Somehow I missed my registration notification for Fall and the E&M and Mathematical Physics classes are full. I am an astrophysics major. I wanted to take nuclear physics, but it will not be offered again until Fall 2014. I will be taking thermodynamics in the fall, but I am wondering if I should take solid state physics. Is solid state physics important in astrophysics? Reading the course description, I can think of many ways in which it can be useful in astrophysics, but I am wondering if it is essential as I will probably have to eliminate taking a math class such as probability and statistics in order to fit it in my schedule.
