About this course
Chemistry offers us a way of understanding the world in which we live. Chemistry provides us with insights into how our bodies function; the ingredients that are contained within the foods we eat; the reason cars, planes and trains are able to run as efficiently as they do; the manner in which computers are built and operate; and the materials used to construct our homes and buildings within our communities. Knowing something about chemistry is worthwhile because it provides an excellent basis for understanding the physical universe we live in. For better or for worse, everything is chemical.
