Can the electrical impulses of a brain be read, interpreted, "monitored", and/or influenced? Can information from the auditory/visual cortex be displayed on a monitor? If so, can it be done on a grand scale?
Asking because my paranoid schizophrenic friend is freaking me out. To the point where I want to know if it is or ever will be possible. I know it's outlandish and dumb as fuck but what isn't nowadays. I'm also asking from the standpoint of "will it ever be possible" more than "is it possible now".
>>8469944
Eventually, absolutely.

>read
yes
>interpreted
maybe
>influenced
Not in a non-invasive way. Yet. Mostly
>Can information from the auditory/visual cortex be displayed on a monitor
yes, but it might not be an image
>If so, can it be done on a grand scale?
yes, everything can be scaled up
btw all of these require huge amounts of equipment right next to your head, so it's not happening to you right now.
>>8469944
Yes and no. Mind reading technology is possible, with some constraints. You can infer the content of thoughts from measuring electrical shit in the brain. E.g. you can infer stuff like "this person is thinking about an elephant right now". However it remains at such an abstract level. The actual image of the elephant cannot be reconstructed, because qualia are fundamentally a quantum process and the collapse of quantum mechanical wave functions is uncontrollable.In particular you cannot enforce a very detailed picture into someone's brain.
What is algebra, really?
sophisticated sandrunes
Ive heard two definitions. probs wrong tho
1. equation solving
2.manipulation of symbols that represent numbers/variables
remember that Greek math had no idea of equations

How is Computer Science a legitimate field of science?
Only pure mathematics is a legitimate field of science.
oh this thread again.
graduate level computer science is pretty legit
undergraduate level computer science is mostly preparing those for a career as a software developer
and yeah, basic algorithms, discrete math, linear algebra, etc... aren't necessarily difficult compared with some of the shit math / physics / engineering bros have to deal with, but they aren't easy either.
>>8468779
dude logic lmao xD
prefacing this with a disclaimer that i do not come from a science/math background.
quantum mechanics are now present in a history of science class. while there will be in no way a testing of technical knowledge or application, i hate the feeling of sitting in lecture and not knowing whats going on beyond pictorial or illustrative examples.
im looking for some material that will teach me about it while hopefully introducing some of the mathematical concepts involved. i understand that me trying to understand this in this sense is like trying to speak a foreign language without practice but im still curious and diligent enough to try.
i checked the pinned post and couldnt find anything per se.
any help? pic related?
it would be basically pure complex math from your point of view. of course you can just read/watch wrong simplified pop-scientific bullshit but you don't want that.
How far does your understanding of math and physics go?
>>8468766
impoverished. classical mechanics, a rough understanding of relativity (spec/gen). mathematics even less so....
i feel like im in a terrible inbetween, not wanting to settle for the pop-sci stuff but also not trained to understand on a technical level.
>>8468776
wait if you actually understand the theoretical physics of classical mechanics you can definitely look into quantum mechanics.
all you need is wave functions.
>topology
can you PLEASE explain to me why this masturbation math exists?
To give your stupid-ass [math]\lim_{x \,\rightarrow\, a} f \left( x \right)[/math] a meaning.
>>8468683
What a fucking fag. Abstract topology is useful in robotics.
>>8468691
the definition of a limit never needed homoemorphic dick sucking
One of my tard classes caught up with me and now I have to spend an entire day writing an essay about racism or some shit. Why are general ed classes so fagged?
I'm general edding about history of energies and it's pretty based
>>8468675
>hate thread
This doesn't belong on /sci/.
>>8468680
Why? It's stem students fuming about non-stem classes. /sci/ is more about the lifestyle of scientists and mathematicians than actual math and science.
How do I combat brain fog/ spaceyness? All this semester I've felt out of it and not all there, and keep overlooking and forgetting things and making dumb mistakes that I should know. Physically I feel slightly lightheaded and like I've taken a small hit of weed and had a drink or two, like I just woke up but all day long. Is this stress? Caffeine doesn't really help.z
For how long do you use your computer for entertainment?

Does a deep undersea cable have any impact on the power required to transport electricity (due to pressure) or is it not affected at all since it's just the flow of electrons inside the insulated material?
I don't want to hear about fibre optic. I'm talking about electrical cables carrying a flow of electricity between the sea floor and the surface.
I wouldn't suppose any significant effect, then again, my understanding is from a mechanical engineering education.
>>8467726
High pressure influence on conductive coefficients of paramagnetic materials is about what I think you're interested in, there son.
Off hand, I dunno if impedance, resistance, resistivity, the skin effect, and so on are influenced by high ambient pressure.
>>8467726
>flow of electrons
you mean the flow of electric charge?

What's it like to study mechanical engineering?
>studying mech engineering
>thermo lab
>refrigeration cycle experiment
>have to write lab report
>know R12 is in two phase region after throttling
>temperature and pressure indicate it is subcooled
>ask technician
>yeah.....some R22 was mixed in there a couple years ago, just assume pure R12
How the fuck am I supposed to write a goddamn report? The calculations are all fucked up.
boring as fuck
so i switched majors
>>8458886
I keep hearing this from people. That Mech-E is boring and does not correlate to the actual job market in theory or practice.
What then is the preferable degree? Mechatronics? Manufacturing Engineering? Computer Science?
