IE is actually more broad-based than physics; because of its roots in math, stats, economics, computer science and even ergonomics and management.

Well, I was in your shoes as a sophomore, being an IE major who loved physics. Eventually I decided that physics could just be a part-time interest, and I have never regretted studying IE. The job prospects are definitely better, although they may not be as exciting as being a physicist? :)

As time past, I realised that my interest in stats, maths and comp science grew while my interest in physics declined. Probably because I was starting to see the practical value of math and stats in solving everyday IE problems. Cheers.
