Jack Wisdom

Jack Wisdom is a Professor of Planetary Sciences at the Massachusetts Institute of Technology. He received his Ph.D from Caltech in 1981. His research interests are the dynamics of the Solar System.

Wisdom's 1981 dissertation demonstrated for the first time the theoretical reason for the clearing of the Kirkwood gaps in the asteroid belt.cite journal

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. Holman),cite journal

] which "now forms the core of nearly every solar system dynamics integration scheme in use today."

Jack Wisdom is co-author of Structure and Interpretation of Classical Mechanics. His 2003 paper in "Science"cite journal | author=Wisdom, Jack |title = Swimming in spacetime: motion by cyclic changes in body shape| journal=Science| volume=299| year=2003| pages=1865–1869| doi=10.1126/science.1081406 |pmid = 12610230] on a new geometric phase effect which Wisdom calls "spacetime swimming" has attracted considerable attention, although it is not yet clear whether this effect has practical utility or even can be used to devise new tests of relativistic gravitation theories.
