Hi, I'm in a slightly odd situation as I am not directly enrolled in a Physics program but am highly interested in certain topics (e.g. Plasma Physics, Thermodynamics, Fluid Dynamics, Particle Physics, Theories). I am actually enrolled in a Biochemistry program but will hopefully be either majoring or minoring in Applied Mathematics. Now, besides Introductory Physics and my own reading of topics, I have not formally furthered my studies in Physics, albeit I am very interested. My question is: for a student from a non-physics background (but one with math), is it feasible to pursue graduate studies in one of the aforementioned topics in Physics? (Sorry for the incredibly broad question!) I currently reside in Ontario, Canada and most programs don't require the GRE, so is there any other way to really see if I'm apt for further studies in the field? Do supervisors typically take on students from different fields like this? What are some essential or highly advisable math courses a student pursuing Physics from a non-Physics background should take? What are some good materials to read (would you recommend doing the problems in these books as well, or just reading?) when pursuing these fields in Physics? What level of programming and computer science knowledge should students looking at Physics grad programs have? For instance, beyond Calculus III & IV, Linear Algebra I, Ordinary and Partial Differential Equations, are there any other highly advisable courses? Sorry if this too general and please ask for further clarifications if needed! Thank you!
