Chcę zacząć z astrofizyką, jak?

9 Upvotes

Nie mam żadnego wykształcenia, jestem dobry z matematyki i fizyki, i lubię te przedmioty. Dlatego właśnie chcę zacząć z astrofizyką, ta dziedzina jest fascynująca.

Dlatego właśnie pytam jak zacząć. Od książek? Może stron internetowych? Albo filmów? Może jednak jakiś kanał na social media? A może też od czegoś innego, o czym jeszcze nie słyszałem.

Dziękuję za każdą odpowiedź.

Is astrophysics the wrong degree for me?

2 Upvotes

So I'm a high schooler in the US. My grades are pretty good, 3.9 unweighted GPA, 35 ACT, solid math and science APs. I really enjoy math and sciences (particularly physics and bio). I'm also a huge space nerd so there's that. And I want to go into something space related, and for the longest time I thought it was astrophysics. Then I started doing research and found that most people either stay in academia and research or switch into another industry.

My goals are to work on deep space telescopes (exoplanets, supernovae, dark matter investigations, etc.). But the real pipe dream is to get into a space program and become an astronaut. I don't want to do research all my life. I don't want to teach.

I think, depending on costs of living and the job market, I want to go up to at least a masters, then we'll see. I want to have a stable job before going for the space program, just so I'm not floating for years on end.

So I was wondering what degrees could help me achieve this, and if i should pivot away from astrophysics and to something else; I also wanted to know, what impacts has AI had on the job market and the jobs themselves?
