YouTube Playlist: Really Interesting Videos (long ones)

This is a longform version of this. Again, these videos are part of the resources I make available to students are various YouTube playlists. This one is for videos that are – as the playlist’s name suggests – really interesting, but long. They are at least 2o mins with the longest going for more than an hour. While they do not cover any specific disciplines but can inform your practice.  (If I can find the time, I will try to provide a bit of context for each in a separate post).
