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.

Sarah Croke - is a postdoctoral researcher at Perimeter Institute. From Ireland and the UK originally, she received a BSc in Physics and Applied Mathematics from University College Cork, Ireland in 2003. After a brief stint as a radio astronomer, completing an MSc in Astrophysics, she studied Quantum Information and Quantum Optics under the supervision of Prof Stephen Barnett at the University of Strathclyde, UK, receiving a PhD in 2007. She has been a postdoc at PI since November 2007. She works in quantum information theory, and is interested in both theoretical and experimental aspects.

A number of recent proposals for a quantum theory of gravity are based on the idea that spacetime geometry and gravity are derivative concepts and only apply at an approximate level. Two fundamental challenges to any such approach are, at the conceptual level, the role of time in the emergent context and, technically, the fact that the lack of a fundamental spacetime makes difficult the straightforward application of well-known methods of statistical physics and quantum field theory to the problem.

Speaker(s): 

Throughout history science has aimed at unification, whereby more phenomena are explained by more fundamental theories with simpler principles. We will discuss how string theory aims at being the ultimate unified theory of all elementary forces in nature.
