David spent the last week having a great time visiting the Black Hole Initiative (BHI) at Harvard. As part of his visit he gave two talks at the "Foundations Seminar," first giving an introduction to the science of numerical relativity before giving an overview of the Black Hole Threshold, the region of solution space in GR that lies between collapse and dispersion. Here he is hanging out with Dr. Prashant Kocherlakota, one of the BHI researchers.
