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.
Our understanding of the physical world at the most fundamental level is based on two theories: quantum theory and general relativity. They are impressively successful when each is considered on its own, but in situations where both play a role, we are reduced to puzzles and absurdity. To the great frustration of researchers, candidate theories of quantum gravity produce more puzzles than answers. We shall tour of some of the problems, focusing on the role of spacetime and causality.
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.
