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

The Polchinski equations for the Wilsonian renormalization group in the $D$--dimensional matrix scalar field theory can be written at large $N$ in a Hamiltonian form. The Hamiltonian defines evolution along one extra holographic dimension (energy scale) and can be found exactly for the subsector of $Tr\phi^n$ (for all $n$) operators. We show that at low energies independently of the dimensionality $D$ the Hamiltonian system in question reduces to the {\it integrable} effective theory.

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.

How hopeful can we be about new technologies paving a path away from our
current reliance on oil-based energy? Energy experts investigate the
alternatives in a moderated discussion presented live on TVO’s The Agenda with Steve Paikin. Speakers include: Barry Brook, Walt Patterson, Tom Rand, Zoë Caron, and Jatin Nathwani


Thursday Jun 09, 2011

As the world’s population inches toward the 8 billion mark, energy
experts look at how supply and demand of energy will affect global
economics and politics in a moderated discussion on TVO’s The Agenda with Steve Paikin. Speakers include: Jason Blackstock, Jian hua Ding, Velma McColl, Vagish Sharma, and Jose Maria Valenzuela

Born from a unique, international energy summit of scientists,
engineers, entrepreneurs and future leaders from around the world, the
Equinox Communiqué offers visionary proposals for transformative action
on reducing the electricity-related emissions that drive climate change.
Through a series of mini presentations, Summit participants discuss
the Equinox Summit: Energy 2030 and explain the six main recommendations
outlined in the Equinox Communiqué. These speakers lay the groundwork

From the buildings we live in to the places we work — we use a lot of
energy to keep our habitats lit, warm and efficient. Is there a better
way? Energy experts participate in a moderated discussion presented live
on TVO’s The Agenda with Steve Paikin. Speakers include: Cathy Foley, Maria Skyllas-Kazacos, David Keith, Jatin Nathwani, and Terri Meyer Boake

As humans, we have developed technologies to control energy
transformations from agriculture to nuclear weapons. Increasing
technological ability has co-evolved with increasing intensity of energy
use and growing complexity of our civilization. These forces have
shaped our environmental footprint and our very conception of nature.
It's tempting to believe that physical limits constrain our energy
and environmental choices as never before; but Dr. Keith argues
precisely the opposite: our growing technological leverage makes access


Wednesday Jun 08, 2011

Today we rely on just-in-time delivery of electricity that is sometimes
vulnerable to natural disasters and failure at peak demand. This plenary
session examines the reliability, resiliency and security of emerging
technologies in an increasingly electrified energy system. Speakers
include: Bill Rosehart, Maria Skyllas-Kazacos, Ted Sargent, and Walt


Tuesday Jun 07, 2011

Trains, planes and automobiles — what are we doing to find new resources
and modes of transportation? And will it lead us to rethink how we
live? Energy experts participate in a moderated discussion presented
live on TVO’s The Agenda with Steve Paikin. Speakers include: David Keith, Greg Naterer, Maria Skyllas-Kazacos, Aaron Leopold, and Jeff Casello
