First lecture Fairy Tales
was about KdV equation, the spectacular advance of early Dutch science. There were many students. I was flattened with the fact that most were familiar with the Lagrangian, and variational calculations in this context. I begin to believe in progress and knowledge accumulation since I did not quite see this in former generation.
Moreover, the students were able to correctly describe the activities of a theoretical physicist. Well, I was rather inspired with this fact and has spent too much time on introduction for the sake of exact solution technology – just had time to mention it briefly.
