Wait, exactly how does osmosis work? Because simple diffusion down concentration gradients doesn't make sense...
Why the fuck do they obfuscate the issue by saying water 'wants' to do anything ffs.
>>7960063
Everything 'wants' to reestablish equilibrium
Diffusion itself is the movement of a solute from a high concentration to a low concentration. This is due to there being a higher chance of the solute particles colliding in the high concentration areas and thus, causing the solute to 'spread out' more and move to the lower concentrated areas.
Osmosis is exactly like diffusion, but instead of solute particles colliding and moving to lower concentrations, there's a semi-permeable membrane which prevents this from occuring. Therefore, instead, the water particles, acting similarly to the solute in diffusion, have a higher chance to collide in higher concentrations and thus, 'spread out' (diffuse) across the semi-permeable membrane and move towards the area of lower concentrations of water molecules.
it doesn't 'want' to do anything, the random movement of particles just means more would pass through a membrane from an area of higher concentration till the density is equal on both sides, where the movement of particles over the membrane is negligible since roughly the same volume would do so
Is there a reason to allow mediocre people to have kids? Imagine how great the world would be if only people of IQs 125 and up were allowed to have kids. It a statistical fact that IQ directly correlates with the success of a nation.

I'm a high school student who's aspiring to be a physicist. And of course to do that Ii have to have a solid foundation of mathematics and basic science. How good is pic related at providing a foundation. It really seems complicated and for experienced persons but If it truly is fundamental to my education I will study it.
Also good sources of information thread.
>>7959727
That book tries to cover way too much information for one book. Not worth it.
>>7959727
why don't you get an intro physics text like Halliday/Resnick
and then Taylor's Classical mechanics
both can be downloaded for free at libgen.io
there are many other texts and topics, of course, but the two above will be a good place for you to begin
>>7959727
>a solid foundation
will require hundreds/thousands of books
there's no "here's your foundation" book
just read it - if reading one book is a big enough event to warrant any serious consternation or debate then you'll never make it

How do you learn analysis effectively?
Do I have to memorize every single definitions, theorem, lemma, corollary, remarks?
If so then I'm really fucked.
Pick up a good book like abbott or rudin and do the exercises
As everybody should know the only way of learning math is by doing math. You'll find that you'll spend so much time doing proofs that you should be able to recite the theorems and def in your sleep.
>>7959604
Thanks. I'm working on Rudin's and Tao's book.
However, Tao's book does not have its solutions available. How can I know if I got the correct proofs?
I'm studying by myself so I can't ask anyone in my school.
>>7959612
You can email terry tao himself and see if that gets you anywhere, but just doing the rudin exercises would probably suffice
from a brain/neurologic point of view, what makes some people so confident?
>>7959564
I know confidence is an illusion if one were to think about it. It is a fallacy.
we aren't anywhere near explaining social behavior from a brain/neurologic point of view. but i used to be the /r9k/ type and now i'm always hanging out at bars, feeling comfortable at concerts, and getting girls' numbers, and this is how i understand confidence.
we are social animals, and in social situations people are always looking at each other and exchanging social cues. being confident is mostly a matter of faking it until you actually become slightly delusional. people have no idea what is going on in your head, so if you just act like you're the shit and don't overdo it, people will perceive confidence. if you slip up, just own up to your mistake and move on. and that's the best you can do, really.
but if you meant like "how do people end up like douchebags in this pic" i believe some people only surround themselves with likeminded sycophants and they end up being overconfident to some extreme, which results in odd fashion choices and the like. again, confidence is a kind of delusion.

Shitty education general

Your options for more reputable universities are fairly limited. Kings is somewhat close to the top of many league tables.

I found a dealer who sells Nafion membranes covered with carbon-Pt meshes for electrodes so I was thinking of buying one and assembling a cell for a project.
I've been using Soda (NaOH) + Aluminum Foil (Al) and Water (H20) to generate Sodium Aluminate and Hydrogen. It works well enough to generate pressure and fill baloons. The problem is that I need to carry more in less space, I need it pressurized.
I've found a guy on youtube who made the exact same reaction inside a fire extinquisher (reagents were added by unscrewing the valve) and that's probably the next darwin-award winning idea I'm going to try.
I'm looking for alternatives to CO2 car fire-extinquishers, other types of readily availible pressure cans I could use, perhaps a way to generate the pressure on demand by controlling the chemical reaction? Any ideas?
The idea of course is DIY so "buy a H2 can" is not an answer. :)
buy an h2 can
Dude just buy an h2 can XD
"DIY" ...?
I was really interested in fluid dynamics. What are some good subfields in biomedical?
Something more frindly to guys with a good background in solid/fluid mechanics

Transport systems, you'll probabaly be working with kidney shit mosty
but desu, bioinformatics is god tier
t. BME in the south in bioinformatics

bioinformatics is cool., but I;'m not sure I have teh background for it. What universities have good programs in transport programs . (I'm a b-student so not the tip-top unis).
>>7958618
like gene stuff right? I find biomathematics and dynamical modeling cool, But BLASTing genes all day is boring.
I was the only one in my cohort to get the answer to this one, not sure if I'm smart or I'm in a shitty degree mill full of idiots, please help /sci/ !
Can you solve pic related?

not enough context for the problem to be obvious. If you're doing a lesson on encoding it would be. Otherwise you could waste a lot of time trying to find rules for this sort of thing.
Hello, /sci/, no dark matter guy here again.
I use to base my hypothesis on the concept of nonsingularity. However my research revealed that singularities would not be tossed out so easily. This issue was surprisingly an easy fit into string theory.

You misspelled in the title.
But good luck. Make someone happy and just fucking start trying to prove the information paradox with holograms but instead of needing a computer to render the virtual image make the image as a combinatorial self referencing Mandelbrot or something. Because the Mandelbrot somehow has to render itself using it's own machinery, probably. Nonsingular? Solitary? Come on now. There are too many moving parts here to not fit plurality in with itself somewhere.

Is breathing out of your mouth constantly associated with low intelligence?
low EQ maybe
breathing through your nose is considered more polite, and manners are a sign of higher intelligence compared to the absence of

Ugly people in general are considered to be unintelligent for obvious reasons.
What kind of jobs can you get with a math major? Or what jobs do you any of you with a maths degree have? I'm studying math but considering switching to computer science for a good job.
I majored in math and minored in Comp Sci and was afforded the same job opportunities as the Comp Sci majors with the only difference being I'm not cucked if I want to go for more education or transition careers.
This is probably bait anyways.
The only math major I know has a PhD in math and work in risk management at an investment bank.
If the Australian government suddenly decided to massive channels inland to the center of Australia that connected with existing or manmade lakes.
Then connected theses channels to the ocean.
What effect would it have on Australia climate?
>>7958150
Hey buddy do you see any blue areas there? Australia is all above sea level.
>>7958159
Not OP, but channels are when you dig dirt out, get it? That means you can bring seawater in. Check out the Suez and Panama canals.
OP:
It would make the interior green by allowing evaporation and rainfall I imagine. I also imagine it would fuck up aquifers by salting them.
I'm all for it though. Fuck it. Give it a go. Can't make the area shittier.
>>7958169
Said Canals connect two fairly close segments of water, inland australia is like 600+km away from a coast. Also it won't fill into any non-dug areas because, as mentioned, all of the inland regions are above sea level.
