Who is at the forefront of the development of AI? Soon finished my master's degree, and so I want to dedicate my whole life to science, I would like to get the PhD where I will work or nearby. I am now considering the option of German, TUM, but it is worth to have a fallback.
>>7646100
The forefront is at Google Deepmind. They are in London.
I don't know if you'll get there though: they're hiring, but you basically need to be a genius to get in.
>>7646150
I don`t want to work with Google or Facebook.
>>7646150
IBM or Google. Watson, Deepmind and BostonDynamics all look promising.
I came up with this and want to prove it but I dont know how, any idea?
>>7646074
Wouldn't it just be how you came up with it worked backward?
[eqn]3 \sum_{x=0}^y 3^x = \sum_{x=1}^{y+1} 3^x = \sum_{x=0}^y 3^x + 3^{y+1} -1[/eqn]
Therefore
[eqn] 2 \sum_{x = 0}^y 3^x = 3^{y+1}-1[/eqn]
>[math]y \in \mathbb{N}[/math]
>[math]y > 0[/math]
why...
Anyone else get anxiety looking at pictures of large planets/space? I don't have a fear of heights but this stuff is really spooky to me.
ITT post space.
>>7646047
what a pussy faggot you are
"ooooh I get anxiety looking at space because big and we small xd"
fuck off, you should have posted this in a cringe thread
>>7646047
Me too. It's just so creepy, a massive ball hanging in nothing. Uranus is creepiest. So featureless, just sitting there. "WHAT DO YOU WANT????"
"Uranus"
:S
Is talent/genius derived from nature or nurture?
Einstein was a genius. He had three children who shared 50% of the same DNA as Einstein himself. Two lived fairly mediocre lives. One became a successful professor. One became mentally ill. His parents were also nothing spectacular. So much for the "nature" theory then...
But as a social experiment, the Polgar sisters were trained from birth to be excellent chess players precisely in order to test the nature vs. nurture theory. It worked, and one of them became the 1st ranked female chess player in the...

Having good genes in terms of intelligence is certainly a good head start. You can't expect someone with below average intelligence to excel in and massively contribute to any scientific field. So being born with good genes is certainly a precursor for success. It is however not a guarantee for success. If you don't work hard or live in poor conditions you will still just be a burger flipper with good genes. So both nature and nurture play a role in this, not the one or the other, but both.

This IS happening today, just look at all these people on 4chan, we now have so many gifted senpai s that with some time we may get close to solve the hardest questions

This I agree with. As someone who has met people with moderate special needs before, I can safely say that someone with an IQ of 60 and has Downs syndrome isn't going to win a Nobel prize in the sciences, discover the cure for cancer, or solve a Millennium prize problem no matter how motivated they are.

What is the purpose of sleep? It's not like we get energy from it or anything.
>>7645962
it's to prevent you're braine from overeating
>>7645962
We used to not have light at night. Electricity is a recent thing, you know. Our consiousness couldn't function after the sunt went dow, due to the lack stimulae.
Do you think it is possible to invest something that would allow a human to not ever need to sleep?
What are some comfy YouTube channels for science-related topics? I have a small science background (undergrad in psychology >psychology is science) but just enjoy learning and like to fall asleep to YT videos.
you could watch lecture videos i guess
>>7645827
any good sources? (besides the obvious like ted)
bonus points if psychology related because I'm studying computer engineering in the context of psychology
>>7645831
MIT, Yale, and Stanford have good channels with playlists of lectures. i don't know how many pertain to psychology but if you search a particular sub-field i'm sure a lecture video will show up
I'm no physicist, but there's been some confusing claims made about this thing.
Some are calling is it a perpetual motion/free energy machine. It's not is it?
Some are calling it a warp drive. It's not is it?
As far as I can tell, the main claim is that it produces thrust contrary to conservation of momentum, and there is no good account of how. But why hasn't it been written up yet? I'm reminded of the cold fusion blunder.
>>7645727
Ah German Weiner pump
>>7645727
>free energy
not nearly efficient enough for that.
>warp drive
some space warp has been detected but very little.
It's just a better thruster in space that can run forever.
>>7646335
Doesn't reactionless thrust imply free energy?

