DESCRIPTION:The first indirect detection of gravitational waves involved a
  binary system of neutron stars. Within a few years\, the first direct det
 ection may also involve binary systems -- inspiralling and merging binary 
 neutron stars or black holes. This means that it is essential to understan
 d in full detail the two-body problem in general relativity\, a notoriousl
 y difficult problem with a long and troubled history. One approach has bee
 n the "post-Newtonian approximation"\, which treats slow-motion and weak-f
 ield conditions. Yet recent results have shown that this approximation rem
 ains surprisingly valid well into the relativistic strong-field regime. We
  will describe the many arenas in which post-Newtonian theory has been unr
 easonably effective\, including binary pulsars\, "kicks" imparted to newly
  formed black holes\, and the gravitational wave signal from merging compa
 ct binaries.
