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.
If we are to advance technological systems for a low carbon and
electrified future, how do we measure progress? Through animated videos
and a panel discussion with energy experts, this kick-off session
introduces some of the technological challenges and implementation
hurdles to be overcome if we are to meet our future electricity needs.
Speakers include:Barry Brook, Walt Patterson, Jatin Nathwani, and Robin Batterham
His Excellency the Right Honourable David Johnston, Governor General of
Canada, officially launches the Equinox Summit: Energy 2030 with a
challenge for Summit participants, as well as those across the globe, to
inspire innovation through intense collaboration and explore tools and
strategies to lessen our impact on the Earth.
The gauge/gravity duality may give a nonperturbative formulation of superstring/M theory, and hence, if one can study the nonperturbative dynamics of the gauge theory, it would be useful to understand the nonperturbative aspects of superstring theory.
I belong to the lucky generation who survived World War Two and
unexpectedly found ourselves alive and young at the dawn of four
simultaneous revolutions. We were present at the creation of four new
technologies that were to continue transforming the world for the
following sixty-five years. First revolution, Space, beginning with the
first spacecraft, the V2 rocket, which came crashing down on our heads
in London in the last year of the war. Second revolution, Nuclear
Tensor network algorithms are a powerful technique for the study of quantum systems in condensed matter physics. In this short series of lectures, I will present an applied perspective on tensor network algorithms.

Though the observed CMB is at very low energy, it encodes ultra high-energy physics in spatial variations of the photon temperature and polarization fluctuations. This effect is believed to be dominated by the initial quantum state of the Universe. I will describe the first theoretical tools by which to construct such a state from fundamental physics.

Recently, several neutrino physics has witnessed an accumulation of anomalous results. In the first part of this talk, we will discuss the tension that the MINOS experiments has seen between oscillations of neutrinos and anti-neutrinos. We will show that, phenomenologically, this tension can be explained if neutrinos are hypothesized to have new interactions mediated by higher-dimensional operators, but we will also show that problems arise when one attempts to embed these operators into renormalizable models.
