Hey there /sci/, 2nd year undergrad in physics here, what advice have you got for following an academic career in theoretical physics? I'm already studying more advanced mathematics, but what else should I do while undergrad and after I get my degree?

Search through your uni's physics page and look for profs you would like to do research with. Go ask them if you can research with them. Try really hard to do good at research because this will get you good letters of rec and good experience. Don't let your GPA fall. Less than a 3.8 and most good schools won't look at your application. Make friends with at least three profs. You'll need them for letters of rec. Letters of rec are the most important after the GPA. Take as many physics/math course as you can while maintaining a proper gpa.
>>
>>9145935
Decide what you'd like to do in theoretical physics and research that topic. For instance, if you were interested in gravity you would maybe try to read some books on General relativity and quantum field theory. From there you would look into popular theories of gravity: string theory/ loop quantum gravity. You don't have to become an expert at this stage. Just learn the main talking point so when someone asks you why you want to do this, you'll have an answer.
>>
>>9145943
It's also a long road to getting a tenured position. You might consider doing something easier. If your doing well as a physics major, there are many other avenues you could go down that would be easier and pay more, but would maybe be less gratifying. Theoretical physics is a lot of fun. But you will have to move around a lot, and you will be under a lot of pressure for a long time.

Hope this helps OP

How do you accept the fact that every member of your family is intellectually weak and scientifically illiterate?

I hate to go reddit tier but I'm visiting home for the weekend and my sister was talking about monkeys she saw at the zoo and mentioned how they like like old people, and I made an offhand comment about our evolutionary ancestry

My dad then laughed and said "primate theory is unsubstantiated". Later that night he made me and my brother watch some religious self help show he's been into lately and after it was done I then I tried to show him the classic Carl Sagan evolution video from Cosmos and he started laughing and asked me how old Carl Sagan was when he died and I said I didn't know, then he chuckled and said 47 confidently (he's wrong its actually 62). He then gave me some word salad about scientific evidence being invalid or something, I couldn't quite follow it, then he stopped watching

Do you just have to accept that some people will live in intellectual squalor forever even on basic high school biology topics? This is my dad, I want to help him but he seems impossible to talk to on any real topic.

My father has this weird super autistic skepticism about cosmology. Whenever I show him pictures about the galaxy and junk he says he doesn't believe any of it and says it's all bullshit. He's not the creationist type that casts doubt on evolution or even the big bang as a concept though, strangely enough.

I dunno I mostly just ignore it there is no point with older people who are set in their ways.

Some people are fine living ignorant. Don't try to talk sense into him, just let hik believe what he wants to believe and, if you're up to it, concede partly to his viewpoint. People like him, the majority of people, find great comfort in thr though that there's a reason for everything and there is a god and whatnot. It's not up to people like us to shake them of their beliefs, what good will that do? Let them be comforted, let them go to their graves content and even happy. The only thing you do by convincing them of shit like that is instilling uncertainty and existential dread in them.

I know there's a god /sci/, there must be because only a god could be so cruel as to make me suffer from constant depression and anxiety issues, along side physical issues.

Evolution should have corrected all of these issues should it not? Or if we're still evolving I was simply born too early.

Why doesn't the brain have fail safes for such destructive issues?

Or do these issues only come up because of the technological world we now live in? Where everything is easy and finding fulfillment is near impossible?

>Evolution should have corrected all of these issues should it not?
No, it shouldn't. Why would you think it would? Evolution doesn't make organisms not have problems. If organisms can do well enough to survive to reproductive age and have offspring then their traits will propagate into the future, including harmful traits.
>>
>>9145647
Because those destructive issues should weeded out those types of individuals no?
>>
>>9145651
No. Having the mere possibility of developing depression and anxiety isn't enough to cause all carriers of that potential trait from failing to survive and reproduce. Your parents didn't die before reproducing, why should you expect every single carrier of that trait not to survive and reproduce?

some guy told me that whenever you select an object out of some box, if there are no distinguishing features when selecting, you must be invoking the axiom of choice.

also, mathematically speaking, is it possible to distinguish the motion of an object from the construction and destruction of that object over each point in space and time?

this is not true for finite numbers of bins.

