Explanation of physics video lists

Starting in July 2019, I began making posts where I would organize physics videos from a single YouTube channel into 20 physics sections. The sections are based on a physics outline I created in an earlier post which can be found at this link. Below is a list of the posts I've created using this format.


One of my goals is to build an outline of the principles of physics. I believe that making these video lists has helped me progress towards this goal. It has been useful to analyze these channels and organize the videos according to the 20 sections in the outline.
