This was the most calm and kind lecture. There is no reason to hesitate and not watch this lecture because the progress is slower than other lectures and there are many lectures. You must watch it! It was the most satisfying among other basic lectures (that I have experienced). It was a pity that there were sometimes gaps in the middle because it was in a full lecture format (because there was no editing). The last three or so lectures were cut and uploaded. Please refer to them if you are taking the class. After the basics, I have to go listen to the practical part!
