I am an Electrical Engineer. I have a MS degree. Soon after graduation, I started working for physicists. At work, I found I was lacking some fundamental concepts. Nobody said I was a bad engineer. Everything I designed worked. But the way physicists think is much different. Much more fundamental and one idea builds on the other and there is continuation. I want to pursue a degree in Electromagnetics/Quantum physics or Particle physics. But I know my weakness. Its math. At undergrad level, I used to solve problems fine when I took math courses. Never really cared what they meant. But now, I find myself at a loss when I see math equations being used(like in research papers etc). I need to build up my math fundamentals. Do you guys have any suggestions/thoughts? Go for a math degree?
