Rated 5 out of 5 by from Prof. Ball and "The Nature of Matter" I have viewed lectures 1 -7. I view each twice and read the lecture notes for each chapter after the second viewing. I took first year university chemistry 35 years ago, and I thought this course would be a nice review. Much of the course content so far (lecture 7) is very basic, and much of it I still remember, but there are some nice details and ideas that were new to me. Prof Ball is very good, and you can tell he likes his subject and knows alot about it. My only minor complaint is that there should be more illustrations, or possibly even demonstrations. This course is like basic first year chemistry, but without any quantitative analysis. You could say that it is a chemistry course for people who think they cannot do mathematical or symbolic reasoning.

Discover how the immense variety of matter-stars, mountains, plants, people-is made by a limited number of elements that combine in simple ways. In the engaging lectures of The Nature of Matter, no scientific background is needed to appreciate everyday miracles like a bouncing rubber ball or water's astonishing power to dissolve. Knowledge of materials drives the development of civilization. Where will we go next?
