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.

For more than 70 years, astronomers have had the uneasy suspicion that there was more to the universe than met the eye - much, much more. In the past five years, this suspicion has become a certainty. We now know for sure that normal matter and normal radiation account for only 4% of the density of the universe. One of the two biggest components, dark matter, may be finally be identified by new experiments coming on line next year. I\'ll summarise the long quest to identify dark matter and our prospects for finally achieving this goal in the next two years.

This talk discusses Einstein\'s special and general theories of relativity in a simple manner. Some simple mathematical arguments are included. This leads to a brief description of Loop Quantum Gravity - one of the most popular way of trying to describe gravity using the ideas of quantum mechanics. In addition, the Standard model of particle physics, which describes all known particles and their (non-gravitational) interactions is explained. We conclude with a description of some recent research which may bring the Standard Model and Loop Quantum Gravity together into a single theory.

The world at the size of individual atoms obeys very different laws of physics from those we are used to in the everyday world around us. Quantum mechanics rules, allowing atoms to be, in some sense, in more than one place at a time. Researchers all over the world are working to build \"quantum computers\" whose memories manipulate an inherently new type of information, \"quantum information.\"

One simple way to think about physics is in terms of information. We gain information about physical systems by observing them, and with luck this data allows us to predict what they will do next. Quantum mechanics doesn\'t just change the rules about how physical objects behave - it changes the rules about how information behaves. In this talk we explore what quantum information is, and how strangely it differs from our intuitions.
