Note on multiple majors: Students often pursue two or even three majors. Physics and/or Astronomy are easily combined with Mathematics and/or Computer Science. The B.S. programs in Physics or Astronomy require almost all the Mathematics courses needed for a B.S. in Math. Other majors or minors that have been successfully combined with Physics and/or Astronomy are Chemistry, Philosophy, Biology and English. Individualized majors and minors are also possible.
