Hey /sci/, first post here.
Long story short: I'm a Mexican looking for advice from the ambassadors of science. I'm 25 and got the equivalent of a Bachelor on Trade from Mexico (licenciatura), but I'm trying to get into science; math and physics to be specific.
But I'm not interested in my country's education. math wasn't that appealing throughout my education, needless to say that math for my degree wasn't that interesting,
I won't attend to a college to study as economy is shit around here and I can't afford the time to attend to one.
I need you guys to guide me into science from the best educational models/methods. I just need to know what topics I must study and the order to do so for better understanding.
I remember algebra, but the algebra that is taught in Mexico's public education is rather elementary.
Can you guys help a brother¿ I just need to get into the right track, insted of wandering around hundreds of topics in no particular order.
Thanks.

Depends on what subject you desire to study. Science is incredibly vast. For a first pass maybe go through some highschool textbooks on Chemistry, Biology, Psychology, Physics, etc..
Khan academy.
>>8281137
Im trying to get into math and physics. I know there are a lot of it to study, but let's say I should start from college math; maybe even highschool, I dunno.
I'm taking MIT lectures through OCW, but only Computer Science. Next step is pure math courses, but I'm by no means at that level.
/sci/, is the Big Bang Theory just meme? Do you guys think some other theories, whilst being less know of course, could be more accurate and true?
>>8281132
>some other theories
You are, of course, going to share some of these other theories with us, right?
>>8281140
Sorry I wasn't clear, I was asking if anyone simply knew of any other theories and thought they were better.
Nothing like creationism of course.
>>8281151
They're all very much like Creationism. All.

What did he mean by this?
He fucked your mom or that you need to open up more to your classmates idk. I got one of these handshakes once I still think about it.

take it as a compliment and move on, you better work hard because you clearly have the material to make it worth it
>>8281095
He's seen me on multiple occasions talking to the girls in the class. I just don't talk much in class
Are polymath a generally more intelligent than people who specialize in one field or are they just more curious about knowledge is someone like. Von Neumann smarter than say Einstein or Godel who made deep impacting results but ere specialized in their fields
>>8280983
actually Einstein pops up nearly everywhere in physics, he's the fucking Gauss of physics
I think the question is meaningless. What is "being smarter" even measuring here?
What is the endgame here?
>>8281008
Wasn't Einstein completely ignorant of quantum mechanics

Is dying of old age fully dependant on my bodily functions shutting down?
Just how long could I live if my brain was in a jar and all of my bodily functions would be done by a machine that never loses its erficiency and energy? Would I still die around the age of 80 like the average person in the west or could I live far longer?
>>8280672
Well, your brain is organic just like everything else in your body, so I guess eventually it would give up, too.
But usually death by old age is due to failure of other organs. You might live a bit longer. Chances are you would still be affected by the same brain diseases/mental issues that normally come with old age, though.
>>8280672
Look you stupid shit.
You're gonna get old and die. We all do. Doesn't matter if you make another 5000 threads about it.
You are going to die old and miserable and nothing can change that.
Have a nice day ;)
>>8280694
This.
Don't be afraid anon. Death is just like another puberty. You're morphing into your final form.
Does science know yet how exactly self-control works and how to improve it?
Like how exactly differs the brain activity of a person with high self-control vs low self-control in a tempting situation or where you need to focus despite discomfort. Is there a proven way already to improve self-control?
>>8280611
List everything science "knows", put it in a time capsule for 100 years, open it and watch everybody laugh their asses off.

Posts like these make me wonder whether the poster is underage or literally retarded. I guess we'll never know.

What is the purpose of your post?
Is a random pattern not following any pattern, actually a pattern?
Is random number generator actually creating numbers in a pattern but we cant see it cuz its to o big?
random number generation is not possible in a deterministic universe
>b-but muh quantum ph-
let me stop you right there. we merely lack the technology to understand and predict the movement of quantum particles, that does not make them random. the universe is deterministic, not probabilistic
>>8280594
a number is not proveable to be random
>Is random number generator actually creating numbers in a pattern but we cant see it cuz its to o big?
yes

I just read in the news NASA finished building his rocket and already tested the engines to send humans to Mars.
What do you think about this mission in general?
I thought humanity wouldn´t step another planet until 2050+, but I am very surprised it could happen during the 2020's
It'll be later than that by a little bit. Right now the plan is a lunar flyby between 2021-2023 and then the asteroid redirect mission in 2026.
Nothing planned after that yet
>>8280493
spacex supposedly wants to get the first humans on mars by 2025. nasa astronauts will probably be the ones going. sls is a shit show.
>>8281464
>sls is a shit show
correction: SLS is a way to keep paying pet contractors with the promise of a possible maybe sometime in the somewhat near future trip to Mars.
If science is so smart why can't he predict what my brain will think next?
free will makes your thoughts unpredictable
We already know what you think next ;)
>>8280472
because they don't care.
global warming is a fact and we really can't do anything about it without fucking our lives up even more or developing miracle technologies. no solar panels will not meet our needs. i say we just ride it out, closing industry will be worse sooner than the effects of global warming. in either event we're fucked but allowing industry to work delays the inevitable.nwhat environmentalists want will just make things shitty sooner.
>>8280415
>just ride it out
Thanks for your input, we'll make sure it gets brought up at the next meeting.
why not send all the heat to space ? ;)

Is there any scientific evidence for it? Do they know why it happens?
>IF it is real, then why hasn't it happened, even once, in the last 25 years?
what is spontaneous cumbustion ?
>>8280351
its when people just catch fire from inside their body and basically disintegrate

>>8280349
No.
There's an ignition source and their clothing acts as a wick for their fat so they burn long and hot. It requires special circumstances obviously.
So doing a the 4x4x4 cube for the first time got this far on my own, but racking my brain on this resault and wonder if anyone could help me out
>>8280297
you've bricked it you tool. it cant be solved like that. switch those wrong pieces around, scramble it and try again
I've never done a 4x4x4, but I believe what you have here is a "parity error". It arises when you solve the centers and try to solve the rest as a 3x3x3. I'm sorry, but I don't know the remedy to this.
I "learned" to do this on my own a long long time ago. I don't count it though because I would get parity errors like this (there's another one that is really easy and way more intuitive to fix) and then rescramble and resolve until the error doesn't show up. I eventually googled how to fix the parity and just memorized that. Now I don't remember how it's done. Maybe try taking out the "correct" yellow/blue edge and putting it (upside down) where the "incorrect" orange/blue edge is using the other bad edge pair as a placeholder.
Hey /sci/, so I've been wondering, since axioms by definition are unprovable, do we assume that simple things such as 2 + 2 = 4 are true because such things have useful applications in reality (since 2 + 2 does indeed equal 4)? Like, couldn't we potentially base a mathematics around axioms like 2 + 2 = 5?
>>8280248
You can always define some addition operator, say +', so that 2 +' 2 = 5.
However, to make this operator interesting and analyzable, you would need to define it for all real or complex numbers and see what properties it has. Depending on how you do this, you can figure out whether or not you can define some form of Euclidean geometry with these numbers, etc.
>>8280254
So essentially, you could do this but it wouldn't be very interesting because it probably wouldn't be consistent?
>>8280263
Maybe it would be consistent; I invite you to make the attempt. The requirement that 2 +' 2 = 5 is not a stringent one, it just depends on how you extend that feature to everything else. A positive indicator is if your new definition of addition and multiplication, acting on the real numbers, forms a vector space.
