Hey, I am a math major looking to get my Ph.D. in Nuclear Engineering. Next semester I have to choose between two classes because of scheduling conflict (each class only offers one section; they are 30 minutes apart, but one is at another university which is 30min-1hr drive depending on traffic). I have to choose between: Numerical Analysis 2 Topics included will be numerical methods for systems of equations, differentiation and integration, approximation theory, initial and boundary value problems and problems for ordinary differential equations. Extensive use of computing will be incorporated. vs. Radiation Physics Characteristics of atomic and nuclear radiations, transition probabilities, radioactivity, classical and quantum-mechanical derivations of cross sections, interactions of photon, neutron, and charged particles with matter. Which do I choose?
