What's a good introductory text or lecture series to get me interested in math again?
The past few years it's seemed like a useless foreign language to me, no doubt because of the half-assed american public school system, and my ever-increasing apathy towards the subject. However, recently I'm starting to see the appeal and really feel I need to build my self back up from the ground level.
what math do you already know?

Try Khan Academy.

I've taken a semester of university Calculus 1 and failed out of a second semester because I had clinically diagnosed depression and assessed it as my least important investment.
>>8733153
Used this a bit in High School. Might as well give it another shot and see if it hits the spot this time.
Does true randomness exists?
ya
can you predict every next sample of noise on an analogue oscilloscope? no you cant. math is dumb lol
>>8733045
couldn't you just plonk a steady voltage in
>>8733045
wtf is your problem, op asked about true randomness and you're over here talking about prediction???

dafuq?

>monkeys and birds
They didn't exist back then you git.
>small organisms with lower caloric demands better able to withstand ecosystem collapse than large resource-intensive organisms
>I just don't get it
of course, mass extinctions are a lot more complicated than that, but that's the primer. remember, it wasn't the meteoroid that killed all those things; it was the collapse of the global food web caused by the scorching of much of the globe and the ensuing impact winter killing off a lot of plant life.

Is "I think therefore I am" invalidated when you consider that we may just be AI in a simulation? Can I not even prove that I exist?
"I think therefore I am" is automatically invalidated because it assumes the existence of an 'I' without ever having proved such an existence, it's just a circular argument. If you're not sure there's an 'I' then you certainly can't start with "I think"
>>8731497
There is no "I" in Descartes's original statement in latin.
hey /sci/entists, I am thinking about writing a paper schools being either good or bad for people with depression or anxiety or if it causes or stops these things from happening, can some of you help?
>>8731450
I'm generally at my least depressed when I'm immersed in an interesting problem.
>>8731450
If you have agoraphobia like me, then school is obviously stressful, scary, and exhausting. But knowing I'll have a piece of paper that makes me far more employable some day actually cures a lot of my hopeless depressing thoughts. Socially failing every day is awful, but it will pay off I guess is what I'm saying.
I use problems that are considered difficult but are easy enough for me that I don't get stressed about them as a method of escapism.
sup /sci/, physics student here looking for summer job Found an internship that looks promising thats for maths students, only issue i I need to have excellent SQL skills. No fucking clue what that is, but gogled it and I'm guessing it's some sort of program/language? In terms of languages I've done modules on C, C++ & Python, and I've also used LabView, Origin, bunch of other programs. I'll have two weeks between finish of exams and start of internship, if I dedicate all that time can I gain 'excellent skill' in this SQL thing?
>>8731357
omg, what kind of shit uni you are at?
>>8731365
I highly doubt unis anywhere would teach you SQL in your physics undergraduate. Thanks for the helpful response though :^)
>>8731357
SQL isn't really a programming language its more to do with manipulating / creating databases. I'm no expert but I think you could get decent at it in 2 full weeks
/sci/, how does one become a mega genius?
>>8731116.
YUO MOST FOLLOW PATH OF GREATS THAT CAME BEFORE YUO.
By creating the state of mind you define as the state of mind of a "mega genius" and sustaining it, but you wouldn't know anything about that because philosophy and spirituality is beyond you.

Why? Why do they do this? It'll drive women away from science, rather than make them want to take part. Or, they'll think it is all memes and easy, take up a bachelors in something hard and last a year at most, very sad.
>>8731056
Then what's the alternative? Scaring all of them off from signing up in the first place? If one curious woman out of 10 manages to stick with a science career, all these campaigns will have succeeded.
Granted, the wage-gap is still pretty damn high, but I'm confident it'll even out as women scientists get recognised for their good work. Hell, we might even be able to just call them 'scientists' and forget about this nonsense.
>saw a free mathematics for computer science textbook posted on hacker news
>full of stuff that looks important
>now I have a textbook full of more stuff I feel like I have to learn or else I'm retarded
I feel so fucking guilty about all the shit I don't know. Yet you go in to a library and there are a million important text books called "Introduction to X" and they're all huge.
And then there's all the practical stuff. And the books to read.

You are a loser OP

lmao nigga u dont need no math
bitch i got like masters and cant do a long division :D

Is mathematics just an extension of philosophy /sci? I'm totally disturbed by that.
Why?
no
most philosophy is not axiomatic at all
>>8730920
mathematics is an extension of philosophy in the sense that it is an advanced version of analytic philosophy, proof of this is that most medieval and ancient mathematical texts pretty much read like analytic philosophy texts today (in that they reason with language, but attempting to be as precise as possible)
Any other Mandlebrot Set explorers here? How deep have you gone? Seen any interesting features?
The Mandelbrot set looks like my scrotum, and I'm not gay, so I won't look at it. Simple as that. You want to be gay? Fine by me, but I'm not going to sin for some popular schmopular science.

Algebraic Geometry is about fully faithful functors Spec and Global sections mapping between the category of finite schemes and the category of commutative rings.
>discuss
did you mean affine schemes you dicklit?
What the fuck those that have to do with geometry
>>8730156
Algebraic geometry is about the interplay between geometry and algebra. You can do geometry and prove stuff about algebra. And you can do algebra and prove stuff about geometry.
For example, a classic result is that every cubic surface has exactly 27 lines.

How can spacetime be 'flat' if we can move around in it in three dimensions? I always thought of the universe as existing within a big sphere and the edges of that sphere are expanding outward, how can that be 'flat'?
The same way a piece of paper is flat if you bend it along a direction. If you try and bend it along two directions (which you can't) it won't be flat no more. The only way to distort the paper is to draw a fat person. The mass will cause the paper to curve and thus gravity will be observed as a residual effect.
>>8730138
Well, it is a bit unintuitive but once you understand why the earth is flat then you can extrapolate that same logic for why the entire universe is flat.
Spacetime isn't flat, it's just conceptualizing 3 dimensional curvature is difficult for many
Do you agree /sci/?
>commercial art and graphic design
>architecture
>useless
Huh?
Yes, but they should probably replace Architecture with 'any History major'
>>8730130
the graphic design labour market is flooded, meaning there are far too many graphic designers than graphic design work.
Architects get paid fuck all to do ridiculous amounts of work. Being an architect sucks, it's a shite degree
Can somebody explain his problem to me?
there's no nice arithmetical theory for the reals
