What kind of physics do I need to study astronomy at home?
I want to study astronomy at home. They say I need knowledge in physics to study astronomy at home. I was in a library, and I found two large books in physics physics 1 and physics 2. What kind of physics do I need to be able to study astronomy at home. Can you suggest me a book in physics that I have to revise and I can then study astronomy. Do I need physics to understand the concepts in astronomy? I already know that I need calculus, linear algebra, diff equations...
