Computational Physics Ph.D. here...I don't know about that. I have written lots of code (not just using off-the-shelf packages) to solve Hamiltonian mechanics and Quantum reactive scattering. OMG, I spent about 30 minutes going through the Hamiltonian mechanics chapter from the point of view of a mathematician and I got lost about half way through. I feel like in my fairly long career I learned just enough of the math to make it work, but don't really understand the math at a fundamental level like I do the physics.
