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.

With a background in computer and systems engineering as well as language processing and automatic speech recognition, Ms. Payette was selected from a pool of 5,330 candidates to become a Canadian astronaut, focusing on technical issues in robotics. Today, following her amazing professional career and numerous life experiences, Ms. Payette is veteran of two missions to the International Space Station as a crew member and Flight Engineer.

The world's most ambitious scientific experiment is buried 100 meters underground, straddling Switzerland and France. A billion times every minute, the Large Hadron Collider (LHC) slams together protons, while four giant detectors watch closely.

Learn about the future of “3D Printers” – machines that will fabricate arbitrary-shaped parts, layer by layer. Dr. Lipson will share a history of these technologies and preview a future in which we continue to gain unprecedented control over physical matter. If humans distinguish themselves from their evolutionary ancestors by making tools, then how might the ultimate tools – involving additive manufacturing – impact human culture forever? Dr. Lipson explores the science, technology and potential of programmable matter.

Some numbers mean things, and some numbers do things. Making--and breaking--that distinction was central to renowned mathematician John von Neumann’s implementation of Alan Turing’s Universal Machine in 1945-56. In this lecture, you will learn about the unlikeliest place on earth to build such a device and how this vital 5-kilobyte step in the digital revolution was sparked by a collision of ideas between mathematicians and engineers.

We investigate the entanglement spectra of topological insulators which have gapless edge states on their spatial boundaries. In the physical energy spectrum, a subset of the edge states that intersect the Fermi level translates to discontinuities in the trace of the single-particle entanglement spectrum, which we call a `trace index'. We find that any free-fermion topological insulator that exhibits spectral flow has a non-vanishing trace index, which provides us with a new description of topological invariants.
