Philosophy: simplify, understand, generalize
- Start with simplified ODE/PDE problems
- Learn to reason about the discretization
- Learn to implement, verify, and experiment
- Understand the method, program, and results
- Generalize the problem, method, and program
This is the power of applied mathematics!
