I can take one of the following 3 courses as a technical elective. I need to know which would be the most useful to me. My Math background: I have taken a year of Calculus, linear algebra, and diff eq (no partials.) Thermal Physics [text: Kittel "Thermal Physics"]: http://cosmology.berkeley.edu/Classes/S2005/Phys112/ Math for physical Sciences course A [Text: Boas "Mathematics for the Physical Sciences"]: http://math.berkeley.edu/~reb/courses/121A/ Math for physical Sciences course B: http://math.berkeley.edu/~reb/courses/121B/ Realistically, I will probably not be able to fit two of these courses in in my time here. Would the physics course be good? would I have or be able to pick up the math for it as needed ? Please give your opinion. Thank you.
