Numerical Relativity.

Early 1970’s – DeWitt in Texas had students look into

solving Einstein’s equations with computer.

Larry Smarr was one of first.

As detectors began to be planned, challenge of what

to look for arose. Groups began to be formed and

techniques developed.

Matt Choptuik, a student at UBC in 1980, and now

faculty member, brought in key ideas into the field

(eg Multigrid, Independent residual evaluation...).

2005-- Frans Pretorius—former student of Choptuik--

first “long term” (many orbits) evolution of

black holes orbiting each other.
