Video Library

Since 2002 Perimeter Institute has been recording seminars, conference talks, and public outreach events using video cameras installed in our lecture theatres.  Perimeter now has 7 formal presentation spaces for its many scientific conferences, seminars, workshops and educational outreach activities, all with advanced audio-visual technical capabilities.  Recordings of events in these areas are all available On-Demand from this Video Library and on Perimeter Institute Recorded Seminar Archive (PIRSA)PIRSA is a permanent, free, searchable, and citable archive of recorded seminars from relevant bodies in physics. This resource has been partially modelled after Cornell University's arXiv.org.

Motivated by the goal of self-consistently calculating self-force-corrected orbits and waveforms with (3+1) evolution codes we derive a covariant expression for a non-singular representation of a scalar point charge moving along a geodesic of an arbitrary spacetime. This differs from previous representations that were anchored to the use a particular locally-inertial coordinate system.
