Which course should I take? (General/Special Relativity or Astrophysics)

Click For Summary

Discussion Overview

The discussion revolves around the decision of whether to take a course in General/Special Relativity or Astrophysics as part of a physics program. Participants explore the implications of each choice in terms of difficulty, content, and future academic plans.

Discussion Character

  • Debate/contested
  • Exploratory
  • Conceptual clarification

Main Points Raised

  • One participant expresses a strong interest in gravity and celestial mechanics, suggesting a preference for the more mathematically intensive GR/SR course.
  • Another participant, despite being a beginner, argues that learning Special Relativity (SR) and then General Relativity (GR) should precede studying astrophysics.
  • A participant questions how future academic plans might influence the choice, suggesting that if neither field is pursued post-graduation, the decision may be less critical.
  • One participant considering graduate school in astrophysics expresses concern that the astrophysics course may not be rigorous enough and leans towards GR/SR instead.
  • Another participant encourages taking the GR/SR course, suggesting that the astrophysics course might be more descriptive and easier to learn independently.
  • A PhD candidate shares their experience with a similar astrophysics class, noting that while it was enjoyable and memorable, they found their undergraduate GR course lacking in rigor.
  • A participant expresses concern about potentially being stuck in a less engaging class and seeks reassurance about their choice.

Areas of Agreement / Disagreement

Participants do not reach a consensus on which course to take, as multiple competing views remain regarding the value and rigor of each course option.

Contextual Notes

Some participants note the lack of detailed course descriptions and the importance of consulting academic advisors, indicating that specific course content and expectations are unclear.

I'm about to be a senior in the physics program. I can choose General/Special Relativity or Astrophysics. The astrophysics course is not as intensive - the GR/SR course requires mechanics and is more math-savvy. I've been doing some modeling with Lagrangian mechanics for star systems etc. and I've found anything having to do with gravity and stars/planets fascinating (for the most part). I don't know a single thing about GR/SR except some basic lorentz transformations and such. What would you do? Why?

When I was 20, I will always remember: I was in doubt whether to eat a snack or wait at lunchtime: my best friend stared at me and asked me: what do you want? I said: "A snack".
What do I mean? You are the only one who knows the answer.
I will give my choice, if I was in your place: Relativity. Why? First of all I confess you I'm an absolute beginner in physics, but I think that first of all, the first lesson to take before learning astrophysics, is to learn SR, and then GR. But this will not help you; it shouldn't. I hope so.
Vitany1, it's a poor answer; I'm sorry:cry:. Hope someone more wise than me answers you. Greetings!
 
What is your plan after graduation? That should provide some clue as to what is more important. If your plan does not include anything related to astrophysics or GR then I guess it is a tossup.
 
I am thinking about graduate school in astrophysics. I'm afraid this astro course is plug and chug (the required courses don't exceed something like calculus two and a general physics course) so even if I was interested in the field I don't know if it would be worth my time at this point. If you've ever played world of warcraft it's like when your enemy's name becomes grey because you are a higher level but their could still be some nice loot. I think I might go with SR/GR.

Go for it. The astrophysics course may be basically descriptive which you might more easily pick up on your own vis-a-vis GR.
 
I am a PhD candidate that does research in relativity, and I took a similar astrophysics class during undergrad (in terms of requirements, only calculus two and modern physics was required!) and at the time I had a similar opinion of it being a waste. EDIT: The book we used was "Introduction to Modern Astrophysics" by Carroll and Ostile just so you can compare to your own course.

Of all my undergraduate classes, that's the one I remember the most from. It presented information in easily digestible chunks that I was able to tell my friends and family members some cool facts about stars that I still share to this day, and that I attempt to use on children to keep them interested in science when I tutor math once in a while. My undergraduate GR course, however, left a lot to be desired. The rigor just wasn't there, and I suspect that would be the case for a lot of them.

But, I guess without real course descriptions and books, we can only speculate (as I did above), so always talk to your academic advisor if you haven't.
 
This astrophysics book is also the book I would be using. I'm just worried about getting stuck in a class where I'm plug and chugging all day and not doing anything useful. Thank you for your feedback. I have ~5 days until school stars so there exists some time to choose.
