1. The problem statement, all variables and given/known data In my last year in this step of my education I'm going to construct a project based on the subjects of physics and mathematics. 2. Relevant equations So I was wondering if you had any ideas to an exciting and maybe even bit difficult subject to work with. I don't care if it's a really difficult subject though ;) So I can get a good idea of what I'm gonna deal with. 3. The attempt at a solution The subjects I like really most in physics, is things like: Einsteins equations, subatomic scales, nuclear physics and atomic physics. So things like that.
