Hey! I have to do a work about one of the many applications of mathematics. I have to study the math behind a certain subject and use matlab to solve some kind of problem associated with the topic. I am on the final year of graduation and I thought of doing about optics, fractals, relativity or paintings/architecture (perspective, etc.). I wouldn't like to spend a lot of time on this and I thought of doing about optics or something related to physics as I am in the final year of gaduation. Do you know any interesting application of mathematics? (doesn't have to be connected to physics) Thank you.
