Video Library

Since 2002 Perimeter Institute has been recording seminars, conference talks, public outreach events such as talks from top scientists 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 and 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. 

Accessibly by anyone with internet, Perimeter aims to share the power and wonder of science with this free library.

Black holes are the elementary particles of gravity, the
final state of sufficiently massive stars and of energetic collisions. With a
forty-year long history, black hole physics is a fully-blossomed field which
promises to embrace several branches of theoretical physics. Here I review the
main developments in highly dynamical black holes with an emphasis on high
energy black hole collisions and probes of particle physics via superradiance.

I discuss several recent efforts
in relating string field theory calculations of BMN BMN BMN and BMN BMN BPS
correlation functions to direct perturbative calculations and
integrability-assisted methods. I review the next-to-leading order agreement
between strings and perturbation theory in the SO(6) sector, a conjectured
extension of the integrability techniques by Escobedo, Gromov, Sever, Vieira from
the SU(2) to the full SO(6) sector and agreement with SFT and PT in it at the

Physics
is at a crossroad that leads either to Naturalness or the Multiverse. While the
confirmation of gauge coupling unification in the early 90s gave a tremendous
boost to naturalness and to low energy SUSY, the lack of evidence
for new physics beyond the standard model at the LHC points to a paucity of new
particles near the weak scale. This suggests that the weak scale is tuned and
that supersymmetry, if present at all, is realized at higher energies. This

The bimodality of gamma-ray burst (GRB) durations points
to distinct progenitor classes for the long- and short-duration GRBs. While the
progenitors of long-duration GRBs are now known to be massive stars, the
progenitors of short-duration GRBs remain unidentified. In this talk I will
discuss the discovery of short GRB afterglow and their host galaxies, detailed
studies of their environments from parsec to galactic scales, and studies of
their energetics and beaming. Taken together, these observations point to the
