Your videos are great to watch and learn science subjects. In fact, I am interested to keep your entire lectures on DVDs, for my children and grandchildren and also for their grandchildren.

Please keep it growing for the sake of humanity and science.

You got three dumbs down but I think that was some really good advice. memorization can really get in the way of real learning. The kind of learning you won't soon forget or fall asleep doing it.

@nicoloco3625 I suppose you make a point, but for me these videos serve as reminders and reinforce my concepts. The fact that he related each equation, makes deriving equations quite intuitive.
