This volume reflects the proceedings from an international conference on celestial mechanics held at Northwestern University (Evanston, Illinois) in celebration of Donald Saari's 60th birthday. Many leading experts and researchers presented their recent results. Don Saari's significant contribution to the field came in the late 1960s through a series of important works. His work revived the singularity theory in the $n$-body problem which was started by Poincare and Painleve. Saari's solution of the Littlewood conjecture, his work on singularities, collision and noncollision, on central configurations, his decompositions of configurational velocities, are still much studied today and were reflected throughout the conference.
