    Mans explaining with 3 markers and a chopstick and its clearer than any professor could explain with slides and computers and simulations
    Youre an amazing teacher

      You either are simply lying or you are massively overestimating what you are able to do after watching this video. In University you learn this concepts in a formal, rigorous way. You learn the proofs, definitions, etc.
      Pretending this is in anyway a substitute for any university lesson is just plain dumb.
      It's a complement, for sure.

      @@samuelwittlinger7790 I am a maths graduate student. Saying you don't learn intuition in university is just insane to me. Whenever you learn a topic, you always start with the geometric explanations, whenever possible. You learn the intuitive way, and you learn that the intuitive way is not enough to make a general statement, which is why you need the rigorous proofs.
