Hello, for my degree I have to choose one of the two following classes. I am planning to pursue applied physics, specifically atomic, condensed matter or chemical physics. So, which should I take? 1) applied vector and tensor mathematics Introduction to vector and tensor mathematics with applications. Topics include vectors; vector differential calculus, space curves; dyadic products and matrices; gradients, divergence, curl, Laplacians; Stokes' integral theorem, Gauss theorem, conservation laws; curvilinear coordinates; tensors, material derivatives; applications of potential theory in electricity and magnetism, heat transfer, solid and fluid mechanics. 2. Nonlinear dynamics and chaos Ordinary differential equations and dynamical systems via a modern geometric approach, including physical and engineering applications. May include chaotic phenomena and fractals. Much appreciated!
