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 world as experienced by single atoms is radically different from the everyday world we, as gigantic humans, are used to: the laws of quantum mechanics replace the laws of classical physics. Because the quantum realm is alien from our daily experience, many common quantum effects are surprising and unintuitive. To understand the quantum world, it may be better to just start from scratch, as a child might, and develop intuition about the behavior of quantum objects by simply looking at a series of quantum examples rather than trying to analogize with classical physics.
