Physics vs Astrophysics as a 4yr major

Click For Summary
SUMMARY

The discussion centers on the decision between pursuing a Bachelor's degree in Physics versus Astrophysics for aspiring astronomers. The consensus is that a Physics degree provides a solid foundation for graduate studies in Astronomy and Space Sciences, as evidenced by Johns Hopkins University’s recommendation to major in Physics before specializing. The courses listed for both majors highlight the differences, with Astrophysics including specialized topics like Orbital Mechanics and Astrophysics I & II. Ultimately, the participant has decided to pursue a Physics degree, which will allow them to take relevant astrophysics electives.

PREREQUISITES

Physics vs Astrophysics as a 4yr major :)

Hello,

I am currently working on my AAS in Physics and am aspiring to be an Astronomer. The area that I live in does not have any colleges which have astrophysics as a major. I will be transferring to a University in a year or so to complete my Bachelor's and I was wondering if I should just stay local and do physics, or if I should relocate to another city or state to do astrophysics. Does it make a major difference having a degree in physics vs astrophysics when working on your graduate degrees in Astronomy/Space Sciences? Is it worth the move, or should I stay and just do a regular physics degree? Thanks for your answers!

Here is a list of the courses for the physics major (junior and senior year) at a school near to me:

JUNIOR YEAR
TERM FIVE

* Modern Physics (3SH)
* Modern Physics Laboratory (1SH)
* Mathematical Physics (3SH)
* Optics (3SH)
* Free Electives (6SH)

TERM SIX

* Quantum Mechanics (4SH)
* Electronics for Scientists with Lab (4SH)
* Classical Mechanics (4SH)
* Free Elective (3SH)

SENIOR YEAR
TERM SEVEN

* Electricity and Magnetism (4SH)
* Advanced Physics Laboratory (2SH)
* Free Elective (3SH)
* Free Electives (6SH)

TERM EIGHT

That depends on what you want to do with it. If you plan on going to grad school, getting a degree in general physics won't hinder your ability to get into an astrophysics graduate program.

In fact, Johns Hopkins University states that they do not offer an undergrad degree in astrophysics because they feel it's better to get a strong foundation in physics before specializing in astrophysics.
 


Thanks Jack :) I want to go into Astrophysics/Space Sciences in grad school and I was wondering if it would be a smooth transition with Physics for undergrad or if Astrophysics would give me a major advantage. I really appreciate your answer!

In fact, here is exactly what Johns Hopkins says:

Want to be an astronomer or an astrophysicist?

We are often asked whether we offer an undergraduate major in astronomy. We don’t, and for a good reason. The best way to become an astronomer or an astrophysicist is to start with a solid foundation in physics, and that means being a physics major. We do offer a variety of upper level courses on astronomical subjects, and of course there are many opportunities for undergraduates to involve themselves in research. About half of our students who go on to graduate school enroll in physics programs, and the other half in astronomy and astrophysics.

Thanks again Jack! Very helpful! I've decided to do physics for undergrad. :approve:
 


Well good news...the school I will be transferring to will have astrophysics I & II as electives under the physics major...they previously had astronomy I solely. I have another question now...but I think it needs a different thread.