>is it possible to distinguish the motion of an object from the construction and destruction of that object over each point in space and time?
it will only be an approximation of reality which is especially true for small objects like atoms or subatomic particles.

Dear, /sci/entists I come to you with a question I hope isn't a waste of your time.

Can a man in his twenties with no practical arithmetic skills become good at math or am I too far gone? I was not taught math beyond basic add/subtract in homeschool. I've always loved reading and thirst for knowledge but I've avoided learning arithmetic because it's an emotional wound of mine.

A coworker asked me to help her with making change because "you're the smart one". I give this impression because I'm well read and can talk about various trivia, geopolitics history ect. but deep down inside I know I'm fucking retarded. I genuinely considered blowing my brains out when I couldn't help her. I hate myself for being stupid.

What should I do to learn the useful arts?

Or will i never understand the esoteric beauty of exploring our reality so i should just kill myself?

So apparently bad air "quality" is now a buildup of Ozone due to no weather activity. I mean this is the type of stuff that naturally goes up into the stratosphere if it does not brake down to oxygen on the surface. It also says Ozone is a bluish haze but like all the images of bad air the sky is a brownish dark haze. How believable is this bullshit?

anime (on /sci/)


Ever been to /g/? Its PACKED full of these autists. It's also PACKED full of these autists posting anime, specifically the shitty japanese pedo cartoons you see here. Here's their weakness though, they are incredibly sensitive about their anime posting rights, and if they were revoked, the butthurt would entirely consume any motivation to participate in only the most rigorous of methmatics.

stewart -> intro to proofs -> spivak -> linear alg -> multivar calc -> discrete math

good enough math foundation for CS major?

>Stewart and Spivak
Literally why

This board is profoundly confused when it comes to learning calculus. I feel like the thought process is:
>Elite American schools use Spivak in their honors programs, so if I use Spivak I'll be smert two.
But they don't realize that the classes in those schools that cover Spivak don't just cover Spivak, they cover a ton of topics ranging from topology to affine geometry, the problem sets and lecture notes from those classes are 10000000x more valuable than the textbook, which the students in those classes don't even do problems from.

If you know calculus already, LEARN. REAL. ANALYSIS. There's no point in reading Spivak. Ever. REEEE.

Also do Joseph Rotman's A Journey into Mathematics. It's better than any of the other Proofs 4 Dummies books out there.
>>
>>9145429
i was gonna go with Rotman's proof book!!!
I know calc but I just wanna revisit calc just cuz
so what you're saying is that IF i insist going over Stewart, does my new plan sounds good?: stewart -> intro to proofs -> s̶p̶i̶v̶a̶k̶ ̶ -> linear alg -> multivar calc -> discrete math

We don't know the world as is, we perceive the world with our senses and interpret the information as best we can. I would like to believe there is a reality operating indifferent of our perception.

The world i perceive comes in a package of 3. 3 realities each in need of their own specific emotional structure. One is the natural world of survival of the fittest. Kill or be killed. Fight or flight.

The second is the social world. The complete opposite of the natural world. This world requires respect. Courtesy. Empathy. Sympathy. Compassion. Agreeableness.

The third is my own personal reality. I don't know what to label it as, schizophrenia maybe. This world is the torturous world of regret and sorrow in regards to the tragedies of life on earth. It is most intense in regards to my relationship with my parents. It has been rocky. I do not come from an affectionate family. We all pretend to be strong, but in reality we are all a fucking train wreck on the inside.

Constantly trying to organize my emotions around these 3 worlds is chaotic. Each world requires such a vastly different emotional structure, i am always struggling to obtain control and maintain the idea that i have a fucking clue. I'm so very desperate for understanding.

What's your life like?
