Physics- Pomona v. Columbia?

*In case you’ve seen this post before, I’m posting in multiple forums in order to reach the maximum amount of people; I’d really like feedback on this issue!

I’ve been accepted into both Pomona and Columbia and I’m conflicted as to which to go to. I’m planning to major in physics or astrophysics, and then go on to grad school- at the end of the line, I’m aiming for a teaching position at a college or university. Right now, I’m conflicted because I know I would love the environment at Pomona, but at the same time, I’m not sure how Pomona’s physics program compares to that of Columbia (I’ve heard plenty about how Pomona excels in all fields of study, but I haven’t found many discussions on physics in particular). I’ll be doing campus visits of both colleges in April, but for now, I’d still like to hear some additional opinions. Could current (astro)physics students at either school give me some insight as to what it’s like to study physics there?

Some questions I’d like answered (though any additional information would also be greatly, greatly appreciated!): how accessible are your professors? How easy is it to find research positions, even as an underclassman? How big are your classes? In general, why study physics at your respective school?

If you have anything else to weigh in about the two schools, just in general (atmosphere, lifestyle, etc.), I would greatly appreciate any kind of insight you have to offer.

Thanks in advance!
