# 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.

## The Big Bang

Wednesday Nov 02, 2005
Speaker(s):

Simon Singh grew up in Somerset, and completed his undergraduate work at Imperial College London, and his Ph.D. at Cambridge University and CERN. He has worked with the BBCs Science Department since 1990. In 1996, Singh directed the award-winning documentary Fermats Last Theorem. The documentary was also nominated for an Emmy under the American title The Proof. He is the author of three books, most recently, the Big Bang, a history of cosmology.

## Acceleration of highest energy cosmic rays

Tuesday Nov 01, 2005
Speaker(s):

Highest energy cosmic rays reach {\it macroscopic} energies $> 10^{20}$ eV ($\sim 10$ joules; corresponding linear momentum in one proton is similar to a slapshot hockey puck's). Such protons can either be accelerated by nearby astrophysical sources or be by-products of decay of unknown superheavy fundamental particles. After reviewing phenomenology of cosmic rays, I will discuss a novel {\it non-stochastic} acceleration mechanism in jets of powerful active galactic nuclei. The mystery of ultra high energy cosmic rays is likely soon to be resolved by Pierre Auger observatory.

## Meet the \'Other\' Einstein

Sunday Oct 23, 2005
Speaker(s):

It is well known that Einstein worked to develop a unified field theory that would encompass all of physics including (he hoped) all quantum phenomena. It is not so well known that there was \'another Einstein,\' who from 1916 on was skeptical about the continuum as a foundational element in physics, especially because of the existence of quantum phenomena.

## Faster than the Speed of Light: Could the Laws of Physics Change?

Saturday Oct 22, 2005
Speaker(s):

Could the laws of physics change? The laws of physics are usually meant to be set in stone; variability is not usually part of physics. Yet contradicting Einstein\'s tenet of the constancy of the speed of light raises nothing less than that possibility. I will discuss some of the more dramatic implications of a varying speed of light.

## Einstein, Picasso: Space, Time and the Beauty that Causes Havoc

Monday Oct 17, 2005

The most important scientist of the twentieth century, and its most important artist, went through their periods of greatest creativity almost simultaneously and in remarkably similar circumstances: Einstein\'s special theory of relativity and Picasso\'s Les Demoiselles d\'Avignon. It turns out they were both working on the same problem: the nature of space and time and, more particularly, simultaneity.
