# 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
here.

The lectures follow the printed notes which are available on the main
quantum field theory webpage.

### Lecture 1

Introductory remarks on quantum field theory and classical field theory, roughly covering pages 1-10 of the printed notes.

### Lecture 3

A few last comments on classical field theory. The beginning of canonical quantization for the free scalar field. Roughly pages 18-24 of the printed notes.

### Lecture 4

More on canonical quantization, including normal ordering, the vacuum and the interpretation of particles. Pages 25-33

### Lecture 5

Yet more canonical quantization, including the Heisenberg picture and causality. Pages 34-38.

### Lecture 9

Finishing off scattering amplitudes. A look at the algebra of the Lorentz group. Roughly pages 62-69 and 81-84

### Lecture 11

Solving the Dirac equation and a first look at quantization and statistics. Various bits from pages 90-108
