/sci/ - Science & Math

So I'm starting to really get into the curriculum of my mechanical engineering degree (second semester of my third year at CU), and I'm starting to think my passion isn't necessarily in engineering as a whole. I think it's cool stuff and all, but I still don't really know what engineers "do." I went into it to keep my options open, but I think my passion primarily lies in research. Everybody else here seems to have a huge hard-on for manufacturing though.

I was thinking of picking up a physics major (or at least a minor) to try and flesh out my theoretical background a bit more, especially since I don't know where my passion lies still. Would any anons have some insight on this?
