I feel like if everyone on /sci/ watched this, half the threads wouldn't exist anymore.
It always references papers to back the claims and explanations.

if you want your mind blown every time, just watch their Relativity playlist.
Every video starts with things everybody knows and builds up to amazing stuff.

I've been an arse and left studying very last minute for a fluid mechanics exam. Pic related are the topics that appeared in the past four years, and I have attached the past papers in question.
Is it at all possible that I can pass this exam I have in under 24 hours time? Does anyone know of any good guides or videos I could use? Any help at all.
I need to get 47% in the exam to pass.

So, since /sci/ is my main board, but I´m (honestly speaking) a brainlet, let´s have a thread about geology, especially about collecting minerals and gems.
So tell me what do you have, what do you want to get and so on. I´m very interested.

Hey /sci/
How do I get better at math? I mean really better. How do I develop an intuition and make connections to solving problems I haven't seen before?
I'm in calculus 1 and I'm struggling a little. I'm an older student, I didn't take math for a long time, but I decided to go back to school and major in it. I took a pre-cal class after almost 8 years of not studying math and did fine. Got an A.
I can plug and chug just fine. I can crush problem sets. I attend the lectures, I understand what's happening in lectures and after some initial struggle, I do fine on the homework.
But I struggle in new situations. My algebra and trigonometry is weak and it's holding me back. But I like math, I really do. How do I get better? I want to be better.

I'm currently in my first year of college ill be majoring in astrophysics. Where can i get an entry level job that is at least somewhat related to my field?

museum/planetarium jobs are extremely competitive due to the fact that universities pump out far more physics/astrophysics majors than are jobs created by the market
your best bet (and it's not a very good bet) is to go for grad school & pray you get into a good grad school, complete a phd & pray your phd is compelling/interesting, apply for post-doc positions & pray you actually get accepted/get accepted into another distinct good school, apply for tenure track jobs & pray you get one
note that schools also pump out far more phd graduates than empty professor spots per year
to be honest, if you're concerned enough about career paths then your best bet is to go into engineering and study astrophysics recreationally either simultaneously or after you're done your degree
>>
>>8082332
The fact that having a PhD has become less and less powerful over the last century, to the point where it's highly unlikely you'll get a tenure position, is largely due to the relaxation of admission standards at the undergraduate level. Applicants are getting lower quality each year, class sizes are increasing, and yet professor positions remain largely the same number.
Alternatively, if you do work in some physics related field that employs advanced & interesting numerical methods then there's a possible career path in quantitative finance/investment banking for you.

Hi I wanted to know am I schrizophrenic?
I rarely, but see hallucinations like I might get noodles confused with intestines and get shocked, see things like flying snakes outside my house it but feels like a dream like its not real and happens for a split second, it doesn't bother me though.
However might 'feel' it like if I imagined if something was on my shoulder I'd kinda feel uncofortable.
My thoughts get muddled up and are constant they feel like a different me. Same with my body moving sometimes.
My speech is random and might spout gibberish while knowing I'm spouting gibberish
My perception of reality might change like I might see everything like a gut/entrail like substance (like inside your body) and start laughing like I'm enjoying it.
Sometimes when I'm sick or tired my thought go haywire and my thinking goes to a point I cannot well explain in english what I think, its like these thoughts cannot be explained or understood when I am sane.

4chan really shouldn't be the place for you to ask this, but this seems like symptoms of schrizophrenia anon, you need medical care ASAP before things get worse.

DO NOT DO THIS. They give you pills that make you dumb and make your moth dry, and you have to tell your employers and such that you're a schizophrenic. It's much better just to keep it a secret.

Earlier I devised a deceptively simple-seeming maths problem. To my annoyance I can't solve it:
You want to cut a circular cake, diameter d, into x pieces of equal area.
The traditional way of doing this would be to cut normal slices every 360/x deg around the circle.
However you are an autist from 4chan and need each slice to have the exact same area - you also only have a ruler to hand.
Therefore devise an equation/ set of equations to cut the cake in parallel slices into slices of exactly equal area simply in terms of x and d.
Please note, this is NOT a homework request and I will be pissed off if anybody suggests it is, I devised this problem and I think it leads to a procedure not an equation but am really not sure - if you can begin to understand it you will hopefully see that it is at a level of maths higher than one at which you might be given "homework", thank you

If you're a masochist or a Sith Lord, I doubt you will like going into chemistry, unless you were a zealot about it..
But the mind of a chemistry zealot is not common, and I doubt you'd have one.

I really do love mathematics, but my passion is repeated integration, triple and quadruple integrals specifically. I really don't feel that they get the recognition they deserve, and that they really are powerful tools, even more abstract, higher level mathematics can be encapsulated with their power and beauty, but disconcertingly, most other mathematicians just haven't seen this yet. Hell, just consider how they so beautifully they encapsulate all of space. Furthermore, they give us infinite precision, which let's us have the power to encode arbitrary structures within space. You could even encode and solve deep algebraic conjectures with these tools, which I find immensely beautiful since it shows a deep connection between the discrete and continuous, and this isn't even yet getting into their application in physics along with the underlying truths that triple and quadruple integrals imply about our physical reality, but sadly, it seems no one else will believe me on this since most other mathematicians like to use their ad hoc tools for solving problems, and even if I do get accepted into graduate school, I don't believe I'll be able to get my advisor to let research this topic that I truthfully do love.
What am I to do?

I am considering becoming, as a career, a historian and writer on the subject of mathematics.
What is the mathematics equivalent to a "popular scientist"? I've seen "Math communicator" before.
What degrees should I look into pursuing?

why the fuck is there even a square root sign if it has to be converted to a power of one half anyways?

...And the "power of one half" has, in some contexts, to be converted to the square root sign.
You're literally sperging out over the syntax of a function that could just as well be written as f(x) or sqrt(x)
