what is the purpose of capacitors at 5 and 8? sometihng with reduycing the influence of capacitance of conductor?
Been a while since I've done audio stuff.
It's probably just filtering out noise in the ground plane. Audio stuff is sensitive like that.
>>8098916
filtering high frequency perturbations.
I think it's called decoupling capacitor in english
Where can one find an advance copy of the movie Vaxxed, or a digital copy?
I heard it has been shown at a couple of festivals, surely someone booted it.

This is a scientifically valid film, not entertainment
>>8098864
First off, if you wanted to discuss the movie, you could've just created a topic directly aimed at anti-vaxxing, not a sneaky OP, this isn't /tv/
Second of all:
>anti-vaxxer film
>vaccines cause autism
>scientifically valid
lol
I saw that thread yesterday on /tv/, and I wanted to bash my head on my desk from the scientific illiteracy. People claiming vaccines haven't had any effect when...

how do integrate this?

Cos(ax + x) and go from there

I'm interested in the idea of brain plasticity, because I'm a piece of shit and there are a lot of things i want to change about my personality. The way I understand it, performing an action "digs grooves" and creates a habit, so over time confident or disciplined activities change your brain to the point you are a naturally confident or disciplined person. I have a few questions about this:
1) Is my understanding of brain plasticity fundamentally correct, even if it's pop-sci tier?
2) Currently I'm using a lot a of drugs, stimulants and beta...

ask your doctor
>>8098788
Plasticity is basically neurons making new connections with other neurons. Supply and demand can make this happen. Look, what I'm trying to say is you won't find any quick fix to being a piece of shit. Work hard, Study hard and be disciplined. We're all gonna make it bro.
why would i do that when i have the great scientific minds of 4chan?
but seriously there is little chance an ordinary doctor would know anything about this
Is this worth learning? How does one go about learning it and how long would it take?
>>8098767
Don't learn too much of it, but yes, it's a great tool.
It's a shitty language, but it has lots of packages and makes graphing pretty easy once you get used to the awful language conventions.
You should maybe spend <10hours learning basics. Maybe even less. Then pick up the rest as you go.
>>8098767
Horrid language but very large and useful code base.
Worth knowing and using, not really worth creating new things in.
Note that some of the great R stuff there (like most of the nonlinear regression packages) is actually just a wrapping for FORTRAN implementations.
>>8098790
what other languages are better, spss?
how do forces work? we know an electron and a proton attract each other but how does work exactly? what is transmitting that force exactly?
>>8098756
geometry of a field.
>>8098760
Elaborate please
elementary particle is a toroidal vortex of aether. electrons not exists as particles. the electron shell is the outer vortex
ok since we have cloning for animals, why don't scientists clone the food we eat, for an example, a box of mini wheats before it hits shelves, in the factory we clone the entire factory full of mini wheats then give it too the stores, we keep giving the stores cloned food so we can keep a endless supply.
Put the bong down son.

we sort of do this already. Ever notice how bananas don't have any seeds? Well how do bananas without seeds reproduce if they don't have seeds? The answer is we clone em'. We cut off a little bit of a banana tree, and like plant it in some stuff to like make it grow into a new tree man. Every banana tree is like practically identical.

1. If they mention the cross product, ask what to do if considering a 4-dimensional system? (Cross product only works in a limited number of dimensions)
2. If they say a function is continuous ask with respect to what topologies?
3. If they say a sequence converges ask with respect to what topology?

Every time they try to skip a trivial step in a proof, raise your hand and insist they explain it because you don't understand
So, I've a question about astronomy, or quantum mechanics, I guess. Given the incredible size of our own universe, would it even be plausible for there to be theoretical billions of them, with some being exact replicas of our very own?
>>8098234
Yes. This has been recognized for some time now.
>>8098234
There is a probability that you are as you are. It's small but it exists. Call this P(you). The expected amount of you's to exist is the amount of events multiplied by the P(you).
In an infinite universe with an infinite amount of stuff which is clustered in a way that's similar to our local region and the stuff obeys the same rules of physics as our own. Let each cluster of stuff be an event with the possibility of you existing then doing crude math you can see that:
P(you) * #(events) =...

...Why would size be a problem?
I mean what would prevent them to be big?... I don't understand the question here.
> watts of energy per second

Dropped.
>>8098205
Watts [which are a unit] of energy per second
You bunch of idiots don't think this is absurd because you don't even know what watts and potency is.
>>8098216
>which are a unit] of energy
Wrong you faggot. Joule is a unity of energy. Watts is a unity of potency, that is, of energy dissipated in certain amount of time. Joules per second.
I have a question for /sci/
How far away do you think we are from computers being at a point we can create our own universes in them with the detail, scale and AI on the same scale as our own?
Do you think it will ever be possible?
you would need a computer larger than the size of the universe
>>8098192
But what about quantum computers?
I feel like experimenting with all sorts of weird configurations of helicopter blades to see if I can make a 3D printed aircraft as efficient as a frisbee.
What simulator to use?
>>8098132
>as efficient as a frisbee.
frisbees aren't that efficient.
>>8098132
what 3d printer do you have?
>>8098132
>efficient as a frisbee
efficient how?
low fuel use?
aerodynamics?
So I was exploring a superfund site today with some friends. I won't specify which specifically but I'll say that it's one of hundreds in Western NY, (USA). We came across this pit full of an almost glowing blue liquid. The white powdery looking buildup along the bottom makes me conclude that perhaps it's acidic? I was t going to touch and find out. Can anyone here shed light on what I'm looking at? Nothing came up when I tried to research it. Any insight would be greatly appreciated.
>The white powdery looking buildup along the bottom makes me conclude that perhaps it's acidic
please explain how you came to this conclusion
>>8098182
It's a hypothesis more than a conclusion which is why I also threw the word "perhaps" in there. Salicylic acid reacts with organic material that way that's how I came up with it. Then again sulfuric acid turns sugar black so I suppose I can see why it's not a great hypothesis. I'm not a chemist and didn't claim to be. I simply asked if anyone qualified coils identify this liquid/occurrence.
>>8098119
Fucking use Google you faggot.
d/ic/k here.
I came here to ask what science topics should I learn to help me become a better draftmen and painter.
obviously anatomy, but how bout optics and other topics?
I've noticed art education is simplified education for retards where the teachers barely know the topics.
>>8098056
Drawing 3-d structures might be a worthy challenge to help you get better at drawing.
Functions such as u(x,t)=g(x)f(t) may be a good place to start but also accurately drawing relatively simple chemical structures if you're into that sort of thing.
>>8098120
care to give a list of topics to google?
Any preference of the topics given (functions or chemical structures) ? in essence they're the same
How much methane does an adult cow actually have?
Let's say it it ate something and spontaneously combusted from within.
Would the concussive force produced be akin to a grenade and obliterate everything around it? Or would it be like a Dodongo in Zelda and just blow up a little and die?
I'm writing a story.
>>8097998
They are literally Hindenburg waiting to explode.
Technically, and this is from an ultra realistic scientific perspective mind you, cows have the equivalent of 100 tons of TNT or 1/2 the yield of an early atomic bomb packed to an area of about 6 square feet.
This is why farmers never combined traditional plowing with gas plows, due to the fact a simple malfunction could level a Country.
