I viewed this brilliant series as a set of 4 DVD's and was stunned by the brilliance of Dr. Jacob Bronowski as a teacher. He deals with every subject imaginable, including scientific work which ordinarily, I would not have attempted to follow, but he makes it all so easy that you begin to feel quite clever and to wish that you'd had him as a tutor. The series was 3 years in the making with location filming in over 20 countries and I would energetically recommend it to anyone to broaden their knowledge and especially to those with children, who will, I promise, be fascinated by all the events which shaped the world as we know it...an absolute masterpiece!
