Public Lectures Here is a wonderful collection of physics lectures. Another indication of the web sharing that so rapidly is extending the university to the people.
Here's their self description: "Perimeter Institute is a major centre for theoretical physics research, attracting a diverse community of resident and visiting scientists from around the world. They cluster in Waterloo, Ontario, to forge new, mind-bending ideas about the ultimate nature of our universe, from space and time to matter and forces. Driven by curiosity, their mission is to unlock nature’s most profound secrets hidden deep inside the atom and far across the universe."
