A New View of Scientific Rationalityan important special case, we discuss free proper actions and related bundle structures. In the final two sections, we study invariant vector fields and make some elementary remarks on relative equilibria and relatively periodic integral curves. This is relevant for the study of Hamiltonian systems

The normal form of the Hamiltonian induces a foliation of the phase space into invariant tori so that, in the normal form approximation, the theory becomes integrable. Moreover, we prove the Birkhoff-Lewis Theorem, which

Finally, we give an introduction to the study of qualitative dyna
