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 mysteries of quantum theory run deep. Despite 80 years of research, there is still no consensus on its interpretation. This talk will explore some of the important issues in the foundations of quantum theory, from the idea that we have only a limited knowledge of a deeper reality, like the prisoner in Platoâs cave who sees only the shadows of objects and never the objects themselves, to John Bellâs famous discovery of the difference between quantum correlations and Dr.
Where does technology come from? Physics! Exploring basic mysteries such as "What is light?", "How can atoms exist?", and "What is space and time?" led to computers, wireless communication, mp3 players, lasers, medical imaging - indeed, virtually every "high tech" device on the planet. Join us in a celebration of the immense power of theoretical physics to transform our world for the betterment of humanity, and learn how current theoretical explorations may hold potential for even more fantastic innovations in the future.
Science journalism is the essential glue connecting science to society. Looking around the world, how is science journalism changing? Is science journalism even essential to good science communication? How else might scientists come to understand the relationship between new technologies and the products of research and the public who will ultimately use them?
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? Be part of the live studio audience for this special edition of TVO's Agenda with Steve Paikin.
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.
