Professor Dave Feldman is an excellent teacher. He knows exactly what pace to proceed at, what to repeat more than once, and what thoughts/questions the student must have who is watching. He introduces humour as he goes along which is also great to keep things real almost giving a feeling of being in the room with him. I read the book "Chaos" almost 30 years ago and it was great taking this course now to formalize what I read back then. I am looking forward to doing more courses taught by him and also hope that other courses on the Complexity Explorer site are taught as well as this was.
