A Plethora of Math Videos
A few weeks ago, I reviewed access to a "plethora" of videos related to the History of Mathematics. I discovered it via a much broader Pinterest resource.
Consider the full Pinterest collection of videos on Mathematics itself. A lot of options....most of them videos of lectures offered by mathematicians. Be forewarned that some get too esoteric, some get too narrow in focus or specialized, some have "aire's" ...but many are quite good.
Since I do not know your individual tastes, you will have to browse on your own. Again, listen in on a video...and if it gets too dry...skip ahead in that video or move on to another one. You will find something of interest....and perhaps learn or relearn some interesting mathematics along the way.
