Am I wrong, or is physics just about solving differential equations? I am nearly at the end of my secon year as an undergrad, and it seems to me that all I've been doing this year is solving DEs in physics. Is this all physics is about? If I carry on with physics, to postgrad, is this what I will be doing all the time, solving differential equations? A final year student told me she thinks physics is just a branch of applied maths, I think I agree. Side Note: Why then, don't we have a year whn we are just taught the maths we need: calculus, linear algebra, DEs before we start o physics.
