Hey /sci/ I am a First year undergrad planning to major in Physics.Although I donot participate much here, I get inspired daily on /sci/ regarding amount of books you guys have read and knowledge you guys have. My Uni syllabus is literal shit so I really manage that in small time, I have recently scheduled different subjects to learn like Comp Sci, Mathematics, Astronomy, Physics etc. But to manage like 6 subjects every day, I cannot allocate more than an Hour for each.
I really wanted some nice techniques to read faster ( I have below average reading speed, so I take shit load of time to read books, resulting in me not completing them). I want few techniques you guys do so that I read faster and also grasp everything in one go so that I dont have to read that again and again (Which usually happens when I read a book very fast).I realize Science and Math is fucking vast and doing them slowly will take me nowhere. I really want to read fast and memorize/understand in one go.
Please drop in any links if you have, which might give me more tips for this activity.

Reading advanced books isn't really related to reading speed, and is supposed to be much much slower compared to normal books
Here are a few nice explanations

>>
>>8600416
Open book to random page, go straight to exercises.
Attempt to solve exercise.
If successful, repeat until no exercises left.
If unsuccessful, research the book to find the answer then go back to previous step.
That's the fastest you can do a math book, at first it's slow going but then you start blazing off the exercises without reading entire chapters.

I think you should focus on doing problems instead of reading.
After attending the class, you should have some idea to approach the problem.
Try them while referring to the texts and explanations from the internet/friends/TAs/profs.
More efficient.
Passing a course means you're able to solve problems. Not about being able to read the text fast enough.
Obviously, it's easier if you don't take too much difficult courses in 1 semester. Pick your battles. Better to excel in a few core courses instead of taking all courses offered by the Physics, Math, and CS department.

When did you realize that you wanted to go into a STEM field? What inspired you to do so? Keep in mind Im not talking a specific topic per se, but like when a kid decides they want to go into a field, that kind of inspiration.
(ie. I knew since I was a kid that I wanted to go into math because I always really liked numbers)
What is your story, /sci/?

Any idea as to how? It doesn't have to be specific but are there any cutting-edge technologies that could be the very start of this? I understand that this won't be soon at all, but maybe we are at least at the point of kind of having a vague idea as to how...

Provide the unskilled and semiskilled labour required to ensure these automatons are doing there job properly.
You think a factory full of robots does it all under the command one super smart guy.
I think you're the brainlet problem desu.

How in the world did you guys get through your master thesis? It's fucking killing me. For the last 1.5 years I have worked nearly every day, weekends and "vacations" included and I'm not even close to finished.

Can /sci/ help me with a Statistical Mechanics problem?
sauce in in Italian: http://server2.phys.uniroma1.it/doc/crisanti/Teach/MecStat/Exams/MS_161114_co_t.pdf
I have a classical gas made up of N particles, contained in a cylinder with an height of L and a radius of 3R, with the axis along the z axis of a (x,y,z) frame of reference.
Each particles has an energy of [math]H(p,q) = \frac{p^2}{2m} +V(x,y)[/math], where the potential is [math]V(x,y)=V_{0}\frac{x^2+y^2}{R^2}[/math] for [math]\sqrt{x^2+y^2} < R[/math], [math]V(x,y)=V_{0}[/math] for [math]R < \sqrt{x^2+y^2} < 2R[/math], and [math]V(x,y)=2V_{0}[/math] for [math]2R < \sqrt{x^2+y^2} < 3R[/math].
I have to find:
1. Mean energy for every particle E(T)/N
2. The pressure at a distance R, 1.5 R, and 3R from the axis of the cylinder
So far I've managed to do the first by calculating the Z(N, T) canonical partition function and using the formula U(T) = -d/d[math]\beta[/math] log(Z(N,T))
I'm having trouble with the second part, and the solution provided lacks the algebraic steps that I probably got wrong
I've calculated the partiotion function of a cylinder with a radius of r<3R, so that the volume considered is not fixed, and I've used the P(T) = d/dV(r) log (Z(V(r))) to find the pressure at a given R.
The issue is that, in the solution given, the integral in the denominator in the boxed fraction in picrelated is calculated up to 3R, and not up to the generic r relative to the volume I'm considering.

im going to say yes... provided the width of the wall is about 0.25 inches.
>>
This is very basic math.
Height: 139m
Base: 230m
This gives a volume of 2,451,033m^3
Now The earth has a circumference of 40,075,017m and our 2ft height equals 0.61m.
This means our wall would have a width of 0.1m or 4 inches.
I would say that is a fair dimension for a stone wall.

>>8599401
My house is a sack of shit, and probably has enough drywall to build a wall around the earth.
It'd just have to be really thin, really short.

I don't think it has enough gravity to make an atmosphere feasible.
This is just conjecture, I don't have a piece of paper saying I know more than plebs.

>I don't think it has enough gravity to make an atmosphere feasible.
This is true. Basically you'd have to keep introducing atmosphere from somewhere to make up for the gradual loss of atmosphere into space over time.

I don't think that the moon's soil can grow things, even if there were atmosphere and water, correct me if i'm wrong
