Hello, everyone. I'm sorry if this is in the wrong place ... anyway ... I'm studying to be a biomedical researcher, but I have a great interest in physics and math, and I feel like I can't live without learning these sciences in a more deep way than I would need for my profession. Physics seems to me like the most essencial of the sciences. Problem is, I have to survive, and unfortunately, a physics job isn't very financially rewarding in Brazil. The point is, I want to know the stuff. I've considered getting a degree in physics after I get my current degree, but this seems too distant from the present. My question is, how realistic am I being if I consider learning modern theorethical physics on my own? I have already a good basis in math, but I probably would have to study math before actually getting to physics. The thing is I want to study the real thing, I've read some books on quantum physics and relativity, but they're meant for the layman, they're more of exposing the facts than actually showing you why we know the facts are the facts. Hope I made myself clear. Thanks, great forum.
