Lecture
This lecture covers topics such as Poincaré sections, non-linear stabilization of an unstable position, chaos with extreme sensitivity to initial conditions, and amplitude-dependent period. It also discusses the application of the Verlet scheme to oscillators and the behavior of excited and damped pendulums. The lecture explores the concept of strange attractors and the topology of Poincaré sections, showcasing the complexity of nonlinear phenomena in physics.
