Edited sentence: , and the chaotic obliquity of Mars which has important implications for the past Martian climate., and tidal dissipation at arbitrary eccentricity and obliquity., the tidal heating and dynamics of Enceladus.His 1981 dissertation demonstrated for the first time the theoretical reason for the clearing of the Kirkwood gaps in the asteroid belt.His work has also brought to light the chaotic rotation of Hyperion, chaos in the orbital evolution of Pluto.In addition, Wisdom is credited with developing "numerous analytical and numerical techniques" that are fundamental to modern celestial mechanics, most notably the symplectic map for the n-body problem (developed together with Matthew J.More recently, Wisdom's work has shed light on the complex evolution of the Moon.Most revolutionarily, work with colleague Gerald Sussman using a specially-built computer, the Digital Orrery, demonstrated that the solar system as a whole is chaotic on a timescale of about four million years.This work was responsible for "shattering the long-held view of the clockwork motion of the planets.Wisdom pioneered the study of chaos in the solar system.from Rice University in 1976 and his Ph
