@MYOS1634 Lawrence is not strong in physics… they only have 4 full-time professors (and a number of retired professors and visiting professors). There class schedule in physics is incredibly limited. Not counting the first year intro sequence, they generally offer only 2 upper division courses per term.
The OP is interested in astronomy & astrophysics. Lawrence offers 1 astronomy course for non-majors, and only 1 “topics in astrophysics” course that isn’t even regularly offered.
