Hello, I thought I would post here since I'm trying to prepare for my upcoming semester. I am transferring from a community college to a top 50 university to major in physics. However there is a bit of a snag and I could use some advice.. I have taken diff eq, linear algebra, calc I - III at my current college, but I have only taken up through physics 2 (e&m) since this is all they had to offer. The university I am transferring to has their physics 3(waves, etc) listed as a pre-req for half of their junior classes, but they only offer physics 3 in the spring.. I do not want to fall behind, but at the same time I don't want to get in over my head. There are only two recommended classes I know for sure that I can take which are Classical Mechanics I and Fourier Analysis. Mechanics description (Mathematical introduction; review of elementary mechanics; central force problems; conservation theorems and applications; Fourier and Green's functions; variational calculus and Lagrangian multipliers; Lagrangian and Hamiltonian formulation of mechanics is introduced and applied; oscillations; normal mode theory; rigid body dynamics. The course is designed to satisfy part of the upper-level writing requirement.) Fourier description (Fourier series and convergence theorems. Orthogonal polynomials. Applications to some partial differential equations. Fourier transforms. ) What I wonder is what should I do to fill out the rest of my schedule? I have contemplated signing up for another upper level mathematics class, but I worry that this might be too much for my feeble brain to handle :)...I have also contacted the undergraduate advisor for some guidance but he has yet to get back to me. Also the other two recommended junior classes (which have phys 3 as a pre-req) are E&M 1 (advanced electromagnetism) and Introduction to the milky way: Introduction to the internal physics and astronomy of galaxies using the Milky Way as a primary example. The course will focus on the dynamics of stars and gas inside galaxies and how gravity works therein to produce the observed stellar motions and internal structures. The course will discuss both the observations and the theory of galactic structure. Homework problems and two in class exams. Any advice will truly be greatly appreciated.. Thank you.
