I've just finished my first year of physics, and Serway's books, while the best of the bunch (Yuropoor here, so not many choices), I think weren't all that good. Info was ommited, tons of stuff were left up in the air and it had the most basic of examples, while having some darn hard exercises. Considering that classes were a waste of time, I found that it wasn't that useful a book if that's your only resource.
Am I just a brainlet or have others had similar experiences with his books?
>>9118252
I hate Serway, 1k pages for teaching the basic physics insights, aced all physics only reading Feynman :^)
>>9118339
What'd you use for Optics and the like? I have Serway's V2 of pic related & I bought McGraw-Hill's, but I haven't opened that yet.

I don't get it.

you should aim to no fap, cum in her, then cum in her again in 20 minutes
that's a mix of old and new

That's not how this works, that not how any of this works!
Hello /sci/,
Who here listens to white noise while studying/concentrating? I find that it drowns out all the brainwashing one is exposed to on a daily basis. I prefer the Brownian (even power spectrum) noise.
Wow you're autistic
Same here, but brown noise is far to harsh for me, I prefer recordings of your mother talking dirty to a black man.
>>9118196
Me. I even downloaded that shit .swf for offline use. The Brownian is the best.
Hi /sci/, poorfag from 3rd world shithole here. I finished high school a year ago and I want to learn calculus so that I can have a base to study machine learning. I never had any calculus lessons at school but I am pretty proficient in algebra and trigonometry. What are some book
recommendations to start learning basic calculus with little mathematics background?
Aren't 3rd world shitholes supposed to teach more maths in high school than in western countries? At least in the post-commies you get 2 years of caluclus and linear algebra, and a bit of abstract algebra
Anyway, check the sticky.

Where are you from?
Rudin is a good one for analysis, then read some book on stats.
My hand bumped into a face, how bad is my hand? To me it looks broken. I appreciate any of your advice
the results are in and you broke your hand
I've been offered the option to learn an advanced math topic at school
Topics I'm offered are: differentiation, integration, and complex numbers
Which topic would be best for me to learn?
I'm thinking of studying physics at university next year btw
I'm also considering studying oceanography next year, so when taking a biology course next year at uni, should I take a cell biology course or an animal biology course?
Which one would be more important for studying the deep sea?
>high school
Oh sweet summer child...
Just pick up a book on calculus and have them help you with that.
>>9117956
Winter in my country
What's a good book on calculus?
Preferably something with basics, because I haven't learnt calculus yet
Any MDs regret their path?
Yeah. Residency sucked but after those 6 years ir became comcy as fuck

Why are some girls super assertive when low test and high est would suggest the opposite?
If they do in fact have higher test, why aren't assertive/ brave women more phenotypically male?
Human personality has incredible diversity and is not solely the result of testosterone or estrogen levels
Progesterone is the hormone that creates the desire to be protected/ dominated/ submissiveness in women. High Estradiol leads to dominance, like testosterone in men.
Women who are submissive have high progesterone and low estrogen. Alpha women have high Estrogen and low progesterone.
This is probably why Asians are so submissive and lack curves, maybe they have lower estrogen than other races.

Time to start taking progesterone
What has ever become out of nuclear propulsion space travel? It was abandoned in the 70s afaiu, but only because of the cold war. Why isn't it considered today? Why is there no billionaire financing a nuclear propulsion spacecraft?
>>9117713
>It was abandoned in the 70s afaiu
It was never real, therefore saying it was "abandoned" at any particular time isn't quite right.
>but only because of the cold war.
???
>Why is there no billionaire financing a nuclear propulsion spacecraft?
Because even billionaires can't buy nuclear weapons.
>>9117713
NASA is working on fission-fusion propulsion already. That tech might eventually be available to the American private sector hopefully.
>>9117723
actually they did a grounded nuclear rocket test. it actually fucked up background radiation levels in Idaho iirc. cold war style playing around with nuclear shit
Just how important is Calculus of Variations for a physicist? I don't enjoy it.
Very important!
>>9117562
Very.
https://en.wikipedia.org/wiki/Principle_of_least_action
>he doesn't enjoy the comfy variational lemma and everything it brings him
Very sad desu. Maybe engineering is more your speed.
not exceptionally important, certainly not in its rigorous formulation, in most cases I get the feeling that physicists don't exactly know what they are talking about when they 'vary the action', so I wouldn't worry about it too much. pde's are far and away more important, and that should be any undergraduate's/beginning graduate's central focus.

just became interested in linguistics. Read the wiki, where should I start?
Noam Chomsky and anarcho-syndicalism.

>Predicted in 1916 by Albert Einstein, there are gravitational waves: ripples in the metric of spacetime that propagate at the speed of light
What is the metric of spacetime? Is it analogous to a fabric extended throughout space? Is it space itself?
>>9117372
A metric is, pretty generally, a function ("bilinear form") that takes in two vectors in a space and produces a real number that we interpret as "distance".
The normal Euclidean metric in the plane is probably pretty familiar, ds^2 = dx^2 + dy^2. Curved space-time has somewhat more complicated metrics in the presence of mass.
>>9117386
Basically it's saying distances in space-time get warped by gravitational waves.
>>9117386
So it's a mathematical construct representing a geometric quantity?

Because your balding head matters less than someone's boots touching a rock.
If electrons are negatively charged and attracted to positively charged matter, and electrons are the medium for eletrical current, then why does academia still teach that electrical current travels from positive to negative instead of the other way around? What kind of travesty in modern physics is this? How do (((they))) benefit from this incorrect physics model? Why hadn't it changed yet?
>>9117031
It's convention. Too many electronics are based on it to go back now.
>>9117037
But that's fucking retarded, we're going to teach pseudo-science as a society because to many idiots use it as convention now?
>>9117031
Electrons are not the only ones that carry charge. Sometimes its ions, sometimes its electron vacancies in lattice. So better stick to this old convention and dont stir the shit
