinal cord rest, and it's produced in little cavities called "ventricles" inside the brain.
If there are goggles that let colorblind people see color, is there something similar to let people see colors humans in general can't see normally?