> Could there be aliens around the star KIC 8462852? You may either be relieved or disappointed to find out that the Allen Telescope Array scanned the star for evidence of advanced civilizations, and has come up empty.
Dyson Spherers BTFO. Accept that there are no ayyliens and move on.

>This rules out omnidirectional transmitters of approximately 100 times today’s total terrestrial energy usage in the case of the narrowband signals, and 10 million times that usage for broadband emissions.
Pardon me if I'm not convinced this is anything but the weakest constraint on the presence or absence of ayylmaos.
>>7645643
it isn't. If they were signaling anything on a channel, we would have caught a glimpse of it. But we didn't. Because it's not aliens. It's never aliens.
So I saw this space time/gravity visualized shit and thought it was pretty neat. It's basically the universe as a 2D plane and when matter is present, it pushes down on it and makes other matter revolve around it (to describe gravity). I then realized that the theory of this was using gravity to describe gravity itself.
So, is this okay or not for it? Does that deem the theory false? Correct me if I'm wrong.
>>7645569
It's just a representation of an idea, stop reading into it too much.
its taking the concept of mass in the 4-dimension effecting the 3rd dimension, but taking it down a knotch so humans can understand
so mass in the third dimension warps the second dimension, just how mass in the fourth dimension warps our percieved third dimension
>>7645569
No it doesn't. It's saying that objects move in straight lines along the curved spacetime. The curve in spacetime is gravity, it is not caused by gravity.

I genuinely don't understand how this works. It makes no intuitive sense to me.
If I'd look at this I'd think you'd have to pull 100N since you not only have to lift the weight but also got friction on the rolling parts.
Someone explain this magic to me. I'm a fucking retard.
>>7645552
more than 100N*
>>7645552
Anything with numbers like this doesn't include friction. The weight is split in half. 50 going to the ceiling through the purple part of the pulley, and the other 50 going to the long part of the rope. All the pulley does is change the direction of the force. It changes the red 50 so that it pulls up on the weight
the top pulley is weight bearing hth
Is /sci/ smarter then the average Facebook user
>>7645531
It can't be simplified any further.
9^(8x^2) bruh
9^(8x)^2
/sci/ how is this clear? I don't think it is clear.
This is mathematics.
Clear means get your paper, get your pen, and after some writing, you'll see its true. Clear does not mean it should be immediately obvious to you just by looking at it.
>>7645412
Um, duh?
That circled part is fucking basic algebra.
What is division?
>>7645341
The ratio of one object and another in a common basis
>>7645343
Is it the most complex of arithmetic operations?
>>7645347
No, it is an extension of multiplication, in the same way subtraction is the addition of negative numbers (addition of inverse quantities), division is multiplication by inverse quantities.
write something in normal sized hand writing and send it back to the past to change the scientific development.
what do you write and who do you send it to?

im a nihilist does it look like i give a fuck lol?

I'd give it to Einstein while he was still a young man.
Cosmology noob here.
Since we have observable and documented evidence that galaxies, including our own, are rapidly moving away from each other, has there been any attempt by scientists to plot the exact location in 3-dimensional space where the "big bang" actually occurred?
>>7645278
Since every galaxy is moving away from every other galaxy, the only realistic answer to "where did the big bang happen" is where ever you are observing from.
>>7645278
I suppose it's possible, but why?
There's no real reason to figure that out.
I imagine the computing power required would alone make the task nigh impossible.
>>7645278
Everywhere. It's not an explosion, its a rapidly expanding point.
Your question is like blowing up a balloon and asking "what us the exact location of the balloon when it was less inflated?
