So I really have a few questions. First, is it wise to take the following classes in the same semester? Quantum Mechanics I - At the level of Griffiths' Intro to Quantum Mechanics, chapters 1-5ish Classical Dynamics - At the level of Thorton and Marion, Chapters 1-12, ends with coupled oscillations Linear Algebra and Matrix Theory - At the level of Andrilli and Hecker. This class is aimed at math majors with some emphasis on proofs, chapters 1-5.5, ends with isomorphism and diagonalization of linear operators Complex Analysis - At the level of Marsden and Hoffman, Chapters 1-5, ends with conformal mappings American Literature - Not very relevant to this discussion No that it matters, but I'll be taking 15 hours and I'm a math/physics major at UT Austin. You may have noticed that three of these classes is, some might say, essential to learning quantum mechanics. This leads to my second quesion: Would it be better to hold off quantum mechanics for the spring semester and get Classical, Linear Algebra, and Complex Analysis done first? I feel like I might not appreciate quantum mechanics as much, nor be fully capable of understanding or working out the problems if I don't know some of the math and physics. I hear some speak about hamoltonians showing up in Quantum, and I won't get to know about it until much later in my classical dynamics class. What topics from classical dynamics, complex analysis, and Linear Algebra show up in Quantum? Could it possibly be to my advantage to take all the same time that way I learn it and apply it nearly at the the time, hopefully? I should perhaps mention that I have elementary knowledge in linear algebra (as far as matrix multiplication) and I only know about complex numbers (no kind of differentiation or integration) with little knowledge of infinite series of complex numbers. Furthermore, the only knowledge I know about classical dynamics is calculus of variations and that's about it other than Newtonian mechanics. Thank you.
