Chemistry. Unit 1, Matter and the rise of atomic theory : the art of the meticulous / [produced by the Science Media Group at the Harvard-Smithsonian Center for Astrophysics]
This program traces the story of how humans have always practiced chemistry; how, over time, it developed from a practical discipline into a science. Today, we keep up the chemists' tradition to refine and purify substances. A current, real-life application of the "art of the meticulous" is the refining and purification of pure silicon from a common material--silica sand--for advanced electronics, such as cell phones and solar cells
