The discovery of solitons: reproduce the results of this classic paper by Zabusky and Kruskal. Make the best pictures you can - you have much better technology than they had!
#3
Time-dependent schroedinger equation: reproduce these quantum-mechanical scattering experiments of a particle hitting a barrier. Make the best pictures you can - you have much better technology than they had!
#4
Spontaneous spatio-temporal patterns in a chemical reaction: generate an interesting movie of a solution of this reaction-diffusion equation.
