Hello, I'm curious about what kind of academic paths would lead to weapon design and research. Right now I'm doing a BS in physics and will likely pick a sub-minor in Mechanics or Electronics. There is also computational physics, condensed matter, and cosmology sub disciplines at my school. I'm planning to take chemistry courses at my uni to keep options open for graduate schools. What kind of field would one go for in graduate school? optics? condensed matter? I'm a Canadian citizen btw.
