Video Lectures on Quantum Field Theory
These are videos of the lectures given at the Perimeter Institute PSI
programme in 2009. Each video is in wmv format and somewhere
around 130 Mb.
More formats are available for download at the Perimeter Institute webpage
The lectures follow the printed notes which are available on the main quantum field theory webpage.
