What are your favorite educational youtube channels?
I'm thinking of starting an educational channel where it's only an audio voice over. Similar to 3blue1brown or primer, maybe with some narrator avatar. However, I don't like how some of the text appears on the screen in their videos, so I'm trying to get ideas from channels I haven't seen before.
Also, what topics in science and math do you think would make a good video, but don't exist yet?
