# Free resources on theoretical physics.

## A collection of high quality video lectures and notes. (Last revised: January, 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.

You can also a find a large collection of curated videos on my youtube channel. If you have a physics question you can ask it me on Quora. I also have a small collection of **physics books for sale** (only need my electronic versions) so if you need further reading material on quantum field theory, supersymmetry or string theory, let me know what books you are looking to purchase [email protected] and I'll see if I have something you may find interesting.
