In astrophysics, we use ideas from the various parts of physics - electromagnetism, gravitation, theory of matter, mechanics, quantum theory - to explain what we can see. It’s like being a detective. There is what we observe (the evidence) and there is piecing it together (the thinking). The first year, and a major part of the second year, cover skills and the fundamental principles. The .
