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.

We show that the entropy resulting from the counting of microstates of non extremal black holes using field theory duals of string theories can be interpreted as arising from entanglement. The conditions for making such an interpretation consistent are discussed. First, we interpret the entropy (and thermodynamics) of spacetimes with non degenerate, bifurcating Killing horizons as arising from entanglement. We use a path integral method to define the Hartle-Hawking vacuum state in such spacetimes and discuss explicitly its entangled nature and its relation to the geometry.

In 1905, Norwegian explorer Roald Amundsen completed the first ever transit of the fabled Northwest Passage, culminating a centuries long quest that had claimed ships and lives. Amundsen\'s feat was one of many human achievements in the first decade of the new century, and a landmark in the history exploration. Amundsen\'s voyage was preceded by the controversial North Pole expedition of Robert Peary, another long sought prize of explorers.

Albert Einstein worked in the Swiss Patent Office in 1905. What was the new world of technology that a patent examiner would have confronted in the young century? Robert Friedel, historian of technology and author of several books on inventions of this period shows why this period a century ago was as exciting and disorienting an age of technological change as our own--maybe even more so!
