    I think you are currently the best teacher available on youtube, whenever i search for any topic and your video reference comes, I usually choose that. I dont have to navigate to other videos then. MY query is definitely resolved. (no navigation and time wasting is best part , with efficient examples)

    They are teaching this first half-year in university in Germany, and I could puke seeing "teachers" pulling out masses of actual code or formulas to explain this to newcomers. You used lenguage and an easy to overlook table and that is exactly the right way
