Ask HN: Favorite teachers on YouTube? Currently I am watching Daniel Shiffman (example : https://www.youtube.com/watch?v=_p5IH0L63wo) and I really like his enthusiasm. I've watched a whole bunch of high production, paid courses (udemy, udacity etc) and somehow Shiffman's free videos are more fun to watch and learn. Any other teachers you like? Doesn't need to be math or computers, other subjects welcome too more
