Hi! :) I’m currently studying under a B.S Chemical Engineering program but i’m thinking of shifting to applied physics. What are the advantages of applied physics to chemical engineering? would it be better to stay on my current course?

I’m afraid that taking engineering would only teach me how things work and not why exactly these “things” work. I’m afraid I would just be stuck on the manuals or the routines set by the companies without actually understanding how and why the method or the system works.
