# Free resources on theoretical physics.

## A collection of high quality video lectures and notes. (Last revised: September 15th, 2019)

The following is a collection of high quality video lectures, and accompanying notes, on theoretical physics. All of the resources are freely available on the Web. Every resource has been reviewed, and should allow you to make "quick" progress in fundamental physics. It should be possible to more or less work your way downwards through the list of material. You should find the additional articles very helpful in developing your understanding.

If you have successfully completed a college course in mathematics / physics you could definitely work your way through the material on this website in just a few years. You would then be able to follow progress in fundamental physics at CERN, LIGO etc.
