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.

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!

The problem of vacuum energy is reviewed. The observational evidence in favor of a non-zero cosmological constant is described. I then discuss several possible explanations for how a theoretically natural huge value of vacuum energy could be adjusted down to the unnaturally tiny but observed value.

At the turn of the century, numerous figures were attempting to form a new unitary science of psychology, modelled on how they imagined sciences like physics and chemistry functioned, with the discovery of universal laws and discoverers who would be proclaimed to be on the scale of Copernicus and Newton. It was intended that the formation of this new science would be nothing less than the completion of the scientific revolution, and that as a consequence, it would transform psychiatry, psychotherapy, the human sciences and indeed, all walks of life.

Few, if any, papers have attracted as much attention as Einstein’s June paper on the Special Theory of Relativity and no equation of physics has become part of common discourse except for the equation Einstein presented in his September paper: E = mc2. The concepts of space and time are ubiquitous in physics and, since the Special Theory of Relativity fundamentally altered these concepts, the impact of the June paper on physics has been pervasive. With the additional assertion, made in the June paper, that the speed of light is a constant for all observers, time and space became relative.
