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 syntax of economic theory closely resembles the syntax of physics. But physics deals with what seems to be the objective world. In contrast, the essence of economics is subjectivity and moral choice. What can you reasonably expect from treating economics as a branch of science? This talk compares the nature and efficacy of models in both physics and finance, and tries to reach a sane answer to the question above.
