This topic is concerned with the application of computational

dynamics tools to the problem of transport in celestial mechanics and

molecular systems. The celestial problems are typified by computing the

probability that a member of the Hilda group of asteroids (which are

just inside the orbit of Jupiter) cross the orbit of Mars in a certain

interval of time. In the molecular context, the computation of the

ionization rate of the Rydberg atom will be used to illustrate the

techniques.
