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.
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.
Commitment to space travel has ebbed and flowed. Physicist Stephen Hawking believes the way to ensure human survival is to continue space exploration. Critics of space travel argue that Planet Earth is in dire need of our attention and resources right now. Is there a trade-off between going to space and fighting climate change, overpopulation and other earthly concerns?

Over the last decade our picture of the universe has changed almost as much as it had in the preceding century. As a result, our picture of the future, both of the universe, and life within it, has dramatically altered as well. This talk will begin by reviewing the recent revolutionary developments in cosmology, and then address several fascinating questions that have arisen as a result of our discovery that the dominant energy of the universe resides in empty space: Can life be eternal in an eternally expanding universe,? Are the laws of physics tailored for the existence of life?
You've heard the physicists speculate on parallel universes, space travel, and time travel. Now come and hear a physicist interview the real experts in these subjects: a bestselling science fiction writer and pioneer of virtual reality discuss what you get when you look at science through fiction.
What do we really know about the universe? What mysteries are today's top cosmologists investigating? Join a discussion with leading cosmologists to hear fresh perspectives on some of the deepest questions in modern science: What is the mysterious dark matter that fills intergalactic space? Was there another universe before the big bang, and what will happen to ours in the distant future?
This panel will explore some of the deepest questions facing those who would harness the power of quantum mechanics in new quantum technologies: What are the newest and most interesting discoveries researchers have made about quantum information? What progress has been made in recent years towards experimentally harnessing quantum devices for quantum computation? What are the main motivations for building quantum information processing technologies? Drs. Aharonov and Shor appear courtesy of Institute for Quantum Computing.
