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.
It has taken thousands of generations and countless migrations to explore our own small planet. Now, in less than one lifetime, our robot surrogates have ventured to nearly every significant object in the solar system. Vast new territories and landscapes have opened up before our eyes. The experience has transformed the way we understand our species and its place in the universe. It may yet uncover alien life. Join scientists in a discussion of what we are learning today from worlds beyond Earth and find out where this effort is likely to lead us next.
Three profound transformations are under way on Earth right now. Climate change is real and is pushing us toward managing the planet as a whole. Urbanization—half the world’s population now lives in cities, and eighty percent will by midcentury—is altering humanity’s land impact and wealth. And biotechnology is becoming the world’s dominant engineering tool. In light of these changes, environmentalists are going to have to reverse some longheld opinions and embrace tools that they have traditionally distrusted.
From prehistoric times onward, people have always found ways to incorporate mathematical thinking into art. Today, we have sophisticated mathematical machinery that we can use both to understand the rules that underlie historical patterns and to describe new designs of great beauty and originality. Better yet, computers can serve as a powerful artistic tool, helping make these mathematical visions a reality. This talk will explore some of the exciting contemporary work that lies in the intersection of mathematics and art.
Quantum Physics. Along with neuroscience and rocket science, it has a reputation of being abstract, inpenetrable and horrendously complicated. Even Einstein himself struggled to get his head around it. But, there’s hope! Using references from movies, books and art, this presentation will guide you through the quantum world and give an overview of science’s best theory of the subatomic world to date. Prepare yourself for a mind-bending journey.
From the Enlightenment onward, science gained our trust and we followed its logic readily. But in an increasingly complex and skeptical world, will advancements in genetics, Artificial Intelligence, and countless other endeavours keep us believing, or will we lose the taste for a life shaped by science and technology?

Activity recorded from neurons in the brain often looks random or chaotic. How do we make sense of the world and produce precisely controlled responses when so much of the activity in our brains is chaotic? This talk will show how brain circuits can switch between chaotic and well-controlled patterns of activity, illustrating these points with computer demonstrations of network models. This talk will also discuss how chaotic activity may be useful for a healthy brain function and demonstrate what goes wrong when activity is insufficiently chaotic.
How will robotics change us and our lives? Will AI driven robots put us on and accelerated evolutionary path? Why would we want a more heavily robotized society? Do we have choice in the matter? Be part of the live studio audience for this special edition of TVO's Agenda with Steve Paikin.
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.
