Thanks you very much :)

well there are several,but the most advanced I've done yet are:conservation of total energy and degration of energy in physics and in math there are actually several ones so i can't list them all,but the most I've studied in equations for example is 4th level

High school to university level

By astrophysics i mean the physics (laws for example)of the space and the stars

Can you tell me what's a good book to get me started in astrophysics? P.S. I have already read Big Bang by simon singh and A Brief History of Time by stephen hawking but they're astronomy books PS2 I'm 15
