    Technical notes:
    This film allows us to visualize the dynamics of a
    differential equation, the Lorenz system. A “space
    ship” is following the trajectories; “planets” mark
    singularities of the system. Several mathematical
    experiments have been visualized; experiment 4 is
    presented here.
    Experiment 4 visualizes The Hat Function.
    Mathematicians started to study the hat function
    and noticed that it was possible to study
    something simpler instead, the parabola.
