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 Internet promises the realization of two of humanity's noblest dreams: universal access to all human knowledge and the capacity to form and coordinate groups at virtually no cost. As great as this sounds, it's bad news for certain kinds of top-heavy organizations and the kinds of companies that got rich on exclusion from information. From the UN to shady back-room "plurilateral" treaty negotiations, from the blogosphere to staid standards-committees, the fight over the future rages, with diplomacy and activism at its core.
Are we ready to come face to face with our innermost genetic secrets? Will this knowledge help us make wise choices? Can we trust ourselves and others with safeguarding this most potent knowledge? Be part of the live studio audience for this special edition of TVO's Agenda with Steve Paikin.
The search for the origins of species has entailed a series of great adventures over the past 200 years. This talk will chronicle the exploits of a group of explorers who walked where no one had walked, saw what no one had seen, and thought what no one else had thought. Their achievements sparked a revolution that changed, profoundly and forever, our perception of the living world and our place within it.
With studies suggesting the vocabularies of young people today are shrinking and some university professors claiming the essay is hardly worth assigning anymore due to shortened attention spans, some wonder whether technology has done more harm to our kids than good. Our panel of experts will debate the issue.
In our lifetime we have seen a broad transformation in the way we interact with technology in our daily lives. And further developments in technology promise a continued impact. Are we comfortable living in a world that never shuts off? How has this technology affected us, our thinking, our relationships and the way our work works? Is technological progress always for the better? Be part of the live studio audience for this special edition of TVO's Agenda with Steve Paikin.
Computer science has served to isolate programs and programmers from knowledge of the mechanisms used to manipulate information, however this fiction is increasingly hard to maintain as devices scale down in size and systems scale up in complexity. This talk will explore the consequences of exposing rather than hiding this underlying physical reality, in areas including logic automata, interdevice internetworking, intelligent infrastructure, digital fabrication and programmable matter.
Recently there has been great interest in calculating transport coefficients for field theories at large coupling, using AdS/CFT. In this talk I will discuss recent work showing how to use the membrane paradigm to easily compute the shear viscosity and conductivity in arbitrary gravity theories. In a certain sense these can be thought of as effective couplings at the black hole horizon dual to the field theory plasma. An explicit Wald-like formula for these couplings is given for a large class of generalized gravity theories.
